[0002] Plaster casts are a common conservative treatment for fractures and have multiple functions and effects. First, plaster can effectively fix the fracture site, maintain the stability of the fracture ends, reduce the risk of fracture displacement, and thus promote fracture healing. Secondly, plaster fixation can relieve local pain, because maintaining the stability of the fracture site helps reduce pain caused by activities. In addition, plaster can also protect the injured part and prevent it from being impacted by external forces again. It is also conducive to carrying and raising the limbs and helps reduce swelling.
[0003] In the prior art, when bones heal or displacement is found during bone healing, medical plaster needs to be removed. Generally, plaster shears or plaster saws are used for removal. Plaster shears are relatively sharp and require high operating skills of the operator when used. For thicker or harder plaster, an electric plaster saw is needed for cutting. The operator needs to support the patient's leg with one hand and operate the plaster saw with the other hand. After cutting a circle of the plaster on the patient's leg, the plaster is stretched along the incision using a plaster stretcher. The electric plaster saw generates a lot of noise when used.

[0030] By using the first placement rack 1 and the second placement rack 2 in cooperation, the first placement rack 1 and the second placement rack 2 can be installed on the bed, and the initial state of the first placement rack 1, the fixed rack 4, the sliding plate 7, the first connecting plate 11 and the second abutment block 12 is as follows: Figure 3The first support frame 10 is provided with a plurality of support members 14, 16 and 17, and the support members 14 are provided with a plurality of support members 14. The support members 14 are provided with a plurality of support members 16 and 17, and the support members 14 are provided with a plurality of support members 16. The support members 14 are provided with a plurality of support members 16 and 17, and the support members 14 are provided with a plurality of support members 16. The first connecting plate 11 is in contact with the outer wall of the plaster wrapped around the patient's leg, and the first connecting plate 11 is in contact with the outer wall of the plaster wrapped around the patient's leg. The first connecting plate 11 is in contact with the outer wall of the plaster wrapped around the patient's leg, and the first connecting plate 11 is in a wavy structure, has a certain elasticity, and can fully contact the plaster of the patient's leg to abut and limit it. When the plaster of the patient's leg is removed, the patient's leg can be fixed. When the plaster of the patient's leg is cut using the plaster saw 5, the patient's legs will not shake due to tension, which improves the patient's stability during the cutting of the plaster of the affected leg and reduces the difficulty of removing the plaster. The guide component can guide the plaster saw 5 when using the plaster saw 5, so that the plaster saw 5 moves along a specific trajectory to cut the plaster of the patient's leg. The cutting trajectory cooperates with the expansion component, and the expansion component can expand the cut plaster along the cutting trajectory, further speeding up the cutting process, which is beneficial to relieving the patient's psychological tension.
[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8As shown, the guide assembly includes two first mounting frames 15 respectively connected to one side of a pair of fixed plates 3, one side of each first mounting frame 15 is fixedly connected to a pair of limiting plates 16, the limiting plates 16 are elastic structures, and a plurality of weakened grooves are provided on the elastic structure, one end of the pair of limiting plates 16 is fixedly connected to the same first guide plate 19, one side of the first guide plate 19 is fixedly connected to the second guide plate 20, and the first guide plate 19 and the second guide plate 20 are both provided with first through holes 21, one side of the first mounting frame 15 is fixedly connected to a pair of guide rods 17, one side of the first guide plate 19 is fixedly connected to a pair of telescopic rods 18, and the telescopic rods 18 are slidably connected to the guide rods 17, and the gypsum saw 5 slides in the space formed by the first guide plates 19 and the second guide plates 20, and one end of the first guide plates 19 and the second guide plates 20 are both provided with rectangular chamfers.
[0032] The guide assembly is used to guide and limit the plaster saw 5. During the process of cutting the plaster of the patient's affected leg, the plaster saw 5 slides in the space enclosed by the first guide plate 19 and the second guide plate 20. The first guide plate 19 and the second guide plate 20 are both provided with a first through hole 21, which will not hinder the operator's operating line of sight. One end of the first guide plate 19 and the second guide plate 20 are both provided with a rectangular chamfer, which is convenient for the operator to slide and install the plaster saw 5 with the first guide plate 19 and the second guide plate 20. When the plaster saw 5 is used to cut the plaster of the patient's affected leg, after the plaster saw 5 is installed, the operator holds the gripping part of the plaster saw 5, and at this time, the cutting blade of the plaster saw 5 is in contact with the patient's affected leg. The operator can move the plaster saw 5 toward the patient's affected leg, and synchronously drive the first guide plate 19 and the second guide plate 20 to move toward the patient's affected leg. The limit plate 16 is an elastic structure and a plurality of weakened grooves are provided on the elastic structure, so that when the first guide plate 19 and the second guide plate 20 move, the limit plate 16 is pulled to elastically deform, and at the same time, the telescopic rod 18 connected to the first guide plate 19 slides on the guide rod 17, and the guide rod 17 is provided to effectively limit the telescopic rod 18, so as to avoid the first guide plate 19 and the second guide plate 20 from being driven by the gravity of the plaster saw 5 after the plaster saw 5 is installed with the first guide plate 19 and the second guide plate 20. The downward displacement of the first guide plate 19 and the second guide plate 20 improves the stability of the first guide plate 19 and the second guide plate 20 when in use. The shapes of the first guide plate 19 and the second guide plate 20 fit the shapes of the patient's leg to the foot, so that when the plaster saw 5 is used to cut the plaster of the patient's leg, the plaster of the patient's leg can be cut without dead angles, thereby improving the stability of plaster removal. When removing the plaster, there is no need for the operator to hold the patient's leg, thereby improving the stability of the operation. After the cutting of one side of the plaster of the patient's leg is completed, the plaster saw 5 can be slid and removed along the first guide plate 19 and the second guide plate 20, and switched to the other side of the patient's leg, and the above operation is repeated to cut the plaster on the other side of the patient's leg. The entire cutting process is seamless. The patient's legs need not be rotated or moved, which improves the patient's comfort during the plaster removal process. After the plaster cutting is completed, the plaster saw 5 is slid and removed from the first guide plate 19 and the second guide plate 20, and the first guide plate 19 and the second guide plate 20 are driven to return to their original positions under the elastic force of the limit plate 16 for easy use next time. At this time, the operator can use the expansion component to expand the plaster cutting seam. After the expansion is completed, the first abutment block 10 and the sliding plate 7 can be rotated in the opposite direction so that the sliding plate 7, the first abutment block 10, the first connecting plate 11 and the second abutment block 12 are restored to their original positions, the plaster is separated, and then the gauze in the plaster is cut with scissors or other tools, and finally the entire plaster is removed.
[0033] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7As shown, the splay assembly includes two pairs of mounting plates 22 respectively fixedly connected to one side of a pair of fixing plates 3, each pair of mounting plates 22 is fixedly connected with a second mounting frame 23, the second mounting frame 23 is provided with a third through hole 33, one side of the second mounting frame 23 is fixedly connected with a plurality of first positioning plates 24, the bottom of the first positioning plate 24 is fixedly connected with a first splay plate 26, one side of the second mounting frame 23 is fixedly connected with a plurality of second positioning plates 25, the top of the second positioning plate 25 is fixedly connected with a second splay plate 27, one end of the first splay plate 26 abuts with one end of the second splay plate 27, one end of the first positioning plate 24 and one end of the second positioning plate 25 are both inclined toward the middle position of the first placement rack 1, one end of the first splay plate 26 and one end of the second splay plate 27 abuts with each other to form a V-shaped structure, the first positioning plate 24 is inclined toward one end of the first splay plate 26, and the second positioning plate 2 5 is inclined toward one end of the second opening plate 27, the first positioning plate 24 and the second positioning plate 25 are both elastic structures, and a plurality of weakened grooves are provided on the elastic structure, and an inclined groove 32 is provided on one side of the first opening plate 26 and the second opening plate 27, and a pair of second connecting plates 29 are fixedly connected to one side of the second mounting frame 23, and an opening rod 28 is fixedly connected to one end of the second connecting plate 29, and a plurality of anti-slip grooves are provided on both ends of the opening rod 28, and a second through hole 30 is provided on the opening rod 28, and the outer wall of the opening rod 28 abuts against the inner wall of one end of the first opening plate 26 and the inner wall of one end of the second opening plate 27, and one end of the first opening plate 26 and the second opening plate 27 are both arc-shaped structures, and the inner wall of the arc-shaped structure is adapted to the outer wall of the opening rod 28, and a stopper 31 is fixedly connected to one side of the first opening plate 26 and one side of the second opening plate 27, and the stopper 31 abuts against the outer wall of the opening rod 28.
[0034] Through the setting of the expansion assembly, the first expansion plate 26 and the second expansion plate 27 are both inclined toward the middle position of the first placement frame 1, and one end of the first expansion plate 26 and the second expansion plate 27 are abutted to form a V-shaped structure. The first expansion plate 26 and the second expansion plate 27 are respectively connected to the second mounting frame 23 through the first positioning plate 24 and the second positioning plate 25. The second mounting frame 23 is provided with a third through hole 33, which will not affect the use of the cutting head of the gypsum saw 5. The first positioning plate 24 and the second positioning plate 25 are both elastic structures, and a plurality of weakened grooves are provided on the elastic structure. The first positioning plate 24 and the second positioning plate 25 are respectively inclined toward one end of the first expansion plate 26 and one end of the second expansion plate 27. In the initial state, one end of the V-shaped structure of the first spreading plate 26 and the second spreading plate 27 abuts against the outer wall of the plaster of the patient's affected leg. When the operator uses the plaster saw 5 to cut the plaster of the patient's affected leg, one end of the V-shaped structure of the first spreading plate 26 and the second spreading plate 27 is inserted into the cutting seam under the action of the elastic force of the first positioning plate 24 and the second positioning plate 25. Multiple groups of first spreading plates 26 and second spreading plates 27 are inserted into the cutting seam in sequence. After the plaster on both sides of the patient's affected leg is cut, the operator can pull the two spreading rods 28 to move the spreading rods 28 toward the patient's affected leg. During the movement, the first spreading plate 26 and the second spreading plate 27 can be driven to move in opposite directions. The distribution trajectories of the multiple sets of second spreading plates 27 and spreading rods 28 fit the shape of the patient's affected leg to foot, and the entire cutting seam can be spread open at one time, further improving the efficiency of plaster removal. During the removal process, a second through hole 30 is provided on the spreading rod 28, which will not hinder the use of the cutting head of the plaster saw 5. When the plaster saw 5 is in use, the first spreading plate 26 and the second spreading plate 27 can be spread apart. When the plaster saw 5 moves along the first guide plate 19 and the second guide plate 20, the oblique grooves 32 provided on one side of the first spreading plate 26 and the second spreading plate 27 make it easier for the cutting head of the plaster saw 5 to be inserted into the middle position of the first spreading plate 26 and the second spreading plate 27, so that the first spreading plate 26 and the second spreading plate 27 can be opened. The plate 27 will not hinder the use of the gypsum saw 5. When the cutting head of the gypsum saw 5 leaves the first expansion plate 26 and the second expansion plate 27, the first positioning plate 24 and the second positioning plate 25 drive one end of the V-shaped structure of the first expansion plate 26 and the second expansion plate 27 to be inserted into the cutting seam under the elastic force of the first positioning plate 24 and the second positioning plate 25 respectively. Both ends of the expansion rod 28 are provided with multiple anti-slip grooves for the convenience of the operator. The set block 31 cooperates with the arc structure on one side of the first expansion plate 26 and the second expansion plate 27, so that the expansion rod 28 remains stable when not in use. The expansion rod 28 is connected to the second mounting frame 23 through a pair of second connecting plates 29. The second connecting plate 29 has an elastic structure to facilitate the expansion rod 28 to return to its original position.
[0035] The working principle of the technical solution provided by the present invention is as follows: the first placement rack 1 and the second placement rack 2 can be installed on the bed, and the initial state of the first placement rack 1, the fixed rack 4, the sliding plate 7, the first connecting plate 11 and the second abutment block 12 is as follows: Figure 3 As shown, the fixing frame 4 is clamped with the thigh of the affected leg which is not in the plaster, and the patient's calf, that is, the ankle, is placed on the second placing frame 2. The first placing frame 1 and the second placing frame 2 support the patient's affected leg. After the patient places the affected leg, the operator can pull the first abutment block 10 to drive the sliding plate 7 to move along the arc surface of the fixing frame 4 until the clamping block 9 is clamped with the second arc plate 14. At this time, the fixing frame 4 and a pair of sliding plates 7 are matched to wrap the patient's thigh position. The first connecting plate 11 is rotated into place with the sliding plate 7 to abut against the outer wall of the plaster wrapped around the patient's affected leg, and the second abutment block 12 is abutted against the outer wall of the plaster included outside the patient's affected leg and calf.
[0036] During the process of cutting the plaster of the patient's affected leg, the plaster saw 5 slides in the space enclosed by the first guide plate 19 and the second guide plate 20. The first guide plate 19 and the second guide plate 20 are both provided with a first through hole 21, which will not hinder the operator's operating line of sight. When using the plaster saw 5 to cut the plaster of the patient's affected leg, after the plaster saw 5 is installed, the operator holds the gripping part of the plaster saw 5. At this time, the cutting blade of the plaster saw 5 is at a certain distance from the plaster of the patient's affected leg. The operator can move the plaster saw 5 toward the patient's affected leg, and synchronously drive the first guide plate 19 and the second guide plate 20 to move toward the patient's affected leg. At the same time, the telescopic rod 18 connected to the first guide plate 19 is moved in the guide The first guide plate 19 and the second guide plate 20 are shaped to fit the shape of the patient's affected leg to the foot, so that when the plaster saw 5 is used to cut the plaster of the patient's affected leg, the plaster of the patient's affected leg can be cut without dead angles. After the plaster on one side of the patient's affected leg is cut, the plaster saw 5 can be slid and removed along the first guide plate 19 and the second guide plate 20, and switched to the other side of the patient's affected leg, and the above operation is repeated to cut the plaster on the other side of the patient's affected leg. After the plaster cutting is completed, the plaster saw 5 is slid and removed from the first guide plate 19 and the second guide plate 20, and the first guide plate 19 and the second guide plate 20 are driven to return to their original positions under the elastic force of the limiting plate 16 for easy use next time.
[0037] At this time, the operator can use the expansion assembly to expand the plaster cutting seam. One end of the V-shaped structure of the first expansion plate 26 and the second expansion plate 27 is inserted into the cutting seam under the elastic force of the first positioning plate 24 and the second positioning plate 25. Multiple groups of first expansion plates 26 and second expansion plates 27 are inserted into the cutting seam in sequence. After the plaster on both sides of the patient's affected leg is cut, the operator can pull the two expansion rods 28 to move the expansion rods 28 toward the patient's affected leg. During the movement, The first expansion plate 26 and the second expansion plate 27 are driven to move in opposite directions. The distribution trajectories of the multiple sets of second expansion plates 27 and expansion rods 28 fit the shape of the patient's affected leg to the foot, and the entire incision seam can be expanded at one time. After the expansion process is completed, the first abutment block 10 and the sliding plate 7 can be rotated in the opposite direction so that the sliding plate 7, the first abutment block 10, the first connecting plate 11 and the second abutment block 12 are restored to their original positions, the plaster is separated, and then scissors and other tools are used to cut the gauze in the plaster, and finally the entire plaster is removed.
