Description

Technical Field

[0001] The utility model relates to the technical field of arthroscopes, and particularly relates to a three-dimensional space distance measuring device under an arthroscope. Background Technique

[0002] An arthroscope is a rod-shaped optical instrument with a diameter of about 5 mm for observing the internal structure of a joint. It is an endoscope used for diagnosing and treating joint diseases. An arthroscope is equipped with a lens at the end of a thin tube. When the thin tube is inserted into the joint, the internal structure of the joint will be displayed on the monitor. Therefore, the internal structure of the joint can be directly observed. The arthroscope is not only used for disease diagnosis, but has also been widely used in the treatment of joint diseases.

[0003] When the existing arthroscope is used to detect and observe ankle joint lesions, there is a lack of a structure for measuring the length of the lesion, resulting in doctors having to estimate through the imaging on the monitor, which may lead to deviations in the subsequent treatment process. Based on the existing technical deficiencies, the utility model designs a three-dimensional space distance measuring device under an arthroscope. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a three-dimensional space distance measuring device under an arthroscope, which has the advantage of measuring the length of the lesion of the ankle joint.

[0005] The utility model provides the following technical solution: A three-dimensional space distance measuring device under an arthroscope includes the head of the arthroscope main body. On one side of the outer surface of the head of the arthroscope main body, a measuring structure is arranged. The measuring structure includes a measuring tube, and a driving structure is installed on the top of the measuring tube; a scale is arranged on one side of the outer surface of the measuring tube, a pushing tube is slidably clamped inside the measuring tube, a connecting block is installed at one end of the pushing tube in a threaded manner, and a plurality of tooth blocks are installed on the top of the pushing tube; the driving structure includes two arc-shaped blocks and a threaded rod. A fixed shaft is installed on one side of one of the arc-shaped blocks, a knob rod is rotatably installed inside the fixed shaft, a gear is installed at one end of the knob rod, and the outer surface of the gear meshes with the tooth blocks.

[0006] As a preferred technical solution of the utility model, a protective shell is installed on the top of the two arc-shaped blocks, and the threaded rod is in threaded connection with the protective shell.

[0007] As a preferred technical solution of the utility model, a clamping plate is rotatably installed at one end of the threaded rod, and the bottom teeth of the clamping plate mesh with the outer surface of the gear.

[0008] As a preferred technical solution of the present utility model, a rotating handle is installed at one end of the outer surface of the threaded rod, and two limiting rods are installed on one side of the outer surface of the clamping plate, and the two limiting rods are movably connected to the protective shell.

[0009] As a preferred technical solution of the present utility model, an arthroscope body probe is movably installed inside the head of the arthroscope body, and one end of the arthroscope body probe is fixedly connected to a connecting block.

[0010] As a preferred technical solution of the present utility model, a rear support is installed at one end of the outer surface of the measuring tube, and a tension spring is installed inside the cavity of the rear support.

[0011] As a preferred technical solution of the present utility model, one end of the tension spring is fixedly connected to the push tube.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. For this arthroscopic three-dimensional space distance measuring device, through the measuring structure and the driving structure, when the arthroscope body probe is inserted into the patient's ankle joint, the internal part is observed and examined through the lens inside the arthroscope body probe. When it is necessary to measure the patient's diseased area, by rotating the knob rod, the gear is driven to rotate. Since the outer surface of the gear meshes with the outer surface of the tooth block, the push tube can be made to push the arthroscope body probe to move at the patient's diseased area through the connecting block. Since the length of the arthroscope body probe is the same as the length of the push tube, by observing the length of the push tube moving on one side of the tooth block, the length of the patient's lesion can be measured, thereby achieving the purpose of facilitating the measurement of the length of the internal lesion of the patient's ankle joint;

[0014] 2. For this arthroscopic three-dimensional space distance measuring device, through the driving structure, when the push tube pushes the arthroscope body probe to measure the diseased area through the connecting block, by rotating the limiting rod, due to the limitation of the two threaded rods on both sides, the threaded rod can rotate and move in the protective shell, driving the clamping plate to move forward, so that the clamping plate can clamp and fix the gear, thereby avoiding the knob rod being accidentally touched and causing the push tube to move again, which affects the measured length. After the measurement is completed, the clamping plate needs to be reset, and at this time, the tension spring can pull the push tube to reset it. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , an arthroscopic three-dimensional space distance measuring device, including the head 1 of the arthroscope main body. On one side of the outer surface of the head 1 of the arthroscope main body, a measuring structure 2 is provided. The measuring structure 2 includes a measuring tube 21. At the top of the measuring tube 21, a driving structure 3 is installed; on one side of the outer surface of the measuring tube 21, a scale 22 is provided. Inside the measuring tube 21, a pushing tube 23 is slidably clamped. One end of the pushing tube 23 is threadedly installed with a connecting block 24. At the top of the pushing tube 23, a plurality of toothed blocks 25 are installed; the driving structure 3 includes two arc-shaped blocks 31 and a threaded rod 35. On one side of one of the arc-shaped blocks 31, a fixed shaft 32 is installed. Inside the fixed shaft 32, a knob rod 33 is rotatably installed. At one end of the knob rod 33, a gear 34 is installed. The outer surface of the gear 34 meshes with the toothed block 25.

[0022] Please refer to Figures 3-4 , on the top of the two arc-shaped blocks 31, a protective shell 6 is installed. The threaded rod 35 is threadedly connected to the protective shell 6. One end of the threaded rod 35 is rotatably installed with a clamping plate 36. The bottom teeth of the clamping plate 36 mesh with the outer surface of the gear 34. On one end of the outer surface of the threaded rod 35, a turning handle 37 is installed. On one side of the outer surface of the clamping plate 36, two limiting rods 38 are installed. The two limiting rods 38 are movably connected to the protective shell 6. Inside the head 1 of the arthroscope main body, a probe 5 of the arthroscope main body is movably installed. One end of the probe 5 of the arthroscope main body is fixedly connected to the connecting block 24.

[0023] When the push tube 23 pushes the arthroscope body probe 5 through the connecting block 24 to measure the lesion, by rotating the limiting rod 38, due to the limitation of the two threaded rods 35, when the threaded rods 35 rotate and move in the protective shell 6, the clamping plate 36 can be driven to move forward, so that the clamping plate 36 can clamp and fix the gear 34, thus avoiding the push tube 23 from moving again due to the accidental touch of the knob rod 33, which affects the measured length.

[0024] Please refer to Figures 1-4 One end of the outer surface of the measuring tube 21 is provided with a rear support tube 4, and a tension spring 41 is installed in the inner cavity of the rear support tube 4. One end of the tension spring 41 is fixedly connected to the push tube 23.

[0025] After the measurement is completed, the clamping plate 36 needs to be reset. At this time, the tension spring 41 can pull the push tube 23 to reset it.

[0026] Working principle: When an arthroscopic three-dimensional space distance measuring device is in use, in the initial state, first, the arthroscope body probe 5 is inserted into the patient's ankle joint, and the inside is observed and examined through the lens inside the arthroscope body probe 5. When it is necessary to measure the patient's lesion, by rotating the knob rod 33, the gear 34 is driven to rotate. Since the outer surface of the gear 34 meshes with the outer surface of the tooth block 25, the push tube 23 can push the arthroscope body probe 5 to move at the patient's lesion through the connecting block 24. Since the length of the arthroscope body probe 5 is the same as that of the push tube 23, the length of the patient's lesion can be measured by observing the moving length of the push tube 23 on one side of the tooth block 25. At the same time, by rotating the limiting rod 38, due to the limitation of the two threaded rods 35, when the threaded rods 35 rotate and move in the protective shell 6, the clamping plate 36 can be driven to move forward, so that the clamping plate 36 can clamp and fix the gear 34, thus avoiding the push tube 23 from moving again due to the accidental touch of the knob rod 33, which affects the measured length. After the measurement is completed, the clamping plate 36 needs to be reset. At this time, the tension spring 41 can pull the push tube 23 to reset it.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
