Skin flap blood circulation induction system and method for operation area

Technical Field

The invention relates to the technical field of medical tools, in particular to a skin flap blood circulation induction system and method for an operation area.

Background

The vascular crisis refers to the phenomena of blood flow obstruction caused by anastomotic spasm or embolism after surgical suture of small blood vessels, ischemia or extravasated blood of organs or tissues, and can be divided into arterial crisis and venous crisis, wherein vasospasm is usually observed in the early stage, and embolism is observed in the late stage. In clinic, the blood circulation condition of the skin flap needs to be observed in many occasions, for example, free skin flap transplantation and severed finger replantation are common surgical operations and have obvious effect on treating severed fingers, but the blood vessel crisis is also one of the most serious postoperative complications of free skin flap transplantation and severed finger replantation, the incidence rate is about 20%, and the accurate prediction of the blood vessel crisis is the key of successful operation. Therefore, it is necessary to accurately monitor the blood transport of the flap. At present, instruments or apparatuses specially used for observing or monitoring blood transportation appear in the market, although the exposure degree of an observation area of an operation area is reduced and the risk of infection is reduced, on one hand, the monitoring parameters are single, and the accuracy of blood transportation monitoring is low; on the other hand, focusing on "observation" rather than "prediction", when a blood circulation abnormality is observed, a situation such as a flow back disorder may have occurred, so that the optimum time for taking measures is missed. Therefore, the prior art cannot accurately sense blood circulation, cannot early warn artery crisis or unsmooth venous return in advance, and cannot prompt medical staff to intervene in time.

The basic scheme provided by the invention is as follows: an operative skin flap blood transport induction system comprising:

the image acquisition module is used for acquiring a monitoring image of a patient;

the time detection module is used for pressing the skin flap of the operation area to detect the blood filling time of the capillary vessel;

the volume detection module is used for monitoring the blood perfusion volume in the capillary;

the central processing module is used for identifying whether the expression of the patient is uncomfortable according to the monitoring image, calculating the average blood transport flow at the flap position according to the blood filling time and the blood perfusion volume when the expression of the patient is uncomfortable, predicting whether the blood vessel crisis occurs to the patient according to the average blood transport flow and the preset flow threshold value, and sending an alarm instruction to the alarm prompting module if the blood vessel crisis occurs;

Has the advantages that: if the skin flap in the operation area is abnormal, the blood flow disorder can be continued for a period of time, but the patient does not feel the blood flow disorder, and prediction can be performed at the moment to prevent the blood flow disorder from continuously deteriorating.

Further, the device also comprises a tension detection module used for detecting the skin tension of the skin flap in the operation area; the central processing module is further used for judging whether the swelling degree is normal according to the skin tension, calculating the average blood transport flow at the flap position according to the blood filling time and the blood perfusion amount if the swelling degree is abnormal, and predicting whether the arterial crisis or the venous crisis of the patient occurs according to the average blood transport flow and the size of a preset flow threshold.

Has the advantages that: similarly, if the swelling is not normal, the restriction will likely have persisted for some time, but the patient will not feel it, and the prediction will prevent the restriction from worsening.

Further, the central processing module is connected with a blood circulation display module and used for displaying the change process of skin color, skin tension, blood filling time and blood perfusion amount.

Has the advantages that: the change process of skin color, skin tension, blood filling time and blood perfusion amount can be displayed in real time through the display screen, so that medical personnel can visually check the change rule of related data and find out the bad condition of the skin flap in an operation area in time, and effective preventive measures are taken.
