Description
Technical field
The utility model belongs to medical interventions instrument field, is related to a kind of coronary artery locating support system.
Background technique
Percutantnoeus coronary intervention releases the narrow of diseased region by balloon expandable and bracket merging, is to treat having for coronary heart disease
Efficacious prescriptions method.And for certain opening lesions, accurate positioning support is difficult.Especially in heartbeat, bracket is in the blood vessel
When front and back play amplitude is big.Above situation is it occur frequently that coronary artery bracket can not position or position unsatisfied situation, directly
Cause to intervene operative failure or severe complication, is the problem of the current calcification score of puzzlement.It is applied to clinical branch at present
The problem of frame system still remains location difficulty.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of coronary artery locating support systems, in coronary artery
Bracket can be accurately positioned and be discharged using the set system in interventional procedure.
In order to achieve the above objectives, the utility model provides the following technical solutions:
Coronary artery locating support system, including seal wire, bracket, anchoring device and positioning device, the anchoring device packet
Hollow conduit and the anchoring balloon that catheter proximal end is set are included, the positioning device can be along conduit including being set on conduit
Casing in axial sliding and be arranged in casing front end for discharging the resilient bladder of bracket, the conduit and anchoring balloon
It is connected to by first passage, described sleeve pipe is connected to resilient bladder by second channel, and described sleeve pipe is slidably disposed on rail
In road, the rear end of casing is equipped with rack gear, be correspondingly arranged on the track with the rack gear meshed gears, connect on the gear
It is connected to rotational handle.
It further, further include the elastic connection section being arranged in described sleeve pipe, the elastic connection section is arranged in elastic ball
Between capsule and rack gear.
Further, developing ring is equipped with positioned at the both ends of anchoring balloon on conduit.
Further, developing ring is equipped with positioned at the both ends of resilient bladder on casing.
The utility model has the beneficial effects that: present apparatus casing can under the drive of gear forward slip, make to position
Position can according to need and be determined, improve success rate of operation.By the way that elastic connection section, Ke Yi are arranged on casing
When accurate adjustment resilient bladder, is buffered, allow the position fixing process of resilient bladder gradually to carry out, keep position fixing process more stable.
Detailed description of the invention
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, the utility model provides as follows
Attached drawing is illustrated:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
The utility model coronary artery locating support system as shown in Figure 1, including seal wire 1, bracket 2, anchoring device and fixed
Position device, the anchoring device include hollow conduit 11 and the anchoring balloon 3 that 11 front end of conduit is arranged in, the positioning device
Including be set on conduit 11 can along conduit 11 casing in axial sliding 4 and be arranged in 4 front end of casing for discharging
The resilient bladder 5 of bracket, the conduit 11 are connected to anchoring balloon 3 by first passage, and described sleeve pipe 4 and resilient bladder 5 are logical
Second channel connection is crossed, the inside of conduit 11 is arranged in first passage, connects priming device, second channel by the first connector 6
The inside of casing 4 is set, priming device is connected by the second connector 7, specific connection type and fluid injection mode are all existing
Mode.
In the present embodiment, casing 4 is slidably disposed in track 8, and track 8 is connected with conduit 11, after casing 4
End is equipped with rack gear 9, be correspondingly arranged on the track 8 with 9 meshed gears 10 of rack gear, be connected on the gear 10 and turn
Fixed handle 15.By pulling rotational handle 15, gear 10 be moved forward and backward casing 4 can on 11 surface of conduit with carry-over bar 9,
As needed, rotational handle 15 can further include the elastic connection section 12 being arranged in described sleeve pipe 4, institute with several circles of positive and negative rotation
Elastic connection section 12 is stated to be arranged between resilient bladder 5 and rack gear 9.
In the present embodiment, it is equipped with developing ring 13 positioned at the both ends of anchoring balloon 3 on conduit 11, elasticity is located on casing
The both ends of sacculus 5 are equipped with developing ring 14.Developing ring 13 and 14 is specially the platinum ring made of platinum material, technical maturity
Height, development effect is obvious, can accurately determine the position of sacculus, helps doctor that accurately sacculus is positioned in intravascular stent,
Greatly improve the efficiency of operation and the accuracy of intubation.
First the anchoring balloon 3 of 11 front end of conduit is positioned in branch vessel under the guidance of seal wire, visual lower bracket 2
It postpones, anchoring balloon 3 is filled by priming device, the resilient bladder 5 and set of bracket 2 are then coated with according to the accurate adjustment of development
Pipe 4 after reaching designated position, fills resilient bladder 5 by priming device and discharges bracket 2, finally shrink anchoring balloon 3 and elasticity
Sacculus 5, withdraws from support system.Accurate positioning support system of the invention can be accurately positioned release bracket, avoid heart jump
The dynamic influence to backing positions, solve in heartbeat bracket front and back play amplitude be big in the blood vessel, coronary artery bracket can not
Unsatisfied problem is positioned or positioned, success rate of operation is improved.
Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The range of restriction.
