The invention relates to medical equipment, namely, equipment for endoscopic surgical operations, and can be used when aspirating fluids from the abdominal cavity during laparoscopic surgery.

A device for aspirating fluid from the abdominal cavity during laparoscopic operations (company "Karl Storz", model N 26331020 Hamou Endormat, 1989. The device provides automatic maintenance of a constant pressure and volume of gas in the abdominal cavity: reducing a gas pressure below a predetermined value, an automatic additional his insufflated into the abdominal cavity. The known device, the set of essential features and dostasuvawe fluid always happens and aspiration of a significant amount of gas, supplied into the abdominal cavity. The disadvantage of this design is that insufflator usually does not submit the required quantity of gas. When suction decreases the volume and pressure of the gas in the cavity, in result narrows the zone of visibility, which leads to the delay of the operation. These shortcomings are significant in situations that require rapid removal of the liquid under the condition of constant good overview of the area of operation (for example, when bleeding).

The objective of the invention is the development of devices which maintain a constant volume and pressure of gas in the abdominal cavity during intense sucking.

This object is achieved in that the device for aspirating fluid from the abdominal cavity during laparoscopic operations, consisting of insufflator, liquid receiver, vacuum pump, pipe system and trocars, characterized in that the fluid container and a vacuum pump through a system of tubes and trocars form with the abdominal cavity closed loop.

The invention is illustrated in the drawing.

The proposed device for aspirating fluid from the abdominal cavity during laparoscopic operatiom the fluid container 2 and the vacuum pump 3, together with a system of tubes 4 filter 5 and the trocar 6 form with the abdominal cavity 7 closed loop.

The device operates as follows. Pump 3 creates a vacuum, removed from the abdominal cavity 7, the liquid remains at the bottom of the receiver 2, and captured with liquid gas passing through the system of tubes 4 filter 5, is returned into the abdominal cavity 7 through the trocar 6. Thus maintain a constant volume and pressure of gas in the abdominal cavity, while the visible area of operation remains constant.

FIELD: medicine.

SUBSTANCE: method involves conducting bougie through the liver. Flexible tube is attached to its end and set in bile ducts. Flexible radio-opaque conductor is introduced through the flexible tube. The tube is removed. Draining tube is introduced along the conductor from porta hepatis to its diaphragmatic surface into the ducts to be drained.

EFFECT: reduced risk of traumatic complications.

FIELD: medicine.

SUBSTANCE: method involves puncturing pyogenic abscess cavity under ultrasonic control with draining tube left therein. Laparoscope connected to monitor unit is introduced into abscess cavity. One of introduced drains is set in upper point of the cavity and the other one in lower point. The abscess cavity is filled with ozonized solution to 2/3 of its volume and bubbled with ozone-oxygen mixture during 2-3 min changing the solution until it becomes transparent. The emptied cavity walls are treated from distance of 3-4 cm with laminar airflow heated to 38-40°C under pressure of 1-1.5 atm during 2-3 min. Next to it, the cavity walls are irradiated from distance of 2-3 cm with non-coherent red light during 2-3 min per each area.

EFFECT: improved safety conditions and healing quality.

FIELD: medical engineering.

SUBSTANCE: device has suction tube having lateral openings and irrigation tube. The irrigation tube is connected to jet-action atomizer. The atomizer is hollow collapsible cylinder with holes. Ultrasonic radiator having conductor to ultrasonic frequency oscillator is available in the cylinder. The radiator and conductor enable one to introduce ultrasonic oscillations into antiseptic solution.

EFFECT: enhanced effectiveness of treatment.

SUBSTANCE: method involves puncturing pyogenic cavity with trocar having blunt obturator via skin incision made outside of abscess boundary having length equal to arthroscope diameter. Then, arthroscope is introduced and the cavity is filled with physiologic saline. Pyogenic cavity revision is carried out under arthroscope control, irrigation cannula is set, constant water medium is created. Arthroscopic mill on shaver handle is introduced via another skin incision. Non-viable tissues are removed with stage-by-stage hemostasis using endocoagulator. The cavity is healed. Perforated draining tube is set under arthroscope control. Tube ends are brought out through pierces outside of the cavity and sutured to skin. Active suction of wound exudates is carried out using closed vacuum drain system in postoperative period. The drainage is removed when cleaning the wound from wound microflora and single sutures are placed.

EFFECT: enhanced effectiveness of treatment.

SUBSTANCE: the present innovation deals with treating patients in case of destructive forms of pancreatitis. One should lance a gastro-colic ligament, mobilize splenic and hepatic angles of large intestine, tighten a middle colic artery, descend mesenteric root cross-sectionally against a colon, dissect parietal peritoneum along the upper and lower edges of pancreas to withdraw it into abdominal cavity, remove necrotized tissues. Then one should apply a rubber balloon with drainage tubes along its upper and lower edges into omental cavity: one balloon's end should be withdrawn through median wound, another one - through contra-aperture being 5 cm below a costal arch along median axillary line. The method suggested enables to form adequate access to patient's pancreas.

EFFECT: higher efficiency of drainage.

SUBSTANCE: device has liquid-permeable porous lining that is to be placed on or in a wound, flexible plastic film having a set of holes distributed over its surface, liquid-impermeable film napkin and connection means. The porous lining has foamed polymer material having interconnecting cells. The plastic film makes contact with porous lining surface and is between wound surface and the lining when used. The film napkin is placed above the porous lining and is sticky along its perimeter to provide sealing in skin area surrounding the wound. The connection means passes through the film napkin and communicates to porous lining via liquid flow for making connection to negative pressure source for stimulating fluid flow discharged from the wound. Another embodiment has removable wound bandage usable in particular for treating large wounds requiring draining fluids. It has the first porous lining, the second porous lining, elastomer envelope, film napkin and tubular connection means. The first liquid-permeable porous lining contacts the wound and has foamed lining having foamed material based on polymer built of interconnecting cells and isolated transverse holes. The elastomer envelope has the first and the second sheets of elastomer film soldered along their periphery and enveloping said foamed lining. Each of the first and the second elastomer film sheets has spaced-apart holes. The holes in the second sheet are justified with said spaced-apart holes in the first sheet. The second liquid-permeable porous lining is to be placed under the first porous lining. It has foamed polymer material having interconnecting cells. The liquid-impermeable film napkin is placed above the second porous lining. The first porous lining is placed above the wound. The film napkin is sticky along its perimeter to glue the napkin to skin area surrounding the wound. The tubular connection means passes through said film napkin and communicates to porous lining via liquid flow for making connection to negative pressure source for stimulating fluid flow discharged from the wound. The third embodiment has the first elastomer film sheet having spaced-apart holes deviated from spaced-apart holes in the foamed lining. The second elastomer film sheet has spaced-apart holes adjusted to the spaced-apart holes in the foamed lining.
