Preferably, the present invention further provides:
And the middle parts of the left operating rod and the right operating rod are connected by fixing screws.
The total length of the tissue disruptor body is 25 cm.
The length of the blade part bit is 15cm, wherein the length of a single blade is 10cm, and the length of a combined blade is 5 cm.
The length of the handheld part is 10 cm.
The distance between the nine groups of knife edges is 3 mm.
The tissue disruptor body is made of non-toxic and harmless PVE plastic, the single blade and the combined blade are made of 304 stainless steel, and the metal blades are all embedded on the PVE and exposed for 5 mm.
The single cutting edge and the combined cutting edge are both provided with a cover body which is respectively a single cutting edge guide sleeve and a combined cutting edge guide sleeve.
The utility model provides a multifunctional disposable scissors, which can separate partial tissues from living tissues and cut the tissues in vitro into pieces. The operation of technicians is convenient, the workload is reduced, and meanwhile, the pollution and the cross pollution are avoided to the maximum extent.
The multifunctional tissue disruptor main body is a disposable irradiation sterile pyrogen-free scissors, the cutting edge is divided into two parts, the lower end of the cutting edge to 1/5 is a rake-shaped tissue disruptor formed by compounding a plurality of cutting edges, and the cutting edge 1/5 is the cutting edge of a common surgical scissors which is arranged from the position to the uppermost end of the cutting edge. The experiment operator can separate the tissue by a common blade and break the tissue by a harrow-shaped tissue breaker. The utility model discloses product low in production cost optimizes the apparatus structure, reduces complex operation degree, uses manpower sparingly the resource, reduces personnel's fault rate, and the pollution abatement probability improves production efficiency.
