The radial direction at end is outer to be socketed with shell nut 12.The front end of wire-threading device track shell 11 is bent, 11 lateral wall of wire-threading device track shell
On be symmetrically provided with two notches 111.
The one end of shell 13 far from wire-threading device track shell 11, i.e. rear end are equipped with puncture needle and push handle 21, and puncture needle pushes away
One end of handle 21 is sent to stretch out shell 13, other end connecting puncture needle fixing seat 22, puncture needle fixing seat 22 is pushed away with puncture needle
It send and is fixed between handle 21 by flexible clamping.
Shell 13 close to one end of shell nut 12, i.e., front end be equipped with can along the connector 31 that shell 13 is axially moved with
And it is set to the core filaments fixing seat 32 of 31 radially inner side of connector.Bullet is equipped between connector 31 and the radial direction of core filaments fixing seat 32
Spring 35.The lateral wall of shell 13 is equipped with wire-threading device folding and unfolding handle 33, passes through between wire-threading device folding and unfolding handle 33 and connector 31
Connecting rod 34 connects.It is pivotally connected between connecting rod 34 and wire-threading device folding and unfolding handle 33 and connector 32.
The rear end of long puncture needle 41 and short puncture needle 42 is all connected with puncture needle fixing seat 22, the puncture needle sheet of long puncture needle 41
The equal through-connections 31 of the puncture needle ontology of body and short puncture needle 42 and core filaments fixing seat 32, protrude into wire-threading device track shell
11。
The wire-threading device 5 positioned at 11 front end of wire-threading device track shell, the shape of wire-threading device 5 are equipped in wire-threading device track shell 11
With the shape adaptation of 11 front end of wire-threading device track shell, it is pivotally connected between wire-threading device 5 and wire-threading device track shell 11.Wire-threading device
5 are equipped with a core filaments fixing groove 51, and one end of spring core filaments 6 connects core filaments fixing seat 32, and it is solid that other end is fixed on core filaments
Determine in slot 51.By being pushed forward wire-threading device folding and unfolding handle 33, drive core filaments fixing seat 32 and connector 31 to far from wire-threading device track
11 side of shell is mobile, and core filaments fixing seat 32 pulls wire-threading device 5, so that wire-threading device 5 is along wire-threading device rail by spring core filaments 6
Wire-threading device track in road shell 11, it is mobile to close 13 side of shell, and two of the lateral wall from wire-threading device track shell 11
Notch 111 stretches out wire-threading device track shell 11, and wire-threading device 5 is opened.
Be additionally provided with minute hand attachment cap 52 corresponding with the tip of long puncture needle 41 on wire-threading device 5, and with short puncture needle 42
The corresponding hour hand attachment cap 53 in tip.It is connected, is connected by connecting line 54 between minute hand attachment cap 52 and hour hand attachment cap 53
Line 54 and spring core filaments 6 are axial parallel with wire-threading device 5, the two sides for wire-threading device 5 of living apart.Wherein, the tip of short puncture needle 42
Equipped with a separable needle cap 421, which can be inserted into hour hand attachment cap 53, long puncture needle when wire-threading device 5 is opened
41 tip can be inserted into minute hand attachment cap 52 when wire-threading device 5 is opened.The tip of long puncture needle 41 and can be with short puncture needle 42
The pin hole passed through for suture is equipped in the needle cap 421 at tip.
A kind of operating method of stitching unstrument for thoracoscope Minimally Invasive Surgery of the invention are as follows:
Wire-threading device track shell 11 is pushed into the minimally invasive channel in thoracic cavity by the first step, and shell nut 12 and thoracic cavity outer skin are pasted
It closes.
Second step pushes wire-threading device folding and unfolding handle 33 to 11 side of wire-threading device track shell, connector 31 is made to drive core filaments
Fixing seat 32 is far from wire-threading device track shell 11, and core filaments fixing seat 32 pulls spring core filaments 6, so that wire-threading device 5 is along wire-threading device
Wire-threading device track in track shell 11, to mobile close to 13 side of shell, and from the lateral wall of wire-threading device track shell 11
Two notches 111 stretch out wire-threading device track shell 11, and wire-threading device 5 is opened, and shell 13, which is pulled back, blocks wire-threading device 5 instead to thoracic cavity
Wall.
Third step, then push puncture needle to push handle 21 toward wire-threading device track shell 11, insert the tip of long puncture needle 41
Enter minute hand attachment cap 52, the needle cap 421 at short 42 tip of puncture needle is inserted into hour hand attachment cap 53.The needle cap 421 of short puncture needle 42 is inserted
While entering the hour hand attachment cap 53 in wire-threading device 5, separated with the tip of short puncture needle 42, needle cap 421 has been pre-installed with suture
Connection；Long puncture needle 41 is rested in minute hand attachment cap 52 and can not be detached from the mutual padlock of minute hand attachment cap 52.
4th step pushes handle 21,52 He of minute hand attachment cap to far from 11 side of wire-threading device track shell extraction puncture needle
Hour hand attachment cap 53 is connected by connecting line 54, and long puncture needle 41 can take together minute hand attachment cap 52 out of wire-threading device 5, and follow
Long puncture needle 41 back moves, and hour hand attachment cap 53 can be also carried over together, makes long puncture needle 41 and short puncture needle 42 band together
It is preset in the interior suture of wire-threading device track shell 11 out, completes suture winding movement.
5th step, shell 13 is pushed to 11 side of wire-threading device track shell is attached at shell nut 12 outside thoracic cavity again
Skin surface.
Wire-threading device folding and unfolding handle 33 is pulled back to home position to close wire-threading device 5, extracts wire-threading device track shell out by the 6th step
Suture is closed and is cut using auxiliary pusher by body 11.
A kind of stitching unstrument for thoracoscope Minimally Invasive Surgery of the invention:
It is designed by the shape of wire-threading device 5 and wire-threading device track shell 11, so that effectively suture width reaches 22mm,
Meet the requirement largely performed the operation.
By setting wire-threading device track shell 11 and shell nut 12, shell nut 12 is pushed into thoracic cavity outer skin when operation
Fitting realizes that depth that product enters human body in place, eliminates and draws blood vessel, strong operability will not be inclined because of the swing of product
From suture, it is also beneficial to the complete fitting of the interior wall of the chest.
By designing the spring core filaments 6, the core filaments fixing seat 32, connector 31, wire-threading device folding and unfolding handle that connect with wire-threading device 5
Connecting rod 34 between 33 and wire-threading device folding and unfolding handle 33 and connector 31 eliminates front end guiding catheter part, and will open
The operation of wire-threading device 5 becomes being pushed forward wire-threading device folding and unfolding handle 33 from wire-threading device folding and unfolding handle 33 of pulling back.Therefore it completes to press in doctor
After the interior wall of the chest is bonded completely and successfully sutures outer chest wall cutaneous after chest, patient is not in the case where interior wall of the chest can not stop blooding.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
