Device and method for examination of a body cavity
First Claim
1. A device (1) for carrying out an examination of a uterus (20), comprising:
- a holder (2) having a tube (3) mounted thereon;
a catheter (5) slidably disposed within said tube (3), and defining an outflow opening (16);
a first operating knob (9), mounted on said holder, operatively connected to said catheter for slidably moving said catheter with respect to said tube (3);
a supply of sterile fluid to be supplied to the uterus (20) via said outflow opening (16) of the catheter (5);
a sealing element (4) mounted on said tube (3) to seal the uterus against leakage of the sterile fluid from said uterus,the catheter movable slidably with respect to the tube to thereby change a spacing between the sealing element and the outflow opening;
a plunger (6) slidably disposed within said catheter, said plunger (6) having a widened portion (15); and
a second operating knob (12), mounted on said holder (2), operatively connected to said plunger (6) for reciprocably moving said plunger relative to the catheter,said widened portion (15) of said plunger being positionable to be spaced distally of said outflow opening (16) to permit the sterile fluid to be supplied through the outflow opening to the uterus, said widened portion (15) of said plunger (6) being movable proximally of said outflow opening so that said plunger (6) functions with said catheter (5) to cause the widened portion moving proximally to create a vacuum at said outflow opening (16) to permit a tissue sample from within the uterus (20) to enter said outflow opening (16) for removal from the uterus (20).

Abstract
The invention relates to a device for carrying out an examination of a wall of a body cavity, in particular a uterus, which device comprises a catheter, supply means for supplying a sterile fluid to the body cavity via an outflow opening of the catheter, a sealing element for sealing the body cavity against leakage of the sterile fluid from the body cavity. The device furthermore comprises gripping means, operating means for operating the gripping means from a position outside the body cavity and transmission means for transmitting operating actions performed at the operating means to the gripping means, said transmission means extending through a further catheter via the sealing element, wherein said further catheter forms the catheter. The invention further relates to a method for examining a body cavity, using such a device.
