Patent number: 12343278Abstract: A head stabilization device useable for stabilizing a head of a patient during a medical procedure includes a modular design where stabilization assemblies of various configurations are interchangeable at receiving portions along a frame. The device includes a tensioning feature positioned away from the stabilization assembly but still operable to increase or decrease an amount of force the stabilization assembly applies to the patient's head. The device includes a locking feature for a stabilization assembly having a rotatable member having one or more stabilization features connected thereto. The device includes an adjustment feature to adjust a spacing between frame members with the adjustment feature providing a continuous range of adjustment rather than finite adjustment increments.Type: GrantFiled: January 29, 2021Date of Patent: July 1, 2025Assignee: pro med instruments GmbHInventors: Peter Forst, Matthias Esser, Andreas Blum, David Devran Culha, Matthias Edgar Schuele

Patent number: 12285369Abstract: A head stabilization device includes a stabilization assembly and an applicator to control an amount of force that a stabilization feature applies to the head of the patient. The applicator includes a torque control feature that ensures a desired torque setting is not exceeding during use. The applicator can be detached from the remainder of the system such that the head stabilization device is usable without having a connected torque controlling feature or structures. The applicator in one version controls torque by adjusting a bending length of a pair of arms that extend within the applicator.Type: GrantFiled: November 19, 2020Date of Patent: April 29, 2025Assignee: pro med instruments, GmbHInventors: Peter Forst, David Devran Culha, Marco Stephan Willesch, Matthias Edgar Schuele, Matthias Esser, Jan Heiko Mertens

Patent number: 12090000Abstract: A head stabilization device having the form of a skull clamp includes a first pin assembly and a second pin assembly. The pin assemblies are positioned opposite each other, and the first pin assembly has a first pin while the second pin assembly has a pair of pins. The pins used with the skull clamp are non-uniform. In this respect skull clamp can apply an equal force to a head of a patient from both sides. Additionally, the pressure at each pin location can be the same or substantially the same. This allows each of the pins to have the same or similar bone penetration when in use stabilizing the head of the patient.Type: GrantFiled: September 25, 2019Date of Patent: September 17, 2024Assignee: pro med instruments GmbHInventors: Jan H.

Patent number: 8844536Abstract: A locking apparatus for use with a head fixation device allows for a stabilizing fixture, such as a rocker arm having a pair of skull pins, to be selectively secured so that the stabilizing fixture can be adjustably rotated to a desired position. In some version the locking apparatus includes a connector that is retained within an opening in a portion of the head fixation device. The connector can translate within the opening and is restricted from rotation. The translating of the connector permits the connector to engage an arch member that retains the stabilizing fixture. The engagement of the connector and arch member is accomplished, in some versions, by way of matching axial oriented toothed portions or starburst features. In some versions the teeth on the starburst features include a chamfer surface.Type: GrantFiled: August 24, 2011Date of Patent: September 30, 2014Assignee: pro med instruments GmbHInventor: Matthias E.
