Pair of biopsy forceps based on swing rod mechanism

Abstract

The invention discloses a pair of biopsy forceps based on a swing rod mechanism. The biopsy forceps comprises a handle assembly, a transmission assembly, a forceps head assembly and a traction steel wire; the handle assembly comprises a finger ring, a cylindrical guide rail, an upper handle, a lower handle, a sliding ring, an outer gear shaft and an inner gear shaft, and the transmission assemblycomprises a spring tube, a primary plane swing rod mechanism, a push rod and a fixing rod; the first-level plane swing rod mechanism comprises a first driving rod, a second driving rod, a third driving rod, a fourth driving rod, a fifth driving rod and a swing rod. The biopsy forceps can achieve rotation and swing of the forceps head of the biopsy forceps, and medical staff can conveniently hold the biopsy forceps due to the fact that the handles are installed. Opening and closing movement and swing of the pliers can be controlled by controlling the handles to move, and the inner gear and theouter gear can be completely meshed by controlling rotation of the pull rings so as to control rotary movement of the pliers.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and more specifically, to a biopsy forceps based on a swing bar mechanism. Background technique [0002] At present, endoscopy has been widely used clinically as an auxiliary diagnostic method. The sampling forceps enter the patient's body through the endoscope forceps to clamp the lesion tissue, and then perform pathological analysis on the clamped tissue to diagnose the disease. The general clinical operation is that, with the aid of the endoscope, the sampling forceps enter the human body through the endoscope forceps, the forceps head is aimed at the lesion, and the handle slider is pushed, the jaws can be opened, and then close to the sampled tissue, Pull the handle slider, the jaws can be closed at this time, pull the outer tube backward, and take out the sampling forceps; in addition, the sampling forceps will also clamp some other medical equipment in and out of the human body d...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that it is difficult to observe the diseased tissue and adjust the temperature of the angle when the traditional biopsy forceps are used. A biopsy forceps based on the swing rod mechanism is proposed, which can hold the handle of the operating handle and adjust the position of the forceps head. Angle, so that the medical staff can hold it conveniently and comfortably, and can also make the pliers head of the sampling forceps reach a suitable angle
