Split or deform), the nail bin that now the nail bin die trial 11 can be replaced by into corresponding color is installed on regular jaw 12 again to tissue
Carry out suture operation;If tissue thickness is blocked up, fed back on moving jaw 10 due to larger reaction force caused by tissue and
Moving jaw 10 is made up of compression feedback material, then now can judge the choosing of nail bin by the feedback change of moving jaw 10
Select, be fragile material (such as the material such as cast iron, ceramics, in the case where stretching or the external force effect such as impacting in feedback material referring to Fig. 6
Fracture will be destroyed by only producing the deformation of very little) in the case of, the larger reaction force acted on moving jaw 10 can make work
Movable clamp port 10 is broken (as shown in the A in Fig. 6), extracts the servicing unit of the stapler out from patient's body, and operator passes through meat
Eye can observes that the compression feedback of moving jaw 10 (is broken) situation, then may determine that and nail bin die trial used herein
Nail bin is not suitable for corresponding to 11, then the nail bin die trial 11 again from other sizes re-starts assessment;Further, lived in manufacture
In the case that the feedback material of movable clamp port 10 is the material (for example, rubber) of flexible aftereffect property, due to by thicker
In the case of the reaction force of tissue, moving jaw 10 deforms, and after servicing unit is extracted out from patient's body, moving jaw 10
Deformation will not recover immediately but need a period of time after could gradually restore to the original state, thus selection have enough recover when
Between elastic after effect material (e.g., deformation recovery time is in the range of 0.5s-600s) carry out creative activity jaw 10, then from patient's body
Whether the nail bin that doctor has enough time to observe the situation of moving jaw 10 to judge to estimate after the interior device for taking out deformation closes
Fit so as to the nail bin die trial 11 for deciding whether more to renew;Further, feedback material be plastic material (for example, it may be steel,
The plastic deformation such as copper, aluminium alloy material or nonmetallic plastic material) in the case of, the grip tissue number of jaw 10 and 12
After second, moving jaw 10 is opened, servicing unit is taken out, is then closed again moving jaw, attempts with corresponding with nail bin die trial 11
The gap location that inserts between moving jaw 10 and regular jaw 12 of thick plates 15, if thick plates 15 can not insert gap,
Illustrate that nail bin corresponding to the nail bin die trial 11 meets the condition for suturing the thickness tissue, then the now nail bin of replaceable respective color
Actual suture is carried out to tissue, if moving jaw 10 deforms larger, thick plates 15 may be inserted into gap, then illustrates the tissue too
Thickness, and the 11 corresponding nail bin of nail bin die trial is improper is used for the tissue, now needs to change the nail bin die trial 11 of other sizes
Again tissue thickness is assessed.It is used for the servicing unit of stapler by using this, can precisely judges before actual operation
It is adapted to the nail bin of tissue thickness, the medical-risk being directly likely to occur with nail bin suture tissue is avoided, such as in the nail bin of selection
Staple height it is inadequate, so as to can not well suture tissue even result in oozing of blood or previous anastomotic cracking etc..According to the present invention's
Another embodiment, above-mentioned moving jaw 10 are rigid material, nail bin die trial 11 by fragile material or elastic after effect material or
Plastic material manufactures, and corresponding nail bin by rigid material, can also reach same assessment effect respectively with nail bin die trial 11

Spacer 13 is caused to continue to be promoted and deformed by force when moving to distalmost end in its stroke groove, but in the implementation of the present invention
In example, connected between push pedal 2 and pressing plate 6 by spring 3, because the maximum compressibility of spring 3 is more than the range of trigger shaft 18
Amount, so when spacer 13 is pulled to its stroke groove distalmost end (now spacer 13 is propped up by stroke groove edge), it is excessive
Percussion force can be only applied on spring 3, and spring 3 is compressed in compressible scope, will not promote pressing plate 6 by force and will not be by force
Spacer 13 is promoted to continue to move, so as to avoid the parts such as pushing meanss from being destroyed, or even when organizing very thick, spacer 13 is also
Do not move to its stroke groove distalmost end to be just stuck, now excessive motive force still can be applied on spring 3, will not be by force
Pressing plate 6 and spacer 13 are promoted, so as to avoid tissue by excessive compression so that impaired.After percussion, reset button is pulled
