A surgical training device for the practice of surgical techniques
comprises a base and a face wall extending from a side of said base such
to block direct visualisation of the operation area from the normal
external position of the eyes of the trainee using the device. The face
wall comprises a front wall and an upper wall. The front wall is extended
upwardly from the base; the upper wall is then extended upwardly and
inwardly from the front wall. A flexible membrane is stretched on upper
wall and has at least two portals such that adaptors can be inserted on
flexible membrane. The adaptors are further fitted with stoppers to
prevent adaptors been pulled out from the membrane during training. The
surgical instruments can pass through the openings of adaptors to
manipulate simulated tissue or another operable structure on the base. A
plain spherical bearing set, including a bearing seat and a plain
spherical bearing, is also installed on said upper wall. The bearing seat
has a bearing hole to interference fit with plain spherical hearing and
two bolt holes to hold bearing seat on upper wall such that a camera
handle can pass through plain spherical bearing to catch the image on
base.
