Description

  • The The invention relates to a surgical instrument with a proximal and a distal end, with a first tool and a second, relative to the first movable tool at the distal end of the instrument, with a first fluid channel associated with the first tool, the a fluid inlet has its proximal end and a fluid flow in allows distal direction, and with a second fluid channel, which is a fluid flow in the proximal direction allows and a fluid outlet its proximal end, wherein the first tool the second Fluid channel includes.
  • Surgical instruments of the type described above are for example from the US 5,417,709 known. This discloses, for example, an endoscopic bipolar scissors, along the shaft of each other separately, a suction and a flushing channel are provided. Tools pivotable at the distal end of the instrument are provided with discharge ports which are in fluid communication with either the purge or suction channels, respectively.
  • To the become deserted of soft tissue is usually over two Electrodes applied a high frequency current. This can be done directly over the Instrument or over separate electrodes flow. In both cases If the instrument is in contact with such a coagulation area, with the result that the both tools get very hot can.
  • With the two in the bipolar scissors according to the US 5,417,709 provided flushing and suction ducts is in principle a cooling possible, but this configuration has several disadvantages. On the one hand, rinsing fluid escapes from the instrument in the operating area, so that losses of fluid must be expected, and therefore not every fluid can be used as a cooling fluid. On the other hand, the suction channel can become blocked if tissue parts are extracted with suction.
  • From the US 5,300,087 is a multi-functional pliers known. In the US 4,096,864 is described a fluid-conducting surgical instrument in the form of forceps. In the US 4,049,002 a fluid-conducting surgical instrument is disclosed. The US 6,183,433 B1 deals with a surgical suction and cutting instrument with internal flushing. In the DE 692 11 950 T2 a handpiece for an ultrasonic device is described. The DE 44 29 260 A1 discloses a surgical bipolar instrument. From the US 6,102,885 a device for liposuction and a method for using the same is described. The DE 200 08 623 U1 deals with a scissors or forceps-shaped surgical instrument. Another surgical bipolar scissors is in the DE 298 21 617 U1 disclosed. And finally, in the US 5,658,281 a bipolar electrosurgical scissors and a method for producing such a described.
  • Therefore It is an object of the present invention, an instrument of the beginning described type to improve the tools in a simple manner and reliable chilled can be.
  • These Task is in a surgical instrument of the type described above Type according to the invention thereby solved, that the first fluid channel and the second fluid channel a cooling channel form and that one distal end portion of the first fluid channel having a distal end portion the second fluid channel is in direct fluid communication by the two distal ends of the fluid channels are interconnected, so that one Cooling circuit in the cooling channel by means of a fluid flowing through the first and second fluid channels arises.
  • By the direct fluid connection of the two distal end portions of the two fluid channels no fluid can enter the operating area anymore. The easiest The direct fluid connection is made by placing the two distal ones Ends of the fluid channels be connected to each other. By the arrangement of the two fluid channels on one Tool thus creates a closed cooling circuit. impurities can do not penetrate into these and clog the cooling channel. So that can a tool can be safely cooled. In the same way could Also, the second tool to be provided with a cooling channel. Further would be the two fluid channels in the field of tools connecting cross channels to further improve the cooling conceivable.
  • Preferably are the fluid inlet and / or the Fluid outlet in arranged a tool-free area of the instrument. On the Fluid inlet and the Fluid outlet is the cooling channel connectable with a fluid supply or -absaugung. The order the two connections in a tool-free area of the instrument has, for example in endoscopic instruments the advantage that the connections on the instrument can be arranged that she to be outside the human body during a surgical procedure can and do not unnecessarily restrict the operation area.
  • In a preferred embodiment of the invention, it may be provided that the first and second fluid channels extend substantially from the proximal to the distal end of the instrument and that the fluid inlet and outlet are located at the proximal end of the instrument. In this way, particularly slim instruments can be formed which can preferably be used in endoscopy. Furthermore, the handling of the instrument is facilitated since no interfering connections for a fluid to be supplied or removed have to be arranged in a handle or tool area of the instrument.
  • Cheap is it, when a distance between the first and the second fluid channel is greatest in the area of the first tool. By the big distance the two fluid channels the first tool can be cooled optimally and heat can be dissipated from this over a large area.
  • In principle, it would be conceivable to design the surgical instrument also as a tubular shaft instrument. However, it is advantageous if the surgical instrument two includes relative to each other pivotally mounted to each other industries and if each of the two distal ends of the branches of one of the two tools includes. For example, the instrument may be in the form of a conventional one Scissors be configured with one or both fluid channels in or arranged on one of the two branches.
  • Around It can facilitate the formation of the two fluid channels Cheap be when the first tool is designed in several parts and at least one comprises first and a second tool element. So one or both fluid channels can partially be formed in one of the two tool elements. Further is it is possible to use different materials, such as an abrasion resistant metal for a cut shaped Tool and a plastic for a fluid channel. Also, ceramic tool elements are conceivable.
  • According to one preferred embodiment of Invention the first tool element the first and / or the second fluid channel at least partially. It is therefore possible, the fluid channel or the two fluid channels also to design in one piece, for example as a pipe.
  • Advantageous but it can also be when the first and the second tool element the first and / or the second fluid channel at least partially include. Both tool elements can help in the formation of the two fluid channels interact by, for example, adding each element to a half-shelled one Recess is provided.
  • The two fluid channels could completely within be arranged one of the two Werzeugelemente. Cheap is However, if the first and the second tool element to each other adjacent and when the first and / or the second fluid channel along an interface run between the first and the second tool element. Thereby the production of the tool elements is considerably simplified. Parts of the two fluid channels can each be incorporated into the two tool elements, which then together brought be and together form the two fluid channels. It would also be conceivable a tubular Lead along the interface to arrange between two tool elements.
  • Especially the structure becomes simple when the first and / or the second tool element are each provided with a recess for common education the first and / or second fluid channel. Both tool elements can prepared separately from each other to form a fluid channel become. Other parts are not necessary.
  • Especially It is advantageous if the first tool element consists of an insulator, in particular a ceramic material is produced. This can be For example, insulation between the first and second tools when the first tool element made of an insulator adjacent to the other of the two tools. Also can do with it electrical conductor completely isolated in the area of the first tool become.
  • Preferably is the second tool element made of a metal, in particular from a highly conductive Made of metal. Especially when acted upon by electricity Instruments is a reliable one electrical conductor of advantage, in particular the heating of the Instruments to keep low.
  • For a lasting stability of the instrument, it is advantageous if the first and the second Tool element are connected together, in particular glued or soldered. Such compounds are also between different materials possible. Across from a connection by cladding by means of a further tool element can when gluing or soldering it Completely be waived.
  • Especially Cheap it is when the first and / or the second tool element at least partially covered with a cover layer. This can be especially interfaces or protect connection edges. This is especially true in sterilization procedures involving the surgical Instrument will usually be subject, indispensable. In addition, can a cover layer are also formed as an insulating layer. The cover layer is particularly simple and advantageous when passing through Injection of a plastic is produced.
  • Around a safe flow of the fluid in the fluid channels to ensure, comprises at least a portion of the first and / or the second fluid channel a pipe. This can be avoided that, for example, due to Gluing or soldering of two tool elements closed a fluid channel during manufacture becomes.
  • According to one preferred embodiment of Invention may be provided that the first and the second Fluid channel in a region of the first tool substantially are arranged in a mold plane, that the first and the second fluid channel outside the area of the first tool substantially in a feed level are arranged, which extends substantially transversely to the tool level. With This arrangement can be achieved in particular a slim design become, what for endoscopic instruments is beneficial. In addition, this embodiment allows that, for example in a two swiveling industries comprehensive scissors connections of two fluid channels protrude transversely to the plane of the scissors and so a movement of the second Industry relative to the first industry.
  • A Rotation of the feed line and the tool level can be, for example can be achieved by the two fluid channels are curved accordingly. Cheap However, it is when a two-chamber fluid distribution chamber in a transition area between the first tool and a tool-free area, when the Fluidverteilkammer two parallel to the tool level and comprises two aligned parallel to the feed line connections and if one of the two sub-chambers a fluid connection between one parallel to the tool level and one parallel to the feed level aligned connection forms. In this way, complicated and the fluid channels in their stability hazardous Bie ments same avoided. The fluid channels can be directly on both sides of the Fluid distribution chamber are connected.
  • to Training the instrument as a monopolar and / or bipolar instrument it is advantageous if the first and the second tool electrically against each other are isolated. This avoids unwanted short circuits. Coagulation of soft tissue by application of a high frequency current to the instrument is possible in a simple manner.
  • Especially Cheap it is when the first branch has a first electrical lead comprises which is related to the first tool, and if at the first or the second branch a second, from the first electric insulated electrical supply line is provided, which is connected to the second Tool communicates. That way, a stream can be easy and safely routed to the two tools, for example to drive the tool or to coagulate soft tissue.
  • Basically It is advantageous if the two fluid channels are connected to each other are that no Fluid can leak. However, it can be beneficial if at least one of the two fluid channels is provided in its distal end with openings. The two fluid channels serve on the one hand as a cooling channel, on the other hand as a flushing channel for do the washing up an operating area with a suitable rinsing liquid.
