Abstract
The utility model relates to a novel combined anastomosis nail, which comprises a nail column, an upper nail plate and a lower nail plate, wherein the lower end of the nail column is fixed on the lower nail plate; the upper ends of the nail posts are fixed on the upper nail plate. Combining the titanium alloy material and the stainless steel material to respectively manufacture the nail column, the upper nail plate and the lower nail plate; the nail column and the lower top plate are fixed and loaded into a nail groove of the anastomat, and the upper nail plate is arranged in a nail abutting seat of the anastomat; when in use, the tissue to be anastomosed is placed between the nail abutting seat and the nail groove, and then the percussion anastomosis operation is carried out. Because the length of the single specification nail column is fixed, when the end head of the upper end of the nail column penetrates through the nail hole, the end head can be compressed, and the diameter is reduced; when the end head passes through the nail hole, the elastic fin can automatically reset to form a reverse buckling structure, so that the phenomenon of falling off is prevented.

Technical Field
The utility model relates to the technical field of medical equipment, in particular to a novel combined anastomosis nail for an anastomat.
Background
The stapler is similar to a stapler which is mainly used for a skin stapler, a circular stapler for alimentary tracts (esophagus, stomach and intestine, and the like), a rectal stapler, a circular hemorrhoid stapler, a circumcision stapler, a blood vessel stapler, a hernia stapler, a lung cutting stapler, and the like according to the application range.
The anastomosis nail used by the anastomat is generally a titanium nail or a stainless steel nail, and the anastomosis operation is realized by utilizing the deformation characteristic of the titanium nail or the stainless steel nail. However, the titanium nail or the stainless steel nail may not be deformed in place or may be deformed too much, and particularly, when the thickness of the body tissue to be anastomosed is changed greatly, a secondary operation may be performed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of overcoming the defects of the prior art, and provides a novel combined anastomosis nail which combines titanium alloy materials and stainless steel materials to respectively manufacture a nail column, an upper nail plate and a lower nail plate; the nail column and the lower top plate are fixed and loaded into a nail groove of the anastomat, and the upper nail plate is arranged in a nail abutting seat of the anastomat; when in use, the tissue to be anastomosed is placed between the nail abutting seat and the nail groove, and then the percussion anastomosis operation is carried out. Because the length of the single specification nail column is fixed, when the end head of the upper end of the nail column penetrates through the nail hole, the end head can be compressed, and the diameter is reduced; when the end head passes through the nail hole, the elastic fin can automatically reset to form a reverse buckling structure, so that the phenomenon of falling off is prevented.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a novel combined anastomosis nail comprises a nail column, an upper nail plate and a lower nail plate, wherein the lower end of the nail column is fixed on the lower nail plate; the upper ends of the nail posts are fixed on the upper nail plate.
The upper nail plate is provided with a nail hole matched with the shape and the section size of the nail column, and the nail hole is a conical hole; the nail post comprises a post body and an end head arranged at the upper end of the nail post, elastic fins are arranged on the periphery of the end head, and the diameter formed by the outer edges of all the elastic fins is larger than the maximum inner diameter of the nail hole.
The upper nail plate and the lower nail plate are made of stainless steel materials; the nail post is made of a titanium alloy material.
The outer side of each elastic fin is arc-shaped, and the chamfer angle in each elastic fin is not more than 0.7 mm.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
combining titanium alloy materials and stainless steel materials to respectively manufacture a nail column, an upper nail plate and a lower nail plate; the nail column and the lower top plate are fixed and loaded into a nail groove of the anastomat, and the upper nail plate is arranged in a nail abutting seat of the anastomat; when in use, the tissue to be anastomosed is placed between the nail abutting seat and the nail groove, and then the percussion anastomosis operation is carried out. Because the length of the single specification nail column is fixed, when the end head of the upper end of the nail column penetrates through the nail hole, the end head can be compressed, and the diameter is reduced; when the end head passes through the nail hole, the elastic fin can automatically reset to form a reverse buckling structure, so that the phenomenon of falling off is prevented.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
FIG. 1 is a schematic view of the usage state of the present invention;
FIG. 2 is a schematic structural view of the nail column of the present invention;
FIG. 3 is a schematic view of the structure of the upper nail plate of the present invention;
FIG. 4 is a schematic structural view of a nail abutting seat.
In the figure: 1. a nail plate is arranged; 1-1, nailing holes; 2. nailing columns; 2-1, column; 2-2, end heads; 2-3, elastic fins; 3. a lower top plate; A. and (4) an upper nail plate groove.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The novel combined anastomosis nail as shown in fig. 1 to 4 comprises a nail column 2, an upper nail plate 1 and a lower nail plate 3, wherein the nail column 2 is positioned between the upper top plate 1 and the lower nail plate 3 in a use state, and the lower end of the nail column 2 is fixed on the lower nail plate 3; the upper end of the nail post 1 is fixed on the upper nail plate 1.
The upper nail plate 1 is provided with a nail hole 1-1 matched with the shape and the section size of the nail column 2, and the nail hole 1-1 is a conical hole; the nail column 2 comprises a column body 2-1 and an end head 2-2 arranged at the upper end of the nail column 2, elastic fins 2-2 are arranged around the end head 2-2, and the diameter formed by the outer edge of each elastic fin 2-3 is larger than the maximum inner diameter of the nail hole 1-1. During the anastomosis operation, the elastic fins 2-2 firstly contact the inner surfaces of the nail holes 1-1, and along with the increase of the anastomosis force, the elastic fins 2-2 are extruded and deformed, and the inner diameter is reduced until the elastic fins can smoothly pass through the nail holes 1-1. The elastic fins 2-2 are reset after passing through the nail holes 1-1, and the outer diameter of the elastic fins is larger than the diameter of the nail holes 1-1, so that the nail columns 2 cannot be separated from the upper nail plate 1.
In order to facilitate the deformation and the restoration of the elastic fins 2-2 and smoothly pass through the nail holes 1-1, deformation grooves are formed among the elastic fins 2-2, so that the deformation resistance is reduced.
Meanwhile, the elastic fins 2-2 are made of titanium alloy materials, and the elastic fins are good in resilience performance. The upper nail plate is made of stainless steel materials, so that the material cost can be effectively reduced.
The upper nail plate 1 and the lower nail plate 3 are made of stainless steel materials; the stud 2 is made of titanium alloy material.
The outer side of the elastic fin 2-2 is arc-shaped, and the chamfer angle in the elastic fin 2-2 is not more than 0.7 mm.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
