[0002] The surgical position pad is a medical device used on the operating table in the operating room. It can not only effectively relieve the local pressure sores caused by the long operation time, but also use different position pads according to the different surgical positions and patient parts, so as to stretch the patient's limbs and diseased parts, and facilitate the doctor to perform surgical operations. The design and selection of specific surgical positions are important factors affecting the success of an operation. It is especially important for posterior cervical and lumbar spine surgery, because after general anesthesia, the patient's muscles relax, and the whole body or part loses autonomy and active muscle defense function. A good surgical position pad can not only help to fully expose the surgical field and facilitate the smooth operation, but also should not interfere with the patient's normal breathing and circulation functions, especially to avoid improper posture leading to iatrogenic compression injury of the cervical spinal cord, which can lead to serious complications such as postoperative paralysis of patients.

[0003] In the prior art, existing positioning cushions are usually fixed in shape, and corresponding positioning cushions need to be replaced according to patients of different body shapes. When anesthetized patients are transferred to a positioning cushion that has been placed, a suitable positioning cushion needs to be selected in order to stretch the patient's limbs and affected parts. When the patient lies on the pre-placed positioning cushion, the patient may be in an inappropriate state, and the patient needs to be lifted up and the positioning cushion needs to be rearranged. However, the positioning cushions for the patient's head, neck, waist or shoulders need to be adjusted multiple times, which is more physically demanding. Summary of the invention

[0004] Based on this, it is necessary to provide a multifunctional cervical and lumbar surgical positioning pad to address the above-mentioned technical problems. By adjusting the position and height of the shoulder pads on both sides, the patient's limbs and diseased parts can be stretched out, which is convenient for doctors to perform surgical operations.

[0024] The present invention provides a multifunctional cervical and lumbar surgery position pad, which adjusts the positions of the main body pad 1, the abdomen pad 9 and the leg pad 10 by adjusting the length of the adjusting connecting plate 12 to make them fit the patient's body, and when the patient lies on the main body pad 1, the positions of the shoulder pads 2 on both sides can be adjusted so that the shoulder pads 2 can fit the patient's shoulders, and the height of the adjustment frame 18 can be adjusted by moving the top plate 20, thereby adjusting the height of the two shoulder pads 2, which can stretch the patient's limbs and affected parts, making it convenient for doctors to perform surgical operations, and the positions of the two shoulder pads 2 can be synchronously adjusted when the patient lies on the main body pad 1, avoiding the need to lift the patient up and then adjust the operation, saving physical strength and reducing the patient's discomfort.

[0025] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings. Example

[0028] Please refer to Figure 1 and Figure 2 A multifunctional cervical and lumbar surgery position pad, a main body pad 1, an abdominal pad 9 and a leg pad 10 are distributed in sequence and connected in series through an adjusting connecting plate 12. The positions of the main body pad 1, the abdominal pad 9 and the leg pad 10 are adjusted by adjusting the length of the adjusting connecting plate 12 to make them fit the patient's body and meet the use of patients of different body shapes.

[0029] In addition, if Figure 1 and Figure 2 As shown, the head pad 3 is a two-section structure, and the head pad 3 is installed at the front end of the main body pad 1. The head pad 3 is provided to support the patient's head, and the two-section structure of the head pad 3 is convenient for adjusting its size, so as to better support and fix the patient's head.

[0030] It is worth mentioning that Figure 3 and Figure 4 As shown, the two shoulder pads 2 are respectively installed on both sides of the main body pad 1, and an adjustment frame 18 is fixed to the bottom of the shoulder pad 2 and slides laterally with the main body pad 1 to control the distance between the two shoulder pads 2. A support frame 8 is installed in the main body pad 1, and the adjustment frame 18 moves in the inner cavity of the support frame 8. By moving the adjustment frame 18 laterally along the support frame 8, the distance between the two shoulder pads 2 can be adjusted.

[0031] In addition, a toggle block 19 is vertically slidably connected to the middle of each adjustment frame 18, and the two toggle blocks 19 are connected in series through the adjustment rod 15, and the corresponding positions of the two toggle blocks 19 on the adjustment rod 15 are respectively provided with threads with opposite rotation directions. By moving the toggle block 19, the adjustment frame 18 can be driven to move synchronously, thereby adjusting the lateral position of the shoulder pad 2. Since the two toggle blocks 19 are located on the adjustment rod 15 with opposite rotation directions of the threads, the two shoulder pads 2 can be adjusted to move outward or inward at the same time by rotating the adjustment rod 15, thereby adjusting the spacing of the shoulder pads 2 to make it the same as the shoulder distance of the patient.

[0032] In this embodiment, if Figure 4 As shown, the bottom of each adjustment frame 18 is slidably connected to a top plate 20 for controlling the height of the adjustment frame 18. The contact surface between the top plate 20 and the adjustment frame 18 is an inclined surface. A push block 21 slidably connected to the support frame 8 is fixed on one side of the top plate 20. The top plate 20 is moved by moving the push block 21. Due to the inclined structure of the contact surface between the top plate 20 and the adjustment frame 18, the adjustment frame 18 can be controlled to move up and down by moving the top plate 20 horizontally, thereby adjusting the height of the shoulder pad 2 located on the top of the adjustment frame 18 and adjusting the vertical position of the shoulder.

[0033] In addition, an adjusting rod 16 rotatably connected to the supporting frame 8 is provided above the pushing block 21. The adjusting rod 16 is linked to the pushing block 21 through a gear rack assembly 22. When the positions of the pushing block 21 and the top plate 20 need to be adjusted, the adjusting rod 16 is rotated and the gear rack assembly 22 is used to push the pushing block 21 to move, thereby controlling the pushing block 21 and the top plate 20 to move synchronously.

[0034] Through the above structural design, a support frame 8 is set in the middle of the main body pad 1. The support frame 8 plays the role of an internal hard support, which can control the two shoulder pads 2 to move stably at the support frame 8, adjust the height and spacing of the shoulder pads 2, and play a hard supporting role for the patient's shoulders, so that the patient's limbs can be better stretched, which is convenient for doctors to perform surgical operations.

[0035] It is worth mentioning that Figure 1 , Figure 2 and Figure 7As shown, the main body pad 1, the head pad 3, the abdomen pad 9 and the leg pad 10 are all flexible pads, and the main body pad 1, the abdomen pad 9 and the leg pad 10 are all individually installed with auxiliary heating ports 13, and the auxiliary heating ports 13 at each position can be connected to the hot air ports in the operating room, and the leg pad 10 is concavely provided with a support groove 11 for accommodating the knees, providing a comfortable feeling for the patient, and the soft main body pad 1 wraps the outer side of the support frame 8 to avoid causing discomfort to the patient, the abdomen pad 9 supports the patient's abdomen to stretch the patient's back, and the leg pad 10 supports the patient's legs, and the support groove 11 matches the patient's knees, so as to better support and position the patient's legs.

[0036] And if Figure 7 As shown, by setting connecting pipes inside the main body pad 1, the abdomen pad 9 and the leg pad 10, multiple auxiliary heating ports 13 in each pad block are connected, and an air inlet interface is set at the pipe, which is connected to the hot air interface in the operating room through a pipe, so as to facilitate the access to the heat source, and each auxiliary heating port 13 can control the air outlet individually, and the auxiliary heating position can be adjusted according to the demand to provide a comfortable environment for the patient.

[0037] In order to prevent the patient from catching a cold during surgery, auxiliary heating ports 13 can be separately installed on the main pad 1, the abdominal pad 9 and the leg pad 10. The auxiliary heating ports 13 can be used to warm the patient. The auxiliary heating ports 13 at each position can be connected to the hot air ports in the operating room to warm the patient. Hot air heating can be performed on the auxiliary heating ports 13 at the positions of the main pad 1, the abdominal pad 9 and the leg pad 10 as needed. Each position can be heated independently, and the internal space of the main pad 1, the abdominal pad 9 and the leg pad 10 can be heated to make the contact parts of the patient comfortable.

[0038] The two sides of the main body pad 1 and the abdominal pad 9 are connected by a limiting rope 30, two transverse positioning ropes 31 are sleeved on one of the limiting ropes 30, and the other end of the transverse positioning rope 31 is fixed with a buckle that can be engaged with the limiting rope 30 on the other side, and two parallel longitudinal positioning ropes 32 are connected in parallel between the two transverse positioning ropes 31. The two transverse positioning ropes 31 and the two longitudinal positioning ropes 32 form a tic-tac-toe structure, which can locate the surgical site on the back and both sides of the patient's surgical site, which is convenient for doctors to perform surgical operations. The surgical site can be reused to intuitively and conveniently display the patient's surgical site, avoiding the traditional operation method of cutting a display port on the cloth, which is easy to operate and saves resources.

[0039] By moving the end of the transverse positioning rope 31 which is sleeved on the limiting rope 30, adjusting the position and spacing between the two, and tying the two ends of the longitudinal positioning rope 32 to appropriate positions on the transverse positioning rope 31, a tic-tac-toe structure for locating the surgical site is formed. The limiting rope 30, the transverse positioning rope 31 and the longitudinal positioning rope 32 can be elastic ropes, so that the appropriate length can be adjusted as needed.

[0040] like Figure 2 and Figure 6 As shown, a breathing tube clamp 17 is installed on the head pad 3, and the breathing tube clamp 17 clamps and fixes the patient's breathing tube, making it convenient to fix the breathing tube. Example

[0041] The multifunctional cervical and lumbar surgery position cushion provided in Example 1 is further optimized. Specifically, Figure 4 and Figure 5 As shown, the adjusting rod 2 15 and the adjusting rod 1 16 are arranged in parallel, and the ends of the adjusting rod 2 15 and the adjusting rod 1 16 are both installed with a driven gear 23, and a driving gear 24 connected to the support frame 8 for rotation is arranged between the two driven gears 23, and the driving gear 24 is meshed with a switching gear 25 through teeth, and the switching gear 25 can be respectively meshed with the driven gear 23 located on the adjusting rod 2 15 or the adjusting rod 1 16 through a slide groove located on the support frame 8, and the switching gear 25 is driven to rotate by rotating the driving gear 24. When the switching gear 25 is rotated, the switching gear 25 is rotated. The wheel 25 moves to the driven gear 23 on the adjusting rod 15 and drives the adjusting rod 15 to rotate synchronously, and the positive and negative rotation of the driving gear 24 drives the adjusting rod 15 to rotate forward and reversely, thereby adjusting the distance between the two shoulder pads 2; when the switching gear 25 moves to the driven gear 23 on the adjusting rod 1 16 and drives the adjusting rod 16 to rotate synchronously, the positive and negative rotation of the driving gear 24 can drive the adjusting rod 16 to rotate forward and reversely, thereby adjusting the position of the pushing block 21 and the top plate 20, and then adjusting the height of the two shoulder pads 2.

[0042] In addition, if Figure 4 and Figure 5 As shown, a driving rocker 14 is installed on the driving gear 24, and a replacement disk 27 is installed on the shaft of the driving rocker 14 through a bearing. The replacement disk 27 is rotatably connected with a replacement shaft 26 installed with the switching gear 25. By turning the replacement disk 27, the replacement shaft 26 can be synchronously driven to move, thereby driving the switching gear 25 to move between the two driven gears 23, and a lever can be provided on the replacement disk 27 to facilitate the control of the replacement disk 27. After the replacement disk 27 is turned, the lever can lock the position of the replacement disk 27, thereby fixing the position of the switching gear 25.

[0043] Through the above-mentioned structural design, medical staff can conveniently drive the driving gear 24 to rotate by rotating the driving rocker 14, and control the switching gear 25 to move between the two driven gears 23 by turning the replacement disk 27. The driving rocker 14 can be used to independently control the forward and reverse rotation of the adjusting rod 2 15 or the adjusting rod 1 16, thereby controlling the spacing or height adjustment of the shoulder pad 2, so that the patient's limbs can be better stretched, which is convenient for the doctor to perform surgery. Example

[0044] The multifunctional cervical and lumbar surgery position cushion provided in Example 1 is further optimized, such as Figure 1 and Figure 6 As shown, the head pad 3 is composed of a head pad 1 4 and a head pad 2 5 which are interlocked with each other, and an adjusting rod assembly 1 6 which is plugged into the head pad 1 4 is fixed to the end of the head pad 2 5, and an adjusting rod assembly 2 7 which is plugged into the head pad 2 5 is fixed to the end of the head pad 1 4 away from the adjusting rod assembly 6, and the ends of the adjusting rod assembly 1 6 and the adjusting rod assembly 2 7 are both connected to the supporting frame 8. By pulling the adjusting rod assembly 2 7 to drive the head pad 1 4 to move, the support of the head pad 1 4 to the chin of the patient's head can be controlled, and by pulling the adjusting rod assembly 1 6 to control the movement of the head pad 2 5, the distance between the head pad 1 4 and the head pad 2 5 can be adjusted to adapt to the head sizes of different patients and make the patients more comfortable. When a gap is formed between the adjusted head pad 1 4 and the head pad 2 5, it can be filled with a soft cushion to avoid discomfort to the patient's face.

[0045] In addition, if Figure 6 As shown, the adjusting rod assembly 1 6 and the adjusting rod assembly 2 7 are both embedded with locking balls 29 at the corresponding positions of the support frame 8, and a control rod 28 plugged with the corresponding adjusting rod assembly 1 6 or adjusting rod assembly 2 7 is installed on the inner side of the locking ball 29. A receiving groove is provided at the corresponding position of the control rod 28 and the locking ball 29. When it is necessary to adjust the insertion distance of the adjusting rod assembly 1 6 or the adjusting rod assembly 2 7 and the support frame 8, the control rod 28 on the adjusting rod assembly 1 6 or the adjusting rod assembly 2 7 is pushed so that the receiving groove on the control rod 28 corresponds to the locking ball 29, and the locking ball 29 enters into The inner cavity of the adjusting rod assembly 1 6 or the adjusting rod assembly 2 7, at this time, the adjusting rod assembly 1 6 or the adjusting rod assembly 2 7 can be smoothly plugged into the supporting frame 8. On the contrary, when the control rod 28 is released, the spring located at the end of the control rod 28 can push the control rod 28 to reset, so that the accommodating groove on the control rod 28 is misaligned with the locking ball 29. At this time, the part structure of the locking ball 29 is pushed out to the outside of the adjusting rod assembly 1 6 or the adjusting rod assembly 2 7, and contacts with the supporting frame 8, locking the adjusting rod assembly 1 6 or the adjusting rod assembly 2 7, thereby fixing the position of the head pad 1 4 or the head pad 2 5.
