Intelligent laser-guided positioning sampling device for CT (computed tomography) puncture

Abstract

The invention relates to the technical field of devices for puncture sampling, in particular to an intelligent laser-guided positioning and sampling device for CT puncture. The device comprises a device body, a puncture mechanism and a control mechanism, the puncture mechanism comprises a mechanical arm, and the mechanical arm is located on the top end surface of the device body; the tip rotating block is located on the end face of one end of the mechanical arm; the sliding rail is arranged on the outer side of the tip rotating block; the sliding blocks are connected to the inner sides of the sliding rails in a sliding manner; one end of the puncture needle is movably connected to the inner side of the sliding block, and the other end of the puncture needle is located on the outer side of the sliding block. The control mechanism comprises an intelligent laser guiding system module, an execution control module, a detail adjustment module, a data recording module and a data display module, and the intelligent laser guiding system module, the execution control module, the detail adjustment module, the data recording module and the data display module are all located in the device body; when puncture sampling is needed, the device main body and the mechanical arm are combined with each other, and automatic puncture sampling is achieved.

Description

technical field [0001] The invention relates to the technical field of puncture sampling devices, in particular to a CT puncture intelligent laser-guided positioning sampling device. Background technique [0002] At present, the CT machines on the market only have three laser positioning lights at 12 o'clock and 3 o'clock and 9 o'clock, which are used for the positioning of daily CT scans. However, CT-guided puncture of these three lights can provide limited help. At present, puncture doctors want to find the puncture point by measuring the patient's body surface with a ruler at the puncture level. The puncture angle is determined manually by the doctor's technique and experience. This will undoubtedly increase the number of needles or increase the risk. The intelligent laser guidance and positioning system can design the path and angle at the level that the doctor wants. The intelligent laser positioning sampling device will point out a red laser puncture point on the pa...

Problems solved by technology

[0003] For example, a remote intelligent calibration laser positioning system based on X-ray image guidance disclosed in the invention with the authorized announcement number CN110180093A, although it can allow the system to judge the puncture point and puncture angle, it is not combined with CT puncture and cannot be controlled by the system. While judging the puncture location and angle, the system performs puncture sampling. For this reason, we propose a CT puncture intelligent laser-guided positioning sampling device.
