Biopsy forceps

Abstract

The invention relates to biopsy forceps. The biopsy forceps comprise a handle, sliding handles, a drag line, an insulating sleeve and a drag line rotating device. The sliding sleeves are slidably connected with the handle. One end of the drag line is fixedly connected to the sliding handles. A sling is arranged at the other end of the drag line. The insulating sleeve, namely a hollow sleeve, sleeves the drag line. One end of the insulating sleeve is connected with the handle fixedly. The drag line is divided into two sections, one section is a fixing section fixedly connected with the slidinghandles, and the other section is a rotatable rotating section. The drag line rotating device comprises a shell and a rotating shaft for allowing the rotating section to pass through. The rotating shaft is connected with the shell rotationally. The rotating section of the drag line and the rotating shaft rotate synchronously. The biopsy forceps have the advantages that the sling at the end of thedrag line can rotate at 360 degrees optionally, so that the sling can get in easily from the angle of a lesion tissue during acquiring the lesion tissue, labor and time are saved during acquisition, and operation is simple.

Description

technical field [0001] The invention relates to a drilling tool, in particular to a biopsy forceps. Background technique [0002] Biopsy forceps can enter the patient's body through the endoscope, check the disease in the body, clamp the diseased tissue, and provide pathological basis for diagnosis. There are two types of traditional biopsy forceps, one is the scissor-shaped gripping type at the end, which generally drives the scissor-like gripper to grip the lesion tissue through the booster mechanism, and the scissor-like gripper can be 360° However, the booster mechanism is generally in the shape of a metal tube that cannot be deformed, and the shape cannot be changed at will according to the human body structure, and it is difficult to adjust when it is inserted into the human body; moreover, the structure of this kind of biopsy forceps is complex and the cost is relatively high. There is also a kind of soft lasso, the cost is relatively low, because it adopts soft stee...

Problems solved by technology

There are two types of traditional biopsy forceps, one is the scissor-shaped gripping type at the end, this type generally drives the scissor-like gripper to grip the lesion tissue through the booster mechanism, and the scissor-like gripper can be 360° It can be rotated at will, but the booster mechanism is generally in the form of a metal tube that cannot be deformed, and the shape cannot be changed at will according to the human body structure.

There is also a kind of soft lasso, the cost is relatively low, because it adopts soft steel wire, and the outer tube is also an insulating hose, so it can be inserted into the human body at will, and changes such as bending are performed, but the disadvantage of this biopsy forceps is that due to The head is a lasso structure, and the lasso cannot rotate 360° at will. It is very difficult for the operator to wrap the lasso around the diseased tissue, and the efficiency is very low
