AN IMPROVED ADJUSTABLE LIFT SYSTEM FOR MINIMAL INCISION SURGERIES

摘要

The invention discloses an improved adjustable lift system for minimal incision surgeries. This is a surgical instrument for improving the exposure of surgical structures while performing surgeries through a minimal incision approach like ministernotomy in cardiac surgery. The lifting system consists of one hook system (1) and a retractor instrument (2). The hook is a multi perforated flat plate (11) which is fixed onto a metal bar on the operating table. The retractor instrument (2) has a shaft (3) i.e. circular in profile and the diameter tapers to the angle end (6) so as to reduce the profile and the triangular blade (4) which is placed underneath the undivided sternum is placed at an angle (6) to the shaft. The shaft has a L shaped hook (8) riveted to it and is used to hitch the pericardium with sutures and act as a stay for the sutures to be hitched. A circular hoop (9) in the mid position increases the surgeons grip while raising the retractor to the hook. Flanged knob (5) fits the instrument (2) to the perforation in the hook (1) in a lock and key fashion. Fig. 1 and 2.
