Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an arm splint for pediatric surgical operations. Background Art

[0002] As an independent branch of surgery, the clinical characteristics of pediatric surgery are mainly reflected in the specificity of the diagnosis and treatment objects and the specificity of technical operations. There are significant differences between children and adults in terms of anatomical structure, physiological function and psychological cognition. Especially in perioperative management, this difference places higher demands on the quality of surgical cooperation. Because the development of children's nervous system is not yet complete, they often have characteristics such as weak autonomous movement control ability, high pain sensitivity, and poor environmental adaptability during surgery, which manifest as clinical phenomena such as difficulty in maintaining body position and involuntary limb swinging. Such unexpected limb movements may not only cause safety hazards such as surgical field contamination and instrument displacement, but also significantly prolong the anesthesia induction time and the duration of the surgical operation, directly affecting the safety margin of the operation and the work efficiency of the medical team.

[0003] Conventional limb fixation devices currently used in clinical practice are mostly designed based on adult anatomical parameters. They have problems such as poor matching between the fixation surface and the child's limb morphology, uneven pressure distribution, and lack of joint range of motion adjustment mechanism, which can easily lead to fixation failure or local compression injuries.

[0004] Therefore, a pediatric surgical arm splint is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an arm splint for pediatric surgery, which solves the above-mentioned technical problems.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an arm splint for pediatric surgical operations, comprising a main body, the main body comprising a mounting seat, a C-arm sleeve being mounted on the surface of the mounting seat, a Velcro fastener being fixed at one end of the C-arm sleeve, a Velcro sub-strip being fixed at the end of the C-arm sleeve away from the Velcro fastener, the Velcro sub-strip being adhesively connected to the Velcro fastener, an extension plate being fixedly mounted at the end of the mounting seat, a clamping sleeve being fixed at the end of the extension plate away from the mounting seat, an arc-shaped limiting groove being concavely provided on the surface of the mounting seat, a limiting slider being slidably sleeved on the inner wall of the arc-shaped limiting groove, and the limiting slider being fixedly mounted on the surface of the C-arm sleeve.

[0007] Preferably, a tightening plate is extended and fixedly installed at the end of the jacket, a bolt is threadedly installed through the surface of the tightening plate, and a rubber pad is fixed on the inner wall of the jacket.

[0008] Preferably, the extension plate is arranged in an S-shaped structure, and a plurality of through grooves are formed through the surface of the extension plate.

[0009] Preferably, a connecting block is fixedly installed on the end of the extension plate away from the sleeve, and a T-slot is recessed on the end of the connecting block away from the extension plate. A T-block is slidably sleeved on the inner wall of the T-slot, and the T-block is fixedly installed on the surface of the mounting seat. A spring is fixedly installed on the end of the T-block, and the back end of the spring is fixedly installed on the inner wall of the T-slot.

[0010] Preferably, the end surface of the C-arm sleeve is concavely provided with a groove, the inner wall of the groove is symmetrically fixed with rotating shafts, and handles are installed on the two rotating shafts for rotation together, and the surface of the groove is concavely provided with a pulling groove.

[0011] Preferably, an airbag cover is detachably mounted on the inner wall of the C-arm cover, a through hole is provided on the surface of the C-arm cover, and the airbag cover is movably engaged with the through hole.

[0012] Preferably, the handle surface fixing sleeve is provided with a silicone sleeve.

[0013] Compared with related technologies, the arm splint for pediatric surgery provided by the present invention has the following beneficial effects:

[0014] The present invention provides an arm splint for pediatric surgical operations. The method comprises inserting the child's arm into a C-arm sleeve, then pulling the Velcro tape to adhere to the surface of the Velcro tape, and the adhesion of the Velcro tape and the Velcro tape drives the two ends of the C-arm sleeve to approach each other, so that the inner diameter of the C-arm sleeve becomes smaller and tightened to clamp the child's arm. Due to the extension of the extension plate, the clamping sleeve is arranged on the bedside to restrict the child's arm, and the child's arm can be quickly fixed. When the child's arm twists, the limiting slider slides on the inner wall of the arc-shaped limiting groove, so that the C-arm sleeve rotates to a certain extent, providing a buffer when the child's arm twists, and avoiding the dislocation of the arm joint caused by forced twisting.

[0015] The present invention provides an arm splint for pediatric surgical operations. After the child's arm is clamped and fixed by a C-arm sleeve, the child may twitch due to discomfort, thereby driving a T-shaped block to slide on the inner wall of the T-shaped slot to effectively buffer the arm, thereby avoiding the accidental dislocation caused by strong twitching of the arm. During the sliding process of the T-shaped block, the spring is squeezed, so that the twitching force of the child's arm is increased, and the twitching frequency and distance of the child's arm are reduced.

[0023] See also Figures 1-6 The present invention provides a technical solution, including a main body 1, which includes a mounting base 11, a C-arm sleeve 12 is installed on the surface of the mounting base 11, one end of the C-arm sleeve 12 is fixed with a magic mother patch 19, and the end of the C-arm sleeve 12 away from the magic mother patch 19 is fixed with a magic son patch 2, and the magic son patch 2 is glued together with the magic mother patch 19, an extension plate 14 is fixedly installed on the end of the mounting base 11, and a clamping sleeve 15 is fixed on the end of the extension plate 14 away from the mounting base 11, and an arc-shaped limiting groove 18 is concavely opened on the surface of the mounting base 11, and a limiting slider 21 is slidably sleeved on the inner wall of the arc-shaped limiting groove 18, and the limiting slider 21 is fixedly installed on the surface of the C-arm sleeve 12;

[0024] By inserting the child's arm into the C-arm sleeve 12, and then pulling the Velcro 2 to stick it to the surface of the Velcro 19, and the adhesion of the Velcro 2 and the Velcro 19 drives the two ends of the C-arm sleeve 12 to approach each other, so that the inner diameter of the C-arm sleeve 12 becomes smaller and tightened to clamp the child's arm, and due to the extension of the extension plate 14, the sleeve 15 is placed on the side of the bed to restrict the child's arm, which can quickly fix the child's arm, and when the child's arm twists, the limiting slider 21 slides on the inner wall of the arc-shaped limiting groove 18, causing the C-arm sleeve 12 to rotate to a certain extent, providing a buffer for the child's arm when twisting, and avoiding the situation where forced twisting causes dislocation of the arm joints.

[0025] A tightening plate 16 is fixedly installed on the end of the jacket 15, and a bolt 17 is threadedly installed on the surface of the tightening plate 16. A rubber pad is fixed on the inner wall of the jacket 15;

[0026] After the jacket 15 is put on the bedside, the bolts 17 are tightened to gradually bring the tightening plates 16 at both ends of the jacket 15 closer together, so that the jacket 15 tightly clamps the bedside to fix it, and the setting of the rubber pad increases friction, reduces wear, and increases service life.

[0027] The extension plate 14 is arranged in an S-shaped structure, and a plurality of through grooves are formed through the surface of the extension plate 14;

[0028] The extension plate 14 can undergo a certain degree of tensile deformation, thereby increasing the force required for the child's arm to twist, while the twisted arm will not affect the surgical process.

[0029] A connecting block 22 is fixedly mounted on the end of the extension plate 14 away from the jacket 15. A T-slot 23 is recessed on the end of the connecting block 22 away from the extension plate 14. A T-block 25 is slidably sleeved on the inner wall of the T-slot 23. The T-block 25 is fixedly mounted on the surface of the mounting seat 11. A spring 24 is fixedly mounted on the end of the T-block 25. The back end of the spring 24 is fixedly mounted on the inner wall of the T-slot 23.

[0030] After the child's arm is clamped and fixed by the C-arm sleeve 12, it may twitch due to discomfort, which in turn drives the T-block 25 to slide on the inner wall of the T-slot 23 to effectively buffer, thereby avoiding the accidental dislocation caused by strong twitching of the arm, and squeezing the spring 24 during the sliding process of the T-block 25, thereby increasing the twitching force of the child's arm and reducing the twitching frequency and distance of the child's arm.

[0031] The end surface of the C-arm sleeve 12 is concavely provided with a groove 26, and the inner wall of the groove 26 is symmetrically fixed with a rotating shaft 29. The two rotating shafts 29 are mounted with a handle 27 for rotation together. The surface of the groove 26 is concavely provided with a lifting groove 28;

[0032] After the child's arm is inserted into the C-arm sleeve 12, the handle 27 is moved from the lifting groove 28 so that the handle 27 is rotated out from the groove 26, so that the child's palm can hold the handle 27, providing a reliable force point for the child's hand, reducing the child's discomfort and shaking, and facilitating the normal progress of the operation.

[0033] An airbag cover 13 is detachably mounted on the inner wall of the C-arm cover 12. A through hole is provided on the surface of the C-arm cover 12, and the airbag cover 13 is movably engaged with the through hole.

[0034] The airbag sleeve 13 is used to apply pressure to the child's arm, and at the same time, the comfort of the child's arm when it is fixed is improved, so that the child's arm is cushioned when it is shaking, avoiding bumps and strangulation.

[0035] The surface of the handle 27 is fixed with a silicone sleeve;

[0036] This makes it more comfortable for the child's hand to hold the handle 27 , and at the same time increases the friction between the handle 27 and the hand, making it easier for the child's hand to hold the handle 27 .
