CT real-time guide puncture positioning device

Abstract

The invention provides a CT real-time guide puncture positioning device. A lifting sliding rail capable of longitudinally sliding is installed on a sliding rail base capable of being fixed to a CT bed plate; a transverse sliding rail capable of being adjusted in a lifted manner is installed on the lifting sliding rail; a three-dimensional holder capable of transversely sliding is installed on the transverse sliding rail; and a puncture module is arranged at the outer end of a universal adjusting rack. A double-shaft digital readout angle gauge is arranged on the puncture module. When the CT real-time guide puncture positioning device is used, sliding adjustment can be achieved through cooperation of the whole; the puncture module is in calibration alignment with a puncture part of a patient during scanning; the angle of the puncture module is well adjusted; and a puncture needle head directly punctures a focus part of the patient through a corresponding needle hole in the puncture module. The CT real-time guide puncture positioning device can synchronously move along with the CT bed plate; a puncture needle can be fixed during CT scanning verification; and monitoring can be repeatedly verified in real time. By means of the CT real-time guide puncture positioning device, the puncture accuracy is greatly improved; and the one-time success rate can be improved to more than 95%.

Description

Technical field [0001] The invention relates to an instrument used when a hospital adopts CT scanning puncture for a patient, in particular to a puncture positioning device guided by CT in real time. Background technique [0002] When hospitals use CT scans to perform puncture and extract pathological samples for patients, they need to locate the lesion site and perform puncture through the scan. The traditional method is that in the case of CT scans, the doctor grasps the direction of needle insertion by hand based on medical skills and experience. It is implemented artificially, and the difference in medical skills and experience makes it difficult to accurately puncture to the correct site at a time, resulting in repeated needle adjustments and repeated CT scan verification. This inaccurate puncture directly increases The patient’s pain is reduced, and the operation time is long. At the same time, there are many problems such as the need for medical staff to hold the needle fo...
