Description
Technical field
This utility model relates to a kind of medical examination operating theater instruments, especially a kind of a kind of sample pickup tongs of taking a sample with the supporting use of endoscope, specifically the binding clip assembly of four connecting rod endoscope living body sample pickup tongs.
Background technology
At present, splanchnoscopy has been widely used in clinical as a kind of aided diagnosis method.In splanchnoscopy, sample pickup tongs is the instrument of an indispensability, and when doctor or patient wished that diseased region carried out pathologic finding, it can enter in the patient body by the speculum forceps road, the tissue of gripping diseased region, for pathologic finding so that make a definite diagnosis.By endoscope sampling painful little, wound is little, so be subjected to doctor and patient's welcome deeply.
Now the most sample pickup tongs that use generally are made up of binding clip assembly, elongated drag-line, the elastic outer pipe and the handle that are enclosed within the drag-line outside.
The binding clip assembly comprises that quadric chain and binding clip seat 8, the pull bar 9 be made up of left binding clip 1, right connecting rod 5, right binding clip 2, left connecting rod 4 constitute.The front end of binding clip seat 8 is connected with bearing pin 6; Left side binding clip 1,2 one-tenth X-types of right binding clip are rotationally connected with on the bearing pin 6; Can be arranged in the binding clip seat 8 along binding clip seat 8 axially movable pull bars 9, its rear end links to each other with a end of drag-line 11 in stretching into binding clip seat 8; The front end of left side connecting rod 4 and the rear end of right binding clip 2 are rotationally connected; The rear end of the front end of right connecting rod 5 and left binding clip 1 is rotationally connected; The rear end of rear end, the right connecting rod 5 of left side connecting rod 4 all is rotationally connected with the front end of pull bar 9.
Spring outer tube 12 links to each other handle with binding clip seat 8; Drag-line 11 passes elastic outer pipe 12, and the one end links to each other with pull bar 9, and the other end links to each other with movable bracelet on the handle.
Push away, draw movable bracelet to drive drag-line, drag-line drives the quadric chain action by pull bar, makes two symmetric left and right sides binding clips of binding clip assembly realize opening and closing, thereby takes out external by gastroscope pincers road suspect tissue.
Because in the binding clip assembly of existing four connecting rod endoscope living body sample pickup tongs, the front end of left side connecting rod 4 and the rear end of right binding clip 2, the rear end of the front end of right connecting rod 5 and left binding clip 1, the rear end of left side connecting rod 4, the rear end of right connecting rod 5 all is connected by independent rivet respectively with between the front end of pull bar 9, the riveted poor quality or through after repeatedly using, this sample pickup tongs has so a kind of risk in clinical: rivet may in use come off, make the binding clip can't normally closed and can't take a sample, the rivet that comes off can fall in the patient body as foreign body and might damage the pincers road of endoscope.
Summary of the invention
This utility model solves is the caducous problem of rivet in the binding clip assembly of existing four connecting rod endoscope living body sample pickup tongs.
Binding clip assembly of the present utility model comprises left binding clip 1, right binding clip 2, binding clip seat 8, left connecting rod 4, right connecting rod 5, pull bar 9, and the front end of binding clip seat 8 is connected with bearing pin 6; Left side binding clip 1,2 one-tenth X-types of right binding clip are rotationally connected with on the bearing pin 6; Can be arranged in the binding clip seat 8 along binding clip seat 8 axially movable pull bars 9, its rear end links to each other with a end of drag-line 11 in stretching into binding clip seat 8; The front end of left side connecting rod 4 is rotationally connected by the rear end of bearing pin 13 with right binding clip 2; The front end of right connecting rod 5 is rotationally connected by the rear end of bearing pin 14 with left binding clip 1; The rear end of rear end, the right connecting rod 5 of left side connecting rod 4 all is rotationally connected with the front end of pull bar 9; Left side connecting rod 4, bearing pin 13 are an integral body; Right connecting rod 5, bearing pin 14 are an integral body.
Owing to adopted the bearing pin 13 in aggregates, replaced existing rivet, avoided rivet to come off falling in the patient body, made the binding clip can't normally closed phenomenon with right connecting rod 5 bearing pin 14 in aggregates with left connecting rod 4.
As further improvement, the rear end of the rear end of left connecting rod 4, right connecting rod 5 all is rotationally connected by the front end of bearing pin 15 with pull bar 9; Pull bar 9, bearing pin 15 are an integral body.
Improve as another kind, extend to pin 3 between left binding clip 1, the right binding clip 2 being fixedly connected with on the bearing pin 6 along the axis forward end of binding clip seat 8, perhaps, extend to pin 3 between left binding clip 1, the right binding clip 2 being set with on the bearing pin 6 along the axis forward end of binding clip seat 8, binding clip seat 8 is provided with and is used to the bearing pin 7 that prevents that pin 3 from rotating around bearing pin 6.
After adopting above-mentioned pin 3, when sampling, pin 3 can thrust the pathological tissues that there is hard projection tissue on the surface, prevent that sample pickup tongs from sliding, so just can take a sample smoothly, and improve the sampling accuracy rate, overcome not with the sample pickup tongs of pin when the sampling easily because of partly tissue of pathological changes can not Fu be got in slip, sampling is inaccurate or sampling amount is not enough.
The beneficial effects of the utility model;
1, solved the rivet obscission that existing four common connecting rod sample pickup tongs in use are prone to.
2, it is inaccurate or sampling amount is not enough or get the risk that causes mistaken diagnosis less than sample to have solved sampling that the pathological tissues rat brings.
3, structure is simpler, and is easily manufactured.
