Problems solved by technology

[0004] However, intraoperative frozen pathological biopsy technology has the following disadvantages: 1. Frozen biopsy can only be used for in vitro identification, but cannot be used for identification of in vivo parathyroid glands. The judgment of in vivo parathyroid glands requires the subjective judgment of the surgeon , easy to misjudgment; second, the waiting time for intraoperative frozen biopsy of suspected parathyroid tissue is long, about 30 minutes or more, which increases the operation time and anesthesia time, thereby increasing surgical and anesthesia-related complications, It increases the working hours of the surgical staff and the operating cost of the patient, and reduces the efficiency of the operating room; the three isolated parathyroid glands are prone to ischemia due to waiting for pathological biopsy, which affects the functional recovery after re-transplanted back to the patient's neck muscles

Abstract

The invention particularly discloses a device and method for quickly recognizing a parathyroid gland in a thyroid surgery. The device comprises an impedance data acquisition unit for acquiring electrical impedance frequency spectrum data of a suspected parathyroid gland and an impedance data post-processing unit connected with the impedance data acquisition unit and used for conducting curve fitting on the measured electrical impedance frequency spectrum data, wherein the impedance data acquisition unit comprises an impedance acquisition probe in contact with the face of the suspected parathyroid gland, a data demodulation module connected with the impedance acquisition probe and an A/D conversion and processing module connected with the data demodulation module, and the impedance acquisition probe comprises a probe body and at least four testing electrodes evenly distributed on the probe body. The device and the method can remarkably shorten testing time, can also reduce tissue recognition misjudgment rate, accordingly decrease function injuries of the parathyroid gland, reduce the complication risk and also facilitate decrease of potential doctor-patient disputes.

Description

technical field [0001] The invention belongs to the technical field of bio-impedance technology identification of biological tissue, in particular to equipment and method for quickly identifying parathyroid tissue from thyroid tissue, parathyroid tissue, adipose tissue, lymphoid tissue and other tissues during thyroid tumor resection. Background technique [0002] Surgery plays an important role in the treatment of thyroid diseases, especially thyroid tumors. Due to the small size of parathyroid glands, large variations in number and location, and fragile blood supply, it is not uncommon to accidentally remove parathyroid glands or damage their blood supply during thyroid surgery, resulting in hypoparathyroidism. It has been reported in the literature that the incidence of temporary hypoparathyroidism in thyroid surgery is 6.9% to 46%, and that of patients with permanent hypoparathyroidism accounts for about 0.5% to 2%. It is related to factors such as the type of disease, ...
