Description

Four limbs mount for radiotherapy

Technical Field

The utility model relates to a radiotherapy auxiliary assembly technical field specifically is a four limbs mount for radiotherapy.

Background

At present, when a tumor patient receives radiotherapy, body position fixing technologies mainly comprise body surface line drawing, a vacuum pad, a thermoplastic film, foamed glue and the like. The radiotherapy fixing technology for patients with head and neck, chest and abdomen and pelvic tumors is mature, and the fixing effect can meet the requirement of accurate radiotherapy. However, the patients with tumor of four limbs are still mainly treated by the technique of drawing lines on the body surface or using vacuum pads because the patients do not have the limitation of special fixing devices and fixing techniques.

Because the two techniques have limited effect on fixing the body position of the patients with the tumor of the limbs, the patients with the tumor of the limbs can not move freely during each radiotherapy or can not keep the body position for a long time to move. The dose of a radiotherapy plan target area is different from the actual irradiation dose of a patient, and the irradiated volume and dose of the normal tissues around the target area can be increased due to the movement of the body position, so that the radiotherapy curative effect of the patients with the four-limb tumor is reduced, and the toxic and side effects of the radiotherapy are increased.

Fig. 1 to 4 are schematic structural views illustrating an embodiment of a four-limb fixing frame for radiotherapy, please refer to fig. 1 to 4, the main body of the four-limb fixing frame for radiotherapy includes a frame body 100, a limiting frame 200, a four-limb clamping member 300 and an adjusting knob 400.

The frame body 100 comprises a lying plate 110 and supporting legs 120 arranged at the bottom of the lying plate 110, wherein the lying plate 110 is used for a patient to lie flat for radiotherapy in the radiotherapy process. In this embodiment, a flexible mattress is laid on top of the lying plate 110. The comfort level of the radiotherapy of the patient is improved.

The limit frames 200 are used for horizontally limiting the four limbs of the patient lying on the lying plate 110, and the number of the limit frames 200 is four, and the limit frames respectively limit the two legs and the two arms of the patient. Specific four spacing frames 200 set up at the top of service creeper 110, surround with the top of service creeper 110 and form four limbs spacing groove H, and the four limbs of patient can correspond respectively insert and pass four limbs spacing inslot H, and the screw hole 210 that link up to four limbs spacing groove H is seted up at the top of spacing frame 200 for installation adjust knob 400, and the roof bottom of spacing frame 200 is provided with vertical guide bar 220, is used for guiding four limbs joint spare 300 to reciprocate.

Four limbs joint spare 300 is located four limbs spacing groove H, and its bottom has the arc wall 310 of looking mutually with service creeper 110 for with patient's four limbs laminating, and then fixed four limbs, and this four limbs joint spare 300's symmetry side has the guide way 320 of joint to guide bar 220 lateral wall, and the guide way 320 card is at the outer wall of guide bar 220, makes four limbs joint spare 300 can reciprocate along guide bar 220. Preferably, in the present embodiment, the limb clip 300 is made of PVC, and the inner wall of the arc-shaped groove 310 of the limb clip 300 is bonded with an elastic pad by an adhesive, so that the arc-shaped groove 310 reduces the pressure feeling on the limbs of the patient when the limb clip is attached to the limbs of the patient.

Adjust knob 400 is used for driving four limbs joint spare 300 to remove, and adjust knob 400's screw section knob is in screw hole 210 to run through to be connected with the top rotation of four limbs joint spare 300 in the four limbs spacing groove H, when adjust knob 400 during the relative screw hole 210 knob of adjust knob 400, four limbs joint spare 300 rises or descends along guide bar 220.

With reference to fig. 1 to 3, the specific use process of the limb fixing frame for radiotherapy according to the embodiment is as follows: when a patient is used for radiotherapy, the patient lies on the lying plate 110, the limbs (namely legs and arms) are inserted into the limb limiting grooves H correspondingly and penetrate through the limb limiting grooves H respectively, then the medical worker turns the adjusting knob 400, the screw rod part of the adjusting knob 400 rotates relative to the threaded hole 210, the adjusting knob 400 descends in the process of rotating relative to the threaded hole 210, and the limb clamping piece 300 is driven to move downwards along the guide rod 220 until the inner wall of the arc-shaped groove 310 of the limb clamping piece 300 is attached to the limbs of the patient.

After the patient is treated with radiotherapy, the adjusting knob 400 is turned again (opposite to the previous rotating direction), so that the limb clamping member 300 is retracted to the original position, and then the limbs are pulled out from the limb limiting groove H.

Referring to fig. 4, in the present embodiment, a headrest 500 is detachably disposed on the head of the lying plate 110 for a patient to put a pillow thereon, and the headrest 500 can be detached from the head of the lying plate 110 to facilitate cleaning of the headrest 500, specifically, a headrest placing groove 110a is disposed on the side wall of the head end of the lying plate 110, and sliding grooves 110b are disposed on the symmetrical sides of the headrest placing groove 110a, and a sliding bar 510 is disposed on the outer side of the headrest 500 and is snapped into the sliding groove 110b, so that the headrest 500 can be detached by sliding out along the sliding groove 110b when the headrest 500 is detached.

While the invention has been described above with reference to an embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, as long as there is no structural conflict, the various features of the disclosed embodiments of the present invention can be used in any combination with each other, and the non-exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation.
