Description

Technical Field

[0001] The invention relates to the technical field of medical supplies, in particular to a cannula side hanging needle for treating conjunctival lymphangiectasia. Background Art

[0002] Conjunctival lymphangiectasia is a common ophthalmic disease, and traditional treatment methods have many defects.

[0003] In previous treatment methods, more complex surgical instruments and methods were mostly used. For example, some traditional surgical methods make it difficult to accurately locate dilated lymphatic vessels and cysts, which can easily lead to residual diseased tissue during the resection process. This not only increases the risk of disease recurrence, but may also cause subsequent complications such as inflammation. Traditional surgeries often require larger incisions for surgical operations, which can cause greater trauma to the conjunctiva. The postoperative recovery time of the conjunctiva is long and scars are easily formed, affecting the appearance and function of the eye. Moreover, larger incisions may also lead to more bleeding during surgery, increasing surgical risks.

[0004] In addition, traditional surgery usually needs to be performed under general or local anesthesia, which requires the participation of a professional anesthesia team, which greatly increases the cost of treatment and also increases the risks that patients may face due to anesthesia, such as anesthesia allergy. Sutures are also required after surgery, which further aggravates the damage to the conjunctiva, and patients need to go through tedious processes such as suture removal after surgery, which increases the pain and inconvenience of patients. The complex operating procedures of traditional treatment methods determine that they cannot be simply carried out in outpatient clinics, and patients often need to be hospitalized, which undoubtedly increases the economic burden and time cost of patients.

[0005] In summary, the traditional treatment method of conjunctival lymphangiectasia has obvious shortcomings in terms of treatment effect, surgical trauma, anesthesia requirements, treatment costs and postoperative recovery. There is an urgent need for a new treatment tool to overcome these problems. The cannula side hanging needle for the treatment of conjunctival lymphangiectasia came into being, which can effectively solve the defects of the above-mentioned traditional treatment methods and has great application value and promotion potential in the field of conjunctival lymphangiectasia treatment. Summary of the invention

[0006] The purpose of the present invention is to solve the problems existing in the background technology and provide a cannula side hanging needle for treating conjunctival lymphangiectasia.

[0007] In order to solve the above technical problems, the technical solution provided by the present invention is: a cannula side hanging needle for treating conjunctival lymphangiectasia, comprising a disposable sterile injection needle, wherein the disposable sterile injection needle is sheathed with a sterile side hanging needle serving as a pillow core.

[0008] Preferably, the disposable sterile injection needle is a 20G disposable sterile injection needle with a length of 37 mm, an outer diameter of 0.9 mm, and an inner diameter of 0.6 mm.

[0009] Preferably, the sterile side hanging needle is 80 mm long and 0.3 mm in diameter.

[0010] The present invention has the following advantages: reasonable structural design, for the treatment of conjunctival lymphangiectasia, the dilated lymphatic vessels and cysts can be completely removed without residue, small incision, no need for stitches, surface anesthesia, low treatment cost, simple and easy, can be completed under the slit lamp in the outpatient clinic, minimal postoperative reaction, smooth and flat conjunctiva, no complications, safe and reliable, easy for patients to accept, and easy to promote in ophthalmology clinics.

[0015] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings.

[0016] The preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0017] Example

[0018] Combined with Figure 1 A cannula side hanging needle for treating conjunctival lymphangiectasia comprises a disposable sterile injection needle 1, wherein the disposable sterile injection needle is sheathed with a sterile side hanging needle 2 serving as a pillow core.

[0019] As a preferred implementation scheme of this embodiment, the disposable sterile injection needle is a 20G disposable sterile injection needle with a length of 37 mm, an outer diameter of 0.9 mm, and an inner diameter of 0.6 mm.

[0020] As a preferred implementation scheme of this embodiment, the sterile side hanging needle is 80 mm long and 0.3 mm in diameter.

[0021] When the present invention is implemented, the treatment method is as follows: the patient's affected eye is dripped with 0.5% Benoxetine topical anesthesia twice, the mandible is placed on a slit lamp mandibular support, the forehead is placed on a forehead support, a 20G disposable sterile injection needle (37mm long, 0.9mm outer diameter, 6mm inner diameter) is taken, and a sterile side hanging needle (80mm long, 0.3mm in diameter) is inserted into the 20G disposable sterile injection needle as a needle core to the needle tip, the patient is asked to stare at the opposite side of the dilated subconjunctival lymphatic vessels to fully expose the vesicles, and a self-made cannula side hanging needle is held under the slit lamp, and the surface is inserted 1 to 2mm below or to the side of the subconjunctival vesicle to avoid the bulbar conjunctival blood vessels. The needle is inserted into the bulbar conjunctiva. When the needle does not reach the lymphatic dilatation and cyst under the bulbar conjunctiva, the needle is stopped. The side hanging needle (needle core) of the sterile self-made cannula side hanging needle is slowly probed to the lymphatic dilatation and cyst below along the conjunctival incision. After the side hanging needle tip exceeds the lymphatic dilatation and cyst, the needle core is slowly withdrawn. When the needle tip completely hooks the dilated lymphatic vessels and cysts, the needle core is rotated 180° and the needle core is pulled out along the direction of the 20G puncture needle to the puncture needle tip, and the puncture needle and needle core are slowly withdrawn. When the puncture needle tip is withdrawn to the bulbar conjunctival dilatation lymphatic vessels and cysts out of the incision, the needle core is left in place, the puncture needle is pulled out, and the dilated lymphatic vessels and cysts are intercepted with the 20G puncture needle tip. Occasionally, local bleeding of the conjunctiva can be seen, and no special treatment is required. Topical application of Diabetes eye drops, three times a day, gradually reduce the amount, and apply Diabetes eye ointment to the eyes before going to bed for one week.

[0022] Conjunctival lymphangiectasia is caused by lymphatic obstruction due to trauma, inflammation, surgery, etc., which means that lymph fluid cannot flow back into the veins through the lymphatic vessels, and local lymphatic vessels dilate to form a subconjunctival cyst.

[0023] There are two sets of lymphatic vessels in the subconjunctival tissue, deep and shallow. The shallow ones are smaller, forming polygonal meshes under the conjunctival epithelium, and their position is slightly deeper than the small blood vessels; the deep lymphatic vessels are larger and located in the subconjunctival fibrous layer. The single or multiple cystic lymphatic vessels under the bulbar conjunctival epithelium or the conjunctival propria are dilated, and there is a clear boundary with the fascia below. Therefore, the subconjunctival tissue is loose, the cyst is less attached to the conjunctiva, and can even move freely under the conjunctiva. Therefore, the self-made cannula side hanging needle under the slit lamp can completely remove the dilated lymphatic vessels and cysts, without residue, small incision, no stitches, and surface anesthesia. This method is low-cost, simple and easy to perform, and can be completed under the outpatient slit lamp. The postoperative reaction is minimal, the conjunctiva is smooth and flat, and no complications occur. It is safe and reliable, easy for patients to accept, and easy to promote in ophthalmology clinics.

[0024] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above-described embodiments only express several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, several variations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
