Description

Technical Field

[0001] This invention relates to the field of postoperative care equipment for neurosurgery, and in particular to a shoulder and neck support for postoperative care in neurosurgery. Background Technology

[0002] Immobilization and proper fixation of the neck and shoulders after neurosurgery are key measures to prevent fatal complications, protect surgical wounds, maintain craniocervical biomechanical stability, and promote the recovery of neurological function. These measures are applied throughout the entire process, from the acute phase in the ICU to the bedridden phase and rehabilitation after getting out of bed.

[0003] For example, Chinese invention patent No. 202411867356.5 specifically discloses a shoulder and neck support device for neurosurgical patients after surgery. It uses a shoulder clamp to support the shoulder and is fixed with straps so that the neck support can be adjusted in height on the shoulder clamp to support the chin and protect the back of the neck and head. On the basis of the fixed head support board, a headband is used to hold the forehead and a chin support is used to support the chin, thereby ensuring that the entire head is stabilized on the shoulder clamp and head support board, so as to stabilize the shoulder, neck and surrounding tissues of the neurosurgical patient after surgery.

[0004] However, the above-mentioned technical solutions still have significant safety and stability issues in actual use, as their structure is too rudimentary and their operation is extremely complex. Summary of the Invention

[0005] To address the above problems, this invention provides a shoulder and neck support for postoperative care in neurosurgery. By utilizing the cooperation of a shoulder support, a front jaw support, and a cervical posterior airbag, it immobilizes and properly fixes the patient's shoulder and neck, thereby stabilizing the patient's shoulder, neck, and surrounding tissues after neurosurgery. Furthermore, by improving the knob structure that drives the front jaw support to rise and fall, the inflation structure of the cervical posterior airbag is made more reasonable, ensuring a simple structure while simplifying the operation process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A neck and shoulder support for postoperative care in neurosurgery, comprising: Shoulder support, chin support, and cervical spine airbag; The shoulder support covers the patient's shoulder, the chin support is installed on the shoulder support, the chin support is adjustable in height relative to the shoulder support, the cervical posterior airbag is hinged to the chin support, and the cervical posterior airbag and the chin support work together to form a surrounding area around the patient's neck. The shoulder support is provided with a drive mechanism for controlling the raising and lowering of the chin rest. The drive mechanism includes a knob located on the outer wall of the shoulder support, which is rotated by a rotating shaft that extends into the shoulder support. The knob and the rotating shaft are equipped with an inflation / deflation mechanism, which inflates and deflates the posterior cervical airbag.

[0007] As an improvement, the drive mechanism further includes a driving bevel gear set, a flexible shaft, and a transmission bevel gear set; The active bevel gear set is disposed at the end of the rotating shaft that extends into the shoulder support, and the active bevel gear set drives the rotating shaft and the flexible shaft; The flexible shaft is provided in two sets, and the flexible shaft is connected to the corresponding transmission bevel gear set. The transmission bevel gear set is provided in two sets, which are respectively connected to the lifting modules on both sides of the shoulder support.

[0008] As an improvement, the lifting module is a lead screw lifting module, which includes a fixed column, a movable column, a lead screw, and a lead screw nut.

[0009] As an improvement, the inflation / deflation mechanism includes a valve core, an inflation connector, and an inflation tube; The valve core is disposed in the air passage that passes through the central axis of the rotating shaft, and the valve core controls the opening and closing of the air passage; The inflation connector is arranged in a ring shape. The inflation connector is rotated and sealed with the rotating shaft. The inflation connector is connected to the air passage through a connection hole opened on the side wall of the rotating shaft. The inflation tube connects the inflation connector to the cervical posterior airbag.

[0010] As an improvement, a cushioning airbag is provided on the shoulder support corresponding to the patient's chest area, and a lifting airbag is provided on the front jaw support corresponding to the patient's lower jaw area. Both the cushioning airbag and the lifting airbag are inflated by the inflation and deflation mechanism.

[0011] As an improvement, a connecting hole is also provided on the side wall of the rotating shaft to communicate with the buffer airbag and the lifting airbag. A second set of inflatable connectors is rotatably sealed at the connecting hole, and the inflatable connectors are connected to the buffer airbag and the lifting airbag through corresponding inflatable tubes.

[0012] As an improvement, the inflation / deflation mechanism further includes an inflation switching component, which switches the connection between the connecting hole and the communicating hole. The inflation switching assembly includes a guide tube, a floating inner tube, a spring component, and guide balls; The guide tube is coaxially inserted into the air passage, and a wavy guide groove is formed on the side wall of the guide tube. The floating inner tube is inserted into the guide tube. The open end of the floating inner tube is embedded in the valve core, and the sealed end of the floating inner tube extends into the air passage. The side wall of the floating inner tube is provided with an circumferential groove corresponding to the guide groove, and the side wall of the floating inner tube is also provided with a first through hole, a second through hole, a third through hole and a fourth through hole arranged sequentially along the axial direction. The spring is installed at the bottom of the air passage, and the spring elastically supports the floating inner tube; The guide ball is installed between the guide groove and the circumferential groove.

[0013] As an improvement, the side wall of the floating inner tube is provided with a groove parallel to the axial direction, and the inner side wall of the air passage has a protruding strip that engages with the groove.

[0014] As an improvement, the guide groove includes a first step, a second step, and a third step arranged in a staggered manner from high to low; When the guide ball is located on the first step, the first through hole and the connecting hole are connected. When the guide ball is located in the second step, the second through hole and the connecting hole are connected. When the guide ball is located on the third step, the third through hole connects with the connecting hole, and simultaneously, the fourth through hole connects with the connecting hole.

[0015] As an improvement, the valve core is connected to an external air supply pump via a connecting handle.

[0016] The beneficial effects of this invention are as follows: (1) The integrated head, neck and shoulder support of the present invention clamps the shoulder, the front jaw support supports the lower jaw, and the cervical spine airbag wraps the back of the neck. The three work together to form a neck ring area, realizing the three-dimensional coaxial fixation of the head, neck and shoulders. It perfectly meets the nursing requirements of prohibiting the individual turning of the head, twisting the neck and shrugging the shoulders after neurosurgery, and effectively avoids neck twisting and traction on the surgical incision, inducing intracranial rebleeding, cerebrospinal fluid leakage, and brainstem traction and compression. (2) The corrugated telescopic sleeve flexible linkage shoulder support and the front jaw support of the present invention are connected in one piece by the corrugated telescopic sleeve, which not only ensures the integrity of the structure, but also allows for compression / stretching to achieve fine adjustment of the front jaw support, adapting to patients of different heights and neck lengths. There is no rigid structural jamming, and it fits the physiological curve of the human neck. The cervical spine airbag is hinged to the front jaw support, which can adapt to the thickness of the patient's neck and the physiological curvature of the cervical spine, wrapping around without dead angles. At the same time, it works with the shoulder support to clamp the shoulder, restricting the shoulder from raising and shaking, and eliminating abnormal neck and shoulder linkage from the source. (3) The present invention integrates the drive and inflation / deflation of the airbag by means of a knob. The outer knob simultaneously serves as the height adjustment drive and the airbag inflation / deflation control, eliminating the need for separate operation. It is easy for nursing staff to operate and is suitable for quick wearing and adjustment at the bedside in the ward. (4) This invention uses a combination of multiple airbags, including a cervical spine airbag, a chest cushioning airbag, and a chin support airbag, to overcome the defects of traditional rigid neck braces that cause pressure. The airbags on the back of the neck, chin, and chest are flexible and fit together to disperse local pressure and prevent pressure sores caused by long-term wear. It is especially suitable for patients who have been bedridden for a long time after neurosurgery, have reduced sensation, or have been bedridden for a long time. The cushioning airbag is set on the patient's chest to limit the forward tilting and twisting of the trunk, maintain the coaxial position of the head, neck, shoulders, and trunk, and prevent the obstruction of jugular venous return and the increase of intracranial pressure caused by looking down and hunching the chest. The cervical spine airbag, the support airbag, and the cushioning airbag share the same internal airway and inflation connector on the rotating shaft, so there is no need to configure multiple sets of inflation tubing separately. The structure is simple and the tubing is neat, reducing the risk of nursing entanglement. (5) The present invention uses a guide tube + floating inner tube + spring component + guide ball + multi-step guide groove to achieve the switching of inflation mode by rotating the knob, three-level precise control, and supply of air as needed. In the first stage, only the cervical spine airbag is inflated, which is suitable for simple neck fixation. In the second stage, only the jaw + chest airbag is inflated, which is suitable for supporting and decompressing. In the third stage, all airbags are connected at the same time to achieve dynamic connection and adjustment of all airbags.

[0017] In summary, this invention has the advantages of simple structure, simplified operation, and safety and reliability, and is especially suitable for the field of postoperative care technology for neurosurgical patients. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Example 1: like Figures 1-4 As shown, a neck and shoulder support for postoperative care in neurosurgery includes: The shoulder support 1, the chin support 2, and the posterior cervical airbag 3 are provided. The shoulder support 1 and the chin support 2 are made of rigid materials. The connection structure between the posterior cervical airbag 3 and the chin support 2 refers to the connection structure in the utility model patent application No. 202021544144.0, as detailed in the appendix to that patent specification. Figures 5-7 ; The shoulder support 1 covers the patient's shoulder, the front jaw support 2 is installed on the shoulder support 1, the front jaw support 2 is adjustable in height relative to the shoulder support 1, the cervical posterior airbag 3 is hinged to the front jaw support 2, and the cervical posterior airbag 3 and the front jaw support 2 cooperate to form a surrounding area 100 around the patient's neck. The shoulder support 1 is provided with a drive mechanism 5 for controlling the lifting and lowering of the front jaw support 2. The drive mechanism 5 includes a knob 51 disposed on the outer side wall of the shoulder support 1. The knob 51 is rotatably disposed by a rotating shaft 52 extending into the shoulder support 1. The knob 51 and the rotating shaft 52 are provided with an inflation / deflation mechanism 6, which inflates and deflates the cervical posterior airbag 3.

[0024] It should be noted that in this invention, the shoulder support 1 rests against the patient's chest, covering the patient's shoulders so that the cervical spine support is supported on the patient's shoulders. At the same time, the front jaw support 2 rests against the patient's lower jaw, while the posterior cervical airbag 3 rests against the back of the patient's neck. Through the cooperation of the front jaw support 2 and the posterior cervical airbag 3, the patient's cervical spine is restrained and fixed, strictly maintaining the neutral position of the head and neck. This perfectly meets the nursing requirements after neurosurgery, which prohibits turning the head, twisting the neck, or shrugging the shoulders alone. It effectively avoids neck twisting and traction on the surgical incision, inducing intracranial rebleeding, cerebrospinal fluid leakage, and brainstem traction and compression.

[0025] Furthermore, the lifting structure of the existing cervical spine support's front jaw support 2 is too complicated. For example, in the invention patent with patent application number 202411867356.5, the lifting structure of the front jaw support is located on the back, and it requires the cooperation of others to operate, making the operation very cumbersome.

[0026] The lifting structure of the front jaw support 2 in this invention adopts a pre-conditioning mechanism. The specific structure is similar to that in the utility model patent with patent application number 202021544144.0. That is, the driving mechanism 5 in this invention also includes an active bevel gear set 53, a flexible shaft 54 ​​and a transmission bevel gear set 55. The active bevel gear set 53 is disposed at the end of the rotating shaft 52 that extends into the shoulder support 1, and the active bevel gear set 53 drives the rotating shaft 52 and the flexible shaft 54. The flexible shaft 54 ​​is provided in two sets, and the flexible shaft 54 ​​is connected to the corresponding transmission bevel gear set 55. The transmission bevel gear set 55 is provided in two sets, and the transmission bevel gear set 55 is respectively connected to the lifting module 11 on both sides of the shoulder support 1.

[0027] Furthermore, the lifting module 11 is a lead screw lifting module, which includes a fixed column, a movable column, a lead screw, and a lead screw nut (the specific structural structure is not shown in the diagram; for details, refer to the structure in the utility model patent with patent application number 202021544144.0, see the appendix to the patent specification). Figure 4 The top of the movable column is rotatably connected to the two ends of the front jaw support via a pivot.

[0028] The specific adjustment process is as follows: Knob 51 drives the rotating shaft 52 to rotate, which in turn drives the active bevel gear 531 in the active bevel gear set 53 mounted on the rotating shaft 52 to rotate. The rotation of the active bevel gear 531 drives the two driven bevel gears 532 in the active bevel gear set 53 to rotate. The rotation of the driven bevel gears 532 is transmitted through the corresponding flexible shaft 54, causing the bevel gear in the transmission bevel gear set 55 that is connected to the flexible shaft 54 ​​to rotate. The other bevel gear in the transmission bevel gear set 55 is mounted on the corresponding lead screw. Through the transmission of the transmission bevel gear set 55, the lead screw rotates (the lead screw is rotated and mounted on the fixed column). During the rotation of the lead screw, since the screw nut with threaded engagement is fixed on the movable column, the movable column moves and adjusts along the axial direction of the lead screw, thereby causing the movable column to move up and down, driving the front jaw support 2 to move up and down.

[0029] Furthermore, the threaded engagement structure of the lead screw and lead screw nut has a self-locking function, which enables the lifting and lowering of the front jaw support 2 to have the function of stopping and locking immediately.

[0030] Therefore, when using the cervical spine support for post-neurosurgery care of the present invention, patients can adjust it themselves by turning the knob without the need for assistance from others, fully considering the patient's own user experience.

[0031] In addition, in order to ensure convenient operation of inflating and deflating the cervical posterior airbag 3 and prevent the inflation tube from moving around randomly, the inflation and deflation mechanism 6 includes a valve core 61, an inflation connector 62 and an inflation tube 63. The valve core 61 is disposed in the air passage 521 that passes through the central axis of the rotating shaft 52, and the valve core 61 controls the opening and closing of the air passage 521. The inflation connector 62 is arranged in a ring shape. The inflation connector 62 is rotatably and sealingly fitted with the rotating shaft 52. The inflation connector 62 is connected to the air passage 521 through the connection hole 522 opened on the side wall of the rotating shaft 52. The inflation tube 63 is connected to the inflation connector 62 and the cervical posterior airbag 3.

[0032] In this invention, the inflation / deflation mechanism 6 is integrated into the knob 51, and the hollow channel inside the rotating shaft 52 is used as the air passage 521. After the valve core 61 is opened, the pumped air enters the inflation connector 62 through the air passage 521 and the connection hole 522, and then enters the cervical spine airbag 3 through the inflation tube 63.

[0033] It should be noted that the inflatable connector 62 and the rotating shaft 52 are in a rotating sealed fit. A rubber sealing ring is provided at the sealing fit position to prevent leakage at the rotating fit position. The shaft sealing of the rubber sealing ring is a common sealing technology in the field, so it will not be described in detail here.

[0034] Example 2: Referring to Example 1, the difference between Example 2 and Example 1 lies in the following: like Figure 2 , Figures 5-13 As shown, a cushioning airbag 12 is provided on the shoulder support 1 at the location corresponding to the patient's chest, and a lifting airbag 21 is provided on the front jaw support 2 at the location corresponding to the patient's lower jaw. Both the cushioning airbag 12 and the lifting airbag 21 are inflated by the inflation and deflation mechanism 6.

[0035] Furthermore, a connecting hole 523 is provided on the side wall of the rotating shaft 52, which communicates with the buffer airbag 12 and the lifting airbag 21. A second set of inflatable connectors 62 are rotatably sealed at the connecting hole 523. The inflatable connectors 62 are connected to the buffer airbag 12 and the lifting airbag 21 through the corresponding inflatable tubes 63.

[0036] It should be noted that the shoulder support 1 is positioned at the patient's chest, flexibly conforming to the chest, restricting forward tilting and lateral twisting of the torso, maintaining a neutral position with the head, neck, shoulders, and torso aligned on the same axis, while also cushioning pressure and preventing pressure sores; the front jaw support 2 is positioned at the contact point with the patient's chin, replacing a rigid support, flexibly supporting the chin, dispersing local pressure, improving comfort, and providing multi-point flexible support extending from the neck to the chin and chest, avoiding the local compression, redness, and pressure sores caused by traditional rigid supports, making it suitable for long-term bedridden patients after neurosurgery.

[0037] Furthermore, the inflation / deflation mechanism 6 also includes an inflation switching component, which switches the connection between the connecting hole 522 and the communicating hole 523. The inflation switching assembly includes a guide tube 64, a floating inner tube 65, a spring 66, and a guide ball 67. The guide tube 64 is coaxially inserted into the air passage 521, and a wavy guide groove 641 is provided on the side wall of the guide tube 64. The floating inner tube 65 passes through the guide tube 64. The open end of the floating inner tube 65 is embedded in the valve core 61, and the sealed end of the floating inner tube 65 extends into the air passage 521. The side wall of the floating inner tube 65 is provided with an circumferential groove 651 corresponding to the guide groove 641. The side wall of the floating inner tube 65 is also provided with a first through hole 652, a second through hole 653, a third through hole 654 and a fourth through hole 655 arranged sequentially along the axial direction. The floating inner tube 65 is stepped, so that when the floating inner tube 65 is raised or lowered, the step 650 on the floating inner tube 65 can abut against the lower edge of the guide tube 64 for limiting. The spring member 66 is installed at the bottom of the air passage 521, and the spring member 66 elastically supports the floating inner tube 65; The guide ball 67 is installed between the guide groove 641 and the circumferential groove 651.

[0038] Specifically, the guide groove 641 includes a first step 642, a second step 643, and a third step 634 arranged in a staggered manner from high to low; When the guide ball 67 is located at the first step 642, the first through hole 652 is connected to the connecting hole 522. When the guide ball 67 is located in the second step 643, the second through hole 653 is connected to the connecting hole 523. When the guide ball 67 is located at the third step 634, the third through hole 654 is connected to the connecting hole 522, and simultaneously, the fourth through hole 655 is connected to the connecting hole 523.

[0039] It should be noted that after the cervical posterior airbag 3 is inflated, it acts on the patient's cervical spine to restrict and fix the cervical spine. The function of the buffer airbag 12 and the lifting airbag 21 is to provide gentle support. Therefore, the inflation pressure of the cervical posterior airbag 3 is different from that of the buffer airbag 12 and the lifting airbag 21. When the buffer airbag 12 and the lifting airbag 21 are inflated, they cannot be inflated synchronously with the cervical posterior airbag 3. Therefore, the inflation path of the cervical posterior airbag 3, the buffer airbag 12 and the lifting airbag 21 can be switched through the inflation switching component.

[0040] Specifically, when the guide ball 67 is located at the first step 642, the first through hole 652 is connected to the connecting hole 522. At this time, the air input by the valve core 61 only enters the cervical posterior airbag 3 for inflation. After the inflated cervical posterior airbag 3 cooperates with the raised and lowered front jaw support 2 to clamp the patient's neck, the system is switched so that the guide ball 67 is located at the second step 643. At this time, the second through hole 653 is connected to the connecting hole 523. The air input by the valve core 61 enters the buffer airbag 12 and the lifting airbag 21 respectively, causing the buffer airbag 12 and the lifting airbag 21 to expand and form a buffer and lift for the patient's jaw and chest.

[0041] The gas path switching process is explained in detail below: Initially, the guide ball 67 is positioned at the first step 642. Since half of the guide ball 67's volume is engaged in the guide groove 641 and the other half in the annular groove 651, the spring 66 provides elastic floating support to the floating inner tube 65 as it is compressed. The floating inner tube 65 carries the ball 67 within the guide groove 641. The ball 67 moves from the first step 642 to the second step 643, where it is again limited by the crest at the second step 643, thus defining the movement distance of the floating inner tube 65. This achieves the switching from the first through hole 652 to the second through hole 653. Similarly, when the guide ball 67 is located at the third step 644, the third through hole 654 connects with the connecting hole 522, and simultaneously, the fourth through hole 655 connects with the connecting hole 523. This achieves three levels of gas flow switching. Following the above switching process, switching again will reset the system to its initial state.

[0042] Furthermore, in the third position, when the guide ball 67 is located at the third step 644, the third through hole 654 connects with the connecting hole 522. Simultaneously, the fourth through hole 655 connects with the connecting hole 523. This is to allow for the rapid release of gas from the cervical posterior airbag 3, buffer airbag 12, and lifting airbag 21 during the removal of the cervical spine support for post-neurosurgical care, thus quickly removing the cervical spine support. On the other hand, to adapt to the different fixation and support requirements during the acute, recovery, and rehabilitation phases after surgery, the cervical posterior airbag 3, buffer airbag 12, and lifting airbag 21 can be connected, allowing gas to circulate among them. This achieves dynamic balance among the three sets of airbags, realizing a rigid-flexible combination of full-coverage fixation of the head, neck, and shoulders, suitable for strict immobilization during the acute phase after neurosurgical surgery, and exhibiting strong clinical adaptability.

[0043] Example 3: Referring to Example 2, the difference between Example 3 and Example 2 lies in the following: like Figure 6 , Figure 8 As shown, the floating inner tube 65 has a groove 656 parallel to the axial direction on its side wall, and the air passage 521 has a protruding strip 524 that engages with the groove 656 on its inner side wall.

[0044] It should be noted that, in order to ensure that the internal inflation / deflation mechanism 6 and inflation switching component rotate synchronously when the knob 51 drives the rotating shaft 52 to rotate, and to prevent misalignment, the cooperation between the slot 656 and the protrusion 524 allows the floating inner tube 65 to rotate synchronously with the rotating shaft 52, thereby ensuring the correspondence of the connecting hole 522, the connecting hole 523, the first through hole 652, the second through hole 653, the third through hole 654, and the fourth through hole 655.

[0045] Example 4: Referring to Example 2, the difference between Example 3 and Example 2 lies in the following: like Figure 7 , Figure 14 As shown, the valve core 61 is connected to an external air supply pump via a connecting handle 7.

[0046] In addition, to ensure the ease of operation of the floating inner tube 65 and the stability of the valve core 61 connection, the present invention is also equipped with a connecting handle 7. The connecting handle 7 is provided with a thread corresponding to the valve core 61. By rotating the thread, the connecting handle 7 and the valve core 61 are connected. A limiting crossbar 71 is provided inside the connecting handle 7. When the limiting crossbar 71 touches the valve core 611 on the valve core 61, the valve core 61 opens, and gas is input or output from the valve core 61. The other end of the connecting handle 7 is connected to a gas pump. When gas is discharged, the other end of the connecting handle 7 is not connected to the gas pump to facilitate the rapid discharge of gas.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
