Abstract
The invention discloses an intracavitary anastomat which comprises an anastomat body, an execution head, an extension tube for connecting the anastomat body and the execution head, and an operating mechanism for controlling the action of the execution head, wherein the execution head comprises a nail anvil and a nail bin; the upper surface of the nail bin is a flat surface; the lower surface of the nail anvil at least comprises a first surface and a second surface which are parallel to each other; and the first surface is lower than the second surface. By using the technical scheme, the surfaces of the nail anvil of the intracavitary anastomat can be designed into different heights, so that the clearance between the lower surface of the nail anvil and the upper surface of the nail bin is variable. After the shooting process, B-shaped suture nails of different closed heights can be formed, thereby achieving better hemostasis effect.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of anastomat.
Background technology
The 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 just can finish.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.
Using the Chinese and foreign department doctor for the suitable attention of bleeding problems.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, and therefore, the one-tenth staple height depends on the gap between relative two surfaces with nail bin of nail anvil.
Summary of the invention
For solving above-described problem, the object of the present invention is to provide the better intracavity anastomat of a kind of haemostatic effect.
In order to reach above purpose, the technical solution used in the present invention 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, 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, and second distance with the nail bin upper surface is 1.75mm ± 0.5mm, and the 3rd distance with the nail bin upper surface is 1.5mm ± 0.5mm.
Further, respectively be provided with row's seam nail groove on first, second and the 3rd.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.
By adopting technique scheme, intracavity anastomat of the present invention becomes different height by the surface design with nail anvil, makes the nail anvil lower surface different with the gap of nail bin upper surface.After finishing percussion, form " B " shape seam nail of different shut heights, to reach better haemostatic effect.

The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
As shown in Figures 1 and 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 the embodiment as shown in Figure 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 the 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.
On first 11, be provided with row's seam nail groove 14.Similarly, also respectively be provided with row's seam nail groove on second 12 and the 3rd 13, structure is all identical with seam nail groove 14 with size, and Gu Tuzhong does not make sign.
Nail bin 20 is provided with cutter path 21, and stage property path 21 is arranged on position on the center of nail bin 20.The lower surface of nail anvil 10 is provided with and the corresponding cutter groove 15 of cutter path 21 position dimensions.
In use, be that the puncture needle of 12mm to 13mm enters the human intracavity by internal diameter earlier with Executive Head 40, rotate so that aim at identical tissue to be cut in 40 axial rotations of control Executive Head or joint, can operate clamping device, identical tissue holder to be cut is held between the nail anvil 10 and nail bin 20 of Executive Head.Operate firing lock then, make between nail anvil 10 and the nail bin 20 and reach required grip thickness, and will stitch nail and release in the nail bin 20 and penetrate clamped to be cut identical tissue and direct reach on the seam nail groove of the face that is positioned at 3 differing heights on the nail anvil 10, make the seam nail bend to " B " shape of differing heights, reach the operation purpose that tissue is coincide, cutter are pushed out via cutter path 41 simultaneously, cut clamped to be cut identical tissue, reach the operation purpose with the tissue cutting.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
