Description

Technical Field

[0001] The utility model relates to the technical field of fixators, in particular to an ankle joint scanning fixator. Background Art

[0002] Human ankle joint scanning often refers to CT testing, which has become one of the important means of diagnosing diseases. During the testing process, the testing instrument is generally used to scan back and forth at the ankle joint. Finally, the computer screens the scanned image and displays the screened image on the scanning device for easy observation by the testing personnel.

[0003] There are still some shortcomings in the use of current CT scanning devices: when traditional CT scanning devices scan the ankle joint, the patient himself needs to deliberately keep the ankle joint symmetrical for detection and scanning. Since the ankle joints on both sides of ordinary people generally expand from the inside to the outside, this detection method can easily lead to asymmetry in the scanned ankle joint scan, thereby affecting the doctor's diagnosis.

[0004] Therefore, an ankle joint scanning fixator is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1-4The utility model provides a technical solution: an ankle joint scanning fixer comprises a mounting plate 1; a sliding opening 2 is provided on the left side of the upper surface of the mounting plate 1, a fixing plate 3 is installed on the left side of the upper surface of the mounting plate 1, two sliders 4 are slidably installed on the inner wall of the sliding opening 2, a bidirectional screw rod 5 is commonly threadedly installed on the inner walls of the two sliders 4, a concave plate 6 is commonly rotatably installed on the front and rear ends of the bidirectional screw rod 5, the upper side surface of the concave plate 6 is fixed to the upper part of the inner wall of the mounting plate 1, a first motor 7 is installed on the front end of the bidirectional screw rod 5, a fixing rod 8 is installed on the opposite side surfaces of the two sliders 4, the opposite ends of the two fixing rods 8 penetrate one side of the outer wall of the fixing plate 3 and extend to the inside, a limiting cylinder 9 is installed on the opposite ends of the two fixing rods 8, and the insides of the two limiting cylinders 9 are provided with a buffer A punch assembly is provided, a threaded hole 15 is provided on the left side of the inner wall of the fixing plate 3, and a pushing assembly is provided on the inner wall of the threaded hole 15. A placing table 19 is installed below the inner wall of the fixing plate 3, and placing grooves 20 are provided on the front and rear sides of the upper surface of the placing table 19. By controlling the rotation of the first motor 7 before scanning, the sliders 4 on both sides are driven to move along the inner wall of the fixing plate 3, and the first airbags 14 on both sides are driven to push the patient's ankle joint for correction, and the limit spring 10 is cooperated to prevent pain to the patient. The screw 16 is rotated and the second support plate 17 and the second airbag 18 are pushed to further correct the sole of the ankle joint, ensuring that the ankle joints on both sides are basically consistent, thereby improving the symmetry of the scanning results of the ankle joints on both sides, and also facilitating the later examination of the physician.

[0023] like Figure 2 As shown, in order to further ensure the consistency of the ankle joints on both sides, the pushing component includes a screw 16, the rod wall of the screw 16 is threadedly connected to the inner wall of the threaded hole 15, and a second support plate 17 is installed at the right end of the threaded hole 15. A second airbag 18 is installed on the right surface of the second support plate 17, and two limit rods are installed on the left surface of the second support plate 17. The left ends of the two limit rods pass through the left side of the inner wall of the fixing plate 3 and extend to the outside. A turning handle is installed at the left end of the screw 16. The screw 16 is driven to rotate together by manually turning the handle, and the moving position of the second support plate 17 is limited by the limiting rod, thereby driving the screw 16 to rotate while pushing the second support plate 17 and the second airbag 18 to move to the right, so that the ankle joint position remains in a consistent shape while moving, so that the scanned data is more convenient for comparison and observation.

[0024] The working principle is as follows: the device automatically adjusts and corrects the ankle joint, so that the scanned data can be more detailed and convenient for the operator to analyze and operate. When in use, the patient is first allowed to sit on the mounting plate 1, and then the ankle joint is placed inside the placement slot 20. At this time, the device automatically controls the first motor 7 to start rotating, thereby driving the bidirectional screw rod 5 to rotate together, and while rotating, the outer wall of the slider 4 is limited by the sliding opening 2, thereby driving the sliders 4 on both sides to move in relative or opposite directions along the inner wall of the sliding opening 2, and while moving, the first support plates 13 and the first airbags 14 on both sides are driven to push the patient's ankle joint for correction to meet the scanning standard, and at the same time, the limit springs 10 are pushed by the sliding blocks 11 on both sides for contraction and buffering to prevent secondary injuries to the patient during the correction process, and the pressure sensor 12 is used to conveniently record the force applied to the ankle joint each time, so as to facilitate the next detection.

[0025] To ensure that the scanned shapes of the ankle joints on both sides are basically consistent, after the side adjustments of the ankle joints are completed, the screw 16 is driven to rotate together by manually turning the handle, and the movement position of the second support plate 17 is limited by the limit rod, thereby driving the screw 16 to rotate while pushing the second support plate 17 and the second airbag 18 to move to the right. While moving, the ankle joint position maintains a consistent shape, making it easier to compare and observe the scanned data, and convenient for later operators to check.

A moving opening 23 is opened on the right side of the upper surface of the mounting plate 1, and a moving block 24 is installed on the lower surface of the backrest plate 22. The outer part of the moving block 24 is slidably installed on the inner wall of the moving opening 23. A threaded rod 25 is threadedly installed on the inner wall of the moving block 24. The left and right ends of the threaded rod 25 are rotatably installed on the left and right sides of the inner wall of the mounting plate 1 respectively. The right end of the threaded rod 25 passes through the right side of the inner wall of the mounting plate 1 and extends to the outside. The threaded rod 25 5 is installed with a second motor 26, the left side surface of the second motor 26 is fixed to the right side surface of the mounting plate 1, and the patient can lean on the backrest plate 22 to facilitate the scanning operation, and then the second motor 26 is controlled to rotate to drive the threaded rod 25 to rotate, thereby driving the moving block 24 to slide along the inner wall of the moving opening 23, and the backrest plate 22 is driven to move together while moving, and the moving position of the backrest plate 22 is limited by the sliding grooves 21 on both sides, thereby improving the stability of the moving position of the backrest plate 22, thereby facilitating the detection of people of different heights and improving the practicality of the device.
