Medical instrument with mechanical trigger mechanism for safe articulation
A recently granted patent (Publication Number: US11992236B2) discloses a novel medical instrument designed with a hollow shaft that includes an actuating unit at the proximal end and an instrument tip at the distal end. The instrument can be controlled through an actuating element within the shaft, which is connected to the actuating unit. The instrument tip is capable of pivoting relative to the shaft's longitudinal axis via a joint mechanism. This joint mechanism utilizes steering wires inside the hollow shaft tube to enable movement of the instrument tip in response to the proximal-side drive. Importantly, the patent emphasizes a trigger mechanism that allows for the relaxation of the steering wires independently of the actuation of the proximal-side drive, ensuring the instrument tip remains in a fixed position between movements without the need for a locking mechanism. The trigger mechanism, designed as a mechanical clamping mechanism, enables the simultaneous relaxation of all steering wires, enhancing the instrument's functionality.
Furthermore, the patent highlights the inclusion of a separate drive for each steering wire within the trigger mechanism, providing a more precise control over the movement of the instrument tip. In case of a failure of the proximal-side drive, the mechanical trigger mechanism ensures the free movement of the pivoting members, allowing for continued operation of the instrument. Additionally, the trigger mechanism's design allows for the displacement of the hollow shaft tube to relax the steering wires, further enhancing the instrument's versatility and ease of use. Overall, the patented medical instrument offers a unique combination of features that improve the control and functionality of medical procedures, making it a valuable innovation in the field of medical instruments.
