Abstract

The utility model discloses a puncture outfit for cardiothoracic surgery, which comprises a needle tube and a puncture needle head, wherein a piston is arranged in the needle tube; the rear end of the piston is connected with a piston rod; a one-way valve I which only allows to flow into towards the direction of a needle tube cavity is arranged at the connected part of the puncture needle head and the needle tube; a communicated hollow tubular cavity is arranged in the piston rod and the piston; and a one-way valve II which is only used for liquid in the needle tube cavity to flow out of the hollow tubular cavity of the piston rod is arranged at the connected part of the piston rod and the piston. The puncture outfit is simple and convenient to operate and realizes the continuous extraction of the liquid, thus the pains of patients are relieved and the labor intensity for medical staff is reduced. The puncture outfit is especially suitable for thoracic surgery.

Description

A kind of cardiothoracic surgery perforator

Technical field

This utility model relates to a kind of medical apparatus and instruments, the perforator that especially a kind of cardiothoracic surgery uses.

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 piercing needle, 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 piercing needle, as follows operation is very loaded down with trivial details, has also increased medical personnel's labor intensity and has increased patient's misery.

The utility model content

Task of the present utility model is that a kind of perforator that is used for the energy continuous drawing liquid of cardiothoracic surgery is provided at the deficiency of above technology.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of cardiothoracic surgery perforator, comprise needle tubing, piercing needle, be provided with piston in the needle tubing, piston rear end connects piston rod, the check valve I that piercing needle and needle tubing junction have a permission to flow into to the needle lumen direction, described piston rod and piston have a hollow tube chamber that connects, and have one only to supply in the needle lumen liquid to the effusive check valve II of piston rod hollow tube chamber in piston rod and piston junction.

The end of described piston rod has for the connection-peg that connects flexible pipe, with the convenient mozzle that connects.

During use, liquid is extracted in puncture as required, after extracting a full packages liquid, piston is return initial point again, at this moment because the check valve I of junction, syringe needle rear end sealing, liquid in the needle lumen can not be back in the patient thoracic cavity yet, but can enter the cavity of piston rod and water conservancy diversion goes out through check valve along the cavity of piston; When extracting the second pipe liquid again, the check valve II of piston rod front end and piston junction closes, and the withdrawing piston can make and form new negative pressure in the needle lumen, under this suction function, extracts the second pipe pleural fluid smoothly.Can puncture once like this, come continuous drawing patient's pleural fluid, liquid be flowed in the specified containers by mozzle by withdrawing piston repeatedly, 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.

Among the figure, 1. piercing needle, 2. check valve I, 3. needle tubing, 4. piston, 5. check valve II, 6. handle, 7. piston rod, 8. handle, 9. connector, 10. needle lumen, 11. hollow tube chambers.

The specific embodiment

Below in conjunction with Figure of description this utility model is done following detailed description.

As shown in the figure, a kind of cardiothoracic surgery perforator, comprise needle tubing 3, piercing needle 1, be provided with piston 4 in the needle tubing 3, piston 4 rear ends connect piston rod 7, piercing needle 1 has the check valve I 2 of a permission to the inflow of needle lumen 10 directions with needle tubing 3 junctions, described piston rod 7 and piston 4 have a hollow tube chamber 11 that connects, have one only to supply in the needle lumen 10 liquid to piston rod hollow tube chamber 11 effusive check valve II 5 in piston rod 7 and piston 4 junctions, the end of described piston rod has for the connection-peg that connects flexible pipe, with the convenient mozzle that connects.

Claims

1. cardiothoracic surgery perforator, comprise needle tubing, piercing needle, be provided with piston in the needle tubing, piston rear end connects piston rod, it is characterized in that the check valve I that described piercing needle and needle tubing junction have a permission to flow into to the needle lumen direction, described piston rod and piston have a hollow tube chamber that connects, and have one only to supply in the needle lumen liquid to the effusive check valve II of piston rod hollow tube chamber in piston rod and piston junction.

2. a kind of cardiothoracic surgery perforator as claimed in claim 1 is characterized in that having for the connection-peg that connects flexible pipe at the end of described piston rod.
