Detailed Description

In the existing product, the cutter head of the energy knife such as a medical ultrasonic knife only carries out anti-sticking treatment on an executor (an ultrasonic rod), while the medical protection arm does not carry out anti-sticking treatment, and the surface reason is as follows: the existing actuator is of a non-open-hole slotted structure, and the four surfaces of the actuator are continuous surfaces, so that the anti-sticking treatment of the actuator is easy to realize; and the surface of the medical protection arm is a non-continuous surface with holes or grooves, so that the anti-sticking treatment of the medical protection arm is difficult to realize. The deep essential reasons are: firstly, because the surface of the medical protection arm facing the actuator needs to be provided with the protection pad, and the medical protection arm needs to be provided with mounting structures such as mounting grooves and the like on the surface facing the actuator for mounting the protection pad, and grooves or holes for clamping need to be arranged on the surface of the medical protection arm back to the actuator for processing the mounting structures such as the mounting grooves and the like, the back surface of the medical protection arm is a non-continuous surface with grooves and holes, and the structures such as the grooves and the like on the non-continuous surface are easy to clamp and stick tissues; secondly, the non-continuous surface is difficult to adhere with anti-sticking materials; thirdly, even if the adhesion-preventing material is adhered to the discontinuous surface, due to the existence of the slotted hole structure, the area where the slotted hole is located is still a non-release adhesion area, the structures such as the slotted hole are still easy to clamp and adhere tissues, and even if the adhesion-preventing material is adhered to the back surface of the medical protection arm, the adhesion-preventing effect cannot be achieved. For the reasons, the medical protection arm in the existing product is easy to adhere tissues.

In the application, the applicant processes the medical protection arm by a special processing technology, so that at least the back surface and/or the side surface of the medical protection arm is a continuous surface, the continuous surface is a complete surface without structures such as holes or grooves, and the medical protection arm is provided with an installation groove for installing the front surface. The continuous medical protection arm has better anti-sticking effect, and the back and/or the side are continuous, so that the anti-sticking layer is easier to be added, and the anti-sticking effect is improved.

The structure of the medical protection arm is further improved on the basis of the continuous surface and the anti-sticking layer, if the medical protection arm is set to be a gradual change structure and the duckbill structure is arranged at the front end of the medical protection arm, the anti-sticking efficiency can be further improved, and the medical protection arm is beneficial to the movement of the medical protection arm in a human body.
