US 12,533,122 B2 · Suturing apparatus and method

Abstract

Disclosed embodiments include apparatuses, systems, and methods for driving a needle to facilitate suturing, such as may be performed in a surgical anastomosis procedure. In an illustrative embodiment, an apparatus includes a frame. First and second rollers are rotatably mounted parallel with each other in the frame and are configured to engage therebetween a shaft of a needle formed in a helical shape. The first and second rollers are configured to counter-rotate. The needle is revolvable eccentrically around the first roller responsive to counter-rotation of the first and second rollers. A drive mechanism is secured to the frame and is configured to move the frame.

Dependent claims

A method comprising:

engaging opposing sides of a shaft of a needle between parallel faces of first and second rollers, wherein the needle is formed in a helical shape and configured to draw a filament from its trailing end;
counter-rotating the first and second rollers to cause the helically shaped needle to revolve eccentrically around the first roller positioned adjacent to an object to cause a leading end of the needle to pierce the object adjacent to an outer face of the first roller;
and
translating the rollers along an edge of the object, wherein counter-rotating the first and second rollers and translating the first and second rollers causes the needle to draw the filament to suture the edge of the object adjacent the outer face of the first roller.
