Abstract

Abstract A videoendoscopic knot pusher comprises a main body (300) and first and second fingers (312, 322) whose ends are shaped in a smooth rounded shape to guide a suture and knot into position with a patient's body. The finger members (312, 3322) define either a 'V'-shaped cleft or a smooth walled channel (330) between them for grasping the suture. Second and third channels (340, 350) or a spiral channel formed 'upstream' of the finger members retain the suture in the fingers even during retraction of the main body for retaining control of the suture even if the suture slips out of the grasp of the channels.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 56 words
A knot pusher (100;200;200;400) for use in videoendoscopic surgery, comprising: a main body member (102;202;302;402) formed of a rigid material suitable for sterilization; one end of the main body member formed into first and second outwardly extending finger members (110,120;210,220;310, 320;410,420); the first and second finger members each have rounded and tapered ends (112,122;212,222;312,322;412,422) formed thereon.
Claim 2
Dependent Claim 22 words
The knot pusher claimed in claim 1, wherein: a 'V'-shaped cleft (126;226) is formed between the first and second finger members (110,120;210,220).
Claim 3
Dependent Claim 23 words
The knot pusher claimed in claim 1, wherein: a first 'U'-shaped slot (330;430) is formed between the first and second finger members (310,320;410,420).
Claim 4
Dependent Claim 29 words
The knot pusher claimed in claim 1, wherein: a rigid elbow (270) is formed in the main body member (200) adjacent and upstream the first and second finger members.
Claim 5
Dependent Claim 64 words
The knot pusher claimed in claim 3, wherein: the first 'U'-shaped slot (330) is formed on an upper surface of the main body member (300); a second 'U'-shaped slot (350) is formed in the bottom of the main body member (300); a third transverse slot (340) is formed in the main body member (300) to interconnect the first and second 'U'-shaped slot members (330,350).
Claim 6
Dependent Claim 45 words
The knot pusher claimed in claim 3, wherein: a spiral groove (440) is formed in the outer surface of the main body member (400) in a right hand direction of rotation; the spiral groove (440) communicates at one end with the first'U'-shaped slot member (430).
Claim 7
Dependent Claim 37 words
The knot pusher claimed in claim 2 for pushing knots formed in surgical suture material which has a diameter, wherein: the 'V' cleft (126;226) has a width only slightly larger than the diameter of the suture material.
Claim 8
Dependent Claim 37 words
The knot pusher claimed in claim 3 for pushing knots formed in surgical suture material which has a diameter, wherein: the 'U'-shaped channel (330;430) has a width only slightly larger than the diameter of the suture material.
