Abstract
The utility model discloses a kind of Vitrectomy corneal contact lens fixture, it comprises eye speculum and microscope base; Eye speculum has two to be left eyelid hook, is connected to the two transverse arm portions opening the expanded support arm on rear side of eyelid hook and be connected by two expanded support arm tail ends; The tail end of two expanded support arms is rolled over from upper side direction back bending, and transverse arm portion is positioned at back upper place that two drive eyelid hook; Transverse arm portion is provided with a rotary sleeve, and this rotary sleeve is cranked arm through one and is connected with a circular microscope base, and microscope base is positioned at the top that two drive eyelid hook; Rotary sleeve is provided with one for locking the set screw of itself and transverse arm portion relative position.It, without the need to by sewing up, can not cause damage to patient's eyeball, reducing postoperative complication risk, decrease operating time, and good fixing effect.Due to by carrying out rotary sleeve regulating the position that can control microscope base, being more conducive to guaranteeing that microscope base is fixed on appropriate position, ensureing the contact effect of contact lens and cornea.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of Vitrectomy corneal contact lens fixture.
Background technology
Corneal contact lens is operating theater instruments indispensable in Liquid Perflurocarbon, and it is in Vitrectomy, utilizes other fixture immobilizing corneal surface.Conventional corneal contact lens retainer ring fixes contact lens at present, this retainer ring has two batters, utilize in operation suture by batter through suture of conjunctiva in scleral surface, thus reach the object of fixing contact lens, the weak point of this operation is: in (1) operation, corneal contact lens retainer ring being sewn to scleral surface needs to spend certain hour, operating time extends, and there is infection risk; (2) stitching can cause certain damage, as subconjunctival hemorrhage, perforation of eyeball etc. to eye's tissue; (3) commissural sutures easily comes off repeatedly, and fixed effect is not good enough.
Publication number a kind of corneal contact lens fixture that has been the disclosure of the invention of CN 102935025A, it is made up of eye speculum tool and retainer ring, eye speculum tool has two and drives eyelid hook, retainer ring is arranged with two batters, two side legs and two is driven eyelid hook and is connected through connecting band, because the support arm of eye speculum tool is generally within same plane, is not easy in operation extrude, easily to be hit by a bullet cunning from hands before driving eyelid hook and being placed into eyelid, to install difficulty large; Due to retainer ring with drive eyelid hook and be connected through connecting band, both relative positions cannot arbitrarily regulate, and cannot ensure that retainer ring is in correct position, and then cannot ensure the contact effect of corneal contact lens and patient's cornea; Because some connecting bands are distributed in the outside of retainer ring, hinder the carrying out of operation technique.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, installs conveniently, fix, thus wound is less without the need to retainer ring being carried out stitching, and fixing comparatively firm Vitrectomy corneal contact lens fixture.
For realizing above-mentioned technical purpose, this utility model adopts following technical scheme: a kind of Vitrectomy corneal contact lens fixture, comprises eye speculum and microscope base; Described eye speculum is bent by an one metal wire and forms, and has two to drive eyelid hook, be connected to the two transverse arm portions opening the expanded support arm on rear side of eyelid hook and be connected by two expanded support arm tail ends, its entirety symmetrically structure; It is characterized in that: the tail end of two described expanded support arms is rolled over from upper side direction back bending, and transverse arm portion is positioned at back upper place that two drive eyelid hook; Described transverse arm portion is provided with a rotary sleeve, and this rotary sleeve is cranked arm through one and is connected with a circular microscope base, and described microscope base is positioned at the top that two drive eyelid hook; Described rotary sleeve is provided with one for locking the set screw of itself and transverse arm portion relative position.
This utility model has following beneficial effect: it is without the need to making to be fixed on epibulbar object by sewing up just can reach, damage can not be caused to patient's eyeball, reduce postoperative complication risk, as long as adopt eye speculum directly to strut the eyelid of patient in operation, greatly reduce operating time, and good fixing effect.Two expanded support arms respectively have an inflection structure, make two expanded support arms not be arranged in single plane, are more convenient to holding operation; Due to by regulating rotary sleeve, the position of microscope base can be controlled, being more conducive to guaranteeing that microscope base is fixed on appropriate position, ensure the contact effect of contact lens and cornea.

Detailed description of the invention
Accompanying drawings 1,2, a kind of Vitrectomy corneal contact lens fixture disclosed in this utility model, it comprises eye speculum and microscope base 4; Described eye speculum is bent by an one metal wire and forms, and has two to drive eyelid hook 6, be connected to the two transverse arm portions 3 opening the expanded support arm 7 on rear side of eyelid hook 6 and be connected by two expanded support arm 7 tail ends, its entirety symmetrically structure; It is characterized in that: the tail end of two described expanded support arms 7 is rolled over from upper side direction back bending, and transverse arm portion 3 is positioned at back upper place that two drive eyelid hook 6; Described transverse arm portion 3 is provided with a rotary sleeve 2, and this rotary sleeve 2 is cranked arm through one and 5 is connected with a circular microscope base 4, and described microscope base 4 is positioned at the top that two drive eyelid hook 6; Described rotary sleeve 2 is provided with one for locking the set screw 1 of itself and transverse arm portion 3 relative position.
It is without the need to making to be fixed on epibulbar object by sewing up just can reach, damage can not be caused to patient's eyeball, reduce postoperative complication risk, as long as adopt eye speculum directly to strut the eyelid of patient in operation, greatly reduce operating time, and good fixing effect.Two expanded support arms 7 respectively have an inflection structure, make two expanded support arms 7 not be arranged in single plane, are more convenient to holding operation; Due to by regulating rotary sleeve 2, the position of microscope base can be controlled, be more conducive to guaranteeing that microscope base 4 is fixed on appropriate position, ensure the contact effect of contact lens and cornea.
