Description
Technical field
The invention belongs to perform the operation to use the field of medical instrument technology, and in particular to a kind of operative incision quickly supports stent.
Background technology
Surgeon is typically necessary when performing an operation and struts the notch skin of patient to widen the vision, at this time It needs to use dilator.At present, the dilator clinically used, structure is more complicated, and cost is more expensive, and operates also inconvenience, It is typically necessary two medical staff while operates, therefore not only extend operating time, be greatly reduced operation effect Rate.
The content of the invention
Problem and shortage existing for the existing dilator of pin of the present invention provides a kind of easy to operate and to strut degree controllable Operative incision quickly supports stent.
The technical solution adopted by the present invention：A kind of operative incision quickly supports stent, including at least three groups by casing and set The external member of bar mutual sheathing composition, each group external member are fixed together to form cyclic structure from beginning to end successively；In the casing of each external member The inside or outside of root and loop bar root are fixed with transverse pin axle, and swing rod, the end of each pair swing rod are hinged on each transverse pin axle End is hinged by middle axis pin, while pressing handle is hinged on middle axis pin；In the ferrule boot of each external member Support chip is fixed with below loop bar root；Be provided with overturning block machine on the upside of each pair swing rod, when two swing rods to The angle of lower swing is supported on the upside of two swing rods more than overturning block machine after 180 degree, is crossed.
Locking pin is installed with loop bar link position in the casing of every group of external member.
Each swing rod sheet as can dilatability sleeve structure, and suit position set locking member.
The position that each loop bar is located at middle axis pin is provided with bar hole, and middle axis pin is located in bar hole, and the one of middle axis pin Side is provided with locking pin.
It is connected between each pair swing rod and keeps tension spring of two swing rods to contract.
Beneficial effects of the present invention：The present invention can realize the advantages of rapid deployment stent, and each external member has Telescopic, Stent can be kept to be in smaller loop configuration under indentation state, can keep stent larger in the deployed state Loop configuration, so as to strut wound periphery using multiple support chips on the downside of stent.The present invention by press handle come Each pair swing rod is driven, can easily drive the stretching motion of every group of external member, simple in structure, easy to operate, using effect is good.
The present invention can also realize that the contraction that bigger is divided into is adjusted, use scope is more by way of controlling oscillating bar length Extensively.
The present invention can keep each pair swing rod inwardly in contraction state, during pressing swing rod, tension spring using tension spring It is first stretched and then shrinks again, after pressing makes two swing rods be more than 180 degree, under the pulling force effect of tension spring, two swing rods are still In stable open configuration.

Specific embodiment
Embodiment 1：Operative incision as shown in Figure 1 quickly supports stent, and one is fixed on from beginning to end successively including four groups of external members It rises and forms cyclic structure.Also ring assembling structure can be formed with six groups of external members or other quantity external member.
Every group of external member is all made of casing 1 and 2 mutual sheathing of loop bar, and the suit each external member in rear end can freely stretch.Work as exhibition After opening each external member, larger cyclic structure can be formed, after each external member is compressed, smaller cyclic structure can be formed.
In the inside of 2 root of 1 root of casing and loop bar of each external member（It is or outer）Side is fixed with transverse pin axle 4, each horizontal Axle sleeve 5 is set on axis pin 4, swing rod 6 is vertically welded on each axle sleeve 5.The end of same external member upper end a pair of swing rod 6 passes through Middle axis pin 7 is hinged.Pressing handle 8 is hinged on middle axis pin 7 simultaneously.Each pair swing rod is driven by pressing handle 8 6, the stretching motion of every group of external member can be easily driven, simple in structure, easy to operate, using effect is good.
Support chip 3 is fixed with below 2 root of 1 root of casing and loop bar of each external member.It can utilize on the downside of stent Multiple support chips 3 strut wound periphery.As shown in Fig. 2, support chip 3 is finally arc.
As shown in figure 3, be provided with overturning block machine 9 in the upside of each pair swing rod 6, when two swing rods 6 are to the angle of lower swing After 180 degree, cross and overturn the upside that block machine 9 is supported on two swing rods 6.
Embodiment 2：Lock is installed with 2 link position of loop bar on the basis of embodiment 1, and in the casing 1 of every group of external member Tight pin 12.Can only there are maximum opening and minimum aperture both of which compared with embodiment 1, the present embodiment is by setting locking pin 12 It can realize the control and locking of any opening degree in limited range.
Embodiment 3：On the basis of embodiment 1 or embodiment 2, each swing rod 6 is designed to be able to dilatability suit in itself Structure, and locking member is set at suit position.By way of controlling 6 length of swing rod, realize that the contraction that bigger is divided into is adjusted, make It is wider with scope.
Embodiment 4：On the basis of embodiment 1 or embodiment 2, participate in shown in Fig. 4, be located at middle axis pin 7 in each loop bar 2 Position is provided with bar hole 11, and middle axis pin 7 is located in bar hole 11, and the one side of middle axis pin 7 is provided with locking pin 12.
Embodiment 5：It is shown in Figure 5 on the basis of embodiment 1 or embodiment 2, it is connected between each pair swing rod 6 Keep tension spring 10 of two swing rods 6 to contract.It can keep each pair swing rod 6 inwardly in contraction state, pressing using tension spring 10 During swing rod 6, tension spring 10 is first stretched and then shrinks again, after pressing makes two swing rods 6 be more than 180 degree, in tension spring 10 Pulling force effect under, two swing rods 6 are still within stable open configuration.
