Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a leg-supporting leg support, and more particularly, to a leg-supporting leg support for a surgeon, .

In general, osteotomy is a method of re-joining an angle and a position by cutting a bone, and is intended to correct the deformation of the bone or improve the joint function.

High-tibial osteotomy (HTO) during fracture (or osteotomy) is a method of correcting the legs by fracture of the legs with deformity (O-shaped) legs by degenerative arthritis, The weight of the knee, which is concentrated inside the knee joint, is distributed to the outside to reduce the pain and prevent artificial joint surgery.

Unlike artificial joints, it is preferred because it slows the progression of degenerative arthritis, preserves its own joints, and distributes the pressure exerted only on the inside of the joints to the external joints, thereby delaying the arthritis and cartilage damage as much as possible.

During the proximal osteotomy, the knee of the patient lying on the operating table is erected to fix the calf bone (tibia), fixed by the medical staff's hand, or fixed with a bundle of gauze or a pillow under the knee. (See Fig. 8)

One of the most important tasks in the proximal osteotomy is "stable cutting of the tibia." During the operation, a surgical instrument is used to apply a large force such as a drill, which may be difficult to fix in a posture by a person. Sterilized cloth, pillow, etc., it is not easy to adjust the angle of refraction of the knee.

That is, since it is not possible to stabilize the patient's leg with an unspecified arbitrary force or to adjust the angle of the patient optimally optimized for the operation of the medical staff, And it is easy to adjust the angle of the angle optimized for the medical staff, and a technique applicable to a surgical table already used is required.

In this regard, Korean Patent Registration No. 1336214 (Publication Date: Apr. 24, 2014) discloses a medical table in which controlled movement is performed and a method of using the same, The pulling mechanism that keeps the traction during the positioning of the operating table is used, but it is not easy to manufacture for the operating table itself and is expensive.

In addition, as a related art, a leg support is disclosed in Korean Registered Utility Model No. 0435467 (public announcement date: 2007.01.24), which is composed of a hexahedron body having a bottom face, four side faces and an upper face, The body is made of a sponge made of a rigid material and one side of the four sides is formed with a sprung support surface which forms an angle of 40 DEG to 70 DEG with respect to the bottom surface so as to support the sprung part of the user lying on the floor And the upper surface is a calf support surface extending from the thigh support surface to support the calf portion of the user and the imaginary extended surface of the calf support surface is in contact with the imaginary extended surface of the bottom surface in a range of 15 degrees or more and 35 degrees or less Respectively.

As another related art, Korean Utility Model Laid-Open Publication No. 2010-0004737 (published on May 10, 2010) discloses a leg support, which is provided with two seat portions on which an upper leg can be placed, And an angle adjuster attached to a lower surface of the body and having a shape inclined at a predetermined angle from the rear toward the front and injecting air into the body.

Although the above-described related arts can adjust the height or the angle of the leg support according to the user, it is not easy to use the angle adjusting means during the operation (while the leg is raised) There is also an impossible problem. Above all, it is inappropriate to use it in an operating room where sterilization is required.

Korean Registered Patent No. 1336214 (public announcement date: December 4, 2014) Korea Registered Utility Model Bulletin 0435467 (Notice: 2007.01.24.) Korea Public Utility Model Publication No. 2010-0004737 (Published on May 10, 2010)

As shown in FIGS. 1 to 4, the surgical assistance leg support 1 according to the first embodiment of the present invention is configured such that, in order to perform stable cutting when fracturing the tibia (tibia) The supporting member 100 is stably mounted on the operating table 2 and the supporting member 100 is rotatably engaged with the supporting member 100 to adjust the angle? And a fixing pin member 300 for fixing the angle formed between the supporting member 100 and the supporting member 200. [

This will be described more specifically.

The supporting member 100 is for stably mounting on the operating table 2. The supporting member 100 includes two side surfaces 110 and two side surfaces 110 facing each other with a predetermined gap therebetween, A top surface 120, and a bottom surface 130. The front surface 140, the rear surface 150, the top surface 120,

At this time, at least one of the front surface 140, the rear surface 150, the top surface 120 and the bottom surface 130 may be an open (imaginary) surface, desirable. This is to evenly distribute the stress to support the weight of the legs stably. However, in the present invention, the upper surface 120 and the rear surface 150 are opened for convenience of explanation.

In addition, the shape of the side surface 110 may be formed such that the width decreases toward the upper side. This is because the width of the lower surface 130 is wider than the width of the upper surface 120 so that the support member 100 stably stays on the surface of the operating table 2 and stays in a stable seating state.

The support member 100 includes an extended support portion 160 extended outwardly from a lower end portion of the support member 100 in contact with the operating table 2. This is for the support member 100 to be stably mounted on the operating table 2 and to place the x-ray cassette on the relatively opaque operating table 2 when the x-ray is taken and to stably support the supporting member 100 thereon.

The height of the rear surface 150 is higher than the height of the front surface 140 so that the top surface 120 forms an angle of 30 ° to 45 ° with the bottom surface 130. This is for the purpose of providing a space for adjusting the angle θ of rotation by the rotation of the receiving member 200 to be described later. (See Fig. 3 (b), and? Is between 30 and 45)
