Abstract

A cannula seal assembly with a compatible flexible cannula. The cannula includes a rigid cannula body having proximal and distal body ends. The cannula body is composed of material having a first thickness. A flexible thread extends along at least a portion of the cannula body from the distal body end toward the proximal body end. The thread is composed of material having a second thickness, which is less than a first thickness. The cannula is attachable to a cannula seal assembly. The assembly includes a housing having a primary seal and a secondary seal therein. The assembly has a spacer connected between the primary seal and the secondary seal and a reservoir between the primary seal and the secondary seal.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Patent Application No. 62 / 785,331, filed December 27, 2018, entitled "Cannula Seal Mechanism" and U.S. Provisional Patent Application No., filed December 28, 2018, entitled "Soft-Thread Cannula" Priority and benefit of 62 / 786,085, both applications are hereby incorporated by reference in their entirety. Background technique [0003] 1. technical field [0004] The present invention relates to surgical devices and assemblies, and more particularly, to a cannula seal assembly with a compatible flexible cannula. [0005] 2. related technology [0006] The cannula is used to support arthroscopic or endoscopic procedures by providing access to the surgical site. Due to fluid management issues, the cannula is usually equipped with a seal at the proximal end. The seal restricts fluid flow through the sleeve, but can also help build fluid pressure. Breaking the seal by passing an ...
