Abstract

The utility model belongs to a medical appliance, relating to a multi-direction drug ablation needle, comprising a sleeve (1) and an injection needle (2), which is characterized in that: the injection needle (2) is arranged in the sleeve (1), the part of the injection needle extending out of the sleeve is forniciform, a ruler (4) is arranged on a tube handle (3) of the sleeve, a positioning card (5) is covered on the tube body of the sleeve; the tube handle (3) is discoid, a ruler hole (9) is arranged on the tube handle (3), angles are marked on the disc, scales are marked on the tube body of the sleeve; the injection needle (2) comprises a needle tube (6) and a needle core (7), the handle parts of which are all provided with a bulge (8); and two groups of scales are marked on the ruler (4). The utility model has simple structure and convenient operation, can be led by CT or B ultrasonic, by a puncture, can more accurately and uniformly inject drug liquids into the whole region of the human knub, and is an ideal tool for ablating of knub drugs.

Description

Multidirectional medicine ablation needle

(1) technical field: this utility model relates to a kind of medical apparatus and instruments, particularly multidirectional medicine ablation needle.

(2) background technology: at present, when tumor is carried out the medicine ablation, generally under CT or B ultrasonic guiding, a straight long entry needle in skin thrusts tumor, is injected tumor with medicinal liquid, and medicinal liquid is trapped in injection point and the needle track scope, and diffusion towards periphery, the part medicinal liquid can spill into outside the internal organs along needle track, produces serious pain and breast or peritonitis, and the effective range of medicinal liquid diffusion is very limited and irregular.If tumor is carried out the multiple spot puncture for treating, not only waste time and energy, and influenced by puncture technique and site of puncture, be difficult to medicinal liquid is injected whole tumor region equably.

(3) utility model content: the purpose of this utility model is to provide a kind of under CT or B ultrasonic guiding, can medicinal liquid be injected into equably the multidirectional medicine ablation needle in the whole zone of human tumor through one-time puncture more accurately.

The purpose of this utility model is achieved in that this multidirectional medicine ablation needle, comprise sleeve pipe, entry needle, entry needle places in the sleeve pipe, and the part that entry needle stretches out outside the sleeve pipe becomes bending, on telescopic pipe handle, be equipped with a scale, cover one locator card on the sleeve pipe pipe shaft.

Described pipe handle is the garden plate-like, which is provided with a staff guage hole, and the garden dish is marked with angle, and the sleeve pipe pipe shaft is marked with scale.

Described entry needle is made up of needle tubing, nook closing member, and its shank is equipped with projection.

Described scale is marked with two groups of scales.

The beneficial effects of the utility model: simple in structure, easy to operate, use existing therapeutic device relatively, therapeutic effect and therapeutic efficiency all improve a lot.

(5) specific embodiment:

With reference to accompanying drawing, this utility model comprises a sleeve pipe 1, entry needle 2, and entry needle 2 places in the sleeve pipe 1, and the part that entry needle stretches out outside the sleeve pipe becomes bending, is equipped with a scale 4 on telescopic pipe handle 3, cover one locator card 5 on the sleeve pipe pipe shaft; Described pipe handle 3 is the garden plate-like, which is provided with a staff guage hole 9, and the garden dish is marked with angle, and the sleeve pipe pipe shaft is marked with scale; Entry needle 2 is made up of needle tubing 6, nook closing member 7, and its shank is equipped with projection 8; Scale 4 is marked with two groups of scales, shows that respectively the entry needle tip stretches out telescopic vertical and horizontal distance.During work, patient gets certain position, CT or B ultrasonic location, sterilization, local anaesthesia, cut point of puncture skin, sleeving core is put into sleeve pipe, CT or B ultrasonic guiding, sleeve pipe is thrust the inner edge of tumor axis, tighten the position that locator card is moved on to contact skin, withdraws from sleeving core, and entry needle is inserted sleeve pipe, set up scale, the entry needle needle point is inserted into the position of sleeve pipe front end, injects a certain amount of medicinal liquid that melts, drill drift pipe certain distance, unscrew locator card, move the location snap into the contact skin the position tighten again, entry needle is released from sleeve pipe, and is made its needle point reach borderline tumor, marginal not is penetrated medicinal liquid, entry needle is moved back on the limit, in the time of in entry needle retreats to sleeve pipe, and the revoling tube certain angle, once more entry needle is released sleeve pipe, and make its tip reach borderline tumor, so repeat, until medicinal liquid is injected whole tumor region equably.
