Problems solved by technology

Clinically, in order to avoid the influence caused by respiratory movement, patients are generally asked to scan CT or MRI under breath-holding, and after determining the tumor location, the puncture is also performed under breath-holding, but there are cases where patients' breath-holding is inconsistent; in addition, some patients are limited by their physical conditions , unable to cooperate with the doctor to perform breath-holding operation, need to perform puncture under natural breathing
[0003] At present, the percutaneous puncture t...

Abstract

The invention is applicable to the technical field of operation training devices, and provides a tumor respiratory movement simulation platform and a tumor position estimation method, the tumor respiratory movement simulation platform is used for percutaneous puncture operation, and comprises a human abdomen phantom which is of an inner hollow structure and is covered with humanoid skin, and positioning mark points are arranged on the humanoid skin; the air bag is fixedly arranged in the human abdomen phantom and can be circularly inflated and deflated, and the air bag is always kept in contact with the humanoid skin in the inflating and deflating process; the guide rail is arranged on the human abdomen body membrane and is opposite to the humanoid skin; the displacement plate is connectedto the guide rail in a sliding mode, one side of the air bag abuts against the displacement plate, and the displacement plate reciprocates on the guide rail along with inflation and deflation of theair bag; and the puncture simulation body is fixedly arranged on the displacement plate, and a puncture target point is arranged in the puncture simulation body. According to the invention, a puncturescene closer to clinic is provided for doctors.

Description

technical field [0001] The invention relates to the technical field of surgical training devices, in particular to a tumor respiratory motion simulation platform and a tumor position estimation method. Background technique [0002] Percutaneous puncture surgery is a kind of surgery that directly punctures into the tumor through the human skin to obtain biological tissue samples or treat tumors. It is widely used in the fields of cancer biopsy diagnosis and ablation therapy, and is an important means of tumor diagnosis and treatment. The positions of human thoracoabdominal organs are significantly affected by respiratory movement. For example, the displacement of the liver in the direction of the head and feet is as high as 22mm, which will seriously affect the precise puncture of the tumor. Clinically, in order to avoid the influence of respiratory movement, patients are generally asked to scan CT or MRI under breath-holding, and then perform puncture while holding the patie...
