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 easy angle adjustment puncture device for ovarian tumors. The device comprises a cannula, a pipette, a puncture needle and two steel wires made from spring steel. The cannula is provided with a flared chuck, and the cannula, the pipette and the chuck are made from flexible materials. Inside the cannula, there are two channels extending in the axial direction of the cannula, wherein the two steel wires are respectively inserted. The front ends of the two steel wires are curved naturally, each wire is capable with rotatory operation in the channel. The puncture needle is arranged in the front end of the pipette, the pipette and the puncture needle, which are arranged in the cannula, are telescopically slideable upward along the cannula. The pipette and the puncture needle are respectively spaced from the inner wall of the cannula. The easy angle adjustment puncture device for ovarian tumors not only is capable with puncturing directly to the tumors excluding the tumor cells, but also is capable of holding the tumors, and is convenient of peeling and removing the tumors.

Description

technical field [0001] The invention relates to a medical instrument, in particular to an ovarian tumor puncturer which is convenient to adjust the angle. 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 i...
