(57) Abstract:

Usage: in experimental and clinical surgery. The essence of the invention: surgical stapling apparatus entered the movable limiter tissue, along with the adjustment of the distance between seams allow you to move the apparatus along shivamoga body. 5 Il.

The invention relates to medical engineering, in particular to the sewing apparatus used in experimental and clinical surgery.

Known surgical stapling apparatus. C. the USSR N 1442191, class. And 61 In 17/072, 1988), containing hard working part with holes to bend the brackets, bracket the working part with bracket store, mounted for movement in the direction of the store pusher and stopper fabric. A disadvantage of the known apparatus is the location of the hole to bend the brackets in one number that can not impose a two seam on the connected tissue, although the limiter tissues makes it a bit easier on them in the imposition of the device.

The closest to the invention is a surgical suturing apparatus [1], containing hard working part with rows of holes to bend the brackets oriented holes along the groove established by atom, and mounted for movement in the direction of the store pusher. This device allows not only to impose two seams on the joined fabric, but also through the bearing plate to change the distance between the seams.

However, the approach to the thrust plate in the known device is complicated, which is a significant drawback during the operation, in addition, the proposed device does not have a limiter fabric, which makes the imposition of the device.

The invention consists in that in the surgical suturing apparatus containing hard working part with rows of holes to bend the brackets, oriented along the holes of a flute that is installed in the groove of the bearing plate, bracket the working part with bracket store, made with the open side of the groove of the groove and mounted to move in the direction of the store pusher, entered into a movable limiter fabric, made in the form of related detachable lock with a hard thrust plate that is installed with the possibility of longitudinal displacement on the lateral surfaces of the bracket and resistant parts, when this split lock is made in the form of the stopper and the movable handle with symmetrically fixed transverse the couple notches, moreover, the pin is set to lock in a completed segment in the recesses of the grooves and with the ability to interact with opposite grooves of the retainer spring washer.

This design allows not only to flash lots of tissues, such as intestine, while two linear mechanical joints with visual control for changing the interval between the position at different distances from each other, but to facilitate the process of suturing.

In Fig. 1 shows a surgical stapling apparatus, a longitudinal section; Fig. 2 - section a-a in Fig. 1; Fig. 3 - section b-B in Fig. 1; Fig. 4 - section b-b of Fig. 3; Fig. 5 - section G-G in Fig. 3.

Surgical suturing apparatus includes hard working part 1 with a number of holes to bend the brackets, oriented along the holes of the groove 2, the thrust plate 3, bracket the working part 4 with bracket shop 5, made with the open side of the groove 2 groove 6, the pusher 7, the limiter tissue in the form associated with thrust thrust plate 3 8 and split lock, made in the form of the stopper 9, the movable handle 10, symmetrically fixed transverse pin 11, grooves 12, segmental grooves 13, grooves 14 and pridemage organ or tissue usively segment to move between the resistant part 1 and sobocki working part 4, fixed rod 8 on the thrust parts 1 and hard drive bracket 1 and 4 parts, providing free movement of the apparatus along shivamoga body.

The next step enter the thrust plate 3 in the groove 2 through the corresponding hole in the thrust 8 so that the transverse pin 11 fell into the segmental recess 13 through the slots 12 and bear against the clamping spring washer 15, further compressing the latter, turn the movable handle 10 clockwise until you feel the detent defined manual to stop free rotation of the movable handle 10. This transverse pin 11 gets into the grooves 14 and secures the retainer spring washer 15. After this rod 8 is moved along the bracket and hard parts on the distance required to increase the interval between imposed by the joints.

When this thrust plate 3 together with the thrust 8 is displayed outside of the thrust of the working part 1 in the direction of bracket store 5 and plunges usively tissue between the overlay sutures through the open side of the groove 2 groove 6 in the cavity.

The distance between imposed by the joints increases, and the size of the scheduled interval is controlled visually by the magnitude of the retraction of tissues is postupatelnoe moving thrust 8 at its opposite course (at the time of intussusception tissue).

After you install the required interval between the imposed linear bracket seams movable limiter tissue is fixed in position, bring the thrust bracket 1 and 2 of the machine to the optimum gap flashing, produce flashing of the General rules are then removed from the apparatus thrust plate 3 by opening the split lock, bred resistant part 1 and bracket the working parts, remove the device from deep wounds.

Remove a segment of a hollow organ after flashing excised after removal and removal of the device under visual control.

During the tests confirmed the ease and speed of adjustment of the correct position of the thrust surface of the working part of the thrust plate 3 relative to usively fabrics, simplicity and reliability ensure the correct orientation of the thrust plate 3 when installed in the groove 2 of the thrust part 1 at the moment of fixation due to the interlocking connection.

The effectiveness of the invention was confirmed by experiment on animals (dogs, n-12, a small weight of 4-6 kg) in the simulation of perforation of the rectal wall with subsequent resection of the damaged segment by applying the inventive apparatus, its prototype, the depth Porosimeter section of the intestine. Confirmed uptime split lock when using the apparatus in the depth of the wound, the speed and reliability of fixation at the full confidence of the surgeon the correct orientation of the working surface of the thrust plate 3 relative to usively tissues.

SURGICAL SUTURING APPARATUS containing hard working part with rows of holes to bend the brackets, oriented along the holes of a flute that is installed in the groove of the elastic plate bracket working with bracket store, made with the open side of the groove of the groove and mounted to move in the direction of the store pusher, characterized in that it introduced the movable limiter fabric, made in the form of related detachable lock with a hard thrust plate that is installed with the possibility of longitudinal displacement on the lateral surfaces of the bracket and resistant parts, when this split lock is made in the form of the stopper and the movable handle with symmetrically fixed transverse pin placed so that they can move in made in the stopper grooves and communicating with the slots segmental notches, and a pin installed to lock in made in the segment grooves grooves and opportunities
