Anti-blocking type valve of flush-suction device and flush-suction device

Abstract

The invention provides an anti-blocking type valve of a flush-suction device. The valve comprises a valve switch, a valve element and a seal sleeve, wherein the valve element is mounted in a valve element mounting groove of the valve switch, and the seal sleeve is compressed between the bottom of the valve element and the bottom of the valve switch, so that the sealing is formed. The valve element is embedded in the valve element mounting groove of the valve switch, and a rotation shaft of the valve element sequentially passes through a rotation shaft hole of the seal sleeve and a rotation shaft hole of the valve switch; the valve switch can rotate around the valve element, and the valve element and the seal sleeve are stationary. A shifting switch of the valve switch is stirred rightwards, and a water inlet channel is connected for flushing the abdominal cavity; the shifting switch of the valve switch is stirred leftwards, and a water outlet channel is connected for sucking and discharging the liquid in the abdominal cavity out of the body. The flush-suction device comprises the anti-blocking type valve, the use is convenient, the pipe diameter of the liquid channel of the flush-suction device is consistent, no dead angles exist, and thus the problem that during the sucking out process, the medical liquid containing the tiny tissue easily causes blockage is solved.

Description

technical field [0001] The invention relates to a laparoscopic surgical instrument, in particular to a valve and an insufflator of an anti-blocking type inspirator used in laparoscopic surgery. Background technique [0002] Laparoscopic surgery has been more and more widely used, and the minimally invasive laparoscopy has played a huge role in the diagnosis and treatment of abdominal diseases. During laparoscopic abdominal surgery, it is sometimes necessary to perform abdominal flushing, and at the same time, suction the flushing fluid to the outside of the body to achieve the purpose of cleaning the abdominal cavity. [0003] The flushing function and the suction function of the flushing device in the prior art are generally switched by two buttons arranged side by side. During the use process, the button needs to be pressed all the time to ensure the flushing or suction action, and the use process is inconvenient; Moreover, the side-by-side design of the two buttons is pr...

Problems solved by technology

[0003] In the prior art, the flushing function and the suction function of the flushing device are generally switched by two buttons placed side by side. During use, the button needs to be pressed all the time to ensure the flushing or suction action, which is inconvenient to use; Moreover, the side-by-side design of the two buttons is prone to misuse

In addition, if the pumped liquid contains microscopic tissues, these microscopic tissues are likely to be blocked at the variable diameter of the pipeline through which the liquid passes. Therefore, it is necessary to improve the flushing device in the prior art
