Description

TECHNICAL FIELD

[0001] The utility model relates to medical supplies technical field, specifically point to a kind of conjunctival lymphatic vessel dilatation treatment with casing pipe side hanging needle. BACKGROUND

[0002] Conjunctival lymphatic vessel dilatation is a common ophthalmic disease, and the traditional treatment method has many defects.

[0003] In the past treatment means, more complex surgical instruments and methods are used. For example, some traditional surgical methods are difficult to accurately position the dilated lymphatic vessels and cysts, which can easily leave residual diseased tissue during the resection process. This not only increases the risk of disease recurrence, but also can cause subsequent complications such as inflammation. Traditional surgery often requires a larger incision to facilitate surgical operation, which can cause significant trauma to the conjunctiva. The recovery time of the conjunctiva after surgery is long and scarring is likely to occur, which affects the appearance and function of the eye. Moreover, a larger incision can also cause more bleeding during surgery, increasing the risk of surgery.

[0004] In addition, traditional surgery usually requires general anesthesia or local anesthesia, which requires the participation of a professional anesthesia team, significantly increasing the cost of treatment, and also increasing the risk that patients may face due to anesthesia, such as anaphylaxis. Postoperative suture treatment further aggravates the damage to the conjunctiva, and the patient needs to go through the tedious process of removing stitches after surgery, increasing the patient's pain and inconvenience. The complex operation process of the traditional treatment method determines that it cannot be simply carried out in outpatient clinics. Patients often need to be hospitalized, which undoubtedly increases the patient's economic burden and time cost.

[0005] In summary, the traditional conjunctival lymphatic vessel dilatation treatment method has obvious shortcomings in treatment effect, surgical trauma, anesthesia requirement, treatment cost and postoperative recovery, and there is an urgent need for a new treatment tool to overcome these problems. Conjunctival lymphatic vessel dilatation treatment with casing pipe side hanging needle has emerged as the times require, which can effectively solve the defects of the above-mentioned traditional treatment method and has great application value and popularization potential in the field of conjunctival lymphatic vessel dilatation treatment.

[0015] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively below with reference to the relevant drawings.

[0016] The preferred embodiments of the utility model are shown in the drawings.However, the utility model can be realized 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 utility model more thorough and comprehensive.

[0017] Embodiments

[0018] In combination with the drawings Figure 1 A kind of conjunctival lymphatic vessel dilatation treatment with cannula side hanging needle, including disposable sterile injection needle 1, the disposable sterile injection needle is equipped with sterile side hanging needle 2 acting as pillow core inside.

[0019] As the preferred embodiment of the present embodiment, the disposable sterile injection needle is 20G disposable sterile injection needle with length 37mm, outer diameter 0.9mm, inner diameter 0.6mm.

[0020] As the preferred embodiment of the present embodiment, the sterile side hanging needle is 80mm long, with a diameter of 0.3mm.

[0021] The utility model discloses in the specific implementation, treatment method: the patient suffers from eye drops 0.5% times the nox surface anesthesia 2, the mandible is placed under the mandibular support of slit lamp, the top of forehead is placed the frontal support, takes 20G disposable sterile injection needle (long 37mm, outer diameter 0.9mm, inner diameter 6mm), with sterile side hanging needle (long 80mm diameter 0.3mm) is inserted into 20G disposable sterile injection needle and is used as needle core, to needle tip, instructs the patient to look at the opposite side of the subconjunctival lymphatic vessel expansion, fully exposes vesicle, under the hand of slit lamp, holds the self-made sleeve side hanging needle, is 1~2mm away from the ball conjunctiva of the lower or side of subconjunctival vesicle and avoids ball conjunctiva blood vessel and is stuck into the surface layer ball conjunctiva, enters the ball conjunctiva and does not reach lymphatic vessel expansion and cyst when stopping needle, with sterile self-made sleeve side hanging needle's side hanging needle (needle core) slowly explores the lower of lymphatic vessel expansion and cyst along the conjunctival incision, and the side hanging needle tip exceeds lymphatic vessel expansion and cyst, slowly pulls out needle core when the needle tip completely hangs the expanded lymphatic vessel and cyst, and rotates needle core 180 ° along the direction of 20G puncture needle, and the needle core is extracted to the puncture needle tip, and slowly withdraws puncture needle and needle core, when the puncture needle tip retreats to the ball conjunctiva and expands the lymphatic vessel and vesicle and is taken out in the incision, and remains needle core, pulls out puncture needle, and uses 20G puncture needle tip to intercept the expanded lymphatic vessel and cyst. Occasionally, conjunctival local hemorrhage can be seen, and special treatment is not needed, and the local application of typical must be must eye drops, three times a day, gradually reduces the amount, and typical must be must eye cream is applied to the eye before sleep, and is used for one week.

[0022] Subconjunctival lymphatic vessel expansion is caused by trauma, inflammation, operation and other reasons to cause lymphatic vessel obstruction, and is the subconjunctival cyst formed by local lymphatic vessel expansion because lymphatic fluid cannot return to the vein through the lymphatic vessel.

[0023] The subconjunctival tissue has two sets of lymphatic vessel networks, and the shallow layer is smaller, and the polygonal network is formed under the conjunctival epithelium, and the position is slightly deeper than the small blood vessel; the deep layer lymphatic vessel is larger, and is located in the subconjunctival fibrous layer. The single or multiple cystic lymphatic vessel expansion under the conjunctival epithelium or the conjunctival proper layer has obvious boundary with the underlying fascia. Therefore, the subconjunctival tissue is loose, the cyst is attached to the conjunctiva, and even can be free in the subconjunctival tissue, so that the self-made sleeve side hanging needle under the slit lamp can completely remove the expanded lymphatic vessel and cyst, without remaining, small incision, without suture needle, and surface anesthesia, which is low in cost, simple and easy to operate, and can be completed under the slit lamp in outpatient department, and the postoperative reaction is small, the conjunctiva is smooth and flat, no complications occur, and it is safe and reliable, easy to accept, and easy to promote in ophthalmic outpatient department.

[0024] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the description. The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of variations and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
