Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a bone plate holding wrench. Background Art

[0002] Bone plates are perforated plate-shaped internal fixation devices for fractures. They are often used in conjunction with bone screws or bone wires in clinical practice. They are divided into two categories: ordinary bone plates and compression bone plates. They can be made into strips, Y-shaped, L-shaped, T-shaped, etc. according to different uses.

[0003] In orthopedic surgery, bone plates often need to be placed at the site of the patient's fracture. However, human fractures are generally located inside the muscles, which is located deeper in the human body. At this time, if medical staff use their hands or other instruments to place the bone plates into the patient's body, it will be inconvenient to place them, and the bone plates may be unstable.

DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0029] See also Figure 1 - Figure 4 A bone plate holding wrench includes a hexagonal prism 100, a screw rod 200 is fixedly connected to the inside of one end of the hexagonal prism 100, a connecting rod 300 is fixedly connected to the surface of the end of the hexagonal prism 100 away from the screw rod 200, the hexagonal prism 100 and the connecting rod 300 are connected by a connecting assembly, a mounting hole 301 is opened on the surface of the end of the connecting rod 300 away from the hexagonal prism 100, a mounting rod 401 is arranged inside the mounting hole 301, and a threaded rod 400 is fixedly connected to the outside of the mounting rod 401, so that the hexagonal prism 100, the screw rod 200 and the connecting rod 300 can be fixedly connected to each other to form a complete wrench, and connected to the bone plate through the threaded rod 400.

[0030] The connecting assembly includes a fixing ring 101 fixed on the outer top surface of the hexagonal prism 100, and a swivel 102 is arranged inside the fixing ring 101. The swivels 102 are arranged in pairs, so that the swivels 102 can respectively fix and clamp the limit blocks 302 on both sides. An annular groove 103 is formed between the swivel 102 and the hexagonal prism 100, so that the limit block 302 can enter the annular groove 103 and be limited.

[0031] A connecting groove 104 is provided inside the hexagonal prism 100 on one side close to the fixed ring 101, and telescopic grooves 107 are provided on both sides of the inner wall of the connecting groove 104. A rotating groove 105 is provided inside the connecting groove 104, and the rotating groove 105 is connected to the telescopic groove 107. Block grooves 106 are provided on both sides of the surface of the hexagonal prism 100 close to one end of the fixed ring 101, and the block groove 106 is connected to the rotating groove 105. In this way, after the connecting block 303 enters the rotating groove 105 through the block groove 106, the connecting rod 300 is rotated until the connecting block 303 is rotated to the lower end of the telescopic groove 107, and then the connecting rod 300 is continued to be pushed to move toward the direction of the hexagonal prism 100, so that the connecting block 303 will enter the telescopic groove 107.

[0032] The connecting rod 300 is fixedly connected with connecting blocks 303 on both sides of the top near the hexagonal prism 100. The connecting block 303 enters the telescopic groove 107 through the block groove 106 and the rotating groove 105. The connecting rod 300 is fixedly provided with limit blocks 302 on both sides of the outside of one end near the hexagonal prism 100. The limit blocks 302 are located inside the annular groove 103. The limit blocks 302 and the connecting blocks 303 are staggered. When the connecting block 303 enters the telescopic groove 107, the limit blocks 302 will also be driven into between the rotating rings 102, and the rotating rings 102 are rotated again, so that the rotating rings 102 will fix the limit blocks 302.

[0033] The twisting rod 200 is perpendicular to the hexagonal prism 100 and the connecting rod 300, so that the twisting rod 200 will be horizontal outside the hexagonal prism 100. When the twisting rod 200 rotates, it can drive the hexagonal prism 100 and the connecting rod 300 to rotate, and the twisting rod 200 can be better held and used by the user.

[0034] The connecting rod 300 is trumpet-shaped, and the end of the connecting rod 300 away from the hexagonal prism 100 has a larger surface area. In this way, the connecting rod 300 will be thick at one end and thin at the other end, and the thick end will form a large circle, so that when it comes into contact with the bone plate, it will have a larger contact area. In this way, the connecting rod 300 and the bone plate will be more stable when connected, and will not shake easily.

[0035] The outer surfaces of the threaded rod 400 and the mounting rod 401 are both engraved with threads, so that when the connecting rod 300 is connected to the bone plate, the threaded rod 400 can enter the threaded hole inside the bone plate through the surface threads. Because the threads on the outside of the threaded rod 400 and the mounting rod 401 are opened in opposite directions, when the threaded rod 400 is rotated to enter the threaded hole of the bone plate, the mounting rod 401 will not fall out of the connecting rod 300 due to the rotation, thereby completing the connection between the connecting rod 300 and the bone plate.

[0036] Working principle: When the utility model is used, firstly, a suitable threaded rod 400 is selected according to the size of the threaded hole inside the bone plate, and then the threaded rod 400 is rotated and installed inside the connecting rod 300 through the installation rod 401;

[0037] When a bone plate needs to be implanted in a patient, the threaded rod 400 is aligned with the threaded hole inside the bone plate, and then the screw rod 200 is rotated to rotate the device into the bone plate, so that the device is tightly connected to the bone plate, and then the medical staff can hold the hexagonal prism 100 with one hand to lift and move the device and the bone plate together;

[0038] When the bone plate is moved to the outside of the position where the patient needs to install it, the device is moved to drive the bone plate to move into the patient's body until the bone plate is at the position where it needs to be installed. At this time, the medical staff installs and fixes the bone plate;

[0039] Then, when the bone plate is fixedly installed in the patient's body, the screw rod 200 is rotated to remove the threaded rod 400 from the bone plate, so that the device can be separated from the bone plate;

[0040] When the device completes the operation and the connecting rod 300 needs to be removed, replaced, cleaned and disinfected, the rotating ring 102 is first turned to rotate inside the fixed ring 101 until the rotating ring 102 no longer blocks the limit block 302, and then the connecting rod 300 is pulled to move away from the hexagonal prism 100 until the connecting block 303 enters the rotating groove 105, and then the connecting rod 300 is rotated until the connecting block 303 is rotated to the block groove 106, so that the hexagonal prism 100 and the connecting rod 300 can be separated, so that cleaning and disinfection can be carried out more conveniently.

[0041] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
