Patent number: 11338079Abstract: 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.Type: GrantFiled: July 3, 2018Date of Patent: May 24, 2022Assignee: KARL STORZ SE & CO.

Patent number: 11266462Abstract: 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.Type: GrantFiled: August 30, 2018Date of Patent: March 8, 2022Assignee: KARL STORZ SE & CO.

Patent number: 10792117Abstract: A surgical instrument comprises a shaft, wherein a deflectable articulation section is formed at the shaft, a proximal handling portion at a proximal end of the shaft, a distal effector at a distal end of the shaft, and a deflection mechanism for controlling a bending state of the articulation section. The deflection mechanism comprises a first pull element for a deflection movement and a second pull element for a return movement. The first pull element and the second pull element are jointly pretensioned during the movement of the articulation section. An interface is provided where the instrument is demountable into a distal shaft assembly and a proximal handle piece, wherein the effector is controlled via an actuation mechanism that passes through the interface in a mounted state. The actuation mechanism comprises a push piece having a distal end that is coupled with the effector and a proximal end that is actuable by a pushing movement.Type: GrantFiled: January 18, 2018Date of Patent: October 6, 2020Assignee: KARL STORZ SE & CO.
