Abstract

A medical appliance used for CT-guided puncture location is composed of a medical operation film and hard plastic square strips, wherein, nine hard plastic square strips are parallel arranged and fixed on the medical operation film; a certain scale is formed between every two hard plastic square strips. When the medical appliance for CT-guided puncture location is used, a CT-guided puncture location device is arranged perpendicularly to a disinfected location zone in which the CT scanning line is stuck, and then a CT machine is arranged at the angle of zero degree. After the optimal puncturing point and the optimal focus are found in a CT image, a needle is inserted according to the scales and the angles of the CT-guided puncture location device. The utility model has the advantages of simple structure, easy operation and exact location.

Description

The CT puncture locator

Technical field

This utility model relates to a kind of medical apparatus and instruments, and a kind of more precisely CT puncture locator is mainly used in CT scan location, puncture point orientation.

Background technology

At present, the CT localized method that punctures is varied, multifarious.Usually mode is for using high-grade position finder or doing the localized simple and crude method of witness marker thing with metal, font 1, Gentian Violet etc.High-grade position finder costs an arm and a leg, and using method is loaded down with trivial details, and being not suitable for has certain limitation in the basic hospital penetration and promotion.There is very big shortcoming again in the normal simple and crude method of using of existing basic hospital: locator material is generally less, and coverage rate is little, can't disposable accurate localised puncture point, need repeatedly multiple scanning, and increased patient's roentgen radiation x dosage; Can't measure the puncture needle angle, can only be with operator's experience range estimation angle, error is bigger, and the operating time is long, easily increases patient's misery; Need remove telltale mark behind the location and sterilize once more, easily lose anchor point.

For overcoming the defective of prior art, the inventor has invented a kind of broad covered area, can once determine the CT localizer of best puncture anchor point, minimizing patient's roentgen radiation x dosage.This positioner system needle angle is convenient to the angle and the degree of depth that the operator holds inserting needle, can not lose point of puncture, stops second positioning.This utility model uses the deposited film of medical operation to be basic unit, and it is hemorrhage to reduce patient, prevents the pathogenic bacteria intrusion, reduces infection chance, and simple and convenient quick, safe and practical, the medical institutions that are suitable for any CT of having machine carry out the work.

Summary of the invention

It is expensive and use metal, font 1, Gentian Violet etc. to do the bigger problem of the localized simple and crude method error of witness marker thing that this utility model has solved existing localizer, has the characteristics of simple in structure, easy operating, accurate positioning.

The technical scheme that its technical problem that solves this utility model adopts is: apply several rigid plastics side's bars of parallel placement on the film at medical operation, every at a distance of totally nine of 1.0cm, every long 8cm, wide 0.1cm, high 0.5cm, printing precision on the medical deposited film between rigid plastics side's bar is the scale of 0.1cm.

During use directly with the CT puncture locator perpendicular to the CT scan line, stick on the localized skin of the needs of sterilizing, then the CT frame for " 0 " degree situation under scan positioning area.

The beneficial effects of the utility model are: simple in structure, easy operation, accurate positioning, the especially height of rigid plastics side's bar and scale marker have therebetween been known the entry point and the angle of puncture needle.

Description of drawings

Among the figure: the 1-medical operation applies film; 2-rigid plastics side bar; The 3-scale

The specific embodiment

Below in conjunction with accompanying drawing this utility model is explained:

As shown in Figure 1 and Figure 2, apply 9 the rigid plastics side's bars 1 that be arranged in parallel on the film 1 at medical operation, every plastic square bar 1 long 8cm, wide 0.1cm, high 0.5cm, at a distance of 1.0cm, printing precision on the medical deposited film between every rigid plastics side's bar 1 is the scale 3 of 0.1cm between the plastic square bar.

Directly the CT puncture locator is pasted during use and drafted a skin region (skin region is sterilized), put the CT frame then and be " 0 " degree perpendicular to the CT scan line.Connect a line after in the CT scan image, finding focus center and nearest rigid plastics side's bar 2 summits, regard a line as with body surface is approximate, do point of puncture with two line intersection points, can better simplyly calculate needed angle according to the scale 3 that CT puncture locator medical operation applies on the film.As when needs 90 are spent inserting needles, puncture needle is parallel to rigid plastics side's bar 2 and gets final product.After puncture is finished the CT puncture locator divested and get final product.

Claims

1, a kind of CT puncture locator applies film by plastic square bar and operation and constitutes, and it is characterized in that on the deposited film of a medical operation nine parallel rigid plastics side bars being set, and the deposited film between per two rigid plastics side's bars has the sign scale.

2, CT puncture locator according to claim 1 is characterized in that the rectangle medical operation applies film, long 10cm, wide 8cm, the wide 0.1cm of rigid plastics side's bar substrate, high 0.5cm, long 8cm.

3, CT puncture locator according to claim 1 and 2 is characterized in that between per two rigid plastics side's bars at a distance of 1.0cm, and deposited film therebetween has 0.1cm sign scale.
