Embodiment Construction

[0013] An intelligent positioning system for puncture under the guidance of CT, which is composed of a working system integrating puncture path software, a main controller and an executing mechanism. The system is composed of an image collector and an image processor connected in sequence; the main controller actuator is composed of a support 1, an X-axis actuator 2, a Z-axis actuator 3 and a guiding puncture device. The X-axis actuator can be left or right. The moving slideway 4 is installed above the support. The Z-axis actuator is an actuator arm 5 that can move up and down. It is vertically installed on the X-axis actuator. The bottom of the Z-axis actuator is equipped with a 360° rotating Guided puncture device; the X-axis actuator, the Z-axis actuator and the guide puncture device are respectively equipped with a stepper motor that can control the X-axis actuator to move left and right 6, and a stepper motor that can control the Z-axis actuator to move up and down 7. The...

Abstract

A puncturatio intelligent positioning system under the guidance of CT consists of a working system with the puncturatio path software concentrated on the inner part, a main controller and an actuator, wherein, the working system is connected with the main controller bidirectionally, the working system is formed by connecting the image collector and the image processor sequentially, the actuator consists of a supporting frame, an X-shaft actuator, a Z-shaft actuator and a guide puncturatio device. The invention has the advantages that: 1. the accuracy of puncturatio operation is largely improved, the possibility of the puncturatio of dissecting the more complex part is provided, the suitable scope of the CT guiding the puncturatio is largely enlarged, therefore, the diagnosis and treatment of some disease are largely simplified, the pain of the patient is reduced, the medical cost is reduced at the same time; 2. the invention has simple structure and convenient operation.

Description

Technical field: [0001] The invention relates to medical inspection equipment, in particular to a CT-guided puncture intelligent positioning system. Background technique: [0002] With the continuous advancement of CT examination technology, CT-guided puncture technology is becoming more and more mature. Most of the current CT-guided puncture operations are done manually. The medical personnel select the puncture point on the human body according to the needle insertion point and needle insertion angle determined on the CT scan, mainly relying on the experience and technical level of the operator. Puncture, so the accuracy of puncture is relatively poor, and sometimes even repeated puncture occurs, prolonging the operation time, bringing pain to the patient, and greatly reducing the scope of application of puncture. [0003] At present, there are two types of navigation systems for precise positioning of punctures in the world. One is passive, which uses images to guide the...
