SU762869A1 - Device for making anastomoses - Google Patents

Description

The invention relates to medicine and relates to the design of the device, which can be used to impose lateral and terminal anastomoses, for example, between hollow organs.

A device for applying anastomoses is known, comprising a housing with a stop part carrying a matrix for bending the staples, a carriage with a staple magazine, a pusher and a knife, and a carriage drive [ί] located in the U body.

The device provides flashing of fabrics with a double-row chess-like seam, but it does not allow to form 15 side seams, which, after removing the device, are formed manually, which leads to an increase in the duration of the operation.

The aim of the invention is to reduce the time of the operation.

The goal is achieved by the fact that the matrix, bracket store, the working surface of the pusher and the knife have an i-shaped form. 25

anastomoses when working with the proposed device.

The device comprises a housing 1 with a stop part 2 and a carriage 3 located in the housing. The stop part 2 carries a matrix 4, in which holes 5 are made in two rows in a staggered manner for bending U-shaped brackets, and in the center there is a recess for a polyethylene shock absorber 6 of the knife blade 7. The case has a handle 8. 9 with cells 10 for U-framed brackets, arranged in two rows in a staggered manner and with a hole 11 in the central part, through which the knife 7 is attached, mounted on the pusher 12. The housing has an indicator window 13, which serves to determine the degree of compression of the stitched * tissues. The nut 14 provides movement of the carriage 3, and the handwheel 15 serves to move the pusher 12 with the knife 7. The matrix 3, the bracket store 9, the working surface of the pustelt 12 and the knife 7 are i-shaped.

The device works as follows.

In the organs between which it is necessary to create an anastomosis "side by side",

form holes through which the thrust and bracket parts of the device are inserted into the cavities (FIGS. 4 and 5) .. Rotate the nuts 14 to bring together the thrust and bracket parts of the device, while the degree of pressure of the organs' walls is determined using the pointer in the dicker box 13. During rotation the handwheel 15 of the organs' walls are stitched and at the same time a fistula is created between them. By rotating the handwheel 15 and the nuts 14 in the opposite direction, the stitched fabrics are released and the device is removed, after which the holes through which the stop and bracket parts of the device were inserted are sutured. When creating anastomoses "end to side" or "end to end"

(6 and 7) the end part of the hollow organ, which is scheduled to create end fistula, pre-sutured, leaving free only the angle through which either the thrust or the bracket part of the device is inserted. Then the stages of work are repeated in the specified sequence, Blago2

Since the matrix 3, the bracket store 9, the working surface of the pusher 12 and the knife 7 are u-shaped, the operation time is reduced, since after removing the device, the wound needs to be sutured manually only from the device insertion side.

Claims (1)
