Description
Technical field
This utility model relates to medical surgical instrument technical field, particularly a kind of Internal Medicine-Oncology interventional therapy needle.
Background technology
Interventional therapy (Interventional treatment) is the emerging therapeutic method between surgery, medical treatment, comprises intravascular intervention and Non-vascularized iliac bone treatment.Through the development of more than 30 years, three large pillar subjects are called now together with surgery, internal medicine.Simply say, interventional therapy is exactly when not operating on exposure focus, blood vessel, skin are done the minim channel of diameter several millimeters, or through the original pipeline of human body, to the method for the minimum treatment of the focus local wound for the treatment of under the guiding of image documentation equipment (angiography machine, fluoroscopic machine, CT, MR, B ultrasonic).
Interventional therapy is characterized in that wound is little, easy, safe, effective, few intercurrent disease and obviously shorten the hospital stays.Interventional therapy is relatively with medical treatment advantage: medicine can directly act on diseased region, not only can greatly improve diseased region drug level, also can greatly reduce drug dose, minimizing drug side effect; It is without the need to operating on exposure focus, the general skin incision only needing several millimeters, just can completed treatment, and epidermis injury is little, specious; As long as most patients local anesthesia but not general anesthesia, thus reduce the danger of anesthesia; Damage little, recover fast, good results, little on the impact of health normal organ; For the malignant tumor that treatment difficulty is large, interventional therapy can be confined to medicine the position of pathological changes as far as possible, and reduces the side effect to health and other organs.Partial tumors is equivalent to surgical excision at PTCA or and STENTS.
Just due to above plurality of advantages, many interventional therapy methods are becoming one of some diseases (as: liver cirrhosis, hepatocarcinoma, pulmonary carcinoma, prolapse of lumbar intervertebral disc, aneurysm, vascular malformation, hysteromyoma etc.) topmost Therapeutic Method.Comparatively conventional have use puncture needle directly through body puncture to the Therapeutic Method of focus feeding artery.
The usual more common entry needle of puncture needle is long, and the inserting needle smoothness in piercing process can be influenced, and the hand steered syringe needle puncture of operator easily cross infection occurs.
Utility model content
This utility model provides a kind of Internal Medicine-Oncology interventional therapy needle, selects the inclined-plane of the different angles of trapezoidal sleeve pipe to puncture during puncture according to the requirement of puncture angle, easy to use, improves puncture accuracy and work efficiency.
For achieving the above object, this utility model have employed following technical scheme:
Internal Medicine-Oncology interventional therapy needle of the present utility model, comprise puncture needle and the straight pipe of connection, puncture needle and straight pipe junction are socketed with needle handle and needle stand, needle handle and needle stand have the through hole being communicated with straight pipe and puncture needle, also comprise trapezoidal sleeve pipe, connect puncture needle and needle handle, trapezoidal sleeve pipe entirety is hollow round table structure, casing profile is prismatoid, and prismatoid its tapering in section is by 15 ° to 35 ° even transition.
As perfect further, bushing outer surface has some the straight lines extended along sleeve pipe trapezoidal inclined plane, angulation line, angle line end angular dimension value.
Compared with prior art, the beneficial effects of the utility model are:
1) be aided with trapezoidal sleeve pipe determination puncture angle during puncture, make puncture position more accurate, directly arrive affected area, avoid maloperation, improve success rate and the work efficiency of puncture.
2) tapering of Internal Medicine-Oncology interventional therapy needle is by 15 ° to 35 ° even transition, can select the auxiliary puncture of the conical surface of different angles as required, be applicable to the operation requirements of different demand.
3) bushing outer surface has some the straight lines extended along trapezoidal inclined plane, and angulation line, the tapering angular dimension corresponding according to angle line position, angle is intuitively visual.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of Internal Medicine-Oncology interventional therapy needle of the present utility model.
In figure: 1. puncture needle; 2. needle handle; 3. needle stand; 4. straight pipe; 5. sleeve pipe; 6. angle line.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in further detail.
Embodiment 1
See accompanying drawing 1, Internal Medicine-Oncology interventional therapy needle of the present utility model, comprise puncture needle 1 and the straight pipe 4 of connection, puncture needle 1 and straight pipe 4 junction are socketed with needle handle 2 and needle stand 3, and needle handle 2 has with needle stand 3 through hole being communicated with straight pipe 4 and puncture needle 1, also comprise trapezoidal sleeve pipe 5, connect puncture needle 1 and needle handle 2, trapezoidal sleeve pipe 5 entirety is hollow round table structure, and sleeve pipe 5 cross section is prismatoid, and prismatoid its tapering in section is by 15 ° to 35 ° even transition.
As perfect further, sleeve pipe 5 outer surface has some the straight lines extended along sleeve pipe 5 trapezoidal inclined plane, angulation line 6, angle line 6 end angular dimension value.
Be aided with trapezoidal sleeve pipe 5 during puncture and determine puncture angle, make puncture position more accurate, directly arrive affected area, avoid maloperation, improve success rate and the work efficiency of puncture.
The tapering of Internal Medicine-Oncology interventional therapy needle, by 15 ° to 35 ° even transition, can be selected the auxiliary puncture of the conical surface of different angles as required, be applicable to the operation requirements of different demand.
Sleeve pipe 5 outer surface has some the straight lines extended along trapezoidal inclined plane, and angulation line 6, the tapering angular dimension corresponding according to angle line position, angle is intuitively visual.
