Abstract
The utility model relates to the technical field of biopsy forceps for an endoscope, and in particular to the head part of a pair of biopsy forceps. A left forceps head, a right forceps head, a left connecting rod and a right connecting rod are arranged at the head part; the middle part of the left forceps head is articulated with the middle part of the right forceps head; forceps head rivets are arranged at the tail-ends of the left forceps head and the right forceps head respectively, and the forceps head rivets are integrated with the left forceps head and the right forceps head respectively; corresponding forceps head rivet holes are formed at the head ends of the left connecting rod and the right connecting rod respectively; the left forceps head is in rivet connection with the right connecting rod, and the right forceps head is in rivet connection with the left connecting rod, and the tail-end of the left connecting rod is articulated with the tail-end of the right connecting rod; the walls of the aperture portions of the connecting rods are thickened, so that the forceps are prevented from being damaged in burnishing; and a steel wire cable is utilized for connecting the connecting rods with a steel wire rope, so as to ensure that the strength and the precision of the utility model can both meet the design specifications, and the quality of the utility model is apparently superior to the head part of the prior connecting rod-based biopsy forceps. The utility model solves the technical problems with the head part of the prior connecting rod-based biopsy forceps that, as a result of the poor structural design of the head part, the rivet holes at the tail-ends of the forceps heads are subject to damage or crack in burnishing, and a pull rod can be easily broken into two when being pulled.
Description
Technical field
This utility model relates to the biopsy forceps technical field of using, especially a kind of head of biopsy forceps under endoscope.
Background technology
Biopsy forceps also claims biopsy forceps, and it is the conventional apparatus that the biopsy sampling must be used under endoscope in the hospital clinical.Current, according to related data statistics, annually to use biopsy forceps to carry out the case that biopsy takes a sample to check to reach tens million of, the living body sampling inspection that domestic hospital uses also reaches more than 900 ten thousand cases.Therefore, the quality of biopsy forceps receives much concern, and the part of whole piece biopsy forceps quality most critical is: the head of biopsy forceps.
The structure of biopsy forceps as shown in Figure 1, it has head 1, stainless steel spring flexible pipe 2, plastic handle 3 and the slip ring 4 of biopsy forceps.Under the supervision of endoscope, biopsy forceps enters by endoscope's biopsy channel hole, after accurately locating, the preceding slip ring 4 that pushes away on the plastic handle 3, the opening clamp draught animals, be close to sampled tissue, strain at slip ring backward, binding clip mouth closure is finished sampling, pull back stainless steel spring flexible pipe 2, take out biopsy forceps.
At present, the structure of the head of biopsy forceps has two classes in the world, the first kind: pothook type, second class: link type.The head construction of the biopsy forceps of pothook type is shown in Fig. 2-5: it has left binding clip 1, right binding clip 2 and steel wire connecting rod 6.Now respectively this binding clip of two types is analyzed:
From above analysis, can reach a conclusion: the superior pothook type of the capability and performance of link type structure.
The head construction of the biopsy forceps of existing link type is shown in Fig. 6-11, and it has left binding clip 1, right binding clip 2, the incorporate left connecting rod 3 of rivet, the integrated right connecting rod 4 of rivet and pull bar 5.The head of the biopsy forceps of this link type is with respect to the head of pothook type biopsy forceps, really the product quality aspect there has been improvement clearly, but because very little of the size of biopsy forceps, fit tolerance requires than higher, after connecting rod has rivet, on binding clip, will offer corresponding rivet hole, aperture to rivet hole requires quite high, in the production process, when binding clip and the incorporate binding clip of rivet are polished, be easy to the rivet hole of binding clip end is thrown bad, or the crack of dishing out.Because size is very little, naked eyes are just checked not come out sometimes, product just circulate next procedure, packing warehouse-in at last.Just there has been very big hidden danger in this for product quality.Connecting rod and steel wire rope ways of connecting are by pull bar 5, to this pull bar 5, mainly are to produce by the mode of corrosion resistant plate being carried out the line cutting, assembling then.Intensity and required precision also are difficult to reach fully designing requirement in the process of cutting, and pull bar 5 is broken easily, and there has been very big hidden danger in this equally for product quality.For large usage quantity, being directly used in the biopsy forceps that human body is checked, such hidden danger of quality is not allow.
Summary of the invention
The technical problems to be solved in the utility model is: solve rivet hole that the head of the biopsy forceps of existing link type exists the binding clip end because of the structural design reason and easily throw the technical problem that the bad or crack of dishing out, pull bar are broken easily; This utility model provides a kind of head of biopsy forceps of link type, and it is integrated with rivet and binding clip, and the wall thickness thickening at the position, aperture of connecting rod is difficult for throwing bad during polishing; The employing wire digging line that connecting rod is connected with steel wire rope, its intensity and precision can both reach designing requirement.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of head of biopsy forceps, has left binding clip, right binding clip, left side connecting rod and right connecting rod, left side binding clip and right binding clip are articulated and connected at both middle parts, the head end of left side connecting rod and the end of right binding clip are articulated and connected, the head end of right connecting rod and the end of left binding clip are articulated and connected, left side connecting rod and right connecting rod end are articulated and connected, the end of left side binding clip and right binding clip has respectively and the incorporate binding clip rivet of its binding clip, the head end of left side connecting rod and right connecting rod offers corresponding binding clip rivet hole respectively, rivet in left side binding clip and right connecting rod the binding clip rivet hole and link together by the binding clip rivet insertion right connecting rod of left binding clip, right binding clip and the left connecting rod binding clip rivet by right binding clip inserts to rivet in the binding clip rivet hole of left connecting rod and links together, there is the end of a connecting rod to have and the incorporate connecting rod rivet of connecting rod in left side connecting rod and the right connecting rod, the end of another connecting rod correspondingly offers the connecting rod rivet hole, be set with wire digging line on the connecting rod rivet, the connecting rod rivet inserts in the connecting rod rivet hole and rivets, with left connecting rod, right connecting rod and wire digging line link together.
The beneficial effects of the utility model are, the head of biopsy forceps of the present utility model is integrated with rivet and binding clip, and the wall thickness thickening at the position, aperture of connecting rod is difficult for throwing bad during polishing; The employing wire digging line that connecting rod is connected with steel wire rope, its intensity and precision can both reach designing requirement, and quality obviously is better than the head of the biopsy forceps of existing link type.
