[0002] With the changes of the times and society, the spectrum of orthopedic injuries has changed significantly. For example, diseases such as bone and joint tuberculosis, osteomyelitis, and polio have decreased significantly, while trauma caused by traffic accidents has increased significantly. The aging population has led to an increase in fractures and orthopedic joint diseases caused by senile osteoporosis. The influence of environmental factors has led to a corresponding increase in bone tumors and rheumatoid arthritis, etc. In the care of lower limb treatment, a joint limit device is used to fix and treat the joints, and the patient's joints are fixed by using a bracket.

[0003] In clinical work, for patients recovering after lower limb orthopedic surgery, the patients need to use traditional walkers for rehabilitation training of lower limb walking. The healing between bones and joints is not particularly rapid in a short period after surgery, and they are in a normal recovery period. However, in order to prevent the muscles and ligaments between the joints from becoming stiff, patients need to do more exercise rehabilitation. However, when using the existing bone and joint limit devices, it is inconvenient for patients to cancel the restrictions of the two limit plates and perform joint movements by themselves. At the same time, when fixation is required after exercise, it is inconvenient for patients to find the original angles of the two limit plates by themselves, which greatly reduces the practicality of the device. For this reason, an orthopedic care joint limit device is proposed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this technical field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6The orthopedic joint limiting device of this embodiment includes a first limiting plate 1, a second limiting plate 2 and a strap 6 installed on the first limiting plate 1 and the second limiting plate 2. The side wall of the first limiting plate 1 is installed with an adjustment unit 3, and the adjustment unit 3 includes a fixed shaft 31 fixedly connected to the side wall of the first limiting plate 1. An insert 32 is installed in the fixed shaft 31. The second limiting plate 2 is rotatably connected to the outer wall of the fixed shaft 31. The outer wall of the insert 32 is fixedly connected to a fixing sleeve 7. The outer wall of the fixing sleeve 7 is provided with a socket 8. The side wall of the second limiting plate 2 is fixedly installed A limiting unit 4 is provided which is movably connected to the socket 8. The limiting unit 4 includes a limiting sleeve 41 fixedly connected to the side wall of the second limiting plate 2. Both ends of the limiting sleeve 41 are respectively provided with a communicating limiting groove 42 and an installation groove 43. A first threaded ring 46 is fixedly connected in the installation groove 43. An insertion rod 44 is passed through the limiting groove 42 and the first threaded ring 46. The outer wall of the insertion rod 44 is fixedly connected to the first threaded ring 46 which is threadedly connected to a threaded block 47. One end of the insertion rod 44 is movably connected to the socket 8, and the other end of the insertion rod 44 is fixedly connected to a screw head 45.

[0025] like Figure 1 、 2 As shown in Figure 5, the joint limit device structure in the present invention is similar to the existing joint limit device structure. The main improvement of the present invention is to facilitate the adjustment of the joint limit device so as to facilitate the patient's exercise recovery. When the joint limit device is used to fix the patient's lower limb joint, the straps 6 on the first limit plate 1 and the second limit plate 2 are tied to the outside of the two joints respectively, and the screw head 45 is moved and rotated. The screw head 45 drives the insertion rod 44 to move and rotate, so that the threaded block 47 on the outer wall of the insertion rod 44 is screwed into the first threaded ring 46, and then the insertion rod 44 is inserted into the insertion hole 8 on the outer wall of the fixing sleeve 7. The mutual restriction of the insertion rod 44 and the fixing sleeve 7 is utilized to prevent the first limit plate 1 and the second limit plate 2 from rotating. When the patient needs to perform exercise rehabilitation on the joint, the screw head 45 can be rotated to move the threaded block 47 out of the first threaded ring 46, and the screw head 45 can be pulled outward to move the insertion rod 44 out of the socket 8. At this time, the restriction on the first limiting plate 1 and the second limiting plate 2 is cancelled, so that the second limiting plate 2 can be rotated on the outer wall of the fixed shaft 31 to make the joint move and then perform rehabilitation exercise. The lower limb joint can be fixed and restored, and the fixation can also be cancelled to perform exercise rehabilitation on the joint. After each release of the joint limiting device, the first limiting plate 1 and the second limiting plate 2 can be rotated to the original angle for fixation through the cooperation of the insertion rod 44 and the socket 8. No offset will be generated, thereby improving practicality.

[0026] like Figure 2-4When the bolt 34 is tightened, the rod 44 is restricted to the insertion hole 8, and the angle between the first limiting plate 2 and the second limiting plate 2 is adjusted.

[0027] like Figure 2-4 As shown, the adjustment unit 3 also includes a tooth groove 35 provided on the inner wall of the fixed shaft 31 and a clearance groove 36 connected to the tooth groove 35. The lower end of the insert tube 32 is fixedly connected to the gear ring 33. One end of the bolt 34 passes through the gear ring 33. The gear ring 33 is movably plugged into the tooth groove 35. The gear ring 33 is slidably connected between the tooth groove 35 and the clearance groove 36. When adjusting the angle of the jack 8, the bolt 34 is first loosened, and then the insert tube 32 is pulled outward. The insert tube 32 drives the gear ring 33 to move from the tooth groove 35 to the clearance groove 36. The clearance groove 36 restricts the gear ring 33 so that the gear ring 33 cannot be pulled out from the fixed shaft 31. At this time, The fixing sleeve 7 is rotated to adjust the angle of the insertion hole 8. The fixing sleeve 7 drives the gear ring 33 to rotate in the give way groove 36 through the insertion tube 32. When the angle of the insertion hole 8 is adjusted, the fixing sleeve 7 is pushed back. During the pushing back process, the fixing sleeve 7 is slightly rotated back and forth so that the fixing sleeve 7 drives the gear ring 33 to be reinserted into the tooth groove 35 through the insertion tube 32. Then the bolt 34 is tightened. The tooth groove 35 restricts the insertion tube 32 through the gear ring 33, and the bolt 34 restricts the insertion tube 32, so that the fixing sleeve 7 does not rotate, so that the restriction between the first limit plate 1 and the second limit plate 2 is firm and will not be loose, thereby improving stability.

[0028] like Figure 5 、 6As shown, the limiting unit 4 also includes a limiting plate 48 rotatably mounted on the outer wall of the insertion rod 44, the limiting plate 48 is slidably connected to the inner wall of the limiting groove 42, and the outer wall of the insertion rod 44 is sleeved with a spring 49, the two ends of the spring 49 are respectively against the side wall of the limiting plate 48 and the inner wall of the limiting groove 42; after the insertion rod 44 is moved to the outside of the insertion hole 8, the threaded block 47 is located in the mounting groove 43, and under the elastic force of the spring 49, the limiting plate 48 is cooperated with the insertion rod 44 to always have an outward moving force, so that when the insertion rod 44 needs to be inserted When inserting into the socket 8, the patient only needs to rotate the joint, and then under the elastic force of the spring 49, the insertion rod 44 is pressed against the outer wall of the fixing sleeve 7 until the socket 8 is rotated to correspond to the insertion rod 44, and then the insertion rod 44 can be inserted into the socket 8. At this time, the screw head 45 is rotated again to make the threaded block 47 and the first threaded ring 46 threadedly connected, thereby restricting the insertion rod 44 in the socket 8 and preventing it from falling off, making it convenient for the patient to restrict and release the first limit plate 1 and the second limit plate 2 by himself, thereby improving practicality.

[0029] like Figure 6 As shown, the limiting unit 4 also includes a second threaded ring 411 fixedly mounted on the inner wall of the mounting groove 43, the threaded block 47 is threadedly connected to the second threaded ring 411, and the first threaded ring 46 and the second threaded ring 411 are respectively located at both ends of the inner wall of the mounting groove 43; when the patient's joint needs to move, the screw head 45 is rotated to separate the threaded block 47 from the first threaded ring 46. At this time, the threaded block 47 is located between the first threaded ring 46 and the second threaded ring 411, and the screw head 45 is pulled outward so that the screw head 45 drives the threaded block 47 to contact and threadably connect with the second threaded ring 411 through the insertion rod 44, thereby tightening the insertion rod 44. The rod 44 is restricted so that it does not contact the fixing sleeve 7, so as to avoid the rod 44 from being inserted into the socket 8 and affecting the movement when the patient's joint moves. At the same time, when it is necessary to insert the rod 44 into the socket 8, it is only necessary to separate the threaded block 47 from the second threaded ring 411. At this time, under the action of the spring 49, the rod 44 is against the outer wall of the fixing sleeve 7, and the joint is rotated to rotate the fixing sleeve 7, thereby inserting the rod 44 into the socket 8, and then the threaded block 47 is threadedly connected to the first threaded ring 46. It is convenient to use. When the patient performs joint rehabilitation exercises, the rod 44 will not be inserted into the socket 8 and cause any influence, thereby improving practicality.

[0030] like Figure 6As shown, the inner wall of the limit groove 42 is fixedly connected with a plurality of limit bars 410, and the limit plate 48 is slidably connected to the outer wall of the limit bar 410, and the limit bar 410 limits the limit plate 48; the limit bar 410 limits the limit plate 48, so that the limit plate 48 will not rotate in the limit groove 42. When the insertion rod 44 moves, it drives the limit plate 48 to move on the outer wall of the limit bar 410 and the inner wall of the limit groove 42. When the insertion rod 44 rotates, the insertion rod 44 and the inner wall of the limit plate 48 rotate, thereby avoiding the elastic force exerted on the limit plate 48 by the spring 49, resulting in greater damping and wear when the rotation of the insertion rod 44 drives the limit plate 48 to rotate, thereby improving practicality.

[0031] like Figure 2 As shown, a silicone pad 5 is fixedly installed on the side of the first limiting plate 1 away from the second limiting plate 2. When the straps 6 on the first limiting plate 1 and the second limiting plate 2 are tied to the two joints of the patient, the silicone pad 5 contacts the skin at the connection between the two joints of the patient's lower limbs, thereby improving the wearing comfort.

[0032] The implementation steps in this embodiment are as follows: when using the joint limiting device to fix the patient's lower limb joints, the straps 6 on the first limiting plate 1 and the second limiting plate 2 are tied to the outside of the two joints respectively, and the silicone pad 5 is in contact with the skin at the connection of the two joints of the patient's lower limbs. At this time, the bolt 34 is loosened, and the cannula 32 is pulled outward. The cannula 32 drives the gear ring 33 to move from the tooth groove 35 to the clearance groove 36. The clearance groove 36 restricts the gear ring 33 so that the gear ring 33 cannot be pulled out from the fixed shaft 31. At this time, the patient can rotate the joint. When the joint is rotated to the angle to be fixed, After the angle of the jack 8 is adjusted, the fixing sleeve 7 is rotated to adjust the angle of the jack 8 so that the jack 8 corresponds to the insertion rod 44. The fixing sleeve 7 drives the gear ring 33 to rotate in the give way groove 36 through the insertion tube 32. When the angle of the jack 8 is adjusted, the fixing sleeve 7 is pushed back. During the pushing back process, the fixing sleeve 7 is slightly rotated back and forth so that the fixing sleeve 7 drives the gear ring 33 to be reinserted into the tooth groove 35 through the insertion tube 32. Then, the bolt 34 is tightened. The tooth groove 35 restricts the insertion tube 32 through the gear ring 33, and the bolt 34 restricts the insertion tube 32, so that the fixing sleeve 7 does not rotate. , at this time, move and rotate the screw head 45, so that the insertion rod 44 is inserted into the insertion hole 8, and the threaded block 47 on the outer wall of the insertion rod 44 is threadedly connected with the first threaded ring 46, the insertion rod 44 is restricted, and the insertion rod 44 cooperates with the insertion hole 8 to prevent the first limit plate 1 and the second limit plate 2 from rotating to protect the joint; when the patient needs to perform rehabilitation exercises on the joint, rotate the screw head 45 to separate the threaded block 47 from the first threaded ring 46, at this time the threaded block 47 is located between the first threaded ring 46 and the second threaded ring 411, and then pull the screw head 45 outward so that the screw head 45 passes through the insertion rod 44 with The movable thread block 47 contacts and is threadedly connected to the second threaded ring 411, thereby restricting the insertion rod 44 so that the insertion rod 44 does not contact the fixed sleeve 7, thereby preventing the insertion rod 44 from affecting the movement when the patient's joint moves. At the same time, when it is necessary to insert the insertion rod 44 into the socket 8, it is only necessary to separate the thread block 47 from the second threaded ring 411. At this time, under the action of the spring 49, the insertion rod 44 is against the outer wall of the fixed sleeve 7, and the joint is rotated to rotate the fixed sleeve 7, thereby inserting the insertion rod 44 into the socket 8, and then the thread block 47 is threadedly connected to the first threaded ring 46.

[0033] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
