Description
Technical Field
The utility model belongs to the technical field of medical appliances, and relates to a multifunctional auxiliary hook for anterior ocular segment.
Background
The angle between cornea and iris is called anterior chamber angle, which is composed of anterior and posterior walls and the recess between the two walls. Anterior chamber angle is the pathway for aqueous humor outflow, and if a part or even all of the anterior iris adhesions or the aqueous humor adhesions are caused by various reasons, the aqueous humor is closed, aqueous humor outflow is blocked, and intraocular pressure is raised, thereby causing the occurrence of angle-closure glaucoma.
Glaucoma treatment is classified into medicine, laser and surgery, all aimed at lowering intraocular pressure. Trabeculectomy has been the traditional choice for anti-glaucoma, but there are still a significant proportion of patients after surgery who have had poor, ineffective or excessive ocular pressure drop resulting in low ocular pressure and complications such as exacerbation of cataract. In recent years, with the continuous deep understanding of the structures of the atrial corners, the adhered atrial corners can be recovered after separation, so that the intraocular pressure is reduced, and cataract operation combined atrial corner separation has become one of the main operation modes for treating glaucoma, so that the tool for separating the atrial corners can help the separation of the adhered atrial corners.
Defects of large pupils and irises after various ocular trauma, intraocular surgery and partial glaucoma attacks can cause photophobia, blurred vision and visual disturbance to patients, and iris suturing and pupil formation operations are required.
Residual anterior capsule and equatorial cortex and lens epithelial cells are removed as much as possible in cataract surgery, and occurrence of posterior cataract, postoperative anterior capsule opacification and capsular contraction can be reduced.
Disclosure of Invention
The utility model aims to provide a multifunctional auxiliary hook for anterior ocular segment.
The aim of the utility model can be achieved by the following technical scheme:
a multifunctional auxiliary hook for the anterior ocular segment comprises a hand-held handle, a bending rod arranged at the end part of the hand-held handle, and a front-end lantern ring arranged at the end part of the bending rod.
Further, the bending rod comprises an extending straight rod with the end part connected with the hand-held handle and a bending rod connected with the other end of the extending straight rod;
an included angle of 120-160 degrees is formed between the extending straight rod and the bending rod.
Further, an included angle of 150 degrees is formed between the extending straight rod and the bending rod.
Further, the front end lantern ring is an elliptical lantern ring.
Further, the length of the long shaft of the outer ring of the elliptical lantern ring is 2-4mm, and the length of the short shaft is 0.7-1.0mm; the length of the long shaft of the inner ring is 0.8-1.2mm, and the length of the short shaft is 0.2-0.6mm.
Further, the thickness of the elliptical lantern ring is 0.1-0.3mm.
Further, the length of the long shaft of the outer ring of the elliptical lantern ring is 3mm, and the length of the short shaft is 0.8mm; the long axis of the inner ring is 1.0mm, and the short axis is 0.4mm.
Further, the thickness of the elliptical lantern ring is 0.2mm.
Further, the surface of the elliptical lantern ring is made into a frosted shape.
Further, an anti-slip ring groove is formed in the hand-held handle.
Further, a plurality of anti-slip ring grooves are formed in the handheld handle, and the anti-slip ring grooves are arranged at equal intervals.
Compared with the prior art, the utility model has the following characteristics:
when the iris is partially and completely adhered, the pupil can not be enlarged, the visual area and the operable area of cataract surgery are limited, the risk of the surgery is increased, complications such as corneal endothelial injury, posterior capsule rupture, crystalline nucleus falling into vitreous body, crystalline lens cortex residue and the like are caused, and the postoperative response is increased. Tools are required to separate the post-iris adhesions from point to face.
The instruments used at present for separating the atrial angle mainly comprise capsulorhexis forceps and a separator, wherein one is the capsulorhexis forceps which are conventionally used in cataract extraction, and the other is the separator for passively separating the peripheral iris from the atrial angle. The capsulorhexis forceps in cataract operation are mainly used for separating peripheral irises from trabecular meshwork by pinching irises and pulling the irises towards the center of pupils, so that the irises and the pupillary dilated muscles are easily damaged, and meanwhile, obvious pain is brought to patients. The separator has single function, and some separators cannot passively separate trabecular meshwork distributed at 360 degrees because of limited operation angles, so that the intraocular pressure reducing effect is limited due to the limitation of a separation structure.
The utility model well makes up the defects of the traditional instrument, has various functions, and firstly, the operating head of the device is an elliptical lantern ring, the surface of the ring is rough, and when the iris is pressed by adhesion, the iris can be pulled to the center of the pupil by friction force due to the large friction force; and secondly, the transverse aperture is shorter, and the separator can be accessed into eyes through a side incision in cataract surgery, so that the problem of insufficient operation angle of the separator is solved well.
Compared with the prior device CN216798001U, the utility model increases the function of pulling the iris suture, and the oval lantern ring at the front end can improve the problems of difficult iris suture stress and easy iris contusion, and can more efficiently finish the iris suture by guiding the iris suture to pass through the hole.
