[0002] Orthopedic nail removal surgery is a common procedure in the field of orthopedics. It is mainly used to remove steel nails implanted after fractures or other orthopedic surgeries. The purpose of nail removal surgery is to remove the steel nails implanted during fractures or other orthopedic surgeries. When a fracture or other orthopedic condition has completely healed, internal fixation devices such as steel nails are usually no longer needed in the body, so surgical removal is required to avoid long-term irritation to surrounding tissues and potential risks.

[0003] An orthopedic nail removal device is a medical device used to remove steel nails, screws or other fixation objects implanted in human bones. When removing the screws, a rotation operation is required. The nail removal devices currently used generally remove the screws by rotating the entire device. This method of screw removal has poor stability and is likely to cause patients to feel unwell. In addition, during the operation, multiple repeated rotations are required, and the nail removal time is long. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0019] The present invention provides an embodiment, such as Figure 1 As shown, an orthopedic rapid nail removal device includes a handle 1, a mounting rod 2 fixed at one end of the handle 1, a first transmission gear 3 located on the side of the mounting rod 2 and vertically rotatably connected thereto, a rotating rod 4 coaxially rotatably connected to the end of the mounting rod 2 away from the handle 1, a second transmission gear 5 coaxially fixedly connected to the rotating rod 4, and a screwdriver mechanism 6 detachably connected to the end of the rotating rod 4 away from the mounting rod 2. In this embodiment, the handle 1 is a columnar structure and is coaxially arranged with the mounting rod 2. The first transmission gear 3 is meshed with the second transmission gear 5. The first transmission gear 3 is coaxially connected to a rotating handle 7. In order to protect the transmission structure, a shell structure surrounding the first transmission gear 3 and the second transmission gear 5 is fixedly connected to the mounting rod 2. The rotating rod 4 passes through the shell structure and rotatably cooperates with it. The rotating handle 7 passes through the shell structure and rotatably cooperates with it.

[0020] When removing nails, one hand holds the handle 1 so that the screwdriver mechanism 6 is aligned with the nail, and then keeps the handle 1 in a fixed position. The other hand then turns the rotary handle 7 to drive the screwdriver mechanism 6 to rotate and unscrew the nail. The nail can be unscrewed stably and quickly, and the screwdriver mechanism 6 is detachable, which is convenient for replacing screwdrivers of different models and is easy to store after use.

[0021] In order to facilitate the replacement of the screwdriver mechanism 6, in a further embodiment, as Figure 2 As shown, the end of the rotating rod 4 away from the mounting rod 2 is coaxially provided with a socket 401, and a position-limiting engaging mechanism 8 is provided in the socket 401. The screwdriver mechanism 6 includes a screwdriver handle 610 and a screwdriver head 620 at one end of the screwdriver handle 610. The screwdriver handle 610 can enter the socket 401 and cooperate with the position-limiting engaging mechanism 8 and cannot move.

[0022] Specifically, such as Figure 3As shown, the limit clamping mechanism 8 includes a movable groove 801, a clamping block 802, an elastic member 803, and a push rod 804 provided on the socket 401. In this embodiment, the elastic member 803 is a rigid spring. The side surface of one end of the clamping block 802 close to the mounting rod 2 is connected to the bottom of the movable groove 801 through the elastic member 803. In the initial state, the end of the clamping block 802 close to the mounting rod 2 protrudes from the movable groove 801 and is located in the socket 401, and the other end is located in the movable groove 801. The middle part of the clamping block 802 is rotatably connected to the wall of the movable groove 801, and the push rod 804 passes through the movable groove 801 from the outside of the rotating rod 4 and is in transmission cooperation with the clamping block 802. The side surface of the end of the screwdriver handle 610 away from the screwdriver head 620 is provided with a clamping groove 611 corresponding to the clamping block 802. The clamping block 802 cooperates with the clamping groove 611 to limit the relative rotation between the screwdriver mechanism 6 and the rotating rod 4, and to prevent the screwdriver mechanism 6 from falling off from the rotating rod 4.

[0023] When installing the screwdriver mechanism 6, when the screwdriver handle 610 is inserted into the insertion hole 401, the side of the screwdriver handle 610 first squeezes the clamping block 802, compressing the elastic member 803, causing the clamping block 802 to rotate, and the clamping block 802 as a whole completely enters the movable groove 801. When the clamping groove 611 corresponds to the clamping block 802, under the elastic force of the elastic member 803, the clamping block 802 enters the clamping groove 611, completing the installation work;

[0024] When disassembling the screwdriver mechanism 6, press the push rod 804 to push the clamping block 802 away from one end of the mounting rod 2, so that the clamping block 802 rotates into the movable groove 801, and the screwdriver handle 610 can be pulled out;

[0025] In order to facilitate the cooperation between the push rod 804 and the clamping block 802, in a further embodiment, the push rod 804 is connected to a limit block 805 located in the movable groove 801, and the end of the push rod 804 close to the clamping block 802 is provided with a slot 806, and one end of the slot 806 is formed into a Y-shaped structure. The end of the clamping block 802 away from the mounting rod 2 passes through the slot 806, so that the clamping block 802 is not easily misaligned with the push rod 804;

[0026] In order to improve the clamping stability and facilitate the removal of the screwdriver mechanism 6, the said limit clamping mechanism 8 is provided with two groups and is located on opposite sides. By pressing the push rods 804 on both sides with two fingers of one hand, the screwdriver mechanism 6 can be pulled out;

[0027] In order to facilitate the quick engagement of the engaging block 802 with the engaging slot 611, in a further embodiment, a plurality of guide slots 402 are further provided on both sides of the opening of the jack 401, and a guide block 612 corresponding to the guide slot 402 is provided on the side of the screwdriver handle 610. When the guide block 612 engages with the guide slot 402, the engaging block 802 exactly corresponds to the engaging slot 611.

[0028] In order to improve the stability of the cooperation between the screwdriver mechanism 6 and the rotating rod 4, in a further embodiment, a magnetic block 403 is fixedly provided in the guide groove 402 near one end of the mounting rod 2, and the guide block 612 is a magnet block.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
