Abstract
This utility model relates to a kind of anti-slip type disposable endoscope biopsy forceps, comprise binding clip, binding clip frame, bourdon tube, positioning pipe and hands handle, binding clip is connected with the front end of binding clip frame by chain bar, pull bar is set with in bourdon tube, one end of bourdon tube is fixedly connected with the rear end of binding clip frame, the other end is fixedly connected with one end of positioning pipe, the other end of positioning pipe is connected with boost tube and stationary pipes in turn, stationary pipes and handle grafting, binding clip is respectively upper grip head and lower pliers head, the opposite face of upper grip head and lower pliers head there is symmetrical chisel teeth, chisel teeth on upper grip head and lower pliers head is respectively 3 or 4, between adjacent chisel teeth, ending is connected.Anti-slip type disposable endoscope biopsy forceps of the present utility model, by the grade reduction of the profile of tooth by binding clip, the number of teeth also reduces, thus reduce binding clip to sampling disorganization degree, the bending design of binding clip end, not only convenient sampling, and can prevent sampling from dropping.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of anti-slip type disposable endoscope biopsy forceps.
Background technology
The splanchnoscopies such as gastroscope and intestinal mirror due to the pathological changes of gastrointestinal location can be observed intuitively, because of but current clinical conventional detection methods.In endoscopic procedure, doctor is also often by biological tissue sample pickup tongs, first pass through endoscope, biological tissue sample pickup tongs is directly arrived in patient body, employing cuts, clamp and to get or the method such as puncture takes out a certain amount of pathological tissues in patient body, carry out pathological examination, clear and definite histopathologic diagnosis can be made to most censorship case, this inspection method is that inside of human body pathological tissues obtains the most efficient approach of pathological diagnosis most convenient, therefore, biological tissue sample pickup tongs uses widely in clinical endoscopy examination.
But there is following two problems in current conventional biological tissue sample pickup tongs: 1, the contact surface of binding clip and tissue substance is smooth surface, the easy landing when sampling; 2, the serrated surface made of the contact surface of binding clip and tissue substance, easily damages sampling because sawtooth is more, affects the detection to sampling.
Utility model content
The technical problems to be solved in the utility model is: in order to solve deficiency of the prior art, and this utility model provides a kind of anti-slip type disposable endoscope biopsy forceps.
This utility model solves the technical scheme that its technical problem adopts: a kind of anti-slip type disposable endoscope biopsy forceps, comprise binding clip, binding clip frame, bourdon tube, positioning pipe and hands handle, binding clip is connected with the front end of binding clip frame by chain bar, pull bar is set with in bourdon tube, one end of bourdon tube and binding clip frame rear end be fixedly connected with, the other end is fixedly connected with one end of positioning pipe, the other end of positioning pipe is connected with boost tube and stationary pipes in turn, stationary pipes and handle grafting, described binding clip is respectively upper grip head and lower pliers head, the opposite face of upper grip head and lower pliers head there is symmetrical chisel teeth, chisel teeth on upper grip head and lower pliers head is respectively 3 or 4, between adjacent chisel teeth, ending is connected.
During in order to prevent from sampling, sampling body is not easy to cut off or easily drop, the upwards curved bending of described lower pliers head leading section, form arc bending side, offer notch in the middle of arc bending side, the downward curved bending in described upper grip head leading section, kink matches with notch.
Further, particularly, the ramp angle α of chisel teeth is 15 °-20 °.
The beneficial effects of the utility model are, anti-slip type disposable endoscope biopsy forceps of the present utility model, by the grade reduction of the profile of tooth by binding clip, the number of teeth also reduces, thus reduce binding clip to sampling disorganization degree, the bending design of binding clip end, not only convenient sampling, and can prevent sampling from dropping.

In figure: 1, binding clip, 11, upper grip head, 12, lower pliers head, 13, chisel teeth, 14, arc bending side, 15, notch, 16, kink, 2, binding clip frame, 3, bourdon tube, 4, positioning pipe, 5, boost tube, 6, stationary pipes, 7, handle, 8, chain bar, 9, pull bar.
Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with this utility model.
As Figure 1-4, it is embodiment of the present utility model, a kind of anti-slip type disposable endoscope biopsy forceps comprises binding clip 1, binding clip frame 2, bourdon tube 3, positioning pipe 4 and handle 7, binding clip 1 is connected with the front end of binding clip frame 2 by chain bar 8, pull bar 9 is set with in bourdon tube 3, one end of bourdon tube 3 and binding clip frame 2 rear end be fixedly connected with, the other end is fixedly connected with one end of positioning pipe 4, the other end of positioning pipe 4 is connected with boost tube 5 and stationary pipes 6 in turn, stationary pipes 6 and handle 7 grafting, binding clip 1 is respectively upper grip head 11 and lower pliers head 12, the opposite face of upper grip head 11 and lower pliers head 12 there is symmetrical chisel teeth 13, chisel teeth 13 on upper grip head 11 and lower pliers head 12 is respectively 3 or 4, between adjacent chisel teeth 13, ending is connected.The upwards curved bending of lower pliers head 12 leading section, forms arc bending side 14, and offer notch 15 in the middle of arc bending side 14, the downward curved bending in upper grip head 11 leading section, kink 16 matches with notch 15.The ramp angle α of chisel teeth 13 is 15 °-20 °.By the grade reduction of the profile of tooth by binding clip, the number of teeth also reduces, thus reduces binding clip to sampling disorganization degree, the bending design of binding clip end, not only convenient sampling, and can prevent sampling from dropping.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
