Abstract

The utility model discloses a kidney puncture needle which comprises a needle base and a needle body. The kidney puncture needle is characterized in that scale marks are arranged on the outer wall of the needle body; an annular ultrasonic reflection band is fixed on the inner wall of the front end of the needle body close to the needle tip; a fixing sleeve which is capable of sliding along the axial direction of the needle body is sheathed outside the needle body; and a fastening screw is arranged on the fixing sleeve. Compared with the prior art, the kidney puncture needle is simple in structure, convenient in use and effectively controllable in puncture depth; and under ultrasounds, the needle, kidneys and surrounding tissues can be clearly separated by the ultrasonic reflection band, so that the puncture positioning is accurate, the work strength of medical personnel can be greatly lightened and the work difficulty is reduced.

Description

A kind of kidney puncture needle
Technical field
This utility model relates to a kind of medical apparatus, specifically, relates to a kind of kidney puncture needle.
Background technology
The renal puncture biopsy is a kind of important method of Diagnosis of Renal disease, and generally speaking, the Urology Department doctor can use by rule of thumb that kidney puncture needle is blind to be worn, and universal day by day along with ultrasonic instrument, it is then more accurate under ultrasonic guidance, to carry out renal puncture.
Existing common puncture needle has following defective: when 1, puncturing, puncture needle is thrust, depth of needle will be used ruler measurement repeatedly, makes troubles influence puncture quality to operation; 2, when puncture, measured paracentesis depth after, be fixed on the puncture needle with finger, to confirm the puncture needle depth of needle, move, and influence the accuracy of paracentesis depth but be prone to finger in the operating process; 3, common puncture needle is very unintelligible in ultrasonic following projection, is difficult to distinguish with kidney and surrounding tissue, and it is inaccurate that the site of puncture is confirmed, this has just increased work difficulty to the medical personnel.
Summary of the invention
The technical problem that this utility model will solve is to overcome above-mentioned defective, provides a kind of and can accurately control paracentesis depth and under ultrasonic, can clear syringe needle and kidney and surrounding tissue be separated the kidney puncture needle of puncture accurate positioning.
For addressing the above problem, the technical scheme that this utility model adopted is:
A kind of kidney puncture needle comprises needle stand and needle body, it is characterized in that: the outer wall of said needle body is provided with graduation mark; At the front end of needle body, on the inwall near the needle point position, be fixed with cyclic ultrasonic reflections band; Needle body sleeve has can be along needle body fixed cover in axial sliding, and fixed cover is provided with trip bolt.
Owing to adopted technique scheme, compared with prior art, this utility model is simple in structure, easy to use; Can effectively control paracentesis depth; Under ultrasonic, the ultrasonic reflection band can clearly separate syringe needle and kidney and surrounding tissue, the puncture accurate positioning; Can alleviate medical worker's working strength greatly, reduce work difficulty.
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described further.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of this utility model.
The specific embodiment
Embodiment:
A kind of kidney puncture needle shown in accompanying drawing, comprises needle stand 1 and needle body 5.The outer wall of said needle body 5 is provided with graduation mark 4.At the front end of needle body 5, on the inwall near the needle point position, be fixed with cyclic ultrasonic reflections band 6.Needle body 5 is outer, and be with can be along needle body 5 fixed cover 2 in axial sliding.Fixed cover 2 is provided with trip bolt 3.
