Description

Technical Field

[0001] The invention relates to the technical field of training instruments, in particular to a functional training instrument after forearm skin grafting. Background Art

[0002] Some surgeries for oral cancer patients often require skin flaps from the forearm. Since the skin flaps are removed together with the arteries and veins, the hand will swell significantly after the operation, and the thumb, ring finger, and middle finger will be numb for a long time. At this time, finger exercise equipment will be needed to perform functional exercises and establish microcirculation.

[0003] The authorized patent number CN218686105U discloses a finger exerciser. The device mainly uses a plurality of finger sleeves to be close to each other due to the traction of elastic rubber bands before the patient's fingers exert force. When the patient's fingers exert force, the plurality of finger sleeves are separated in a radial shape. At this time, the elastic rubber bands are stretched, and the patient's fingers exert force intermittently and regularly, so that the fingers can achieve a better exercise effect. The plurality of finger sleeves are moved upward from the inside of the placement tube, and the position of the movable mechanism on the finger sleeve is adjusted up and down. Compared with the prior art, the position of the finger force point can be changed, so that all parts of the fingers can be fully exercised. However, when the device is actually used, the following defects still exist:

[0004] The above patent mainly separates a plurality of finger sleeves in a radial shape to prompt the patient's fingers to exert force intermittently and regularly so that the fingers can achieve a better exercise effect. However, the existing exercise device structure usually simply provides a finger pressing activity structure to assist finger exercise. The actual exercise is relatively blind. The aimless exercise is likely to increase the patient's psychological pressure and affect the rehabilitation effect of the exercise. In addition, the pressing force of the exercised fingers is not easy to adjust and is difficult to adjust according to the needs of different patients. At the same time, it is not easy to stably support the palm during finger exercise. At the same time, the fingers are prone to tension and sweating, which increases the patient's discomfort.

[0037] Embodiment 1, as Figure 1-4 As shown, when performing finger rehabilitation exercises, first start the electric push rod 401 to drive the support seat 404 to lift up as a whole, so that the palm part is placed above the support seat 404, thereby supporting the palm so that each finger contacts the pressing rod 3 for pressing exercises, so as to adjust the specified height to assist in supporting the fingers, and at the same time, start the driver 402 to drive the first bevel gear 406 to rotate, so that the first bevel gear 406 drives five groups of mutually meshing second bevel gears 407 to force the fan blades 405 to rotate and start, so as to form wind force to blow and dissipate heat to the five groups of finger parts, thereby relieving the psychological pressure of finger exercise, suppressing finger sweating, and improving the comfort of the structure. At the same time as the first bevel gear 406 rotates, it drives the turntable 408 to rotate, so that the turntable 408 drives multiple groups of massage balls 409 to roll under the massage pad. At this time, the palm part contacting the massage pad can be subjected to the rolling force generated by the rolling of the massage balls 409, thereby forming a massage structure to assist in massaging the palm and improve the patient's comfort and exercise effect.

[0038] Embodiment 2, as Figure 1-4As shown, pressing training can be performed by controlling seven musical notation notes, so that the fingers can be trained while playing the music, and the strength can be adjusted and resistance training can be performed. By setting the voice control module and connecting the app terminal for remote control, voice time is provided to provide the patient with exercise time, and a specified time can be set on the terminal to allow the post-operative fingers to undergo more comprehensive functional exercises based on the calculated intensity.

[0039] Working principle: This forearm skin grafting postoperative functional training instrument;

[0040] When exercising the fingers after forearm skin grafting, five notes can be pressed on the five groups of note keys 13, and then the index finger, thumb and middle finger are pressed synchronously as one note, and the ring finger and little finger are pressed synchronously as one note, for a total of seven notes. During the exercise, five fingers are placed on the top surface of the pressing rod 3, and then the pressing rod 3 is pressed to drive the spring 14 to elastically stretch in the sleeve 2, so that the pressing rod 3 is pressed in contact with the note key 13 under the action of pressure. When the note key 13 is pressed, the corresponding note can be emitted through the control of the PCB board 12 and the sound device 5, and the indicator light 6 at the corresponding position lights up, so as to assist the patient to play more clearly, with the goal of practicing a perfect song, so that the patient can perform purposeful exercise rehabilitation, and greatly reduce the patient's psychological pressure, reduce the vascular contraction caused by tension and the complications caused by emotions;

[0041] The servo motor 8 can be started to drive the first gear 7 to rotate, so that the first gear 7 and the second gear 9 are meshed with each other, and the screw rod 10 can be rotated. At this time, the lifting mounting platform 11 can be driven to move up and down under the guidance of the two groups of guide columns 16 and the guide holes 15 under the rotation of the screw rod 10, so as to adjust the distance between the five groups of note keys 13 and the pressing rod 3, so as to adjust the pressing force of the pressing rod 3, so as to adjust it according to different patients, improve the flexibility of structural adjustment, and increase the rehabilitation effect of finger exercise.

[0042] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
