Cyst treating instrument

Abstract

The invention discloses a cyst treating instrument, which comprises a catheter, a puncture needle and a connector. One end of the catheter is a puncture end with a memory function, and the connector is arranged at one end, opposite to the puncture end, of the catheter. After the puncture needle is withdrawn, the puncture end is bent to hook a cyst wall. In cyst treatment, a medical worker insertsthe puncture needle into the catheter to make the catheter and the puncture end linear, then inserts the catheter and the puncture needle into a human body to penetrate into a cyst and finally withdraws the puncture needle. Due to the memory function of the puncture end, the withdrawn puncture needle is bent and capable of hooking the cyst wall to prevent the puncture end from slipping out of thecyst, other tissues are protected from infection of liquid in the cyst, and infection probability increase caused by secondary operation resulted from slipping of the catheter can be avoided.

Description

technical field [0001] The invention relates to a medical device, more specifically to a cyst treatment instrument. Background technique [0002] Cyst is a benign disease that can grow on the surface of the human body or in internal organs; a cyst is a benign cystic mass that grows in a certain organ in the body, and the nature of its contents is liquid. Generally speaking, the common cysts are "kidney cyst", "liver cyst", "simple ovarian cyst" and "chocolate cyst". Renal cysts are divided into simple solitary renal cysts and polycystic kidneys. [0003] Currently, there are three main methods of treatment for cysts: [0004] 1. It is the traditional method of surgically cutting cysts, that is, treating cysts with fenestration and drainage or stripping. In this method, the incision is long, the bleeding is heavy, the trauma is heavy, the cost is high, and it is easy to relapse. [0005] The second is to cut the cyst under laparoscopy. Although it is only a hole, the trau...

AI Technical Summary

Problems solved by technology

In this method, the incision is long, the bleeding is heavy, the trauma is heavy, the cost is high, and it is easy to relapse.

[0005] 2. The cyst is cut under laparoscopy. Although it is only a hole, the trauma is much smaller than that of surgery, but it still needs to be hospitalized, and the cost is not small

However, after the catheter is inserted into the cyst, due to the activities of the human body, it is easy to prolapse from the cyst, causing the fluid in the cyst to infect other tissues
