Description
Technical Field
The invention relates to the technical field of vitreous cavity surgery operation instruments, in particular to an optical fiber flute needle.
Background
The vitreous body minimally invasive surgery is a main surgical method for treating posterior segment diseases of ophthalmology, and with the continuous improvement of vitreous body cutting surgical equipment and technology, more and more difficult cases receive the minimally invasive vitreous body cutting surgery, wherein the most popular vitreous body cutting surgery of 23G is developed.
Firstly, the yellow fissure foramen operation is one of the finest operations in the minimally invasive vitrectomy, the current operation mode with more definite curative effect in the yellow fissure foramen operation is the inner limiting membrane tearing and removing combined inner limiting membrane transplantation, but the transplanted inner limiting membrane graft is exposed to the risk of being sucked away by a cartesian needle during gas-liquid exchange, so that the operation fails.
Secondly, in the minimally invasive vitrectomy, many patients with complicated eye conditions have to select a vitreous cavity filled with silicone oil due to the condition, and the patients are exposed to the problem of taking out the silicone oil again after 3-6 months. For the vitreous cavity silicone oil extraction operation, a 3-channel sclera incision can be adopted as an operation incision, but a 2-channel sclera puncture incision is usually adopted clinically for reducing operation trauma, an infusion tube is usually placed by using Trocar puncture 3-4mm behind the corneal limbus below the temples, and an oil extraction tube is placed by using Trocar puncture 3-4mm behind the corneal limbus above the temples. The oil extraction method is characterized in that a 23G oil extraction needle head is connected to an oil extraction Trocar for vacuum oil extraction by a glass cutting machine, the method is slow in pumping speed, and the oil injection needle head is thin and short, so that oil droplets can easily escape from an oil extraction needle hole due to vortex generated by intraocular perfusate in the last stage of silicone oil extraction, and can not be easily removed due to rotation along with liquid flow in a glass cavity; the second method is to move out the Trocar sleeve, select a 20G indwelling soft needle head, trim the proper length as required, and adjust the direction of the oil taking pipe mouth according to the position of the oil bubble to avoid the oil bubble escaping when the oil taking is close to the tail sound. In any method, emulsified silicone oil droplets are remained in eyes after oil extraction, and a mode of partial gas-liquid exchange is generally used for replacing the silicone oil droplets remained in a vitreous cavity as much as possible clinically. Because 2 passageway sclera incisions get when oil, one is placed the filling tube and is used for the intraocular infusion, and another uses the flute needle to carry out partial gas-liquid exchange, because do not have lighting device, can't see the condition in the vitreous body intracavity clearly, leads to the gas-liquid exchange operation to have the blindness, moreover because can only partial gas-liquid exchange at every turn, leads to emulsified silica oil droplet to remain too much, influences the operation curative effect.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the optical fiber flute needle, the optical fiber illumination is arranged in the flute needle, after the inner limiting membrane of a patient suffering from macular hole operation is covered or plugged, complete gas-liquid exchange can be simultaneously carried out under good illumination by means of one operation incision, and the other incision can be used for assisting in fixing the inner limiting membrane implant to prevent the displacement of the inner limiting membrane implant by an intraocular instrument, so that the success rate of the inner limiting membrane implant is increased; and in the operation of taking out the silicone oil, complete gas-liquid exchange can be carried out simultaneously with good illumination by only one operation incision, so that emulsified oil drops are thoroughly replaced, the operation time is shortened, the operation wound is reduced, the inflammatory reaction after the operation of the affected eye is relieved, and the operation curative effect is improved.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
an optical fiber cartesian needle comprises a cartesian needle body, a needle head arranged at the front end of the cartesian needle body, an air bag arranged on the cartesian needle body, a hose, an illumination mechanism arranged in the hose and a light beam sleeve connected with the illumination mechanism; one end of the hose axially penetrates through the cartesian needle main body to be connected with the needle head, the other end of the hose is connected with the light beam sleeve, and the lighting mechanism extends to the end part of the needle head.
Further, the illumination mechanism is an optical fiber.
Compared with the prior art, the invention has the following beneficial effects:
the optical fiber illumination device is internally integrated into the cartesian needle, complete gas-liquid exchange can be simultaneously carried out on the inner limiting membrane covering or filling operation of a patient suffering from macular hole under good illumination by means of one operation incision, and the other incision can be used for assisting in fixing the inner limiting membrane implant to prevent the inner limiting membrane implant from shifting by an intraocular instrument, so that the success rate of transplanting the inner limiting membrane is increased; take out the operation at silicone oil then compare with 3 passageway incisions of traditional sclera and can reduce an operation incision, only need 2 operation incisions just can carry out thorough gas-liquid exchange replacement emulsion oil and drip: one incision is used for filling liquid, and the other surgical incision is used for completely exchanging gas and liquid while having good illumination so as to completely replace emulsified oil drops; because of good illumination, the controllability and the safety of the intraocular operation are improved, and the frequency required by partial gas-liquid exchange in the traditional sclera 2 channel incision mode is reduced, the operation time is greatly shortened, the operation wound is reduced, the inflammatory reaction after the operation of the affected eye is lightened, and the operation curative effect is improved.
