Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically referring to a surgical head and neck postoperative auxiliary support and positioning device. Background Technology

[0002] Head and neck surgery is an extension of otolaryngology, which gradually developed to meet the clinical diagnosis, treatment, and research needs of malignant tumors of the head and neck and otolaryngology. Surgical treatment is frequently used for head and neck diseases, especially thyroid diseases, submandibular gland diseases, parotid gland diseases, and neck tumors.

[0003] After surgery on the head and neck, it is necessary to strictly limit the range of motion of the patient's head and neck to avoid intentional or unintentional large-scale movements or impacts from foreign objects that could cause surgical failure or increase secondary damage. This is especially true for treatment of the parotid gland, which requires local pressure bandaging after surgery. Because there are many duct-like tissues around the parotid gland, if pressure bandaging is not applied or is insufficient, saliva and other secretions can enter the surgical area, increasing the risk of local soft tissue infection and the possibility of long-term wound non-healing. Current techniques for pressure bandaging often involve directly wrapping the pressure bandage around the patient's chin. When the patient needs to adjust the tightness of the pressure bandage according to their own condition or the swelling of the affected area, they need to go to the hospital to have the pressure bandage reapplied by medical staff, which is time-consuming and laborious.

[0004] Existing head and neck surgery postoperative neck support and positioning devices often only support and position the neck, without restricting the patient's head rotation, resulting in weak positioning effectiveness. Most support devices that provide dual head and neck positioning employ a protective structure that covers the entire head and neck, leading to poor breathability and an inability to adjust to different head sizes or neck lengths, resulting in limited applicability and discomfort for patients, hindering their daily lives after surgery. Furthermore, existing support devices do not consider the need for pressure bandaging and cannot meet the requirements for head and neck support and the tightness of pressure bandaging at different stages of recovery. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a surgical head and neck postoperative auxiliary support and positioning device. Designed for patients requiring pressure bandaging after treatments such as parotid gland disease, it employs a pre-action principle and a pre-set pressure bandage adjustment component. The detachable pressure bandage allows for adjustable winding, and the tightness of the bandage is quantified, enabling patients to independently adjust the pressure bandage. Neck support and positioning are achieved by positioning the chin relative to the shoulder. Simultaneously, head support and positioning are achieved through clamping and restraining on both sides of the head combined with self-adjusting airbags. Both head and neck support and positioning can be adjusted according to the patient's condition, preventing intentional or unintentional head turning that could hinder wound healing. The open support structure combined with flexible materials prevents stuffiness, provides good breathability and comfort, and the protective neck collar protects the injured area from wind and cold.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention provides a surgical head and neck postoperative auxiliary support and positioning device, comprising a spinal support plate, shoulder support frames symmetrically arranged on the upper part of the spinal support plate, and a restraint strap surrounding the lower part of the spinal support plate. The shoulder support frames are respectively connected to the restraint straps with fastening adjustment straps, and the restraint straps and fastening adjustment straps are respectively provided with adjustment buckles. The upper part of the spinal support plate is provided with a head support and fixation component and a neck fixation component. The neck fixation component is located between the shoulder support frames, and the head support and fixation component is located behind the neck fixation component. The upper part of the head support and fixation component is provided with a pressure strap adjustment component, which is located above the neck fixation component. The pressure band adjustment assembly includes a fixed post, a fixed dial, an indicator adjustment post, and a pressure bandage. The fixed post and fixed dial are symmetrically arranged on the upper part of the head support and fixation assembly. The indicator adjustment post is movably mounted on the fixed dial. The fixed post and the indicator adjustment post are horizontally arranged above the neck fixation assembly. The pressure bandage is connected between the fixed post and the indicator adjustment post. One end of the pressure bandage is sleeved on the fixed post, and the other end of the pressure bandage is snapped around the indicator adjustment post. The pressure bandage adjustment assembly, designed for situations requiring pressure bandaging after treatment of parotid gland diseases, employs a pre-action principle to allow the detachable pressure bandage to be rolled up and adjusted, achieving the technical effect of patient self-adjustment of pressure bandaging.

[0007] Furthermore, the front end face of the fixed dial is provided with a connecting groove that does not penetrate through it. The side wall of the connecting groove is provided with locking grooves evenly distributed around its circumference. The rear part of the locking groove is connected to a movable groove. The front end face of the fixed dial is provided with graduations evenly distributed around its circumference. The graduations are set around the connecting groove. The positions of the graduations and the locking grooves are set one-to-one, so that the tightness of the pressure strap is quantified by the graduations, making it easy to control the adjustment amount.

[0008] Further, the indicating adjustment column includes a rotating column, a connecting spring, movable blocks, a pointer, and a mounting block. The rotating column is movably disposed within a connecting groove. The connecting spring is fixedly disposed on one end face of the rotating column. The movable blocks are symmetrically disposed on the side wall of the rotating column near the connecting spring. The movable blocks respectively engage and slide within locking grooves. When the connecting spring is in a compressed state, the movable blocks respectively move within the movable grooves. The pointer is disposed on the side wall of the rotating column and is located in front of the fixed dial. The distance to the end face of the fixed dial is greater than the depth of the locking groove. During the process of pressing the rotating column to disengage the movable block from the locking groove, it is not affected by the pointer. The side wall of the rotating column is not provided with a through insertion groove. The insertion groove is located in front of the pointer. The insertion groove is not provided with symmetrically arranged insertion holes. The mounting block is locked in the insertion groove. The lower part of the mounting block is symmetrically provided with insertion pins. The insertion pins are inserted into the insertion holes. The upper part of the mounting block is rotatably provided with a pull plate. After one end of the pressure strap is pierced by the insertion pin, it is pressed into the insertion groove by the mounting block.

[0009] When patients need to adjust the pressure bandage according to their own situation (loosening during sleep and tightening when awake) or the swelling of the affected area (the pressure bandage gradually tightens as the swelling subsides), they can contact a doctor online or the doctor can inform the patient of the adjustment amount each time during the installation of the pressure bandage. The tightness of the pressure bandage can be adjusted by turning the pointer to different scale values. Simply press the rotating column, the connecting spring is compressed, and the movable block slides out of the locking slot into the movable slot. Twisting the rotating column can tighten or loosen the pressure bandage. At this time, the pointer points to different scales, which measure the amount of winding. When the pointer points to the desired scale, release the rotating column. Under the elastic force of the connecting spring, the movable block re-locks into the locking slot to position the length of the pressure bandage. The adjustment is convenient, time-saving and labor-saving.

[0010] Furthermore, the head support and fixation assembly includes a head support pad and a rotation limiting assembly. The head support pad is located on the upper part of the spine support plate, and the rotation limiting assembly is horizontally located on the head support pad. The head support pad includes a main support column, a support arc plate, and an airbag. The main support column is located at the upper center of the spine support plate, and the support arc plate is located on the main support column. The support arc plate is arc-shaped to fit the arc structure of the human head, providing space for the patient's head and avoiding the feeling of stuffiness caused by the covering structure. The support arc plate has a through hole to allow hair to pass through, preventing hair from piling up at the neck. The airbag is located on the inner side of the support arc plate and above the through hole. The airbag is connected to an inflation handle via an air tube. The inflation handle has a deflation valve. Inflation is performed by inflating the airbag through the inflation handle to support the patient's head and provide support for the patient. The airbag can be adjusted according to the size of the patient's head. When the head support is not needed, the airbag can be deflated through the deflation valve.

[0011] Furthermore, the rotation limiting assembly includes a mounting frame, a first limiting plate, a second limiting plate, and a limiting fixing block. The mounting frame is mounted on the outer wall of the supporting arc plate and on the upper part of the airbag cushion. The first and second limiting plates are symmetrically and movably arranged on both sides of the mounting frame. Elastic pads are respectively provided on the opposite surfaces of the first and second limiting plates. The limiting fixing block is engaged with the rear side wall of the mounting frame. By clamping and restricting the two sides of the head in combination with the self-adjusting airbag cushion, the support and positioning effect of the patient's head is achieved, preventing the patient from intentionally or unintentionally turning their head, which is detrimental to wound healing. When the patient has recovered to a certain extent and no longer needs to restrict head rotation, the first and second limiting plates can be disassembled for convenient use.

[0012] Preferably, the mounting bracket has centrally symmetrical, non-through-connecting limiting slots on both sides. A fixing slot is located at the center of the rear side wall of the mounting bracket. A connecting slot is located at the center of the fixing slot. A positioning slot is located at the bottom of the connecting slot. The limiting slot, positioning slot, connecting slot, and fixing slot are interconnected. A limiting fixing block is engaged within the fixing slot. A connecting plate is located on the side wall of the limiting fixing block. A positioning plate is located on the side wall of the connecting plate. The connecting plate slides horizontally within the connecting slot. The positioning plate slides horizontally within the positioning slot. The connecting plate, positioning plate, connecting slot, and positioning slot have the same width, allowing the positioning plate to slide only laterally within the positioning slot.

[0013] Furthermore, a first adjusting rod and a second adjusting rod are horizontally arranged on the opposite surfaces of the first and second limiting plates, respectively. The first and second adjusting rods are centrally symmetrically arranged and are slidably disposed in the limiting slots. The opposite sidewalls of the first and second adjusting rods are evenly distributed with toothed grooves. When the toothed grooves on the first and second adjusting rods are connected, the positioning insert plate engages and is inserted into the toothed grooves. The sidewalls of the toothed grooves near the limiting fixing blocks are wedge-shaped. The positioning insert plate engages and is inserted into the toothed grooves, thereby simultaneously positioning the relative positions of the first and second limiting plates. The wedge-shaped surface on the toothed grooves allows the positions of the first and second adjusting rods to be finely adjusted according to the sliding direction of the wedge-shaped inclined surface, even if the toothed grooves on the first and second adjusting rods are not completely connected. This allows the positioning insert plate to slide into the toothed grooves for positioning. The flexible elastic pad has a certain adjustment margin.

[0014] Furthermore, the neck fixation assembly includes a neck support column, a neck abutment column, a neck support plate, an adjusting slider, a chin locator, and a protective neck brace. The neck support column is mounted on the spine support plate and is located in front of the main support column. The neck abutment column is horizontally positioned above the neck support column. A clamp is rotatably mounted on the front side wall of the neck support column, and the clamp is located below the neck abutment column. The neck support plate is symmetrically mounted on the shoulder support frame. The adjusting sliders are movably mounted on opposite side walls of the neck support plate, and non-continuously distributed on the outer side walls of the adjusting sliders are respectively... The neck support plate is fixed to the neck support plate by engaging the connecting threaded holes with the connecting threaded holes using internal hex screws. The mandibular locator is horizontally installed inside the adjusting slider. The position of the mandibular locator can be adjusted up and down through the connecting threaded holes. The protective neck sleeve is located below the mandibular locator. The outer side of the protective neck sleeve is equipped with an adjusting strap. The protective neck sleeve is installed on the front side of the neck abutment post through a clamp and the adjusting strap. Ventilation holes are evenly distributed through the protective neck sleeve. The protective neck sleeve does not provide support; it only serves to protect the injured area from wind and cold.

[0015] Furthermore, the mandibular locator includes an adjusting slide rod, a pin, a positioning arc rod, and a mandibular abutment block. The adjusting slide rod is respectively fitted and slidably disposed on the opposite side wall of the adjusting slider. The adjusting slide rod is provided with evenly distributed adjusting holes. The pin passes through the adjusting holes and is engaged with the center of the opposite side wall of the adjusting slider. The positioning arc rod is connected to the front side of the adjusting slide rod. The mandibular abutment block is disposed at the center of the positioning arc rod. The edge of the mandibular abutment block is provided with a smooth surface. The position of the mandibular abutment block can be adjusted back and forth by the cooperation of the pin and the adjusting holes.

[0016] The patient rests their neck against the cervical support post, and then the position of the mandibular locator is adjusted according to the position of their mandible. The mandibular support block holds the patient's chin, and the movement of the patient's mandible is restricted through point positioning, thereby supporting and positioning the patient's neck. This ensures breathability and comfort while achieving the effect of neck support and positioning.

[0017] Preferably, the inner walls of the spine support plate and the shoulder support frame are provided with breathable cotton pads, the airbag pad and the neck abutment post are made of medical silicone, the chin abutment block is fitted with a silicone pad, the elastic pad is made of memory foam, and the protective neck brace is made of foam sponge.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows:

[0019] 1. This invention provides a surgical head and neck postoperative auxiliary support and positioning device. Based on the need for pressure bandaging after treatments such as parotid gland disease, it employs a pre-action principle and a pre-set pressure bandage adjustment component. The detachable pressure bandage can be rolled up and adjusted, with the tightness of the bandage quantified via a scale. When patients need to adjust the pressure bandage according to their own condition (loosening during sleep and tightening when awake) or the swelling of the affected area (gradually tightening as the swelling subsides), they can contact a doctor online or have the doctor inform them of the adjustment amount beforehand during bandage installation. The tightness of the pressure bandage is adjusted by turning the pointer to different scale values, achieving the technical effect of patient self-adjustment of the pressure bandage, saving time and effort.

[0020] 2. The head support and fixation component is designed to support and position the patient's head by clamping and restricting the sides of the head in conjunction with an adjustable airbag. This prevents the patient from intentionally or unintentionally turning their head, which is detrimental to wound healing. When the patient has recovered to a certain extent and no longer needs to restrict head rotation, the first and second limiting plates can be removed for convenient use.

[0021] 3. With the neck fixation component in place, the patient rests their neck against the neck support post. Then, based on the position of their mandible, the position of the mandibular locator is adjusted by adjusting the slider and the slider rod, so that the mandibular abutment block is against the patient's chin. By using point positioning, the movement of the patient's mandible is restricted, thereby supporting and positioning the patient's neck. This ensures breathability and comfort while achieving the effect of neck support and positioning. At the same time, a protective neck brace is used to protect the injured area from wind and cold.

[0022] 4. An arc-shaped support plate is set up to fit the arc structure of the human head, leaving space for the patient's head and avoiding the stuffiness caused by the covering structure.

[0023] 5. Inflate the airbag cushion with the inflation handle to support the patient's head and provide support. The airbag can be adjusted according to the size of the patient's head. When the head support is no longer needed, deflate the airbag through the deflation valve. It supports and positions the patient's head while facilitating the patient's daily life.

[0024] 6. The design of the clearance hole allows hair to pass through for patients with long hair, preventing hair from piling up on the neck and causing discomfort.

[0025] 7. This invention adopts an open support structure combined with the characteristics of flexible materials. The surfaces or points that come into contact with the patient are made of flexible materials such as medical silicone and memory foam, which have a certain degree of deformation and strong breathability, thus improving the patient's comfort.

[0043] Working principle and workflow:

[0044] In practical use, initially, the pressure straps 34, first limiting plate 222, second limiting plate 223, chin locator 46, and protective neck brace 47 are not installed. First, the invention is worn on the patient, with the shoulder support frame 11 resting on the patient's shoulders and the back support plate 1 fitting against the patient's back. The positions of the shoulder support frame 11 and back support plate 1 are fixed by adjusting the buckles 14 to tighten the restraint straps 12 and the fastening adjustment straps 13. Long-haired patients can let their hair pass through the clearance holes 213 to avoid excessive hair accumulation at the neck area causing discomfort. Subsequently, medical staff... Based on the patient's surgical condition, the personnel determine whether pressure bandaging is necessary. If not, neck and head support and fixation can be performed directly. If necessary, one end of the pressure bandage 34 is fixedly attached to the fixation post 31, and the other end is penetrated through the insertion pin 3372 and pressed into the insertion groove 335 along with the mounting block 337. The pressure bandage 34 is then placed on the patient's chin, and after being applied to the parotid gland injury area through gauze, the rotating post 331 is pressed, compressing the connecting spring 332, causing the movable block 333 to slide out of the locking groove 322 into the movable groove 323. The rotating post is then rotated. 331 retracts the pressure bandage 34. When the required pressure is reached, the rotating column 331 is released. The elasticity of the connecting spring 332 causes the movable block 333 to slide back into the locking groove 322 for positioning. Observe the scale 324 pointed to by the pointer 334 at this time. Medical staff can inform the patient in advance how long after the swelling subsides, or after the swelling subsides, to adjust the tightness of the pressure bandage 34 according to the above steps. The tightness of the pressure bandage 34 is quantified by the scale 324. When the patient is asleep, the pressure bandage 34 needs to be loosened appropriately. When the patient wakes up, it needs to be retracted. The compression bandage 34 can be tightened or loosened by consulting medical staff and instructing the pointer 334 to rotate through several scales 324. This allows the patient to independently adjust the tightness of the compression bandage 34. Even in case of emergencies during the recovery process, the patient can consult a doctor online to adjust the compression bandage 34 without having to go to the hospital to disassemble and reapply pressure bandage, saving time and effort. When the compression bandage 34 needs to be replaced, the installation block 337 can be removed by pulling the plate 3371, and then the compression bandage 34 can be removed and reinstalled following the above steps.

[0045] After adjusting the pressure bandage 34, the neck is secured so that the back of the patient's neck rests against the neck support post 42. Then, the adjustment strap 471 is opened, and the protective neck glove 47 is wrapped around the back of the patient's neck and secured with the adjustment strap 471. At the same time, the adjustment strap 471 is fixed to the neck support post 41 via the splint 43. The protective neck glove 47 keeps the patient's injured area warm and provides ventilation while protecting against wind and cold. Then, according to the position of the patient's mandible, the mandibular locator 46 is adjusted through the connecting threaded hole 451 on the adjusting slider 45. The lower position is adjusted by adjusting the adjustment hole 462 on the sliding rod 461 to adjust the front and back position of the mandibular locator 46, so that the mandibular contact block 465 abuts against the patient's chin. By point positioning, the movement of the patient's mandible is restricted, thereby supporting and positioning the patient's neck, ensuring breathability and comfort while achieving the effect of neck support and positioning. Then, the first limiting plate 222 and the second limiting plate 223 are installed, and the limiting fixing block 224 is pulled outward to make the positioning insert 2242 slide into the positioning slot 2. Within 214, the first adjusting rod 2221 and the second adjusting rod 2231 are inserted into the limiting slot 2211 respectively, and pushed towards each other according to the size of the patient's head. When the elastic pad 225 fits against both sides of the patient's head, the limiting fixing block 224 is pressed in, so that the positioning plate 2242 is inserted into the toothed groove 2222. The wedge-shaped setting on the side wall of the toothed groove 2222 ensures that even if the toothed grooves 2222 on the first adjusting rod 2221 and the second adjusting rod 2231 are not fully engaged, pushing the positioning plate 2242 will still... The positions of the first adjusting rod 2221 and the second adjusting rod 2231 can be finely adjusted according to the sliding direction of the wedge-shaped inclined plane, so that the positioning insert 2242 slides into the tooth groove 2222 for positioning. The elastic pad 225 made of memory foam material has a certain adjustment margin to complete the positioning of the patient's head and prevent the patient from intentionally or unintentionally turning their head, which is not conducive to wound healing. When the patient has recovered to a certain extent and no longer needs to restrict head rotation, the first limiting plate 222 and the second limiting plate 223 can be disassembled for convenient use.

[0046] The patient can then inflate the airbag 214 with the inflation handle 216 as needed to support the back of the patient's head and provide support. The airbag can be adjusted according to the size of the patient's head. When the head support is no longer needed, the air can be released through the deflation valve 215. This system provides head support and positioning while facilitating the patient's daily life.
