摘要：
A sphincter sizing instrument includes a body that defines a lumen and a shaft that longitudinally translates through the lumen relative to the body. The body includes opposing proximal and distal ends. The distal end includes a first magnetic coupling feature and a first mechanical coupling feature. The shaft includes opposing proximal and distal ends and a coupler coupled with the distal end. The coupler includes a second magnetic coupling feature and a second mechanical coupling feature. The second magnetic coupling feature is configured to attract and couple with the first magnetic coupling feature to form a magnetic connection. The second mechanical coupling feature is configured to couple with the first mechanical coupling feature to form a mechanical connection.
