Description

Technical Field

[0001] The utility model belongs to the technical field related to medical instruments, and particularly relates to a double-joint orthopedic measuring ruler. Background Art

[0002] The function of a joint is to provide movement while preventing excessive movement or movement in the wrong direction. Therefore, movement of a joint beyond the limit point will cause excessive wear of the cartilage and ligaments around the joint, making people more susceptible to injury. A double joint is two bone spheres connected to two joint points. Therefore, a corresponding measuring ruler will be used when measuring a double joint in orthopedics.

[0003] However, the existing measuring rulers do not have the function of facilitating angle rotation, so they cannot quickly measure the bending angle of the joint, which will affect the operation of the user. At the same time, when using the measuring ruler for work, since it does not have the function of measuring limit, the stability of the measurement process cannot be guaranteed. To this end, we provide a double-joint orthopedic measuring ruler to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a double-joint orthopedic measuring ruler, which can quickly measure the bending angle of the joint by rotating the rotating ring plate around the rotating drum and driving the movement of the rotating bar. At the same time, the adsorption between the magnetic plate and the metal plate can ensure the stability of the measuring process.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a double-joint orthopedic measuring ruler, comprising an angle measuring ring; a rotating cylinder is fixed at the middle position of the angle measuring ring, a rotating ring plate is sleeved on the axial end of the rotating cylinder, a rotating bar is fixed on the circumference of the rotating ring plate, and the two rotating bars are arranged in a staggered manner; a baffle plate connected with the end face of the rotating cylinder is fixed on the inner side wall of the rotating ring plate, a rotating opening is opened on both end faces of the rotating cylinder, an abutment ring rotating at the inner position of the rotating opening is fixed on the inner end face of the baffle plate, a metal ring plate connected with the inner side wall of the rotating cylinder is fixed on the other end of the abutment ring, a pressing round block is slidably arranged inside the baffle plate, and a magnetic plate adsorbed with the metal ring plate is fixed on the end of the pressing round block.

[0007] The utility model is further configured that a connecting ring connected to the peripheral side of the rotating drum is fixed to the end face of the baffle plate close to the angle measuring ring, and a movable ring connected to the end face of the angle measuring ring is fixed to the other end face of the connecting ring.

[0008] The utility model is further configured that finger strips are fixed on the peripheral sides of the movable ring, and the finger strips are slidably fitted on the peripheral sides of the movable ring.

[0009] The utility model is further configured such that the peripheral side of the magnetic plate is in sliding contact with the inner side wall of the rotating drum, and the end surface of the pressing round block is flush with the end surface of the baffle plate.

[0010] The utility model is further configured that a partition is fixed at the middle position of the inner side of the rotating drum, and the diameter of the rotating opening is smaller than the diameter of the rotating drum.

[0011] The utility model is further configured that a spring is fixed to the end surface of the magnetic plate relative to the partition plate, and the other end of the spring is fixed to the position of the end surface relative to the partition plate.

[0012] The utility model is further configured such that the width of the abutting ring is consistent with the width of the turning opening, and the peripheral side of the movable ring is flush with the peripheral side of the angle measuring ring.

[0013] The utility model has the following beneficial effects:

[0014] 1. When the utility model is in use, the angle measuring ring is set at the bending position of the joint. Therefore, when the joint is bent, the joint position will drive the two rotating bars to rotate, and the rotating bars will drive the rotating ring plate to rotate at the peripheral position of the rotating drum. At the same time, according to the rotation angle between the two rotating bars, the bending angle of the joint can be directly measured, thereby improving the measurement efficiency.

[0015] 2. When the utility model is in use, through the adsorption relationship between the magnetic ring and the metal ring plate, the pressing round block is controlled to move in the internal position of the rotating port, thereby the pressing round block will drive the magnetic plate and the metal ring plate to break away from the adsorption relationship, and the rotating ring plate can be rotated around the circumferential position of the rotating cylinder. At the same time, when it is necessary to ensure that the rotating ring plate does not rotate at will, the pressing round block can be released, thereby causing the magnetic plate to be adsorbed with the metal ring plate again, thereby ensuring the stability of the rotating ring plate, thereby ensuring the stability of the measuring process.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] 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 of 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.

[0026] Example 1

[0027] See also Figures 1 to 5 The utility model is a double-joint orthopedic measuring ruler. The rotating ring plate 2 rotates around the rotating drum 101 and drives the movement of the rotating bar 3, so as to quickly measure the bending angle of the joint. At the same time, the adsorption between the magnetic plate 401 and the metal plate can ensure the stability of the measuring process.

[0028] Specifically, the angle measuring ring 1; a rotating drum 101 is fixed in the middle position of the angle measuring ring 1, and the axial ends of the rotating drum 101 are sleeved with rotating ring plates 2, and rotating bars 3 are fixed on the circumference of the rotating ring plate 2, and the two rotating bars 3 are staggered. A baffle plate 201 connected to the end face of the rotating drum 101 is fixed to the inner wall of the rotating ring plate 2, and a rotating opening 103 is opened on both end faces of the rotating drum 101. An abutment ring 202 rotating in a position inside the rotating opening 103 is fixed to the inner end face of the baffle plate 201, and a metal ring plate 203 connected to the inner wall of the rotating drum 101 is fixed to the other end of the abutment ring 202, and a pressing round block 4 is slidably arranged inside the baffle plate 201, and a magnetic plate 401 adsorbed to the metal ring plate 203 is fixed to the end of the pressing round block 4.

[0029] The operation process of this embodiment is as follows: through the setting and use of the above-mentioned structure, when it is necessary to measure the bending angle of the double joints, the protractor ring 1 is set at the bending position of the joint. Therefore, when the joint is bent, the joint position will drive the two rotating bars 3 to rotate, thereby the rotating bars 3 will drive the rotating ring plate 2 to rotate at the peripheral position of the rotating drum 101. At the same time, according to the rotation angle between the two rotating bars 3, the bending angle of the joint can be directly measured, and through the adsorption relationship between the magnetic ring and the metal ring plate 203, by controlling the pressing circle 4 to move in the internal position of the rotating port 103, the pressing circle 4 will drive the magnetic plate 401 and the metal ring plate 203 to break away from the adsorption relationship. At this time, the rotating ring plate 2 can be rotated around the peripheral position of the rotating drum 101. At the same time, when it is necessary to ensure that the rotating ring plate 2 does not rotate at will, the pressing circle 4 can be released, thereby causing the magnetic plate 401 to be adsorbed with the metal ring plate 203 again, thereby ensuring the stability of the rotating ring plate 2.

[0030] Furthermore, a connecting ring 204 connected to the circumference of the rotating drum 101 is fixed to the end face of the retaining ring plate 201 close to the protractor ring 1, and a movable ring 205 connected to the end face of the protractor ring 1 is fixed to the other end face of the connecting ring 204, and a finger strip 206 is fixed to the circumference of the movable ring 205, and the finger strip 206 slides and fits on the circumference of the movable ring 205, the width of the abutment ring 202 is consistent with the width of the rotating mouth 103, and the circumference of the movable ring 205 is flush with the circumference of the protractor ring 1, and when the rotating ring plate 2 rotates, the rotating ring plate 2 will drive the finger strip 206 to rotate through the connecting ring 204 and the movable ring 205, so the user can check the angle between the two finger strips 206 according to the protractor ring 1.

[0031] Example 2

[0032] See also Figure 3 , Figure 4 and Figure 5 On the basis of Example 1, the magnetic plate 401 can be stably adsorbed and connected to the metal ring plate 203 by the spring 402 pushing the magnetic plate 401.

[0033] Specifically, the circumferential side of the magnetic plate 401 is slidably connected with the inner wall of the rotating drum 101, the end face of the pressing block 4 is flush with the end face of the retaining ring plate 201, a partition 102 is fixed in the middle position of the inner side of the rotating drum 101, the diameter of the rotating mouth 103 is smaller than the diameter of the rotating drum 101, and a spring 402 is fixed to the end face of the magnetic plate 401 relative to the partition 102, and the other end of the spring 402 is fixed to the end face position opposite to the partition 102.

[0034] The operation process of this embodiment is: the spring 402 is limited by the partition 102, so after controlling the pressing ball 4 to move in the internal position of the turning mouth 103, the magnetic plate 401 will be controlled to compress the spring 402. It can be seen that after releasing the pressing ball 4, the spring 402 at this time will directly push the magnetic plate 401 to move the rod away from the partition 102, so that the magnetic plate 401 will be re-adsorbed with the metal ring plate 203.
