Abstract

The utility model belongs to medical instruments and relates to a medicine ablating needle which comprises a sleeve (1) and an injection needle (2). The medicine ablating needle is characterized in that the injection needle (2) is arranged in the sleeve (1), a part of the injection needle, extending out of the sleeve, is bent, a ruler (4) is arranged on a sleeve handle (3) of the sleeve, a positioning clamp (5) is arranged on a sleeve body of the sleeve, the sleeve handle (3) is in a disc shape, a ruler hole (9) is arranged in the sleeve handle (3), angles are marked on the disc, scales are marked on the sleeve body of the sleeve, the injection needle (2) consists of a needle tube (6) and a needle core (7), bulges (8) are arranged at handle parts of the injection needle, and two groups of scales are marked on the ruler (4). The medicine ablating needle is simple in structure, is convenient to operate, and can more accurately inject medicine liquid into the whole area of a tumour of a human body uniformly under the guidance of CT (computed tomography) or B-ultrasound by puncturing once, thus being an ideal tool for ablating tumour medicine.

Description

A kind of medicine ablation needle

(1) technical field: this utility model relates to a kind of medical apparatus and instruments, particularly a kind of 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 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 medicine ablation needle, comprises sleeve pipe, entry needle, and entry needle places in the sleeve pipe, and the part that entry needle stretches out outside the sleeve pipe becomes to become curved, on telescopic pipe handle, is equipped with a scale, cover one locator card on the sleeve pipe pipe shaft.

Said pipe handle is in the form of annular discs, which is provided with a staff guage hole, and disk is marked with angle, and the sleeve pipe pipe shaft is marked with scale.

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

Said scale is marked with two groups of scales.

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

Among the figure: the 1-sleeve pipe, the 2-entry needle, 3-manages handle, the 4-scale, the 5-locator card, the 6-needle tubing, the 7-nook closing member, 8-is protruding, the 9-staff guage hole.

(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, on telescopic pipe handle 3, is equipped with a scale 4, cover one locator card 5 on the sleeve pipe pipe shaft; Said pipe handle 3 is in the form of annular discs, which is provided with a staff guage hole 9, and disk 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 protruding 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, and sterilization, local anaesthesia, incision point of puncture skin are put into sleeve pipe with sleeving core; The guiding of CT or B ultrasonic is thrust the inner edge of tumor axis with sleeve pipe, and tighten the position that locator card is moved on to contacting 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, inject a certain amount of medicinal liquid that melts, drill drift pipe certain distance; Unscrew locator card, move the position that the location snaps into contacting skin and tighten again, entry needle is released from sleeve pipe, and made its needle point reach borderline tumor; Marginal not is penetrated medicinal liquid, and 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.
