Summary
New coaxial instruments offer enhanced control and maneuverability for minimal access surgery. These advanced tools improve dissection and retraction in laparoscopic and thoracoscopic procedures.
Area of Science:
- Surgical instrumentation
- Minimally invasive surgery
Background:
- Traditional instruments in laparoscopic and thoracoscopic surgery have limitations in terms of dexterity and control.
- The need for improved surgical tools to enhance the capabilities of minimal access surgery is well-established.
Purpose of the Study:
- To introduce and evaluate novel coaxial curved and bayonet instruments for enhanced surgical manipulation.
- To assess the advantages of these new instruments in laparoscopic and thoracoscopic operations.
Main Methods:
- Design of new coaxial curved and bayonet instruments with controlled tip articulation.
- Introduction of instruments into peritoneal and thoracic cavities via flexible, reusable metal cannulae.
- Application of instruments in major laparoscopic and thoracoscopic surgical procedures.
Main Results:
- The new coaxial instruments allow for controlled dissection and directional change of the functional tip.
- Effective blunt dissection and lift retraction capabilities were demonstrated.
- Excellent ergonomic properties were confirmed during extensive use in complex surgeries.
- Coaxial instruments showed distinct advantages over traditional straight instruments.
Conclusions:
- The developed coaxial instruments significantly expand the possibilities within minimal access surgery.
- These instruments offer superior control and maneuverability compared to conventional laparoscopic and thoracoscopic tools.
