Abstract

The utility model discloses a kind of fixed structure of small dimension tubular anastomat endless knife, the endless knife comprise pushing slice of nail, being connected with pushing slice of nail, pushing slice of nail has the step through-hole run through, the aperture of endless knife laminating step through-hole upper end penetrates, internal projecting ring is provided with in described step through-hole, be close to bottom endless knife on internal projecting ring, endless knife lower side has at least two inverted evagination wings, and evagination wing is fastened on the step place between the large aperture of step through-hole.This utility model arranges evagination wing in endless knife, utilize and to block between evagination wing with pushing slice of nail step through-hole and be connected, thus effectively realizing, on the fixing basis of small dimension endless knife and pushing slice of nail, releasing endless knife inner space, meeting the basic demand of anastomosis operation.

Description

The fixed structure of small dimension tubular anastomat endless knife
Technical field
This utility model relates to technical field of medical instruments, especially a kind of fixed structure of small dimension tubular anastomat endless knife.
Background technology
Be mainly used in end to end anastomosis and the end-to-side anastomosis of the digestive tract such as esophagus, gastrointestinal tissue compared with the tube type anastomat of large gauge, the tubular anastomat of small dimension is then mainly applicable to coincideing of biliary tract, child's esophagus and intestinal etc.For the anastomat that specification is larger, if diameter is more than 26, because installing space is larger, endless knife in its anastomosis cut component and the connection between pushing slice of nail, the hot pick mode of routine that adopts is fixed more, but for the tubular anastomat of small dimension, if diameter is 14mm, 17mm, because diameter is less, installing space is restricted, and usual manner cannot be adopted to realize effectively fixing between endless knife and pushing slice of nail.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of can effectively stationary annular cutter, meet the fixed structure of the small dimension tubular anastomat endless knife of operation technique space requirement.
This utility model solves the technical scheme that its technical problem adopts: a kind of fixed structure of small dimension tubular anastomat endless knife, the endless knife comprise pushing slice of nail, being connected with pushing slice of nail, pushing slice of nail has the step through-hole run through, the aperture of endless knife laminating step through-hole upper end penetrates, internal projecting ring is provided with in described step through-hole, be close to bottom endless knife on internal projecting ring, endless knife lower side has at least two inverted evagination wings, and evagination wing is fastened on the step place between the large aperture of step through-hole.
Preferably, described evagination wing quantity is two.
The beneficial effects of the utility model are: this utility model arranges evagination wing in endless knife, utilize and to block between evagination wing with pushing slice of nail step through-hole and be connected, thus effectively realizing on the fixing basis of small dimension endless knife and pushing slice of nail, release endless knife inner space, meet the basic demand of anastomosis operation.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. pushing slice of nail 2. endless knife 3. step through-hole 4. internal projecting ring 5. evagination wings in figure
Detailed description of the invention
By reference to the accompanying drawings this utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with this utility model.
The fixed structure of a kind of small dimension tubular anastomat endless knife as shown in Figure 1, the endless knife 2 comprise pushing slice of nail 1, being connected with pushing slice of nail 1, pushing slice of nail 1 has the step through-hole 3 run through, the fit aperture of step through-hole 3 upper end of endless knife 2 penetrates, internal projecting ring 4 is provided with in described step through-hole 3, be close on internal projecting ring 4 bottom endless knife 2, endless knife 2 lower side has two inverted evagination wings 5, and evagination wing 5 is fastened on the step place between the large aperture of step through-hole 3.
During installation, the step place clamping between the large aperture first endless knife 2 being snapped in step through-hole 3 by its evagination wing 5, is then arranged on nail bin on pushing slice of nail 1, finally they is inserted in together in nail storehouse sleeve, complete the installation of nail bin groupware.
Tubular anastomat difficulty in making of small dimension is large, wherein in nail bin groupware, the fixed form of endless knife 2 is bottlenecks, the fixed form of various routine is subject to the restriction of tight working spaces, and this utility model by arranging evagination wing 5 in endless knife 2, utilize and to block between evagination wing 5 and the step through-hole 3 of pushing slice of nail 1 and be connected, thus effectively realizing, on small dimension endless knife 2 basis fixing with pushing slice of nail 1, releasing endless knife 2 inner space, meeting the basic demand of anastomosis operation.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to this utility model spirit change or modify, and all should be encompassed in protection domain of the present utility model.
