Endoscopic Procedures III: Video Capsule Endoscopy

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Area of Science:

Surgical Innovation
Gastrointestinal Surgery
Medical Device Design

Background:

Conventional surgical staplers for bowel anastomosis have limitations.
A need exists for reusable devices to improve efficiency and reduce waste.
Current methods may not always ensure optimal contact between intestinal walls.

Purpose of the Study:

To present the design and prototype of a novel egzoluminal circular surgical stapler.
To evaluate the preliminary in vivo performance of this device for end-to-end intestinal anastomosis.
To assess the feasibility of a reusable surgical stapler in a clinical setting.

Main Methods:

Design and development of an egzoluminal circular surgical stapler with a unique kinematic operation.
Prototype creation and in vivo testing in animal models.
Evaluation of staple placement outside the intestinal lumen for direct mucosal contact.

Main Results:

Successful in vivo testing of the egzoluminal circular surgical stapler in animals.
Demonstrated feasibility of end-to-end anastomosis with staples placed externally.
The device's design facilitates direct contact between intestinal walls and the mucous membrane.

Conclusions:

The developed egzoluminal circular surgical stapler is a viable and applicable device for end-to-end bowel anastomosis.
The novel design and reusable nature address key needs in gastrointestinal surgery.
Successful animal trials indicate strong potential for clinical practice, supported by patent application P 386369.
