Abstract

The utility model relates to a novel CT guided puncture localizer, which belongs to the field of medical instruments and comprises a locating plate 1, a U-shaped plate 2 and a protractor 3. The novel CT guided puncture localizer is characterized in that the radian of the locating plate 1 is consistent with that of a CT examination couch, the locating plate 1 is provided with twenty-four imaging tubes 4 marked with numerical codes, and the spacing of each two imaging tubes 4 is 1 centimeter. Two sides of the locating plate 1 are provided with sliding grooves 5, a U-shaped track 6 is arranged on the U-shaped plate 2 and a rotating shaft 7 is arranged on the protractor 3. Two ends of the U-shaped plate 2 can move forwards and backwards on the sliding grooves 5, and the protractor 3 can move on the U-shaped track 6 through the rotating shaft 7. The novel CT guided puncture localizer is an ideal one due to the facts that the localizer is simple in structure, convenient to use and capable of accurately setting a puncturing point and a puncturing angle.

Description

The new CT guide puncture position finder

Technical field: this utility model belongs to medical instruments field, particularly a kind ofly can accurately make point of puncture and puncture angle, new CT guide puncture position finder simple in structure, easy to use.

Background technology: along with the extensive use of CT technology in the clinical treatment activity, the application of CT ultrasonic puncture art is also more and more, this paracentetic key is to make an accurate selection of point of puncture and the puncture direction and the degree of depth, is mainly used in the intravital tumor of patient is got the inspection chemical examination or intravital hydrops pneumatosis is carried out discharge opeing venting etc.At present, clinical widely used method is to determine entry point and puncture angle according to CT scan figure, in piercing process, the main position of feeling to determine the puncture needle place that relies on range estimation and patient, the angle and the degree of depth, but often because the range estimation deviation, the location is inaccurate, operant level, clinical experience, reasons such as judgement, cause the inserting needle deviation, thereby need to adjust angle, puncture once more, increased the inserting needle number of times, bring unnecessary loss and misery to the patient, if focus is positioned at around patient's splanchnocoel important organ or the trunk, puncture locatees not that the brigadier brings life danger to the patient.

Summary of the invention: the purpose of this utility model is to provide a kind of can accurately make point of puncture and puncture angle, new CT guide puncture position finder simple in structure, easy to use.

For achieving the above object, this utility model has been taked following technical scheme: this new CT guide puncture position finder, constitute by location-plate, U-shaped plate and protractor, the radian of location-plate is consistent with the radian of CT examination bed, and location-plate is provided with 24 and indicates digital development pipe, spacing between every development pipe is 1cm, the both sides of location-plate are provided with chute, the U-shaped plate is provided with U-rail, protractor is provided with rotating shaft, the two ends of U-shaped plate can be moved front and back on chute, and protractor can move on U-rail by rotating shaft.

This utility model, simple in structure, easy to use, can accurately make point of puncture and puncture angle, be a kind of ideal CT guide puncture position finder.

Description of drawings: the utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

With reference to accompanying

drawing
