Medical device

摘要

This invention generally relates to a medical device assembly for facilitating a sealed working channel into a pressurized body cavity, and methods of use thereof. In certain embodiments, devices of the invention include a hollow body that is splittable along its length and being configured to move between an open configuration for operably coupling with a surgical instrument and a closed configuration, in which in the closed configuration, the device provides a seal that prevents gas leakage from an incision site of a body cavity while the instrument is in the body cavity.

主权项

1. A device for facilitating creation of a sealed channel into a body cavity, the device comprising:
a hollow body having first and second portions hingedly connected to each other, the hollow body splittable along its length and configured to move between an open configuration and a closed configuration, the hollow body defining a lumen extending between open proximal and distal ends in the closed configuration, the hollow body configured to sealingly engage a surgical instrument extending through the open proximal end of the hollow body to prevent gas leakage from a pressurized body cavity through the hollow body in the closed configuration and allowing gas leakage in the closed configuration in the absence of the surgical instrument; and a locking mechanism for holding the hollow body in the closed configuration, the locking mechanism having a spring that biases the hollow body toward the closed configuration.
