Problems solved by technology

Because the required puncture force is very large, if the control is not good, the ablation needle will easily deviate
After the puncture into the human body, a ruler is needed to measure whether the insertion depth of the ablation needle conforms to the surgical plan. Once the depth is not enough, the puncture needs to be continued, causing the patient to suffer the pain of puncture again; if the insertion is too deep, it is easy to damage other organs and tissues

Abstract

The invention provides a handheld puncture device and a control method, the handheld puncture device is used for assisting puncture of a medical needle, and the handheld puncture device comprises a base body which is provided with a handle and a user input device used for receiving preset needle inserting information; a motor with a mover; a transmission mechanism is connected with the motor, and the transmission mechanism comprises a moving part used for connecting and fixing the medical needle; and a controller is used for controlling the operation of the motor according to the preset needle inserting information. According to the embodiment of the invention, the pain of a patient caused by misoperation of a doctor performing medical needle puncture can be reduced.

Description

technical field [0001] The present application relates to the technical field of medical equipment, in particular to a hand-held puncture device and a control method. Background technique [0002] Interventional cryoablation surgery requires the use of a cryoablation needle to ablate the tumor site. Doctors need to plan the angle and depth of the cryoablation needle into the human body before surgery to achieve better surgical results and needle access. In the past, the common practice was to determine the location and size of the tumor by taking CT tomographic scans or ultrasound images, and combined with the layout of human bones, blood vessels and nerves, to determine the passage of the ablation needle into the human body, that is, the inclination angle relative to the human body plane and the insertion depth. [0003] During the operation, the ablation needle is used to puncture into the human body. If the fascia or thoracic diaphragm is encountered during the puncture, ...
