RU38566U1 - DEVICE FOR MONITORING THE URETROTOM MOTION TO THE SIDE OF THE PROXIMAL DEPARTMENT OF THE URETHRA IN THE INTERNAL OPTICAL URETROTOMY OR DEZOBLITERIA - Google Patents

Abstract

The proposal relates to medicine, namely to urology and can be used when performing internal optical urethrotomy or urethral deobliteration in connection with strictures. The device is made in the form of a bougie from a hollow tube equipped with a light source at the working end. The technical result of the use is to reduce the invasiveness, reduce the time of the operation, create better working conditions for the surgeon.

Description

The proposal relates to medicine, namely to urology and can be used to facilitate the implementation of internal optical urethrotomy or deobliteration of the urethra due to strictures and obliteration of the urethra.

Despite the tangible successes achieved recently, the problem of treating patients with strictures and obliteration of the urethra for many hospitals remains a difficult and largely unsolved problem.

When performing internal optical urethrotomy and urethral deobliteration, a metal curved bougie is usually used to determine the direction of movement of the urethrotome (Novikov NF, Alexandrov VP, Artemov VV “Endoscopic methods of treatment of urological patients”, St. Petersburg , 2002). This bougie is injected antegrade into the proximal urethra through a cystostomy fistula. The latter serves as a guide for the urologist. In this case, the direction of movement of the urethrotome is determined by the displacement of tissues in the affected area.

The disadvantage of this tool is the difficulty of accurately determining the direction of movement of the urethrotome by the surgeon. No other devices have been identified by the applicants to solve this problem. Bougu, to determine the direction of movement of the urethrotome, was adopted by us as a prototype.

Objectives: to facilitate visualization of the proximal urethra and, consequently, reduce tissue trauma and blood loss, reduce bedtime and rehabilitation of patients.

The technical essence of the proposal is that the bougie is made in the form of a tube equipped with a power source and, at the working end, a light source.

The device is further illustrated in figure 1, where:

1 - hollow tube, 2 - light source (bulb), 3 - transformer, 4 - electric wire.

The device is used as follows: Transformer 3 is connected to the mains. Through an electric wire 4, electricity is supplied to a light source. During the operation, the assistant antegrade through the epicystostomy fistula introduces the hollow tube 1 with the working end into the cavity of the bladder, and then through the neck of the bladder into the posterior urethra to the affected area, periodically turning off the light source on the urethrotome. Focusing on the light penetrating toward the scar tissue, the urologist dissects the latter with a “cold” urethrotome knife. The next step is the resection of the scar tissue and the Foley catheter.

The device, when used, allows for less tissue trauma and blood loss, reduction of hospital beds and rehabilitation periods, reduction of the number of intraoperative and postoperative complications, and allows patients with concomitant pathology to perform operations. side of other systems and organs, due to low invasiveness, as well as patients with relapses of the disease, previously repeatedly and unsuccessfully operated in an open way.

Claims (1)

A device for controlling the movement of the urethrotome toward the proximal urethra during internal optical urethrotomy or deobliterapy, containing a rigid curved bougie, characterized in that the bougie is made in the form of a hollow tube equipped with a power source and a light source at the working end.
