Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a surgical bed for pelvic and hip joint surgery. Background Technology

[0002] In orthopedic clinical treatment, traditional operating tables have many limitations in these types of surgeries: the angle adjustment of the bed board mostly relies on manual operation, or cannot be adjusted at all, and the adjustment range is limited, which cannot meet the positional needs of different patients and affects the surgical field of vision; the traction mechanism is rudimentary in design, mostly providing fixed-direction traction, and cannot flexibly adjust the traction angle and force according to the needs of the surgery, making it difficult to achieve individualized traction plans and increasing the difficulty of surgical reduction.

[0003] Furthermore, traditional operating tables typically employ a single, fixed traction structure, which is inconvenient to assemble and disassemble, hindering rapid intraoperative adjustments. Additionally, most operating tables lack automated control functions, relying on manual operation by medical staff, increasing workload and making it difficult to ensure consistent adjustment precision. These problems severely restrict the smooth execution of pelvic and acetabular surgeries and negatively impact postoperative recovery. Therefore, developing a specialized operating table for pelvic and acetabular surgeries with precise adjustment and flexible traction has become an urgent need in orthopedic clinical practice.

[0033] 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.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0036] Example

[0037] This embodiment provides a surgical bed for pelvic and acetabular surgery, including: a bed body 1, two traction mechanisms 2, two adjustment mechanisms 3, and two traction belts 4;

[0038] The bed body 1 includes a bed frame 11, a support mechanism 12, a first bed board 13, and a second bed board 14. The support mechanism 12 provides stable support for the entire bed body, while the first bed board 13 and the second bed board 14 provide lying space for the patient and can be adjusted according to needs.

[0039] The support mechanism 12 is fixedly installed at the bottom of the bed frame 11. The first bed board 13 and the second bed board 14 are arranged sequentially along the length of the bed frame 11, and the tail end of the first bed board 13 is rotatably connected to the bed frame 11 near the middle. The support mechanism 12 provides support from the bottom of the bed frame 11 to ensure the overall stability of the bed. The rotatable connection design at the tail end of the first bed board 13 provides a basis for its angle adjustment, making it convenient to adapt to different lying needs of patients.

[0040] The head end of the bed frame 11 is fixedly provided with a traction belt connecting frame 5, and the two sides of the bed frame 11 are provided with through-slide grooves 111 at the second bed board 14. The traction belt connecting frame 5 is used to connect the traction belt 4 and provide a fixed point for traction. The through-slide grooves 111 provide a path for the sliding of the connecting piece 22 in the traction mechanism 2.

[0041] Two adjustment mechanisms 3 are fixedly and spaced apart on the bottom of both sides of the bed frame 11. The output end of the adjustment mechanism 3 is hinged to the bottom of the first bed board 13. The adjustment mechanism 3 can drive the first bed board 13 to rotate around the rotating connection, thereby adjusting the angle of the first bed board 13 to meet the different positional needs of the patient and improve the patient's lying comfort.

[0042] Two traction mechanisms 2 are fixedly installed on both sides of the bed frame 11; the traction mechanisms 2 on both sides can pull the patient in the same direction to ensure the balance and effectiveness of traction and meet different traction needs during surgery.

[0043] The traction mechanism 2 includes: a first electric push rod 21, a connector 22, a rotating traction rod 23, a traction belt connecting rod 24, and a rotating motor 25; these components work together to adjust the traction direction and position, providing precise control for traction operations during surgery.

[0044] The first electric push rod 21 is fixedly mounted on one side of the bed frame 11. The output end of the first electric push rod 21 is fixedly connected to one side of the connector 22, which is slidably mounted in the slide groove 111 of the bed frame 11. The first electric push rod 21 provides power for the sliding of the connector 22, enabling it to move along the slide groove 111, thereby driving subsequent components to adjust their positions to meet different traction position requirements. Furthermore, the first electric push rod 21 is connected to an automation controller, which controls its movement. Medical personnel can precisely control the extension and retraction of the output end of the first electric push rod 21 through the automation controller, thereby accurately adjusting the sliding distance of the connector 22.

[0045] One side of the rotating traction rod 23 is rotatably mounted on the upper part of the connecting member 22. This side is fixedly connected to the output end of the rotating motor 25, which is also fixedly mounted within the connecting member 22. The rotating motor 25 is a servo motor with a motor brake, enabling precise rotation of the rotating traction rod 23 to change the traction direction and adapt to different traction angle requirements during surgery. The rotating motor 25 is connected to an automation controller, which controls its angle and locks the angle of the rotating traction rod 23. Specifically, when the automation controller controls the rotating motor 25 to rotate the rotating traction rod 23 to the desired angle, the controller sends a stop command to the motor 25. At this point, the motor brake engages, tightly gripping the motor shaft and preventing it from rotating, thus locking the angle of the rotating traction rod 23. This locking method ensures that the rotating traction rod 23 will not rotate unexpectedly due to external forces during traction, guaranteeing the stability and accuracy of the traction.

[0046] The traction belt connecting rod 24 is fixedly disposed on the other side of the rotating traction rod 23; the traction belt connecting rod 24 is used to connect the traction belt 4, and transmit the rotation and movement of the rotating traction rod 23 to the traction belt 4 to achieve effective traction on the patient.

[0047] The traction ends of the two traction belts 4 are fixedly connected to the traction belt connecting frame 5 and the traction belt connecting rod 24, respectively. The traction belts 4 are connected to the traction belt connecting frame 5 and the traction belt connecting rod 24. Through the action of the traction mechanism 2, the patient is pulled to help complete the repositioning and other operations during the operation.

[0048] The adjustment mechanism 3 includes a second electric push rod 31, a fulcrum connecting rod 32, and two adjusting rods 33. These components form a lever structure, which can efficiently drive the first bed board 13 to adjust the angle, making the operation convenient and stable.

[0049] The second electric actuator 31 is fixedly mounted at the bottom of the bed frame 11, with its output end extending downwards. A fulcrum connecting rod 32 is fixedly mounted on the upper side of the support mechanism 12. The second electric actuator 31 provides power, and the fulcrum connecting rod 32 acts as a lever fulcrum, ensuring the stable rotation of the adjusting rod 33. The second electric actuator 31 is connected to an automation controller, which controls its extension and retraction. Medical personnel can use the automation controller to precisely adjust the angle of the first bed board 13 by controlling the extension and retraction of the output end of the second electric actuator 31.

[0050] One end of the adjusting rod 33 is hinged to the output end of the second electric push rod 31, and the other end of the adjusting rod 33 is hinged to the bottom of the first bed board 13. The middle part is hinged to the fulcrum connecting rod 32 to form a lever structure. The design of the lever structure enables the power of the second electric push rod 31 to be transmitted to the first bed board 13 more efficiently, so as to achieve flexible adjustment of the angle.

[0051] Among them, the adjusting rod 33 is S-shaped; the S-shaped design allows the adjusting rod 33 to better avoid other components during rotation, reducing spatial interference, and also enhancing its structural strength.

[0052] Among them, "T"-shaped sliding limiters 221 are fixedly provided on both sides of the bottom of the connector 22, and the side wall of the slide groove 111 is provided with a sliding limit groove that matches the shape of the "T"-shaped sliding limiter 221; the "T"-shaped sliding limiter 221 cooperates with the sliding limit groove to limit the sliding direction of the connector 22, prevent it from deviating or shaking during the sliding process, and ensure the stability of the traction mechanism 2.

[0053] The traction belt 4 includes two parallel traction fixation belts 41 and several elastic fixation belts 42 spaced apart and perpendicularly connected between the two traction fixation belts 41 along the length of the traction fixation belts 41. This structure allows the traction belt 4 to provide stable traction force and to better fit the patient's body through the elastic fixation belts 42.

[0054] The ends of several elastic fixation straps 42 are fixedly provided with quick-release buckles 43; the quick-release buckles 43 facilitate the quick installation and removal of the traction straps 4, saving time for surgical preparation and postoperative care.

[0055] The traction belt connecting frame 5 and the traction belt connecting rod 24 are both provided with traction belt connecting grooves 6 on one side. The connecting end of the traction fixing belt 41 is detachably set in the traction belt connecting groove 6. The traction belt connecting groove 6 provides a stable connection position for the traction belt 4, and the detachable design makes it easy to replace traction belts 4 of different specifications.

[0056] The second bed board 14 is a perforated board; the perforated board design reduces the weight of the bed board and facilitates the installation of auxiliary equipment.

[0057] Among them, a lockable caster wheel 121 is fixedly installed at each of the four corners of the bottom of the support mechanism 12; the lockable caster wheel 121 facilitates the movement of the bed, and locking it during surgery can ensure the stability of the bed and increase the flexibility of the bed.

[0058] In one preferred embodiment, several positioning holes 131 are evenly distributed along the length direction on both sides of the first bed board 13, and the limiting rod 132 is detachably installed in the holes; when the limiting rod 132 is placed under the patient's armpits on both sides, and the traction belt connecting rod 24 pulls the traction belt 4, the limiting rod 132 forms an armpit support, thereby fixing the patient in sequence.

[0059] In use, first unlock the lockable casters 121, push the bed to the appropriate position, and then lock them. The patient lies on the operating table, and by operating the automatic controller, controls the extension and retraction of the second electric push rod 31 of the adjustment mechanism 3, driving the adjustment rod 33 to rotate around the fulcrum connecting rod 32, adjusting the first bed board 13 to the appropriate angle; then fix the two traction belts 4. The elastic fixing strap 42 of one traction belt 4 is fixed to the patient's upper limb through the quick-release buckle 43, and the connecting end of the traction fixing strap 41 of this traction belt 4 is detachably set in the connecting groove 6 of the traction belt connecting frame 5; the elastic fixing strap 42 of the other traction belt 4 is fixed to the patient's lower limb through the quick-release buckle 43, and the connecting end of the traction fixing strap 41 of this traction belt 4 is detachably set in the connecting groove 6 of the traction belt connecting rod 24, ensuring that both traction belts 4 fit the corresponding parts of the patient's body.

[0060] As needed, the first electric push rod 21 of the traction mechanism 2 is activated via the automated controller, pushing the connecting piece 22 to slide along the slide groove 111. The "T"-shaped sliding limit piece 221 ensures stable sliding, adjusting the traction position. The automated controller then controls the rotating motor 25, causing the rotating traction rod 23 to rotate to the desired angle. The automated controller then sends a stop command to the rotating motor 25, triggering its brake to lock the angle of the rotating traction rod 23. The traction belt 4 then applies corresponding traction to the patient's upper and lower limbs. If the angle of the patient's upper body needs adjustment, the adjustment mechanism 3 can be operated again via the automated controller.

[0061] In summary, the pelvic and acetabular surgical bed of this invention, through the coordinated operation of its various components, can flexibly adjust the angle of the bed board and the direction and position of traction, providing a stable and convenient operating platform for pelvic and acetabular surgery. It effectively solves the problems of inconvenient adjustment of traction angle and position of existing surgical beds, helps to improve surgical efficiency and safety, and has important clinical application value.

Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of this utility model should be included within the protection scope of this utility model.
