Background
Macular hole refers to the defect of tissue from the limiting membrane to the photoreceptor cell layer in the retina of the macula, which seriously damages the central vision of the patient. At present, the treatment is generally carried out by adopting 23G or 25G minimally invasive vitreous cutting operation. For patients who have developed a full-thickness macular hole, the surgical goals are manifold, including relief of vitreous macular stretch, peeling of the anterior macular or retinal limiting membrane associated with the onset of the macular hole, intraocular gas tamponade to close the macular hole, and the like. For refractory macular holes (e.g., macropores or recurrent holes), application of autologous serum, β 2 transforming growth factor (TGF- β 2), or autologous concentrated platelets to the macular hole may increase choroidal retinal adhesion in the region of the hole, promoting closed healing of the hole.

In order to achieve the above object, the present invention provides a retinal massager for minimally invasive vitrectomy, comprising: the massager comprises a massager body, a massaging head and a handle, wherein one end of the massager body is connected with the massaging head, and the other end of the massager body is connected with the handle; wherein, the massage head is in a smooth arc shape, and the diameter of the massage head is 0.5 mm-0.7 mm; the massager body is in a strip shape, and the diameter of the massager body is 0.5 mm-0.7 mm.
Preferably, the massage head is in a smooth spherical shape.
Preferably, the massager further comprises: the transition part is used for connecting the massage heads and arranged between the massage heads and the massager body, and the diameter of the transition part is smaller than that of the massage heads.
Preferably, the diameter of the transition part is smaller than that of the massager body.
Preferably, the massager body, the transition portion and the massage head are connected and arranged through integral forming.
Preferably, the massager body is needle-shaped or thin rod-shaped.
Preferably, the massager body is a rigid thin metal rod.
Preferably, the diameter of the massage head is equal to that of the massager body.
The utility model provides a retina massager for minimal access vitreous body cutting operation, its massager body are thin strip, and the massage head is smooth arc, can get into the eyeball through the sclera puncture, carries out gentle massage to the retina around the macular hole in the art, improves the closed rate of macular hole postoperative effectively. In particular, the massager can also dip medicines promoting the closing of macular holes and assist the medicine absorption through massage.

Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be a mechanical connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The applicant finds that in the process of the vitrectomy surgery, the retina around the macular hole is gently massaged after the inner limiting membrane is removed, so that the closing rate after the macular hole surgery can be effectively improved. However, there is no surgical instrument specially used for massaging retina at present, and the retina is massaged by the vitreous body cutting head or the whistle needle head, which is easy to scratch the retina and has a great risk. Therefore, the utility model designs a retina massager for minimally invasive vitreous cutting operation, which can massage the retina in the operation.
As shown in fig. 1, a retinal massager for minimally invasive vitrectomy surgery comprises: the massager comprises a massager body 10, a massage head 20 and a handle 30, wherein one end of the massager body 10 is connected with the massage head 20, and the other end is connected with the handle 30; wherein, the massage head 20 is in a smooth arc shape, and the diameter thereof is 0.5mm to 0.7 mm; the massager body 10 is in a strip shape, and the diameter of the massager body is 0.5 mm-0.7 mm.
In some embodiments, the massage heads are smooth and spherical.
As shown in fig. 2, in order that the massage head 20 can more conveniently contact the retina when operated obliquely, and has a larger operation space, the massage apparatus further comprises: a transition part 40 for connecting the massage heads, which is arranged between the massage head 20 and the massager body 10, wherein the diameter of the transition part 40 is smaller than that of the massage head 20. Preferably, the transition portion 40 has a diameter smaller than the diameter of the massager body 10.
In some embodiments, the massager body 10, the transition portion 40 and the massage head 20 are connected by an integral molding, such as a metal massager body, a transition portion and a massage head made by a mold or 3D printing.
In some embodiments, the massager body 10 is in the shape of a needle or a thin rod.
Because each component in the eyeball, particularly the retina, is tender and fragile, the massager body preferably adopts a rigid thin metal rod to avoid the risk of easily scratching the retina.
When the diameter of the massage head is larger than that of the massager body, the massager body (slender rod) cannot be closed with the puncture hole after passing through the sclera puncture hole, and water leakage in an operation can be caused. In some embodiments, the diameter of the massage head is equal to the diameter of the massager body.
The handle 30 is a conventional portable handle, and is convenient to hold and operate.
In some embodiments, the massage head 20 has a diameter of 0.63mm (about 23G) and can pass through a 23G scleral puncture.
In some embodiments, the massage head 20 has a diameter of 0.53mm (about 25G) and can pass through a 25G scleral puncture.
In some embodiments, the massage head 20 can also dip the post-operative drugs beneficial to macular hole, and the post-operative closure can be promoted by applying the massage to enhance the absorption.
To sum up, the utility model provides a pair of a retina massager for minimal access vitreous body cutting operation, the massager body is thin strip, and the massage head is smooth arc, can get into the eyeball through the sclera puncture, carries out gentle massage to the retina in the art, improves the closure rate of macular hole postoperative effectively.
While the present invention has been described in detail with reference to the preferred embodiments thereof, it should be understood that the above description should not be taken as limiting the present invention. Numerous modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the foregoing description. Accordingly, the scope of the invention should be limited only by the attached claims.
