Description

Technical Field

[0001] This utility model belongs to the technical field of stapler pusher assembly equipment, and specifically relates to an anti-slip surface structure for stapler pusher assembly equipment. Background Technology

[0002] As a crucial tool in modern surgery, the stability and anti-slip performance of the stapler's pusher assembly device are paramount during operation. However, traditional stapler pusher assembly devices often use smooth materials, such as ordinary stainless steel. These materials can easily become slippery in wet or bloody environments, increasing the risks associated with surgical procedures. Especially in delicate surgeries, such as microsurgery, the device's anti-slip performance directly impacts the precision and safety of the procedure.

[0003] To improve the anti-slip performance of stapler pusher assembly equipment, the industry has made various attempts. For example, some manufacturers have added anti-slip textures or coatings to the surface of the equipment, but these methods often suffer from insufficient durability, limited anti-slip effect, or affect the aesthetics of the equipment. In particular, these anti-slip measures are prone to wear or failure after prolonged use or frequent contact with liquids.

[0004] Therefore, there is an urgent need to provide an anti-slip surface structure for a stapler pusher assembly device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide an anti-slip surface structure for a stapler pusher assembly device, in order to solve the technical problem that existing anti-slip measures are often prone to wear or failure.

[0006] To solve the above-mentioned technical problems, this utility model provides an anti-slip surface structure for a stapler pusher assembly device, comprising: a substrate, wherein the substrate is provided with a micro-protrusion array, the micro-protrusion array includes a stainless steel layer, and the stainless steel layer is provided with a nano-coating.

[0007] As further explained, the micro-bump array is uniformly distributed on the substrate surface, and each individual bump in the micro-bump array is a truncated pyramid shape.

[0008] As further explained, the bottom surface dimensions of each individual protrusion in the micro-protrusion array are 0.5mm × 0.5mm, and the height is 0.2mm. The distance between any two individual protrusions in the micro-protrusion array is 0.3mm.

[0009] As further explained, the substrate is made of stainless steel and has a thickness of 5mm.

[0010] As further explained, the nanocoating is composed of tungsten-doped diamond-like carbon and has a thickness of 50 nm.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By combining a micro-protrusion array and a nano-coating, this invention effectively improves the anti-slip performance of the stapler pusher assembly device. Even in wet or liquid environments such as blood, it maintains a stable anti-slip effect, reducing the risks associated with surgical procedures.

[0012] 2. The combination of a stainless steel layer and a tungsten-doped diamond-like carbon nanotube coating gives the anti-slip surface structure excellent wear resistance and corrosion resistance. Meanwhile, the truncated pyramidal design of the micro-protrusion array enhances anti-slip performance while maintaining a pleasing aesthetic appeal.

[0013] 3. The anti-slip surface structure of this invention ensures stability and precision during surgery, reducing surgical risks caused by equipment slippage. This is especially important for delicate surgeries such as microsurgery.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figure 1-3 An anti-slip surface structure for a stapler pusher assembly device includes: a substrate 1, on which a micro-protrusion array 2 is provided, the micro-protrusion array 2 including a stainless steel layer 201, and a nano-coating 202 on the stainless steel layer 201. The combination of the protrusion array 2 and the nano-coating 202 greatly increases the surface roughness of the device, thereby improving the anti-slip effect. Moreover, both the stainless steel layer 201 and the nano-coating 202 have high hardness and wear resistance, and can resist wear caused by prolonged use and frequent contact with liquids.

[0021] like Figure 1-3 As shown, the micro-protrusion array 2 is uniformly distributed on the surface of the substrate 1, and each protrusion of the micro-protrusion array 2 is a truncated pyramid shape. The truncated angle of 5° avoids tissue snagging (reducing the damage rate by 70% compared to the traditional pointed cone structure), and the four beveled surfaces of the pyramid shape provide multi-directional anti-slip (the difference in friction coefficient in each direction is <5%), ensuring the uniformity and stability of the anti-slip effect.

[0022] like Figure 1-3 As shown, the bottom surface dimensions of each protrusion in the micro-protrusion array 2 are 0.5mm × 0.5mm, and the height is 0.2mm. The spacing between any two individual protrusions in the micro-protrusion array 2 is 0.3mm. This ensures a protrusion density of 400 protrusions / cm², achieving optimal friction / cleaning balance; moreover, it perfectly matches the size of the staples (typically Φ0.3-0.5mm), avoiding interference with the precision of the surgical procedure.

[0023] like Figure 1-3 As shown, substrate 1 is made of stainless steel with a thickness of 5mm. Stainless steel has high strength and corrosion resistance, and finite element analysis (FEA) verifies that its bending stiffness is ≥2.1×10⁻⁶. 5 N·mm²; First-order natural frequency > 500Hz (to avoid resonance during surgical procedures); These data indicate that the device can resist various stresses and corrosion during surgery.

[0024] like Figure 1-3As shown, the nano-coating 202 is composed of tungsten-doped diamond-like carbon and has a thickness of 50 nm. Tests have shown that its wear resistance is three times higher than that of pure DLC, increasing the lifespan of the device. Furthermore, the high hardness of the tungsten-doped diamond-like carbon material allows the nano-coating 202 to resist wear and corrosion over a longer period, thus maintaining a stable anti-slip effect. In addition, this material also exhibits good chemical stability, resisting the erosion of various chemicals and liquids that may be encountered during surgery.

[0025] In summary, this utility model provides an anti-slip surface structure for a stapler pusher assembly device with excellent anti-slip performance, durability, and aesthetics, providing a safer and more reliable tool for surgical operations.
