Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and specifically, to a one-stop pH measurement thyroid puncture biopsy needle. Background Technique

[0002] The thyroid gland is the largest endocrine gland in the human body, mainly secreting thyroxine and calcitonin, promoting material metabolism and energy metabolism, and promoting growth and development, with very important physiological functions; the incidence of thyroid cancer shows a high growth trend and has become one of the malignant tumors with a rapidly increasing incidence. Epidemiological studies have found that if high-resolution ultrasound is used, thyroid nodules can be found in 19 - 67% of randomly selected people; nodules can be tumorous or non-tumorous, and tumors can be benign or malignant, among which malignant tumors mainly include thyroid cancer, including four pathological types: papillary carcinoma, follicular carcinoma, medullary carcinoma, and undifferentiated carcinoma.

[0003] Thyroid puncture biopsy is mainly for thyroid nodules. Generally, a syringe with a puncture needle is used to aspirate the components of the thyroid nodule site, and then these components are sent to the corresponding department for analysis and evaluation to determine the nature of the thyroid nodule. In the prior art, the detection range of the puncture biopsy needle is not comprehensive, the measurement sensitivity is not high, and the applicable range is small. Therefore, we propose a one-stop pH measurement thyroid puncture biopsy needle to enrich the functions of the thyroid puncture biopsy needle. Content of the Utility Model

[0004] To solve the above technical problems of the puncture biopsy needle with an incomplete detection range, low measurement sensitivity, and small applicable range, the basic concept of the technical solution adopted by the utility model is:

[0005] A one-stop pH measurement thyroid puncture biopsy needle, including a sleeve, a puncture needle core is arranged inside the sleeve, a needle tip is arranged at the tip of the puncture needle core, the needle tip is a single-bevel conical needle, two grooves are symmetrically opened at the center of the needle tip, and a sensor is installed in the grooves to cooperate with the puncture needle core to measure the pH value of the needle tip during puncture.

[0006] As a preferred embodiment of the utility model, a handle is connected to the top end of the sleeve.

[0007] As a preferred embodiment of the utility model, an insulating diaphragm is arranged outside the puncture needle core, the puncture needle core can be disassembled and replaced in the sleeve, the insulating diaphragm adopts a KNM1000 coating, which is non-toxic, non-conductive, and has high safety performance, and the sleeve is of the model 22G*70mm.

[0008] As a preferred embodiment of the utility model, the sensor adopts an AlGaN / GaN structure, which can have high sensitivity and fast response to measure the pH value in the tissue.

[0009] As a preferred embodiment of the present utility model, the puncture needle core is made of medical stainless steel material.

[0010] The present utility model has the following beneficial effects compared with the prior art:

[0011] The present utility model measures the pH value at the tip of the needle by using a sensor, which is not affected by normal tissues during the puncture process. The groove is provided with a sensor with an AlGaN / GaN structure, which is extremely sensitive, improves the detection accuracy, has a large scope of application, is more convenient for detection, and the needle core is made of medical stainless steel material, with low cost and can be widely produced and used.
