RU55264U1 - DEVICE FOR CONNECTING LASER RADIATION TO FABRICS THROUGH AN ENDOSCOPE - Google Patents

Abstract

The utility model relates to the field of laser surgery. The purpose of the utility model consciousness is to increase the reliability of fixing the device in the tube of the endoscope. The device contains an optical fiber, placed in a tube equipped with a handle, levers elastic fixing branches. The device is suitable for use in endolaryngotracheal and proctological laser surgery.

Description

The utility model relates to the field of medicine and is intended for use in laser surgery of the laryngotracheal region and the field of proctology.

Known obturator for an endoscope containing a rod with olive and a through hole.

The disadvantage of this obturator is the inconvenience of using for laser surgery.

A device for radiation therapy containing a catheter, a guide sleeve and a catheter rotation mechanism (2) is known.

The disadvantage of this device is the possibility of injury to surrounding tissues.

A device for supplying laser radiation, containing articulated jaws with working jaws (3).

The disadvantage of this device is the inability to use it to supply laser radiation through an endoscope.

It is also known a device for supplying laser radiation to tissues through an endoscope, containing an optical fiber placed in a tube equipped with a handle, articulated elastic branches and a lever pivotally connected to the handle (4).

The disadvantage of this device is the lack of reliability of fixation of the working end of the fiber in the endoscope.

The purpose of creating a utility model is to increase the reliability of fixing the working end of the fiber in the endoscope.

This goal is achieved by the fact that a fixed and movable spring-loaded coupling is connected to the tube connected by elastic branches, the movable coupling being connected to the lever by a flexible rod, and the three branches are made of resiliently flexible wire material.

Comparison of the proposed device with others known in the field of medicine showed its compliance with the criteria of a utility model.

The utility model is illustrated by graphic material. Figure 1 shows a General view of the proposed device, a view from the side, figure 2 - section aa in figure 1.

The proposed device for supplying laser radiation to tissues through an endoscope comprises a tube 1 with an optical fiber located in it, a handle 2, a lever 3 pivotally connected to the handle 2, and a fixed coupling 4 mounted on the tube 1 and a movable coupling 5. Couplings 4 and 5 are connected, at least three branches 6 made of resiliently flexible wire material. The movable sleeve 5 interacts with a spring 7 mounted on the tube 1, between the sleeve 5 and the stop 8. To the sleeve 5 is fixed at one end

flexible rod 9, secured by a second end to the lever 3. Flexible rod 9 passes through the channel 10 in the handle 2.

The proposed device is used when working with an endoscope equipped with a tube.

The proposed device is used as follows.

When the tube of the endoscope (for example, a sigmoidoscope) reaches the tumor, it is fixed. Then the device is introduced into the tube, while the fingers of the medical worker presses the lever 3 to the handle 2. A flexible rod 9 pulls the sleeve 5, which moves along the tube 1 and straightens the branches 6, which allows you to place the device in the tube of the sigmoidoscope. Then the fingers the medical worker unclenches. The movable sleeve 5 under the action of the spring 7 moves towards the working end of the tube 1. The jaws 6 are bent and come into contact with a relatively large surface with the inner surface of the sigmoidoscope tube, reliably fixing the working end of the tube 1. Laser irradiation is performed by a known method. The implementation of the jaw 6 of the elastic flexible wire material provides good binocular visibility of the surgical field. After laser radiation is performed, the lever 3 is pressed against the handle 2, thereby removing the contact of the branch 6 with the surface of the tube of the sigmoidoscope and removing the device from the tube.

The utility model can and should be used in endolaryngotracheal and proctological laser surgery. Its use allows you to reliably fix the working end of the tube in the tube of the sigmoidoscope, which, in turn, increases the effectiveness of the treatment process.
