A laparoscopic flushing and drainage device with double sheaths

Abstract

The invention relates to a laparoscopic flushing and drainage device with double sheaths, comprising a first sheath, a second sheath and a flushing and drainage tube; the first sheath has a channel for the second sheath to be inserted into, and the second sheath The tube has a channel for the irrigation and drainage tube to be inserted into. The second sheath includes a tube body, a sealing valve arranged in the middle of the tube body, and a scraper arranged between the sealing valve and the head end of the tube body. The irrigation and drainage tube includes a flushing tube, The drainage tube and the rear tube body, the flushing tube and the drainage tube have arcuate cross-sections, there is a gap between the flushing tube and the drainage tube for the pin shaft and the scraper to pass through, the head end of the drainage tube is closed, and the vertical Both the straight side wall and the curved side wall are provided with internal drainage holes. The laparoscopic flushing and drainage device of the present invention can be quickly and accurately inserted through the abdominal incision, can prevent blood clots in the abdominal cavity from blocking the drainage hole, and after the flushing and drainage tube is pulled out, the sheath tube will be automatically closed without affecting the pneumoperitoneum effect.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a laparoscopic flushing and drainage device with double sheaths. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive surgical method in recent years, and it is an inevitable trend of future surgical development. With the development of scientific and technological means, coupled with the increasingly skilled operation of doctors, and because laparoscopic surgery itself has the advantages of small surgical trauma, wide operating field of view, quick recovery of patients, and less pain, many open surgeries in the past have now been performed. replaced by endovascular surgery. As a representative of minimally invasive surgery, it is widely used in the field of surgery, involving many diseases and operations, and is welcomed by patients. [0003] In laparoscopic surgery, medical personnel have to complete a series of actions, inclu...

Problems solved by technology

The flushing pipe commonly used in the prior art is that the water inlet and the water outlet are the same lumen, which is adjusted by a changeover switch. The defect is that the water cannot be sucked in while absorbing water. In addition, more blood clots are contained in the flushing liquid sucked by negative pressure, which is sucked into the flushing rod, causing the flushing device to be blocked, resulting in prolonged operation time and increased operation risk

In addition, most of the existing irrigation tubes extend directly into the patient's abdominal cavity from the abdominal incision. Since the holding part of the irrigation device is relatively backward, it is difficult to accurately align the incision and insert it at the first time. , if the irrigator is pulled out, the incision in the abdominal cavity cannot be closed, which will affect the pneumoperitoneum effect
