TECHNICAL FIELD
[0001] The utility model relates to surgical knife technical field especially relates to a chalazion wedge resection surgical knife. BACKGROUND
[0002] The Meibomian gland is located in the inner eyelid and is an important gland that secretes lipid components in tear fluid. The normal function of the Meibomian gland is crucial for maintaining the stability of tear fluid and protecting the eye from dryness, irritation, and other external factors. However, with age, environmental factors, or the occurrence of certain ophthalmic diseases (such as Meibomian gland dysfunction, Meibomian gland inflammation, etc.), the Meibomian gland may become blocked or hyperplastic, leading to eye discomfort and even severe dry eye, conjunctivitis, and other ophthalmic diseases.
[0003] For the treatment of Meibomian gland disease, traditional methods usually include drug treatment, hot compress, massage, and other non-surgical interventions. However, for some patients with more severe conditions and ineffective drug treatment, surgical intervention may be necessary. In these surgical treatments, Meibomian gland wedge resection is one of the common surgical methods, which removes part of the Meibomian gland tissue to restore the normal function of the Meibomian gland and relieve symptoms. However, traditional Meibomian gland wedge resection surgery has certain technical difficulties and limitations, and there is an urgent need for a more precise and controllable surgical instrument.
[0004] Currently, the Meibomian gland wedge resection surgical knife has not been widely standardized in clinical application, and the existing surgical instruments are mainly based on traditional ophthalmic surgical knives, which cannot effectively meet the special needs of Meibomian gland wedge resection. Traditional surgical knives often lack precision when cutting the Meibomian gland, which can easily lead to excessive resection or incomplete resection, and even damage adjacent eye tissues, affecting the surgical effect and recovery. Although some improved surgical instruments have developed, they still have problems such as complex operation, unstable cutting, or easy to cause surgical trauma.
[0005] Chinese patent CN202776722U discloses a Meibomian gland cutting blade, characterized by: a V-shaped blade body, a V-shaped blade edge is formed at the front end of the V-shaped blade body, side edges for resting on the Meibomian gland are provided on the left and right sides of the V-shaped blade body, and the V-shaped blade body is connected to the handle through a connecting piece. After using the utility model, the two-knife surgery can be changed into one-knife surgery, saving the surgery time and improving the surgery quality.
[0006] The patent realizes that the surgery of two knives becomes one knife by the setting of the V-shaped knife body, saves the surgery time, but the depth of the resection is difficult to control, and on the basis of the difficult-to-control depth, the width is also difficult to control, therefore, a kind of eyelid plate wedge-shaped area resection scalpel is designed, which can accurately resect the eyelid plate wedge-shaped area, ensure that the damage to other tissues of the eyelid is reduced during the surgery process, improve the control of the cutting depth, and further improve the structure.

[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0026] EMBODIMENT
[0027] As Figs. 1-3 Indicated, a meibomian gland wedge shape resection scalpel, including handle 1, handle 2, the handle 1 is connected handle 2 through transition section 3;
[0028] The handle 1 includes V-shaped handle 11 and guard piece 12 fixed on the top of both sides of V-shaped handle 11, V-shaped blade 15 is equipped at the front end of V-shaped handle 11, depth scale 13 is equipped on V-shaped handle 11, length scale 14 is equipped on guard piece 12.
[0029] Depth scale 13 and length scale 14 on V-shaped handle 11 can help doctors more accurately control the resection depth and range, improve the accuracy and safety of operation.
[0030] It should be noted that the V-shaped blade body 11 is triangular at the end away from the blade 15, and is connected to the transition section 3 to form a closed shape, so that the removed meibomian glands do not leak out through the triangular groove and fall on the patient.
[0031] In this embodiment, the V-shaped blade body 11 has a depth scale 13 on both inner walls.
[0032] The depth scale 13 on both sides can help the doctor to keep the depth of both sides consistent during surgery.
[0033] In this embodiment, the width of the blade body 1 is a, which is 7-9mm; the width of the V-shaped blade body 11 is a1, which is 1.5-2.5mm; the height of the V-shaped blade body 11 is a2, which is 0.8-1.2mm; and the widths of the protective sheets 12 on both sides of the V-shaped blade body 11 are equal.
[0034] In this embodiment, the thickness of the blade body 1 is b, which is 0.3-0.7mm.
[0035] In this embodiment, the handle 2 is provided with anti-slip lines 4.
[0036] The anti-slip lines 4 on the handle increase the stability and comfort during surgery.
[0037] In this embodiment, the surgical knife is made of stainless steel.
[0038] The use of stainless steel has the characteristics of corrosion resistance, easy disinfection, high strength, etc., which is beneficial to ensure the long-term use and safety of surgical instruments.
[0039] In this embodiment, the protective sheets 12, the transition section 3 and the handle 2 are provided with round chamfers at the corners.
[0040] The round chamfers at the corners of the protective sheets 12, the transition section 3 and the handle 2 can reduce the risk of accidental injury during surgery and improve the safety of surgery.
[0041] The working principle of the meibomian wedge-shaped resection surgical knife is as follows:
[0042] During surgery, the V-shaped blade 15 of the surgical knife is aligned with the target area, and the length scale 14 on the protective sheet 12 is used for accurate positioning. The doctor controls the depth of resection along the depth scale 13, and uses the V-shaped blade 15 slowly and stably to resect the abnormal meibomian tissue in a wedge-shaped manner. The V-shaped design of the blade can evenly resect the tissue while reducing damage to the surrounding normal tissue. During the entire process, the doctor monitors the resection depth and range in real time by the scale mark on the blade body 1, ensuring the accuracy and symmetry of the surgery, and ultimately achieving the purpose of remodeling the meibomian structure and improving the meibomian function.
[0043] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
