Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a locking structure for a oscillating saw blade. Background Technology

[0002] Medical devices refer to various tools, equipment, and instruments used for the diagnosis, monitoring, treatment, and relief of diseases. These devices cover a wide range, including simple surgical tools, complex imaging equipment, and even high-end implants. Taking the oscillating saw as an example, it is a commonly used medical device in surgical procedures, especially in orthopedic surgery. The oscillating saw is favored by doctors for its precise cutting ability and efficient operation. It can precisely cut bone tissue during surgery, thereby reducing surgical risks and accelerating the patient's recovery process. Compared with traditional surgical tools, the use of the oscillating saw makes surgery safer and faster, reflecting the importance of continuous progress and innovation in medical devices.

[0003] The output end of existing oscillating saw guns typically uses a spring-loaded snap-fit ​​structure to connect the oscillating saw blade. This connection method provides good stability and cutting effect in the initial use, but over time, the spring-loaded snap-fit ​​structure is prone to wear, causing the connection to become loose. The wear of the spring-loaded snap-fit ​​structure is mainly due to long-term vibration and friction generated during the cutting process. This wear not only makes the connection between the saw blade and the oscillating saw gun loose, but may also cause the saw blade to deviate during the oscillation. This deviation will directly affect the cutting accuracy, and thus affect the quality of the final product. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1-5 As shown, in this embodiment, a locking structure for a oscillating saw blade includes a mounting handle 1. The top of the mounting handle 1 is fixedly connected to an oscillating saw gun body 2. One end of the oscillating saw gun body 2 is fixedly connected to a U-shaped block 4. The top of the U-shaped block 4 is rotatably connected to a first turntable 5. A transmission assembly is provided between the U-shaped block 4 and the bottom of the oscillating saw gun body 2. The transmission assembly is used to drive the first turntable 5 to rotate. A lifting plate 10 is provided above the first turntable 5. The bottom of the lifting plate 10 is rotatably connected to a second turntable 12. A saw blade body 19 is provided between the first turntable 5 and the second turntable 12. A lifting assembly is provided on one side of the oscillating saw gun body 2 and on top of the U-shaped block 4. The lifting assembly is used to drive the lifting plate 10 to move. A positioning groove 6 is provided on the top of the first turntable 5. A positioning block 13 is fixedly connected to the bottom of the second turntable 12. An adjusting block 11 is rotatably connected to the top of the lifting plate 10. One end of the adjusting block 11 passes through the lifting plate 10 and is fixedly connected to the second turntable 12. A control button 20 is fixedly installed on one side of the mounting handle 1.

[0023] When installing the saw blade body 19, first connect the mounting hole on the saw blade body 19 to the first turntable 5. Then manually adjust the adjusting block 11 so that the second turntable 12 at the bottom of the lifting plate 10 is parallel to the first turntable 5. Then use the lifting assembly to drive the lifting plate 10 to move downward so that the positioning block 13 at the bottom of the second turntable 12 extends into the positioning groove 6, thereby locking the saw blade body 19 between the first turntable 5 and the second turntable 12.

[0024] After installation, pressing the control button 20 causes the swing assembly to swing the first turntable 5 on top of the U-shaped block 4, thereby causing the saw blade body 19 to swing synchronously. The lifting assembly drives the lifting plate 10 to move, effectively realizing the cooperation between the first turntable 5 and the second turntable 12, thereby locking the swing saw blade. This design improves the efficiency of saw blade replacement and also facilitates the application of the swing saw in medical work.

[0025] like Figures 1-5 As shown, the lifting assembly includes a mounting plate 7, which is fixedly connected to one side of the swing saw gun body 2. A lifting screw 8 is rotatably connected between the mounting plate 7 and the U-shaped block 4. The outer side of the lifting screw 8 is threadedly connected to the lifting plate 10. A lifting motor 9 is fixedly installed on the top of the mounting plate 7. The output end of the lifting motor 9 passes through the mounting plate 7 and is fixedly connected to the lifting screw 8.

[0026] The lifting screw 8 is driven to rotate by the lifting motor 9, which causes the lifting plate 10 on the outside of the lifting screw 8 to move up and down. This facilitates the movement of the second turntable 12 through the lifting plate 10, so that the first turntable 5 and the second turntable 12 cooperate to lock the saw blade body 19.

[0027] like Figures 1-5 As shown, the transmission assembly includes a transmission box 18, which is fixedly connected between the U-shaped block 4 and the bottom of the oscillating saw gun body 2. A power roller 15 is rotatably connected between the oscillating saw gun body 2 and the inner wall of the transmission box 18. A transmission roller 16 is rotatably connected between the U-shaped block 4 and the inner wall of the transmission box 18. A transmission belt 17 is provided between the power roller 15 and the transmission roller 16. One end of the transmission roller 16 passes through the U-shaped block 4 and is fixedly connected to the first turntable 5. A receiving groove 3 is provided inside the oscillating saw gun body 2. An oscillating motor 14 is fixedly installed inside the receiving groove 3. The output end of the oscillating motor 14 extends to the outside of the oscillating saw gun body 2 and is fixedly connected to the power roller 15. Heat dissipation holes 21 are provided on both sides of the oscillating saw gun body 2, and both heat dissipation holes 21 communicate with the receiving groove 3.

[0028] The oscillating motor 14 drives the power roller 15 to move, which causes the transmission roller 16 to move synchronously under the action of the transmission belt 17. This allows the saw blade body 19 to oscillate at an angle of 10 according to actual usage requirements. This ensures that the saw blade is not prone to jamming during the cutting process, and also increases the contact area between the cutting surface and the workpiece, thereby improving sawing efficiency.

[0029] This utility model provides a locking structure for a oscillating saw blade. The specific working principle is as follows: When installing the saw blade body 19, first connect the mounting hole on the saw blade body 19 to the first turntable 5. Then manually adjust the adjusting block 11 so that the second turntable 12 at the bottom of the lifting plate 10 is parallel to the first turntable 5. Then, use the lifting motor 9 to drive the lifting screw 8 to rotate, so that the lifting plate 10 on the outside of the lifting screw 8 moves up and down. This facilitates the movement of the second turntable 12 through the lifting plate 10, so that the first turntable 5 and the second turntable 12 cooperate to lock the saw blade body 19.

[0030] After installation, pressing the control button 20 causes the swing motor 14 to drive the power roller 15 to move, which in turn causes the transmission roller 16 to move synchronously under the action of the transmission belt 17. This allows the saw blade body 19 to swing at an angle of 10 according to actual usage needs, further realizing the medical efficacy of the swing saw.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
