A medical instrument for diagnostic, therapeutic, or surgical measures in a cavity in the body of a patient may include a proximal region, which is provided and designed for arrangement outside the body, a distal region, which is provided and designed for arrangement inside a cavity in the body, a supply structure for delivering a fluid to the cavity, wherein the supply structure reaches from a first coupling in the proximal region of the medical instrument to an outlet in the distal region, and a discharge structure for discharging a fluid from the cavity, wherein the discharge structure reaches from an inlet in the distal region of the medical instrument to a second coupling in the proximal region of the medical instrument. The flow resistance of the supply structure is greater than the flow resistance of the discharge structure.

The disclosure relates to a medical instrument for minimally invasive tissue ablation by means of an HF electrode, with a hollow shaft, wherein the HF electrode is electrically insulated from the hollow shaft, is arranged at a distal end of the latter and, in order to ablate tissue, protrudes axially beyond the hollow shaft at least in part. The angle orientation of the HF electrode relative to the hollow shaft is adjustable in a controlled manner to a working position in which the HF electrode, protrudes radially beyond an outer circumference of the hollow shaft in order to ablate tissue. In the working position, by means of suitable adjustment of the shaft and of the HF electrode, a position can always be found in which the distal end of the HF electrode sufficiently reaches or touches tissue portions that are to be ablated in the region of the bladder neck.

An electrode arrangement according to the invention for a bipolar resectoscope () comprises an elongate electrode carrier (), an active electrode disposed at a distal end of the electrode carrier () and a neutral electrode, wherein a distal end section of the electrode carrier () is embodied as an electrode body () through which a supply line () of the active electrode is guided and wherein the neutral electrode is formed by the electrode body () or a portion of the electrode body (). The invention also relates to a resectoscope ().

An access system for endoscopic operations includes of a trocar, a cover that is fittable on the trocar and at least one spreading element having a retaining portion and an effector portion, wherein the access system has, between the trocar and the cover in the fitted state, a receiving region for the retaining portion of the at least one spreading element. Furthermore, the access system can include an extraction bag which is expanded by the effector portion of the at least one spreading element.

A medical coagulation instrument having a shaft as well as at least one electrode tip that extends beyond the distal end of the shaft. To create a coagulation instrument whose electrodes are of simple structure and ensure an atraumatic and safe handling, at least one electrode tip should be widened or be configured as widening in the distal direction.

A coupling mechanism for mechanically connecting a first structural part and a second structural part of a medical instrument includes a first component and a second component, which are designed to be connected to each other by a bayonet connection that permits a rotation of the second component relative to the first component about a rotation axis, and a detent mechanism for alternately locking the second component in several alternative and mutually different predetermined angle positions relative to the first component.

A retractor with at least two spreader arms that can be displaced relative to one another and can be blocked by a blocking device and on their end sections are provided with blades that can be displaced in their gripping ranges. The blades are of unit construction and are inserted so that they can slide in linear guides forms from spreader arms in such a manner that can be fixed in a range of freely chosen positions each corresponding to various griping ranges by means of a releasable fixing device.

A medical instrument with an elongate shaft which, at a distal end, carries a spatula, and, in a proximal end area, has a shaft head on which a laterally protruding handle is arranged. The shaft is rotatable relative to the handle about a rotation axis parallel to a longitudinal axis of the shaft.

A handle for a medical instrument having a handle housing and a connection adapter for hose and/or tube connections, which can be inserted into the handle housing. The connection adapter can be inserted fluid-tight into a corresponding support recess of the handle housing by at least one connection support and such that a surrounding ring groove for inserting a sealing element is positioned on the at least one connection support. It is proposed that at least two surrounding ring grooves, mounted one behind the other, should be configured on the connection support in the axial direction of the at least one connection support, such that the connection support has a constant outer diameter in the area of the at least two ring grooves and such that a sealing element, is positioned at least in the first ring groove, looking from the free end of the connection support.

Clamping device

The invention relates to a spreadable medical instrument for endoscopic interventions having a base body, a handle positioned on the base body, and at least two spatula blades that are connected with the handle and can be displaced between a closed starting position and at least one working position parallel and/or at an angle to one another by means of an adjustment device, in such a way that the adjustment mechanism is positioned on the handle so that it is possible simultaneously to grip the handle and activate the adjustment mechanism with the same hand. To create a spreadable medical instrument that has the widest possible range of applications and is easy and safe to operate, it is proposed with the invention that the adjustment mechanism is configured as a continuous, adjustable screw-in mechanism.
