Abstract
The utility model discloses a leg fixing device for leg tumor radiotherapy which is composed of a holder and a leg supporting rack which is fixed to and supported by the holder, wherein the leg supporting rack contains a slope section, a horizontal section and a supporting section, the three of which are fixedly connected together; wherein the horizontal section is slidingly provided with a leg fixing device. The technical solution of the utility model allows an accurate and personalized repetition of patient's treatment posture by adjusting position of the leg fixing device, and the ray emitted can avoid contralateral tissues and give affected tumor an accurate irradiation treatment, thus effectively protecting contralateral normal tissues.
Description
Technical Field
The utility model relates to a fixing device for shank tumour radiotherapy can be used to shank tumour radiotherapy in-process and carries out fixed position to shank and foot, belongs to the application in tumour radiotherapy clinical work.
Background
The current clinical fixing method for radiotherapy of leg tumors is as follows: the patient is put on the treatment bed with the legs closed and extended, and fixed by the thermoplastic film. When three-dimensional conformal radiotherapy, intensity modulated radiotherapy and the like are carried out on leg tumors, multi-angle and multi-field irradiation is applied, and unnecessary radiation damage is inevitably caused by normal tissues of healthy legs. Due to repeated positioning requirements, the two legs must be fixed on the positioning frame by the thermoplastic film, so that in radiotherapy, in order to make the dose distribution of a tumor region meet the clinical requirements, multi-field irradiation is needed, and therefore a large amount of rays can also penetrate through the healthy side legs, and unnecessary radiation damage is caused.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a shank fixing device for shank tumour radiotherapy to reduce or avoid the aforementioned problem.
In order to solve the technical problem, the utility model provides a shank fixing device for shank tumour radiotherapy, this shank fixing device comprises a base and the shank support frame of fixed stay on this base, wherein, the shank support frame includes a slope section, a horizontal segment and a support section that fixed connection is in the same place, the slidable is provided with a foot fixing device on the horizontal segment.
Preferably, the foot fixing device is slidably disposed on the horizontal section through a sliding seat, the foot fixing device has a foot baffle vertically and fixedly disposed on the sliding seat, and a toe fixing groove plate is fixedly disposed on the upper portion of the foot baffle.
Preferably, a graduated scale is arranged on the horizontal section.
Preferably, the horizontal section is concave along its length.
The utility model discloses owing to adopted above-mentioned technical scheme, in the treatment process, through adjusting foot fixing device's position, not only can be accurate, individualized repeated patient treatment position, the healthy side tissue can be avoided to the ray moreover, carries out the accurate treatment of shining to the tumour of suffering from the side to healthy side normal tissue has been protected effectively.
Drawings
The drawings are only intended to illustrate and explain the present invention and do not limit the scope of the invention. Wherein,
fig. 1 is a schematic structural diagram of a leg fixing device for leg tumor radiotherapy according to an embodiment of the present invention.
Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
Referring to fig. 1, there is shown a leg fixing device for radiotherapy of leg tumor, which is composed of a base 1 and a leg support frame 2 fixedly supported on the base 1, according to an embodiment of the present invention.
The leg support frame 2 comprises a slope section 21, a horizontal section 22 and a support section 23 which are fixedly connected together, and the horizontal section 22 is slidably provided with a foot fixing device 3.
Specifically, the foot fixing device 3 is slidably disposed on the horizontal section 22 through a sliding seat 4.
The foot fixing device 3 has a foot blocking plate 31 vertically fixed on the sliding seat 4, a toe fixing groove plate 32 is fixed on the upper part of the foot blocking plate 31, and the foot blocking plate 31 and the toe fixing groove plate 32 are shown as a whole structure. The horizontal section 22 is provided with a scale (not shown in the figure), and the scale can be arranged on the front surface of the horizontal section 22 or on the side surface of the horizontal section 22. To facilitate leg immobilization, in a preferred embodiment, the horizontal segment 22 is concave along its length to facilitate conformance to the contour of the patient's leg. The toe fixing groove plate 32 is provided with a plurality of grooves 33, so that the toes of the patient can be placed in the grooves 33 for fixing; in the illustrated embodiment, the four recesses 33 are provided, and four toes of a patient having generally five toes can be caught in the recesses 33 while the thumb of the patient is left outside the toe fixing groove plate 32.
When in use, a patient can lie on the treatment bed with the thigh inclined on the slope section 21 and the shank on the concave horizontal section 22. And recording the scale mark value corresponding to the mark line of the lower leg part after the lower leg is placed for the first time. The foot fixing means 3 is then slid against the patient's foot plate to fix the patient's toes in the grooves 33 of the toe fixing groove plate 32, thereby fixing the patient's feet. And records the corresponding scale line values of the foot fixing device 3. Through the two steps of operation, the positioning repeatability between the middle treatment and the treatment in times can be ensured to be good, and the treatment body positions of the patients can be individually repeated.
The utility model discloses owing to adopted above-mentioned technical scheme, in the treatment process, through adjusting foot fixing device's position, not only can be accurate, individualized repeated patient treatment position, the healthy side tissue can be avoided to the ray moreover, carries out the accurate treatment of shining to the tumour of suffering from the side to healthy side normal tissue has been protected effectively.
The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes, modifications and combinations that may be made by those skilled in the art without departing from the spirit and principles of the invention should be considered within the scope of the invention.
