Abstract

The invention discloses a homogenate breaking and injecting device. The device comprises an injector and a breaker; the injector comprises an injection cylinder, the front end of the injector is provided with a push rod with a rubber plug; the breaker comprises a motor, a stirring shaft connected with the motor in a driving way and a blade arranged at the end part of the stirring shaft; another end of the push rod is of a cylindrical shape, the motor is arranged in the cylindrical push rod, the blade is arranged adjacent to the inside end plane of the rubber plug and the stirring shaft penetrates through the middle part of the rubber plug and is fixedly connected with the blade. The injector and the breaker are beneficially combined so that parathyroid glands can be completely and uniformly broken in the injector, therefore the technical problem that an existing tissue homogenate breaker is unlikely to be broken can be solved, and the step of sucking the parathyroid gland homogenate broken cannot be broken, so that the parathyroid gland homogenate can be directly injected to a receptor by the homogenate breaking and injecting device.

Description

technical field [0001] The invention relates to a medical device, in particular to a homogenate crushing injection device for conveniently crushing tiny tissues such as parathyroid glands. Background technique [0002] Parathyroid glands, located near the thyroid gland, generally have two pairs of upper and lower, located behind the lateral lobes of the thyroid gland, sometimes hidden in the thyroid parenchyma. Adult parathyroid glands are brownish-yellow flat oval, with a total weight of about 120 mg, a length of about 3-8 mm, a width of 2-5 mm, and a thickness of 0.5-2 mm. Parathyroid hormone is a peptide hormone whose main function is to affect the metabolism of calcium and phosphorus in the body, act on bone cells and osteoclasts, mobilize calcium from bone, dissolve bone salt, increase the concentration of calcium ions in the blood, and also act on In the intestines and renal tubules, the absorption of calcium is increased, thereby increasing blood calcium. Under the ...
