Abstract

The utility model discloses a lower limb fixing device for radiation. The device comprises limiting rods and adapters movably connected to both sides of a treatment bed, one end of each limiting rod is detachably connected to the corresponding adapter, the inner side of the other end of each limiting rod is provided with a leg ring slidingly connected with the limiting rod, the leg rings are in parallel with the limiting rods and perpendicular to the treatment bed, and the limiting rods and the adapters are marked with scales. The defects of large setup error, poor repeatability and poor radiotherapy effect due to the fact that the legs cannot be fixed and the pelvic cavity position is easy to change during existing radiotherapy are overcome. According to the lower limb fixing device for radiation of the utility model, the legs can be positioned and prevented from position change and the pelvic cavity position change can be further avoided during radiotherapy, the positioning accuracy is improved, and the repeatability and the radiotherapy effect are good.

Description

Radiation lower limb fixing device

Technical field

This utility model belongs to for radiocurable apparatus field, is specifically related to a kind of radiation lower limb fixing device.

Background technology

In the therapeutic process of tumor, radiotherapy is absolutely necessary, conventionally need to be through radiotherapy knub position repeatedly, and repeatedly radiotherapy same position must guarantee same position, the accuracy of guarantee radiotherapy, accurate radiotherapy requires patient's pendulum bit error to be controlled at grade conventionally.During for tumor of pelvic cavity radiotherapy, at present, hospital mainly relies on patient's self restraint, controls shank, avoids shank to move as far as possible, adopts comfortable position, avoids patient tired mobile.Conventionally prostrate or dorsal position is more comfortable position, but, no matter patient adopts is lain on the back or ventricumbent position, both legs rely on the control force location of self, inconsistent when if both legs separate angle and CT simulation location, inconsistent can cause pelvic cavity position with simulation location time, thus it is large to make to put bit error; In Patients During Radiotherapy, the angle of both legs changes, is shifted, and all can make the deleterious of radiotherapy; In the process of repeatedly radiotherapy, be also difficult to guarantee that each position is consistent, poor repeatability, affects radiotherapeutic effect.

Utility model content

The technical problems to be solved in the utility model is during for existing radiotherapy, shank cannot be located, and pelvic cavity position easily changes, and causes putting bit error large, poor repeatability, the defect that radiotherapeutic effect is poor, positioning leg portions when a kind of radiotherapy is provided, avoids leg position to change, further avoid pelvic cavity position chanP, improve pendulum position accuracy, reproducible, the radiation lower limb fixing device that radiotherapeutic effect is good.

In order to solve the problems of the technologies described above, this utility model provides following technical scheme: radiation lower limb fixing device, comprise gag lever post and the adapter that is movably connected on therapeutic bed both sides, one end of gag lever post is removably connected on adapter, the other end inner side of gag lever post is provided with the lower limb ring being slidably connected with it, lower limb ring is parallel with gag lever post and vertical with therapeutic bed, and gag lever post and adapter are marked with scale.

Adopt the radiation lower limb fixing device of technical solutions of the utility model, comprise gag lever post, lower limb ring and be movably connected on the adapter of therapeutic bed both sides, adapter is to match with therapeutic bed, and can be fixed on the fixed mount of multiple therapeutic bed, gag lever post plays restriction, location and fixing, and lower limb ring is for immobilized patients shank.

One end of gag lever post is removably connected on adapter, and the other end inner side of gag lever post is provided with the lower limb ring being slidably connected with it, and lower limb ring is parallel with gag lever post and vertical with therapeutic bed; Lower limb ring can slide on gag lever post, regulates the height of lower limb ring according to the height of shank after couching, and lower limb ring is parallel with gag lever post and vertical with therapeutic bed, makes prostrate patient's shank in therapeutic bed through lower limb ring, and patient's shank is stuck in lower limb ring and is fixed; The position limitation of adapter and gag lever post the position of lower limb ring, thereby avoid patient's shank left and right pendulum position, further avoid pelvic cavity position chanP, improve the accuracy of pendulum position.

Gag lever post and adapter are marked with scale, can record height and the position of gag lever post on adapter of shank definite-time position bar first, thereby are fixed according to the data of record while making repetition radiotherapy, reproducible, improve radiotherapeutic effect.

Further, described gag lever post and adapter are slidably connected.Be slidably connected easy to operate, mobile if the position of gag lever post on adapter needs, avoid the trouble of installing again after dismounting, directly slide positioning instant can, easy to operate.

Further, described lower limb ring is open-close type lower limb ring.Open-close type lower limb ring is opened, closed procedure convenient.

Further, the inwall of described lower limb ring is provided with cushion course.Improve patient's comfortableness, avoid patient's shank to put into after lower limb ring fixing for a long time, hard material causes patient uncomfortable.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:

Fig. 1 is the schematic diagram of this utility model radiation lower limb fixing device embodiment;

Fig. 2 is the top view of Fig. 1.

The specific embodiment

As shown in Figure 1, this utility model radiation lower limb fixing device, comprise gag lever post 1 and the adapter 2 that is movably connected on therapeutic bed 4 both sides, one end of gag lever post 1 is removably connected on adapter 2, the other end inner side of gag lever post 1 is provided with the lower limb ring 3 being slidably connected with it, lower limb ring 3 is parallel with gag lever post 1 and vertical with therapeutic bed 4, and gag lever post 1 and adapter 2 are marked with scale; Described gag lever post 1 is slidably connected with adapter 2; Described lower limb ring 3 is opening and closing type lower limb ring 3; The inwall of described lower limb ring 3 is provided with cushion course.

In specific implementation process, adapter 2 is U-shaped folder, and U-shaped folder is fixed on therapeutic bed 4 by hold-down nut; The U-shaped folder upper surface of adapter 2 is provided with the groove mating with gag lever post 1, and gag lever post 1 can slide in groove, and the upper surface of U-shaped folder is provided with scale; Lower limb ring 3 comprises two semicircle hinge eyes, around pin joint open, closure; Cushion course in lower limb ring 3 adopts spongy layer.When use, patient is couched on therapeutic bed 4, by clamping the U-shaped of adapter 2 both sides due to therapeutic bed 4, the position of slip gag lever post 1 on adapter 2, open lower limb ring 3, make patient's both legs put into lower limb ring 3, close lower limb ring, then the height on gag lever post 1 and the position of gag lever post 1 on adapter 2 according to the fine position lower limb ring 3 of needs of patients radiotherapy, and record the scale on gag lever post 1, scale on adapter 2 and the position location of adapter 2 on therapeutic bed 4, in the time of next radiotherapy, only need to regulate according to the scale of record the position of lower limb ring 3 and gag lever post 1, can realize the object that repeatedly repeats radiotherapy same position.

Certainly, if adapter 2 adopts fixing head or other modes, lower limb ring 3 adopts that buckle-type is opened, closure, and the cushion course in lower limb ring 3 adopts layer of silica gel, froth bed all within protection domain.

For a person skilled in the art; do not departing under the prerequisite of this utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that this utility model is implemented.
