AIM To design a miniature magnetically anchored and controlled camera system to reduce the number of trocars which are required for laparoscopy. METHODS The system consists of a miniature magnetically anchored camera with a 30° downward angle, an external magnetically anchored unit, and a vision output device. The camera weighs 12 g, measures Φ10.5 mm ×(More)
BACKGROUND Magnetic anchored surgical instruments (MASI), relying on magnetic force, can break through the limitations of the single port approach in dexterity. Individual characteristic abdominal wall thickness (ICAWT) deeply influences magnetic force that determines the safety of MASI. The purpose of this study was to research the abdominal wall(More)
BACKGROUND The resection and reconstruction of large vessels, including the portal vein, are frequently needed in tumor resection. Warm ischemia before reconstruction might have deleterious effects on the function of some vital organs and therefore, how to reconstruct the vessels quickly after resection is extremely important. The present study was to(More)
Using a decellularized liver matrix (DLM) to reengineer liver tissue is a promising therapy for end-stage liver disease. However, the limited supply of donor organs still hampers its potential clinical application, while a xenogenic decellularized matrix may bring a risk of zoonosis and immunological rejection. Therefore, an appropriate alternative scaffold(More)
