Verbesserter chirurgischer Wundspreizer.

摘要

Apparatus useful in surgery for holding retractors (10, 70) and other surgical instrumentation in a number of different positions required by a surgeon for the performance of a surgical procedure, including advanced sensing and regulation (72) or retraction pressures (120) and position (124); and incorporating a force amplification method (102, 96, 104, 88) to drive a locking mechanism (84) in the supporting structure (86) that utilizes a constrained, substantially imcompressible, flexible solid material (88) to yield a mechanism that is suitable for clinical use.
