Demonstration and education system for male pelvic tumor patients

Abstract

The invention relates to a demonstration and education system for male pelvic tumor patients. The demonstration and education system includes a supporting part, a bladder part which is arranged on the supporting part and represents the bladder, a rectum part which is arranged on the supporting part and represents the rectum, a pubis part which is arranged on the supporting part and represents thepubis, the prostate part represents the prostate, and the prostate part is arranged among the bladder part, the rectum part and the pubis part; the bladder part and the rectum part are respectively of a hollow structure and have elasticity, and the bladder part and / or the rectum part are / is used for expanding and extruding the prostate part under the action of internal pressure, so that the prostate part deforms and / or shifts; the demonstration education system is compact in structure and reasonable in design, influence of the filling degree of the bladder and the rectum on the position of the target area on the prostate can be visually reflected, quantitative measurement can be achieved, demonstration of a patient needing prostate radiotherapy is facilitated, the patient is urged to manage the bladder and the rectum of the patient, and the prostate radiotherapy instrument can be used for teaching and research.

Description

technical field [0001] The invention relates to the technical field of tumor radiotherapy, in particular to a demonstration education system for male pelvic tumor patients. Background technique [0002] With the advancement of science and the continuous development of technology, precision radiotherapy has attracted more and more attention in the field of tumor radiotherapy, and has already become an important development direction of tumor radiotherapy. [0003] During radiation therapy, millimeter-level movements may cause serious side effects and sequelae, and because radiation therapy is a delayed effect, that is, there is no feeling at the moment of occurrence, it becomes very difficult to control; for patients with pelvic tumors Especially for male pelvic tumor patients, the proportion of prostate tumor patients is relatively high. The anatomical location of the prostate is the bladder in the front and the rectum in the back (that is, the prostate in the pelvis is just...

AI Technical Summary

Problems solved by technology

[0003] During radiation therapy, millimeter-level movements may cause serious side effects and sequelae, and because radiation therapy is a delayed effect, that is, there is no feeling at the moment of occurrence, it becomes very difficult to control; for patients with pelvic tumors Especially for male pelvic tumor patients, the proportion of prostate tumor patients is relatively high. The anatomical location of the prostate is the bladder in the front and the rectum in the back (that is, the prostate in the pelvis is just sandwiched between the bladder and rectum), and the bladder and rectum Due to the structure of the physiological lumen, both liquid and gas will cause large changes in the two lumens, especially the volume change, which will squeeze the nearby organs (such as the prostate) and cause the nearby organs to shift. If the tumor requiring radiation therapy is located on this organ, it will lead to the displacement of the tumor target area, and according to the research results published in the prior art, it is known that changes in the bladder and / or rectum can even affect the tumor target area. The position produces a huge error of more than 50mm

[0004] In tumor radiation therapy, the irradiation path of radiation is usually prepared in advance and corresponds to the position of the target area. When the position of the target area changes or shifts, the radiation cannot be irradiated accurately on the target area and achieve the therapeutic effect. effect, and it will irradiate on normal organs, destroying the normal organs of the human body; therefore, in the prior art, before performing radiation therapy, medical staff usually need to educate prostate tumor patients undergoing radiation therapy, so that patients can Better management of the bladder and rectum, so that the position of the target area will be kept as consistent as possible during each radiotherapy, so as to achieve precise radiotherapy. However, in the prior art, the teaching methods for patients are very weak, and patients usually cannot understand and understanding, thereby detrimental to patient management of bladder and rectum, very detrimental to achieving precise radiotherapy
