Description

Sclera exposure device for ophthalmologic operation

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a sclera exposure device for an ophthalmologic operation.

Background

Eye trauma is a common and frequently encountered disease in ophthalmology, and scleral laceration is common among them. Scleral lacerations require surgical closure of the scleral tear to reduce or avoid the associated complications. In the case of scleral laceration, the scleral tear is often covered by local tissues such as conjunctiva and fascia, which makes direct scleral suturing difficult. Therefore, it is critical to the success of the surgery to fully expose the scleral tear.

Currently, the scleral fissure surgery is performed by a primary surgeon and an assistant together. The assistant pulls the tissue covering the scleral tear open by the ophthalmic retractor to expose the scleral tear. The doctor holds the micro forceps and the micro needle holder and sews the scleral cleft at the exposed part. This type of surgery has the following drawbacks: the quality of the suture (whether the sclera is tightly closed) for the main surgeon depends on the degree to which the assistant exposes the sclera. If the assistant exposes the sclera poorly, fails to fully reveal the scleral tear, or provides too little suture access space for the surgeon, it is not conducive to high quality sutures.

In summary, the inexperienced assistant will greatly affect the success rate of the surgery, which results in poor prognosis of the eye after surgery, even serious complications such as endophthalmitis, blindness, and eyeball atrophy, and seriously affects the quality of life of the patient.

An effective solution to the problems in the related art has not been proposed yet.
