Abstract

The invention relates to the technical field of medical instruments, in particular to a parathyroid gland homogenate breaker. The parathyroid gland homogenate breaker comprises a syringe, a piston, amotor, a blade and a driving mechanism. The piston comprises a piston body and a push-pull rod, the piston body is used for being in circumferential sealing fit with the inner wall of the syringe, andthe push-pull rod is used for driving the piston body to axially move along the inner wall of the syringe; an accommodating groove is formed in one end of the piston body, and a penetrating through hole is formed in the bottom surface of the accommodating groove; the motor comprises a machine body and a motor shaft arranged on the machine body, and one end of the motor shaft is used for penetrating through the through hole and is connected with the blade; and the driving mechanism is used for driving the machine body to move relative to the piston body to drive the blade to extend or retractinto the accommodating groove, and when the blade retracts into the accommodating groove, the blade is in circumferential sealing fit with the groove wall of the accommodating groove. According to thetechnical scheme, when parathyroid gland homogenate is injected, the piston can be pushed to the bottom of the syringe, and therefore residues of the parathyroid gland homogenate in the syringe can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a parathyroid homogenate breaker. Background technique [0002] The parathyroid glands are located near the thyroid gland, generally there are two pairs of upper and lower, located behind the lateral lobes of the thyroid gland, sometimes hidden in the thyroid parenchyma, which can secrete parathyroid hormone. Among them, the abnormal secretion of parathyroid hormone will cause the abnormal ratio of calcium and phosphorus in the blood. Therefore, the determination of parathyroid hormone has important clinical value for early prediction of the occurrence of calcemia after total thyroidectomy. In previous experiments or detection steps, it was often necessary to use a homogenizer to crush the parathyroid glands. [0003] Such as figure 1 As shown, there is an existing parathyroid homogenate breaker, which includes a syringe 10 and a breaker 20. The syringe 10 includes ...
