Power Blade Head: 1. The structure of the blade has a major impact not only on the shape of the excised tissue, but also on the surgical scenario. The ease of excision of the blade is closely related to the cutting force and the edge of the blade. 2. The size of the blade space determines the efficiency of tissue excision and is also related to the throughput during surgery. There is often feedback that jamming occurs during clinical use, and designers need to pay more attention to the design of the internal and external blade sizes. 3. The angle of the blade determines the target selection requirements of the surgery, which are usually divided into straight and curved shapes.

Universal Flexibility of the Power Blade Head: The flexibility of the power cutter head is generally reflected in the curved structure of the cutter head. Due to the advantage of local flexibility, surgical resection can be performed at any curved position without affecting its high-speed rotation, thus achieving multi-angle surgery. Of course, when designing the flexible structure, it is necessary to pay attention to the snap force, flexible torque, flexible airtightness, etc., which determine the overall surgical effect.

Power Blade Material: The choice of material for the power blade head is very important. When selecting the material, the corrosion resistance, hardness, edge structure adjustment, surface oxidation, deformation and other aspects of the material must be considered. At present, the materials commonly used for power cutter heads in the market are SUS420J2, SUS440, SUS455, 630, TC4, 631, SUS304 and other materials.

Departmental Use of Power Blade Heads: In addition to the common otolaryngology and ophthalmology departments, power blade heads are also used in urology, minimally invasive orthopedics, etc., but the application of other departments needs to be discussed. For example, long-distance sampling and resection of various soft tissues, multi-angle targeted applications, various local coating interferences of cutter heads, and peripheral structure products of various consumables under laparoscopy involve applications. Welcome to discuss the topic of minimally invasive power blade head structure application and realization with everyone.
