A recently granted patent (Publication Number: US11771441B2) describes a disposable guide device for spinal surgery. The device includes two guide sleeves that extend between a proximal end and a distal end, which are used to guide surgical interventions on a patient's vertebra. The device also includes a plurality of support elements, each with a contact area specifically designed to abut against a virtual surface that reproduces the patient's vertebra in a coupling configuration. The guide sleeves are joined together by at least one junction element, and each guide sleeve has an auxiliary sleeve that extends between its proximal and distal ends.

In claim 2, it is mentioned that each guide sleeve and its respective auxiliary sleeve have a diverging development starting from the proximal ends. Claim 3 states that each guide sleeve and auxiliary sleeve have their own main axis and auxiliary axis, respectively. The auxiliary axis intersects the main axis in claim 4, and in claim 5, it is mentioned that the auxiliary axis forms an angle with the main axis. This angle is specified to be between 20° and 60° in claim 6.

The auxiliary axis reaches a minimum distance from the main axis in proximity to the virtual surface of the vertebra, as stated in claim 7. In claim 8, it is mentioned that the auxiliary axis reaches a minimum distance from the main axis or intersects the main axis within 5 mm from the virtual surface, but inside the vertebra. Claim 9 states that the auxiliary axis forms an angle with the portion of the virtual surface it is incident upon, which is favorable for the use of a preparatory drill. This angle is specified to be between 60° and 120° in claim 10.

Other claims include the orientation of the guide sleeves, where their proximal ends are further apart than their distal ends (claim 11), the shape of at least one support element as a hook to partially encircle a portion of the vertebra (claim 12), the inclusion of a handle (claim 13), and specific angle ranges for the angle mentioned in claim 6 (claim 14: 25° to 45°) and claim 10 (claim 15: 75° to 105°).

Overall, this patent describes a disposable guide device for spinal surgery that includes guide sleeves, support elements, and auxiliary sleeves. The device is designed to provide precise guidance during surgical interventions on a patient's vertebra, with specific configurations and angles to ensure optimal performance.
