Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a head, neck, chest and waist fixator. Background Art

[0002] In the prior art, the scenarios where head, neck, thorax and waist fixation is used are medical positioning cushions during spinal surgery and head, neck, thorax and waist braces for postoperative recovery. Medical positioning cushions pose a great risk when the patient's body needs to be moved or turned over during spinal surgery. For example, patent CN 215840206 U discloses a new type of posterior cervical spine surgery positioning cushion, in which an auxiliary frame and an auxiliary cushion are provided on the cushion of the operating bed, the auxiliary frame is located at the patient's head position, and the auxiliary cushion is located at the patient's body position; the auxiliary cushion is provided next to the auxiliary frame; and the operating bed is also provided with a fixing portion for fixing the auxiliary frame and the auxiliary cushion. In particular, during cervical spine surgery, it is necessary to ensure the relative fixation of the head, neck and torso when moving or turning over, and positioning cushions are difficult to meet this requirement.

[0003] In addition, the metal fixator frame used to fix the head during surgery is very painful for the patient. Common ones include skull clamps, which use metal nails to fix the patient's head. There are other structural fixation methods in the prior art, such as patent CN 113230078 B, a device for fixing the patient's head during cervical spine surgery, which uses a reduction motor to drive the gear to reciprocate on the rack, thereby driving the drive pin to move in the dovetail slot: when the drive pin is away from the fixed pin, multiple arc-shaped cross arms are extended and cross-shaped, covering the patient's head in the spherical space formed by the arc-shaped cross arms, which is convenient for subsequent fixation of the patient's head; when the drive pin is close to the fixed pin, multiple arc-shaped cross arms are contracted and cross-shaped, and the arc-shaped cross arms are moved away from the patient's head, thereby achieving quick and portable head fixation. However, this structure is complex, costly, and inconvenient for the patient to move or flip sideways.

[0004] Furthermore, existing head, neck, thoracolumbar braces for postoperative recovery are not very effective at securing the head. They typically support the patient's mandible and then secure it by supporting the back of the head. This structure covers few details of the body's contours, and the mandible is inherently movable. Combined with the multiple components assembled together, the fixation effect is significantly poor. Therefore, an easy-to-use head, neck, thoracolumbar fixator is essential for spinal surgery and postoperative recovery. Utility Model Content

[0005] In view of this, it is necessary to provide a head, neck, thorax and waist fixator to solve the technical problem in the existing technology that it is difficult to ensure the relative fixation of the head, neck and torso during spinal surgery and postoperative recovery.

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0030] like Figure 1-4 As shown, the utility model provides a head, neck, chest and waist fixator, including a front fixing part 1, a back fixing part 2 and a binding part 3. The front fixing part 1 and the back fixing part 2 are both 3D printed brace models, which are modeled on the patient's body surface. The front fixing part 1 includes a chest 11, a first side waist 12, a first neck 13 and a face 14. The first side waist 12 extends from both sides of the chest 11 to fit the waist, creating a fit extending from the chest to the waist. The first neck 13 extends upward from the top of the chest 11 to fit the neck, wherein the first neck 13 can also have a certain gap with the neck to reduce pressure on the neck. The face 14 extends upward from the first neck 13 to fit the facial contour, and the face is covered and wrapped by the face 14, thereby limiting the position of the face. Among them, an opening 141 is provided on the front of the face 14, which is an important position for fixing the patient's head with the face 14, and the opening 141 is used to expose the eyes, nose and mouth to prevent them from being blocked. The opening 141 is T-shaped, which can expose the eyes, nose and mouth with minimal space, and the opening 141 is concave along the contours of the brow arch and cheekbone at the brow arch and cheekbone and forms a first recess 1411 and a second recess 1422 embedded in the brow arch and cheekbone respectively. The first recess 1411 and the second recess 1422 are respectively embedded in the brow arch and cheekbone, the cheeks on both sides and the brow bone above. The first recess 1411 and the two second recesses 1422 here form an embedded triangular support part, which can be quickly positioned when the patient fits his face into the face 14, and the head can be fixed with the assistance of the rear fixing part 2 and the binding part 3. The back fixing part 2 is made to fit the contours of the back, back of the neck, and back of the head, and is used to fit the patient's back, flanks, back of the neck, and back of the head for support. The binding part 3 is arranged between the front fixing part 1 and the back fixing part 2, and is used to detach the front fixing part 1 and the back fixing part 2 for adjusting the tightness. After the operation of moving and flipping the side is completed, the detachable binding part 3 can be removed from the side corresponding to the surgery, so that the surgery can continue while the body position is fixed.

[0031] In use, before surgery, the patient lies flat and wears the front and back fixing parts 1 and 2, which are fixed by the binding parts 3. During surgery, when the patient needs to be moved and turned, the binding parts 3 fix the front and back parts of the fixator, and the front and back fixing parts 1 and 2 keep the patient's head, neck, chest and waist in a fixed position, making the patient more stable during turning and less likely to shift.

[0032] Another usage environment is that during the recovery period, the patient wears the front fixing part 1 and the back fixing part 2, and fixes them with the binding part 3, which can effectively support and fix the head, neck, chest and waist. In addition, the face 14 is opened 141 for the eyes, nose and mouth to be used normally, and the ears are not compressed in the gap. The chest and back parts are narrowed in the upper part to reserve space for the shoulders to move, making it more comfortable for patients to use.

[0033] Understandably, the front and rear pieces of the fixator are both printed at one time, with a stable and reliable structure, capable of fixing the head, neck, chest and waist at one time; the structural printing material of the fixator is PLA or other environmentally friendly, degradable, non-toxic and harmless polymer materials, which are very light; the support points selected for facial fixation 14 are positions such as the zygomatic bones and brow arches, which are conducive to positioning and fixation, and the head is less likely to shift during movement and flipping; it can enable the patient to maintain the overall shape before surgery, preventing the patient's condition from changing due to possible positional shifts before surgical preparation; it plays a fixing role in the process of sending the patient to the surgery, facilitating transfer; it provides reliable assistance when the patient needs to be moved and flipped during the operation; it still plays a big role in the transfer and a certain recovery period after the operation; it has a high degree of fit and comfort, a stable and reliable structure, and is simple to operate and easy to use.

[0034] In a certain embodiment, in order to achieve faster alignment and greater stability when worn, a chin support portion 142 is provided on the face portion 14 for supporting the patient's mandible, and the top of the chest-attached part 11 is bent along the clavicle contour to form a locking portion 111 for forming a locking area between it and the side opposite to the chin support portion 142, so that the support of the neck area is more stable and has the effect of preventing up and down sliding.

[0035] Furthermore, in order to maintain breathability and reduce pressure on the neck, a through hole 1301 is opened on the front of the first neck portion 13. The position of the through hole 1301 corresponds to the position of the Adam's apple, preventing excessive pressure on the patient's neck during use, affecting the comfort of use.

[0036] In a certain embodiment, in order to facilitate the fixation of the front patch fixing part 1 and the back patch fixing part 2, the binding part 3 includes a fixing buckle 31 and a Velcro strap 32, and several pairs of the fixing buckles 31 are respectively arranged on the front patch fixing part 1 and the back patch fixing part 2. One Velcro strap 32 passes through a pair of the fixing buckles 31 respectively located on the front patch fixing part 1 and the back patch fixing part 2. The Velcro strap 32 is easy to stick and separate. When fixing is required, it can be directly pasted on the A side and B side of the Velcro.

[0037] It can be understood that a single Velcro strap 32 passes through two corresponding fixing buckles 31 on the front fixing part 1 and the back fixing part 2 in sequence, and then folded back so that the A side and B side of the Velcro can be pasted, and then tightened to paste.

[0038] Among them, the fixing buckle 31 includes a fixing plate 311, a screw 312 and a ring 313. The ring 313 is rotatably connected to the fixing plate 311. The fixing plate 311 is fixed to the front fixing part 1 and the rear fixing part 2 by the screw 312, which is convenient for installation and disassembly.

[0039] Specifically, there are ten fixing buckles 31 on the front fixing part 1 and the back fixing part 2, four on the first side waist and the second side waist, two on the back of the head and the mask, four on the chest and the upper half of the back, and they are located on the upper and lower sides of the arms respectively. The upper fixing buckles are symmetrical with the median vertical line and are arranged diagonally upward in opposite directions, so that the Velcro strap 32 can be diagonally passed over the upper shoulder and then connected to the fixing buckle on the back to obtain a more stable binding effect.

[0040] In a certain embodiment, the rear fixing part 2 includes a back part 21, a second side waist part 22, a second neck part 23 and a back of the head 24. The second side waist part 22 extends from both sides of the back part 21 to fit the waist. The second neck part 23 extends upward from the top of the back part 21 to fit the back of the neck. The back of the head 24 extends upward from the top of the second neck part 23 to fit the back of the head, thereby supporting the back, waist, back of the neck and back of the head.

[0041] It can be understood that under the support of the rear fixing part 2, the position of the back of the head is relatively stable. Combined with the front fixing part 1, the entire brain can be fixed, and there is no need for metal parts to poke into the patient's brain. It is more comfortable and reduces the patient's pain.

[0042] In a certain embodiment, in order to facilitate exposure of the ears and movement of the arms, the back of the head 24 is opposite to the two sides of the face 14 and forms a gap. The gap is used to expose the ears and extend to the neck, chest and waist, reducing consumables while providing space for the ears and arms.

[0043] In one embodiment, in order to further enhance the stability of the binding, the binding member 3 further includes a neck strap, which is arranged between the outer sides of the first neck portion 13 and the second neck portion 23 . The neck strap may also be a Velcro strap 32 .

[0044] It can be understood that the additional Velcro strap on the neck can provide sufficient stability at the neck and further stabilize the overall structure.

[0045] In a certain embodiment, in order to improve comfort and prevent slipping, the front patch fixing part 1 and the rear patch fixing part 2 are both provided with EVA foam perforated linings. The EVA foam perforated linings are included on the front and back sides of the front patch fixing part 1 and the rear patch fixing part 2. When fitted to the patient, they have an anti-slip effect and make the contact surface relatively soft, thereby improving comfort.

[0046] In one embodiment, in order to improve the breathability, ventilation holes 4 are provided on the front fixing member 1 and the rear fixing member 2, so as to reduce the stuffiness and heat when the fixing member is used during the later recovery period.

[0047] Furthermore, the shape of the ventilation hole 4 is elliptical, and the shape of the through hole 1301 is circular.

[0048] The specific working process of the present invention is as follows: during surgery, when the patient needs to be moved and turned, the front and rear pieces of the fixator are fixed by the binding member 3, that is, the front fixing member 1 and the rear fixing member 2 are fixed, so that the patient's head, neck, chest and waist position are maintained. After the movement and turning operation is completed, the binding member 3 is untied and the piece corresponding to the side to be operated on is removed, so that the operation can continue while the patient's position is fixed.

[0049] The entire workflow is complete, and all contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0050] The head, neck, chest and waist fixator in this utility model is mainly manufactured by the following 3D printing method, which includes the following steps:

[0051] S1. Use a 3D scanner to collect patient surface data, and restore the 3D model of the patient's body surface through reverse modeling. Build a 3D printed brace model based on this data, and then segment the model into a front-attached fixing piece that fits the patient's front and a rear-attached fixing piece that fits the patient's back.

[0052] S2. The face retains the cheekbones and forehead brow arches as support points, and the eyes, nose and mouth are exposed. The back of the head fits the contour of the brain to stabilize the head.

[0053] S3, the face further retains the support of the mandible;

[0054] S4: For chest and back fitting, the area from the front chest or back to the abdomen is retained, and part of the waist on both sides of the abdomen is retained. For chest fitting, the clavicle position is retained to fit the contour, and for back fitting, the top is retained to fit the contour of the shoulder.

[0055] S5, the face and the back of the head are kept away from the ears, leaving relatively equidistant gaps;

[0056] S6, chest and back are narrowed in the upper part to reserve space for shoulder movement;

[0057] S7. The front and rear fixings are perforated for ventilation.

[0058] S8. Make a hole for the Adam's apple on the first neck and a hole for ventilation on the second neck.

[0059] The printing material is PLA or other environmentally friendly, biodegradable, non-toxic, and harmless polymer materials. Using these steps, 3D printing can produce a head, neck, chest, and waist brace that can stably position and immobilize the patient, preserving their overall shape before surgery. It also offers a highly comfortable fit and a stable and reliable structure.

[0060] In addition, the strap part 3 is directly installed on the front fixing part and the back fixing part, wherein the fixing buckle 31 is made of metal, and the Velcro strap can be directly used in a suitable size.

[0061] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
