Fixing material for department of orthopedics and fixing method thereof

Abstract

The orthopedic fixing material is compounded with two components, A and B in the weight ratio of 100 to 50-80. The component A is isocyanate; and the component B consists of polyether glycol 30-67 wt%, cross linking agent 10-20 wt%, foam homogenizing agent 1-5 wt%, calcium carbonate 10-15 wt%, white carbon black 6-10 wt%, catalyst 0.5-1 wt% and other stuffing 5-20 wt%. The fixing process with the fixing material includes: making fixing bag with cotton fabric in the required shape and size; mixing component A and component B in the required ratio, filling the mixture into the bag, rolling to level, setting in required position, curing to form and to reach the fixing effect. The present invention has the advantages of light weight, high strength, simple operation, capacity for X-ray to penetrate, good anastomosing property, capacity of being detached and being waterproof.

Description

1. Technical field [0001] The invention relates to a medical material and its application method, in particular to an orthopedic fixation material and its fixation method. 2. Background technology [0002] Medical clinical treatment of various fractures and patients after orthopedic surgery requires external fixation. Existing orthopedic external fixation generally adopts common gypsum and various wood, bamboo, paper splints, etc., and is mainly based on common gypsum. This is a long-term customary clinical product with a history of more than 70 years. Although ordinary gypsum and other materials have been used as orthopedic external fixation materials for many years, there are still many defects in clinical use, such as comfort, fit, poor air permeability, heavy, can not penetrate X-rays, and it is inconvenient to review the fracture healing of patients , afraid of water, and ordinary plaster cannot be disassembled and used repeatedly once it is fixed, and fracture patient...

AI Technical Summary

Problems solved by technology

Although ordinary gypsum and other materials have been used as orthopedic external fixation materials for many years, there are still many defects in clinical use, such as comfort, fit, poor air permeability, heavy, can not penetrate X-rays, and it is inconvenient to review the fracture healing of patients , afraid of water, and ordinary plaster cannot be disassembled and used repeatedly once it is fixed, and patients with fractures are often accompanied by trauma and surgery, which affects medical staff dressing changes, wound care, stitches removal, and patients' functional recovery exercises

At the same time, the operation of ordinary plaster is complicated and has certain technical difficulties. For example, it takes about 2 doctors to complete a patient with head, neck and chest fixation, and the operation takes 1-2 hours to complete.

In addition, some patients currently use polymer bandages, thermoplastic splints and other materials in clinical practice, but the use of such materials does not change the operation mode of external fixation. Cannot be fixed, especially in more complex positions
