DEVICE FOR MEASURING blood circulation esophagus and stomach during the formation of an artificial esophagus during surgery

摘要

The invention relates to clinical thoracoabdominal surgery, in particular to methods and devices for determining the consistency of the seams ezofagogastroanastomoza (EGA) for hysterectomy esophagus. A problem in the design of devices for measuring blood supply to the esophagus and stomach tissues during the formation of the esophagus while the operation is the presence of interference caused by the oscillations thoracic patient card caused by the work of his cardiovascular and respiratory systems, as well as vibrations medical clip having a source and a radiation receiver located in the hands of a surgeon. A disadvantage of many devices is the lack of fixation of the distance between source and receiver of infrared radiation, since it is defined subjectively by the operator, and medical clip design does not allow the locking pin snaps to compounds jaws, ie before full compression of tissue and clamping of blood vessels of the esophagus and stomach, which leads to an increase in the measuring path of influence on the measurement object and, as a consequence, to increase measurement error.; The technical result, which aims at achieving a useful model - increase noise immunity and accuracy of determining the value in the study of blood flow pulsation due to the creation of a stable and adjustable distance between source and receiver of infrared radiation.; An apparatus for measuring the perfusion of the esophagus and the stomach tissue in the formation of an artificial esophagus during operation comprises a medical clamp 1 fitted source 2 and receiver 3, infrared radiation, fixed on the distal ends of the clip Branche, adjustable magnetic abutment secured between the proximal ends of branches with ring handles and consisting of two parts, one of which comprises a threaded axle 4 with the adjusting wheel 5 mounted at one end in the threaded hole near the annular handles audio jaws and the spherical magnet 6 fixed to the other end of this axis, while the other part is the stop lock, consisting of a magnetic metal cone collector 7, passes into a cylindrical bar 8 fixed coaxially a first abutment portion on the distal end of the second jaws. Thus, interference when moving medical clip recorded on the tissue of the esophagus or stomach wall, caused by fluctuations in the surgeon's hand, will be minimized if the condition of absence clamping receptacles investigated area esophagus and stomach, which will increase the efficiency of detection sections thereof with the maximum value of blood flow pulsations. 1 yl.
