Description

The utility model relates to medicine, and more specifically to proctological instruments used in operations on the rectum - excision of hemorrhoids, polyps, anal fissures, fistulas.

Known proctoscope containing a housing with a handle, an eyepiece, a lighting system, a pneumosupercharger, a tube and an obturator (1).

The disadvantage of this proctoscope is the invasiveness of the study.

Known proctoscope containing a housing, an eyepiece, a lighting system, a pneumosupercharger, a transition sleeve with a rotary tube and with a L-shaped slot (2).

The disadvantage of this device is the increased complexity of the design.

A device for examining the rectum containing a tube with a longitudinal slot, a backlight system and a movable rod (3) is known.

The disadvantage of this device is the possibility of damage to the surrounding soft tissues during surgery.

A known channel extender for a patient’s body containing articulated jaws with working jaws and a jaw dilution mechanism (4).

The disadvantage of this extender is the increased complexity and inconvenience of use.

A device for internal research and surgical treatment of diseases of the rectum, containing a rod, a hollow cylindrical tube with a slot and a lighting system located on the wall of the tube (5).

The disadvantage of this device is the possibility of tissue injury.

Also known is a channel extender for a patient’s body, comprising a handle, two branches with working jaws pivotally mounted on the handle, and a branch breeding mechanism (6).

The disadvantage of this extender is the inconvenience of use and the possibility of injury to tissues during surgical interventions on the rectum.

The purpose of creating a utility model is to increase ease of use and reduce the morbidity of surgical intervention.

This goal is achieved by the fact that the working jaws are made in the form of removable U-shaped staples from elastic wire material equipped with clamps, and the device can be made of biologically and chemically inert 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 Assembly; figure 2 - shows a device placed in the anal canal.

The proposed device contains a handle 1 and jaws 2 and 3, mounted with their proximal sections on the hinges 4 and 5 of the handle 1.

The handle 1 is equipped with a branch breeding mechanism containing a screw 6 with a wing 7; a sleeve 8 is pivotally mounted on the distal end of the screw 6, interacting with the proximal ends 9 and 10 of branches 2 and 3. At the distal ends of branches 2 and 3, working jaws are made in the form U-shaped staples 11 and 12 of elastic wire material, equipped with clamps 13 and 14.

The device can be made of an alloy of metals or of a biologically and chemically inert polymeric material, which allows multiple antiseptic treatment.

The device is equipped with a set of removable working jaws of various sizes, designed for patients with various anthropometric characteristics and various ages (children, women, men).

The device is used as follows.

Working jaws 11 and 12 in a closed state are introduced into the anal canal. By turning the wing 7 of the branching mechanism, the branch 6 screw is screwed into the handle 1, while the sleeve 8 acts on the proximal ends 9 and 10 of the branch 2 and 3, spreads their distal ends with working jaws made in the form of U-shaped staples 11 and 12 of elastic wire material, thereby expanding the anal canal of the patient. Make the necessary manipulations to excise hemorrhoids, polyps, etc.

Working jaws are firmly held in the anal canal without additional fixation by the hands of the surgeon or his assistant.

The implementation of the working jaws of elastic wire material increases the overview of the surgical field, allows you to visually control the entire course of the surgical intervention, which, in turn, reduces the complexity, improves quality and accuracy, reduces the time of surgery, eliminates the possibility of excessive tissue injury.

The proposed device is simple in design, reliable and efficient to use.

The device is advisable to use in proctology departments of medical institutions.
