Description

Technical Field

[0001] The utility model belongs to the field of mechanical equipment, and particularly relates to an electric bone saw with a safety protection structure. Background Technique

[0002] A medical bone saw is a medical device used for cutting human bones. It usually consists of components such as a blade, a motor, a handle, and a controller. It is usually made of high-strength materials and is designed to handle bone tissues during surgery. Medical staff bone saws are mainly used in surgical operations such as orthopedic surgery, neurosurgery, cardiac surgery, etc.;

[0003] During the use of the bone saw, it is necessary to accurately locate the bone part to be cut or trimmed. This process may require the use of X-rays or other imaging techniques to assist in determining the position. However, since the bone saw generates vibrations during operation, when medical staff hold it with both hands, the operation is more cumbersome and requires more hand coordination and operation skills. When holding it with one hand, due to the reduced control force on the bone saw, the vibrations of the bone saw are more likely to cause hand fatigue of medical staff, thereby affecting the operation accuracy of medical staff and increasing the risk of misoperation, making the cutting or trimming of the bone part less safe.

[0004] Therefore, we hope to design an electric bone saw with a safety protection structure to solve this problem. Content of the Utility Model

A sleeve 312 is connected to the outside of the second threaded rod 311 through a thread. The right end of the second threaded rod 311 is connected to the output shaft of a reduction gear 313 through a bushing. The output shaft of the reduction gear 313 penetrates through the support frame 1, and the reduction gear 313 is fixedly connected to the support frame 1. The electric telescopic rod 33 is fixedly installed on the outside of the sleeve 312. By arranging the transmission assembly 31, the sleeve 312 drives the electric telescopic rod 33 to generate displacement.

[0025] The limiting assembly 32 includes a slider 321. The slider 321 is fixedly connected to the outside of the sleeve 312. A chute 322 is opened on the lower side of the upper end of the support frame 1. The upper end of the slider 321 is slidably sleeved inside the chute 322. By arranging the limiting assembly 32, the sleeve 312 is prevented from rotating along with the second threaded rod 311.

[0026] The clamping component 2 includes a lower clamping block 21. The lower clamping block 21 is fixedly connected to the inside of the lower end of the support frame 1. A support plate 22 is fixedly connected to the inside of the lower end of the support frame 1. A first threaded rod 23 is connected to the inside of the support plate 22 through a thread. The lower end of the first threaded rod 23 is connected to an upper clamping block 24 through a bearing. A positioning assembly 25 is arranged at the upper end of the first threaded rod 23. By arranging the clamping component 2, the equipment is fixed.

[0027] The positioning assembly 25 includes a resisting rod 251. The resisting rod 251 is slidably sleeved on the upper end of the first threaded rod 23. A tension spring 252 is arranged on the outside of the resisting rod 251. The upper end of the resisting rod 251 is fixedly connected to a fixing block 253. The fixing block 253 is elastically connected to the upper end of the first threaded rod 23 through the tension spring 252. A rubber gasket is arranged at the lower end of the resisting rod 251. The rubber gasket is used to enhance the friction between the resisting rod 251 and the upper surface of the first threaded rod 23. By arranging the positioning assembly 25, the clamping is prevented from loosening due to the rotation of the first threaded rod 23.

[0028] Rubber pads are arranged on the inner sides of the upper clamping block 24 and the lower clamping block 21. The rubber pads are used to enhance the friction between the upper and lower clamping blocks 21 and the object to be clamped.

[0029] Please refer to Figures 1 - 3, as the first embodiment of the present utility model: To solve the problem that the bone saw will vibrate during operation, which is more likely to cause hand fatigue of medical staff, thus affecting the operation accuracy of medical staff and increasing the risk of misoperation, making the cutting or trimming of bone parts less safe. When the device needs to be used, first rotate the first threaded rod 23. A threaded movement occurs between the first threaded rod 23 and the support plate 22, causing the upper clamping block 24 connected to the first threaded rod 23 through a bearing to displace. When the upper clamping block 24 is displaced to a stable clamping state, stop rotating the first threaded rod 23. Then start the speed reducer 313. The output shaft of the speed reducer 313 drives the second threaded rod 311 to rotate. A threaded movement occurs between the second threaded rod 311 and the sleeve 312, causing the sleeve 312 to displace. While the sleeve 312 is displacing, the electric telescopic rod 33 fixedly connected to it simultaneously drives the connecting plate 34 to displace. The connecting plate 34 drives the mounting ear 35 and the bone saw body 4 to displace. When the bone saw body 4 is displaced to the position for excising necrotic bone, start the electric telescopic rod 33 and the bone saw body 4 through the control system. The electric telescopic rod 33 drives the connecting plate 34 and the bone saw body 4 to move downward to excise the necrotic bone.

[0030] Please refer to Figures 1 - 3 , as the second embodiment of the present utility model: Based on the description in the above embodiment, further, after the clamping is stable, the abutting rod 251 is pulled by the pulling force of the tension spring 252 to move the fixed block 253 downward. During the movement of the fixed block 253, it drives the abutting rod 251 to move downward until the rubber gasket at the lower end of the abutting rod 251 contacts the upper surface of the first support plate 22. The rubber gasket can enhance the friction between the abutting rod 251 and the surface of the support plate 22, preventing the first threaded rod 23 from rotating and causing the clamping to loosen. At the same time, during the threaded movement between the second threaded rod 311 and the sleeve 312, the slider 321 fixedly connected to the sleeve 312 is affected by the resistance of the support frame 1, causing the sleeve 312 to move linearly along the second threaded rod 311.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
