The device according to claim 1, characterized in that it is made of a biologically and chemically inert material.

Description

The utility model relates to the field of medicine, and specific to the field of marking of excised areas, mainly areas of excised perforated duodenal ulcers.

Based on morphological and morphometric studies of the edges of perforated ulcers and tissues around the perforation, it was found that the most pronounced acute inflammatory changes are observed in the areas immediately adjacent to the ulcer defect and remain at a distance of at least 5 mm from it. At a distance of 10 mm from the perforation edge and further, moderately pronounced fibroplastic and minimal inflammatory processes are observed, extending to more distant sections of the duodenal wall. Thus, the chronic perforated duodenal ulcer should be excised, departing at least 10 mm from the edge of the perforation. This will almost completely remove the focus of chronic inflammation and autoimmune aggression. In addition, scarring processes are already sufficiently reduced at this level, which ensures good healing of the organ wall after surgery.

A known method for determining the section of the abdominal wall depending on its condition (1, 2).

The disadvantage of this method is the increased invasiveness.

Known measuring device containing a flexible measuring element with a linear scale (3).

The disadvantage of this device is the complexity of use for marking excised areas.

A measuring device is known comprising articulated jaws having pointed ends and a connecting rod with a measuring scale (4).

The disadvantage of this device is the inability to use it to mark the excised area of the ulcer.

Known measuring device containing two racks, a guide with a scale and a slider (5).

The disadvantage of this device is the inability to use it to mark the area of the excised surface of the ulcer.

A known method for determining the excised area, in which the excision border is determined within the limits of healthy tissues on the "eye" (6).

The disadvantage of this method is that it does not allow to clearly determine the boundary of excision of the ulcer and, as a result, increased invasiveness.

A known measuring tool containing articulated legs and a bar with a scale (7).

The disadvantage of this device is the complexity of determining the boundary of excision of an ulcer.

Also known is a measuring device containing articulated jaws, a jaw position lock and a measuring scale (8).

The disadvantage of this device is the inability to accurately mark the boundary of the excision area of perforated duodenal ulcers.

The purpose of creating a utility model is to enable accurate marking of the excision area of a perforated duodenal ulcer.

This goal is achieved by the fact that the proximal ends of the branches are rigidly interconnected, the distal ends of the branches are located at a distance of 10 mm from each other, with the installation needle stop placed at the distal end of one of the branches, and a marking element made on the distal end of the other branch in the form of a ball coated with a solution of diamond greens. Moreover, the device is made of a biologically and chemically inert material.

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, which shows the proposed device.

A device for marking the excision area of a perforated duodenal ulcer contains a persistent jaw 1 and a marking jaw 2, which are rigidly connected by their proximal ends. At the distal end 3 of the jaw 1 there is an installation needle stop 4, and at the distal end 5 of the jaw 2 there is a marking element 6, made in the form of a ball, covered before marking with a solution of diamond green.

To mark the excision area of a perforated duodenal ulcer, the device is used as follows.

The marking element 6, located on the jaw 2, is covered with a solution of brilliant green (for example, by dipping). The installation needle stop 4 is placed on the edge of the perforated hole of the ulcer, the marking element 6 is marked, repeating these manipulations 4-6 times from all sides of the perforated hole. Excision is carried out at the marked marking points. Excision is performed at a distance of 10 mm from the perforation edge, i.e. in the most optimal place. The implementation of the device from a biologically and chemically inert material allows for its multiple antiseptic processing and use.

Using the proposed device allows with minimal effort to accurately mark the area of excision of perforated duodenal ulcer in the most optimal place. The device is simple in design and reliable in operation.

The device is possible and appropriate to use in the surgical units of medical institutions.
