Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and relates to an eye surgery auxiliary instrument for eye repair, in particular to an integrated tool for turning over and measuring the eyelid tarsal plate. Background Art

[0002] Eye repair surgery is an exploratory and repair procedure for failed eye plastic surgery. Over the past five years, the proportion of surgeries performed in eye plastic surgery clinics has increased year by year. During the preoperative examination, planning, and surgery, the surgeon needs to flip the tarsal cartilage of the upper eyelid, evaluate the surgical results, measure physiological data, and collect scientific research data. During the operation, if the levator palpebrae superioris muscle strength is corrected, the tarsal cartilage needs to be flipped and a secondary anesthetic solution injected into the fornix conjunctiva. Patients who undergo eye repair surgery have previously undergone one or more eye surgeries, and the tarsal cartilage of the eyelid has developed moderate to severe adhesions with the surrounding tissues. This tarsal flipping and measurement operation is difficult and time-consuming. Surgeons are in urgent need of a surgical instrument that can quickly flip the eyelid tarsus and quickly complete accurate measurements to help shorten the operation time and reduce patient discomfort.

[0003] Currently, there is no dedicated eyelid tarsal cartilage flipping instrument among ophthalmic surgical instruments. Instruments for measuring eyelids, such as Chinese Patent Publication No. CN215273821U "A measuring ruler for ophthalmic surgery", use a needle-nose pliers-like instrument. The opening of the needle-nose pliers must be adjusted by a knob, and the opening is aligned with the upper and lower edges of the tarsal cartilage, and then the scale on the handle of the pliers is read. During the actual surgical operation, the eyelid still needs to be flipped laboriously first, and then another person operates the measuring ruler to measure, resulting in a waste of manpower, inconvenience in operation, and a waste of time. Summary of the Invention

[0004] In response to the problems in the prior art that there is no dedicated tarsal cartilage flipping instrument and that the measuring instrument must be replaced to complete the measurement work, which causes inconvenience in surgical operation and is time-consuming and labor-intensive, the purpose of the instrument of the utility model is to provide an integrated tool that combines tarsal lifting, flipping and measuring tarsal width into one. The eyelid can be quickly flipped and then the tarsal width measurement can be quickly completed, so that the surgeon can complete the flipping and measurement steps with one hand, which is convenient, fast, and saves time and effort.

[0005] In order to achieve the above objectives, the specific technical solutions adopted by this utility model are as follows:

[0006] An ophthalmic surgical auxiliary instrument for eye repair, characterized in that: the instrument is a flat, shovel-shaped long rod made of 304 stainless steel, including a head, a neck, and a handle. The head is divided into a rectangular hook back plane and a flat hook with a curved outer end of the hook back plane. The inner end of the hook back plane gradually becomes a neck of a thin round rod, and the neck gradually becomes a flat handle. The hook back plane of the head is engraved with a measuring scale for measuring the width of the tarsal plate. The handle is pulled with horizontal stripes or rolled with a grid pattern to prevent slipping. During operation, the middle part of the eyelid tarsal cartilage is first lifted up with the flat hook on the head and quickly turned over, and then the hook back plane is used to approach the middle of the tarsal plate for measurement and reading.

[0007] The angle (α) between the flat hook on the head and the hook back plane is 30° to 50°, preferably 40°; the length (D) of the flat hook is 4mm to 8mm, preferably 6mm; the width (W) of the hook back plane is 6mm to 10mm, preferably 8mm; the length (H) of the hook back plane is 10mm to 15mm, preferably 12mm.

[0008] The measuring scale on the plane is graduated in mm, and the scale lines at 6 mm, 7 mm, and 8 mm are elongated or scales are engraved on both sides as common scale marks.

[0009] The joints of the device are all smooth transitions, and the overall length (L) of the device is 100mm to 140mm, preferably 125mm.

[0010] The stainless steel material is 304 type stainless steel which is corrosion-resistant and heat-resistant.

[0011] The handle is engraved with measuring scales and is used as a ruler to assist in other measurements that may be required during surgery.

[0012] The positive and beneficial effects of the utility model are: integrating and simplifying the flipping of the upper eyelid and the measurement of the tarsal plate, having a simple and lightweight structure and convenient operation, helping doctors to simplify the process during the operation where every second counts, shorten the operation time, reduce personnel participation, reduce patient discomfort, and achieve a fast and accurate positive effect.
