STABILIZER FOR SURGERY

摘要

A stabilizer is used to immobilize a portion of the heart or other organ to facilitate a surgical procedure such as anastomosis. The stabilizer comprise s two, C-shaped, organ wall-contacting elements (12, 14), hinged together so that they can form a continuous loop. The hinge allows the C-shaped elements to be separated so that, after surgery in which a tubular graft connected to the organ extends through the loop, the stabilizer can be released from the graft. The C-shaped elements are connected to a stem which consists of two lockably articulating parts (30, 36), one of which is immediately connected to one of the C-shaped elements and aligned with the hinge axis. A spring-loade d sleeve (32), surrounding the last-mentioned part of the stem, has pins (76, 78) which engage recesses in the C-shaped parts to lock them in the closed condition, while allowing them to be opened quickly by manipulation of the sleeve. Removable, disposable pads (92) form the organ wall-contacting surfaces. An optional light carrier (102, 104) provides illumination, and ports (114) are provided in one of the C-shaped elements for suction and/or irrigation.
