Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of bullet cut anastomat annular cutter.
Background technology
Anastomat is medically to substitute the equipment that traditional-handwork is sewed up, endless knife is the indispensable vitals of anastomat, existing endless knife edge of a knife level, and cutting completes simultaneously, active force directly transmits, there is no change curve, make when surgical cut is used cutting stiff, resistance is quite large, to medical personnel's operation, make troubles, can not in time the tissue that needs osculating be cut off and coincide, delay operating time, to patient, bring unnecessary misery and malpractice.
The utility model content
Poor in order to overcome existing endless knife shearing force, Cutting Drag is large, the deficiency of inefficiency, and this utility model provides a kind of bullet cut anastomat annular cutter.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of bullet cut anastomat annular cutter, comprise cutter hub, tool rest and the edge of a knife, and tool rest and the edge of a knife lay respectively at rear end and the front end of cutter hub, and cutter hub is connected with tool rest by spring housing.
According to another embodiment of the present utility model, comprise that further tool rest is tubulose, is inserted in cutter hub.
According to another embodiment of the present utility model, comprise that further spring housing is enclosed within on tool rest.
According to another embodiment of the present utility model, comprise that further the upper end of spring housing is connected with tool rest, lower end is connected with cutter hub.
The beneficial effects of the utility model are, cutter hub is connected with tool rest by spring housing, form an elasticity cutting knife, during cutting, active force has a progressive change procedure, and full of potential, greatly improved cutting efficiency, simultaneously, the resilience after helping cutter hub cutting complete resets, alleviate patient's misery, improved the operation quality.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. cutter hubs in figure, 2. tool rest, the 3. edge of a knife, 4. spring housing.
The specific embodiment
As Fig. 1, be structural representation of the present utility model, a kind of bullet cut anastomat annular cutter, comprise cutter hub 1, tool rest 2 and the edge of a knife 3, and tool rest 2 and the edge of a knife 3 lay respectively at rear end and the front end of cutter hub 1, and cutter hub 1 is connected with tool rest 2 by spring housing 4.Tool rest 2 is tubulose, is inserted in cutter hub 1.Spring housing 4 is enclosed within on tool rest 2.The upper end of spring housing 4 is connected with tool rest 2, and lower end is connected with cutter hub 1.
Cutter hub 1 is connected with tool rest 2 by spring housing 4, form an elasticity cutting knife, during cutting, active force has a progressive change procedure, and full of potential, has greatly improved cutting efficiency, simultaneously, resilience after helping cutter hub 1 cutting complete resets, and has alleviated patient's misery, has improved the operation quality.
