Abstract

For removal of urinary calculi from the ureter of the human body it has hitherto always been necessary to carry out an operation. The concrement gripper comprising a cystoscope with a mandrel which is connected to a U-shaped spring and a gripper can be introduced into the human ureter without problems due to its flexibility, so that an operation is unnecessary. In the process of removal of calculi the concrement gripper is opened by pressure on the U-shaped spring and can embrace the calculus. By release of the spring the calculus is retained and can be pulled out of the ureter together with the concrement gripper. In order to ensure individual applicability the concrement gripper can be produced with a variety of catheter shaft diameters and catheter shaft lengths.

Bezeichnung: Konkrementgreifer (zum Entfernen von Harnleitersteinen aus dem menschlichen Körper) Diese Erfindung betrifft ein Instrument, das auf dem Gebiet der Urologle in der Lage ist, tief-mittel und hochsitzende Harnleitersteine aus dem menschlichen Körper zu entfernen.Description: Concrete gripper (for removing ureter stones from the human body) This invention relates to an instrument that is based on the The area of the Urologle is capable of deep-medium and high-seated ureteral stones to remove from the human body.

Da man mit dem bisher üblichen Instrument, der sog.Since you can use the previously common instrument, the so-called.

Schlinge, es nicht wagen konnte, mittel und hochsitzende, eventuell spitze Harnleitersteine über die großen Gefäße zu ziehen, die den Harnleiter ca. lo cm über der Blase kreuzen, war bisher immer ein operativer Eingriff nötig.Noose, couldn't dare, medium and high-seated, possibly pulling sharp ureter stones over the large vessels that make up the ureter approx. Crossing lo cm above the bladder, surgery has always been necessary up to now.

Vorgang zur Steinentfernung durch den Konkrementgreifer: Der Konkrementgreifer wird durch ein Cystoskop in den Harnleiter bis zu dem zu entfernenden Stein eingeschoben.Process for stone removal by the concrement gripper: the concrement gripper is inserted through a cystoscope into the ureter up to the stone to be removed.

Hiernach wird der urologische Röntgen tisch um ca. 45 Grad gekippt und der Konkrementgreifer durch Druck auf die U-Feder geöffnet. Dadurch wird der Harnleiter leicht gespreizt und der Stein fällt praktisch von allein in den Greifer. Durch Loslassen der U-Feder wird der Stein umfaßt und festgehalten. Der Konkrementgreifer kann nun mit dem Stein aus dem Harnleiter herausgezogen werden.The urological X-ray table is then tilted by approx. 45 degrees and the concrement gripper is opened by pressing the U-spring. This will make the The ureter is slightly spread and the stone practically falls into the gripper by itself. By letting go of the U-spring the stone is grasped and held. The concrement grab can now be pulled out of the ureter with the stone.

Diese Erfindung beruht auf Beobachtungen von Funktion und Arbeitsweise chirurgischer und urologischer Instrumente und löst bisherige Instrumente ab. Zudem wird ein bisher erforderlicher operativer Eingriff grds. vermieden.This invention is based on observations of function and operation surgical and urological instruments and replaces previous instruments. In addition a previously required surgical intervention is basically avoided.
