Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a puncture surgical instrument device. Background Art
[0002] In the field of cancer pain treatment, conservative treatment has always followed the "three-step" medication principle of analgesics to relieve cancer pain; for refractory cancer pain, the fourth-step minimally invasive surgery method is used, including nerve damage, morphine pump implantation and spinal cord stimulation. From a mechanistic point of view, the only way to relieve refractory cancer pain is to relieve the compression of the tumor on the nerves, eliminate abnormal nerves and reduce the volume of the tumor in order to truly achieve causal treatment. In order to relieve refractory cancer pain, countless excellent doctors have always used minimally invasive analgesia for cancer pain. The technology uses nerve or drug intervention away from the tumor site, and has never intervened in the tumor itself or surrounding tissues. There has never been a substantial breakthrough in solving refractory cancer pain.
[0003] The main difficulty is that the boundary between malignant solid tumors and nerves in the body is unclear, and it is impossible to accurately identify the tumor, the affected pain point nerves, and the abnormally growing nerves in real time and effectively; invasive operations such as loosening the tumor itself or surrounding tissues have the risk of promoting tumor metastasis; there is a lack of equipment that can effectively ablate the tumor and protect the nerves. Clinically, there is an urgent need for a minimally invasive analgesic surgical device that can not only identify the tumor pain point in real time and safely and effectively ablate the pain point, but also loosen the nerves and ablate the tumor tissue to reduce metastasis.
