[0025] Embodiment

[0026] Please refer to Figures 1-6 , the present utility model provides a technical solution: a reinforcement structure for a medical device handle, including a grip rod mechanism for installing and reinforcing the instrument handle 1. The grip rod mechanism includes a connecting grip rod 2, a switching slider 3, and an adsorption magnet 4. The instrument handle 1 can be made of plastic or non-magnetic alloy material, and the connecting grip rod 2 can be made of composite plastic material. For the convenience of the plug-in installation of the instrument handle 1, as shown in the attachedFigure 1 As shown, a handle slot 5 is provided at the front part of the connecting grip 2. The handle slot 5 is opened in the middle of the front side of the connecting grip 2, and the rear fitting of the instrument handle 1 is inserted and installed inside the handle slot 5.

[0027] For the installation and positioning of the connecting grip 2, as shown in the appendix Figure 1 As shown, a positioning notch 6 is provided at the upper part of the front side of the connecting grip 2, and a positioning projection 7 is provided at the rear part of the instrument handle 1. The positioning projection 7 is adapted to the positioning notch 6, and the positioning projection 7 is fitted and connected with the positioning notch 6. For the convenience of discharging cleaning water, as shown in the appendix Figure 5 As shown, a drain through hole 12 is communicated and opened at the rear part of the handle slot 5. The inside of the installation notch structure has no complex corners and notch structures, is not easy to hide dirt, and is convenient to clean.

[0028] For the convenience of the installation and limit of the connecting grip 2, a limit plug post 9 is movably fitted and installed at the rear part of the instrument handle 1. For the convenience of the installation and connection of the limit plug post 9, as shown in the appendix Figure 1 As shown, a plug post installation hole 8 is provided at the upper part of the rear end of the instrument handle 1. The limit plug post 9 is movably fitted and installed inside the plug post installation hole 8. For the convenience of the adsorption and limit of the limit plug post 9, a strong magnetic head post 10 is provided at the lower part of the limit plug post 9. The strong magnetic head post 10 is a strong rubidium magnet. The strong magnetic head post 10 is fixed at the lower end of the limit plug post 9. The strong magnetic head post 10 movably penetrates through the lower part of the rear end of the instrument handle 1 and can move up and down and slide in the plug post installation hole 8 following the limit plug post 9. For the closure of the upper part of the plug post installation hole 8, as shown in the appendix Figure 6 As shown, a closing stud 11 is provided at the upper part of the plug post installation hole 8. The closing stud 11 is threadedly connected to the upper opening side of the plug post installation hole 8.

[0029] For the plug-in installation with the limit plug post 9, as shown in the appendix Figure 6 As shown, a limit jack is provided inside the handle slot 5. The limit jack is non-through opened at the lower part of the inner side of the handle slot 5. For the convenience of the sliding installation of the switching slider 3, as shown in the appendix Figure 4As shown in the figure, a slider mounting groove 13 is provided at the lower part of the connecting grip 2. The switching slider 3 is slidably fitted and mounted inside the slider mounting groove 13. The adsorption magnet 4 is a circular magnet, and the magnetic pole distribution is opposite to that of the strong magnetic head post 10. The adsorption magnet 4 is fixedly and penetratingly fitted to the front part of the switching slider 3. The adsorption magnet 4 slides and is mounted on the lower part of the connecting grip 2 following the switching slider 3. After the plug-in installation, through the magnetic adsorption between the strong magnetic head post 10 and the adsorption magnet 4 on the upper part of the switching slider 3, the adsorption and limitation of the limiting plug post 9 are realized, which can ensure the stable installation of the instrument handle 1 and the connecting grip 2. When disassembling, only need to push the switching slider 3 backward, and the limiting plug post 9 will move out of the adsorption limitation of the adsorption magnet 4, then the disassembly and unlocking of the instrument handle 1 can be realized. The structure is simple and the operation is convenient. Compared with the traditional bolt installation structure, it has better disassembly and assembly convenience. And through the setting of the adsorption magnet 4, after the cleaning operation or during daily storage, the adsorption and fixation of the connecting grip 2 can be completed through magnetic adsorption, which is beneficial to the storage and placement of the connecting grip 2. In order to facilitate the sliding limit of the switching slider 3, as shown in the appendix Figure 4 As shown in the figure, an adsorption iron block 14 is provided inside the slider mounting groove 13. The adsorption iron block 14 is fixedly fitted to the upper part inside the slider mounting groove 13. When the switching slider 3 is in the non-locking position, the adsorption iron block 14 is magnetically adsorbed to the adsorption iron block 14, which can prevent the switching slider 3 from sliding.

[0030] During the working principle or structural principle, during installation, keep the connecting grip 2 and the instrument handle 1 in an inverted state. At this time, the limiting plug post 9 in the plug post mounting hole 8 retracts into the inside of the plug post mounting hole 8 under the action of its own weight. Then, keep the end of the instrument handle 1 in an inverted state and plug it into the inside of the handle slot 5. Then, turn the connecting grip 2 as a whole and fully plug the instrument handle 1 into the inside of the handle slot 5. When the limiting plug post 9 coincides with the limiting jack at the lower part of the handle slot 5, the strong magnetic head post 10 at the lower end of the limiting plug post 9 is fitted and plugged into the inside of the limiting jack. Then, push the switching slider 3 forward, and use the magnetic adsorption between the adsorption magnet 4 and the strong magnetic head post 10 to complete the adsorption and fixation of the limiting plug post 9, and complete the installation operation of the connecting grip 2. When disassembling, keep the connecting grip 2 in an inverted state, then push the switching slider 3 backward, lose the magnetic adsorption of the adsorption magnet 4, and the limiting plug post 9 moves out of the limiting jack under the action of its own weight and retracts into the inside of the plug post mounting hole 8, completing the disassembly and unlocking of the instrument handle 1. Then, pull out and remove the instrument handle 1 to complete the disassembly operation of the device.

[0031] In summary, the handle reinforcement structure of the present invention adopts a notch-fitting and magnetic column-limiting installation structure. The instrument handle 1 is fitted and inserted by using the handle slot 5 and the positioning notch 6. After installation, the installation limit of the instrument handle 1 is achieved by the insertion of the limit plug 9 into the internal limit jack of the handle slot 5. A strong magnetic head column 10 is provided at the end of the limit plug 9. After the plug-in installation, the adsorption limit of the limit plug 9 is achieved by the magnetic adsorption between the strong magnetic head column 10 and the adsorption magnet block 4 on the upper part of the switching slider 3, which can ensure the stable installation of the instrument handle 1 and the connecting grip 2. When disassembling, only need to push the switching slider 3 backward, and the limit plug 9 will move out due to the loss of the adsorption limit of the adsorption magnet block 4, then the disassembly and unlocking of the instrument handle 1 can be realized. The structure is simple and easy to operate, and has better disassembly and assembly convenience compared with the traditional bolt installation structure. Moreover, through the setting of the adsorption magnet block 4, after the cleaning operation or during daily storage, the connecting grip 2 can be adsorbed and fixed by magnetic adsorption, which is beneficial to the storage and placement of the connecting grip 2. And there is no complex corner and notch structure inside the installation notch structure, which is not easy to hide dirt and is convenient to clean.
