Abstract: According to an aspect of the invention there is provided a mouldable material carrier for use in producing an impression of a surgical site comprising: a base having a channel passing through the base between an inlet and an outlet; and a securing portion configured to secure a flexible sheet to the base around the outlet to cover the outlet such that, when mouldable material is urged through the inlet, the mouldable material is extruded out of the outlet and contained within a volume defined by the flexible sheet and the base, such that when the mouldable material carrier is urged against a surgical site, the mouldable material within the volume forms an impression of the surgical site without making contact with the surgical site.

Abstract: A surgical guide production apparatus and accessories are provided to simplify the process of using the production apparatus within the surgical environment. A cutting attachment is provided for use on a surgical guide production apparatus. The cutting attachment comprises a cutting element, a connector for connecting the cutting element to a drive mechanism of the surgical guide production apparatus so that the cutting element can be driven by the drive mechanism to modify an impression of a surgical site to produce a surgical guide, and a protective barrier. The protective barrier is configured to be positioned around the cutting element to surround a cutting area to help prevent contaminants from entering or leaving the cutting area during modification of the impression.

Abstract: There is disclosed a sagittal saw blade mount and corresponding sagittal saw blade. The blade mount is configured to rotationally oscillate along a plane of motion about an axis of rotation which passes through the blade mount crossing the plane of motion at a point of rotation. The blade mount comprises a securing portion comprising two securing faces passing through the plane of motion and a locking member configured to urge a blade towards the securing portion in a first direction parallel to the plane of motion, thereby securing the blade between the locking member and the securing faces. The two securing faces are angled such that the planes of the securing faces intersect with each other and with the plane of motion at a point of intersection which is positioned such that the point of rotation lies between the point of intersection and the securing portion.
