Abstract
The utility model relates to an anastomat annular cutter, which comprises an annular cutter body. The upper end of the annular cutter body is provided with an annular cutter edge, and the annular cutter edge is an annular serrated cutter edge. The utility model provides the anastomat annular cutter with small cutting resistance, which can effectively reduce the percussion force of an anastomat.
Description
Technical field
This utility model relates to a kind of anastomat endless knife, belongs to technical field of medical instruments.
Background technology
Anastomat, the equipment of the alternative traditional-handwork stitching of promptly medically using, endless knife is the indispensable vitals of anastomat.The percussion power that anastomat is bigger is one of main shortcoming of anastomat, because endless knife is the important component part of anastomat percussion power to the cutting force of tissue, if cutting force can be reduced, then can reduce percussion power preferably, thereby alleviate the phenomenon of the bigger percussion power of anastomat.The existing endless knife edge of a knife is neat, and cutting is finished simultaneously, makes that the cutting resistance is quite big, thereby causes the bigger percussion power of anastomat, has not only increased patient's misery, has also increased the operation easier of product.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the defective that exists in the background technology, provide a kind of little anastomat endless knife of resistance of cutting, make it can effectively reduce anastomat percussion power.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of anastomat endless knife, comprise annular cutter hub, and described annular cutter hub upper end is provided with the annular edge of a knife, and it is characterized in that: the described annular edge of a knife is the circular saw edge of a knife.
Further, the described annular edge of a knife is the annular circular arc sawtooth edge of a knife, has so further reduced the cutting resistance of the edge of a knife, thereby has reduced the percussion power of anastomat.
Beneficial effect: after adopting said structure, earlier by the some cutting, realize the line cutting by the stress concentration principle again, thereby finish whole cutting process, reduce the cutting resistance of endless knife effectively, greatly reduce cutting force, thereby reach the purpose that reduces anastomat percussion power, patient again needn't bear unnecessary misery, doctor's more convenient operation, and it is successfully more secure to perform the operation.
Description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
Fig. 1 is the main TV structure sketch map of the preferred embodiment of anastomat endless knife;
Fig. 2 is the perspective view of the preferred embodiment of anastomat endless knife.
Wherein: 1, annular cutter hub; 2, the annular edge of a knife.
The specific embodiment
This utility model relates to a kind of anastomat endless knife, it is a kind of and the matching used surgical cut cutter of anastomat, it comprises annular cutter hub 1, described annular cutter hub 1 upper end is provided with the annular edge of a knife 2, the annular edge of a knife 2 is the circular saw edge of a knife, in order to slow down the resistance of the edge of a knife further, most preferred embodiment of the present utility model is that the annular edge of a knife 2 is the annular circular arc sawtooth edge of a knife.
After adopting said structure,, utilize the stress concentration principle to realize the line cutting again, thereby finish whole cutting process, reduced the cutting resistance effectively, greatly reduce cutting force, thereby reached the purpose that reduces anastomat percussion power earlier by the some cutting.
