Description

Anterior chamber maintenance and positioning device for ICL implantation surgery

Technical Field

The utility model relates to the technical field of ophthalmic surgical instruments, in particular to an anterior chamber maintaining and positioning device for ICL implantation operation.

Background

ICL is a short term for intraocular lens implantation of the posterior chamber of the eye with a lens, a new technique for refractive correction, and is now widely used globally. It can be used to correct a wide range of myopia, hyperopia and astigmatism without the need to remove or destroy corneal tissue, without the need to perform surgical sutures and is particularly effective in the treatment of high myopia. The anterior chamber maintenance is an important premise that the ICL operation can be safely and smoothly carried out, the viscoelastic agent needs to be filled in the anterior chamber for maintaining the anterior chamber in the traditional method, and the viscoelastic agent is cleaned after the operation is finished. But on the one hand, the operation steps are increased, and the operation time is prolonged; on the other hand, viscoelastic agents are not easy to clean and are easy to cause complications such as postoperative acute ocular hypertension.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects existing in the prior art, the utility model provides an anterior chamber maintaining and positioning device for ICL implantation operation, which has the following specific scheme:

the infusion needle is connected with an infusion handle, and a cavity communicated with the infusion needle is formed in the infusion handle; the tail end of the infusion handle is provided with a water inlet hole communicated with the inner cavity, and the water inlet hole is connected with an infusion bottle through a conduit; the infusion bottle is internally provided with perfusion fluid, and the height of the infusion bottle is greater than the working height of the infusion needle head when the infusion bottle is used; the infusion needle is sleeved with a needle sleeve.

Furthermore, a needle sleeve matched with the infusion needle is sleeved outside the infusion needle, the length of the needle sleeve is smaller than that of the infusion needle, a closed-up shape is formed at the end part of the needle, and the part of the infusion needle, which exceeds the needle sleeve, is formed into a positioning head.

Furthermore, the front end of the positioning head is provided with a water outlet hole, the side wall of the needle sleeve is provided with water outlets, and the number of the water outlets is at least two and symmetrically arranged on the needle sleeve.

Furthermore, the bottom surface of the positioning head is formed into a round blunt surface, and the bottom surface of the positioning head is subjected to rough treatment.

Furthermore, the outer wall of the infusion handle is formed with anti-skid lines.

The beneficial effects of the utility model reside in that:

the anterior chamber maintaining and positioning device for ICL implantation operation provided by the application adopts a perfusion fluid infusion mode to maintain the filling of the anterior chamber, thereby avoiding using viscoelastic agent, reducing stimulation to patients and effectively preventing postoperative complications such as acute ocular hypertension and the like; the water outlet hole at the front end of the positioning head can ensure that the anterior chamber is formed quickly in the process of inserting the instrument into the incision, and avoid that the anterior chamber is excessively shallow caused by the overflow of water in the anterior chamber when the incision is spread but the water outlet hole does not enter the anterior chamber in the process of inserting the instrument; meanwhile, when the anterior chamber is maintained, the infusion needle can be directly used for adjusting the position of the implanted artificial lens.

Drawings

Figure 1 is a schematic structural diagram of the present invention,

fig. 2 is an enlarged schematic view of the structure of the infusion needle of the present invention.

Figure number and name: 1. the infusion device comprises an infusion needle head 11, a positioning head 2, a needle sleeve 21, a water outlet 3, an infusion handle 4, a catheter 5 and an infusion bottle.

Detailed Description

In order to explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following embodiments are described in detail with reference to the accompanying drawings.

With reference to fig. 1 and 2, the utility model discloses an anterior chamber maintaining and positioning device for an ICL implantation operation, which comprises an anterior chamber maintaining and positioning device for an ICL implantation operation, and comprises an infusion needle 1, wherein the infusion needle 1 is connected with an infusion handle 3, and a cavity communicated with the infusion needle 1 is formed inside the infusion handle 3; the tail end of the infusion handle 3 is provided with a water inlet hole communicated with the inner cavity, and the water inlet hole is connected with an infusion bottle 5 through a conduit 4; the infusion bottle 5 is internally provided with perfusion fluid, and the height of the infusion bottle 5 is greater than the working height of the infusion needle 1 when in use; the infusion needle 1 is sleeved with a needle sleeve 2.

The length of the needle sleeve 2 is smaller than that of the infusion needle 1, the needle sleeve 2 forms a closed-end shape at the end part close to the infusion needle 1, and the part of the infusion needle 1, which exceeds the needle sleeve 2, is formed into a positioning head 11.

Because the outer diameter of the sleeve is matched with the size of the incision, the incision is ensured to be closed after the sleeve is inserted into the incision, and the anterior chamber depth is maintained by means of water pressure of the water filling port.

The front end of the positioning head 11 is provided with a water outlet hole, so that the anterior chamber is ensured to be formed quickly in the process of inserting the instrument into the incision, and the excessive shallowness of the anterior chamber caused by the overflow of the water in the anterior chamber when the incision is spread but the water outlet hole does not enter the anterior chamber is avoided in the process of inserting the instrument; the side wall of the needle sleeve 2 is provided with at least two water outlets 21, and the water outlets 21 are symmetrically arranged on the needle sleeve 2, so that the uniform and mild water outlet of the infusion needle is ensured, and the stimulation to a patient is prevented.

The bottom surface shaping of transposition head 11 is round blunt face, and the bottom surface of transposition head 11 is through rough processing, and the frictional force when increasing transposition head bottom surface and intraocular lens contact makes things convenient for the doctor to utilize the infusion syringe needle can directly carry out the transposition to the crystal.

The outer wall of the infusion handle 3 is formed with anti-slip lines, so that a doctor can hold the infusion handle conveniently and can prevent slipping.

In summary, the preferred embodiments of the present invention are only examples, and the scope of the present invention is not limited thereto, and all equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the specification are within the scope covered by the present invention.
