Demonstration and education system for female pelvic tumor patients

Abstract

The invention relates to a demonstration and education system for female pelvic tumor patients. The system includes a supporting part, a bladder part which is arranged on the supporting part, a rectumpart arranged on the supporting part, a uterus part and a vagina part, and a cervix uteri part which is arranged between the uterus part and the vagina part. The uterus part, the cervix part and thevagina part are arranged between the bladder part and the rectum part; wherein 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 uterus part and / or the cervix part and / or the vagina part under the action of internal pressure and enabling the cervix part to deform and / or shift; The demonstration and education system is compact in structure and reasonable in design, influence of the bladder and rectum filling degree on the pelvic cavity tumor target area position can be visually reflected, quantitative measurement can be achieved, demonstration of a patient needing cervix uteri radiotherapy is facilitated so as to urge the patient to manage the bladder and rectum of the patient, and the device can be used for teaching and research.

Description

technical field [0001] The invention relates to the technical field of tumor radiation therapy, in particular to a demonstration education system for female pelvic tumor patients. Background technique [0002] The core essence of radiotherapy is to give a high enough dose (ray) to the tumor area and as low a dose as possible to the normal tissue area, so that the ideal state can achieve a very good therapeutic effect. [0003] In the course of 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; especially for For female pelvic tumor patients, such as cervical cancer patients, the anatomical location is the bladder in the front and the rectum in the back (for example, the cervix in the pelvis is just sandwiched between the bladder and rectum). , bladder urine filling, rectal gas, and fecal fi...

Problems solved by technology

[0003] In the course of 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; especially for For female pelvic tumor patients, such as cervical cancer patients, the anatomical location is the bladder in the front and the rectum in the back (for example, the cervix in the pelvis is just sandwiched between the bladder and rectum). , bladder urine filling, rectal gas, and fecal filling can all cause large changes in these two lumens, especially changes in volume, which can squeeze nearby organs (such as the cervix) and cause displacement of nearby organs, if The location of the tumor requiring radiation therapy on this organ will cause the position of the tumor target to be shifted, and according to the research results disclosed in the prior art, changes in the bladder and / or rectum can even affect the position of the tumor target. There is a huge error of more than 50mm, and the rectal wall is usually close to the cervix and uterine body, the effective distance cannot be opened by the dose distribution, and severe side effects of the rectum often occur

[0004] For patients with cervical cancer, the target area is located at the cervix. During radiation therapy, the irradiation path of radiation is usually prepared in advance and corresponds to the target area. When the position of the target area changes or shifts , radiation can not be accurately irradiated on the target area and achieve the therapeutic effect, but also can be irradiated on normal organs, destroying the normal organs of the human body; therefore, in the prior art, before performing radiotherapy, medical personnel usually need to Cervical cancer patients undergoing radiotherapy are educated so that patients can better manage their bladder and rectum so that the position of the target area will be as consistent as possible during each radiotherapy to achieve precise radiotherapy. However, in the prior art, The teaching methods for patients are very weak, and patients usually cannot understand and understand, which is not conducive to the effective management of bladder and rectum, or even ignores the management of bladder and rectum. In the current verification before radiotherapy, it is found that the bladder and rectum are often in a random state. The natural state is very unfavorable for precise radiotherapy
