摘要:
Devices and methods provided for joint arthroscopy contemplate and enable the provision of patient specific instruments (PSI). The devices and anatomical features of a patient are rendered adjustable by the provision of guide elements and feature to account for and enable repositioning of the anatomical features during surgery. Where the joint arthroscopy involves ankle arthroplasty, a PSI system includes a tibial PSI operable to be coupled to a tibia and a talar PSI operable to be coupled to a talus. Pins pass through the tibial PSI into the tibia and through the talar PSI into the talus. The tibia and talus are aligned based on the tibial PSI, the talar PSI, the pins, and optionally a connection guide operable to receive, or be coupled to, the pins. The tibial PSI and the talar PSI allow for the transfer of pre-operative planning to intra-operative procedures.

A closure system, assembly and attended method for closing and opening in the tissue of the patient includes first and second closure members each including a biased construction operative for disposition of the closure members into an out of retracted and expanded orientations. A connector is disposed in interconnecting relation with the closure members and structured to establish at least a partial spacing there between. The biased construction and the interconnection of the closure members facilitate con current disposition of the closure members with one another into and through an introductory instrument as well as independent and successive disposition of the first and second closure members into a closing relation to the tissue opening upon exiting the introductory instrument.
摘要:
The present invention concerns hybrid manual-robotic system for supporting and moving a surgical instrument having active main structure (100) that comprises: a) a base (2) for attachment to an operating table having an operating surface (150); b) a hexahedral-shape frame (3), which shape is formed from a first (5, 5′) and second (4, 4′) pair of opposing parallelograms and opposing proximal (6′) and distal (6) rectangles, which frame (3) is formed by at least seven links (7, 8, 9, 10, 11, 12, 13, 22, 23) connected by revolute joints (14, 15, 16, 17, 18, 19, 20, 26, 27, 109), whereby a) a pair of parallel base links (7, 13) of the proximal rectangle (6′) is coupled to the base (2) by two revolute joints (116, 117), and are configured to lie and remain essentially perpendicular to the plane of the 10 operating surface (150) and to revolve around their longitudinal axes that coincide with the axes of revolution of joints (116, 117), whereby b) said revolute joints are configured to allow the hexahedral frame (3) to freely adopt a cube, or parallelepiped restricted by said perpendicular coupling; and whereby c) the distal rectangle (6) is coupled through a transmission means (200) to said instrument.
