Embodiment 1
Referring to Fig. 1 to Fig. 2, the operation anastomat of the embodiment of the present invention 1 is shown, it includes：Apparatus
Body 100, the handle portion 200 for being arranged on the near-end of body 100 and the ailhead for being arranged on the near-end of body 100
Portion 300.
Instrument body 100 includes thering is support 101 proximally and distally.Handle portion 200 is included by surgery
Gripping member 201 that doctor holds with a hand etc..
Nail head 300 includes nail bin groupware 1, anvil block 2 and tissue maintaining body (non-label).
Preferably, in the present embodiment, nail head 300 is bending, and operation anastomat is kissed for flexure type
Clutch, referring to Fig. 1 to Fig. 3, nail head 300 is included for supporting and installing nail bin groupware 1 and anvil block
2 U-shaped supporting construction 3.Nail head 300 can be designed to have many of replaceable nail bin groupware 1
Secondary percussion lock, it is also possible to be designed to single percussion lock.
Nail bin groupware 1 can be at one separately between position and the near position that connects relative to anvil block 2
Carry out relative motion.Operation anastomat shown in Fig. 1 is in opening, and nail bin groupware 1 is relative to anvil
Seat 2 is placed between nail bin groupware 1 and anvil block 2 in the position separately with by tissue.Fig. 2
Shown operation anastomat is in closure state, and nail bin groupware 1 is in described being close relative to anvil block 2
Position with by between the two tissue positioning and clamp.
Referring to Fig. 3, nail bin groupware 1 includes nail bin 11 and the cutting knife being movably disposed in nail bin 11
12.Anvil block 2 includes being arranged on the knife anvil 21 and nail anvil 22 of the distal end of nail bin 11, knife anvil 21 be provided with
The corresponding cutting packing ring 211 of cutting knife 12.
In the present embodiment, referring to Fig. 3, knife anvil 21 be located at nail anvil 22 distal end, and with nail anvil 22
It is removably secured connection.Nail anvil 22 is provided with nail forming area (not marked in figure) and opens up thereon
There is through hole (through hole may be located at the center of nail forming area).Therefore, when nail anvil 22 and knife anvil 21
During connection, through hole exposes cutting packing ring 211, and thus, anvil block 2 is in the proximal end face towards nail bin 11
The upper nail forming area that there is cutting packing ring 211 simultaneously and be centered around around cutting packing ring 211.
Cutting knife 12 stretches out and marches to cutting packing ring 211 in which can activated from nail bin 11.Specifically,
In the present embodiment, body 100 and handle portion 200 are designed to have and make nail bin 11 and the anvil block 2 can
Percussion with close mechanism (not shown) close to each other and for firing anastomosis staple and cutting knife 12
Mechanism's (not shown).As depicted in figs. 1 and 2, handle portion 200 include can pivot from body 100
The trigger 202 for extending out with turning.In the present embodiment, trigger 202 with close mechanism the phase in actuating
Association, while being also associated in actuating with firing lock.As shown in figure 1, nail bin 11 is in opening
Position is so as to tissue is placed between nail bin 11 and anvil block 2.When surgeon's grip pressure trigger 202, pull
Machine 202 is moved towards gripping member 201, so as to drive close mechanism so that nail bin 11 is moved towards anvil block 2.
As shown in Fig. 2 nail bin 11 is in the close position, nail bin face and the proximal end face of anvil block 2 of the distal end of nail bin 11
It is close to each other to position and keep so as to organize.Afterwards, when surgeon continues grip pressure trigger 202, hit
Hair mechanism releases cutting knife 12 and anastomosis staple from nail bin 11, shoots respectively to the cutting packing ring of anvil block 2
211 and nail forming area cutting and clench tissue.
In an alternate embodiment of the present invention, handle portion 200 include two triggers (closure trigger and
Firing trigger), it is associated in actuating with close mechanism and firing lock respectively.
Referring to Fig. 2 and Fig. 3, tissue maintaining body includes that cutting packing ring 211 can be maintained at by organizing
The first extension 14 and the second extension 212 between two ends.Specifically, at operation anastomat
When closure state shown in Fig. 2, tissue is clamped at the distal end nail bin of nail bin 11 in a thickness direction
Between the proximal end face of face and anvil block 2, the two ends of tissue are subject to the first extension 14 and the second extension 212
Constraint and holding, so as to by the two ends of tissue be maintained at cutting packing ring 211 two ends between so that group
Knitting will not spill into outside cutting packing ring 211 because of excessive compression, and thus cutting knife 12 can detachment completely
It is constrained on the tissue between cutting packing ring 211 two ends.
Wherein, referring to Fig. 2 and Fig. 3, the first extension 14 is arranged in nail bin 11, and it can be caused
Stretch dynamicly, so as to the retracted position with retraction nail bin 11 and extend out to stretching for anvil block 2 from nail bin 11
Out position.In the present embodiment, the first extension 14 is associated with above-mentioned close mechanism in actuating,
When trigger 202 drives close mechanism to cause that nail bin 11 is moved to closing position to anvil block 2, first extends
Part 14 extend out to anvil block 2 from nail bin 11.In an alternate embodiment of the present invention, first extends
Part 14 can also be manually mode activated.
Preferably, in the present embodiment, the first extension 14 is alignment pin, when alignment pin 14 extend out to
During anvil block 2, alignment pin 14 coordinates with anvil block 2 realizes position alignment.Preferably, in the present embodiment,
The position of a side on the alignment pin 14 and anvil block 2, positioned at cutting packing ring 211 coordinate realize it is right
It is accurate.Preferably, in the present embodiment, the alignment pin 14 can have the plunger of a point, on anvil block 2,
A side positioned at cutting packing ring 211 can be provided with a corresponding groove/opening (not shown), plunger
Coordinate with the slotted eye and realize being aligned.The align structures can realize the position alignment of nail bin 11 and anvil block 2,
Specifically, the nail forming area pair on the nail bin face and nail anvil 22 of the distal end of nail bin 11 on the one hand can be realized
Standard, prior one side is better achieved the position alignment of cutting knife 12 and cutting packing ring 211.
Referring to Fig. 3 and Fig. 4, the second extension 212 is fixedly installed on knife anvil 21 and from knife anvil 21
Extend to nail bin 11；The inner side contacted with tissue of the second extension 212 is provided with one along its length
Guiding structural 212C, stretches out from nail bin 11 in cutting knife 12 and marches to the process of cutting packing ring 211
In, the one end of cutting knife 12 slides into cutting packing ring 211 along guiding structural 212C.
Preferably, in the present embodiment, referring to Fig. 4, guiding structural 212C is a chute.The chute
The distal end of 212C is formed at the other end of cutting packing ring 211, so that cutting knife 12 is slided along chute 212C
Move to cutting packing ring 211, the position alignment of cutting knife 12 and cutting packing ring 211 is better achieved, with
It is completely cut off tissue.
Preferably, in the present embodiment, referring to Fig. 4, the second extension 212 is with knife anvil 21 integratedly
Shaping.
Preferably, in the present embodiment, referring to Fig. 4, the inner side that the second extension 212 is contacted with tissue is in
Existing raised line shape, the raised line is internally formed chute 212C.It is same with what is stopped into row constraint to organizing in raised line
When, the one end of cutting knife 12 is slided in the chute 212C inside raised line, using such structure,
During traveling, the blade of cutting knife end can cover the tissue that raised line is stopped to cutting knife, so that complete
Full detachment tissue, prevents the situation of tissue adhesion's (not completely cutting through).
It should be understood that, although the present specification is described in terms of embodiments, but not each implementation method
An independent technical scheme is only included, this narrating mode of specification is only for clarity, originally
Art personnel should be using specification an as entirety, and the technical scheme in each implementation method can also
