Description

Technical Field

[0001] This utility model relates to the field of electric knife processing technology, specifically to a device for removing excess insulating coating from a localized part of an electric knife. Background Technology

[0002] As a core piece of equipment in modern surgery, the integrity of the insulating coating on the high-frequency electrosurgical unit directly determines the safety and quality of the surgery. This insulating layer is typically made of polytetrafluoroethylene (PTFE), ceramic, or other high-temperature resistant polymer materials, uniformly covering the surface of the metal substrate of the cutting head, with only exposed areas (such as the blade tip) to achieve precise energy output and effectively prevent accidental burns to non-target tissues. However, during the manufacturing process of the cutting head, excess coating inevitably solidifies in unintended areas. Therefore, precise local removal is necessary to ensure the safety and reliability of the electrosurgical unit in clinical use.

[0003] Chinese Patent Publication No. CN219748065U disclosed on March 20, 2023, a tool for scraping the insulation layer of an electric motor, including a blade. One end of the blade is provided with a main cutting edge, and one side of the blade is provided with a side cutting edge. One end face of the blade is provided with a hemispherical groove that can accommodate the top corner of the insulation seat, and a grinding element is provided in the hemispherical groove. This utility model provides a blade specifically for scraping off insulation layers. The main cutting edge at its tip can be fitted to the smooth surface of an insulating base to scrape off the insulating coating on the smooth surface. Its side cutting edges can be fitted to the corners or gaps of the insulating base to scrape off the insulating coating inside the gaps. Furthermore, a grinding element located in a hemispherical groove on one side of the blade can further scrape off the insulating coating at the top corner of the insulating base. The inner surface of the hemispherical groove can be fitted to the top corner of the insulating base to completely remove the insulating coating from the surface of the insulating base, improving maintenance efficiency. Although the above application has many beneficial effects, it still has the following shortcomings: the current operation method requires workers to hold the scraper by hand, which not only leads to low scraping efficiency but also easily results in the accidental scraping off of coatings that should not be removed due to improper operation, thereby damaging the insulation performance of the blade tip, resulting in poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an excess removal device for local insulating coating of an electrosurgical unit, comprising a mounting frame, a scraping port fixedly connected at the center of the mounting frame, a transmission mechanism provided on the mounting frame, the transmission mechanism comprising a support base, multiple clamping rollers and a receiving groove, a lead screw rotatably connected to one side of the support base, an electric motor fixedly mounted on the other side of the support base, a moving block slidably connected inside the receiving groove, a pusher fixedly connected to one end of the moving block, a moving rod slidably connected to the side rod of the pusher, a pusher fixedly connected to one side of the moving rod, and a spring fixedly connected to one side of the pusher.

[0006] Preferably, both the mounting bracket and the scraping opening are rectangular.

[0007] Preferably, the support base is fixedly connected to the front wall of the mounting bracket near the side end.

[0008] Preferably, there are eight clamping rollers in total, which are divided into two groups of four. The two groups of clamping rollers are symmetrically rotatably connected inside the mounting frame.

[0009] Preferably, the receiving groove is located on one side of the front wall of the mounting frame corresponding to the support seat.

[0010] Preferably, the lead screw is a reciprocating lead screw, and one side of the lead screw is fixedly connected to the output end of the electric motor.

[0011] Preferably, the moving block is threadedly connected to the lead screw.

[0012] Preferably, the pusher frame is C-shaped, and one side of the spring is fixedly connected to the side wall of the pusher frame side rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the transmission mechanism can accurately position the cutter head at the lateral center of the scraping opening, ensuring a stable working position. During operation, the transmission mechanism can drive the cutter head to reciprocate within the scraping opening, enabling the scraping layer within the scraping opening to efficiently and evenly remove excess coating from the cutter head. This eliminates the need for manual operation by staff, improving the processing efficiency of the cutter head. Furthermore, the rigid positioning provided by each clamping roller in the transmission mechanism effectively prevents the scraping layer from contacting and damaging the insulating coating on the cutter head body that does not need to be removed, thus ensuring that the insulation performance of the cutter head is not affected.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 The present invention provides the following technical solution:

[0021] An excess removal device for local insulating coating of an electrosurgical unit includes a mounting frame 1. A scraping port 2 is fixedly connected to the center of the mounting frame 1. A transmission mechanism 3 is provided on the mounting frame 1. The transmission mechanism 3 includes a support base 31, multiple clamping rollers 32 and a receiving groove 33. A lead screw 34 is rotatably connected to one side of the support base 31. An electric motor 35 is fixedly installed on the other side of the support base 31. A moving block 36 is slidably connected inside the receiving groove 33. A pusher frame 37 is fixedly connected to one end of the moving block 36. A moving rod 38 is slidably connected to the side rod of the pusher frame 37. A pusher block 39 is fixedly connected to one side of the moving rod 38. A spring 301 is fixedly connected to one side of the pusher block 39.

[0022] Both the mounting bracket 1 and the scraping port 2 are rectangular. The support base 31 is fixedly connected to the front wall of the mounting bracket 1 near the side end. The support base 31 provides support for the lead screw 34 and the electric motor 35. There are eight clamping rollers 32 in total, divided into two groups of four. The two groups of clamping rollers 32 are symmetrically rotatably connected inside the mounting bracket 1. The clamping rollers 32 can easily clamp the cutter head and facilitate the smooth movement of the cutter head. The receiving groove 33 is opened on the front wall of the mounting bracket 1 on one side corresponding to the support base 31. The receiving groove 33 facilitates the movement of the moving block 36. The motor provides support and guidance. The lead screw 34 is a reciprocating lead screw. One side of the lead screw 34 is fixedly connected to the output end of the electric motor 35. When the output end of the electric motor 35 rotates, it is easy to drive the lead screw 34 to rotate. The moving block 36 is threadedly connected to the lead screw 34. The lead screw 34 is easy to drive the moving block 36 to reciprocate in the receiving groove 33. The pusher frame 37 is C-shaped. One side of the spring 301 is fixedly connected to the side wall of the side rod of the pusher frame 37. The spring 301 is easy to drive the pusher block 39 to reset and move. The pusher frame 37 is easy to push the cutter head to move through the pusher block 39.

[0023] In use, move the moving rod 38 away from the mounting bracket 1. The movement of the moving rod 38 will cause the pushing block 39 to move. The movement of the pushing block 39 will compress and retract the spring 301 with the help of the side rod of the pushing frame 37. At this time, the distance between the side rod of the pushing frame 37 and the clamping roller 32 can easily accommodate the cutter head. Place one end of the cutter head between the upper and lower clamping rollers 32. Figure 3Then, the moving rod 38 is released. At this time, the spring 301 will drive the push block 39 and the moving rod 38 to reset. One side of the push block 39 will abut against the cutter head. Then, the electric motor 35 can be started. The output end of the electric motor 35 will rotate, which will drive the lead screw 34 to rotate. The rotation of the lead screw 34 will drive the moving block 36 to move. The moving block 36 will move towards the electric motor 35 inside the receiving groove 33. The receiving groove 33 provides space and guidance for the movement of the moving block 36. At this time, the moving block 36 will drive the push frame 37 to move. The push frame 37 will drive the push block 39 to move together through the spring 301 and the moving rod 38. The push block 39 will move towards the mounting frame 1 along with the push frame 37, pushing the cutter head towards the center position inside the mounting frame 1. The clamping roller 32 will rotate with the movement of the cutter head. At the same time, the clamping roller 32 can ensure that the cutter head is located at the center position between the mounting frame 1 and the scraping port 2. At this time, the push frame 37 When the pusher block 39 pushes the cutter head into the scraping opening 2, the area on the outer wall of the cutter head without excess coating will not contact the inner wall of the scraping opening 2, while the area with excess coating will scrape against the inner wall of the scraping opening 2. At this time, the excess coating on the moving cutter head will be removed by the inner wall of the scraping opening 2. When the pusher block 39 abuts against one side of the scraping opening 2, the lead screw 34 will drive the moving block 36 to reset. At this time, the moving block 36 and the pusher frame 37 reset. The other side rod of the pusher frame 37 will directly push the cutter head during the reset process, so that the cutter head resets and moves, thereby achieving the purpose of reciprocating removal of excess coating by the cutter head. This allows the scraping layer in the scraping opening 2 to efficiently and evenly remove excess coating from the cutter head. In addition, the rigid positioning and clamping provided by each clamping roller 32 in the transmission mechanism 3 effectively prevents the scraping layer from contacting and damaging the insulating coating on the cutter head body that does not need to be removed, thus ensuring that the insulation performance of the cutter head is not affected, making it highly practical.
