Description

Technical Field

[0001] The invention relates to the technical field of hemiplegia correction equipment, and in particular to a limb corrector for hemiplegic patients after cerebral stroke. Background Art

[0002] Stroke, also known as apoplexy, is a disease that causes brain tissue damage due to sudden rupture of brain blood vessels or blockage of blood vessels that prevent blood from flowing into the brain. Hemiplegia refers to motor dysfunction of the limbs on one side due to cerebrovascular diseases such as stroke. Patients with hemiplegia usually wear limb correctors to assist in rehabilitation. Limb correctors, also called orthotics, can help control patients' abnormal movement patterns and spasms.

[0003] Upper limb orthosis is a commonly used auxiliary device for hemiplegic patients. It can fix joints or fractures, promote lesion or tissue healing, limit abnormal limb movement, and restore upper limb function. Antispastic wrist orthosis is a common upper limb orthosis. Patients will feel uncomfortable after wearing it and need a certain amount of time to adapt. In the actual rehabilitation process of hemiplegic patients after stroke, more emphasis is placed on wrist fixation and correction in the early stage. At this time, antispastic wrist orthosis is generally used, while in the later stage, more emphasis is placed on the recovery of hand function and the training of fine movements. At this time, antispastic grasping orthosis is generally worn. Different orthoses need to be replaced according to different rehabilitation stages. Replacing other types of orthoses requires patients to adapt again, which causes discomfort to patients again.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting the first corrective plate, the second corrective plate and the limit seat, the first corrective plate and the second corrective plate exist in two states in the limb corrector body. In the flattened state, they are parallel to the limb corrector body. After the patient wears it, the wrist can be fixed and corrected, which plays the role of an anti-spasmodic wrist orthosis. The first corrective plate and the second corrective plate in the bent state can fix the ends through the limit seat, which plays the effect of an anti-spasmodic grip orthosis, so that the limb corrector can be used in different rehabilitation stages of the patient without replacement, reducing the discomfort of the patient during the rehabilitation process.

[0016] By setting a limit assembly, a restraining belt and a finger cuff, the first correction plate and the second correction plate in the flattened state are limited and fixed, thereby ensuring the stability of the connection between the first correction plate and the second correction plate and the limb corrector body in the flattened state, and then ensuring the restraint and fixation effect of the restraining belt and the finger cuff on the first correction plate and the second correction plate on the patient's hand, thereby ensuring the fixation and correction effect of the patient's wrist during the patient's rehabilitation process.

[0017] By providing a fixing component and a first correction plate and a second correction plate, when the bent ends of the first correction plate and the second correction plate are inserted into the limit seats, they can be quickly and stably fixed by the fixing component. The fixing component is simple to operate, and is connected to the first correction plate and the second correction plate by a card slot. After the connection, it is stable and reliable, allowing the patient's hands to maintain a gripping state, and rehabilitation training of pinching posture can be performed by squeezing the bent first correction plate and the second correction plate, which has a better auxiliary effect on the patient's rehabilitation.

[0018] By setting the pull rod and the pull plate in the fixing component, the adjustment operation of the fixing component is simple and convenient, and it is easy for medical staff to use, so that it is convenient for medical staff to adjust the state of the limb orthosis. Secondly, the pull rod and the pull plate are stored in the cavity inside the limit seat after the adjustment is completed, which can effectively prevent the patient from accidentally touching the fixing component and causing it to be affected, thereby affecting the stability of the first correction plate and the second correction plate after bending and fixing, thereby enhancing the stability of the limb orthosis during use.

[0019] By setting the first correction plate and the inclined plate, after the first correction plate is bent and connected and fixed to the limit seat, the inclined plate can be pressed against the outside of the limit seat. When the patient pinches and grasps the bent first correction plate for rehabilitation training, the inclined plate can provide certain support for the first correction plate to enhance the training effect, and the inclined plate inclined toward the outside of the limit seat can provide a gripping position for the patient's other hand, so that the patient can bring both hands close together and stretch them, so that the limb corrector can assist the patient in performing multiple rehabilitation training, further improving the rehabilitation training effect of the limb corrector.

[0029] like Figures 1 to 11As shown, an embodiment of the present invention provides a limb corrector for hemiplegic patients after stroke, including a limb corrector body 1, in which a first corrective plate 2 and a second corrective plate 3 are fixedly connected, and a separation slit surrounding the outside of the first corrective plate 2 and the second corrective plate 3 is opened in the limb corrector body 1, and the separation slit between the limb corrector body 1 and the first corrective plate 2 and the second corrective plate 3 makes only one side of the first corrective plate 2 and the second corrective plate 3 form a connection relationship with the limb corrector body 1, while the other three sides are in an open structure, thereby making it possible to adjust the relative position between the first corrective plate 2 and the second corrective plate 3 and the limb corrector body 1, so that the shape of the limb corrector can be switched, and the first corrective plate 2 is provided with a first deformation zone 5 and a fourth deformation zone 12 on the outside, and the second corrective plate 3 is provided with a second deformation zone 10 and The opening of the third deformation zone 11, the first deformation zone 5 and the fourth deformation zone 12 as well as the second deformation zone 10 and the third deformation zone 11 makes the thickness of the first correction plate 2 and the second correction plate 3 at the corresponding positions thinner and weaker, so that the first correction plate 2 and the second correction plate 3 can be deformed in the first deformation zone 5 and the fourth deformation zone 12 as well as the second deformation zone 10 and the third deformation zone 11 respectively after being acted upon by external force, so that the first correction plate 2 and the second correction plate 3 are easy to bend, and the shape of the entire limb corrector is changed to adapt to the patient's use needs at different rehabilitation stages. The first correction plate 2 and the second correction plate 3 are both provided with a card slot 9, and the bottom of the limb corrector body 1 is fixedly connected to the limiting seat 14; the limiting component is used to fix the relative position between the first correction plate 2 and the second correction plate 3 and the limb corrector body 1 after they are unfolded.

[0030] The limiting component is connected to the limb corrector body 1; the fixing component is used to fix the relative position between the first correction plate 2 and the second correction plate 3 and the limiting seat 14 after bending. The fixing component is connected to the limiting seat 14. The limiting component can limit and fix the first correction plate 2 and the second correction plate 3 in the flattened state to ensure the stability of the connection between the first correction plate 2 and the second correction plate 3 and the limb corrector body 1 in the flattened state. It is used in the early stage of patient rehabilitation, mainly for wrist fixation and correction. The limiting seat 14 is used to assemble the fixing component to provide a stable working environment and installation position for the fixing component. The fixing component is used to form a connection and fixing relationship between the ends of the first correction plate 2 and the second correction plate 3 after bending and the limiting seat 14, to ensure the structural stability of the first correction plate 2 and the second correction plate 3 in the bent state. It is used in the middle and late stages of patient rehabilitation, mainly for cooperating with patients in various rehabilitation training movements.

[0031] In this embodiment, if Figure 1 to Figure 2As shown, the separation seam is U-shaped, the first deformation zone 5 is arranged at the connection between the first correction plate 2 and the limb corrector body 1, and the second deformation zone 10 is arranged at the connection between the second correction plate 3 and the limb corrector body 1. The U-shaped structure of the separation seam can make the first correction plate 2 and the second correction plate 3 be connected to the limb corrector body 1 by one edge, while the other edges are affected by the separation seam and are in an open structure, providing basic conditions for the switching of the first correction plate 2 and the second correction plate 3 between the flattening and bending states. The first correction plate 2 and the second correction plate 3 are both fixedly connected with finger sleeves 6, and the first correction plate 2 and the second correction plate 3 are both fixedly connected with support pads 7 corresponding to the positions of the finger sleeves 6. The limb corrector body 1 is fixedly connected with evenly distributed restraint belts 4. There are four finger sleeves 6 on the first correction plate 2, corresponding to the four fingers of the patient except the thumb, and the position corresponding to the little finger is closer to the first deformation zone. The finger sleeve 6 on the first correction plate 2 and the second correction plate 3 can cooperate with the restraint belt 4 on the limb corrector body 1 to restrain and fix the patient's fingers and palm as well as the arm around the wrist, which can have a good fixation and correction effect on the patient's wrist.

[0032] In this embodiment, if Figures 1 to 5As shown, the limiting assembly includes a fixing plate 13 fixedly connected to the outside of the limb corrector body 1, and there are two fixing plates 13. The positions of the two fixing plates 13 correspond to the positions of the slots 9 on the first correction plate 2 and the second correction plate 3, respectively. One end of the fixing plate 13 is fixedly connected to the outside of the limb corrector body 1, and the other end of the fixing plate 13 is provided with a first bent end 20. A block 21 adapted to the shape of the slot 9 is fixedly connected to the fixing plate 13, and a first weakened groove 19 is provided on the fixing plate 13. When the first correction plate 2 and the second correction plate 3 are both in a flattened state, the block 21 on the fixing plate 13 can be snapped into the slots 9 at the ends of the first correction plate 2 and the second correction plate 3, so that the first correction plate 2 and the second correction plate 3 are supported and limited by the fixing plate 13, so as to maintain the limb corrector body 1 and the first correction plate 2 and the second The parallel state between the correction plates 3 ensures the fixation and correction effect of the first correction plate 2 and the second correction plate 3 on the patient's wrist in cooperation with the restraint belt 4 and the finger sleeve 6. The first weakened groove 19 opened on the fixing plate 13 makes the thickness of the fixing plate 13 at the first weakened groove 19 thinner and weaker, and is more likely to deform after being subjected to external force. At the same time, the setting of the first bent end 20 reserves a certain gap between the fixing plate 13 and the bottom of the limb corrector body 1. After the medical staff puts their fingers into the gap between the first bent end 20 and the limb corrector body 1, they can move the fixing plate 13 to produce a bending deformation at the first weakened groove 19, thereby releasing the supporting and fixing effect of the fixing plate 13 on the first correction plate 2 or the second correction plate 3, allowing the first correction plate 2 and the second correction plate 3 to be deflected and deformed, which facilitates the first correction plate 2 and the second correction plate 3 to change their shapes.

[0033] In this embodiment, if Figures 7 and 8As shown, the fixing assembly includes a movable plate 24 sleeved in the limiting seat 14, and a fixing column 25 is fixedly connected to the top of the movable plate 24, and the fixing column 25 is adapted to the size of the slot 9. An inclined plate 8 located between the support pad 7 and the slot 9 is fixedly connected to the first correction plate 2. After the first correction plate 2 is bent and connected and fixed to the limiting seat 14, the inclined plate 8 can be pressed against the outside of the limiting seat 14. During the patient's grasping of the bent first correction plate 2 for rehabilitation training, the inclined plate 8 can provide certain support for the first correction plate 2 to enhance the training effect. The inclined plate 8 inclined toward the outside of the limiting seat 14 can also provide a gripping position for the patient's other hand, so that the patient can bring both hands close and stretch them to perform multiple rehabilitation training, further improving the rehabilitation training effect of the limb corrector. An L-shaped inclined surface opening 16 is provided on the outer side of the limiting seat 14, and a first connecting groove 17 and a second connecting groove 18 are provided in the limiting seat 14. The openings of the inclined surface opening 16, the first connecting groove 17 and the second connecting groove 18 are The position corresponds to the insertion position of the ends of the first correcting plate 2 and the second correcting plate 3 into the limiting seat 14. The opening of the inclined surface 16 forms an inclined surface at the entrance of the first connecting groove 17 and the second connecting groove 18, so that the entrance area of ​​the first connecting groove 17 and the second connecting groove 18 is larger, which is convenient for inserting the ends of the first correcting plate 2 and the second correcting plate 3. The first connecting groove 17 is adapted to the size of the first correcting plate 2, and the second connecting groove 18 is adapted to the size of the second correcting plate 3. There are two groups of fixing columns 25, and the positions of the two groups of fixing columns 25 correspond to the positions of the first connecting groove 17 and the second connecting groove 18 respectively. When the first correcting plate 2 and the second correcting plate 3 are bent, after the ends are inserted into the first connecting groove 17 and the second connecting groove 18, the fixing columns 25 on the movable plate 24 can pass through the card slots 9 on the first correcting plate 2 and the second correcting plate 3, thereby forming a connection relationship between the first correcting plate 2 and the second correcting plate 3 and the limiting seat 14, and maintaining the bending state of the first correcting plate 2 and the second correcting plate 3.

[0034] In this embodiment, if Figures 7 to 11As shown, a cavity for accommodating the movable plate 24 is opened in the limit seat 14, and the cavity in the limit seat 14 provides a space for accommodating the movable plate 24. At the same time, the movable plate 24 can move in the cavity and drive the fixed column 25 to move, thereby adjusting the relative position between the fixed column 25 and the slot 9, and controlling the connection and fixing state between the first correction plate 2 and the second correction plate 3 and the limit seat 14. The bottom of the movable plate 24 is fixedly connected with an elastic plate 29, and the connection between the elastic plate 29 and the movable plate 24 is S-shaped, and the elastic plate A second weakened groove 30 is provided at the connection between the first correction plate 2 and the movable plate 24. The second weakened groove 30 makes the structure of the elastic plate 29 at the second weakened groove 30 thinner, and can be deformed more easily after being subjected to external force. The elastic plate 29 is used to support the movable plate 24, maintain the position of the movable plate 24 in the internal cavity of the limit seat 14, and indirectly maintain the position of the fixed column 25 on the movable plate 24. After the ends of the first correction plate 2 and the second correction plate 3 are respectively inserted into the first connection groove 17 and the second connection groove 18, the elastic plate 29 can The ends of the first correction plate 2 and the second correction plate 3 can be fixed by the fixing column 25. During the sliding process of the movable plate 24, the S-shaped area on the elastic plate 29 will be bent and deformed, and the elastic plate 29 will accumulate elastic potential energy. After the external force on the movable plate 24 is removed, the elastic plate 29 can drive the movable plate 24 to reset by its own elastic force. The bottom of the movable plate 24 is fixedly connected with a pull rod 26, and the end of the pull rod 26 is fixedly connected with a pull plate 15. The two ends of the pull plate 15 are provided with a second bent end 27. The length value is smaller than the depth value of the cavity in the limit seat 14. By pulling the pull plate 15, the movable plate 24 can be driven to slide in the cavity through the transmission of the pull rod 26, thereby changing the positions of the movable plate 24 and the fixed column 25. The relationship between the length value of the pull rod 26 and the depth value of the cavity in the limit seat 14 enables the pull rod 26 and the pull plate 15 to be stored in the cavity inside the limit seat 14 after adjustment, which can effectively prevent the patient from accidentally touching the fixed assembly and causing it to be affected, thereby affecting the stability of the first correction plate 2 and the second correction plate 3 after bending and fixing.

[0035] The second bent ends 27 at both ends of the pull plate 15 are inclined toward the outside of the limiting seat 14 to form a curling edge, so that the medical staff who pulls the pull plate 15 can directly pull the pull plate 15 to pull the movable plate 24, or can buckle the second bent end 27 to pull the movable plate 24. The operation method is more diverse and easy for medical staff to use. The bottom of the elastic plate 29 is provided with a second through circular opening 31, and the bottom of the limiting seat 14 is provided with a first through circular opening 22. The positions of the first through circular opening 22 and the second through circular opening 31 correspond to each other, and the openings of the first through circular opening 22 and the second through circular opening 31 are It is designed that the bottom of the limit seat 14 is connected to the outside world, so that medical staff can insert their fingers into the cavity of the limit seat 14 to adjust the fixed component. The limit seat 14 is fixedly connected with evenly distributed guide rods 23, and the movable plate 24 is provided with a guide opening 28 that is adapted to the shape of the guide rod 23. The guide rod 23 and the guide opening 28 are sleeved and connected. The movable plate 24 is guided by the guide rod 23 and the guide opening 28 during the sliding process in the cavity, so as to maintain the activity track of the movable plate 24 and avoid dislocation during the activity of the movable plate 24.

[0036] The working principle of the technical solution provided by the present invention is as follows: When in use, in the initial state, the first correction plate 2 and the second correction plate 3 are both kept in the unfolded state, the fixing plate 13 supports and limits the first correction plate 2 and the second correction plate 3, the patient's hand and wrist are placed in the limb corrector body 1 for wearing, the thumb is passed through the finger sleeve 6 on the second correction plate 3, and the other four fingers are passed through the finger sleeve 6 on the first correction plate 2, and then the restraint belt 4 is untied and wrapped around the patient's palm and the outside of the arm around the wrist to fix and correct the patient's wrist.

[0037] As the patient recovers, when the shape of the first correction plate 2 and the second correction plate 3 needs to be replaced, the fixing plate 13 is pushed from the first bent end 20, so that the fixing plate 13 is bent and deformed at the first weakened groove 19, driving the block 21 to withdraw from the slot 9 on the first correction plate 2 and the second correction plate 3, thereby releasing the support and fixing state of the first correction plate 2 and the second correction plate 3.

[0038] The first correction plate 2 and the second correction plate 3 are moved so that the first correction plate 2 and the second correction plate 3 are bent and deformed at the first deformation zone 5 and the fourth deformation zone 12 and the second deformation zone 10 and the third deformation zone 11 respectively, and the pull plate 15 is moved so that the pull plate 15 drives the movable plate 24 to slide through the pull rod 26, and then the fixed column 25 on the movable plate 24 is withdrawn from the first connecting groove 17 and the second connecting groove 18, and the ends of the first correction plate 2 and the second correction plate 3 are inserted into the first connecting groove 17 and the second connecting groove 18. After insertion, the pull plate 15 is released, and the movable plate 24 is reset under the elastic force of the elastic plate 29, and the movable plate 24 drives the fixed column 25 to penetrate the slot 9 at the ends of the first correction plate 2 and the second correction plate 3, and the ends of the first correction plate 2 and the second correction plate 3 are connected and fixed to the limit seat 14.

[0039] After the first correction plate 2 and the second correction plate 3 are bent and connected to the limiting seat 14, the first correction plate 2 and the second correction plate 3 can be pinched for rehabilitation training after being worn, and the inclined plate 8 is pressed against the outer side of the limiting seat 14 to support the first correction plate 2, thereby increasing the resistance when pinching the first correction plate 2. At the same time, the hand that is not wearing the limb corrector can hold the inclined plate 8, and then both hands can perform stretching training at the same time to complete the entire process of using the limb corrector for hemiplegic patients after stroke.
