Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an orthopedic medical hammer with a replaceable hammer head. Background Art

[0002] Orthopedics is a branch of medicine that specializes in the study and treatment of diseases and injuries related to bones, joints, muscles, and related structures. This includes fractures, joint diseases (such as arthritis), muscle injuries, ligament injuries, etc. In some fracture cases, a medical hammer can be used to reposition and fix the bone in the correct position to promote healing. This process is called fracture reduction. Different types of surgery or treatment may require hammers of different shapes or sizes to meet the needs of surgery or treatment. Therefore, the need to use a medical hammer with a replaceable hammer head allows the doctor to choose the appropriate hammer head according to the specific situation.

[0003] During the use of a traditional orthopedic medical hammer with a replaceable hammer head, a rubber cap is set and pressed, and the rubber cap is deformed under force, so that the positioning block squeezes the limiting block, the limiting block squeezes the compression spring, the compression spring is deformed under force, and the limiting block is separated from the positioning hole. The connecting rod can be moved to the right to separate the connecting rod from the connecting block and the fixed block in turn. When the connecting rod is installed, the connecting rod is plugged into the fixed block, the connecting block enters the inside of the connecting rod, and the limiting block is snap-fitted into the positioning hole, thereby achieving the purpose of facilitating the replacement of the hammer handle.

[0004] However, it does not solve the problem that it is inconvenient to install the cone head. The operator needs to use matching tools to screw the bolt between the cone handle and the cone head to fix it. The installation process is inconvenient, which affects the installation efficiency of the orthopedic medical hammer. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an orthopedic medical hammer with a replaceable hammer head, aiming to improve the problem that the operator needs to use a matching tool to screw the bolt between the cone handle and the cone head for fixation, which is inconvenient during the installation process.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3, the utility model provides an embodiment: an orthopedic medical hammer with a replaceable hammer head, comprising a cone handle 1, a card slot 4 is opened inside the cone handle 1, a cone head 2 is arranged on the top of the cone handle 1, a connecting column 3 is fixedly connected inside the cone head 2, a sealing assembly is arranged at the bottom of the cone head 2, a limit plate 5 is slidably connected inside the connecting column 3, a support rod 7 is rotatably connected inside the limit plate 5, a locking block 6 symmetrically arranged is rotatably connected inside the connecting column 3, one end of the support rod 7 is rotatably connected inside the locking block 6, a telescopic rod 8 is arranged inside the connecting column 3, a first spring 9 is sleeved on the outer wall of the telescopic rod 8, one end of the telescopic rod 8 and the first spring 9 are fixedly connected to the top of the limit plate 5, the other end of the telescopic rod 8 and the first spring 9 are fixedly connected inside the connecting column 3, the outer wall of the connecting column 3 is slidably connected to the inside of the cone handle 1, and the sealing assembly comprises a sealing ring 16, the top of the sealing ring 16 is fixedly connected to the bottom of the cone head 2, and the bottom of the sealing ring 16 fits on the top of the cone handle 1;

[0031] Specifically, in the process of installing the cone head 2, first, gently insert the cone head 2 into the interior of the cone handle 1 through the connecting column 3. Next, the locking block 6 in the connecting column 3 is embedded in the inner side of the card slot 4. This process is achieved by connecting the support rod 7 with the limit plate 5, which can ensure that the position of the locking block 6 is accurate and will not shift. After completing the above steps, we need to use the power of the first spring 9 to support the locking block 6 to ensure that it is firmly embedded in the card slot 4 to prevent sliding during use. Next, the sealing ring 16 plays a vital role. It can effectively prevent blood and other substances from entering the interior of the cone handle 1 to ensure the cleanliness and safety of the equipment.

[0032] Reference Figure 2 A fixing column 10 is fixedly connected to the outer wall of the cone handle 1, and the fixing column 10 is symmetrically arranged and fixedly connected to the outer wall of the cone handle 1. A limiting groove 11 is provided inside the fixing column 10, and a limiting plate 12 is arranged inside the fixing column 10. The outer wall of the limiting plate 12 is slidably connected to the inside of the limiting groove 11. A pressure rod 13 is fixedly connected to one side of the limiting plate 12, and the outer wall of the pressure rod 13 is slidably connected to the inside of the fixing column 10. A top block 14 is fixedly connected to the other side of the limiting plate 12, and the outer wall of the top block 14 is slidably connected to the inside of the card slot 4. A second spring 15 is sleeved on the outer wall of the top block 14, and one end of the second spring 15 is fixedly connected to the other side of the limiting plate 12, and the other end of the second spring 15 is fixedly connected to the inside of the fixing column 10;

[0033] Specifically, during the disassembly of the cone head 2, first, it is necessary to press the pressure rods 13 on both sides. This pressure rod 13 plays a key role, and it will drive the top block 14 to move. Next, driven by the pressure rod 13, the top block 14 will extend into the slot 4. In this process, the top block 14 will squeeze the locking block 6. This step is to allow the cone head 2 to be smoothly pulled out from the cone handle 1. After completing the above steps, the cone head 2 is directly pulled out to separate it from the cone handle 1. In this process, it will be found that the cone head 2 can easily detach from the cone handle 1, because the top block 14 squeezes the locking block 6. Finally, when the disassembly of the cone head 2 is completed, it is only necessary to release the pressure rod 13. At this time, the tension of the second spring 15 will push the limit plate 12 to return the top block 14 to its original position, completing the entire disassembly process.

[0034] Working principle: when using the orthopedic medical hammer with a replaceable hammer head, first install the cone head 2, just need to insert the cone head 2 directly into the cone handle 1 through the connecting column 3, and engage the locking block 6 in the connecting column 3 into the card slot 4, the locking block 6 is connected to the connecting column 3 through the support rod 7 and the limit plate 1 5 for limiting, and supported by the tension of the first spring 9, so that the locking block 6 is engaged in the card slot 4 and will not slide out, then the cone head 2 and the cone handle 1 are sealed by the sealing ring 16 to prevent blood from entering the cone handle 1 during use, and then when the cone head 2 needs to be removed, just press the pressure rods 13 on both sides, and drive the top block 14 to extend into the card slot 4 through the pressure rods 13, so that the top block 14 squeezes the locking block 6, and then directly pull out the cone head 2 to separate it from the cone handle 1, and then release the pressure rod 13 to push the limit plate 2 12 through the tension of the second spring 15 to drive the top block 14 to reset.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
