Surgical securement system and apparatus

摘要

A surgical securement apparatus for selectively securing one or more ends of a cord while allowing adjustments in the tension or a full release of the cord intermittently after a prolonged period of time. A surgical securement and marking system utilizing one or more surgical securement apparatus that are color-coded to convey information about the associated intercorporeal structures. The surgical securement apparatus can be particularly adapted for use in securing intracorporeal structures such as nerves, blood vessels, and tendons during a surgical procedure. An extender tube connected to the surgical securement apparatus enables securement of intracorporeal structures within the surgical site from outside the surgical site. A threading assembly for use with the surgical securement apparatus that is adapted to facilitate threading of a cord along the length of the surgical securement apparatus.

主权项

1. A surgical securement assembly for securing one or more intracorporeal structures during a surgical procedure, the surgical securement assembly comprising:
a securement cord configured to extend around one or more intracorporeal structures; a surgical securement apparatus, comprising:
a body having a cavity positioned therein;a plunger comprising a plunger lumen, the plunger slidably disposed within the cavity of the body;a biasing spring positioned within the cavity of the body and engaging the plunger to bias the plunger and allow for releasable engagement of the securement cord;a connector extending outwardly from the body; andan extender tube coupled to the connector, the extender tube extending between a proximal end directly coupled to the connector and a distal end, the distal end distally offset from the connector,wherein the distal end of the extender tube is disposable adjacent one or more intracorporeal structures and the body is disposable at a predetermined displacement from the distal end of the extender tube such that the body can remain outside the surgical site when the distal end of the extender tube is within the surgical site;and wherein the extender tube is configured to accommodate a portion of the securement cord therein such that the distal end of the extender tube draws opposite portions of the securement cord together to form a loop of the securement cord, such that the extender tube closes the loop and provides tension on the loop at a location adjacent an intracorporeal structure;and wherein the extender tube is flexible along its length such that the body is displaceable outside the surgical site while the distal end of the extender tube remains adjacent an intracorporeal structure and such that a location wherein the extender tube closes the loop and provides tension on the loop is flexibly offset from a location wherein the plunger engages the securement cord; and a threading assembly having a base and a threading loop comprising a suture material for facilitating threading of the securement cord through each of a connector lumen, a lumen of the surgical securement apparatus, and the plunger lumen, wherein the base engages tails of the threading loop adjacent free ends of the threading loop tails, and wherein each of the connector lumen, the lumen of the surgical securement apparatus, and the plunger lumen comprises dimensions sufficient for passage of both the threading loop and the securement cord when the securement cord is threaded through the threading loop and folded over.
