Definitions
- the invention relates to a needle guide means for intracorporeal sclerotherapy of a puncture needle to be inserted percutaneously into a patient, with an upper plate element that can be arranged at a distance from the patient and a lower plate element that can be arranged facing the patient, which are rigidly spaced apart from one another and each have a large number of through-holes for passing through the puncture needle provide.
- Biopsy needles in particular are used as puncture needles for taking tissue samples.
- injection needles for the controlled administration of a substance in a specific region inside the body as well as guide needles for surgical screws or drills can also be used.
- puncture needles are used in medical therapies for targeted stimulation. In all of these applications it is important to position a defined part of the puncture needle - primarily its tip - at a desired location inside the body.
- a controlled introduction of the puncture needle is required, ie the puncture site on the body surface and the puncture channel are selected on the basis of various criteria.
- CT X-ray tomography
- fluoroscopy fluoroscopy
- 3D X-rays 3D X-rays
- MRT magnetic resonance imaging
- a preferred needle guide means for precise positioning and intracorporeal introduction of a puncture needle is described in publication WO 2017/202590 A1.
- the known needle guide means can be placed on the skin surface of a patient for the purpose of needle positioning and has an upper plate element arranged away from the patient and a lower plate element arranged facing the patient. Both plate elements are rigidly spaced from each other and each provide a large number of through-holes for a puncture needle to pass through.
- the individual through holes in the plate elements have star or cushion-shaped through hole contours, each with four support point areas located in the corners, the geometry of which is selected so that a puncture needle is always guided by two opposite flanks and is centered within the respective support point area.
- the needle guide means explained above is decisive for the exact positioning and introduction of a puncture needle into the patient contributes, after intracorporeal positioning, the needle guide means represents a mechanical obstacle for certain further diagnostic or therapeutic measures on the patient, which can be removed from the patient by extremely careful lifting along the spatial extension of the extracorporeal puncture needle section.
- this measure requires a lifting process which is extremely difficult to carry out and which has to be carried out manually by the respective doctor. Even the slightest force acting transversely to the puncture needle caused by improper lifting of the needle guide means in the longitudinal extent of the extracorporeal puncture needle area can ultimately cause maladjustment of the intracorporeal puncture needle area.
- the invention is based on the object of providing a needle guide for the intracorporeal sclerotherapy of a puncture needle to be inserted percutaneously into a patient, with an upper plate element that can be arranged at a distance from the patient and a lower plate element that can be arranged facing the patient, which are rigidly spaced apart from one another and each have a large number of through-holes for passage provide the puncture needle, so that a removal or removal of the needle guide means from an intracorporeally placed and sclerosed puncture needle should be gentle on the patient and without the risk of maladjustment of the intracorporally sclerosed puncture needle area.
- a needle guide means for the intracorporeal sclerotherapy of a puncture needle to be inserted percutaneously into a patient is characterized by the features of the preamble of claim 1 in that the upper and lower plate elements can each be separated into at least two plate element parts and that the at least two plate element parts are all in an assembled state Limit through holes per panel element together.
- the at least two panel member parts of the top panel member are connected to a top frame enclosing the top panel member.
- the at least two plate element parts of the lower plate element are connected to a lower frame comprising the lower plate element.
- Both frames i.e. the upper and lower frame, are also rigidly connected to one another via a connection structure which can optionally be separated in such a way, for example by means of a detachably fixed plug connection, so that the upper frame can be separated from the lower frame.
- the at least two plate element parts are preferably designed in the manner of an interdigital finger structure, i.e. each plate element has comb-like finger elements, each of which is oriented parallel to one another
- a plurality of through-hole contours formed in half are arranged along the finger elements in such a way that when the at least two plate element parts are assembled, the through-hole contours in halves of two directly adjacent finger elements completely delimit the through-holes in pairs.
- the at least two plate element parts of the upper plate element can be releasably firmly connected to the upper frame and the at least two plate element parts of the lower plate element can be releasably firmly connected to the lower frame.
- the two frames which are rigidly connected to one another via the connecting structure, can then be lifted off the intracorporeally located puncture needle in a contact-free manner.
- a further preferred embodiment provides that the upper and lower frame can be separated into at least two frame parts.
- the at least two plate element parts per plate element can be firmly connected to the respective frame parts.
- the frame parts that separate in the process can be removed laterally in opposite directions from the puncture needle.
- the proximal end of the puncture needle is connected to a catheter that leads further, the fact that the upper and lower frames can be separated also makes it possible to avoid laborious unthreading of the remaining frame construction along the proximally leading catheter.
- Fig. 1 needle guide means as a structural unit
- Fig. 2 Representation of the needle guide means with separate
- FIG. 1 shows a needle guide designed according to the solution as a structural unit for use in positioning and inserting a puncture needle into a patient. Neither the patient nor the puncture needle are illustrated in FIG.
- the needle guide means has an upper frame 1 and a lower frame 2, each of which is of square design.
- the upper frame 1 as well as the lower frame 2 span an upper and lower frame plane E1, E2, which are arranged spatially parallel and orthogonally spaced apart from one another.
- the upper and lower frames 1, 2 each have at the four corners of the frame rigid connecting struts 3, via which both frames 1, 2 assume a spatially fixed assignment. All four frame struts 3 together form a connection structure that rigidly connects the upper and lower frames 1 , 2 .
- the upper frame 1 surrounds an upper plate element 4 which is connected to the upper frame 1 via two joining areas 5,6. Otherwise the upper plate element 4 is loosely enclosed by the frame 1 .
- the upper plate element 4 has a multiplicity of individual through holes 7 which are arranged in a grid pattern. Each of the through-holes 7 is of identical design and has a through-hole contour which is star-shaped with four corner regions each. Each corner area of a through hole 7 forms a stable and spatially defined support point area for the puncture needle.
- the upper plate element 4 extends parallel within the upper plate plane E1.
- the lower plate element 8 is connected to the lower frame 2 via two connecting areas 9,10.
- the lower plate element 8 has a multiplicity of through-holes 7 arranged in a grid-like manner.
- both the upper plate element 4 can be separated into at least two plate element parts 41 , 42 and the lower plate element 8 into at least two plate element parts 81 , 82 .
- the upper plate element and also the lower plate element 8 are each composed of two plate element parts 41, 42 or 81, 82, which are designed in the manner of an interdigital finger structure.
- Each plate element part 41, 42, 81, 82 has comb-like finger elements F with finger longitudinal extensions oriented parallel to one another, with a plurality of through-hole contours 71 formed in half being arranged along the finger elements F. In the assembled state of the through-hole contours 71 formed in half along the finger elements F, two through-hole contours formed in half completely enclose a through-hole 7 .
- Each plate element part 41, 42 or 81, 82 can be connected to the upper frame 1 or lower frame 2 via a detachably fixed connection structure 411, 421, 811, 821.
- the upper frame 1 can be separated into two upper frame parts 11, 12 by means of two snap-in connections SRV, but not necessarily in an advantageous manner.
- the lower frame 2 can also be separated into two lower frame parts 21, 22 via two snap-in connections SRV in the same, but not necessarily advantageous form.
- each of the connecting struts 3 is designed to be separable, ie each of the connecting struts 3 is composed of two strut segments 31, 32 which can be assembled via a detachable plug-in mechanism.
- Top plate member 1 Top plate member 1, 42 Top plate member parts 11, 421 Connection structures
