Auxiliary device for chest positioning puncture under CT guidance

Technical Field

The utility model belongs to the technical field of the medical science, concretely relates to chest location puncture's auxiliary device under CT guide.

Background

The breast tumor is the first place at present in the tumor incidence part, and especially the lung cancer becomes the disease with higher incidence of malignant tumor in China. The CT percutaneous thoracic puncture biopsy has wide application, and the biopsy diagnosis sensitivity, specificity and accuracy of the thoracic puncture are limited to different degrees due to the defects of the generating part of the tumor, the surrounding tissues and viscera and the guiding equipment of the CT percutaneous thoracic puncture biopsy due to different puncture needles or guns and positioning methods, and complications cannot be avoided. In the appearance of CT, the relationship between the focus and the surrounding visceral organs and the large blood vessels is clearly displayed by reconstructing an intuitive three-dimensional image and rotating in multiple directions, so that the relationship between the focus and the surrounding visceral organs and the large blood vessels is intuitively known, the needle insertion direction is guided, and important visceral organs and the large blood vessels are avoided. How to find the optimal positioning point before puncture is the most important step for judging whether the puncture is successful and smooth, and the optimal puncture scheme is provided for an interventionalist.

The existing chest positioning puncture process comprises the steps of firstly scanning for the first time, judging a focus part and a probable puncture point, placing a marker in a intercostal space through image reference direction and body surface measurement, then scanning for the second time, placing the marker again if the placement is not accurate, scanning again to determine the puncture point, and repeating the steps so as to find the optimal puncture point. Due to the irregular rib deformation, errors and repeated scanning are easily caused in the process, the radiation dose of a patient is increased, the puncture operation time is prolonged, and the problems of scientificity and rigor are lacked, so that an auxiliary device for chest positioning puncture under CT guidance is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an auxiliary device of chest location puncture under CT guide to it carries out the first scanning earlier to propose current chest location puncture process in solving above-mentioned background art, judges focus position and probably puncture point, measures through image reference position and body surface and places the marker in the intercostal clearance, scans for the second time again, if place the unsafe then puts the marker again, scans once more and confirms puncture point, so relapse so that find best puncture point. Due to the irregular shape of the rib, the process is easy to cause errors and repeated scanning, and the problems of increasing the radiation dose of the patient and the time of the puncture operation are solved.

In order to achieve the above object, the utility model provides a following technical scheme: CT guides auxiliary device of chest location puncture down, including horizontal strip and vertical strip, a side end integral type of horizontal strip all is connected with the second fixed block, the front surface of second fixed block all is provided with Arabic number reference numeral, just the terminal equal fixedly connected with elastic band in both sides of horizontal strip, the top homogeneous style of vertical strip is connected with first fixed block, the front surface of first fixed block all is connected with Roman number reference numeral, just the net has been seted up between horizontal strip and the vertical strip.

Preferably, the transverse strips, the longitudinal strips, the first fixing block and the second fixing block are subjected to low-temperature sterilization treatment.

Preferably, the two elastic bands are tightly connected with the transverse strips and the longitudinal strips.

Preferably, the grid is a group of rectangles with equal adjacent sides, and the side length of the grid is 3 cm.

Preferably, the diameter of the transverse and longitudinal bars is equal to 2.5 mm.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses just can show the scope of focus and the accurate demonstration of body surface sign when scanning for the first time under the CT guide, need not to scan repeatedly can be quick accurate find best point of puncture, and can guarantee the accuracy nature of puncture, reduce patient's the radiation dose of being irradiated and puncture time.
