A robot device that uses CT perspective to guide remote real-time puncture

Abstract

The invention discloses a robot device for guiding remote-control real-time puncture by means of CT fluoroscopy. The robot device for guiding remote-control real-time puncture by means of the CT fluoroscopy comprises a lower stand column (100), an upper stand column (200) and a connecting frame (300). The bottom end of the upper stand column (200) is connected with the top end of the lower stand column (100), and the upper stand column (200) can slide relative to the lower stand column (100); one end of the connecting frame (300) is arranged on the upper stand column (200) in a sleeving mode, and a sleeve (301) is fixedly arranged at the other end of the connecting frame (300); a cross beam (302) penetrates through the interior of the sleeve (301), and the cross beam (302) can move freely in the direction of the sleeve (301); a cross beam tip (303) is fixedly arranged at one end of the cross beam (302); a round rotary disc (304) is arranged on the cross beam tip (303), and the round rotary disc (304) can rotate freely around the center axis of the cross beam (302) relative to the cross beam tip (303); a sliding groove (305) is formed in the surface of the round rotary disc (304), a sliding block (306) is arranged in the sliding groove (305), and the sliding block (306) can slide freely in the sliding groove (305). When the robot device is used by a doctor for remote-control real-time puncture, radiation of rays to the doctor can be avoided, and the doctor can operate a puncture needle more conveniently.

Description

technical field [0001] The invention relates to the technical field of using CT perspective to guide remote control real-time puncture. More specifically, it relates to a robot device that uses CT perspective to guide remote real-time puncture. Background technique [0002] In the prior art, no matter what kind of navigation technology is used, the CT-guided puncture method is to perform a CT scan on the diseased body part first, and obtain a CT image after the scan is completed. The puncture needle is blindly pierced to the lesion location in the patient's body. The disadvantage of this method is that the doctor cannot accurately judge whether the needle tip of the puncture needle has reached the lesion in the patient's body, and cannot see the abnormal changes caused by the puncture needle moving in the patient's body, so the accuracy and safety are not guaranteed. If the doctor wants to accurately judge the actual position of the needle tip and the changes in the body c...

Problems solved by technology

The disadvantage of virtual navigation is that it cannot immediately reflect the patient's tissue space structure to the doctor, and there is a certain time delay between the two

The biggest disadvantage of assisted puncture with various navigation devices is that it cannot overcome the influence of the patient's physiological movement such as breathing on the angle and position of the puncture needle during the puncture process, and the doctor cannot observe the movement direction of the puncture needle in the patient's body and the actual position of the needle tip in real time. Therefore, the impact of puncture on the patient's tissues and organs cannot be avoided, such as bleeding and pneumothorax caused by puncture, and fatal damage to vital organs caused by puncture

[0006] In the prior art, there is no robot device that uses CT perspective to guide remote control real-time puncture
