RU64499U1 - DEVICE FOR PERFORMING THORACOCENTESIS - Google Patents

Abstract

Usage: medicine, breast surgery. Essence: the device consists of a sleeve in which the stylet is located; in the center of the stylet there is a longitudinal channel for holding a guide made of a plastic tube, closed at the distal end and open at the proximal end, with a side opening and a stopper cylinder worn on the guide and fixed to the guide above and below the side hole.

EFFECT: shortening the treatment time for acute limited empyema of pleura and lung abscess, reducing mortality and disability, ensuring safety and reducing the level of trauma during thoracentesis. 2 ill.

Description

The utility model relates to medicine, namely to breast surgery, and can be used to perform thoracocentesis with limited pleural empyema and lung abscess.

A trocar is known for performing thoracocentesis with the aim of draining the pleural empyema and lung abscess cavity, as well as performing thoracoscopy and abscessoscopy consisting of a stylet and a sleeve (P. Kesler, in the book by I. Littman Surgical Surgery. - Budapest. - Publishing House of the Hungarian Academy of Sciences. - 1982. - pp. 77-78).

The disadvantage of this trocar is the difficulty of its accurate conduct in the direction of small cavities bounded by empyema of pleura and lung abscesses. Due to the inaccurate introduction of the trocar, it may not enter the cavity of the limited empyema of the pleura or lung abscess and injure the lung tissue.

The utility model is aimed at solving the problem of highly accurate and safe thoracocentesis with small sizes of the pleural empyema cavity or the lung abscess cavity.

EFFECT: shortening the treatment time for acute limited empyema of pleura and lung abscess, reducing mortality and disability, ensuring safety and reducing the level of trauma during thoracentesis.

A useful model is shown in the drawing, Fig. 1 shows a sectional view of a tool, Fig. 2 shows a general view of a tool, during which a limited pleural empyema is introduced into a cavity.

The device consists of a sleeve 1, in which a stylet 2 is located, in the center of which there is a longitudinal channel 3, for guiding 4, which is made of a plastic tube with an outer diameter of 1 mm, closed at the distal end 5 and having a side hole 6, for

the injection of fluid through the proximal open end 7 into the restrictor cylinder 8, made of a piece of elastic rubber tube with an inner diameter of 1 mm, worn on the guide 4 and fixed to the guide 4 above and below the side hole 6.

The trocar works as follows. Under the control of fluoroscopy, at the site of the closest approximation of the suppuration shadow to the chest wall, pleural puncture is made with a needle with an inner diameter of 1.2 mm. After receiving pus, the guide 4 is inserted into the needle, the needle is removed, the trocar is assembled on the guide 4. Up to 2 ml of furatsillin is introduced into the proximal open end of the tube 7, which inflates the restriction balloon 8, after which the proximal open end of the tube 7 is closed with a clamp. The swollen balloon-restrictor 8 does not allow the guide 4 to migrate from the empyema cavity, the patient is transported from the X-ray room to the operating room and the trocar is introduced into the cavity of the empyema with constant pulling of the guiding string 4 outward until the stylet 2 and the balloon-stop 8 come in contact. With continued pulling of the string - guides 4 outside spend stylet 2 another 1 cm forward. At the same time, the restriction cylinder insures the walls of the empyema cavity from injury with stylet 2 of the trocar. If stylet 2 moves in the direction of the wall of the empyema cavity, the trocar must first damage the restrictor 8 to damage it. If the restrictor 8 is damaged, the string leaves the stylet 2 of the trocar, which signals the danger of lung injury. After the trocar enters the cavity of the delimited empyema of the pleura or abscess of the lung, guide 4 and stylet 2 are removed from the sleeve of the trocar 1 through which drainage or thoracoscopy is performed.

The effectiveness of the proposed tool is confirmed by good clinical results in 29 patients.

Thus, the proposed trocar allows accurate thoracocentesis with delimited pleural empyema and lung abscess and avoid the risk of lung tissue injury.

Claims (1)

A device for performing thoracocentesis, consisting of a sleeve in which the stylet is located, characterized in that in the center of the stylet there is a longitudinal channel for conducting a guide made of a plastic tube closed at the distal end and open at the proximal end, with a side opening and a restrictor balloon worn on the closed end of the guide and fixed to the guide above and below the side hole.
