Exemplary embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, embodiment of the present utility model provides a kind of hyaline cap of inside diameter-variable, wherein variable
The hyaline cap of internal diameter includes hyaline cap body 1 and diameter changing device 2, and the wherein elastically deformable of hyaline cap body 1, diameter changing device 2 is set
Put in the inside of hyaline cap body 1 and fitted with the inwall of hyaline cap body 1, at least one of external diameter of diameter changing device 2
It is adjustable, and then adjust the internal diameter of hyaline cap body 1.
The utility model becomes by setting diameter changing device 2 inside the hyaline cap body 1 of elastically deformable, and by adjusting
Footpath device 2 and then to change the internal diameter of hyaline cap body 1 so that hyaline cap in Minimally Invasive Surgery using more convenient, not more
In the case of changing hyaline cap, by changing the inside diameter of hyaline cap body 1 with regard to hyaline cap can be made to meet the requirement of Minimally Invasive Surgery,
Different size of pathological tissues can be adsorbed, further to be cut off to pathological tissues.
Specifically, as in Figure 3-5, diameter changing device 2 includes elastic support 21 and actuating mechanism 22.
Wherein, elastic support 21 includes the resilient support portion 212 of retainer ring 211 and at least two, and resilient support portion 212 is along admittedly
Determine the circumferential directions of ring 211, the one end of resilient support portion 212 is fixedly connected with retainer ring 211, resilient support portion 212 from
By holding the first end 3 towards hyaline cap body 1 to extend, elastic support 21 be arranged on the inside of hyaline cap body 1 and with hyaline cap sheet
The inwall of body 1 fits；Actuating mechanism 22 is arranged on the inside of elastic support 21, and actuating mechanism 22 includes shift(ing) ring 221 and led
Draw portion 222, shift(ing) ring 221 is arranged on the inside in resilient support portion 212, and the external diameter of shift(ing) ring 221 is more than resilient support portion 212
The minimum diameter of circumference where inner surface, tractive unit 222 are connected with shift(ing) ring 221 and for driving the side vertically of shift(ing) ring 221
To motion.
In the present embodiment, as shown in figure 4, elastic support 21 has certain elasticity, for supporting hyaline cap body 1,
And coordinating actuating mechanism 22 to change the internal diameter of hyaline cap body 1, actuating mechanism 22 in elastic support 21 by moving to change
The motion of bleach cap body 1.Resilient support portion 212 is preferably three, and resilient support portion 212 and retainer ring 211 can lead to
Integrally formed mode is crossed to be formed.The side extension that the free end in resilient support portion 212 changes towards the internal diameter of hyaline cap body 1.Cause
Motivation structure 22 is arranged on the inside of elastic support 21, changes the internal diameter size of hyaline cap body 1 by mobile.
Specifically, elastic support 21 is fixedly installed in hyaline cap body 1, and elastic support 21 can be for example, by：Neck,
Buckle etc. is fixedly installed in hyaline cap body 1, and to avoid in the motion process of actuating mechanism 22, elastic support 21 moves
It is dynamic.
Specifically, the one end of tractive unit 222 is fixedly connected with shift(ing) ring 221, and the free end of tractive unit 222 is towards hyaline cap body
1 the second end 4 extends, and the second end 4 is the opposite end of first end 3.Second end 4 of hyaline cap body 1 is specially hyaline cap sheet
One end that body 1 cooperates with scope.In actual use, scope makes actuating by operating the free end of tractive unit 222
Mechanism 22 can move back and forth along the axial direction of shift(ing) ring 221.
Specifically, second end 4 is at least partly stretched out in the free end of tractive unit 222.In minimal invasive surgical procedures, pass through
Device drawing tractive unit 222 on scope, so that tractive unit 222 drives shift(ing) ring 221 to move, to change hyaline cap body 1
Internal diameter.
As a kind of enforceable mode, the inside of hyaline cap body 1 is provided with detent mechanism 5, and retainer ring 211 passes through localization machine
Structure 5 is fixedly installed in hyaline cap body 1, to prevent the moving influence in the reciprocatory movement of actuating mechanism 22 of elastic support 21
The normal use of hyaline cap body 1.But not limited to this, hyaline cap body 1 can also be according to the elastic deformations of itself, by retainer ring
211 are clamped in hyaline cap body 1.
Specifically, detent mechanism 5 can be the neck or buckle being arranged on the inwall of hyaline cap body 1, by retainer ring
211 are fastened in neck or buckle, but not limited to this, and detent mechanism 5, which can also be other, can realize what retainer ring 211 was fixed
Mechanism.
Specifically, the external diameter of shift(ing) ring 221 is more than the external diameter of retainer ring 211, to ensure shift(ing) ring 221 towards retainer ring
In 211 moving process, shift(ing) ring 221 can continuous dilatational elasticity supporting part 212, enable the internal diameter of hyaline cap body 1 continuous
Increase；When shift(ing) ring 221 is towards in away from the direction moving process of retainer ring 211, resilient support portion 212 is under natural resiliency effect
To contract, simultaneously because hyaline cap body 1 is flexible, so the internal diameter of hyaline cap body 1 can constantly reduce, to reach
Change the purpose of the internal diameter of hyaline cap body 1.
As a kind of enforceable mode, tractive unit 222 at least two, the external diameter that tractive unit 222 is formed be less than or
Equal to the internal diameter of retainer ring 211.As shown in Figure 3 and Figure 5, the present embodiment tractive unit 222 is preferably three, three tractive units
222 external diameters surrounded are less than or equal to the internal diameter of retainer ring 211, so that tractive unit 222 can pass through retainer ring 211, with
Tethered sliding ring 221 simultaneously moves back and forth along the axial direction of shift(ing) ring 221.
As a kind of enforceable mode, hyaline cap body 1 includes insertion section 6 and front end 7, before diameter changing device 2 is arranged on
Inside end 7.Wherein insertion section 6 is used to hyaline cap body 1 being inserted into scope, and inserted mode can be by hyaline cap body 1
The internal diameter of insertion section 6 be arranged to the form of the external diameter for being slightly less than scope, front end 7 is used for the internal diameter for changing hyaline cap body 1, with
Pathological tissues are adsorbed, wherein the insertion section 6 is located at the second end 4, the front end 7 is located at first end 3.
Preferably, drive mechanism (not shown), the drive mechanism and the phase of tractive unit 222 are additionally provided with scope
Connection, for driving the relative transparent cap body 1 of tractive unit 222 to move in the axial direction.
The utility model becomes by setting diameter changing device 2 inside the hyaline cap body 1 of elastically deformable, and by adjusting
Footpath device 2 and then to change the internal diameter of hyaline cap body 1 so that hyaline cap in Minimally Invasive Surgery using more convenient, not more
In the case of changing hyaline cap, by changing the inside diameter of hyaline cap body 1 with regard to hyaline cap can be made to meet the requirement of Minimally Invasive Surgery,
Different size of pathological tissues can be adsorbed, further to be cut off to pathological tissues.
It is described above, the only embodiment of the utility model embodiment, but the protection of the utility model embodiment
Scope is not limited thereto, the technical scope that any one skilled in the art discloses in the utility model embodiment
