Abstract
This utility model provides a kind of turn silk thread mixed positioning device, belong to operation device field, comprise conduit, turn, silk thread, push rod and the trocar, described turn is placed in described conduit, described silk thread is connected with described turn, and described silk thread stretches out from one end of described conduit; The described trocar is provided with sleeve pipe, and the diameter of described turn is less than the inner diameter of described sleeve pipe; Described push rod is cylinder, and the diameter of described push rod is less than the inner diameter of described sleeve pipe, and the diameter of described push rod is less than the inner diameter of described conduit.The positioner of this design, by turn and silk thread implant into body tissue, the soft characteristic of silk thread, has reduced the damage to tissue, and turn inside contracts into bulk in tissue, in the process relatively moving at organ, bulk turn difficult drop-off, once there is the complication such as hemorrhage, blood flow is crossed turn, easily produce thrombosis, there is the effect of hemostasis shutoff.
Description
Technical field
This utility model relates to operation device field, in particular to turn silk thread mixed positioning device.
Background technology
For the Minimally Invasive Surgery of tumor, locate accurately extremely important.The wider tumor-localizing technology of clinical middle application is at present the property implanted location, mostly current implantation location technology is to adopt buckle steel wire navigation system, by lancet puncture tumor focus, and implanted metal steel wire, then use the agnail of steel wire front end to tangle tissue, then carry out excision.Prior art adopts buckle stainless steel silk, its material is harder, in the process moving in tissue, the tractive that hard steel wire produces can cause the damage of tissue, and steel wire hook also can cause the damage of tissue, and then the complication of increase operation, in addition,, in operation process, steel wire lacks flexibility, easily come off, cause operative failure.
Utility model content
The purpose of this utility model is to provide a kind of turn silk thread mixed positioning device, is intended to reduce the damage of tumor-localizing device to tissue, and reduces the probability coming off after positioner implant into body.
This utility model is achieved in that
A kind of turn silk thread mixed positioning device, comprises conduit, turn, silk thread, push rod and the trocar, and described turn is placed in described conduit, and described silk thread is connected with described turn, and described silk thread stretches out from one end of described conduit; The described trocar is provided with sleeve pipe, and the diameter of described turn is less than the inner diameter of described sleeve pipe; Described push rod is cylinder, and the diameter of described push rod is less than the inner diameter of described sleeve pipe, and the diameter of described push rod is less than the inner diameter of described conduit.
Further, described sleeve pipe is tack.The damage that tack sleeve pipe has avoided tip sleeve pipe to bring to tissue.
Further, the described trocar is provided with nook closing member, and the diameter of described push rod is less than the diameter of described nook closing member.The push rod of small diameter can reduce push rod in the time pushing sleeve pipe and the friction of internal surface of sleeve pipe, makes push operation more laborsaving.
Further, the diameter of described turn is less than the diameter of described nook closing member.The turn of small diameter can reduce turn in the time being pushed into sleeve pipe and the friction of internal surface of sleeve pipe, makes turn implant procedure more laborsaving.
Further, the inwall of described nook closing member and described sleeve pipe laminating.The inwall laminating of nook closing member and sleeve pipe, while having ensured trocar puncturing tissue, sleeve pipe thrusts tissue with nook closing member.
Further, described silk thread is a surgical thread.No. one surgical thread is comparatively soft, reduces the damage to tissue.
Further, described turn is fixedly connected with described silk thread.Turn is fixedly connected with silk thread, prevents that silk thread from separating in the process of implant into body tissue with turn.
Further, the inner diameter of described conduit is identical with the inner diameter of described sleeve pipe.Conduit and the sleeve pipe coupling on inner diameter, is conducive to the turn in conduit to push the operation of sleeve pipe.
This utility model is connected turn with silk thread, and be placed in conduit, after trocar puncturing tissue, sleeve pipe stays in tissue, take out nook closing member, and one end that does not connect silk thread of conduit is aimed at and joined with the opening of the trocar, by push rod, turn and silk thread are pushed to tissue along conduit, take out sleeve pipe, a part for turn and silk thread is stayed in tissue, turn inside contracts into bulk in tissue, tangles tissue, thereby realizes the preoperative location to tumor resection.The beneficial effects of the utility model are: the positioner of this design, by turn and silk thread implant into body tissue, the soft characteristic of silk thread, has reduced the damage to tissue, and turn inside contracts into bulk in tissue, in the process relatively moving at organ, bulk turn difficult drop-off, once there is the complication such as hemorrhage, blood flow is crossed turn, easily produce thrombosis, there is the effect of hemostasis shutoff.
