Description

Silicone Oil Clips for Ophthalmic Surgery

technical field

The utility model relates to a medical instrument, in particular to an ophthalmic surgical instrument, in particular to a silicone oil extraction clip for ophthalmic surgery.

Background technique

In 1958, Stone discovered that silicone oil, an inert transparent substance, could be used to treat retinal detachment in animal experiments. In 1962, Cibis first reported that silicone oil was injected into the vitreous cavity to treat complex retinal detachment. After the 1980s, vitrectomy surgery developed rapidly, and the concept of silicone oil as a temporary filling in the vitreous cavity has been accepted by people, and it is widely used in the treatment of complex vitreoretinal diseases, especially the increasing severity of ocular trauma, diabetic Retinopathy, etc. So far, medical intraocular silicone oil cannot be used as a long-term intraocular filler due to the inevitable emulsification changes in the eye, resulting in multiple ocular complications. The outcome of surgery has a huge impact. At present, the traditional intraocular silicone oil removal operation mostly adopts negative intraocular suction or discharge through the enlarged sclera puncture port, and relies on expensive vitreous surgery equipment. At the same time, problems such as residual silicone oil in the eye after surgery, shedding of the pigmented membrane in the scleral wound, intraocular hemorrhage, and high recurrent retinal detachment have also plagued ophthalmologists. With the rapid development of medical technology in my country, the number of patients with intraocular silicone oil filling after vitrectomy has increased sharply. Due to the imbalance of medical resources, these patients need to seek medical treatment many times remotely, which has become a huge medical burden. Therefore, there is an urgent need to design a safe, reliable, and easy-to-operate instrument, which can improve the operation method of intraocular silicone oil removal surgery, effectively avoid surgical complications, make intraocular silicone oil removal surgery easier and safer, and allow intraocular silicone oil to fill. Patients can undergo a relatively safe silicone oil removal operation in the nearest medical institution to avoid postoperative retinal detachment due to long-distance travel fatigue after the silicone oil removal operation.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

The utility model includes a grip part 3 made of sheet elastic material. The holding portion 3 is in the shape of a U-shaped clip, each of its ends is connected to a connecting portion 2 of the same length, and the other end of the connecting portion 2 is connected to a clamping portion 1 . The two clamping parts 1 have the same shape and size, are flat and thin rod-shaped, and are parallel to each other, and the distance between them is adapted to the length of the surgical incision. Each end of the clamping portion 1 is provided with a disc 4 facing each other. The diameter of the disc 4 is greater than the width of the joint with the clamping portion. In this way, when the gripping part 3 is squeezed inward, the connecting part 2 and the gripping part 1 can be driven inward until the two gripping parts 1 and the wafer 4 are completely attached; when the gripping part 3 is released, Under the action of elastic force, the clamping part 1 can be opened. Simultaneously, because the diameter of the disc 4 at the end of the clamping part 1 is greater than the width of the junction with the clamping part 1, so when the disc 4 is inserted into the slit, the disc 4 can be stuck in the slit to avoid easy detachment. According to the test, setting the difference between the diameter of the wafer 4 and the width of the joint with the clamping portion 1 at about 0.2 mm has the best effect. The two connecting parts 2 have the same shape, both are wedge-shaped, and their bottoms are on the same plane as the bottom of the holding part 3 , and the big end is connected to the holding part, and the small end is connected to the clamping part. The clamping part 1 is perpendicular to the bottom edge of the connecting part 2, and is connected with the hypotenuse of the connecting part 2 in a circular arc shape, which makes the utility model more convenient when used and can realize automatic rotation.

Embodiment 1, the gripping part 3, the connecting part 2, the clamping part 1 and the disc 4 of the utility model all use the same sheet-like elastic material, such as metal or plastic, and the above-mentioned parts are made into one piece. The clamping portion 1 has a uniform width of 0.6-0.8 mm, a height of about 8 mm, and a diameter of the end disc 4 of 0.8-1.2 mm. Preferably, the clamping portion 1 may have a width of 0.8 mm and a diameter of the disc of 1.0 mm. The two connecting parts 2 are parallel to each other, and the distance between them is the same as the distance between the clamping parts, which is 2.5-4mm, so that it is compatible with the length of the current general surgical incision of 2.0mm. The two sides of the holding part 3 protrude outward in an arc shape, and the maximum distance is 6-8 mm, so as to ensure moderate tension, which can fully open the holding part 1 without causing excessive tension. large resulting in enlargement of the incision. Further, for the convenience of operation, the total length of the utility model is set at about 2cm.

The usage method of the present utility model: after routine injection of 2% lidocaine injection 2.5ml after eyeball injection, surgical towel is spread on eye skin of disinfection operation, eyelid opener retracts eyelid, and 1.5-mm of sclera is lined outside 3.5mm of temporal inferior corneoscleral limbus. After the 2.0mm puncture, introduce the intraocular water injection tube; make a scleral puncture incision 1.5-2.0mm at 3.5mm outside the corneoscleral limbus above the nose or above the temporal, and press the holding part 3 of the silicone oil removal clip of the utility model to make the two holding parts 1 and 2. After the discs 4 at the ends are brought together, the discs 4 are fully inserted into the incision. Then, release the holding part 3 slowly, make it open under the action of elastic force, and drive the holding part 1 to open. Because the eyeball is spherical, and under the action of its internal pressure, the silicone oil removal clip of the utility model can be rotated 90° automatically or with the help of manpower, so that the disc 4 at the end of the clamping part 1 is just stuck on the two sides of the scleral puncture incision. Keep the incision open, so that the silicone oil can overflow smoothly from the scleral puncture incision. At the end of the operation, the clip is removed by slightly pressing the grip 3. Under the condition that all the basic steps of the operation remain unchanged, the utility model can also be used for taking out the silicon oil of the aphakic eye through the anterior chamber incision.

The parts not involved in the utility model are all the same as the prior art or can be realized by adopting the prior art.
