Integral structure can also be made in hook part 11 provided in this embodiment, to adapt to different users, can make not
The drag hook ontology 1 of same specification.
It, can be by hook part 11, the when the first segmental arc 111, the second segmental arc 112 and linkage section 113 support integral structure
Integral structure is also made in one interconnecting piece 12 and second connecting portion 13, i.e. drag hook ontology 1 is structure as a whole, as shown in Figure 2.One knot
Structure keeps drag hook ontology 1 not easy to break, long service life.It, can be with to adapt to not have to user because everyone eyelid size is different
The drag hook ontology 1 of different size is made, when being performed the operation, doctor selects drag hook ontology 1 according to the concrete condition of user
Specification.
In the optinal plan of the present embodiment, more preferably,
As shown in Fig. 2, eyelid retractor further includes traction piece 3, traction piece 3 is connected to the free end of drawstring 2.
It is solid by the traction piece 3 of 2 free end of drawstring after hook part 11 is protruded into eyelid and drawstring 2 is pulled to pull open eyelid
Due on the clothes or hospital bed of patient, eyelid is made to be constantly in the state of being opened.
Traction piece 3 is safety pin.
In use, safety pin is directly made disease not in the clothes of patient after doctor pulls drawstring 2 to pull open the eyelid of patient
The eyelid of people is constantly in open configuration in the course of surgery.
It should be noted that traction piece 3 can also be other structures form in addition to using this structure type of safety pin, lift
Under such as:
Traction piece 3 can be clip, in use, directly pressing from both sides clip after doctor pulls drawstring 2 to pull open the eyelid of patient
On the clothes of patient or on hospital bed, the eyelid of patient is made to be constantly in open configuration in the course of surgery.
Traction piece 3 can also be sucker, in use, after doctor pulls drawstring 2 to pull open the eyelid of patient, directly by sucker
It is adsorbed on hospital bed, the eyelid of patient is made to be constantly in open configuration in the course of surgery.
In the optinal plan of the present embodiment, more preferably,
First connecting portion 12 and second connecting portion 13 are arc structure, and first connecting portion 12 and second connecting portion 13 are convex
To hook part 11.
In specific implementation process, compared to straight-line mechanism, first connecting portion 12 and second connecting portion 13 are designed as arcuation
Structure can reduce the contact area of first connecting portion 12 and second connecting portion 13 and human skin, and then reduce first connecting portion
12 and friction of the second connecting portion 13 to skin, mitigate the sense of discomfort of human body.
It should be noted that first connecting portion 12 and second connecting portion 13, in addition to using above-mentioned arc structure, first connects
Portion 12 and second connecting portion 13 can also use other structures form, be exemplified below:
First connecting portion 12 and second connecting portion 13 can be linear structure, due to linear structure and human skin contact surface
Product is larger, has larger friction to human skin, can connect in the side that first connecting portion 12 is contacted with human skin and second
The side that portion 13 is contacted with human skin is respectively provided with layer of silica gel.
First connecting portion 12 and second connecting portion 13 can also be that ripple type structure, ripple type structure can also reduce first
The contact area of interconnecting piece 12 and second connecting portion 13 and human body, still, linear structure and arc structure, ripple type structure add
Work difficulty is big, and processing cost is high.
In the optinal plan of the present embodiment, more preferably,
The material of drag hook ontology 1 is copper.
It should be noted that the material of drag hook ontology 1 in addition to using copper, can also use other materials, be exemplified below:
The material of drag hook ontology 1 can also use titanium, and titanium is close biological metal, will not generate wound to human body with human contact
Evil.
Drag hook ontology 1 can also be using ceramics, and ceramics are harmless, and surface is smooth.
Drag hook ontology 1 can also use steel, and steel are relatively inexpensive.
In specific implementation process, due to drag hook ontology 1 and direct body contact, compared with steel material, copper material compared with
It is soft, while it being able to suppress bacterial reproduction, reduce a possibility that eyelid infects.With titanium and ceramic phase ratio, copper material is relatively inexpensive, reduces
The manufacture difficulty of drag hook ontology 1, meanwhile, it is easy to be widely used.
Drawstring 2 can be made of metallic fiber, can also be at this point, drawstring 2 can be welded in the tail portion of drag hook ontology 1
Drawstring 2 is pasted on to the tail portion of drag hook ontology 1 using adhesive tape；Drawstring 2 can also be nylon rope, at this point it is possible to will using adhesive tape
Drawstring 2 is pasted on the tail portion of drag hook ontology 1, and drawstring 2 can also be lain in the tail portion of drag hook ontology 1.
It should be noted that the present embodiment does not limit the material of drawstring 2, as long as the material of soft flexible
?.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should manage
Solution: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of skills
Art feature is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution the utility model
The range of each embodiment technical solution.
