Abstract
The present invention discloses a CT guide puncture position finder, consisting of holding device, angle-measuring device and base seat. The holding device includes an inverted U-shaped plate, an U-shaped slideway passing through the plate, and a square plate equipoped respectively at the bottom ends of two sides of the U-shaped plate. The undersurface of the square plate is coated with magic glue. The angle-measuring device includes an inverted protractor, metal pointer and forward and backward screws with same axle centre, and its base seat is made into a curved hard plate, its radian is identical to that of CT bed, and two sides of said base seat respectively are coated with a strip of magic glue, and then the U-shaped plate can be fixed by means of cohesion of the above-mentioned magic glues. It can accurately define puncture point and puncture angle.
Description
The present invention relates to a kind of instrument of the CT of being used for ultrasonic puncture operation.
Existing CT ultrasonic puncture operation, the medical worker is according to entry point of making on the CT scan figure and needle angle, on human body, determine entry point and needle angle then with naked eyes and experience, but often because of the range estimation deviation, the operating technology level, judgement, reasons such as patient's cooperation cause the inserting needle deviation, thereby need to adjust angle, puncture again, increased the inserting needle number of times, complication increases thereupon, under the situation that especially swollen thing is positioned at around the chest abdomen viscera trunk, the position is dark, volume is little, puncture is dangerous to be increased, and puncture success rate also descends.
When the object of the present invention is to provide a kind of CT guiding to descend puncture procedure, can accurately make point of puncture and puncture angle and easy to operate CT guide puncture position finder.
CT guide puncture position finder provided by the invention is made of clamping device, angle measurer and base, and wherein angle measurer is contained on the clamping device, and clamping device is arranged on the base.
Clamping device of the present invention comprises an inverted U template, is penetrated with a U type chute on the U template; The bottom, both sides of U template is respectively equipped with a square plate, and the square plate bottom surface is with magic glue.Be provided with a fixture in the chute of the present invention, fixture comprises screw bolt and nut, and screw bolt and nut can be fixed in the chute on arbitrary position, with this prevent the U template because of the two parts up and down that are provided with chute and form take place before and after dislocation.
Angle measurer of the present invention comprises inverted protractor, metal finger and has positive and negative two screws in same axle center, wherein the axle center is provided with a catch, catch and axle center are perpendicular, protractor and metal finger are enclosed within the both sides of axle center upper stop piece respectively, be tightened respectively on chute with positive and negative screw, angle measurer can according to patient's actual lesion position different and in chute stepless being free to slide.Metal finger is different in size, with fat or thin replaceable 10～30cm plurality of specifications of patient.Screw is under loose situation, and the metal finger freedom is sagging, thereby determines the vertical line of protractor, and according to the site of the angle of determining on the CT machine, can anaesthetize and puncture in the angle and the site of reserving pointer again.
Base of the present invention is an arc hardboard, its arc degree is consistent with the CT bed, be respectively with a strip magic glue on the base dual-side, by with bottom, U template both sides square plate on the magic glue bond fix the U template, can move up and down the U template according to patient's actual lesion position difference in case of necessity and be adhesively fixed; Base is provided with several " one " font holes again, is installed with in the hole in order to fixing patient's fixing band.
The a whole set of instrument of the present invention is except that pointer is made by metal material, and other device is all made by nonmetallic materials, as plastics, lucite or timber etc.The present invention can free in and out the CT portal frame and can disinfect repeatedly.During use, base is placed on the CT lathe, on patient lay, CT scan was made the inserting needle site, and the utilization angle apparatus is made actual inserting needle circuit, and scanning is examined once more, can puncture.
In sum, the present invention have simple in structure, can accurately make point of puncture and puncture angle and easy to operate, practical characteristics.
The present invention is further illustrated below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the STRUCTURE DECOMPOSITION sketch map of angle measurer of the present invention.
As shown in Figure 1, 2, CT guide puncture position finder of the present invention is made of clamping device 1, angle measurer 2 and base 3.Wherein clamping device 1 comprises an inverted U shape flitch 4, is penetrated with a U type chute 5 on the plate, is provided with a fixture in the chute 5, and fixture is made up of a plastic bolt 8 and nut 9, can be fixed in the chute 5 on arbitrary position.The bottom, both sides of U shape flitch 4 is respectively equipped with a square thick plastic plate 6, and the bottom surface of square plate 6 is with magic glue 7.Angle measurer 2 comprise inverted protractor 10, metal finger 11 and have positive and negative two screws 13,13 in same axle center 12 ', wherein axle center 12 is provided with a catch 14, catch 14 is perpendicular with axle center 12, protractor 10 and metal finger 11 are enclosed within the both sides of axle center upper stop piece 14 respectively, be tightened on chute 5 with positive and negative screw 13,13 ' respectively, angle measurer 2 can according to patient's actual lesion position different and in chute 5 stepless being free to slide.Base 3 is an arc hard plastic board, its arc degree is consistent with the CT bed, be respectively with a strip magic glue 15 on base 3 dual-sides, by with bottom, U template 4 both sides square plate 6 on magic glue 7 bondingly fix U template 4, U template 4 can move up and down according to patient's actual lesion position is different; Base 3 central authorities are provided with four " one " font holes 16 again, are installed with in the hole in order to fixing patient's fixing band 17.
