Abstract

The invention provides a forceps head module of biopsy forceps with a needle. The forceps head module of the biopsy forceps with the needle comprises a forceps head frame (2), an upper forceps head (4) and a lower forceps head (1) and also comprises a rivet (3) with a needle (3-1), wherein the needle (3-1) is integrally made together with the rivet (3) main body and vertical to a central line of the rivet (3) main body; the upper forceps head (4) and the lower forceps head (1) are both hinged on the rivet (3) main body; and the two ends of the rivet (3) main body are fixedly connected with the forceps head frame (2). According to the invention, the needle is very firmly fixed without being fixed by other fixing methods; the advantages of simple structure, convenience in machining, benefit of reducing cost and convenience in operation are obtained; meanwhile, the appearance and performance of the biopsy forceps can be also improved.

Description

The binding clip assembly that the pin biopsy forceps is arranged

Technical field

The present invention relates to a kind of binding clip assembly that the pin biopsy forceps is arranged, belong to medical instruments field.

Background technology

In recent years at present, in clinical medicine was checked, splanchnoscopy had obtained extensive use as a kind of aided diagnosis method.When certain diseased region was checked in to the patient body, biopsy forceps can stretch in the body by the speculum forceps road, the gripping pathological tissues.By endoscope's sampling, Wicresoft hinders, misery is little, so splanchnoscopy is a kind of well received diagnostic method.

Accurate location when having the pin biopsy forceps to be mainly used in living body sampling makes things convenient for doctor's sampling operation.Existing biopsy forceps with needle mainly is the structure that adopts pin and rivet to separate, pin can rotate on rivet, in order to allow pin fix, need to adopt other fixed form, it is fixing unreliable to exist, the manufacturing procedure complexity, and to additionally abdicate the space for the part of locking pin, had influence on the outward appearance and the performance of biopsy forceps.

Summary of the invention

Purpose of the present invention provides a kind of pin the fixing reliable and easy to operate binding clip assembly that the pin biopsy forceps is arranged.

The technical scheme that realizes above-mentioned purpose is: a kind of binding clip assembly that the pin biopsy forceps is arranged, comprise binding clip frame, upper grip head and lower pliers head, the rivet that also comprises a band pin, pin and rivet body are made one, and pin is vertical with the centrage of rivet body, upper grip head and lower pliers head all are hinged on the rivet body, fixedly connected with the binding clip frame in the two ends of rivet body.

After adopting technique scheme, upper grip head and lower pliers head are hinged on the rivet, fixedly connected with the binding clip frame in the two ends of rivet body, and pin and rivet body are made one, pin can not rotate on rivet, has fixed pin in the time of fixing rivet yet, so pin is fixing very reliable, need not to adopt again other fixed form to fix pin, not only simple in structure, easy to process, help reducing cost, and be convenient to operation, can also improve the outward appearance and the performance of biopsy forceps simultaneously.

The specific embodiment

The present invention is further detailed explanation below in conjunction with drawings and Examples.

Shown in Fig. 1 ~ 7, a kind of binding clip assembly that the pin biopsy forceps is arranged, comprise binding clip frame 2, upper grip head 4 and lower pliers head 1, the rivet 3 that also comprises a band pin 3-1, pin 3-1 and rivet 3 bodies are made one, and pin 3-1 is vertical with the centrage of rivet 3 bodies, and upper grip head 4 and lower pliers head 3 all are hinged on rivet 3 bodies, fixedlys connected with binding clip frame 2 in the two ends of rivet 3 bodies.

Installation method of the present invention is as follows:

Earlier upper grip head 4 and lower pliers head 1 are hinged on the body of the rivet 3 of being with pin 3-1, fixedlyed connected with binding clip frame 2 in the two ends of rivet 3 then, and assemble other parts of biopsy forceps on this basis, after assembling is finished, with laser welding process, riveted joint or other technology, will be with pin rivet 3 to fixedly connected with binding clip frame 2.Finish the installation process of entire belt pin rivet 3.

Rivet 3 is to make of technologies such as powder injection-molded, punching press or machine cut processing, directly has the shape of pin above the rivet.

Claims

1. binding clip assembly that the pin biopsy forceps is arranged, comprise binding clip frame (2), upper grip head (4) and lower pliers head (1), it is characterized in that: the rivet (3) that also comprises a band pin (3-1), pin (3-1) is made one with rivet (3) body, and pin (3-1) is vertical with the centrage of rivet (3) body, upper grip head (4) and lower pliers head (3) all are hinged on rivet (3) body, fixedly connected with binding clip frame (2) in the two ends of rivet (3) body.
