Description

Technical Field

[0001] The utility model relates to the technical field of orthopedics, in particular to an auxiliary device for disassembling a leg plate. Background Art

[0002] After surgical treatment of leg fracture, plaster is usually needed for fixation. In clinical practice, plaster bandage is used for plaster. Plaster bandage is made of gauze soaked in quicklime water. When plaster is applied, a certain amount of plaster bandage is repeatedly folded to a certain thickness according to the size of the part, then soaked in water, and quickly covered to the fixed part (the fixed part should be padded with cotton and gauze in advance). After the plaster becomes hard, a leg board will be formed, and finally it can be fixed to the functional position with an ordinary bandage.

[0003] At present, when removing the existing plaster leg board, the patient needs to place the leg flat on a stool, and then the doctor will cut and pry open the plaster. However, the leg is very likely to move during the cutting process, which makes it inconvenient to cut. In addition, since the heights and body shapes of patients with fractures are different, and the height of the stool is the same, it is inconvenient to raise the fractured leg. In addition, the gap is small after the plaster leg board is cut, which is not convenient for the doctor to pry open the plaster board. For this reason, we propose an auxiliary device for leg board removal. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an auxiliary device for disassembling a leg board, which solves the problems raised in the above-mentioned background technology.

By opening a U-shaped groove on the top of the placement block 10, it is convenient for the patient to place the fractured leg and can effectively limit it to avoid the movement of the leg when removing the plaster leg board. The bottom of the base plate 1 is provided with a universal wheel, and the universal wheel is provided with a brake to facilitate the movement of the device. Through the cooperation of the installation box 2, the driving screw 3, the driven bevel gear 4, the rotating rod 5, the transmission bevel gear 6, the slider 7, the support column 8, the support plate 9 and the placement block 10, when in use, the patient can place the patient in the groove opened above the placement block 10, which is convenient for fixing the leg during the disassembly process to avoid the movement of the leg during cutting. After the fractured leg is placed, the doctor can rotate the rotating rod 5 and the transmission bevel gear 6 to drive the driving screw 3 to rotate, which can drive the slider 7 and the support column 8 to rise through the thread. Then the doctor can move the patient's leg to a certain height, which is convenient for the disassembly of the plaster leg board.

[0021] A mounting groove 11 is provided inside the support plate 9, and a bidirectional screw rod 12 is rotatably installed inside the mounting groove 11. Two slide plates 13 are installed on the outer side of the bidirectional screw rod 12 by threads, and two connecting rods 14 are fixedly installed on the outer sides of the two slide plates 13. One end of the connecting rod 14 extends to the outer side of the support plate 9 and a vertical rod 15 is installed.

A guide rod is fixedly installed on one side of the top of the hook plate 18, and the guide rod passes through the interior of the beam frame 16 and is movably connected to it. The main function of the guide rod is to improve the stability of the hook plate 18 when it is opened after being inserted into the gypsum leg board.

[0022] In summary, when using the auxiliary device for leg board removal, first we rotate the handle turntable 19 to drive the bidirectional screw 12 to rotate, so that the two slides 13 can move to both sides, and the connecting rod 14, the vertical rod 15, the beam frame 16, the screw 17 and the hook plate 18 can move to both sides. Then the patient places the leg with the plaster push plate fracture into the groove above the placement block 10, and the doctor can rotate the rocker 20 and the rotating rod 5 and the transmission bevel gear 6, and the transmission bevel gear 6 is engaged with the driven bevel gear 4 to drive the driving The screw rod 3 rotates to make the support column 8 rise through the thread, and the doctor can lift the patient's leg to a height that is convenient for operation. The doctor then cuts the plaster leg board. After cutting, the doctor rotates the reverse handle turntable 19 to move the two hook plates 18 to the top of the cut plaster leg board, and then rotates the screw rod 17 to insert the hook plate 18 into the cut gap. Finally, the doctor rotates the handle turntable 19 to move the vertical rod 15, the beam frame 16, the screw 17 and the hook plate 18 to both sides to disassemble the plaster push plate. It is convenient and quick to use.
