TECHNICAL FIELD
[0001] The present disclosure belongs to the technical field of medical devices, and particularly relates to a finger fracture fixator. BACKGROUND
[0002] In daily life, finger fracture is a common injury. In the follow-up care of patients with finger amputation or fracture in clinical treatment, the finger needs to be fixed so that the bone of the finger can be restored and healed to the original healthy state. The fracture is usually fixed by plaster. However, the plaster fixing on the finger is inconvenient to operate, not firm, easy to be infected, and the excessive external load will affect the patient's hand movement and the healing of the finger. Therefore, in view of the above, the existing structure and defects are improved, and a finger fracture fixator is provided, so as to achieve the purpose of being more practical.

The clamping plates can clamp and fix the finger fracture site, and the elastic fixing belts can be wound on the clamping plates to quickly and effectively fix the finger fracture site and promote fracture healing. At the same time, the elastic fixing belts can generate sustained pressure, which helps to keep the finger stable and reduce displacement.
[0004] The purpose of the present disclosure can be achieved by the following technical solutions:
[0005] A finger fracture fixator comprises:
[0006] At least two clamping plates, the outer sides of the two ends of the clamping plates are fixedly connected with a plurality of evenly distributed fixing stems, and the two clamping plates are used for clamping and fixing the finger fracture site;
[0007] An elastic fixing belt, the middle part of the elastic fixing belt is fixedly connected with the outer side of the middle part of the clamping plate, a plurality of evenly distributed fixing holes for the fixing stems to pass through are formed in the two ends of the elastic fixing belt, and the elastic fixing belt is spirally wound on the clamping plate to play a pressure fixing role.
[0008] The above technical solution has the following principles and technical effects:
[0009] The finger of the patient with fracture is placed between the two clamping plates, the two ends of the elastic fixing belt on each clamping plate are spirally wound on the two ends of the other clamping plate, and the elastic fixing belt is fixed by the fixing holes through which the fixing stems pass. The finger fracture site can be quickly and effectively fixed to promote fracture healing. At the same time, the elastic fixing belt can generate sustained pressure, which helps to keep the finger stable and reduce displacement.

[0018] Fixed connection refers to the connection of parts or components after being fixed, without any relative movement. It is divided into two kinds: detachable connection and non-detachable connection.
[0019] (1) Detachable connection is to fix parts together by using screw, spline, wedge tip, etc. This connection method can be disassembled during maintenance, and the parts will not be damaged. However, the specifications of the connecting parts must be correct (such as the length of the bolt, key, wedge tip), and the fastening should be appropriate.
[0020] (2) Non-detachable connection mainly refers to welding, riveting and over mortise fitting, etc. Because maintenance or replacement requires forging, sawing or oxygen cutting to disassemble, so the parts generally cannot be used twice. At the same time, attention should be paid to the process quality, technical detection and remedial measures (such as correction, polishing, etc.) during connection.
[0021] Threaded connection refers to the detachable connection of connecting parts by using threaded parts (or threaded parts of connected parts).
[0022] Sliding connection refers to the contact between two objects, but not fixed, and the two can slide relative to each other.
[0023] Rotary connection refers to the connection between parts that allows the parts to rotate relative to each other.
[0024] The beneficial effects of the present disclosure are:
[0025] 1. The splint can clamp and fix the fractured part of the finger, and the elastic fixing band can be wrapped around the splint, so as to quickly and effectively fix the fractured part of the finger and promote the healing of the fracture.
[0026] 2. The elastic fixing band can generate sustained pressure, which helps to keep the finger stable and reduce displacement.
[0027] 3. The fixator has the characteristics of quickness, effectiveness, simple operation and strong adaptability, and can be widely applied to hospitals, clinics and emergency scenes. BRIEF DESCRIPTION OF DRAWINGS
