Abstract
The utility model discloses a push rod. The push rod comprises inner core threads, spring winding wires, a handle and a tightening screw; the spring winding wires surround the peripheral surface of the inner core threads in a mobile mode; the length of the inner core threads is larger than that of the spring winding wires; the handle is connected to the rear end of the inner core threads in a sleeve mode; the tightening screw is installed on the handle; a tail portion of the tightening screw is in contact with the peripheral surface of the inner core threads. According to the push rod, the inner core threads and the external spring winding wires can move relatively, the spring winding wires can be withdrew and only the inner core threads and the plugging device are in contact when the plugging device is well placed, and the inner core threads are soft, so that influences to states of the plugging device are reduced and better reference values are provided for observing an actual plugging effect of the plugging device.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of push rod.
Background technology
At present existing polytype stopper is used for the treatment of congenital heart disease, and these stoppers are delivered to the specific position of patient's heart by conduit.
Refer to Fig. 1, the push rod structure using in stopper intervene operation is in the market fixed, push rod comprise inner core silk 1 ' and be looped around the spring wrapping wire 2 of inner core silk 1 ' outside ', spring wrapping wire 2 ' front and back ends respectively with inner core silk 1 ' be fixedly connected with, spring wrapping wire 2 ' rear end be socketed with handle 3 ', handle 3 ' be provided with trip bolt 4 ', trip bolt 4 ' afterbody and spring wrapping wire 2 ' outer peripheral face contact setting.Inner core silk 1 ' be fixedly connected with spring wrapping wire 2 ' employing as welding, cannot relatively move.
In occluder, stopper is placed on behind heart defect position and can't stopper be separated with push rod at once, but need to first detect the whether suitable of stopper placement, whether plugging effect is satisfied with.Because push rod itself has certain elasticity, so can be because push rod bending causes the additional effect power to stopper in the situation that not discharging stopper, the state of stopper is undernatured state in this case, be different from the state departing from completely after push rod, affect the reference value of the actual plugging effect of testing result to stopper.
Summary of the invention
The purpose of this utility model is that a kind of push rod is provided in order to address the above problem, inner core silk and the spring wrapping wire of this push rod can relatively move, placing after stopper, spring wrapping wire can be stepped back, only stay inner core silk and stopper to keep being connected, because inner core silk is softer, so reduced the impact on stopper form, the actual plugging effect of observing stopper is had to better reference value.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of push rod, comprise inner core silk, spring wrapping wire, handle and trip bolt, wherein:
Described spring wrapping wire is looped around the outer peripheral face of described inner core silk movably, and the length of described inner core silk is greater than the length of described spring wrapping wire;
Described taper knob is connected on the rear end of described inner core silk;
Described trip bolt is arranged on described handle, and the afterbody of described trip bolt contacts setting with the outer peripheral face of described inner core silk.
Above-mentioned a kind of push rod, wherein, on described handle, laterally offer a through hole, described handle is socketed in the rear end of described inner core silk by this through hole, a screwed hole is offered in the position of the top that is positioned at described through hole of described handle, and the afterbody of described trip bolt penetrates described screwed hole and contacts setting with the corresponding outer peripheral face of described inner core silk.
Above-mentioned a kind of push rod, wherein, the front end of described inner core silk is provided with thread head.
The beneficial effect that compared with prior art push rod of the present utility model has is: because inner core silk and the spring wrapping wire of push rod can relatively move, placing after stopper, spring wrapping wire can be stepped back, only stay inner core silk and stopper to keep being connected, because inner core silk is softer, so reduced the impact on stopper form, the actual plugging effect of observing stopper had to better reference value.
Brief description of the drawings
Fig. 1 is the structural representation of the push rod of prior art;
Fig. 2 is the structural representation of push rod of the present utility model.
Detailed description of the invention
Inventor of the present utility model is in order to understand the technical solution of the utility model better, below by embodiment particularly, and is described in detail by reference to the accompanying drawings.
Refer to Fig. 2, embodiment of the present utility model, a kind of push rod, comprises inner core silk 1, spring wrapping wire 2, handle 3 and trip bolt 4.Spring wrapping wire 2 is looped around the outer peripheral face of inner core silk 1 movably, and the length of inner core silk 1 is greater than the length of spring wrapping wire 2, makes spring wrapping wire 2 on inner core silk 1, have enough mobile surpluses, can make spring wrapping wire 2 move around on inner core silk 1, handled easily; Handle 3 is socketed in the rear end of inner core silk 1; Trip bolt 4 is arranged on handle 3, and the afterbody of trip bolt 4 contacts setting with the outer peripheral face of inner core silk 1.
On handle 3, laterally offer a through hole, handle 3 is socketed in the rear end of inner core silk 1 by this through hole, and a screwed hole is offered in the position of the top that is positioned at through hole of handle 2, and the afterbody of trip bolt 4 penetrates screwed hole and contacts setting with the corresponding outer peripheral face of inner core silk 1.The front end of inner core silk 1 is provided with thread head 5.
In stopper intervene operation, use push rod of the present utility model, in the time that stopper is pushed to human body, the front end of outer ring wrapping wire 2 can withstand on the rear end of thread head 5, ensures to transmit enough propelling movement power.Because inner core silk 1 and the spring wrapping wire 2 of push rod can relatively move, placing after stopper, can first spring wrapping wire 2 stepped back, only staying inner core silk 1 and stopper to keep being connected, and then detect whether suitable that stopper is placed, whether plugging effect is satisfied with.Because inner core silk 1 is softer, so reduced the impact on stopper form, the actual plugging effect of observing stopper is had to better reference value.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
