Abstract
The invention relates to technical field of medical instruments, particularly to an anti-sticking annular cutter of an anastomat. The anti-sticking annular cutter comprises a cutter body, a cutter seat and cutter edges. The back end and the front end of the cutter body are provided with the cutter seat and the cutter edges respectively. The cutter body is provided with double wing-type retainers which are vertically connected to the cutter body. During cutting, under action of the retainers, tissues on two sides of the cutter opening which are stopped under the action of the retainers to avoid large-area sticking with the cutter body is compressed to be separated from the cutter body and rapidly fall off to avoid pulling the cutter body. In this way, the wound dehiscence is effectively prevented, surgery quality is greatly improved, and recovery of patients is accelerated.
Description
Technical field
The present invention relates to technical field of medical instruments, especially a kind of anti-silk 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, the existing endless knife edge of a knife is mostly double-sided blade, during cutting, easily pull tissue, cause hanging wire phenomenon, the integrity that is unfavorable for tissue cutting, has affected the quality of performing the operation, and patient's rehabilitation.
Summary of the invention
In order to overcome existing endless knife, easily produce hanging wire, the deficiency of impact operation quality, the invention provides a kind of anti-silk anastomat annular cutter.
The technical solution adopted for the present invention to solve the technical problems is: a kind of anti-silk 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 provided with baffle plate.
According to another embodiment of the invention, further comprise that baffle plate is double-vane shape, is vertically connected on cutter hub.
According to another embodiment of the invention, further comprise that baffle plate is positioned at the inside and outside both sides of edge of a knife top.
The invention has the beneficial effects as follows, the vertical baffle plate that connects double-vane shape on cutter hub, baffle plate is positioned at the inside and outside both sides of edge of a knife top, form a cover plate, during cutting, under the effect that is organized in baffle plate of edge of a knife both sides, be blocked in the region of baffle plate below, the large area adhesion of prevention and cutter hub, departs from itself and cutter hub by compression, and fast-falling, avoided and the pullling of cutter hub, effectively prevent the cracking of wound, greatly improved the quality of operation, accelerated to have promoted patient's rehabilitation.
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 in figure, 2. tool rest, the 3. edge of a knife, 4. baffle plate.
The specific embodiment
If Fig. 1 is structural representation of the present invention, a kind of anti-silk 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 baffle plate 4.Baffle plate 4 is double-vane shape, is vertically connected on cutter hub 1.Baffle plate 4 is positioned at the inside and outside both sides of the edge of a knife 3 tops.
The vertical baffle plate 4 that connects double-vane shape on cutter hub 1, baffle plate 4 is positioned at the inside and outside both sides of the edge of a knife 3 tops, forms a cover plate, during cutting, under the effect that is organized in baffle plate 4 of the edge of a knife 3 both sides, be blocked in the region of baffle plate 4 belows, stop the large area adhesion with cutter hub 1, by compression, itself and cutter hub 1 are departed from, and fast-falling, avoided and the pullling of cutter hub 1, effectively prevented the cracking of wound, greatly improve the quality of operation, accelerated to have promoted patient's rehabilitation.
