It is preferably carried out mode.
Specific embodiment
Fig. 1 to Figure 14 is refer to, the invention provides a kind of perforator with automatic sewing function, including：Nail bin 1, bag
Include first position and the second position；Nail forming blocks 2, are connected with nail bin 1；Slide block 3, including the 3rd position and the 4th position；First
Flexible member 4, to nail bin 1 First Driving Force is applied；Second flexible member 5, to slide block 3 the second driving force is applied；Puncturing lever 6,
Nail bin 1 is resisted against in the first direction the first side of puncturing lever 6 when being located at first position, along second when slide block 3 is located at three positions
Direction is resisted against the second side of puncturing lever 6；Puncturing lever 6 is extracted to nail bin during the first firing position 1 first in the first flexible member 4
In the presence of move to the second position, slide block 3 moves in the presence of the second flexible member 5 when puncturing lever 6 is extracted completely
Forming blocks 2 are followed closely by the molding of suturing nail 7 in nail bin 1 in four positions to drive.Preferably, first direction is orthogonal with second direction.
When using, Fig. 8 and Fig. 9 is refer to, when puncturing lever 6 runs through nail bin 1, nail forming blocks 2 are in the first flexible member 4
It is resisted against under effect on puncturing lever 6, meanwhile, slide block 3 is resisted against on puncturing lever 6 in the presence of the second flexible member 5.Refer to
Figure 10 and Figure 11, when puncturing lever 6 is extracted upwards to the first firing position for illustrating, puncturing lever 6 is vacateed for nail forming blocks 2
Mobile space, then, in the presence of the first flexible member 4, puncturing lever is released by first position and be covered in nail forming blocks 2
6 lower section (reaching the second position), but, because the position of slide block 3 is higher than the position for following closely forming blocks 2, therefore, slide block 3 is still
So it is subject to the obstruction of puncturing lever 6 and keeps original state constant (being still located on the 3rd position).Figure 12 and Figure 13 is refer to, when
Continue up after puncturing lever 6 is extracted completely, puncturing lever 6 vacates mobile space for slide block 3, then, in the second flexible member 5
Under effect, direction movement of the slide block 3 from the 3rd position to nail forming blocks 2, and nail forming blocks 2 are depressed to the direction of nail bin 1, directly
To the 4th position, so that the suturing nail 7 in nail bin 1 is pushed out aftershaping, the tissue on otch both sides is drawn in suture, reach automatically
Suture purpose.
It can be seen that, as a result of above-mentioned technical proposal, after the completion of Minimally Invasive Surgery, puncturing lever 6 is being extracted from intraperitoneal
While, it is possible to achieve the automatic sewing of otch, so as to reduce operation operation, operating time is saved, with simple structure, operation
Conveniently, the characteristics of low cost.
Preferably, it is formed with first in nail forming blocks 2 and pushes inclined-plane 8, is formed with slide block 3 for pushing tiltedly by first
Apply the second of lower pressure towards nail forming blocks 2 and push inclined-plane 9.It is to stagger to set in vertical direction with slide block 3 due to following closely forming blocks 2
Put, therefore, when slide block 3 is moved to the direction of nail forming blocks 2, it second pushes inclined-plane 9 and follows closely first pushing for forming blocks 2
Inclined-plane 8 is contacted, and with the further movement of slide block 3, moves down nail forming blocks 2, so as to the suturing nail being placed in nail bin 1
7 release and molding.
Preferably, the perforator with automatic sewing function is also included to nail block 10, at least a portion activity of nail block 10
Ground insertion nail bin 1 bottom in nail block installing hole.Preferably, it is L-shaped to nail block 10.Figure 12 is refer to, during molding, suturing nail
7 two tack claws are embraced to nail block 10.Figure 14 is refer to, after 7 molding of suturing nail, operator will be to nail block 10 to away from nail
The direction movement in storehouse 1, so as to remove from the suturing nail 7 for being formed to nail block 10.
Preferably, nail bin 1 sets towards the depressed part that U-shaped is provided with to the side of nail block 10 to the nail correspondence depressed part of block 10
Put.Can be to provide certain installing space to nail block 10, so as to reduce the volume of the present invention using depressed part.
Preferably, in one embodiment, the first flexible member 4 and it is arranged at the same side of nail bin 1 to nail block 10.When
When first flexible member 4 promotes nail bin 1 to move, also promote and moved together with nail bin 1 to nail block 10.
Preferably, the both sides to nail block 10 are respectively arranged with first flexible member 4.Preferably, nail bin 1 is T-shaped,
Nail bin 1 each side has one for fixing the blind hole of the first flexible member 4.Using two the first flexible members 4, can be with
More smoothly promote nail bin 1 so as to which motion is more smooth, and stuck problem will not occur.
Preferably, the number of the second flexible member 5 is one.It is obvious also possible to it is elastic to be arranged as required to multiple second
Element 5, belongs to the equivalent mode of this patent, within the protection domain of this patent.
Preferably, the perforator with automatic sewing function also includes housing 11, and housing 11 has been internally formed installing space, shell
The through hole 12 being provided through on body 11, nail bin 1, nail forming blocks 2, slide block 3, the first flexible member 4 and the second flexible member 5 are equal
It is arranged in installing space, puncturing lever 6 passes through through hole.Especially, it is provided with the inwall of the installing space of housing 11 for solid
The blind hole of fixed first flexible member 4 and the second flexible member 5.During installation, the one of the first flexible member 4 and the second flexible member 5
End be placed in the blind hole of housing 11, the other end be placed in nail bin 1 or slide block 3 on corresponding blind hole in, with realize it is elastic to first
The fixation of the flexible member 5 of element 4 and second.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
