Description

TECHNICAL FIELD

[0001] The present application relates to the field of spinal orthopedic technology, in particular to a spinal orthosis. BACKGROUND

[0002] Spinal orthosis is mainly divided into flexible spinal orthosis and rigid spinal orthosis. The flexible spinal orthosis is a correction appliance for treating scoliosis or other spinal deformities. Compared with the traditional rigid orthosis, the flexible spinal orthosis has more flexible characteristics and can better adapt to the activity needs of the body. Chinese patent (publication number: CN117860456B) discloses a flexible spinal orthosis, which relates to the technical field of medical rehabilitation auxiliary appliances. The flexible spinal orthosis comprises a correction mechanism, a traction mechanism, a connecting support mechanism, and a locking mechanism. The locking mechanism is arranged on the traction mechanism, and the traction mechanism is arranged on the correction mechanism. The correction mechanism comprises an upper correction force shoulder strap, a middle correction force connecting plate, a lower correction force connecting plate, an upper correction force belt, a middle correction force belt, a lower correction force belt, and a fixed waist belt. The fixed waist belt and the middle correction force connecting plate are connected with the connecting support mechanism. The above-mentioned comparative document mainly relies on the upper correction force shoulder strap and the lower correction force connecting plate to fix and implement the orthosis. However, this technology has significant shortcomings. First, the force is concentrated on the upper correction force shoulder strap and the lower correction force connecting plate, which causes excessive local pressure and easily causes discomfort and injury on one side of the patient's body. Second, when using this method, the patient may feel uncomfortable compression when wearing the orthosis for a long time, which not only affects the comfort of the patient but also may further cause physical discomfort. In view of the above technical problems, the present application proposes a spinal orthosis to solve the above technical problems. SUMMARY

[0007] As a preferred technical scheme of the present application, the corrugated sleeve is made of medical-grade elastic silica gel material, and the outer wall is provided with a corrugated structure which can produce regular compression deformation when under pressure and provide a flow buffer space for the gas in the cavity.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 As shown, a spinal orthosis includes an orthosis body, an upper corrective force-applying shoulder strap 1, and a lower corrective force-applying connecting plate 101. The upper correction force shoulder strap 1 is connected with the lower correction force connecting plate 101 through a detachable sub-mother buckle, and the surface of the connecting belt 2 is slidably connected with six sliding blocks 201. The sliding blocks 201 are slidably connected with sliding plates 202 on one side, and the sliding plates 202 are fixedly connected with pull belts 203 for driving sliding on the side away from the sliding blocks 201. The inner cavity of each sliding block 201 is fixedly connected with a plastic plate 204, and the inner cavity of the sliding plate 202 is fixedly connected with four fixed needles 205. One end of the four fixed needles 205 penetrates through the connecting belt 2 and extends into the inner cavity of the corresponding plastic plate 204. The side away from the sliding plate 202 of the sliding block 201 is connected with a contact block 207 through a corrugated sleeve 206. The surface of the contact block 207 is provided with a circular groove matched with the curvature of the human body, and a first reset spring 208 is arranged between the sliding plate 202 and the sliding block 201. The detachable sub-mother buckle connection is convenient for quick wearing and disassembling, and meets the adjustment needs of different body types or use scenes. The combination design of the sliding block 201 and the sliding plate 202 allows the user to manually adjust the position of the sliding block 201 on the connecting belt 2 through the pull belt 203, and adjust the position of the contact block 207. The layout of the six sliding blocks 201 forms multi-point support, avoids excessive pressure on a single part, and enhances the stability of the overall structure. The fixed needle 205 penetrates through the connecting belt 2 and is inserted into the plastic plate 204, forming a mechanical locking structure to ensure the fixed position of the sliding block 201 after adjustment, preventing displacement caused by movement during use. The first reset spring 208 provides elastic buffering, and the tension of the first reset spring 208 assists the reset of the sliding plate 202 when adjusting the pull belt 203, avoiding hard collision between the fixed needle 205 and the plastic plate 204, and improving the operation smoothness. The circular groove is matched with the curvature of the human body side to ensure that the contact block 207 is closely attached to the human body side, reduces local compression, and improves the wearing comfort. The corrugated sleeve 206 allows the contact block 207 to swing slightly with the movement of the human body, dynamically adapts to the spine activity (such as breathing and turning), avoids discomfort or skin damage caused by rigid contact, and improves the operation smoothness. The corrugated structure of the corrugated sleeve 206 produces regular compression deformation when subjected to pressure, absorbs part of the pressure through elastic deformation, and provides a buffer space for gas flow in the inner cavity (see the description below), further optimizing the pressure distribution. Two gas inlet and outlet pipelines 3 are arranged on one side of the sliding block 201, and the inner cavities of the two gas inlet and outlet pipelines 3 are provided with four thin sheets 301 arranged in a ring shape. The thin sheets 301 are made of elastic plastic material. As a one-way valve structure, when the corrugated sleeve 206 is compressed (such as when the human body squeezes the contact block 207), the gas in the inner cavity compresses the thin plate 301 through the inlet and outlet pipes 3, causing it to deform and exhaust through the inlet and outlet pipes 3, releasing the internal pressure and avoiding excessive compression; when the pressure is released, the corrugated sleeve 206 elastically recovers, the thin plate 301 deforms in the opposite direction, and air is drawn in through the inlet and outlet pipes 3 to return to its original shape, realizing a dynamic adaptive process of "pressure-induced exhaust and fitting, pressure-release and air-intake reset". When the corrugated sleeve 206 is compressed, the gas inside the corrugated sleeve 206 compresses the sheet 301 through the air inlet and outlet pipe 3, causing it to deform and releasing the seal on the air inlet and outlet pipe 3 to discharge air. When the corrugated sleeve 206 is not compressed, it returns to its original shape by its own elasticity. At the same time, the sheet 301 deforms in the opposite direction to open the air inlet channel, allowing air to enter the inner cavity of the corrugated sleeve 206 through the air inlet and outlet pipe 3. The corrugated sleeve 206 is made of medical-grade elastic silicone material. Its outer wall has a corrugated structure, which can produce regular compression deformation when under pressure, while providing a buffer space for the flow of gas in the inner cavity. Medical-grade silicone meets medical safety standards, is non-toxic and hypoallergenic, and is suitable for direct skin contact; its high elasticity and aging resistance ensure that it will not easily deform or crack with long-term use; The corrugated structure expands the internal cavity volume, increases the gas storage space, and at the same time guides the airflow directionally through the inlet and outlet pipes 3 during compression, improving the response speed and stability of pressure regulation. Four thin plates 301 are evenly distributed in a 90° ring around the central axis of the air inlet / outlet pipe 3. The thickness of each thin plate 301 is 0.3 to 0.5 mm, and its edge near the corrugated sleeve 206 is fixedly connected to the inner wall of the air inlet / outlet pipe 3. Four thin sheets 301 are evenly distributed in a 90° ring to ensure uniform airflow and avoid sealing failure caused by force in one direction; the thickness of the 0.3 to 0.5 mm thin sheets 301 balances elasticity and sealing performance, allowing them to deform quickly under slight pressure and close tightly when there is no pressure to prevent air leakage. The uniform ring distribution allows the sheet 301 to deform synchronously under pressure, avoiding local air leakage or jamming caused by uneven force. The edge fixing design ensures that the sheet 301 only opens to one side (towards the outside), forming a one-way valve function to prevent gas backflow. The thickness of the 301 sheet determines the pressure threshold required for its elastic deformation (the thinner the sheet, the lower the opening pressure). The range of 0.3 to 0.5 mm can be flexibly adjusted through material selection to adapt to different correction force requirements (such as differences between children and adults). The two ends of the corrugated sleeve 206 are fixedly connected to the sliding block 201 and the contact block 207 respectively through a hot vulcanization process to form an airtight connection structure. The heat vulcanization process ensures that there is no glue residue or gap between the corrugated sleeve 206 and the sliding block 201 and the contact block 207, avoiding air leakage or structure falling caused by bonding failure, and can be suitable for frequent use and cleaning scenes; The contact block 207 is made of memory cotton material, and the curvature parameters of the circular arc groove match the lateral curvature of the human thoracic spine segment. The surface of the circular arc groove is provided with a covering layer. The memory cotton material has a slow rebound characteristic and can automatically shape along the human body curve to provide uniform support continuously. The covering layer is a soft skin-friendly material, and the covering layer and the contact block 207 are bonded by food-grade glue. The skin-friendly covering layer (such as cotton or silicone material) reduces direct friction with the skin, and the food-grade glue avoids chemical irritation, which is suitable for patients with sensitive skin and reduces the risk of contact dermatitis. The connecting belt 2 is an elastic fabric belt, and a scale line is arranged on the surface of the connecting belt 2 along the length direction, which is used for identifying the sliding position of the sliding block 201. The scale line helps medical staff or users to intuitively read the position of the sliding block 201. The elastic fabric belt can absorb part of the tensile force generated by body movement to avoid excessive rigid force. The pull belt 203 is made of polyester fiber fabric belt, the surface of the pull belt 203 is provided with anti-skid convex patterns, and the inside of the pull belt 203 is embedded with a fiber reinforced layer. The anti-skid convex patterns improve the friction force of fingers, so that the pull belt 203 can be easily adjusted even if the hands are wet, which is especially suitable for patients to operate by themselves; the fiber reinforced layer enhances the tensile strength to prevent breakage after long-term use. The polyester fiber material is light and wear-resistant, which reduces the overall weight of the orthosis, and the soft texture avoids hurting the human body surface. The sliding block 201, the sliding plate 202 and the fixing needle 205 are all made of hard material, wherein the sliding block 201 and the sliding plate 202 are made of ABS engineering plastic material, and the fixing needle 205 is made of stainless steel material. ABS engineering plastic has rigidity and toughness, which ensures that the sliding block 201 and the sliding plate 202 are not deformed during frequent adjustment; the stainless steel fixing needle is corrosion-resistant and wear-resistant, and is not easy to be passivated or broken after long-term plugging, which ensures the reliability of the locking mechanism.

[0021] Wearing positioning: first, the orthosis body is attached to the specific part of the patient's body to complete the basic wearing, and ensure that the upper correction force shoulder belt 1 and the lower correction force connecting plate 101 form a stable upper and lower support frame; Elastic connection construction: the two ends of the connecting belt 2 are fixed to the shoulder belt and the connecting plate through the mother and daughter buckles, so that the six contact blocks 207 distributed on the connecting belt 2 are evenly attached to the surface of the patient's body, and each contact block 207 forms a multi-point support array through a flexible structure, effectively disperses the contact pressure, and avoids that a single part bears overload; Pressure response: when the contact block 207 is pressed by the body surface pressure, the internal corrugated sleeve 206 deforms elastically, the gas in the cavity pushes the thin sheet 301 to deform elastically, and the sealing state of the gas inlet and outlet pipeline 3 is released, and the gas is quickly discharged. During this process, the contact block 207 synchronously retracts to ensure that it is always attached to the body surface, avoiding discomfort caused by rigid extrusion; When the external pressure disappears, the corrugated sleeve 206 restores to its original state by its own elasticity, forming a local negative pressure environment. At this time, the thin sheet 301 deforms reversely to open the air inlet channel, and the external air fills the inner cavity of the corrugated sleeve 206 through the gas inlet and outlet pipeline 3. The contact block 207 synchronously extends and is supported by the gas to maintain dynamic attachment to the body surface, realizing comfortable contact in the whole motion cycle; Unlocking and adjusting: hold the pull belt 203 and apply a pulling force to drive the sliding plate 202 to move outwardly against the elastic force of the first return spring 208, so that the fixed needle 205 is disengaged from the inner cavity of the plastic plate 204 and the puncture of the connecting belt 2 is released. At this time, the sliding block 201 is unlocked and can freely slide axially along the connecting belt 2, realizing the position fine adjustment of the contact block 207. Locking and fixing: after the pull belt 203 is released, the first return spring 208 releases the stored energy to push the sliding plate 202 to reset, and the fixed needle 205 successively pierces the connecting belt 2 through the pre-set hole positions and is embedded into the positioning groove of the plastic plate 204. The plastic plate 204 serves as an isolation structure to ensure that the end of the fixed needle 205 does not contact the patient's body surface, forming a "puncture locking-physical isolation" double protection mechanism, effectively resisting the displacement load generated during the movement, and ensuring the stability and reliability of the position after adjustment.
