Problems solved by technology
Although measures have been taken to find the best puncture path before the puncture is performed, it may still deviate slightly from the puncture path due to slight movement of the patient or operator error, and the puncture needle may damage the blood vessel after entering the human body. Even destroy the large blood vessels called the aorta
[0004] The ablation needle / puncture needle destroys blood vessels and even destroys aortic vessels, which is very dangerous to the human body

The invention provides puncture equipment. The puncture equipment comprises a puncture needle, a heating element, a temperature measuring element and a controller, wherein the heating element is arranged in a needle point of the puncture needle; the temperature measuring element is arranged in the puncture needle and is used for measuring the temperature of the needle point of the puncture needle; and the controller is used for controlling a driving circuit to apply adjustable current to the heating element after the puncture needle pierces into a target object by a first depth so as to allow the temperature of the needle point of the puncture needle to be maintained at a target constant temperature, monitoring the adjustable current applied to the heating element by the driving circuit in the process that the puncture needle continues to pierce the target object and determining a distance value between the needle point of the puncture needle and a blood vessel according to a preset current relationship between the adjustable current and the distance.
Description
technical field [0001] The present application relates to the field of intelligent medical technology, in particular to a puncture device. Background technique [0002] In tumor ablation therapy, it refers to the local interventional therapy technology that directly destroys the tumor by various physical methods. When performing tumor ablation therapy, it is first necessary to determine the location of the lesion in the patient's body, then determine the puncture path, and finally the doctor performs the operation: insert the ablation needle / puncture needle into the human body according to the puncture path, and then control the ablation device to perform corresponding actions . [0003] In the related art, the puncture path and the location of the lesion are displayed through a three-dimensional model, which provides guidance for the doctor's operation to a certain extent. Based on surgical navigation technology, the ablation needle / puncture needle can be automatically al...
