A three-dimensional breathing motion simulation device for human thoracic and abdominal cavity

Abstract

The invention discloses a human body pleuroperitoneal cavity three dimensional breathing motion analogue device. A rotation disc 1, a rotation disc 2 and a rotation disc 3 drive a drift angle rod 1, a drift angle rod 2 and a drift angle rod 3 with same angular velocity through rotation; a connection rod 1, a connection rod 2 and a connection rod 3 drive a tumor simulation block to generate three-dimension movement; a guiding rod 1, a guiding rod 2 and a guiding rod 3 which are fixedly connected inside an arc groove 1, an arc groove 2 and an arc groove 3 are driven to rotate along with the corresponding rotation disc with the same angular velocity under the driving of the corresponding rotation disc; the guiding rod 1 and the guiding rod 2 pushes a chest wall simulation block to horizontally move along the X direction and the Y direction through corresponding groove rod and forked tail; and the guiding rod 3 enables the chest wall simulation block to vertically move along the Z direction through pushing the support plate. The human body pleuroperitoneal cavity three dimensional breathing motion analogue device can simulate the relevance three-dimension movement between the chest wall and the tumor during the breathing of the human body, provides original data to the accurate breathing tracking and can also be used as a test platform to verify the effectiveness of the breathing tracking scheme.

Description

Technical field [0001] The invention belongs to the field of medical equipment auxiliary simulation devices, and in particular relates to a three-dimensional respiratory motion simulation device of the human thoracic and abdominal cavity. Background technique [0002] With the increase of environmental pollution and life pressure, cancer has become one of the main problems that plague human health. For cancer, surgery, chemotherapy and radiotherapy are the three major methods. Radiotherapy has developed rapidly due to its ability to treat tumors in special locations and low requirements on the patient's physical condition, resulting in image-guided stereotactic radiotherapy equipment such as Cyberknife. Due to the powerful lethality of radiation, it is necessary to accurately locate the tumor focus, and the patient's breathing movement is the main factor that interferes with the precise positioning of the tumor. And it has a nonlinear and time lag relationship with the body surf...

AI Technical Summary

Problems solved by technology

This makes it difficult to ensure precise beam coverage of the targeted tumor during radiotherapy

Traditional control methods include respiratory gating, active breath-holding, etc., but strict requirements are placed on the patient's breathing and state, and the treatment accuracy is low
