DETAILED DESCRIPTION

[0021] The present application will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it, but the embodiments are not limiting to the present application.

[0022] The purpose of the embodiment of the present application is to, during umbilical surgery, the existing preoperative treatment scheme mostly uses the method of wiping the surface with a cotton swab dipped in disinfectant, but it is difficult to effectively clean the deep wrinkles of the umbilical fossa due to the narrow operation field and poor instrument adaptability, so it is necessary to solve the problem that the umbilical region and the surrounding peripheral region (such as the umbilical orifice and the umbilical fossa) cannot be effectively and deeply cleaned before surgery.

[0023] The embodiment of the present application discloses a preoperative cleaning device for cleaning the umbilical region and the surrounding peripheral region, referring to Figures 1-4The system includes a claw structure and a drive mechanism 2. The claw structure includes a pair of claws 1, each claw 1 having an outer wall surface that acts on the target area. The outer wall surface is arc-shaped, and the arc of the outer wall of the claw 1 gradually increases from the proximal end to the distal end. Each claw 1 includes a fixed part 11 and a rotating part 12 that is rotatably connected to the fixed part 11 via a connecting shaft 111. The drive mechanism 2 is connected to the pair of claws 1 and is used to drive the pair of claws 1 to retract or expand. When the pair of claws 1 expands, they act on the target area to expose the parts that are covered by the target area.

[0024] refer to Figures 1-4 The support claw structure includes a pair of support claws 1. The support claws 1 are made of plastic material, which has low material stress and can easily fit the internal structure surface of the human body without damaging the internal tissue. The support claws 1 have an outer wall surface that acts on the target area. The outer wall surface has an arc-shaped structure. The outer wall surface of the support claws 1 can be divided into a proximal end that first touches the target area and extends into it and a distal end that is positioned opposite to the proximal end. The arc of the proximal end is smaller than that of the distal end.

[0025] refer to Figures 1-4 A smaller radius of curvature at the proximal end indicates a higher thickness of the proximal support claw 1. As the cleaning opening becomes larger, the distance the support claw 1 extends into the umbilicus also increases. The increased thickness of the proximal support claw 1 also enhances the support force on the subcutaneous tissue in the target area that is in contact with the proximal end, enabling more stable support of the subcutaneous opening near the opening, making it easier for operators to perform cleaning operations.

[0026] refer to Figures 1-4 The support claw 1 can be divided into a fixed part 11 near the proximal end and a rotating part 12 near the distal end. The proximal end mainly cooperates with the drive mechanism 2 to adjust the position of the support claw 1. Under the drive of the drive mechanism 2, the pair of support claws 1 can move away from each other to open up the target area or move closer to each other and retract.

[0027] refer to Figure 3 , 4 The support claw structure also includes an adjusting torsion spring 1101, which is sleeved on the connecting shaft 111; wherein, when a pair of support claws 1 close or open to make the rotating part 12 rotate relative to the fixed part 11, the adjusting torsion spring 1101 applies an elastic resistance force to the rotating part 12 around the connecting shaft 111, and the radius of curvature of the arc surface near the outer wall of the support claw 1 is greater than the radius of curvature of the arc surface far from the outer wall of the support claw 1.

[0028] refer to Figure 3 , 4In another embodiment, the curvature radius of the arc surface of the outer wall of the support claw 1 at the proximal end can be greater than the curvature radius of the arc surface of the outer wall of the support claw 1 at the distal end. The greater the curvature radius, the smaller the arc. Within the bending numerical range of the national standard, the curvature radius of the arc surface of the outer wall of the support claw 1 at the proximal end can reach a maximum value, and the proximal end approaches a vertical state. The curvature radius of the distal end can reach a maximum bending state within the range in which the pair of support claws 1 can be buckled. The ratio of the curvature radius of the proximal end to the curvature radius of the distal end is preferably between 1.5 and 2.0, so as to better adapt to the internal tissues and skin of the human body. A sufficiently large bending state can effectively buffer and support the subcutaneous fat layer and skin tissue of the navel.

[0029] Reference Figure 3 , 4 The rotating part 12 is connected with the fixed part 11 through a connecting shaft 111. The rotating part 12 can rotate around the circumference of the connecting shaft 111. The rotation angle of the rotating part 12 relative to the fixed part 11 is maximally 60°. An adjusting torsional spring 1101 is sleeved on the connecting shaft 111. One end of the adjusting torsional spring 1101 is fixed on the fixed part 11, and the other end is fixed on the rotating part 12. When the rotating part 12 rotates, the adjusting torsional spring 1101 will contract and generate an elastic counterforce to restore the rotating part 12 to the original position. In the process of cleaning, the skin is pressed together and extruded, and the elastic counterforce can support the skin. In the process of using the support claw 1 for navel surgery, the fat layer and various subcutaneous tissues inside the navel are not smooth structures, which will generate a pressing force on the outer wall of the distal end of the rotating part 12. At this time, the rotating part 12 will be driven to rotate to buffer the force between the outer wall of the rotating part 12 and the body tissue, reduce the stiffness of the contact surface of the rotating part 12, protect the skin tissue, and improve the stress adjustment ability of the support claw 1 itself.

[0030] Reference Figure 3 , 4 In another embodiment, the support claw 1 can also be made of a high-elasticity material. The Shore hardness coefficient of the material is between 50 and 80, which is a rubber material. This material can also support the human skin tissue by adjusting the stress of its own elasticity.

The contact surface of the rotating part 12 of the support claw 1 is provided with a guide rubber strip. A guide round corner is formed at the end of the guide rubber strip. The stress concentration coefficient of the guide round corner is less than 1.3.

[0032] Reference Figure 4At the distal end of the support claw 1, the surface of the target area is provided with a nanoscale micro groove body by laser opening. The micro groove body surface will produce fine grooves and protrusions to cooperate and adhere to the skin tissue at the micro level. Before pre-cleaning, lubricating oil is applied to the surface of the contact surface of the support claw 1 to facilitate the reduction of the friction of the support claw 1. The lubricating oil reduces the friction of the contact surface of the support claw 1 on the surface of the skin tissue. The micro groove body opened by the laser can adsorb the lubricating liquid under capillary action, so that the lubricating liquid stays on the contact surface of the support claw 1 for a longer time, and the damage to the skin tissue is smaller.

[0033] Reference Figure 4 In another embodiment, the groove body opened by the laser can be fish scale type or arrayed rhombus, which can set more micro holes in a unit area, enhance the capillary effect of the contact surface, and enhance the adsorption capacity of the lubricating oil.

[0034] Reference Figure 4 A guide rubber strip is attached to the outer wall surface of the rotating part 12 of the support claw 1. The guide rubber strip is made of softer medical rubber material, which can further reduce the material shore hardness of the contact surface of the rotating part 12. A guide round corner is provided at the end of the guide rubber strip, and the stress concentration coefficient of the guide round corner is less than 1.3, which achieves the softness of the rubber. The stress concentration coefficient less than 1.3 will not damage the internal tissues of the human body, and the softness of the surface of the guide rubber strip is strengthened. When the support claw 1 is inserted into the subcutaneous tissue, it can flexibly contact the skin tissue to prevent the rigidity and friction of the material from damaging the skin tissue.
