Working principle
One, threading apparatus working principle
1, ensure that the locating fastener 21 latched on 19 is in the upper locating location slot 30 on shell before use, it is movable at this time
Bracket is tightened completely, and threading apparatus is in tightening state.
2, pushing down two side locks 19 makes 20 compressive deformation of latch spring, and locating fastener 21 is detached from upper locating location slot at this time
28, then downward 30 direction of locating location slot pulls lock 19, while driving movable axis 18, motion bar 16 and movable support head
It slides downwardly together, movable support upper arm 10 and movable support lower arm 11 slowly strut therewith at this time, 21 sliding of buckle to be positioned
Two side locks 19 are unclamped when near to lower locating location slot 30, latch spring 20 flicks two side locks at this time, locating fastener 21
Enter in lower locating location slot 30 therewith, 19 positions of lock locking, movable support struts completely, and threading apparatus enters softened state.
3, pushing down two side locks 19 makes 20 compressive deformation of latch spring, and locating fastener 21 is detached from lower locating location slot at this time
30,28 direction of locating location slot pushes lock then up, while driving movable axis 18, motion bar 16 and movable support head one
Upward sliding is played, movable support upper arm 10 and movable support lower arm 11 are slowly tightened therewith at this time, and buckle 21 to be positioned slides into
Two side locks 19 are unclamped when near upper locating location slot 30, latch spring 20 flicks two side locks 19 at this time, locating fastener 21
Enter in upper locating location slot 28 therewith, 19 positions of lock locking, movable support is tightened completely, and threading apparatus enters tightening state.
Two, hooking device working principle
1, ensure that the Elastic buckle 14-2 on activity lock 14 is in handle outer before use, hooking device, which is in, at this time unclamps
State.
2, the button 14-1 on pressure activity lock 14, makes activity 14 slide downwards of lock, and activity lock 14 pushes hooking
Activity lock reset spring 37 and hooking needle tubing seat 47 in needle tubing seat sliding sleeve 14-3 slide downwardly together, while hooking needle tubing
Seat boss 36-4 pushes hooking needle assemblies reset spring 38 to be allowed to compressive deformation, until hooking needle assemblies are arrived on the top of hooking needle tubing seat 47
Reset spring block 39, hooking needle assemblies 36 stop sliding at this time, and hooking syringe needle 36-3, which exposes puncture tube 5-1 and restores compression, to be become
Shape before shape is in opened condition.
3, continue the button 14-1 on pressure activity lock 14, activity lock 14 is made to continue slide downward and activity compression lock
Reset spring 37 is detained, hooking needle tubing seat 36-2 and hooking needle assemblies reset spring 38 are in 47 sliding sleeve of hooking needle tubing seat at this time
In stationary state, when activity lock 14 is pushed up to when puncturing tube socket, activity lock 14 pushes puncture tube assembly 5 to slide downwardly together,
Tube socket boss 5-3 is punctured simultaneously and pushes puncture 40 compressive deformation of tube assembly reset spring, and puncture tube 5-1 is slowly covered to hooking at this time
Syringe needle 36-3 is simultaneously allowed to compression tightening.
4, the button on pressure activity lock 14 is continued to, until the Elastic buckle 14-2 on activity lock 14 enters assistant
In movable locating location hole 46 on handle, the locking of 14 positions of activity lock, hooking syringe needle 36-3 are completely nested puncture tube 5-1 at this time
Interior, hooking device enters tightening state.
5, the Elastic buckle 14-2 on activity lock 14 is pressed, Elastic buckle 14-2 disengaging activity locating location hole 46 is made,
At this time in activity lock reset spring 37, hooking needle assemblies reset spring 38 and the effect respectively for puncturing tube assembly reset spring 40
Under, activity lock 14, hooking needle assemblies 36 and puncture tube assembly 5 are slided and are resetted rapidly upward, and hooking device enters releasing orientation.
Three, overall work principle
1, ensure that threading apparatus is in tightening state before use, hooking device is in releasing orientation.
2, suture 48 is sequentially clamped in the winding slot 35 on the cable clamping interface 4 and wire spool 34 of threading apparatus side, 4 He of cable clamping interface
Winding slot 35 defines that the position of suture is allowed to not easily to fall off, and suture 48 is then bypassed rubber pad along one side surface of movable support
7 reach another side surface of movable support, while the suture of corresponding site being caught in the groove on 7 surface of rubber pad, make suture 48 not
It is easy to fall off, then suture 48 is sequentially clamped in winding slot 35 and cable clamping interface 4 on threading apparatus other side wire spool 34, suture 48 at this time
Winding is completed.
3, threading apparatus is inserted into 49 notch of stomach wall or puncturing hole, avoids damage to surrounding tissue during insertion.
4, it pushes down downward 30 direction of locating location slot of two side lock of threading apparatus 19 to pull, until locating fastener 21 enters lower lock
It detains in locating slot 30,19 positions of lock locking, movable support struts completely, and threading apparatus enters softened state.
5, hooking device is inserted into along the hooking device pilot hole 3 on threading apparatus, and the elastic card on guarantee activity lock 14
Detain the direction 14-2 outwardly, the head puncture tube 5-1 on hooking device passes through 49 lower-hierarchy of stomach wall after passing through hooking device pilot hole 3,
Subsequently into the inside of hooking hole 6 on movable support lower arm 11, the shell on the handle top of hooking device to threading apparatus at this time, hooking device
On hooking device fixing groove 45 match with the arc-shaped surface on threading apparatus shell, hooking device cannot be rotated arbitrarily.
6, the button 14-1 on pressure activity lock 14 becomes when hooking syringe needle 36-3 exposes puncture tube 5-1 and restores compression
When shape before shape, two sides of hooking syringe needle 36-3 are placed exactly in 48 two sides of suture and only slight beyond sutures 48, in order to hook
Suture 48 is caught on when line syringe needle 36-3 compression tightening.
7, continue the button 14-1 on pressure activity lock 14, puncture tube 5-1 is slowly covered to hooking syringe needle 36-3 and is allowed to
Compression tightening, hooking syringe needle 36-3 are then slowly hooked to suture.
8, the button 14-1 on pressure activity lock 14 is continued to, until the Elastic buckle 14-2 on activity lock 14 enters
In movable locating location hole 46 on lower handle 12, the locking of 14 positions of activity lock, hooking syringe needle 36-3 catch on seam completely at this time
Line 48 is simultaneously inserted in puncture tube 5-1, and hooking device enters tightening state.
9, hooking device is extracted along the hooking device pilot hole 3 on threading apparatus, at the same by one end of suture 48 successively along
49 lower-hierarchy of stomach wall and hooking device pilot hole 3 are taken out of and are stayed in outside threading apparatus.
10, the Elastic buckle 14-2 on hooking device activity lock 14 is pressed, hooking device is made to enter releasing orientation.
11, step 5 is repeated to 9, hooking device is inserted into along the hooking device pilot hole 3 of the other side on threading apparatus, and will seam
The other end of line 48 is taken out of outside threading apparatus.
12, it pushes down upward 28 direction of locating location slot of two side lock of threading apparatus 19 to push, until the entrance of locating fastener 21 is upper
In locating location slot 28,19 positions of lock locking, movable support is tightened completely, and threading apparatus enters tightening state.
13, threading apparatus is extracted from 49 notch of stomach wall or puncturing hole, surrounding tissue is avoided damage in withdrawal process.
14, due to during hooking suture 48 have disengaged from the winding slot 35 on wire spool 34, when extracting threading apparatus, threading
Device has just smoothly stayed in outside 49 notch of stomach wall or puncturing hole departing from suture 48 and the both ends of suture 48, and in suture 48
Portion then stays in 49 lower-hierarchy of stomach wall in 49 notch of stomach wall or puncturing hole and passing through two sides.
15, fascia sewing work conventionally, is carried out, also suture 48 is hitched and removes 48 redundance of suture
It removes.
