Abstract
This utility model relates to a kind of new disposable biopsy forceps of endoscope, the tooth bar that binding clip assembly comprises binding clip seat, is provided with the left binding clip of semi-circle gear, is provided with the right binding clip of semi-circle gear and engages with left binding clip, right binding clip, left binding clip and right binding clip are symmetrical arranged, tooth bar two sides are equipped with tooth, engage with the semi-circle gear of left binding clip and right binding clip respectively, the semi-circle gear of left binding clip and right binding clip is hinged with binding clip seat respectively, and tooth bar is connected with driving wire; Push-and-pull bracelet makes driving wire action, thus band carry-over bar moves, the left binding clip be meshed with tooth bar and right binding clip reversely rotate, thus realize the opening and closing of jaw, use double-rack-and-pinion drive mechanism to replace quadric chain, the connection rivet having stopped quadric chain sample pickup tongs comes off, and falls into the risk also likely damaging endoscope channel in patient body, structure is simple, and safety is high.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of new disposable biopsy forceps of endoscope.
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 use 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 quadric chain 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.So a kind of risk is there is in common quadric chain sample pickup tongs clinically, namely binding clip is riveted by rivet and connecting rod, rivet may in use come off, make binding clip cannot normally closed and cannot working, the rivet come off to fall in patient body as foreign body and likely damage the pincers road of endoscope.
Utility model content
The technical problems to be solved in the utility model is: the risk that the rivet that in use there is riveted joint binding clip and connecting rod to solve common double leval jib sample pickup tongs comes off, rivet falls into the problem also may damaging endoscope channel in human body, provides a kind of rack and pinion drive mechanism to replace the new disposable biopsy forceps of endoscope of quadric chain.
This utility model solves the technical scheme that its technical problem adopts: a kind of new disposable biopsy forceps of endoscope, comprise binding clip assembly, Handleset, driving wire and elastic outer pipe, described elastic outer pipe one end is connected with Handleset, the other end is connected with binding clip assembly, described driving wire is positioned at elastic outer pipe, described Handleset comprises the hands ring connected successively, slide bar, slip ring and core bar, described bracelet connects slide bar end, described slide bar front end connection slip ring end, described slip ring front end connects core bar end, described driving wire one end connects core bar front end, other end connection clamp head group part, described binding clip assembly comprises binding clip seat, be provided with the left binding clip of semi-circle gear, be provided with semi-circle gear right binding clip and with left binding clip, the tooth bar of right binding clip engagement, described left binding clip and right binding clip are symmetrical arranged, described tooth bar two sides are equipped with tooth, engage with the semi-circle gear of left binding clip and right binding clip respectively, the semi-circle gear of described left binding clip and right binding clip is hinged with binding clip seat respectively, described tooth bar is connected with driving wire.
Further, described binding clip assembly, driving wire and elastic outer pipe material are rustless steel.
During use, push-and-pull bracelet makes driving wire action, thus band carry-over bar moves, and the left binding clip be meshed with tooth bar and right binding clip reversely rotate, thus realize the opening and closing of jaw.
The beneficial effects of the utility model are, push-and-pull bracelet makes driving wire action, thus band carry-over bar moves, the left binding clip be meshed with tooth bar and right binding clip reversely rotate, thus realize the opening and closing of jaw, use double-rack-and-pinion drive mechanism to replace quadric chain, the connection rivet having stopped quadric chain sample pickup tongs comes off, fall into the risk also likely damaging endoscope channel in patient body, structure is simple, and safety is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of binding clip assembly in this utility model.
In figure: 1. binding clip assembly, 11. left binding clips, 12. right binding clips, 13. tooth bars, 14. binding clip seat, 2. driving wire, 3. elastic outer pipe, 4. core bar, 5. slip ring, 6. slide bar, 7. bracelets.
Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with this utility model.
