Abstract
A localizing unit for an X-ray diagnostic system covered with a sterile drape is provided. In one embodiment, the localizing unit can be sterilized and has an adapter, which includes a mechanism for puncturing the sterile drape and a mechanism for temporarily securing the sterile drape on a housing of the X-ray diagnostic system. The adapter may be detachably held in predetermined holders on the housing of the X-ray diagnostic system and may be positioned on the housing in a reproducible manner. In some embodiments, the mechanism for temporarily securing the sterile drape on the housing includes an elastically deformable, surrounding seal, which upon positioning the adapter, produces a force on the sterile drape in a direction perpendicular to the surface of the housing.
Core Innovation
The invention relates to a sterilizable localizing unit adapted for detachable and reproducible positioning on a housing of a nonsterile surgical X-ray diagnosis system that is covered at least in part with a sterile drape. The localizing unit includes an adapter with at least one mark detectable by a position detection system, means for puncturing the sterile drape, and means for temporarily securing the sterile drape on the housing while the adapter is positioned on the housing.
The temporarily securing of the sterile drape is achieved by an elastically deformable, surrounding seal that produces a force on the sterile drape in a direction perpendicular to the surface of the housing during positioning of the adapter. The adapter is positioned and fixed using detachable and reproducible positioning means that comprise a pushbutton, with a spring, a cone, and one or more ball bearings, where the spring provides a resistance force against the pushbutton.
In further embodiments, the adapter includes detectable marks for a position detection system, including holding plate marks arranged relative to a coordinate system, scannable pointer-detectable marks, or auto-reflection targets detectable by the position detection system. The configuration uses a releasable locking mechanism and supports an adapter structure interacting with the sterile drape and the housing of an X-ray diagnostic setup.
Claims Coverage
The document includes two independent claims. Across them, the main inventive features cover a sterilizable localizing unit or adapter that punctures and temporarily secures a sterile drape, detachable and reproducible positioning on the housing using a pushbutton locking/unlocking mechanism with spring, cone, and ball bearings, and detectable adapter markers for a position detection system.
Sterilizable localizing unit for detachable and reproducible positioning on draped X-ray diagnosis housing
A sterilizable localizing unit adapted for detachable and reproducible positioning on a housing of a nonsterile surgical X-ray diagnosis system covered at least in part with a sterile drape, comprising an adapter having at least one mark detectable by a position detection system, means for puncturing the sterile drape, means for detachable and reproducible positioning of the adapter on the housing, and means for temporarily securing the sterile drape on the housing while the adapter is positioned on the housing.
Elastically deformable surrounding seal producing perpendicular drape force during positioning
The means for temporarily securing the sterile drape on the housing comprises an elastically deformable, surrounding seal, which produces a force on the sterile drape in a direction perpendicular to the surface of the housing during positioning of the adapter.
Pushbutton locking and unlocking with spring, cone, and ball bearings
The means for detachable and reproducible positioning of the adapter comprises a pushbutton with which the adapter can be locked or unlocked with respect to the housing, the pushbutton comprising a spring, a cone, and one or more ball bearings, the spring providing a resistance force against the pushbutton.
Removably attachable adapter with drape puncturing and releasable locking to a predetermined position
An adapter for removably attaching a sterile drape to a medical diagnostic system, comprising a lower portion configured for removable attachment to a borehole in a housing of the medical diagnostic system, the lower portion comprising a tip configured to puncture the sterile drape, and the lower portion comprising a locking mechanism configured to releasably lock the adapter into a predetermined position on the medical diagnostic system.
Position-detection markers and drape-securing seal
An upper portion having one or more markers capable of being detected by a position detection system, and a seal configured to secure a portion of the sterile drape between a portion of the adapter and the housing of the medical diagnostic system.
Pushbutton locking mechanism with conical member and spring-actuated radially movable ball bearings
The locking mechanism comprises a pushbutton actuatable between a locked position and an unlocked position, the pushbutton comprising a user-actuatable button, a conical member capable of moving along a longitudinal axis, a spring configured to provide a spring force along the longitudinal axis, and one or more ball bearings capable of moving radially toward and away from the longitudinal axis in response to movement of the conical member.
Overall, the independent claims require an adapter or localizing unit that punctures and temporarily secures a sterile drape on a housing of an X-ray diagnosis system while providing detectable markers for a position detection system. The adapter or localizing unit is detachable and reproducibly positioned using a pushbutton locking and unlocking mechanism defined by a spring, cone, and one or more ball bearings, and the drape is secured with a surrounding elastically deformable seal applying a force perpendicular to the housing surface during positioning.
