Problems solved by technology

However, such surgical instruments tend to create tunnels that are not truly circular, or worse, can create tunnels along paths that diverge from the intended trajectory, and thus may not be anatomical and / or may cause damage to the nerve. damage to vascular structures

Abstract

A hollow retrograde reamer that is adjustable to produce tunnels of various diameters. The hollow retrograde reamer substantially reduces the risk of tunnel misposition and / or misalignment and can be adjusted to produce a range of tunnel diameters, allowing for reduced inventory levels for surgical cases.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Patent Application No. 61 / 733,479, filed December 5, 2012, entitled "SURGICAL INSTRUMENT," and U.S. Provisional Patent Application No. 61 / 757,843, filed January 29, 2013, entitled "SURGICAL INSTRUMENT" and the benefit of priority to U.S. Provisional Patent Application No. 61 / 805,578, filed March 27, 2013, entitled "RETRO GUIDEWIRE REAMER." technical field [0003] The present invention relates generally to surgical instruments and, more particularly, to surgical instruments having at least one cutting member, such as a rotatable blade for use in retrograde cutting of bone. Background technique [0004] Some surgeons have used a retrograde approach to perform anterior cruciate ligament (ACL) surgery to create a femoral ACL tunnel (ie, "total internal ACL reconstruction"). like figure 1 As shown in , this approach typically entails surgery to drill the tunnel 102 in a retrograde...
