Description

A kind of tumor micro-wound operation interventional therapy needle

Technical field

This utility model relates to technical field of medical instruments, specifically a kind of tumor micro-wound operation interventional therapy needle。

Background technology

Interventional therapy, is the emerging therapeutic method between surgery, medical treatment, treats including intravascular intervention and Non-vascularized iliac bone。Through the development of more than 30 years, three big pillar subjects it are called now together with surgery, internal medicine。Simply say, when interventional therapy is exactly do not operate on exposure focus, blood vessel, skin are made the minim channel of diameter several millimeters, or through the original pipeline of human body, the method for the treatment that the wound under the guiding of image documentation equipment (angiography machine, fluoroscopic machine, CT, MR, B ultrasonic), focus local treated is minimum。

Interventional therapy be characterized in wound little, easy, safely, effectively, few intercurrent disease and substantially shorten the hospital stays。Interventional therapy is in that with medical treatment advantage relatively: medicine can be done directly on diseased region, is not only greatly improved diseased region drug level, also can greatly reduce drug dose, reduces drug side effect；It is without operating on exposure focus, the general skin incision only needing several millimeters, so that it may completing treatment, epidermis injury is little, specious；As long as most patients local anesthesia but not general anesthesia, thus reducing the danger of anesthesia；Damage little, recover fast, good results, the impact of health normal organ is little；For the malignant tumor that treatment difficulty is big, 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。

When carrying out tumor intervention therapeutic to patient more clinically, tradition insertion puncture needle comprises syringe needle, needle body and needle handle, and after syringe needle thrusts blood vessel, seal wire penetrates via needle handle；Existing needle handle is shorter, and it can cause seal wire to penetrate the unstability of process, it is difficult to controls the degree of depth of thrusting of seal wire, easily spills a large amount of blood simultaneously, it is easy to cross infection occurs；Meanwhile, existing puncture needle is when puncturing, it does not have fixation means, makes troubles to whole piercing process；And the site of puncture of existing puncture needle also easily oozes out the liquid such as blood or medicinal liquid, is susceptible to cross infection equally。
