[0038] The following will further elaborate on this application with reference to the attached Figure 1-2 This application embodiment discloses a postoperative grip strength training device.

[0039] Refer to Figure 1 and Figure 2 As shown, a postoperative grip strength training device includes a grip strengthener 100 for muscle exercise by the patient's grip. The grip strengthener 100 includes an integrally provided arc-shaped upper part 110 and an arc-shaped lower part 120. The arc-shaped upper part 110 and the arc-shaped lower part 120 are combined with each other to form an oval shape for easy gripping by the patient. When the patient grips the device, by squeezing, the arc-shaped upper part 110 and the arc-shaped lower part 120 approach each other and then gradually separate, thereby cycling for muscle exercise. An elastic adjustment component 200 is provided between the arc-shaped upper part 110 and the arc-shaped lower part 120 for adjusting the elastic pressure component when the arc-shaped upper part 110 and the arc-shaped lower part 120 grip and squeeze, so that the required force for gripping can be adjusted according to the actual situation of the patient, thereby realizing personalized training. As the training progresses, the patient can increase the resistance gradually to increase the training difficulty and promote the enhancement of muscle strength. A touch sensor 270, a display 140, a speaker 150, and a controller 130 are also installed on the grip strengthener 100.

[0040] Refer to Figure 1 and Figure 2 As shown, the touch sensor 270 is fixedly installed between the arc-shaped upper part 110 and the arc-shaped lower part 120 for detecting corresponding signals generated when the patient grips and squeezes the grip strengthener 100. The display 140 is fixedly installed on the outer wall of the arc-shaped upper part 110 and is electrically connected to the touch sensor 270 for displaying the number of gripping actions and the duration. The speaker 150 is fixedly installed on the arc-shaped lower part 120 and is electrically connected to the display 140 for broadcasting the number and duration on the display 140. The controller 130 is installed on the arc-shaped upper part 110, is electrically connected to the touch sensor 270, the speaker 150, and the display 140, for receiving the signals sent by the touch sensor 270, controlling the display 140 to display corresponding information, and at the same time regulating the speaker 150 to broadcast the data displayed on the display 140.

[0041] The holding action of the patient is detected by the touch sensor 270, and the number of holds and the duration are fed back in real time through the controller 130 and the display 140, thereby helping the patient to perform grip strength training according to the preset standards, solving the problems in the prior art that the number of times and the time of the patient holding the ball are different, and ensuring the effectiveness and accuracy of the exercise. Through the speaker 150, the actions and rhythms of each exercise can be accurately broadcast, guiding the patient to exercise according to the standard procedure, improving the compliance of the patient, and ensuring the standardization and accuracy of the exercise. The specific voice prompt content includes: "Exercise starts", "Clench your fist for 1 second, 2 seconds, 3 seconds", "Open your fist for 1 second, 2 seconds, 3 seconds", and repeat clenching and opening the fist 50 times each (about 10 minutes in total), and finally broadcast "Exercise ends".

[0042] Referring Figure 1 and Figure 2 As shown, the elastic adjustment assembly 200 includes a support column 210, an adjustment column 230 and a positioning column 220. The support column 210 is fixedly connected to the center of the upper arc 110, and the support column 210 is arranged inside the upper arc 110, and the support column 210 extends away from it along the direction perpendicular to the inner wall of the upper arc 110. The positioning column 220 is fixedly connected to the inner wall of the lower arc 120, and the positioning column 220 and the support column 210 are on the same axis line, and the positioning column 220 extends in the direction towards the support column 210. The adjustment column 230 is threadedly connected to the positioning column 220, and the distance between the adjustment column 230 and the support column 210 can be changed by rotation. The touch sensor 270 is fixedly connected to the side wall of the support column 210. When the support column 210 abuts against the top end of the adjustment column 230, the touch sensor 270 contacts the side wall of the adjustment column 230, so that the touch sensor 270 collects this information and transmits it to the controller 130 while the extrusion is in place.

[0043] When using the gripper 100 for training, the patient can adjust the distance between the support column 210 and the adjustment column 230 by changing the position of the adjustment column 230 on the positioning column 220. This design enables the gripper 100 to adapt to the needs of different patients, thereby precisely controlling the force required during holding. As the training intensity increases or decreases, the position change of the adjustment column 230 will directly affect the magnitude of the force that the user needs to apply, thereby achieving the purpose of personalized training.

[0044] In addition, the touch sensor 270 can not only monitor the opening and closing state of the gripper 100, but also record the occurrence of each gripping action. When the user squeezes the gripper 100 so that the support column 210 abuts against the top of the adjustment column 230, the touch sensor 270 is activated to record a gripping action. By recording this data, the user can intuitively understand their training progress, such as the number of grips, duration, and average grip strength. This is crucial for monitoring training effectiveness and adjusting training plans, helping the user to continuously progress and achieve their personal fitness goals.

[0045] Referring to Figure 1 and Figure 2 As shown, the elastic adjustment assembly 200 further includes at least one support spring 260 disposed in the middle of the oval shape of the gripper 100. In this embodiment, preferably four support springs 260 are provided, and the four support springs 260 are symmetrically arranged in two groups on each side with the support column 210 as the center. By adopting four support springs 260, the present invention can provide a more uniform and stable gripping feedback. When the user squeezes the gripper 100, the four support springs 260 act together to ensure that the upper arc portion 110 and the lower arc portion 120 of the gripper 100 can smoothly approach and finally contact, thereby achieving a consistent gripping experience.

[0046] Wherein, the upper arc portion 110 and the lower arc portion 120 are respectively provided with receiving grooves 240 corresponding to their support springs 260, and the two ends of the support spring 260 are respectively embedded in the corresponding receiving grooves 240 and respectively abut against the inner sides of the upper arc portion 110 and the lower arc portion 120. Such a design ensures that the support spring 260 can stably play its role during use without deviation or movement, thereby ensuring the overall structural stability of the gripper 100. And the support spring 260 and the main body of the gripper 100 are detachably connected in this way, so that the user can increase or decrease the number of support springs 260 according to their needs, thereby changing the elastic pressure of the gripper 100.

[0047] The elastic adjustment assembly 200 further includes a hook 250 disposed on the upper arc portion 110. The hook 250 is installed in the receiving groove 240 of the upper arc portion 110 and is used to hang the support spring 260 to prevent the support spring 260. Prevent the support spring from falling off during use and causing harm to the patient.

[0048] The design of the elastic adjustment component 200 can easily adjust the resistance level of the gripper 100 according to the patient's exercise needs. For example, when the patient has a relatively small grip strength, and the way and frequency of using the gripper 100 are insufficient, the resistance can be reduced by using fewer support springs 260, which is convenient for the patient to adapt to and master the correct gripping technique. When the patient has a relatively large grip strength or after exercising for a certain period of time, the patient can increase the number of support springs 260 to increase the resistance and challenge a higher grip strength. Such a design greatly increases the functionality and flexibility of the gripper 100, meeting the diverse needs of different patients.

[0049] Referring Figure 1 and Figure 2 As shown, the upper arc 110 is provided with a groove 160 for accommodating the thumb or the carpometacarpal joint. When holding the gripper 100, the patient can place the thumb or the carpometacarpal joint in the groove 160, so as to hold the gripper 100 more firmly, improving the comfort and safety during training. This facilitates the patient to hold the gripper 100.

[0050] Among them, the lower arc 120 is provided with through holes 180 for accommodating the index finger, middle finger, ring finger and little finger. The penetrating direction of the through holes 180 is perpendicular to the extension direction of the support column 210. Such a design enables the patient's fingers to be naturally placed in the through holes 180 when holding the gripper 100, increasing both the stability of the grip and the comfort during gripping.

[0051] A extension strip 190 is fixedly connected to the side of the lower arc 120 away from the upper arc 110. The extension strip 190 extends in a direction away from the upper arc 110, thereby increasing the width of the gripper 100, thus enhancing the overall width of the gripper 100, facilitating the use by patients with larger palms and improving the applicability of the grip force. The extension strip 190 is also provided with accommodation holes 191 for accommodating the index finger, middle finger, ring finger and little finger respectively. The accommodation holes correspond to the through holes 180 on the lower arc 120 and are arranged along the direction away from the lower arc 120.

[0052] A bending groove 170 is provided at the connection between the upper arc 110 and the lower arc 120. The bending groove 170 is arc-shaped, and the opening direction of the bending groove 170 is along the direction perpendicular to the support column 210, that is, along the width direction of the gripper 100. In this way, when holding the gripper 100 and pressing the upper arc 110 and the lower arc 120, the gripper 100 will be bent at the bending groove 170, thus avoiding guiding the bending point and preventing the gripper 100 from cracking due to multiple bends during multiple uses.

[0053] The present utility model greatly improves the standardization and accuracy of postoperative grip strength training by introducing advanced sensor technology, an automated monitoring system, a voice prompt function, and personalized training support, helps reduce the incidence of complications, and at the same time alleviates the workload of medical staff.

[0054] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims described.
