Method for evaluating blood supply state of parathyroid gland in operation

Abstract

The invention discloses a method for evaluating the blood supply state of parathyroid glands in an operation, which comprises the following steps of: in a thyroid operation, identifying and confirming parathyroid glands, fixing the parathyroid glands by using tweezers, taking out a needle head to puncture the envelop of the parathyroid glands, puncturing the parathyroid glands into the glands, pulling out the needle head, and observing the bleeding condition on a needle eye on the parathyroid glands. The blood supply state of the parathyroid gland is evaluated according to the grading of the bleeding condition, and whether the parathyroid gland is suitable for in-situ retention or autotransplantation is determined. The blood supply condition is determined by directly puncturing the parathyroid gland, the method is safe, accurate and reliable, the operation is simple and convenient, time is saved, meanwhile, special equipment is not needed, and the method can be widely developed and applied clinically; the syringe needle with the size can ensure that the blood supply state of the parathyroid gland can be accurately evaluated, massive hemorrhage of the parathyroid gland cannot be caused, and the syringe needle is safe and efficient.

Description

technical field [0001] The invention relates to the medical field, in particular to a method for evaluating the blood supply state of the parathyroid glands during surgery. Background technique [0002] The parathyroid gland is located near the thyroid gland and is very small, round or oval in shape. The human body generally has two pairs of parathyroid glands; the parathyroid gland is one of the endocrine glands and is a flat oval body, about 3-8 mm long , 2-5 mm wide, 0.5-2 mm thick, located behind the lateral lobe of the thyroid gland, sometimes hidden in the thyroid parenchyma, generally divided into upper and lower pairs, each weighing about 35-50 mg, the surface of the parathyroid glands is covered with thin Layer of connective tissue capsule, the connective tissue of the capsule carries blood vessels, lymphatic vessels and nerves into the glands to become trabeculae, dividing the glands into incomplete lobules. The parathyroid glands generally have upper and lower pai...

Problems solved by technology

[0003] Hypoparathyroidism is the most common complication after thyroidectomy, especially permanent hypoparathyroidism not only increases the burden of patients taking calcium tablets for a long time, but also affects the function of eyes and kidneys, increasing the risk of malignant tumors and death Although autologous parathyroid gland transplantation will increase the incidence of temporary hypoparathyroidism after surgery; but for parathyroid glands that are preserved in situ but have no blood supply during surgery, autologous transplantation will reduce the incidence of permanent hypoparathyroidism in patients Therefore, how to accurately judge the blood supply status of parathyroid glands in thyroid surgery to determine whether the parathyroid glands need autologous transplantation is of great significance

[0004] At present, there are no good clinical equipment and technical methods for evaluating the blood supply status of parathyroid glands in thyroid surgery. Fluorescence imaging can indirectly reflect the blood supply status of the parathyroid glands, but the fluorescence imaging endoscope system used in this method is expensive (about 3 million RMB) and cannot be routinely used in clinical practice, and those who are allergic to iodine Patients cannot inject indocyanine green intravenously, and the system is time-consuming and complicated to use
