Description

Connector system The present application relates to a connector system for a handheld medical imaging device. The handheld medical device may be used for diagnostic purposes and for therapeutic purposes. A well-known example of a handheld medical imaging device is an ultrasound device (ultrasound, ultrasound probe). For various applications, accurate tracking of a handheld medical imaging device is required, for example for providing 3D ultrasound images. For example, tracking may include determining an absolute position of the handheld medical imaging device in space. In one example, tracking may include determining a change in position of the handheld medical imaging device (determining a relative position). The change in position may comprise a movement of the handheld medical imaging device from the first position to the second position and/or a rotation of the handheld medical imaging device and/or a tilting of the handheld imaging device. Tilting may be rolling. The tilt may be yaw. The tilt may be pitch. Tracking may be performed by means of a tracking target mounted at the handheld medical imaging device. The tracking target may be an active tracking target. The tracking target may be a passive tracking target. Tracking may be performed by means of a sensor or tracking device arranged at the handheld medical imaging device. There is a need for a simple and safe arrangement of such tracking targets, sensors and/or tracking devices to enhance tracking performance. Thus, there is a need for a reliable connection arrangement for connection between a handheld medical imaging device and an additional tracking device, sensor, tracking object and/or optical object. This problem is solved by a connector system according to claim 1, a first connector part according to claim 13, a second connector part according to claim 14 and a method according to claim 12.

The interposer includes a bottom section and an edge section connected to the bottom section. The edge section is form-fitted with the boundary section such that the inserter portion can be received by the receiver portion in a unique predetermined orientation relative to each other. The receiving portion and the inserter portion each include a magnetic element configured to provide a magnetic connection therebetween to secure the inserter portion in the receiving portion in a predetermined orientation. The receiving portion may be configured to reversibly and repeatedly receive the inserter portion in a unique predetermined orientation. The inserter portion may be configured for reversible, repeated insertion into the receptacle in a unique predetermined orientation. In particular, a small, compact connector system may be provided, which may comprise a repeatable releasable connection means. Advantageously, the connector system may be reusable. The receptacle may be reusable. The inserter portion may be reusable. The upper rim section may completely surround the base section. In one embodiment, the upper rim section surrounds a portion of the base section along the circumference of the base section. In one embodiment, the upper rim section surrounds the base section along more than 30% of the circumference of the base section. In one embodiment, the upper rim section surrounds the base section along more than 50% of the circumference of the base section. In one embodiment, the upper rim section surrounds the base section along more than 70% of the circumference of the base section. The receptacle may comprise a plurality of upper edge sections, in particular a plurality of separate upper edge sections. In one embodiment, the receptacle tapers from the upper rim section toward the base section. The recess may widen from the base section toward the upper edge section. The obtuse angle may be from 90 ° to 180 °, in particular from 90 ° to 170 °. The boundary section may have an inclination greater than a plane and less than a right angle relative to the base section. In one embodiment, the border segment includes a bend. The bend may bend from the upper edge section toward the base section. According to an embodiment, the border section is curved from the upper edge section towards the base section. The tangent to the curvature of the boundary section and the base section may enclose an obtuse angle. In particular, each tangent to the curvature of the bou
