ABOUT

ABOUT

O1 oe yu>

The invention relates to medical instruments, in particular, for intraoperative extraction of stones from the common bile and hepatic ducts and can be used to extract foreign bodies from hollow organs through external fistulas, for example, gall and urinary bladders.

Tsil- invention - improving the efficiency of the device. 10

The drawing shows a device for extracting foreign bodies from tubular and hollow organs, General view.

The device consists ’of a tube 1, the distal end of which is sealed. A hole 2 is made on the lateral 15 surface of the distal end of the tube 1. The tube 1 is placed in the channel 3 of the side wall of the trap 4, which has two openings 5 and 6, one opposite to the other. Along the edge of the hole 5, channel 20 is connected to channel 3 of trap 4. In the tube 1, an elastic cable 8. is located with the possibility of longitudinal movement. It forms a movable loop 9. The loop 9 of cable 8 is located in channel 7 25 of trap 4. Both ends of the cable 8 are fixed by the mechanism 10 of the tension in the control ·. device 11. The control device 11 is presented in the form of a tube with the possibility of longitudinal movement 30 inside the tube 1.

The device operates as follows.

Through the microcholecystostomy opening, the device is in the initial position. 35

those. with a loop drawn inward, they enter the cavity of the gallbladder. Then the tube 1 is moved towards itself, while the elastic loop 9, expanding in the channel 7 of the trap 4, increases its hole 5 until its diameter 40 is equal to the inner diameter of the gallbladder. In this state, the tube 1 is advanced towards the neck of the gallbladder. The advancement of devices can be controlled “isual-45 but with the help of a choledochoscope. a bronchoscope, a cytoscope, introduced into the cavity of the trap 4 · through the hole 6. The hole δ of the trap 4 is not introduced into the cavity. By manipulating the hand, alternately retracting and extending the loop 9, if necessary, rotating the tube 1. they allow stones to enter the trap 4, after which the loop 9 is pulled into the tube 1 by moving the control device 11 towards itself. In this case, the elastic loop 9 sorbiruet channel 7 of the trap 4 and closes its hole 5.

Then, through the hole 6, a lithotripter device is introduced into trap 4, the calculi are destroyed, and their remains are actively “ingested” with a proton-draining device, which is alternately inserted with a lithium-blind curtain into the hole G of the trap 4. The procedure is repeated until the gallbladder cavity is completely released with g stones.

The device has an increased exciting effect due to the fact that the device for increasing and decreasing the hole of the trap is made in the form of a movable loop extending to the chepa; hole on the lateral surface of the distal end of the tube, and allows within the necessary limits to increase the hole in the pocket and close it completely. The device allows you to bring lithotriptor, flow-draining, as well as optical devices for visual control into the trap cavity due to the second hole in the trap of the device.

Claims (1)

Claim A device for extracting foreign bodies from tubular and hollow organs, containing a tubular body with a flexible -.yoga, forming an exciting loop with a trap fixed to it, characterized in that. in order to increase the efficiency of the device, a hole for passing a flexible loop is made on the side surface of the body, the plane of which is located at an angle of 90 ° to the longitudinal axis of the body, and the trap has an opening with a guide made diametrically opposite to the plane of the loop to accommodate optical devices.
