[0066] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the scheme in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments in this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0067] It should be noted that all directional indications in the embodiments of this patent (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0068] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0069] In addition, the descriptions of "first", "second", etc. in this patent are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other or independent of each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this patent.

[0070] The traditional fixed bracket needs to be adjusted manually by the patient every day according to the doctor's electronic prescription. The patient needs to manually adjust the telescopic rod of the fixing device regularly. Whether the patient adjusts it by himself or with the assistance of the patient's relatives, it is inevitable that the patient will come into contact with the injured part. Without the practical operation level of a doctor, if the operator cannot adjust it accurately according to the prescription, it is easy to cause the condition to worsen and increase the safety hazard.

[0071] In view of this, if Figure 1-7As shown, this patent proposes an adjustment device and a ring-type bracket system using the adjustment device to solve the technical problem that after the fixed bracket is installed, the patient needs to adjust the relative position between the fixed brackets regularly according to the doctor's prescription by adjusting the length of the telescopic rod to cooperate with the treatment, which is easy to cause safety hazards.

[0072] The patent is described in detail below in conjunction with the accompanying drawings.

[0073] Implementation Method 1

[0074] The first embodiment of this patent discloses an adjustment device A, see Figure 1 and Figure 2 The adjusting device A is mainly applied to the ring support system B and comprises:

[0075] Mounting member 1, arranged on the ring bracket system B;

[0076] The guide member 2 is connected to the mounting member 1 and has a hollow structure to form a guide channel 21.

[0077] A guide channel 21, which is hollow and connected to the mounting member 1, with one end of the guide channel 21 connected to the mounting member 1;

[0078] An adjusted member 3, wherein at least a portion of the adjusted member 3 extends into the guide channel 21;

[0079] A transmission assembly 4, which is arranged on the mounting member 1 and is in transmission connection with the adjusted member 3;

[0080] The transmission assembly 4 is used to drive the adjusted member 3 to move along the guide channel 21 .

[0081] The adjusting device A of this embodiment is mainly applied to the ring bracket system B, and includes a mounting member 1, a guide member 2, an adjustable member 3 and a transmission assembly 4. In order to enable the adjusting device A to change its own length, the adjusting device A is provided with a guide member 2 and a debugging member. Specifically, the guide member 2 has a hollow structure, which forms a guide channel 21, at least part of the adjustable member 3 extends into the guide channel 21 and forms a match with the guide channel 21, and the adjustable member 3 can move in the guide channel 21 relative to the guide member 2. Further, in order to enable the adjustable member 3 to drive and control its telescopic amount relative to the guide member 2, the transmission assembly 4 is provided in this embodiment to be connected to the adjustable member 3 in a transmission manner. The transmission assembly 4 and the guide member 2 are both mounted on the mounting member 1, and can be set to be fixed relative to the mounting member 1. In this way, the adjustable member 3 can be driven and moved by the debugging assembly relative to the overall adjustment assembly, the mounting member 1 and the guide member 2, so as to achieve the effect of changing the telescopic length of the adjusting device A itself.

[0082] Accordingly, the present embodiment further discloses a ring-type bracket system B, including a universal coupling 110, the ring-type bracket system B includes a first bracket 7, a second bracket 8 and the adjustment device A as described above, and,

[0083] The second end of the adjusted member 3 is connected to the first bracket 7 via a universal coupling 110;

[0084] The second end of the guide member 2 is connected to the second bracket 8 via a universal coupling 110;

[0085] The ring bracket system B can change the distance and angle between the first bracket 7 and the second bracket 8 by the extension length of the adjustable member 3 relative to the guide member 2 .

[0086] The ring bracket system B may include a universal coupling 110, a first bracket 7, a second bracket 8, and the aforementioned ring bracket system B. The universal coupling 110 is a common mechanical connector in the technical field, which is mainly used to transfer rotational motion from one axis to another axis, while allowing these axes to shift, tilt or rotate relative to each other. For example, after the first bracket 7 and the adjustment device A are connected through the universal coupling 110, the adjustment device A can rotate in space at any angle in the space on one side of the first bracket 7 with the universal coupling 110 as the rotation center.

[0087] It is worth noting that the adjusted part 3 has a first end and a second end opposite thereto in orientation. The first end of the adjusted part 3 is an end extending into the guide channel 21 of the guide member 2, and the second end of the adjusted part 3 is the farthest end still remaining outside the guide channel 21. The second end of the adjusted part 3 is used to connect the universal coupling 110.

[0088] Correspondingly, the guide member 2 also has a first end and a second end opposite thereto in orientation. The first end of the guide member 2 is the end that first contacts the first end of the adjusted member 3 during the installation of the adjusted member 3 , and the second end of the guide member 2 is used to connect the universal coupling 110 .

[0089] The second end of the adjusted member 3 of the adjusting device A is connected to the first bracket 7 through the universal coupling 110, and the second end of the guide member 2 of the adjusting device A is connected to the second bracket 8 through the universal coupling 110, and multiple adjusting devices A are arranged between the first bracket 7 and the second bracket 8 to form a ring-type bracket system B. By changing the elongation of the adjusted member 3 relative to the guide member 2 in the multiple adjusting devices A, the relative distance and angle between the first bracket 7 and the second bracket 8 can be changed. Through the ring-type bracket system B arranged as above, the patient can install the ring-type bracket system B on the limb part with lesions or that needs rehabilitation and fixation, input the electronic prescription issued by the doctor, and make it operate automatically and rotate to the predetermined position regularly, so as to achieve the medical effect of postoperative rehabilitation and avoid the safety hazards caused by manual adjustment by the patient.

[0090] Exemplarily, a through slot 22 is provided on the guide member 2, and the through slot 22 is provided along the length direction of the guide channel 21 and connects the guide channel 21 and the external space, and a scale line (not shown) is provided at the portion where the through slot 22 connects with the outer peripheral surface of the guide channel 21; a measuring hole 31 matching the through slot 22 is provided on the adjusted member 3, and the position of the measuring hole 31 relative to the scale line is used to display the extended length of the adjusted member 3 relative to the guide channel 21. By providing the measuring hole 31 on the adjusted member 3 and the scale line on the guide member 2, the amount of movement of the adjusted member 3 relative to the guide member 2 can be clearly measured, so that the operator can check in time whether the adjustment device A is operating normally according to the electronic prescription.

[0091] Implementation Method 2

[0092] This embodiment is a further improvement based on the first embodiment, and its improvement lies in that a better adjustment device A is provided, specifically:

[0093] See also Figure 3 As shown, the regulating device A also includes:

[0094] A driving power source 5, which is mounted on the mounting member 1, and includes an output shaft, and the transmission assembly 4 is connected to the output shaft;

[0095] The driving power source 5 drives the transmission assembly 4 to drive the adjusted component 3 to move along the guide channel 21 .

[0096] Since the ring-type support system B automatically operates according to the electronic prescription, the adjustment device A needs to be provided with a driving power source 5 to support its own movement to drive the ring-type support system B to rotate accordingly. The driving power source 5 is mounted on the mounting member 1, and the driving power source 5 includes an output shaft, and the driving power source 5 is connected to the transmission assembly 4 through the output shaft. In some embodiments, the driving power source 5 can be a motor, and the motor drives the output shaft to rotate to drive the transmission assembly 4 to perform telescopic adjustment on the adjusted member 3, so that the adjusted member 3 can move relative to the mounting member 1 along the guide channel 21.

[0097] Implementation Method 3

[0098] This embodiment is a further improvement based on the first to second embodiments, and the main difference is that in this embodiment, another available structure of the adjustment device A is provided.

[0099] Specifically, see Figure 4 and Figure 6 As shown, the transmission assembly 4 of the regulating device A in this embodiment also includes:

[0100] A first gear member 41, wherein the first gear member 41 defines a threaded through hole 411;

[0101] The adjusted member 3 is a round rod, which passes through the threaded through hole 411. The round rod is provided with a thread 32, and the threaded through hole 411 cooperates with the thread 32 of the round rod.

[0102] When the first gear member 41 is driven to rotate by the driving power source 5 , the round rod is driven by the first gear member 41 to move along the axial direction of the guide channel.

[0103] The transmission assembly 4 of this embodiment includes a first gear member 41, and a threaded through hole 411 is provided on the first gear member 41. The threaded through hole 411 is provided on the rotation axis of the first gear member 41. In this embodiment, the regulated member 3 can be selected as a round rod with a thread 32 provided on the circumferential surface, and the round rod is arranged through the threaded through hole 411 of the first gear member 41, and the thread 32 on the round rod cooperates with the threaded through hole 411 on the first gear member 41, and the first gear member 41 rotates around its own rotation axis to make the round rod move along the guide channel 21. In other words, the first gear member 41 converts its own rotational motion into the axial motion of the round rod through the threaded through hole 411 and the thread 32 on the round rod, and the round rod performs telescopic motion relative to the first gear member 41 in the axial direction. The first gear with the threaded through hole 411 is provided, and the telescopic distance of the round rod can be more accurately regulated by cooperating with the thread 32 of the round rod, thereby improving the accuracy of the regulating device A.

[0104] For example, see Figure 4As shown, in order to transmit the driving force of the driving power source 5 to the first gear member 41, the transmission assembly 4 further includes:

[0105] A second gear member 42, the second gear member 42 is meshed with the first gear member 41, and a shaft hole 421 is formed on the second gear member 42, and the shaft hole 421 is matched with the output shaft;

[0106] The second gear member 42 is mounted on the mounting member 1 and meshes with the first gear member 41. The second gear is provided with an axial hole 421 for cooperating with the output shaft, and the axial hole 421 is provided on the rotation axis of the second gear. By providing the second gear member 42, the driving power source 5 can drive the second gear member 42 connected to the output shaft to rotate around its rotation axis first through the output shaft, and the second gear member 42 drives the first gear member 41 meshed therewith to rotate, and the first gear member 41 further drives the adjusted member 3 to move along its axial direction. The provision of the second gear member 42 is conducive to controlling the movement of the adjusted member 3 by the driving power source 5, and can realize the parallel installation of the driving power source 5 and the adjusted member 3, thereby reducing the volume of the adjusting device A and saving the space occupied by the entire ring-type bracket system B.

[0107] Implementation Method 4

[0108] This embodiment is a further improvement based on any one of the first to third embodiments, and the main improvement is that, in this embodiment, the structure of the adjustment device A is further improved.

[0109] Specifically, see Figure 5 As shown, the mounting member 1 of the adjusting device A in this embodiment further includes:

[0110] A first mounting seat 11, in which the first gear member 41 is mounted;

[0111] The second mounting seat 12 , and the second gear member 42 are mounted in the second mounting seat 12 .

[0112] In order to better maintain the position between the first gear member 41 and the second gear member 42 and protect the first gear member 41 and the second gear member 42 from being disturbed by dust, a first mounting seat 11 that can at least partially accommodate the first gear member 41 and a second mounting seat 12 that can at least partially accommodate the second gear member 42 are provided on the mounting member 1. The first mounting seat 11 and the second mounting seat 12 can be circular hollow structures that match the shapes of the first gear member 41 and the second gear member 42. The provision of the first mounting seat 11 and the second mounting seat 12 as above can keep lubricating equipment such as lubricating oil in the first mounting seat 11 and the second mounting seat 12, reduce the wear of internal components and maintain the stable process operation of the first gear member 41 and the second gear member 42.

[0113] For example, see Figure 5 As shown, the adjusting device A also includes a bearing 6, and,

[0114] The first gear member 41 has a first mounting wall 412 along its axial direction, and the second gear member 42 has a second mounting wall 422 along its axial direction;

[0115] The bearing 6 is installed between the first installation wall 412 and the first installation seat 11 , and between the second installation wall 422 and the second installation seat 12 .

[0116] The adjusting device A may include a bearing 6, and the first gear member 41 includes a gear portion and a first mounting wall 412 extending in the axial direction thereof, and the bearing 6 may be mounted on the first mounting wall 412. The bearing 6 may be mounted between the first mounting wall 412 and the first mounting seat 11 to support the first gear member 41 and reduce the resistance of the first gear member 41 to rotate in the first mounting seat 11. Similarly, the bearing 6 may be mounted between the second mounting wall 422 of the second gear member 42 and the second mounting seat 12 of the mounting member 1 to support the second gear member 42 and reduce the resistance of the second gear member 42 to rotate in the second mounting seat 12.

[0117] For example, see Figure 1 As shown, the adjustment device A also includes an encoder 10, which is connected to the driving power source 5. The encoder 10 can control the number of rotations of the main shaft driven by the driving power source 5, so that the adjustment device A can adjust the telescopic length of the adjusted member 3 relative to the guide member according to the electronic prescription. The encoder 10 can also include a magnetic ring base 101 made of a permanent magnet, which can resist interference and suppress high-frequency signals to protect the normal operation of the encoder 10. In some embodiments, the magnetic ring base 101 can be combined with the encoder 10 to facilitate separate replacement and maintenance to reduce costs.

[0118] Exemplary, combined Figure 3 , Figure 8 and Fig. 9 As shown, the adjusting device A further comprises a fixing member 120 , and the fixing member 120 has an accommodating space 1201 . The fixing member 120 can engage with the mounting member 1 and accommodate the transmission assembly 4 in the accommodating space 1201 .

[0119] The fixing member 120 can be connected to the mounting member 1 by bolts, and the first gear member 41 and the second gear member 42 are accommodated in the accommodating space 1201 to avoid being contaminated by dust and mud during operation.

[0120] Furthermore, the fixing member 120 also has a fixing frame 1202, which is parallel to the axial direction of the driving power source 5 and the guide member 2 and is arranged between the driving power source 5 and the guide member 2. The fixing frame 1202 has fitting grooves 1203 on both sides, and the driving power source 5 and the guide member 2 can be fitted into the fitting grooves 1203 on both sides of the fixing frame 1202 at the same time. A fastener 1204 and / or a fixing seat 1205 are arranged at the end of the fixing frame 1202 to cooperate with the fixing frame 1202 to fix the driving power source 5 and the guide member 2 on the mounting frame.

[0121] It is understandable that one end of the driving power source 5 and the guide member 2 is mounted on the mounting member 1, similar to a cantilever beam structure, and if the other end is not fixed, it will shake. Therefore, by providing the above-mentioned fixing frame 1202, it is possible to prevent the driving power source 5 and the guide member 2 from shaking and causing structural instability.

[0122] It is worth mentioning that due to the large radial dimension, the driving power source 5 can be fastened to the fixing frame 1202 using the fastener 1204, which is convenient for installation. The guide member 2 with a smaller radial dimension can pass through the fixing seat 1205 connected to the fixing member 120, thereby achieving the effect of matching with the fixing member 120.

[0123] Implementation Method 5

[0124] This embodiment is a further improvement based on any one of the first to fourth embodiments, and the main improvement is that, in this embodiment, the structure of the ring support system B is further improved.

[0125] Specifically, see Figure 7 As shown, the ring-type bracket system B of this embodiment further includes a first bracket 7 and a second bracket 8, and the first bracket 7 and the second bracket 8 both include:

[0126] An even number of outer flanges 9 are distributed along the circumferential direction. The outer flanges 9 are provided with mounting holes 91 , and the adjustment device A is mounted on the mounting holes 91 .

[0127] The ring bracket system B may include a first bracket 7 and a second bracket 8. In an optional embodiment, the first bracket 7 and the second bracket 8 may have the same structure to reduce the design and processing cost. The first bracket 7 and the second bracket 8 both have an even number of outer flanges 9, which are arranged around the outer circumference of the first bracket 7 and the second bracket 8, and the outer flanges 9 are provided with mounting holes 91. The adjustment device A may be installed on the mounting holes 91 of the outer flanges 9. Multiple adjustment devices A connect the first bracket 7 and the second bracket 8 by connecting the outer flanges 9.

[0128] For example, Fig.10 and Fig.11As shown in FIG. 1 , the connection surface formed between the axis of the adjusted member 3 of the adjusting device A and the axis of the driving power source 5 is perpendicular to the tangent line of the first bracket 7. In other words, in the process of installing the adjusting device A on the first bracket 7 and finally locking the installation structure, Fig.11 When looking down at the first bracket 7, the length direction of the adjusting device A needs to coincide with the normal direction of the adjusting device A installed at the first bracket 7. The above design can prevent contact and collision between two adjacent adjusting devices A, thus saving limited installation space.

[0129] Exemplary, combined Figure 7 As shown, two adjustment devices A are arranged as a group of adjustment groups, and the second end of the guide member 2 of each group of adjustment devices A is installed on the first bracket 7 with an outer flange 9 spaced apart;

[0130] The second ends of the adjusted parts 3 of each group of adjusting devices A are commonly mounted on the same outer flange 9 of the second bracket 8 .

[0131] The two adjustment devices A are set as one adjustment group, and the second end of the guide member 2 of the adjustment device A in each adjustment group is installed on the outer flange 9 of the first bracket 7, and the second end of the adjusted member 3 of the adjustment device A in each adjustment group is installed on the outer flange 9 of the second bracket 8. Among them, the second end of the guide member 2 of each group of adjustment devices A is installed on the same outer flange 9 on the first bracket 7, and the second end of the adjusted member 3 of each adjustment device A is installed on two outer flanges 9 of the second bracket 8 that are separated by one. In this way, the two adjustment devices A and the second bracket 8 form a triangular structure together, and the two adjacent adjustment devices A of the adjacent adjustment groups and the first bracket 7 together form an inverted triangular structure, which can effectively support the first bracket 7 and the second bracket 8, and prevent the distance and angle between the first bracket 7 and the second bracket 8 from changing too much, which is beneficial to the protection and fixation of the patient's limbs.

[0132] For example, see Figure 7 As shown, the outer flanges 9 of the first bracket 7 and the second bracket 8 are respectively provided in 6 numbers, and the adjustment groups are provided in 3 numbers. The 3 adjustment groups can connect the first bracket 7 and the second bracket 8 in the following manner.

[0133] The first connection method: six outer flanges 9 and three adjustment groups are distributed in a circumferential manner with the common axis of the first bracket 7 and the second bracket 8 as the center, and the spacing between two adjacent adjustment groups is the same to ensure that the first bracket 7 and the second bracket 8 always maintain a horizontal plane during relative movement, avoiding the first bracket 7 and / or the second bracket 8 from tilting, resulting in the movement distance between the two being inconsistent with the doctor's electronic prescription information.

[0134] The second connection mode: three groups of adjustment groups, some of which can be set vertically, and the remaining adjustment groups can be set at an angle, and the tilting modes of the tilted adjustment groups can be inconsistent. With this arrangement, doctors can apply the structure to the scene of deformed bone correction, and adjust the inclination of the first bracket 7 or the second bracket 8 by tilting the adjustment group to match the growth shape of the deformed bone or the correction trajectory.

[0135] In an optional embodiment, a controller is provided on the first bracket 7 or the second bracket 8, and the controller has an emergency stop button. When the ring bracket system B is being debugged, or if a fault occurs during the execution of an electronic prescription by the ring bracket system B, the ring bracket system B can be stopped by triggering the emergency stop button.

[0136] Finally, it should be noted that ordinary technicians in this field can understand that in order to make readers better understand this patent, the implementation methods of this patent propose many technical details. However, even without these technical details and various changes and modifications based on the above-mentioned implementation methods, the technical solutions claimed for protection by the claims of this patent can be basically realized. Therefore, in practical applications, various changes can be made to the above-mentioned implementation methods in form and details without departing from the spirit and scope of this patent.
