Description

Technical Field

[0001] This invention relates to a bipolar electrocoagulation forceps for pupillary iris suturing, belonging to the field of electrocoagulation forceps technology. Background Technology

[0002] Pupilloplasty is an ophthalmic surgery used to correct abnormal pupil morphology, primarily treating complications such as upward pupillary displacement and deformation after cataract surgery. This procedure improves vision by adjusting the iris structure and provides conditions for the diagnosis and treatment of fundus diseases; it is often performed in conjunction with cataract extraction and intraocular lens implantation. During pupilloplasty, the surgeon needs to suture the incised iris to reduce the size of the enlarged pupil. In a routine pupilloplasty procedure, the surgeon makes a small incision at the limbus and uses a microscope or magnifying glass to separate the pupillary sphincter muscle from surrounding tissues to enlarge the pupil by incising the iris. The incised iris is then sutured using a single-needle double-suture technique. Currently, iris suturing often employs techniques such as single-needle double-suture, which, due to the narrow space of the iris, is technically challenging, time-consuming, and increases the patient's prognosis time.

[0003] Electrocoagulation forceps (referred to as "electrocoagulation suturing forceps") are a type of professional medical device that integrates the dual functions of "electrocoagulation hemostasis" and "suturing assistance". The core of it uses high-frequency current to precisely coagulate tissue and blood vessels, while assisting in completing key steps in the suturing operation such as tissue fixation and blood vessel closure. It is widely used in delicate surgeries such as ophthalmology, neurosurgery, and plastic surgery, which have extremely high requirements for the synchronization of "hemostasis-suturing". It is a core tool for reducing intraoperative bleeding and improving suturing accuracy.

[0004] Traditional electrocoagulation forceps (including those used in ophthalmology) have large electrocoagulation heads and are entirely conductive, which can affect surrounding tissues during iris suturing, making them unsuitable for iris suturing. Summary of the Invention

[0005] The purpose of this invention is to provide a bipolar electrocoagulation forceps for pupillary iris suturing, which combines electrocoagulation forceps with capsulorhexis forceps. The tip of the extremely fine capsulorhexis forceps is connected and conductive to a toothed component. The entire toothed component is wrapped with an insulating layer, and only one side of the "tooth" is exposed, thereby improving the accuracy of the electrocoagulation forceps and avoiding damage to surrounding tissues.

[0006] The present invention adopts the following technical solution:

[0007] A bipolar electrocoagulation forceps for pupillary iris suturing includes a toothed electrocoagulation platform 1, a capsulorhexis forceps arm 2, and a bipolar electrocoagulation metal rod 3. The toothed electrocoagulation platform 1 includes conductive teeth 102 and an insulating wrapping block 101, which wraps around the conductive teeth 102, exposing only the tips of the conductive teeth 102 on one side in the gripping contact direction. The capsulorhexis forceps arm 2 has a conductive inner core and an insulating outer layer. The distal end of the conductive inner core is connected to and conducts through the conductive teeth 102, and the proximal end is connected to the bipolar electrocoagulation metal rod 3. The capsulorhexis forceps arm 2 has a thin rod structure with an outer diameter smaller than that of the insulating wrapping block 101. The bipolar electrocoagulation metal rod 3 has a thick rod structure with an outer diameter larger than that of the insulating wrapping block 101, and includes a thick insulating layer 4 on the outside.

[0008] Preferably, the thickness of the thick insulating layer structure 4 is ≥5mm and the length is 150mm.

[0009] Furthermore, the length of the thin rod structure is 40 mm.

[0010] Furthermore, the insulating layer of the insulating wrapping block 101 is 1mm thick and rectangular in shape.

[0011] Furthermore, the length of the insulating wrapping block 101 is 15-20mm.

[0012] Furthermore, the thick insulating layer structure 4 surrounding the pair of thick rod structures is connected by a spring.

[0013] Preferably, the proximal end of the conductive inner core is connected to the rear conductor 5, and the rear conductor 5 is connected to the electrocoagulation machine.

[0014] Preferably, the tooth height of the tooth tip portion of the single-sided exposed conductive tooth 102 is 0.5-1mm.

[0015] Furthermore, the thick insulating layer structure 4 is the handheld part, which is provided with anti-slip texture.

[0016] The beneficial effects of this invention are as follows:

[0017] 1) Combine electrocoagulation forceps with capsulorhexis forceps, connect and conduct the head of the capsulorhexis forceps to a toothed component, wrap the entire toothed component with an insulating layer, and expose only one side of the "tooth" part, thereby improving the accuracy of electrocoagulation forceps and avoiding damage to surrounding tissues.

[0018] 2) The distal end of the capsulorhexis forceps is designed with an insulated thin rod structure, and the proximal end is designed with an insulated thick rod structure. Proportionally, the diameter of the thick rod structure is much larger than that of the thin rod structure, which ensures the stability of holding the hand and is also more conducive to operation in the narrow space of iris suturing.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] The terms “proximal,” “distal,” and “head” used in this article are based on the relative orientation and position of the various parts and components of a medical device. Although not restrictive, “proximal” usually refers to the end of the medical device that is closer to the surgeon during normal use, while “distal” and “head” usually refer to the end of the medical device that is farther away from the surgeon.

[0025] Some electrocoagulators used in ophthalmic electrocoagulation also lack a specific design for iris electrocoagulation. Their electrocoagulation points are often located at the very tip of the electrocoagulator, which is very sharp and makes it difficult to stably control the iris, which is moistened by aqueous humor on both sides, in actual operation.

[0026] Specifically:

[0027] Limited operating space: The anterior chamber volume is small (the depth of the anterior chamber in adults is usually only 2.5-3mm), and traditional hand-held suturing instruments (such as straight needles and curved needles) have limited range of movement in it, making it difficult to accurately control the needle insertion angle and depth.

[0028] Suturing precision is difficult to control: The iris tissue is thin (about 0.1-0.2mm) and fragile. Traditional surgical methods require manual adjustment of suture tension, which can easily lead to "too loose sutures causing pupil rebound" or "too tight sutures causing iris ischemia". It requires a high level of experience and feel from the surgeon, and novice doctors find it difficult to master quickly.

[0029] This embodiment provides a bipolar electrocoagulation forceps with a toothed electrocoagulation platform for pupillary shaping. It combines an electrocoagulation device with capsulotomy forceps and a toothed electrocoagulation platform at the forceps tip. Only the teeth of this toothed electrocoagulation platform have electrocoagulation functionality; the remaining surface is covered with a high-friction coefficient insulating material. This allows the surgeon to directly use the toothed electrocoagulation platform attached to the forceps tip to clamp the iris that has been cut on both sides during pupillary shaping and perform electrocoagulation, thereby completing the iris suturing. The entire process is simple and quick, with low operational difficulty and short operation time, improving surgical safety and success rate, and enhancing postoperative outcomes.

[0030] Detailed Explanation: In pupillary reconstruction surgery, suturing the incised irises on both sides is crucial to the success and safety of the procedure. Traditional pupillary reconstruction often employs single-needle double-suture techniques, which can hinder the surgeon's operation, increase surgical difficulty, and introduce more risks. In conventional pupillary reconstruction, the surgeon makes a small incision at the limbus and uses a microscope or magnifying glass to separate the pupillary sphincter muscle from surrounding tissues to enlarge the pupil and incise the iris. Then, a single-needle double-suture technique is used to suture the incised iris. This invention combines electrocoagulation, capsulorhexis forceps, and a toothed electrocoagulation platform with forceps tips. During iris suturing, it eliminates the need for traditional single-needle double-suture techniques, preserving the surgeon's operating habits. The toothed electrocoagulation platform can be used to stably clamp both irises before electrocoagulation and suturing, reducing surgical difficulty, shortening operation time, lowering the risk of complications, and increasing surgical safety.

[0031] See Figure 1-3 The device comprises the following components: a toothed electrocoagulation platform 1, a capsule tearing forceps arm 2, a bipolar electrocoagulation metal rod 3, a thick insulating layer 4, a rear conductor 5, and an electrocoagulation machine 6 connected to the rear conductor.

[0032] See Figure 2-3 A bipolar electrocoagulation forceps for pupillary iris suturing includes a toothed electrocoagulation platform 1, a capsulorhexis forceps arm 2, and a bipolar electrocoagulation metal rod 3.

[0033] See Figure 2 The toothed electrocoagulation platform 1 includes conductive teeth 102 and insulating wrapping block 101. The insulating wrapping block 101 wraps the conductive teeth 102, with only the tip of the conductive teeth 102 exposed on one side in the clamping contact direction.

[0034] Meanwhile, the capsule tearing forceps arm 2 has a conductive inner core and an insulating outer layer (not shown in the attached diagram); the distal end of the conductive inner core is connected to and conducts through the conductive teeth 102, and the proximal end is connected to the bipolar electrocoagulation metal rod 3; the capsule tearing forceps arm 2 has a thin rod structure with an outer diameter smaller than the insulating wrapping block 101; the bipolar electrocoagulation metal rod 3 has a thick rod structure with an outer diameter larger than the insulating wrapping block 101, and includes a thick insulating layer 4 on the outside, such as... Figure 2-3 As shown.

[0035] In this embodiment, the thickness of the thick insulating layer structure 4 is ≥5mm and the length is 150mm.

[0036] In this embodiment, the length of the thin rod structure is 40mm, such as... Figure 2-3 As shown.

[0037] In this embodiment, see Figure 1 The insulating layer of the insulating wrapping block 101 is 1mm thick and rectangular in shape.

[0038] In this embodiment, the length of the insulating wrapping block 101 is 15-20mm.

[0039] In this embodiment, the thick insulating layer structures 4 surrounding the pair of thick rod structures are connected by a spring, such as... Figure 2 As shown.

[0040] In this embodiment, see Figure 1 The proximal end of the conductive inner core is connected to the rear conductor 5, and the rear conductor 5 is connected to the electrocoagulation machine 6.

[0041] In this embodiment, see Figure 2 The tooth height of the tooth tip portion of the single-sided exposed conductive tooth 102 is 0.5-1mm.

[0042] In this embodiment, see Figure 2-3 The thick insulating layer structure 4 is the hand-held part, and it is provided with anti-slip texture.

[0043] This invention relates to a bipolar iris electrocoagulation forceps with a toothed electrocoagulation platform designed for pupillary shaping, with a rear lead wire connected to the electrocoagulation machine. This device allows for direct clamping of both irises using the toothed electrocoagulation platform during pupillary shaping surgery, followed by electrocoagulation suturing, reducing surgical difficulty, shortening operation time, lowering the risk of complications, and increasing surgical safety and treatment effectiveness.

[0044] Some existing electrocoagulators used in ophthalmic electrocoagulation lack specific designs for iris electrocoagulation. Their electrocoagulation sites are often located at the very fine tip of the device, making it difficult to stably control the slippery iris covered in aqueous humor during actual operation. This increases the difficulty of the procedure and the risk of damaging other healthy irises during electrocoagulation. These issues negatively impact pupillary shaping surgery. The product in this application effectively solves these problems by designing a bipolar iris electrocoagulation forceps with a toothed electrocoagulation platform for pupillary shaping. By combining the electrocoagulation device with capsulorhexis forceps, the surgeon can directly use the toothed platform of the electrocoagulation forceps to grasp the incised iris on both sides during pupillary shaping and perform electrocoagulation, thereby completing the iris suturing. The entire process is simple and quick, with low operational difficulty and short operation time, improving surgical safety and success rate, and enhancing postoperative outcomes.

[0045] In pupillaryoplasty, the surgeon uses the toothed electrocoagulation platform of forceps to grasp the iris that has been cut on both sides, and then electrocoagulates the iris directly through the platform to complete the suture. The whole process is simple, quick, and has low difficulty and short operation time.

[0046] The electrocoagulation platform in this invention is a toothed electrocoagulation platform, which is a tiny square electrocoagulation platform with a thickness of 1mm and a size of 2*2mm. The surface has teeth to facilitate gripping and holding the iris. Only the toothed surface of the electrocoagulation platform has electrocoagulation function, while the rest of the platform surface is an insulated platform. While providing sufficient gripping force to stably clamp the iris on both sides, it also minimizes damage to the other normal iris during electrocoagulation.

[0047] The rear wire connects to the electrocoagulation machine, which is equipped with an electrocoagulation time protection device. If the electrocoagulation time exceeds three seconds each time, the connection between the wire and the rear electrocoagulation machine will be automatically disconnected to prevent irreversible damage to the iris due to excessive electrocoagulation time.

[0048] The use of the capsulorhexis forceps arm of the electrocoagulation forceps is the same as that of the traditional capsulorhexis forceps, which does not affect the surgeon's operating habits and requires no additional learning period; it also does not require additional corneal incisions and does not increase intraoperative trauma.

[0049] In summary, this invention combines electrocoagulation forceps with capsulorhexis forceps. A toothed component connects to the head of the capsulorhexis forceps and provides electrical conductivity. An insulating layer covers the entire toothed component, with only one side of the "tooth" exposed. This improves the precision of the electrocoagulation forceps and avoids impacting surrounding tissues. The distal end of the capsulorhexis forceps is designed as an insulated thin rod structure, while the proximal end is designed as an insulated thick rod structure. Proportionally, the diameter of the thick rod structure is much larger than that of the thin rod structure, ensuring stability when held and facilitating operation within the confined space of iris suturing.

[0050] The above are preferred embodiments of the present invention. Those skilled in the art can make various modifications or improvements based on these embodiments. Without departing from the overall concept of the present invention, such modifications or improvements should fall within the scope of protection claimed by the present invention.
