The distal end 231 of the fixed chopping block gasket；Second flexible fastening piece 240 can be gasket spring, elastic piece, cylinder spring or torsion
The structure that spring etc. can be analyzed to independent energy-storaging spring and be pressed, and under suitable installation site and operating condition, it is described
First flexible fastening piece 140 can be replaced mutually with second flexible fastening piece 240.In one embodiment, described second
Flexible fastening piece 240 can be metal material, such as copper, aluminium are made, and can also be made of plastic material, such as thermoplastic elastomer (TPE)
TPE, acryl plastics PMMA etc., making second flexible fastening piece 240 using flexible energy-accumulation material can protect
Card reliably fastens the distal end 231 of the chopping block gasket, and can be described by making in the end that the cutter 310 move
Deformation occurs and discharges the distal end 131 of the chopping block gasket for energy storage flexible fastening piece, not only securely and reliably, and it is easy to operate.
In one embodiment, second flexible fastening piece 240 is gasket spring comprising pressure force arm 241 and company
Connect end 242, wherein the connecting pin 242 is connected on the chopping block shell 210, and the pressure force arm 241 connects the connection
End 242 and the distal end 231 for being used to fix the chopping block gasket.Specifically, the connecting pin 242 by welding, riveting, bonding or
The mode of buckle is fixed on the chopping block shell 210；In one embodiment, the connecting pin 242 is solid by welding
It is scheduled on the chopping block shell 210, the connecting pin 242 stronger can be fixed on the chopping block shell by the mode of welding
210, the pressure force arm 241 by external force deformation occurs when, can be avoided caused by the connecting pin 242 is not fixed firmly
The distal end 231 of the chopping block gasket cannot reliably discharge bring security risk.
Figure 18-Figure 20 is please referred to, Figure 18 is the enlarged view of 200 distal end of chopping block component shown in Fig. 1；Figure 19 is Fig. 1
Shown in 200 proximal end of chopping block component enlarged view；Figure 20 is the signal that deformation occurs of chopping block gasket 230 shown in Fig. 2
Figure.During the cutter 310 movement, when the cutter 310 are moved to the proximal end of the chopping block component 200,
The cutting edge oral area 312 is cut since the chopping block gasket auxiliary incision 234, after the chopping block fixation hole 233
Continue to cut the chopping block gasket auxiliary cutting line 232, in above-mentioned cutting process, the proximal end of the chopping block gasket 230 occurs
Deformation and it is mobile to two sides, and then fall off from the fixed pin 250 to discharge the proximal end of the chopping block gasket 230.When described
When cutter 310 move to the distal end of the nail bin groupware 200, the front end protrusion in the upper knife body portion 311 moves partially into institute
It states at the second flexible fastening piece 240, the front end protrusion part in the upper knife body portion 311 compresses second flexible fastening piece 240
The pressure force arm 241, to force the pressure force arm 241, deformation occurs and leaves the initial position (void in Figure 20
Line position) 210 directions of Xiang Suoshu chopping block shell are mobile, and its own is in line shape by the L deformation of initial position, and then by the chopping block
The distal end 131 of gasket discharges.
In conclusion the distal end of chopping block gasket described in the utility model 230 and the distal end of the nail bin gasket 130 difference
Be inserted into fastening in the chopping block slot 223 and the nail bin slot 123, make the chopping block gasket distal end 231 and the nail bin
The distal end 131 of gasket, which avoids to scratch with tissue, causes the risk of flange, and can be according to the fortune of stapler jaw contacts tissue
Dynamic direction greatly reduces after jaw folder closes naturally along exhibition and the risk of fold occurs, further improve the chopping block gasket
230 and the nail bin gasket 130 and tissue identical quality.Meanwhile the chopping block gasket 230 and the nail bin gasket 130
The tissue contact surface of appearance profile shape and size and the attached nail bin casket 120 and the chopping block body 220 is similar and omits
It is small, avoid in use occur gasket edge with tissue occur it is unnecessary contact, make the risk of fold or movement.In addition, our
The elastic element (the first flexible fastening piece 140 and the second flexible fastening piece 240) that presses in case is all made of medical stainless steel material,
The connection type of itself and the nail bin casket 120 and the chopping block shell 210 does not also increase additional materials, therefore filters out there is no bad
Biological safety risk caused by object.
Positioning is realized by the mode of pressing in the chopping block gasket distal end 231 and the distal end 131 of the nail bin gasket, due to closing
Force arm configuration (the force arm 141 and the second flexible fastening piece of the first flexible fastening piece 140 of elastic element is pressed in reason design
240 force arm 241) so that the chopping block gasket 230 and the nail bin gasket 130 obtain suitable precompression, and it is coincideing
Not to described tight in the multiplicating clamping of device jaw (nail bin groupware 100 and the chopping block component 200) and homing action
The precompression of compression elasticity element has an impact, it is ensured that the chopping block gasket 230 described in this action process and the nail bin gasket
130 reliable location.
Meanwhile the chopping block gasket distal end 231 and the distal end 131 of the nail bin gasket are fixed with release movement by same unitary
Part is implemented, and intermediate transmission link is reduced, and simplifies linkage release process, and compressed position for elastic element force arm
It sets and has carried out rational Design on Plane, making force side is laborsaving lever, significantly reduces the direct active force of user, improves system
Ergonomic, release movement more rapidly, it is laborsaving, reliability is higher.
On the other hand, it since the resist-nailed seat 260 is not resetted with the cutter 310, will be stayed in after completing percussion
120 distal end of nail bin casket, remains compressing to 140 force arm 141 of the first flexible fastening piece；And second bullet
Property fixing piece 240 force arm 241 since the front end protrusion part in the upper knife body portions 311 of the cutter 310 compresses production
Raw plastic deformation, cannot freely reset, to realize after the reset of cutter 310 is completed in percussion, the chopping block gasket
230 and the nail bin gasket 130 completely release.
In addition, the elastic element that presses in the present embodiment is positioning and is discharging the chopping block gasket 230 and the nail bin pad
Any change is not caused to stapler outer dimension in the motion process of piece 130, there is no part-structures and tissue to connect
Touching causes the safety in utilization hidden danger of secondary injury.The chopping block gasket 230 and the nail bin gasket 130 have been passed through using preceding
Press elastic member and be fixed on stapler jaw corresponding position, user only need to be according to the application method of existing standards device
Effective use to this programme instrument is completed, does not need additional operation sequence, study needed for reducing new accessories use
It is time, convenient to use；The present embodiment largely borrows existing standards device components, and technical maturity, stabilization are increased
Gasket fastening system component structural is simple, assembly is convenient, can be mass-produced in a manner of conventional machining, system is overall
Technology difficulty is lower, and manufacturing cost is cheap.
The foregoing is merely the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
It is equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, directly or indirectly uses
In other related technical areas, it is also included in the patent protection scope of the utility model.
