The junction of outer face, the functional areas and the inner core is provided with the open slot parallel to inner core plane, runs through the opening
The side wall of groove and the functional areas perpendicular with open slot is provided with opening, and the described one end of opening away from inner core is V-knife
Mouthful, be provided with trunking with the side wall of the relative functional areas of the opening, the trunking is along the breach in line ball face to opening
The hollow structure that groove is formed, the trunking connect with open slot；
The switch includes switch lever, switch spacing hole, switch limiting tooth, switch spring, and one end of the switch lever is consolidated
It is scheduled on the moving handle, the one end for the switch lever fixed with moving handle is provided with spring retainer post, the spring limit
Switch spring is provided between position post and the moving handle；The other end of the switch lever passes through and protrudes from switch spacing hole,
It is spacing in being provided with switch close to one end of the switch spacing hole on the switch lever between the moving handle and fixed handle
Tooth, the switch limiting tooth and switch spring are arranged on two relative sides of switch lever.
Further, first connecting rod axle and are passed through between the inner core and connecting rod, between connecting rod and moving handle respectively
Two pitman shafts are fixedly connected.
Further, the width of the switch lever between the moving handle and fixed handle is more than in switch spacing hole and switched
The width of bar, the plane that switch spacing hole is protruded from the switch lever form switch limiting tooth.
Further, the opening is positioned at the centre of the functional areas.
Further, the end of the moving handle and fixed handle is provided with handle ring.
In original state, the sleeve front end is located at opening and the open slot centre position of the functional areas, open slot
Blocked completely by sleeve, bat-handle switch is closed.
When carrying out threading operation：Handle ring described in abduction, acted on by the linkage of axle and connecting rod so that before the inner core
Move, so as to the open slot of the exposure functional areas.Now rivet line can directly be inserted out of open slot by side, avoid threading
Operation.After rivet line is inserted, interior receipts handle ring makes handle ring playback so that is moved after the inner core, so as to the sleeve
Front end is located at opening and the open slot centre position of the functional areas, and now open slot is blocked completely by sleeve, and rivet line is not
It can deviate from.After the completion of threading operation, operator can be by the functional areas position implantation surgery operating area of the thread cutter.
When carrying out line ball operation：The functional areas implantation surgery operating position of line will be put on, and keeps the rivet line put on
It is parallel with functional areas major axis, push the thread cutter and cause extruding knot in line ball face in front of functional areas, you can complete line ball operation.
When carrying out trimming operation：Operator pushes the switch so as to open switch, interior to receive the handle ring, passes through axle
Linkage with connecting rod acts on so that and moved after the inner core, the functional areas and sleeve can be made to do relative motion, the functional areas
Opening and the sleeve are cut rivet line by shear action.After completing trimming operation, the thread cutter can be grasped from operation
Make to take out in region.
Beneficial effect：The invention provides a kind of arthrocsopic surgery thread cutter of convenient threading, the present invention can be in joint
The efficiency of trimming operation is greatly enhanced in the operation of videoendoscopic surgery trimming：Before the operation of arthrocsopic surgery trimming, operator can be high
Rivet line is safely inserted thread cutter by effect again, is avoided cumbersome threading operation, has been saved the substantial amounts of time.In addition, operation
Person can further be fastened rivet knot using the line ball face of the functional areas, and the knot for avoiding accomplishing fluently loosens.Complete threading
After operation, it is only necessary to rivet line can be avoided to skid off handle ring playback；Meanwhile the switch can avoid operator from using institute
Thread cutter error before trimming operation is carried out is stated to cut rivet line in advance.So as to ensure that operator can attentively be carried out in next step
Trimming operates.The present invention can be widely applied clinically, it will the efficiency of arthrocsopic surgery is greatly improved, reduces patient complete
Stand-by period in numb art, reduce the incidence of postoperative complication.The operational efficiency and integral benefit of hospital can be improved, is reduced
Medical resource wasting phenomenon.
