Description

Multifunctional eye pull hook manufacturing panel

Technical Field

The invention relates to the technical field of medical instruments, in particular to a multifunctional eye pull hook manufacturing panel.

Background

The ophthalmology operators need to have the pupils scattered when performing operations such as cataract extraction, intraocular lens implantation, vitreoretinal and the like so as to obtain good operation visual field and effect, but because the pupils cannot be scattered due to diseases such as iridocyclitis, glaucoma surgery, eye trauma and the like in some cases, great difficulty is brought to operation, and even serious postoperative complications are generated. For such cases, methods such as multi-site shearing of sphincter at pupillary edge, segmental shearing of lower iris cluster, segmental shearing of upper iris and the like are commonly adopted in the past to enlarge the area of the pupillary region and fully expose the anterior lens capsule, but bleeding and inflammatory reaction are easily caused, and the iris draw hook is increasingly widely applied to patients with rubeosis of iris, chronic uveitis, diabetes and long-term systemic anticoagulation treatment, due to the advantages of sufficient pupil expansion, small damage to iris, difficulty in causing inflammation and bleeding, furthest keeping the shape and function of pupil, improving postoperative vision and the like.

The early iris pull hook is also called as an iris lasso, is relatively simple to manufacture, mainly adopts materials such as steel wires and steel materials, has relatively large volume, and is widely applied to the intracapsular operation of large incision. With the development of microsurgery, the micro iris draw hooks are produced, and the iris draw hooks applied in the modern cataract surgery can be divided into two types, namely elastic iris draw hooks and hard iris draw hooks. The early elastic iris pull hook is made of nylon and silica gel, the pulling hook part is made of nylon, the top end is in a semi-ring shape, and the hook body part is provided with a slidable silica gel piece for controlling the length of the pulling part. The traction hook part is extended into the anterior chamber through a limbus puncture incision, and the size of the traction pupil is adjusted through a silica gel slide sheet. The design is used to the present day, and becomes the iris pull hook which is most widely applied at present. The hard iris pull hook is made of titanium, the top end of the hard iris pull hook is similar to that of the elastic iris hook, the tail end of the hard iris pull hook is provided with a small square baffle, and the action principle of the hard iris pull hook is similar to that of the elastic iris pull hook.

PMMA material is applied to the manufacture of the iris hook at the earliest time; nitinol is also used to make iris hooks, which has the advantage of being reusable and flexible. However, the iris draw hooks are mostly produced by import or large companies, are expensive and have single use, and domestic scholars design some simple iris draw hooks which are similar to elastic iris draw hooks in design and made of silver needles for acupuncture, nylon sutures and the like.

The method for self-making the iris hook by using the nylon suture comprises the following steps: adopting 4-0 polypropylene nylon suture, manually folding into an arc shape, instantly heating the two ends of the arc shape through temperature control, bending into a hook shape, and hooking the head part at the edge of a pupil: the hook body is sleeved with a silica gel sliding damping plug to control the interpupillary diameter. Although the self-made iris hook pulling method is simple and convenient and has low price, the yield of qualified products is low, and the method mainly has three problems: 1. the manual bending suture shape is not fixed; 2. the distance between the electrothermal coagulation head and the suture is difficult to control accurately, the suture is easy to burn when the electrothermal coagulation head is too close, the shaping effect is poor when the electrothermal coagulation head is too far, and the operation effect is influenced when the electrothermal coagulation head is deformed in the operation; 3. the trimming of the length of the pull hook head and the body part is complicated and not beautiful. The sizes of a batch of hooks which are manually bent and manufactured are uneven, so that the operation of an operator is directly influenced, the operation difficulty is easily increased, the operation time is prolonged, and the postoperative recovery effect of a patient is influenced.

If a doctor or a technician can use a certain pulling hook to manufacture the panel, the shape of the suture is fixed before electrocoagulation, the distance between the electrothermal coagulation head and the suture is controlled, the accurate cutting of the length of the pulling hook is realized, and the yield and the qualification rate of the self-made simple pulling hook can be greatly improved. In addition, if the fixing angle and length of the thread before electrocoagulation can be changed, the diversity of the self-made pulling hook can be realized, such as the bag pulling hook, the artificial lens fixing pulling hook and the like, so that the time, the economy and the labor cost are really saved, meanwhile, the diversity and the quality of the self-made product are improved, and the medical personnel and the patient can benefit together.

The search for the existing device did not find a device that has similar functions as those of the device.

Therefore, in summary, there is a need for a multifunctional eye-use pull hook making panel that can solve the problems of the traditional artificial iris pull hook making process and can precisely control the pull hook angle, the thermosetting distance, and the lengths of the head and the body of the pull hook, and no report is found about the novel eye-use pull hook making panel.
