Abstract

A surgical tool (8) includes a main unit (21) and a first rigid sheath (11a). The main unit (21) comprises an inner tube (9) received inside the outer tube (10). The first rigid sheath (11a) removably receives the main unit (21) and by means of the first connector part (38) of the main unit (21) and the second connector part of the rigid sheath (11a) (39) and connected to the main unit (21). When the first connector part (38) is decoupled from the second connector part (39), the first rigid sheath (11a) can be completely removed from the main unit (21). A different rigid sheath (11b) having a shape different from that of the first rigid sheath (11a) can then be removably attached to said main unit (21) instead of the first rigid sheath (11a) . A surgical tool kit includes a plurality of rigid sheaths (11a-f) of different shapes and the ability to be removably attachable to a main unit (21).

Description

Background technique [0001] The present disclosure relates to improved surgical tools, methods of performing surgical procedures utilizing surgical tool assemblies, and surgical tool kits. In particular, the present disclosure relates to surgical tool assemblies that can be used to scrape, cut, cut, grind, and / or remove tissue, bone, and / or other bodily matter utilizing rigid sheaths having different shapes. [0002] Surgical devices for scraping, cutting, cutting, grinding and / or removing tissue, bone, and / or other bodily matter are known. Such surgical devices may include a cutting surface, such as a rotating blade, disposed on an elongated inner tube that rotates within an elongated outer tube having a cutting window. Together the inner and outer tubes form the surgical cutting blade. Typically, the elongated outer tube includes a distal end that defines an opening or cutting window that exposes the cutting surface of the inner tube (located at the distal end of the inner...
