In addition, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the embodiments of the utility model can be understood according to the specific circumstances.

[0020] The utility model embodiment provides a kind of zygomatic arch fracture reduction instrument, including working part 1, handle 3, endoscope channel 4, aspirator channel 5 and two arc-shaped strippers 2;Working part 1 is U type structure, two arc-shaped strippers 2 are symmetrically arranged relative to working part 1, and two arc-shaped strippers 2 are all connected to one end of working part 1, and the other end of working part 1 is connected with handle 3;Arc-shaped stripper 2 is arc structure, arc-shaped stripper 2 is configured to strip zygomatic arch deep surface periosteum and tendon attachment;The two sides of working part 1 are all connected with endoscope channel 4;The two sides of working part 1 are all connected with aspirator channel 5.

[0021] For example, handle 3 is used for doctor to hold and operate the whole instrument, and the design of handle 3 conforms to the ergonomic principle, to ensure that doctor can maintain comfortable holding feeling during long time operation process, reduce hand fatigue.In addition, control button or switch can also be provided on handle 3, for adjusting the focal length, brightness of endoscope or starting suction function, to improve the convenience of operation.

[0022] Exemplarily, the working part 1 is the core part of the entire instrument, adopts a U-shaped structure design, and provides stable support and an operation platform for the entire instrument. This design not only facilitates the operation of the doctor during the operation process, but also effectively reduces the shaking of the instrument during the operation process, improves the stability and safety of the operation.

[0023] Exemplarily, two arc-shaped elevators 2 are symmetrically arranged at one end of the working part 1, which can accurately strip the periosteum and tendon attachment of the deep surface of the malar arch, so that the fracture end can be fully exposed. The design of the arc-shaped elevator 2 fully considers the anatomical characteristics of the malar arch, so that the stripping process is more smooth and efficient, and the damage to the surrounding tissues is reduced.

[0024] Exemplarily, the working part 1 is a U-shaped flat structure.

[0025] Exemplarily, when the reduction of the malar arch fracture is performed, the arc-shaped elevator 2 penetrates into the deep surface of the malar arch fracture end, and the working part 1 is located outside the wound. When the reduction is performed, the medical staff holds the working part 1 to pull up and reduce. Compared with the traditional reduction method, the use of the reduction instrument of the present application is more conducive to the effective and stable force of the medical staff on the fracture end.

[0026] In the embodiment of the present application, an endoscope is also included; the endoscope is arranged in the endoscope channel 4, and the endoscope is configured to visually observe the fracture end.

[0027] Exemplarily, the doctor observes the reduction condition of the fracture end in real time through the endoscope during the operation process, to ensure the accuracy and integrity of the reduction. The introduction of the endoscope greatly improves the visualization degree of the operation, so that the doctor can perform the operation under a clearer visual field, and reduces the operation risk.

[0028] Exemplarily, the suction channel 5 is connected with a suction device, which is used to timely remove blood, exudate and the like in the operation field during the operation process, to maintain the clarity of the operation field. The use of the suction device not only improves the operation efficiency, but also reduces the operation errors caused by the blur of the operation field.

[0029] In the embodiment of the present application, the arc-shaped elevator 2 is bent to one side of the working part 1, and the included angle between the arc-shaped elevator 2 and the working part 1 is 45°.

[0030] Exemplarily, the arc-shaped lifter 2 is designed to be bent at an angle of 45° to one side of the working part 1. The angle is selected based on in-depth research on the anatomy of the zygomatic arch region, aiming to enable the lifter to more naturally fit and penetrate to the deep surface area of the zygomatic arch, thereby effectively lifting the periosteum and tendon attachment and reducing damage to the surrounding tissues. The 45° included angle not only provides sufficient operating space, but also enables the surgeon to more flexibly adjust the position and direction of the lifter during the operation to adapt to the anatomical variations and fracture conditions of different patients.

[0031] In the embodiment of the present application, the handle 3 is provided with stripes.

[0032] Exemplarily, by increasing the stripes on the handle 3, the contact area between the hand and the handle 3 can be significantly increased, and the friction of the contact surface can be increased; the stripes can be made of rubber, silicone or other anti-slip materials, which not only have good touch, but also can effectively prevent the hand from slipping in long-time holding or wet environment.

[0033] In the embodiment of the present application, both sides of the arc-shaped lifter 2 are arc-shaped surfaces, and the two arc-shaped surfaces intersect into a sharp end away from the end of the working part 1, and the sharp end is polished into a blunt round structure.

[0034] Exemplarily, the sharp end of the lifter is designed to be blunt or slightly beveled to avoid piercing important structures such as blood vessels or nerves during the lifting process, ensuring the safety of the operation.

[0035] In the embodiment of the present application, the arc-shaped lifter 2 is made of stainless steel or titanium alloy material.

[0036] Exemplarily, the arc-shaped lifter 2 is made of high-strength, corrosion-resistant medical-grade stainless steel or titanium alloy material, which can ensure its stability and durability during the operation. Further, the surface of the arc-shaped lifter 2 is polished, which can reduce the friction and damage to the soft tissue, and at the same time increase the smoothness of the instrument, facilitating the operation of the doctor.

[0037] Each embodiment in the specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other, and each embodiment focuses on the difference from other embodiments.

[0038] The above embodiments are only used to illustrate the technical solutions of the present application, and are not limited to the present application; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the present application.
