Abstract

The invention discloses an aspirator convenient for positioning. The aspirator comprises an injector cylinder, a rubber ring, a push rod and a pull handle which are successively installed in the injector cylinder from inside to outside, and a two-way cock connected to the liquid outlet of the injector cylinder. A side plate of the push rod is provided with a push stopping device. The push stoppingdevice comprises a plurality of mutually parallelly arranged push stopping elastic sheets installed at one side plate of the push rod. The push stopping elastic sheets are slantwise installed towardsa direction of the rubber ring. The bottom of the push stopping elastic sheets is fixed on the side plate of the push rod, and the top is higher than the edge of the side plate of the push rod. The aspirator convenient for positioning is capable for fixing a state of the aspirator convenient for positioning through the push stopping device, wherein the operation is simple, convenient, and rapid,greatly simplifying a vacuum aspiration operation, improving the success rate and safety of the operation, further improving the operation efficiency, and shortening the operation time, has the important practical application, and is beneficial to popularization.

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. At present, the aspirator used for easy positioning after puncture is a common syringe on the market. During the operation, the instrument 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 in...
