Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an auxiliary device for knee rheumatism needle knife endoscopy treatment. Background Technology

[0002] Among rheumatic diseases, gout is a relatively prominent symptom. This symptom is generally caused by high uric acid levels, which lead to the continuous deposition of urate crystals in the joints, forming gout crystals. In this symptom, gout crystals can damage the tissues around the joints, causing joint deformities. Some severe gout crystals can stubbornly grow in the joints, affecting the bones and even causing mobility problems. Therefore, minimally invasive needle knife endoscopic surgery is the preferred treatment for gout crystals in the knee joint.

[0003] At different bending angles, the internal structures of the knee joint cavity are exposed to varying degrees. The inability to bend the knee joint limits the doctor's observation and manipulation of various parts of the joint. Some lesions hidden in the joint space or behind the joint may be difficult to be fully exposed and treated, affecting the thoroughness of the surgery. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary device for knee rheumatism acupuncture and endoscopic treatment. A motor drives a steel cable to contract, which in turn pulls a connecting block. This connecting block then drives a slider, which in turn drives a left-hand beam. The left-hand beam then drives a right-hand beam. The combined action of the left and right beams causes the patient's leg to bend, thereby fully exposing diseased tissues that were previously hidden in the joint space or behind the joint, improving diagnostic accuracy and providing a guarantee for precise treatment.

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

[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] Reference Figure 1 - Figure 3This utility model provides an embodiment of an auxiliary device for knee rheumatoid arthritis acupuncture and knife endoscopy treatment, comprising: a support platform 1 serving as the main support body; limit rods 2 fixedly connected to both sides of the inner wall of the support platform 1; sliders 3 slidably connected to the outer walls of the limit rods 2; a left-turning beam 4 rotatably connected to the top of each slider 3; a right-turning beam 5 rotatably connected to the right end of each left-turning beam 4; the right end of the right-turning beam 5 rotatably connected to the top of the support platform 1; a connecting block 8 fixedly connected to the opposite end of each slider 3; a driving component provided at the left end of the connecting block 8; and a connecting platform 6 connected to both the left-turning beam 4 and the right-turning beam 5 via an adjusting component. The top of the device is provided with a restraint strap 7. The drive assembly includes a fixed plate 9 fixedly connected to the left side of the inner wall of the support platform 1. Support plates 10 are fixedly connected to both sides of the top of the fixed plate 9. A motor 11 is fixedly connected to the front end of the support plate 10. The drive end of the motor 11 passes through the support plate 10 and is fixedly connected to a collecting roller 12. A steel cable 13 is provided on the outer wall of the collecting roller 12. The right end of the steel cable 13 is fixedly connected to the left end of the connecting block 8. The outer wall of the collecting roller 12 is rotatably connected to the inner wall of the support plate 10. The outer wall of the connecting block 8 is slidably connected to the inner wall of the support platform 1. The outer wall of the slider 3 is slidably connected to the inner wall of the support platform 1.

[0025] Specifically, when it is necessary to bend the patient's leg, the motor 11 is started, and the drive end of the motor 11 begins to rotate. The tension generated by the rotation causes the steel cable 13 to gradually contract. Simultaneously, the contraction of the steel cable 13 exerts tension on the connecting block 8, causing it to move. This movement of the connecting block 8 then drives the slider 3 to slide along a specific track. As the slider 3 moves, the left-turning beam 4 connected to it moves accordingly. The left-turning beam 4 and the right-turning beam 5 are ingeniously interconnected through a mechanical structure. During the movement of the left-turning beam 4, the right-turning beam 5 also responds synchronously. The two work together to flex the patient's leg. By bending the knee, the lesions that were originally hidden in the joint space or behind the knee are fully exposed, which greatly improves the accuracy of the doctor's diagnosis and lays the foundation for subsequent precise treatment. When it is necessary to reset the patient's leg, the motor 11 is activated again. This time, the motor 11 performs the opposite action, releasing the steel cable 13. As the steel cable 13 is released, the tension acting on the left-turning beam 4 and the right-turning beam 5 disappears. The left-turning beam 4 and the right-turning beam 5 will slowly return to their initial positions under the action of the patient's own leg weight and muscle force, thus completing the reset of the left-turning beam 4 and the right-turning beam 5.

[0026] Reference Figure 1 , Figure 4 and Figure 5The adjustment assembly includes a slide table 14 slidably connected to the inner walls of the left turn beam 4 and the right turn beam 5. A fixing frame 15 is fixedly connected to the opposite end of the slide table 14. A pull rod 16 is slidably connected to the inner wall of the fixing frame 15. An insert plate 17 is fixedly connected to the opposite end of the pull rod 16. Insert blocks 18 are fixedly connected to both sides of the opposite end of the insert plate 17. A spring 19 is provided between the inner walls of the fixing frame 15 and the insert plate 17. The bottom end of the connecting platform 6 is fixedly connected to the top end of the slide table 14. One end of the spring 19 is connected to the insert plate 17, and the other end of the spring 19 is connected to the inner wall of the fixing frame 15. Multiple fixing holes 20 are provided on the inner walls of the left turn beam 4 and the right turn beam 5 corresponding to the insert blocks 18. The outer wall of the insert plate 17 is slidably connected to the inner wall of the fixing frame 15. The outer wall of the fixing frame 15 is slidably connected to the inner walls of the left turn beam 4 and the right turn beam 5.

[0027] Specifically, when the auxiliary device needs to be adjusted to suit the patient's leg length and other specific circumstances, first pull the lever 16. The lever 16 is connected to the insert plate 17. Pulling the lever 16 will cause the insert plate 17 to move synchronously. When the insert plate 17 moves, the insert block 18 fixed to it also moves, thereby causing the insert block 18 to disengage from the fixing hole 20. After the insert block 18 disengages from the fixing hole 20, the fixing frame 15 can be pulled. The fixing frame 15 is fixed to the slide table 14. Pulling the fixing frame 15 will cause the slide table 14 to move along the predetermined track. The slide table 14 is connected to the connecting platform 6. The movement of the slide table 14 naturally causes the connecting platform 6 to move. Once the connecting platform 6 moves to the desired position... After adapting the position to the patient's leg, place the patient's leg on the connecting platform 6 and fix the leg with the restraint strap 7. This operation allows the auxiliary device to be adjusted according to the patient's actual leg length, knee joint circumference, etc., ensuring that the device fits closely to the patient's body and provides stable support. When the position adjustment is completed and the connecting platform 6 is to be fixed, release the pull rod 16. At this time, the pre-compressed spring 19 begins to play its role. The spring 19 will quickly spring back the insert plate 17. When the insert plate 17 springs back, it drives the insert block 18 to move. Finally, the insert block 18 is precisely inserted into the fixing hole 20, thereby locking the connecting platform 6 and keeping the device in the position adapted to the patient.

[0028] Working principle: First, pull the lever 16 to move the insert plate 17. As the insert plate 17 moves, it causes the insert block 18 to disengage from the fixing hole 20. Then, pull the fixing frame 15 to move the slide table 14. As the slide table 14 moves, it moves the connecting platform 6. When the connecting platform 6 is in the appropriate position, place the leg on it. Then, use the restraint strap 7 to fix the patient's leg. This allows the auxiliary device to be adjusted according to the patient's specific situation, adapting to different leg lengths, knee joint circumferences, etc., ensuring the device fits snugly and stably against the patient's body. When the device is adjusted to the appropriate position, release the lever 16. When the lever 16 is released, the spring 19 will spring the insert plate 17. As the insert plate 17 springs, it causes the insert block 18 to move. When moving, the cable is inserted into the fixing hole 20 for fixation. When it is necessary to bend the patient's leg, the motor 11 is started, and its drive end rotates, causing the steel cable 13 to retract. When the steel cable 13 retracts, it pulls the connecting block 8 to move. When the connecting block 8 moves, it causes the slider 3 to move. When the slider 3 moves, it causes the left turning beam 4 to move. When the left turning beam 4 moves, it causes the right turning beam 5 to move. The cooperation of the left turning beam 4 and the right turning beam 5 causes the patient's leg to bend, thereby fully exposing the lesion tissue that was originally hidden in the joint space or behind, improving the accuracy of diagnosis and providing a guarantee for precise treatment. When it is necessary to reset, the motor 11 is started to release the steel cable 13. When the steel cable 13 is released, the left turning beam 4 and the right turning beam 5 will slowly reset along with the patient's leg.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
