Medical injection molding creates plastic or silicone parts for medical procedures, including prosthetic limbs and surgical tools. Sterility is crucial throughout the process. The technology has led to significant advancements in prosthetic technology and surgical tools.
Medical injection molding is a method used in creating plastic or silicone parts used for medical procedures. Plastic or silicone parts can include tools for surgery or parts that will be placed inside the human body. The medical injection molding process differs from typical plastic injection molding, due to the medical element in the process.
Each step of the medical injection molding process must be performed with absolute sterility. A clean environment must be created from the beginning of the process through the final application of the part. This is especially true in applications where the molded part is intended for use in a human body to enhance or replace the function of a body part.
The use of silicone or plastic parts made by medical injection molding has become increasingly popular in severed or amputated limb applications. It enables people designing the latest prosthetic tools to use the materials that allow for the most realistic function in prosthetic use. Moving fingers, twisting wrists, or ankle joints that bend while running are some of the more recent improvements in prosthetic technology, mainly through the use of plastics and silicones made through the injection molding process. Stamped parts allow for the exact sizing and specification needed for these types of parts.
Medical injection molding is also used to create perfectly shaped tool ends that can be used in medical applications, such as internal surgery tools. Clamp ends and almost any tool that is not used for precision cutting can be made from these types of parts, as long as they have been handled with the utmost sense of sterility and medical duty. If the tool has been contaminated during the making or packaging or shipping process, it can no longer be used for medical purposes.
Thanks to medical injection molding, doctors and surgeons are able to expertly remove entire limbs and then later implant a new prosthesis on the body and make it more functional than previously imagined in the medical community. Having a plastic and metal arm grafted where an arm was lost, and having that arm act almost like the arm that was removed, is a direct result of advances made in both the medical and plastics and thermoplastics fields. These advances lead many to believe that things like silicone hearts are on the horizon.
