A double drainage drainage device for ophthalmic surgery

Abstract

A double drainage drainage device for ophthalmic surgery comprises a negative pressure balloon (1), characterized in that two catheters (2) are connected to the top of the negative pressure balloon (1), two suction heads (3) are connected to the two catheters (2), the head of the suction head (3) is an elbow, and the elbow ends of the two suction heads (3) are adjacent, and the elbow ends are provided with a plurality of drainage holes (31). The accumulated fluid enters the suction tube through the drainage holes (31) of the two suction heads (3), and enters the negative pressure balloon (1) through the catheter (2), which can improve the drainage efficiency and effectively improve the accumulation of fluid in the conjunctival sac during surgery; while draining the fluid, as the accumulation of fluid in the balloon increases, the outer canthus angle can be made lower than other ocular surface tissues due to gravity, so that the accumulated fluid quickly flows out of the ocular surface, achieving the purpose of keeping the surgical field clear.

Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a double drainage drainer for ophthalmic surgery. Background Art

[0002] Currently, during ophthalmic microsurgery such as cataracts and vitrectomy, regular ocular surface flushing is required to keep the cornea moist and the field of vision clear. However, after flushing, patients with deep eye sockets and small palpebral fissures may experience water accumulation in the conjunctival sac, which seriously affects the surgical field of view and makes the operation difficult. Assistants or nurses are required to absorb the liquid with cotton swabs, gauze, etc. This operation is cumbersome and cannot effectively improve the water accumulation. Utility Model Content

[0003] In view of the problems and shortcomings in the prior art, the utility model provides a double drainage drain for ophthalmic surgery.

[0004] The technical solution of this utility model is as follows:

[0005] A double drainage drain for ophthalmic surgery includes a negative pressure balloon, characterized in that two catheters are connected to the top of the negative pressure balloon, two suction heads are connected to the two catheters, the heads of the suction heads are elbows, and the elbow ends of the two suction heads are adjacent, and multiple drainage holes are provided at the elbow ends.

[0006] In specific applications, the suction head is connected to the negative pressure balloon through a catheter, and the drain is hung on the lateral canthus of the surgical patient through the elbow of the suction head. When there is too much fluid accumulation in the conjunctival sac, the accumulated fluid enters the suction head through the drainage holes of the two suction heads through the action of the negative pressure balloon, and enters the negative pressure balloon through the catheter. At the same time, as the fluid accumulation in the balloon increases, the lateral canthus can be lower than other ocular surface tissues due to gravity, allowing the accumulated fluid to flow out of the ocular surface to achieve the purpose of keeping the surgical field clear.

[0007] In a specific implementation, the elbow is bent downward toward the side away from the negative pressure balloon, and the end is spherical. The elbow is used to hang on the outer canthus of the surgical patient, and the end adopts a spherical structure, which can minimize the damage to the patient's eye tissue.

[0008] In one embodiment, the two suction heads are symmetrically arranged, which is beneficial to balancing the force on the patient's eyes and allows the drainage device to be stably hung on the patient's outer canthus.

[0009] In one embodiment, the suction head is a double-tube structure, including an inner tube and an outer tube sleeved outside the inner tube and connected thereto, and a plurality of drainage holes are provided at the end of the outer tube. The double-tube structure of the suction head is conducive to reducing the blockage of the suction head caused by the blockage of the drainage holes.

[0010] In one embodiment, the material of the suction head is stainless steel. In order to ensure the structural function of the elbow, the suction head needs to be made of hard material, and stainless steel has corrosion resistance and good processing performance, so the suction head is preferably made of stainless steel.

[0011] The negative pressure balloon is ellipsoidal, made of transparent scraping glue, and has scale lines on the outer surface. The height of the negative pressure balloon is 10-20cm, and the outer diameter in the middle is 3-6cm. In order to facilitate palm grip, the negative pressure balloon is designed to be ellipsoidal. At the same time, in order to adapt to the width of the human palm and provide good grip, the height of the negative pressure balloon should be 10-20cm, and the outer diameter in the middle should be 3-6cm. The airbag is made of transparent silicone that is elastic and can be restored to its original shape. There are scale lines on the outer surface to facilitate observation of the amount of internal fluid accumulation.

[0012] In a specific embodiment, the negative pressure balloon is a split structure, including a sphere and an upper cover, the upper cover is provided with two drainage ports and a vent, the drainage ports are connected to the catheter, the vent is provided with an air hole cover, and the bottom of the sphere is provided with an excretion port. The air hole cover is a silicone plug. The split design facilitates the cleaning of the inside of the negative pressure balloon, the drainage port is used to communicate with the catheter, the vent is connected to the outside air when it is opened, and forms a negative pressure when it is closed.

[0013] The catheter and the negative pressure balloon or the suction head are detachably connected by plugging. The detachable connection method is convenient for storage and disinfection after use.

[0014] The beneficial effects of the utility model are:

[0015] 1) Double suction head design. When there is too much fluid accumulation in the conjunctival sac, the accumulated fluid enters the suction head through the drainage holes of the two suction heads through the negative pressure balloon, and then enters the negative pressure balloon through the catheter, which can improve the drainage efficiency and effectively improve the situation of fluid accumulation in the conjunctival sac during surgery.

[0016] 2) The accumulated fluid enters the negative pressure balloon through the catheter. As the fluid is drained, as the accumulated fluid in the balloon increases, gravity can cause the lateral canthus to be lower than other ocular surface tissues, allowing the accumulated fluid to quickly flow out of the ocular surface, thereby achieving the purpose of maintaining a clear surgical field of view.
