Abstract

FIELD: medical engineering. SUBSTANCE: device has pieces manufactured from dense flexible material. The pieces are connected with threads to form tetrahedral pyramid. Pyramid cavity is filled with medicinal solution. Pyramid montage enables the toxic exudate and detrite discharge conditions to be improved in all regions of the pancreas during operation. EFFECT: enhanced effectiveness of treatment. 2 dwg

Description

 The invention relates to medical equipment, namely to devices that improve the supply of low-frequency ultrasound to the objects of influence, as well as allowing free removal of pancreatic exudate and detritus from the omental bursa, pancreas and retroperitoneal fiber.

 A device is known for a single supply of ultrasound of low frequency energy to the peritoneum (Strukov A.I., Petrov V.I., Spiders V.S. Acute diffuse peritonitis. - M .: Medicine, 1987, p. 239), which is restrictive nozzle, which is worn on the waveguide.

 However, this device does not allow for multiple ultrasound effects on internal organs and tissues of the body without repeated operations, and also to remove large fragments of dead tissue for a long time after manipulation.

 A device for ultrasound examination of the body (SU, 304942, A 61 B 3/14, 06/04/71), containing a housing filled with a medicinal solution containing parts made of a material of dense elastic consistency (porous rubber). The device is mounted on the surface of the patient’s body. The known device, considered as a prototype, does not allow to further remove fragments of dead tissue after surgery.

 The purpose of the invention is the ability to repeatedly supply low-frequency ultrasonic energy to the pancreas and retroperitoneal fiber without repeated surgery, as well as improving the outflow of toxic exudate with detritus from all parts of the pancreas and surrounding retroperitoneal fiber. This is achieved by the fact that during the operation on the pancreas a device is installed in the form of a truncated tetrahedral pyramid, the top of which protrudes above the skin level of the anterior abdominal wall. The device consists of parts made of a material of dense elastic consistency with the possibility of filling them with a medicinal solution, while the parts are connected into a tetrahedral pyramid with threads.

 In FIG. 1 and 2 show a device for supplying low-frequency ultrasound to the pancreas.

 The device consists of separate symmetrically located parts made of a material of dense elastic consistency. Each part is in the form of a trapezoid with a base of 6 cm and a vertex of 2 cm 1 and 2, as well as 3 cm 3. The parts formed by them in the trapezoid position consist of four parts 1, two parts 2 and two parts 3 with a thickness of 0.5 cm and a height of 15 to 17 cm, depending on the development of fatty tissue. The corners and edges of the parts are rounded off under a radius of 0.5 cm. Along the perimeter of each part, departing from the edge of 0.3-0.5 cm, there are holes for holding the fastening thread.

 The specified device is used as follows.

 All parts are connected using a thread in a single unit before surgery and are stored sterile. During surgery, after a laparotomy, revision of the abdominal cavity and confirmation of the diagnosis of destructive pancreatitis, the omental bursa is opened by mobilization of the gastrointestinal ligament. They remove the effusion, mobilize the pancreas along the upper and lower edges, expose the retroperitoneal tissue, remove necrotic tissue in the gland and fiber, open the abscesses. Then, a pre-assembled device is installed above the pancreas and retroperitoneal fiber, it is filled with a medicinal solution, through which low-frequency ultrasonic energy is supplied. The spent solution is sucked off and the device is filled with antiseptics with tampons and drains. The wound is sutured in layers around the device. From the first day of the postoperative period, twice a day, sessions of low-frequency ultrasound exposure on the pancreas and retroperitoneal fiber are performed. The duration of each session is 3-5 minutes. The course of treatment is 6-10 sessions.

 This device allows you to act on the pancreas and retroperitoneal tissue in a state of necrobiosis and necrosis using the energy of low-frequency ultrasonic waves, which contributes to the rapid rejection of necrotic tissue. At the same time, drainage of the stuffing bag is carried out, which prevents the accumulation of pancreatic effusion with detritus and the development of severe purulent complications.

 After the required time has elapsed, the device is quickly and nontraumatically removed. To do this, the fastening thread crosses in one place, the thread is removed, after it the corresponding part is easily removed through the top of the pyramid.

 After a comparative analysis, using the proposed device in patients with acute destructive pancreatitis, the economic efficiency of the device is noted. Inpatient treatment of patients decreased by an average of 4.7 bed days.
