Description

Technical Field

[0001] This utility model relates to the field of esophageal tumor surgical facilities, specifically an intraoperative positioning assistance device. Background Technology

[0002] For the treatment of esophageal tumors, surgical resection is the ultimate treatment. Depending on the location and condition of the tumor, this surgery is likely to be one of the most complex surgeries performed in the department. While some esophageal cancer surgeries can be performed minimally invasively, some complex cases still require traditional incision methods. Because the surgery involves the treatment of multiple tissues in the abdomen, chest, and neck, the surgical positioning has undergone a long process of evolution and change along with advancements in surgical techniques.

[0003] Traditional three-incision or two-incision cervicothoracic-abdominal surgery is a classic and standard surgical approach, especially common in medical centers with long-standing and experienced practices. The surgery employs a phased approach, alternating between the supine (neck and abdomen) and lateral (chest) positions. The supine position is the most classic and comfortable position for abdominal and cervical surgery, providing ample exposure and ease of manipulation. In this position, the stomach can be dissected and a tubular stomach created; sometimes, the cervical esophagus can also be dissected to prepare the anastomosis site. The lateral position is also necessary for dissecting the thoracic esophagus, removing tumors, clearing lymph nodes, and finally elevating the tubular stomach to the neck for anastomosis, providing ideal exposure of the surgical field for the corresponding areas.

[0004] For over a decade, minimally invasive surgery has used the left lateral decubitus position (left lateral decubitus position + semi-supine position) in its application to esophageal cancer surgery. However, with the accumulation of experience in minimally invasive surgery, based on the requirements for surgical quality and precision, many doctors have also begun to try to adjust the body position. For example, Professor Palanivelu, an Indian physician, reported on more than 100 mature experiences of thoracoscopic esophagectomy in 2006, which also required changes in the body position angle during the operation.

[0005] In existing operating rooms, changes in patient positioning, often using standard operating tables, rely heavily on manual assistance. This carries the risk of the patient turning over during repositioning, places a strain on the surgeon's physical strength, and is time-consuming, thus extending the surgical duration. A few institutions have introduced operating tables that can rotate laterally, but these require multiple restraints on both sides of the patient's body to keep them still during rotation. Even with these, certain risks remain, and the risks increase dramatically for heavier or larger patients, rendering them unsuitable. Utility Model Content

[0006] The purpose of this invention is to provide an intraoperative positioning assistance device that can assist in changing and supporting the patient's position during surgery. It is simple to operate and safe in the process.

[0007] To achieve the above objectives, this utility model employs the following technical solution: An intraoperative positioning assist device includes a main beam arranged along the width of the operating table during use. The two ends of the main beam are respectively provided with baffles located on both sides of the operating table. A fixing plate is fixed in the middle of the main beam. A support plate and a drive plate are respectively arranged on both sides of the fixing plate. The side of the drive plate away from the fixing plate has a linear travel relative to the length direction of the main beam. The drive plate is hinged to the side adjacent to the support plate. The side of the support plate close to the fixing plate is hinged to the outer side of the main beam or the fixing plate.

[0008] The main beam has symmetrically arranged side beams of equal length on both sides, and the fixing plate is also fixed on the top surface of the side beams. The outer end of the side beams is fixedly connected to the top side of the baffle.

[0009] The main beam and side beam are provided with threaded grooves, and the fixing plate has multiple countersunk holes through which bolts that mate with the threaded grooves are inserted.

[0010] The support plate has a clearance groove on the side closest to the fixed plate, corresponding to the position of the main beam and the side beam.

[0011] An installation shaft is provided between the side beam and the main beam. The installation shaft is located near both sides of the fixing plate and is symmetrically arranged. The side of the support plate near the fixing plate is hinged to the installation shaft.

[0012] The support plate and the drive plate have the same width.

[0013] A sliding plate is provided on the side of the drive plate near the baffle. The sliding plate is hinged to the side of the drive plate adjacent to it. The sliding plate is located above the main beam and is slidably connected to the main beam along the length of the main beam. A stroke groove is provided in the middle of the main beam near the baffle. A screw rod is provided in the center of the stroke groove and is rotatably connected to the main beam. A threaded sleeve is threadedly connected to the screw rod and fixed to the bottom surface of the sliding plate.

[0014] The main beam is provided with sliding grooves on both sides, and the sliding plate is provided with sliding rulers on both sides that are slidably connected in the sliding grooves. The sliding rulers located on both sides of the sliding plate extend relative to each other.

[0015] The screw has a handle at its outer end.

[0016] A stepper motor is mounted on the baffle, and the output shaft of the stepper motor is connected to the outer end of the screw via a reducer.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this device in conjunction with surgery, simply place it directly on the operating table. The spacing between the side panels adapts to the width of the table, allowing for immediate and effective coordination. The device boasts a simple structure, easy control, and intuitive operation. To support the body on the desired side, simply adjust the angle of the support plate and drive plate closest to that side. The symmetrical structure allows for flexible selection of the side to be supported as needed, and it adapts to potential tilt changes during surgery. Compared to changing the angle of the table, it provides safer support for the patient, is simpler to operate (eliminating the need for various support blocks), and is also more cost-effective.

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0025] Unless otherwise specified, the instruments, reagents, and materials used in the following embodiments are all conventional instruments, reagents, and materials already available in the prior art and can be obtained through legitimate commercial channels. Unless otherwise specified, the experimental methods and detection methods used in the following embodiments are all conventional experimental methods and detection methods already available in the prior art.

[0026] Example:

[0027] This example is primarily used in conjunction with the operating table to assist and support the patient's positioning during surgery.

[0028] The main structure of this device includes a main beam 1 extending laterally along the operating table. Baffles 3 are fixed at both ends of the main beam 1. The baffles 3 are located on both sides of the operating table. Side beams 2 of equal length and parallel to the main beam 1 are provided on both sides of the main beam 1. There are two side beams 2 arranged in parallel. The two ends of the side beams 2 are also fixed to the baffles 3. The main beam 1, side beams 2 and baffles 3 form a door-shaped structure, which can be directly placed laterally along the surgical wound to achieve rapid coordination with the operating table.

[0029] The main beam 1 is wider, two to three times wider than the side beam 2, because the main beam 1 is also used to coordinate with other mechanisms, while the side beam 2 is used to improve the support capacity of the entire structure and ensure the stability of the entire structure.

[0030] A fixing plate 4 is bolted to the upper center of the main beam 1. Multiple countersunk holes 5 are drilled through the fixing plate 4, and bolts pass through these holes. Threaded grooves are provided in the middle of the main beam 1 and the middle of the side beam 2, which cooperate with the bolts to secure the fixing plate 4. This facilitates disassembly, replacement, and other maintenance of the fixing plate 4. The fixing plate 4 has ramps on both sides to reduce discomfort caused by the drop in elevation. Alternatively, the ramps can be omitted, and medical drapes can be placed on both sides for added comfort.

[0031] The fixed plate 4 is provided with a support plate 6, a drive plate 7, and a sliding plate 8 on both sides respectively.

[0032] The support plate 6 and the drive plate 7 have the same width.

[0033] The lengths of the support plate 6, drive plate 7, and fixing plate 4 are adapted to each other.

[0034] An installation shaft 9 is provided between the main beam 1 and the side beam 2. The installation shaft 9 is located near both sides of the fixing plate 4 and is symmetrically arranged. The side of the support plate 6 near the fixing plate 4 is hinged to the installation shaft 9. The side of the support plate 6 near the installation shaft 9 is provided with a clearance groove corresponding to the position of the main beam 1 and the side beam 2, so as to make room for the interference area when the support plate 6 is flipped upward.

[0035] The support plate 6 and the drive plate 7 are hinged to each other on the adjacent side, forming a hinge-like structure. The hinge of the support plate 6 and the drive plate 7 forms a variable-angle "^" shaped triangular structure, with the triangular protrusion changing upwards.

[0036] The sliding plate 8 is disposed between the drive plate 7 and the baffle 3, and has a sliding stroke along the length of the main beam 1 between the drive plate 7 and the baffle 3 on the outer side. Its specific structure is as follows: a stroke groove 10 is provided in the middle of the side of the main beam 1 near the baffle 3; a screw 11 is rotatably connected to the main beam 1 in the center of the stroke groove 10; a threaded sleeve 12 is threadedly connected to the screw 11; sliding grooves 13 are provided on both sides of the main beam 1; and sliding rulers 14 are slidably connected in the sliding grooves 13 on both sides of the sliding plate 8. The sliding rulers 14 on both sides of the sliding plate 8 extend relative to each other, constraining the mutual clamping and sliding of the two sides of the main beam 1. The bottom surface of the sliding plate 8 is fixedly connected to the threaded sleeve 12, so that the position of the sliding plate 8 relative to the main beam 1 can be driven by the rotation of the screw 11.

[0037] The sliding plate 8 has a rotating shaft at each end, and the drive plate 7 has a rotating seat on the outside corresponding to the rotating shaft, which is rotatably connected to it, so as to realize the hinge between the outside of the drive plate 7 and the sliding plate 8. By sliding the sliding plate 8 laterally along the bed, the angle of the support plate 6 swinging upward can be changed.

[0038] When the top surfaces of the support plate 6, drive plate 7, and fixed plate 4 are coplanar, the support plate 6, drive plate 7, and sliding plate 8 are arranged side by side with the sliding plate 8 close to the baffle 3. When the sliding plate 8 slides towards the fixed plate 4, it pushes the hinge of the drive plate 7 and support plate 6 inward to arch upward, forming a triangular support. This provides support to the patient on one side and causes a change in body position. Because the triangular support is stable, the support plate 6 has a wider contact with the patient's body side in the front-back direction, and the height and angle of the lift can be precisely controlled by rotating the screw 11. Therefore, the accuracy of the support and body position assistance is higher and safer.

[0039] Compared to existing systems that can only provide localized support using pads or airbags, this long strip provides support over a wider range, extending beyond easily deformable areas such as joints, ensuring the stability of the body's posture during lifting or flipping.

[0040] By using the hinged changes of the triangle, the support plate 6 supports one side of the body, making the structure more stable. The width of the support plate 6 does not obstruct the surgical area, and the side is fully exposed.

[0041] The baffle 3 is provided with a mounting seat 15 in the middle for rotating the mounting screw 11 and allowing the outer end of the screw 11 to pass through. The outer end of the screw 11 is provided with a handle 16 for easy control of the screw 11.

[0042] Not limited to this example, an electric control method can also be used. For example, a stepper motor can be installed below the baffle 3. The output shaft of the stepper motor and the outer end of the screw 11 can be electrically driven to rotate the screw 11 through gear transmission or belt transmission.

[0043] When using this device to assist in surgery, it is placed directly on the operating table. The distance between the side panels 3 is adapted to the width of the bed, allowing for immediate and effective coordination. The support plates 6, with their symmetrical structure, are controlled according to the initial position and intraoperative changes. In conjunction with traditional surgical procedures, if a three-incision thoracoabdominal approach is used, the patient initially lies supine with the support plates 6 horizontal. When the patient needs to change to a lateral decubitus position during surgery, the support plate 6 located on the back side is raised, thus providing even support to the patient's back and assisting in changing position.

[0044] Other changes in body position can be made as needed.

[0045] This device features a simple structure, easy control, and intuitive operation. To support the body on the desired side, the support plate 6 and drive plate 7 on the side closest to that side adjust the angle of the triangular support. The symmetrical structure allows for flexible selection of the side to be supported as needed, and it adapts to potential tilt changes during surgery. Compared to changing the angle of the bed, it provides safer support for the patient, is simpler to operate (eliminating the need for various support blocks), and is also less expensive.
