Problems solved by technology

[0002] Technical background: In the current placenta preparation process, ordinary surgical scissors are generally used to prepare and cut into pieces, which can only be performed by a single person at a time. In this preparation process, time resources and human resources are greatly wasted, resulting in too long preparation time and manpower. In the case of excessive consumption, in order to improve work efficiency, more manpower will be added to the operation to reduce the waste of time and resources, but this wastes human resources, and the personnel are all operating in a biological safety cabinet, which greatly increases the chance of contamination and also Unfavorable for batch operation, increasing cost consumption
[0003] The current closest technical solution: At present, a small part of the preparation technology uses a traditional homogenizer for crushing, but the purchase cost of the homogenizer is very high, the consumables are expensive, and the equipment is inconvenient to clean, and one homogenizer can only operate one at a time For samples, after the operation is completed, the equipment must be cleaned separately, and it is inconvenient to sterilize and sterilize, and it is impossible to prepare the next sample immediately, and it is easy to cause pollution, and it is not conducive to the preparation and production of large-scale samples

Abstract

The invention discloses a detachable handheld crusher. The detachable handheld crusher comprises a crusher body. The crusher body comprises a handheld device, a start device, a rotating device, a gearset and a turbine device. The handheld device comprises a handle and a base. The start device is arranged at the position of the handle. The start device comprises a start gear, an extension hook, anut and an extension spring. The start gear is connected with the drive gear set, the other end of the gear set is connected with the turbine device, and the turbine device comprises bearings, a turbine fixing device and a clamping groove device. Manpower consumption caused by manual cutting-up and the purchase cost of a pulp refiner are reduced, the crushing rate is stably controlled, the operation contamination probability is reduced, the material consumption is reduced, the preparation time is shortened, and the working efficiency is improved. The common pulp refiner can be more convenient,the use convenience of the pulp refiner is kept, the use process is more convenient and rapider, the working efficiency and the cutting-up degree are improved, and too long preparation time and wasteof reagent consumables caused by human factors and equipment are reduced. The detachable handheld crusher does not need to be charged, and can be used at any time.
