AI Technical Summary
Existing surgical robots have unreasonable guidewire clamping structures, resulting in insufficient or excessive clamping force that causes guidewire deformation and damage. They also lack real-time force feedback and are inconvenient to install and remove guidewires.
A force feedback guide wire propulsion mechanism was designed, including a mounting frame, a rotating seat, a support seat, a separating arm, a clamping adjuster, a connecting arm, a rotary drive device, and a separating drive mechanism. Through the cooperation of the main clamping wheel and the auxiliary clamping wheel, the guide wire is accurately clamped and axial force feedback is achieved. Polyurethane rollers are used to reduce guide wire damage. The structure is simple and reasonable.
It achieves effective clamping and axial force feedback of the guidewire, avoids guidewire deformation and damage, and is easy to assemble and disassemble, thus improving the operational accuracy and safety of the guidewire during surgery.
