Abstract
The utility model discloses a kind of staple for stapler, inside includes 1 or more hollow channel.The channel is completely contained in the initial state in the staple, and when the staple compressive deformation, the channel is communicated with the outside world.The cross section in the staple and the channel at least one be non-circular.Contain antimicrobial in channel.Staple formation stability can be improved, and reduce the risk of postoperative hemorrhage and infection.
Description
Technical field
The utility model relates to surgical operating instrument technical fields, more particularly to a kind of staple for stapler.
Background technique
With the development and research and development of products of medicine, stapler is widely used in gastrointestinal surgery, liver and gall surgical department, thoracic surgery, secretes
The every field such as surgery, gynemetrics are urinated, one of essential tool of doctor is become.
The working principle of stapler is identical as stapler, i.e., percussion is implanted into multiple rows of staple to intermesh to group into tissue
It knits and carries out multiple rows of intersection stapling, suture is tight, prevents from leaking.The staple of original state, substantially U-shaped, stapler closure percussion
When, staple, which is pushed to be pierced by pushing slice of nail, is sewn tissue, B shape is then inwardly closed under resist-nailed seat effect, fixation is sewn
Tissue realizes engaging tissue.Since thin vessels can pass through from the gap of " B " shape staple, therefore suturing part and its remote is not influenced
The blood supply at end.Compared with manual suture line, stitching speed is fast, reduces patient's pain.Due to staple marshalling, spacing phase
Deng suture elasticity is controlled by scale, and avoiding manual suture, to dredge overstocked and ligation tension excessively excessively loose, therefore ensure that tissue is good
Good healing.
Currently used staple cross section is circle, in stapler closure staple forming process, for being led by tissue
External forces, the staple such as draw to be easy to happen torsion and dislocation, thus can not good closure be sewn tissue, and then cause previous anastomotic
The complication such as fistula.
Utility model content
The technical problem to be solved by the present invention is to provide the staple for stapler of a kind of anti-torsion and dislocation, from
And overcome the shortcomings of existing staple, staple formation stability is improved, and reduce the risk of postoperative hemorrhage and infection.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of staple for stapler, internal
Include 1 or more hollow channel.
The channel is completely contained in the initial state in the staple, when the staple compressive deformation, the channel
It communicates with the outside world.
The cross section in the staple and the channel at least one be non-circular.
The staple and/or the channel cross-section are greater than along the staple width direction distance along the staple length side
To distance.
Preferably, the staple cross section includes circle, ellipse, triangle, quadrangle.
Preferably, the channel cross-section includes circle, ellipse, triangle, quadrangle.
Contain antimicrobial in the channel.
Preferably, the antimicrobial includes halogenated hydroxy ether, acyloxy diphenyl ether and their combination.
Preferably, the antimicrobial is selected from Octenidine, PHMB, triclosan, copper, silver, gold, selenium, gallium, ox sulphur sieve
Fixed, 2- (chloro amido) ethanesulfonic acid, alcohol, LAE, MAPD, OAPD and their mixture.
The staple material is selected from titanium, tantalum, magnesium alloy.
The beneficial effects of the utility model are: the utility model is used for the staple of stapler, using noncircular cross section and/or
Channel, by staple stress bending process, reducing staple using own form in the yield strength of desired bending position, from
And staple is made to be easier to deform in desired position, and be not easy to twist, and then realize good " B " font forming effect
Fruit reduces the generation of anastomotic leakage complication.Simultaneously by injecting antimicrobial into tissue, postoperative hemorrhage and infection are reduced
Possibility.

Specific embodiment
The utility model provides a kind of staple for stapler, in order to make those skilled in the art more fully understand this
The technical solution of utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
[embodiment 1]
Referring to shown in attached drawing 1 to 3, embodiment according to the present utility model, for including 2 inside the staple 1 of stapler
Hollow channel 2.Channel 2 is completely contained in the initial state in staple 1；After stapler, which is closed, to be fired, staple 1 is by buckling
Shape, nail leg tail end section are broken, and channel 2 communicates with the outside world at this time.
1 cross section of staple is semicircle, and its outer surface is plane.2 cross section of channel is circle.Due to 1 section of staple
Width direction distance is greater than length direction distance.Therefore when nail leg is pressurized, staple 1 reaches up to bending resistance in relatively thin side first
Ultimate strength simultaneously curves inwardly, and is then not susceptible to deform on thicker direction, therefore prevent the torsiversion malposition of staple, guarantees
The B font that staple 1 is formed is in a plane.
The antimicrobial 3 contained in channel 2 is triclosan or flamazine or nano silver or sulphadiazine.Resist micro- life
Agent 3 also may include halogenated hydroxy ether, acyloxy diphenyl ether and their combination.Antimicrobial 3 is further selected from Austria and replaces
Buddhist nun's pyridine, PHMB, triclosan, copper, silver, gold, selenium, gallium, Taurolidine, 2- (chloro amido) ethanesulfonic acid, alcohol, LAE, MAPD, OAPD with
And their mixture.When 1 compressive deformation of staple, nail leg tip breakages, the staple 1 that triclosan is deformed squeezes injection and is kissed
It is combined and knits in 4, to reduce the possibility of postoperative infection.
1 material of staple is titanium, tantalum, magnesium alloy.
