Built-in aspirator for laparoscope operation

Abstract

The invention discloses a built-in aspirator for laparoscope operation, which comprises an aspiration head, a hose, an aspiration switch and a washing switch, wherein one end of the hose is communicated with the aspiration head, the other end of the hose is divided into two pipelines, one of the pipelines is connected with the aspiration switch, and the other pipeline is connected with the washing switch; and an aspiration hole I communicated with the hose and a grasping component for allowing forceps to grasp are respectively formed on the aspiration head. In the operation process, the hose of the aspirator enters enterocoelia from a small hole on an abdominal wall and shares the same small hole with a trocar, so the aspirator is not needed to be removed to leave space for other instruments in the operation process, and the position where the aspirator enters the abdominal wall is not changed any more in the operation process; and the aspirator is in the enterocoelia all the time, sothe aspiration head can be grasped by using the forceps at any time to absorb exudation and seepage, operators absorb the exudation and the seepage instantly and conveniently, and the visual field iskept distinct all the time in the operation process. Simultaneously the trouble of replacing the instruments is reduced, the labor strength of the operators is relieved, the operation time is shortened, and the operation risks are reduced.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a laparoscopic operation aspirator. Background technique [0002] In the 21st century, minimally invasive surgery represented by laparoscopy has become an important direction of medical development, and most abdominal visceral operations can be completed under laparoscopy. Due to the cutting and separation of tissues during the operation, fat liquefaction and damage to small blood vessels are caused. It is inevitable to use a suction device to absorb the bleeding and exudate produced by the operation. Peritoneal irrigation is often required towards the end of the procedure, which also requires suction of the irrigation fluid. [0003] At present, the suction device used in laparoscopic surgery is a long tube type, the suction and flushing switch is outside the body, and the suction device enters and exits the abdominal cavity through the puncture hole in the abdomina...

AI Technical Summary

Problems solved by technology

Laparoscopic surgery requires a small hole in the abdominal wall to serve as a channel for instruments such as forceps, electric hooks, and mirrors to enter and exit the abdominal cavity. Since the position of the instrument needs to be changed according to the operator's operation requirements, there is no small hole dedicated to the entry and exit of a certain instrument. In the abdominal cavity, it is very common for one hole to be used for multiple purposes. At the same time, because the aspirator is a hard tube, the range angle that can be reached is limited. In order to attract liquid from different parts, the position of the aspirator needs to be changed frequently; The aspirator enters and exits the abdominal cavity through different small holes in the abdominal wall multiple times. Such an operation is time-consuming and laborious, and the fluid is not sucked in time, which increases the workload of the surgeon and the operation time, and indirectly increases the risk of the operation.

[0004] In addition, due to the limitation of the puncture card, the diameter of the aspirator is less than 5 mm. During the aspiration, the lumen is often blocked due to the inhalation of soft tissues such as blood clots, intestinal fat, omentum, etc., and the aspiration is forced to be terminated, and even the aspirator needs to be moved. or help with pliers to unblock
