Abstract
The utility model relates to a forcep head component for an endoscope biopsy forceps, which comprises a forcep head frame, two steel wires, a left forcep head and a right forcep head, wherein one end of one of the two steel wires is connected with an operating lever; and the left forcep head and the right forcep head are hinged with the forcep head frame; the other end of the steel wire passes through the left forcep head, a ball head which is integrated into a whole with the steel wire is arranged on the steel wire passing through left forcep head, and the diameter thereof is larger than that a hole for the steel wire to pass through on the left forcep head; the other end of the other steel wire passes through the right forcep head, and a ball head which is integrated into a whole with the steel wire is arranged on the steel wire passing through the right forcep head, and the diameter thereof is larger than that a hole for the steel wire to pass through on the right forcep head. The utility model can ensure the reliable connection between the steel wire and the forcep head and convenient manufacture and improve the use safety.
Description
Technical field
This utility model relates to a kind of endoscopic biopsy pincers that are used for living tissue sampling under endoscope's mirror, specifically, relates to a kind of binding clip assembly of endoscopic biopsy pincers.
Background technology
The binding clip assembly of endoscopic biopsy pincers at present commonly used is mainly by the binding clip frame, two steel wires that an end is connected with stick, and left binding clip and the right binding clip composition hinged with the binding clip frame, and the other end of steel wire is connected with left and right binding clip respectively.Main following three kinds of the connected mode of steel wire and left and right binding clip:
1, the steel wire that will pass binding clip is partly pounded flatly, makes steel wire can tangle binding clip.The shortcoming of this connected mode is, the intensity of steel wire of pounding flat part reduces, and pounding flat part may or come off from the steel wire fracture, causes being connected of steel wire and binding clip not firm.
2, the steel wire that will pass binding clip curves " Z " prefix, makes steel wire tangle binding clip.The shortcoming of this structure is, " Z " prefix steel wire has wedge angle, might be when using biopsy forceps the scratch biopsy channel hole.
3, the steel wire that will pass binding clip curves suspension ring, utilizes suspension ring to tangle binding clip, and the opening part of suspension ring is sealed with weld seam.The shortcoming of this structure is a complex process.
Summary of the invention
The purpose of this utility model provides a kind of steel wire is connected firm, easily manufactured endoscopic biopsy pincers with binding clip binding clip assembly.
The technical scheme that realizes above-mentioned purpose is: a kind of binding clip assembly of endoscopic biopsy pincers, comprise the binding clip frame, two steel wires that one end is connected with stick, and left binding clip and the right binding clip hinged with the binding clip frame, the other end of a steel wire passes left binding clip, and passing to have on the steel wire of left binding clip with steel wire be the bulb of one, and the diameter of this bulb is greater than the diameter in the hole that allows steel wire pass on the left binding clip, the other end of another root steel wire passes right binding clip, and passing to have on the steel wire of right binding clip with steel wire be the bulb of one, and the diameter of this bulb is greater than the diameter in the hole that allows steel wire pass on the right binding clip.
After adopting technique scheme, have one on the steel wire of binding clip and make the one bulb with steel wire passing, the diameter of bulb is greater than allowing steel wire pass the hole of binding clip, so bulb can not come off, and it is firm, easily manufactured to guarantee that steel wire is connected with binding clip.Simultaneously, also avoid wedge angle, can eliminate the risk of binding clip scratch biopsy channel hole, improved the safety of using.

Fig. 4 is the connection diagram of this utility model and stick.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in further detail.
Shown in Fig. 1～3, a kind of binding clip assembly of endoscopic biopsy pincers, comprise binding clip frame 1, two steel wires 2 that one end is connected with stick, and left binding clip 3 and the right binding clip 4 hinged with binding clip frame 1, the other end of a steel wire 2 passes left binding clip 3, and to have on the steel wire 2 that passes left binding clip 3 with steel wire be the bulb 5 of one, and the diameter of this bulb 5 is greater than the diameter in the hole that allows steel wire 2 pass on the left binding clip 3, the other end of another root steel wire 2 passes right binding clip 4, and to have on the steel wire 2 that passes right binding clip 4 with steel wire be the bulb 5 of one, and the diameter of this bulb 5 is greater than the diameter in the hole that allows steel wire 2 pass on the right binding clip 4.Stick is made up of handle mobile jib 7, outer tube 6 and slip ring 8, and outer tube 6 is fixedlyed connected with handle mobile jib 7, and outer tube sleeve is on steel wire 2, and slip ring 8 is enclosed within on the handle mobile jib 7 movably, and slip ring 8 is connected with steel wire 2.
Operation principle of the present utility model is as follows: as shown in Figure 4, by the slip ring on the finger push stick 8, transmitted motion on the binding clip by steel wire 2, make left and right binding clip open and close, reach the purpose of use.
