Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a head, neck and shoulder integrated positioning pad for surgery. Background Art

[0002] Currently, patient positioning is a crucial step in the preparation for anterior cervical spine surgery. However, the way this step is performed varies widely and is not standardized. Most medical institutions rely on the surgical team to temporarily adjust the patient's position at the treatment site by manually folding drapes or using auxiliary tools such as head immobilizers. This method is not only time-consuming and labor-intensive, but also makes it difficult to ensure precise and consistent results with each operation. It also makes it difficult for the patient's cervical spine to maintain an ideal physiological curvature during surgery. This suboptimal positioning not only increases the difficulty of the surgical operation and affects the surgeon's field of view and surgical precision, but can also exacerbate discomfort during or after the operation due to the lack of proper support for the cervical spine, potentially increasing surgical risks such as the risk of complications such as nerve damage and vascular compression.

[0039] like Figure 1 As shown, the embodiment of the present application provides a head, neck and shoulder integrated body positioning pad for surgery, comprising a body positioning pad body 100. During use, the patient lies supinely on the body positioning pad body 100.

[0040] like Figure 1 and Figure 2As shown, the positioning cushion body 100 is a cover made of a smooth, flexible material and has a flexible filling inside, which can promote blood circulation and prevent pressure sores. Exemplary fillings include, but are not limited to, memory foam, silicone blocks, cotton woven blocks, thermoplastic elastomers, latex, fibers, down, or hollow fibers. Exemplary flexible materials for the cover of the positioning cushion body 100 include, but are not limited to, pure cotton, linen, polar fleece, or non-woven fabrics.

[0041] Illustratively, the cover of the positioning cushion is made of a smooth, flexible material to facilitate post-operative cleaning and disinfection.

[0042] The body positioning pad main body 100 includes a head pad 110 , a neck pad 120 and a shoulder pad 130 .

[0043] like Figure 1 As shown, the head pad 110 is an annular structure with a through hole in the annular structure. During use, the patient lies supinely on the position pad main body 100 with the patient's head placed at the through hole. The end surface of the through hole on the head pad 110 is used to limit the patient's head to prevent displacement of the patient's head during surgery.

[0044] like Figure 1 As shown, the neck pad 120 is connected to the head pad 110; exemplarily, the connection between the neck pad 120 and the head pad 110 includes a fixed connection or a movable connection; exemplarily, the neck pad 120 and the head pad 110 are connected by knitting stitching, gluing, integral molding or snap-on connection.

[0045] During use, the patient lies supine on the position pad body 100 , with the patient's neck in contact with the neck pad 120 . The neck pad 120 supports the patient's cervical spine, helps maintain the natural curvature of the neck, reduces cervical spine pressure, and improves overall comfort.

[0046] like Figure 1 As shown, the shoulder pad 130 is coupled to the neck pad 120 , with the neck pad 120 positioned between the head pad 110 and the shoulder pad 130 .

[0047] Exemplarily, the connection between the shoulder pad 130 and the neck pad 120 includes a fixed connection or a movable connection; exemplary, the shoulder pad 130 and the neck pad 120 are connected by knitting, sewing, gluing, integral molding or snap-fitting.

[0048] During use, the patient lies supinely on the body cushion body 100 , and the shoulder pad 130 is used to support the patient's shoulders, thereby reducing shoulder discomfort caused by lying supinely for a long time.

[0049] In the medical and rehabilitation fields, correct body positioning is crucial for effective treatment. This positioning cushion, with its precise support design, helps patients maintain the correct body position during treatment, thereby improving treatment outcomes. For example, during the post-operative recovery phase, correct body positioning can accelerate wound healing and reduce complications.

[0050] like Figure 2 As shown, in one embodiment, a filling replacement channel connected to the outside world is provided on the side of the surgical head, neck and shoulder integrated positioning cushion away from the patient, and a snap assembly 400 is provided at the filling replacement channel to open or close the filling replacement channel.

[0051] During use, when more filler needs to be added to the positioning pad body 100, the snap assembly 400 is opened to open the filler replacement channel, and the external filler is stuffed into the head pad 110, neck pad 120 or shoulder pad 130 of the positioning pad body 100 through the channel, and then the filler replacement channel is closed by the snap assembly 400 to prevent the filler from slipping out of the channel.

[0052] Exemplarily, the buckle assembly 400 includes but is not limited to: a zipper, Velcro (ie, hook and loop fasteners), snap fasteners (ie, snap fasteners), or magnetic fasteners, etc.

[0053] like Figure 1 As shown, in one embodiment, the thickness of the neck pad 120 is greater than that of the head pad 110 , which helps the neck pad 120 support the patient's neck to present a natural curvature.

[0054] like Figure 1 As shown, in one embodiment, the thickness of the middle portion of the shoulder pad 130 is greater than the thickness of the surrounding area of ​​the neck pad 120, so that the shoulder blade areas on both sides of the patient are slightly concave, which better conforms to the curve of the back and shoulders of the human body and avoids the formation of pressure sores.

[0055] like Figure 3 and Figure 4 As shown, in one embodiment, the surgical head, neck and shoulder integrated body support cushion further includes a support frame 200 and a telescopic component 210 .

[0056] like Figure 3 and Figure 4 As shown, the support frame 200 is located within the head pad 110, neck pad 120, and shoulder pad 130. The support frame 200 provides a mounting base for the telescopic assembly 210 and is securely connected to the sleeve of the body cushion body 100 via bolts, snaps, adhesive bonding, or stitching. For example, the support frame 200 can be made of metal, rigid plastic, or the like.

[0057] The telescopic component 210 is capable of telescoping. Multiple telescopic components 210 are arranged on the support frame 200. At least one telescopic component 210 is distributed inside the head pad 110, at least one telescopic component 210 is distributed inside the neck pad 120, and at least one telescopic component 210 is distributed inside the shoulder pad 130.

[0058] During use, the extension of the telescopic component 210 can increase the thickness of the positioning cushion main body 100, and the shortening of the telescopic component 210 can reduce the thickness of the positioning cushion main body 100, thereby adjusting the thickness of the positioning cushion main body 100 by adjusting the length of the telescopic component 210; by adjusting the telescopic length of different telescopic components 210, the thickness of the head pad 110, the neck pad 120 or the shoulder pad 130 can be adjusted, so that the positioning cushion main body 100 can adapt to patients of different body shapes.

[0059] Exemplarily, the telescopic assembly 210 includes but is not limited to a pneumatic rod, a hydraulic rod, an electric push rod, etc. In some embodiments, the telescopic assembly 210 is a pneumatic rod.

[0060] Exemplarily, four telescopic components 210 are provided inside the head pad 110. In other embodiments, five telescopic components 210 are provided. In other embodiments, as shown in FIG. Figure 3 As shown, eight telescopic assemblies 210 are provided inside the headrest 110 .

[0061] Exemplarily, four telescopic components 210 are provided in the neck cushion 120. In other embodiments, six telescopic components 210 are provided in the neck cushion 120. In other embodiments, as shown in FIG. Figure 3 As shown, nine telescopic assemblies 210 are provided within the neck cushion 120 .

[0062] Exemplarily, five telescopic components 210 are provided in the shoulder pad 130. In other embodiments, ten telescopic components 210 are provided in the shoulder pad 130. In other embodiments, as shown in FIG. Figure 3 As shown, sixteen telescopic assemblies 210 are provided within the shoulder pad 130 .

[0063] like Figure 4 As shown, in one embodiment, the head, neck and shoulder integrated body support for surgery further includes a drive assembly 300 .

[0064] The driving assembly 300 can drive different telescopic assemblies 210 to extend and retract respectively. The driving assembly 300 includes a fluid pump 310 and a conversion unit 320 .

[0065] The fluid pump 310 can drive fluid into the telescopic component 210 to extend the telescopic component 210. Exemplarily, the telescopic component 210 is a pneumatic rod, the fluid medium is air, and the fluid pump 310 is an air pump. The air pump pumps external air into the pneumatic rod to extend and retract the pneumatic rod, and the air inlet of the air pump is provided with an air filter. In some embodiments, the air pump is provided with a built-in battery or can be connected to an external power supply. However, in other embodiments, the telescopic component 210 is a hydraulic rod, the fluid medium is liquid, and the fluid pump 310 is a hydraulic pump. It should be understood that the scope of this application is not limited to this.

[0066] like Figure 4 As shown, the fluid inlet of the conversion unit 320 is directly or indirectly connected to the fluid pump 310 through a pipe 330 or the like, and the fluid outlet of the conversion unit 320 is connected to the telescopic assembly 210. The fluid pump 310 pumps the fluid into the telescopic assembly 210 through the conversion unit 320. The number of fluid outlets of the conversion unit 320 matches the set number of the telescopic assembly 210, that is, the set number of the telescopic assembly 210 corresponds to the set number of fluid outlets of the conversion unit 320 one by one, and one fluid outlet is connected to one telescopic assembly 210. During use, the fluid pump 310 first pumps the fluid into the conversion unit 320, and the conversion unit 320 can pass the fluid into all or part of the telescopic assembly 210, thereby controlling the telescopic action of all or part of the telescopic assembly 210, and achieving the effect of finely and accurately controlling the telescopic action of the telescopic assembly 210.

[0067] For example, if the thickness of the neck pad 120 needs to be increased, the fluid pumped by the fluid pump 310 is introduced into the telescopic component 210 located in the neck pad 120 through the conversion unit 320, so that the telescopic component 210 in the neck pad 120 is stretched, and the thickness of the neck pad 120 is increased, while the thickness of the telescopic component 210 inside the head pad 110 and the shoulder pad 130 remains unchanged. When the thickness of the head pad 110 or the shoulder pad 130 needs to be increased, the same applies. For another example, when the thickness of the head pad 110, the neck pad 120 and the shoulder pad 130 needs to be increased, the conversion unit 320 can successively introduce the fluid into the head pad 110. 0, the neck pad 120 and the shoulder pad 130 inside the telescopic components 210 (of course, other orders are also possible, for example, the fluid is introduced into the shoulder pad 130, the neck pad 120 or the telescopic components 210 inside the head pad 110 in sequence), so that all the telescopic components 210 are extended, thereby increasing the thickness of the head pad 110, the neck pad 120 and the shoulder pad 130. Of course, the conversion unit 320 can also introduce the fluid into the telescopic components 210 inside the head pad 110, the neck pad 120 and the shoulder pad 130 at the same time, so that the thickness of the head pad 110, the neck pad 120 and the shoulder pad 130 are increased at the same time.

[0068] In some embodiments, the conversion unit 320 can sequentially introduce the fluid into different telescopic assemblies 210 .

[0069] like Figure 5 and Figure 6 As shown, in one embodiment, the conversion unit 320 includes a first block 322 and a second block 324 .

[0070] like Figure 8 and Figure 9 As shown, a first flow channel 326 is provided on the first block 322 , and an inlet of the first flow channel 326 is connected to the fluid pump 310 , and the fluid pump 310 can pump fluid into the first flow channel 326 .

[0071] like Figure 6 As shown, the first block 322 is mounted on the second block 324, and the first block 322 can rotate or slide relative to the second block 324. Figure 7 As shown, a second flow channel 328 is provided on the second block 324, and the inlet of the second flow channel 328 is connected to the outlet of the first flow channel 326, so that the fluid in the first flow channel 326 can be introduced into the second flow channel 328; the outlet of the second flow channel 328 is connected to the telescopic component 210, so that the fluid in the second flow channel 328 can be introduced into the telescopic component 210, causing the telescopic component 210 to extend; the outlet of the second flow channel 328 is the fluid outlet of the conversion unit 320.

[0072] Exemplarily, the plurality of telescopic assemblies 210 can be divided into a plurality of groups, for example, Figure 4As shown, the telescopic components 210 in the head pad 110 are connected in series into a group, designated as the first group. When fluid is introduced into one of the telescopic components 210 in the first group, the fluid can flow into the other telescopic components 210 in the first group. For example, the telescopic components 210 in the neck pad 120 are divided into two groups, namely the second and third groups. The telescopic components 210 on one side of the shoulder pad 130 are divided into the fourth group, the telescopic components 210 on the other side of the shoulder pad 130 are divided into the fifth group, the telescopic components 210 in the middle of the neck pad 120 are divided into the sixth group, and the telescopic components 210 in the middle of the shoulder pad 130 are divided into the seventh group. Therefore, seven second flow channels 328 are provided, and the second flow channels 328 are connected to the telescopic components 210 in each group via pipes 330. The first flow channel 326 communicates with different second flow channels 328, allowing fluid to be introduced into different groups of telescoping assemblies 210. For example, if the first flow channel 326 is connected to the second flow channel 328 corresponding to the first group of telescoping assemblies 210, the fluid pump 310 can sequentially introduce fluid into the first flow channel 326, the second flow channel 328, and the first group of telescoping assemblies 210, causing the first group of telescoping assemblies 210 to extend, thereby increasing the thickness of the head pad 110. Alternatively, the first flow channel 326 can be connected to the second flow channel 328 corresponding to the fourth group of telescoping assemblies 210, allowing one side of the shoulder pad 130 to be thicker than the other, thereby adapting to different conditions.

[0073] Of course, different telescoping components 210 may also be grouped and connected in series in other ways, which will not be described in detail here.

[0074] For example, Figure 9 As shown, the first block 322 is a cylindrical block structure. Figure 6 As shown, the second block 324 is a sleeve-like structure with an open end, and the first block 322 is rotatably mounted on the opening of the second block 324. The first block 322 rotates on the second block 324, allowing the outlet of the first flow channel 326 to communicate with the inlet of different second flow channels 328. This allows the fluid pump 310 to pump fluid into different second flow channels 328 and the corresponding telescopic assemblies 210 of the second flow channels 328, so that the drive assembly 300 can drive the different telescopic assemblies 210 to extend and retract respectively.

[0075] For example, Figure 6As shown, a rotating through hole 350 is provided on the second block 324, and a rotating shaft 360 is fixedly provided on the first block 322. The rotating shaft 360 is rotatably installed in the rotating through hole 350, so that the first block 322 is rotatably installed on the second block 324; illustratively, an external thread is provided on the rotating shaft 360, and a threaded sleeve 370 is sleeved on the rotating shaft 360. The threaded sleeve 370 is threadedly matched with the rotating shaft 360. Rotating the threaded sleeve 370 can make the first block 322 and the second block 324 approach each other, reduce the gap between the outlet of the first flow channel 326 and the inlet of the second flow channel 328, and improve the sealing performance.

[0076] For example, in some embodiments, the first block 322 is provided with a scale corresponding to the outlet of the first flow channel 326, and the second block 324 is provided with a scale corresponding to the inlet of the second flow channel 328. The first block 322 is rotated so that the scale on the first block 322 corresponds to a different scale on the second block 324, thereby facilitating the connection between the first flow channel 326 and different second flow channels 328.

[0077] In one embodiment, a one-way valve is disposed between the outlet of the second flow channel 328 and the telescoping assembly 210. The one-way valve restricts fluid flow from the telescoping assembly 210 to the second block 324. Exemplarily, the one-way valve is disposed on the second block 324 at the outlet of the second flow channel 328. In another embodiment, the one-way valve is disposed on the conduit 330 between the second flow channel 328 and the telescoping assembly 210. In other embodiments, the one-way valve is disposed at the fluid inlet of the telescoping assembly 210.

[0078] In one embodiment, a fluid discharge valve is provided on the telescopic component 210, through which the fluid in the telescopic component 210 can be discharged to the outside, thereby shortening the telescopic component 210 and reducing the thickness of the corresponding part of the positioning cushion body 100.

[0079] like Figure 6 and Figure 7 As shown, in one embodiment, a sealing gasket 340 is provided between the first block 322 and the second block 324 to ensure a sealed fit between the first flow channel 326 and the second flow channel 328. Exemplarily, two sealing gaskets 340 are provided, and multiple second flow channels 328 are provided and distributed along the circumference. Of the two sealing rings, one has a larger diameter than the other. The two sealing rings are coaxially provided on the second block 324, and the inlet of the second flow channel 328 is located between the two sealing rings.

[0080] like Figure 3 As shown, in one embodiment, the telescopic components 210 located in the head pad 110 are distributed along a first track 510 , and the first track 510 is circular.

[0081] like Figure 3As shown, in one embodiment, the telescopic components 210 located in the neck cushion 120 are distributed along a second track 520, which is arranged along a straight line. In some embodiments, the telescopic components 210 located on the second track 520 can be divided into two groups, one group of telescopic components 210 located on one side of the neck cushion 120, and the other group of telescopic components 210 located on the other side of the neck cushion 120.

[0082] like Figure 3 As shown, in one embodiment, the telescopic assembly 210 located in the shoulder pad 130 is distributed along a third track 530 and a fourth track 540, the third track 530 and the fourth track 540 are arranged along a straight line, and there is an angle α between the third track 530 and the fourth track 540, where 0°≤α≤90°.
