Anti-plugging multifunctional surgical aspirator

Abstract

The invention provides an anti-plugging multifunctional surgical aspirator, which comprises a handle (1) and an aspiration washing head (2), and is characterized in that: a negative pressure passageway (3) and a washing passageway (4) are arranged in the aspiration washing head (2); the negative pressure passageway (3) is communicated with a negative pressure generating device through a negative pressure aspirating interface (5); the washing passageway (4) is communicated with the output end of a washing water inlet passageway (7) on the handle (1) through a washing passageway switchover interface (6); the washing passageway switchover interface (6) is rotatably arranged in one end, close to the handle (1), of the aspiration washing head (2); and a flow guide passageway (8) which is respectively communicated with the washing passageway (4) and the negative pressure passageway (3) by rotation so as to enter the normal washing procedure or dredge the negative pressure passageway (3). The anti-plugging multifunctional surgical aspirator can be used for washing, is capable of preventing plugging, has simple structure and is convenient to use.

Description

technical field [0001] The invention relates to a medical device, in particular to a surgical aspirator for flushing and aspirating a wound during an operation, in particular to an anti-blocking multifunctional surgical aspirator. Background technique [0002] As we all know, it is required to maintain a clear surgical field of view during surgical operations, so that the surgeon can perform precise operations on the surgical site. Therefore, it is necessary to perform negative pressure suction on the continuously oozing blood and excised tissues and tissue fluids during the operation. And use normal saline to continuously flush the bleeding site to ensure a clear surgical field. Therefore, when performing negative pressure suction during the operation, not only the suction head with negative pressure suction function must be used, but also the suction head should be able to absorb normal saline while suctioning. At the same time, an additional auxiliary device is required f...

Problems solved by technology

[0003] The purpose of the present invention is to design a method that can directly use the flushing channel to solve the problem that the existing negative pressure suction head with flushing must be replaced or removed for flushing and dredging when the negative pressure channel is blocked, resulting in increased operation cost or prolonged operation time.
