Description
Technical field
The present invention relates to medical medical instruments field；Sub-assembly and its use are reinforced more particularly, to a kind of previous anastomotic
Method.
Background technology
Surgery bracing means because its can the same time quickly cutting and with closed histoorgan in patient body, phase
Than first being opened with scalpel/shearing in routine operation, largely reduce the risk of such surgical procedure, and shorten
Operating time, thus have very extensive application in surgical operation.General surgery bracing means has a jaw formula structure, generally
Including two separated arms, internal face is working face, has nail bin face and nail anvil face.Surgery bracing means can carry or not
Band has the cutter device of dissection.
In the operation of typical kiss/closer, nail bin face and nail anvil face navigate to pre-cut tissue then tightly be locked in one
Rise.User operates kiss/closer by an action process, has synchronously completed two or more staple line being sewn onto group
Knit and form a line of cut in the centre position of suture.By this way, operator, which can be, synchronously completes to tissue
Rapid suture and cutting.Then this process is stitched with suture in incision again than using operating scissors/knife to cut in routine operation
The process of conjunction is much faster.It is such a operation benefit be exactly：The wound bleeding time is reduced, and the time entirely performed the operation shortens, thus disease
People's nursing is improved significantly.
Be exactly that anastomosis staple directly contacts with the tissue of patient it is practicable directly using naked nail in some operations.Cause
For before healing, the complete tissue of patient compensates crack in itself it is prevented that anastomosis staple departs from from combination.However,
Other is performed the operation, the tissue that patient needs to suture is too fragile really, it is difficult to which anastomosis staple is fixed on corresponding position.
Such as pulmonary surgery, the lung tissue of special lesion occurs, it is necessary to which identical tissue is very fragile, under extreme case, not in some
Concordant profipole through protection easily occurs completely to tear.Surgery ruggedized equipment is used with the operation of the lung tissue of lesion increasingly
Extensively, the tissue for the protection fragility that takes measures has become to get over from being stapled nail tear or being torn in surgery sewing process
Come more important.Furthermore when kiss/closer is used, the leakage problems around anastomosis staple are also required to consider solve.
The working face of usual kiss/closer is plane, but also has a kind of kiss/closer in the prior art
(CN105078528A), should have nonplanar nail anvil face and nail bin face.Due to for this nonplanar stapler
Easily there is change in shape during back-up coat during installation and stress is produced between back-up coat different parts, be unfavorable for the peace of back-up coat
Dress；Or back-up coat and nail bin or the working face combination defective tightness of nail anvil in installation process, and cause coming off for back-up coat,
Go wrong.
The content of the invention
The technical problems to be solved by the invention are：A kind of previous anastomotic is provided and reinforces sub-assembly, previous anastomotic of the invention adds
Gu sub-assembly can not only provide enough intensity for pending tissue, prevent from suturing mouth tear, but also can be with kiss/closure
Anastomosis procedure is completed in nail bin face, the nail anvil face of device, is not limited by operating space.
The technical solution used in the present invention is：A kind of previous anastomotic is provided and reinforces sub-assembly, the previous anastomotic reinforces sub-assembly
Including previous anastomotic reinforcing member, support member and fixture, the previous anastomotic reinforcing member is arranged at the support member in a manner of bending
On at least part outer surface, previous anastomotic reinforcing member is fixed on the support member by the fixture.
Preferably, the previous anastomotic reinforcing member includes the first reinforcing portion, the second reinforcing portion and the 3rd reinforcing portion, described
One end with the first reinforcing portion, one end of the second reinforcing portion are connected respectively at the both ends of three reinforcing portions, the previous anastomotic reinforcing member bag
Include strippable coating, tack coat and one or more layers back-up coat.
Preferably, the minimum widith of first reinforcing portion and the second reinforcing portion is all higher than the 3rd reinforcing portion most
Small width.Preferably, the 3rd reinforcing portion (23) is internal and/or side is provided with one or more otch.Back-up coat is installed
During any trickle mismatch be likely to produce stress between the first reinforcing portion and the second reinforcing portion, when the 3rd reinforcing portion
When not having otch, these stress may produce distortion or fold in this place, and so as to influence the bonding of back-up coat, the present invention is by subtracting
The width of small 3rd reinforcing portion, or can be used for discharging in the otch that the 3rd reinforcing portion is set and eliminate these stress, so as to protect
Demonstrate,prove whole first reinforcing portion, the second reinforcing portion can be effectively bond in target face.
Preferably, being shaped as the otch is linear, rectangle, triangle, arc, trapezoidal middle one or more shapes
Combination.One or more otch can be set inside the 3rd reinforcing portion, and otch can be opening or joint-cutting.Alternatively, it is interior
The otch in portion and the otch of avris can be applied in combination.
Preferably, the wherein one side of the support member and the opposite in face where strippable coating in first reinforcing portion are pasted
To close, the back side of the support member is bonded with the opposite in face where strippable coating in second reinforcing portion, and the one of the support member
