Further, refer to Fig. 4 and Fig. 5, when after nail bin 2 is installed on nail bin frame 1 and before nail-head component percussion, cutting knife 5 is positioned at primary importance, unlocking feature (i.e. projection 32) the transverse shear stress safety block 61 of the percussion block 3 being positioned at nail bin 2 near-end is located at described 3rd position, safety block 61 is subject to the backstop of projection 32 and then makes elastomeric element (i.e. bullet block 62) be in compressive state, now, promote push broach bar 4 that cutting knife 5 and percussion block 3 can be driven to move to far-end, in order to tissue is cut and sews up.
Further, please also refer to Fig. 6 to Fig. 9.
Fig. 6 and Fig. 7 respectively illustrates the structural representation in the cross section of A-A and the B-B when nail-head component in Fig. 3 fires.As shown in Figure 6 and Figure 7, after cutting knife 5 promotes percussion block 3 under push broach bar 4 acts on, percussion block 3 is moved out safety block 61 along the first stopper slot 13 to the far-end 12 of nail bin frame 1.In the process, cutting knife 5 is moved to the second position by primary importance, safety block 61 is removed due to the unlocking feature (i.e. projection 32) on percussion block 3 and is lost transverse shear stress, and then move to the 4th position (safety block 61 of such as both sides closes, and gap is less than the transverse gage of cutting knife 5) under the elastic force effect of elastomeric element (bullet block 62).The position at cutting knife 5 place shown in Fig. 7 is the second position.Meanwhile, the position of the safety block 61 shown in Fig. 6 and Fig. 7 is the 4th position.As it is shown in fig. 7, when safety block 61 is positioned at four positions, partial insurance block 61 stretches into the first stopper slot 13, between the primary importance and the second position of cutting knife 5.
Further, owing to, in the preferred embodiments of the present invention, described nail-head component includes the Liang Ge insurance institution being arranged at the first stopper slot 13 both sides.Therefore, in this embodiment, safety block 61 is positioned at the 4th position and refers to that two safety blocks 61 are respectively positioned on the 4th position, and namely the part-structure of two safety blocks 61 stretches into the first stopper slot 13 and between described primary importance and the second position.As shown in Figure 6, when two safety blocks 61 are respectively positioned on four positions, the transverse gage being smaller than cutting knife 5 between two safety blocks 61.
Preferably, the transverse gage of cutting knife 5, less than or equal to the transverse gage of projection 32 of percussion block 3, is more beneficial for after the projection 32 firing block 3 is removed, and cutting knife 5 can be moved by the 3rd position at safety block 61 and be moved to the second position by primary importance before the 4th position.
Further, after completing the cutting to tissue, sewing up, cutting knife 5 need to carry out the primary importance returned before firing that resets, and percussion block 3 rests on the far-end of nail bin.Fig. 8 a and Fig. 8 b illustrates the structural representation of the section B-B after nail-head component percussion in cutting knife reseting procedure, and Fig. 8 b is the close-up schematic view at the D place of Fig. 8 a.As shown in figs. 8 a and 8b, safety block 61 has one first guide portion, and the first guide portion is for when cutting knife 5 is moved to primary importance by the second position, guiding safety block 61 to be moved to the 3rd locality by the 4th position.In Fig. 8 b illustrated embodiment, described first guide portion is one first inclined-plane 611, first inclined-plane 611 is positioned at the far-end of safety block 61, first inclined-plane 611 tilts from being distally-oriented to the first stopper slot 13 direction convex type, the such as cross section of safety block 61 is trapezoidal, extends to the safety block 61 one side near the first stopper slot 13 with the far-end of safety block 61 for starting point.When the remote location that cutting knife 5 is moved to safety block 61 to primary importance direction by the second position, cutting knife 5 promotes the first inclined-plane 611, the component along the second stopper slot 14 direction that first inclined-plane 611 produces makes safety block 61 move to the 3rd locality, and elastomeric element (i.e. bullet block 62) is again at compressive state.When safety block 61 is fully located at the both sides of cutting knife 5, safety block 61 is in the 5th position.It is understood that the transverse gage of cutting knife 5 is less than or equal to the transverse gage of the projection 32 of percussion block 3, therefore, the 5th position is between the 3rd position and the 4th position.When the transverse gage of cutting knife 5 is identical with the transverse gage of the projection 32 of percussion block 3, the 5th position and the 3rd position are same position.
Further, it is preferable that the near-end 51 of cutting knife 5 can also have the second guide portion, described second guide portion coordinates the first guide portion, guides safety block 61 to be moved to the 3rd locality by the 4th position.Described second guide portion can be the second inclined-plane adapted with the first inclined-plane 611.Described second inclined-plane is correspondingly arranged at the both sides of the near-end 51 of cutting knife 5.The setting on the second inclined-plane is more beneficial for the near-end 51 transverse shear stress safety block 61 of cutting knife 5 and moves to the 3rd position.
Fig. 9 illustrates the structural representation of the section B-B after cutting knife reset.As shown in Figure 9, it is back in the process of primary importance at cutting knife 5, when cutting knife 5 moves to after no longer produce the position of interaction force with safety block 61, the transverse shear stress of cutting knife 5 is lost between two pieces of safety blocks 61, under the elastic force effect of elastomeric element (bullet block 62), it is moved again to the 4th position, is barred between described primary importance and the second position.Due to the transverse gage being smaller than cutting knife 5 between two safety blocks 61; and the near-end of safety block 61 does not have guide portion; therefore; if carrying out secondary percussion; safety block 61 can stop that cutting knife 5 is moved to the second position by primary importance; make apparatus cannot be carried out secondary percussion, just can normally fire after the nail bin only more renewed.And when the nail bin more renewed, the projection 32 of the percussion block of new nail bin can be clamp-oned between two pieces of safety blocks 61 above through the guiding on the 3rd inclined-plane 612 from the spacing between two pieces of safety blocks 61, force safety block 61 to again return to the 3rd position simultaneously, be namely back to state as shown in Figure 5.Therefore, if the nail bin more not renewed 2, safety block 61 cannot be entered the second stopper slot 14 by transverse shear stress, then cutting knife 5 is stopped by safety block 61, cannot again move to the second position, thus playing the effect preventing nail-head component from carrying out secondary percussion when not changing nail bin.
The anti-secondary fire design of the present embodiment is mainly by being respectively arranged at the elastomeric element (bullet block 62) of the first stopper slot 13 both sides active force to safety block 61, after safety block 61 loses unlocking feature (projection 32) transverse shear stress of percussion block 3, the safety block 61 of both sides is close to each other, thus the percussion again after stoping cutting knife 5 to be pulled.
It will be appreciated by those skilled in the art that in the change case of the present invention, nail-head component can also play, by a described insurance institution, the effect preventing secondary from firing.In this change case, the side of the first stopper slot 13 arranges second stopper slot 14, insurance institution is arranged in the second stopper slot 14, when safety block 61 is positioned at four positions, safety block 61 stretches out in the second stopper slot 14 to the inwall direction of the corresponding side of the first stopper slot 13, and the part stretched out of safety block 61 is positioned at cutting knife 5 and moves on the mobile route of the second position from primary importance, thus limiting the cutting knife 5 movement to far-end, now, one described insurance institution is equally possible plays the effect preventing secondary from firing, and does not repeat them here.
The present invention also provides for a kind of chamber mirror surgical operation seaming and cutting device.This seaming and cutting device includes body and nail-head component.Wherein, body includes housing and the firing handle being located in housing, and nail-head component is the nail-head component shown in Fig. 1 to Fig. 9.Connecting tube 7 and the push broach bar 4 of nail-head component are connected with body.Firing handle can promote push broach bar 4, makes cutting knife 5 move to far-end 12 direction of nail bin frame 1.
