Problems solved by technology
Another possible disadvantage is the masking nature of the switch, i.e. it may be difficult to detect that the coupling element has been successfully connected to the correct delivery tube until the connector locking mechanism in the switch is activated and the delivery unit is sent out. Detects that the delivery tube connector is installed by the equipment operator in the correct switch opening and is sufficiently deep in the switch

Embodiment Construction
[0020] The present invention provides a device for delivering and positioning at least one therapeutically emitting element, such as a capsule 1 in which a radioactive source is present. The capsule may contain a radiation source as is known in brachytherapy and by attaching the capsule to a delivery element, eg a wire, the radiation source may be delivered by coiling a delivery wire in or out.
[0021] exist figure 1 An embodiment of the invention is shown with a capsule 1 that can be delivered from a shielded safe 2 into at least one treatment channel (e.g., a needle, catheter, tube, or source guide channel of an applicator) for temporary placement in in or on the patient's body. The device is provided with at least one therapeutic emitting element (eg a radiation capsule 1 ) and a plurality of delivery wires 4 . The capsule 1 can be connected to one end of one of the delivery wires 4, and when one of the drive motors 10 drives the associated delivery wire 4, the plurality...

The present invention relates to a medical device for delivering and positioning a therapy emitting element into a treatment channel for temporary placement in or on a patient's body to treat a tumor. The therapy emitting element is connected to the delivery element and is driven by at least one drive motor. The device has a connecting element including a plurality of connector openings. The connecting elements are used for connecting the delivery pipes to the corresponding connector openings. The delivery tube is connected to an applicator, needle, tube or catheter for driving the delivery element into the treatment channel. The device has a selector mechanism by means of which a plurality of conveying elements are driven. An annular guiding device guides the conveying element into a connector opening in the connecting element. The annular guide device also includes a plurality of spaced apart outlets. The inlets of the plurality of patterns are respectively connected to the outlets through guide channels. Each outlet is aligned with a connector opening in the connection element to allow a transport element from each outlet to be driven into the connector opening.
Description
technical field [0001] The present invention belongs to the field of medical treatment. In particular, the invention is in the field of treating tumors. Background technique [0002] Brachytherapy is a form of radiation therapy that uses at least one radioactive capsule (sealed source) or X-ray source that is temporarily inserted into or onto the patient's body near or within a tumor. In this way, radiation damage to healthy tissue can be reduced compared to external radiation therapy and may lead to more effective treatment. [0003] In US20050261539 a brachytherapy device, commonly referred to as a brachytherapy afterloader, is described which has a radiation source temporarily placed in the patient's body. The radioactive source is transported out of the shielded safe via (at least part of) a flexible transport element (eg wire, string, composite structure, tube). The delivery element is driven by a motor via a switch (selector mechanism) along the delivery tube to the...
