Knots and Method and Device for Generating the Same

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a novel surgical knot, along with a method and device for automatically creating it. The knot is designed particularly for medical applications such as suturing wounds, and is optimally suited for laparoscopic and/or endoscopic surgery. The invention includes a detailed process for forming the knot, and also provides specialized devices that automate and standardize its formation, increasing precision and repeatability.

Use CasesContent extracted from patent full text and abstract with AI.

• Closure of wounds during minimally invasive (laparoscopic/endoscopic) surgeries
• Manual or automated tying of surgical sutures in open or minimally invasive procedures
• Development of surgical robots or devices for automated knot tying
• Medical training and simulation devices for practicing safe, reliable knot techniques

BenefitsContent extracted from patent full text and abstract with AI.

• Allows secure closure of surgical wounds with high knot strength and reliability
• Enables automation, which improves consistency and reduces human error in knot tying, particularly in minimally invasive surgery
• Separates wound approximation force from knot fixation force, increasing surgical control and safety
• Facilitates faster and more standardized suturing, potentially reducing surgery time
• Can be integrated into various surgical devices, making it adaptable for complex procedures

Patent Abstract

The invention relates to a surgical thread with two free ends, one free end forming a proximal end and the other forming a distal end, then forming two turns with the distal free end, lying in the direction of the proximal free end, such as to pass around the surgical thread twice in the direction of the proximal free end, forming a bow with the distal free end and passing the bow through both loops formed by the two turns such as to form a first noose on the side of the two loops away from the proximal free end such that the distal free end as a result is on the side of the two loops facing the proximal end and points in the direction of the proximal free end and then tightening the knot by exerting a tensile force between the first noose and the proximal free end of the thread.
