Soft tissues filling: not so minimally invasive

Soft tissue damage after minimally invasive THA

BACKGROUND AND PURPOSE Minimally invasive surgery (MIS) for hip replacement is thought to minimize soft tissue damage. We determined the damage caused by 4 different MIS approaches as compared to a conventional lateral transgluteal approach. METHODS 5 surgeons each performed a total hip arthroplasty on 5 fresh frozen cadaver hips, using either a MIS anterior, MIS anterolateral, MIS 2-incision...

Vacuum-assisted minimally invasive biopsy of soft-tissue tumors.

BACKGROUND Although exact histological characterization of soft-tissue tumors is essential for determining the appropriate therapy, the quality of the histological assessment is often limited by the size of the tissue samples. Incisional biopsy and core needle biopsy have been the most effective techniques for obtaining tissue samples from soft-tissue tumors. This study was performed to investi...

Vacuum-Assisted Minimally Invasive Biopsy of Soft-Tissue Tumors

A bioinspired soft manipulator for minimally invasive surgery.

This paper introduces a novel, bioinspired manipulator for minimally invasive surgery (MIS). The manipulator is entirely composed of soft materials, and it has been designed to provide similar motion capabilities as the octopus's arm in order to reach the surgical target while exploiting its whole length to actively interact with the biological structures. The manipulator is composed of two ide...

A soft pop-up proprioceptive actuator for minimally invasive surgery

INTRODUCTION Surgical robots and miniaturized smart instruments have been developed to overcome limitations of current tools and further reduce invasiveness of surgical procedures [1][2]. This miniaturization effort, as well as the development of more flexible instruments that can navigate the body following complex anatomical paths toward the surgical target, often leads to the loss of sensory...
