Description

Room corner separator

Technical Field

The invention relates to the technical field of ophthalmic room angle separation equipment, in particular to a room angle separator.

Background

China is the world with the largest glaucoma disease, of which angle-closure glaucoma accounts for the major group (about 350 thousands of people), and is common to patients with chronic angle-closure glaucoma. The atrial-corneal adhesion separation surgery has attracted much attention at home and abroad in recent years, and is considered to be an effective minimally invasive surgery mode for solving chronic angle-closure glaucoma.

Currently, when anterior atrial horn dissection surgery is performed, a proper amount of ophthalmic viscoelastic is generally injected into the anterior atrial horn, and the impact force of the viscoelastic on the anterior atrial horn separates the peripheral iris of anterior synechia from the anterior atrial horn, so that the trabecular meshwork is exposed, and the function of the trabecular meshwork is recovered.

Conventional atrial detacher needles are typically sharp and are used only as a viscoelastic spray, and conventional atrial detachers have a low efficiency of viscoelastic spray, while relying only on ophthalmic viscoelastic to separate the anterior chamber angle insufficiently, and if other structures are used, the structures of the angle are easily damaged during the procedure.

To this end, we propose a room separator.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides the room angle separator which overcomes the defects of the prior art, has reasonable design and compact structure, solves the problem that the needle head of the prior room angle separator is relatively sharp and only has the function of spraying viscoelastic agent, and has limited room angle separation effect.

(II) technical scheme

In order to achieve the purpose, the invention is realized by the following technical scheme:

an atrial separator comprising:

an injector;

a needle connected to the output end of the syringe;

the other end of the needle head is connected with a supporting part;

the supporting part is arranged in an arc shape, so that a room corner is conveniently supported;

the section of the supporting part is a curved surface;

the supporting part is provided with a plurality of spray holes, and the opening directions of the spray holes are arc-shaped.

Furthermore, the needle head is connected with the supporting part through a connecting piece, and the connecting piece is in threaded connection or plug-in connection.

Furthermore, a bevel is arranged on the needle head, and the angle of the bevel is between 100 and 130 degrees.

Furthermore, the curvature radius of the supporting part is 6-10mm, and the length of the supporting part is 2.2-2.6 mm.

Furthermore, both ends of the supporting part are arranged in a round angle mode.

Furthermore, the number of the jet holes is more than or equal to one, and the plurality of jet holes are distributed at equal intervals.

(III) advantageous effects

The embodiment of the invention provides a room separator. The method has the following beneficial effects:

1. the supporting part is matched with the corner in shape, the curvature radius of the supporting part is 6-10mm, the length of the supporting part is 2.2-2.6mm, and the length of the supporting part is slightly smaller than that of the corner, so that the corner can be conveniently attached to and unfolded.

2. The room corner separation effect is improved. The supporting part is adopted to cooperate with the viscoelastic agent sprayed by the injector and the needle head to jointly play a role in separating the room angle.

3. The efficiency of spraying the viscoelastic agent is improved. The supporting part is provided with a plurality of spray holes, and the opening directions of the spray holes are arc-shaped, so that the efficiency of spraying the viscoelastic agent is improved.

4. The supporting part is the curved surface, and the both ends of supporting part are the fillet setting, avoid scotching the room angle tissue, and difficult damage room angle tissue simultaneously, safe and reliable more, the implementation of being convenient for is promoted.

5. The supporting part is convenient to replace, more convenient and sanitary, and the connecting piece is in threaded connection or plug-in connection, so that the supporting part is convenient to replace.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to the attached drawings 1-2, the room corner separator comprises an injector 1, wherein the output end of the injector 1 is connected with a needle head 2, the other end of the needle head 2 is connected with a supporting part 3 through a connecting piece 2.1, a folding angle alpha is arranged on the needle head 2, the angle of the folding angle alpha is between 100 degrees and 130 degrees, the needle head can conveniently extend into the room corner, the supporting part 3 is arranged in an arc shape, the curvature radius of the supporting part 3 is 6-10mm, the length of the supporting part 3 is 2.2-2.6mm and is slightly smaller than the length of the room corner, the room corner is conveniently attached, and the room corner is conveniently opened;

in this embodiment, as shown in fig. 2, the supporting portion 3 is a curved surface, and both ends of the supporting portion 3 are rounded to avoid scratching the tissue of the room corner, the supporting portion 3 is provided with a plurality of nozzle holes b, the opening direction of the nozzle holes b is arc-shaped, the number of the nozzle holes b is greater than or equal to 1, and the nozzle holes b are distributed at equal intervals to prevent the viscoelastic agent from being sprayed too intensively and easily damaging the room corner, and at the same time, prevent the efficiency of spraying the viscoelastic agent from being too low, which results in too long operation time.

The connecting piece 2.1 is in threaded connection or plug-in connection, so that the supporting part 3 is convenient to replace, and the sanitary effect is achieved.
