Description

Technical Field

[0001] This invention relates to the field of intraoperative lateral decubitus position nursing technology, and in particular to an auxiliary restraint device for intraoperative lateral decubitus position. Background Technology

[0002] The lateral decubitus position is one of the key positions in surgical procedures, widely used in fields such as spinal surgery, thoracic surgery, urology, and orthopedics. Maintaining a stable, precise, and safe lateral decubitus position is crucial for ensuring the smooth progress of surgery and preventing complications.

[0003] Currently, the establishment and maintenance of the lateral decubitus position in clinical practice mainly relies on the following methods and devices, but they all have significant limitations: First, it lacks stability and security: Traditional padding fixation: Soft pads, gel pads, or rolls are commonly used to support the patient's back. However, during surgery, the patient may tilt forward or backward due to operating table movement, surgeon's manipulation, or the patient's own weight after muscle relaxation, causing a change in position. This not only affects the exposure of the surgical field but can also lead to disastrous consequences in delicate surgeries such as those involving the spine.

[0004] Medical tape fixation: Wide tape is used to attach the patient's torso or pelvis to the operating table. Its fixation strength is limited, and it is prone to loosening due to sweating during prolonged surgery. Furthermore, removing the tape may damage the skin, especially in elderly patients or those with sensitive skin.

[0005] Second, it has limited functionality and is inconvenient to adjust: Most existing fixation devices or pads are single-function, and once placed, fine-tuning (such as adjusting height or angle) is extremely difficult. If a slight adjustment to the operating table angle is needed during surgery to improve exposure, the entire fixation system may need to be disassembled and reinstalled, interrupting the surgical procedure.

[0006] Third, the balance between ergonomics and surgical exposure: Traditional methods struggle to achieve a perfect balance between "stabilizing and immobilizing the patient" and "providing the surgeon with optimal operating space and exposure."

[0007] Inaccurate neuroprotection: Protection of key areas such as the armpit is still a rough design, lacking precise anatomical positioning and personalized adjustment functions.

[0008] Insufficient ergonomics: The suitability for patients of different body types (such as obese and thin) and the ease of operation for medical staff were not adequately considered.

[0009] In view of this, it is particularly important to design and manufacture an auxiliary restraint device that is simple and easy to operate, reduces the involvement of medical staff, and can stably restrain the patient's lateral decubitus position, and to apply it in intraoperative nursing. Summary of the Invention

[0010] The purpose of this invention is to address the problem that maintaining a patient's lateral decubitus position requires direct intervention from medical staff, which increases the workload and difficulty of intraoperative nursing care and also increases the risk of surgical infection. Therefore, this invention proposes an auxiliary restraint device for lateral decubitus positioning during surgery.

[0011] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary restraint device for intraoperative lateral decubitus position includes a restraint garment shaped like a half-vest. Two first restraint straps are sewn to both the front and back ends of the placket of the restraint garment. A waist belt is sewn to the outer side of the waist opening of the restraint garment. The waist belt is equipped with a locking mechanism for adjusting the length of the waist belt and locking operation. A sleeve with an open inner side is detachably installed on the outer side of the shoulder opening of the restraint garment through a sleeve lock. A second restraint strap is sewn to both the front and back ends of the lower end of the sleeve.

[0012] As a further description of the above technical solution: The locking belt mechanism includes an adjusting buckle that is inserted and wound around the waist belt through the belt thread opening, two hollow toothed rollers that are symmetrically rotated and installed at both ends of the adjusting buckle and located on the outside of the waist belt, three sets of locking teeth that are equidistantly fixed on the two hollow toothed rollers and arranged in a ring array, a plastic toothed belt that is symmetrically sewn onto the waist belt and faces the three sets of locking teeth, a tooth groove that is opened on the plastic toothed belt and meshes with the locking teeth, and a locking roller part disposed between the two hollow toothed rollers.

[0013] As a further description of the above technical solution: The locking roller section includes a U-shaped slide bar movably installed between the lower ends of two hollow toothed rollers, an outer toothed ring fixed to the lower ends of the two hollow toothed rollers, and an inner toothed buckle block fixed below the two vertical ends of the U-shaped slide bar and meshing with the outer toothed ring.

[0014] As a further description of the above technical solution: The adjusting buckle is located between the two strap openings and is fixedly connected to a central support block that fits against the inner wall of the belt.

[0015] As a further description of the above technical solution: The sleeve locking part includes multiple positioning locking straps sewn at equal intervals on the outer side of the upper end of the sleeve and facing the shoulder opening of the restraint garment, a first magnetic piece fixed on the free end of the multiple positioning locking straps, a positioning locking seat sewn at equal intervals on the outer side of the shoulder opening of the restraint garment and corresponding to the position of the multiple positioning locking straps, and a second magnetic piece fixed on the inner side of the multiple positioning locking seats and magnetically locked with the first magnetic piece.

[0016] As a further description of the above technical solution: A protruding lifting button is fixedly connected between the positioning lock band and the outer side of the first magnetic plate, and a through hole is provided in the middle of the lifting button.

[0017] As a further description of the above technical solution: The restraint garment, the first restraint belt, the waist belt, the sleeves, and the second restraint belt are all made of medical antibacterial fabric.

[0018] As a further description of the above technical solution: The adjusting buckle, plastic toothed belt, hollow toothed roller, and positioning lock seat are made of PVC material.

[0019] As a further description of the above technical solution: The U-shaped slide bar is made of 316 stainless steel.

[0020] As a further description of the above technical solution: The positioning lock and lifting button are made of either rubber or woven material.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In this invention, the auxiliary restraint device is mainly composed of a restraint garment, a first restraint belt, a waist belt, an adjustment buckle, detachable sleeves, and a second restraint belt. The restraint garment, shaped like a half-vest, can be quickly put on the patient's body on the side away from the operating table. By operating the adjustment buckle on the waist belt, the restraint garment can be dynamically adjusted according to the patient's body shape. When the two sets of first restraint belts on the restraint garment are respectively tied to the armrests on both sides of the operating table, an isosceles triangle structure is formed between the restraint garment and the operating table. At this time, the patient can be stably maintained in a lateral position between the restraint garment and the operating table. This structure can effectively and stably restrain the patient's body or hands in an adjustable triangle on the operating table. A single medical staff member can operate to maintain the patient's lateral position and perform nursing operations on the surgical site, effectively reducing the workload and difficulty of intraoperative nursing operations, thereby improving the convenience, stability, and safety of intraoperative nursing operations.

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides a technical solution: an auxiliary restraint device for intraoperative lateral decubitus position, including a restraint garment 1 in the shape of a half vest structure. Two first restraint straps 2 are sewn to both the front and back ends of the placket 101 of the restraint garment 1. A waist belt 3 is sewn to the outside of the waist opening 102 of the restraint garment 1. The waist belt 3 is provided with a locking mechanism for adjusting the length of the waist belt 3 and locking operation. A sleeve 7 with an open inner side is detachably installed on the outside of the shoulder opening 103 of the restraint garment 1 through the sleeve lock part. A second restraint strap 10 is sewn to both the front and back ends of the lower end of the sleeve 7.

[0026] Specifically, such as Figure 1-3 As shown, the locking belt mechanism includes an adjusting buckle 4 that is inserted and wound around the waist belt 3 through the belt thread opening 401, two hollow toothed rollers 5 that are symmetrically rotated and installed at both ends of the adjusting buckle 4 and located on the outside of the waist belt 3, three sets of locking teeth 501 that are equidistantly fixed on the two hollow toothed rollers 5 and arranged in a ring array, a plastic toothed belt 301 that is symmetrically sewn onto the waist belt 3 and faces the three sets of locking teeth 501, a tooth groove 302 that is opened on the plastic toothed belt 301 and meshes with the locking teeth 501, and a locking roller part disposed between the two hollow toothed rollers 5.

[0027] The locking roller part includes a U-shaped slide bar 6 movably installed between the lower ends of the two hollow toothed rollers 5, an outer toothed ring 502 fixed to the lower ends of the two hollow toothed rollers 5, and an inner toothed buckle block 601 fixed below the two vertical ends of the U-shaped slide bar 6 and meshing with the outer toothed ring 502. When the inner toothed buckle block 601 on the U-shaped slide bar 6 slides into or out of the outer toothed ring 502 on the hollow toothed roller 5, the anti-deflection locking or unlocking operation of the two hollow toothed rollers 5 can be realized. Thus, by manually sliding and adjusting the position of the U-shaped slide bar 6, the locking or unlocking operation between the belt 3 and the adjusting buckle 4 after adjustment can be conveniently realized.

[0028] In addition, the middle part of the adjusting buckle 4 is fixedly connected to the central support block 402, which fits against the inner wall of the waist belt 3, between the two belt openings 401. On the one hand, it makes it convenient for the operator to hold the adjusting buckle 4, which can increase the contact friction and contact area between the adjusting buckle 4 and the hand, and facilitate the stable sliding adjustment operation of the adjusting buckle 4 on the waist belt 3. On the other hand, it can prevent the waist belt 3 from deviating and limit its position between the adjusting buckle 4 and the hollow toothed roller 5, ensuring that the plastic toothed belt 301 on the waist belt 3 can stably engage with the locking teeth 501 on the hollow toothed roller 5. Thus, the waist belt 3 can be adjusted and fixed by adjusting the adjusting buckle 4.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the sleeve locking part includes multiple positioning locking straps 8 equidistantly sewn to the outer side of the upper end of the sleeve 7 and facing the shoulder opening 103 of the restraint garment 1, a first magnetic suction piece 801 fixed to the free end of the multiple positioning locking straps 8, a positioning locking seat 9 equidistantly sewn to the outer side of the shoulder opening 103 of the restraint garment 1 and corresponding to the position of the multiple positioning locking straps 8, and a second magnetic suction piece 901 fixed to the inner side of the multiple positioning locking seats 9 and magnetically locking with the first magnetic suction piece 801. The arrangement of the first magnetic suction piece 801 and the second magnetic suction piece 901 enables quick positioning and magnetic fixing between the positioning locking straps 8 and the positioning locking seat 9, thereby improving the convenience and efficiency of assembling the sleeve 7 on the restraint garment 1.

[0030] Among them, a protruding lifting button 802 is fixedly connected between the outer side of the positioning lock band 8 and the first magnetic suction piece 801, which effectively increases the contact area between the medical staff's hand and the positioning lock band 8, so that the medical staff can easily pull the positioning lock band 8 upward and slide it out of the positioning lock seat 9 through the lifting button 802. A through hole is opened in the middle of the lifting button 802, which increases the contact friction and contact area between the medical staff's hand and the lifting button 802, and can reduce the occurrence of slippage and loss of hand during the process of the medical staff pulling the lifting button 802.

[0031] Specifically, such as Figure 1-5As shown, the restraint garment 1, the first restraint belt 2, the waist belt 3, the sleeves 7, and the second restraint belt 10 are all made of medical antibacterial fabric. While meeting the requirements of patient comfort and skin-friendliness, the restraint garment 1, the first restraint belt 2, the waist belt 3, the sleeves 7, and the second restraint belt 10 can have better antibacterial and bacteriostatic effects, which can reduce the occurrence of bacterial infection and cross-contamination during the use of the garment during surgery. In addition, in actual use, the binding rope can be selected to replace the first restraint belt 2 and the second restraint belt 10. At the same time, in order to facilitate further tightening after binding with the binding rope or the first restraint belt 2 and the second restraint belt 10, a manual retractor can be set on the binding rope or the first restraint belt 2 and the second restraint belt 10 to achieve further retracting and tightening operation after binding with the binding rope or the first restraint belt 2 and the second restraint belt 10.

[0032] The adjusting buckle 4, plastic toothed belt 301, hollow toothed roller 5, and positioning lock seat 9 are made of PVC material, which gives them excellent antibacterial and bacteriostatic effects, structural strength, anti-slip and wear-resistant properties, waterproof and flame-retardant properties, easy cleaning and maintenance, and multi-functional adaptability, meeting the needs of medical applications.

[0033] The U-shaped slide bar 6 is made of 316 stainless steel. While ensuring the high structural strength of the U-shaped slide bar 6, it also has excellent corrosion resistance, good biocompatibility, high temperature stability and hygiene safety, making it suitable for use in medical scenarios.

[0034] The positioning lock strap 8 and the lifting button 802 are made of either rubber or woven tape, which gives them flexible connection characteristics. This ensures that the sleeve 7 can be flexibly connected at multiple points to the outside of the shoulder opening 103 of the restraint garment 1, thereby improving the skin-friendliness and comfort of the overall wear after the sleeve 7 is fixed to the restraint garment 1. In actual use, woven tape is preferred as the material for the positioning lock strap 8 and the lifting button 802 because it has better tensile strength, bending strength, tear resistance and durability, making it suitable for reusable scenarios. Rubber material has better skin-friendliness and elasticity, but its tensile strength, bending strength, tear resistance and durability are average, making it suitable for single-use scenarios.

[0035] Working principle: When using this garment, if only auxiliary restraint of the patient's torso is required, the first step is for medical staff to take the restraint garment 1 separately, adjust the patient to a side-lying position, and then put the restraint garment 1 on the patient's torso, with the patient's hands coming out from the cuffs of the restraint garment 1; the second step is for medical staff to grasp and pull the U-shaped slide bar 6 outward according to the patient's body shape, so that the inner toothed buckle 601 on the U-shaped slide bar 6 slides away from the locking teeth 501 of the two hollow toothed rollers 5. At this time, the locking state of the two hollow toothed rollers 5 on the adjusting buckle 4 is released, and the adjusting buckle 4 can be slid and adjusted on the waist belt 3. When the restraint garment 1 just covers half of the patient's torso, and the adjusting buckle 4 can stably fit the patient's waist. When the U-shaped slide bar 6 is slid towards the hollow toothed roller 5, the inner toothed buckle 601 on the U-shaped slide bar 6 can slide and buckle into the outer toothed ring 502 on the hollow toothed roller 5, thereby locking the two hollow toothed rollers 5 to the adjusting buckle 4 to prevent deflection. Under the meshing action of the locking teeth 501 on the hollow toothed roller 5 and the tooth groove 302 on the plastic toothed belt 301, the adjusting buckle 4 can be stably fixed on the waist belt 3. In the third step, after binding the two first restraint straps 2 on the front and back sides of the restraint garment 1 to the armrests of the operating table, the patient's body can be triangularly fixed between the restraint garment 1 and the operating table, thus stably restraining the patient's body to a lateral decubitus position, and subsequent intraoperative nursing operations can be carried out.

[0036] When it is necessary to provide comprehensive auxiliary restraint to the patient's body and hands, the first step is for medical staff to take the restraint garment 1 and sleeves 7, and to attach the multiple positioning lock straps 8 on the sleeves 7 to the positioning lock seats 9 on the restraint garment 1. Under the magnetic attraction of the first magnetic plate 801 and the second magnetic plate 901, the sleeves 7 can be assembled and installed between the cuff and shoulder opening 103 of the restraint garment 1. The patient is then adjusted to a lateral decubitus position, and the patient's hands are adjusted and placed parallel to the body, with the palms facing down. The first step involves placing the restraint garment 1 around the patient's legs, wrapping it between the patient's torso and hands. The second step, depending on the patient's body shape, involves the medical staff grasping and pulling outwards on the U-shaped sliding rod 6. This slides the inner toothed buckle 601 on the U-shaped sliding rod 6 away from the locking teeth 501 of the two hollow toothed rollers 5, releasing the locking state of the two hollow toothed rollers 5 on the adjusting buckle 4. The adjusting buckle 4 can then be slid and adjusted on the waist belt 3 until the restraint garment 1 just covers half of the patient's torso, and the adjusting buckle 4 is just positioned correctly. When the U-shaped slide bar 6 is stably fitted to the patient's hand, it can be slid towards the hollow toothed roller 5. At this time, the inner toothed buckle 601 on the U-shaped slide bar 6 can slide and engage with the outer toothed ring 502 on the hollow toothed roller 5, thereby locking the two hollow toothed rollers 5 onto the adjusting buckle 4 to prevent deflection. Under the meshing action of the locking teeth 501 on the hollow toothed roller 5 and the tooth groove 302 on the plastic toothed belt 301, the adjusting buckle 4 can be stably fixed on the waist belt 3. The third step is to adjust the two sides of the restraint garment 1. After the first restraint strap 2 is tied to the armrest of the operating table, the patient's torso can be triangularly fixed between the restraint garment 1 and the operating table. In the fourth step, adjust the open sleeve 7 to cover the patient's hand, and adjust the cuff of the sleeve 7 to fit the patient's hand. Then, tie the second restraint strap 10 to the armrest of the operating table. At this time, the patient's torso and hand are both restrained, and the patient's body position can be stably restrained to a lateral decubitus position, so that subsequent intraoperative nursing operations can be carried out.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
