Description
Technical field
This utility model relates to medical instruments field, particularly a kind of ophthalmologic operation drag hook of the upper and lower eyelid that retracts patient in ophthalmic surgical procedures and ophthalmologic operation drag hook group.
Background technology
At present on clinical medicine, when ophthalmology is performed the operation, often need to retract upper and lower eyelid tissue, expose eyeball, palpebral conjunctiva etc., while being convenient to perform the operation, detect and operate, in technology in the past, need assistant to go to pull open the very bothersome effort of eyelid with artificial both hands, or, use a kind ofly open at a certain angle, closed retractor removes to retract upper and lower eyelid, expose eyeball, this leicht fallen D/A that compares comparatively speaking.
But, for the position that eyes are different, carry out ophthalmologic operation, accordingly, the required just difference of position that especially expands surgical field of view, for example, for eyelid, lachrymal sac, iris periphery, the situations such as trichiasis are got off and are retracted, the shape requirement of the surgical field of view presenting after palpebra inferior is also different, existingly open at a certain angle, closed retractor cannot be tackled flexibly traction according to the difference of eye locations in ophthalmologic operation at all and be pulled open the optimum surgical field of view form of formation, particularly, when operation is carried out, after the intention of operator changes, in the time of need to adjusting the position of drag hook and angle, this fixed retractor must be all takes off changing angle and installs from circumference of eyes, very inconvenient.In addition, use artificial both hands or hand-held drag hook, although can adjust in time the position, angle of drag hook etc., expended several assistants, increase labor intensity, ophthalmologic operation working place is originally just very narrow and small, between assistant and operative doctor, row station difficulty, keeps out mutually obstruction, very easily produces the situation about overexerting of pullling, not only cannot adjust flexibly drag hook position, visual field area and also cannot guarantee the soft of drawing-in motion, bring unnecessary injury to the soft tender and lovely eyelid skin of patient.
So, in existing technology, lack and a kind ofly can draw the ophthalmologic operation drag hook that forms the different surgical field of view forms that adapt according to the difference of the eye locations of required operation.
Utility model content
The purpose of this utility model is to provide a kind of can draw the ophthalmologic operation drag hook and the ophthalmologic operation drag hook group that form the different surgical field of view forms that adapt according to the difference of the eye locations of required operation.
The ophthalmologic operation drag hook of a kind of eyelid that retracts patient in ophthalmic surgical procedures that this utility model provides, has such feature, comprising: pawl head, for pulling open eyelid; Positioning head, for being fixed on patient's the fixing article of facial periphery; And be connected to the rope body between pawl head and positioning head.
In ophthalmologic operation drag hook of the present utility model, can also there is such feature: wherein, pawl head is have the crotch of atraumatic end face and retract any one in pawl.
In ophthalmologic operation drag hook of the present utility model, can also there is such feature: wherein, positioning head is any one in clip and claw.
In ophthalmologic operation drag hook of the present utility model, can also there is such feature: wherein, any one in small hose and elastic threads that rope body is random-shaping.
In addition, this utility model also provides a kind of ophthalmologic operation drag hook group of the eyelid that retracts patient in ophthalmic surgical procedures, there is such feature: at least one ophthalmologic operation drag hook, with patient's a pair of upper eyelid and the corresponding setting of palpebra inferior, wherein, ophthalmologic operation drag hook is the ophthalmologic operation drag hook in above-mentioned any one.
The effect of utility model:
According to the related ophthalmologic operation drag hook of this utility model, can in ophthalmic surgical procedures, retract patient's upper or palpebra inferior, expose surgical field of view, on, palpebra inferior needs at least two ophthalmologic operation drag hooks to pull open respectively, because the pawl head of each ophthalmologic operation drag hook pulls open upper eyelid or palpebra inferior, positioning head by the other end in each ophthalmologic operation drag hook of connection of rope body has just been fixed on patient's the fixing article of facial periphery, these fixing article can be the face shield that covers on patient's face, pillow is put the surgical drage of patient head or fixed rod frame etc., thereby, the difference of the eye locations of required operation, correspondingly can varying number be set to same upper eyelid or palpebra inferior, the ophthalmologic operation drag hook of different angles draws and forms the different surgical field of view forms that adapt, even the intention of operator has changed in the middle of the process of operation, the ophthalmologic operation drag hook group being formed by many ophthalmologic operation drag hooks is without all taking off changing angle and install from circumference of eyes, only need to adjust the wherein position angle of some ophthalmologic operation drag hooks, very convenient, do not affect operation process.Therefore, this utility model can provide a kind of and can draw the ophthalmologic operation drag hook and the ophthalmologic operation drag hook group that form the different surgical field of view forms that adapt according to the difference of the eye locations of required operation.
