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.
- Advantageous embodiments and further developments are described in the dependent claims.
- a medical device for performing a biopsy on a region of a body to be examined has at least three connecting elements, by means of which the device can be attached to the region of the body or which can be attached to anchoring elements which are arranged on the region of the body ,

- At least the connecting element is in this case made of a lightweight material.
- the medical device is very light, which increases the wearing comfort. In addition, you can work with respect to conventional systems smaller dimensions.
- the at least three connection elements and the sleeve are formed from the lightweight material.
- the sleeve is designed such that an entry point or target point of the medical instrument coincides in the region of the body with the center of mass of the medical device. This results in a particularly stable arrangement, the one
- the at least three connecting elements may be designed for fastening to bone anchors which serve as anchoring elements.
- Bone anchors can be used to select a fixed point of attachment to a bone, thus simplifying positioning of the medical device.
- the medical device may comprise, as the medical instrument, a drill for creating a suitable penetration opening, a biopsy needle for performing the biopsy, at least one electrode for deep brain stimulation, at least one endoscope together with a light guide cable for photodynamic therapy and / or an ultrasound head is typically adapted to emit pulsed ultrasonic waves.
- the connecting element may be web-shaped, that is to say in particular have a length which is at least around
- both the length and the width and the thickness of the connecting element are not changeable, but predetermined or fixed.
- the lightweight material is typically selected from plastic, preferably a polycarbonate (PC), a polyamide (PA) and / or acrylonitrile-butadiene-styrene (ABS), aluminum, titanium, an alloy of said elements or a fiber composite, preferably one or more comprising said materials. 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. Finally, the previously defined device is provided by a rapid prototyping method, a computer-aided design (CAD) and / or a computer-aided manufacturing
- the described medical device can be produced quickly and cost-effectively, and because of the adaptation to the respective patient, no sterilization after the operation is necessary.
- the medical device is disposable so there are no usage restrictions for particular diseases such as Creutzfeldt-Jacob disease or slow virus infections / prions.
- 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.
- Fusing may be based on anatomical and / or predefinable, typical artificial or artificial reference points.
- the reference points such as the bone anchors, are or will be located at the area of the body to be examined more closely.
- Rounding be provided in generating the medical device based on the recording in order to facilitate the handling of the medical device.
- at least one threaded bore is provided for fastening further holders or devices.
- polyamide casting for the rapid prototyping process, depending on the material used, polyamide casting, binder jetting, stereolithography, fused deposition modeling, multi-jet modeling, selective laser melting or selective laser sintering should be used.
- a computer program product may include a computer program having software means for performing the described method when the computer program is executed in an automation system.
- Figure 1 is a perspective view of a head with the medical device for a biopsy.
- Fig. 2 is a side view of a marker;
- FIG. 3 is a perspective view of a bone screw and connected to the bone screw marker in a figure 2 corresponding view.
- FIG. 1 shows a perspective view of a head 2 as a region of a body 8 to be examined.
- another body part for a biopsy by means of the device described in more detail may be provided.
- Three bone anchors have already been attached to the head 2 or skull as part of the biopsy procedure to be performed or before the biopsy procedure to be performed in order to fix a target device to be produced.
- the three bone anchors were placed in the tabula externa of the bony skull (occiput, temple or zygomatic bone on both sides) and serve as both artificial landmarks and as contact points.
- a number of bone anchors to use also called
- Fixing anchors are referred to, resulting from a compromise between mounting stability and weight of the medical device.
- the number should be at least three, however, to ensure sufficient stability. Typically, exactly three bone anchors are placed. Too few attachment points will result in an unstable connection, while too many attachment points increase weight and increase the complexity of the medical device, which adversely affects their accuracy. It can also be provided to attach anchoring elements or connecting elements 1 non-invasively only to the area.
- the bone anchors were screwed into the skull at the positions shown in FIG. The placement depends on the location of the tumor in the brain. However, attempts are being made to establish standardized points for the typical tumor localities.
- Computed Tomography CT
- MRI magnetic resonance imaging
- the data contained in the CT image and the MRI image can be fused together by anatomical and / or artificial landmarks.
- determination of target and entry coordinates takes place, which is the entry point 5 of the medical instrument 6, for example a medical instrument
- Drill or a biopsy needle In the illustrated embodiment, the entry point 5 coincides with the center of mass of the finished medical device. Finally, the biopsy is localized, sparing eloquent regions and risk structures.
- a construction of the medical device is made to the given parameters such as coordinates of the connection elements 1 or anchoring elements and the entry point 5. This can be done automatically.
- a biopsy needle from the connection elements 1 or anchoring elements and the entry point 5.
- connection elements 1 are added.
- the target device in the embodiment shown, a sleeve 3 for a drill or the biopsy needle is arranged centrally in the embodiment shown between the connection elements 1 and connected by means of a web-shaped connecting element 4 with the connection elements 1.
- the sleeve 3 is designed as a needle guide with a defined length and the exactly three connection elements 1 are structurally connected to the sleeve 3 as a needle guide element by the connecting elements 4.
- rounding 7 and threaded holes are added, for example, to adapt the shape of the connecting elements 4 in shape to the head shape and thus to obtain a compact medical device as possible.
- the connecting elements 1, the connecting elements 4 and the sleeve 3 are made in one piece in the illustrated embodiment and each rigidly connected together. In particular, none of said elements can perform a tilting or rotational movement without a corresponding co-movement of another of the elements. The said elements are therefore rigidly connected. In each case one of the connecting elements 4 connects in the illustrated embodiment, the sleeve with a single one of the connecting elements. 1
- the virtual device constructed virtually by means of a computer program can be transmitted as a data set to a computing unit, for example a computer, wherein the computer program has software means for carrying out the method described, if the computer program in the computer is performed as an automation system.
- the computer then controls an apparatus for performing the rapid prototyping method, the CAD method and / or the CAM method.

- a plastic holding tion as a medical device is obtained, which is very light with a weight between 200 g and 250 g, typically 300 g and much lighter than a comparable stereotactic frame, which usually weighs 3 kg.
- this device can be prepared by steam sterilization for use.
- the device can also be used for introducing at least one, preferably at least two electrodes for deep brain stimulation, for photodynamic therapy in which an endoscope together with an optical waveguide is introduced and / or for carrying out a treatment by means of pulsed ultrasound.
- only a single MRI scan is made using markers attached to the bone anchors, ie the later junctures of the medical device to be manufactured.
- These markers are attached to the existing bone screws, which are typically formed of a material suitable for magnetic resonance imaging, for example by screwing.
- the markers have for this purpose a cylindrical body which is filled with the medium. On one of the two a lateral surface of the cylindrical body defining surface is threaded.
- FIG. 2 shows a side view of a corresponding marker 9.
- FIG. 3 shows a perspective view of a bone screw 10, which is also referred to as a bone anchor, and also has a cutting thread on an underside, with which it can be fastened to the patient.
- the cutting thread is a receptacle with an internal thread, which is designed such that the thread of the marker 9 can be fastened therein.
- FIG. 4 shows, in a view corresponding to FIG. 2, how the marker 9 is connected to the bone screw 10.
