Problems solved by technology

The position change of the puncture center and human error caused by the patient's spontaneous breathing or heartbeat will directly affect the accuracy of the puncture position.
And due to the limitations of the current technology, the puncture path defined by the operator is basically vertical, which makes it impossible for the puncture needle to avoid sensitive organs or tissues in some cases, which brings great harm to the puncture. inconvenience and danger

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] refer to Figure 2-6 , the positioning device fixed on the puncture needle and the positioning device on the body surface of the human body are infrared positioning balls that can be identified by the high-precision infrared monitoring equipment. The surface of the infrared positioning ball is covered with a layer of material that can reflect most of the incident infrared light. The infrared light emitted by the high-precision infrared monitoring equipment is reflected back by the small ball, and the monitoring equipment receives the reflected infrared light, analyzes the data and calculates the three-dimensional position coordinates of the small ball, and realizes the purpose of the monitoring and positioning device.

Abstract

The invention discloses a computer-assisted puncture navigation system and a computer-assisted puncture navigation method under infrared guidance. The computer-assisted puncture navigation system and the computer-assisted puncture navigation method have the advantages that problems of human movement due to respiration, heartbeat, unconscious movement and the like of people, deviation such as angular deviation between existing puncture needles and existing puncture paths and distance deviation between needle points of the existing puncture needles and existing puncture centers and severe influence on existing puncture procedures can be solved by the aid of the computer-assisted puncture navigation system and the computer-assisted puncture navigation method; the infrared positioning method is implemented by the aid of the computer-assisted puncture navigation system, locations of puncture needles are monitored in real time in puncture procedures, and accordingly operators can timely find and correct deviation.

Description

technical field [0001] The invention discloses a computer-aided puncture navigation system and method under infrared guidance. The system can locate the puncture needle and the puncture center in real time during the puncture process, and monitor the process in the computer, so that the puncture needle and the predefined puncture can be obtained immediately. deviation between paths. Background technique [0002] Needle aspiration is a relatively common technique in modern surgery. The operator uses the puncture needle to puncture the tissue or organ of the human body to complete operations such as biopsy and local anesthesia. This technology is widely used in the diagnosis and treatment of human lungs, kidneys, spine and other organs and tissues. [0003] In puncture surgery, puncture accuracy is the key to the success of the operation, but currently the accuracy of puncture mainly depends on the operator's experience and technique. The operator can only determine the pun...
