[0002] In orthopedic surgery, doctors may use a variety of different types of knives, which depends on the type of surgery and the bone part, etc. An orthopedic box knife is a medical device specifically used in orthopedic surgery to cut bones, soft tissues or other materials during surgery. It usually consists of a handle, a blade and a protective cover, and is designed to provide precise cutting and operation.

[0003] During surgery, doctors usually hold a box knife to perform cutting operations. Doctors holding a box knife can achieve more precise cutting and trimming because they can directly control the position, angle and pressure of the knife. This direct manual operation allows doctors to make fine adjustments according to actual conditions to achieve the desired cutting effect.

[0004] However, since most doctors work for a long time, long-term manual operation may cause fatigue of doctors, resulting in decreased hand-eye coordination and concentration during the operation, which may affect the accuracy and stability of cutting. At the same time, long-term manual operation may cause hand muscle fatigue and tremor, thus affecting the stability of the hand. This may lead to unstable tool position and cutting errors. Therefore, a box knife guide for orthopedics is proposed to solve the above problems. Utility Model Content

[0030] 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.

[0031] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a box knife guide for orthopedics, including a rotating rod 5, both sides of the outer wall of the rotating rod 5 are fixedly connected with a bracket 6, the bracket 6 is rotatably connected with a rotating column 7, one side of the inner part of the rotating rod 5 is fixedly connected with a motor 10, the output end of the motor 10 is fixedly connected with a gear 11, one side of the outer wall of the rotating column 7 is fixedly connected with a rack 12, the rack 12 is meshed with the outer wall of the gear 11, one side of the outer wall of the rotating column 7 is fixedly connected with a motor 2 14, the output end of the motor 2 14 is fixedly connected with a screw rod 15, the outer wall of the screw rod 15 is threadedly connected with a movable block 16, the outer wall of the movable block 16 is slidably connected to the inside of the rotating column 7, a sliding groove 13 is opened on one side of the inner part of the rotating column 7, and the outer wall of the movable block 16 is slidably connected to the inside of the sliding groove 13;

[0032] Specifically, when the motor 10 drives the gear 11 to rotate, the gear 11 will be driven by the rack 12 on the outer wall of the rotating column 7, so that the rotating column 7 starts to rotate inside the bracket 6. At the same time, the motor 2 14 drives the screw rod 15 to rotate, and the screw rod 15 is connected to the movable block 16. When the screw rod 15 rotates, the movable block 16 will slide inside the slide groove 13. The movable block 16 is connected to the blade 8. Therefore, when the movable block 16 slides inside the slide groove 13, it will drive the blade 8 to move laterally.

[0033] Reference Figure 1 A support assembly is provided at the bottom of the rotating rod 5, and the support assembly includes a bottom column 2 and a base 1. One side of the bottom of the rotating rod 5 is rotatably connected to the bottom column 2, and the bottom of the bottom column 2 is fixedly connected to the base 1. One side of the outer wall of the bottom column 2 is rotatably connected to an electric push rod 3, and the output end of the electric push rod 3 is fixedly connected to a connecting shaft 4, and the outer wall of the connecting shaft 4 is rotatably connected to one side of the inside of the rotating rod 5;

[0034] Specifically, the rotating rod 5 is located at the top of the bottom column 2 and supported by the base 1. The rotating rod 5 can rotate around the rotating axis at the top of the bottom column 2. One side of the rotating rod 5 is pushed through the electric push rod 3 and the connecting shaft 4. When the electric push rod 3 moves, the connecting shaft 4 will transmit force to the rotating rod 5, causing it to rotate around the rotating axis. When the rotating rod 5 rotates, the blade 8 will also change height accordingly.

[0035] Reference Figure 2 and Figure 3 A mounting column 18 is fixedly connected to one side of the outer wall of the movable block 16, a fixed column 21 is slidably connected inside the mounting column 18, a blade 8 is fixedly connected to one side of the fixed column 21, a sliding ring 17 is slidably connected to the outer wall of the mounting column 18, a circular array of card balls 20 are slidably connected inside the mounting column 18, a card slot 9 is opened on the outer wall of the fixed column 21, the card ball 20 is slidably connected inside the card slot 9, a spring 19 is arranged inside the sliding ring 17, one end of the spring 19 is fixedly connected to one side of the outer wall of the mounting column 18, and the other end of the spring 19 is fixedly connected to one side of the inner wall of the sliding ring 17;

[0036] Specifically, one end of the fixed column 21 is fixed to the tail of the blade 8, and the mounting column 18 is located on one side of the movable block 16. The operator inserts the raised part of the fixed column 21 into the mounting column 18, and loosens the sliding ring 17. The sliding ring 17 will slide outward under the action of the spring 19, and the card ball 20 can be pushed out of the mounting column 18. The card ball 20 will be stuck in the card groove 9 opened on the outer wall of the fixed column 21, thereby fixing the position of the blade 8 on the movable block 16.

[0037] Working principle: When adjusting the position of the blade 8, the gear 11 can be driven by the motor 10, and the gear 11 can be driven by the rack 12 on the outer wall of the rotating column 7, so that the rotating column 7 can be controlled to rotate inside the bracket 6, and at the same time, the motor 2 14 can drive the screw rod 15 to rotate, so that the screw rod 15 drives the movable block 16 to slide inside the slide groove 13, which can drive the blade 8 to move horizontally, and the rotating rod 5 rotates at the top of the bottom column 2, and can be supported by the base 1 at the bottom of the bottom column 2. At the same time, the electric push rod 3 can push one side of the rotating rod 5 through the connecting shaft 4, so that the rotating rod 5 is rotated at the top of the bottom column 2, so as to control the height of the blade 8. When the blade 8 is replaced, the fixed column 21 fixed at the tail end of the blade 8 can be inserted into the mounting column 18 fixed on one side of the movable block 16. When inserting, the sliding ring 17 should be slid inwards, so that the locking ball 20 can be retracted into the mounting column 18. After the fixing column 21 is inserted, the sliding ring 17 can be loosened, and the sliding ring 17 will slide outwards under the action of the spring 19, so that the locking ball 20 can be pushed out of the mounting column 18, and the locking ball 20 will be locked in the locking groove 9 provided on the outer wall of the fixing column 21, so that the blade 8 is fixed.

[0038] 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.
