Description

1 TARIFF TORQUE-LIMITED SLIP CLUTCH MANUAL MOBILIZATION APPARATUS Technological Field: This invention is relevant to manual therapy, joint mobilization / manipulation, and physiotherapy students. Torque-limited shear can be used in training and clinical skill standardization areas. It relates to the manual mobilization device with gripper. 10 State of the Art: In the current state of the technique, joints are used in manual therapy and rehabilitation applications. 15 applied directly by hand by the therapist for the purpose of mobilization and manipulation In addition to techniques, there are various manual methods that aid in the transmission of force or moment. Therapy devices and force feedback rehabilitation devices are used. In manual applications, the magnitude of the force and torque transmitted to the joint. largely depends on the manual force applied by the therapist, their experience, and perceptual abilities. It depends on the assessment. Therefore, the same mobilization technique may be used by different therapists. 20 addition during application by or in different applications by the same therapist Maintaining the transmitted mechanical load at the same level can become difficult, and the application Its repeatability may be limited. In the known technique, it is also possible to limit the transmission of force above a certain torque level. 25 Torque limiting hand tools and adjustable slip-clutch used for this purpose, another In other words, there are sliding clutch mechanisms. In these structures, the input and The mechanical connection between the output elements provides torque up to the specified torque level. It continues the transmission; when the determined threshold value is exceeded, the coupling elements... By sliding relative to each other, the torque transmitted to the output side is limited. This 30 This principle can be used particularly in torque instruments for surgical or industrial purposes. However, the structural and ergonomic features of such mechanisms are primarily... 2 tightening of connecting elements, controlled placement of surgical elements. or because it is intended for carrying out industrial mechanical processes, anatomical Manual joint mobilization requiring extensive and controlled contact on surfaces. It does not directly address the needs of the applications. Another approach used in rehabilitation is to measure force or torque values. Measurement via electronic sensors and visual presentation of the measured values ​​to the user. This is communicated audibly or numerically. These are types of force feedback systems. While enabling monitoring of the applied mechanical load, the sensor also provides electronic The measurement circuit, power source, display, or similar electronic components are needed. 10 They can hear it. This situation leads to increased complexity in the device structure, production and maintenance. the increasing needs and the therapist's measurement values ​​during the application This can lead to the need to monitor it. Also, it's not just the force or torque value that matters. Measuring and reporting to the user, and treating mechanical load when the threshold value is exceeded. It may not physically restrict the transfer to the region. 15 Another technical problem encountered with known manual therapy devices is the therapist's... used to transfer the movement generated by the body to the patient's anatomical surface. It is related to the structure of the contact elements. Small size or a specific contact Distal caps with this geometry allow the mobilization force to be applied to a large anatomical surface of 20. It may not provide sufficient contact area in applications where it needs to spread. Different anatomical regions with flat, curved, concave or different surfaces requiring local contact a contact element of a uniform or limited size due to having specific geometries This makes it difficult to adapt to different mobilization applications. As a result... The contact force is distributed appropriately to the desired surface and to different anatomical regions. 25 Limitations arise in terms of establishing a specific mobilization theme. It is possible to get out. The patent application with publication number JP5172846B2 describes "maximum tissue compression". "A surgical stapling instrument with a limiting mechanical mechanism" is described. 30 Patent application number GB2231293A for "Wrench with torque indicator" This is explained in the patent application with publication number US9216311B2, "Spinal treatment". 3 The device is described in the patent documents mentioned above for surgical applications. limiting mechanical force, controlling or displaying torque, and Various mechanical systems for spinal treatment are described. However, in known techniques, during manual joint mobilization and / or manipulation Adjusting the torque threshold value to be applied; if the determined threshold value is exceeded, 5 Mechanically limiting torque transmission through controlled slippage, preventing threshold overshoot. the mechanical movement is communicated to the user in an audible and / or tactile manner. with a wide range of interchangeable mobilization pads that can adapt to different anatomical surfaces the transfer functions are performed integrated within the same apparatus There are shortcomings in this regard. This situation affects manual therapy applications. controlled and repeatable application of force and torque dose, threshold instantaneous detection of overshoot and appropriate contact with different anatomical surfaces in a single step. This makes it difficult to achieve through mechanical means. In conclusion, in known techniques, rotation applied during manual therapy is 15 moment and compression torque at a selectable mechanical threshold level limiting this threshold so that it can be adjusted according to clinical practice, The threshold being exceeded can be detected instantly by the user, after the threshold is exceeded. mechanically limiting the transmission of excessive torque to the anatomical contact area and the ability to use a wide range of contact geometries suitable for different anatomical surfaces 20 There are shortcomings in terms of meeting their needs together. This shortcomings include the fact that the dose of manual mobilization remains dependent on the therapist's experience, variability between applications, risk of excessive mechanical load transfer insufficient control and in education and rehabilitation practices This can make it difficult to standardize the force / torque dosage. 25 Description of the invention: Thanks to this invention, the therapist can perform manual joint mobilization and manipulation. the torque generated by the rotational moment and the torque caused by compression were previously 30 It is limited by a mechanically defined threshold value.

It is allowed to slide in a controlled manner, independently of its adapter. Thus, the torque above the threshold value is transmitted through the adapter and mobilization pad 5 Its transfer to the application area is mechanically restricted. Thanks to the torque threshold adjustment ring included in the invention, the slip clutch is engaged. The threshold value can be changed. The preload spring on the friction discs This structure, based on adjusting the compression effect, ensures that the mobilization dose to be applied is 10. depending on the clinical scenario, application area, and required force / torque level This allows for selection. Thus, different applications can be used through a single device. Mechanical torque thresholds suitable for the conditions can be established, and the therapist can determine the specified dose. It is supported that it operates within this range. In addition to engaging the sliding clutch, separate click feedback is used. The element may alert the therapist audibly and / or if the specified torque threshold value is exceeded. It provides tangible feedback. This allows the therapist to simply observe the device's movements. not only does it take advantage of mechanical sliding motion, but it also instantaneously detects the threshold overshoot. It can perceive. The combined implementation of mechanical restraint and feedback, 20 especially during manual therapy training, the practitioner's specified force / torque dose to learn and to create more controlled mechanical load during application It contributes to the evaluation. The element located in the distal part of the invention directly functions as a small treatment head. 25 No, it's a pad connection adapter that allows different mobilization pads to be connected. Thanks to its configuration, the clinical contact surface can be changed. It is supplied. Flat, oval, concave, wedge or localized shapes that can be attached to the pad connection adapter are available. The wide range of interchangeable mobilization pads is suitable for different anatomical surface geometries. and allows the selection of contact surfaces suitable for different mobilization techniques. 30 It provides. Thanks to the pads with a large contact surface, the mobilization force is appropriate. In some cases, it can spread over a wider area and depend on the geometry of the anatomical surface. A harmonious connection can be established. The invention operates on the principle of mechanical torque limiting, thus eliminating the need for electronic force or 5 without the need for a torque sensor, electronic measuring circuit, display or battery. It is possible to control the mobilization dose. Adjustable torque threshold. mechanism, spring preloaded friction disc sliding clutch and click feedback The element's operation within the same mechanical structure; determining the threshold value, threshold Integrated detection of torque overload and limitation of excessive torque transmission. This structure also enables the protection of 10 products that may arise from electronic components. energy requirements and the complexity of use associated with the electronic measurement system It eliminates it. The invention mechanically modifies the mobilization dose administered by the therapist. by enabling control over a definable and repeatable threshold 15 reducing force / torque variability between the applications of different therapists It contributes, particularly in physiotherapy education and rehabilitation practices. a specific mechanical dose must be learned, repeated, and varied by the user. This feature makes it possible to implement it more consistently in applications.
