Description

Puncture outfit for full-plastic cone laparoscope

Technical Field

The utility model belongs to the technical field of surgery operation medical instrument technique and specifically relates to a puncture ware for peritoneoscope of plastic cone.

Background

Laparoscopic surgery is a procedure performed using a laparoscope and its associated instruments: the method comprises the steps of using a cold light source to provide illumination, inserting a laparoscope lens (the diameter is 3-10 mm) into the abdominal cavity, conducting an image shot by the laparoscope lens to a post-stage signal processing system through an optical fiber by using a digital camera shooting technology, and displaying the image on a special monitor in real time. Then, the doctor analyzes and judges the state of the patient through the images of different angles of the organs of the patient displayed on the monitor screen, and performs the operation by using a special laparoscopic minimally invasive instrument.

The puncture outfit for the laparoscope is an indispensable surgical instrument in the laparoscopic surgery, and the puncture outfit for the laparoscope in China generally has the following defects: 1. in a clinical operation, because the skin tissue is a layer of horizontal and vertical skin tissue, resistance can be generated when the skin tissue is punctured, and the internal organs can be damaged by the excessive exertion of force;

2. when the puncture cannula and the puncture cone enter a human body to a certain extent, whether the tip of the puncture cone reaches the thoracic cavity or the abdominal cavity or not cannot be directly judged, medical staff may still push the puncture cannula and the puncture cone continuously, so that the puncture cone can injure viscera, and serious medical accidents are caused;

3. the existing laparoscope puncture outfit can not be effectively fixed on the abdominal wall, when in use, the whole inner needle sleeve can be easily brought out in the process of pulling an inserted instrument outwards, thereby affecting the operation, easily causing the operation time to be prolonged and even generating complications such as subcutaneous emphysema and the like, and being not beneficial to the treatment of patients;

4. in the puncture process, blood can be generated, and the inner wall of the inner needle sleeve is always remained with blood, tissues and fat when the puncture cone is withdrawn, so that the puncture cone not only can influence the in and out of the surgical instrument, but also can seriously influence the definition of a lens of a monitor and interfere the surgical field.
