Abstract
The utility model relates to the technical field of medical equipment, in particular to a sheath-shaped anastomat annular cutter. The sheath-shaped anastomat annular cutter comprises a cutter body, a cutter rest and a cutting edge. The cutter rest and the cutting edge are located at the rear end and the front end of the cutter body respectively. A cutter sheath is arranged on the cutter body. The outer portion of the cutter body is sleeved with the tubular cutter sheath, so that in the process of cutting, the cutter sheath firstly makes contact with the tissue, location is conducted, then the cutter body falls and cuts the tissue, the cutter body retracts to the cutter sheath after cutting is completed, the residual tissue is blocked outside the cutter sheath and prevented from being dragged by the cutter body, a wound is effectively prevented from cracking, the quality of an operation is greatly improved, and the recovery of a patient is facilitated.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of sheath type 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 and hang the silk phenomenon, be unfavorable for organizing the integrity of cutting, affected the quality of operation, and patient's rehabilitation.
The utility model content
In order to overcome existing endless knife, easily produce the extension silk, the deficiency of impact operation quality, this utility model provides a kind of sheath type anastomat annular cutter.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of sheath type 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 sheath.
According to another embodiment of the present utility model, comprise that further sheath is tubulose, is enclosed within the cutter hub outside.
According to another embodiment of the present utility model, comprise that further sheath is connected with tool rest by spring.
According to another embodiment of the present utility model, comprise that further edge of a knife contracting is in sheath.
The beneficial effects of the utility model are that at the outside suit of cutter hub one tubulose sheath, sheath top is connected with tool rest by spring, bottom and cutter hub are slidably connected, and the edge of a knife contracts in sheath, during cutting, sheath is contact tissue at first, positions, and cutter hub falls subsequently, tissue is cut, and complete rear retraction sheath, will organize remaining gear outside sheath, 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.
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. sheath.
The specific embodiment
As Fig. 1, be structural representation of the present utility model, a kind of sheath type 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 provided with sheath 4.Sheath 4 is tubulose, is enclosed within cutter hub 1 outside.Sheath 4 is connected with tool rest 2 by spring.The edge of a knife 3 contractings are in sheath 4.
At the sheath 4 of cutter hub 1 outside suit one tubulose, sheath 4 tops are connected with tool rest 2 by spring, and bottom and cutter hub 1 are slidably connected, the edge of a knife 3 contractings are in sheath 4, and during cutting, sheath 4 is contact tissue at first, position, cutter hub 1 falls subsequently, and tissue is cut, complete rear retraction sheath 4, to organize remaining gear outside sheath 4, avoid and the pullling of cutter hub 1, effectively prevent the cracking of wound, greatly improve the quality of operation, accelerated to have promoted patient's rehabilitation.
