Fig. 1 is the structural schematic diagram of nail bin groupware in the prior art, and Fig. 2 is the nail bin frame peace of nail bin groupware in the prior art
The structural schematic diagram of binding storehouse side, as depicted in figs. 1 and 2, nail bin groupware includes: nail anvil 1 and nail bin frame 2 in the prior art,
The two sides of 11 end of nail anvil ontology are with the first side wall 12 and second sidewall 13 extended towards nail bin frame 2, the end of nail bin frame 2
It is attached between the first side wall 12, second sidewall 13 by pin 3, so that nail bin frame 2 is rotated by pin 3 around nail anvil 1,
So that shape is at a certain angle between nail anvil 1 and nail bin frame 2.
It has been found that when forming angle between nail anvil 1 and nail bin frame 2, the upper end of the first side wall 12, second sidewall 13
It needs to engage with the lower end surface of nail bin frame 2 at the one end of face far from pin 3, to avoid the first side wall 12, second sidewall 13
The one end of upper surface far from pin 3 at there is gap between the lower end surface of nail bin frame 2, once there is gap, work as nail bin
When component is in open configuration clamping tissue, the edge of tissue may can be snapped onto above-mentioned gap.If need at this time by
Nail bin groupware closure, if the tissue being caught in gap is less, then during being closed by force, the first side wall 12, second side
Tissue will be cut bad with the lower end surface of nail bin frame 2 at the one end of the upper surface of wall 13 far from pin 3 or crushed；If being caught in gap
Tissue it is more thicker, then nail bin groupware can not be just closed at all, the doctor used must re-operate and press from both sides to tissue
It holds, causes the inconvenience of user in this way.Therefore, in existing above structure, in order to enable the first side wall 12, second sidewall
13 upper surface is not in that gap, nail anvil 1 and nail bin frame 2 are being opened between the lower end surface of nail bin frame 2 at one end far from pin 3
Angle under open state between the two can only achieve 15 degree or so.
Since nail anvil 1 and angle of the nail bin frame 2 under open configuration between the two are smaller, the doctor used under small angles
It is not easy that folder will be organized between nail anvil 1 and nail bin 23, therefore, it is necessary to open configurations between further expansion nail anvil 1 and nail bin frame 2
Subtended angle, and after subtended angle expands, the first side wall 12, second sidewall 13 upper surface far from one end of pin 3 with nail bin frame 2
It must be not in gap between lower end surface.While applicant further found that, as shown in Figure 1, if by the end of nail bin frame 2 and first
The position of the pin 3 of connection between side wall 12, second sidewall 13 is moved to the left, then can be directly in the first side wall 12, second
Do not occur expanding nail anvil 1 under the premise of gap between the lower end surface of nail bin frame 2 at the one end of the upper surface of side wall 13 far from pin 3
The subtended angle of open configuration between nail bin frame 2.But above scheme is influenced by objective factor, and cannot achieve.
Concrete reason is as follows, and the specification of nail used in current global stapler is substantially unification, on nail bin 23
The overall length of nail position is also fixed, only tri- kinds of specifications of 30mm, 45mm, 60mm, for security consideration, right end on nail bin 23
The position of nail must be over the left end of the first side wall 12, second sidewall 13 because by nail on nail bin 23 to the tissue of cutting into
When row suture, the end of suture must be over the end of clamped cutting tissue, so guarantees the validity of suture, prevents from cutting
The case where end of disconnected tissue does not suture sufficiently and is likely to occur disengagement.Lead to that the first side wall 12, second sidewall 13 should be made in this way
Between inside at must retain about 1 half nail distance, enable cutter cut tissue sutured completely.Above situation causes
The position of the nail of right end must be over the left end of the first side wall 12, second sidewall 13 on nail bin 23, and be more than the first side wall 12, the
The distance of the left end of two side walls 13 will reach the one and half wide distances of nail at least, in this way, cause pin 3 position can not further to
It moves left, one and half nails must also be arranged in the space between the first side wall 12 and second sidewall 13 of nail anvil 1, and also need to stay to cut
The space that cutter enters.In conclusion existing nail bin groupware is by the left end of pin 3 and the first side wall 12, second sidewall 13
Distance accomplish close to minimum, under the premise of such, nail anvil 1 and angle of the nail bin frame 2 under open configuration between the two
Just reach 15 degree or so.Therefore, by the position of the pin 3 of connection between the end of nail bin frame 2 and the first side wall 12, second sidewall 13
Set this mode being moved to the left is influenced cannot achieve by nail bin groupware self structure.
For above situation, in order to effectively expand the subtended angle between nail anvil 1 and nail bin frame 2 under open configuration, Shen
