Abstract
A kind of biopsy forceps of endoscope, comprise binding clip assembly, Handleset, spring outer tube (4) and drag-line (5), binding clip assembly is by binding clip (1), binding clip frame (2) and pull bar (3) composition, Handleset is by slip ring (7), core bar (6), form with bracelet (8), drag-line (5) is positioned at spring outer tube (4), binding clip (1) in binding clip assembly and binding clip frame (2) are riveted, one end of spring outer tube (4) is connected with binding clip frame (2), the other end is connected with core bar (6), one end of drag-line (5) is connected with pull bar tail end, the other end is connected with slip ring (7), it is characterized in that: pull bar (3) head end for Z-shaped bending structure, and the head end of pull bar (3) is connected with binding clip uropore.This utility model has the advantage that Product Safety is high, process structure is simple, bonding strength is high, cost is low.
Description
Technical field
This utility model relates to a kind of biopsy forceps of endoscope, belongs to medical instruments field.For the living body sampling of Microendoscopic.
Background technology
At present, splanchnoscopy has been widely used in clinical as a kind of aided diagnosis method.Sample pickup tongs enters gripping diseased region tissue in patient body by speculum forceps, 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, and it is convenient to check, has become conventional splanchnoscopy means.
Most sample pickup tongs of present use form primarily of binding clip assembly, drag-line, spring outer tube and handle.Different by syndeton, binding clip assembly can be divided into coupling type, link-type two kinds:
1, coupling type, adopt steel wire be bent into cast be inserted in pincers in uropore then to circle bending place carry out laser weld.The shortcoming of this mode is, hook steel wire diameter is many within 0.3mm, and more than the 2000 DEG C TRANSIENT HIGH TEMPERATURE that laser weld produces can draw the annealing of hook steel wire weld adjacent material, thus have impact on the bonding strength of product, reduces the safety that product uses.
2, link-type, adopt metal link rod and binding clip afterbody hinged.The shortcoming of this mode is, complex process, and cost is higher, is unfavorable for batch production.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides the biopsy forceps of endoscope that a kind of Product Safety is high, process structure is simple, bonding strength is high, cost is low.
The technical solution of the utility model is: a kind of biopsy forceps of endoscope, comprise binding clip assembly, Handleset, spring outer tube and drag-line, binding clip assembly is by binding clip, binding clip frame and pull bar composition, Handleset is by slip ring, core bar, form with bracelet, drag-line is positioned at spring outer tube, binding clip in binding clip assembly and binding clip frame are riveted, one end of spring outer tube is connected with binding clip frame, the other end is connected with core bar, one end of drag-line is connected with pull bar tail end, the other end is connected with slip ring, it is characterized in that: pull bar head end is Z-shaped bending structure, and the head end of pull bar is connected with binding clip uropore.
Further, pull bar adopts rustless steel steel wire to make.
After have employed technique scheme, at the pull bar head end through binding clip uropore, there is a Z-shaped bending, Z-shaped bending is mounted in binding clip uropore, Z-shaped bending interlude is axially flexibly connected with being formed between binding clip uropore, and Z-shaped bending head end makes diameter become greatly and be greater than binding clip uropore because of bending, therefore pull bar can not come off, bonding strength is higher than cast pull bar, ensure that the safety that product uses, and compared to bar linkage structure product simplification technique, reduce production cost.

Detailed description of the invention
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, this utility model is described in further detail,
As shown in Figure 1, a kind of biopsy forceps of endoscope, comprise binding clip assembly, Handleset, spring outer tube 4 and drag-line 5, binding clip assembly is by binding clip 1, binding clip frame 2 and pull bar 3 form, Handleset is by slip ring 7, core bar 6, form with bracelet 8, drag-line 5 is positioned at spring outer tube 4, binding clip 1 in binding clip assembly is riveted with binding clip frame 2, one end of spring outer tube 4 is connected with binding clip frame 2, the other end is connected with core bar 6, one end of drag-line 5 is connected with pull bar tail end, the other end is connected with slip ring 7, pull bar 3 head end is Z-shaped bending structure, and the head end of pull bar 3 is connected with binding clip uropore.Z-shaped bending is mounted in binding clip uropore, Z-shaped bending interlude is axially flexibly connected with being formed between binding clip uropore, Z-shaped bending head end makes diameter become large and be greater than binding clip uropore because of bending, therefore pull bar can not come off, bonding strength is higher than cast pull bar, ensure that the safety that product uses, and compared to bar linkage structure product simplification technique, reduce production cost.Pull bar 3 adopts rustless steel steel wire to make.Adopt stainless steel silk making pull bar 3 can guarantee the intensity of pull bar, and can not get rusty in surface, aesthetics is good.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
