[0038] Such as figure 1 As shown, the needle-free biopsy forceps with an integrated forceps head includes an integrated forceps head 1, a flat head pull rod pin 2, a pull rod tube 3, a pull rod positioning block 4 and a forceps head seat 10, wherein the integrated forceps head 1, a flat head pull rod The pin 2 and the pull rod tube 3 form the clamp head set, and the clamp head set, the clamp head seat 10, and the pull rod positioning block 4 are assembled to form the clamp head assembly.

[0039] Specifically, the structure of the integrated pliers head 1 is as follows: Figure 5A and 5B As shown, it includes an integrally formed left pliers head 1a, a right pliers head 1b and a handle 1c for connecting the left pliers head 1a and the right pliers head 1b. The one-piece pliers head is integrally formed from stainless steel through a stamping process. The pliers handle 1c is folded in half, and a central hole 1d is arranged in the middle of the pliers handle 1c (see Figure...

[0049] Such as figure 2 As shown, the needle biopsy forceps with an integrated forceps head includes an integrated forceps head 1, a needle point pull rod pin 5, a pull rod tube 3, a pull rod positioning block 4 and a forceps head seat 10, wherein the integrated forceps head 1, a needle point pull rod The pin 5 and the pull rod tube 3 form the clamp head set, and the clamp head set, the clamp head seat 10, and the pull rod positioning block 4 are assembled to form the clamp head assembly.

[0050] Wherein, in the forceps head set, except that the needle-tip pull-rod pin 5 is different from the flat-head pull-rod pin 2 used in the first embodiment, the rest of the structure is the same as that of the needle-free biopsy forceps provided in the first embodiment. In the needle biopsy forceps provided in this embodiment, as Figure 7 The illustrated needle point pull rod pin 5 is a pull rod pin having a sampling needle portion 5a at the front end, and a protrusion 5c protruding o...

[0056] The structures of the two biopsy forceps are described in detail above, and the corresponding manufacturing methods are introduced below.

[0057] The present invention also provides a manufacturing method for a biopsy forceps with an integrated pliers head, comprising the following steps: manufacturing the integrated pliers head; assembling the integrated pliers head, a pull rod pin, and a pull rod tube into a pliers set; The head seat and the pull rod positioning block are assembled into a clamp head assembly; and the clamp head assembly, drag wire, spring tube, and control handle are assembled into a biopsy forceps. Wherein, the material used for the entire forceps head assembly may be stainless steel materials that meet medical standards, for example, 2Cr13, 3Cr13 and other materials that meet the standards for biopsy forceps.

[0058] Specifically, firstly, the one-piece pliers head 1 is manufactured by a stamping process.

[0059] The manufacturing steps of the i...

Abstract

The invention discloses biopsy forceps with an integrated forceps head and a manufacturing method thereof. The integrated forceps head comprises a left forceps head, a right forceps head and a forcepshandle used for connecting the left forceps head and the right forceps head which are integrally formed, wherein the forceps handle is arranged in a folded mode, and the middle part of the forceps handle is provided with a central hole; the left forceps head and right forceps head which are arranged at the two ends of the forceps handle have elasticity and are shaped into an initial open state, wherein the opening directions are opposite. The integrated forceps head, a pull rod pin and a pull rod tube are assembled into a forceps head kit; the forceps head kit, a pull rod positioning block and a forceps head seat are assembled to forma forceps head assembly, the forceps head assembly,a pull cable, a spring tube and a control handle are assembled into whole biopsy forceps; the structure and assembly process of the biopsy forceps are simplified.

Description

technical field [0001] The invention relates to a biopsy forceps, in particular to a biopsy forceps with an integrated forceps head, and to a manufacturing method of the biopsy forceps. Background technique [0002] Biopsy forceps is a tool used to bite and sample the lesions in the abdominal cavity of the human body, and is generally used in conjunction with an endoscope. In the endoscopic examination, when pathological examination of the lesion is required, the biopsy forceps are sent into the patient's body through the endoscopic forceps channel, and the tissue of the lesion is clamped. Sampling through biopsy forceps is less painful and traumatic, so it is very popular among doctors and patients. [0003] Biopsy forceps are generally composed of a clamp head assembly, a slender cable, a spring tube that is also slender and covered outside the cable, and a handle. One end of the cable is connected to the four-bar linkage mechanism in the clamp head assembly, and the othe...
