Abstract

The utility model discloses a position fixer belongs to the medical health field to solve the problem that the repeatability of the low limbs position that current fixed equipment exists becomes poor. A body position fixer comprises a bottom plate, wherein a support is arranged on the bottom plate, the support is formed by movably connecting a long plate and a short plate, and the included angle between the long plate and the short plate is 90-130 degrees. The utility model discloses according to the ergonomic principle, with fixed shank of length, short slab and sole, the low limbs tumour radiotherapy patient who uses this product is getting the advanced position of prone position foot, and the mark line when combining the patient location jointly fixes patient's low limbs position, strengthens the fixed compactness of position and the repeatability of follow-up pendulum position treatment. And the subconscious movement in the radiotherapy process is reduced.

Description

Body position fixer

Technical Field

The utility model belongs to the medical health field, concretely relates to position fixer.

Background

With the development of radiotherapy technology, the therapeutic indications can be expanded to lower limb parts such as lower limb soft tissue sarcoma, bone metastasis tumor, knee joint pigmentation, villous nodular synovitis and the like, and when a patient with lower limb tumor is subjected to precise radiotherapy, the target dose of a tumor target area needs to be increased and the irradiated dose of surrounding normal tissues and organs at risk needs to be reduced as far as possible. However, no matter the patient adopts the advanced supine position or the advanced prone position of the foot, the fixation is difficult, the crus or soles of the patient are easy to rotate involuntarily to the left and the right, and the remote monitor cannot distinguish the slight movement, so that the patient is in the most comfortable, relaxed and natural position, which is a necessary condition for improving the consistency, the repeatability and the accuracy in the subsequent treatment execution process.

In tumor radiotherapy, the head and neck and the chest and abdomen are respectively fixed by a head membrane, a head-neck-shoulder membrane, a vacuum body membrane or a net membrane, and the fixing devices are widely applied, and the radiotherapy of lower limb tumors and the like does not have a mature fixing device. At present, the following fixing methods are often adopted in clinical work: vacuum pad fixation, foam pad fixation, reticular membrane fixation, and T-shaped sole fixation. All accurate planning and careful positioning are useless without taking accurate positioning as a basis. Only by setting the precise field in a proper posture, the subsequent treatment effect can be ensured. However, for some patients, the body position fixing plate can be used to make the repeatability of the body position of the lower limb worse by using the existing fixing equipment only because of the involuntary movement and steering caused by the physiological factors of bones or muscles such as the lower limb, the sole and the like, and the positions of the lower limb or the sole which are swung for each treatment are different.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a position fixer to solve the problem that the repeatability of the low limbs position that current fixed equipment exists becomes poor.

The utility model discloses technical scheme as follows: a body position fixer comprises a bottom plate, wherein a support is arranged on the bottom plate, the support is formed by movably connecting a long plate and a short plate, and the included angle between the long plate and the short plate is 90-130 degrees.

As a further improvement, the bottom plate is provided with a first groove and a second groove, the lower ends of the long plate and the short plate are respectively provided with a first convex edge and a second convex edge, and the first convex edge and the second convex edge are respectively clamped into the first groove and the second groove.

As a further improvement of the utility model, the second groove is a plurality of parallel arrangements.

As a further improvement of the present invention, the second grooves are 12.

As a further improvement of the utility model, the long plate and the short plate are connected through a pin shaft.

As a further improvement of the utility model, the middle-to-upper position of the short plate is provided with a buckle belt.

The utility model discloses an innovation point is as follows: the design is composed of a carbon fiber bottom plate, a long plate, a short plate and a magic tape buckle belt, and the long plate and the short plate are connected through a pin shaft. The height and the angle of the bracket can be adjusted according to the natural bending of the lower limbs, the shanks and the soles of different patients, and the bracket can be repeatedly used.

The long and short plates are filled with shaping sponge to fix the crus and the soles according to the ergonomic principle, and the lower limb tumor radiotherapy patient using the product jointly fixes the lower limb parts of the patient in the advanced position of the foot in the prone position by combining the marking lines when the patient is positioned, so that the tightness of the position fixation and the repeatability of the subsequent positioning treatment are enhanced. And the subconscious movement in the radiotherapy process is reduced.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in the figure, the body position fixator comprises a bottom plate 1, wherein a support is arranged on the bottom plate 1, the support is formed by movably connecting a long plate 2 and a short plate 4, and the included angle between the long plate 2 and the short plate 4 is 90-130 degrees. Be equipped with first recess 11 and second recess 12 on the bottom plate 1, the lower extreme of long board 2 and short slab 4 is equipped with first chimb 21 and second chimb 22 respectively, and first chimb 21 and second chimb 22 are gone into respectively in first recess 11 and the second recess 12 to the card. The second grooves 12 are arranged in parallel. The long plate 2 and the short plate 4 are connected through a pin shaft 3. The middle upper position of the short plate 4 is provided with a buckle belt 5.

Example 1

The bottom plate is made of carbon fibers, the length of the bottom plate is 60cm, the width of the bottom plate is 20cm, the thickness of the bottom plate is 2.5cm, 12 grooves are hollowed in the middle, the distance between the grooves on the two sides is 16cm, the interval distance between every two grooves is 1.5cm, the width of the middle of each groove is 1.5cm, and the depth of each groove is 1 cm. The width of a bending support formed by the long plate and the short plate is 16cm, the short side is 25cm, the long side is 45cm, and the diameter of the pin shaft is 10 cm.

The long plate and the short plate are filled with shaping sponge. The long plate is connected with the short plate through a pin shaft, and the lower end of the long plate is provided with a convex edge with the diameter of 1.5cm and the length of 1 cm. The convex edge is matched with the groove in shape, and the convex edge at the lower end of the long edge and the short edge of the support can be just clamped into the groove of the carbon fiber base plate. And the lower end of the short side can be adjusted to be inserted into different positions of the groove, so that the angle and the height of the bending support can be changed.

When the foot fixing device is used, the lower leg and the foot surface of a prone position of a patient are embedded into the support, and the hook-and-loop fasteners on the short sides can play a role in fixing the sole after being bonded with the primary and secondary surfaces.
