Finochietto Rib Spreader 38x44mm, 135mm

Clinical Application

Designed for exposure of the thoracic cavity, this Finochietto-style rib spreader provides controlled separation of ribs during thoracotomy, lobectomy, cardiac access, and other intrathoracic procedures. The instrument maintains a stable operative field to facilitate visualization and instrumentation of the lungs, heart, pleura, and mediastinum, reducing the need for manual retraction and allowing the surgical team to operate with both hands free.

Design & Configuration

The instrument uses a traditional Finochietto rack-and-pinion ratchet that permits incremental, self-retaining spread and precise adjustment of blade distance. The opposing blades are contoured to conform to rib curvature, distributing retraction forces across the rib surface to minimize focal pressure while maximizing exposure. The 38x44 mm dimension identifies the blade contact geometry, and the 135 mm length provides leverage for controlled opening while keeping the frame compact for operative ergonomics.
