Description
Technical field
This utility model relates to thoracic surgery medical instruments field, is specifically a kind of thoracic surgery perforator.
Background technology
When patient is diagnosed as ambition hydrops, Therapeutic Method conventional clinically adopts paracentesis to extract hydrops, and concrete operation measure uses the syringe of large size to be equipped with piercing needle, thrusts the operation carrying out hydrops extraction in thoracic cavity with piercing needle.When the hydrops needing to extract is less, this operation can once complete, but when the hydrops needing to extract is more, just must extract in multiple times repeatedly, all syringe must be pulled out each time, after liquid in pipe of draining, then syringe is connected with piercing needle.When needs repeatedly extract, such operation increases the labor intensity of medical personnel undoubtedly, also extends the operating time for the treatment of to a certain extent, increases the misery of patient.
In view of this, Chinese patent 201220704165.3 provides a kind of cardiothoracic surgery perforator device, includes and cuts valve, piston rod, plunger shaft check valve, piston, needle tubing, front end check valve, puncture needle, draws liquid sleeve pipe and exterior liquid connector.Be provided with front end check valve in the front end of needle tubing, the front end of needle tubing is provided with puncture needle, in the outside of puncture needle, be arranged with and draw liquid sleeve pipe, the front end of drawing liquid sleeve pipe, for drawing the main suction inlet of liquid, the side, front end of drawing liquid sleeve pipe is also provided with and draws liquid side draught mouth.Be provided with piston in needle tubing, the piston rod being connected with interior empty form below of piston, in the front end of piston rod, be provided with plunger shaft check valve, the rear end of piston rod is exterior liquid connector, in the side of exterior liquid connector, is provided with and cuts valve.The hose connection apocenosis bag of discharge opeing can be used, implement the discharge opeing of conitnuous forms.This utility model overall structure is simple, and easy for operation, good stability, reliability is high.Use this utility model can extract hydrops in thoracic cavity continuously, reduce the operating time that hydrops extracts.In order to alleviate the misery of patient, need the body fluid slowly extracted evenly in human body, this just needs the pressure between control piston and needle tubing, but this technology can not measure the pressure between piston and needle tubing, is difficult to the pressure between control piston and needle tubing.
Utility model content
