CN2647246Y - Side crypt punching needle and coordinate positioning film - Google Patents

Abstract

The utility model relates to a side recess puncture needle and coordinates positioning film, comprising a puncture needle and a coordinate positioning film, which is characterized in that the puncture needle constituted by the needle tube and the needle core is radius; the coordinate line is arranged on the coordinate positioning film which is displayed under the x ray. The utility model not only effectively protects the nerve sleeve against breaking and ensures successful puncture but also quickly and accurately locates the puncture location. At the same time, the utility model has the advantage of rational design, simple operation and low cost.

Description

Side crypts puncture needle and coordinate setting film

Technical field

This utility model relates to a kind of medical thrust apparatus, exactly is a kind of puncture needle and coordinate setting film of side crypts puncture injection pharmaceutical treatment prolapse of lumbar intervertebral disc.

Background technology

Existing various needle set is asks needle point sharp keen, so that puncture.At present in side crypts puncture injection collagenase treatment prolapse of lumbar intervertebral disc process, employing be the puncture needle of sharp keen needle point, touch the body surface location or adopt the position finder location with hands with doctor's experience.Like this, sharp keen needle point is worn out the neural sleeve of following easily, causes puncture failure, also can cause nerve injury simultaneously.Moreover, above-mentioned locate mode, the former accuracy is not good enough, and the latter not only operates cumbersome but also cost is high.

This utility model content

The purpose of this utility model is to provide a kind of at above-mentioned defective can prevent effectively that side crypts piercing process is neural to be caused the latent puncture needle of side of puncture failure with the sleeve damage and can accurately locate and coordinate setting film easy and simple to handle.

This utility model comprises puncture needle and coordinate setting film, it is characterized in that:

A, the pricker syringe needle of threading a needle that is made of needle tubing and nook closing member are circle obtuse;

Be placed with coordinate line on b, the coordinate setting film that can under X-ray, develop.

In addition, coordinate line is rectangular coordinate line or polar coordinate line.

During operation, the coordinate setting film that can develop under X-ray is affixed on patient's lumbar intervertebral disc affected part, search out the subpoint of side crypts rapidly and accurately by X-ray at body surface, determine to puncture, locate with a common syringe needle behind the puncture position, this syringe needle of reuse is the lancet puncture injection medicament treatment of circle obtuse.

This utility model effect

1, this utility model adopts circle indenting ball lancet puncture, and neuroprotective is not the worse for wear with sleeve effectively, thereby guarantees to puncture successfully.Simultaneously, can effectively avoid nerve injury.

2, with coordinate setting film location, can determine puncture position rapidly and accurately.

3, this utility model is reasonable in design, and is easy and simple to handle, with low cost.

The specific embodiment

Embodiment 1:

(referring to Fig. 1,2), this utility model comprise puncture needle 1 and coordinate setting film 2, and the syringe needle 5 of the puncture needle 1 that is made of needle tubing 3 and nook closing member 4 is processed into circle obtuse.Adopt iopanoic acid or barium agent to be made into and on the coordinate setting film 2 that develops under the X-ray, to be placed with coordinate line 6 as host.(referring to Fig. 3,4), coordinate line are rectangular coordinate line or polar coordinate line.

Claims (2)

1, a kind of side crypts puncture needle and coordinate setting film comprise puncture needle and coordinate setting film, it is characterized in that:

A, the puncture needle syringe needle that is made of needle tubing and nook closing member are circle obtuse;

Be placed with coordinate line on b, the coordinate setting film that can under X-ray, develop.

2, side crypts puncture needle according to claim 1 and coordinate setting film is characterized in that: coordinate line is rectangular coordinate line or polar coordinate line.
