Description

Technical Field

[0001] This utility model relates to the field of cataract surgery technology, specifically a cataract capsulotomy guide ring structure. Background Technology

[0002] Cataract surgery is a delicate and efficient ophthalmic procedure designed to remove the cloudy lens of the eye and restore the patient's vision. During the surgery, doctors use advanced microsurgical techniques and equipment to access the eye through tiny incisions. In most cases, doctors use phacoemulsification, a technique that uses ultrasonic vibrations to break up and remove the hardened lens; this process is called phacoemulsification.

[0003] During cataract surgery, surgeons typically use the capsulorhexis ring technique to precisely insert the circumcision device into the appropriate position on the cornea. The device delivers 12 micropulses of energy in just 4 milliseconds. This rapid and precise energy release immediately creates a perfect 360-degree anterior capsular incision. Such an incision is crucial for optimizing lens positioning on the patient's visual axis. However, after the incision is made, the excised capsule remains beneath the cornea, hindering further surgery. To remove this residual capsule, surgeons must carefully extract it using specialized forceps. While necessary, this step undoubtedly reduces the efficiency of the procedure. Summary of the Invention

[0004] The purpose of this invention is to provide a cataract capsulotomy ring structure to solve the problem of secondary cleaning of the capsule in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cataract capsulorhexis guide ring structure, comprising a guide ring body, a connecting portion on the guide ring body, a positioning bracket fixedly installed on the connecting portion, a ring cutting assembly on the guide ring body, and an adsorption mechanism at the middle position of the guide ring body. The adsorption mechanism includes an adsorption head installed at the middle position of the guide ring body, an adsorption port at the bottom of the adsorption head, a silicone ring at the adsorption port, a positioning ring seat fixedly installed inside the adsorption head, an installation notch on the positioning ring seat, and a locking mechanism fixedly installed inside the installation notch.

[0006] Preferably, the adsorption head has a connection port on its side wall, and an adsorption pipe is connected to the connection port.

[0007] Preferably, a silicone ring slot is provided at the adsorption port, and the silicone ring is installed at the adsorption port through the silicone ring slot.

[0008] Preferably, the adsorption pipe is installed on the adsorption head via an interface, the locking mechanism is installed on the positioning ring seat via an installation notch, and the locking mechanism is installed at the adsorption port inside the adsorption head via the positioning ring seat.

[0009] Preferably, the locking mechanism includes a positioning sleeve fixedly installed in the installation notch, one end of the positioning sleeve has an air inlet, the other end of the positioning sleeve has a firing pin outlet, an air inlet is connected to an air inlet, a sealing membrane is provided in the firing pin outlet, a piston is movably installed in the positioning sleeve, and a locking firing pin is fixedly installed on the piston.

[0010] Preferably, the piston has a connection port, and the locking pin is mounted on the piston through the connection port.

[0011] Preferably, the positioning sleeve is installed on the positioning ring seat through the installation notch, the inflation pipe is connected to the positioning sleeve through the air inlet, the locking pin is installed inside the positioning sleeve by a piston, and the locking pin and the pin outlet are aligned front and back, the pin outlet on the positioning sleeve is blocked by a sealing membrane, and the locking pin extends out of the positioning sleeve through the pin outlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, after the membrane ring is removed, the gas inside the adsorption head can be drawn in through the adsorption pipe, thereby creating a negative pressure environment. Under negative pressure, the removed membrane portion will be guided into the adsorption head for subsequent processing.

[0014] 2. In this application, when the capsule enters the suction head, air is inflated into the positioning sleeve through the inflation tube, causing the locking pin to move forward. Subsequently, the locking pin extends through the pin outlet, penetrates the capsule inside the suction head, and fixes the capsule on the suction head. After the capsule is fixed, the guide ring body can be pulled out of the cornea, thereby quickly removing the circumcised capsule. This process helps reduce surgical steps and shorten surgical time.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a cataract capsulotomy guide ring structure, including a guide ring body 1, a connecting part 2 on the guide ring body 1, a positioning bracket 3 fixedly installed on the connecting part 2, a circumcision assembly 4 on the guide ring body 1, an adsorption mechanism 5 at the middle position of the guide ring body 1, and a locking mechanism 6 fixedly installed in the installation notch 507. Through the cooperation of the adsorption mechanism 5 and the locking mechanism 6, the circumcised capsule can be quickly removed, reducing surgical steps and shortening surgical time.

[0022] like Figure 2 and Figure 3 As shown, the adsorption mechanism 5 includes an adsorption head 503 installed in the middle of the guide ring body 1. The bottom of the adsorption head 503 has an adsorption port 505, and a silicone ring 506 is provided at the adsorption port 505. A positioning ring seat 504 is fixedly installed inside the adsorption head 503. An installation notch 507 is provided on the positioning ring seat 504. A mating interface 502 is provided on the side wall of the adsorption head 503. An adsorption pipe 501 is connected to the mating interface 502. A silicone ring groove is provided at the adsorption port 505. The silicone ring 506 is installed at the adsorption port 505 through the silicone ring groove.

[0023] Specifically, after the capsule resection surgery, a specific step can be taken to process the excised capsule tissue. Specifically, after the capsule is resected, the gas inside the adsorption head 503 can be extracted using the adsorption tube 501. This operation creates a negative pressure environment inside the adsorption head 503. Once a negative pressure is formed inside the adsorption head 503, a portion of the resected capsule will be attracted and enter the adsorption head 503 through the adsorption port 505. This facilitates subsequent processing of the resected capsule.

[0024] like Figure 2 and Figure 4 As shown, the locking mechanism 6 includes a positioning sleeve 603 fixedly installed in the mounting notch 507. One end of the positioning sleeve 603 has an air inlet 604, and the other end of the positioning sleeve 603 has a firing pin outlet 606. An air inlet 604 is connected to an air inlet pipe 601, and a sealing membrane 607 is provided in the firing pin outlet 606. A piston 602 is movably installed in the positioning sleeve 603. A locking firing pin 605 is fixedly installed on the piston 602. A connection port is provided on the piston 602, and the locking firing pin 605 is installed on the piston 602 through the connection port.

[0025] Specifically, after the capsule enters the suction head 503, air can be inflated into the positioning sleeve 603 through the inflation tube 601. Once the inner side of the positioning sleeve 603 is fully inflated, the locking pin 605 begins to move forward. During its forward movement, the locking pin 605 extends through the pin outlet 606 and passes through the capsule that has entered the suction head 503. In this way, the capsule is securely fixed to the suction head 503. Once the capsule is fixed to the suction head 503, the next step is to remove the guide ring body 1 from the cornea. Once the guide ring body 1 is removed from the cornea, the circumcised capsule can be quickly removed. This design and operating procedure effectively reduces surgical steps, thereby shortening the overall surgical time.

[0026] Working principle: During use, the guide ring body 1 is first accurately inserted into the appropriate position on the cornea. Then, a perfect 360-degree incision is made on the anterior capsule using the circumcision component 4. After the incision is completed, the suction head 503 is placed against the cut capsule. The gas inside the suction head 503 is then extracted using the suction channel 501, creating a negative pressure inside the suction head 503. Once a negative pressure is formed inside the suction head 503, a portion of the circumcised capsule will enter the suction head 503 through the suction port 505. After entering the suction head 503, the capsule can... Inflation is performed through the inflation tube 601 to the inside of the positioning sleeve 603. After inflation, the locking pin 605 moves forward and extends through the pin outlet 606. The extended locking pin 605 passes through the capsule inside the suction head 503, fixing the capsule to the suction head 503. After the capsule is fixed to the suction head 503, the guide ring body 1 can be pulled out of the cornea. The guide ring body 1 can be pulled out of the cornea to quickly remove the circumcised capsule, reducing surgical steps and shortening surgical time.
