Suturing is a high-precision task performed at the end of procedures when surgeon fatigue may increase errors, highlighting the need for robot assistance. Previous autonomous suturing works, such as STITCH 1.0 [1], struggle to fully close wounds due to inaccurate needle tracking, thread tangling, an…
Surgical suturing is a high-precision task that impacts patient healing and scarring. Suturing skill varies widely between surgeons, highlighting the need for robot assistance. Previous robot suturing works, such as STITCH 1.0 [1], struggle to fully close wounds due to inaccurate needle tracking and
In this paper, a novel mathematical framework is introduced for modeling deformation behavior of Tendon-Driven Continuum Manipulators (TD-CMs) featuring discontinuous cross-sectional geometries (i.e., having flexural patterns). Leveraging this framework, we also introduce the concept of design space…
In this paper, with the goal of addressing the high early-detection miss rate of colorectal cancer (CRC) polyps during a colonoscopy procedure, we propose the design and fabrication of a unique inflatable vision-based tactile sensing balloon (VTSB). The proposed soft VTSB can readily be integrated w…
A colonoscopy is the most typical method to inspect for colorectal cancer; however, inserting colonoscopes in nonfixed sites, such as the sigmoid colon, requires very skilled insertion techniques. Since the sigmoid colon is one of the most difficult nonfixed sites for insertion, straightening it is
There are two corresponding authors who have contributed to this letter, yet only one of them has been mentioned as the corresponding author in the original letter. As a result, “Ki-Uk Kyung” was added to footnote as a co-corresponding author. The changes have been reflected as follows.
High stiffness is desirable for wire-driven underactuated hyperredundant manipulators used in minimally invasive surgery. However, limited structural stiffness can cause lateral and angular deflections by the lateral force and moment applied to the distal end of the manipulator. This letter proposes
For safety enhancement reasons, passive gravity compensation is widely applied in robotic systems used in minimally invasive surgery (MIS). MIS robotic systems have a remote center of motion (RCM) in which a surgical instrument conducts a fulcrum motion around a point of invasion. RCM mechanisms inc
