Description
Technical field
The utility model is related to the skin used in a kind of medicine equipment, more particularly to orthopaedics and other Minimally Invasive Surgeries and strutted
Device.
Background technology
Dilator is essential operating theater instruments in many surgical operations, and its is simple to operate, can save manpower and
Operating space, thus enjoy surgeon to favor.But in hand surgical operation, especially microsurgery, still not compared with
For suitable dilator.There is a kind of elastic wire dilator in clinical position, be closer to hand surgical procedures needs, but its
Drag hook part for strutting is fixed from activity, it is impossible to art is more fully exposed under conditions of operative incision length is certain
It is wild.
Utility model content
The purpose of this utility model is to be improved and innovated that there is provided one for shortcoming present in background technology and problem
Visual area can be adjusted so that visual area exposes more fully movable drag hook skin dilator at any time as needed by planting.
The technical solution of the utility model is to construct a kind of movable drag hook skin dilator, including two drag hooks, two
Arm, an elastic force ring are strutted, the elastic force ring includes the pin of the variable-angle of two stretchings, described two one end for strutting arm
Two pins of elastic force ring are connected respectively, and the other end connects a drag hook respectively, wherein：The drag hook passes through activity with strutting arm
Joint is connected.
In one of the embodiments, described to strut arm and elastic force ring is structure as a whole, the arm that struts is the bullet
The elongated portion of the pin of power ring.
In one of the embodiments, the turning joint is tubular rivet, and the tubular rivet is fixed on the drag hook
On, the hollow part for strutting arm bending and inserting the rivet, and be in close contact but do not fix with tubular rivet.
In one of the embodiments, the inner side of two drag hooks has radian.
Advantage and beneficial effect of the present utility model：
The utility model is simple in construction, easy to use.In use, pinching two struts arm, movable drag hook skin is supportted
Drive device and extrude to certain angle and be placed in visual area, both sides movable hook is placed in the subcutaneous appropriate location in visual area both sides, and release struts arm i.e.
Can.Drag hook can make when strutting and according to soft tissue situation the adjustment in angle after strutting, and preferably expose surgical field of view, side
Just operation technique.
Brief description of the drawings
Fig. 1 is the overall structure diagram of embodiment.
Fig. 2 is connection diagram of the drag hook with strutting arm in embodiment.
Embodiment
For the ease of understanding the utility model, the utility model is more fully retouched below with reference to relevant drawings
State.Preferred embodiment of the present utility model is given in accompanying drawing.But, the utility model can come real in many different forms

The implication that is generally understood that of technical staff it is identical.Term used in the description is intended merely to describe specifically to implement purpose,
It is not intended to limit the utility model.
Embodiment 1
As shown in figure 1, a kind of movable drag hook skin dilator, including two drag hooks 1, two strut arm 2, an elastic force
Ring 3, the elastic force ring 3 includes the pin of the variable-angle of two stretchings, and described two one end for strutting arm 2 connect elastic force respectively
Two pins of ring 3, the other end connects a drag hook 1 respectively.
As shown in Fig. 2 the drag hook 1 is connected with strutting arm 2 by tubular rivet 4, it is described to strut the bending of arm 2 and insert institute
The hollow part of tubular rivet 4 is stated, and is in close contact but does not fix with tubular rivet 4, the drag hook 1 can be rotated with external force,
By the drag hook 1 and strut the angle between arm 2 and be adjusted.
Embodiment 2
Compared with Example 1, described in the present embodiment strut arm 2 and elastic force ring 3 is structure as a whole, i.e., it is described to strut arm
2 be the elongated portion of the pin of the elastic force ring 3, while the inner side of two drag hooks 1 has radian, can be avoided to tissue
Incised wound.
Operation principle of the present utility model is：In use, pinching two struts arm, movable drag hook skin dilator is squeezed
It is depressed into certain angle and is placed in visual area, both sides movable hook is placed in the subcutaneous appropriate location in visual area both sides, and release struts arm.Drag hook
The adjustment in angle can be made when strutting and according to soft tissue situation after strutting, preferably expose surgical field of view, convenient operation
Operation.
Embodiment described in the utility model is only the description carried out to preferred embodiment of the present utility model, not
The utility model spirit and scope are defined, on the premise of the utility model design philosophy is not departed from, work in this area
