Embodiment Construction

[0041] Disclosed herein are coupling devices and associated methods, for example, for coupling surgical instruments to navigation arrays or other components. The linkage reduces or eliminates movement between the instrument and the navigation array, thereby improving navigation accuracy. The coupling device is quick and easy to use, thereby reducing or eliminating the need for additional steps or additional tools to attach or detach the instrument from the coupling device. In some embodiments, the single step of inserting the instrument into the coupling automatically locks the instrument within the coupling in a freely switchable manner. The coupling means may include features for consistently attaching an instrument thereto in a known or predetermined position and / or orientation.

[0042] Certain exemplary embodiments will now be described to provide a general understanding of the principles of the structure, function, manufacture and use of the devices and methods disclose...

Abstract

Coupling devices and related methods are disclosed herein, e.g., for coupling a surgical instrument to a navigation array or other component. The coupling device can reduce or eliminate movement between the instrument and the navigation array, improving navigation precision. The coupling device can be quick and easy to use, reducing or eliminating the need for extra steps or additional tools to attach or detach the instrument from the coupling device. In some embodiments, the single step of inserting an instrument into the coupling device can automatically lock the instrument within the coupling device in a toggle-free manner. The coupling device can include features for consistently attaching instruments thereto at a known or predetermined location and / or orientation.

Description

technical field [0001] Coupling devices and associated methods for surgical instruments, eg, for coupling surgical instruments to navigation arrays or other components, are disclosed herein. Background technique [0002] Increasingly, surgery involves the navigation or tracking of instruments used during the surgical procedure. Surgical navigation can help avoid fragile nerve or vascular structures when moving implants or instruments within a patient. For example, in spinal surgery, surgical navigation systems may be used during screw insertion, disc removal, bone preparation, and other steps of the surgery. The use of surgical navigation systems also reduces the amount of X-ray exposure to patients and operating room staff. [0003] A typical navigation system includes an array of markers attached to the surgical instrument, an imaging system that captures images of the surgical field, and a controller that detects the markers in the captured images and tracks the movemen...
