Please cooperate and consult shown in Figure 8ly, a kind of anastomat of the present invention comprises nail supporting base assembly 1, nail bin groupware 2, propulsion plant 3, actuating device 4, fixed handle 6, flexible handle 7, adjusting device 8 and state indicating device of the present invention 5.For convenience's sake, will be called near-end near operator's a side (right side shown in promptly scheming, a side at adjusting device place) in the following description, will be called far-end away from operator's a side (on the left of promptly shown in the figure, a side at nail supporting base assembly place).
Wherein, nail supporting base assembly 1 links to each other with actuating device 4 at near-end, and actuating device 4 flexibly connects with adjusting device 8, and propulsion plant 3 extends in sleeve pipe and fixed handle 6, and propulsion plant 3 also links to each other with flexible handle 7.State indicating device 5 is installed in the fixed handle 6, is positioned at a side of actuating device 4, and can observe the state that apparatus is closed and pull the trigger through the convex lens 56 that is installed in fixed handle 6 surfaces.
Specifically, the indicating dial 51 and the convex lens 56 of state indicating device 5 are fixedly mounted on the fixed handle 6, closed pulling-on piece 54 and percussion pulling-on piece 55 mobilizable being installed in the fixed handle 6.The closed pulling-on piece 54 of state indicating device 5 slips groove 542 through actuating device and is slidingly connected with actuating device 4; The percussion pulling-on piece 55 of state indicating device 5 slips groove 553 through propulsion plant and is slidingly connected with propulsion plant 3, between the spring mounting structure 543,552 of state indicating device 5 and the fixed handle 6 back-moving spring is installed all.
Preferable; Please cooperate consult shown in Figure 9; Actuating device 4 of the present invention also comprises gap regulating block 41, and gap regulating block 41 is sleeved on the drive lead screw of actuating device 4 through groove 411, and a side is provided with protruding 412; This convexity 412 is slipped in the groove 542 at actuating device and is slided, thereby realizes being slidingly connected of actuating device and closed pulling-on piece 54.
During installation: at first indicating dial 51 is fixedly installed on the fixed handle 6.The rotating shaft 532 of percussion contiguous block 53 is inserted in the rotating shaft inner chamber 523 of closed contiguous block 52, and closed contiguous block 52 can relatively rotate with percussion contiguous block 53.To cooperate contiguous block 52,53 upper ends of installing to insert the centre bore 511 of indicating dial 51 then, more closed pointer 58 and percussion pointer 57 will be installed on the corresponding pointer installation base 524 and 533.Closed pulling-on piece 54 and percussion pulling-on piece 55 are installed at last.
Below with closed indicating area respectively with red, yellow, green non-closure (initially) state, transitive state, the closure state represented; The percussion indicating area representes that with red, yellow, green non-percussion (initially) state, transitive state, percussion completion status are example respectively, and concrete operations step of the present invention is described.
Please cooperate and consult shown in Figure 10ly, before the instrumentation, closed pointer 58 points to red areas, is original state.The rotation adjusting nut makes the axis of guide of actuating device 4 expose fully, pulls up nail supporting base assembly 1; Its implantation is accomplished fluently in the end tissue of pocket; Stapler main body gets into other end tissue, and the jump ring pipe on the nail supporting base assembly 1 is connected rotation adjustment device with actuating device 4 then; Make the drive lead screw and the connected axis of guide drive nail supporting base assembly 1 and draw close to have certain clearance until nail supporting base assembly 1 and nail bin groupware 2 towards nail bin groupware 2 one sides.
In this process; Screw mandrel that actuating device 4 is comprised and the gap regulating block 41 that is fixed on the screw mandrel move to adjusting device 8 ends; Set convexity 412 set actuating device on closed pulling-on piece 54 slips in the groove 542 and slides to indicating dial one end far away by nearly indicating dial 51 1 ends on the gap regulating block 41, slips groove 542 other ends until the actuating device with closed pulling-on piece 54 and offsets, in this process; Closed pulling-on piece 54 does not stress, and closed pointer 58 is positioned at red area always.
Please cooperate and consult shown in Figure 11ly, the adjusting nut of further screwing, screw mandrel drive gap regulating block 41 and move to fixed handle 6 afterbodys; The closed pulling-on piece 54 of gap regulating block 41 pullings moves to fixed handle 6 afterbodys; Closed pulling-on piece 54 drives closed pointer 58 through closed contiguous block 52, arrives yellow area by red area, and yellow area is the safe transition zone; Remind user, apparatus is about to closed.The rotation adjusting nut, the limited block in drive lead screw and anastomat fixed handle offsets, and closed pointer 58 points to green area, but the expression apparatus arrives the lock time, the closed completion.
Behind the tissue closure; Open insurance; Fastening flexible handle 7 is pulled the trigger, and flexible handle 7 promotes propulsion plants 3 and advances forward, and propulsion plant 3 slips in the groove 553 to the slip of advancing of anastomat near-end at percussion pulling-on piece 555 propulsion plants through its fixture block that is provided with 31; Percussion pulling-on piece 55 does not stress, and percussion pointer 57 indicating areas are red.
Please cooperate consult shown in Figure 12; The flexible handle 7 of further holding with a firm grip, propulsion plant 3 drives percussion pulling-on pieces 55 and moves to the anastomat near-end, and drives percussion pointers 57 through percussion contiguous block 53 and rotate; Arrive yellow area by red area; Remind user, apparatus inseam nail is about to pulled the trigger, and endless knife is about to cut off tissue.Flexible handle 7 is held on earth, and anastomosis staple passes tissue and gets into the nail Slot shaping, and endless knife will organize with knife washer and cut off together, and the generation sense that falls through is pulled the trigger pointer 57 simultaneously and reached green area by yellow area.At this moment, closed pointer 58 is positioned at green area simultaneously with percussion pointer 57, and coincideing of luminal organs accomplished in expression, and operation is accomplished smoothly.
When resetting, unclamp flexible handle 7, and the nail supporting base assembly 1 of outwarding winding, nail supporting base assembly 1 is withdrawn from human body with anastomat, and closed pointer 58 resets under the effect of the closed pulling-on piece 54 and the back-moving spring of percussion pulling-on piece 55 with percussion pointer 57, points to red area again.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection scope of the present invention.
