120 are aligned always with nail anvil plate 301 upper groove.
Pushing needle bar 200 pushes lock 122 when moving forward to maximum position, the annular convex rib 1221 on lock 122 by
The annular groove 1241 of 124 inner wall of color chips can be embedded in after external force.Nail pushing plate 127 travels forward during percussion, due to color chips 124
Being stopped by the third boss 1252 on 125 inner wall of cartridge, the movement of color chips 124 is limited by third boss 1252, because
This nail pushing plate 127 is detached with color chips 124.At this point, indicating window 1251 is it is shown that be still the color of color chips 124.
Fig. 1 is referred to, after the completion of percussion, retracts tissue pilot pin 123, lock 122 takes back color chips 124, at this time color chips
124 indicating window 1251 on the second position not being revealed in indicating window 1251, cartridge 125 will show color chips 124
Outer color.Show that above-mentioned linear incision anastomat nail storehouse had fired, user's prompt can be given, it is ensured that next time, percussion made
With new nail bin, the efficiency of operation is improved.
In addition, trigger shaft can take back nail pushing plate 127 and blade 128 together when percussion resets, to prevent from being missed by blade 128
Wound.
The present invention also provides a kind of linear incision staplers, including above-mentioned linear incision anastomat nail storehouse component.It can
Give user's prompt, it is ensured that next time, percussion used new nail bin, improved the efficiency of operation.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
