Abstract
The utility model discloses a puncture needle for cardiological interventional therapy. The puncture needle for the cardiological interventional therapy comprises the following components: a needle head, a needle handle and a sleeve which is equipped at the tail end of the needle handle, wherein, the back end of the needle handle is also provided with a drainage tube which is communicated with an inner pipe of the needle head. An elastic membrane is provided at the back end of the needle handle and above the sleeve. The puncture needle simply and effectively settles problems of facilitating blood color observation and placing a guide wire in interventional therapy. Simultaneously, the puncture needle for the cardiological interventional therapy has the following advantages: high convenience in use, and high suitability for the prior-art cardiological interventional therapy surgery.
Description
Technical field
This utility model relates to a kind of medical apparatus, especially a kind of intracardiac section interventional therapy puncture needle.
Background technology
At present, when carrying out the cardiovascular interventional therapy, directly thrust blood vessel or thrust blood vessel with puncture needle with common syringe, and then remove needle tubing and keep syringe needle, observe the blood color and judge, in syringe needle, insert seal wire again, like this, seal wire is not easy to insert in the process of carrying out, and has increased work difficulty to the medical worker.
Observe the blood color easily and conveniently insert the problem of seal wire when therefore, needing a kind of new intracardiac section interventional therapy to carry out interventional therapy with better solution with puncture needle.
Summary of the invention
In view of this, this utility model is devoted to observe the blood color easily when better interventional therapy is carried out in solution and conveniently insert the problem of seal wire, has proposed a kind of intracardiac section interventional therapy puncture needle.
The technical solution adopted in the utility model is:
A kind of intracardiac section interventional therapy comprises syringe needle, needle handle with puncture needle and is arranged on the sleeve pipe of needle handle tail end that wherein, the rear end of described needle handle is provided with the drainage tube that is connected with pipe in the syringe needle, also is provided with elastica before the rear end of needle handle, the sleeve pipe.
Above-mentioned drainage tube that direction is set is parallel with syringe needle.Be arranged in parallel and make things convenient for the fixing and position adjustment of syringe needle.
Above-mentioned drainage tube is provided with switch.
The diameter of above-mentioned elastica is greater than casing diameter.
Above-mentioned syringe needle and telescopic length ratio are 3: 2.
The beneficial effects of the utility model are:
This utility model is simple in structure but efficiently solve when carrying out interventional therapy and to observe the blood color easily and conveniently to insert the problem of seal wire, and is easy to use simultaneously, relatively is suitable for existing intracardiac interventional therapy operation.
Description of drawings
Below with reference to accompanying drawings specific embodiments of the present utility model is described in detail, wherein:
Fig. 1 is a structure drawing of device of the present utility model;
Wherein, 1-syringe needle, 2-needle handle, 3-elastica, 4-sleeve pipe, 5-drainage tube, 6-switch.
The specific embodiment
To observe the blood color when carrying out interventional therapy in order solving easily and conveniently to insert the problem of seal wire, this utility model provides a kind of intracardiac section interventional therapy puncture needle.Next specify this intracardiac section interventional therapy puncture needle.
Fig. 1 illustrates structure drawing of device of the present utility model.This intracardiac section interventional therapy comprises syringe needle 1, needle handle 2 with puncture needle and is arranged on the sleeve pipe 4 of needle handle 2 tail ends, wherein, the rear end of needle handle 2 is provided with the drainage tube 5 that is connected with pipe in the syringe needle 1, also be provided with elastica 3 before the rear end of needle handle 2, the sleeve pipe 4, during use, drainage tube 5 can be earlier to blood drainage, the convenient blood color of observing, thereby be judged as venous blood or arterial blood, sleeve pipe 4 can better draw seal wire.
Above-mentioned drainage tube 5 that direction is set is parallel with syringe needle 1.
Above-mentioned drainage tube 5 is provided with switch 6, can the better controlled blood flow.
The diameter of above-mentioned elastica 3 is greater than sleeve pipe 4 diameters, thereby preventing that blood from flowing out from needle handle pollutes.
Above-mentioned syringe needle 1 is 3: 2 with the length ratio of sleeve pipe 4.
More than specific descriptions of the present utility model are intended to illustrate the implementation of specific embodiments can not be interpreted as it is to restriction of the present utility model.Those of ordinary skills can make various variants on the basis of the embodiment that describes in detail under instruction of the present utility model, these variants all should be included within the design of the present utility model.This utility model scope required for protection is only limited by described claims.
