Description

A kind of rotatable net type foreign body forceps

Technical field

This utility model relates to a kind of medical apparatus and instruments, especially a kind of rotatable net type foreign body forceps.

Background technology

At present, net type foreign body forceps is mainly used in the taking-up to the polyp after being cut into or other foreign bodies under scope.In Clinical practice process, need to adjust string bag direction according to lesions position, realized by the direction rotating the string bag, the common net type foreign body forceps used clinically at present, during rotation, head is beated, rotation has some setbacks, and be difficult to the requirement reaching the even smooth and easy rotation string bag of energy, main cause is that common Cable cannot meet the demands.

The patent No. 201320511450.8 discloses a kind of easily rotation net type foreign body forceps, comprise the string bag, drag-line, outer tube, turncap, guide pipe, slip ring and handle, drag-line plug-in mounting within the outer tube, described drag-line comprises flexible steel cable and titanium-nickel wire, one end of flexible steel cable is fixedly connected with the tail end of the string bag, the other end is fixedly connected with one end of titanium-nickel wire, and the other end of titanium-nickel wire is fixedly connected with the head end of guide pipe.More difficult owing to restoring to the original state after stainless steel silk rotation, so when operating, having and rotating situation generation not in place, and then affecting therapeutic effect.

Utility model content

The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of rotatory better rotatable net type foreign body forceps.

This utility model solves the technical scheme that its technical problem adopts: a kind of rotatable net type foreign body forceps, comprise net type binding clip, interior pipe, core bar and slip ring, described slip ring is arranged on core bar, and along its axial slip, be set with outer tube outside described interior pipe, described outer tube is connected and fixed by turncap and core bar, the tail end of described net type binding clip is connected with titanium-nickel wire by butt tube, described titanium-nickel wire is arranged in interior pipe, and interior pipe is promoted by slip ring, treats to stretch out outer tube.

Further, the upper and lower end of described slip ring and the rear end of core bar are equipped with the finger-hole for finger manipulation.

The beneficial effects of the utility model are: use whole titanium-nickel wire to replace rustless steel steel wire rope, rotatory is better; Use interior pipe, reduce handle diastema, operating handle is better.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, this utility model is further illustrated.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the amplification assumption diagram at A place in Fig. 1.

In figure: 1. net type binding clip, 2. butt tube, 3. titanium-nickel wire, pipe 4., 5. outer tube, 6. turncap, 7. finger-hole, 8. slip ring, 9. core 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 shown in Fig. 1 ~ Fig. 2, a kind of rotatable net type foreign body forceps, comprise net type binding clip 1, interior pipe 4, core bar 9 and slip ring 8, slip ring 8 is arranged on core bar 9, and along its axial slip, outer tube 5 is set with outside interior pipe 4, outer tube 5 is connected and fixed by turncap 6 and core bar 9, and the tail end of net type binding clip 1 is connected with titanium-nickel wire 3 by butt tube 2, and titanium-nickel wire 3 is arranged in interior pipe 4, interior pipe 4 is promoted by slip ring 8, treats to stretch out outer tube 5.

As shown in Fig. 1 ~ Fig. 2, the upper and lower end of slip ring 8 and the rear end of core bar 9 are equipped with the finger-hole 7 for finger manipulation.

During use, the finger of operator stretches into finger-hole 7 and handles slip ring 8 and release net type binding clip 1 forward, when needs net type binding clip 1 direction, fixing turncap 6 on the other hand, rotate core bar 9 on the other hand, now core bar 9 drives titanium-nickel wire 3, drive net type binding clip 1 to rotate simultaneously, reach the requirement of use, the design uses whole titanium-nickel wire to replace rustless steel steel wire rope, and rotatory is better; Use interior pipe, reduce handle diastema, operating handle is better.Net type binding clip 1 of the present utility model has better rotatory, rotates even, facilitates clinical operation to operate.

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.
