Description
Technical field
This utility model relates to a kind of medical apparatus, a kind of vessel dilator implanting instrument.
Background technology
At present, conventional cardiovascular expansion operation mainly mounting bracket or sacculus, owing to cardiovascular pipeline is thinner, operation process operate pretty troublesome.The installation of support and the adjustment of position will take a significant amount of time and energy, bring difficulty and risk to operation.Chinese patent 2010202319042 discloses one " cardiovascular expansion device " and is previously installed at by network in a guide wire, a tube core is also installed in guide wire simultaneously, first by guide wire implantable intravascular during operation, network is released by recycling tube core.This " cardiovascular expansion device ", although operation technique can be simplified to a certain extent, improves the accuracy that network puts in place, but owing to the diameter of guide wire is more than the diameter of network, its scope of application is restricted, and the most also can increase the difficulty of operation；Another Chinese patent 2013200482005 discloses one " cardiovascular expansion device ", it uses the helix tube type dilator that single thread spiral is wound, and in the inner chamber of serpentine pipe, it is provided with support bar, the front end of support bar is provided with fixation fork, the stage casing of support bar is provided with hole, location, monofilament is wound around on support bar, the two ends of monofilament are inserted in fixation fork and hole, location respectively, after putting blood vessel into, unclamp the two ends of monofilament, extract support bar out, filament diameter is expanded automatically, play the effect of expansion and support blood vessels wall, its simple in construction, easy to operate, have wide range of applications.But owing to its support bar is the fixed structure of integral type, support bar is installed and to discharge the operation at monofilament two ends extremely difficult, during extracting support bar out by the monofilament ribbon of half release conditions the most out, cause operative failure.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, easy to operate vessel dilator implanting instrument.
In order to reach object above, this utility model is adopted the following technical scheme that: this vessel dilator implanting instrument includes a stay tube, the outer wall of described stay tube is provided with draw-in groove, the inner chamber of described stay tube is rotatably mounted with axis, the front end of described axis is with monofilament hook, the rear end of axis is fixing connects handle, at handle towards on the end face of a stay tube, be uniformly distributed multiple alignment pin around axis, the end face of a stay tube is provided with the hole, location of coupling alignment pin.
Described monofilament hook is that opening is towards the diametric groove of axis.
Described monofilament hook is to be oppositely arranged, by two clamping plate, the clamp formed.
Being provided with annular groove on the inwall of a stay tube, the correspondence position of axis is fixedly installed the clip of projection, and the cooperation of described clip is arranged in annular groove, and the width of annular groove is more than the width of clip.
The beneficial effects of the utility model are: can clamp spiral vessel dilator easily and be tightened, reduce caliber, facilitate implant procedure, implant after can unclamp again dilator easily, this instrument is taken out, its simple in construction, easy to operate, have wide range of applications.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of this utility model.
Fig. 2 is the structural representation of another embodiment of this utility model.
Detailed description of the invention
As it is shown in figure 1, vessel dilator implanting instrument described in the utility model includes a stay tube 1, the outer wall of described stay tube 1 is provided with draw-in groove, for one end of the spiral vessel dilator of clamping.The inner chamber of described stay tube 1 is rotatably mounted with axis 2, the front end of described axis 2 with monofilament hook 3, described monofilament hook 3 be opening towards the diametric groove of axis 2, the other end of spiral vessel dilator can be blocked.The rear end of axis 2 is fixing connects handle 4, at handle 4 towards on the end face of a stay tube 1, be uniformly distributed multiple alignment pin 5 around axis 2, the end face of a stay tube 1 is provided with the hole, location of coupling alignment pin 5.Driving handle 4 can inject in hole, location by corresponding for alignment pin 5, by the position locking of handle 4 with a stay tube 1 forward.
It addition, be provided with annular groove 6 on the inwall of a stay tube 1, the correspondence position of axis 2 is fixedly installed the clip 7 of projection, and the cooperation of described clip 7 is arranged in annular groove 6, and the width of annular groove 6 is more than the width of clip 7.On the one hand the width of annular groove 6 allows axis 2 can have certain shaft orientation moving range, limits again its distance moved axially simultaneously.
As in figure 2 it is shown, another embodiment of the present utility model.Described monofilament hook 3 is to be oppositely arranged, by two clamping plate, the clamp formed.
During use, the monofilament rear end of spiral vessel dilator is installed in the draw-in groove on stay tube 1 outer wall, the front end of monofilament hangs on monofilament hook 3, monofilament 8 can be screwed along hand of spiral rotating middle shaft 2, alignment pin 5 is injected in hole, location by driving handle 4, its position is locked, can avoid unclamping dilator resilience after hands.Now the diameter of spiral vessel dilator reduces, can be easily in implantable intravascular.After dilator inserts patient's blood vessel, extract handle 4 and somewhat turn round axis 2, the front end of dilator can be discharged, take off from the draw-in groove propped up stay tube 1 outer wall in monofilament rear end subsequently, extract out.
