[0017] Beneficial Effects

[0018] The present invention has the following beneficial effects:

[0019] The rehabilitation shaped plaster cutting device for orthopedic treatment realizes intelligent switching between cutting and cracking functions through the cooperation of the driving component with the first and second gear rings. When the cutting motor is stationary, the drive mode conversion can be completed only by the aggregation and expansion of the spring rod, without the need for an additional power source, which significantly simplifies the operation process. In the cutting stage, the ring saw blade is driven by the first gear ring to accurately open the slit, and in the cracking stage, the tip of the crack is periodically driven by the second gear ring to expand, with a high degree of functional integration.

[0020] The device for cutting rehabilitation shaped plaster for orthopedic treatment uses a convex block, telescopic column and inverted cone linkage design in the cracking component. When the second gear ring rotates, the inclined surface of the convex block squeezes the telescopic column step by step, and cooperates with the reset spring to form a pulse cracking action. The periodic impact force can effectively expand the cutting seam, avoid the risk of plaster fragmentation caused by a one-time strong opening, and reduce the pressure on the patient's skin.

[0021] During the cutting process, the circular cutting saw always fits the plaster surface and the overall structure of the device is stable, which reduces the risk of accidental damage to the patient's skin caused by the cutting tool. At the same time, when the splitting component is splitting the cutting seam, it can effectively open the cutting seam without damaging the patient's skin through a specific structural design, making it easier to remove the plaster later.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] Specifically, the driving assembly includes a shaft seat 11, a driving shaft 12, a transmission shaft 13, and a driving gear set 18. The shaft seat 11 is symmetrically sleeved on the outer side of the driving shaft 12, and teeth are provided on the outer side of the driving shaft 12. The transmission shaft 13 penetrates the driving shaft 12 and is movably arranged. The shaft seat 11 is fixedly installed on the inner side of the square hole 27, and the driving gear set 18 is equidistantly arranged on the outer side of the transmission shaft 13, wherein the driving gear set 18 is composed of two groups of annular teeth, wherein one group of teeth is meshed with the gear ring 2 16, and the driving shaft 12 is meshed with the gear ring 1 15. One end of the driving shaft 12 is provided with a tooth groove which is connected to the driving gear set 18 and is close to the driving shaft 12.

[0039] A clamping hole 30 is provided on the surface of a group of spring rods 6, a clamping bead 32 is movably installed inside the clamping hole 30, a push rod 14 is fixedly installed on the outer side of the clamping bead 32, and the other end of the push rod 14 is used in conjunction with the driving component. The spring rod 6 is also connected through the torsion spring seat 29.

[0040] In the present embodiment, a driving component is provided to drive the gear ring 15 and the gear ring 2 16, wherein the driving component can switch the state to realize the separate driving of the gear ring 15 and the gear ring 2 16, wherein the driving state of the gear ring 15 and the gear ring 2 16 are switched when the cutting motor 4 is in a stationary state, wherein the driving tooth group 18 on the outer side of the transmission shaft 13 and the gear ring 2 16 are initially in a separated state, wherein one group of teeth is meshed with the tooth groove at one end of the driving shaft 12, so that the cutting motor 4 will drive the transmission shaft 13 to drive the driving shaft 12 when it rotates, and since the teeth on the outer side of the driving shaft 12 are meshed with the gear ring 1 15 meshes, so the gear ring 15 rotates along the inner wall of the installation groove 19, thereby driving the circular cutting saw 8 to cut the plaster. It should be noted that the inner diameter of the circular cutting saw 8 matches the outer diameter of the plaster. Since the circular cutting saw 8 is arranged at the center of the gear ring 15, the outer side of the circular cutting saw 8 can be connected to the inner wall of the plaster hole 7 through a spring, thereby ensuring that the circular cutting saw 8 is always in contact with the plaster, and the circular cutting saw 8 is arranged in a circular shape by piecing together a number of annular saw blades and installed through the installation groove in the gear ring 15. Therefore, the gear ring 15 drives the circular cutting saw 8 to rotate under the drive of the driving shaft 12 to perform circular cutting on the plaster.

[0041] The state switching of the driving component is achieved by controlling the expansion and aggregation states of the spring rod 6, and the switching states are all achieved when the cutting motor 4 is in a stationary state. When the spring rod 6 is in an aggregated state, since the push rod 14 serves to connect the spring rod 6 and the transmission shaft 13, the spring rod 6 will pull the push rod 14 to make the driving tooth group 18 on the outside of the transmission shaft 13 engage with the driving shaft 12, thereby driving the gear ring 1 15. At this time, the gear ring 2 16 is in a stationary state. When the spring rod 6 is in an expanded state, the spring rod 6 will push the push rod 14 to separate the driving tooth group 18 on the outside of the transmission shaft 13 from the driving shaft 12, and another group of teeth in the driving tooth group 18 engage with the gear ring 2 16, thereby driving the gear ring 2 16. At this time, the gear ring 1 15 is in a stationary state.

[0042] Specifically, the cracking assembly includes a top cracking tube 9, a mounting hole 22, a reset spring column 26, a telescopic column 21, and an inverted cone 23. The top cracking tube 9 is fixedly mounted on the inner wall of the mounting hole 28, the mounting hole 22 is opened through one end of the top cracking tube 9, the reset spring column 26 is arranged on the inner side wall of the mounting hole 22, the telescopic column 21 is movably mounted on the inner wall of the mounting hole 22, the inverted cone 23 is fixedly mounted on the inner end of the telescopic column 21, and one end of the telescopic column 21 is in contact with the gear ring 16.

[0043] In the present embodiment, a cracking assembly is provided to crack the cut seam of the shaped gypsum after cutting, so that the cut part is cracked, which is convenient for the later disassembly of the gypsum. The top cracking tube 9 is used to install the components in the cracking assembly. The tooth ring 16 rotates under the drive of the driving tooth group 18 to drive the protrusion 20 to rotate. Since the telescopic column 21 fits the inner side of the protrusion 20, the telescopic column 21 will be gradually squeezed. As the telescopic column 21 moves, the reset spring column 26 is squeezed and stores a certain elastic potential energy. The inverted cone 23 at one end of the telescopic column 21 squeezes the inclined groove on the inner side of the support tip 25, thereby squeezing the support tip 25 to expand it. In order to open the cutting seam, it is necessary to move the sliding seat 2 after cutting to drive the cylindrical cutting frame 10 to move as a whole, move the cracking assembly to the cutting seam, and make the tip of the support tip 25 The end is inserted into the cutting seam, and then the spring rod 6 is expanded and flipped outward to drive the push rod 14 to squeeze the transmission shaft 13, so that it pushes the cutting motor 4 to slide backward along the motor seat 17, and one group of teeth is separated from the tooth groove at one end of the driving shaft 12, and the other group of teeth in the driving tooth group 18 is meshed with the teeth on the gear ring 2 16. At this time, the cutting motor 4 is driven at a low speed, and its control signal gives the cutting motor 4 a pulse signal with an external control device. The pulse signal is a prior art and can be directly used with the cutting motor 4. Without disclosing its specific structure, the pulse signal mainly comes from the pulse generating device, which is converted into an electrical signal to drive the cutting motor 4, so that it deflects at a certain angle, thereby realizing the low-speed driving of the gear ring 2 16, and then realizing the driving of the cracking component to complete the cracking of the cutting seam.

[0044] Specifically, a protrusion is provided on the outer side of the telescopic column 21, and the protrusion is movably connected to the guide column in the return spring column 26. The initial state of the spring on the outer side of the guide column is the original length state, and the other end of the telescopic column 21 is provided with a rounded corner.

[0045] In the present embodiment, a protrusion is provided on the outer side of the telescopic column 21 for use in conjunction with the reset spring column 26 to achieve the resetting of the telescopic column 21, wherein the protrusion squeezes the spring so that it stores a certain elastic potential energy. When the squeezing force on the telescopic column 21 disappears, the telescopic column 21 is reset under the action of the elastic potential energy of the spring on the reset spring column 26.

[0046] Specifically, the crack support assembly also includes a support shaft 24 and a support tip 25. The support shaft 24 is equidistantly arranged on the inner wall of the mounting hole 22 in a circumferential manner. The support tip 25 is movably installed on the outer side of the support shaft 24. An inclined surface is provided on the inner side of the support tip 25, and the inverted cone 23 is used in conjunction with the inclined surface.

[0047] In this embodiment, a support shaft 24 is provided for installing the support shaft 24, wherein the support shaft 24 is triangularly distributed. When the inverted cone 23 squeezes the support shaft 24, the inclined groove on the inner side of the support shaft 24 gradually narrows, thereby causing the support tip 25 to expand outward, thereby completing the cracking of the gypsum cut.

[0048] Specifically, the inner side of the second gear ring 16 is provided with convex blocks 20 at equal intervals in a circumference, the inner side of the convex block 20 is arranged in close contact with the telescopic column 21, and the convex block 20 is provided with a gradually increasing inclined surface.

[0049] In this embodiment, the protrusion 20 is provided to squeeze the telescopic column 21. The telescopic column 21 is squeezed step by step under the action of the inclined surface of the protrusion 20, and the support tip 25 is widened. When the protrusion 20 rotates, the telescopic column 21 is squeezed periodically, so that the support tip 25 also expands periodically, thereby completing the impact and cracking of the crack.

[0050] Specifically, a second clamping hole 31 is opened at one end of the transmission shaft 13, the driving assembly is located above the torsion spring seat 29, and the initial state of one end of the push rod 14 and the first clamping hole 30 is a separation state.

[0051] In this embodiment, a second latch hole 31 is provided at one end of the transmission shaft 13 to engage with a latch bead 32 at one end of the push rod 14 so that the push rod 14 can rotate along the second latch hole 31. When the spring rod 6 flips upward and expands, the push rod 14 pushes the transmission shaft 13 to move, thereby switching the drive assembly.

[0052] Specifically, a limiting groove is provided on the surface of the motor seat 17, a spring column is arranged inside the limiting groove, a slider is movably installed inside the limiting groove, and the slider is fixedly connected to the cutting motor 4, wherein the slider is sleeved on the spring column.

[0053] In this embodiment, a limiting groove, a slider and a spring column are set at the bottom of the motor seat 17 to limit and pull the cutting motor 4. When the driving source of the cutting motor 4 comes from the spring rod 6 that flips and expands upward, the spring rod 6 pushes the top rod 14 so that the transmission shaft 13 pushes the cutting motor 4 to move backward, thereby realizing the switching of the driving gear group 18.

[0054] When in use, the plaster to be cut is passed through the plaster hole 7 by the plaster cutting device, and then the sliding holder 2 is driven to move along the guide frame 1 by pushing the cylindrical cutting frame 10. When it reaches the preset cutting position, the sliding holder 2 is locked by the locking bolt. Then the spring rod 6 is pulled down to make it gather toward the center of the cylindrical cutting frame 10 to fix the plaster. Then the gear ring 15 is driven by starting the cutting motor 4 to cut the plaster. When the plaster cutting is completed, the driving of the cutting motor 4 is stopped. When it stops completely, the spring rod 6 is flipped to separate it from the plaster. Then the locking of the sliding holder 2 is released. The cylindrical cutting frame 10 is pushed again to insert the cracking component into the cutting seam. Then the sliding holder 2 is positioned. The cutting motor 4 is driven again to rotate at a low speed to drive the cracking component to crack the plaster cutting seam.
