Description
Technical field
This utility model relates to a kind of medical apparatus, a kind of operation tool for laying spiral vessel dilator.
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, the easy to operate operation tool for laying spiral vessel dilator.
In order to reach object above, this utility model is adopted the following technical scheme that: for laying the operation tool of spiral vessel dilator, including 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 clamping pliers, described clamping pliers includes clamping part, handle portion and the articulated section being arranged between clamping part and handle portion, described clamping part is made up of symmetrically arranged first clamping plate and the second clamping plate, described articulated section is made up of two connecting plates that decussation is hinged, described handle portion is made up of symmetrically arranged first lever and the second lever, first clamping plate and the first lever are respectively fixedly connected with on one of them connecting plate of articulated section, second clamping plate and the second lever are respectively fixedly connected with on another connecting plate of articulated section.
The cross section of described first clamping plate and the second clamping plate is semicircle, and the lateral wall of the first clamping plate and the second clamping plate is provided with the snap ring of projection；Propping up the annular groove being provided with coupling snap ring on the inwall of stay tube, described snap ring is slidably mounted in annular groove.
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 end face sectional structure schematic diagram of clamping part.
Detailed description of the invention
nullAs shown in Figure 1，Operation tool for laying spiral vessel dilator described in the utility model includes a stay tube 1，The outer wall of described stay tube 1 is provided with draw-in groove，The inner chamber of described stay tube 1 is rotatably mounted with clamping pliers，Described clamping pliers includes clamping part、Handle portion and the articulated section 4 being arranged between clamping part and handle portion，Collectively form the jaw type mechanism for clamping object，Described clamping part is made up of symmetrically arranged first clamping plate 2 and the second clamping plate 3，Described articulated section 4 is made up of two connecting plates that decussation is hinged，Described handle portion is made up of symmetrically arranged first lever 5 and the second lever 6，First clamping plate 2 and the first lever 5 are respectively fixedly connected with on one of them connecting plate of articulated section 4，Second clamping plate 3 and the second lever 6 are respectively fixedly connected with on another connecting plate of articulated section 4.
As in figure 2 it is shown, the cross section of described first clamping plate 2 and the second clamping plate 3 is semicircle, the lateral wall of the first clamping plate 2 and the second clamping plate 3 is provided with the snap ring 7 of projection；Propping up the annular groove being provided with coupling snap ring 7 on the inwall of stay tube 1, described snap ring 7 is slidably mounted in annular groove.The when that clamping pliers rotating, retrained by annular groove so that it is the most rotatable will not move axially, the axial location of clamping pliers and a stay tube 1 can be realized.
During use, being installed on the monofilament rear end of spiral vessel dilator in the draw-in groove on stay tube 1 outer wall, the front end of monofilament is clipped between the first clamping plate 2 and the second clamping plate 3, can be screwed by monofilament 8 along hand of spiral rotating clip line tweezer.The diameter making spiral vessel dilator reduces, can be easily in implantable intravascular.After dilator inserts patient's blood vessel, somewhat turn round clamping pliers, then press the first lever 5 and the front end of monofilament 8 can be discharged by the second lever 6, take off from the draw-in groove propped up stay tube 1 outer wall in monofilament rear end subsequently, extract out.
