Abstract
Various embodiments of a suture tensionometer for measuring a tensile force applied to a surgical suture are disclosed herein.
Claims13
A device, comprising:
- a needle driver including a first member and a second member joined at a connection, the needle driver being operable to capture a tensioning element;
- and
- a tensionometer assembly in operative association with the needle driver, the tensionometer assembly including:
- a plurality of force-sensing elements, each positioned along the first member and including:
- a first force-sensing element positioned at a first longitudinal location along the first member distal of the connection;
- a second force-sensing element positioned at a second longitudinal location along the first member coincident with the connection;
- and
- a third force-sensing element positioned at a third longitudinal location along the first member proximal of the connection;
- the plurality of force-sensing elements collectively measuring a lateral force component acting on the first member perpendicular to a longitudinal axis collectively defined by the first member and the second member, wherein the second force-sensing element serves as a reference between the first force-sensing element and the third force-sensing element.

A device, comprising:
- a tensionometer assembly in operative association with a needle driver, the tensionometer assembly including:
- a plurality of force-sensing elements, each of the plurality of force-sending elements being positionable along a first member of the needle driver and including:
- a first force-sensing element positioned at a first longitudinal location along the first member distal of a connection between the first member and a second member of the needle driver;
- a second force-sensing element positioned at a second longitudinal location along the first member coincident with the connection;
- and
- a third force-sensing element positioned at a third longitudinal location along the first member proximal of the connection;
- the plurality of force-sensing elements collectively measuring a lateral force component acting on the first member perpendicular to a longitudinal axis collectively defined by the first member and the second member, wherein the second force-sensing element serves as a reference between the first force-sensing element and the third force-sensing element.
