Description

The utility model relates to surgical instruments used in particular for retroperitoneoscopy and can be used in surgical departments of medical institutions.

A known device for retroperitoneoscopy (patent No. 86085, A61B 1/07, 08/27/2009), containing a hollow body equipped with a handle with additional cylindrical hollow tubes located on its outer surface, forming channels for placing instruments, auxiliary devices and leading to the operating field washing liquid, while the working end of the hollow body, the channel of which is designed to accommodate a laparoscope with a video camera and fiber optics, is additionally equipped with a tempered glass eyepiece, one of the cylindrical tubes on the outer surface of the body is made with an inner diameter of 20 mm, providing the ability introduction through it into the retroperitoneal space of a drainage having a diameter of 20 mm, and the other two are made with the possibility of supplying through them, respectively, nitrous oxide into the retroperitoneal space and a sterile solution to the eyepiece glass, while on the surface of the cylindrical tube for the drainage is placed centimeter scale.

The disadvantages of the device are its technical complexity, which leads to the unreliability of the device, as well as the large size of the device, which creates additional difficulties for the surgeon during the installation of the device in the operating field and during the operation itself.

The technical result of the utility model is to increase the reliability of the device by simplifying the design, to facilitate the operating process by reducing the size of the device.

The specified technical result is achieved by the fact that the multiport device for retroperitoneoscopy is made in the form of a cylindrical body, 60 mm long, 50 mm in diameter, an inner hole with a diameter of 45 mm. In this case, an external thread is made on the distal part of the body, and on the proximal part of the body there is a 5 mm thick flange with a diameter of 70 mm, on which there are three holes (ports). One of them, located in the center of the flange, with a diameter of 25 mm and two others with a diameter of 15 mm, while on the inner side of the flange the holes (ports) are closed with non-return valves. The body is made of plastic or stainless steel.

An external thread located on the distal part of the body facilitates the penetration of the device into soft tissues and reduces their trauma, and the presence of three holes serving as ports allows the simultaneous use of up to three endoscopic instruments. The presence of check valves located on the inner side of the ports completely seals the operating field and allows the use of gas for endoscopic retroperitoneoscopy.

The multi-port device for retroperitoneoscopy is illustrated by graphic material, where in FIG. 1 shows the structure of the device. The body 1 is made of plastic or stainless metal, has a cylindrical shape with a length of 60 mm with an outer diameter of 50 mm, and an inner hole of 45 mm. The distal part of the body has an external thread 2. On the proximal part of the frame, there is a flange 3 5 mm thick with an outer diameter of 70 mm. Flange 3 is equipped with three internal holes (ports) 4, one of which is 25 mm in diameter and the other two are 15 mm, on the inner side of the flange the holes (ports) are closed with check valves 5.

The device works as follows. After access to the retroperitoneal space has been made, a multiport device in the form of a body 1 for retroperitoneoscopy is installed in the operating wound. Due to the external thread 2, the device is fixed in soft tissues. Through ports 4 located in flange 3, all the necessary endoscopic instrumentation is introduced into the retroperitoneal space, gas is injected into the abdominal cavity, while the pressure in the operation area is maintained due to check valves 5, after which retroperitoneoscopy is performed.

The device allows convenient and quick access to the operation area, retroperitoneoscopy in the gas-inflated operating area using the necessary endoscopic instrumentation. Clinical example.

Patient C, 36 years old, was admitted to the abdominal surgical department of the N.N. Seredavina 12/30/2020, with a diagnosis of pancreatic necrosis.

Infected postnecrotic pancreatic cyst. According to CT scan of the abdominal cavity, there is an acute fluid accumulation in the retroperitoneal space, spreading along the left flank, with free-lying sequesters. In the operating room on January 11, 2021, under general anesthesia, a retroperitoneoscopy was performed using a new multiport device for retroperitoneoscopy. The purulent cavity was sanitized. Intraoperatively, there were no complications during the removal of tissue sequesters. The operation went quickly. A drainage silicone tube with a diameter of 10 mm is installed. The device made it possible to carry out endoscopic retropeitoneoscopy quickly and conveniently.
