Surgical head fixation apparatus with adjustable clamping mechanisms
The patent US11992442B2 describes a surgical head fixation apparatus designed to securely hold a patient's head during medical procedures. The apparatus features a head holder supported by an articulated link unit, which consists of multiple link sections and at least one link-shaped clamping operation unit. This clamping unit includes an operating lever and multiple pivot axes, enabling the apparatus to switch between various states: a clamped state that locks movements on two axes, an unclamped state that allows free movement, and a ready-to-clamp state that locks one axis while allowing movement on the others. The operating lever can be manipulated to transition between these states, enhancing the apparatus's versatility and ease of use.
Further details reveal that the link-shaped clamping operation unit comprises joint portions with cylindrical components and a pull-in shaft that connects them. The design incorporates a lever link mechanism that facilitates simultaneous clamping of the joint portions. Additionally, the apparatus includes a slide lock mechanism to secure the operating lever in place during clamping. The articulated link unit can consist of multiple clamping operation units, providing further adaptability for different surgical scenarios. Overall, this innovative design aims to improve the efficiency and safety of head fixation in surgical settings.
