The process of manufacturing continuously embedded large-pore plastics using controlled heat shrinkage techniques in the mold.

Abstract

OCR10KL (21 / 01 / 2569) This invention relates to a process for manufacturing porous, welded implantable plastics. Next, we move on to techniques for controlling heat shrinkage in molds, which consist of the following steps: The workpiece is shaped using a mold by initially heating the mold under cover. With materials that act as thermal insulators at temperatures of 50 to 300 degrees Celsius and allow them to cool. The process involves immersing the workpiece in a liquid medium at a temperature between 30 and 90 degrees Celsius. In order for the material components to form a porous structure in the said part. It dissolves, then covers the workpiece that has been immersed in the liquid medium and remains there. In wet conditions, the material acts as a thermal insulator and provides a secondary heating layer. The workpiece is heated to a temperature of 50 to 300 degrees Celsius and allowed to cool; the final step is... Immerse the workpiece in a liquid medium at a temperature of 30 to 90 degrees Celsius, depending on the material it is made of. Its function is to provide thermal insulation by covering the mold during the initial heating process, in conjunction with other coverings. The workpiece is made with a material that acts as a thermal insulator during the second heating process. The resulting workpiece should have a smooth surface, a uniform porous structure, a high porosity, and... The high liquid absorption capacity indicates that the workpiece obtained by this invention process has... The high degree of continuous large pores is suitable for use in surgical correction of deformities. Or for cosmetic purposes in various parts of the patient's body, such as the skull. The bones in the face, eyeball, jaw, and orbital bone, etc., are treated with porous plastic implants. Connected to this invention is a unique characteristic: it has a continuous, large network of pores to allow tissue... Inside the body, organisms can rapidly grow into these pores and become attached. The firm bond between the embedded plastic and the tissue is so strong and durable that it can be sutured with a needle. Easy to suture and fix with screws, exhibits similar shrinkage in all directions, has a smooth surface, and is non-toxic. It is biocompatible with the human body.
