Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to an adjustable tendon and ligament measuring device. Background Technology

[0002] A tendon measuring instrument is used to measure the length of tendons or muscles. It is mainly used in fields such as rehabilitation medicine, sports medicine, and clinical diagnosis and treatment to help doctors and rehabilitation therapists assess the muscle and tendon function of patients and provide a basis for developing treatment plans.

[0003] Currently, the mainstream tendon measuring instruments are long and block-shaped with measuring holes arranged sequentially. They are large and heavy, making them inconvenient to operate during surgery. In addition, because the tendon measuring instrument is designed as a whole, even when only a few specifications are needed, the entire measuring instrument must be used, which is very inconvenient. Its large size means it occupies a lot of space, making it inconvenient to operate during surgery. Furthermore, the tendon measuring instrument is not adjustable, which prevents flexible measurement. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable tendon and ligament measuring device, aiming to solve the problems of existing tendon measuring devices, which are long and bulky with measuring holes arranged sequentially. These devices are large and heavy, making them inconvenient for intraoperative operation. Furthermore, because the tendon measuring device is a single unit, even when only a few specifications are needed, the entire measuring device must be used, which is very inconvenient. Its large size also results in a large space occupation, hindering intraoperative operation. Additionally, the tendon measuring device is not adjustable, limiting its flexibility in measurement.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adjustable tendon and ligament measuring device includes:

[0007] First connecting cylinder;

[0008] Inner sleeve, which is fixedly connected to the upper end of the first connecting cylinder;

[0009] An adjustment knob is fitted onto the circumferential surface of the inner sleeve and is located at the upper end of the first connecting cylinder.

[0010] The second connecting cylinder is located at the upper end of the adjusting knob;

[0011] An adjustment mechanism includes an adjustment module, a placement slot, a connecting piece, a measuring cylinder, a rotating shaft, a sliding groove, and a mounting slot. Two rotating shafts and two mounting slots are provided. The measuring cylinder is located on the inner circumferential wall of the inner sleeve. The adjustment module is fitted onto the circumferential surface of the measuring cylinder. The placement slot is located at one end of the adjustment module. The connecting piece is rotatably connected to the placement slot. Both rotating shafts are fixedly connected to the connecting piece and pass through it. One rotating shaft is rotatably connected to the adjustment module. The sliding groove is located on the inner circumferential wall of the adjustment knob. Two mounting slots are located on the upper and lower inner walls of the sliding groove, respectively, at their adjacent ends. The other rotating shaft is rotatably connected to both mounting slots.

[0012] As a preferred embodiment of the present invention, a limiting ring is fixedly connected to the upper end of the first connecting cylinder, and a slot is provided at the lower end of the adjusting knob, with the limiting ring located in the slot.

[0013] As a preferred embodiment of the present invention, a limiting ring is fixedly connected to the upper end of the first connecting cylinder, and a slot is provided at the lower end of the adjusting knob, with the limiting ring located in the slot.

[0014] As a preferred embodiment of the present invention, the first connecting cylinder and the inner sleeve are integrally formed.

[0015] In a preferred embodiment of the present invention, the distance between the adjustment module and the groove on the inner wall of the first connecting cylinder is 0.2 cm.

[0016] As a preferred embodiment of the present invention, both the second connecting cylinder and the first connecting cylinder are fitted with anti-slip sleeves on their circumferential surfaces, and the surfaces of the anti-slip sleeves are made of frosted material.

[0017] In a preferred embodiment of the present invention, the far ends of the second connecting cylinder and the first connecting cylinder are both planar.

[0018] In a preferred embodiment of the present invention, the rotation radius of the connecting piece is degrees.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. Rotate the adjustment knob. The adjustment knob and the adjustment module are connected by a connecting piece and a rotating shaft to form a simple linkage slider mechanism. Rotating the adjustment knob can adjust the diameter of the measuring cylinder at the front of the adjustment module. The measuring cylinder is made of spring steel sheet and can change its diameter under the squeezing or pulling action of the adjustment module, thereby achieving the function of adjusting the size. During measurement, the tendon braid to be measured is passed through the measuring cylinder to measure the size of the tendon braid. This makes the device adjustable, convenient to use and carry, and more flexible in operation.

[0021] 2. Personnel can judge the radius of the internal measuring cylinder by observing the scale. This helps to remind personnel that when the first indicator arrow reverses along with the scale, personnel can observe whether the device has returned to its original position by checking the alignment of the first and second indicator arrows. This prevents excessive or insufficient reversal and facilitates personnel observation.

[0022] 3. The first connecting cylinder and the inner sleeve are integrally molded, which can reduce the assembly error between parts, thereby improving the performance and reliability of the entire equipment and reducing the complexity of the assembly process. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figures 1-7 The present invention provides the following technical solutions:

[0035] An adjustable tendon and ligament measuring device includes:

[0036] First connecting cylinder 3;

[0037] Inner sleeve 7, which is fixedly connected to the upper end of the first connecting cylinder 3;

[0038] Adjusting knob 1 is fitted onto the circumferential surface of the inner sleeve 7 and is located at the upper end of the first connecting cylinder 3.

[0039] The second connecting cylinder 2 is located at the upper end of the adjusting knob 1;

[0040] The adjustment mechanism includes an adjustment module 8, a placement groove 9, a connecting piece 10, a measuring cylinder 11, a rotating shaft 12, a sliding groove 14, and a mounting groove 16. Two rotating shafts 12 and two mounting grooves 16 are provided. The measuring cylinder 11 is located on the inner circumference of the inner sleeve 7. The adjustment module 8 is fitted onto the circumference of the measuring cylinder 11. The placement groove 9 is located on one side of the adjustment module 8. The connecting piece 10 is rotatably connected to the placement groove 9. Both rotating shafts 12 are fixedly connected to and pass through the connecting piece 10. One rotating shaft 12 is rotatably connected to the adjustment module 8. The sliding groove 14 is located on the inner circumference of the adjustment knob 1. Two mounting grooves 16 are located on the upper and lower inner walls of the sliding groove 14, respectively, at their adjacent ends. The other rotating shaft 12 is rotatably connected to both mounting grooves 16.

[0041] In a specific embodiment of the present invention, the measuring cylinder 11 is C-shaped. The device includes six sets of adjusting modules 8, connecting pieces 10, and two rotating shafts 12. The other end of each adjusting module 8 has a C-shaped groove, allowing it to be secured to the circumferential surface of the measuring cylinder 11. Sufficient distance is maintained between each adjusting module 8. During manufacturing, one rotating shaft 12 is inserted into the placement groove 9, allowing the connecting piece 10 to move left and right within the groove. The other rotating shaft 12 is inserted into the mounting groove 16 to ensure the connecting piece 10 moves within the adjusting knob 1. This also allows for the connection... The plate 10 is positioned to limit its rotation angle, preventing it from falling off or becoming misaligned. At this time, the adjustment knob 1 is fitted around the circumferential surface of the measuring cylinder 11, enclosing the adjustment module 8 and the measuring cylinder 11. In this device, the inner circumferential walls of both the first connecting cylinder 3 and the second connecting cylinder 2 have six grooves, and the circumferential surface of the inner sleeve 7 has six hollow slots. The first connecting cylinder 3 and the inner sleeve 7 are integral. After picking up the first connecting cylinder 3 and inserting the corresponding adjustment module 8 into the corresponding groove, the inner sleeve 7, due to its thinness, will be positioned inside the adjustment knob 1. The second connecting cylinder 2 is welded to the top of the inner sleeve 7, making the first connecting cylinder 3, the inner sleeve 7, and the second connecting cylinder 2 a single unit. This completes the installation of the device, making it ready for use. In use, after stabilizing the device by holding the adjustment knob 1 with one hand, freely rotating the second connecting cylinder 2 or the first connecting cylinder 3 will cause the internal adjustment module 8 to swing. Alternatively, the second connecting cylinder 2 can be held while rotating the adjustment knob 1 alone to rotate the device. Due to the limitation imposed by the rotating shaft 12, the left and right swing of the connecting piece 10 is restricted, thus preventing misalignment. With the adjustment module 8 and the measuring cylinder 11 tightly engaged, the measuring cylinder 11 will tighten when rotated. During measurement, the tendon braid to be measured is passed through the measuring cylinder 11 to measure the size of the tendon braid, thus achieving the measurement function. By randomly rotating the second connecting cylinder 2 or the first connecting cylinder 3, the adjustment module 8 is driven to compress the radius of the measuring cylinder 11, which can be reduced. The height of this device can be set to a length of 20-25cm to control the volume, making it convenient to carry, handle, and operate during surgery. Adjusting the radius of the measuring cylinder 11 makes the actual operation of the device more flexible and simple to operate.

[0042] Please refer to the details. Figures 3-7 The upper end of the first connecting cylinder 3 is fixedly connected to a limiting ring 13, and the lower end of the adjusting knob 1 is provided with a slot 15, in which the limiting ring 13 is located.

[0043] In this embodiment: during docking, the limiting ring 13 at the upper end of the first connecting cylinder 3 will enter the slot 15, which can stabilize the device, reduce the shaking amplitude and tilt, and reduce the gap between them, so that the device is installed stably.

[0044] Please refer to the details. Figure 1The circumferential surface of the adjusting knob 1 is adhesively connected to a second indicator arrow 6, the circumferential surface of the second connecting cylinder 2 is fitted with a scale 4, and the circumferential surface of the second connecting cylinder 2 is adhesively connected to a first indicator arrow 5.

[0045] In this embodiment: the device has two sets of first indicator arrow 5, second indicator arrow 6 and scale 4. When the second connecting cylinder 2 or the first connecting cylinder 3 rotates, the position of the second indicator arrow 6 can be used to observe the scale 4 to determine the radius of contraction of the measuring cylinder 11 inside, which is convenient for reminding personnel. When the first indicator arrow 5 reverses along with the scale 4, the personnel can observe whether the device has returned to its original position by observing the alignment of the first indicator arrow 5 and the second indicator arrow 6, which prevents excessive or insufficient reversal and facilitates personnel observation.

[0046] Please refer to the details. Figure 3 The first connecting cylinder 3 and the inner sleeve 7 are integrally molded.

[0047] In this embodiment, the first connecting cylinder 3 and the inner sleeve 7 are integrally molded, which can reduce the assembly error between parts, thereby improving the performance and reliability of the entire equipment, reducing the complexity of the assembly process, and improving production efficiency.

[0048] Please refer to the details. Figure 1 The distance between the adjustment module 8 and the groove on the inner wall of the first connecting cylinder 3 is 0.2cm.

[0049] In this embodiment: after the adjustment module 8 is installed, there is a 0.2cm gap between it and the groove on the inner wall of the first connecting cylinder 3, providing sufficient space to achieve precise adjustment. The 0.2cm gap design makes the design have good compatibility.

[0050] Please refer to the details. Figure 1 The circumferential surfaces of the second connecting cylinder 2 and the first connecting cylinder 3 are both fitted with anti-slip sleeves 17, and the surface of the anti-slip sleeves 17 is made of frosted material.

[0051] In this embodiment:

[0052] Please refer to the details. Figure 1 The far ends of the second connecting cylinder 2 and the first connecting cylinder 3 are both designed as planes.

[0053] In this embodiment, the far ends of the second connecting cylinder 2 and the first connecting cylinder 3 are both designed as flat surfaces, which ensures that the device remains stable and does not shake when it is in use or when it is temporarily placed.

[0054] Please refer to the details. Figure 4 The rotation radius of connecting piece 10 is 30 degrees.

[0055] In this embodiment, the maximum rotation radius of the connecting piece 10 is 30 degrees. This limits the shrinkage position of the measuring cylinder 11, preventing it from being squeezed or deformed due to excessive shrinkage, thus protecting its stable use and increasing its service life.

[0056] The working principle and usage process of this invention are as follows: After determining the required size, adjust the tendon measuring device to the required size, and then measure the braided tendon. First, rotate the adjustment knob 1. The adjustment knob 1 and the adjustment module 8 are connected through the connecting piece 10 and the rotating shaft 12 to form a simple linkage slider mechanism. Rotating the adjustment knob 1 can adjust the diameter of the measuring cylinder 11 at the front end of the adjustment module 8. The measuring cylinder 11 is made of spring steel sheet and has an open design. Its diameter can be changed under the squeezing or pulling action of the adjustment module 8, thereby achieving the function of adjusting the size. During measurement, the braided tendon to be measured is passed through the measuring cylinder 11 to measure the size of the braided tendon. The height of this device can be set to a length of 20-25cm to control the volume and facilitate carrying, handling and intraoperative operation. Adjusting the radius of the measuring cylinder 11 makes the actual operation of the device more flexible and simple to operate.

[0057] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
