[0028] In order to enable those skilled in the art of this technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this application.

[0029] According to an embodiment of the present invention, a bone needle fixing device for multi-scene use is provided. Please refer to Figures 1 to 6, including: a fixed seat 1, the fixed seat 1 has a receiving cavity 11, at least two bone needle holes 12 are provided on the fixed seat 1, and the bone needle holes 12 are used for the bone needles 3 to pass through; a locking assembly 2, the locking assembly 2 includes a locking seat 21 and a locking member 22, the locking seat 21 is movably arranged in the receiving cavity 11, the locking member 22 passes through the fixed seat 1 and is detachably connected to the locking seat 21, and at least two abutting portions 23 are provided on the locking seat 21. When the bone needle 3 passes through the bone needle hole 12, the locking seat 21 is moved so that the abutting portion 23 abuts against the bone needle 3 located in the receiving cavity 11, thereby fixing the bone needle 3; when the locking member 22 is connected to the locking seat 21, each bone needle hole 12 is axially symmetrically arranged on the fixed seat 1 with the length extension direction of the locking member 22 as the axis of symmetry, and each abutting portion 23 is arranged corresponding to each bone needle hole 12 one by one. The diameter of the bone needle hole 12 is relatively large, and bone needles 3 with different diameters can pass through it. After the bone needle 3 passes through the bone needle hole 12, by moving the locking seat 21 so that the abutting portion 23 thereon tightly abuts against the bone needle 3, the bone needle 3 is abutted in the bone needle hole 12, and then the locking seat 21 is fixed by the locking member 22, thereby fixing both the locking assembly 2 and the bone needle 3 on the fixed seat 1. The bone needle holes 12 are axially symmetrically arranged on the fixed seat 1 with the length extension direction of the locking member 22 as the axis of symmetry. That is to say, after the fixed seat 1, the locking assembly 2 and at least two bone needles 3 are installed, with the length extension direction of the locking member 22 as the axis of symmetry, the structure is axially symmetrically arranged. This symmetric design can ensure that the locking member 22 faces the surgical operator regardless of whether the patient's diseased position is on the left or right side, making it easier to operate (whether the fixing device is in the placement posture as shown in Figure 1 or the placement posture after rotating 180° as shown in Figure 2 , the fixed seat 1 and the locking assembly 2 are both symmetric structures). The bone needle fixing device for multiple scenarios of the present invention solves the technical problem in the related art that due to different patient conditions, the use range of the bone needle fixator is limited due to the diameter of the bone needle and the diseased position.

[0030] Refer to Figure 1 , for the bone needle fixing device for multiple scenarios of this embodiment, there are two bone needle holes 12 and two abutting portions 23. The two bone needle holes 12 are respectively located at both ends of the fixed seat 1, and the two abutting portions 23 are respectively located at both ends of the locking seat 21. Taking the fixation of two bone needles 3 as an example, since the two abutting portions 23 are respectively located at both ends of the locking seat 21, when they simultaneously abut against the two bone needles 3 passing through the bone needle holes 12, a stable support structure can be formed.

[0031] Refer to Figure 1 and Figure 2, for the multi-scenario bone pin fixing device of this embodiment, the fixing base 1 includes an upper plate 13, a lower plate 14, a first fixing plate 15, a second fixing plate 16 and a third fixing plate 17. The upper plate 13 and the lower plate 14 are arranged at intervals and in parallel. The first fixing plate 15, the second fixing plate 16 and the third fixing plate 17 are all connected to the upper plate 13 and the lower plate 14 to form a receiving cavity 11. The bone pin hole 12 penetrates through the upper plate 13 and the lower plate 14; the first fixing plate 15 and the second fixing plate 16 are arranged oppositely, the third fixing plate 17 is located between the first fixing plate 15 and the second fixing plate 16, and a through hole 18 is provided on the third fixing plate 17. The locking member 22 passes through the through hole 18 and enters the receiving cavity 11 to be connected to the locking seat 21. The fixing base 1 is jointly composed of the upper plate 13, the lower plate 14, the first fixing plate 15, the second fixing plate 16 and the third fixing plate 17 and forms a firm receiving cavity 11. This structural design of the multi-layer board significantly enhances the rigidity and stability of the fixing base 1, making the entire device more stable and reliable when fixing the bone pin 3. The bone pin hole 12 penetrates through the upper plate 13 and the lower plate 14, ensuring that the bone pin 3 can be firmly inserted and fixed in the device.

[0032] Refer to Figure 1 , for the multi-scenario bone pin fixing device of this embodiment, the locking seat 21 includes a first connecting block 211, a second connecting block 212 and a third connecting block 213. The first connecting block 211, the second connecting block 212 and the third connecting block 213 are connected in sequence. Two abutting portions 23 are respectively arranged on the first connecting block 211 and the third connecting block 213, and the second connecting block 212 is connected to the locking member 22. The first connecting block 211 and the third connecting block 213 are like the "ears" of the second connecting block 212. The lengths of the first connecting block 211 and the third connecting block 213 are shorter than that of the second connecting block 212. Such a setting will not occupy too much space on both sides inside the fixing base 1, thus providing a larger operating space for the insertion of the bone pin 3, enabling medical staff to more easily pass the bone pin 3 through the bone pin hole 12 and accurately align it with the abutting portion 23 of the locking seat 21.

[0033] Refer to Figure 1 and Figure 3, for the multi-scenario bone needle fixing device of this embodiment, the two abutting parts 23 respectively protrude from the first connecting block 211 and the third connecting block 213. Each abutting part 23 includes a first protrusion 231 and a second protrusion 232, and the first protrusion 231 and the second protrusion 232 are arranged at intervals along the length direction of the bone needle 3. The spaced arrangement of the first protrusion 231 and the second protrusion 232 enables the bone needle 3 to be supported and constrained from two different positions when passing through the fixing base 1 and being clamped by the abutting part 23. This multi-point clamping method significantly enhances the stability of bone needle fixation and prevents the bone needle from shifting or loosening during use. On the other hand, when the bone needle 3 is subjected to an external force, due to the presence of the first protrusion 231 and the second protrusion 232, the stress will be dispersed to these two protrusions instead of concentrating on a certain point of the bone needle 3, which helps to reduce the risk of the bone needle 3 breaking due to stress concentration and improves the overall safety and reliability of the device.

[0034] Refer to Figure 1 , for the multi-scenario bone needle fixing device of this embodiment, the locking member 22 is a threaded rod 221, and a threaded hole 24 is provided on the second connecting block 212. The threaded rod 221 passes through the threaded hole 24 and is threadedly connected to the locking base 21. The threaded connection not only realizes the detachability between the locking member 22 and the locking base 21. When the abutting part 23 abuts against bone needles 3 with different diameters, due to the adjustability of the threaded connection, the threaded rod 221 can extend into the threaded hole 24 to different depths. This design enables the locking base 21 to be finely adjusted according to the diameter of the bone needle, ensuring that the abutting part 23 can tightly and firmly clamp the bone needle 3, and improving its flexibility and practicality in multi-scenario applications.

[0035] Refer to Figure 1 , for the multi-scenario bone needle fixing device of this embodiment, the multi-scenario bone needle fixing device further includes a reinforcing pin 4. When the locking base 21 is located in the accommodation cavity 11, a groove 25 is provided on the side of the second connecting block 212 close to the upper plate 13. The reinforcing pin 4 passes through the upper plate 13 and enters the groove 25 to reinforce the connection between the fixing base 1 and the locking base 21. The accommodation cavity 11 provides a moving space for the locking base 21 and also provides a connection method for the connection between the locking base 21 and the locking member 22. The design of the groove 25 not only provides a clear moving track and a limiting space for the reinforcing pin 4, but also prevents the locking base 21 from falling off from the accommodation cavity 11 after the threaded part of the locking base 21 and the locking member 22 are completely separated. When the reinforcing pin 4 passes through the fixing base 1 and enters the groove 25, they can only move in the length direction of the groove. This limiting effect also provides convenience for the connection between the locking base 21 and the locking member 22. The threaded connection and the fixing of the reinforcing pin 4 make the entire bone needle fixing device more stable when bearing an external force, reducing the risk of loosening or failure caused by vibration or impact.

[0036] Refer to Figure 1, for the multi-scenario bone pin fixing device of this embodiment, the groove 25 extends along the length direction of the locking member 22, there are at least two reinforcing pins 4, and at least two reinforcing pins 4 are arranged at intervals along the length direction of the groove 25. Compared with a single reinforcing pin, the arrangement of more than two reinforcing pins 4 further enhances the connection stability between the fixing base 1 and the locking base 21, and prevents the locking base 21 from moving out of the accommodation cavity 11 after loosening between the locking base 21 and the locking member 22.

[0037] Refer to Figure 4 , Figure 5 and Figure 6 , for the multi-scenario bone pin fixing device of this embodiment, the multi-scenario bone pin fixing device further includes a connection assembly 5. The connection assembly 5 includes a first connection assembly 51, a second connection assembly 52 and a fastener 53. The first connection assembly 51 is connected to the first fixing plate 15, the second connection assembly 52 is connected to the tracer 6 for positioning and guiding the surgery, and the fastener 53 connects the first connection assembly 51 and the second connection assembly 52 so that the fixing base 1 is connected to the tracer 6. The fastener 53 is detachably arranged relative to the first connection assembly 51 and the second connection assembly 52. The detachable setting facilitates that during the operation, medical staff can quickly adjust the position of the tracer 6 or replace the tracer 6 according to needs, thereby improving the operation efficiency.

[0038] Refer to Figure 4 , for the multi-scenario bone pin fixing device of this embodiment, a first disk tooth 54 is arranged on the first connection assembly 51, and a second disk tooth 55 is arranged on the second connection assembly 52. When the fastener 53 connects the first connection assembly 51 and the second connection assembly 52, the first disk tooth 54 and the second disk tooth 55 are connected by meshing action to prevent relative rotation between the first connection assembly 51 and the second connection assembly 52. In orthopedic surgery, the accuracy of bone pin fixation is crucial for the success of the surgery. The meshing design of the disk teeth enables the first connection assembly 51 and the second connection assembly 52 to be firmly combined after fastening, effectively preventing relative rotation caused by external forces or minute vibrations during the operation, thereby enhancing the stability of the bone pin fixing device.

[0039] In this embodiment, the connection assembly 5 further includes a connecting rod 56, and there are multiple connection assemblies 5. Adjacent two connection assemblies 5 are connected by the connecting rod 56. The setting of the connecting rod 56 provides a broader field of view for positioning and navigation (as shown in Figure 5 and Figure 6 ). The number and connection structure of the connection assembly 5 include but are not limited to the structures shown in Figure 5 and Figure 6 .
