Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to an electric Taylor stent. Background Technology

[0002] The Taylor frame is an important tool for treating complex fractures, nonunion, and deformity correction. Its basic principle involves implanting Kirschner wires or semi-circular wires into the bone, connecting them to a circular or semi-circular Taylor frame. By precisely adjusting the length of the connecting rods, precise control of the bone segment's spatial six degrees of freedom is achieved, thereby gradually reducing the fracture or correcting the deformity.

[0003] In existing technologies, when adjusting traditional Taylor stents or similar multi-bar spatial stents, doctors must manually adjust the mechanical length of each of the six connecting rods according to a pre-set treatment plan. However, each adjustment of the connecting rods requires measurement, calculation, and manual locking, making the operation extremely cumbersome and prolonging the operation time. Furthermore, the adjustment accuracy is highly dependent on the doctor's experience and feel, and human error can easily affect the final repositioning effect.

[0004] In recent years, motorized Taylor stents have emerged. These stents use motors to drive connecting rods, enabling length adjustment for automated, high-precision repositioning, simplifying operation and improving accuracy. However, each connecting rod requires a motor, resulting in high costs for motorized Taylor stents. Furthermore, during the long postoperative fixation and healing period, patients need to wear the motorized Taylor stent long-term, and the large size and weight of the motor cause significant burden and discomfort in daily life. The complex electronic system is constantly exposed to the external environment, posing risks of malfunction, fluid ingress, and electromagnetic interference. Frequent motor charging or battery replacements also increase the hassle of use and maintenance. Summary of the Invention

[0005] The purpose of this invention is to provide an electrically driven Taylor stent. This stent can adjust the length of the Taylor rod through a drive mechanism during the critical repositioning phase of surgery, achieving rapid, precise, and controllable adjustment to improve surgical efficiency and effectiveness. After repositioning is completed and the patient enters the long-term fixation phase, the drive mechanism can be disassembled, allowing the patient to wear a lightweight and robust purely mechanical stent. The disassembled drive mechanism can be reused, thereby significantly reducing costs, alleviating the burden on patients, facilitating maintenance, and improving the overall reliability of the system while ensuring treatment effectiveness.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 7 As shown, this embodiment provides an electric Taylor bracket, which includes a Taylor ring frame 1, a drive mechanism 2, and a control module. The Taylor ring frame 1 includes a proximal ring 11, a distal ring 12, several adjustable-length Taylor rods 13, several universal joints 14, and several connecting shafts 15. Both ends of the Taylor rods 13 are connected to universal joints 14. Each connecting shaft 15 corresponds to and is connected to a universal joint 14. The connecting shafts 15 at the first end of each Taylor rod 13 are connected to the proximal ring 11, and the connecting shafts 15 at the second end of each Taylor rod 13 are connected to the distal ring 12. The drive mechanism 2 can drive the connecting shafts 15 connected to one side of the proximal ring 11. The drive mechanism 2 can drive the Taylor rods 13 to achieve length adjustment. The drive mechanism 2 is detachably connected to the connecting shafts 15 and is communicatively connected to the control module.

[0024] During the critical reduction phase of the surgery, the Taylor ring frame 1 is installed as a whole on the patient's site requiring correction. The drive mechanism 2 is connected to the connecting shaft 15 located on one side of the proximal ring 11. The drive mechanism 2 drives the Taylor rod 13 to adjust its length for correction. The drive mechanism 2 enables rapid, precise, and controllable adjustment of the Taylor rod 13, improving surgical efficiency and effectiveness. After the reduction surgery is completed and the patient enters the long-term fixation phase, the drive mechanism 2 is disassembled, allowing the patient to wear a lightweight and robust purely mechanical frame, improving patient comfort. The disassembled drive mechanism 2 can be reused, thus significantly reducing costs and alleviating the burden on patients while ensuring treatment effectiveness. Simultaneously, it avoids the risk of malfunction, fluid ingress, and electromagnetic interference from long-term exposure of the electronic system to the external environment, improving the overall reliability of the electric Taylor frame and eliminating the need to charge or replace the battery in the drive mechanism 2, simplifying maintenance. If minor adjustments to the length of the Taylor rod 13 are required during the critical reduction phase of the surgery, a special wrench or other manual tool can be used to adjust the connecting shaft 15 for minor adjustments. In addition, the drive mechanism 2 can adjust the length of all Taylor rods 13 with only one installation and removal, which is convenient for doctors to operate and further improves surgical efficiency.

[0025] Specifically, both the proximal ring 11 and the distal ring 12 are made of metal. The proximal ring 11 and the distal ring 12 can be circular, semi-circular, or U-shaped, etc. In this embodiment, both the proximal ring 11 and the distal ring 12 are circular. Both the proximal ring 11 and the distal ring 12 have several circular holes for easy installation and fixing of other components. Six Taylor rods 13 are provided, and twelve universal joints 14 and connecting shafts 15 are provided. Both ends of the Taylor rods 13 are connected to the corresponding connecting shafts 15 via universal joints 14. The six Taylor rods 13 are arranged circumferentially around the proximal ring 11, and adjacent Taylor rods 13 are inclined in opposite directions. The connecting shafts 15 are respectively fixed to the corresponding proximal ring 11 or distal ring 12 with bolts. The control module is installed on the drive mechanism 2, improving the integration of the electric Taylor bracket and making the overall structure of the electric Taylor bracket more compact.

[0026] Optionally, see Figure 2 and Figure 3 The Taylor rod 13 includes a threaded rod 131 and a threaded sleeve 132. The threaded rod 131 and the threaded sleeve 132 are threadedly connected, and both the threaded rod 131 and the threaded sleeve 132 are connected to a universal joint 14. Rotating the threaded rod 131 or the threaded sleeve 132 allows for length adjustment of the Taylor rod 13. Due to the inherent self-locking characteristic of the threaded structure, the length of the Taylor rod 13 is firmly locked after adjustment, preventing changes in the length of the Taylor rod 13 during long-term fixed periods. Specifically, the connecting shaft 15 connected to the threaded rod 131 is used to connect the proximal ring 11, and the connecting shaft 15 connected to the threaded sleeve 132 is used to connect the distal ring 12.

[0027] Optionally, see Figure 3 and Figure 4 The Taylor ring frame 1 also includes a connector 16 connected to the distal ring 12. A first engaging portion 151 is provided on the connecting shaft 15 located at the second end of the Taylor rod 13, and a second engaging portion 161 is provided on the connector 16. The first engaging portion 151 engages with the second engaging portion 161. By engaging the first engaging portion 151 with the second engaging portion 161, when the threaded rod 131 rotates, the rotation of the threaded sleeve 132 can be prevented from causing the length of the Taylor rod 13 to be unadjustable. Specifically, the first engaging portion 151 is an engaging protrusion, which is encircled on the outer wall of the connecting shaft 15. The second engaging portion 161 is an engaging hole, and the inner wall of the engaging hole is provided with a groove corresponding to the engaging protrusion. The connecting shaft 15 extends into the engaging hole and engages the engaging protrusion in the groove. In other embodiments, the cross-section of the first engaging portion 151 can be square, and the engaging hole can be a square hole, with the first engaging portion 151 engaging in the square hole.

[0028] Furthermore, several connectors 16 are provided, each with two second locking portions 161. The connecting shafts 15 on two adjacent Taylor rods 13 are connected to the same connector 16. By connecting the connecting shafts 15 on two Taylor rods 13 to the same connector 16, rotation of the connector 16 can be prevented, further preventing rotation of the threaded sleeve 132. Specifically, three connectors 16 are provided. A fixing hole 162 is provided at the center of the connector 16, through which bolts are passed to fix the connector 16 to the distal ring 12. The two second locking portions 161 are located on both sides of the fixing hole 162 and are symmetrically arranged about the center of the fixing hole 162.

[0029] Optionally, see Figure 2 The Taylor ring holder 1 also includes Kirschner wire clips 17, which are connected to the proximal ring 11 or the distal ring 12 and are used to fix Kirschner wires. Specifically, the Kirschner wire clips 17 are installed in the circular holes on the proximal ring 11 or the distal ring 12. The number of Kirschner wire clips 17 is determined according to specific circumstances, and this embodiment does not limit this. Kirschner wire clips 17 are mature technology in the field, and this application will not elaborate on them.

[0030] Optionally, see Figure 2 The Taylor ring frame 1 also includes a Steinmann pin clip 18, which is connected to the proximal ring 11 or the distal ring 12 and is used to fix the Steinmann pin. Specifically, the Steinmann pin clip 18 is installed in a circular hole on the proximal ring 11 or the distal ring 12. The number of Steinmann pin clips 18 is determined according to specific circumstances, and this embodiment does not limit this. The Steinmann pin clip 18 is a mature technology in the field, and this application will not elaborate on it.

[0031] Optionally, see Figure 3The Taylor ring frame 1 also includes several markers 19, each corresponding to and connected to a Taylor rod 13. The control module can identify the markers 19 to determine the corresponding Taylor rod 13, thereby adjusting each Taylor rod 13 to a different length. Specifically, six markers 19 are provided. The six markers 19 are marker rings of different colors, fitted onto the threaded rod 131. In other embodiments, the markers 19 can also be magnetic induction sheets with different numbers.

[0032] Optionally, see Figure 3 The Taylor rod 13 has a scale line 133 on its outer wall. This scale line 133 facilitates observation of the adjustable length of the Taylor rod 13 to confirm whether its length meets the expected requirements. Specifically, the threaded sleeve 132 has an axially extending oblong hole 1321, and the edge of the oblong hole 1321 has the scale line 133. An indicator block 1311 for indicating the scale line 133 is rotatably connected to the end of the threaded rod 131 away from the universal joint 14. The indicator block 1311 is slidably connected within the oblong hole 1321, allowing it to indicate the position of the threaded rod 131 while also limiting the length adjustment range of the Taylor rod 13.

[0033] Optionally, see Figures 5-7 The drive mechanism 2 includes a mounting plate 21, a circuit board assembly, and several motors 22. Each motor 22 corresponds to and is driven by a Taylor lever 13. All motors 22 are electrically connected to the circuit board assembly, which is communicatively connected to the control module. The circuit board assembly and all motors 22 are mounted on the mounting plate 21. This arrangement integrates the circuit board assembly and motors 22 onto the mounting plate 21, facilitating the simultaneous installation and removal of all motors 22 and all connecting shafts 15, thus improving installation and removal efficiency. Furthermore, each Taylor lever 13 can be individually adjusted in length using a separate motor 22.

[0034] Specifically, the mounting plate 21 is a partial annulus, and its diameter is the same as that of the proximal ring 11 and the distal ring 12. Six motors 22 are provided. The six motors 22 are fixed to the same side of the mounting plate 21 by screws, and the output shafts of all six motors 22 extend to the other side of the mounting plate 21, with their positions corresponding to the connecting shaft 15. A connector 27 is fixedly connected to the output shaft by screws. The side of the connector 27 facing away from the mounting plate 21 has a connecting groove 271 that mates with the connecting shaft 15 connected to the threaded rod 131. The connecting shaft 15 can be inserted into the connecting groove 271. The motors 22 drive the output shaft to rotate, thereby rotating the connector 27, and consequently, rotating the connecting shaft 15.

[0035] Optionally, the circuit board assembly includes a main circuit board 26 and several sub-circuit boards 23. Each sub-circuit board 23 is connected to a motor 22 in a one-to-one correspondence. All sub-circuit boards 23 are electrically connected to the main circuit board 26, and the main circuit board 26 is communicatively connected to the control module. This configuration facilitates individual control of each motor 22, provides greater flexibility in the installation positions of the sub-circuit boards 23 and the main circuit board 26, and simplifies the manufacturing of the circuit board assembly. Specifically, six sub-circuit boards 23 are provided, and all six sub-circuit boards 23 and the main circuit board 26 are fixed to the mounting plate 21 with screws.

[0036] Optionally, the drive mechanism 2 further includes a locking member 24, which is mounted on the mounting plate 21 and is detachably connected to the proximal ring 11. The locking member 24 secures the drive mechanism 2 to the proximal ring 11, improving the stability of the connection between the drive mechanism 2 and the connecting shaft 15. Simultaneously, the detachable connection of the locking member 24 to the proximal ring 11 facilitates its installation and removal. Specifically, the locking member 24 is an electric latch. The proximal ring 11 has a corresponding insertion hole 111. Pressing the button on the electric latch allows it to be inserted into the insertion hole 111, thus securing the mounting plate 21 to the proximal ring 11. The electric latch is a mature technology in the field and will not be described in detail here. In other embodiments, the locking member 24 may also be an electromagnetic lock.

[0037] Optionally, the drive mechanism 2 also includes a housing 25, which, together with the mounting plate 21, forms an installation space where the circuit board assembly and several motors 22 are housed. By providing the housing 25, the circuit board assembly and several motors 22 can be protected from contamination or damage; simultaneously, it makes the overall structure of the drive mechanism 2 more aesthetically pleasing. Specifically, the housing 25 and the mounting plate 21 are connected by screws.

[0038] When installing the drive mechanism 2, press the button of the electric plug to insert the electric plug into the socket 111, and insert the six connecting shafts 15 into the corresponding connecting slots 271 respectively; when disassembling the drive mechanism 2, press the button of the electric plug again to separate the electric plug from the socket 111, and then remove the drive mechanism 2 as a whole.
