Abstract
The invention relates to the technical field of medical devices, in particular to an enhanced anastomat annular knife. The enhanced anastomat annular knife comprises a knife body, a knife holder and a knife edge, wherein the knife holder and the knife edge are respectively located at the rear end and the front end of the knife body, and the knife body is provided with a rib plate. According to the enhanced anastomat annular knife disclosed by the invention, the knife body is additionally provided with the rib plate, so the strength of the knife body is increased, the weight is also increased, and the inertia impact force is increased; meanwhile, the triangular bottom end of the rib plate stretches out of the plane of the knife edge, the bottom end of the rib plate can be firstly used for advancing during cutting, a gap is caused and is convenient for further cutting of the knife edge, the cutting efficiency is greatly increased, meanwhile, the pain of a patient is also relieved, and the operation quality is increased.
Description
Technical field
The present invention relates to technical field of medical instruments, especially a kind of reinforced anastomat annular cutter.
Background technology
Anastomat is the equipment medically substituting traditional-handwork stitching, endless knife is the indispensable vitals of anastomat, existing endless knife edge of a knife level, cutting completes simultaneously, making the Cutting Drag when surgical cut uses quite large, make troubles to medical personnel's operation, can not coincide needing the tissue of osculating to cut off in time, delay operating time, bring unnecessary misery and malpractice to patient.
Summary of the invention
Poor in order to overcome existing endless knife shearing force, Cutting Drag is large, and the deficiency of inefficiency, the invention provides a kind of reinforced anastomat annular cutter.
The technical solution adopted for the present invention to solve the technical problems is: a kind of reinforced anastomat annular cutter, comprises 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 provided with gusset.
According to another embodiment of the invention, comprise that gusset is parallel to be connected on the periphery of cutter hub further.
According to another embodiment of the invention, the plane of the edge of a knife is given prominence in the bottom comprising gusset further.
According to another embodiment of the invention, the bottom comprising gusset is further triangle.
The invention has the beneficial effects as follows, cutter hub adds gusset, the intensity that both improve cutter hub turn increases weight, improve inertial impact force, meanwhile, the plane of the edge of a knife is given prominence in the triangle bottom of gusset, during cutting, first the bottom of gusset makes a spurt, cause breach, facilitate the further cutting of the edge of a knife, substantially increase cutting efficiency, also mitigate the misery of patient simultaneously, improve surgical quality.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. cutter hubs, 2. tool rest, the 3. edge of a knife, 4. gusset in figure.
Detailed description of the invention
If Fig. 1 is structural representation of the present invention, a kind of reinforced anastomat annular cutter, comprises 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 provided with gusset 4.On the parallel periphery being connected to cutter hub 1 of gusset 4.The plane of the edge of a knife 3 is given prominence in the bottom of gusset 4.The bottom of gusset 4 is triangle.
Cutter hub 1 adds gusset 4, both the intensity that improve cutter hub 1 turn increases weight, improves inertial impact force, simultaneously, the plane of the edge of a knife 3 is given prominence in the triangle bottom of gusset 4, during cutting, first the bottom of gusset 4 makes a spurt, and causes breach, facilitate the further cutting of the edge of a knife 3, substantially increase cutting efficiency, also mitigate the misery of patient simultaneously, improve surgical quality.
