Abstract
The utility model discloses a puncture device for cardiothoracic surgery, which belongs to the field of medical instrument. The puncture device comprises a tube body which is internally provided with a piston. The front part of the piston is connected with a spring. The front end of the tube body is respectively connected with a draft tube and a drainage tube. The draft tube is internally provided with a check valve that conducts outwards. The drainage tube is internally provided with a check valve that conducts inwards to the tube body. The puncture device has the following advantages: simple operation, effectively reduced pain of patient, and effectively reduced labor intensity of medical personnel.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of perforator that is used for cardiothoracic surgery.
Background technology
At present, the liquid extracting device that the treatment of cardiothoracic surgery puncture property is used, its structure is that the front end of syringe is with puncture tube, when the liquid that extracts more after a little while, can once finish, but the liquid that ought extract more for a long time, must repeated multiple times extract, and must pull out syringe each time, pour out liquid in pipe, and then be connected with puncture tube, as follows operation is very loaded down with trivial details, has improved medical personnel's labor intensity and has increased patient's misery.
The utility model content
Technical assignment of the present utility model is to provide a kind of perforator that is used for cardiothoracic surgery at the deficiency of above technology.
The technical scheme that its technical problem that solves this utility model adopts is a kind of perforator that is used for cardiothoracic surgery, comprise body, in described body, be provided with piston, the front of described piston connects spring, front end at described body is connected with mozzle and drainage tube respectively, in described mozzle, be provided with the check valve of outside conducting, in described drainage tube, be provided with the check valve of conducting in body.
During use, promote piston, spring is compressed, unclamp piston then, piston is outwards motion under the effect of spring, forms negative pressure in the body, the drainage tube internal check valve is opened this moment, mozzle internal check valve closure, and liquid will attracted in the body, promote piston compression spring again, drainage tube internal check valve closure this moment, the mozzle internal check valve is opened, and manages intravital liquid and flows in the specified containers by mozzle, and so forth, up to liquid is pumped.
The utility model has the advantages that easy and simple to handlely, realized continuous drawing liquid, thereby alleviated patient suffering and medical personnel's labor intensity.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
