Abstract
The utility model discloses an intracavity anastomat, which comprises an anastomat body, an executing head, an extending pipe for connecting the anastomat body and the executing head and an operation mechanism for controlling movement of the executing head. The executing head comprises a nail anvil and a nail bin, and the upper surface of the nail bin is a plane. The lower surface of the nail anvil is at least composed of a first face and a second face which are parallel to each other, and the first face is lower than the second face. By means of the technical scheme, gaps formed on the lower surface of the nail anvil are different from gaps formed on the upper surface of the nail bin due to the fact that the surface of the nail anvil is designed to be in different height. After percussion is finished, B-shaped stitching nails with different closing height are formed, thereby achieving good blood stopping effect.
Description
Technical field
this utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of anastomat.
Background technology
intracavity linear cutting anastomat is a considerable a surgical instruments in the endoscope-assistant surgery, uses this apparatus, can reduce operating time, improves the operation quality, and many reconstruction of digestive tract operations all must have this apparatus to accomplish.Existing chamber mirror surgical cutting anastomat has the various chambeies mirror surgical cutting anastomat of introducing in United States Patent (USP) 20080308602,20090206124 and 20090206137.
The Chinese and foreign department doctor is being used for the suitable attention of bleeding problems in
.Many producers all adopt the mode of three row's seam nails to prevent to bring out blood cutting of tissue.But single row's number that increases the seam nail that relies on can not be dealt with problems fully, and the molding of seam nail is highly also very important to hemostasis.And the height theory of seam nail is consistent, therefore, becomes staple height to depend on the gap between relative two surfaces with nail bin of nail anvil.
Summary of the invention
For solving above-described problem, the purpose of this utility model is to provide a kind of haemostatic effect better intracavity anastomat
.
are in order to reach above purpose; The technical scheme that this utility model adopts is: the intracavity anastomat; It comprises the extension of anastomat body, Executive Head, connection anastomat body and Executive Head and the operating mechanism of control Executive Head action, and Executive Head comprises nail anvil and nail bin, nail bin with the nail anvil facing surfaces be its upper surface; This upper surface is the plane; Nail anvil with the nail bin facing surfaces be its lower surface, this lower surface comprises first and second at least, first and second face is parallel to each other and first face is lower than second.
preferably, the lower surface of nail anvil also comprises the 3rd that parallels with first and second face.
more preferably, second face is lower than the 3rd.
further, adjacent two is not 0.15mm～0.25mm apart from difference between conplane.
preferably, first face is positioned at second the outside, and second face is positioned at the 3rd the outside.
more preferably, first distance with the nail bin upper surface is 2.0mm ± 0.5mm, second distance with the nail bin upper surface is 1.75mm ± 0.5mm, the 3rd distance with the nail bin upper surface is 1.5mm ± 0.5mm.
respectively are provided with row's seam nail groove on first, second and the 3rd further.After the percussion, the seam nail is pushed out nail bin, and the interior natural torsion of seam nail groove that is hampered by nail anvil is " B " font.
further, nail bin is provided with cutter path, and the lower surface of nail anvil is provided with and the corresponding cutter groove of cutter path position dimension.
Through adopting technique scheme, this utility model intracavity anastomat becomes different height through the surface design with nail anvil, makes the nail anvil lower surface different with the gap of nail bin upper surface
.After accomplishing percussion, form " B " shape seam nail of different shut heights, to reach better haemostatic effect.

The specific embodiment
Set forth preferred embodiment of the present invention below in conjunction with accompanying drawing in detail
, thereby so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
like accompanying drawing 1 with shown in the accompanying drawing 2, the intracavity anastomat, it comprises anastomat body 30, Executive Head 40, connects the extension 50 of anastomat body 30 and Executive Head 40 and the operating mechanism of control Executive Head action.Executive Head 20 comprises nail anvil 10 and nail bin 20.Operating mechanism comprises the clamping device of control nail anvil 10 and nail bin 20 closures and the firing lock of control ejector pin.
The upper surface of
nail bin 20 is the plane, the lower surface of nail anvil 10 comprise first 11 and second 12, the first 11 and second 12 at least and be parallel to each other and first 11 be lower than second 12.
Among
embodiment shown in accompanying drawing 2, the lower surface of nail anvil 10 comprises 3 faces, promptly be parallel to each other first 11, second 12 and the 3rd 13.In the present embodiment, 3 faces all not at grade, first 11 is lower than second 12, the second 12 and is lower than the 3rd 13.Consider problems such as staple height, haemostatic effect, adjacent two is not 0.15mm～0.25mm apart from difference between conplane.
according to industry standard, the distance of the upper surface of the lower surface of nail anvil 10 and nail bin 20 is 1.75mm.Because of the lower surface of nail anvil 10 has three height, should with the plane that is positioned at intermediate altitude datum level.
In
present embodiment, adjacent two is not 0.25mm apart from difference between conplane.First 11 distance with nail bin 20 upper surfaces is 2.0mm, and second 12 distance with nail bin 20 upper surfaces is 1.75mm, and the 3rd 13 distance with nail bin 20 upper surfaces is 1.5mm.
