Description

[0001] This application relates to a connector system for handheld medical imaging devices.

[0002] Handheld medical devices can be used for both diagnostic and therapeutic purposes. A well-known example of a handheld medical imaging device is an ultrasound device (ultrasound, ultrasound probe).

[0003] For various applications, precise tracking of handheld medical imaging devices is required, such as for providing 3D ultrasound images.

[0004] For example, tracking may include determining the absolute position of a handheld medical imaging device in space. In one example, tracking may include determining changes in position of the handheld medical imaging device (determining relative position). Changes in position may include movement of the handheld medical imaging device from a first position to a second position and / or rotation and / or tilting of the handheld medical imaging device. Tilt may be roll. Tilt may be yaw. Tilt may be pitch.

[0005] Tracking can be performed using a tracking target mounted on a handheld medical imaging device. The tracking target can be an actively tracked target or a passively tracked target. Tracking can be performed using sensors or tracking devices deployed on the handheld medical imaging device.

[0006] A simple and safe deployment of such tracking targets, sensors, and / or tracking devices is required to improve tracking performance. Therefore, a reliable connection mechanism is needed for linking handheld medical imaging devices with additional tracking devices, sensors, tracking targets, and / or optical targets.

[0024] When the inserter portion is inserted into the receiving portion in a predetermined orientation, the edge segment may face the boundary segment. When the inserter portion is inserted into the receiving portion in a predetermined orientation, the edge segment and the boundary segment may be adjacent. The edge segment may be complementary to the boundary segment. The edge segment and the boundary segment may be complementary to provide mutual surface contact over a large portion of their respective surfaces.

[0026] According to one embodiment, the first boundary segment is configured to be complementary to the first edge segment, such that when the inserter portion is arranged in the receiving portion in a predetermined orientation, the first boundary segment and the first edge segment are abutted. The obtuse angle associated with the first boundary segment may be equal to another obtuse angle associated with the first edge segment. Lateral movement of the inserter portion within the receiving portion can be advantageously reduced. One advantage is that the position of the inserter portion within the receiving portion can be stabilized against lateral displacement. Another advantage is that the position of the inserter portion within the receiving portion can be stabilized against rotational displacement.

In one embodiment, the polarity of the magnetic elements of the inserter portion is opposite to the polarity of the magnetic elements of the receiver portion.

[0034] When the inserter portion is received by the receiving portion in a predetermined orientation, the shape fit of the edge segments and boundary segments can provide torsional resistance of the inserter portion relative to the receiving portion.

When the inserter portion is received by the receiving portion in a predetermined orientation, the form fit and / or magnetic connection prevents rotation of the inserter portion relative to the receiving portion. When the inserter portion is received by the receiving portion in a predetermined orientation, the form fit and / or magnetic connection prevents displacement (lateral movement) of the inserter portion relative to the receiving portion.

When the inserter portion is received by the receiving portion in a predetermined orientation, the form fit and / or magnetic connection provide precise spatial alignment of the inserter portion relative to the receiving portion.

[0036] One advantage is that the same relative alignment (of the inserter portion relative to the receiving portion) can be easily and reliably achieved and locked. Another advantage is that no new calibration may be required after replacing the additional unit. The replacement process can be advantageously simplified and accelerated.
