The content of the invention
The technical problem to be solved in the present invention, aiming at the deficiency present in prior art, and provide a kind of laparoscope
Surgical suture knotter, the knotter knotting operation is simple, and required operating space is small.
This programme is achieved by the following technical measures：The laparoscopic surgery with stitching knotter include handle portion,
The body of rod and knotting portion, the knotting portion include two it is be hinged with rod end and by handle portion drive can opening and closing clamping pliers, when
During the jaw closure of two clamping pliers, knotting portion is in the shape of a spiral.
When the jaw closure of two clamping pliers, the end in knotting portion is in tip-shape, and this tip-shape structure is easy to pick up
Suture.
Above-mentioned handle portion includes fixed handle and flexible handle, one end of the flexible handle stretch into fixed handle inner chamber and
Its middle part is hinged with fixed handle, and two clamping pliers opening and closing are driven by flexible handle to facilitate.
The guide rod coordinated with its gap is provided with the above-mentioned body of rod, one end of guide rod and flexible handle are be hinged, another
End is hinged by linkage and two clamping pliers, and flexible handle drives the opening and closing of two clamping pliers by guide rod.
Aforementioned link mechanism includes connecting rod A and connecting rod B, connecting rod A and guide rod lower hinge, connecting rod B and guide rod
End of upper articulation, connecting rod A and connecting rod the B other end respectively with two clamping pliers is hinged, and this structure type can the company of avoiding
There is dead point in bar A and connecting rod B, to ensure being smoothed out for operation stitching.
Jagged with the setting of connecting rod A and connecting rod B hinged end in above-mentioned two clamping pliers, the breach is arranged on two clamping pliers
Opposite flank on, the setting of breach can reduce the friction between connecting rod A and connecting rod B.
The circulator being adapted with forefinger is fixed with the above-mentioned body of rod close to one end of handle portion.
The one end being connected in above-mentioned flexible handle with guide rod is also associated with back-moving spring, and the other end of back-moving spring is with consolidating
Determine the inwall connection of handle, pressing flexible handle opens two clamping pliers, after suture is wound, lifts finger, then be aided with
The reset drives effect of back-moving spring, guide rod quickly can smoothly reset, close two clamping pliers and clamp suture.
The beneficial effect of this programme can learn according to the narration to such scheme, the laparoscopic surgery stitching knotter
In, knotting portion include two it is be hinged with rod end and by handle portion drive can opening and closing clamping pliers, when the jaw of two clamping pliers
During closure, in the shape of a spiral, during knotting, stirring circulator by forefinger revolves spiral helicine knotting portion in knotting portion
Turn, and hook quickly completes spooling step around suture, and complete to knot, can prevent from stitching in winding process during this
Zygonema comes off, and suture is firmly wrapped on clamping pliers, and its is simple to operate, rapid, and the required space that knots is smaller.By
This is visible, and the present invention compared with prior art, has prominent substantive distinguishing features and significant progressive, its beneficial effect implemented
It is and obvious.

Embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, and its accompanying drawing is combined, to we
Case is illustrated.
A kind of laparoscopic surgery stitching knotter, as illustrated, it includes handle portion 5, the body of rod 2 and knotting portion 1, the body of rod
The circulator 4 being adapted with forefinger is fixed with 2 on the outside of one end of handle portion 5, the knotting portion 1 includes two and the body of rod
2 ends it is be hinged and by handle portion 5 drive can opening and closing clamping pliers 13.When the jaw closure of two clamping pliers 13, knotting portion 1 is overall
In the shape of a spiral, so suture is made to be twined in the shape of a spiral in knotting portion 1 when circulator 4 drives knotting portion 1 to rotate by the body of rod 2
Around, will not fall off suture, complete spooling step.And when the jaw closure of two clamping pliers 13, the end in knotting portion 1 is in point
Shape is held, this structure type is beneficial to pick up suture with two clamping pliers 13 and knotted.
The handle portion 5 includes fixed handle 6 and flexible handle 7, and fixed handle 6 is stretched into one end of the flexible handle 7
Inner chamber, and the middle part of flexible handle 7 and fixed handle 6 are be hinged, ensure that flexible handle 7 can be hinged with fixed handle 6 around it
Point rotation.
It is provided with the guide rod 3 coordinated with its gap in the body of rod 2, one end of guide rod 3 and flexible handle 7 be hinged,
The other end is be hinged by linkage and two clamping pliers 13.The one end being connected in flexible handle 7 with guide rod 3 is also associated with resetting
Spring 8, the other end of back-moving spring 8 are connected with the inwall of fixed handle 6.
Aforementioned link mechanism includes connecting rod A11 and connecting rod B12, connecting rod A11 and guide rod 3 lower hinge, connecting rod B12 with
End of the upper articulation of guide rod 3, connecting rod A11 and connecting rod the B12 other end respectively with two clamping pliers 13 is hinged.Two clamping pliers
Jagged 10 are set with connecting rod A11 and connecting rod B12 hinged end in 13, the breach 10 is arranged on the opposite side of two clamping pliers 13
On face.Flexible handle 7 is pressed downwards, guide rod 3 is moved to handle end, drivening rod A11 and connecting rod when guide rod 3 moves
B12 synchronization actions, make two clamping pliers, 13 open-shaped state, prepare clamp.During clamp, finger is lifted up driving movable hand simultaneously
Lifted on handle 7, then be aided with the reset drives effect of back-moving spring 8, guide rod 3 quickly can smoothly reset, and make two clamping pliers 13
Close and clamp suture.
During knotting, common ligaturing forceps are clamped with one one end of suture, and suture are taken to the outside of clamping pliers 13,
Then with forefinger rotation circulator 4 suture can be made to be wrapped in spiral helicine knotting portion 1, quickly completes spooling step, then
The other end of suture is clamped with the clamping pliers 13 of the knotter, the both ends of suture are tensed and can be achieved to knot, due to seam
The knotter need to only rotate when zygonema is wound, so operating space required when knotting is small, it is simple to operate, beneficial to operation
Be smoothed out.
The technical characteristic without description can be achieved by the prior art in the present invention, will not be repeated here.The present invention is simultaneously
