Embodiment 1

[0042] This embodiment is a more preferred solution.

[0043] Such as Figure 1-5 As shown, the surgical scalpel for children in this embodiment mainly includes a handle 100 , a blade assembly 200 and a scale adjustment assembly 300 , and the handle 100 includes an upper handle body 110 and a lower knife cover 120 . The blade assembly 200 includes a receiving block 210 and a blade 220 , and the blade assembly 200 is disposed in the knife case 120 . Specifically, the blade 220 is detachably connected to the bottom end of the receiving block 210 , the receiving block 210 and the blade 220 are both arranged in the knife case 120 , and the receiving block 210 is slidably installed on the inner wall of the knife case 120 . The receiving block 210 is slidably installed on the inner wall of the knife cover 120, specifically: the two sides of the receiving block 210 are provided with convex lines, and the inner wall of the knife cover 120 is provided with a chute matching the convex ...

Embodiment 2

[0052] This embodiment expands the function of the scalpel in Embodiment 1.

[0053] In this embodiment, a miniature camera module 400 and a wireless communication module 500 are installed on the outer wall of the lower part of the tool holder 120, and a small battery can be used to provide power to the miniature camera module 400 and the wireless communication module 500. A small battery for power, or another small battery. The miniature camera module 400 mainly includes a processor and an image sensor, and the wireless communication module 500 is connected to the processor. The image sensor is used to collect images of the operation process and send them out through the wireless communication module 500 . The wireless communication module 500 may be a short-distance communication module, such as a Bluetooth communication module, and the collected images are sent to the receiving device. The surgical image received by the receiving device can be used as a learning reference...

Embodiment 3

[0056] This embodiment will provide a preparation process of the blade of the present invention, of course, other preparation processes can also be used, and it is not limited thereto.

[0057] First, prepare the green bodies of the first ceramic layer and the second ceramic layer by using ceramic materials; then, print the heating layer 221 on the inner surface of the first ceramic layer or the second ceramic layer, and make electrode leads at both ends of the heating layer 221 end 222; then, the first ceramic layer and the second ceramic layer are laminated and laminated; finally, the heatable blade of the present invention is obtained by sintering at a high temperature.

Abstract

The invention discloses an operating knife for pediatric surgery. The operating knife mainly comprises a knife handle, a blade assembly, a heating assembly, and a size adjusting assembly. The knife handle comprises a handle body in the upper part and a knife sheath in the lower part. The blade assembly is arranged in the knife sheath and can slide relative to the inner wall of the knife sheath. Aheating cavity is arranged in the blades, the heating assembly is arranged in the heating cavity and is used to heat the blades, and the size adjusting assembly is arranged in the handle body and is detachably connected to the blade assembly. The provided operating knife is safer, is more easy to control, and is suitable for the pediatric surgeries which have more higher requirements on the safety. The invention is funded by 2017 National Natural Science Foundation of China and 2018 Sanming Engineering (SZSM201812055) of Shenzhen Municipal Health Commission.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and mainly relates to medical auxiliary tools, in particular to a surgical scalpel for children. Background technique [0002] Existing scalpels often cannot effectively fix the blade head, making it easy to injure patients or medical staff during use, increasing the work risk of medical staff, and making the health of medical staff unable to be guaranteed. In addition, the palms of the medical staff tend to sweat during use, resulting in slippage and affecting the surgical effect. At present, the function of the scalpel is relatively single, and it cannot meet the needs of the medical staff well during use, which is not conducive to the use of the medical staff. Especially for children's surgical knives, children are weaker than adults. If the scalpel is not well controlled during children's surgical operations, it will not only affect the surgical effect, but may also accidentally in...
