Description

Endoscopic clamp for determining the viability of organs and

The utility model relates to medical equipment and can be used in surgery to clamp and simultaneously study viable hollow organs.

A device for stopping bleeding from the hepatoduodenal ligament according to the certificate for a utility model of the Russian Federation No. 0006692, class. 6 A61B, taken as a prototype, containing containing jaws connected to the handle using a rod mounted in the hollow cylinder.

The disadvantage of this device is that this device performs only one function - this is a clamp, a narrow specialization of this device.

The aim of the creation of this invention is to expand the functionality of this device.

This goal is achieved by the fact that an endoscopic clamp for determining the viability of organs and tissues, containing jaws connected to the handle using a rod installed in the hollow cylinder, where the optocoupler is mounted on the branches in the form of an LED on one of the branches and a photodiode on the other connected to current source, transducer and recording device.

This invention will expand the functionality of the device, with which you can clamp and perform studies of viable hollow organs.

The invention is illustrated in the drawing, where in FIG. 1 shows a general view of an endoscopic clip without an electronic part; FIG. 2 - block diagram of the electronic part.

tissues

The endoscopic clamp for determining the viability of organs and tissues contains jaws 1 and 2 connected to the handle 3 by means of a rod 4 installed in the hollow cylinder 5 and the handle 6. Both handles 3 and 6 are spring-loaded with each other 7. An optocouple is installed on the branches 1 and 2 in the form of an LED 8 located on the branch 2 and a photodiode 9 on the branch 1. The light diode 8 and the photodiode 9 are connected via a cable 10 to a switch 11, a current source 12, a converter and 13 and a recording device 14,

An endoscopic clamp for determining the viability of organs and tissues works as follows:

When releasing the handles 3 and 6, the handle 3 presses on the rod 4, and that in turn releases the branches 1 and 2, which are moved apart. The endoscopic clamp, with jaws 1 and 2, is applied to the studied area of the organ and the handles 3 and 6 are released, the handles 3 and 6 are brought together by the action of the spring 7, while the handle 3 pulls the rod 4, which in turn pulls the jaws 1 and 2 into the inside of the cylinder 5 closing the last. Branches 1 and 2 clamp the test organ. The clamp holds the organ in a certain position. If you want to conduct a study of this organ, you need to turn on the electronic part of the device with switch I. When you turn on the electronic part of the device, LED 8 supplies infrared radiation to the organ under investigation, which, passing through the organ, changes depending on the state of the object being studied and the changed radiation receives photodiode 9 and transmits a signal cable 10 to the Converter 13, which converts the signal into a readable form and provides the recording device 14. The recording device 14 displays the received information tion about the state of the investigated organ.
