Definitions
- Device for holding and / or guiding medical instruments including endoscopes, or cannulas, preferably introduced in the field of interventional radiology or minimally invasive surgery, introduced into the patient's body with a defined orientation by way of puncture and then optionally within the patient's body up to a defined penetration depth are driven.
- needle trocar Such a holding device, a so-called “needle trocar”, is previously known inter alia from DE 198 08 220 A1
- a stereotactic needle holding device previously known, with the help of such a needle should be placed as defined as possible, where appropriate, an imaging system, such as a magnetic resonance tomograph
- an imaging system such as a magnetic resonance tomograph
- the proposed solution therefore comprises a clamping device with an adjustable channel, wherein the clamping device can be glued to the skin of the patient as a whole.
- the needle holder itself includes a ball joint connected to a mounting plate which articulates an instrument insertion tube. By means of a clamping device associated with the ball joint, the instrument insertion tube can then be fixed in the fixed position.
- the neurotrokar device disclosed there differs from the needle trocar device already described in that the already mentioned attachment plate can not be attached to the patient's body but to the patient's head.
- the patent application describes a positioning grid having cavities for receiving contrast agents.
- the contrast media received in the cavities of the positioning grid ensure that the positioning grid or its cavities can be displayed in an imaging system, that is, for example, by means of an MRI scanner.
- the positioning grid which is thus clearly visible in the imaging system, can thus be used to select and prescribe a medically useful puncture site on the patient's body using the imaging system, by gluing the positioning grid onto the skin of the patient's body at the selected location. It is generally perceived as problematic in connection with the already mentioned positioning aids that any incorrect alignment or incorrect positioning is difficult to correct.
- the invention is therefore based on the object to provide a holding device for medical instruments or cannulas, which allows the intervention of the attending physician at any time - even after insertion of the instrument or the cannula in the patient's body and any further patient movements and at the same time optimal support of the attending physician.
- the solution of the object according to the invention is achieved in that the holding device according to the invention, in contrast to the known from the prior art holding devices at any time, but especially after Interticiani- on, from the instrument and / or the cannula is intended solvable.
- the holding device according to the invention is in the context of the invention, preferably detachably, connected to a mechanical guide system.
- This guidance system ideally works with an imaging system, such as an MRI (Magnetic Resonance Imagine) system or. an MRI (Magnetic Resonance Tomography) system or a CT (Computed Tomography) system together.
- an imaging system such as an MRI (Magnetic Resonance Imagine) system or. an MRI (Magnetic Resonance Tomography) system or a CT (Computed Tomography) system together.
- the above system is usually supplemented by display and control elements, such as a touch screen or a computer with graphical user interface, with the help of the imaging system and the mentioned display and controls the doctor can set the punctuation and intervention.
- display and control elements such as a touch screen or a computer with graphical user interface
- the system can then automatically calculate at which point and in which orientation of the patient 's body the instrument resp. the cannula must be attached. Furthermore, the connected guidance system can approach the punctuation point of the patient body automatically. After punctuation has been carried out, preferably by the attending physician in the predetermined orientation, further insertion of the medical instrument or cannula at the puncture point in the predetermined orientation takes place. if by the attending physician himself.
- the guide system according to the invention therefore deliberately and expressly dispenses with automating the puncture and advancement of the cannula or of the medical instrument into the patient's body.
- the holding device used in this context consists for the purpose of introducing a cannula from a sleeve holder, which essentially comprises an angle element consisting of a retaining shoulder, and a sleeve seat arranged at right angles thereto.
- the sleeve seat as such is provided with a passage for receiving a portion of the sleeve, wherein the sleeve is already provided here with a performed cannula.
- the implementation of the sleeve seat for receiving the corresponding sleeve portion or the sleeve as a whole is provided over its entire longitudinal extent with a longitudinal slot. About this longitudinal slot or the proximal opening of the sleeve holder can be solved at any time, the sleeve holder of the sleeve and thus also the cannula from the sleeve holder.
- the sleeve is moved in the proximal direction relative to the sleeve seat until the sleeve has come out of engagement with the bushing and in the other only the cannula is enclosed by the mentioned implementation of the sleeve seat.
- the cannula can be easily unwound at any time through the longitudinal slot of the implementation and thus an approximately connected guide system can be completely decoupled from the cannula. This is useful, for example after completion of automatic punctuation, when the cannula or the medical instrument is inserted so far until it is more or less automatically through the skin and the patient tissue is held in the desired orientation in the desired orientation.
- the sleeve holder has a retaining shoulder, wherein the retaining shoulder is provided on the side facing away from the sleeve seat with a holding block.
- the holding block is used for coupling a guide system described above.
- the sleeve holder so the sleeve can be releasably connected with the cannula received therein with a mechanically or electromotively moving guide system.
- the sleeve used in conjunction with the above-mentioned sleeve holder is usually provided at its proximal end with a radially expanded sleeve flange, the sleeve flange seated plan on the sleeve seat when mounted as intended, so that the sleeve in axia- ler direction is obtained in particular during the propulsion of the cannula through the sleeve.
- the sleeve seat of the sleeve holder also provides a stop for the sleeve received in the sleeve holder.
- the cannula can be unproblematically threaded through the longitudinal slot of the implementation.
- the sleeve seat can also be provided with a triangular recess, wherein the triangular tip of the recess facing the retaining shoulder preferably has a notch transverse to the sleeve seat.
- This triangular tip and / or its notch serves the immediate purpose of a cannula or a medical instrument, which may, if necessary, additionally be held with an angle counterpart pressed about by the attending physician. The puncture and the further feed can in turn be carried out manually.
- the sleeve seat can also be provided with an articulated arrangement such that the otherwise two-part formed sleeve seat can be opened and the sleeve can be connected to the sleeve seat.
- the articulated assembly is closed again, a closed passage is provided with the sleeve seat.
- the sleeve holder as such can also be designed in several parts such that the sleeve seat can be decoupled from the retaining shoulder as a whole.
- the decoupling of the sleeve seat from the retaining shoulder is again carried out simply by an axial movement of the sleeve seat relative to the retaining shoulder.
- the holding device can be designed as a controllable gripping element.
- the gripping element can be designed, for example, analogously to the mechanics of an iris diaphragm, as used in the field of SLR cameras.
- This gripping element can then in turn be provided with operating elements, such as a voice or foot control, and optionally an optical sensor system.
- operating elements such as a voice or foot control, and optionally an optical sensor system.
- the system automatically grips the sleeve presented to it and, in the manner described above, carries out the punctuation prescribed by the physician in the orientation initially predetermined by the physician with the aid of an imaging system and then the surgeon at this point the medical instrument or the cannula manually.
- the gripping element can be opened at any time via a corresponding control, and thus the medical instrument or the instrument can be opened. the sleeve with the cannula performed by the rest of the guide system are otherwise decoupled.
- FIG. 1 shows a holding device for a sleeve with a guided cannula in a perspective view
- Fig. 2 an alternative embodiment of the holding device with the sleeve held in a perspective view with a detail break
- Fig. 3 a holding device with a multi-part sleeve seat in a perspective view
- Fig. 4 a holding device with multi-part sleeve holder in perspective
- Fig. 5 a schematic diagram of the overall system.
- FIG. 1 shows a sleeve holder 1, which is designed primarily as an angle element.
- the angle element essentially consists of a retaining shoulder 2, from which a sleeve seat 3 extends forwards at an angle approximately at right angles.
- the sleeve seat 3 is more or less centrally completely penetrated by a bushing 4, the bushing 4 is opened over a continuous longitudinal slot 5 to the outside.
- a cone 6 is formed on the sleeve seat 3. This ensures that the cannula can also be inserted into the patient's skin at a comparatively acute angle.
- the sleeve holder 1 can be connected to a guide system (17) not shown in detail in FIG.
- the retaining shoulder 2 on the side facing away from the sleeve seat 3 a holding block 7 for connection to the guide system 17.
- the sleeve holder (1) shown in Figure 1 is usually made of a robust and easy to clean plastic, such as by a machining process or as an injection molded part.
- FIG. 1 A slightly different embodiment of the sleeve holder 1 is shown in FIG.
- a commercially available sleeve 10 is added in the implementation 4.
- the sleeve 10 initially has a through hole 11 for receiving a portion of a cannula 16, which is not shown in detail in FIG.
- With respect to the sleeve 10 itself can be distinguished between a sleeve cylinder 12, which is completely taken up in the passage 4 of the sleeve holder 1 as shown in Figure 2, and a relation to the sleeve Cylin 12 radially enlarged sleeve flange 13.
- the sleeve flange 13 is seated on the sleeve seat 3 when the sleeve 10 is mounted properly in the sleeve holder 1.
- the sleeve seat 3 thus provides a stop for the sleeve 10 which is particularly useful when a cannula 16 received in the sleeve 10 is advanced distally through the sleeve 10.
- the sleeve 10 is delivered with pre-assembled cannula 16 as a sterile disposable and disposable product.
- such a sleeve 10 preassembled with a cannula 16 can be inserted into a sleeve holder 1 according to FIGS. 1 and 2; the sleeve holder 1 is usually provided with a guide system 17, which will be explained below detachable, connected.
- the guide system is used in particular to guide the cannula 16 contained in the sleeve holder 1 to a desired point of punctuation of the patient and preferably to perform the punctuation itself there. Thereafter, the cannula 16 or a medical instrument is driven into the patient's body through the sleeve 10 up to the desired insertion depth likewise by the attending physician. After the intervention or in the event of complications occurring or whenever the physician desires, the sleeve 10 can be detached from the sleeve holder 1 in that the sleeve 10 inserted into the leadthrough 4 of the sleeve seat 3 moves upward in the image representation, ie toward the proximal side.
- the sleeve seat 3 may also be formed in several parts. As indicated by the triangular cutout 14 in the sleeve seat 3, can at the In the position of the triangular cutout 14, a second sleeve seat part can be connected to the sleeve seat part shown in FIG. 3 via an articulated arrangement not shown here, so that the cannula 16 itself closes and opens the articulated arrangement here without the sleeve 10 in FIG is absorbed by the sleeve seat parts enclosed implementation. The holder of the cannula 16 thus takes place by closing the articulated arrangement, while the decoupling of the cannula 16 is made possible by the holder 1 by opening the articulated arrangement.
- a counterpart can also be pressed manually by the doctor with the interposition of the cannula 16 in the triangular cutout 14.
- FIG. 4 A again different embodiment of the sleeve holder 1 is shown in FIG. As shown in Figure 4 is not the sleeve seat 3, but rather the sleeve holder 1 as such a total of two parts.
- the angle element of the sleeve holder 1 is formed only by the holding shoulder 2 being connected to the sleeve seat 3, with the connecting projections 15, 15 'reaching into each other as intended.
- Such a decoupling of the sleeve seat 3 from the retaining shoulder 2 can for example also be done by sneezing or careless movement of the patient.
- this is absolutely desirable because the patient by the positioning aid or the guide system 17 for Insertion of needles 16 or medical instruments in any way impaired, in particular should not be determined.
- the dash-dotted through the passage 4 of the sleeve seat 3 indicates the position of the cannula 16 in a sketchy manner in the sleeve seat 3.
- the embodiment according to FIG. 4 is used in particular for the intervention on breathable organs.
- the sleeve holder 1 must be understood with proper understanding of the invention as part of a comprehensive overall arrangement, which is shown in Figure 5 in a schematic diagram.
- the sleeve holder 1 with an instrument or cannula 16 received therein is mechanically connected in a manner not of further interest to a guide system 17.
- the guide system 17 allows a translatory and rotational movement and is for this purpose stored correspondingly expensive in a kind of C-arm 20 on a treatment table 21 for a patient.
- the treatment table 21 is additionally associated with an imaging system, that is, for example, a magnetic resonance tomograph 22.
- the imaging system in turn is in communication with display and control elements, such as a touch screen 23 and / or a computer with graphical user interface. Both the touch screen 23, as well as the magnetic resonance tomograph 22 is associated with a data processing system 24.
- the guiding system 17 can be operated, switched off or switched on by further operating elements, for example a foot switch 25, by the attending physician.
- the attending physician using an imaging system, such as a magnetic resonance tomograph 22, fixes the location of the puncture on the patient's body and the intervention in the patient's body and marks them on an image display of the touchscreen 23.
- the system uses the data processing system 24 to calculate the orientation of the inserted medical instrument or cannula 16 into the patient's body and accordingly controls the guidance system 17 in such a way that the patient's body automatically moves to the desired position in the required orientation starts.
- the punctuation itself then takes place as intended by the physician.
- the physician assisted by the sleeve holder 1 or another intended holding device 1, can then insert the medical instrument, for example an endoscope, or the cannula 16 described above into the patient's body to the desired insertion depth.
- the medical instrument or the cannula 16 can be decoupled from the guide system 17 or the holding device 1 at any time.
