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 a cutter edge. The back end and the front end of the cutter body are provided with the cutter seat and the cutter edge respectively. Through holes are formed in the cutter body and further uniformly disposed upon the cutter edge to form a notch to allow ventilation from inside to outside. During cutting, under action of the through holes, tissues on two sides of the cutter edge are automatically separated from the cutter edge and rapidly fall off to avoid pulling the cutter body. In this way, 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 antiseized 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 antiseized anastomat annular cutter.
The technical solution adopted for the present invention to solve the technical problems is: a kind of antiseized 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 through hole.
According to another embodiment of the invention, further comprise that through hole is evenly arranged in the top of the edge of a knife.
The invention has the beneficial effects as follows, on cutter hub, offer through hole, and through hole is evenly arranged in to edge of a knife top, form breach, and guide the circulation of inner air and outer air, during cutting, under the effect that is organized in through hole of edge of a knife both sides, automatic and cutter hub departs from, and fast-falling, avoided and the pullling of cutter hub, effectively prevented the cracking of wound, greatly improve 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. through hole.
The specific embodiment
If Fig. 1 is structural representation of the present invention, a kind of antiseized 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 through hole 4.Through hole 4 is evenly arranged in the top of the edge of a knife 3.
On cutter hub 1, offer through hole 4, and through hole 4 is evenly arranged in to the edge of a knife 3 tops, form breach, and guide the circulation of inner air and outer air, during cutting, under the effect that is organized in through hole 4 of the edge of a knife 3 both sides, automatic and cutter hub 1 departs from, and fast-falling, avoided and the pullling of cutter hub 1, effectively prevent the cracking of wound, greatly improved the quality of operation, accelerated to have promoted patient's rehabilitation.
Claims (2)
