RU2286080C2 - Device for inspection of density of tissue at endoscope testing - Google Patents

Abstract

FIELD: medical equipment.

SUBSTANCE: device for inspecting density of tissue at endoscope testing has endoscope provided with tissues' density detectors connected to computer system. Tissues' density detectors have to be pressure transducers made in form of elastic chambers filled with medium perceiving pressure, for example, with physiological solution. Chambers are mounted at edge of endoscope. Computer system is made for separate measurement of density of part of tissue by means of pressure transducers and for registration of pressure resistance in dynamic mode. Tissue can be easily inspected for uniformity and density.

EFFECT: widened capabilities of inspection.

Description

The present invention relates to medicine and medical technology, in particular to the practice and technique of endoscopy of hollow organs - the stomach, duodenum 12, etc., as well as other body cavities (pleural, abdominal, pelvic space, etc.).

Known methods and structures for the implementation of endoscopic examination, as hollow organs, and physiological, pathological and artificial cavities of other formations (tumors) in the body.

Famous laparoscopic endosurgical complex "Olympus" Japan (see the catalog of the company in 2004), used for operations on the abdominal organs.

In particular, recently, flexible multifunctional endoscopes containing an optical system of light-conducting fibers enclosed in a flexible frame with the ability to control the working part introduced into the cavity under examination, as well as with a working channel for supplying and evacuating liquid and glue, have become most widespread. , laser LED, manipulators, in particular for biopsy material collection and with the possibility of lighting (Duodenofibroscope, TJF-300 external d = 13.0 mm, channel d = 4.2 mm from Olympus I Onias, see. company's directory (see. 2004 Company of the catalog).

However, all of the above endoscopic systems do not allow the study of the underlying tissue located in the inspection area for its uniformity and density.

Known contact pressure sensor for the study of cavities, having a chamber filled with a gas medium, designed to determine the density of the mucous membrane of the nasal concha (RU 2240028, 20.11.2004). The sensor is connected to the means of fixation and data processing. However, its technical capabilities do not allow examination in deep body cavities.

An endoscopic system for measuring biophysical tissue parameters is also known, in which tissue density is measured during an intracavitary medical examination (US 6711429, 03/23/2004), in which the density of the underlying tissue is measured by a sensor at the endoscope end. However, the system does not allow the researcher to form an effect similar to the direct touch of the object being examined.

The aim of the invention was to expand the research capabilities of the underlying tissue in the inspection area for its uniformity and density with the creation of the effect of the researcher, similar to the direct touch of the inspected object.

This goal is achieved by the fact that in an apparatus for studying tissue density in an endoscopic examination containing an endoscope with tissue density sensors connected to a computer system, tissue density sensors are pressure sensors made in the form of elastic chambers filled with a pressure-sensing medium, for example, physiological saline, mounted on the endoscope end face, and the computer system is capable of separate fixation by each pressure sensor of the density of the underlying tissue site and register ation resistance to pressure in the dynamic mode.

In addition, in addition, pressure sensors can be installed on adjacent side surfaces of the endoscope.

The drawing shows a block diagram of a device.

The device consists of an endoscope 2 (drawing) with tissue density sensors 1 connected to a computer system 3, 4, which, in turn, can have a unit for fixing the resistance of the underlying tissue sections to obtain the “touch” effect recorded by the operator’s hand.

The design of the device, combined with the training of operators, allows you to expand the information for subsequent clinical use. The proposed device is relatively simple and designed with the possibility of further combination with various endoscopic devices.
