A device for introducing drainage, consisting of a metal tube, inside which there is a drain, characterized in that the tube has a piston with a rod, a metric thread is applied to the rod, the distal end of the tube has a threaded channel through which the piston rod with thread is moved, the proximal end part the tube on the outer surface has a screw adapter with a rounded thread profile, the tube has a handle.

Description

The utility model relates to surgery, namely, devices for conducting drainage operations and can be used for the prevention and treatment of purulent-inflammatory diseases and their complications.

A device for introducing drainage is known, comprising a tube and a stylet with a handle, characterized in that the tube in the middle part is curved and has a hole in the curved section for the passage of the stylet, located along the axis of the rectilinear section (RF Patent No. 2004104806/20 A61M 27 / 00 February 2, 2004).

The disadvantages of this device are the poor adaptation of the device to the edges of the wound with the introduction of drainage, insufficient retention of the device with the introduction of drainage with the risk of loss of the latter, the difficulty of introducing and removing the device from the wound, the inability to accurately position the drainage in the wound.

A device for introducing drainage is known, consisting of a curved, sharpened rod from one end with three cutting faces, conical bevels are made on the distal end of the rod in the cylindrical part, on which the drainage tube is worn, the maximum diameter of the distal part of the tool exactly corresponds to the outer diameter of the drainage tube ( RF patent No. 92007519/14 A61M 25/08 from 07/27/1995).

The disadvantages of this device are the poor adaptation of the device to the edges of the wound with the introduction of drainage, insufficient retention of the device with the introduction of drainage with the risk of loss of the latter, the difficulty of introducing and removing the device from the wound, the inability to accurately position the drainage in the wound.

A device for introducing drainage is known consisting of a metal tube, inside which a drainage is placed with a metal insert to push it out (RF Patent No. 2006126175/22 A61B 17/00 of 07/19/2006).

The disadvantages of this device are the poor adaptation of the device to the edges of the wound with the introduction of drainage, insufficient retention of the device with the introduction of drainage with the risk of loss of the latter, the difficulty of introducing and removing the device from the wound, the inability to accurately position the drainage in the wound.

This device is taken as a prototype.

The purpose of creating a utility model is to create a device for introducing drainage, providing increased adaptation of the device to the edges of the wound when introducing drainage, retention of the device when introducing drainage, facilitating the introduction and removal of the device from the wound, the ability to accurately position the drainage in the wound.

This goal is achieved by the fact that the tube has a piston with a rod, a metric thread is applied to the rod, the distal end of the tube has a threaded channel along which the piston rod with a thread moves, the proximal end of the tube on the outer surface has a screw adapter with a rounded thread profile, the tube has a crank.

Comparison of the proposed device with others known in the field of medicine showed its compliance with the criteria of a utility model.

The technical result of the utility model is to increase the adaptation of the device to the edges of the wound when the drainage is introduced, to ensure the retention of the device when the drainage is introduced, to facilitate the insertion and removal of the device from the wound, and to enable accurate positioning of the drainage in the wound.

A useful device is illustrated in graphic material. Figure 1, in section, shows a device for introducing drainage, consisting of a metal tube (1), inside which a drain (2) is placed, a tube having a piston (3) with a rod, a metric thread (4) is applied to the rod, the distal end part of the tube (5) has a threaded channel (6) along which the piston rod with thread (4) moves, the proximal end part of the tube (7) on the outer surface has a screw adapter (8) with a rounded thread profile, the tube has a handle (9).

The device is used as follows.

In the treatment of purulent-inflammatory diseases and their complications, a device for introducing drainage is installed in the wound channel by rotating the tube handle, drainage is introduced into the wound by rotation of the piston rod, and a drainage device is introduced by reverse rotation of the tube handle. Dialysis of the wound. Apply an aseptic dressing.

Achievements of the technical result are confirmed by clinical examples of the use of the proposed device in the clinic of maxillofacial surgery of Samara State Medical University.

Clinical example 1. Patient S., 51 years old. Diagnosis - Odontogenic phlegmon of the submandibular region on the left. The patient underwent surgery-opening phlegmon. Under intravenous anesthesia, an incision was made in the submandibular region on the left parallel to the marginal branch of the facial nerve, 2 cm from the edge of the lower jaw. The skin, subcutaneous fat, the superficial fascia of the neck, and subcutaneous muscle were dissected. Taken to the ligature and crossed the facial vein. Stupidly passed into the submandibular region. Received pus in a volume of 12 ml. Hemostasis. The wound is washed with antiseptic solutions. A device for introducing drainage from a metal tube is installed in the wound channel by rotating the handle of the tube, drainage is introduced into the wound by rotation of the piston rod, drainage is introduced by the reverse rotation of the handle of the tube. The wound was dialyzed with antiseptic solutions. An aseptic dressing is applied. The formation of granulations on the 9th day.

Clinical example 2. Patient S., 32 years old. Diagnosis - Odontogenic phlegmon of the submandibular region on the right. The patient underwent surgery-opening phlegmon. Under intravenous anesthesia, an incision was made in the submandibular region to the right parallel to the marginal branch of the facial nerve, 2 cm from the edge of the lower jaw. The skin, subcutaneous fat, the superficial fascia of the neck, and subcutaneous muscle were dissected. Taken to the ligature and crossed the facial vein. Stupidly passed into the submandibular region. Received pus in a volume of 9 ml. Hemostasis. The wound is washed with antiseptic solutions. A device for introducing drainage from a metal tube is installed in the wound channel by rotating the handle of the tube, drainage is introduced into the wound by rotation of the piston rod, drainage is introduced by the reverse rotation of the handle of the tube. The wound was dialyzed with antiseptic solutions. An aseptic dressing is applied. The formation of granulations on the 9th day.

The proposed model can be used in dental practice in the departments of maxillofacial surgery, general surgery, traumatology, gynecology, urology, cardiac surgery and several other areas.
