Definitions
- the invention relates to an electrosurgical laparoscopic instrument according to the preamble of claim 1.
- the object of the present invention is to provide a generic instrument with simpler design and constant handling conditions.
- conduits are arranged in the wall of a hose which, surrounding the rod, is arranged in the tube, that is to say that it lies symmetrically with its wall between the rod and the tube.
- the electrical wires are embedded in the wall material of the hose, z. B. poured. They are well protected in this way against friction between the rod and tube.
- Such a hose can be inexpensively manufactured with techniques common in cable insulation. He can be formed rotationally symmetrical surrounding the rod with a constant wall thickness, so that there are always constant friction and handling conditions under all handling conditions.
- the construction according to the invention is thus also suitable for heavily loaded pliers which are intended to apply high closing forces and, in particular, also for pliers with a bent shaft, in which the rod strikes the pipe in the bent part with high force.
- the features of claim 2 are provided.
- the friction between the rod and tube can be improved, which is a considerable advantage especially in the transmission of high forces in a curved shaft and significantly improves the operation and the controllability of the operation.
- the tube may be immovably against the tube or rod, e.g. B. be secured by very high coefficients of friction or by gluing or the like. Movement then only takes place between the hose and the other shaft element, namely the Rod or pipe instead. As a result, the movement conditions and the friction conditions are made clearer and also the electrical contacting problems at the ends of the hose are simplified. If the hose is firmly connected to the pipe, for example, then the ends of the electrical lines are fixed relative to the pipe. In the other case, the ends of the lines are fixed relative to the rod, if this is more advantageous for Maisticians sectionen.
- FIG. 1 is a side view of an instrument according to the invention with curved shaft
- Fig. 2 is a section along line 2 - 2 in Fig. 1 and
- Fig. 3 shows a section corresponding to FIG. 2 by an embodiment variant.
- FIG. 1 shows an electrosurgical laparoscopic instrument in the form of a forceps 1 with an elongated, bent in the distal end portion formed as a tube shaft 2 and attached to the distal end of the tube 2, designed as a forceps jaw 3 end effector and one at the distal end of the tube. 2 attached handle 4.
- the forceps jaw 3 has two closed jaw parts 5, which are shown closed against one another and designed to be pivotable relative to one another.
- On the handle 4 two provided with the usual finger rings relative to each other movable grips 6 are mounted.
- the grips 6 of the handle 4 are coupled via a arranged in the interior of the tube 2, this longitudinally passing rod 7, which is shown in Fig. 2, coupled to the rod mouth 3, to effect the relative movement of the jaws 5.
- the instrument is designed as a forceps 1, wherein the jaws 5 are formed as a pair of tongs.
- the instrument can also be designed as a pair of scissors, the jaws 5 being designed as scissor blades.
- the illustrated pliers 1 may be formed in a manner not shown with a straight tube 2, which runs straight between the handle 4 and forceps jaw 3.
- the tube 2 is rigid.
- the forceps 1 is designed for use with another laparoscopic instrument in a common port, as described in DE 20 2009 007 592 U.
- the tube 2 as shown in Fig. 1, is formed bent in its distal region.
- At least one electrode is provided in the forceps 1 on the forceps jaw 3. It may also be an execution with multiple electrodes z. B. in multipolar technology, optionally in pulsed operation with different polarity to supply.
- the two jaw parts 5 may be formed as electrodes.
- H nzu sensors can come as z. B. thermosensors, which are also supplied with electrical lines. It may therefore be necessary in the pliers 1 to move through the tube 2 through a larger number of electrical lines.
- the invention provides for this purpose, as shown in Fig. 2, a hose 8, which is arranged in the tube 2, this longitudinally passing, and the rod
- the tube 8 may, for. B. of suitable plastic, such as PTFE (polytetrafluoroethylene).
- suitable plastic such as PTFE (polytetrafluoroethylene).
- Several electrical lines 9, in the drawing example of FIG. 2 are (for explanatory purposes) eight lines 9, are rotationally symmetrical in cross-section in the wall material of the tube 8, z. B. poured.
- the tube 8 is the tube 2 fitting and formed with some play against the rod 7.
- the tube 8 can be attached to the tube 2, z. B. due to heavy friction or by gluing or the like. Opposite the rod 7 very good friction conditions are preferably chosen, so that low friction occurs here.
- the section of FIG. 2 is, as shown in FIG. 1, chosen at the location of strong curvature of the tube 2. At high closing force of the forceps 1, so if the rod 7 has to transmit a high tensile force, the rod 7 sets the side of the tube 2, as shown in FIG. 2.
- the tube 8 between rod 7 and tube 2 can lead to favorable coefficients of friction here.
- Fig. 3 shows a variant in which the same reference numerals are used.
- the hose In contrast to the imple mentation form of Fig. 2 here is the hose
- the tube 2 may be straight. A bendable with force construction of the tube 2, which remains sufficiently rigid when actuated, is conceivable for these purposes.
- the rod 7 may be a solid wire rod, but is, in particular for the purposes of the bent tube 2 of Fig. 1, better designed as wire helix, wherein, in a manner not shown, the rod 7 has a central wire core, are wound opposite to the two wire helices , Such a construction is well bendable and also suitable for the transmission of rotational forces.
- the forceps jaw 3 can be designed to be rotatable relative to the tube 2.
- a rotary actuator is provided, with the rotation of the forceps jaw 3 is effected.
- the rotation transmission from the handle 4 to the forceps jaw 3 can, for. B. via the rod 7, which is then preferably formed as mentioned above with cross-wound wire windings.
- the rotary operation can also be done in an advantageous manner via the tube 8, which may be suitably designed torsionally rigid, z. B. in turn can be reinforced with cross-wound wire helices.
- the lines 9 in the tube 8 are contacted in the forceps jaw 3 in a suitable manner with there provided electrodes, sensors and the like. Depending on the construction, it may be more advantageous to firmly connect the tube 8 according to FIG. 2 to the tube 2 or, according to FIG. 3, firmly to the rod 7.
- the hose 8, z. B. are led out laterally from the handle 4 to continue from there to a control and supply unit. It can also handle contacts 4 plug contacts be provided, which are further connected with a plug and connection cable, not shown.
- all extending between the forceps jaw 3 and handle 4 lines 9 are arranged in the wall of the tube 8.
- lines of a different design may also be provided, e.g. in the form of electrically conductive coatings of the tube 2.
- rod 7 and the tube 2 are used as additional electrical conductors or in the interior of the tube 2 in addition to the tube 8 laid insulated cable.
