Definitions
- the invention relates to a medical instrument for preparing tissue in the human or animal body, with an elongated shaft, with two relatively movable jaw parts at the distal end of the shaft, which interact in a cutting and / or gripping manner, with at least one of the jaw parts acting as a radio frequency current Electrode is formed.
- preparation is understood to mean cutting tissue and / or grasping tissue in order to separate and remove tissue in the body or to set it aside.
- Such an instrument is preferably used in minimally invasive surgery, in which, in contrast to conventional open surgery, the instrument is guided through a small incision from the outside into the operation area, the operation being carried out under endoscopic control.
- the jaw parts or at least one of the jaw parts are additionally subjected to monopolar high-frequency current in order to reduce the cutting effect due to the thermal effect of the high-frequency current in the To increase tissue, and on the other hand to bring about a coagulation of the tissue at the point of separation through the development of heat, in order to reduce or even stop the bleeding which occurs when the tissue is severed.
- a bipolar coagulation instrument two at the distal end has spaced-apart pairs of jaw parts, each pair of which is designed as an electrode to which high-frequency current can be applied.
- the two pairs of jaw parts are spaced apart from one another and can therefore be operated as a bipolar electrode arrangement.
- a cutting tool in the form of a scalpel is arranged between the jaw part pairs and can optionally be moved back and forth.
- this instrument With this instrument, a vessel can be clamped and coagulated between the two pairs of jaws and then pushed forward of the cutting tool are cut.
- this instrument is less suitable to be used primarily as a dissecting instrument for cutting tissue, but the main function of this instrument is bipolar coagulation.
- the cutting action by means of the displaceable scalpel arranged between the coagulation electrodes is purely mechanical, i.e. without support from high frequency current. Furthermore, these cutting devices are primarily suitable only for severing vessels, but not for making longer cuts and also not for grasping.
- an instrument of the type mentioned at the outset is therefore functional, since with such an instrument the focus is on severing tissue .
- the invention is therefore based on the object of further developing an instrument of the type mentioned in such a way that even larger tissue parts and thus larger tissue bridges containing larger vessels can be severed with this instrument without the risk of excessive bleeding.
- this object is achieved with respect to the instrument mentioned at the outset in that a further electrode which can be acted upon by high-frequency current is provided, which can optionally be displaced from a retracted proximal position into a distal position adjacent to the jaw parts, in which it cooperates with the at least one as Electrode-formed jaw part forms the second pole of an electrode arrangement for bipolar coagulation of tissue.
- an instrument is provided according to the invention with which it is possible to prepare tissue by cutting and / or gripping using a monopolar operated instrument and possibly to coagulate very small vessels in a monopolar manner as is conventional.
- this tissue bridge can be gripped by advancing the further electrode into the distal position adjacent to the jaw parts between the jaw parts and the further electrode.
- the at least one jaw part designed as an electrode and the further electrode can then be acted upon with bipolar high-frequency current, so that the tissue located therebetween can be bipolarly coagulated.
- the jaw parts form one electrode pole and the further electrode the second electrode pole.
- the jaw parts can be further prepared, either with a purely mechanical or monopolar current.
- the invention thus provides a monopolar instrument for preparing tissue in combination with an optionally switchable bipolar Ren coagulation device ready, which achieves the considerable advantage that no instrument change is required for preparation and for bipolar coagulation and larger tissue parts can be prepared quickly and safely while avoiding bleeding.
- the jaw parts are curved out of the longitudinal axis of the shaft and the further electrode is arranged on the concave side of the jaw parts.
- This measure has the advantage that the bipolar tissue to be coagulated between the jaw parts and the further electrode can be gripped and held securely when the further electrode is pushed into its distal position.
- the curved configuration of the jaw parts acts as a catch hook and abutment when the further electrode is advanced against lateral deflection of the tissue.
- the further electrode is flat and has approximately the same width dimension as the two jaw parts.
- the advantage here is that larger tissue sections can be coagulated with one coagulation process.
- the jaws can bipolar coagulate the Tissue can be opened or closed, the effective electrode area of the jaw parts being increased in the open position of the jaw parts.
- the further electrode forms at least one of the jaw parts as a catching space for gripping tissue.
- This configuration has the advantage that even thicker tissue and even thicker vessels can be gripped between the further electrode and the jaw parts.
- the further electrode is recessed into its retracted position in the shaft.
- the advantage here is that the further electrode in its retracted position does not hinder the preparation of tissue to be carried out primarily with the instrument by means of the two jaw parts and is only pushed out of the shaft when necessary.
- the further electrode is chamfered at the distal end on the side facing the jaw parts.
- the advantage here is that when the further electrode is pushed forward it is avoided that the tissue to be gripped between the jaw parts and the further electrode is displaced by the further electrode and then cannot be coagulated between the further electrode and the jaw parts.
- the aforementioned curved configuration of the jaw parts is particularly advantageous in this context, since the concave side of the jaw parts acts like a hook and abutment when the further electrode is pushed forward, so that the tissue cannot move sideways when the further electrode is pushed forward.
- the further electrode is at least partially elastic and describes a path curve during the advance, which initially runs approximately in the longitudinal direction of the shaft with or without a component slightly facing away from the jaw parts and towards the distal position with the component directed towards the jaw parts .
- the electrode describes a curved trajectory during advancement by means of a suitable guide or a prestress imparted to the electrode during advancement, as a result of which the tissue to be coagulated is gripped more easily during advancement and in the maximum advanced distal position between the Mouth parts and the other electrode can be securely held or pinched.
- a run-up slope is arranged on the shaft, onto which a run-up slope formed on the further electrode runs when the electrode is advanced, as a result of which the electrode is pressed against the jaw parts in the distal position. This advantageously ensures that the tissue can be held between the maximally advanced further electrode and the jaw parts with a higher clamping force.
- a run-on slope is arranged on the shaft, so that when the further electrode is advanced, it is initially spread apart from the jaw parts and resiliently springs against the jaw parts in the distal position.
- the further electrode can initially be pushed away from the jaw parts during advancement, which in turn allows even larger tissue parts to be securely gripped. Due to the elastic springing of the further electrode in its distal position towards the two jaw parts, the enclosed tissue is then automatically held securely between the jaw parts and the further electrode for bipolar coagulation.
- a handle is arranged at the proximal end of the instrument, which has two handle parts for actuating the jaw parts and a further handle part for actuating the further electrode, the handle parts forming a handle arrangement that can be operated with one hand.
- This measure has the advantage that the actuation of the jaw parts on the one hand and the optional actuation of the further electrode, namely the advancement and retraction of the further electrode, can be carried out particularly conveniently and above all in one-hand operation. This is how it is handled of the instrument according to the invention improves and enables fatigue-free working with the instrument.
- the further handle part is connected to the further electrode via a lever arrangement such that the further electrode is pushed from its proximal to its distal position by pulling the further handle part.
- This configuration of the further grip part further improves the user-friendliness of the instrument because actuation of the further grip part to advance the further electrode by pulling enables better force metering and thus safe working with the instrument.
- the further electrode is prestressed into its proximal position, into which it automatically returns after the further grip part has been released.
- This measure further improves the user-friendliness of the instrument according to the invention.
- the further electrode is connected to the further grip part via an actuating element which is axially movable in the shaft, the actuating element being further connected to a high-frequency current feed via a sliding contact.
- the axially movable actuating element results in a particularly advantageous transmission of force between the further handle part and the further electrode on the one hand and on the other hand an advantageously constant transmission due to the sliding contact. structurally simple and safe loading of the further electrode by current conduction through the movable actuating element.
- the sliding contact allows current to be passed through to the further electrode only when the electrode is advanced into the distal position or almost into the distal position.
- This configuration advantageously improves the operational safety of the instrument according to the invention.
- the actuating element can be removed from the further grip part, preferably connected by latching.
- the advantage here is that the instrument can be easily dismantled with respect to the coagulation device provided according to the invention.
- the jaw parts are removably connected to the handle parts via an actuating element which is axially movable in the shaft.
- This configuration of the connection of the jaw parts to the shaft creates a configuration which is advantageously easy to operate for connecting and detaching the jaw parts from the shaft.
- the instrument can be dismantled into the assemblies from the jaw parts with the actuating element connected to them, the further electrode with the further actuating element, the handle and the shaft.
- the instrument can be dismantled into the four above-mentioned assemblies, the instrument according to the invention can be cleaned particularly thoroughly and thus meets the highest hygiene requirements.

It can also be provided that the further electrode 112 forms such a coagulation electrode arrangement only with one of the jaw parts 116, 118.
- the further electrode 112 is partially elastic, specifically at a proximal section 120.
- the further electrode 112 is rigid and solid, and has approximately the shape of a knife, but without a sharp cutting edge.
- a turn bevel 122 is in turn formed on the shaft 114, which is designed to be slotted in the longitudinal direction of the shaft 114, the further electrode 112 being guided longitudinally in the slot (not shown) during advancement.
- the further electrode 112 When the further electrode 112 is pushed forward, it runs over the run-up slope 122 and is initially spread apart by the jaw parts 116, 118, as shown in broken lines in FIG. 10, as a result of which a larger catching space between the jaw parts 116, 118 and the further electrode 112 is achieved.
- the further electrode 112 has an indentation 124 in the proximal region. As soon as the indentation 124 reaches the run-up slope 122 when the further electrode 112 is advanced, the further electrode 112 resiliently springs against the jaw parts 116, 118. The further electrode 112 accordingly describes a path curve during the advance, which curve initially points away from the jaw parts 116, 118 Component and in the last section of the movement path has a component directed towards the jaw parts 116, 118.
