Abstract

The utility model relates to a health treatment trocar for use in blood vessel for clinical application. The utility model is composed of an intravenous infusion needle and a laser needle inserted in a pinhole. The laser needle is composed of a needle head, a needle handle and optical fiber of an inner hole of the needle head. The utility model has the advantages of simple structure, easy use and safety. The infusion treatment can be carried out once. Patients are willing to accept the utility model. Nurses can use the utility model with high proficiency.

Description

Health treatment trocar for use in blood vessel

This utility model relates to the invalid endovascular treatment health care of treatment trocar on a kind of clinical medicine.

In blood vessel, be important a kind of means clinically, as being exactly one of them in endovascular treatment with the helium-neon laser remaining needle to disease position treatment.Along with science and technology development, it is more and more to produce He-Ne laser inner blood vessel internal therapy device in recent years, but when treating, be the remaining needle that adopts a kind of external import mostly, this indwelling syringe needle is thick (diameter 0.9mm), overcoat plastic tube thicker (diameter 1.2mm) in use, is gone into plastic tube the blood vessel from the patient table prickle with syringe needle, then syringe needle is dialled, plastic tube is retained in the blood vessel, again with laser needle along plastic tube inner chamber intravasation, treat, this remaining needle is because puncture needle is thick, and be with plastic tube outward, very bitterly, patient is difficult for accepting when puncture, particularly the old man fears, child's blood vessel is thin, more can't use, and effect is not good enough.

The purpose of this utility model is exactly the actual needs at above-mentioned situation and patient, and a kind of novel endovascular treatment health care trocar is provided.

The purpose of this utility model is achieved like this: utilize existing venoclysis needle, penetrate a fibre-optic metal needle of center band in venoclysis needle syringe needle hole, syringe needle is connected with the joints of optical fibre through needle handle.

This utility model is simple in structure, and is easy to use, and the many usefulness of a pin both can be used as transfusion, can be used as endovascular treatment again, and patient is easy to accept, and has great popularizing value.

Below in conjunction with accompanying drawing structure of the present utility model and operating position usefulness are described in detail.

Structure chart of the present utility model on Fig. 1.

Fig. 2, the 3rd, the structure chart of this utility model laser needle.

Shown in Fig. 1-3, this utility model is to be made of venoclysis needle 2 and laser needle 1.The infusion tube cover of laser needle 1 through venoclysis needle 2 rear portions is inserted in the pin hole of venoclysis needle 2, laser needle 1 is to be made of optical fiber 3, syringe needle 4, reducing step needle handle 5, optical fiber 3 is contained in the hole, garden of syringe needle 4, the two by the KD504 adhesive glue together, needle handle 5 is equipped with at the rear portion of syringe needle 4.Optical fiber 3 is pure quartz fiber optics, and this fiber transmission attenuation is few, has the good optical performance, bigger numerical aperture, and syringe needle 4 is made by stainless steel capillary, and the front end needle point of syringe needle 4 is a knob, prevents to stab blood vessel wall; For the ease of being connected with the joints of optical fibre, guarantee good to neutrality and proper alignment, needle handle 5 is step-like, stainless steel capillary (as φ 2.5, φ 1mm) by the multilamellar different-diameter is nested together, connect firmly (seeing shown in Figure 2) with glueing joint, needle handle also can be connected firmly by the tubule and the splicing of syringe needle 4 capillary tubies of other metals, and then becomes the step needle handle 5(of different-diameter to see Fig. 3 through machining).Needle handle rear end face mill is polished to minute surface.As required, this utility model can steam, boils and soak in different disinfectant solution, disinfects.The syringe needle of laser needle 1 should expose venoclysis needle front end (being that syringe needle 4 slightly is longer than intravenous infusion syringe).

Operating position of the present utility model is, earlier transfusion needle 2 is thrust in the vein blood vessel by the transfusion routine, venous transfusion in advance, because the critical patient is often with infusion process, after the transfusion, the infusion tube that laser needle 1 is passed venoclysis needle 2 rear portions inserts in the pin hole of venoclysis needle, and making syringe needle expose intravenous infusion syringe, needle handle 5 is connected with the joints of optical fibre, just can operate therapeutic instrument and carry out work (treatment).

From the above, this utility model is easy to use, and is simple to operate, safe and reliable, infusion treatment can once carry out, but also blood vessel is played health-care effect, ill curing the disease, anosis diseases prevention, patient takes like a shot, the nurse is handy, and it is applied and must be subjected to patient and medical personnel's welcome deeply, produces good effect.
