SU1228837A1 - Arrangement for extracting foreign bodies from tubular hollow organs - Google Patents

Description

one.

The invention relates to medical instruments, in particular for the intraoperative extraction of stones from the common gall and liver pro-, currents, and can be used both when removing foreign bodies from the trachea, bronchi, esophagus through the natural, openings, and from hollow organs through external fistulas. .

The purpose of the invention is to increase the reliability of capture of foreign bodies.

FIG. 1 shows a device for the extraction of foreign bodies, with a general view; in fig. 2 shows section A-A in FIG. 1, in FIG. 3 is a diagram of a device captured by a stone in a tubular organ.

The device for removing foreign bodies comprises an outer tube 1 and an inner tube 2 placed therein with the possibility of longitudinal movement. On the outer tube 1 a tip 3 is fixed, having a recess 4 and through guide channels 5 for elastic threads 6 forming a gripping frame. Channels 5 are made at an angle to the longitudinal axis 7 of the device. The device has a tensioning mechanism for 8 threads 6.

The operation of the device is as follows.

position, t, ze. with the filaments of the carcass pulled in, they are introduced into the cavity and propelled up to the narrowest part of the duct. Next, the external tube 1 is moved towards itself, while the elongation is. These filaments, melted inside the duct, form a fascinating multi-cell frame. Simultaneously with the movement of the outer tube 1, a rotational movement is reported, which facilitates the penetration of the stone into the frame and securely fixing it in the recess 4, the manipulator is pulled into the outer loop frame 1 until several stones or stones are fixed in the frame 1 after which the device is removed from the duct. The manipulation is repeated until the stones are completely free from the duct.

The device has an additional gripping effect due to the possibility of increasing the number of framing yarns to ten and more than 25, if necessary, which can be enhanced by a cruciform (or lobe-shaped) arrangement of loops and recess on the working surface of the tip. In addition, the device does not injure the internal
