Intraoperative trocar for parathyroid or lymph nodes

Abstract

The invention relates to a puncture device for parathyroid gland or lymph node surgery, which includes a casing; an injection device, arranged in the casing; a biasing member, arranged between the injection device and the inner wall of the casing, and its biasing force Acting on the injection device, causing the injection device to pop out of the casing for puncturing; the pressing control structure, arranged between the casing and the injection device, can prevent the injection device from ejecting, and release the injection device after pressing. With respect to the blocking of the injection device, the parathyroid or lymph node intraoperative puncture device of the present invention has the advantages of simple structure, fast and accurate puncture, convenient operation, low cost, little damage to the human body, and short time for obtaining results.

Description

technical field [0001] The invention relates to a medical device, in particular to a puncture device for parathyroid gland or lymph node operation. Background technique [0002] In recent years, the incidence of thyroid diseases has increased significantly. For thyroid malignant tumors, toxic nodular goiter, retrosternal goiter, or thyroid lesions with airway, esophagus and other surrounding tissues, the most effective treatment method is still surgery. Related studies in recent years have shown that by puncturing the surrounding tissue of the thyroid gland, detecting the concentration of parathyroid hormone (PTH) in the puncture eluate is used to identify whether it is a parathyroid gland, and by puncturing the surrounding lymph nodes of the thyroid gland, detecting the thyroid gland in the puncture fluid. The reliability and safety of identifying whether there is lymph node metastasis by protein (TG) concentration has reached a consensus. Combined with rapid detection tech...

Problems solved by technology

[0004] Then, the thyroid puncture device is punctured outside the body, because when operating without image support, the operator's hand is in a suspended state, the stability is poor, and the puncture depth is too deep or too shallow, which may affect the amount of specimens extracted. At the same time, the accuracy of puncture If the accuracy is not high, it may be inaccurate to grasp the puncture position of the organ inside the thyroid gland, which will cause damage to the human body; the thyroid puncture device is equipped with a liquid storage bottle, which not only increases the complexity of the device, but also is not conducive to saving costs; After the thyroid puncture device extracts the specimen, it needs to export the specimen and then dilute it with normal saline, which increases the operation steps and delays the time to get the test result
