Puncture outfit used in parathyroid hormone or lymph gland operation

Abstract

The invention relates to a puncture outfit used in a parathyroid hormone or lymph gland operation. The puncture outfit comprises a shell, an injection device arranged in the shell, an eccentric pressing component and a pressing control structure. The eccentric pressing component is arranged between the injection device and the inner wall of the shell, and the eccentric pressure acts on the injection device so that the injection device can pop out of shell to conduct puncturing. The pressing control structure is arranged between the shell and the injection device and can prevent the injection device from popping out, and blocking to the injection device is released after the pressing control structure is pressed. The puncture outfit used in the parathyroid hormone or lymph gland operation is simple in structure, fast and accurate in punching, convenient to operate, low in cost, small in damage to the human body and short in result obtaining time.

Description

technical field [0001] The invention relates to a medical device, in particular to a puncture device for parathyroid hormone 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 te...

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
