Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more particularly to a multi-degree-of-freedom surgical posture adjustment device. Background Art

[0002] In the delicate and complex medical process of surgery, the patient's position is not a simple placement, but a key factor affecting the overall success of the operation. The human anatomy is complex and diverse, and the various surgical sites are hidden deep in the body and are often adjacent to important blood vessels, nerves and organs. Only by adjusting the patient to the appropriate surgical position can the surgical site be accurately exposed, creating a clear and open operating field of view for the doctor.

[0003] In response to this technical problem, the Chinese patent with authorization announcement number (application number) 202222019473.9 discloses an electric operating bed with multi-degree-of-freedom adjustment. The utility model provides an electric operating bed with multi-degree-of-freedom adjustment, and the leg support assembly includes a support bent rod, a telescopic adjustment rod 1, a footrest, a calf frame and a thigh frame. The upper end of the support bent rod is hinged with a calf frame, and the left end of the calf frame is hinged with a footrest. Compared with the prior art, the utility model has the following beneficial effects: by setting an electric telescopic rod 1 and an electric telescopic rod 2, in conjunction with the head bed board and the leg bed board, the two ends of the entire bed body can be adjusted in height, which is convenient for use. The arm placement board is set so that the patient's arms can be adjusted in angle according to actual needs, making the patient more comfortable and facilitating the operation. The design of the leg support assembly enables the patient's feet, calves and thighs to be adjusted separately at different placement angles, ensuring that the patient's legs will not be displaced, which is conducive to the operation. Multiple freely adjustable structures ensure the patient's comfort. Most existing surgical position adjustment devices can only achieve simple lifting, left and right translation or rotation functions, and cannot meet the needs of multi-dimensional and precise adjustment of patient positions in complex operations. In some spinal surgeries, neurosurgeries and other surgeries that require extremely high operating fields and angles, traditional position adjustment devices are difficult to provide sufficient degrees of freedom to achieve the ideal surgical position, which makes it inconvenient for doctors to operate and increases the risk and difficulty of surgery.

[0004] Therefore, a multi-degree-of-freedom surgical position adjustment device is proposed. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a multi-degree-of-freedom surgical position adjustment device that can achieve.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Example 1:

[0034] See also Figures 1 to 3 A multi-degree-of-freedom surgical position adjustment device includes a fixed base 1, a guide groove 101 is provided on the upper surface of the fixed base 1, and a sliding seat 102 is slidably installed on the inner surface of the guide groove 101. This technical solution, through the setting of the guide groove 101, can limit the sliding direction of the sliding seat 102, thereby preventing the electric lifter 2 from offsetting during the displacement process, causing the electric lifter 2 to tilt and affecting the position of the operating table 210.

[0035] An electric lifter 2 is provided on the upper surface of the sliding seat 102, and a rotating bearing 201 is rotatably installed on the upper end surface of the electric lifter 2, and a transmission gear 202 is provided on the upper surface of the rotating bearing 201. This technical solution, through the setting of the rotating bearing 201, can drive the rotating bearing 201 to rotate by engaging the transmission gear 202 with the driving gear 205, thereby completing the angle adjustment of the operating table 210.

[0036] A support plate 206 is provided on the upper surface of the transmission gear 202, and expansion plates 207 are slidably installed on the two side surfaces of the support plate 206. This technical solution, through the setting of the expansion plate 207, can increase or decrease the length of the support plate 206 by sliding along the support plate 206 to extend or retract it, so that the length of the support plate 206 can be adjusted according to the length of the operating bed 210, so that it can better cooperate with the operating bed 210, thereby improving the adaptability of the support plate 206.

[0037] Electric lifters 208 are installed on both sides of the upper surface of the expansion plate 207, and a universal ball head 209 is provided at the upper end of the electric lifter 208. This technical solution, through the setting of the electric lifter 208, can be used to raise and lower the height of the electric lifter 208 on one side separately, and then rotated in coordination with the universal ball head 209 to adjust the position of the operating table 210 to assist the doctor in performing the operation.

[0038] A rotating sleeve 4 is installed on the outer surface of the universal ball head 209, and an operating table 210 is provided on the upper surface of the rotating sleeve 4. This technical solution realizes the precise adjustment of the operating table 210 in height, horizontal position, pitch, roll, rotation and other degrees of freedom. It can meet the precise control of the patient's body position for different types of surgery, provide doctors with a more ideal surgical operation perspective and space, make the operation more convenient during the operation, and improve the convenience and success rate of the operation.

[0039] A limit ring 203 is provided on the outer surface of the upper end of the electric lifter 2, and a servo motor 204 is provided on the upper surface of the limit ring 203. A driving gear 205 is provided at the output end of the servo motor 204, and the driving gear 205 is arranged to be meshed with the transmission gear 202. This technical solution, through the setting of the limit ring 203, can support the servo motor 204 while also protecting the servo motor 204, the rotating bearing 201 and the transmission gear 202 when the height of the electric lifter 2 is lowered to avoid interference between them and the electric lifter 2.

[0040] Figures 4 to 6As shown, a threaded drive rod 3 is rotatably mounted at the bottom of the guide slot 101, and a helical connection is provided between the threaded drive rod 3 and the sliding seat 102. This technical solution, through the provision of the threaded drive rod 3, can drive the sliding seat 102 along the guide slot 101 through helical transmission, thereby adjusting the displacement of the operating table 210. Furthermore, during the adjustment of the operating table 210 by the multi-angle adjustment assembly, the stability of the operating table 210 during vertical and horizontal movement is ensured by means of position limiting and supporting means, reducing risks during surgery and improving the safety and reliability of the device.

[0041] Support blocks 301 are provided on both sides of the upper surface of the support plate 206, and a bidirectional spiral transmission rod 302 is rotatably installed on the inner surface of the support block 301, and a sliding push rod 303 is spirally installed on the outer surface of the bidirectional spiral transmission rod 302, and the end of the sliding push rod 303 is set to be fixedly connected to the upper surface of the end of the expansion plate 207. This technical solution can drive the sliding push rod 303 by spiral transmission according to the age and weight of the patient, and extend or retract the expansion plate 207 from the inside of the support plate 206, so as to facilitate the electric lifter 208 with a universal ball head 209 to position and adjust different models of operating tables 210, so that different models of operating tables 210 can be used, which is convenient for doctors to perform operations on patients and maximize the safety and comfort of surgery.

[0042] The surface of the sliding push rod 303 slides through the limited slide rod 304, and the two ends of the limited slide rod 304 are fixedly installed on the inner surface of the support block 301. This technical solution, through the setting of the limited slide rod 304, can limit the sliding push rod 303 by sliding limitation during the displacement of the sliding push rod 303, thereby preventing the sliding push rod 303 from flipping and dislocating during the movement process.

[0043] Figures 7 and 8 As shown, the upper surface of the operating table 210 is provided with a plurality of limiting chutes 401, and the lower surface of the limiting chutes 401 is provided with a support frame 402. An air pump 406 is provided in the middle of the upper surface of the support frame 402, and an air tube 407 is installed on the upper surface of the air pump 406. This technical solution, through the provision of the air pump 406, can accurately deliver air pressure to the inflatable airbag 405 inside each limiting chute 401 through servo control, ensuring that each inflatable airbag 405 has a different hardness, so that it can better fit the patient's skin surface, further improving the comfort during surgery.

[0044] Electric lifters 3 403 are installed on both sides of the upper surface of the support frame 402, and a sliding plate 404 is provided on the upper surface of the electric lifter 3 403, and a sliding connection is set between the sliding plate 404 and the inner surface of the limiting slide 401. This technical solution, through the setting of the electric lifter 3 403, can drive the sliding plate 404 to slide along the limiting slide 401 according to the use requirements to adjust the height of the inflatable airbag 405, which can improve the patient's comfort while improving the stability of the operating bed 210 during tilt and height adjustment.

[0045] An inflatable airbag 405 is installed on the upper surface of the sliding plate 404, and an inflatable tube 407 passes through the sliding plate 404 and is connected to the inflatable airbag 405. This technical solution, through the provision of the inflatable tube 407, can control the air pump 406 to accurately send air pressure into the interior of the inflatable airbag 405 through the inflatable tube 407 when it is necessary to adjust the hardness of the inflatable airbag 405 in a floating manner. By providing the inflatable airbag 405, the inflatable airbag 405 can be inflated by the air pump 406 during surgery to provide floating support for the patient's head, waist and legs. This can improve the patient's comfort during surgery through support, and can also adjust the hardness and height of the inflatable airbag 405 according to the doctor's surgical needs to facilitate the doctor's surgical operation.

[0046] Instructions for use: Before surgery, the operating table 210 of appropriate size is rotated according to the patient's body shape and weight. After the selection is completed, the bidirectional spiral transmission rod 302 is started to rotate to control the sliding push rod 303 installed on its outer surface. After the sliding limit of the limit slide rod 304, the sliding push rod 303 is driven to spread outward to drive the expansion plate 207 to slide out from the inside of the support plate 206. After adjusting the overall height of the support plate 206, the operating table 210 with the rotating sleeve 4 is accurately installed on the upper surface of the electric lifter 208 with the universal ball head 209 by plugging. After the installation is completed, the posture and height of the operating table 210 can be adjusted. First, start the electric lifter 2 to drive the support plate 206 to move upward to complete the height adjustment of the operating table 210, and then start the servo installed on the upper surface of the limit ring 203. The motor 204 drives the driving gear 205 to rotate and mesh with the transmission gear 202, thereby driving the transmission gear 202 to make the rotating bearing 201 continue to rotate to adjust the angle of the operating table 210. Finally, the control threaded transmission rod 3 is started, and by rotating at the bottom of the guide slide 101, the sliding seat 102 is pushed to slide along the guide slide 101 through the spiral transmission method, so that the operating table 210 is close to the doctor's position for convenient surgical operations. After completing a series of adjustments, the operation can be performed. During the operation, if the patient's position needs to be tilted, the electric lifter 208 can be directly started. By separately controlling the height of the electric lifter 208 on one side, the height difference is utilized to make the universal ball head 209 rotate frictionally inside the rotating sleeve 4, thereby controlling the operating table 210 to tilt, so as to facilitate the doctor's surgical operations. When the operating bed 210 is tilted, in order to ensure the patient's comfort and the installation of the surgical operation, the electric lifter 3 403 can be started synchronously to push the sliding plate 404 to slide along the inner surface of the limiting slide 401, and control the height of the inflatable airbag 405. At the same time, the air pump 406 is started to pump air into the interior of the inflatable airbag 405 through the inflation tube 407, and the softness and hardness of the inflatable airbag 405 are adjusted to improve the patient's comfort while improving the safety of the operation.
