Endoluminal introducer

Abstract

An introducer for use during endoscopic procedures provides insufflation, washing, and aspiration functions, and provides for the protection of the endoluminal surface during laparoscopic examination of an anastomosis or suture line following low anterior resection of the bowel. The introducer may be designed for the insertion of an endoscope capable of white light and/or near infra-red fluorescence imaging into the rectum for analysis of an anastomosis following low anterior resection of the bowel.

Description

[0001] This application claims the benefit of priority of US Provisional Application No. 61 / 745,682, filed December 24, 2012, the disclosure of which is incorporated herein by reference. technical field [0002] The present disclosure relates to an intraluminal introducer, and more particularly, to an introducer for inserting an endoscope capable of white light and / or near-infrared fluorescence imaging. Background technique [0003] Lower anterior resection (LAR) is a common rectal surgical procedure for rectal cancer. Such surgical procedures are increasingly, but not exclusively, performed using minimally invasive surgical (MIS) techniques. With the advent of high-definition (HD) laparoscopy, surgical visualization during MIS has achieved new performance standards and has improved the ability of rectal surgeons to assess and navigate the surgical site. This endoscope is typically used in conjunction with a high-definition camera system to produce real-time video images th...

Problems solved by technology

However, since laparoscopes are intended solely for intraperitoneal visualization during MIS, and separate instruments are used for insufflation, washing, and aspiration during such surgical procedures, laparoscopes are typically not equipped to provide such functionality.
