Abstract

The utility model relates to a CT positioning puncture plate, and consists of a fixing plate (1), coarse developing pipes (2) and thin developing pipes (3). The utility model is characterized in that the fixing plate (1) is a quadrate soft plate, and the thin developing pipes (3) are glued on the fixing plate (1) along O1 to X direction in an isometry manner, and the coarse developing pipes (2) are glued along the O to X direction in an isometry manner, and along O1 to Y direction in an equidifferent descending manner. The upper ends for the coarse and thin developing pipes (2, 3) are in a beeline, and are piled with the upper edge of the fixing plate 1. The CT positioning puncture plate has the advantages of simple structure, convenient use and exact positioning; thereby the utility model can be widely used in the CT guide puncture technique.

Description

CT localised puncture plate

This utility model relates to a kind of CT localised puncture device, and specifically a kind of CT localised puncture plate is applicable to CT guided puncture technology.

Along with the CT technology in medically extensive use, the CT guided puncture technology of numerous disease is used more and more, the key of this puncture technique is to make an accurate selection of point of puncture and the puncture direction and the degree of depth, general by the clinical experience grasp, operating difficulty is bigger, positional accuracy is not high, influences patient's timely and effective treatment; Employing CT image tape measure method that also has and body surface point-like mark placement methods location.Diseased region CT image tape measure method location, usually factor causes Body Position Change in the CT scan process and reduces accuracy because timebase is inaccurate or patient is restless etc.; Body surface point-like mark placement methods positional accuracy is higher relatively, not only waste time and energy but operate, and can only carry out at CT Room and CT machine free time, its sterile working often is subjected to the restriction of objective condition, and still there is unfavorable factor in patient to the staff of CT Room.At present, domestic high-precision brain solid positioner tentatively is used for clinical, this position finder is to adopt certain any three-dimensional positioning principle, find out the relative structure that limits of an anatomical position earlier as the location initial point, measure the numerical value of intracranial impact point by these three mutually perpendicular planes of initial point design then at three-dimensional coordinate, thereby determine the target location, the shortcoming of this position finder is the application process complicated operation, time is long before the art, apply difficulty, especially to critical patient and unconsciousness patient or the short patient of cervical region, operation is difficulty quite, and the equipment price height, application has certain limitation.

The purpose of this utility model is to provide a kind of simple in structure, accurate positioning, easy to use, time saving and energy saving, the CT localised puncture plate of reducing expenses, not only be used for the puncture location of head pathological changes, and can be used for the puncture location of chest and extremity position pathological changes.

This utility model is achieved in that this CT localised puncture plate, by fixing head, the thick pipe that develops, carefully the pipe that develops constitutes, its fixing head is the rectangle soft board, make of nonvisualized plastics or rubber, fixing head upper edge O '-directions X by equidistant the stickup on the thin pipe that develops, and simultaneously along O '-directions X by equidistant, successively decrease to paste by equal difference along O '-Y direction and go up the thick pipe that develops, slightly, carefully develop pipe the upper end point-blank, and overlap with the upper edge of fixing head, the pipe that slightly, carefully develops can be made of useless interposing catheter.The length of fixing head is 12-16cm, and width is 10cm, and 11 of Guan Gongshe carefully develop, its length is 10cm, consistent with the width of fixing head, the distance between the adjacent thin development pipe is 1cm, promptly establishes one every 1cm, thick development tube side-by-side sticks on the position of thin development pipe, the upper end is concordant, and the bottom of adjacent thick development pipe differs 1cm, and successively decreases successively, the diameter of thin development pipe is 0.1cm, and the diameter of the pipe that slightly develops is 0.15cm.When application this utility model carries out the puncture of cranium brain, with crayon at patient's the temples timebase OM that draws, O is a porus acusticus externus, with the O ' on the fixing head aligning porus acusticus externus, O '-X is overlapped with OM, be about to fixing head and place patient's temples, temples is more flat, fixing easily, with elastic band fixing head is fixed on patient's head, can carry out head scanning; Localization method is: according to scanned picture, select the aspect with optimum puncturing point, go out selected aspect body surface characteristic development pipe ordinal number along O '-directions X number, can select the coordinate of optimum puncturing point on fixing head; Contain thickness development pipe sign shadow " O on the selected aspect." number to subtract 1 promptly be the coordinate of this point of puncture in O '-Y direction, selected aspect is " O on O ' directions X." or "." to subtract 1 promptly be coordinate on the point of puncture O ' directions X for the ordinal number of shadow, the pairing body surface of this coordinate position promptly is a point of puncture.

The utility model has the advantages that: compare with existing C T puncture locator tool, not only simple to operate, time saving and energy saving, accurate positioning, and making is easy, price is low, not only can be used for craniopathia set position, and can be used for the puncture location of other position pathological changes of health.Owing to chosen the body surface point of puncture in advance, be not subjected to the restriction of when and where relatively; Owing to adopted the body surface setting-out to overlap with the plate base of puncturing, make that CT scan needn't begin from the bottom just directly to scan from point of puncture roughly, both saved time, reduce expenses again.Adjust voluntarily after measuring according to selected aspect as for puncture angle and depth visual situation, to obtain optimum efficiency.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 looks sketch map for this utility model master.

Fig. 2 is that this utility model is along A-A section cross-sectional schematic.

Make this utility model with reference to accompanying drawing 1,2.This CT localised puncture plate, constitute by fixing head 1, the thick pipe 2 that develops, the thin pipe 3 that develops, fixing head 1 is the rectangle soft board, make of nonvisualized plastics or rubber, go up the thin pipe 3 that develops at fixing head 1 upper edge O '-directions X by equidistant the stickup, and simultaneously along O '-directions X by equidistant, successively decrease to paste by equal difference along O '-Y direction and go up the thick pipe 2 that develops, the upper end of thick, the thin pipe 2,3 that develops is point-blank, and overlap with the upper edge of fixing head 1, thick, the thin pipe 2,3 that develops can be made of useless interposing catheter.The length of fixing head 1 is 12-16cm, width is 10cm, and the thin pipe 3 that develops is established 11 altogether, and its length is 10cm, consistent with the width of fixing head 1, distance between the adjacent thin development pipe 3 is 1cm, and the thick pipe 2 that develops sticks on the position of thin development pipe 2 side by side, and the upper end is concordant, the bottom of adjacent thick development pipe 2 differs 1cm, and successively decrease successively, the thin diameter that develops pipe 3 is 0.1cm, the thick diameter that develops pipe 2 is 0.15cm.
