Gall bladder ejection puncture outfit

Abstract

The invention discloses a gall bladder ejection puncture outfit to solve the problem that a thick drainage catheter cannot be inserted at a time in the present clinical process of inserting a catheter into the gall bladder. The gall bladder ejection puncture outfit comprises an ejector base catheter, a back gland and a piston, wherein the back gland is arranged at one end of the ejector base catheter, the piston is arranged in the ejector base catheter and can move relative to the ejector base catheter, and one end of the piston extends out of the ejector base catheter and penetrates through the back gland. The end, close to the back gland, of the piston is sleeved with a spring located in the ejector base catheter, and the piston is further provided with a protrusion, wherein the protrusion and the back gland compress the spring together, and the protrusion controls the piston to move relative to the ejector base catheter; the end, far away from the back gland, of the piston is provided with a puncture needle with the needle point located outside the ejector base catheter; the ejector base catheter is internally provided with a locking piece used for preventing the piston from moving relative to the ejector base catheter through the elasticity of the spring. According to the gall bladder ejection puncture outfit, the thick drainage catheter can be inserted at a time, and the fixed-depth puncturing can be achieved during the puncturing process.

Description

technical field [0001] The invention relates to a gallbladder ejection puncturer. Background technique [0002] Gallbladder puncture catheterization is a commonly used technique in clinical practice. It is often used in the treatment of acute cholecystitis with gallbladder effusion. It can quickly relieve the condition of patients with acute cholecystitis and subside inflammation, creating conditions for the next step of gallbladder surgery. It can also be used as a definitive treatment for some elderly and infirm patients who cannot afford surgery. In addition, for some patients with gallbladder stones who have suitable conditions, the drainage tube built into the gallbladder can be inserted into the choledochoscope for stone removal, so as to achieve the therapeutic purpose of gallbladder stone removal. Whether it is puncture drainage or choledochoscopy stone removal through the placed drainage tube, a thicker drainage tube needs to be placed. From the perspective of...
