Instrument intervention device and system

Abstract

The embodiment of the invention provides an instrument intervention device and system, and belongs to the technical field of medical instruments. The instrument intervention device comprises an imagepoint cloud module, a real-time point cloud module, a point cloud registration module, a real-time error module, an intervention safety line module and an output module; and through mutual connectionand cooperation of the modules, the real-time error and an intervention safety line of registration of an image point cloud and a real-time point cloud are calculated, and when the real-time error islower than the intervention safety line, an intervention signal is output outwards, so that a medical worker performs the intervention process of instruments. The opportunity of instrument intervention can be determined on the basis of the position relation between the body surface of a human body at a certain moment and a target area, and the dependence on artificial experience during intervention opportunity judgment is avoided.

Description

technical field [0001] The embodiments of the present application relate to the technical field of medical devices, and in particular, to a device and system for interventional devices. Background technique [0002] In the intervention process of the existing minimally invasive treatment, which path and when the intervention instrument is to intervene are the keys to complete the entire intervention process. [0003] The current interventional path mostly uses preoperative medical images, and the interventional path is planned according to the preoperative medical images, so as to achieve the purpose of avoiding the main blood vessels and certain organs during the interventional process, so that the interventional instruments can accurately reach the target area. [0004] However, since the breathing of the human body does not stop during the intervention process, the positions of blood vessels and various organs in the human body will change at any time during the breathing...

Problems solved by technology

[0004] However, since the breathing of the human body does not stop during the intervention process, the positions of blood vessels and various organs in the human body will change at any time during the breathing process, resulting in the intervention process of the device is very dependent on the doctor's personal experience, and may even require multiple doctors They cooperate with each other and need to use ultrasound images to obtain the actual positions of blood vessels and various organs in real time. However, on the one hand, ultrasound imaging is a fan-shaped image, and the imaging quality is not ideal. The understanding of ultrasound images and the imagination of physiological structures basically depend on the experience of doctors. On the other hand, ultrasound images are two-dimensional images, which can only reflect various physiological structures in one plane, and cannot reflect the relative positions of human blood vessels and various organs as a whole.

[0005] In summary, the use of existing interventional techniques cannot accurately plan the intervention path and intervention timing
