Embodiment Construction

[0057] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0058] Figure 1aIt is an energy-carrying minimally invasive scalpel 1 among medical scalpels, Figure 1b It is a common scalpel in medical scalpel 2, Figure 1c is a medical surgical scissors 3, Figure 1d is a medical surgical forceps 4, figure 2 is a cutting tool 5, image 3 Is a living knife6. The knife surface 11 of the energy-carrying surgical tool, the knife surface 21 of an ordinary scalpel, the shear surface 31 of medical surgery, and the tweezers surface 41 of medical surgery are the main parts where tissue adhesion occurs in the operation process. Contact friction and wear occurs, reducing the service life of the knife, and the knife surface 61 for daily use is prone to food sticking to the knife surface during use. A series of groove structures are processed on the surface of the tool according to certain rules to realize its...

Abstract

The invention relates to a structure capable of achieving self-lubricating on a tool surface. A tool can be a medical operation tool, a cutting tool or a domestic tool. According to the self-lubricating structure, specifically, a series of groove structures are machined on the surface of the tool according to certain rules, by utilizing capillary force of the groove structures, liquid is guided to be directionally transported, a liquid film is formed, so that the tool surface is wetted and lubrication and cooling effects are achieved, and adhesion is reduced. The groove structures comprise but not limited to wedge grooves, trapezoid grooves, dovetail grooves, taper grooves and height gradient grooves. According to the structure capable of achieving self-lubricating on the tool surface, by utilizing the capillary force in the grooves, the liquid is guided to be directionally transported, the liquid film is formed, sustainable self-lubrication of the tool surface is achieved, and lubrication and anti-adhesion are achieved; and tissue adhesion in the operative process is reduced, the durability of the cutting tool is improved, and the domestic tool is convenient to use.

Description

technical field [0001] The invention relates to a self-lubricating structure on the surface of a tool, more specifically, a groove structure processed on the surface of a tool, the groove structure relies on capillary force to guide liquid to wet the surface of the tool, and realizes the self-lubrication of the surface of the tool. A lubricating method belongs to the technical field of anti-sticking and drag reduction. Background technique [0002] During medical operations, when using scalpels, surgical tweezers, and surgical scissors for tissue cutting, due to the direct contact between the surface of the surgical instrument and the soft tissue, soft tissue often adheres to the surgical instrument. This adhesion can easily cause tissue tearing and bleeding. Cause pain, cause sequelae. Moreover, the adhesion of soft tissue will also affect the operation, increase the risk of operation, and bring potential danger. Adding a lubricating liquid to the surface of the surgical ...
