    Description

    BACKGROUND OF THE DISCLOSURE



    [0001] The disclosure relates generally to the field of surgical instrumentation and more particularly, to a suction device to be used with a tongue blade device for evacuating cauterization tissue and fumes from a patient's mouth during oral laser surgery.

    [0002] Electrocautery devices and surgical lasers are typically used for cutting or ablating tissues in various confined body cavities. For example, in the surgical treatment of snoring, the surgeon performs a vertical resection of the soft palate on both sides of the uvula, sparing the uvula itself, with further ablation with the laser of the lateral and inferior sides of the uvula to create a "new uvula" that is higher and smaller (uvulopalatoplasty). Electrocautery devices and surgical lasers are also used for reshaping or removing the tonsils (tonsillectomy), and for removing or reshaping posterior parts of the tongue (glossectomy).

    [0003] During such applications of electrocautery devices and surgical lasers, it is desirable and necessary that the work area be maintained as free from smoke and vaporized tissue as possible. A tongue blade evacuation system can be provided as shown in U.S. Patent No. 5,460,626. It is also necessary that the patient's tongue be kept away from the working area. These requirements are necessary to provide a clear view of the working area for the surgeon.

    [0004] While existing pharyngeal handpieces remove some of the smoke and vaporized tissue during laser application, they do not remove it rapidly enough to keep the area fully visible for the doctor or to prevent contamination of the lens. Additionally, while existing tongue depressors prevent the patient's tongue from interfering with the operation, they occupy one of the surgeon's hands while not effectively assisting with removal of fumes and tissue during surgery. Further, while the foregoing problems are particularly troublesome with respect to the above described applications for surgical lasers, they are also present to some degree in many other applications of surgical lasers.

    [0005] In a preferred embodiment, the device is a tongue blade used with a Mclvor mouthgag. The device is used intraoperatively to retract the tongue and mandible and open the mouth for surgeries involving the oral cavity/oropharynx. The device is preferably a one-piece surgical stainless steel unit with a built-in suction tube to evacuate any anesthetic gases or noxious/dangerous fumes or plumes generated by electrocautery, or other similar devices. This serves as a protective feature to help ensure the safety of the Operating Room Staff and the patient. It can also be used to oxygenate or jet ventilate a patient intraoperatively by passing oxygen through the suction passage down into the oral cavity/oropharynx. There can be two other variations of the device: a high impact plastic model that is disposable, and a stainless steel model with a removable, disposable suction tubing.

    [0006] It is accordingly an object of the present disclosure to provide a tongue blade suction device for eliminating or reducing the foregoing problems during surgical applications while providing better overall results.

    [0007] US4947896 discloses a laryngoscope having a blade and a removably attached handle, which can be fixed to the blade at a desired angle. An adjustable position suction tube is entrained in the blade with an adjustment actuator supported on the handle.

    [0008] US5078602 discloses a saliva ejector including a hollow tube soldered to a side of a tongue protector.

    [0009] US6254591 discloses a medical scavenger suction device which includes a tubing assembly having a primary tube and two or more auxiliary tube members. The tubing assembly is integrally formed within an endotracheal tube sidewall or formed integrally with a mouth gag device. The tubing assembly is adapted to connect to standard wall suction tubing to enable the exhausting of gas and/or smoke from the surgical area.

    [0010] US1613373 discloses a combined suction tube and tongue depressor.

    [0011] US4215984 discloses a dental suction device is provided in which the generally hollow U-shaped base of the device is designed to be positioned in a patient's lower jaw area inside the lower row of teeth. The base is connected to a hollow, curved stem which can be connected to a suction source. Slots in the base are utilized to ingest excess moisture present in a patient's mouth during dental procedures. The device also has a flat plate attached to the base which acts as a tongue depressor and an adjustable tooth rest on the stem on which a patient's upper maxillary incisal teeth rest during dental procedures.

    [0012] US2010121152 discloses a laryngoscope with a suction catheter assembly that includes a catheter to supply suction for removal of fluids proximate to the distal end of the blade of the laryngoscope during intubation. A connector secures the catheter to the distal end of the blade. A retainer holds the catheter against the side of the blade.

    [0013] US2007287888 discloses a suction unit which is placed inside the handle of a laryngoscope to allow portable suction to be utilized during intubation without requiring multiple devices. The suction tip can be attached to the distal end of the laryngoscope blade.

    SUMMARY OF THE DISCLOSURE



    [0014] The present invention provides a suction device as defined in claim 1. Optional features are recited in dependent claims.

    [0015] The disclosure relates to an apparatus for removing noxious fumes. In particular, it relates to an apparatus for and a method which does not form part of the invention of removing noxious fumes, plumes generated by electrocautery, smoke and vaporized tissue from a patient's mouth and controlling a patient's tongue through the use of a one-piece tongue blade coupled with a suction device to form a single unit which can be used in and during surgical applications. Specifically, the disclosure includes a tongue blade coupled with a suction device.

    [0016] In accordance with one aspect of the disclosure, a suction device for evacuating fumes has a tongue depressor including a pair of opposed walls; a suction tube connected to the tongue depressor; an elongated support member to which the suction tube is connected; and a connecting member attached to an end of the suction tube for connecting the suction tube to a suction generating device.

    [0017] It is another object of the disclosure to provide a more efficient system for controlling a patient's tongue and for removing noxious fumes, smoke and vaporized tissue or plumes generated by electrocautery from a patient's mouth during surgery.

    [0018] It is another object of the disclosure to provide a device combining a tongue blade and suction device as a single tool to increase the rate of noxious fumes, smoke and vaporized tissue evacuation from a patient's mouth during surgery.

    DETAILED DESCRIPTION OF THE DISCLOSURE



    [0025] FIGS. 1-1C show illustrations of a preferred embodiment of the disclosure including a tongue blade 10 having a distal end 12 for inserting into a patient's mouth during a surgical application and a proximal end 14 coupled in fluid communication with a hollow tube 16. The tongue blade has a curved or rounded shape body 18 which acts as a tongue depressor and rests on the patient's tongue. The distal end 12 has a fork or U-shaped appearance formed by two protrusions 22, 24 (FIG. 1 B) extending therefrom which form a channel or opening 26. Protrusions 22, 24 extend or curve upwardly as seen in FIG. 1B.

    [0026] A disposable hollow plastic or rubber suction tube 16 is connected to an elongated spine 28 which is in communication with a barb or hollow connector 30. The spine is preferably formed from stainless steel or any other suitable material. The spine has a first elongated portion 31 and a shorter portion 33 which extends at about 90 degrees from end 35 of portion 31. Portion 33 has an opening 32 for receiving the tube 16 therethrough. Further, in the embodiment illustrated in FIG. 1C, the suction tube 16 has a receiving outlet member 34 having an opening 36 formed therethrough located adjacent to the proximal end 14 of the blade for removing anesthetic gases, noxious fumes, smoke, vaporized tissue, plumes generated by electrocautery and other debris from a patient's mouth during use in surgery.

    [0027] When in use, smoke, plumes generated by electrocautery, noxious fumes and vaporized tissue removal is effectuated by attaching barb or connector 30 to any pneumatic device (not shown) typical of the art which causes a suction effect from the tongue blade.

    [0028] While the surgical application is taking place, the spine 28, which is manually held in one of the doctor's hands, is held near the patient's mouth directing the suction tube 16 into the patient's mouth which removes smoke, fumes, plumes generated by electrocautery, and vaporized tissue from the patient's mouth using opening 36 (FIG. 1 B). Meanwhile, the tongue blade 10, which is connected to the tube, is in the patient's mouth controlling the patient's tongue, thus preventing the tongue from obstructing the application of the suction tube and removing smoke and vaporized tissue at the same time. The tongue blade suction tube 16 evacuates the smoke, fumes, plumes generated by electrocautery, and vaporized tissue by sucking it through the receiving port or opening 36, through tube 16, and out through any well known pneumatic or other suction causing device (not shown), attached to the tube barb 30.

    [0029] In a preferred embodiment, the device is a tongue blade 10 used with a Mclvor mouthgag. The device is used intraoperatively to retract the tongue and mandible and open the mouth for surgeries involving the oral cavity/oropharynx. The device 10 is preferably a one-piece surgical stainless steel tongue blade with a built-in suction tube 16 to evacuate any noxious/dangerous fumes or plumes generated by electrocautery, or other similar devices. This serves as a protective feature to help ensure the safety of the Operating Room Staff as well as the patient.

    [0030] Alternatively, the tongue blade and suction device can also be used to oxygenate or jet ventilate a patient intraoperatively by passing oxygen through the suction tube 16 down into the oral cavity/oropharynx through opening 36.

    [0031] FIGS. 2-2B and 3 show illustrations of an alternate configuration of the disclosure (not in accordance with the presently claimed invention) including a tongue blade 50 having a distal end 52 for inserting into a patient's mouth during a surgical application and a proximal end 54 coupled with a hollow tube receiving member 56 and an elongated support member or spine 70 via a curved connector 71. A substantially U-shaped opening 55 is formed near end 54. The tongue blade has a curved or rounded shape body 58 which acts as a tongue depressor and rests on the patient's tongue. The distal end 52 has a fork or U-shaped appearance formed by two protrusions or walls 60, 62 extending therefrom which form a rounded or curved channel 64 having opening 66. Walls 60, 62 curve upwardly as seen in FIG. 2A. A hollow disposable suction tube 70 is connected to elongated spine 72 and is in fluid communication with hollow connector or receiving member 56. The spine has a pair of cylindrical shaped members 74, 76 having openings 78, 80 formed therein for receiving the tube 70 therein. Further, in the embodiment illustrated in FIG. 2, the suction tube receiving outlet member 56 has an opening 86 located adjacent to the proximal end 54 of the blade for removing noxious fumes, smoke, vaporized tissue, plumes generated by electrocautery and other debris from a patient's mouth during use in surgery. Spine 72 also has a wall 88 extending from end 90 which has an opening 92 therethrough for receiving tube 70. Wall 88 is bent at approximately 90 degrees with respect to spine 72. On a rear side 94 of the spine are formed a plurality of gripping notches or knurl recesses 96 which provide an ergonomic manual grip for the user to grip and hold the spine. Alternatively, referring to FIG. 5, gripping members, protrusions or extensions 98 can be provided to also provide an ergonomic grip.

    [0032] When in use, smoke, plumes generated by electrocautery, noxious fumes and vaporized tissue removal is effectuated by attaching barb or connector 93 (FIG. 3) to a pneumatic device typical of the art which causes a suction effect from the tongue blade.

    [0033] While the surgical application is taking place, the spine 72, which is held in one of the doctor's hands, is held near the patient's mouth directing the suction tube 70 in the patient's mouth and removing smoke, fumes, plumes generated by electrocautery, and vaporized tissue via opening 86. The tongue blade 50, which is connected to the tube, is in the patient's mouth controlling the patient's tongue, thus preventing it from obstructing the application and removing smoke and vaporized tissue at the same time. The tongue blade suction tube 70 meanwhile evacuates the smoke, fumes, plumes generated by electrocautery, and vaporized tissue by sucking it through the receiving port or opening 86, through tube 70, and out through the pneumatic or other suction causing device (not shown) attached to barb 93. After use, the suction tube 70 can be removed and discarded. The spine 72 can be sanitized and reused with a new suction tube.

    [0034] Another variation of the disclosure is a one-piece unit which is fabricated from a high impact plastic that is disposable.

    [0035] FIG. 4 shows an illustration of an alternate embodiment of the disclosure for a one-piece disposable tongue blade and suction device which can be fabricated of thermoplastic or any other suitable material. That is, the device can be used with one patient for a one-time use and then discarded or disposed. The device includes a tongue blade 100 having a distal end 102 for inserting into a patient's mouth during a surgical application and a proximal end 04 coupled in fluid communication with a hollow tube 106 integrally formed with the tongue blade. The tongue blade has a curved or rounded shape body 108 which acts as a tongue depressor and rests on the patient's tongue. The distal end 102 has a fork or U-shaped appearance formed by two protrusions 110, 112 extending therefrom and curved upwardly which form a channel or opening 116 therebetween. The hollow tube 106 extends from an elongated spine 18. The suction tube 106 has an opening 120 located adjacent to the proximal end 104 of the blade for removing noxious fumes, smoke, vaporized tissue, plumes generated by electrocautery and other debris from a patient's mouth during use in surgery.

    [0036] When in use, smoke, plumes generated by electrocautery, noxious fumes and vaporized tissue removal is effectuated by attaching connector end 122 of tube 106 to a pneumatic device typical of the art which causes a suction effect from the tongue blade.

    [0037] While the surgical application is taking place, the spine 118, which is manually held in one of the doctor's hands, is held near the patient's mouth directing the suction tube 106 in the patient's mouth and removing smoke, fumes, plumes generated by electrocautery, and vaporized tissue via opening 120. Meanwhile, the tongue blade 100, which is connected to the tube, is in the patient's mouth controlling the patient's tongue, thus preventing it from obstructing the application and removing smoke and vaporized tissue at the same time. The tongue blade suction tube 106 meanwhile evacuates the smoke, fumes, plumes generated by electrocautery, and vaporized tissue by sucking it through the receiving port or opening 120, through tube 106, and out through any well known device the pneumatic or other suction causing device (not shown), attached to the tube barb 122.
