Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lateral position abduction retainer for maintaining a patient in a lateral position and at the same time maintaining an abducted position of an affected limb.

[0002]

2. Description of the Related Art In the field of orthopedic surgery, there are a large number of patients who require rotational acetabular osteotomy or hip replacement surgery. These patients are at risk of dislocation due to flexion, adduction, and internal rotation of the operated limb during periods of inadequate limb muscle recovery following surgery. Requires maintenance of dislocations. Conventionally, for the purpose of maintaining this abduction, an abduction pillow, which is a trapezoidal pillow that is fixed between the patient's legs, is used to maintain the abduction of the affected limb during supine position. In addition to the affected limb, the healthy limb on the healthy side was also fixed to an abduction pillow with a band or the like.

[0003] On the other hand, patients who are forced to stay in bed for a long period of time are required to change their posture easily to prevent bedsores and alleviate mental and physical pain. Therefore, it is desirable to adopt not the supine position but the lateral position, which has a relatively high degree of freedom in the body position, even for patients who have undergone acetabular rotation osteotomy or artificial hip joint replacement.

[0004]

However, when an abduction pillow is used, not only the affected limb but also the healthy limb of the patient is fixed to the abduction pillow by a band or the like. However, there are some problems described below with respect to the patient being in a lateral position. Generally, when a patient who needs to hold the hip joint in abduction position is in a lateral position, the affected limb is placed above the abduction pillow and the healthy limb is placed below the abduction pillow. Therefore,
Since the weight of the affected limb and the abduction pillow is applied to the healthy limb disposed below the abduction pillow, the healthy limb receives pressure and causes pain. In addition, since both lower limbs are fixed to the abduction pillow by a belt or the like, there is a sense of being tightened. In addition, the abduction pillow fixes the patient's lower limb as described above,
In the lateral position, the posture of the lower limb becomes unstable.

[0005] Due to the above problems, it is not easy for a patient to maintain a prone position for a long time, and the use of an abduction pillow has the drawback that physical and mental discomfort is caused by taking a prone position. ing. Therefore, an object of the present invention is to eliminate the need for the patient's lower limb fixation, increase the degree of freedom of the healthy limb, and remove the feeling that the affected limb is tightened, so that the patient can comfortably stay in a prolonged lateral position. Is to provide a supine abduction cage capable of holding the abductor in an abduction position.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned object, the present invention comprises a supporting leg and a leg rest provided on an upper portion of the supporting leg, and a patient's foot is provided below the leg rest. An object of the present invention is to provide a lateral recumbent abduction cage characterized in that a space for inserting one leg is formed. In a preferred embodiment of the lateral position holder of the present invention, the leg rest has a groove-shaped surface with a concave central portion.

[0007] In another preferred embodiment of the lateral position holder according to the present invention, the leg rest is inclined. In another preferred embodiment of the lateral position holder of the present invention,
The support leg includes a plurality of leg members. Further, in still another preferred embodiment of the lateral position retainer of the present invention, the leg mounting portion includes an upper column member disposed to face the upper column member, and the upper column member is supported between the upper column member and the upper column member. A cloth portion having a width larger than the interval between the members.

In the above embodiment, preferably, the support leg includes a plurality of leg members supporting the upper column member, and the leg members supporting different upper column members are connected by a cross member therebetween. ing. More preferably, each of the upper column member and the leg member has a circular cross section. In the preferred embodiment described above, it is preferable that the leg member is extendable and contractible.

[0009] Preferably, the lateral position holder of the present invention includes a back support having a support surface abutting on the patient's back, and a support for holding the support surface at a predetermined angle with respect to a horizontal plane. A back holder comprising a base supporting the back support may be further provided. In this case, preferably, the back support portion of the back holder includes a peripheral column member assembled in a predetermined shape, and a support surface formed of a cloth portion whose edge is supported by the peripheral column member. It becomes. More preferably,

[0010] According to the lateral position abduction cage of the present invention, the leg rest can maintain a stable posture by the support leg, and the stable leg rest provided on the upper part of the support leg. By configuring to form a space under which one of the patient's legs can be inserted, the patient places one leg on the leg rest and the other in the space provided below the leg rest. It is possible to maintain a stable lateral position by inserting the legs, and to prevent the weight of one leg of the patient placed on the leg rest from being applied to the other leg. Further, the patient can freely move the other leg inserted therein in the space.

Further, since the leg rest has a groove-shaped surface with a concave central portion, the patient's leg can be stably held on the leg rest without using restraining means such as a band. As a result, since the leg rest is inclined, the lower limb, that is, the leg of the patient can be reliably held in the abducted position when the patient takes the lateral position. By configuring the leg rest portion with the cloth portion supported between the upper column members arranged opposite to each other, the patient's leg may be stuffy, which may cause a problem when the patient's leg is put on the leg rest portion for a long time. In addition, the discomfort caused by the leg is alleviated, and the cloth portion has a slack larger than the width of the outer frame, so that the leg naturally fits the shape of the leg, thereby preventing the leg from slipping off.

Further, by configuring the leg members to be extendable and contractible, it is possible to adjust the height of the leg rest portion according to the patient. Further, by providing the back holder for holding the back of the patient, the patient can maintain the lateral position more stably for a long time, and further, the inclination angle of the support surface of the back support of the back holder.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a lateral abduction holder according to the present invention. FIG. 1 is a perspective view showing a first embodiment of a lateral position abduction retainer of the present invention for maintaining an abducted position of a diseased limb while maintaining a patient in a lateral position. The lateral abduction retainer 10 shown in FIG.
It is composed of a support leg 12 and a substantially square leg mounting portion 14.

The leg rest 14 is provided on the support leg 12 and has an upper surface 16 having a groove-like surface having a recess at the center and raised at both ends. The upper surface 16 of the leg rest 14 is inclined such that one end is higher than the other end. The leg rest 14 is adapted to rest one leg (affected limb) of the patient's lower leg on the grooved surface. Furthermore, the inclined upper surface 16 of the leg rest allows the abduction of the affected limb to be maintained more naturally. Also, the upper surface 1 of the leg rest 14
Since the limb 6 has a groove shape, the affected limb placed on the leg rest 14 is prevented from dropping from the upper surface 16, so that the affected limb of the patient can be placed on the leg rest 14 with minimum restraint.
Can be held.

The support legs 12 for supporting the leg rests 14 from below have rectangular grooves 18 penetrating the wall surfaces at both ends under the rectangular base member, and the walls on both sides of the rectangular grooves 18 are provided. It is formed by providing an opening 20 that penetrates. In this manner, four independent leg members 22 arranged at the four corners are formed below the leg mounting portion 14. However, the support leg portion 12 may be configured by attaching separately formed flat leg members 22 to the four lower corners of the leg rest portion 14.

By supporting the leg rest 14 at the four corners with the leg members 22 as described above, the leg rest 14 can maintain a stable posture. Since a space is formed between each leg member 22, the other leg (healthy limb) of the patient can be inserted into the space,
The inserted healthy limb can be freely moved in the space. Further, the leg rest 14 is supported by the leg member 22, and the weight of the affected limb placed on the leg rest 14 is applied to the healthy limb inserted into the space formed below the leg rest 14. Never. Therefore, the compression of the healthy limb due to the weight of the affected limb which occurs when the conventional abduction pillow is used to take the lateral position is avoided.

Also, as shown in FIG.
Of the support legs 22 can be configured to be extendable and contractible, that is, the length thereof can be adjusted. For example, as shown in FIG. 1, by attaching a second leg member 26 having a long groove 24 penetrating in the thickness direction to a leg member 22 as a first leg member by a fastener 28 such as a screw. Achieved. For adjusting the length, such as a method of nesting the second leg member in the leg member and sliding it, a method of fixing one of the plurality of through holes provided in the second leg member to the leg member with a pin or the like. Other arbitrary mechanisms can be employed.

By configuring the leg member 22 to be extensible in this manner, it is possible to change the height of the upper surface 16 of the leg rest 14 for holding the affected limb in accordance with the patient's body type. Become. Further, it is also possible to change the inclination angle of the leg rest 14 with respect to the horizontal plane. The lateral abduction cage 10 shown in FIG. 1 includes a back support 32 having a support surface 30 for supporting the back of a patient, and a back support 32.
And a base 34 for supporting the back. The back support 32 has an opening 38 at its center.
Is provided to enhance the breathability of the patient's back.
The base portion 34 holds the support surface 30 of the back support portion 32 at a predetermined angle with respect to a horizontal plane, and preferably has a triangular shape having, as one apex angle, the angle that the support surface 30 should make with the horizontal plane. 2 is a plate-like member as shown in FIG. The angle formed by the support surface 30 of the back support 32 with respect to the horizontal plane is preferably an angle slightly smaller than 90 degrees.

By providing the back holder 36, the patient can hold the back on the support surface 3 of the back support 32 of the back holder 36.
Since it can be brought into contact with zero, it is possible to maintain the lateral position more physically and comfortably. FIG. 2 is a perspective view showing a second embodiment of the lateral abduction holder according to the present invention. Referring to FIG. 2, the lateral abduction holder 50 includes a support leg 52 and a leg rest 54 provided on the support leg 52, as in FIG. 1.

The leg rest 54 of the lateral abduction holder 50 shown in FIG. 2 has two upper column members 56 arranged in parallel to face each other, and a cloth portion which is supported, attached and extended between them. 58. As in FIG. 1, the leg rest 54 is inclined such that one end is higher than the other end. In addition, the cloth portion 58 supported between the two upper column members 56 has a width larger than the interval between the upper column members 56, and is slack and curved downward.
Its surface has a groove shape.

The lateral abduction holder 50 shown in FIG.
With the structure as described above, the following advantages and effects are further provided in addition to the advantages and effects of the lateral abduction holder 10 in FIG. 1. First, since the surface for supporting the legs of the leg rest 54 is constituted by the cloth 58,
When the patient's affected limb is placed on the cloth portion 58, the cloth portion 58 takes a groove-like shape that naturally fits the shape of the patient's leg, so that the affected limb can be reliably held.

Further, since the cloth material used for the cloth portion 58 has air permeability and moisture absorption, even when the cloth material is placed on the surface of the leg rest portion 54 for supporting the legs for a long time, sweating of the affected limb is prevented. It is possible to suppress the discomfort caused by the sweat and to prevent the discomfort caused by the sweat, and it is easy to clean or replace the surface of the leg rest 54 when the surface becomes dirty due to the sweat or the like. Further, the surface of the leg rest portion 54 of the lateral abduction holder 50 shown in FIG. 2 deforms more flexibly than the leg rest portion 14 whose surface is formed of a rigid member as shown in FIG. be able to. Therefore, there is an additional advantage that the patient hardly feels the sense of restraint of the affected limb.

The leg rest 54 is provided with two upper column members 5.
6 are respectively supported from below by columnar leg members 60. In FIG. 2, the leg members 60 extend in a direction substantially perpendicular to the horizontal plane, but may be inclined with respect to the horizontal plane, and the leg members 60 need not be parallel to each other. However, from a mechanical point of view, it is preferable to take a symmetrical shape with respect to a vertical plane extending in the longitudinal direction (the direction in which the upper column member 56 extends).

Adjacent leg members 60 supporting the same side ends of different upper post members 56 are spaced transversely (perpendicular to the longitudinal direction) to maintain spacing and provide stable support. Are connected by a transverse member 62 extending to Further, each leg member 60 is moved by a mechanism described below, as shown in FIG.
Is configured to be able to expand and contract like the leg member 22 shown in FIG.

The upper column member 56 and the leg member 60 of the lateral abduction holder 50 are, in the preferred embodiment shown in FIG. 2, formed of elongated column members having a circular cross section. However, as the upper column member 56 and the leg member 60, a hollow or solid columnar member having an arbitrary cross section such as a triangle, a quadrangle, a polygon, and an ellipse can be used.

As described above, since the supporting leg 52 is composed of the columnar leg member 60, a large space for inserting a patient's healthy limb can be formed below the leg rest 54, so that the patient Can freely move the healthy limbs in the space, greatly reducing physical and mental distress. Next, with reference to FIG. 3 which is the same as FIG. 2 except that the cloth portion 58 is removed from the lateral abduction holder 50 of FIG. 2, the lateral abduction holder 50 shown in FIG. The mechanical features will be described.

As shown in FIG. 3, the length of the upper column member 56 can be adjusted to extend and contract. For example,
As shown in FIG. 3, the upper column member 56 is configured so that the adjustment length portion 66 can be telescopically accommodated in the accommodation portion 68 having a larger diameter by loosening the tightening of the adjustment grip 64. In this case, after adjusting the entire length of the upper column member 56 to a desired length, the length is maintained by tightening the adjustment grip again. Such a length adjusting method is a known technique and will not be described in further detail. Of course, any other suitable mechanism that allows for length adjustment can be used.

Next, a mechanism for adjusting the length of the leg member 60 will be described. The leg member 60 includes a first leg member 70 and a second leg member 72. The first leg member 70 has a hollow structure, and has an inner hole having an inner diameter slightly larger than the outer diameter of the second leg member 72 inside thereof. That is, the first leg member 70 has a pipe shape. The first leg member 70 is provided with a plurality of diametrically-paired through holes 74 continuously in the length direction.

On the other hand, the surface of the second leg member 72 is provided with a projection 76 having a spherical surface paired in the diameter direction. In the embodiment of the lateral abduction holder shown in FIGS. 2 and 3, a pair of protrusions 76 is provided, but a plurality of pairs of protrusions may be provided. This projection 76
Is urged by urging means such as a leaf spring or a coil spring, and normally protrudes from the surface of the second leg member 72. It is to be accommodated.

By pressing the projection 76 of the second leg member 72 thus configured, the second leg member 72 is moved to the first leg member 70.
The second leg member 72 is attached to the first leg member 70 by projecting the projection 76 of the second leg member 72 from the through hole 74 of the first leg member 70 at a desired position. By changing the position at which the protrusion 76 of the second leg member 72 projects from the through hole 74 of the first leg member 70, the leg member 60 can be adjusted to have a desired length.

Further, a cylindrical second leg member 72 having a pair of through holes in the diameter direction is inserted into the inner hole of the first leg member 70, and the first leg member 70 and the second leg member 72 are inserted. The second leg member 72 may be attached to the first leg member 70 by inserting a fixing pin through both of the through holes. By changing the position of the hole into which the fixing pin is inserted out of the plurality of through holes 74 provided in the first leg member 70, the entire length of the leg member 60 can be adjusted.

Of course, it is also possible to use the slide-type length adjusting mechanism described for the upper column member 56. It is equally possible to use any other suitable mechanism for adjusting the length. Cross member 62 interconnecting adjacent leg members 60 in the cross direction
Has a connecting portion 78 having a circular through opening at both ends thereof, which has a diameter slightly larger than the circular cross section of the leg member 60 (specifically, the first leg member 70). . By inserting and penetrating the leg members 60 into the circular through openings, and attaching and fixing the connecting portions 78 to the leg members 60 with the fasteners 80, the intervals between the leg members 60 can be maintained at a constant interval. Therefore, the lateral abduction holder 50 can maintain a stable posture. As the fastener 80, it is preferable to use a screw which can be fastened without using a tool having a grip portion as shown in FIG.

By using the cross member 62 having the connecting portion 78 having the circular through openings at both ends, the fastener 80 is removed or loosened to rotate the leg member 60 within the circular through opening. As shown in FIG. 4, the lateral abduction holder 50 can be folded, so that a large space is not required for storage when not in use. Further, as shown in FIG. 3, since the protruding portion 76 protrudes from the surface of the first leg member 70, when the cross member 62 is attached to the leg member 60 and the fastener 80 for fixing is removed, Inadvertent dropping or movement of the cross member 62 is prevented.

Preferably, the cloth portion 92 supported at 0 has an extension 94, which can be used to prevent displacement of the back retainer 82 by laying the extension 94 on the floor and under the patient. it can. By forming the support surface 84 with the cloth portion 92, air permeability and moisture absorption are ensured, and discomfort such as stuffiness caused by sweat perceived by the patient is reduced, which helps to maintain the lateral position for a long time.

The back support 86 is rotatably held by a base 88, and the support surface 84 of the back support 86 can be inclined at a desired angle with respect to a horizontal plane.
By making the inclination angle of the support surface 84 changeable,
The patient can maintain a more comfortable posture. Base 8
8 is preferably constituted by a pipe-shaped column member as shown in FIG. Peripheral column member 9 of back support portion 86
By configuring the 0 and the base with a pipe-shaped column member, as shown in FIG. 6, it becomes possible to fold and reduce the space required for storage.

The base 88 is provided with a plurality of through holes 96. The through holes 96 are formed by screwing an arm 98 rotatably attached to the side of the peripheral column member 92 of the back support 86 into the base 88. It is used when fastening with a fastener 100 such as. By changing the position of the through hole 96 used when the arm 98 is fixed to the base 88, the angle formed by the support surface 84 of the back support 86 with respect to the horizontal plane can be adjusted. It goes without saying that other known angle adjusting mechanisms can be used.

As a cloth used as a component of the lateral abduction cage 50 of the present invention shown in FIG. 2, a cloth made of natural fibers such as cotton and silk and synthetic fibers can be used. Further, other materials such as artificial leather can be used in place of the cloth as long as they have appropriate air permeability and flexibility.
