[0032] The protective component 200 is used to protect and sterilize the cutter head 103. The protective component 200 includes a protective sleeve 201 which is sleeved on the end of the functional tube 102. An external threaded ring 207 is fixed to the end of the protective sleeve 201. An annular internal threaded groove 208 which is threadedly connected to the outer ring surface of the external threaded ring 207 is formed at the end of the insulating plastic handle 101.

[0033] The inner ring surface of the protective sleeve 201 is provided with a plurality of arc-shaped mounting grooves corresponding to the blade head 103 in a circular array, and an ultraviolet sterilization lamp panel 202 is fixedly provided on the inner wall of the arc-shaped mounting groove. The protective component 200 also includes a connecting ring 203 embedded in the outer surface of the protective sleeve 201, and a sealing airbag ring 204 fixedly provided on the inner wall of the connecting ring 203. An inflatable airbag ring 205 is fixedly provided on the outer surface of the protective sleeve 201, and an inner wall of the inflatable airbag ring 205 is provided with an inflation tube 206 which is connected to the sealing airbag ring 204 and is used to inflate the sealing airbag ring 204 to expand it.

[0034] A connecting disk 209 is fixedly provided at the end of the protective sleeve 201, and the interior of the connecting disk 209 is a hollow structure. A charging power supply 2010 is fixedly provided on the inner wall of the connecting disk 209, and a button switch 2011 is provided on the surface of the connecting disk 209. The charging power supply 2010 and the button switch 2011 are electrically connected to a plurality of ultraviolet sterilization lamp panels 202 through wires.

[0038] Embodiment 2

[0039] On the basis of the first embodiment, and different from the first embodiment,

[0040] The outer surface of the cutter head 103 is plated with a protective layer, and the material of the protective layer is polytetrafluoroethylene.

[0041] The specific method is as follows:

[0042] Pretreatment of the blade 103: The blade 103 of the multifunctional surgical dissector is carefully cleaned and pretreated to ensure that the surface is free of oil, impurities and oxides, providing a good foundation for the subsequent coating process;

[0043] Selection and preparation of polytetrafluoroethylene coating: Select high-quality polytetrafluoroethylene coating, and mix and optimize the coating according to the material of the blade 103 and surgical requirements to ensure the stability and performance of the coating;

[0044] Coating operation: Use advanced spraying, dipping and other processes to evenly coat the polytetrafluoroethylene coating on the surface of the cutter head 103. During the coating process, strictly control the thickness and uniformity of the coating to ensure that the coating quality reaches the best state;

[0045] Curing and post-processing: Curing the coated cutter head 103 so that the polytetrafluoroethylene coating is firmly attached to the surface of the cutter head 103. After curing, necessary post-processing is performed, such as grinding and polishing, to improve the appearance quality and performance of the cutter head 103;

[0046] Quality inspection and packaging: The coated blade 103 is strictly inspected to ensure that the coating is free of defects and peeling, and meets the relevant medical device standards and requirements.

[0047] In the present embodiment, a protective layer is plated on the surface of the blade 103, and the material of the protective layer is polytetrafluoroethylene. Since the surface of the blade 103 of the existing Peng's multifunctional surgical dissector is mostly titanium-plated, tissue adhesion will occur after several uses. Polytetrafluoroethylene is non-adhesive, making it difficult for blood, tissue and other body fluids to adhere to the blade 103, thereby simplifying the cleaning process and reducing the risk of cross infection. In addition, the titanium plating process of the existing Peng's multifunctional surgical dissector is relatively complicated and requires special equipment and technology, so its initial manufacturing cost may be high, while the manufacturing process of the polytetrafluoroethylene coating is relatively simple and the cost is relatively low.

[0048] at the same time,

[0049] Polytetrafluoroethylene has excellent corrosion resistance and can resist the erosion of various chemicals, ensuring the stability and durability of surgical dissectors in complex surgical environments;

[0050] The non-adhesive nature of the PTFE coating makes it difficult for blood, tissue, and other body fluids to adhere to surgical instruments, simplifying the cleaning process and reducing the risk of cross infection;

[0051] Polytetrafluoroethylene has good biocompatibility and interacts gently with human tissue, reducing the risk of allergic reactions and rejection reactions;

[0052] The friction coefficient of polytetrafluoroethylene is extremely low, which makes surgical operations smoother, reduces friction between instruments and tissues, and helps reduce surgical trauma.

[0053] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
