Description
Technical field
This utility model relates to medical examination technical field of surgical instruments, especially a kind of disposable endoscope biopsy forceps of convenient operation.
Background technology
At present, splanchnoscopy has been widely used in clinical as a kind of aided diagnosis method.In splanchnoscopy, sample pickup tongs is an indispensable instrument, and when doctor or patient wish to carry out pathologic finding to diseased region, it can enter in patient body with endoscope channel, the tissue of gripping diseased region, for pathologic finding to make a definite diagnosis.By endoscope's sampling painful little, wound is little, therefore the dark welcome by doctor and patient.
Most sample pickup tongs of present practicality generally by binding clip assembly, elongated driving wire, be sleeved on elastic outer pipe outside driving wire and handle forms, one end of driving wire is connected with the double leval jib skip bucket in binding clip assembly, the other end is connected with the movable bracelet on handle, one end of elastic outer pipe is connected with binding clip assembly, and the other end is connected with handle.Sliding active bracelet drives driving wire, and driving wire drives quadric chain action, and quadric chain drives the left and right binding clip of assembly of taking the lead to realize folding, thus suspect tissue is taken out external.This structure is by sliding active bracelet, and need larger strength, and the range of movement of movable bracelet is limited, jaw subtended angle is less, causes examining the amount of living lower.
Utility model content
The technical problems to be solved in the utility model is: cause examining the problem that the amount of living is low in order to the jaw subtended angle solving existing disposable endoscope sample pickup tongs is little, provides that a kind of jaw subtended angle is large, the disposable endoscope biopsy forceps of labour-saving convenient operation.
This utility model solves the technical scheme that its technical problem adopts: a kind of disposable endoscope biopsy forceps of convenient operation, comprise elastic outer pipe, driving wire and binding clip assembly, described binding clip assembly comprises left binding clip, right binding clip, left connecting rod, right connecting rod, binding clip seat and draw back plate, described left binding clip and right binding clip pass through hinge, rear end and right connecting rod one end of described left binding clip are hinged, rear end and left connecting rod one end of described right binding clip are hinged, described bearing pin is fixed on binding clip seat, the other end of described left connecting rod and the other end of right connecting rod hinged with draw back plate front end respectively, described draw back plate rear end is connected with driving wire front end, also comprise left handle, right handle, tooth bar and connecting plate, the front end of described left handle and right handle is provided with semi-circle gear, described tooth bar both sides are provided with tooth, described left handle and right handle symmetry are arranged on tooth bar both sides, the semi-circle gear of left handle and right handle is meshed with the tooth of the tooth bar left and right sides respectively, described left handle and right handle are hinged with connecting plate respectively, the front end connection for transmission silk of described tooth bar, described elastic outer pipe one end and connecting plate are fixed, the other end and binding clip seat are fixed, to hold with a firm grip left handle and right handle simultaneously, semi-circle gear is rotated, the tooth bar be engaged with moves, drive driving wire and move with draw back plate, thus make left connecting rod and right connecting rod action, control left binding clip and right binding clip folding, gripping pathological tissues.
Further, the mutual occlusal edge of described left binding clip and right binding clip is provided with equally distributed Mus tooth, and Mus land mouth is sharp, makes crawl more firm.
Further, described binding clip seat front end is provided with the pin that needle point points to left binding clip and right binding clip opening direction, the pathological tissues effectively, be accurately fixedly removed.
Further, in order to make sample pickup tongs appearance neat and artistic, described driving wire is arranged in described elastic outer pipe.
The beneficial effects of the utility model are, to hold with a firm grip left handle and right handle simultaneously, semi-circle gear is rotated, by rack and pinion drive mechanism, tooth bar is moved, drive driving wire and move with draw back plate, thus make left connecting rod and right connecting rod action, control left binding clip and right binding clip folding, tooth bar moving range is large, jaw subtended angle is large, be convenient to improve inspection amount alive, structure is simple, convenient and strength-saving.
