Abstract

The invention discloses a multifunctional aspirator, comprising an injector barrel, a rubber ring, a pushing rod, a pulling handle and a two-way plug cock, wherein the rubber ring, the pushing rod andthe pulling handle are arranged in the injector barrel successively from inside to outside, the two-way plug cock is connected to the liquid outlet of the injector barrel, a thrust brake is arrangedon the side plate of the pushing rod, the thrust brake comprises a plurality of anti-thrust elastic sheets which are arranged in parallel at one side plate of the pushing rod, the anti-thrust elasticsheets are obliquely arranged in the direction of facing the rubber ring, the bottoms of the anti-thrust elastic sheets are fixed on the side plate of the pushing rod, and the tops of the anti-thrustelastic sheets are higher than the edge of the side plate of the pushing rod. According to the multifunctional aspirator provided by the invention, the state of the multifunctional aspirator can be fixed by the thrust brake, the operation is simple, convenient and fast, the operation of vacuum aspiration is greatly simplified, the success rate and the safety of the operation are improved, the operation efficiency can be further improved, and the operation time is shortened; the multifunctional aspirator has important practical application value, and is beneficial to popularizing.

Description

technical field [0001] The invention relates to a medical device, in particular to an aspirator. Background technique [0002] The endoscopic negative pressure biopsy technique and the percutaneous negative pressure biopsy technique have been developed maturely all over the world in the past 30 years. This technology is to obtain diagnostic specimens of cells, tissues, and fluids through puncture, and can also perform puncture and aspiration therapy, and can also achieve the purpose of injection therapy. During the process, the equipment operator needs to pull the syringe piston to form a negative pressure, and hold the syringe piston with both hands for a long time to fix the piston to ensure negative pressure. This method causes sore hands of the equipment operator, and if the negative pressure is unstable, the obtained cells, tissues or fluids will be injected back into the patient's body. Contents of the invention [0003] Purpose of the invention: the purpose of the...
