Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field, concretely relates to a kind of lens posterior capsule membrane water polishing head with perfusion. BACKGROUND

[0002] Cataract refers to the protein denaturation in lens and the occurrence of turbidity due to various reasons such as aging, heredity, local nutritional disorder, immunity and metabolic abnormality, trauma, poisoning, radiation, etc. Part of cataract, especially the cataract with turbidity under posterior capsule, the turbid or calcified lens cortex and capsule membrane are closely adhered, and IA cannot easily suck out these turbid or calcified lens cortex, and sometimes even the IA head cannot remove these turbid through polishing.

[0003] In the prior art, some doctors polish through polisher or injection needle of viscoelastic agent, which increases the risk of posterior capsule membrane rupture; and many existing capsule polishers are mainly for anterior lens capsule, and cannot be applied to posterior capsule polishing. Some doctors use syringe and flushing needle to flush the posterior capsule with concentrated water flow to achieve polishing effect, which is called water polishing in the industry. However, the flushing method using only syringe and flushing needle has two disadvantages, the first one is that perfusion needs to be carried out at the same time when flushing needle enters anterior chamber, which causes the flushing of corneal posterior limiting layer of incision margin at the moment of entering anterior chamber, which can cause the separation of corneal posterior limiting layer and corneal endothelium, resulting in surgical complications; the second one is that after flushing needle enters anterior chamber, the diameter of flushing needle is generally less than 1mm, and the diameter difference between flushing needle and incision is large, which causes rapid water leakage of incision, and anterior chamber cannot be stabilized, so that the posterior lens capsule has the risk of being punctured by flushing needle.

[0020] First perfusion pipe 2 connects syringe, and the operator flexibly applies pressure to the piston handle of syringe, and intraocular perfusion fluid in syringe is flushed out from first liquid outlet hole 4 at the most front end of water polishing head body 1 after first perfusion pipe 2, forms concentrated water flow to flush the posterior capsule, and achieves the effect of removing turbid or calcified lens cortex;Second perfusion pipe 3 connects infusion apparatus, and intraocular perfusion fluid in infusion apparatus flows out from two second liquid outlet holes 5 at the left and right sides of the front end of water polishing head body 1 after second perfusion pipe 3, and plays the role of maintaining the anterior chamber. Using the water polishing head of the embodiment, the cortex residue of the posterior lens capsule can be removed through the liquid flow flushing effect without affecting the corneal posterior limiting layer and ensuring the safety of the posterior lens capsule, so that the postoperative vision of the patient is improved. The water polishing head is simple in structure, convenient to operate, more safe and effective compared with other posterior capsule polishing methods at present, and very easy to master for novice doctors of cataract surgery.

[0021] The water polishing head of the embodiment is used in cooperation with a syringe (without needle) and an infusion device (without needle). Both the syringe and the infusion device are existing. Exemplarily, the syringe comprises a barrel, a nipple, a piston, a piston shaft and a piston handle. Exemplarily, the infusion device comprises an infusion tube, a puncture device, an air filter, a liquid filter, a drip bottle and a flow rate regulator, etc. The intraocular perfusion liquid inflow rate in the infusion device can be controlled by the infusion bottle hanging height and the flow rate regulator.

[0022] In the embodiment, the rear end of the first perfusion tube 2 is connected with a silica gel hose 6, and the rear end of the silica gel hose 6 is provided with a needle plug which is used in cooperation with the nipple to more conveniently connect the syringe and the first perfusion tube 2 together.

The intraocular perfusion liquid is discharged in a “flowing” manner at the second liquid outlet hole 5, and the second liquid outlet hole 5 does not need to be directly connected with the second perfusion tube 3, so that the cavity 7 is used to connect the second perfusion tube 3 and the second liquid outlet hole 5. Generally, the water polishing head body 1, the first perfusion tube 2, the second perfusion tube 3 and the connecting tube 8 are integrally formed to reduce the processing cost.
