Description

The utility model relates to the field of medicine, and more specifically to medical equipment, namely, devices designed to treat a wound surface in open surgical operations.

A known clamp (patent RU No. 2330624, A61B 17/28, 08/10/2008) containing two branches that are curved, connected by a hinge axis, have finger rings, handles and working parts in the form of clamping jaws. A longitudinal through groove is made on the clamping jaw of one of the jaws. Needle tabs are located on the clamping jaw of the other jaw. The needle protrusions have the ability to enter the groove of the jaw of the first jaw when the clamp is closed. The sponges are made with an elastic coating on the work surface. EFFECT: more reliable retention of a tissue layer during excision).

The disadvantage is the inconvenience of use in small wounds.

Known surgical instrument consisting of a working body with handles, housing, traction and springs. The spring is made of compression-return and connected at one end to a fixed handle and the other end through an axis to a movable handle. The second axis of the movable handle is the connection with the thrust of the working body. As a result, the disadvantages of the known tools are completely eliminated, since the spring provides only the necessary compression force of the working parts (parts) of the tool during clamping, grabbing or other surgical operations and the tool returns to its original position after removing the compressive force, (patent RU No. 2178992, А61В 17 / 00, 02/10/2002).

The disadvantage of this device is the unreliability of the fixation of abrasive material.

Known surgical instrument for tissue fixation. On interconnected branches there are working parts in the form of a transverse plate and an arc, which contains from 2 to 10 locking needles in length from 2 to 10 mm. The needles are located at an equal distance from each other, oriented to the transverse plate and mounted on the transverse part of the arc, made in the form of a U-shaped limiter of the surgical field. The U-shaped limiter has a distance between parallel parts exceeding by 0.2–4 mm the length of the transverse plate, which provides a sufficiently large area of a rectangular surgical field, and also contributes to reliable fixation of tissues, including under conditions of their deformation, underdevelopment, shortening, or tight infiltration with an anesthetic solution (patent RU No. 2107470, A61B 17/122, 03/27/1998).

The disadvantage of this device is the inability to securely fix the abrasive material.

Known surgical tool for holding and fixing tissues, which contains connected ends of the spring-loaded branches with a stopper and with working jaws located at an angle to the longitudinal axis of the branch. The working jaws have internal spikes and parallel radial surfaces in the form of guides of the cutting tool on the sides opposite to the branches. The working jaws are located transverse to the longitudinal axis and have parallel radius surfaces in the form of recesses made on the longitudinal axis of the jaw. The chord of the recesses is 1 / 8-2 / 3 of the length of the working jaws. The inner spikes have cross sections in the form of circles, or ovals, or polygons. On the surface adjacent to the working jaws of one of the branches there is a scale (patent RU No. 2218884 A61B 17/30, 20/20/2003).

The disadvantage of this device is the unreliability of the fixation of abrasive material.

Known surgical instrument, including two curved handles that are connected by a lock and equipped with a rack. Handles contain rings at one end and sponges at the other. One of the sponges on the back surface has a thrust plate for moving the second sponge above it. The plate is located on the convex surface of the sponge. A protrusion is made on the free edge of the plate to prevent the movable jaw from leaving the plate with optimal separation of the jaws. Sponges have cuts on working surfaces (patent RU No. 2193359, АВВ 17/16, 11/27/2002).

The disadvantage of this device is the excessive deformation of the abrasive material.

The technical result of the utility model is to increase the efficiency of surgical intervention due to reliable fixation of the working element at the end of the device, a full and reliable cleaning.

The technical result achieved is achieved by the fact that the surgical tampon holder is a casing consisting of two intersecting parts interconnected by a hinge located in the lower part of the casing. On the upper ends of both parts of the body are working cavities, on the inner surfaces of which there are teeth along the perimeter for better fixation of the bilateral sponge. In the middle of both upper parts of the casing, grooves are made in which a spring is used to create elastic traction, and a through threaded hole is made in the upper parts of the casing, in which the fixation bolt is located. To prevent over-opening of the two upper parts of the housing under the action of a spring, the device is equipped with limiters located in the hinge area.

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

The utility model is illustrated by graphic material, where in FIG. 1 shows an assembly model of the device, side view, in the working position; in FIG. 2 shows an initial side view of the tampon holder in an open state; in FIG. 3 shows the initial view of the tampon holder, a top view; in FIG. 4 shows a double-sided sponge.

The surgical tampon holder is a housing 1, consisting of two intersecting parts interconnected by a hinge 2 located in the lower part of the housing 1. In the middle of both upper parts of the housing 1 there are recesses 4 in which a spring 3 is located, which serves to create elastic traction in the open position. To prevent over-opening of the two upper parts of the housing 1 under the action of elastic traction - the spring 3, there are limiters 5 located in the lower parts of the housing 1. In the upper parts of the housing 1 there is a through threaded hole 6, in which the bolt-lock 7 is located, and on them at the ends are working cavities 8, on the inner surfaces of which along the perimeter there are teeth 9 for better fixation of the bilateral sponge 10.

A surgical tampon holder for treating a wound surface works as follows (Fig. 1). Pre-produce necrectomy of the wound, blunt and acute way. Then, for better processing and stimulation of the reparative process, a surgical tampon holder is used. The locking bolt 7 is rotated counterclockwise until the device opens. The bilateral sponge 10 is fixed in the working cavities 8 of the surgical tampon holder at the border of the transition of the soft part to the hard one. Holding onto the upper parts of the housing 1, bring them together, translating it into working position. The locking bolt 7 is rotated clockwise until it stops, for reliable fixation of the double-sided jaw 10 in the working cavities 8 of the device 1.

Using the proposed device reduces the complexity and improves ease of use, provides reliable fixation of the double-sided sponge, full and reliable cleaning, freedom of manipulation within the surgical field. Reliability and completeness of cleaning improves the working conditions of the surgeon, which, in turn, improves the quality and accelerates the course of surgery.

A device for the treatment of wound surfaces will be widely used in the surgical units of medical institutions.
