Abstract
The utility model relates to a CT (computed tomography) guided puncture positioner which comprises a positioning plate, a U-shaped plate and an angle measuring plate, wherein the radian of the positioning plate is consistent with the radian of a CT examination bed, the two sides of the positioning plate are respectively provided with a sliding chute, the U-shaped plate is slidably connected with the positioning plate through the sliding chutes, the U-shaped plate is provided with a U-shaped rail, the angle measuring plate is horizontally arranged in the U-shaped rail and moves along the U-shaped rail, a fixing device is arranged in the U-shaped rail, the positioning plate is provided with a developing tube, the sliding chute is slidably connected with a telescopic rod, the upper end of the telescopic rod is provided with a hook, the angle measuring plate can be moved randomly to all sides, even if puncture points are located at different positions of the body, the angle measurement can be performed conveniently by using the angle measuring plate, and meanwhile, through drawing a telescopic pointer, the telescopic pointer is closer to a puncture point, so that the measurement is more accurate. The CT guided puncture positioner disclosed by the utility model is simple in structure and easy to use, and can accurately determine puncture points and puncture angles, thereby improving the success rate of CT guided puncture.
Description
Technical field
This utility model relates to the medical instruments technical field, specifically, relates to a kind of CT guide puncture position finder.
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 puncture direction and the degree of depth, is mainly used in the tumor in patient body is got the inspection chemical examination or the hydrops pneumatosis in body 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, main position, angle and the degree of depth of feeling to determine the puncture needle place that relies on range estimation and patient, but often because estimate deviation, the location is inaccurate, operant level, clinical experience, the reasons such as judgement, cause the inserting needle deviation, thereby need to adjust angle, again puncture, increased the inserting needle number of times, bring misery to patient, increased the probability of complication.For some patients, this error may be fatal.
The utility model content
The technical problems to be solved in the utility model is for above deficiency, and a kind of simple in structure, easy to use, the CT guide puncture position finder that can accurately make point of puncture and puncture angle is provided, and has improved CT ultrasonic puncture success rate.
In order to solve above technical problem, the technical solution adopted in the utility model is as follows: a kind of CT guide puncture position finder, comprise location-plate, U-shaped plate and Angle protractor, location-plate has radian, the both sides of location-plate are provided with chute, the U-shaped plate is slidably connected by chute and location-plate, U shape plate is provided with U-rail, Angle protractor is horizontally set in U-rail and moves along U-rail, be provided with fixture in U-rail, location-plate is provided with the pipe that develops, and chute slidably connects expansion link, and the expansion link upper end is provided with hook.
As further improvement in the technical proposal:
Described fixture comprises screw bolt and nut.
Described Angle protractor is provided with flexible pointer.
Described location-plate is provided with 20 equally distributed development pipes.
Spacing between described every development pipe is 1.5cm.
this utility model is taked above technical scheme, have the following advantages: the CT guide puncture position finder comprises location-plate, U-shaped plate and Angle protractor, the radian of location-plate is consistent with the radian of CT examination bed, the both sides of location-plate are provided with chute, the U-shaped plate is slidably connected by chute and location-plate, U shape plate is provided with U-rail, Angle protractor is horizontally set in U-rail and moves along U-rail, be provided with fixture in U-rail, location-plate is provided with the pipe that develops, chute slidably connects expansion link, the expansion link upper end is provided with hook, can be all around random amount of movement gusset, even point of puncture is different local health, can carry out angular surveying with Angle protractor easily, simultaneously, flexible pointer stretches, to stretch pointer more near point of puncture, it is more accurate to measure, this utility model is simple in structure, easy to use, can accurately make point of puncture and puncture angle, improved CT ultrasonic puncture success rate.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is the structural representation of CT guide puncture position finder in this utility model embodiment.
