AI Technical Summary
Technical Problem
Existing suturing devices occupy a large space in minimally invasive surgery, making them difficult to use effectively in space-constrained applications.
Method used
A suturing device was designed, including an arc-shaped needle track and a drive system. It utilizes a long, flexible component and a pulley mechanism to achieve efficient puncture and suturing of the needle through an arc-shaped path. Combined with a rotatable pulley and a catheter structure, it optimizes space utilization.
Benefits of technology
It enables efficient and compact suturing operations in minimally invasive surgery, reduces the device's footprint in space-constrained environments, and improves operational flexibility and precision.

Abstract
Implementations of methods related to suturing devices are provided. A suturing device includes a housing defining an arcuate needle track having a first end and a second end and a gap between the first end and the second end of the arcuate needle track. The suturing device also includes a drive system to advance an arcuate needle along the arcuate needle track, the drive system including a drive member operably coupled to an elongate flexible member. The elongate flexible member can be reciprocated on at least one support surface that directs the elongate flexible member from a first path laid in a first plane parallel to a centerline of the arcuate needle track to a second path laid in a second plane different from the first plane.
