Description
[technical field]
This utility model relates to medical apparatus and instruments production technical field, specifically, is a kind of knotting device for operation.
[background technology]
Sewing up knotting is the operation technique often used, and defined some operational approach sewing up knotting and specifications in surgery, a lot of surgeon is also striving to find better more effective stitching knotting operation method and technical ability.In order to well grasp these specifications and operational approach, stitching knotting device research relevant is at present also relatively perfect, but hold a sword in one's hand for doctors for operation, operation knotting first will through the training of several months, skilled grasp sews up the operant skill of tiing a knot, and could carry out surgical operation clinical middle actual holding a sword in one's hand.
Sew up method and operation that knotting is conventional wound or wound healing, stitching is drawn close by the tissue apposition cut or wound ruptures, and ties a knot after running through with suture.The quality sewed up is directly connected to the healing of tissue, and correct suture way, good suturing skill, can make wound or organize quick healing.Otherwise, after sewing up, leave dead space or intracavity hematocele, hydrops, then can cause infection; As both sides skin edge Poor fitness, then healing can be affected.Knotting is stopped blooding in surgical operation, the requisite method of tissue apposition and operation.Tie a knot and require accurate, reliable and make every effort to rapid, do not allow toe-in get loose and cause bleeding or suture tissue cracking.Knotting very commonly uses and one of important basic fundamental in operation technique.Hemostasis and stitching all need ligation, and whether ligation is firm, whether just truly have close relationship with knotting.Incorrect knotting, can make ligation slippage, and secondary hemorrhage occurs.
Current knotting method has simple hands ropework and operation tool ropework.Simple hands ropework is applicable to most of operation technique, and operation tool ropework is applicable in the stitching of superficial part, some accurate operations and degree of depth knotting operation.Correct mode to be adopted during knotting.Before knot is formed, the swing of swing type or sutural one end descend reciprocating motion can weaken sutural intensity on an opposite end, thus when making a call to second and knotting, stitching thread is earned disconnected.Even after surgery, due to ever-increasing tension force or action, sutural intensity is weakened further.If draw in the opposite direction with the same speed and tension force by sutural two ends, the knot be up to like this is more firm, and therefore knotting must ensure to be placed on position appropriate on stitching thread.The position that speed during knotting may cause line end to be put is not best.General, when making a call to the first knot, along the direction bracing wire of knotting, otherwise line frangibility, makes a call to second when knotting, first knots and does not mention, in case the first knot is lax, best bet is that assistant pushes down the first knot place by vascular forceps, when the second knot tightens up, remove pincers again.During tension suture, two handss want at 3 point-blank with force and knotting point, and both sides will be applied, and identical tension force ability is unlikely to be organized in knotting process slippage and to pull on.
And the progress of adjoint surgical technic, Minimally Invasive Surgery has the little recovery of otch soon due to it, and oneself becomes the focus direction of each disciplines of surgery development.But the technology of patient is had higher requirement simultaneously.Especially the stitching that relates to of Minimally Invasive Surgery and knotting operation, usually require that surgeon is by the apparatus of the tractive suture of special lengthening, knotting is completed under the help of assistant, or utilize the mechanical hand of operating robot to tie a knot, there is certain learning curve in above two kinds of modes especially the latter, abecedarian's speed of often tiing a knot is slow, of poor quality, and even knotting disposablely can not put in place and need repetitive operation.These factors substantially prolongs operating time above, have impact on operation safety, become the key factor that restriction Minimally Invasive Surgery is carried out.Therefore exploitation can adapt to conventional surgery knotting, a kind of device that Wicresoft ties a knot fast can also be changed simultaneously there is very important effect, the use power apparatus that this utility model connects by having thimble, hands handle device is adopted to allow the useful force feeling of people, grasp when sewing up and to exert oneself size, thus solve in stitching knotting process, human body because visual field dynamics is limited to the problem of firmly misoperation, simultaneously by the transmission effect of thimble positioning pin etc., realize the location of pin in sewing process, and connect wire twister and outer push rod with dismountable union joint, tie a knot when realizing conventional knotting process and deep Minimally Invasive Surgery and change, reduce Minimally Invasive Surgery wire twister to change, wire twister can be applicable to knotting continuously and fixed point knotting operation simultaneously.The labor intensity of the healthcare givers that the frequent replacing avoiding wire twister in continuous knotting process brings and stitching knotting cost.
