Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0019] Example: refer to Figures 1 to 3 As shown, a human thoracic and abdominal cavity three-dimensional breathing motion simulation device includes a base plate 1, a support rod one 2, a support rod two 3 and a support rod three 4 vertically fixed on the base plate 1; one end is vertically fixed on the middle part of the support rod three 4 Connecting frame rod one 5, one end is vertically fixed on the connecting frame rod two 6 of support rod three 4 tops; Rotating disc one 7 and rotating disc two 8 that are connected with the tops of support rod one 2 and support rod two 3 in rotation respectively, The rotating disc three 9 that is rotatably connected with the other end of the link rod one 5 is respectively arranged on the arc groove one 10 and the arc groove on the rotating disc one 7, the rotating disc two 8 and the rotating disc three 9. Two 11 and a...

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 auxiliary simulation devices for medical equipment, and in particular relates to a three-dimensional breathing motion simulation device for the chest and abdomen of a human body. Background technique [0002] With the aggravation of environmental pollution and life pressure, cancer has become one of the main problems plaguing human health. For cancer, surgical treatment, chemotherapy and radiotherapy are the three major methods. Among them, radiotherapy has developed rapidly because it can treat tumors in special locations and has low requirements on the patient's physical condition, resulting in image-guided stereotactic radiotherapy equipment such as Cyberknife. Due to the strong lethality of radiation, precise positioning of tumor lesions is required, and the respiratory movement of the patient is the main factor that interferes with the precise positioning of tumors. And it has a nonlinear and time-lag relatio...
