Hole-reducing laparoscope puncture outfit with protective sleeve

Abstract

The invention discloses a hole-reducing laparoscope puncture outfit with a protective sleeve. The puncture outfit comprises a sleeve and a rod-shaped inner core inserted in the sleeve; the cross section of the sleeve is elliptical, and the cross section shape of the rod part of the inner core matches that of the sleeve; and the lower end of the rod part is provided with a protective sliding sleeve, and the protective sliding sleeve can slide up and down along a groove so as to automatically pop out a shielding tip at one instant when the puncture is finished. The laparoscopic puncture outfit with the structure enlarges the cross sectional area of the sleeve, so that the sleeve can simultaneously accommodate two surgical instruments for operation. The puncture outfit reduces the puncture times and the number of puncture holes, relieves the pain of patients and is more beautiful. Meanwhile, the protective sliding sleeve is arranged at the tip of the inner core, so that the tip can be shielded at one instant when the puncture outfit enters the abdominal cavity, the tip is prevented from cutting or pricking internal organs, and the occurrence probability of medical accidents is greatlyreduced.

Description

technical field [0001] The invention relates to a laparoscopic trocar. Background technique [0002] The laparoscopic trocar is a single-use, suitable for the delivery of gas in minimally invasive surgery and the creation of channels for endoscopes and surgical instruments to enter and exit the body cavity from the outside world, various laparoscopic operations, including minimally invasive surgery, gynecology Minimally invasive surgery, thoracic surgery, urology and other laparoscopic surgery can be matched with various laparoscopic TV systems at home and abroad. [0003] Although the laparoscopic puncture device is minimally invasive, it still leaves scars on the human body and affects the appearance. Therefore, it is necessary to reduce the number of punctures and holes as much as possible. In addition, due to the good toughness of human tissue, in order to achieve a minimally invasive effect and achieve an aesthetic effect, the wound of the patient is very small, so the...

[0003] Although the laparoscopic trocar is minimally invasive, it still leaves scars on the human body and affects the appearance, so it is necessary to reduce the number of punctures and holes as much as possible

In addition, due to the good toughness of human tissue, in order to achieve a minimally invasive effect and achieve an aesthetic effect, the wound of the patient is very small, so the skin tissue will generate a lot of resistance when the doctor performs the puncture, which greatly increases the difficulty of surgical puncture
