Abstract
The invention discloses disposable endoscope biopsy forceps which comprise a forcep head frame, a pull rod, a pull rope, a spring outer pipe, a core rod, a handle, a sliding ring, paired forcep heads and a connecting mechanism which is movably connected with the forcep heads to enable the paired forcep heads to be opened or closed. The pull rope is installed in the spring outer pipe in an inserted mode, one end of the spring outer pipe is connected with the tail end of the forcep head frame in a pressed mode, one end of the pull rod is movably connected with the connecting mechanism, the other end of the pull rod is connected with one end of the pull rope in a pressed mode, and the other end of the pull rope is connected with the sliding ring; the sliding ring is slidably arranged on the core rod in a matched mode, the other end of the spring outer pipe is fixedly connected with one end of the core rod, the other end of the core rod is fixedly connected with the handle, and the paired forcep heads are hinged together and both hinged to the forcep head frame. According to the disposable endoscope biopsy forceps, the phenomenon that the pull rope is broken after the forceps are used for a long time can be avoided, the connecting strength is improved, the service life is prolonged, and the operation sampling effect is guaranteed.
Description
Technical field
The present invention relates to a kind of single use biopsy forceps of endoscope, belong to technical field of medical instruments.
Background technology
At present, splanchnoscopy has been widely used in clinical as a kind of aided diagnosis method, and sample pickup tongs enters gripping diseased region tissue in patient body by endoscope channel, then carries out pathological analysis to make a definite diagnosis disease to the tissue pressed from both sides out.Endoscopic biopsy samples because its wound is little, check the convenient splanchnoscopy means having become routine, biopsy forceps is by push-and-pull slip ring, open or closed process to play binding clip, so the conduction of power is by drag-line and the pull bar etc. being connected to drag-line termination, so pull bar connects the power that drag-line wants stressed more than 60N, tradition by laser weld, pull bar is welded on wirerope, but such welding procedure can cause the hardness of stainless steel material to reduce due to high temperature, show there is little weldering speckle etc., and be easy to fracture, affect surgical effect.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, there is provided a kind of single use biopsy forceps of endoscope, the phenomenon that it can avoid drag-line after a long time use to fracture, improve its bonding strength, improve its service life, ensure the effect of operation sampling.
The present invention solves the problems of the technologies described above the technical scheme taked: a kind of single use biopsy forceps of endoscope, it comprises binding clip frame, pull bar, drag-line, spring outer tube, core bar, hands handle, slip ring and paired binding clip and be flexibly connected with binding clip and paired binding clip opened or closed bindiny mechanism, drag-line is inserted in spring outer tube, one end of spring outer tube and the tail end of binding clip frame are crimped together, one end of pull bar is flexibly connected with bindiny mechanism, the other end of pull bar and one end of drag-line are crimped together, the other end of drag-line is connected with slip ring, slip ring is sliding to be fitted on core bar, the other end of spring outer tube is fixedly connected with one end of core bar, the other end of core bar is fixedly connected with handle, described paired binding clip is hinged, and be all hinged on binding clip frame.
Further provide drag-line and crimp mode so that both connections are more firm with the concrete of pull bar, the crimping position of described drag-line is plugged in the crimping position of pull bar, and compresses the crimping position of drag-line by multiple crimping points of the outer wall at the crimping position of pull bar.
The concrete crimping mode of spring outer tube and binding clip frame that further provides is so that both connections are more firm, the crimping position of described spring outer tube is plugged in the crimping position of binding clip frame, and compresses the crimping position of spring outer tube by multiple crimping points of the outer wall at the crimping position of binding clip frame.
After have employed technique scheme, the present invention is by push-and-pull slip ring on core bar, thus drive drag-line to move relative to spring outer tube, then be driven into right binding clip by bindiny mechanism again open on binding clip frame or close, the connecting portion of drag-line and pull bar and spring outer tube adopt with the connecting portion of binding clip frame and crimp mode, the surface of subduing does not affect technological requirement, simply, fast, environmental protection, energy-conservation, and fastness is more firm, all more than 100N pulling force, even more than 150N, safety coefficient increases greatly, product is protected, the phenomenon that the present invention can avoid drag-line after a long time use to fracture, improve its bonding strength, improve its service life, ensure the effect of operation sampling.
Accompanying drawing explanation
Fig. 1 is the structural representation of single use biopsy forceps of endoscope of the present invention;
Wherein, 1 is binding clip frame; 2 is core bar; 3 is slip ring; 4 is hands handle; 5 is drag-line; 6 is pull bar; 7 is binding clip; 8 is spring outer tube.
Detailed description of the invention
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation.
As shown in Figure 1, a kind of single use biopsy forceps of endoscope, it comprises binding clip frame 1, pull bar 6, drag-line 5, spring outer tube 8, core bar 2, handle 4, slip ring 3 and paired binding clip 7 and be flexibly connected with binding clip 7 and paired binding clip 7 opened or closed bindiny mechanism, drag-line 5 is inserted in spring outer tube 8, one end of spring outer tube 8 and the tail end of binding clip frame 1 are crimped together, one end of pull bar 6 is flexibly connected with bindiny mechanism, the other end of pull bar 6 and one end of drag-line 5 are crimped together, the other end of drag-line 5 is connected with slip ring 3, slip ring 3 is sliding to be fitted on core bar 2, the other end of spring outer tube 8 is fixedly connected with one end of core bar 2, the other end of core bar 2 is fixedly connected with handle 4, paired binding clip 7 is hinged, and be all hinged on binding clip frame 1.
The crimping position of drag-line 5 is plugged in the crimping position of pull bar 6, and compresses the crimping position of drag-line 5 by multiple crimping points of the outer wall at the crimping position of pull bar 6.
