Abstract
The utility model discloses a cutting knife of an anastomat. The anastomat is provided with a ring casing-shaped knife body. One end of the ring casing-shaped knife body is provided with a cutting edge, two side walls of the cutting edge are both arc, and a top included angle Alpha formed by the two side walls is 20-70 degrees. The bottom of the ring casing-shaped knife body is provided with an inner folded edge. Or, two side walls on the top of the cutting edge form an acute angle, the top side walls of the cutting edge are in arc transition with the lower side wall, and the top included angle Beta formed by the top two side walls is 20-70 degrees. The cutting knife of the anastomat not only is high in strength of the cutting edge, but also prevents abrasion of the cutting edge and is high in the safety of an operation.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of cutter of anastomat.
Background technology
The sidewall of the cutter blade of existing anastomat is type linearly, the angle of two side is generally 5 °～10 °, because the angle at the tip of cutter blade is less, makes lifting surface area less, thereby the intensity of blade is little, blade is easy to wear, and during again owing to cutter and pushing slice of nail assembling, cutter rock in pushing slice of nail easily, fastness is poor, during operation, the phenomenon that blade can occur rupturing, operation has certain danger.
The utility model content
The purpose of this utility model is: provide a kind of not only edge strength big, prevent the blade wearing and tearing, and with the cutter of the good anastomat of tool rest assembling fastness.
In order to achieve the above object, the technical scheme that this utility model is first kind is: a kind of cutter of anastomat, have ring set shape cutter hub, and an end of described ring set shape cutter hub has blade, the two side of described blade is all curved, and the top angle α that the two side forms is 20 °～70 °; The bottom of described ring set shape cutter hub has interior flanging.
Have 4 gap on the interior flanging of described ring set shape cutter hub.
The top angle α that described blade two side forms is 60 °.
In order to achieve the above object, the technical scheme that this utility model is second kind is: a kind of cutter of anastomat, has ring set shape cutter hub, one end of described ring set shape cutter hub has blade, the two side at described blade top forms acute angle, the top sidewall of blade and lower wall arc-shaped transition, the top angle β that the two side at top forms is 20 °～70 °; The bottom of described ring set shape cutter hub has interior flanging.
Have 4 gap on the interior flanging of described ring set shape cutter hub.
The top angle β that the two side at described blade top forms is 60 °.
The beneficial effect that this utility model had is: because the two side of the cutter blade of this utility model anastomat is all curved, the top angle α that the two side forms is 20 °～70 °, perhaps the two side at blade top forms acute angle, the top sidewall of blade and lower wall arc-shaped transition, the top angle β that the two side at top forms is 20 °～70 °, increased the lifting surface area of cutter, strengthened the intensity of blade, and the wearing and tearing of blade have been reduced, prevent that effectively the phenomenon of fracture, operation safety height from appearring in blade; Again because the bottom of described ring set shape cutter hub has interior flanging, the interior flanging of cutter and pushing slice of nail once injection moulding and be fixed together, both fastnesses are good, are not prone to the phenomenon of rocking.

The specific embodiment
Below in conjunction with the embodiment that accompanying drawing provides, the utility model is described in further detail.
As shown in Figure 1, 2, 3, a kind of cutter of anastomat have ring set shape cutter hub 1, and an end of described ring set shape cutter hub 1 has blade 1-1, and the two side 1-1-1 of described blade 1-1 is all curved, and the top angle α that two side 1-1-1 forms is 20 °～70 °; The bottom of described ring set shape cutter hub 1 has interior flanging 1-2.Wherein, the top angle α of described blade 1-1 two side 1-1-1 formation is 60 ° of the bests.
As shown in Figure 1, 2, in order further to improve the fastness of cutter and pushing slice of nail assembling, have 4 gap 1-2-1 on the interior flanging 1-2 of described ring set shape cutter hub 1.
Embodiment 2
Shown in Fig. 4,5, a kind of cutter of anastomat, has ring set shape cutter hub 1, one end of described ring set shape cutter hub 1 has blade 1-1, the two side 1-1-1 at described blade 1-1 top forms acute angle, the top sidewall 1-1-1 of blade 1-1 and lower wall 1-1-2 arc-shaped transition, the top angle β that the two side 1-1-1 at top forms is 20 °～70 °; The bottom of described ring set shape cutter hub 1 has interior flanging 1-2.Wherein, the top angle β that forms of the two side 1-1-1 at described blade 1-1 top is 60 ° of the bests.
As shown in Figure 4, in order further to improve the fastness of cutter and pushing slice of nail assembling, have 4 gap 1-2 '-1 on the interior flanging 1-2 of described ring set shape cutter hub 1.
The cutter blade of anastomat of the present utility model improves the cutter that also are applicable to other kind shape, and is applied widely, when the doctor operates, and the operation safety height.
