Abstract

Usage: the invention relates to a laser “irrigip” and can be used when cutting tissue with a laser beam The essence of a surgical laser behind it with a longitudinal pass-through on one jaw and a protective screen on the other is set on the dissected area of the biological tissue, then using an additional jaw in the form of a slider mounted on a branch with a through groove and connected to the fiber carriage by rigid rods, move the carriage along the groove and scatter bioten. Positive effect of the chain is to increase the convenience The behavior of the operation - is achieved in that all the operator manipulation during dissection of biological tissue installation, compression, dissection, has the ability to be carried out using about one-toly hand yl 2

Description

The invention relates to a laser nr / rpil and can be used to dissect and fabric with a focussed laser beam.

A device is known that comprises two articulated intersecting intersecting arms with handles, a lock and a locking jaw, and one of the jaws of the jaws has a through longitudinal groove for transmitting laser radiation, and the other jaw is solid. The disadvantages of the device are as follows. In its implementation, preliminary guidance is required, which consists in laying in a double + sappeto -:, when a beam hits the moisture in this place, which makes it possible to detect a focal point. This focusing method does not provide accurate focusing of naaepi radiation to a through longitudinal groove, In addition, the beam may accidentally hit the unprotected TI AN All this reduces the quality of the operation and increases the time it takes

Closest to the claimed technical essence and accepted as a prototype, is a device for dissecting any tissue, described in the literature. A device with a security clamp, consisting of two joints jointly with ring handles, jaws, a cremallera and a lock A longitudinal through groove is made in one of the jaws. A groove is inserted into the groove. 0 Part of the optical fiber for supplying a laser laser containing a focusing lens or a system of pins. A disadvantage of the device is the inconvenience of operation, which is explained by the fact that Mr. psnuzh den spetopod advance along the groove with his free hand he Pleated 1geoB odim assistant. This leads to the consolidation of the quality of the operation.

The chain of the invention is intended to increase the convenience during the operation. The delivered circuit is achieved by

that, as in the prototype, the device contains two articulated jaws with ring handles, a rack, a lock and working jaws. One of the jaws has a longitudinal through groove and the output part of the laser fiber is placed. The output part is made in the form of a carriage and can move along the groove, Second the sponge is made in the form of a protective screen. In contrast to the prototype, the device contains + it an additional jaw in the form of a pop-up with an annular handle mounted on a jaw with a through longitudinal groove. The additional branch is connected to the fiber carriage by rigid rods.

As a result of using the proposed device, the surgeon can hold the trench with the same hand and simultaneously pass along it with a laser beam, that is, one hand is released, which makes the operation process for the surgeon more convenient, and therefore the operation itself is of a higher quality

In Fig. A, a device for dissecting tissue in a rectangular yordinate is shown; in Fig. 2, also an axonometry, where I are articulated jaws with ring handles, 2 are working jaws, 3 is a cremapier and a lock, 4 is a longitudinal through units, 5 — the first part of the laser fiber, 6 — the popawn of the additional branch, 7 — the annular handle of the additional branch, 8 — stiffer than the thrust.

An example of a specific implementation (Fig. 1,2). The total length of the device for dissecting tissues is 200 mm, the length of the sponges is 2-50 mm On one sponge 2 is a through. Groove 4 with a length of 43 mm At first, part of the optical fiber 5 is placed in the groove 4 and moves along it. A favorable part of the optical fiber 5 contains an optical lens allowing focusing radiation on tissue

The device is made of steel grade CT4x13.

The device operates as follows

Biotissue is placed with sponges 2 Jointed branches with annular handles 1 compress the biological tissue. The degree of clamping is regulated by pressing fingers and locked with a lock 3

The radiation is turned on, it is brought to the tissue through the advantageous part of the laser fiber 5 and the output part of the fiber 5 is moved along the groove 4 by the ring handle of the additional branch 7 on the slider 6

double-sided, rigid, two-spoke type 8 As a result, bloodless aseptic dissection of the biological tissue occurs. Laser radiation is generated by a tissue laser using copper vapor with a power of 20 W

Technical and economic efficiency is due to an increase in the quality of the operation, which will lead to a more rapid recovery of the patient, restoration of his working capacity and the absorption into the production process, and, consequently, a reduction in payments under the job certificate
