Description
Technical Field
The invention relates to a puncture device comprising a puncture cannula, wherein the proximal end of the puncture cannula facing the body is arranged to penetrate into a body cavity and/or to create a passage to a body cavity or tissue area. Furthermore, the invention relates to a device for irradiating tissue and to a medical kit.
Background
A large number of such puncturing devices are known. They are used in particular for opening body cavities or for removing tissue from the body of a patient. Furthermore, with the channel thus produced, the possibility exists of introducing minimally invasive instruments into the human body. This also relates in particular to a light guide or a light guide bundle connected to the illumination device. Depending on the type of light emitted, it may be merely necessary to irradiate the body tissue, for example in order to calculate autofluorescence tissue, or else to cut or coagulate tissue by means of a laser beam.
However, the known puncturing devices have the disadvantage that with these known puncturing devices it is always necessary to carry out two operating steps, namely first the production of a channel into the body and the subsequent introduction of a minimally invasive instrument, such as, for example, a light guide or a light guide bundle. The multiple introduction of the instrument represents a non-negligible health burden or a non-negligible surgical risk for the patient, since this, for example, multiplies the risk of infection. In addition, the introduction of the light conductors or light guide bundles can also lead to damage, in particular to damage of the proximal end of the light conductors or light guide bundles, i.e. the end facing the human body.
Disclosure of Invention
It is therefore an object of the present invention to provide a puncturing device of this type, a device for irradiating tissue of this type, and a medical kit of this type, which ensure better minimally invasive surgery and furthermore prove better protection against damage.
A puncture device according to the features of claim 1, a device for irradiating tissue having the features of claim 11 and a medical kit having the features of claim 13 are used for this purpose.
Advantageous designs are described in each of the dependent claims, wherein an advantageous design of each aspect of the invention can be regarded as an advantageous design of the respective other aspect of the invention and vice versa.
A first aspect of the invention relates to a puncturing device comprising a puncturing cannula, wherein a proximal end of the puncturing cannula, which is close to a body, is arranged to penetrate into a body cavity and/or to create a passage to a body cavity or tissue area.
According to the invention, at least one light guide or at least one light guide bundle is arranged in the puncture cannula, wherein the light guide or the light guide bundle and the puncture cannula are designed to be longitudinally movable relative to one another. By arranging the light guide or the light guide bundle in the puncture cannula, it is possible to carry out minimally invasive treatments in one method step. The light guide or the light guide bundle arranged in the puncture cannula is introduced into the body at the same time as the penetration into the body cavity or the passage to the body cavity or tissue region of the patient takes place. By means of the relative longitudinal displaceability of the puncture cannula with respect to the light guide or light guide bundle, the puncture cannula can be at least partially retracted, i.e. displaced in the direction of the distal end of the light guide remote from the body, after a correct positioning of the puncture device. The proximal end of the light guide or of the light guide bundle, which is close to the body, is then exposed in the body cavity or corresponding tissue area to be irradiated and/or treated. Thus, the separate introduction of the light guide or the light guide bundle can be reliably avoided, and the puncturing device according to the invention thus allows for better minimally invasive surgery. In an advantageous embodiment of the puncture device according to the invention, the proximal end of the light guide or of the light guide bundle, which is close to the body, does not protrude from the proximal end of the puncture cannula in the first non-use state. In a second activated state, the proximal end of the light guide or the light guide bundle projects from the proximal end of the puncture cannula. It is thereby ensured that the proximal end of the light guide or the light guide bundle is at least partially surrounded by the puncture cannula during the process of introducing the puncture device into a body cavity or a tissue region. This ensures a better protection of the proximal end of the light guide or the light guide bundle, in particular, close to the human body, against possible breakage during the process of making a passage to a body cavity or during the process of introducing the puncture device into the body cavity or a corresponding tissue region.
In a further advantageous design of the puncture device according to the invention, the proximal end of the puncture cannula is designed to taper in the proximal direction. In addition, the proximal end of the puncture cannula may be designed as a pointed tip. Furthermore, there is the possibility that said proximal end of said puncture cannula comprises at least one blade. By these measures it is ensured that the puncture device can of course create a passage to the body cavity or to the tissue region to be examined or treated. Typically, the puncture cannula additionally has a hollow cylindrical cross-section. It is of course also possible for the puncture cannula to be formed by a bundle of hollow cylindrical cannulae.
In a further advantageous embodiment of the puncturing device according to the invention, the puncturing sleeve consists of metal, metal alloys, in particular medical steel, silicon, plastic or a combination of at least two of these materials. Other materials suitable for medical use are also contemplated.
In a further advantageous embodiment of the puncturing device according to the invention, the proximal end of the light guide or of the light guide bundle, which is close to the body, is surrounded by a substantially cylindrical housing, wherein the housing is made of a material that is permeable to laser light. By arranging such a casing, an additional protection of the proximal end of the light guide or the light guide bundle against breakage is formed. Furthermore, it is possible to arrange at least one beam deflection device at or in the proximal end of the light guide or light guide bundle for deflecting the light arriving from the light guide or light guide bundle into the surrounding tissue. This results in particular in laser applications, since the laser beam can be directed exactly at the tissue to be treated around the proximal end of the light guide or the light guide bundle.
In a further advantageous embodiment of the puncturing device according to the invention, at least one position marking is provided on the puncturing cannula and/or the light guide bundle for indicating the current position of the puncturing cannula with respect to the light guide or the light guide bundle. The position marking can in particular be provided in a distal region of the light guide or light guide bundle and/or of the puncture cannula remote from the body. This provides a simple and readily available control of the position of the puncture cannula relative to the position of the light guide or light guide bundle for the user of the puncture device.
In particular, when the puncture cannula is retracted and the proximal end of the light or light guide bundle is exposed, the length of the retraction stroke can be defined and determined exactly.
A second aspect of the invention relates to a device for irradiating tissue, comprising at least one light source and a penetration device as described above. Wherein at least one light conductor or at least one light-conducting bundle is coupled to the light source at a distal end remote from the body for feeding light. Further, the light source may be an LED light source or a laser light source. When using a laser light source, the device is designed for laser ablation of tissue. The features thus obtained and the advantages thereof will be evident from the description of the first aspect of the invention.
A third aspect of the invention relates to a medical kit comprising at least one puncturing device as described above. The medical kit additionally comprises a puncture template, wherein the puncture template has at least one opening for the passage of the puncturing device. In particular, the use of a puncture template allows for a more accurate positioning of the puncture device when making a passage into a body cavity or tissue to be examined and/or treated of a patient. Further features of the third aspect of the invention and advantages thereof will be apparent from the description of the first and second aspects of the invention.
Drawings
Further features of the invention emerge from the claims, the embodiments and the figures of the drawing. The features and feature combinations mentioned above in the description and in the following exemplary embodiments are not intended to be restricted to the respective combinations specified, but can also be used in other combinations or on their own, and are within the scope of the invention. Wherein:
fig. 1 is a schematic illustration of a puncturing device according to the invention in a first, non-use state;
FIG. 2 is a schematic illustration of a puncturing device in accordance with the invention in a second activated state; and
fig. 3 is a schematic illustration of a device for irradiating tissue according to the present invention.
Detailed Description
Fig. 1 shows a schematic representation of a puncturing device 10 in a first non-use state. The first non-use state means that the light guide guided in the puncture cannula 12 of the puncture device 10 does not protrude from the proximal end 14 of the puncture cannula 12 with its proximal end 20 close to the body. However, it is possible that in the first non-use state light is already coupled into the light guide 18, for example, in order to illuminate the environment around the proximal end 14 of the puncture cannula 12 close to the human body. As can be seen, the proximal end 14 of the penetrating cannula 12, which is proximal to the body, is configured to penetrate a body cavity and/or to create access to a body cavity or tissue region 16. In the shown embodiment, the proximal end 14 of the puncture cannula 12 is designed to taper in the proximal direction, in particular the proximal end 14 of the puncture cannula 12 is designed as a pointed tip. Furthermore, there is the possibility that the proximal end 14 of the puncture cannula 12 comprises at least one blade.
It can also be seen that the light guide 18 is arranged within the puncture cannula 12, wherein the light guide 18 and the puncture cannula 12 are designed to be longitudinally displaceable relative to one another. In the exemplary embodiment shown, the puncture cannula 12 is displaceable relative to the light guide 18, in particular in the direction indicated by the displacement arrow 40, by means of a handle element 34 which is arranged on the distal end 32 of the puncture cannula 12 facing away from the body. The movement arrow 40 is in this case directed in the direction of the distal end 30 of the light guide 18 facing away from the human body.
In addition, as can be seen in FIG. 1, the proximal end 20 of the optical conductor 18 is at least partially surrounded by the proximal end 14 of the puncture cannula 12. It is also apparent that the proximal end 20 of the optical waveguide 18 is surrounded by a substantially cylindrical jacket 22, wherein the jacket 22 is made of a laser-transparent material. In addition, a beam deflection device (not shown) is arranged on or in the proximal end 20 of the light guide 18 for deflecting the light arriving from the light guide 18 into the surrounding tissue 16.
In the illustrated embodiment, the puncture cannula 12 has a hollow cylindrical cross-section. The puncture cannula 12 is furthermore made of a metal alloy, in particular medical steel. Other materials and combinations of materials are also contemplated.
In the exemplary embodiment shown, the puncture cannula 12, as it were also the optical waveguide 18, has a position marking 24 in each case for indicating the current position of the puncture cannula 12 relative to the optical waveguide 18. Furthermore, both on the puncture cannula 12 and on the light guide 18, a plurality of markings, for example, millimeter marks, can be provided.
Fig. 2 shows a schematic representation of the puncturing device 10 according to fig. 1 in a second activated state. The second activation state is a state in which the proximal end 20 of the light guide projects from the proximal end 14 of the puncture cannula 12. In this state, the surrounding tissue 16 may be fully illuminated without the proximal end 14 of the puncture cannula 12 interfering with the optical path. This is particularly important when fluorescence imaging is possible or when laser ablation of the tissue 16 is concerned. It can be seen that in the second activated state, the puncture cannula 12 will be moved in the proximal direction (see movement arrow 40 in more detail). Irradiation or ablation of the tissue region 16 is performed through the proximal end 20 of the optical conductor 18. The initiation of such minimally invasive examination or treatment merely requires retraction of the proximal end 14 of the puncture cannula 12.
Fig. 3 shows a schematic illustration of a device 26 for irradiating tissue 16. In the illustrated embodiment, the device 26 includes a laser light source 28 and the lancing device 10. The design of the puncturing device 10 conforms to the design as illustrated in fig. 1 and 2. It can also be seen that the light conductor 18 engages the light source 28 at a distal end 30 remote from the human body in order to feed the laser light. The device is designed according to the present embodiment for laser ablation of tissue 16.
