On the connecting column 294 of staple ontology.The conducting wire for guiding the direction of motion of suture 30 is additionally provided in described sleeve pipe inner casing 24
Frame 31.Staple and suture are made of absorbable material, as the illustratively Medical absorbables resinous wood such as optional polyglycolide
Material.Runner 22 and wind spring 23 cooperate in the suturing mechanism, when suture 30 is pulled out, due to the elastic force of wind spring 23, by suture
30 automatically retract；When wind spring 23 is shunk, drives runner 22 to rotate, while suture 30 being wrapped on runner 22, thus protect
Having demonstrate,proved forward line 30 can automatically retract.
Figure 19 shows the status diagram being installed to puncture awl component in puncture cannula component.
The laparoscope of the present embodiment punctures the operating process of the operating process of stitching unstrument as shown in figs 20 and 21, it may include with
Lower step:
Step 1: puncture awl component is inserted into puncture cannula component.
Step 2: using standard surgical, cut one and be enough to import the skin incision for puncturing stitching unstrument.
Step 3: being imported by skin incision and puncture stitching unstrument, when importing for the first time, the flat head shapes of puncture needle and skin are cut
Mouth direction is consistent, and puncture needle is only passed through human abdominal cavity tissue.
Step 4: fixed to puncture stitching unstrument vertical skin after importing for the first time.Release button is pressed, so that button pop-up solution
Except the pressing force between release button and the ejector pin handle, to extract ejector pin handle and to extreme higher position, direction turning piece at this time
It is flicked under the action of torsional spring, then depresses ejector pin handle, the direction turning piece can be pressed by ejector pin handle in ejector pin mechanism
Under the action of by staple pass through human body fascia tissue.
Step 5: will slowly puncture stitching unstrument and be inserted into abdominal cavity, so that puncture cannula exposes fascia surface, and will puncture
Bore assembly removal.
Step 6: the connecting tube of sleeve inner being connected with the gas injection valve on puncture cannula component, opens gas injection threshold switch.
When not having instrument in casing, sealing system still keeps inflated condition, this in the process can pass through other cooperation laparoscopic instruments
Puncture cannula component enters human body.
Step 7: after completing surgical procedure, gently extracting puncture cannula, staple and suture are retained in tissue, suture
It is cut in longest position.
Step 8: according to doctor's suture knotting gimmick, completing fascia tissue suture.
