Tubular device for endoscope-assistant surgeryTechnical field
The present invention relates to a kind of tubular devices for endoscope-assistant surgery, belong to the field of medical instrument technology.
Background technique
Endoscope-assistant surgery is equipped using modern photography technology and high-tech surgical instrument, completed under miniature incision thoracic cavity orThe minimally invasive new technology of intraperitoneal complicated operation.
Endoscope-assistant surgery only needs to do the notch of 1~3 1.5cm.One is only needed as the development of clinical treatment technical level is existingEndoscope-assistant surgery can be completed in notch.Intracavitary situation is projected big display screen by small medical camera.Surgical field of viewIt can amplify as needed, show subtle structure, it is apparent more flexible under being looked at straight than naked eyes.Therefore the exposure of surgical field of view,The showing of lesion fine structure, the judgement of Operative Range and safety are better than common open chest surgery.But at present clinically oftenSurgical instrument is when doing endoscope-assistant surgery since notch is smaller, and the angle of opening and closing is too big right in surgical instrument use processNotch causes a degree of expansion to be unfavorable for patient's recovery.
Summary of the invention
The purpose of the present invention is to solve surgical instrument jaws used in existing endoscope-assistant surgery and handle junction pipeDiameter it is larger and using when activity point of view is excessive is easy the problem of causing secondary injury to notch, it is simple to provide a kind of structure, ifCount the compact tubular device for endoscope-assistant surgery.
The present invention adopts the following technical scheme: a kind of tubular device for endoscope-assistant surgery, including jaw and handle, it is describedIt is provided between jaw and handle and bar is straightened, the bar that is straightened is hollow tubular, and described be straightened in bar is provided with traction steel wire, instituteStating jaw includes upper jaw and lower jaw, and the lower jaw is fixed on one end that bar is straightened, and the upper jaw is movably connected in drawingOn straight-bar, one end of the traction steel wire is connected with handle, and the other end of the traction steel wire is connected with upper jaw, and leadsDraw steel wire and is able to drive upper jaw with respect to lower jaw work opening or closing motion.
Further, the caliber that bar is straightened is 4~5mm.
Further, the angle that the upper jaw and lower jaw open is 15~60 °.
Further, the length of the tubular device is 300~550mm.
Further, the handle is set as referring to ring type, and forniciform finger circle hook is provided with above the handle.
Further, the tubular device is made of medical stainless steel or titanium alloy material.
The configuration of the present invention is simple, it is ingenious in design, it is easy to use, using be straightened in bar traction steel wire band movable clamp port open orClosure and it can efficiently adjust very much jaw to proper angle to avoid tubular device other position activity point of view excessive to cuttingMouth causes secondary injury, and the caliber that bar is straightened is smaller, and the puncture outfit that can smoothly pass in and out 5mm carries out pneumoperitoneum operation, refers to circle hookSetting is so that handle more labor-saving and balance when opening more preferably is more suitable for thoracoscope and laparoscopic surgery.
