Abstract

The invention discloses novel negative pressure suction type biopsy forceps, and solves the problems that an existing biopsy forceps occlusion texture is difficult in operation. The novel negative pressure suction type biopsy forceps are characterized in that one end of a suction tube 4 is provided with a sliding handle 5; the middle of the sliding handle 5 is vertically provided with a sliding handle holder 6; the sliding handle holder 6 is in sliding insertion in the suction tube 4; the other end of the suction tube 4 is connected with a biopsy tube 2; the other end of the biopsy tube 2 is connected with a biopsy cap 1; the tip of the biopsy cap 1 is provided with a step type groove 7; the step type groove 7 is provided with a steel wire rope head fixator 8 and a steel wire rope positioning hole 9; one end of a steel wire rope 3 is fixed on the steel wire rope head fixator 8, and the other end of the steel wire rope 3 penetrates through the steel wire rope positioning hole 9, the biopsy cap 1, the biopsy tube 2 and the suction tube 4 to be connected with the sliding handle holder 6; and a steel wire loop 10 is formed in the step type groove 7 of the biopsy cap 1. The novel negative pressure suction type biopsy forceps have the advantages that a biopsy forceps head is small, a target area is not blocked, biopsy can be accurately carried out in a target area, accuracy is high and efficiency is good. The novel negative pressure suction type biopsy forceps are especially suitable for applying to endoscopy and pathological specimen fetching.

Description

Technical field: [0001] The invention belongs to the technical field of medical equipment manufacturing, and in particular relates to a novel negative pressure suction type biopsy forceps. Background technique: [0002] As far as the inventor knows, biopsy forceps are currently an indispensable tool for taking pathological specimens in endoscopic examination. According to the experience of endoscopic examination in recent years, it has been found that the existing commonly used occlusal biopsy forceps blocks part of the field of vision after the tiles are fully opened, resulting in the target The area is partially blocked, and it is impossible to accurately perform biopsy in the target area. The existing biopsy methods require a certain amount of support from the tissue. Only when the biopsy forceps are firmly pressed against the tissue can they bite enough tissue. If it is not supported, the biopsy forceps cannot be firmly pushed against the tissue, and enough tissue cannot...
