Description
Technical Field
The utility model relates to an accurate positioning and repeated positioning fixing technology in the tumor radiotherapy process, in particular to a radiotherapy prone position fixing device for protecting the small intestine of a patient with abdominal pelvic tumor in the radiotherapy process.
Background
With the wide application of the precise radiotherapy technology, higher requirements are put forward on the repeatability of the body position fixing device and the daily positioning of the patient. The size of the positioning error is directly related to the control rate of the tumor and the incidence rate of complications of normal organs. The irradiated volume and dose of the small intestine are closely related to the adverse reaction caused by radiotherapy of the patient with the abdominal pelvic tumor. The small intestine is the moving organ and a single static CT image presents uncertainty in the assessment of protection of the small intestine. The traditional common supine position fixing mode is difficult to well protect small intestines, and the existing abdomen prone position fixing device is not provided with a vacuum negative pressure system, so that the individualized setting of a patient cannot be realized, the good repeatability of the position of the small intestines of the patient cannot be guaranteed, the sagging degree of the small intestines of the patient treated at every time is different, even the sagging degree is not enough, and the treatment effect is greatly influenced. Therefore, the manufacturing of a negative pressure vacuum fixing system for prone position of abdominal-pelvic radiotherapy, which enables the abdomen of a patient to naturally droop and has good repeatability, is a problem to be solved urgently by those skilled in the art.
The utility model has the following contents:
in order to overcome the not enough of the flagging degree of small intestine among the current radiotherapy fixing device technique, the different defect of flagging degree of radiotherapy pendulum position at every turn, the utility model provides a can be to the abdominal basin portion radiotherapy prone position vacuum fixing system of different patient's size. The system adopts silica gel materials to make covers with three specifications of different sizes, a patient lies on the silica gel covers, and simultaneously air is pumped by a small air pump to assist the abdomen to droop, so that the evacuated silica gel covers form a fixed shape according with the body type of the patient.
The negative pressure body position fixing system for protecting the small intestine of a patient with abdominal pelvic tumor in the radiotherapy process comprises a prone body frame (1), a silica gel vacuum cover (2) and a small air pump (3).
The prone position frame comprises a carbon fiber bottom plate (4), a body pad (5), a chest pad (6) and an abdomen framework (7). The carbon fiber bottom plate is made of carbon fiber composite materials and is used for achieving an integrated rigid supporting effect on the whole device. The left side and the right side of the carbon fiber bottom plate are respectively provided with an outer frame of 5cm and used for fixing a thermoplastic film for radiotherapy positioning. The fiber carbon soleplate has two adjustable positions at the body pad and the chest pad. The body pad and the chest pad are fixed on the carbon fiber bottom plate through strip-shaped buckle pieces (12). The body pad has three wave-shaped depressions which conform to the contour of the human body. The chest pad has uniform thickness, flexible material and better comfort. The abdomen framework is fixed on the carbon fiber base plate through screws, and the middle opening part is used for placing the silica gel cover.
The silica gel vacuum cover is manufactured into A, B, C three different models according to different body types of patients. A is a thin and small silica gel cover, B is a medium silica gel cover, and C is a large silica gel cover. The silica gel vacuum cover is filled with composite silica gel particles and is tiled on the opening of the abdomen frame. The silicone cover accommodates a maximum abdominal droop of 20cm apart. The patient lies prostrate on prone position negative pressure vacuum fixing system, adjusts the position of body pad, belly frame and chest pad, and the belly aligns the silica gel cover entrance to a cave, and in the small intestine droops to the entrance to a cave, through the air in the small-size aspiration pump extraction silica gel cover, the production accords with the individualized shape of patient's abdomen pelvic part.
Each gear on the carbon fiber bottom plate is fixed through a nut structure, different gears of the carbon fiber bottom plate are combined with the chest module and the body module, and personalized setting can be achieved for patients with different body types, so that the best comfort is achieved. The silica gel cover is connected with a small-sized air pump through a connector pipe, a locking device is arranged at the connector, and an air pumping port is locked after air pumping is finished, so that air leakage is prevented, and the shape of the vacuum pad is kept unchanged.
The beneficial effects of the utility model are that, this abdomen basin radiotherapy prone position negative pressure vacuum fixing system prone frame middle part is opened the hole, and the small intestine region is flagging naturally, keeps away from the radioactive ray irradiation region. The chest supporting block and the abdomen supporting block can move positions, thereby being suitable for patients with different heights. The special three prone position silica gel vacuum covers with different sizes are suitable for patients with different fat and thin, so that the comfort of the patients and the repeatability of treatment each time are improved. The negative pressure vacuum fixing system for the ventral pelvic radiotherapy prone position is reasonable in design and humanized, small intestines of patients undergoing the ventral pelvic radiotherapy can be prevented from being irradiated by high dose and large area, the irradiated dose of the small intestines is reduced, and the risk of perforation and necrosis of the intestines of the patients is reduced.
