Description

Technical Field

[0001] This utility model relates to the field of surgical instruments, specifically a positioning device for orthopedic surgery. Background Technology

[0002] Surgical locators in orthopedic surgery play a crucial role. They primarily provide surgeons with precise positioning and guidance during the procedure. In orthopedic surgery, the position and shape of bones are complex and varied, and the surgical procedures demand extremely high precision. Through specific structures and designs, locators help surgeons accurately determine the surgical site, angle, and depth. In fracture fixation surgery, they assist instruments such as drills in precisely locating the medullary tract, ensuring accurate insertion of screws and other fixation devices, effectively improving surgical precision and success rates, and reducing surgical risks and complications.

[0003] In actual orthopedic surgery, existing positioning devices have revealed many problems that urgently need to be solved. Among them, the limited adjustment angle is particularly prominent. When faced with the diverse bone morphologies of different patients and the complex and ever-changing surgical scenarios, the limited adjustment angle makes it difficult for the positioning device to be accurately adapted, failing to provide the surgeon with the ideal positioning effect, increasing the difficulty and risk of the surgery. In addition, it cannot be adjusted and fixed in segments, which means that during the operation, it is impossible to flexibly and accurately fix the positioning device according to the specific steps and positional requirements. There is still room for improvement in its structure. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for orthopedic surgery, comprising a positioning bracket, wherein a fixed drill bit is slidably connected to the front side of the top end of the positioning bracket, the positioning bracket comprising a single set of positioning rods, wherein multiple sets of the single set of positioning rods are provided, one end of each set of the single set of positioning rods is fixedly connected to a threaded end, and the other end of each set of the single set of positioning rods is provided with a corresponding threaded groove, and the multiple sets of the single set of positioning rods are combined and connected through their respective threaded ends.

[0005] Preferably, the top of the other end of the single positioning rod has a through threaded opening, and a first limiting bolt is threadedly connected inside the opening.

[0016] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0017] Please see Figures 1 to 3 This utility model provides a technical solution: a positioning device for orthopedic surgery, including a positioning bracket 1, a fixed drill bit 2 slidably connected to the front side of the top end of the positioning bracket 1, the positioning bracket 1 including a single set of positioning rods 11, the single set of positioning rods 11 is provided in multiple sets, one end of each single set of positioning rods 11 is fixedly connected to a threaded end 12, the other end of each single set of positioning rods 11 is provided with a corresponding threaded groove, and the multiple sets of single set of positioning rods 11 are combined and connected through their respective threaded ends 12;

[0018] The positioning bracket 1 of this orthopedic surgical locator has excellent segmented multi-angle rotation performance. During the operation, it can flexibly and freely rotate and adjust in multiple directions according to the specific shape, position and angle of the fractured bone, so as to accurately adapt to the fractured bone in different situations and provide great convenience for subsequent fixation operations. At the same time, the fixation drill 2 is also ingeniously designed. Its ball head structure gives it the ability to rotate freely. Combined with its own telescopic characteristics, it can accurately insert and fix the medullary tract according to the predetermined trajectory during the operation, effectively improving the accuracy and success rate of the operation and providing a strong guarantee for the efficient performance of orthopedic surgery.

[0019] The top of the other end of the single positioning rod 11 has a through threaded opening, and the first limiting bolt 13 is threadedly connected inside the opening. A fixing member 14 is fixedly connected to the outer wall of the middle section of the single positioning rod 11. A positioning member 15 is fixedly connected to one side of the fixing member 14. The positioning member 15 is a two-section segmented design and is threadedly connected to an internal hex bolt 16. An installation plug is fixed to the outside of the positioning member 15. A connecting rod 17 is slidably connected inside the installation plug. A threaded drill bit 18 is fixedly connected to the bottom end of the connecting rod 17.

[0020] In use, the positions of two adjacent sets of single positioning rods 11 can be adjusted by rotating the threaded end 12. After adjusting to the appropriate position, the first limiting bolt 13 is screwed down to limit and fix the threaded end 12, so as to prevent the threaded end 12 from continuing to rotate and causing the angle to shift. The adjustment of the position of the single positioning rod 11 will affect the subsequent position adjustment of the positioning part 15. Then, the internal hex bolt 16 is loosened and the first half of the positioning part 15 is rotated. When the first half of the positioning part 15 rotates, it will drive the connecting rod 17 and the threaded drill bit 18 to rotate. After rotating to the appropriate position, the internal hex bolt 16 is tightened to limit and fix. Then, the threaded drill bit 18 is moved up and down by rotating the connecting rod 17.

[0021] The fixed drill bit 2 includes a connector 21. The connector 21 has a threaded opening on its outer side. A second limiting bolt 22 is threadedly connected to the threaded opening. A rotating ball head 23 is rotatably connected to one side of the front end of the connector 21. Two sets of rotating ball heads 23 are symmetrically installed on both sides of the front end of the connector 21. A drill bit storage tube 24 is fixedly connected to the outside of each set of rotating ball heads 23. A bone tunnel drill bit 26 is slidably connected inside the drill bit storage tube 24. Several sets of positioning holes 27 are opened on the surface of the bone tunnel drill bit 26. An opening is opened at the top of the drill bit storage tube 24, and a limiting pin 25 is inserted into the opening.

[0022] The limiting pin 25 corresponds to several sets of positioning holes 27, the second limiting bolt 22 corresponds to the connecting rod 17, and the first limiting bolt 13 corresponds to the threaded end 12.

[0023] The connector 21 is inserted into the top of the connecting rod 17 to achieve the combined installation of the fixed drill bit 2 and the positioning bracket 1;

[0024] When adjusting the position of the fixed drill bit 2, the second limiting bolt 22 can be loosened to adjust the position of the connector 21 on the connecting rod 17. After confirming the position, tighten the second limiting bolt 22. The drill bit storage tube 24 can be adjusted to any angle by rotating the ball head 23. Then, the bone tunnel drill bit 26 can be slid in the drill bit storage tube 24 to adjust the length. Then, the limiting pin 25 is inserted downward into the corresponding positioning hole 27 to achieve the limiting and fixing of the bone tunnel drill bit 26.
