What You Should Do While There: Take a moment to escape the city life for a day and explore the Toronto islands. Easily hop a ferry and head to the collection of eight islands. They offer a welcoming green atmosphere beyond the cityscape that is Toronto. There are no cars on the island, so enjoy a nice stroll or bike.
Self-Retaining Retractors. Retractors are used to hold an incision or wound open while a surgeon works. The retractor could also be used to hold tissues or organs out of the way during a surgery. Self-retaining retractors allow hands free operation during a surgery. Retractors with opposable blades which use a screw, ratchet or clamp to hold the tissue apart by themselves are called self-retaining retractors.
A retractor is a surgical instrument by which a surgeon can either actively separate the edges of a surgical incision or wound, or can hold back underlying organs and tissues, so that body parts under the incision may be accessed. Retractors are used for holding the incision open to provide exposure to thesurgical site.
