Abstract
The utility model discloses a pair of four linking rod type endoscope biopsy forceps with four needles, which has the advantages of simple structure and reliability and comprises forceps head assemblies. The forceps head assemblies are mainly composed of a left forceps head (1), a right forceps head (2), a forceps head seat (3), a left connecting rod (4) and a right connecting rod (5). The utility model is characterized in that needles (10) are fixedly arranged between the left forceps head (1) and the right forceps head (2); pins (16) which are used for connecting the left forceps head (1) and the left connecting rod 4, and pins (17) which are used for connecting the right forceps head (2) and the right connecting rod (5) are formed into an integrative body with the corresponding left forceps head (1), and the right forceps head (2).
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 a kind of band pin four link type 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.
The most sample pickup tongs that use generally are made up of binding clip assembly, elongated drag-line, the same elongated elastic outer pipe and the handle that are enclosed within the drag-line outside now, one end of drag-line links to each other with quadric chain in the binding clip assembly, the other end links to each other with movable bracelet on the handle, one end of elastic outer pipe links to each other with the binding clip assembly, and the other end links to each other with handle.Push away, draw movable bracelet to drive drag-line, drag-line drives the quadric chain action, and two symmetrical binding clips that quadric chain drives on the binding clip assembly are realized opening and closing, thereby takes out external by gastroscope pincers road suspect tissue.Because the surface of pathological tissues has hard projection tissue sometimes, common sample pickup tongs can not be got pathological changes tissue or sampling amount deficiency partly by Fu because of slip easily when sampling.In addition, the sample pickup tongs of common quadric chain also has so a kind of risk in clinical, and promptly binding clip binding clip partly links together by rivet and connecting rod.The riveted poor quality or through after repeatedly using, 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
The purpose of this utility model provide a kind of simple in structure, be with pin four link type endoscope living body sample pickup tongs more reliably, with the phenomenon that the rivet that solves pathological tissues sampling difficulty and four-bar linkage structure easily comes off, slides and can not accurately take a sample, avoid operation risk to improve the sampling accuracy rate.
The technical solution of the utility model is:
A kind of band pin four link type endoscope living body sample pickup tongs, comprise the binding clip assembly, the binding clip assembly is mainly by left binding clip 1, right binding clip 2, binding clip seat 3, left side connecting rod 4, right connecting rod 5 is formed, left side binding clip 1, right binding clip 2 is journaled on the bearing pin 6, bearing pin 6 is fixed in the binding clip seat 3, left side connecting rod 4, one end of right connecting rod 5 is riveted on corresponding left binding clip 1, pin 16 on one end of right binding clip 2, in 17, the other end of left side connecting rod 4 and right connecting rod 5 is all riveted by rivet 15 mutually with an end of pull bar 7, the other end of pull bar 7 links to each other with the connection tube 8 that is arranged in binding clip seat 3, connection tube 8 links to each other with an end of drag-line 9, drag-line 9 is positioned among the elastic outer pipe 14, one end of spring outer tube 14 links to each other with binding clip seat 3, the other end of spring outer tube 14 and drag-line 9 all links to each other with handle portion, it is characterized in that at left binding clip 1, be installed with pin 10 between the right binding clip 2; The pin 17 that connects the pin 16 of left binding clip 1 and left connecting rod 4 and be connected right binding clip 2 and right connecting rod 5 is an integral body with corresponding left binding clip 1, right binding clip 2 all.
One end of pin 10 is most advanced and sophisticated, and the other end is an installation end, is provided with two locating holes 11,12 on installation end, and wherein locating hole 11 matches with bearing pin 6, and locating hole 12 matches with another bearing pin 13 on being fixed on binding clip seat 3.
The beneficial effects of the utility model:
1, 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.
2, solved the rivet obscission that existing four connecting rod sample pickup tongs in use are prone to.
3, structure is simpler, and is easily manufactured.
