Description

    [0001] The present invention relates to a position maintenance device for knee arthroscopy,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a posture maintaining apparatus, and more particularly, to a posture maintaining apparatus for knee arthroscopic surgery for manipulating or maintaining a knee posture of a patient during arthroscopic knee surgery.

In recent years, as the population enjoying leisure and sports has increased, the accompanying sports injuries are increasing.

Among them, soft tissue injuries of the knee are the most frequently occurring sports traumas. Especially, the meniscus of the knee is the most damaged structure even in the knee joint.

The meniscus plate of the knee joint (hereinafter referred to as "meniscus plate") disperses the load applied to the knee joint to reduce the stress and impact transmitted to the articular cartilage, maintain the stability of the joint, It plays a very important role in nutrition and lubrication.

Therefore, in the medical field, the treatment of the meniscus is progressing steadily, and the most popular method is minimally invasive surgery using arthroscopy.

In such minimally invasive arthroscopic surgery, arthroscopic and cutting tools should be accessible to certain areas of the meniscus during surgery, and the patient's knee posture should be constantly manipulated and maintained.

At this time, the knee position of the patient is taken to be flexion, extension, internal rotation, external rotation, varus and valgus, which is performed by an assistant of the surgeon holding the patient's leg and directly exerting a force.

However, when the surgeon directly manipulates or maintains the knee posture of the patient, the surgeon experiences considerable physical exhaustion and fatigue, and if assisted by an inexperienced assistant, The need for correction can lead to prolongation of operation time and anesthesia time, and may lead to unintentional knee cartilage damage or damage to the knee and vascular tissue in the knee.

Accordingly, there is a demand for an auxiliary mechanism capable of fixing and releasing the leg joint of a patient to a specific posture position with a mechanical force. Korean Patent Registration No. 10-1353974 (2014.01.15) is disclosed as such an auxiliary mechanism have. Here, the upper brace is positioned above the lower limbs and supports the lower limb; A lower brace positioned below the lower joint to support the lower limbs; A lower support bracket connected to at least one side of the upper brace and the lower brace when the upper brace and the lower brace are pivoted about the center of the lower limb, Lt; / RTI >

However, the conventional lower limb assistive device has a limitation in that it is impossible to operate the upper and lower braces to rotate in one direction so that the knee of the patient can be flexed or stretched, but it can not be manipulated such as internal rotation, external rotation, .

In addition, the above-mentioned undergarment supporting auxiliary mechanism can not assemble and separate the upper brace and the lower brace and the fixing portion, and there is a limitation in disinfecting the individual members individually. Therefore, when such an undergarment auxiliary apparatus is used as a surgical tool, there may be a problem of hygiene, and there is a possibility that the surgical opening site of the patient during surgery is infected by bacteria.

To this end, the posture maintaining device includes a first fixing part 100, a second fixing part 200, and a connection part 300. The above-described posture maintaining device is exemplified for manipulating or maintaining the posture of the knee attached to the upper part of the leg, the lower part of the leg, or the foot of the patient. However, the present invention is not limited thereto. And the like.

One side of the first fixing part 100 is fixed to the surgical table T and the other side supports the upper part of the user's leg. The first fixing part 100 includes a cylindrical upper supporting member 110 provided with a space for accommodating an upper portion of the user's legs and a second upper supporting member 110 connected to the inside of the upper supporting member 120, And a fastening means 130 extending from the upper supporting member 110 and having one side fastened to the surgical table T, . Here, the first tightening means 121 is provided as a buckle, so that the upper fixing belt 120 is adjusted to a thickness of the user's upper leg. The clamping means 130 includes a clamp 131 at the lower end and the clamp 131 is fixed to the surgical table T with one side thereof clamped at the edge of the surgical table T. [ At this time, it is preferable that the upper support member 110 and the fastening means 130 are made of heat-resistant plastic so that they are not deformed or damaged by heat even when disinfected at a high temperature.

The second securing part 200 is spaced apart from the first securing part 100 to support the user's lower leg or foot. The second fixing part 200 includes a cylindrical lower supporting member 210 having a lower portion of the user's leg or a space for accommodating the feet and a lower supporting member 210 connected to the inside of the lower supporting member 210, And a lower fixing belt 220 having a second tightening means 221. The second fastening means 221 is provided with a buckle so that the lower fastening belt 220 is adjusted to the thickness of the lower leg or foot of the user. Further, the lower support member 210 is made of heat-resistant plastic so that it is not deformed or damaged by heat even when disinfected at a high temperature.

One side of the connection part 300 is connected to the first fixing part 100 in a rotationally connected state and the other side thereof is connected to the second fixing part 200 in a rotational connection. Here, the connection unit 300 is preferably configured such that a plurality of rods are rotatably connected to each other for a higher degree of rotational freedom. For example, as shown in FIG. 1, an upper connecting rod 310 having one side rotatably connected to the first fixing part 100, and a lower connecting rod 310 having one side rotatably connected to the second fixing part 200, And a lower connecting rod 320 rotatably connected to the connecting rod 310.
