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.
