Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically an integrated body positioning support device for breast and axillary surgery. Background Technology

[0002] There are many types of breast surgeries, including benign breast tumor resection and biopsy, extended local excision for breast cancer, simple mastectomy, sentinel lymph node resection and biopsy in the axilla, axillary lymph node dissection, and modified radical mastectomy for breast cancer. Breast cancer surgery involves the affected breast and the ipsilateral axilla. The axilla is relatively concealed in a normal posture, so the patient needs to abduct their arm to expose the surgical area during surgery. Although the breast is located on the surface of the body, the patient's position also needs to be adjusted simultaneously to better expose the axilla. Therefore, a high degree of exposure of the surgical area is often required during surgery, necessitating that the patient maintain a good position before and during the procedure.

[0003] Currently, the common clinical positioning preparation method is as follows: before surgery, the patient lies flat on the operating table with their head resting on the pillows on the operating table. A positioning pad is placed on the operating table corresponding to the affected side's shoulder and back to elevate the affected breast, making the surgical side higher than the contralateral side. Additionally, the patient's affected upper limb is properly abducted and fixed. Different hospitals use different methods for upper limb fixation; some simply use an external arm support to abduct the upper arm, forming a 90-degree angle with the body, while others suspend the upper limb upwards and towards the head to expose the axillary surgical area.

[0004] During breast surgery, if patients are positioned as described above, the following problems arise: 1. The height or size of the positioning pads currently used in some hospitals is relatively fixed, which cannot meet the needs of patients with different body types, weights, heights, and arm lengths, thus affecting the surgical field of vision and the assessment of the axillary structure; 2. Currently, the elevation of the shoulder and back and the suspension or abduction of the arm are handled in two separate ways, resulting in a large number of auxiliary instruments stored in the operating room, a longer preoperative preparation time, and an increased workload for medical staff; 3. The positioning pad may gradually slide off the operating table as the patient's body is continuously compressed and the surgical procedure is performed, resulting in the loss of the height difference between the affected and unaffected sides, and insufficient exposure of the breast and axillary area; 4. If the size of the positioning pad under the shoulder and back is fixed, the overall adjustment is required if the height of the pad is not satisfactory during the operation. The lateral tilt of the operating table necessitates additional preoperative patient positioning, increasing the workload for medical staff and posing a risk of medical accidents. 5. Currently, there are no dedicated breast cancer suspensory limb suspension devices available clinically (shared hand support boards are commonly used). If positioning is done using suspensory limbs, bandages are often used to locally bind and fix the wrist to an inverted L-shaped support frame. Improper tightness can lead to skin damage, local ischemia, and distal numbness at the binding site due to excessive tightness, or limb detachment and surgical site contamination due to excessive looseness. 6. Breast cancer general anesthesia surgery typically lasts 2-4 hours. Improper positioning can cause discomfort such as shoulder, neck, and upper limb pain and numbness after anesthesia recovery, and even muscle spasms, resulting in poor patient comfort during surgery.

[0015] As a further embodiment of this utility model: one end of the threaded rod is connected to a bevel gear set, and the bevel gear set is connected to the output shaft of the drive motor located at the bottom of the pad.

[0016] As a further improvement of this utility model, the lifting angle of the support plate relative to the pad plate can be flexibly adjusted by wireless remote control.

[0017] As a further embodiment of this utility model: the locking structure includes a clamping part that slides and fits with the fixed shaft, a "U"-shaped opening is formed on one side of the clamping part, a first locking bolt is provided on one side of the "U"-shaped opening, and a wrench is rotatably installed on the end of the first locking bolt away from the clamping part.

[0018] As a further embodiment of this utility model, the locking structure further includes a locking device disposed on the clamping part and on the side away from the "U"-shaped opening, the locking device being used to fix the clamping part to the fixed shaft.

[0019] As a further improvement of this utility model: a limiting ring is provided on the side mounting rod, and a collar connected to one end of the screw can be fitted onto the side mounting rod;

[0020] The locking nut, which is threaded with the side mounting rod, can engage with the limiting ring to axially lock the collar.

[0021] As a further embodiment of this utility model: a movable part is slidably installed at the other end of the screw, and a second locking bolt is provided on the movable part, the second locking bolt being able to penetrate the movable part and abut against the screw;

[0022] An adjusting rod is slidably mounted on the end of the second locking bolt.

[0023] As a further embodiment of this utility model: the arm tightening assembly includes an arc-shaped component that is detachably connected to the movable component. One end of the arc-shaped component is rotatably fitted with a tightening strip, and the other end is rotatably fitted with a connecting component. The tightening strip is provided with multiple sets of reverse teeth at equal intervals along its length direction, and the reverse teeth are adapted to the engaging components provided on the connecting component.

[0024] As a further improvement of this invention: a protective gel layer is provided on the inner side of the arm tightening component to prevent skin abrasion.

[0025] As a further improvement of this utility model, the exposed surfaces of all components of the integrated breast and axillary surgery positioning support device have an insulating coating to prevent the risk of electric shock caused by the use of an electrocautery knife during surgery.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] The integrated positioning support device for breast and axillary surgery provided by this utility model is fixed to the operating table through an adjustable joint. It can be used as an accessory that can be adapted to most operating tables without the need for a special bed, and has strong applicability.

[0028] This utility model provides an integrated positioning support device for breast and axillary surgery, comprising a double-peaked soft pad, a support plate, and an adjustment component. Firstly, the double-peaked soft pad fills the gap between the patient's body and the operating table after the affected side is lifted, and provides some support to the spine. When the support plate is deflected, the patient's body tilts to the side, creating a gap between the back of the patient's spine and the operating table, which gradually changes the surgical position over time. This device increases positional stability by providing a certain degree of support to the patient's body (especially both sides of the spine), improving patient comfort during prolonged periods of side tilting. Secondly, the deflection of the support plate allows the patient's body to tilt to a predetermined angle, making the patient's position more suitable for actual operation. It can also be adjusted according to the needs of different surgeons, facilitating full exposure of the breast and axilla during surgery, thus simplifying the surgeon's operation. Meanwhile, the adjustment component has a self-locking effect, so that when the angle of the support plate reaches the predetermined angle, the position of the threaded sleeve will not change when the drive motor is powered off and stops working, thus making the support plate have a more stable deflection state, thereby improving the stability of the patient's position in the tilting state.

[0029] The locking structure improves the stability of the pad on the operating table, preventing the pad from sliding relative to the operating table due to the pressure exerted on the pad by the patient's body in a tilted position. This enhances the stability of the pad on the operating table, prevents changes in the patient's position due to changes in the pad's position during surgery, and improves the stability of the patient's body in a tilted position.

[0030] The designed arm-tightening component provides a stable tightening effect on the patient's wrist while traction on the arm, preventing bending and obstruction of the surgical field. The adjustable screw angle allows for adjustment of the arm's angle as needed, facilitating breast and armpit exposure. The movable component, which moves the arm-tightening component along the screw, accommodates patients with varying arm lengths, enhancing the device's versatility. Furthermore, a protective gel layer inside the arm-tightening component, made of a high-polymer material, offers excellent softness and support. This non-conductive, easily cleanable gel resists bacterial growth, prevents skin abrasion, and significantly improves comfort.

[0031] The integrated positioning support device for breast and axillary surgery provided by this utility model uses a remote wireless control to raise the support plate, which can be adjusted at will during the operation and save manpower for conventional positioning pads before the operation.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Furthermore, the elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0041] Please see Figures 1-6 In this embodiment of the present invention, an integrated positioning support device for breast and axillary surgery includes: a pad 1, an adjustment component, a fixed shaft 11, and a side mounting rod 16.

[0042] The pad 1 is provided with a double-peak soft pad 2 and a support plate 3. Specifically, the support plate 3 is rotatably mounted on the pad 1.

[0043] The adjustment component is disposed on the pad 1 and connected to the support plate 3, and the adjustment component can drive the support plate 3 to deflect relative to the pad 1.

[0044] The adjustment assembly includes a threaded rod 6 and a guide 9 disposed on the pad 1. A threaded sleeve 7 is disposed on the threaded rod 6 and threadedly connected thereto. A follower rod 8 is slidably mounted on the guide 9 and is fixedly connected to the threaded sleeve 7.

[0045] A support rod 10 is rotatably mounted on the follower rod 8. The end of the support rod 10 away from the follower rod 8 is rotatably connected to the support plate 3. It should be noted that when the support plate 3 is parallel to the pad 1, the support rod 10 is in an inclined state so that when the threaded sleeve 7 moves along the length direction of the threaded rod 6, the support rod 10 can lift the support plate 3, thereby causing the support plate 3 to deflect.

[0046] One end of the threaded rod 6 is connected to a bevel gear set 5, which is connected to the output shaft of the drive motor 4 located at the bottom of the pad 1.

[0047] In use, the pad 1 is laid flat on the operating table. The double-peaked soft pad 2 fills the gap between the patient's body and the operating table after the affected side is lifted, providing some support to the spine. This prevents the patient's body from tilting when the support plate 3 deflects, thus avoiding a gap between the patient and the operating table that could cause the body to bend and collapse, altering the surgical position. Furthermore, by providing support to the patient's body (especially both sides of the spine), postural stability is increased, thereby improving patient comfort in a tilted position. Further, depending on the actual surgical position, the drive motor 4 can be controlled wirelessly. The output shaft of the drive motor 4 drives the connected bevel gear set 5, causing the threaded rod 6 to rotate. This causes the threaded sleeve 7, which is adapted to the threaded rod 6, to move along the length of the threaded rod 6, thus moving the follower rod 8. Simultaneously, supported by the support rod 10, the support plate 3 can deflect to tilt the patient's body to a predetermined angle, facilitating full exposure of the breast and armpit during surgery, thus allowing for easier operation by different surgeons.

[0048] Furthermore, since the threaded rod 6 and the threaded sleeve 7 are connected by threads, and the threaded connection has a self-locking effect, when the angle of the support plate 3 reaches the predetermined angle, the position of the threaded sleeve 7 will not change when the drive motor 4 is de-energized and stops working, thus giving the support plate 3 a more stable deflection state, thereby improving the stability of the patient's position in the tilting state.

[0049] By setting the bevel gear set 5, the drive motor 4 can be installed at the lower part of the pad 1, and the drive motor 4 is located at the bottom of the pad 1 protruding from the side of the operating table. This ensures power transmission while avoiding affecting the surgeon's position due to the drive motor 4 being installed on the side of the pad 1, thus improving the surgeon's convenience during the operation.

[0050] It should also be noted that the lifting angle of the support plate 3 relative to the pad 1 can be flexibly adjusted via wireless remote control. The drive motor 4 and the controller (not shown in the figure) are wirelessly connected. The controller can control the number of rotations of the drive motor 4 in the forward and reverse directions, thereby realizing the remote adjustment of the predetermined angle of the support plate 3.

[0051] The tilt angle of the support plate 3 is limited, typically with a maximum lifting angle of 30°. Limiting the tilt angle of the support plate 3 prevents excessive tilting that could cause the patient's body to tilt too far to one side, resulting in lower body compression and discomfort. A soft pad is provided on the upper part of the pad 1 to ensure patient comfort after passive tilting.

[0052] Please see Figures 1-3 The fixed shaft 11 is provided in two sets and connected to the pad 1. The end of the fixed shaft 11 away from the pad 1 is provided with a locking structure, which enables the fixed shaft 11 to be connected to the operating table.

[0053] The locking structure includes a clamping part 12 that slides and engages with the fixed shaft 11. A "U"-shaped opening is formed on one side of the clamping part 12. A first locking bolt 13 is provided on one side of the "U"-shaped opening. A wrench 14 is rotatably mounted on the end of the first locking bolt 13 away from the clamping part 12.

[0054] The locking structure also includes a locking device 15 disposed on the clamping part 12 and on the side away from the "U"-shaped opening, the locking device 15 being used to fix the clamping part 12 to the fixed shaft 11.

[0055] Most standard operating tables have a suspended structure, with the mattress and metal frame integrated. This invention features a pad 1 placed on the operating mattress to support the patient's shoulders and back. It is fixed to the metal frame on one side beneath the mattress, serving as an auxiliary support and restraint device. This device elevates the shoulder and back on the surgical side and restrains the arm in patients undergoing breast and axillary surgery, exposing the surgical area and providing the surgeon with a better field of vision. The widths of the double-peaked pad 2 and the support plate 3 are not proportionally distributed; the double-peaked pad 2 is narrower than the support plate 3, offset from the central axis of the operating table's length, and closer to the surgical side, making it suitable for patients of different body types in a lateral decubitus position.

[0056] In use, the pad 1 is first laid flat on the operating table. Then, the position of the clamping part 12 on the fixed shaft 11 is adjusted using the locking device 15 so that the "U"-shaped opening of the clamping part 12 is aligned with the edge of the operating table. The edge of the operating table is then inserted into the "U"-shaped opening. At this point, the first locking bolt 13 can be rotated using the wrench 14, and screwed into the "U"-shaped opening until it abuts against the edge of the operating table. This locks the fixed shaft 11 to the operating table, improving the stability of the pad 1 on the operating table and preventing the pad 1 from slipping relative to the operating table due to pressure from the patient's body when tilted. The position of the clamping part 12 on the fixed shaft 11 is flexibly adjustable to accommodate various sizes and models of operating tables.

[0057] Please see Figure 1 , Figure 5 The side mounting rod 16 is mounted on the fixed shaft 11, and a screw 20 is detachably and rotatably mounted on the side mounting rod 16. An arm tightening assembly is provided at the end of the screw 20 away from the side mounting rod 16. The position of the arm tightening assembly on the screw 20 is adjustable. Specifically:

[0058] A limiting ring 17 is provided on the side mounting rod 16, and a collar 18 connected to one end of the screw 20 can be sleeved on the side mounting rod 16;

[0059] The locking nut 19, which is threadedly engaged with the side mounting rod 16, can engage with the limiting ring 17 to axially lock the collar 18;

[0060] The other end of the screw 20 is slidably mounted with a movable part 21, and a second locking bolt 22 is provided on the movable part 21. The second locking bolt 22 can pass through the movable part 21 and abut against the screw 20.

[0061] An adjusting rod 23 is slidably mounted on the end of the second locking bolt 22.

[0062] First, the collar 18 can be inserted into the corresponding side mounting rod 16 as needed. Rotating the collar 18 causes the screw 20 to deflect around the side mounting rod 16 as its rotation center. Once the screw 20 deflects to a predetermined angle, the locking nut 19 is screwed into the corresponding side mounting rod 16 until the collar 18 contacts the limiting ring 17. The limiting ring 17 has limiting teeth that match the cross-section of the collar 18. Contacting the collar 18 restricts its rotation around the side mounting rod 16, thus axially locking the collar 18. At this point, the screw 20 maintains the predetermined deflection, ensuring that the patient's arm, after being secured by the arm restraint assembly, is fixed at a predetermined angle. This further improves the patient's stability and maintains the optimal surgical position.

[0063] Furthermore, once the deflection angle of the screw 20 is determined, the adjusting rod 23 can drive the second locking bolt 22 to screw in or out relative to the movable member 21. When the second locking bolt 22 is screwed out relative to the movable member 21, the second locking bolt 22 can separate from the screw 20, thereby allowing the movable member 21 to slide relative to the screw 20. When the arm restraint assembly on the movable member 21 can fix the patient's wrist, the second locking bolt 22 can be screwed in relative to the movable member 21, thereby locking the movable member 21 against the screw 20 and improving the stability of the movable member 21 in this state.

[0064] With the above settings, on the one hand, the angle of the patient's arm can be adjusted according to actual needs, which further facilitates the exposure of the breast and armpit. On the other hand, since the movable part 21 can drive the arm tightening component to move on the screw 20, the movable part 21 can meet the needs of patients with different arm lengths, so that the arm can be fixed for patients with different arm lengths, thus improving the applicability of the device.

[0065] Please see Figure 1 , Figure 3 , Figure 6 The arm tightening assembly includes an arc-shaped component 24 detachably connected to the movable component 21. One end of the arc-shaped component 24 is rotatably mounted with a tightening strip 25, and the other end is rotatably mounted with a connector 27. The tightening strip 25 is provided with multiple sets of reverse teeth 26 at equal intervals along its length direction. The reverse teeth 26 are adapted to the engaging parts 28 provided on the connector 27.

[0066] Among them, the arc-shaped component 24, the tightening strip 25 and the connecting component 27 are replaceable parts, and a protective gel layer made of gel material is provided on the inner side to prevent the skin of the patient's wrist from being abraded under the action of tightening force when the patient's wrist is tightened.

[0067] Furthermore, when fixing the patient's wrist, the tightening strip 25 is inserted into the locking member 28. The locking member 28 is provided with locking teeth that are compatible with the reverse teeth 26. The two work together to prevent the tightening strip 25 from slipping out after entering the locking member 28, thereby achieving a relatively stable tightening effect on the patient's wrist and pulling the patient's arm to prevent the patient's arm from bending and obstructing the surgical field of vision.

[0068] Furthermore, the exposed surfaces of all components of the integrated positioning support device for breast and axillary surgery provided by this utility model have an insulating coating to prevent the risk of electric shock caused by the use of an electrocautery knife during surgery.
