However, problems unique to endoscopes have emerged as their use has spread. For example, in laparoscopy the need to inflate the abdomen with gas can lead to discomfort afterward, sometimes resulting in pain for days after the procedure. Devices called abdominal retractors allow an insert to be placed on the skin above the site to be examined, lifting up the abdominal wall to create a space in which the surgeon can work. Physicians hope this in some cases will replace the need for inflating the operating site with gas and hence will allow quicker recoveries with less pain.

Repeated poor ergonomic posture can be a risk factor for work-related musculoskeletal injuries to the surgeons and their assistants [42]. In a survey-based study, it has been shown that 44–66% of adult reconstruction surgeons surveyed have had a work-related injury, with 10–27% requiring surgery [43,44]. Of these, neck injuries typically have one of the highest incidences [43,44]. Robotic technologies have been introduced into the operating rooms to assist surgeons with ergonomically challenging surgical tasks. These technologies include elements that can reduce the physical stress on the surgeon’s neck, such as heads-up displays to visualize the surgical case. The use of self-retaining retractors results in less soft tissue retraction during a robotic procedure, which may also reduce ergonomic risks to OR nurses and assistants. With the use of robotic technology, less physical work and more ergonomic health-friendly postures are required during the performance of TKA procedures which may reflect positively on the long-term physical health of the surgical staff. Initial findings have been reported at conferences; however, true evaluation of this potential value is needed by future studies.
Devices for minimally-invasive microdiscectomy: current status and future prospects

In real practice, the surgeon may frequently encounter cases requiring more extensive surgical exposure. For more available space, expandable tubular retractors such as X-tube or QUADRANT Retractor System (Medtronic Sofamor Danek, Memphis, TN) can be used [52–54]. Use of elliptical or rectangular shape tubular retractor may reduce the surgical invasiveness without increasing surgical difficulty. Some authors reported that the use of a rectangular tubular retractor significantly reduced the muscle resection and postoperative pain [55].
