Description

Technical Field

[0001] This utility model belongs to the field of tibialis anterior and fibula posterior, specifically relating to a clinical tibialis anterior and fibula measuring device. Background Technology

[0002] The clinical tibiofibular measuring device provides intraoperative information on the gap and traction between the tibiofibular joint. Clinicians use this device during surgery, applying appropriate traction, to assess the tibiofibular gap and determine the appropriate anatomical size as a basis for anatomical reduction.

[0003] A clinical tibiofibular measuring device (CN109330603A) is currently available, which can display the measured data intuitively on the scale and pressure gauge, facilitating medical staff to judge the reduction of the tibiofibular joint during surgery. However, the limiting component of this device uses a ratchet structure to fix the handle. Since there is a certain distance between two adjacent ratchet teeth, when the handle is between two adjacent ratchet teeth, the bottom of the handle can only be adjusted to the position of one of the ratchet teeth, resulting in a deviation in the position of the numerical indication and low precision in fixing the handle, which in turn affects the measurement accuracy. Therefore, a clinical tibiofibular measuring device is proposed to solve the above-mentioned problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 The clinical tibia and fibula measuring device in this embodiment has the advantage of good performance.

[0025] Specifically, it includes a support frame 1; the cross-section of the support frame 1 is U-shaped; the outer wall of the support frame 1 has scales 11; and the bottom left side of the support frame 1 has a fixing plate 12.

[0026] The sliding member 2 is slidably disposed inside the support frame 1; the outer wall of the sliding member 2 is provided with a pointer 7 opposite to the scale 11;

[0027] The driving component 3 is disposed on the outer wall of the support frame 1 and connected to the sliding component 2; the driving component 3 can drive the sliding component 2 to slide inside the support frame 1;

[0028] Handle 4 is located on the right side of the support frame 1, and a groove 41 is provided on the top of handle 4;

[0029] The guide 5 is slidably disposed inside the slide groove 41 and connected to the drive 3; the drive 3 drives the guide 5 when it rotates.

[0030] The fixing component 6 is set on the guide component 5 and extends through both sides of the guide component 5; the fixing component 6 is used to fix the guide component 5 and the drive component 3 in their current state.

[0031] In this embodiment, in the initial state, the pointer 7 on the slider 2 is at the zero point on the scale 11. When needed, the medical staff first holds the handle and presses the drive 3 with the palm. During this process, the drive 3 can push the slider 2 to slide inside the support frame 1 and drive the guide 5. At this time, the pointer 7 moves and changes its relative position with the scale 11. At this time, the medical staff can read the value according to the position indicated by the pointer 7. This value is the gap value of the lower tibia and fibula. After the measurement is completed, the fixing member 6 can be moved to fix the current state of the drive 3 and the guide 5.

[0032] Specifically, refer to Figure 1-2 The sliding member 2 includes a slider 21 slidably disposed inside the support frame 1; a measuring plate 22 disposed at the bottom of the slider 21 and sliding through the support frame 1; two rotating shafts 23 disposed on both sides of the slider 21 and sliding through the support frame 1; and a spring 24 disposed on the right side of the slider 21 and connected to the inside of the support frame 1.

[0033] Specifically, refer to Figure 1 The driving component 3 includes two connecting plates 31 respectively hinged to the outer walls of the two rotating shafts 23; a connecting plate 32 hinged to the right end of the connecting plate 31; the right end of the connecting plate 32 is hinged to the outer wall of the support frame 1 through the rotating shaft 33; and a pressure handle 34 connected at its lower end to the right end of the two connecting plates 32.

[0034] In this embodiment, when the pressure handle 34 is pressed, the connecting plate 2 32 rotates and gradually folds with the connecting plate 2 32 through the hinge point between them. Meanwhile, the measuring plate 22, the slider 21, and the rotating shaft 23 move laterally inside the support frame 1, gradually moving away from the fixing plate 12 and changing the position of the pointer 7. The fixing plate 12 and the measuring plate 22 allow medical personnel to easily insert the abutment directly into the tibiofibular gap for measuring the tibiofibular distance.

[0035] Specifically, refer to Figure 3 The guide 5 includes a slide seat 51 slidably disposed in the slide groove 41, with the two sides of the slide seat 51 sliding through the two sides of the handle 4 respectively; two hinge seats 52 respectively disposed on the top of the slide seat 51 and inside the pressure handle 34; the two hinge seats 52 are hinged together by a connecting rod 53.

[0036] Specifically, refer to Figure 4 The fixing component 6 includes a slide rod 61 that slides through the front and rear sides of the slide block 51; a fixing block 62 that is disposed at one end of the slide rod 61 and can abut against the outer wall of the handle 4; a pull block 63 that is hinged to the other end of the slide rod 61; a bearing ring 64 that is sleeved on the outer wall of the slide rod 61; and a spring 65 whose two ends are respectively connected to the bearing ring 64 and the inner wall of the slide block 51.

[0037] In this embodiment, when the pressure handle 34 is pressed down, the sliding block 51 slides inside the slide groove 41 through the push of the hinge seat 52 and the connecting rod 53. After the device completes the measurement, the pull block 63 can be pulled to rotate. When the pull block 63 changes from the longest side to the shortest side, it will pull the slide rod 61 to move forward and squeeze the spring 65. At the same time, the fixing block 62 gradually abuts against the outer wall of the handle 4. The current position of the sliding block 51 can be fixed by the friction between the fixing block 62 and the handle 4. After the sliding block 51 is fixed, the current state of the driving member 3 and the sliding member 2 can also be fixed. Compared with the ratchet fixing method in the prior art, the current measurement position can be fixed at any position. There will be no deviation in the measurement position caused by the ratchet tooth pitch, which will cause the value to deviate. At the same time, the fixing process can be completed by simply pulling and rotating the pull block 63. Compared with other fixing structures, it is more convenient and faster and more in line with clinical use scenarios.

[0038] Specifically, refer to Figure 4 A resistance-increasing pad 8 is provided on the contact surface between the fixing block 62 and the handle 4.

[0039] In this embodiment, the friction-increasing pad 8 can increase the friction between the fixing block 62 and the handle 4, thereby improving the fixing effect.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
