Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a positioning device for pain management surgery. Background Technology

[0002] In pain management surgeries, precise positioning devices are crucial for ensuring clear surgical visibility, reducing operational errors, and minimizing the risk of iatrogenic injury. Spinal surgery, a common procedure in pain management that demands high patient stability in the supine position, requires specialized positioning devices to precisely fix and comfortably support key anatomical areas such as the head, chest, and buttocks. In particular, it is essential to consider the appropriate arch of the abdomen when the patient is in the prone position to avoid compression of abdominal organs and alteration of the physiological curvature of the spine, thereby ensuring the safety and precision of the surgical procedure.

[0003] Existing support devices for adjusting the abdominal arch, such as the AOTA16A1 surgical abdominal support, mainly include a hollow limiting rod with a sandwich panel, a positioning rod inserted into the sandwich panel and connected at one end to a pull plate and an arc plate, a spring connected to the arc plate, an adjusting rod with multiple positioning holes, a connecting frame, a padded support plate, and a base equipped with casters and an electric telescopic rod at the bottom. The arch curvature is adjusted by pulling the pull plate to move the positioning rod out of the positioning hole, adjusting the extension length of the adjusting rod to adjust the arch curvature of the support plate, and releasing the pull plate to reset the spring and drive the positioning rod to insert into the corresponding positioning hole to complete the fixation.

[0004] Existing technologies for adjusting the abdominal support curvature during surgery mostly adopt the mode of adjusting the overall curvature of the support unit. This design has obvious limitations when dealing with patients with abnormal curvature of local segments of the spine. It is difficult to achieve precise adaptation of the patient's spine and cannot adjust the spine to the ideal physiological curvature that meets the requirements of surgical operation. Therefore, there is an urgent need to develop a positioning device specifically for pain management surgery to address this clinical pain point. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a dedicated positioning device for pain management surgeries. Addressing the limitations of traditional abdominal support arch adjustment methods in meeting the individualized needs of patients with abnormal curvature in specific spinal segments, this invention optimizes the design of a multi-point contact arch adjustment mechanism, enhancing the adaptability of spinal position adjustment to the patient's spinal shape during supine spinal surgery.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A positioning device for pain management surgery includes a lifting operating table, an abdominal arch adjuster is fixedly connected to the output plane of the lifting operating table, the abdominal arch adjuster includes a housing, a support window is provided on the top of the housing, and a flexible padding layer is provided at the support window to provide a flexible contact surface for contact with the patient's abdomen; a chain arc plate skeleton with an arc-shaped configuration and adjustable arch is provided inside the support window;

[0007] An adjustment drive cavity is provided inside the outer shell at the position corresponding to the support window. Several contact-type camber adjustment components are provided inside the adjustment drive cavity. Each contact-type camber adjustment component makes single-point contact with the bottom of the chain arc plate skeleton. The contact-type camber adjustment components adjust the local camber of the chain arc plate skeleton by applying a telescopic support force to the corresponding contact point of the chain arc plate skeleton. A controller is configured inside the outer shell, and the contact-type camber adjustment components are all connected to the controller signal.

[0008] One side of the outer casing is equipped with an auxiliary adjustment component for projecting simulated images of the patient's spinal morphology.

[0009] The technical principle of the above solution is as follows: This solution is based on the existing lifting operating table to provide basic height adjustment for abdominal support. It integrates an abdominal arch adjuster to adjust the arch of the abdominal support. In the abdominal arch adjuster, an adjustable chain arc plate skeleton is set up. Several contact adjustment components are used to apply local support force to the bottom of the chain arc plate skeleton to achieve overall arch adjustment and local arch adjustment. At the same time, a flexible padding component is used to provide comfortable contact with the patient's abdomen after the arch adjustment. In addition, an auxiliary adjustment component is set up to project spinal images to assist in the adjustment of spinal posture.

[0010] The above approach has the following beneficial effects:

[0011] 1. This solution applies multi-point local support force to the chain arc frame through several contact adjustment components to achieve overall or local arch adjustment. This solves the problem that the existing overall arch adjustment mode is difficult to adapt to patients with local spinal abnormalities. It can achieve precise support for special segments of the spine and avoid fitting gaps or excessive compression.

[0012] 2. This approach integrates local arch adjustment capabilities to adjust the patient's spine to the ideal physiological curvature that meets the surgical requirements, thereby improving the clarity of the surgical field and the safety of the procedure.

[0013] 3. This solution uses an auxiliary adjustment component that can project the shape of the patient's spine as a reference for posture adjustment, thereby improving the accuracy and convenience of adjustment and reducing operational errors through visualization.

[0014] Furthermore, the flexible padding component includes a stretchable silicone layer, with both ends of the silicone layer fixedly connected to the adjustment drive cavity.

[0015] Beneficial effects: The stretchable silicone layer, as a flexible padding component, can adapt to the dynamic changes in the abdominal contour and support curvature of different patients, providing a comfortable contact experience and laying the foundation for subsequent arch adjustment.

[0016] Furthermore, the chain-type arc frame includes four joints, several horizontally arranged support arc strips, and several connecting arc plates. The support arc strips and connecting arc plates are connected in sequence using a hinged series structure to form a continuous frame. The four joints hinge the continuous frame to the side wall of the support window.

[0017] Beneficial effects: The chain-like arc frame is formed by the hinged series of support arc bars and connecting arc plates. The continuous frame is hinged to the side wall of the support window using four joints, so that the continuous frame has adjustable arch. The overall abdominal arch support is divided into multiple arc-shaped hinged units, allowing relative movement of each unit, thereby realizing flexible adjustment of the overall or local arch to adapt to the spinal morphology needs of different patients.

[0018] Furthermore, the curvature of the supporting arc strip is the same as that of the connecting arc plate.

[0019] Beneficial effects: This design ensures that the supporting arc strip and the connecting arc plate have the same curvature, ensuring the consistency of the overall curvature of the skeleton after the articulation and connection, avoiding movement jamming or unsmooth support caused by curvature differences, improving the smoothness and stability of the skeleton's arch adjustment, and ensuring uniform support for the patient's abdomen.

[0020] Furthermore, the hinge connection between any supporting arc strip and the adjacent connecting arc plate is specifically as follows:

[0021] An arc-shaped groove is provided on the supporting arc strip at the overlapping part of the adjacent connecting arc piece. A sliding piece is fixedly connected to the connecting arc piece corresponding to the arc groove. The sliding pieces are all slidably connected in the arc groove. The curvature of the arc groove corresponds to the curvature of the supporting arc strip.

[0022] Beneficial effects: This design achieves the hinged connection between adjacent supporting arc bars and connecting arc plates by cooperating with the arc grooves of the supporting arc bars and the sliding plates of the connecting arc plates. That is, the sliding adjustment of a single hinged unit allows the continuous skeleton as a whole to adjust the relative angle through the dynamic deformation and displacement of each unit when subjected to external force, thereby achieving adaptive adjustment of the arch and adapting to the shape requirements of the supported object.

[0023] Furthermore, the number of contact-type camber adjustment components is odd and no less than 5.

[0024] Beneficial effects: The design with an odd number of components ensures that there are contact arch adjustment components at the bottom of the continuous skeleton as a central reference anchor point to provide stable support. The requirement of no less than 5 contact arch adjustment components allows for the distribution of more adjustment points on both sides of the central reference anchor point, which can apply support force to local small areas, improve the accuracy of adaptation to asymmetrical shapes or personalized needs on both sides of the spine, and meet the precise support requirements of special patients.

[0025] Furthermore, each contact-type camber adjustment component includes a fixed base rod and a hinged top rod. The fixed base rod is fixedly connected to the adjustment drive cavity. An electrically controlled telescopic cylinder is provided between the fixed base rod and the hinged top rod. The bottom of the electrically controlled telescopic cylinder is hinged to the fixed base rod, and the output shaft of the electrically controlled telescopic cylinder is hinged to the hinged top rod.

[0026] Each hinged top rod is equipped with a contact arc plate, and the curvature of the contact arc plate is the same as that of the connecting arc plate.

[0027] Beneficial effects: This design connects the fixed base rod and the hinged top rod through an electrically controlled telescopic cylinder, enabling the contact arc plate to apply a telescopic support force in the height direction to the entire continuous frame. Each electrically controlled telescopic cylinder operates independently to achieve local camber adjustment, while the controller provides unified control to ensure the accuracy and coordination of the adjustment, thereby improving the efficiency and precision of camber adjustment.

[0028] Furthermore, the connection between the contact arc plate and the hinged top rod adopts a bearing-type rotating connection.

[0029] Beneficial effects: The design of the contact arc plate and the hinged top rod bearing-type rotating connection allows the contact arc plate to rotate as the contact point slides, reducing the probability of the contact arc plate getting stuck on the bottom surface of the continuous frame and making it difficult to slide. This ensures smooth adjustment of the overall arch of the continuous frame and adapts to the adjustment needs of dynamic sliding of multiple contact points.

[0030] Furthermore, the auxiliary adjustment component includes a sliding arm that is slidably connected to the side wall of the housing. The sliding arm includes a collaborative robotic arm with height and angle adjustment functions. The output end of the collaborative robotic arm is fixedly connected to a projector, and the projector is signal-connected to the controller.

[0031] The controller acquires the patient's spinal scan images based on an external platform, and then transmits signals to the projector to project the spinal scan images onto the patient's side.

[0032] Beneficial effects: This design uses a collaborative robotic arm to adjust the position and angle of the projector, and the controller transmits the patient's spinal scan image and projects it to the patient's side, allowing the adjuster to make precise arch adjustments by intuitively comparing the image, improving adjustment accuracy and convenience, and simplifying the operation steps.

[0033] Furthermore, the output end of the collaborative robotic arm is also fixedly connected to a camera tracking device for image locking and positioning with displacement tracking capability, and the camera tracking device is connected to the controller signal.

[0034] Beneficial effects: This design uses a camera tracking device to lock and position the patient's side and track their displacement in real time, ensuring that the projected spinal image is always on the patient. This improves the accuracy and real-time performance of the image reference during adjustment, and eliminates the need for frequent manual adjustments to the projector to maintain a stable image, thus enhancing the convenience and efficiency of adjustment.

[0035] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0044] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0045] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] The following detailed description illustrates the specific implementation method:

[0048] Example 1:

[0049] This embodiment provides a dedicated positioning device for pain management surgery, specifically as follows: Figure 1 Combination Figure 2 As shown, the device includes a lifting operating table 1 (designed with reference to the lifting operating table in the existing AOTA16A1 type abdominal support). An abdominal arch adjuster 2 is fixedly connected to the output plane of the lifting operating table 1 by a buckle. The abdominal arch adjuster 2 includes a housing 201. A support window 202 is provided on the top of the housing 201. A flexible padding component 203 is provided at the support window 202 to provide a flexible contact surface for contact with the patient's abdomen.

[0050] The flexible padding component 203 includes a stretchable silicone layer, with both ends of the silicone layer fixedly connected to the adjustment drive cavity 209. The stretchability of the silicone layer can adapt to the dynamic changes in the abdominal contour and support curvature of different patients. The flexible material can provide a comfortable contact experience, and the structure of fixing both ends to the adjustment drive cavity 209 lays the foundation for subsequent adjustment of the support curvature.

[0051] Current surgical abdominal support curvature adjustment techniques mostly adopt the overall curvature adjustment mode of the support unit (the overall curvature is adjusted continuously). This adjustment mode is difficult to achieve precise adaptation to the spine of some special patients and cannot adjust their spine to the ideal physiological curvature that meets the requirements of surgical operation. For example, for patients with local kyphosis or scoliosis in a certain segment of the spine, the overall curvature adjustment mode cannot adjust the support curvature separately for the abnormal segment, resulting in a gap or excessive compression between the abnormal segment and the support surface.

[0052] Therefore, the special feature of this embodiment lies in its specific combination Figure 2 , Figure 3 and Figure 4 As shown:

[0053] The supporting window 202 is equipped with a chain-type arc-shaped frame with adjustable arch. The chain-type arc-shaped frame includes four joints 204, several horizontally arranged supporting arc strips 205, and several connecting arc strips 206. The supporting arc strips 205 and the connecting arc strips 206 are connected sequentially in a hinged series structure. The four joints 204 hinge this continuous frame to the side wall of the supporting window 202. Specifically, the hinge between any supporting arc strip 205 and the adjacent connecting arc strip 206 is as follows:

[0054] Combination Figure 3 and Figure 5 As shown, an arc-shaped groove 207 is formed on the supporting arc strip 205 at the overlapping part of the adjacent connecting arc piece 206. A sliding piece 208 is integrally formed on the connecting arc piece 206 corresponding to the shape and size of the arc-shaped groove 207. The sliding pieces 208 are all securely and slidably fitted within the arc-shaped groove 207. The curvature of the arc-shaped groove 207 corresponds to the curvature of the supporting arc strip 205. This structure allows adjacent supporting arc strips 205 and connecting arc pieces 206 to slide and rotate relative to each other along the arc-shaped trajectory of the arc-shaped groove 207. When the entire continuous frame is subjected to external... When force is applied, the sliding piece 208 between each supporting arc strip 205 and the connecting arc piece 206 will slide and rotate adaptively along the arc groove 207 to adjust the relative angle between adjacent supporting arc strips 205 and connecting arc pieces 206. At the same time, the hinged connection between the four joints 204 and the side wall of the supporting window 202 provides a stable adjustment fulcrum, so that the entire series continuous skeleton can achieve adaptive adjustment of arch and arc through the dynamic deformation and relative displacement of each part, thereby adapting to the direction of external force or the shape requirements of the supported object.

[0055] Based on the aforementioned arch adjustment mechanism, the support arc strip 205 and the connecting arc plate 206 adopt an arc-shaped component-to-arc hinge method. This not only adapts to the differences in the curvature of local arc segments to achieve the adjustment of different support arches to meet the lying position positioning needs of special spinal patients, but also reduces the risk of pinching injury with a smaller adjustment angle compared to a horizontal hinge. Thus, the arch can be synergistically adjusted in a flexible and safe manner.

[0056] Regarding the drive for radius adjustment, specifically combined with... Figure 4 As shown, in this embodiment, an adjustment drive cavity 209 is provided inside the outer shell 201 at the position corresponding to the support window 202. The adjustment drive cavity 209 is provided with a plurality of contact-type camber adjustment components. Each contact-type camber adjustment component makes single-point contact with the bottom of the continuous frame. The contact-type camber adjustment components adjust the local camber of the chain arc frame by applying a telescopic support force to the corresponding contact point of the chain arc frame. Specifically, the number of contact-type camber adjustment components is odd and not less than 5 (this embodiment uses 5 contact-type camber adjustment components as an example). (1) (1) The design of an odd number of contact arch adjustment components ensures that there is a vertically supported contact arch adjustment component in the middle of the chain arc frame as the central reference anchor point for the arch adjustment of the entire continuous frame, which is adapted to the need for stable support of the core area in the spinal support scenario; (2) The design of no less than 5 contact arch adjustment components allows more adjustment points to be distributed in the support adjustment areas on both sides. Each adjustment point can apply stretching support force to a small local arc segment, which improves the accuracy of adaptation to the asymmetrical shape of the spine on both sides or the personalized lying position needs of different patients.

[0057] Specific examples Figure 4 As shown, each contact-type camber adjustment assembly includes a fixed base rod 210 and a hinged top rod 211. The fixed base rod 210 is welded into the adjustment drive cavity 209. An electrically controlled telescopic cylinder 212 is provided between the fixed base rod 210 and the hinged top rod 211. The bottom of the electrically controlled telescopic cylinder 212 is hinged to the fixed base rod 210, and the output shaft of the electrically controlled telescopic cylinder 212 is hinged to the hinged top rod 211. A controller is configured inside the housing 201, and the electrically controlled telescopic cylinders 212 are all signal-connected to the controller. Each hinged top rod 211 is provided with a contact arc plate 213, the curvature of which is consistent with the connecting rod 211. The arc of the contact plate 206 is the same; the telescopic action of each electrically controlled telescopic cylinder 212 drives the hinged top rod 211 to move up and down. The hinged structure between the hinged top rod 211 and the output shaft of the electrically controlled telescopic cylinder 212 enables it to drive the contact plate 213 to adapt to the overall angle change of the continuous frame. The matching of the arc of the contact plate 213 with the arc of the continuous frame can ensure the stability of single-point contact and reduce the stress concentration problem during camber adjustment. Each electrically controlled telescopic cylinder 212 independently applies different sizes of telescopic support force to the corresponding contact point to realize the adjustment of the local camber and the overall camber on the continuous frame.

[0058] The connection between the contact arc plate 213 and the hinged top rod 211 is a bearing-type rotating connection. This design allows the contact arc plate 213 to rotate flexibly with the sliding change of the contact point when the arch of the chain arc plate skeleton is adjusted. By converting the sliding friction at the contact point into rotational friction, the friction force is reduced, which not only ensures the smoothness of the arch adjustment process, but also reduces the wear between the contact arc plate 213 and the continuous skeleton as a whole, and adapts to the adjustment requirements of dynamic sliding of the contact point.

[0059] Furthermore, to achieve visualized adjustment and improve the accuracy and convenience of adjustment, this embodiment includes an auxiliary adjustment component on one side of the outer casing 201 for projecting a simulated image of the patient's spinal morphology. Specifically, in conjunction with... Figure 2 and Figure 6 As shown, the auxiliary adjustment component includes a sliding arm slidably connected to the side wall of the housing 201 (the sliding connection between the sliding arm and the housing 201 specifically includes: a groove 215 is provided on the housing 201, and the sliding arm is slidably connected within the groove 215). The sliding arm includes a collaborative robotic arm 214 with height and angle adjustment functions. The output end of the collaborative robotic arm 214 is fixedly connected to a projector 216, and the projector 216 is signal-connected to the controller. The controller acquires the patient's spinal scan image based on an external platform (such as a hospital's medical image archiving and communication system, a preoperative CT / MRI image workstation, or the image database of a surgical navigation system, etc.), and transmits the signal to the projector 216 to project the spinal scan image onto the patient's side. The height and angle of the projector 216 are flexibly adjusted by the collaborative robotic arm 214, and combined with the patient's spinal scan image transmitted by the controller and projected onto the patient's side, allowing the adjuster to intuitively compare the spinal image and adjust the camber, which improves the adjustment accuracy and simplifies the operation steps, effectively enhancing the convenience of the adjustment process.

[0060] The actuator of the collaborative robotic arm 214 is also equipped with a camera tracking device 217 for image locking and positioning with displacement tracking capabilities (referencing target detection technology based on YOLO series algorithms, DeepSORT or ByteTrack multi-target tracking algorithms, Kalman filter trajectory prediction technology, and visual servo combined with PID gimbal control technology, while also utilizing computer vision tool libraries such as OpenCV to achieve image locking and positioning and displacement tracking functions). The camera tracking device 217 is connected to the controller signal. Through image acquisition, locking, and tracking technology, the image of the spine projected onto the patient's side is locked and positioned and its displacement is tracked in real time. This improves the accuracy and real-time performance of the image reference during camber adjustment, and eliminates the need for frequent manual adjustments of the projector 216 by the operator to maintain stable image correspondence, effectively enhancing the convenience and operational efficiency of the adjustment process.

[0061] Example 2:

[0062] The difference between this embodiment and Embodiment 1 lies in the specific combination... Figure 1 and Figure 7 As shown, the actuator of the collaborative robotic arm 214 is also equipped with an ultrasonic suspension assembly 3. The ultrasonic suspension assembly 3 includes a positioning platform 301 fixedly connected to the collaborative robotic arm 214. A wire hanging shell 302 is welded onto the positioning platform 301. A wire take-up device 303 is installed inside the wire hanging shell 302. The wire take-up device 303 includes a wire take-up housing rotatably connected to the positioning platform 301. A torsion spring is provided inside the wire take-up housing. One end of the torsion spring is fixedly connected to the inner side wall of the wire take-up housing, and the other end of the torsion spring is fixedly connected to the positioning platform 301. A traction wire 304 is fixedly connected to the outer side wall of the wire take-up housing. A retainer 305 is fixedly connected to the end of the traction wire 304 away from the wire take-up housing (the retainer 305 is used to clamp and fix the ultrasonic probe to be used in the operation). The hanging shell 302 has a cable inlet groove 306 (for the connection cable of the ultrasound probe to pass through). This design allows the ultrasound probe to be fixed in the holder 305 before surgery. When the ultrasound probe is needed during surgery, medical staff only need to hold the holder 305 and the ultrasound probe to perform free probe operation. When other surgical operations are required, the torsion spring in the cable retractor 303 will drive the cable retractor shell to rotate and retract the traction cable 304, so that the ultrasound probe will elastically retract to the positioning table 301 under the action of the holder 305. This reduces the probability of contamination or damage caused by random placement of the ultrasound probe and ensures that it can be quickly retrieved when needed later, improving the convenience and standardization of pain management surgical operations.

[0063] Furthermore, a unique feature is that, because the collaborative robotic arm 214 in this solution can always align the camera tracking component 217 with the patient's side, the positioning stage 301 will always be located close to the patient's side. This ensures that the positioning stage 301 integrated into the execution end of the collaborative robotic arm 214 is always in the optimal deployment position close to the patient's side, ensuring that the ultrasound probe to be used during the operation is always in an ergonomically designed position that is easy for medical staff to access. Compared with the traditional fixed positioning stage 301, this dynamic adaptation design completely breaks the spatial limitations of the fixed layout, reducing the risk of surgical operation interference that may exist in a fixed position, shortening the operation path for medical staff to access the ultrasound probe, and improving the continuity and efficiency of the pain management surgical process.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
