bladder stone forceps

Abstract

The invention discloses bladder lithotomy forceps which comprise an upper forcep body and a lower forcep body structurally symmetric with the upper forcep body. The upper force body comprises an upper forcep handle, an upper forcep rod and an upper forcep head, the upper forcep rod is fixedly connected with the upper forcep handle, is integrally tubular and is hollow, and the upper forcep head is located at a front end opening of the upper forcep rod. The lower forcep body comprises a lower forcep handle, a lower forcep rod and a lower forcep head, the lower forcep rod is fixedly connected with the lower forcep handle, is integrally tubular and is hollow, and the lower forcep head is located at a front end opening of the lower forcep rod. A water inlet is formed in the position, close to the upper forcep handle, of the upper forcep rod, a suction opening is formed in the position, close to the lower forcep handle, of the lower forcep rod, a hollow pin for rotational connection and communicating is arranged between the upper forcep rod and the lower forcep rod, and one end of the hollow pin is located on one side face of the upper forcep body and provided with a pressing valve for opening and closing the hollow pin. According to the bladder lithotomy forceps, multiple functions of the hollow forcep rods are effectively combined, the bladder lithotomy forceps can serve as flushing and suction channel pipes and can also serve as gravel channel pipes for picking fine stone and force arms for picking the stone, and the bladder lithotomy forceps are convenient to use, simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to bladder stone removal forceps. Background technique [0002] Bladder stone removal forceps are a kind of instrument commonly used in the surgical operation of stone removal, in order to grasp stone. Existing bladder stone removal forceps are composed of a handle and a forceps head, which have a simple structure and adopt the principle of mechanical mechanics to capture stones. The forceps head is mainly divided into a rubber forceps head with a large friction coefficient and a forceps head with a cavity formed after clamping However, during the operation, due to the irregular shape, hard and brittle characteristics of stones, no matter whether it is a rubber forceps head or a forceps head that can form a cavity, excessive force may cause the stones to break, and the stones are easily broken after breaking. More fine stone fragments are formed and cannot be cleaned ef...

Problems solved by technology

Existing bladder stone removal forceps are composed of a handle and a forceps head, which have a simple structure and adopt the principle of mechanical mechanics to capture stones. The forceps head is mainly divided into a rubber forceps head with a large friction coefficient and a forceps head with a cavity formed after clamping However, during the operation, due to the irregular shape, hard and brittle characteristics of stones, no matter whether it is a rubber forceps head or a forceps head that can form a cavity, excessive force may cause the stones to break, and the stones are easily broken after breaking. Formation of more fine stone fragments that cannot be cleaned effectively

In addition, there is also the stone-taking mirror for the bladder and kidney pelvis of Chinese patent CN 101214163B, which is mainly composed of stone-taking forceps clamp assembly, stone-taking forceps clamp channel tube, gravel channel tube, optical fiber channel tube, water inlet channel tube and endoscope assembly. The functions of crushing stones, absorbing crushed stones and ingesting crushed stones can be used in stone removal surgery in most cases, but this stone removal mirror has the problems of high operation requirements, complicated structure and high cost
