Description
Technical Field
The invention belongs to the technical field of medical instrument tissue cutting tools, and particularly relates to a compass type cervical coning cutter.
Background
When soft tissues are studied routinely, experimenters often need to cut soft tissues of fixed sizes, but soft tissues have greater elasticity, and especially when soft tissues are thinner, it is difficult to ensure the consistency of the sizes of samples after cutting by using a traditional single-blade sequential cutting method. For example, when it is required to cut a conical muscle tissue having a diameter of about 1cm, it is difficult for the conventional cutting method to ensure that the obtained size reaches the standard, and thus the accuracy of the subsequent measurement is affected.
The Chinese patent document CN201521101302.4 discloses a hard tissue cutting machine, which comprises a base, a cutter cutting frame and a fixed clamping plate, wherein the cutter cutting frame is fixed on the base, a motor, an electric saw handle and a saw blade shield are arranged on the cutter cutting frame, a net-shaped double saw blade is arranged in the saw blade shield, the double saw blade is connected on the cutter cutting frame through a bearing, an output shaft of the motor is in transmission connection with a rotating shaft of the double saw blade, a distance limiting module is arranged between the double saw blades, one side of the distance limiting module is fixed on one of the double saw blades, the other side of the distance limiting module is connected with the other saw blade of the double saw blade through a locking component, an ejecting component is arranged on one side of the saw blade shield, and the ejecting component is connected with the locking component through an elastic component; the fixed clamping plates are respectively positioned at two sides below the saw blade shield, and a dust collection bin is arranged between the two supports.
The above patent document can cut hard tissue once to obtain a tissue slice, and the slice thickness is uniform to improve the diagnosis rate, but the hard tissue applied to primary cell culture has: because of the structural limitation, the operation can only be performed in the super clean bench, and the cutting outside the super clean bench can cause tissue pollution, thereby causing experimental failure. The cutting direction is single, and the cutting is realized by setting the distance of the double saw blades in the patent literature, and the hard tissue for primary cell culture needs to be cut into uniform tissue blocks from different directions to meet the requirements.
