The invention relates to a medical-technical multiple socket, in particular surgical device multiple socket, for a medical device, in particular for a high-frequency generator, for connecting a medical instrument, in particular an electrosurgical instrument. Furthermore, the invention relates to a medical device, in particular a high-frequency generator, and a medical-technical system, in particular an electrosurgical system.

Medical engineering systems particularly include the field of electrosurgical systems, which are used for example for electrosurgical cutting and / or electrosurgical coagulation. Medical systems typically include medical devices that provide an operating signal. Medical devices can be, for example, imaging devices, diagnostic devices, monitoring devices, high-frequency generators, ultrasound generators or therapy devices. Medical devices are often also designed as combination devices, two or more of the above include medical devices or their functions mentioned. In order to use medical devices, medical instruments are usually connected to the medical devices. Medical instruments may be, for example, diagnostic instruments or electrosurgical instruments.

Electrosurgical instruments are used in surgery in particular for monopolar or bipolar cutting and / or coagulation of biological tissue. The energy for the electrosurgical instrument is provided by a radio frequency (RF) generator. To such a high frequency generator different electrosurgical instruments can be connected, each providing the same or different functionalities to the user. The connected electrosurgical instruments are supplied by the high frequency generator with high frequency energy. Similarly, electrosurgical instruments can be connected to an ultrasound generator or a combined RF / ultrasound generator.

In order to connect medical instruments to medical devices, currently used medical devices generally provide different sockets for the various plugs of electrosurgical instruments. Therefore, it is common in practice that the medical devices have corresponding sockets, partially multiple sockets. In order to connect the medical instrument to a medical device, in particular to a high-frequency generator and / or an ultrasonic generator, the medical instruments usually include corresponding plugs with one or more pins, in corresponding to the medical instrument sockets on or in the medical technology Device can be introduced. By way of example, a suitable and / or specific operating signal for the connected medical instrument and / or corresponding further information can be provided via the socket.

Medical technology systems, in particular electrosurgical systems, and medical instruments, in particular electrosurgical instruments, and corresponding medical devices, in particular high-frequency generators and / or ultrasound generators, and methods are known for example from US 5,931,836 or DE 10 2009 041 329 A1. Surgery device plug and Bushings are known, for example, from DE 10 2007 061 483 A1, US Pat. No. 3,980,372 A or WO 2009/071256 A1.

The existing sockets, systems and devices offer several advantages, but further improvements are desirable. In particular, in existing solutions, errors and / or uncertainties may occur when connecting medical instruments to a medical device, which may compromise safety and / or economy, for example.

It is therefore an object of the present invention to provide a medical device multiple socket for a medical device for connecting a medical instrument, a medical device and a medical device system, which are improved over existing solutions. It is a particular object of the present invention to provide a medical multiple socket for a medical device for connecting a medical instrument, a medical device and a medical device system, which increase the security when connecting a medical instrument to a medical device and / or error possibilities when connecting reduce a medical instrument to a medical device and / or provide a simple and / or reliable and / or cost-effective solution. This object is achieved according to a first aspect of the invention by a medical-technical multiple socket, in particular surgery device multiple socket for a medical device, in particular for a high-frequency generator, for connecting a medical instrument, in particular an electrosurgical instrument, comprising an active jack with a locking sleeve, wherein the active jack is formed to receive a contact pin, a first locking sleeve, wherein the first locking sleeve is adapted to receive a contact pin, and a counter-locking element which is arranged and adapted to prevent a receiving a contact pin in the first locking sleeve in a locking position and in a release position a Allowing a contact pin in the first locking sleeve, wherein the securing sleeve is arranged and formed, by receiving a contact pin in the active bush, the counter-locking element from the locking position to bring into the release position.

In particular, when plugs with individual contact pins are inserted into such bushings of multiple bushings, which are not provided for this purpose, these disadvantages can occur. Existing solutions have therefore proposed corresponding safety plugs, which, however, usually have a very complex, expensive and / or not reliable construction. By contrast, a simple, cost-effective and reliable construction is proposed by the medical multiple bushing proposed here.

In the present application, a contact pin to be inserted into the active bushing or the blocking bushing of the medical-technical multiple bushing is preferably a component of a plug of a medical-technical, in particular electrosurgical instrument in order to connect it to a medical-technical device, in particular a high-frequency generator.

The medical multi-bushing provides that a counter-locking element prevents in its locking position that a contact pin is inserted into the locking sleeve. Only with the introduction of a contact pin in the active socket, the counter-locking element is brought into the release position by means of a correspondingly arranged and formed locking sleeve, so that the locking sleeve is receptive for a contact pin. In this way it can be ensured that only a contact pin can be inserted into the locking bush when parallel to or before a contact pin is inserted into the active jack. The use of the locking sleeve is thus prevented in a simple and reliable manner.

The spring element may have a spring tip, which preferably faces the blocking element. The spring tip is preferably formed as an edge of the spring element. The spring element may be formed, for example, sheet and / or sheet-shaped.

In a further preferred embodiment it is provided that the counter-locking element is biased in the locking position. In this way, it is ensured that the locking bush of the medical device multiple socket is locked in the starting position and can only be unlocked against a bias. The bias in the locked position is preferably applied by the spring element. In a further preferred embodiment, it is provided that the spring element, in particular a spring tip in the locking position of the Gegensperrelements with the locking element, in particular with a locking portion, is engaged.

In a further preferred embodiment, it is provided that the securing sleeve, in particular at its end facing the counter-locking element, has a run-on slope. To form a run-on slope, the securing sleeve can be chamfered, for example, at its end facing the counter-locking element. The run-on slope is preferably used to disengage the counter-locking element from the engagement with the locking element when a contact pin is inserted into the active jack. Further, it is preferred that the spring element, in particular a spring tip in the locking position of the Gegensperrelements on the locking element, in particular with a locking shoulder, and on the locking sleeve, in particular on a run-on slope, rests. Further preferably, the spring tip is biased in this voltage applied to the locking element and the locking sleeve position, further preferably by a spring force of the spring element.

In a preferred embodiment, the medical multi-bushing comprises a second locking bush, which is designed to receive a contact pin. The second Locking sleeve is preferably formed according to the first locking bushing and further preferably arranged with respect to a direction of the locking bushing shaft substantially parallel to the first locking bushing. Further preferably, the first and / or the second blocking bushing and the active bushing are arranged parallel to one another with respect to a direction of the blocking bushing shaft and / or an active bushing shaft.

Alternatively, preferably, the active bushing and / or the first locking bushing and / or the second blocking bushing has an oval or angular cross-section, wherein the corresponding contact pins then preferably also have such a geometry.

The active bushing and / or the first blocking bushing and / or the second blocking bushing are preferably arranged on a single medical-technical multiple bushing.

Preferably, the second locking sleeve has a locking element, which is arranged and designed to cooperate with the counter-locking element such that the counter-locking element in the locking position prevents movement of the locking element and in the release position allows movement of the locking element. The second blocking element is preferably designed in accordance with the first blocking element. Preferably, the locking element of the second locking sleeve encloses a part of a locking bushing shaft of the second locking sleeve. Accordingly, three or more locking bushes can be provided.

Furthermore, it is preferably provided that the blocking element of the first blocking bushing and the blocking element of the second blocking bushing are integrally formed or connected to one another. In particular, it is preferred that only one common component is provided, which serves both as a blocking element of the first blocking bushing and as a blocking element of the second blocking bushing. Preferably, such a one-piece and / or designed as a common component locking element encloses a part of a Sperrbuchsenschafts the first locking sleeve and a part of a Sperrbuchsenschafts the second locking sleeve. For example, the blocking element may be substantially cuboid and have two, preferably parallel passages. Preferably, the medical multiple socket, in particular the active bushing and / or the first locking bushing and / or the second locking bush, arranged and designed so that the first locking bush and the second locking sleeve can be used independently, provided that a contact pin is parallel or previously in introduced the active jack.

A preferred embodiment of the medical multiple bushing provides that the active bushing and the first locking bushing and the second blocking bushing are arranged such that a straight line connects centers of the active bushing, the first blocking bushing and the second blocking bushing. This embodiment therefore provides that the active bushing and the two blocking bushing are arranged in alignment, and / or the centers of the active bushing and the first and second blocking bushing lie in line. Such an arrangement allows in particular a compact design of the medical-technical multiple socket and thus a compact design of the entire medical device. Furthermore, this embodiment is particularly preferred since it is suitable for many medical technology connectors, such as connectors with one or more hand and / or finger switch contacts.

According to a further preferred embodiment of the medical multiple bush, it is provided that the first and the second blocking bush are arranged adjacent to one another. Accordingly, the first and the second blocking bushing are arranged such that no further openings or other relevant components of the medical multiple bushing are arranged between the first and the second blocking bushing. Preferably, the adjacent arrangement of the locking bush results in that both openings continue to remain integral, so that the conversions of the locking bushes have no overlap or overlaps.

In a further preferred embodiment, it is provided that the active bushing and / or the first blocking bushing and / or the second blocking bushing is or are designed as a coaxial bushing.

The coaxial socket preferably comprises an inner and an outer sleeve, which are arranged coaxially and preferably pushed into one another. The outer diameter of the inner sleeve preferably has a smaller dimension than the inner diameter of the outer sleeve. The inner diameter of the outer sleeve is preferably larger than the outer diameter of the inner sleeve. Between the inner and the outer sleeve, an outer, annular Koaxialbuchsenoffnung is formed. Inside the inner sleeve, an inner Koaxialbuchsenoffnung is formed.

The coaxial socket is in particular designed to receive a coaxial plug element, the coaxial plug element preferably having an inner contact pin and an outer contact ring. The outer contact ring preferably has an inner recess in which the inner contact pin is arranged. A coaxial connector between the coaxial jack and the coaxial jack typically occurs by inserting the inner contact pin into the inner coaxial jack opening and the outer contact ring into the outer annular coaxial jack opening. The coaxial connector thus obtained has the advantages of a very low electromagnetic interference and radiation and a good electrical shielding. Furthermore, there is the possibility of using the coaxial jack only with a contact pin which is guided in the inner Koaxialbuchsenoffnung the coaxial socket.

In a preferred embodiment of the medical multiple bushing, this comprises a positioning opening, which is designed to receive a positioning pin. Preferably, the positioning opening usually provides no electrical function or no primary electrical function, but serves above all the safe and correct positioning of the plug in the desired position in the medical multiple socket. Especially with plugs that would allow more than one way of positioning in the socket without a locating pin, a locating pin and a corresponding locating hole are advantageous in order to achieve unambiguous positioning of the connector in the medical multiple socket. Alternatively or additionally, the positioning opening can also be used to make a grounding contact.

Orthogonal to an axial extent, the cross-section of the positioning opening is preferably substantially circular. There is also the possibility that the positioning opening has an oval or polygonal cross section, for example a triangular or rectangular or quadrangular or polygonal cross section.

In a further preferred embodiment of the medical multiple bush, it is provided that a center point of the positioning opening, spaced from a straight line, connects the centers of the active bushing and the first blocking bush, and possibly the second locking bush, is arranged. Preferably, the straight line connecting the centers of the active bushing, the first locking bushing and / or the second locking bushing does not pass through the center of the positioning hole. The positioning opening is therefore preferably not in alignment with the active bushing and the first blocking bush, and possibly the second blocking bush, the medical-technical multiple bushing. This non-aligned positioning opening has the particular advantage that thereby a secure and unambiguous positioning of a plug is improved.

According to a further preferred embodiment of the medical multiple bush, it is provided that a distance between a center axis of the first blocking bushing and a center axis of the second blocking bushing is smaller, preferably many times smaller, than a distance between the center axis of the first blocking bushing and a center axis of the active bushing, and / or a distance between the central axis of the second locking sleeve and the center axis of the active bushing, wherein preferably the distance between the central axis of the first locking sleeve and the center axis of the active sleeve is greater than the distance between the central axis of the second locking sleeve and the center axis of the active sleeve.

This arrangement results in that there is an area in which the active jack is arranged, and a second area in which the locking jacks are arranged. While both regions have a comparatively small extent, there is a large spacing between these two regions relative to the extent of these regions. It is preferred that the distance between the first blocking bushing and the active bushing has the largest spacing between two openings on the medical-technical multiple bushing. Moreover, it is preferred in this embodiment that the positioning opening between one of the locking bushes and the active jack is arranged. Furthermore, it may be preferred that the positioning opening is arranged between the region in which the active bushing is arranged and the region in which the blocking bushes are arranged

In a further embodiment of the medical multiple bush, it is provided that the distance between the central axis of the first blocking bushing and the center axis of the second blocking bushing is at most 10 times the diameter of the first and / or second blocking bushing. Particularly preferred is a maximum distance of 7.5 times the diameter, moreover, a distance which is at most 5 times the diameter is also preferred. In another particular preferred embodiment, the distance between the two locking bushing is at most twice the diameter of the first and / or second locking bushing.

In a further preferred embodiment, the distance between the locking bush between 6 and 7 mm, preferably 6.58 mm. In a particularly preferred embodiment of the medical device multiple bushing is provided that the central axis of the active bushing and the central axis of the second locking sleeve have a distance of 28-29 mm, in particular 28.58 mm to each other. Such a spacing allows the use of a plug with two contact pins whose center axes have a spacing of 28 mm to 29 mm, preferably 28.58 mm. Such connectors are often used in electrosurgery, so that this embodiment in particular increases the compatibility of a high frequency generator comprising such a medical multiple socket.

A further preferred embodiment of the medical multiple bushing provides that the center axis of the active bushing and the center axis of the first blocking bushing have a distance of 21-23 mm, in particular 22 mm, from each other. Such a spacing of the active bushing and the first blocking bushing makes it possible to use a plug which has two contact pins with a spacing of 21-23 mm, in particular 22 mm, from one another. Such connectors with contact pins having the aforementioned spacing are also often used in electrosurgery.

This arrangement of the active bushing and the first locking bushing, as well as the previously described arrangement of the active bushing and the second blocking bushing, shows the flexibility of the medical-technical multiple bushing present here. The compact arrangement of the active jack and the first and second locking sleeves allows a plug with a contact pin spacing of 21-23 mm and a plug with a contact pin spacing of 28-29 mm, and preferably also a coaxial plug element, to be connected to this compact medical multi-socket are. Preference is given to a medical-technical multiple socket, in particular a surgical device multiple socket for a medical device, in particular for a high-frequency generator, for connecting a medical instrument, in particular, an electrosurgical instrument comprising an active jack with a locking sleeve, the active jack adapted to receive a contact pin, a first locking sleeve, the first locking sleeve adapted to receive a contact pin, and a counter-locking member disposed and formed in a locking position to prevent receiving a contact pin in the first locking sleeve and to allow in a release position a recording of a contact pin in the first locking sleeve, wherein the locking sleeve is arranged and formed by receiving a contact pin in the active jack, the locking element from the locking position to the release position bring. According to a further aspect of the invention, the object mentioned at the outset is achieved by a medical device, in particular a high-frequency generator comprising a medical multiple socket, in particular a surgical device multiple socket, according to one of the previously described embodiments.

In the figures, identical or substantially functionally identical or similar elements are designated by the same reference numerals. The exemplary embodiment illustrated in FIGS. 1 to 10 shows a surgical device multiple socket designed as a medical multiple socket 100 for a medical device, in particular for a high-frequency generator, for connecting a medical instrument, in particular an electrosurgical instrument.

FIGS. 1 to 10 show an exemplary embodiment of a surgical device multiple bushing 100 in different views and sections.

The medical-technical multiple bushing 100 has a front plate 140 with an active bushing 1 10, a first blocking bushing 130 and a second blocking bushing 120. Furthermore, the medical-technical multiple bushing 100 has a counter-locking element 300. The active jack 1 10 is formed in this embodiment as a coaxial socket, but other configurations are possible.

The active bushing 1 10 has an active bushing shaft 1 1 1 and a securing sleeve 210, wherein the securing sleeve 210 engages around a portion of the active bushing shaft 1 1 1. The securing sleeve 210 has on its counter-locking element 300 facing the end of a run-on slope 21 1, which is formed by a chamfered end of the securing sleeve 210. The run-on slope 21 1 serves to disengage the counter-locking element 300 from the engagement with the blocking element 220 when a contact pin is inserted into the active bushing 1 10. The locking sleeve 210 is relatively movable to the Aktivbuchsenschaft 1 1 1 and the Sperrbuchsenschaft 131 and the locking element 220 and the counter-locking element 300 is arranged.

The first blocking bushing 130 has a blocking bushing shaft 131, likewise the second blocking bushing 120 has a second blocking bushing, which can not be seen in the figures. The two Sperrbuchsenschafte encompassing an integrally formed locking element 220 is arranged with a locking shoulder 221 at its the locking element 300 facing the end.

In Figures 1, 3, 5, 7 and 9, the surgical device multiple bushing 100 is shown with the counter-locking element 300 in the locked position. In FIGS. 2, 4, 6, 8 and 10, the surgical device multiple bushing 100 with the counter-locking element 300 in the release position is shown.

The blocking element 220 is arranged and designed to cooperate with the counter-locking element 300 such that the counter-blocking element 300 prevents a movement of the blocking element 220 in the blocking position and allows movement of the blocking element 220 in the release position.

The blocking element 220 is movable relative to the blocking bushing shaft 131, in particular in the form of a translatory movement along a longitudinal direction and / or longitudinal axis of the blocking bushing shaft 131. The blocking element is also relatively movable to the securing sleeve 210, in particular also in the form of a translational movement along a longitudinal direction and / or longitudinal axis of the Sperrbuchsenschafts 131 and or Aktivbuchsenschafts 1 1 1. Preferably, the locking member 220 is arranged and configured to be set in motion by inserting a contact pin into one or both of the locking sleeves 120, 130, preferably into substantial translational movement in a direction parallel to a longitudinal axis and / or longitudinal direction of the locking sleeve shaft 131, provided that the counter-locking element 300 is in the release position.

The locking element 220 has a locking shoulder 221, in which a spring tip 321 of the spring element 320 of the Gegensperrelements 330 can engage in order to prevent the movement of the locking element 220 can. The spring element 320 is arranged on a base body 310 of the counter locking element 330, at the (in the installed state) upper end. As can be seen in FIGS. 1-4 and 7-10, the spring element 320 is designed to be curved in cross section, parallel to a receiving direction of contact pins, and in a side view. The spring tip 321 is sheet-shaped and / or sheet-shaped and facing the blocking element 220. The spring tip 321 is formed as an edge of the spring element 320.

The spring tip 321 spring tip is in the locking position of the Gegensperrelements 300 with the locking shoulder 221 into engagement. The spring tip 321 is in the locking position of the Gegensperrelements 300 to the locking shoulder 221 and the stop bevel 21 1 of the locking sleeve 210 at. The counter-locking member 300 is biased by the spring force of the spring member 320 in the locking position. In this way, it is ensured that the locking bushes 120, 130 of the surgical device multiple bushing 100 are locked in the starting position and can only be unlocked against a bias voltage.

The securing sleeve 210 has a securing inner sleeve 212. The inner locking sleeve 212 can be connected via a locking pin, which is inserted into the locking pin 213, with the locking sleeve 210, so that an inserted into the active jack 1 10 contact pin not only the inner sleeve 212, but also the locking sleeve 210 along the Aktivbuchsenschafts 1 1 1 moves , Accordingly, the blocking element 220 has a locking element inner sleeve 222 for the blocking bushing 130. An analogous embodiment, the locking element 220 for the locking sleeve 120, which is not visible in the figures. The Locking element inner sleeve 222 can be connected to locking element 220 via a locking pin which is inserted into locking pin opening 223, so that when inserting contact pins into locking sleeves 120, 130 not only locking element inner sleeve 222, but the entire locking element 220 is moved along locking sleeve shaft 131 , For this purpose, the Sperrbuchsenschaft 131 has a corresponding slot 132 through which a locking pin can be moved. It can not be seen in the drawings that preferably also have the Sperrbuchsenschaft the second locking sleeve 120 and the Aktivbuchsenschaft 1 1 1 corresponding slots.

Prerequisite for the movement of the locking element 220 is that the counter-locking element 300 is brought by a corresponding movement of the securing sleeve 210 via the starting slope 21 1 of the locking position in the release position.

The surgical device multiple bushing 100 further includes a positioning aperture 150. The positioning opening 150 is not on the connecting line connecting the centers of the locking sleeves 120, 130 and the coaxial jack 1 10, so that the positioning hole 150 is not in alignment with the first and second locking sleeve 120, 130 and the coaxial jack 1 10. The positioning aperture 150 may be for receiving a locating pin to prevent mispositioning of a connector relative to the surgical device hub 100. The active bushing 1 10, the locking bushes 120, 130 and the positioning opening 150 are recessed at an inner recessed portion 141 of the front panel 140 of the surgical device multiple bushing 100. An outer, also recessed mounting portion 142 with a plurality of openings 143 serves to attach the surgical device multiple socket 100 to a medical device.

The surgical device multiple bushing 100 thus provides that the counter-locking element 300 in its locking position prevents a contact pin from being inserted into the locking bushes 120, 130. Only with the insertion of a contact pin in the active jack 1 10 21 of the locking sleeve 210, the counter-locking member 300 is brought into the release position by means of the contact slope 21, so that the locking sleeves 120, 130 are receptive for pins. In this way it can be ensured that only a contact pin can be inserted into one or both locking sleeves 120, 130, when a pin is inserted into the active bushing 1 10 in parallel. The usage only the locking sleeves 120, 130 is thus prevented in a simple and reliable manner.

In addition, the surgical device multiple socket 100 has a simple and inexpensive as well as reliable construction, whereby a compact design of medical devices can be realized.
