Abstract
The utility model relates to a gun type negative pressure automatic quick cutter for vocal cord polyps. The utility model is a throat surgical instrument which uses negative pressure air to adsorb lesion tissue, and the blade can be driven by a mechanical driving device to remove the vocal cord polyps swiftly. The utility model is composed of a suction head (14), a long sleeve (16), a fixing pipe (22), a handle (12), and a set of driving devices. The operative procedure of cutting the vocal cord polyps can be accomplished in a twinkle, and simultaneously the operation visual field can be cleared. The utility model causes the operative procedure to become simple, reliable, and safe. The utility model overcomes abuse of the traditional operative method. The operation effect of the utility model is obviously superior to the operation effect of the old-fashioned instrument.
Description
This utility model relates to a kind of medical apparatus and instruments, and particularly a cover is used for the laryngeal surgical instruments of cutting sound bearing interest meat.This is a kind ofly can adsorb polyp of vocal cord automatically, and can finish the novel larynx section surgical medical apparatus of polyp cutting in moment.
At present both at home and abroad department of otorhinolaryngology institute generally the polyp of vocal cord cutting method of employing be traditional pincers and sting division, the operation technique difficulty, the patient has certain misery, surgical effect is not satisfactory.
This utility model utilizes air negative pressure to adsorb polyp of vocal cord automatically, promotes blade under the drive of a cover actuating device fast, finishes the operation technique that cuts polyp in a flash, has removed surgical field of view simultaneously.Make operation technique become very simple, reliable, safe, overcome the drawback of traditional surgical approaches, surgical effect obviously is better than old-fashioned apparatus.
This utility model is made up of suction nozzle (14), long sleeve pipe (16), stationary pipes (22), handle (12) and a cover actuating device.Described suction nozzle (14) is a hollow, one end is that cecum, other end car have female thread, can be connected with long sleeve pipe (16), the suction nozzle side is near the suction nozzle (25) of the You Yi Round of cecum place pass, movable blades (15) is arranged in the suction nozzle (14), movable blades (15) the cut bar (19) interior with being installed in long sleeve pipe (16) links to each other, and cuts the other end cylinder lever connecting rod (20) of bar (19); One end of long sleeve pipe (16) has been installed suction nozzle (14), and the other end is installed on the stationary pipes (22), on long sleeve pipe (16) one side near stationary pipes (22), a trachea spigot joint (17) is arranged; Sealing ring (18), pull bar (20), spring (21) are arranged in the stationary pipes (22), and handle (24) is installed in an end of pull bar (20); Stationary pipes (22) is installed in the top of handle (12), and the plate machine (9) in the handle (12), the cut bar (19), pull bar (20), spring (21) handle (24) that connect in piece (4), stop block (6) plate machine spring (10) and the stationary pipes (22) are formed the actuating device that a cover can drive movable blades (15) motion jointly.
Go up cover one leather hose at trachea spigot joint (17) during operation and connect suction pump, to produce negative pressure.To shake hands (24) outwards pull out, pull bar (20) moves thereupon, and compression spring (21), under the effect of plate machine spring (10), plate machine (9) is ejected handle (12), the company's of drive piece (4) and stop block (6) move up stop block (6) simultaneously, block pull bar (20), it can not be resetted, meanwhile, cut bar (19) drive movable blades (15) and move to suction nozzle (25) top, the cut state of preparing; Detain plate machine (9), by connecting piece (4) stop block (6) is moved down, discharge pull bar (20), compressed spring (21) resets fast, pushing drawing rod (20) drives and cuts bar (19), movable blades (15) is promoted downwards rapidly, and sealing suction nozzle (25) is finished cutting action.
