Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a postoperative medical rehabilitation device, and may also relate to a neurosurgical postoperative medical rehabilitation device. Background Technology

[0002] In neurosurgical clinical practice, patients post-operatively diagnosed with traumatic brain injury, cerebral hemorrhage, cerebral aneurysm, or brain tumor often experience varying degrees of neurological functional impairment. This manifests as limb movement disorders (such as upper limb weakness and lower limb instability), balance dysfunction (such as a tendency to tilt to one side when standing), abnormal muscle tone (such as limb stiffness or laxity), and decreased limb coordination. The core goal of post-operative rehabilitation for these patients is to gradually restore limb self-control, balance, and daily activities through scientific exercise to stimulate neural pathway reconstruction, thereby reducing the incidence of sequelae. For example, early targeted rehabilitation training can reduce complications such as muscle atrophy and joint contractures; mid-term training can improve the stability of standing and walking; and late-term training helps patients return to basic life activities such as independent eating and dressing, which is crucial for improving the post-operative quality of life. However, once installed, the core functional components of existing medical rehabilitation equipment (such as the height and horizontal spacing of the handrails for support, and the relative position of the pedals for lower limb training) are fixed and cannot be dynamically adjusted according to the patient's specific degree of functional impairment and rehabilitation stage.

[0003] Prior art 1 (application number: 2020216893055, application date: 2020.08.13) discloses a medical rehabilitation exercise device, including: a base plate 1'; a vertical adjustment assembly, which includes: a first screw 4', a first sliding block and a horizontal plate; a horizontal adjustment assembly, which includes: a second screw 8', a second sliding block 9' and an L-shaped hand handle 10'; a limiting assembly; and an exercise structure, which includes: a mounting plate 11', an arc plate 12', a movable seat 13', and a rotating pedal 14'. The above-mentioned solutions are not designed to address the core characteristics of post-neurosurgery patients, such as "weak limb muscle strength, poor balance function, and dynamic changes during the rehabilitation stage." On the one hand, the height and horizontal spacing of the handrails and the relative position of the pedals are all fixed, making it impossible to make personalized adjustments according to the individual needs and rehabilitation stage of the patients. On the other hand, post-operative patients cannot use the devices stably and safely due to the inability to support themselves and the limited range of training. In addition, patients' physical functions are relatively inconvenient during the rehabilitation process, and the above-mentioned devices cannot be used by patients in a convenient way, increasing the assistance pressure on medical staff.

[0004] Prior art 2 (application number: 2017110671383, application date: 2017.11.03) discloses a limb rehabilitation exercise device for rehabilitation department, including a base, a support column is fixedly mounted on the upper right end of the base, a rotating sleeve is rotatably mounted on the top of the support column, the rotating sleeve is fixedly mounted on the top of the support column by fastening bolts, a crossbeam is fixedly mounted on the rotating sleeve, a fixed plate is symmetrically fixedly mounted on the lower surface of the crossbeam, a lead screw is rotatably mounted between the two fixed plates by bearing connection, a handle is fixedly mounted on the left end of the lead screw, a feed block is mounted on the lead screw by threaded connection, a connecting rod is rotatably hinged at the bottom of the feed block by a hinge shaft, a No. 4 spring is fixedly connected to the bottom end of the connecting rod, and a handle is fixedly mounted on the other end of the No. 4 spring. The foot support plate in the above solution has a fixed tilt angle and cannot be adjusted according to the patient's knee joint mobility. For example, patients with flexion contractures need a smaller tilt angle. Safety protection is lacking. The support structure does not have auxiliary stabilizing components designed for patients with poor balance function, such as adjustable handrails and anti-tipping side guards, which poses a risk of tipping during training. It also cannot meet the needs of lumbar rotation training.

[0005] Prior art 3 (application number: 2021104440674, application date: 2021.04.23) discloses a combined sports equipment, which includes a support column, a fixed base plate, a height adjustment mechanism, an anti-twist turntable mechanism, an upper body fixation mechanism, and an extension exercise mechanism; the fixed base plate is welded to the bottom of the support column; the height adjustment mechanism is assembled inside the support column; the anti-twist turntable mechanism is located on the outer side of the lower end of the support column; the upper body fixation mechanism is slidably assembled in the middle of the support column and located directly above the anti-twist turntable mechanism, and the upper body fixation mechanism is connected to the height adjustment mechanism. The above solution lacks a lower limb-specific training module, preventing patients from performing basic muscle strength training such as lower limb flexion and extension, and leg extension through the equipment; it lacks advanced balance training design, only allowing indirect balance training through waist twisting, and cannot provide single-leg standing assistance, small-range center of gravity transfer, or other training functions.

[0006] Prior art 4 (application number: 2023235224962, application date: 2023.12.23) discloses a medical rehabilitation exercise device. A comparison with the accompanying drawings in the instruction manual of this medical rehabilitation exercise device is provided. Figure 1 With reference to the drawings in this application specification Figure 2 The two have completely different structures; for example, the medical rehabilitation exercise equipment in the prior art 4 is a treadmill with a track, while this application is a vertical gantry frame that does not contain any track or electric transmission structure.

[0007] Prior art 5 (application number: 2023217855213, application date: 2023.07.07) discloses a medical rehabilitation exercise device. A comparison with the accompanying drawings of the instruction manual for this medical rehabilitation exercise device is provided. Figure 1 With reference to the drawings in this application specification Figure 2The two have completely different structures; for example, the medical rehabilitation exercise device in the prior art 5 is a rectangular bed set in the horizontal direction, while the present application is an E-shaped frame set in the vertical direction.

[0008] Prior art 6 (application number: 2025104733014, application date: 2025.04.16) discloses a cardiac surgery rehabilitation training device. A comparison with the accompanying drawings of the instruction manual for this cardiac surgery rehabilitation training device is provided. Figure 1 With reference to the drawings in this application specification Figure 2 The two have completely different structures; for example, the prior art 6 is a seat with the length extension direction in the horizontal direction, while this application is an E-shaped frame with the length extension direction in the vertical direction.

[0065] The number of weight blocks 343 is at least two, and each of the at least two weight blocks 343 has a circular first sliding hole 3431, a second sliding hole 3432 and a through hole 3433 along its thickness direction; the first sliding holes 3431 of the at least two weight blocks 343 are sequentially connected to the outer wall of the first sliding rod 3471, the second sliding holes 3432 of the at least two weight blocks 343 are sequentially connected to the outer wall of the second sliding rod 3472; the through holes 3433 of the at least two weight blocks 343 are sequentially connected to the outer wall of the fixed rod 345.

[0066] Along the thickness direction of the base plate 11, the length of the fixing rod 345 is greater than the sum of the thicknesses of at least two load blocks 343; a cylindrical limiting post 3451 is provided at one end of the fixing rod 345 near the upper side plate, and the radius of the limiting post 3451 is greater than the radius of the through hole 3433; the end of the limiting post 3451 near the upper side plate is fixedly connected to the traction rope 341; the Y-shaped intersection of the traction rope 341 is located on the side of the traction through hole away from the load block 343, and the two ends of the traction rope 341 near the horizontal segment of the π are respectively wrapped and fixed to the beginning and end ends of the horizontal segment of the π along its length direction;

[0067] The fixing rod 345 has at least two circular first limiting holes 3452 along the length of the base plate 11. The first limiting holes 3452 pass through the fixing rod 345 along the length of the base plate 11. The at least two first limiting holes 3452 are arranged along the length of the fixing rod 345. Each load block 343 has a second limiting hole 3434 that matches the first limiting hole 3452 along the length of the base plate 11. A circular pin 346 is inserted into the second limiting hole 3434 and the corresponding first limiting hole 3452.

[0068] Specifically, continue to refer to Figures 2-4 As shown, this postoperative medical rehabilitation equipment can also be used for postoperative medical rehabilitation of neurosurgery.

[0069] The aforementioned foot support mechanism 1 includes a base plate 11 and a turntable 12. The base plate 11 is a rectangular metal plate, and the metal material of the base plate 11 helps to enhance the fatigue resistance and support capacity of the base plate 11. The base plate 11 is placed horizontally on the ground. Depending on the specific installation scenario during use, a sponge pad can be added to the side of the base plate 11 closest to the bottom surface; the sponge pad is placed directly between the ground and the base plate 11, and is fixed by the gravity pressing of the base plate 11 and the upper mechanism, thereby enhancing the placement stability of the base plate 11. A turntable 12 is welded to the wide side of the base plate 11 away from the ground. The turntable 12 is generally shaped like a frustum, and includes spherical ball bearings 121, a trumpet-shaped fixing seat 122, and a circular inner turntable 123. The fixing seat 122 forms the outer surface of the frustum, that is, the mother surface of the frustum. The fixed base 122 has an upper opening and a lower opening arranged vertically opposite each other along its axial direction. Both the upper and lower openings are circular, with the upper opening of the fixed base 122 being smaller than its lower opening. The diameter of the upper opening of the fixed base 122 is equal to the diameter of the inner turntable 123, and the upper opening is located on the side opposite to the base plate 11. The lower opening of the fixed base 122 is welded to the base plate 11 with its entire surface overlapping. The inner turntable 123 is placed inside the upper opening of the fixed base 122 and rotates around the inner diameter of the fixed base 122. The inner turntable 123, the fixed base 122, and part of the base plate 11 form a hollow part of a frustum, which is used to load the ball bearings 121. At least three ball bearings 121 are provided; the diameter of the ball bearings 121 is not greater than the radius of the inner turntable 123. Through the ball bearings 121, the inner turntable 123 can be supported along the thickness direction of the base plate 11, and the inner turntable 123 can rotate within the fixed base 122.

[0070] Specifically, continue to refer to Figure 4 As shown, an annular upper track 125 is welded to the side of the inner turntable 123 near the base plate 11. The upper track 125 is parallel to the inner turntable 123, and its maximum outer diameter is smaller than the diameter of the inner turntable 123. Along the thickness direction of the base plate 11, the orthographic projection of the upper track 125 is circular; along the circumferential direction of the upper track 125, any cross-sectional shape is concave; the opening of the upper track 125 faces the groove of the base plate 11. A lower track 126 is welded to the side of the base plate 11 near the inner turntable 123. The lower track 126 has the same structural size as the upper track 125, and its groove opening faces the upper track 125. Along the thickness direction of the base plate 11, the orthographic projections of the upper track 125 and the lower track 126 coincide. The grooves of the upper track 125 and the lower track 126 cooperate to engage the ball bearing 121. The upper rail 125 and the lower rail 126 are used to avoid disorderly collisions between the three balls 121, enhance the durability of the balls 121, extend their service life, and reduce maintenance costs. In this embodiment, three balls 121 are used as an example, and all three balls 121 are engaged between the lower rail 126 and the upper rail 125; the three balls 121 are not a limitation on the number of balls.

[0071] The inner turntable 123 is also made of metal. A foot-shaped groove 124 recessed into the base plate 11 is provided on the side of the inner turntable 123 away from the base plate 11; there are two foot-shaped grooves 124, corresponding to the patient's left and right feet respectively; the patient's left and right feet can be placed in the two foot-shaped grooves 124 respectively, allowing them to stand on the inner turntable 123 and rotate clockwise or counterclockwise. The foot-shaped grooves 124 enhance the stability of the patient's left and right feet on the inner turntable 123 and strengthen the connection between the left and right feet on the inner turntable 123.

[0072] Continue to refer to Figures 2-5 As shown, the seating mechanism 2 includes a rectangular backrest 21, a rectangular seat 22, and a strip-shaped fixing component 23; both the backrest 21 and the seat 22 are arc-shaped structures, and the seat 22 and the fixing component 23 are respectively fixed on opposite sides of the backrest 21 along its thickness direction.

[0073] The back plate 21 is bent into an arc shape along the central axis of the inward turntable 123; the bottom end of the back plate 21 is welded to the outer circumference of the fixing seat 122, and the back plate 21 protrudes away from the fixing seat; the central axis of the arc-shaped protrusion of the back plate 21 coincides with the central axis of the inner turntable 123. The length extension direction of the back plate 21 is perpendicular to the length direction along the base plate 11. The back plate 21 is made of metal, such as steel. One end of the back plate 21 along its length extension direction is fixedly connected to the side of the base plate 11 near the fixing seat 122 or the inner turntable 123, and the connection method can be welding. Along the thickness direction of the base plate 11, the orthographic projection of the back plate 21 coincides with the orthographic projection of the base plate 11, and the orthographic projection of the back plate 21 is tangent to the orthographic projection of the fixing seat 122. The backrest 21 can be used by the patient to lean on when using this embodiment; for example, when the patient steps up and down the inner turntable 123, the patient can hold the backrest 21 to stabilize the body and enhance the patient's safety when going up and down the inner turntable 123; and the backrest 21 can also provide some support to the patient's back when the patient uses the seat 22, enhancing the patient's safety.

[0074] Furthermore, the backrest 21 has a magnetic suction hole 212 along its thickness direction; the magnetic suction hole 212 is a rectangular shape with an arc bend, and its arc bend and direction are the same as those of the backrest 21. The length extension direction of the magnetic suction hole 212 is the length extension direction of the backrest 21, and its length along the length extension direction of the backrest 21 is not greater than the width of the backrest 21 along the length extension direction of the backrest 21. A magnet 211 is engaged inside the magnetic suction hole 212; the shape of the magnet 211 is an arc that fits the magnetic suction hole 212. The magnet 211 is used to magnetically fix the seat plate 22. The side of the backrest 21 away from the fixing base 122 and the end away from the base plate 11 are screwed to the fixing component 23, and the side of the backrest 21 near the fixing base 122 is hinged to the seat plate 22. Along the width direction Y of the base plate 11, the orthographic projections of the seat plate 22, the magnet 211, and the fixing component 23 do not overlap. The width direction, length direction, and thickness direction of the base plate 11 are perpendicular to each other.

[0075] Continue to refer to Figures 2-6 As shown, the seat 22 is a rectangular plate that has been bent into an arc shape. The seat 22 is hinged to the backrest 21 along its width direction on one side extending along the length of the backrest 21, and its width along the length direction of the backrest 21 is not greater than the width of the backrest 21 along the length direction of the backrest 21. The seat 22 includes an open mode and a folded mode. In the open mode, the seat 22 can be opened away from the backrest 21 around the hinge, and the maximum opening angle between the seat 22 and the backrest 21 is not greater than 90 degrees; at this time, the seat 22 protrudes away from the fixed seat 122. The seat 22 has a first short side 222, which is the side of the seat 22 closest to the hinge. When the seat 22 is opened away from the backrest 21 with the hinge as the pivot axis, the first short side 222 rotates around the hinge. Since the backrest 21 is an arc-shaped plate recessed towards the fixed seat 122, the first short side 222 cannot rotate to 90°, that is, it is limited and blocked by the backrest 21 and cannot continue to rotate. At this time, the seat 22 is in its maximum open mode, and the patient can sit on the side of the seat 22 away from the base plate 11.

[0076] Furthermore, the seat 22 is an arc-shaped plate. When the seat 22 and backrest 21 are in the open mode, the central axis of the arc-shaped bend of the seat 22 extends along the width of the base plate 11. When the seat 22 and backrest 21 are in the folded mode, the central axis of the arc-shaped bend of the seat 22 is parallel to the central axis of the arc-shaped bend of the backrest 21. The arc shape of the seat 22 differs from that of ordinary straight-board and concave seat cushions, which is beneficial for training the patient's abdominal core stability when using the seat in a seated position. Furthermore, the patient can use their legs to clamp and fix the seat 22 on opposite sides along the width of the base plate 11, further enhancing the patient's stability and training the thigh muscles.

[0077] At the end of the seat plate 22 furthest from the hinge, the first short side 222 is engaged with an arc-shaped magnetic block 221 that cooperates with the magnet 211. The magnetic block 221 is a magnetic metal that can be attracted by the magnet 211, such as iron, cobalt, and nickel, or an iron-cobalt-nickel alloy. When the angle between the seat plate 22 and the backrest 21 is 0 degrees, the seat plate 22 and the backrest 21 are parallel to each other. The magnetic block 221 is magnetically attracted by the magnet 211, and the seat plate 22 is attracted by the backrest 21, so that the closure of the seat plate 22 and the backrest 21 can be maintained, allowing the patient to exercise and rehabilitate using only the inner rotating disc 123.

[0078] Continue to refer to Figures 2-7 As shown, the fixing component 23 includes a strip-shaped fixing sub-component 232 and a fixing female-component 231. One end of the fixing sub-component 232 and the fixing female-component 231 along their length is fixed to opposite sides of the backing plate 21 along its length by screws. Specifically, they are fixed to the end of the backing plate 21 away from the base plate 11. In this embodiment, the fixing sub-component 232 and the fixing female-component 231 are fixed to the two apex corners of the backing plate 21 away from the base plate 11; this is not intended to limit the specific connection position of the fixing sub-component 232 and the fixing female-component 231. The distance between the fixing sub-component 232 and the fixing female-component 231 and the base plate 11 is greater than the distance between the seat plate 22 and the base plate 11. The end of the fixing sub-component 232 away from the backrest 21 and the end of the fixing mother component 231 away from the backrest 21 can engage with each other. The backrest 21, the fixing sub-component 232 and the fixing mother component 231 can form a fixed space for fixing the patient's body. When the patient sits on the seat board 22, his waist can be fixed by the fixing sub-component 232 and the fixing mother component 231, which further enhances the safety of use.

[0079] Continue to refer to Figure 2 and Figure 3As shown, the hydraulic assembly 33 includes a cylindrical handle 331, a rectangular small cylinder 332, a rectangular large cylinder, and a circular unloading valve 333. The handle 331 has a cylindrical solid structure, made of high-strength alloy steel, and its length is controlled between 250-350mm, ensuring both comfortable grip during manual operation and the ability to withstand the torque impact of repeated pressing. One end of the handle 331 is connected to the piston rod of the small cylinder 332 via a detachable pin, with a wear-resistant copper sleeve at the connection point to reduce wear caused by long-term rotation. The surface of the end of the handle 331 away from the small cylinder 332 is knurled to increase friction between the hand and the handle 331, preventing safety hazards caused by slippage during operation. The small cylinder 332 is a rectangular sealed cavity structure, integrally molded from cast aluminum, combining lightweight design with high-pressure load-bearing capacity. The small cylinder 332 houses a precision piston with a diameter of 25-30mm. An oil-resistant rubber sealing ring is nested between the precision piston and the cylinder wall of the small cylinder 332 to effectively prevent internal leakage of hydraulic oil and ensure pressure transmission efficiency. The small cylinder 332 is connected to the large cylinder via a high-pressure seamless steel pipe. The large cylinder also has a rectangular structure, its size adapted to the lifting requirements of the telescopic plate 31. The material of the large cylinder is the same as that of the small cylinder 332. A circular push plate is welded to the top of the piston inside the large cylinder to ensure uniform force distribution when in contact with the sub-plate 312, preventing excessive local pressure that could deform the sub-plate 312. The unloading valve 333 is a circular knob-type structure made of brass, which is rust-resistant and has good sealing properties. The unloading valve 333 contains a conical valve core and a return spring. The contact surface between the conical valve core and the unloading valve 333 is precision ground, and a high-pressure seal is achieved in conjunction with an oil-resistant sealing gasket. Optionally, the knob of the unloading valve 333 has anti-slip textures and is marked with "open" and "close" directions. During operation, it is only necessary to rotate it clockwise 1 / 4 turn to open the unloading channel and rotate it counterclockwise to the limit to close it, which facilitates quick control of hydraulic oil return.

[0080] It should be noted that the handle 331, small cylinder 332, large cylinder and drain valve in the hydraulic assembly 33 are all existing technologies in the existing hydraulic field. In this embodiment, only a brief introduction is given, and no further details are provided.

[0081] Continue to refer to Figure 2 and Figure 3 As shown, the telescopic plate 31 includes a hollow mother plate 311 and a daughter plate 312 fitted inside the mother plate 311. Both the mother plate 311 and the daughter plate 312 are cuboid in shape and can be made of steel plate. The mother plate 311 has a daughter plate hole extending along its length at one end near the daughter plate 312. The daughter plate 312 is precisely fitted to the inner wall of the mother plate 311 through the daughter plate hole and extends and retracts vertically along the thickness direction of the base plate 11.

[0082] The mother plate 311 is located near the bottom plate 11 at one end. It is fixed to the bottom of the large cylinder body with bolts. Reinforcing ribs are added around the connection between the mother plate 311 and the large cylinder body to enhance the connection strength. The length of both the mother plate 311 and the large cylinder body extends in the thickness direction of the bottom plate 11. The mother plate 311 is located on the outer side of the abutment plate 21, and its length is parallel to that of the abutment plate 21. The side of the mother plate 311 away from the abutment plate 21 is fixed to the small cylinder body 332 by welding. The weld joint is then ground and coated with anti-rust paint. Circular pipe holes are opened on the mother plate 311 at positions corresponding to the small cylinder body 322 and the large cylinder body. The pipe between the small cylinder body 322 and the large cylinder body passes through these pipe holes for connection.

[0083] Optionally, when the pipe between the small cylinder 322 and the large cylinder passes through the pipe through hole, a rubber sealing ring is installed between the pipe and the pipe through hole to fix the position of the pipe and prevent impurities from entering the interior of the mother plate 311 through the through hole. The angle between the extension direction of the handle 331 and the mother plate 311 is an acute angle, which is between 30° and 60°.

[0084] The mother plate 311 is welded to the base plate 11 on the side near the abutment plate 21. The weld length is consistent with the width of the mother plate 311 along the length extension direction of the abutment plate 21, ensuring that the mother plate 311 and the base plate 11 form a stable integral structure and can withstand the longitudinal impact force when the daughter plate 312 is raised or lowered. The side of the daughter plate 312 near the base plate 11 abuts against the piston push plate of the large cylinder. At the same time, a positioning groove is provided on the side of the daughter plate 312 near the base plate 11. The positioning groove is adapted to the push plate of the large cylinder to prevent the daughter plate 312 from shifting laterally during the raising or lowering process.

[0085] Continue to refer to Figures 2 to 8 As shown, the handrail frame 32 includes a π-shaped frame 321, a C-shaped handrail 322, and a return spring 323; all three are made of metal. The π-shaped frame 321 is parallel to the base plate 11, with its π-shaped opening extending along the width of the base plate 11 towards the central axis of the fixed seat 122. The handrail 322 is a C-shaped bent rod with a circular cross-section. The handrail 322 has an axis of symmetry extending along the width of the base plate 11; the C-shaped bending direction of the handrail 322 is the same as the π-shaped opening direction of the π-shaped frame 321, both facing the fixed seat 122. Along the width of the base plate 11, the axis of symmetry of the π-shaped frame 321 coincides with the axis of symmetry of the handrail 322.

[0086] The ∏-shaped frame 321 includes a horizontal ∏-shaped section and two vertical ∏-shaped sections perpendicularly connected to the horizontal ∏-shaped section. Both the horizontal and vertical ∏-shaped sections are round rods with circular cross-sections perpendicular to the axial direction. The two ends of the horizontal ∏-shaped section are fixed to the side of the sub-plate 312 away from the mother plate 311 by bearings along its length. The horizontal ∏-shaped section can rotate on the sub-plate 312 about its central axis. The two vertical ∏-shaped sections are identical in size and arranged parallel to each other. The length extension direction of the vertical ∏-shaped section is Y, and the length extension direction of the horizontal ∏-shaped section is the same as the length extension direction of the backing plate 21. The ends of the two vertical ∏-shaped sections away from the fixing seat 122 are symmetrically arranged about the axis of symmetry of the horizontal ∏-shaped section along the width extension direction of the base plate 11. The orthographic projections of the two vertical ∏-shaped sections coincide along the length extension direction of the backing plate 21.

[0087] The return spring 323 is a cylindrical metal spring, extending along the width of the abutment plate 21. The return spring 323 is sleeved on the outer wall of the horizontal segment of the Π-shaped plate and is located between the two vertical segments of the Π-shaped plate. The included angle between the two ends of the return spring 323 is less than 90°; the two ends of the return spring 323 along its length are located on opposite sides of the sub-plate 312 along its thickness. The return spring 323 is used to prevent the included angle between the vertical segments of the Π-shaped plate on the horizontal segment and the sub-plate 312 from being less than 30° when the horizontal segment of the Π-shaped plate rotates on the sub-plate 312; that is, to prevent the vertical segments of the Π-shaped plate from moving excessively towards the base plate 11 on the side of the sub-plate 312 closest to the fixing seat 122 when the horizontal segment of the Π-shaped plate drives the vertical segments to rotate; it is also used to prevent the vertical segments of the Π-shaped plate from flipping towards the side of the sub-plate 312 away from the fixing seat 122.

[0088] The hand frame 322 is integrally connected to the ends of the two vertical segments of the Π-shaped shape away from the horizontal segments of the Π-shaped shape. The hand frame 322 is an arc-shaped curved round rod with arc-shaped openings at both ends along its length; the imaginary plane formed by the hand frame 322 and its arc-shaped openings is parallel to the base plate 11. Along the arc length extension direction of the back plate 21, the arc length of the arc-shaped opening is greater than the arc length of the back plate 21; along the thickness direction of the base plate 11, the orthographic projection of the foot groove 124 coincides with the imaginary plane formed by the hand frame 322 and its arc-shaped openings. The patient can grasp the two ends of the hand frame 322 along its length direction and pull the hand frame 322 towards the base plate 11 along the thickness direction of the base plate 11, thereby exercising the patient's hands and chest. After the scaffold 322 is pulled, one end of the return spring 323 abuts against the side of the subplate 312 near the fixed seat 122 and deforms. After the force applied to the scaffold 322 is released, the scaffold 322 automatically returns to the horizontal position.

[0089] Continue to refer to Figures 2 to 9 As shown, the load transmission assembly 34 includes a Y-shaped traction rope 341, a hollow cuboid fixed shell 342, a cuboid load block 343, a cylindrical fixed rod 345, a pin 346, and a sliding rod 347.

[0090] The fixed shell 342 is a hollow rectangular body with four sides, the other two sides of which are formed by the mother plate 311 and the ground. The fixed shell 342 includes a left side plate and a right side plate that are relatively parallel, and a top side plate and a rear side plate that are perpendicular to each other; the left side plate, right side plate, top side plate and rear side plate are all rectangular plates with a thickness of no more than 10mm, and their materials can be plastic or metal. The rear side plate is parallel to the mother plate 311 and is located on the side of the mother plate 311 away from the back plate 21 or the fixing seat 122. The left side plate, right side plate, top side plate and rear side plate are integrally formed and further connected to part of the mother plate 311 to form a hollow shell; the left side plate, right side plate and top side plate can be connected to the mother plate 311 by welding. The hollow rectangular body formed by the fixed shell 342 and the mother plate 311 contains a load block 343, a fixing rod 345, a pin 346 and a sliding rod 347, and a traction rope 341 runs through the interior and exterior of the fixed shell 342. Specifically, the rear side plate has a rectangular adjustment through hole 3421 along its thickness direction, with its length extending in the thickness direction of the base plate 11. The area of ​​the adjustment through hole 3421 is smaller than the area of ​​the rear side plate. The adjustment through hole 3421 is used to expose the load block 343 and the pin 346, allowing the user to insert or remove the pin 346 inside the fixed shell 342 through the adjustment through hole 3421. The upper side plate is located near the sub-plate 312 and is perpendicularly connected to the left side plate, right side plate, and rear side plate. The upper side plate has a circular traction through hole along its thickness direction, through which the traction rope 341 passes through the traction through hole and runs horizontally through the interior and exterior of the fixed shell 342.

[0091] A sliding rod 347 is fixedly connected to the side of the upper side plate away from the sub-plate 312, and the connection method can be screw fixing. The sliding rod 347 is a hollow round rod, and its inner wall near the upper side plate is provided with threads. The end of the sliding rod 347 near the upper side plate is fixed to the upper side plate with screws. The length of the sliding rod 347 extends in the thickness direction of the base plate 11, and its length is equal to the height of the upper side plate near the ground from the ground. Along the length extension direction of the back plate 21, the sliding rod 347 includes a parallel first sliding rod 3471 and a second sliding rod 3472. The first sliding rod 3471 and the second sliding rod 3472 have the same structure and size, and are both fixed to the upper side plate with screws. The first sliding rod 3471 and the second sliding rod 3472 are arranged in the width extension direction of the back plate 21; a weight block 343 is sleeved on the outer wall of the first sliding rod 3471 and the second sliding rod 3472; the weight block 343 slides along the thickness direction of the base plate 11 on the outer wall of the first sliding rod 347 and the second sliding rod 3472.

[0092] The weight block 343 is a cuboid, and its material can be plastic or metal. The weight block 343 has a first sliding hole 3431, a second sliding hole 3432, and a through hole 3433 along its thickness direction. All three holes are circular, with the radius of the through hole 3433 being smaller than that of either the first or second sliding hole 3431. The first and second sliding holes 3431 and 3432 are used to insert the first sliding rod 3471 and the second sliding rod 3472, respectively. The weight block 343 slides on the first and second sliding rods 3471 and 3472 through the first and second sliding holes 3431 and 3432. The connecting line between the first and second sliding holes 3431 and 3432 is along the length of the weight block 343 and also along the width extension direction of the backing plate 21. The through hole 3433 is used to insert the fixing rod 345. Several weight blocks 343 are provided along the thickness direction of the base plate 11. The first sliding holes 3431 of at least two weight blocks 343 are sequentially connected to the outer wall of the first sliding rod 3471. In this embodiment, 20 weight blocks 343 are used as an example. The second sliding holes 3432 of the 20 weight blocks 343 are sequentially connected to the outer wall of the second sliding rod 3472. Furthermore, the through holes 3433 of the 20 weight blocks 343 are sequentially connected to the outer wall of the fixed rod 345.

[0093] One end of the limiting post 3451 near the upper side plate is fixedly connected to the traction rope 341; the traction rope 341 is a Y-shaped steel rope. The Y-shaped intersection of the traction rope 341 is located on the side of the traction through hole away from the load block 343; that is, along the thickness direction of the base plate 11, the sum of the length of the end of the traction rope 341 near the limiting post 3451, the height of the limiting post 3451, and the length of the fixing rod 345 is greater than the height of the fixing shell 342. The two ends of the traction rope 341 near the horizontal segment of the π are respectively wound and fixed to the two ends of the horizontal segment of the π; the traction rope 341 is fully stretched from the horizontal segment of the π to the area of ​​the limiting post 3451, with no winding sections.

[0094] Along the thickness direction of the base plate 11, the length of the fixing rod 345 is greater than the sum of the thicknesses of the 20 load-bearing blocks 343. The fixing rod 345 is used to lock the relative number of load-bearing blocks 343. A cylindrical limiting post 3451 is provided at one end of the fixing rod 345 near the upper side plate. The radius of the limiting post 3451 is greater than the radius of the through hole 3433. The limiting post 3451 is used to prevent the load-bearing blocks 343 from slipping off the fixing rod 345 along the thickness direction of the base plate 11. Along the width extension direction of the base plate 11, the fixing rod 345 has at least two first limiting holes 3452 along the length direction of the base plate 11. The first limiting holes 3452 are circular through holes. The first limiting holes 3452 penetrate the fixing rod 345 along the length direction of the base plate 11, and at least two circular first limiting holes 3452 are arranged at equal intervals along the length direction of the fixing rod 345. Along the thickness direction of the base plate 11, the distance between two adjacent first limiting holes 3452 is equal to the thickness of the weight block 343 along the thickness direction of the base plate 11. Each weight block 343 has a second limiting hole 3434 matching the first limiting hole 3452 along the length direction of the base plate 11. The second limiting hole 3434 is a circular through hole. Each weight block 343 has a second limiting hole 3434. Along the thickness direction of the base plate 11, the orthographic projections of the second limiting holes 3434 on each weight block 343 coincide with each other, and the orthographic projections of each first limiting hole 3452 on the fixing rod 345 coincide with each other. The number of openings of the first limiting holes 3452 is equal to the number of second limiting holes 3434 or the number of weight blocks 343. A cylindrical pin 346 is inserted into the second limiting hole 3434 and the corresponding first limiting hole 3452.

[0095] The pin 346 simultaneously passes through a first limiting hole 3452 on the fixing rod 345 and one of the load blocks 343. The pin 346 is a cylindrical metal rod that extends along the width of the base plate 11. When the pin 346 is inserted into the first limiting hole 3452 and one of the load blocks 343 on the fixing rod 345, it fixes the load block 343 and all the fixing blocks on one side away from the base plate 11 to the fixing rod 345. When the scaffold 322 is pulled, all the aforementioned load blocks 343 fixed by the pin 346 rise away from the base plate 11 against gravity.

[0096] In its specific implementation, this embodiment can be used for rehabilitation treatment after neurosurgical procedures such as traumatic brain injury, cerebral hemorrhage, cerebral aneurysm, and brain tumor. The specific operation is as follows:

[0097] First, press down the handle 331 along the thickness direction of the base plate 11 at the fixed point of the handle 331, shake the hydraulic component 33, and adjust the relative length of the sub-plate 312 and the mother plate 311 to suit the patient's specific height; specifically, adjust the height of the side of the sub-plate 312 away from the mother plate 311 to the height of the hand frame 322 and the patient's shoulder blade.

[0098] The second step involves the patient facing the backrest 21, placing both hands on either side of the backrest 21 away from the base plate 11. While holding onto the backrest 21, the patient lifts their feet onto the inner turntable 123, aligning their left and right feet with the two foot slots 124 respectively. The patient can then twist their waist and lower body while holding onto the backrest 21, performing a twisting exercise on their waist and lower body. After completing the twisting exercise, the patient can walk off the inner turntable 123 while still holding onto the backrest 21.

[0099] Thirdly, the patient can open the seat 22 from the backrest 21 away from the base plate 311; along the thickness direction of the base plate 11, the orthographic projection of the inner turntable 123 coincides with the inner projection of the seat 22. At this time, the patient sits on the seat 22 with both legs placed on both sides of the seat 22 along the width extension direction of the base plate 11, and both feet in contact with the ground. At this time, the angle between the backrest 21 and the seat 22 is less than 90°, and the patient has a natural tendency to slide towards the backrest 21, making the patient's sitting posture more stable. Furthermore, the fixing sub-component 232 and the fixing base plate 231 are respectively engaged around the patient in front, fixing the patient's body in the gap formed by the backrest 21, the fixing sub-component 232, and the fixing base plate 231; this further enhances the patient's stability. The patient can hold the handrail 322 at both ends along its length, then pull the handrail 322 towards the base plate 11 along its thickness, and then release it; repeating the pulling and releasing steps will exercise the patient's chest and arms.

[0100] During a mild training session, the patient can simply sit on the seat board 22 and enhance their core control by maintaining posture on the curved seat board 22. Stability is trained by adjusting the amount of contact between their feet and the base plate 11.

[0101] In an enhanced training process, the patient can adjust the position of the pin 346 in different limiting holes 340 and adjust the number of weight blocks 343 fixed on the fixing rod 345, thereby adjusting the weight of the weight blocks 343 that need to be overcome when the frame 322 is flipped. The difficulty of flipping the frame 322 can be adjusted by the pin 346, the weight blocks 343 and the traction rope 341, thus meeting the patient's advanced training needs.

[0102] Compared with the prior art, the postoperative medical rehabilitation device provided in this embodiment achieves at least the following beneficial effects:

[0103] First, the postoperative medical rehabilitation equipment provided in this embodiment can meet various exercise needs and promote rehabilitation at various stages. Firstly, this embodiment provides an arc-shaped seat 22, allowing patients with weaker physical strength to perform only balance rehabilitation training. Furthermore, lumbar twisting can be performed via the inner turntable 123 and ball bearings 121 to meet the training needs of the lumbar and lower limbs. Then, the patient's back, chest, and arms can be trained by pulling the hand frame 322. In addition, the hand frame 322 can be adjusted for weight by the weight block 343, allowing it to meet more advanced rehabilitation needs. The seat 22, inner turntable 123, hand frame 322, and weight block 343 work together to meet almost all the needs of patients from the initial to the later stages of rehabilitation training, satisfying the combined training needs of the patient's upper and lower limbs.

[0104] Secondly, the postoperative medical rehabilitation equipment provided in this embodiment is safe and stable to use, and has a complete protection system. First, this embodiment provides a backrest 21, which allows the patient to easily gain leverage when using the inner turntable 123, enhancing the patient's stability. It also provides back support when the patient is stretching the hand frame 322, facilitating proper back muscle activation and posture correction. Furthermore, this embodiment provides a fixing sub-component 232 and a fixing mother-component 231 to fix the patient's sitting posture, preventing them from slipping off the left board when using the hand frame 322. Additionally, this embodiment provides a foot groove 124 on the inner turntable 123, making it more compatible with the patient's feet and increasing safety. Moreover, the upper rail 125 and lower rail 126 enable directional circular motion of the ball bearings 121, preventing deviation and ensuring the load on the inner turntable 123 is evenly distributed at the contact points between the ball bearings 121 and the rails, improving the rotational efficiency of the inner turntable 123 via the ball bearings 121 and enhancing the stability during patient use.

[0105] Third, the postoperative medical rehabilitation equipment provided in this embodiment can meet the needs of patients of different heights and is easy to adjust and use. Firstly, the sub-plate 312 and the mother plate 311 provided in this embodiment can be adjusted relative to each other to accommodate different patient heights, ensuring that the specific height of the hand frame 322 is suitable for the specific needs of different patients. Furthermore, the extension and retraction adjustment of the sub-plate 312 and the mother plate 311 is simple, requiring only the cranking of the handle 331 of the hydraulic component 33, making adjustment quick and easy. In addition, the connection structure of the pin 346, the weight block 343, and the fixing rod 345 provided in this embodiment also makes the load adjustment of the hand frame 322 convenient and quick.

[0106] In one alternative embodiment, continue to refer to Figures 2-4 as well as Figure 11 As shown, Figure 11 yes Figure 4 Enlarged view at point B; A hollow annular limiting ring 1221 is welded to the side of the fixed base 122 away from the base plate 11, and the inner diameter of the limiting ring 1221 is smaller than the outer diameter of the inner turntable 123; A hollow annular snap-fit ​​ring 1231 is welded to the side of the inner turntable 123 near the base plate 11; Along the thickness direction of the base plate 11, the orthographic projection of the snap-fit ​​ring 1231 and the orthographic projection of the upper track 125 or the lower track 126 do not overlap.

[0107] The cross-sectional shape of the snap ring 1231 perpendicular to its length direction is L-shaped; the inner right angle of the L-shape of the snap ring 1231 forms a snap gap with the periphery of the inner turntable 123, and the limit ring 1221 is snapped in the snap gap.

[0108] Specifically, a hollow annular retaining ring 1221 is welded to the side of the fixing base 122 away from the base plate 11. The retaining ring 1221 has a rectangular cross-sectional shape in any direction perpendicular to its circumference. The outer diameter of the retaining ring 1221 is equal to the inner diameter of the upper opening of the fixing base 122; the retaining ring 1221 is made of the same material as the fixing base 122 and is integrally connected to it. The inner diameter of the retaining ring 1221 is smaller than the outer diameter of the inner turntable 123, and the retaining ring 1221 is used to engage and fix the inner turntable 123 along the thickness direction of the base plate 11. Specifically, a hollow annular locking ring 1231 is welded to the side of the inner turntable 123 closest to the base plate 11. The locking ring 1231 has an L-shaped cross-section in any direction perpendicular to its circumference; the inner right angle of the L-shape of the locking ring 1231 faces the retaining ring 1221. The inner diameter of the locking ring 1231 is larger than the outer diameter of the upper track 125 or the lower track 126; along the thickness direction of the base plate 11, the orthographic projection of the locking ring 1231 and the orthographic projection of the upper track 125 or the lower track 126 do not overlap. The outer diameter of the locking ring 1231 is smaller than the outer diameter of the limiting ring 1221, but larger than the inner diameter of the limiting ring 1221. The L-shaped inner right angle of the locking ring 1231 forms a locking gap with the periphery of the inner turntable 123. The locking gap is a hollow ring that matches the shape and size of the limiting ring 1221, and the limiting ring 1221 is locked within the locking gap. The locking gap formed by the locking ring 1231 and the inner turntable 123 is used to prevent the inner turntable 123 from moving away from the base plate 11 along the thickness direction of the base plate 11.

[0109] The above solution prevents the inner turntable 123 from detaching from the base plate 11 and the fixing seat 122 along the thickness direction of the base plate 11. First, along the thickness direction of the base plate 11, the upper rail 125, lower rail 126, and ball bearings 121 provide support for the inner turntable 123. Then, in the opposite direction of the thickness direction of the base plate 11, the limiting ring 1221 on the fixing seat 122 provides resistance to the movement of the locking ring 1231 of the inner turntable 123. The combined effect of the support force and the resistance ensures that the inner turntable 123 can only rotate in the horizontal direction.

[0110] In one alternative embodiment, continue to refer to Figure 2 , Figure 3 and Figure 12 As shown, Figure 12 This is a partial structural diagram of the base plate provided by this utility model; an S-shaped anti-slip texture 111 is pressed on the side of the base plate 11 near the fixing seat 122; there are at least 10 anti-slip textures 111, and the at least 10 S-shaped anti-slip textures 111 are arranged in a matrix.

[0111] Specifically, the base plate 11 is made of metal, and its smooth surface makes it easy to fall. Anti-slip textures 111 are forged onto the side of the base plate 11 near the turntable 12. The anti-slip textures 111 are S-shaped; alternatively, the shape of the anti-slip textures 111 can also be wavy, snowflake-shaped, circular, or complex intricate curves. This embodiment only uses an S-shape as an example and is not intended to limit the shape of the anti-slip textures 111. At least 10 anti-slip textures 111 are provided on the base plate 11, and the at least 10 S-shaped anti-slip textures 111 are arranged in a matrix, covering the entire side of the base plate 11 near the turntable 12.

[0112] The above solution can effectively increase the roughness of the side of the base plate 11 near the fixed seat 122 and reduce the smoothness of the metal surface of the base plate 11, thereby enhancing the safety of the patient when walking on and off the base plate 11 and preventing the patient from slipping.

[0113] In one alternative embodiment, continue to refer to Figures 2-6 As shown, the seat plate 22 has four fixed corners 223 glued to the end away from the hinge; the fixed corners 223 are triangular prisms, and their height extends in the thickness direction of the seat plate 22; the fixed corners 223 include a first side, a second side, and a third side; the first side, the second side, and the third side are perpendicular to each other to form a three-dimensional right angle, the third side is parallel to the bottom surface of the seat plate 22, and the side of the first side and the second side away from the third side is glued to the seat plate 22.

[0114] The three-dimensional right angles of the seat 22 and the four fixed corners 223 engage with the four apex corners of the magnetic block 221.

[0115] Specifically, four fixed corners 223 are glued to the side of the seat plate 22 away from the backrest 21 and the end away from the hinge. The four fixed corners 223 are identical in structure and size; they are all triangular prisms, and their height extends in the thickness direction of the seat plate 22. The fixed corners 223 are made of plastic and specifically include a first side, a second side, and a third side; the first and second sides are rectangular pieces, and the third side is a triangular piece. The thickness of the first, second, and third sides is no greater than 2mm. The first, second, and third sides are perpendicular to each other and integrally formed, constituting a three-dimensional right angle. The four right angles are used to engage the four apex corners of the magnetic block 221. The third side is parallel to the seat plate 22. The side of the first and second sides away from the third side is glued to the bottom of the groove of the seat plate 22, and one side of each of the first and second sides overlaps with the groove wall of the seat plate 22. The overlapping side of the first and second sides is further glued to the seat plate 22.

[0116] The above scheme can achieve the engagement and fixation of the seat plate 22 and the magnetic block 221, so that the four top corners of the magnetic block 221 away from the bottom of the groove of the seat plate 22 can be fixed in the rectangular groove of the seat plate 22 by the spatial right angle of the four fixing angles 223.

[0117] Example 2

[0118] This embodiment is an extension of embodiment 1, and will continue to be referred to... Figures 2-7 As shown, the fixing sub-component 232 includes a strip-shaped sub-strip 2321 and a three-pronged tongue 2322, and the fixing female component 231 includes a strip-shaped female strip 2311 and a cuboid-shaped insert box 2312.

[0119] The three-pronged tongue 2322 is made of plastic. One side of the three-pronged tongue 2322 has three legs, and the end away from the three legs has a rectangular fixing hole that passes through the three-pronged tongue 2322. One end of the sub-belt 2321 along its length is threaded to the end of the back plate 21 away from the base plate 11. The end of the sub-belt 2321 away from the back plate 21 is movably connected to the three-pronged tongue 2322 through the fixing hole.

[0120] The interior of the insert box 2312 is hollow. The insert box 2312 has arc-shaped grooves on both sides along its length that match the three-pronged tongue 2322. The insert box 2312 has a rectangular connecting hole at one end along its length. The female tape 2311 is threaded to the end of the back plate 21 away from the bottom plate 11 at one end along its length. The end of the female tape 2311 away from the back plate 21 is fixedly connected to the insert box 2312 through the connecting hole. The three-pronged tongue 2322 is inserted into the insert box 2312.

[0121] Specifically, the three-pronged tongue 2322 is made of plastic, possessing excellent wear resistance and impact resistance, and maintaining structural stability during long-term use. One side of the three-pronged tongue 2322 has three parallel legs, distributed along its width. The tips of the three legs, furthest from the child tape, are rounded, facilitating insertion into the insert box 2312 and reducing wear on the inner wall of the insert box 2312. A rectangular fixing hole is provided at the end of the three-pronged tongue 2322 furthest from the three legs. The size of the fixing hole is adapted to the width and thickness of the child tape 2321, ensuring that the child tape 2321 can pass smoothly without easily slipping off. One end of the sub-belt 2321 along its length is fixedly connected to the end of the back plate 21 away from the base plate 11 by screws. The sub-belt 2321 is made of tensile-resistant polyester material, which enhances the strength of the connection. The end of the sub-belt 2321 away from the back plate 21 passes through the fixing hole and is folded back and wrapped. The sub-belt 2321 is movably connected to the three-pronged tongue 2322 by wrapping. This connection method can adjust the effective length of the sub-belt 2321 according to actual needs to meet different usage scenarios.

[0122] The insert box 2312 is also made of plastic, matching the material of the three-pronged tongue 2322. When the two are inserted together, there will be no excessive wear or chemical reaction due to material differences. The interior of the insert box 2312 is hollow, forming a cavity to accommodate the three-pronged tongue 2322. Along its length, the insert box 2312 has arc-shaped grooves on both sides that match the three-pronged tongue 2322. The curvature of these grooves perfectly matches the outer contours of the two legs of the three-pronged tongue 2322 along its width. When the three-pronged tongue 2322 is inserted into the insert box 2312, the legs can accurately fit into the arc-shaped grooves, achieving initial positioning and limiting, preventing the three-pronged tongue 2322 from wobbling freely within the insert box 2312. The insert box 2312 has a rectangular connecting hole at one end along its length. The size of the connecting hole corresponds strictly to the width and thickness of the female tape 2311. The end of the female tape 2311 away from the backing plate 21 passes through the connecting hole, folds back and wraps around, and is fixedly connected to itself by sewing.

[0123] Through the above design, the three legs of the tripod tongue 2322 precisely engage with the arc-shaped groove of the insert box 2312, forming a limiting position and ensuring a stable connection between the fixing component 232 and the fixing component 231 during use, preventing them from easily loosening. The sub-belt 2321 passes through the fixing hole of the tripod tongue 2322 and is movably connected, allowing for easy adjustment of its length to meet different usage length requirements. The plug-in design of the tripod tongue 2322 and the insert box 2312 simplifies assembly and disassembly, eliminating the need for complex tools and improving ease of use.

[0124] The various technical features of this utility model are mutually complementary and functionally supportive of each other. In other words, the technical solution is not a "simple superposition" of technical features among multiple prior art documents. Therefore, this utility model does not fall under the category of "simple superposition" in Chapter 4 of Part II of the Patent Examination Guidelines.
