Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary appliances, in particular to an auxiliary support device for pediatric head and neck surgery. Background Art

[0002] In pediatric head and neck surgery, adequate exposure of the surgical field and stable patient position are key factors in ensuring surgical accuracy and safety. However, existing head and neck support devices are mostly designed based on adult anatomy and are difficult to adapt to the unique head and neck size and physiological curvature of children (especially infants), leading to the following technical pain points:

[0003] Insufficient adaptability: Children's heads and necks are small and highly flexible, and existing fixation devices (such as universal headrests or horseshoe-shaped headrests) cannot fit tightly, are easily displaced during surgery, and increase the risk of accidental tissue injury.

[0004] Limited exposure: Traditional devices have low degrees of adjustment freedom (e.g., only support supine or lateral lying), making it difficult to achieve multi-angle posture requirements such as hyperextension of the head and neck and lateral deviation, affecting the exposure of the surgical field, especially deep areas such as the infratemporal fossa and cervicothoracic junction.

[0005] Conflict between stability and safety: To fix the head and neck, some devices require excessive clamping or compression, which may cause scalp crush or cervical ligament damage in children; while flexible support is difficult to resist the intraoperative operating force, resulting in body position deviation.

[0006] Therefore, there is an urgent need for a new auxiliary support device for pediatric head and neck surgery to provide an effective solution to the defects of the existing technology. Summary of the Invention

[0007] The object of the present invention is to provide an auxiliary support device for pediatric head and neck surgery to solve the problems raised in the above background technology.

A threaded sleeve extending outward is provided at the center position of the slider groove, and a locking screw is threadedly connected to the threaded sleeve. One end of the locking screw is rotatably connected to the slider, and the other end extends out of the threaded sleeve and is fixedly connected to a handle.

[0011] Furthermore, the inlet end hinge seat, the distal end hinge seat and the single-section hinge seat are all double-plate structures, and the hinge plate is a single-plate structure; the end of the inlet end hinge seat and the distal end hinge seat are provided with a single axial hole, and each two ends of the single-section hinge seat are provided with an axial hole, and the inner end of the axial hole is surrounded by a ring array with teeth, and each two ends of the hinge plate are passed through a rotating shaft, and the rotating shaft is rotatably connected to the axial hole, and the inner end of the hinge plate is surrounded by a ring array with convex teeth, and the convex teeth are snap-fitted with the teeth, and the axis center of the rotating shaft is provided with a penetrating column hole, and a column is inserted in the column hole, and a threaded hole is provided at the column core position of the column, and a locking column screw is threadedly connected in the threaded hole, and a limiting disk is provided at one end of the column, and a twist handle is provided at one end of the locking column screw, and a pressure plate is sleeved on the locking column screw, and the limiting disk and the pressure plate are respectively pressed on the two ends of the rotating shaft.

The hinge plate 18 is hinged to the inlet end hinge seat 15, the distal end hinge seat 27, and the single-section hinge seat 26 to form a chain structure, and each node of the chain structure can adjust the angle and the angle position can be locked.

[0034] A slider groove 10 is provided on the circumferential inner wall of the vertical axis rotating sleeve 9, and a slider 12 with an arc-shaped plate structure is slidably installed in the slider groove 10. Strip protrusions are provided on the circumferential outer wall of the vertical axis rotating shaft 14 and the circumferential inner wall of the slider 12. A threaded sleeve 11 extending outward is provided at the center of the slider groove 10, and a locking screw 13 is threadedly connected to the threaded sleeve 11. One end of the locking screw 13 is rotatably connected to the slider 12, and the other end extends out of the threaded sleeve 11 and is fixedly connected to a twist handle.

[0035] The inlet end hinge seat 15, the distal end hinge seat 27, and the single-section hinge seat 26 are all double-plate structures, and the hinge plate 18 is a single-plate structure; a single shaft hole 17 is provided at the end of the inlet end hinge seat 15 and the distal end hinge seat 27, and a shaft hole 17 is provided at each end of the single-section hinge seat 26. A tooth groove 16 is distributed in a circular array around the inner end of the shaft hole 17, and a rotating shaft 20 is passed through each end of the hinge plate 18. The rotating shaft 20 is rotatably connected to the shaft hole 17, and the inner end of the hinge plate 18 is There are convex teeth 19 distributed in the annular array, and the convex teeth 19 are snap-fitted with the tooth grooves 16.

A pressure plate 22 is sleeved on the locking column screw 23, and the limiting disk 25 and the pressure plate 22 are respectively pressed on the two ends of the rotating shaft 20.

[0036] Working principle of this embodiment:

[0037] In this embodiment, the horizontal rotation of the contoured face support 1 (ie, left and right deflection of the head and neck) is achieved by rotating the vertical axis rotating shaft 14 in the vertical axis rotating sleeve 9, and the locking mechanism (slider 12, locking screw 13) can fix the angle.

[0038] The chain-like structure (consisting of the inlet hinge seat 15, a single-section hinge seat 26, a distal hinge seat 27, and a hinge plate 18) articulates at multiple nodes to achieve pitch, lateral, and hyperextension of the head and neck. The protruding teeth 19 at each node mesh with the tooth grooves 16 to provide multi-angle positioning. The locking screw 23 compresses the insert 24 and secures the rotating shaft 20, ensuring stability.

[0039] The contoured face support 1 fits the child's facial contours, distributing pressure. The flexible hinged chain structure adjusts the curvature of the head and neck to suit surgical needs, avoiding localized pressure. The mounting base 7 is secured to the edge of the operating table, with a vertically rotating sleeve 9 and chain structure providing dual locking, resisting intraoperative forces and preventing displacement.

[0040] In this embodiment, the contoured facial support 1 is designed based on the facial anatomy of children and is combined with a multi-section hinged chain to adapt to the size and curvature of the head and neck of children of different ages, solving the problem of displacement caused by the oversize of traditional devices. The vertical axis rotation axis 14 realizes horizontal rotation, and the chain structure supports multi-dimensional adjustment such as hyperextension and lateral deviation of the head and neck (such as the 15° indexing locking of the hinged plate 18 and the tooth groove 16), which significantly improves the exposure effect of deep areas such as the infratemporal fossa. The engagement of the tooth groove 16 and the convex teeth 19 provides a rigid lock to avoid the displacement risk of flexible support; the dispersed pressure design of the contoured facial support 1 reduces pressure injuries and solves the contradiction of excessive clamping or insufficient support of traditional devices. This embodiment achieves safe, stable and precise posture support during pediatric head and neck surgery through contoured fitting and multi-degree-of-freedom adjustment mechanism.

[0041] Example 2: Please refer to Figures 8-10 , an auxiliary support device for pediatric head and neck surgery, which differs from Example 1 in that a brow hole 2, a nostril 3 and a mouth hole 4 are opened on the contoured face support 1.

[0042] A frontal bone avoidance groove 5 is provided at the distal end of the contoured face support 1 .

[0043] Concha avoidance grooves 28 are provided on both sides of the contoured face support 1 .

[0044] The contoured facial support 1 is custom-made based on the three-dimensional modeling data of the child's face.

[0045] Working principle of this embodiment:

[0046] In this embodiment, the brow hole 2, nostril 3, and mouth hole 4 ensure facial fit while avoiding compression of key physiological structures. The brow hole prevents squeezing of the brow arch and reduces the risk of postoperative congestion. The nostril ensures that the child can breathe freely and avoids the hidden danger of suffocation caused by traditional masks. The mouth hole facilitates anesthesia intubation or intraoperative oral operation, improving the safety of the operation. During the operation, the child's face is naturally embedded in the contoured face support 1, and the hole position precisely corresponds to the anatomical landmark, which not only provides stable support but also avoids local pressure concentration. The frontal bone avoidance groove 5 is adapted to the protruding frontal bone feature of children to avoid scalp injury caused by hard contact, and is especially suitable for long-term surgery. The external ear avoidance groove avoids the auricle structure to prevent collision of instruments or pressure deformation of the ear during surgery, and is convenient for disinfection and draping of the surgical area.

[0047] The contoured facial support 1 in this embodiment is customized through 3D modeling, ensuring that it contacts only non-sensitive areas (such as the cheekbones and mandible), distributing pressure to load-bearing bony structures and improving comfort. This customized 3D modeling is based on preoperative CT / MRI reconstruction of the patient's facial contours, or on individualized data obtained through 3D scanning.

[0048] The hole-slot structure of this embodiment completely avoids compression of key parts, and is especially suitable for the thin and delicate skin of infants and young children. The hole and avoidance groove design avoids obstruction of the surgical field and facilitates deep operations.

[0049] Example 3: Please refer to Figures 1 to 10 , an auxiliary support device for pediatric head and neck surgery, which differs from Example 1 in that the vertical axis rotation axis 14 is driven to rotate by a servo motor, and each node of the chain structure formed by the hinged plate 18 and the inlet end hinge seat 15, the distal end hinge seat 27, and the single-section hinge seat 26 is also driven to rotate by a servo motor.

[0050] Working principle of this embodiment:

[0051] The servo motor (not shown) directly drives the vertical axis rotating shaft 14 to rotate in the vertical axis rotating sleeve 9, thereby achieving precise adjustment of the horizontal plane (left and right deflection) of the contoured face support 1. The servo motor has a built-in high-precision encoder that can provide real-time feedback on the rotation angle and maintain the set position through a braking mechanism or a motor self-locking function, without relying on a mechanical locking screw 13 (but it can still be retained as a redundant lock). Each articulated node (the connection between the inlet end articulated seat 15, the single-section articulated seat 26, the distal end articulated seat 27 and the articulated plate 18) is integrated with a micro servo motor to drive the rotating shaft 20 to rotate, changing the angle between adjacent articulated plates to achieve head and neck pitch, lateral deviation and hyperextension. The servo motors at each node coordinate their movements through a central controller, and can be programmed to achieve complex body position adjustments (such as simultaneous hyperextension + lateral deviation) to improve the efficiency of surgical field exposure.

[0052] The servo motor in this embodiment can achieve body position adjustment in seconds, reducing manual operation time; eliminating the manual tightening step, maintaining the angle through motor self-locking or electromagnetic braking to avoid the risk of loosening; storing commonly used body position parameters to adapt to different surgical needs and improve the consistency of repeated operations.
