Description

CT real-time guided puncture positioning device

technical field

The utility model relates to an instrument used in a hospital to scan and puncture a patient by CT, in particular to a puncture positioning device under the real-time guidance of CT. the

Background technique

When the hospital uses CT scans for puncture to extract pathological samples for patients, it is necessary to locate the lesion through the scan and perform puncture. The traditional method is that in the case of CT scans, doctors use their hands to grasp the direction of needle insertion based on medical skills and experience. It is carried out artificially, coupled with the difference in medical skills and experience, it is difficult to accurately puncture to the correct position at one time, resulting in the phenomenon of repeated adjustment of the needle and repeated CT scan verification. This kind of puncture that cannot be accurately in place will directly increase It reduces the pain of the patient, and causes a long operation time. At the same time, there are many problems such as the need for medical staff to hold the needle for CT scan verification, and poor repeatability. the

Contents of the invention

The purpose of the utility model is to solve the above-mentioned problems, and to provide a puncture positioning device guided by CT in real time, which has the characteristics of convenient operation and accurate puncture. the

The utility model includes the three-dimensional platform of the device, and the adopted technical scheme is that: the slide rail seat that can be fixed on the CT bed board is equipped with a vertically slidable lifting slide rail, and the lifting slide rail is equipped with a vertically adjustable horizontal The slide rail is equipped with a three-dimensional pan-tilt which can slide laterally on the transverse slide rail, and a puncture module is arranged at the outer end of the three-dimensional pan-tilt. There is a dual-axis digital goniometer on the puncture module. the

In the above technical solution: the slide rail seat is connected and fixed with the CT bed board through a fixing clip. the

The lifting slide rail is installed on the slide rail seat through the slider seat at the bottom. the

The end of the three-dimensional pan/tilt is connected with a slider and a horizontal slide rail to form a sliding structure that can be adjusted horizontally by the universal adjustment frame. the

Through the above technical scheme, the utility model adopts an overall structure that can slide up and down and laterally, and can adjust various angles, and a puncture module is set in the overall structure. When used after installation, the overall device can be used in CT Under the premise of scanning, adjust the corresponding pinhole on the puncture module to the lesion of the patient through the adjustment of up and down, left and right, and the angle. After adjusting the puncture angle, the corresponding pinhole on the puncture module can be directly inserted into the needle for puncture. This can achieve the effect of greatly improving the accuracy and success rate. The overall structure can move synchronously with the CT bed, can quickly adjust various precise angles, and can conveniently display the horizontal status of various angles, and the fixed puncture needle can realize real-time monitoring during CT verification. After making sample experiments, the average error of puncture was reduced from 34mm to 4mm. After trial on 20 patients, the one-time success rate increased from 40% to 95%, and the operation time was shortened from 30 minutes to less than 10 minutes. At the same time, Due to the short operation time, the number of CT scans has also been reduced from an average of 6.5 to 2.05, reducing the radiation dose of patients from 65mSv to 15mSv, and correspondingly reducing the radiation dose of surgical personnel from 20mSv to 3mSv . The utility model effectively solves many problems existing when hospitals use CT to perform puncture operations for patients, and has the remarkable characteristics of improving accuracy and success rate. the

Detailed ways

As shown in Figure 1: the slide rail seat 1 that can be fixed on the CT bed board 9 is equipped with a vertically sliding lifting slide rail 4, and the lifting slide rail 4 is equipped with a horizontal slide rail 5 that can be lifted and adjusted. A three-dimensional pan-tilt 7 that can slide laterally is installed on the top, and a puncture module 8 is arranged at the outer end of the three-dimensional pan-tilt 7 . The slide rail seat 1 is connected and fixed with the CT bed board 9 through the fixing clip 2 . The lifting slide rail 4 is installed on the slide rail seat 1 by the slider seat 3 at the bottom. The tail end of the three-dimensional pan-tilt 7 is connected with the lateral slide rail 5 by a slider 6 to form a laterally adjustable sliding structure of the three-dimensional pan-tilt 7 . the

The puncture module 8 can be made of hard plastic, and a plurality of pinholes with different apertures are distributed on the block during manufacture. The puncture module 8 should have a certain thickness so that the needle can be better positioned. During use, a device for calibrating the horizontal state and the angle of the puncture needle can be placed on the puncture module 8 to better meet the surgical requirements. Simultaneously, the whole body can be fixed on the side or tail of the CT bed plate 9 through the slide rail seat 1, which can be determined according to actual needs. In the use state, the device can move synchronously with the CT bed board, so that the puncture needle can be fixed during CT verification, and the operation is more convenient. the
