Abstract

FIELD: medicine; anatomy.

SUBSTANCE: enter normal saline solution into fatty tissue of zone of preparation in amount of 10 ml on 20-30 mg of adeps, and then perform an ultrasonic cavitation of tissues apparatus Soft Lipomodel certificated in EEC №0068/ET1-PM/057-99. Allocate lymphonoduses, vessels and nerves in the uniform block. Then perform anatomic researches.

EFFECT: carrying out of anatomic research of vessels, nerves and lymph nodes in the uniform block and three-dimensional space, more detailed concrete definition of anatomic mutual relations between organs and tissues.

Description

The invention relates to medicine, namely to anatomy, and can be used for the anatomical preparation of the neurovascular bundle and lymphatic apparatus on fresh anatomical material.

The prototype is a method for the preparation of the neurovascular bundle and the lymphatic apparatus on fresh corpses, which is carried out, as a rule, using cutting tools - a scalpel, scissors, electrosurgical equipment, tweezers, clamps. Considering that the neurovascular formations and the lymphatic apparatus are localized in the cellular spaces, the goal of mobilization is to release the neurovascular bundle and lymphatic apparatus from the fiber. Known methods of mobilization (various options for anatomical preparation) do not allow the preservation of small vessels, ducts, capillaries, nodes. They are damaged, torn, intersect. Thus, it is not possible to maintain the microlevel of the anatomical relationship in a single unit. Thus, the informativity of the anatomical study, so important in modern conditions, is lost [Operative surgery and topographic anatomy: study. for medical schools./ Under. ed. Kovanova V.V., 4th ed., Ext., - M: Medicine, 2001. - 408 p.].

EFFECT: improved anatomical preparation of fresh anatomical material due to anatomical and morphological examination of blood vessels, nerves, lymph nodes and lymph vessels in a single block and three-dimensional space.

The specified technical result is achieved by the fact that in a method involving the isolation of blood vessels, nerves, lymph nodes and lymph vessels, followed by their anatomical examination, physiological saline is injected into the fatty tissue of the preparation zone in an amount of 10 ml per 20-30 mg of fat, then tissue ultrasound is cavitated and secrete lymph nodes, vessels and nerves in a single block.

We have developed a method for the anatomical preparation of the neurovascular bundle and lymphatic apparatus on fresh (not embalmed) corpses.

The proposed method is as follows. In the zone of the proposed anatomical preparation, physiological saline is injected at the rate of 10 ml per 20-30 mg of fat. After the injection, the preparation fields are processed by ultrasonic cavitation with the Soft Lipomodel device certified in EEC No. 0068 / ETI-DM / 057-99, as a result of which emulsification of fat occurs. Then, it is removed using napkins and an electric suction pump. All lymph nodes, lymph collectors, vessels and nerves are completely isolated in a single block. Ultrasonic cavitation destroys fat cells and tissue that envelop important anatomical structures. After evacuation of the fat emulsion, all anatomical structures and ultrastructures (small lymph nodes, lymphatic vessels, capillaries, nerves) become available for study. In the future, depending on the goal pursued, the drug can be further investigated.

In FIG. 1 shows a general view of the area of anatomical preparation before ultrasonic cavitation of fat; FIG. 2 - area of anatomical preparation with vessels, nerves, lymph nodes and lymph collectors in a single unit.

Previously, Soft Lipomodel was used for liposuction in plastic surgery.

The authors in the scientific, medical and patent literature did not find information about the popularity of ultrasonic cavitation of the preparation field for the anatomical preparation of the neurovascular bundle and lymphatic apparatus. Thus, the claimed invention meets the criterion of "novelty."

The authors found that the use of ultrasonic cavitation allows one to distinguish anatomical structures and ultrastructures, while maintaining the micro level of the anatomical relationship in a single unit. Thus, the claimed invention meets the criterion of "inventive step".

The proposed method of anatomical preparation of the neurovascular bundle, lymph nodes and lymph collectors does not require large material costs, it is easy to do in practice. Thus, the claimed invention meets the criterion of "industrial applicability".
