Abstract
A method of manufacturing a surgical instrument or prosthesis and an injection moulded surgical instrument or prosthesis are described. A first material is injected into a first mould to form an interim component. A second material is injected into a second mould containing at least part of the interim component to form the surgical instrument or prosthesis such that portions of the first and second materials are exposed at the external surface of the surgical instrument or prosthesis. The first and second materials are visually distinct such that at least one exposed portion of the first or second material adjacent to an exposed portion of the other material forms a marking which is visible to a user.
Claims17
A method of manufacturing a surgical instrument or prosthesis, comprising the steps of:
- injecting a first material into a first mold to form an interim component;
- and
- injecting a second material into a second mold containing at least part of the interim component to form the surgical instrument or prosthesis such that portions of the first and second materials are exposed at the external surface of the surgical instrument or prosthesis;
- wherein the first and second materials are visually distinct such that at least one exposed portion of the first or second material adjacent to an exposed portion of the other material forms a marking which is visible to a user.
An injection molded surgical instrument or prosthesis, comprising:
- an injection molded body having an external surface, said external surface comprising at least one exposed first portion formed from a first material in a first injection molding step and at least one exposed second portion formed from a second material in a second injection molding step;
- wherein the first and second materials are visually distinct such that at least one of said first and second portions forms a marking which is visible to a user.
