Laparoscopic instrument and trocar system and related surgical method

摘要

Laparoscopic instruments and cannulas are provided for performing laparoscopic procedures entirely through the umbilicus. Generally S-shaped laparoscopic instruments placed through the C-shaped trocar sleeves or through the cannula and instrument holder unit provide markedly improved degrees of instruments' freedom during trans-umbilical laparoscopic procedures.

主权项

1. A method of laparoscopic surgery comprising the steps of:
grasping an instrument holder assembly having an insertion configuration for at least partial insertion of said holder assembly through an incision in a patient for at least partial insertion of said holder assembly into a patient cavity, and an in use configuration for use of said instrument holder assembly for access to said patient cavity, said instrument holder assembly radially compressed into a compact configuration for the insertion of said holder assembly at least partially through the incision in a patient, the radially compressed compacted instrument holder assembly defining an outer peripheral surface; and
inserting said radially compressed compacted instrument holder assembly at least partially through said incision,wherein grasping said radially compressed compacted instrument holder assembly includes retaining the outer peripheral surface of the radially compressed compacted instrument holder assembly via a grasping instrument that includes a pair of tongs having:a pair of handles pivotably joined to each other, the handles defining proximal and distal ends; anda pair of cylindrically shaped jaw elements disposed one on each of the distal ends of the handles and configured to enable retention of said radially compressed compacted instrument holder assembly,wherein retaining the radially compressed compacted instrument holder assembly via the pair of tongs includes grasping the radially compressed compacted instrument holder assembly between the cylindrically shaped jaw elements.
