Description
Technical field
This utility model relates to a kind of medical apparatus, a kind of vessel dilator implant surgery 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 implant surgery instrument.
In order to reach object above, this utility model is adopted the following technical scheme that: vessel dilator implant surgery instrument includes the push rod that handle, plug-in mounting are axially movable in the handle, the rear end of described push rod is provided with pressing plate, spiral chuck it is set with on described push rod, described spiral chuck is to be formed by special-shaped monofilament helical coil, the upper/lower terminal in described special-shaped monofilament cross section is symmetrically arranged with clamping spiral and lower clamping spiral, one end of special-shaped monofilament is fixedly connected on the front end of push rod, and the other end of special-shaped monofilament is fixedly connected on handle.
The recessed arc helicla flute that described upper clamping spiral and lower clamping spiral are provided on special-shaped monofilament, described arc helicla flute be arranged in parallel with special-shaped monofilament.
Symmetrically arranged two cross sections, two ends up and down that described special-shaped monofilament includes columned monofilament body, be fixedly connected on monofilament body are the spiral lamina of arc.
It is provided with axially arranged keyway on the inwall of described handle, described push rod is provided with the spline mating this keyway.
The beneficial effects of the utility model are: screw clamp set utilizes the upper clamping spiral of both sides and lower clamping spiral to clamp the most spiral-shaped vessel dilator, the state be at compression, tightening, caliber is less, facilitate the operation of implantable intravascular, by push rod tensile coil chuck after implanting, dilator can be discharged again easily, this instrument is taken out, its simple in construction, easy to operate, have wide range of applications.

Detailed description of the invention
As shown in Figure 1, vessel dilator implant surgery instrument described in the utility model includes handle 1, is inserted in handle 1 push rod 2 being axially movable, the rear end of described push rod 2 is provided with pressing plate 3, and handle 1 is column structure, can slide axially by dynamic pressure plate 3, push rod 2 in handle 1.Being set with spiral chuck 4 on described push rod 2, described spiral chuck 4 is by the helical structure of special-shaped monofilament helical coil, and the material of spiral chuck 4 uses resilient plastics, rustless steel etc. to make.The upper/lower terminal in described special-shaped monofilament cross section is symmetrically arranged with clamping spiral 5 and lower clamping spiral 6, and one end of special-shaped monofilament is fixedly connected on the front end of push rod 2, and the other end of special-shaped monofilament is fixedly connected on handle 1.
As shown in Figure 3, Figure 4, the recessed arc helicla flute that described upper clamping spiral 5 and lower clamping spiral 6 are provided on special-shaped monofilament, described arc helicla flute be arranged in parallel with special-shaped monofilament.The body of special-shaped monofilament can use cylindrical structure as depicted, it would however also be possible to employ cross section is the rectangular cylinder structure of rectangle, or cross section is oval Elliptic Cylinder structure.
As it is shown in figure 5, as another embodiment of the present utility model, described special-shaped monofilament includes columned monofilament body 41, is fixedly connected on the spiral lamina 51,61 that symmetrically arranged two cross sections, two ends up and down are arc of monofilament body 41.
It addition, be provided with axially arranged keyway on the inwall of described handle 1, described push rod 2 is provided with the spline 51 mating this keyway.So can only be moved axially by keyway restriction push rod 2 and can not rotate, can also limit, by the length rationally arranging keyway, the scope that push rod 2 moves axially simultaneously.
As shown in Figure 2, during use, the monofilament of spiral vessel dilator is installed between upper clamping spiral 5 and lower clamping spiral 6, owing to the pitch of spiral chuck 4 is from i.e. above clamping the diameter less than spiral-expanding device monofilament of the distance between spiral 5 and lower clamping spiral 6, now spiral chuck 4 can be clamped dilator and makes it to get loose, can be easily in implantable intravascular.Dilator inserts after patient's blood vessel, and pressing pressing plate 3 is expanded by push rod tensile coil chuck 4, the spiral shell spacing of spiral chuck 4, i.e. releasable dilator, dilator be released after its enlarged-diameter, be supported on Blood of Patients tube wall, now this instrument can be taken out.
