Description

Auxiliary tool and method for knotting suspension wire in artificial lens suspension operation Technical Field The invention relates to the technical field of hanging wire knotting, in particular to a hanging wire knotting auxiliary tool and a method in an artificial lens hanging operation. Background After the intraocular lens is implanted in the eyes of the patients, the intraocular lens needs to be fixed in front of the crystalline lens, so that the intraocular lens is prevented from loosening in the normal life and movement process of the patients after operation. The existing mainstream surgery comprises the following treatment processes that an artificial lens is implanted into an eyeball by a special tool in the surgery, the artificial lens is automatically unfolded under the action of self material tension, the special tool is used for adjusting the position, two self-contained loop wires on the artificial lens face to a fixed position, a special 10-0 suture line for the surgery is used for implantation into the eyeball, two hands are matched for operation, while holding the loop wires of the artificial lens, the other hand uses forceps to wind a double-strand surgical suture line around the head protruding part of the loop wires of the artificial lens for two circles clockwise, then the suture line is opened and sleeved into the head protruding part of the loop wires of the artificial lens, and finally the suture line is pulled to complete knotting operation. The other end of the suture was then sutured to the lens capsule structure, and the capsule began to fibrillate and shrink 2-4 weeks after the patient's operation, forming a dense "farther sleeve", integrating the suture with the capsule, and the capsule with the ciliary body. In the step of knotting the suture thread and the artificial lens loop in the operation process or the operation simulation training, an operator is required to cooperatively operate with two hands under a microscope, a series of operations such as suture thread pulling, winding, stripping, lasso and the like are completed in a very small operation space, the operator is required to be strictly required, the operation time is long, the efficiency is low, and the experience of a patient on the operation is poor. Currently, no tool equipment is available on the market for assisting an operator in completing the knotting operation or the knotting simulation training operation. Therefore, how to provide a suspension wire knotting auxiliary tool and a method in an intraocular lens suspension operation, which can assist in completing knotting operation between a suture and an intraocular lens loop when an ophthalmologist performs the intraocular lens suspension operation, and can complete a complex operation process by simple operation without winding operation of the suture in eyes of a patient, thereby saving a great deal of operation time, and helping to reduce damage risk to tissues in eyes of the patient while ensuring operation quality is a problem which needs to be solved by those skilled in the art. Disclosure of Invention In view of the above, the present invention provides an auxiliary tool and method for knotting a suspension string in an intraocular lens suspension operation, which aims to solve at least one of the above-mentioned problems. In order to achieve the above purpose, the present invention adopts the following technical scheme: The invention provides a hanging wire knotting auxiliary tool in an intraocular lens hanging operation, which comprises a needle head assembly, wherein the needle head assembly comprises a needle head pipe and an auxiliary knotting pipe, one end of the needle head pipe is a penetrating end, an annular winding knotting groove is coaxially arranged at the position, close to the penetrating end, of the inner peripheral wall of the needle head pipe, an operation through hole is formed at the position, corresponding to the winding knotting groove, of the outer peripheral wall of the needle head pipe, one end of the auxiliary knotting pipe can be adapted to coaxially slide from the other end of the needle head pipe to penetrate and extend into the winding knotting groove to form a suture winding knotting shaping end, and an inner hole at one end of the auxiliary knotting pipe is an intraocular lens penetrating hole; The needle head tube is characterized in that a threading groove is formed in the inner peripheral wall of the needle head tube along the length direction of the needle head tube, two ends of the threading groove are opened, one end of the threading groove is communicated with the winding and knotting groove, and the other end of the threading groove extends to the other end of the needle head tube. When the auxiliary tool for hanging the wire knot in the artificial lens hanging operation is used, one end of the auxiliary knot tying tube coaxially penetrates into the needle head tube, the suture winding knot tying end of the
