Single-use Balloon Gastric Tube

The Sterile Auxiliary Gastrectomy Device is a specialized, single-use surgical instrument engineered to address two critical challenges in gastric resection procedures: maintaining anastomotic integrity and verifying intraoperative seal quality. Designed explicitly for open or minimally invasive gastrectomies, this device serves a dual purpose to enhance surgical safety and patient outcomes.

Primarily, the device functions as an intraluminal anastomotic support structure. During the creation of a gastrojejunal or esophagojejunal anastomosis, the device is temporarily deployed to stabilize the tissue edges. This internal splinting action provides a firm, uniform backing that facilitates precise suture placement and ensures even tissue approximation. By preventing inadvertent inclusion of the posterior wall and reducing mechanical stress on the freshly joined tissues, it significantly contributes to the technical precision of the anastomosis.

Secondly, the device integrates a leak testing mechanism to perform intraoperative tightness detection. Its engineered design allows for the controlled insufflation of air or instillation of methylene blue dye into the anastomosed segment. This enables the surgical team to immediately identify microscopic leaks or weak points in the staple or suture line under physiological pressure. Detecting and repairing these imperfections in real-time is proven to drastically reduce the incidence of postoperative anastomotic leakage—a severe complication associated with high morbidity and mortality.

Constructed from biocompatible, atraumatic materials and packaged sterile for immediate use, this auxiliary device streamlines the surgical workflow. By combining mechanical support with functional integrity verification, it provides surgeons with a reliable tool to perform gastrectomies with greater confidence and improved safety margins.
