[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please refer to Figures 1-3. This invention provides a technical solution: a drive mechanism for an interventional surgical robot, comprising: a housing 1, interconnected with an external surgical machine; the housing 1 includes a bottom housing 101; a side housing 102 is movably connected to the front of the bottom housing 101; a top housing 103 is fixedly connected inside the side housing 102; quick-release structures 2 are movably connected to both sides of the top of the bottom housing 101; and a drive module 3 is fixedly connected to the back of the inner wall of the bottom housing 101; the quick-release structures 2 are connected to both sides of the top of the bottom housing 101, and include a main connecting plate. 21. A compression spring 22 is movably connected to the front of the main connecting plate 21. A pin 23 is movably connected to the top of the surface of the main connecting plate 21. A latch 24 is movably connected to the surface of the pin 23. Connecting blocks 25 are fixedly connected to both sides of the top of the end side shell 102. The transmission module 3 is connected to the back of the inner wall of the end bottom shell 101. The transmission module 3 includes a fixed end 31. A support end 32 is provided on the left side of the fixed end 31. A lead screw 33 is movably connected to the inner side of the support end 32. A threaded sleeve 34 is threaded to the surface of the lead screw 33. A fixed plate 35 is fixedly connected to the top of the fixed end 31.

[0030] Please refer to Figures 1-2. The transmission mechanism of the interventional surgical robot includes the outer shell 1, which also includes a U-shaped plate 4, which is fixedly connected to the top of the bottom shell 101. Protective sleeves 5 are fixedly connected to both the front and back of the U-shaped plate 4. The U-shaped plate 4 can increase the contact area between the bottom shell 101 and the hand, thereby facilitating the user to move the bottom shell 101. The fixed end 31 also includes a motor 6, which is fixedly connected to the right side of the fixed end 31. The output end of the motor 6 is fixedly connected to the lead screw 33. The output end of the motor 6 will drive the lead screw 33 to rotate. The connecting block 25 also includes an L-shaped fixing block 7, which is set on both sides of the top of the connecting block 25. The bottom of the L-shaped fixing block 7 is fixedly connected to the top of the connecting block 25. The back of the L-shaped fixing block 7 is fixedly connected to the back of the inner wall of the bottom shell 101. The L-shaped fixing block 7 can increase the connection area between the connecting block 25 and the bottom shell 101, preventing the bottom shell 101 from separating from the connecting block 25.

[0031] 9. The connecting block 25 also includes a guide rail 8, which is located on the top of the connecting block 25. A slider 9 is slidably connected to the bottom of the guide rail 8. The inside of the slider 9 is fixedly connected to the threaded sleeve 34. The guide rail 8 and the slider 9 can fix the threaded sleeve 34 to prevent it from rotating. The support end 32 also includes an anti-collision block 10, which is located on the right side of the support end 32. The inside of the anti-collision block 10 is movably connected to the surface of the lead screw 33. The left side of the anti-collision block 10 is fixedly connected to the support end 32. The anti-collision block 10 can protect the support end 32 to prevent it from colliding with the threaded sleeve 34. The protective sleeve 5 also includes: chamfers, which are set on both sides of the surface of the protective sleeve 5. The protective sleeve 5 is a rubber rod. Both sides of the protective sleeve 5 are fixedly connected to bending plates. The bottom of the bending plates is fixedly connected to the top of the bottom shell 101. The chamfers process the edges of the surface of the protective sleeve 5 to prevent the edges of the protective sleeve 5 from scratching the user's hands. The bottom shell 101 also includes: electrical components, which are fixedly connected to the back of the inner wall of the bottom shell 101. The electrical components are evenly distributed on the top of the transmission module 3. The electrical components can control the motor 6, so that the user can drive the output end of the motor 6 to rotate forward or reverse.

[0032] Working principle: For this type of surgical robot with a drive mechanism, the user first pulls the latch 24, which rotates around the pin 23, causing the latch 24 to separate from the connecting block 25. At the same time, the compression spring 22 is stretched, and then the end side shell 102 is separated from the main body connecting plate 21, exposing the transmission module 3. Then, the motor 6 is driven, which drives the lead screw 33 to move left and right. The lead screw 33 drives the screw sleeve 34 to move left and right, allowing the user to quickly check the transmission module 3. If the transmission module 3 malfunctions, it is convenient for the user to repair the transmission module 3.

[0033] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
