AI Technical Summary
Technical Problem
Current biopsy devices face challenges in ergonomic design, requiring two-handed operation, difficulty in preparing and activating the device, potential for accidental firing, and inconsistent user activation due to ergonomic factors and button placement.
Method used
A biopsy device with an ergonomic design allowing one-handed operation, featuring a two-stage firing sequence using distinct buttons and structural components that ensure sequential firing of inner and outer cannulas, integrated buttons for improved grip, and noise-reducing features.
Benefits of technology
Enhances user comfort and safety by enabling one-handed preparation and activation, reducing accidental firing, and ensuring consistent operation, while minimizing noise and improving targeting accuracy.

Abstract
The biopsy device includes an elongated housing that houses a stylet hub and a cannula hub. Each of the stylet hub and the cannula hub is movable between a proximal ready-to-operate position and a distal fired-out position. Each of the stylet hub and the cannula hub has a strike configured to hold its respective hub in its proximal ready-to-operate position. A ready-to-operate member is movably mounted in the housing and is configured to move the stylet hub and the cannula hub to their respective proximal ready-to-operate positions. The housing includes a first flexible wall portion, and when the stylet hub is in the distal fired-out position and the cannula hub is in the proximal ready-to-operate position, a portion of the stylet hub is positioned between the cannula strike and the first flexible wall portion, allowing the cannula hub to be released from its proximal ready-to-operate position by the action of the first flexible wall portion.
