Specifically, when the first locking member is disconnected from the first support portion, the first support portion is rotatable about a rotation axis by an external force; when the first locking piece is connected with the first supporting part and the external force is cancelled, the first supporting part stops rotating and the included angle between the first supporting part and the second supporting part is kept. Then, the first supporting part is connected with the body of the patient by utilizing the wrapping belt or other devices, for example, the joint to be trained is a knee joint, the first supporting part can be connected with the shank of the patient through the wrapping belt, the second supporting part can be connected with the thigh of the patient through the other wrapping belt, and thus the tissue adjusting device is convenient for the patient to wear, and inconvenience caused by rotation of the first supporting part in the wearing process is avoided.

Further, when the first locking member is disconnected from the first supporting portion and the first supporting portion rotates under the action of external force, the first elastic member is stretched, and when the first locking member is connected with the first supporting portion, the first elastic member is prevented from releasing elastic potential energy; and the driving part or the first supporting part is used for receiving the external force.

To make the objects, advantages and features of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention. The same or similar reference numbers in the drawings identify the same or similar elements.

Referring to fig. 1 to 7, a tissue adjusting device according to an embodiment of the present invention includes a first supporting portion 1000, a second supporting portion 2000, a driving portion 3000, and a transmission portion. The driving part 3000 is rotatably connected to the first supporting part 1000 and the second supporting part 2000, respectively. The transmission part includes a first elastic member 4100, a first locking member 4200, and a draft assembly 4300. The first elastic member 4100 has one end connected to the first supporting part 1000 and the other end connected to the first locking member 4200. One end of the draft assembly 4300 is connected to the first locking member 4200, and the other end is connected to the driving part 3000. The first locking member 4200 is selectively coupled to or decoupled from the first support 1000 to control the rotation of the first support 1000. Specifically, when the first locking member 4200 is disconnected from the first support 1000, the first support 1000 can rotate around a rotation axis under an external force to change an angle of an included angle between the first support 1000 and the second support 2000. When the first locking member 4200 is coupled to the first support 1000 and the external force is removed, the first support 1000 stops rotating so that the angle of the included angle between the first support 1000 and the second support 2000 is maintained. The driving portion 3000 is configured to receive the external force and drive the first supporting portion 1100 to rotate, or the first supporting portion 1100 directly receives the external force and rotates.

The tissue adjusting device is used for rehabilitation training of joints with stretching or bending obstacles caused by soft tissue contracture, fibrous adhesion and the like, wherein the joints can be knee joints, elbow joints, wrist joints, ankle joints and the like. For convenience, the rehabilitation training of the knee joint using the tissue conditioning device is described as an example, but those skilled in the art can modify the following description to adapt it to other joint rehabilitation training situations.

The tissue conditioning device may also include a first wrapping strip 5100 and/or a second wrapping strip 5200. The first supporting part 1000 is connected with the lower leg of the patient through the first wrapping band 5100, the second supporting part 2000 is connected with the upper leg of the patient through the second wrapping band 5200, and then the lower leg is driven to rotate around the knee joint through the rotation of the first supporting part 1000, so that the extension exercise or the flexion exercise can be further performed. In this embodiment, the first supporting portion 1000 may rotate in a first direction around the rotation axis, or may rotate in a second direction around the rotation axis, the second direction being opposite to the first direction. Specifically, when the first direction is a counterclockwise direction, the second direction is correspondingly a clockwise direction; when the first direction is a clockwise direction, the second direction is a counterclockwise direction. After the patient wears the tissue adjusting device, the first supporting portion 1000 is rotated in the first direction, so that the patient can perform flexion movement, the first supporting portion 1000 can move in the second direction, and the patient can perform extension movement. That is, the patient is selectively subjected to flexion or extension movements by controlling the rotation direction of the first support 1000.

In the initial state, an angle is formed between the first supporting portion 1000 and the second supporting portion 2000, and the initial angle of the angle is, for example, 180 ° (as shown in fig. 1). However, in general, the tissue conditioning device in its initial state is not adapted to the actual conditions of the patient. Therefore, the user needs to adjust the angle of the included angle between the first supporting portion 1000 and the second supporting portion 2000 to adapt the included angle to the actual condition of the patient. That is, the first locking member 4200 is disconnected from the first support 1000 and an external force is applied to the driving part 3000 or the first support 1000 to drive the first support 1000 to rotate in the first direction around the rotation axis until the angle between the first support 1000 and the second support 2000 is at a proper angle. The angle can then be maintained by coupling the first locking member 4200 to the first support 1000, and the tissue adjustment device can then be conveniently applied to the area to be trained on the patient. In this process, the first elastic member 4100 is stretched.

Preferably, when the first locking member 4200 is disconnected from the first support 1000 and the first support 1000 rotates under the action of external force, the one end of the drafting assembly 4300 is also moved in the direction close to the rotation axis, which in turn drives the first locking member 4200 to move in the direction close to the rotation axis, so that the first elastic member 4100 is stretched and stores elastic potential energy. When the first locking member 4200 is connected to the first support 1000 and the external force is removed, the first locking member 4200 stops moving and remains stationary relative to the first support 1000, thereby preventing the first elastic member 4100 from releasing its elastic potential energy, so as to keep the first elastic member 4100 in a stretched state.

After the patient wears the tissue adjustment device, the user can disengage the first locking member 4200 from the first support 1000 and apply an external force to the driving portion 3000 to drive the first support 1000 to rotate about the rotation axis in a first direction to drive the patient's knee joint to a flexion motion. Alternatively, an external force is applied to the driving part 3000 to drive the first supporting part 1000 to rotate around the rotation axis in the second direction, so as to perform an extension motion of the knee joint of the patient. Since the first elastic member 4100 is stretched before the patient wears the tissue adjusting device, the stretching assembly 4300 is necessarily tightened and can directly transmit the acting force, so that the first supporting part 1000 can quickly respond to the driving of the driving part 3000, and the rotation precision of the first supporting part 1000 is improved.

Furthermore, it will be understood by those skilled in the art that if the elastic potential energy stored by the first elastic member 4100 when adjusting the included angle between the first supporting portion 1000 and the second supporting portion 2000 of the tissue adjusting device to a proper angle is large enough, after the patient wears the tissue adjusting device, the first locking member 4200 can be disconnected from the first supporting portion 1000, and the external force applied to the driving portion 3000 is stopped, so that the first supporting portion 1000 can be driven in the first direction around the rotation axis by releasing the stored elastic potential energy by the first elastic member 4100 (so that when adjusting the included angle between the first supporting portion 1000 and the second supporting portion 2000, the external force is received by the driving portion 3000 to rotate the first supporting portion 1000 in the first direction as a precondition) or in the second direction (so that when adjusting the included angle between the first supporting portion 1000 and the second supporting portion 2000, the first supporting portion 1000 directly receives the external force and rotates in the first direction) to drive the knee joint to perform flexion or extension movement.

The type of the first locking member 4200 matches the specific configuration of the first support 1000, for example, in some embodiments, the first support 1000 is elongated and extends in a third direction that is perpendicular to the direction of the rotation axis. At least one locking hole group is provided on the first supporting portion 1000, each locking hole group includes a plurality of locking holes 1001 arranged at intervals in the third direction, and the first locking member 4200 is close to or far from the rotation axis in the third direction. The first locking member 4200 may be configured as a pogo pin mechanism (a specific structure will be described later), and is configured to pass through the locking hole 1001, and when the first locking member 4200 passes through the locking hole 1001, the first locking member 4200 is coupled to the first support part 1000, and when the first locking member 4200 is disengaged from the locking hole 1001, the first locking member 4200 is decoupled from the first support part 1000. As can be appreciated by those skilled in the art, during the rehabilitation training process after the patient wears the medical device tissue conditioning device, said first lock member 4200 is movable in said third direction (said first lock member 4200 is moved closer to said rotation axis in said first direction when rehabilitation training is performed by applying external force to said drive part 3000, said first lock member 4200 is moved away from said rotation axis in said first direction when rehabilitation training is performed by releasing elastic potential energy from said first elastic member 4100) and can pass through said plurality of lock holes 1001, and each time the first locking member 4200 passes through one of the locking holes 1001, the first locking member 4200 automatically passes through the corresponding locking hole 1001 by its own elastic force to connect the first locking member 4200 with the first supporting part 1000, this causes the training process to pause, thus requiring the user to maintain or intermittently perform the operation of disconnecting.

Further, the draft assembly 4300 of the present invention preferably includes a second elastic member 4310 and a force transmission cable 4320, wherein one end of the second elastic member 4310 is connected to the first locking member 4200, the other end of the second elastic member 4310 (i.e. the end far away from the first locking member 4200) is connected to one end of the force transmission cable 4320, and the other end of the force transmission cable 4320 is connected to the driving portion 3000. The tissue adjusting device is configured such that when the first locking member 4200 is disconnected from the first support part 1000 and the first support part 1000 is rotated about the rotation axis by an external force, the second elastic member 4310 is maintained in an original state, so that the force transmission cable 4320 is in a tensioned state, and the second elastic member 4310 directly moves the first locking member 4200 in a direction close to the rotation axis. Here, the original state of the second elastic member 4310 refers to a state of the second elastic member 4310 before the first support part 1000 rotates, for example, the second elastic member 4310 is in an original length before the first support part 1000 rotates, and the second elastic member 4310 maintains the original length when the first support part 1000 rotates. That is, during the process of adjusting the included angle between the first support part 1000 and the second support part 2000 to the proper angle, the second elastic part 4310 is not deformed, only the first elastic part 4100 is stretched, and the force transmission cable 4320 is kept in a tight state. To achieve this, the elastic coefficient of the second elastic member 4310 should be larger than the elastic coefficient of the first elastic member 4100, and the specific values of the elastic coefficient of the second elastic member 4310 and the elastic coefficient of the first elastic member 4100 are not limited in the embodiments of the present invention as long as both satisfy the aforementioned requirements.

And, the tissue adjusting device is further configured to, when the first locking member 4200 is connected to the first support part 1000 and the driving part 3000 drives the other end of the force transmission cable 4320 to rotate around the rotation axis under the action of external force, move the one end of the force transmission cable 4320 in the direction close to the rotation axis and bring the one end of the second elastic member 4310 away from the first locking member 4200 in the direction close to the rotation axis, so that the second elastic member 4310 is stretched and stores elastic potential energy, and simultaneously drive the first support part 1000 to rotate around the rotation axis in the first direction (or the second direction), so that the knee joint can be subjected to flexion (or extension) motion. Not only here, when the external force is cancelled, the second elastic member 4310 also releases its stored elastic potential energy, and drives the first support part 1000 to continue to rotate in the first direction about the rotation axis (based on when the driving part 3000 drives the first support part 1000 to rotate in the first direction under the external force) to continuously perform the flexion or extension motion. In this way, when the tissue adjustment device is used for rehabilitation training of the knee joint, since the first locking member 4200 and the first support 1000 are always connected, the first support 1000 can be driven to rotate only by the deformation of the second elastic member 4310, and the operation of releasing the connection between the first locking member 4200 and the first support 1000 is not required to be maintained or intermittently performed, which simplifies the use. Further, the second elastic element 4310 releases elastic potential energy to continue rehabilitation training, so that the rehabilitation training can be performed during sleep time, a patient does not need to reserve special time, and the use is more flexible.

In this embodiment, it is preferred that the first elastic element 4100 is always in tension because, when the force transmission cable 4320 is loose for long term use, the force transmission cable 4320 can be compensated by releasing the connection between the first locking element 4200 and the first support 1000 to release at least part of the elastic potential energy of the first elastic element 4100, so that the force transmission cable 4320 is kept in tension, so that the first elastic element 4100 can be stretched and the force transmission cable 4320 can transmit force quickly upon rotation of the first support 1000.

It should be noted that, although the angle between the first supporting portion 1000 and the second supporting portion 2000 is 180 ° in the initial state, the maximum rotation angle of the first supporting portion 1000 around the rotation axis is generally less than 180 ° (i.e. the angle between the first supporting portion 1000 and the second supporting portion 2000 is not 0), for example, 140 °.

Further, the driving portion 3000 is configured to rotate around the rotation axis by an external force. Also, the tissue adjusting apparatus may further include a second locker for locking the first support 1000 and the driving part 3000 to prevent a relative rotation between the first support 1000 and the driving part 3000. When the first locking member 4200 is connected to the first support 1000, the first support 1000 and the driving portion 3000 are locked by the second locking member, so that the driving portion 3000 directly drives the first support 1000 to rotate. As known to those skilled in the art, in the process that the driving portion 3000 directly drives the first support portion 1000 to rotate, the whole drafting assembly 4300 rotates around the rotation axis along with the first support portion 1000, and the first elastic element 4100 and the second elastic element 4310 are not deformed, so that the user can provide a small external force to rotate the first support portion 1000.

Further, the tissue adjusting device preferably further comprises an angle indicating mechanism for indicating an angle of rotation of the first support 1000 about the rotation axis.

The second supporting portion 2000 also has a long bar shape, and extends along a radial direction of the driving portion 3000 (i.e., the first direction). The second support part 2000 is formed with a second coupling hole 2001, and the center shaft 3200 passes through the second coupling hole 2001 to rotatably couple the driving part 1000 with the second support part 2000. Specifically, the second support 2000 includes a second mount 2100 and a second housing 2200, the second mount 2100 includes a second frame 2110 and a coupling plate 2120 coupled to each other, and the coupling plate 2120 has the second coupling hole 2001 formed thereon. The second frame 2110 has a first mounting groove with an opening facing the driving portion 3000, and the second frame 2110 is further provided with a third connecting hole 2002 communicating with the first mounting groove.

In addition, the tissue adjusting device may further include a first clamping ring 6001, the first clamping ring 6001 is disposed on a side of the cover plate 1120 away from the connecting plate 2120 and is connected to the central shaft 3200, so as to prevent the cover plate 1120 and the connecting plate 2120 from disengaging from the central shaft 3200. And, the second locking member may include a first insert nut 7100 and a screw (not shown) provided on the cover plate 1120, and when the screw is coupled with the first insert nut 7100 and is also pressed against the driving plate 3120, the first support part 1000 and the driving part 3000 are locked.

The tissue conditioning device may further include a power input portion for receiving an external force and transmitting the external force to the driving portion 3000. Optionally, the carousel assembly 3100 comprises a worm gear 3110 and a drive disc 3120, the worm gear 3110 being connectable to the central shaft 3200 by keys 3001. The power input portion includes a worm 8100, and the worm 8100 is engaged with the worm wheel 3110. The worm 8100 specifically includes a worm body 8110 and a worm tensioning pin 8120, the worm body 8110 is engaged with the worm wheel 3110 and is disposed in the first mounting groove of the second frame 2110, the worm tensioning pin 8120 is connected to inner holes at two ends of the worm 8110 through an extrusion process, and the worm tensioning pin 8120 is rotatably connected to the third connecting hole 2002 of the second frame 2110 through a second bearing 8130. Further, an inner hexagonal groove is formed on an end surface of at least one of the worm tensioning pins 8120, and is used for being matched with an inner hexagonal wrench, so that a user can apply an external force conveniently, and when the user changes the direction of the applied external force, so that the rotation direction of the worm 8100 is changed, the rotation direction of the first supporting part 1000 is changed accordingly.

The first elastic element 4100 is disposed in the first inner cavity and extends in a radial direction of the driving part 3000 (i.e., the first direction). The first elastic member 4100 is, for example, a spring, one end of which is connected to the end of the first housing 1200 away from the driving part 3000 via a fixing shaft 4001, and the other end of which is connected to the first locking member 4200, and in the initial state, the length of the first elastic member 4100 is longer than the original length (i.e. the first elastic member 4100 is in a stretched state), so that the force transmission cable 4320 is always in a tight state.

The first locking member 4200 includes a sleeve 4210, a third elastic member 4220 and a thimble 4230. The sleeve 4210 is arranged perpendicular to the first elastic member 4100 (i.e. the extending direction of the sleeve 4210 is a fourth direction perpendicular to the third direction), and the sleeve 4210 is connected to the other end of the first elastic member 4100. The sleeve 4210 has a second inner cavity extending therethrough in a length direction (i.e., a fourth direction) thereof. The third elastic member 4220 is, for example, a spring, and is disposed in the second inner cavity. The number of the ejector pins 4230 is preferably two, and the two ejector pins 4230 are respectively disposed at two opposite ends of the sleeve 4210 and connected to the third elastic member 4220. When the thimble 4230 is aligned with the locking hole 1001 and the thimble 4230 is not subjected to an external force, the thimble 4230 passes through the locking hole 1001 after passing through the guide sliding groove 1210 to achieve the connection between the first locking member 4200 and the first supporting portion 1000, and when the thimble 4230 is subjected to an external force and the third elastic member 4220 is compressed, the thimble 4230 moves in a direction away from the locking hole 1001 (i.e. in a direction close to the guide sliding groove 1210) and is separated from the locking hole 1001, so that the first locking member 4200 cannot be connected with the first supporting portion 1000. Preferably, the first locking member 4200 further comprises two screw caps 4240, each screw cap 4240 is sleeved on one end of the sleeve 4210 and guides and limits the movement of the thimble 4230.

The second elastic member 4310 is, for example, a spring, and the number thereof is at least two. The force transfer cable 4320 includes a first positioning shaft 4321, a second positioning shaft 4322, and a cable body 4323. The first positioning shaft 4321 is connected to at least two ends of the second elastic members 4310 away from the first locking member 4200. The second positioning shaft 4322 is connected to the driving portion 3000, for example, a second mounting groove 3121 is formed on the transmission disc 3120 of the driving portion 3000, and the second positioning shaft 4322 is mounted in the second mounting groove 3121. One end of the cable body 4323 is connected to the first positioning shaft 4321, and the other end is connected to the second positioning shaft 4322. Further, a first positioning groove (not labeled in the figure) extending around the axis of the first positioning shaft 4321 for one circle is formed in the middle of the first positioning shaft 4321, a second positioning groove (not labeled in the figure) extending around the axis of the second positioning shaft 4322 for one circle is formed in the middle of the second positioning shaft 4322, the cable body 4323 is of an annular structure, one end of the cable body is sleeved in the first positioning groove of the first positioning shaft 4321, and the other end of the cable body is sleeved in the second positioning groove of the second positioning shaft 4322, so as to prevent displacement, reduce contact between different areas of the cable body 4323 itself, and further reduce friction.

It will be understood by those skilled in the art that when the tissue adjusting device is in the initial state, the cable body 4323 extends along the radial direction of the driving portion 3000, but when the other end of the force transmission cable 4320 (i.e. the second positioning shaft 4322) is driven by the driving portion 3000 to rotate around the rotation axis, the rotation of the first supporting portion 1000 is delayed due to the blocking effect of the first elastic element 4100 or the second elastic element 4310, so that the cable body 4323 no longer extends along the radial direction of the driving portion 3000, and the cable body 4323 contacts with the first frame body 1110 and generates sliding friction, which is prone to wear. To solve this problem, the tissue adjusting device further includes at least one rotating shaft set, and the rotating shaft set is connected to the first supporting portion 1000, and particularly can be connected to the first frame body 1110 through a threaded shaft 1004, so that the rotating shaft set is located between the second elastic body 4310 and the driving portion 3000. The rotating shaft group comprises two rotating shafts, the two rotating shafts are arranged in parallel, and the axes of the rotating shafts are parallel to the rotating axis. The cable body 4323 passes through a gap between the two rotation shafts. The cable body 4323 contacts with the surface of the rotation shaft and drives the rotation shaft to rotate during the movement process, so that the cable body 4323 generates rolling friction which is smaller than sliding friction generated when the cable body 4323 contacts with the first frame body 1110, and the service life of the cable body 4323 is prolonged. The rotation shaft may be a third bearing 1005.

The angle indicating mechanism may be disposed on a side of the worm wheel 3110 remote from the transmission plate 3120, and include a dial 9100 and an indicator 9200. The dial 9100 is coupled to the first frame body 1110 of the first support part 1000 to be rotated about the rotation axis in synchronization with the first support part 1000. The calibrated scale 9100 further has a fourth connecting hole 9101, preferably fourth connecting hole 9101 department is provided with fourth bearing 9102, fourth bearing 9102 suit is in on the center pin 3200. The indicator 9200 is connected to the second frame 2110 of the second supporting portion 2000 and is kept stationary relative to the second frame 2110. A fifth connection hole 9201 through which the center shaft 3200 passes is further formed in the indicator 9200, and the indicator 9200 is located on a side of the scale 9100, which is far from the worm wheel 3110.

Preferably, the tissue adjusting device further comprises a second clamping ring 6002, wherein the second clamping ring 6002 is connected to the central shaft 3200, is located at a side of the indicator 9200 away from the dial 9100, and is used for preventing the indicator 9200 and the dial 9100 from being separated from the central shaft 3200.

In addition, a plurality of first linkages 1201 are provided on the first housing 1200 of the first support 1000 at intervals in a length direction thereof (i.e., the first direction), and the first wrapping tape 5100 is used to selectively connect with at least one of the first linkages 1201 to adjust a position of the first wrapping tape 5100 on the first support 1000. And a plurality of second connecting mechanisms 2201 extending along the length direction of the second housing 2200 of the second support part 2000 are provided, and the second wrapping belt 5200 is used for selectively connecting with at least one second connecting mechanism 2201 to adjust the position of the second wrapping belt 5200 on the second support part 2000. The first and

second wrapping bands

5100 and 5200 may be attached to the respective support portions by any suitable means, such as screws, rivets, etc. For example, when the first connecting mechanism 1201 and the second connecting mechanism 2201 are both second insert nuts, the first wrapping band 5100 and the second wrapping band 5200 are both provided with counter bores matched with the first wrapping band and the second wrapping band 5200. In this embodiment, the first wrapping band 5100 and the second wrapping band 5200 are made of elastic materials, so as to be conveniently wrapped on the thigh or the lower leg of the patient in a fitting manner, and the first wrapping band 5100 and the second wrapping band 5200 are both provided with connecting through holes for allowing a magic tape and/or a bandage to pass through and fixing the corresponding wrapping bands on the body of the patient.

The following describes a preferred method of use for rehabilitation training of the knee joint using the tissue conditioning device.

Firstly, the included angle between the first supporting part 1000 and the second supporting part 2000 is adjusted according to the actual condition of the knee joint of the patient: an external force is applied to the thimble 4230 of the first locking member 4200 to disengage the thimble 4230 from the locking hole 1001, the first locking member 4200 is disconnected from the first supporting portion 1000, and then an external force is applied to the worm 8100 by using an allen wrench to rotate the first supporting portion 1000 around the rotation axis in the first direction via the driving portion 3000 and the force transmitting portion, or an external force is directly applied to the first supporting portion 1000 to rotate the first supporting portion 1000 around the rotation axis in the first direction until the included angle between the first supporting portion 1000 and the second supporting portion 2000 is at a proper angle. Before the angle between the first supporting portion 1000 and the second supporting portion 2000 reaches a proper value, a user needs to apply an external force to the thimble 4230 to keep the first supporting portion 1000 and the first locking member 4200 in an unconnected state every time the thimble 4230 of the first locking member 4200 passes through one of the locking holes 1001. When the angle is proper, the user no longer applies external force to the thimble 4230, so that the thimble 4230 passes through the corresponding locking hole 1001, the first supporting part 1000 and the first locking member 4200 are connected, and the relative position of the first supporting part 1000 and the second supporting part 2000 is maintained.

The patient then wears the tissue conditioning device, i.e. the first support 1000 is connected to the lower leg of the patient by the first wrapping band 5100 and the second support 2000 is connected to the upper leg of the patient by the second wrapping band 5200.

Next, the user applies an external force to the worm 8100 by using an allen wrench to drive the first supporting portion 1000 to rotate around the rotation axis along the first direction, so as to drive the lower leg of the patient to rotate for a flexion motion, and meanwhile, the second elastic member 4210 stores elastic potential energy.

Then, the external force applied to the worm 8100 is stopped, so that the second elastic member 4210 releases elastic potential energy, and the first supporting portion 1000 is driven to rotate around the rotation axis along the first direction, thereby driving the lower leg of the patient to rotate to continue the flexion motion. As can be understood by those skilled in the art, when the second elastic member 4210 releases the elastic potential energy to drive the first supporting portion 1000 to rotate, the force applied to the first supporting portion 1000 is a dynamically changing force.

Alternatively, when an external force is applied to the worm 8100 using the allen key to rotate the first support 1000 about the second direction after the patient wears the tissue adjusting device, the knee joint may be extended.

Alternatively, after the patient wears the tissue adjusting device, a screw is screwed into the first insert nut 7100 of the cover 1120 and pressed against the driving plate 3120 to lock the first supporting part 1000 and the driving part 3000. Then, an external force is applied to the worm 8100 by using an allen wrench, so that the driving portion 3000 rotates along the first direction, and the first supporting portion 1000 is directly driven to rotate, so as to drive the lower leg of the patient to rotate.

Although the present invention is disclosed above, it is not limited thereto. Various modifications and alterations of this invention may be made by those skilled in the art without departing from the spirit and scope of this invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
