Problems solved by technology

However, the use of existing laparoscopic related surgical instruments for surgery has the following disadvantages: when the ovarian cyst is large, it is easy to break the cyst and make the cyst cells diffuse, which increases the risk of surgery. In addition, when the cyst is large, the operation space is relatively large. Smaller, the surgical field of view is affected, and the risk of miscutting or puncturing the cyst is prone to occur

Abstract

The invention discloses an ovarian tumor puncture outfit with an anti-dispersion characteristic. The ovarian tumor puncture outfit comprises a suction tube, a puncture needle, an inner needle sheath and an outer needle sheath arranged outside the inner needle sheath in a sleeving mode. A horn-mouth-shaped suction cup is arranged at the front end of the inner needle sheath, and the inner needle sheath and the suction cup are both made of flexible materials. The puncture needle is arranged at the front end of the suction tube, the suction tube and the puncture needle are arranged in the inner needle sheath, and the suction tube and the puncture needle can slide in the inner needle sheath. The ovarian tumor puncture outfit can be directly used for puncturing tumors and removing tumor cells and can clamp tumors, and therefore tumors can be conveniently stripped and removed.

Description

technical field [0001] The invention relates to a medical device, in particular to an ovarian tumor puncturer with anti-diffusion properties. Background technique [0002] Laparoscopic surgery is an operation performed using laparoscope, ultrasonic scalpel, electrocoagulation scalpel and other related instruments. It is a newly developed minimally invasive method, which is suitable for ovarian cyst removal and hysterectomy. However, the use of existing laparoscopic related surgical instruments for surgery has the following disadvantages: when the ovarian cyst is large, it is easy to break the cyst and make the cyst cells diffuse, which increases the risk of surgery. In addition, when the cyst is large, the operation space is relatively large. If it becomes smaller, the surgical field of view is affected, and the risk of miscutting or puncturing the cyst is prone to occur. [0003] For this reason, be badly in need of developing a kind of laparoscopic surgical instrument to ...
