Abstract: In order to provide an external corrective appliance that corrects spinal deformity through operation from outside of the body during implementation of correction and fusion of the spinal deformity using a spinal deformity correction and fusion system to improve correction force, to easily attain the correction intended by an operator, and to eliminate complexity of correction and fusion surgery implemented using the spinal deformity correction and fusion system, thereby reducing burden on the patient, the external corrective appliance includes: shaft members removably attached to corresponding right and left screw members in a pair fixed to the one vertebra, and extending toward the outside of the body of the patient; and a lateral arm member coupled to the shaft members in a pair outside the body of the patient.

Abstract: To provide a corrective appliance capable of properly assisting in correction of spinal deformity by a spinal deformity correction and fusion system while limiting damage on a rod member when the spinal deformity is subjected to correction and fusion by the spinal deformity correction and fusion system. A corrective appliance includes: a clamp member to be attached detachably to a screw member, for example, and to be arranged close to the screw member; and an auxiliary rod member to be attached detachably to the clamp member and to be used for correcting spinal deformity. This allows the corrective appliance to properly assist in correction of spinal deformity by a spinal deformity correction and fusion system while limiting damage on a rod member when the spinal deformity is subjected to correction and fusion by the spinal deformity correction and fusion system.

Abstract: Medical device capable of properly measuring a center of gravity and capable of preventing overturning of a surgical operation table is provided without performing a significant design change. Medical device S, which includes a plurality of leg portions 20 that lift up a main body 2 from a floor surface and support the main body 2, includes load detection devices 55 that are provided between the main body 2 and the respective leg portions 20, and detect loads in a vertical direction received by the leg portions 20 from the floor surface.

Abstract: A surgical operation table capable of operating a table with a large slide width without a slide mechanism interfering with other members in a slide operation of the table is provided. A surgical operation table S including a table 10 movable in a horizontal direction to a base 2 includes a slide mechanism 20 that moves the table 10 in the horizontal direction, and the slide mechanism 20 includes a rack 21a extending in a longitudinal direction of the table 10, a driving gear 26, a driven gear 27 and an idler gear 28 that are meshed with the rack 21a and rotate integrally, and an actuator 23 that supplies a rotational driving force to at least one of the gears 26 to 28.

Abstract: To provide a bone fixation device able to firmly fix bone elements. A bone fixation device, comprising: a base section having a first space that holds a rod; a hook formed with a second space in which a bone element is accommodated together with a art of the base section; and a sandwiching part that is installed to the base section and that sandwiches the bone element which has been accommodated in the second space together with a pail of the hook, wherein the sandwiching part is shiftable allowing attachment to the bone element.

Abstract: A spinal deformity correction and fusion surgery supporting device is capable of simplifying the operative procedures of a spinal deformity correction and fusion surgery by an operator to reduce the operative time and lessen the burden on the patient and achieving a more effective correction rate by the spinal deformity correction and fusion surgery. In this supporting device, the waist and the vicinity thereof are pressed from both sides in the left-right direction by a pair of waist pressing bodies, and the chest and the vicinity thereof are pressed from both sides in the left-right direction by a pair of chest pressing body to establish a trunk balance. In this state, the pair of chest pressing bodies and the pair of waist pressing bodies are moved away from each other to apply a tensile load to spinal deformity and a state in which the spinal deformity is corrected so as to approach a correction rate by the spinal deformity correction and fusion surgery can be maintained.
