A new device simplifies suturing in minimally invasive surgeries like natural orifice transluminal endoscopic (NOTES) and single incisional laparoscopic surgery (SILS). This innovation addresses challenges in these procedures, potentially improving surgical outcomes.
Area of Science:
- Minimally Invasive Surgery
- Surgical Instrumentation
Background:
- Natural orifice transluminal endoscopic (NOTES) and single incisional laparoscopic surgery (SILS) are increasingly important surgical techniques.
- Suturing and knot-tying are difficult in NOTES and SILS due to limited workspace and instrument constraints.
Purpose of the Study:
- To develop an automated device for simplifying suture passing in NOTES and SILS.
- To overcome the challenges of intracorporeal suturing in minimally invasive procedures.
Main Methods:
- An intracorporeal suture-passing device with two manipulator arms was designed.
- The device can deploy sutures around ducts up to 7 mm in diameter through a 3 mm inner diameter trocar.
Main Results:
- The device's mechanism was validated in 15 trials on a phantom tube.
- The average operating time for passing the suture was 34.55 ± 4.55 seconds.
Conclusions:
- The proposed device automates suture passing, addressing a key challenge in NOTES and SILS.
- Further clinical evaluation of prototypes is expected to confirm the device's efficacy.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
