The utility model is designed to meet the requirements of the optional positions of supporting devices needed to be adjusted for supporting hands which are burnt, are needed to be skin grafted, and are needed to do the traumatic operations. The utility model is composed of a base whose horizontal angulation can be adjusted, a forearm supporter which can fit different elevation angles, a supporting rod with a ball articulation, and a movable support which can adjust distances between fingers. The movable supports can be turned, and can be positioned. The utility model can be used for the operations and the skin grafting of fingers, finger webs, and wrists; the utility model can also be turned over; the utility model also is a guiding tool which can be used for the recovery of functional movement exercises of the hands after the operations.

Description

Multipurpose hand supporter

This utility model belongs to medical apparatus and instruments.

People's hand is burnt or is subjected to is its function of recovery after other wound, needs to do very careful operation, when adapting to all places of performing the operation required as if no fixing device, then need the assistant to help and show various angles, what have needs the long period, and this is an onerous toil, and is difficult for stable.Learn that through investigation some simple supports are arranged abroad, as the back of performing the operation there is simple surgical stent but function is few for avoiding the hanger bracket of edema usefulness, can not satisfies the needs of operation in the use.

The purpose of this utility model is the needs for the hand operation of satisfying burn or other wound, as hands being fixed on the desired position in cutting scab and skin grafting, can point, refer to operate on web and the wrist easily, and this instrumentation being convenient.Operation back this hand support under other people help can also play the guiding function of simple motion exercise.

It is characterized in that by the as above designed multifunctional hand brace of thinking, it by the hinged pole of the brace base that needs adjustable Plane Angle for operation, the preceding arm support that can adapt to the different elevations angle needs, dribbling, to have distance between the adjustable finger of five covers turning and the localized travel(l)ing rest of energy is formed.

Need the brace base portion of adjustable Plane Angle to be made up of base, connection bent plate and lock screw for operation in this utility model, bent plate and base connect with bearing pin, and lock screw is with the circular arc slotted hole place locking of bent plate under base.During use bent plate and operating-table or operation table are linked, can change the angle on the plane as required, easy to operate to guarantee.Connect with hinge and spring between its preceding arm support that adapts to different elevations angle needs and the base, lift naturally, have in the upper end of support and tighten the belt that wrist is used at the effect lower carriage of spring.

Distance is turning and can localized travel(l)ing rest partly be can transfer five fingerstall of degree of tightness by the band set screw between the adjustable finger of this multifunctional hand brace, the hinged coupling bar of dribbling, big arm; forearm; big arm tie-plate with threaded hole; the forearm tie-plate of band unthreaded hole; the adjusting leading screw of band handle and pole upper hinge are constituted; wherein coupling bar and big arm; big arm and forearm; big arm and big arm tie-plate; all be hinged with bearing pin between forearm and the forearm tie-plate; the forearm tie-plate is to lean on step and little axle sleeve on the lead screw shaft to be associated in the pole upper hinge; the rotation relation between them is located with spring catch; the spring catch of this location usefulness is contained on the pole upper hinge has corresponding three or more than three locating hole on the forearm tie-plate.

The travel(l)ing rest part and the hinged pole of dribbling of the adjustable span of this multifunctional hand brace are used thread connection.The pole of ball-joint can be done the adjusting adaptation of various angles according to the needs of the length of suffering from limb and operation, mixes up the gland locking of back with ball pivot, forms a fixed position.

Five fingerstall of this multifunctional hand brace are to make with flexible plastic or rubber.

When the needs of patients of burn or other wound is performed the operation, on operating-table or operation table, install this multifunctional hand brace, patient's forearm partly is placed on the preceding arm support, wrist is tightened with belt, five fingers insert corresponding fingerstall, and tighten with the adjustment screw, according to open degree between the length of suffering from limb and finger, can adjust the angle of leading screw and ball-joint.If be rotated counterclockwise the adjusting leading screw, then big arm tie-plate to be released to the far-end of leading screw, big and small arms opens gradually, and the distance between finger also strengthens, instead then against it.According to can the overturn relative position of the back of the hand and the palm of the hand of the needs of operation, extract spring catch earlier the travel(l)ing rest part is rotated on leading screw, find the position of suitable locating hole, spring catch is inserted dead.According to operation technique conveniently adjust level angle, with the locking of the lock screw under the base, so just can obtain the optimum position of operation needs after mixing up, obtain a stable support, need not assistant's support.

This brace also can be used as the guiding tool of motion exercise after the operation.By other people rotating threaded shaft, be screwed into counter-rotating again behind the summit, just can help patient to point and open the slow motion of stretching.Extract spring catch rotary moveable holder part slowly, bootable patient makes the flip-flop movement of wrist.

Use the technical program can embody following superiority: 1. the position of each several part, angle be adjustable, can both be fastening after the adjustment, can adapt to the different size of suffering from limb, can obtain the optimum position of stable operation needs, need not assistant's support; 2. cut when making skin graft after the crust, can suitably adjust as required, can keep the position of skin graft to avoid slippage; 3. all places is easy to adjust, is convenient to the operation wrapping; 4. can also do the guiding of motion for suffering from the limb postoperative.
