Abstract
The utility model provides a blade replacement tool, including a cutter body and strong magnets. One side of the cutter body is provided with a handle. The other side of the cutter body relative to the handle is provided with a concave area matched with the blade, and the strong magnets are arranged in the concave area. Preferably, an assembling and disassembling groove is arranged in the concave area. The strong magnets are arranged at two sides of the groove. The blade replacement tool facilitates assembling and disassembling of the blade, prevents hand from direct contacting with a waste blade with bacteria or accidental injury by a new blade, and can effectively protect the safety of medical staff.
Description
Technical field
The utility model relates to medical field equipment, is specifically related to a kind of blade exchange instrument.
Background technology
In pathology paraffin section or frozen section process, for precision and the quality that guarantees to cut into slices, blade is changed frequently, and normally the medical personnel directly takes off old blade with hand, then newer blade is installed with hand.This method one is the old blade that allows the medical personnel contact to carry the germs of a disease, the 2nd, increased that the medical personnel is scratched by blade and the risk that infects.Directly threaten medical worker's health.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of can load and unload blade easily, can avoid again the staff directly useless blade that carries the germs of a disease of contact or the blade exchange instrument of being accidentally injured by new blade.
The technical scheme that adopts is: a kind of blade exchange instrument, comprise cutter hub and magnetic block, and be provided with handle in a side of described cutter hub, be provided with the depressed area suitable with blade at the opposite side of relatively described handle, in described depressed area, be provided with described magnetic block.
After adopting such scheme, during use, hold blade by magnetic block on the one hand, the medical worker holds handle operation, between staff and the blade across cutter hub, thereby avoid the staff directly directly useless blade that carries the germs of a disease of contact or the blade exchange instrument of being accidentally injured by new blade; In the time will laying down useless blade, only need turn down to the direction of blade along the knife back and get final product, when loading onto new blade, only need get final product locating in the depressed area of blade suction on cutter hub, thereby load and unload easily blade, and need not the contact knife sheet that directly catches during the frequent blade.
For further facilitating the useless blade of loading and unloading, establish an access recess in the depressed area, thereby when unloading piece, find easily the stressed fulcrum of turning down from the knife back to the blade direction; When load, easily blade is positioned to the depressed area.
Further, described magnetic block is two circular magnetic blocks, is positioned at the two ends of described unloading piece groove.Magnetic block is arranged on the two ends of unloading piece groove, makes that the blade two ends are stressed enough can satisfy need of work greatly.
Certainly, hilt and cutter hub can be one-body molded, are convenient to processing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further elaborated, but is not to restriction of the present utility model.
Fig. 1 is structural drawing of the present utility model;
Fig. 2 is the utility model synoptic diagram when loading onto blade.
Embodiment
Referring to Fig. 1 and a kind of blade exchange instrument shown in Figure 2, comprise handle 1, cutter hub 2 and magnetic block 5, handle 1 is " U " type and one-body molded with cutter hub 2, both make by engineering plastics, can wear-resistingly not hinder blade; The opposite side of hilt 1 is provided with depressed area 3 relatively on cutter hub 2, and the length of these depressed area 3 some depressions and length and the thickness of the degree of depth and blade are suitable, and the blade of blade 6 exposes outside the cutter hub 2.3 interposition installs an access recess 4 that is used for the conveniently assemble and disassemble blade in the depressed area, fixedly is embedded with two magnetic blocks 5 at the two ends of access recess 4.
During use, only need grasp handle, between staff and the blade across cutter hub, thereby avoid the staff directly useless blade that carries the germs of a disease of contact or the blade exchange instrument of being accidentally injured by new blade, effectively protect medical matters medical worker's safety; In the time will laying down useless blade, only need to find a stress point at the access recess place, get final product as turning down with tweezers along the direction of the knife back to blade; When loading onto new blade, only need in the depressed area of blade suction on cutter hub, and can by the access recess positioning instant.
