Definitions

  • the present invention relates to a medical device for performing a biopsy and a method for manufacturing the medical device.
  • Brain biopsies are designed to remove etiologically unclear damaged tissue (lesion) when other diagnostic procedures are depleted, symptoms increase, or the lesion is progressive in its growth. Tissue taken is examined histopathologically and after completion of the biopsy it is used for further therapy and prognosis estimation.
  • Stereotactic biopsies have been used in virtually unchanged form since the middle of the last century. Possible complications that can occur during or after a brain biopsy include, among others Hemorrhages near the sampling site, wound healing disorders and wound infections. It can also cause swelling or edema, which can lead to low to severe neurological impairment in the vicinity of brain eloquent centers (eg, speech center, motor center). It is therefore important to use a biopsy system with high accuracy while minimizing trauma to the intact surrounding tissue. This applies equally to biopsies on other parts of the body.
  • US Pat. No. 5,387,220 describes a stereotactic frame which uses natural reference points during an operation and need not be attached to the head by means of pins.
  • Biopsy needle can be adjusted so on the frame.
  • a biopsy can be accompanied by real-time magnetic resonance imaging (MRI) scans.
  • MRI magnetic resonance imaging
  • the course of the biopsy needle is monitored on the monitor and intervened under constant image control.
  • the method has a high accuracy, but is also expensive to carry out.
  • Veterinary biopsies usually work freehand, ie without a stereotactic system. However, you can also use brackets here.
  • a disadvantage of the described frame-based methods is that the size of the frame influences the handling during the operation.
  • the frame can lead to pain in the patient.
  • the fixation may lead to postoperative infections and surgery times with biopsy surgery procedures are generally about twice as high as with frameless tissue removal.
  • the present invention is therefore based on the object to develop a cost-effective, simple and error-prone system for biopsy. This object is achieved by a medical device according to claim 1 and a method for producing the medical device according to claim 9.

These materials are easy to process while providing the ability to create a mechanically stable device for performing the biopsy.
  • the connecting element may be rigid, in order to increase mechanical stability.
  • the connecting element should be unchangeable in its dimensions.
  • the connecting element can also be formed in one piece, ie consist of a single part, which likewise increases mechanical stability.
  • the connecting element, the sleeve and / or at least one of the anchoring elements, typically all anchoring elements are integrally formed and preferably bonded together materially.
  • a method for producing the described medical device comprises a step in which a recording of the region of the body is made by means of magnetic resonance tomography, by means of computed tomography and / or by means of ultrasound recordings. Subsequently, the medical device is generated by determining coordinates of anchoring elements disposed on the area of the body or coordinates of attachment points in the area of the body for terminal elements in the receptacle and constructing the corresponding terminal elements as well as a target point as an impact point the medical instrument is defined and fixed a position of the sleeve and at least one connecting element is provided.

  • a recording is made by means of magnetic resonance tomography and by means of computer tomography of the region of the body, wherein the two images are subsequently fused together.
  • the merged recording then serves to generate the device.
  • Magnetic resonance imaging for example, can be used to determine target points in the brain; in addition, this method enables very good soft tissue recognition and very good demarcation from intact tissue. Computed tomography in turn allows bony landmarks as well as bone anchors to be detected.
