Problems solved by technology

Coupling multiple interstitial needles to the guide unit itself requires outstanding skill and a lot of time before the actual radiation therapy is performed, during which time the patient is already on the treatment table, causing discomfort to the patient
When attempting to guide the interstitial needle into the hole or opening in the guide unit, undesired damage or damage may be caused to the wall of the patient's body cavity, and there may even be a risk of puncturing it
Moreover, the way in which the interstitial needle is coupled to the known device has the disadvantage that there is a possibility of the interstitial needle becoming unintentionally (and undesirably) detached from the guide unit
This may lead to displacement of the catheter channel relative to the tumor tissue to be treated, thus adversely affecting the treatment parameters of said patient

Embodiment Construction

[0046] figure 1 Embodiments of assemblies according to the invention are disclosed. Reference numeral 11 represents a treatment table, on which the female patient will be placed in the lithotomy position. The treatment table 11 has a support 12 on which an installation tool 10 is fixed. The function of the mounting device 10 is not relevant to the invention, it is used to position the medical tool relative to the patient's body according to the medical treatment to be performed.

[0047] exist figure 1 In this case, the mounting device 10 (or the clamping device 10 ) holds in a clamping manner a part of an embodiment of an assembly according to the invention.

[0048] The assembly according to the invention comprises an endoluminal part 20 and at least one guide unit 25 to which the endoluminal part 20 can be connected. The endoluminal part 20 consists of at least one (here two) support tubes 21 and 22 . The first support tube 21 extends in an intrauterine tube 23 which c...

Abstract

The invention relates to an assembly for performing brachytherapy treatment of tumour tissue in a human or animal body comprising an intracavitary component and at least one guiding unit, said at least one guiding unit exhibiting a longitudinal axis and being connectable to said intracavitary component, and wherein said at least one guiding unit is provided with coupling means for coupling at least one interstitial needle-assembly for delivering treatment to said tumour tissue. The assembly has coupling / uncoupling means arranged to allow a displacement of said at least one interstitial needle-assembly in a direction transverse to said longitudinal axis and to prevent a displacement of said at least one interstitial needle-assembly in a direction parallel to or a pre-defined angle to said longitudinal axis. This coupling principle allows for the preparation of the guiding unit before the patient is being hospitalized and positioned in the treatment room and will prevent the unwanted uncoupling of the interstitial needle-assembly during the actual treatment being performed, further reducing the risk of adversely affected treatment parameters (location and duration of the radiation being administered to the patient).

Description

technical field [0001] The invention relates to an assembly for performing brachytherapy for the treatment of tumor tissue in a human or animal, comprising a lumen part and at least one guiding unit, said at least one guiding unit being connectable to said lumen part, and wherein said The at least one guide unit is arranged for receiving at least one interstitial needle assembly for delivering therapy to the tumor tissue. [0002] The invention also relates to an interstitial needle assembly for performing brachytherapy in the treatment of tumor tissue in a human or animal, and by means of the interstitial needle assembly utilizing at least one source of energy radiation disposed near or in said tumor tissue through a catheter passageway, Brachytherapy is a method of treating tumor tissue in humans or animals. Background technique [0003] The radiotherapy apparatus described above comprising interstitial needles is known in the medical field and is suitable for the treatme...
