Description

A foot immobilization device for leg tumor radiotherapy

technical field

The utility model relates to a fixing device for leg tumor radiotherapy, which can be used for fixing and positioning legs and feet during the leg tumor radiotherapy process, and belongs to the application in clinical work of tumor radiotherapy.

Background technique

At present, the fixation method for radiotherapy of leg tumors is as follows: the patient puts his legs together and straightens, lies flat on the treatment bed, and fixes the patient with a thermoplastic body film. When three-dimensional conformal radiotherapy and intensity-modulated radiotherapy are applied to leg tumors, multi-angle and multi-field irradiation will inevitably penetrate the normal tissues of the healthy side and cause unnecessary radiation damage. Due to the requirement of repeated positioning, the thermoplastic body film must fix the two legs on the positioning frame, so that in order to make the dose distribution of the tumor area meet the clinical requirements during radiotherapy, multi-field irradiation is required, so a large number of rays will also pass through the uninjured leg , causing unnecessary radiation damage.

Contents of the invention

The technical problem to be solved by the utility model is to provide a foot fixation device for leg tumor radiotherapy, so as to reduce or avoid the aforementioned problems.

In order to solve the above technical problems, the utility model proposes a foot fixing device for radiotherapy of leg tumors, the foot fixing device is slidably arranged on a leg support frame, wherein the leg support frame It includes a slope section, a horizontal section and a support section fixedly connected together, the foot fixing device is slidably arranged on the horizontal section through a sliding seat, and the foot fixing device has a vertical fixing arrangement On the foot baffle on the sliding seat, a toe fixing groove plate is fixedly arranged on the upper part of the foot baffle.

Preferably, the toe fixing groove plate has at least 4 grooves.

Because the utility model adopts the above-mentioned technical scheme, during the treatment process, by adjusting the position of the foot fixing device, not only can the patient's treatment position be repeated accurately and individually, but also the radiation can avoid the tissue on the healthy side, so as to treat the tumor on the affected side. Precise irradiation treatment effectively protects normal tissue on the healthy side.

Description of drawings

The following drawings are only intended to illustrate and explain the utility model schematically, and do not limit the scope of the utility model. in,

Fig. 1 shows a schematic structural view of a foot immobilization device for leg tumor radiotherapy according to a specific embodiment of the present invention.

Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation of the utility model is now described with reference to the accompanying drawings. Wherein, the same parts adopt the same reference numerals.

Referring to FIG. 1 , it shows a foot fixing device 3 for radiotherapy of leg tumors according to a specific embodiment of the present invention. The foot fixing device 3 is slidably arranged on a leg support frame 2 superior. The leg support frame 2 is fixedly arranged on a base 1 , of course, those skilled in the art should understand that in specific applications, the leg support frame 2 can be fixedly arranged on any suitable structure.

The leg support frame 2 includes a slope section 21 , a horizontal section 22 and a support section 23 fixedly connected together, and a foot fixing device 3 is slidably arranged on the horizontal section 22 .

Specifically, the foot fixing device 3 is slidably arranged on the horizontal section 22 through a sliding seat 4 .

The foot fixing device 3 has a foot baffle 31 vertically fixedly arranged on the sliding seat 4, and the upper part of the foot baffle 31 is fixedly provided with a toe fixing groove 32, and the foot baffle 31 and the toe fixing groove are shown in the figure. 32 is the integral structure. A scale (not shown in the figure) is provided on the horizontal section 22 , and the scale can be arranged on the front of the horizontal section 22 or on the side of the horizontal section 22 . To facilitate leg immobilization, in a preferred embodiment, the horizontal section 22 is concave along its length to facilitate conforming to the contours of the patient's leg. There are multiple grooves 33 on the toe fixing groove plate 32, so that the patient's toes are placed in the grooves 33 for fixing; The four toes of the patient are stuck in the groove 33, and the patient's big toe remains on the outside of the toe fixing groove plate 32 to get final product.

When in use, the patient can lie supine on the treatment bed, with the thighs obliquely placed on the slope section 21 and the lower legs placed on the concave horizontal section 22 . Record the scale line value corresponding to the calf marking line after the first calf placement. Then the sliding foot fixing device 3 is close to the patient's foot plate, and the patient's toes are fixed in the groove 33 of the toe fixing groove plate 32, thereby fixing the patient's foot. And record the scale line value corresponding to the foot fixing device 3 . Through the above two-step operation, it can ensure good repeatability of positioning during treatment and between treatment sessions, and can repeat the patient's treatment position individually.

Because the utility model adopts the above-mentioned technical scheme, during the treatment process, by adjusting the position of the foot fixing device, not only can the patient's treatment position be repeated accurately and individually, but also the radiation can avoid the tissue on the healthy side, so as to treat the tumor on the affected side. Precise irradiation treatment effectively protects normal tissue on the healthy side.

The above descriptions are only illustrative specific implementations of the present utility model, and are not intended to limit the scope of the present utility model. Any equivalent changes, modifications and combinations made by those skilled in the art without departing from the concept and principle of the present utility model shall fall within the scope of protection of the present utility model.
