Problems solved by technology

[0003] 1. The smoothness of the silicone block is low, which makes the cutting of the surgical scissors not flexible enough, difficult to cut, or difficult to cut, or difficult to pass through the needle and thread, time-consuming and laborious, and the practice effect is poor
[0004] 2. Because the surface is not smooth enough, it is easy to wrinkle during use, and repeated wrinkling for a long time will make the epidermis tear and affect the use

Abstract

The invention relates to a simulated medical human skin closure silica gel block with high smoothness and a preparation method thereof. The innovative point of the invention is as follows: the types of components are increased, and the component proportioning is optimized; the smoothness of the simulated medical human skin closure silica gel block is enhanced by increasing the types of raw materials in a lubricant and smearing softened water and castor oil to the surface of a finished surface in the preparation process while the anti-tear performance of the finished product is enhanced by means of intermittent high-temperature ageing treatment and low-temperature freezing treatment; and the phenomenon of difficulty in tailoring and suturing is avoided. The simulated medical human skin closure silica gel block is convenient to use, prolonged in service life and cost-saving, avoids waste of resources, is efficiently used, and is suitable for being widely popularized and applied to medical colleges, medical laboratories and hospitals.

Description

technical field [0001] The invention belongs to the field of medical supplies, and relates to silica gel products, in particular to a high-smooth simulated medical human body skin suture silica gel block and a preparation method thereof. Background technique [0002] The simulated medical human skin suture silicone block refers to the silicone block used for surgical suture practice, which can include: incision, various suture techniques, knotting, thread cutting, stitch removal, etc. A variety of surgical basic exercises, practice experience and The visual effect is real, and different depths of incision and suture can be performed at any position, and it can be used multiple times. It simulates the toughness and characteristics of human skin. It can be used by junior surgeons to practice skin suture. It feels real and can be used repeatedly. The portable design makes it convenient for simulation training. It is widely used in medical schools, medical laboratories and hospi...
