Abstract
The invention discloses a kind of Medical stapler and its application methods, belong to medical instruments field.Bad, the height of present invention change nail anvil concordant profipole, nail bin concordant profipole and anastomosis staple, the blood fortune organized at improvement anastomotic stricture and previous anastomotic are transported in order to solve the problems, such as to may cause the Tissue Blood at anastomotic stricture and previous anastomotic because increasing stitching tissue.
Description
Technical field
The invention belongs to the field of medical instrument technology, more particularly to a kind of Medical stapler and its application method.
Background technique
Surgical operation is usually needed two hollow organs and engaging tissue, such as kisses oesophagus stomach function regulating (or colon)
Conjunction, intestines Surgical healing, Ureteral anastomosis, fallopian tubal coincide, biliary anastomosis and vascular anastomosis etc..Traditional anastomosis be with
Suture gets up two hollow organs and engaging tissue, and effect is reliable, but cumbersome and technical requirements are high.
In recent years, with the development of stapler, can by anastomosis staple by two hollow organs or engaging tissue together.
Anastomat hemorrhoidal circumcision mode is easy to operate, and effect is reliable.
It is identical that existing stapler generally uses two nails to carry out, it is possible to it is few and lead to anastomotic leakage stitching tissue occur
Generation.Then there is a kind of three nails design, to increase stitching tissue, reduce the generation of anastomotic leakage, but be possible in this way
Lead to anastomotic stricture, and the Tissue Blood fortune at previous anastomotic is bad.How more anastomosed tissues, avoid anastomotic stricture, improve
Tissue Blood fortune at previous anastomotic is that urgent clinical needs solve the problems, such as.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides-kind of Medical stapler, not only can more stitching tissues, but also can be with
The stapler for avoiding anastomotic leakage from occurring, while improving the fortune of the Tissue Blood at previous anastomotic.
To achieve the above object, the color following technical solution of the present invention:
A kind of Medical stapler, including anastomotic part and operation portion, anastomotic part include nail bin, nail anvil, ejector pin portion and anastomosis staple,
The ejector pin portion includes pushing slice of nail, and the pushing slice of nail supports the anastomosis staple, and the nail bin is provided with nail bin hole, the nail bin
Hole accommodates the anastomosis staple, and the nail anvil is provided with nail anvil hole, and the anastomosis staple is under the promotion of the pushing slice of nail in the nail
Anvil perforations molding, the nail anvil end be provided with it is dismountable roll target seeker, and the nail bin, the nail anvil and described push away
Nail portion is provided in round two nails or round three nails.
Preferably, can by adjust two nails between spacing, come regulating nail be combined knit number.
Further, the nail bin section is low inside and high outside inclination section, and the nail anvil is that section is plane.
Further, the nail anvil section is low inside and high outside inclination section, and described be nail bin section is plane.
Further, the nail bin section is low inside and high outside inclination section, and the nail anvil is that section is low inside and high outside
Roll section.
Further, the nail bin section is plane, and the nail anvil is that section is plane.
Further, three row of the anastomosis staple height is equal.
Further, three row's height of anastomosis staple successively increases from inside to outside.
Further, three row's height of anastomosis staple successively reduces from inside to outside.
Further, the height of the anastomosis staple from inside to outside be arranged as it is high-low-in, it is low-high-in, it is medium-low-high, in-
It is high-low.
Preferably, it is carried out using the method for rolling merging body lumen identical.The nail anvil and the inclination target seeker are suitable
Lesser lumen is placed in after matching, the nail bin is then placed in biggish lumen.
Compared with prior art, the invention has the following beneficial effects: by with nail anvil head roll merging human body compared with
In lumen, then the stapler main body with nail bin is placed in biggish body lumen, two lumens are coincide.
So not only can more stitching tissues, but also can be to avoid the generation of anastomotic leakage.Meanwhile by changing nail anvil concordant profipole, nail bin kiss
The height in section and anastomosis staple is closed, the blood fortune organized at previous anastomotic is improved.
