Puncture outfit

Abstract

The invention discloses a puncture outfit, which comprises a puncture rod, a sheath component and an exhaust port. The puncture rod is used for forming a through hole, and the sheath component sleevesthe outer side of the puncture rod and serves as a surgical channel. The sheath component comprises an inner tube and an outer tube, the outer tube sleeves the outer side of the inner tube to form aninterlayer, a thin end of the inner tube is provided with an opening, and the interlayer is internally provided with a smoke exhaust channel through which the opening and the vent port are communicated. Smoke is exhausted out of a surgical space when gas enters the surgical space, so that lens blurring caused by smoke can be eliminated, influences on sight of medical personnel are avoided, and surgical efficiency is improved. In addition, an air sac seal structure is delicate in design and reliable in sealing of surgical instruments in different sizes, and safety in product clinical application is achieved.

Description

technical field [0001] The invention relates to the medical field, in particular to a trocar. Background technique [0002] Disposable puncture device is an important instrument in laparoscopic surgery. It is a supporting surgical instrument for external thoracic and external laparoscopy. . With the development of imaging technology and camera technology, minimally invasive surgical methods represented by laparoscopic surgery have developed rapidly in recent years, especially in gynecology, general surgery and other operations involving the abdominal cavity, which are gradually changing from open to intracavitary surgery. minimally invasive surgery. In laparoscopic surgery, 2 to 5 puncture holes are generally used, one for placing the laparoscope, and the rest for placing surgical instruments. The outer diameter of surgical instruments is roughly divided into 5mm, 10mm, 12mm, 15mm, etc. It is equipped with a suitable inner diameter puncture cannula to avoid pneumoperitone...

Problems solved by technology

In laparoscopic surgery, 2 to 5 puncture holes are generally used, one for placing the laparoscope, and the rest for placing surgical instruments. The outer diameter of surgical instruments is roughly divided into 5mm, 10mm, 12mm, 15mm, etc. Matching matching inner diameter puncture cannula to avoid pneumoperitoneum leakage and affect the operation

[0003] In clinical medical treatment, when the electric knife in the trocar burns or electrocoagulates human tissue, it will inevitably produce a large amount of smoke and water vapor. The smoke produced by the combustion of this organic matter is a strong carcinogen, which will harm the operator and The medical staff in the operating room cause unnecessary injuries, and when performing deep operations on the human body, especially when electrocauterying deep blood vessels and other important organs, the smoke will blur the electron microscope inside, affecting the sight of the medical staff, causing difficulty in hemostasis, and even Cause blindness or hectic operation, so a smoke removal device is needed to ensure the smooth operation
