Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a six-joint, multi-angle, retractable, and lockable outrigger. Background Technology

[0002] A medical outrigger is a support system used for medical equipment, commonly found in operating rooms, ICUs, and other medical environments. It is used to fix and support medical equipment such as surgical lights, main devices, imaging equipment, and anesthesia equipment. During surgery or patient monitoring, doctors can use the medical outrigger to move equipment or adjust its angle for better observation and operation. To facilitate operation by medical staff, existing outriggers need to have adjustable functions for height, angle, and rotation direction. However, due to considerations of load-bearing capacity and stability, existing outriggers typically have a limited number of joints, resulting in limited adjustment of rotation and pitch angles.

[0003] In practical medical applications, different surgical scenarios and needs place varying requirements on the extension range and load-bearing capacity of outriggers. However, existing outriggers, due to considerations of load-bearing capacity and stability, typically have a limited number of joints, resulting in limited adjustment of rotation and pitch angles and relatively poor flexibility. Increasing the number of joints directly on top of the existing design would significantly reduce the stability of the medical device, making it prone to interference during joint adjustments and rotation, thus degrading the user experience and even affecting the surgery. Therefore, current practices typically involve designing specific medical outriggers for specific surgical scenarios and needs, lacking universal multi-joint outriggers suitable for different surgical scenarios. Furthermore, outriggers are prone to loosening during storage and refurbishment, occupying considerable space and easily damaged by impacts, affecting their usability. Therefore, there is a need to design a multi-joint outrigger that, while ensuring effective support, allows for flexible multi-angle adjustment of each joint and can be stowed and locked. Summary of the Invention

[0004] This invention addresses the problems of existing medical outriggers having a small number of joints, poor adjustment flexibility, inability to simultaneously achieve load-bearing stability and adjustment flexibility, and susceptibility to damage during storage. It proposes a six-joint, multi-angle, retractable and lockable outrigger.

[0005] Existing outriggers have a limited number of joints, poor adaptability to different surgical scenarios and needs, low flexibility, and are unable to be locked and stored. Therefore, a six-joint, multi-angle, retractable and lockable outrigger is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A six-joint, multi-angle, retractable, and lockable support arm includes a base, a lower support arm, a support arm connector, an upper support arm, a lower column connector, an upper column connector, a rotating column, a rotating connector, an equipment mounting base, a storage handle, and storage components.

[0008] The bottom end of the base is the mounting end, and the top end of the base is fitted with the bottom end of the lower support arm to form a first limiting joint. The first limiting joint is used to allow the lower support arm to rotate axially left and right relative to the base and to limit the rotation angle range of the lower support arm.

[0009] The top end of the lower support arm is fitted with the support arm connector to form a second limiting joint. The second limiting joint is used to allow the support arm connector to rotate axially to the left and right relative to the lower support arm and to limit the rotation angle range of the support arm connector.

[0010] The side of the outrigger connector is connected to the bottom of the upper outrigger to form a third limiting joint. The third limiting joint is used to allow the upper outrigger to pitch and rotate relative to the outrigger connector and to limit the pitch adjustment angle range of the upper outrigger.

[0011] The top end of the upper support arm is mounted on the lower column connector, and the bottom end of the rotating column is provided with the upper column connector. The upper column connector and the lower column connector are fitted together to form a fourth limiting joint. The fourth limiting joint is used to allow the upper column connector to rotate axially in the left and right directions relative to the lower column connector, and to limit the rotation angle range of the upper column connector; that is, the rotating column can rotate axially in the left and right directions relative to the upper support arm and the rotation angle is limited.

[0012] The top side of the rotating column is fitted with the bottom end of the rotating connector to form a fifth limiting joint. The fifth limiting joint is used to allow the rotating connector to rotate axially relative to the rotating column and to limit the rotation angle range of the rotating connector.

[0013] The top side of the rotary connector is fitted with the equipment mounting base to form a sixth limiting joint. The sixth limiting joint is used to allow the equipment mounting base to pitch up and down relative to the rotary connector and to limit the pitch adjustment angle range of the equipment mounting base.

[0014] The device mounting base is provided with a storage handle at its bottom, and the base or the side of the lower support arm is provided with a storage component. When the support arm is in the storage locked state, the storage handle is fixed in the storage component.

[0015] Preferably, the first limiting joint includes a first sliding groove, a first pin, and a first limiting member; the first sliding groove is a circumferential groove provided at the top of the base, the first pin is tightly fitted inside the first sliding groove of the base, and the first limiting member is installed at the bottom end of the lower support arm and extends into the first sliding groove; when the lower support arm rotates axially relative to the base, the first limiting member moves circumferentially along the first sliding groove; when the first pin collides with the first limiting member, the rotational adjustment of the lower support arm relative to the base is limited and stopped.

[0016] Preferably, the second limiting joint includes a lower support arm insert and a second slider. The lower support arm insert is installed at the top end of the lower support arm, and the second slider is a protruding part located at the tail end of the support arm connector. The lower support arm insert includes a circumferential slide table and a second limiting member located on the circumferential slide table. The second slider is fitted onto the circumferential slide table. When the support arm connector rotates axially relative to the lower support arm, the second slider moves circumferentially along the circumferential slide table. When the second slider collides with the second limiting member, the rotational adjustment of the support arm connector relative to the lower support arm is limited and stopped.

[0017] Preferably, the third limiting joint includes a third slider symmetrically installed on both sides of the support arm connector, and a third arc-shaped limiting groove symmetrically opened on the inner side of the bottom end of the upper support arm. The third slider is fitted in the third arc-shaped limiting groove. When the upper support arm is tilted up and down relative to the support arm connector, the third slider moves along the third arc-shaped limiting groove. When the third slider collides with both ends of the third arc-shaped limiting groove, the tilting adjustment of the upper support arm relative to the support arm connector is limited and stopped.

[0018] Preferably, the fourth limiting joint includes a fourth arc-shaped limiting groove formed at the top of the lower column connector and a fourth pin installed at the bottom of the upper column connector. The fourth pin is fitted into the fourth arc-shaped limiting groove. When the rotating column rotates axially relative to the upper support arm, the fourth pin moves along the fourth arc-shaped limiting groove. When the fourth pin collides and connects with both ends of the fourth arc-shaped limiting groove, the axial rotation adjustment of the rotating column relative to the upper support arm is limited and stopped.

[0019] Preferably, the fifth limiting joint includes a fifth irregular hole and a fifth pin. The fifth irregular hole is formed on the top side of the rotating column. The fifth irregular hole includes an inner hole and a fifth arc-shaped limiting groove. The fifth arc-shaped limiting groove is formed by radially excavating a certain arc segment around the inner hole. The tail end of the rotating connector is inserted into the fifth irregular hole. The fifth pin is installed on the side of the tail end of the rotating connector and inserted into the fifth arc-shaped limiting groove. When the rotating connector rotates axially relative to the rotating column, the fifth pin moves arc-shaped within the fifth arc-shaped limiting groove. When the fifth pin collides and connects with both ends of the fifth arc-shaped limiting groove, the axial rotation adjustment of the rotating connector relative to the rotating column is limited and stopped.

[0020] Preferably, the sixth limiting joint includes a sixth arc-shaped limiting groove formed on both sides of the rotary connector, and a sixth pin correspondingly installed on both sides of the tail end of the equipment mounting base. The sixth pin is fitted into the sixth arc-shaped limiting groove. When the equipment mounting base is tilted up and down relative to the rotary connector, the sixth pin moves within the sixth arc-shaped limiting groove. When the sixth pin collides and connects with both ends of the sixth arc-shaped limiting groove, the tilt adjustment of the equipment mounting base relative to the rotary connector is limited and stopped.

[0021] Preferably, the front of the device mounting base is used for fixing and installing medical devices, the back of the device mounting base is detachably mounted on the rotary connector, and the storage handle is connected to the bottom of the device mounting base.

[0022] Preferably, the storage component includes a socket and a locking component. The socket matches the storage handle. When the support arm is stored, the storage handle is inserted into the socket and the locking component is used to fix and lock the storage handle in the socket.

[0023] Preferably, when the support arm is fully retracted, the retractable handle is inserted parallel to the socket.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. The outrigger of this invention is equipped with six adjustable joints, making the outrigger adjustment more flexible and the adjustment range wider. Each joint performs a single adjustment function, such as rotation or pitch, thereby improving the accuracy of joint adjustment and reducing the difficulty of adjustment. At the same time, each joint is equipped with a corresponding limiting mechanism, so that each joint can rotate or pitch within a specified angle range, further enhancing the support performance of the multi-joint outrigger, making the outrigger more versatile, and able to flexibly configure the angle range according to different surgical needs. The device position can be adjusted in multiple positions, which can adapt to the surgery of patients with different body shapes. In practical use, it is more time-saving and efficient, and has both load-bearing stability and adjustment range and accuracy requirements.

[0026] 2. All six sections of the outrigger of this invention are equipped with a limiting mechanism, which can effectively prevent collisions with surgical instruments when adjusting the position and posture of each joint, protect the surgical instruments from damage, and protect the patient from accidental injury.

[0027] 3. Each joint inside the outrigger is equipped with a rotation limit mechanism to restrict the outrigger and prevent it from rotating 360° around the base, thus protecting the internal surgical equipment cables from damage.

[0028] 4. The support arm of the present invention is equipped with a handle fixing component. A storage handle is added under the equipment fixing base, and a storage component is set on the lower support arm. When the support arm is fully retracted, the storage handle is inserted parallel to the storage component, which is convenient and quick to operate and locks the storage handle quickly. This locks the entire support arm in a fully retracted state, effectively reducing the storage space occupied by the support arm. At the same time, it prevents the support arm from loosening, extending, or being damaged by collision during transportation or movement. This helps to ensure that the support arm can still maintain its superior support and flexible adjustability after transportation and storage. Attached Figure Description

[0048] To provide a further understanding of the purpose, structure, features, and functions of the present invention, this section will describe in detail specific embodiments of the present invention.

[0049] In the description of this invention, it should be noted that the terms "head", "tail", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0050] If the terms "first" or "second" are used to distinguish technical features, they should not be interpreted as indicating or implying relative importance, or implicitly indicating the number of technical features or the order of the technical features.

[0051] In the description of this invention, unless otherwise explicitly defined, terms such as "set", "install", and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0052] The following is for reference. Figures 1 to 11 The six-joint, multi-angle, retractable, and locking support arm of the present invention will be described in detail.

[0053] The adjustment of a medical outrigger is achieved through the joints of each outrigger. The connection structure between the outrigger and the joints, the number of joints, and the adjustment method all directly affect the support and adjustment effect of the medical outrigger. Currently, different surgical scenarios require different medical devices for support, and the requirements for the outrigger's extension range, adjustment height, and support stability also vary. Existing outriggers often only have a few joints to meet specific requirements, lacking sufficient flexibility and adaptability to cope with different surgical scenarios. Therefore, the purpose of this invention is to design a medical outrigger with a large number of joints, a large extension range, strong adjustment flexibility, and good support stability. The adjustment of a medical outrigger typically includes left-right rotation angle adjustment and up-down pitch angle adjustment.

[0054] Please refer to the reference. Figure 1 A six-joint, multi-angle, retractable, and lockable support arm includes a base 1, a lower support arm 2, a support arm connector 3, an upper support arm 4, a lower column connector 5, an upper column connector 6, a rotating column 7, a rotating connector 8, an equipment fixing seat 9, a storage handle 10, and a storage component 11.

[0055] The bottom end of the base 1 is the mounting end 110. The top end of the base 1 mates with the bottom end of the lower support arm 2 to form a first limiting joint 100. The first limiting joint 100 is used to allow the lower support arm 2 to rotate axially left and right relative to the base 1 and to limit the range of rotation angle of the lower support arm 2. The mounting end 110 of the base 1 is used to install and fix the support arm in a designated position, such as wall mounting, ceiling mounting, floor mounting, or installation on other equipment, depending on the specific environment and requirements of the operating room and other medical facilities. The mounting end 110 can be fixed using common medical support arm installation methods such as screw tightening, pin fixing, and clamping locking.

[0056] With the base 1 fixed, the first limiting joint 100 restricts the lower support arm 2 to rotate left and right to adjust its angle and posture, limiting the range of its left and right rotation angle. The presence of the first limiting joint 100 prevents the lower support arm 2 from rotating 360° around the base 1. Starting from one end of the joint's limiting point, the lower support arm 2 rotates in a circle until it reaches the other end. After one complete rotation adjustment process, the rotation angle is less than 360°. The specific adjustable range of the first limiting joint 100 can be set according to actual conditions and needs. Setting the first limiting joint 100 to prevent the lower support arm 2 from rotating 360° relative to the base 1 serves two purposes: first, it coordinates with the rotation adjustment of other joints to improve the support stability of the arm; second, it effectively prevents the cables inside the joint from being twisted or wound more than 360°, thus protecting the cables from damage.

[0057] Please refer to the reference. Figure 2 In some embodiments, the first limiting joint 100 includes a first sliding groove 101, a first pin 102, and a first limiting member 103. The first sliding groove 101 is a circumferential groove provided at the top of the base 1. The first pin 102 is tightly fitted inside the first sliding groove 101 of the base 1. The first limiting member 103 is installed at the bottom end of the lower support arm 2 and extends into the first sliding groove 101. When the lower support arm 2 rotates axially relative to the base 1, the first limiting member 103 moves circumferentially along the first sliding groove 101. When the first pin 102 collides with the first limiting member 103, the rotation adjustment of the lower support arm 2 relative to the base 1 is limited and stopped.

[0058] This structure is simple and easy to install, enabling simultaneous joint rotation and limiting functions at a relatively low cost. Furthermore, the first limiting joint 100, as the bottom joint, requires the lowest adjustment precision compared to the other five rotating joints; therefore, its rotation angle can be designed with a wider adjustment range compared to the other five rotating joints. (See attached diagram) Figure 2As shown, the first groove 101 of the first limiting joint 100 can be a full-circumferential groove, with a pin only set within the first groove 101 as a limiting point to prevent the first limiting member 103 from rotating repeatedly 360° or even multiple times within the first groove 101. The first limiting member 103 can be any component with a certain volume and width, ensuring that the first pin 102 cannot pass through the gap between the first limiting member 103 and the first groove 101. Alternatively, other components, such as a locking switch, can be placed at the first limiting member 103, making efficient use of space and achieving an aesthetically pleasing appearance.

[0059] In one embodiment, a rotating plunger can be installed in the first limiting member 103, and a fixing hole is provided in the first sliding groove 101. When the switch of the rotating plunger is pulled outward, the retractable pin at the bottom of the rotating plunger extends downward into the fixing hole and locks, thereby achieving the effect of locking the first limiting joint. In addition to this locking method, the first limiting joint can also be equipped with any joint locking component commonly used in outriggers in the prior art.

[0060] In one embodiment, the first limiting member 103 is a cylinder or a fan-shaped cylinder with a bottom surface that matches the first sliding groove 101. The first limiting member 103 is inserted into the first sliding groove 101, occupying part of the track of the first pin 102, so that the first pin 102 cannot rotate in circles within the first sliding groove 101. The shape and bottom arc length of the first limiting member 103 can be changed according to the actual required angle adjustment range. Therefore, the angle adjustment range of the first limiting joint 100 of the present invention can be limited according to actual needs. For example, if the central angle corresponding to the bottom arc length of the first limiting member 103 is 30°, then the first pin 102 can rotate within the central angle range of 330° in the first sliding groove 101. That is, the rotation angle adjustment range of the lower support arm 2 relative to the base 1 is [0, 330°]. If the bottom arc length of the first limiting member 103 is changed, the adjustable range of the rotation angle of the lower support arm 2 relative to the base 1 will also change. If the bottom arc length of the first limiting member 103 increases, the adjustable angle range of the first limiting joint 100 will decrease; if the bottom arc length of the first limiting member 103 decreases, the adjustable angle range of the first limiting joint 100 will increase.

[0061] The top end of the lower support arm 2 is fitted with the support arm connector 3 to form a second limiting joint 200. The second limiting joint 200 is used to allow the support arm connector 3 to rotate axially to the left and right relative to the lower support arm 2 and to limit the rotation angle range of the support arm connector 3.

[0062] Using the lower support arm 2 as a reference, under the action of the second limiting joint 200, the support arm connector 3 can only rotate left and right to adjust its angle, and cannot rotate 360° around the lower support arm 2. That is, the support arm connector 3 starts from one end of the joint limit and rotates in a circle until it reaches the other end of the joint limit. After one complete rotation adjustment process, the rotation angle is less than 360°. Its functions are twofold: first, to coordinate with the rotation adjustment of other joints and improve the support stability of the support arm; second, to effectively prevent the cables inside the joint from being wound and twisted more than 360°, which helps protect the cables inside the support arm from damage. The specific adjustable range of the angle of the second limiting joint 200 can be set according to the actual situation and needs.

[0063] Please refer to the reference. Figure 3 In some embodiments, the second limiting joint 200 includes a lower support arm insert 201 and a second slider 202. The lower support arm insert 201 is installed at the top end of the lower support arm 2, and the second slider 202 is a protruding part located at the tail end of the support arm connector 3. The lower support arm insert 201 includes a circumferential slide 2011 and a second limiting member 2012 located on the circumferential slide 2011. The second slider 202 is fitted onto the circumferential slide 2011. When the support arm connector 3 rotates axially relative to the lower support arm 2, the second slider 202 moves circumferentially along the circumferential slide 2011. When the second slider 202 collides with the second limiting member 2012, the rotational adjustment of the support arm connector 3 relative to the lower support arm 2 is limited and stopped.

[0064] The aforementioned second limiting joint 200 has a simple structure. A lower support arm insert 201 is installed at the top of the lower support arm 2, and it is rotatably connected to the support arm connector 3, simultaneously achieving the functions of joint connection, rotation, and limiting. Preferably, the lower support arm insert 201 can be made into an integral part, which can be manufactured by mold molding or other processes. In this way, the second limiting member 2012 and the circumferential slide table 2011 are integrated, providing a good limiting effect. This prevents excessive force from medical personnel adjusting the angle, which could cause the limiting structure to loosen or be damaged, affecting the limiting effect and thus impacting the support stability and adjustment accuracy of the arm. The circumferential slide table 2011 provides a complete circumferential sliding track. Based on this, a section is extended upwards in an arc to form the protruding second limiting member 2012. By changing the arc length of the second limiting member 2012, the rotation angle range of the rotating connector can be quickly changed. Therefore, the angle adjustment range of the second limiting joint 200 of this invention can be limited according to actual needs, making it simple to manufacture, low in cost, and easy to install. For example, if the central angle of the second limiting member 2102 on the lower support arm insert 201 is 60°, then the left and right rotation angle range of the support arm connector 3 relative to the lower support arm 2 is [0, 300°]. If the arc length of the second limiting member 2102 on the lower support arm insert 201 is increased, the corresponding central angle is increased, and the left and right rotation adjustable angle range of the second limiting joint is decreased. If the arc length of the second limiting member 2102 on the lower support arm insert 201 is decreased, the corresponding central angle is decreased, and the left and right rotation adjustable angle range of the second limiting joint is increased.

[0065] The side of the outrigger connector 3 is connected to the bottom of the upper outrigger 4 to form a third limiting joint 300. The third limiting joint is used to allow the upper outrigger 4 to pitch up and down relative to the outrigger connector 3 and to limit the pitch adjustment angle range of the upper outrigger 4.

[0066] Based on the outrigger connector 3, under the action of the third limiting joint 300, the upper outrigger 4 can only adjust its pitch angle and posture, and the pitch angle adjustment range is limited; the outrigger connector 3 starts from one end of the joint limit and rotates around the circumference until it rotates to the other end of the joint limit. The specific angle adjustment range can be set according to the actual situation and needs.

[0067] Please refer to the reference. Figure 4 and Figure 5In some embodiments, the third limiting joint 300 includes a third slider 301 symmetrically installed on both sides of the support arm connector 3, and a third arc-shaped limiting groove 302 symmetrically opened on the inner side of the bottom end of the upper support arm 4. The third slider 301 is fitted into the third arc-shaped limiting groove 302. The third slider 301 can be any component with a certain volume and width, preferably matching the third arc-shaped limiting groove 302. Preferably, the third slider 301 and the support arm connector 3 are integrally formed, for example, by integral molding or other integral manufacturing methods. When the upper support arm 4 is tilted up and down relative to the support arm connector 3, the third slider 301 moves along the third arc-shaped limiting groove 302. When the third slider 301 collides with the two ends of the third arc-shaped limiting groove 302, the tilting adjustment of the upper support arm 4 relative to the support arm connector 3 is limited and stopped. The third limiting joint 300 of this structure is simple in structure, easy to install, has low resistance during adjustment, and is flexible in use. Similarly, during manufacturing, the adjustable angle range of the third limiting joint 300 can be easily changed by altering the arc length and central angle of the third arc-shaped limiting groove 302. Furthermore, the structure of this slider sliding within the limiting groove provides strong support, effectively preventing loosening or damage during adjustment. For example, if the arc angle corresponding to the third limiting arc-shaped groove 302 is 150°, then the vertical pitch angle adjustment range of the third limiting joint 300 is [0, 150°]. If the arc length of the third limiting arc-shaped groove 302 is increased, its corresponding central angle increases, thus increasing the vertical pitch angle adjustment range of the third limiting joint 300. Conversely, if the arc length of the third limiting arc-shaped groove 302 is decreased, its corresponding central angle decreases, thus decreasing the vertical pitch angle adjustment range of the third limiting joint 300.

[0068] The top end of the upper support arm 4 is installed on the lower column connector 5, and the bottom end of the rotating column 7 is provided with an upper column connector 6. The upper column connector 6 and the lower column connector 5 are installed together to form a fourth limiting joint 400. The fourth limiting joint 400 is used to allow the upper column connector 6 to rotate axially left and right relative to the lower column connector 5, and to limit the rotation angle range of the upper column connector 6, that is, the rotating column 7 can rotate axially left and right relative to the upper support arm 4 and the rotation angle is limited.

[0069] Using the upper support arm 4 as a reference, under the action of the fourth limiting joint 400, the lower column connector 5 can only rotate left and right to adjust its angle, and the rotation angle is less than 360°. That is, the lower column connector 5 starts from one end of the joint limit and rotates around the circumference until it reaches the other end of the joint limit. After one complete rotation adjustment process, the rotation angle is less than 360°. Its functions are twofold: first, to coordinate with the rotation adjustment of other joints and improve the support stability of the support arm; second, to effectively prevent the cables inside the joint from being twisted and wound more than 360°, which helps protect the cables inside the support arm from damage. The specific adjustable range of the fourth limiting joint 400 can be set according to the actual situation and needs.

[0070] Please refer to the reference. Figure 6 and Figure 7 In some embodiments, the fourth limiting joint 400 includes a fourth arc-shaped limiting groove 401 opened at the top of the lower column connector 5, and a fourth pin 402 installed at the bottom of the upper column connector 6. The fourth pin 402 can also be any component with a certain volume and width. The fourth pin 402 is fitted into the fourth arc-shaped limiting groove 401. When the rotating column 7 rotates axially relative to the upper support arm 4, the fourth pin 402 moves along the fourth arc-shaped limiting groove 401. When the fourth pin 402 collides and connects with both ends of the fourth arc-shaped limiting groove 401, the axial rotation adjustment of the rotating column 7 relative to the upper support arm 4 is limited and stopped.

[0071] The fourth limiting joint 400 of this structure is simple in structure, easy to install, and flexible in adjustment. The angle adjustment range of the fourth limiting joint 400 can be changed by changing the arc length of the fourth arc-shaped limiting slide 401. For example, if the arc angle corresponding to the fourth arc-shaped limiting slide 401 is 300°, then the vertical pitch angle adjustment range of the fourth limiting joint 400 is [0, 300°]. If the arc length of the fourth arc-shaped limiting slide 401 is increased, the corresponding central angle is increased, and the horizontal rotation angle adjustment range of the fourth limiting joint 400 is increased. If the arc length of the fourth arc-shaped limiting slide 401 is decreased, the corresponding central angle is decreased, and the vertical pitch angle adjustment range of the fourth limiting joint 400 is decreased.

[0072] Preferably, the fourth limiting joint 400 is closer to the top of the arm. Due to the requirements of adjustment accuracy and support stability, the arc center angle of the fourth arc-shaped limiting groove 401, that is, the range of angles that the joint can rotate and adjust, needs to be smaller than that of the first limiting joint 100.

[0073] The top side of the rotating column 7 is fitted with the bottom end of the rotating connector 8 to form a fifth limiting joint 500. The fifth limiting joint 500 is used to allow the rotating connector 8 to rotate axially relative to the rotating column 7 and to limit the rotation angle range of the rotating connector 8. With the rotating column 7 as a reference, under the action of the fifth limiting joint 500, the rotating connector 8 is installed on the top side of the rotating column 7 and can only be adjusted left and right on the vertical plane. The adjustment angle is limited, and a more specific angle adjustment range can be set according to the actual situation and needs.

[0074] Please refer to the reference. Figure 8 and Figure 9 In some embodiments, the fifth limiting joint 500 includes a fifth irregular hole 501 and a fifth pin 502. The fifth irregular hole 501 is formed on the top side of the rotating column 7. The fifth irregular hole 501 includes an inner hole 5011 and a fifth arc-shaped limiting groove 5012. The fifth arc-shaped limiting groove 5012 is formed by radially excavating a certain arc segment around the inner hole 5011. The tail end of the rotating connector 8 is inserted into the fifth irregular hole 501. The fifth pin 502 is installed on the side of the tail end of the rotating connector 8 and inserted into the fifth arc-shaped limiting groove 5012. When the rotating connector 8 rotates axially relative to the rotating column 7, the fifth pin 502 moves arc-shaped within the fifth arc-shaped limiting groove 5012. When the fifth pin 502 collides and connects with both ends of the fifth arc-shaped limiting groove 5012, the axial rotation adjustment of the rotating connector 8 relative to the rotating column 7 is limited and stopped. The fifth limiting joint 500 of this structure is essentially a sliding limiting combination of a slider and a limiting groove, which is easy to assemble, allows for rotational adjustment, and provides good limiting effect. The fifth pin 502 can be replaced with any component with a certain volume and width.

[0075] The specific angle adjustment range of the fifth limiting joint 500 can be set according to actual conditions and needs, and can be adjusted by changing the arc length and central angle of the fifth arc-shaped slide 5012. For example, if the arc angle corresponding to the fifth arc-shaped limiting slide 5012 is 320°, then the vertical pitch angle adjustment range of the fifth limiting joint 5012 is [0, 320°]. If the arc length of the fifth arc-shaped limiting slide 5012 is increased, its corresponding central angle is increased, and the horizontal rotation angle adjustment range of the fifth limiting joint 500 is increased. If the arc length of the fifth arc-shaped limiting slide 5012 is decreased, its corresponding central angle is decreased, and the vertical pitch angle adjustment range of the fifth limiting joint 500 is decreased.

[0076] The top side of the rotary connector 8 is fitted with the equipment mounting base 9 to form a sixth limiting joint 600. The sixth limiting joint 600 is used to allow the equipment mounting base 9 to tilt up and down relative to the rotary connector 8, and to limit the pitch adjustment angle range of the equipment mounting base 9. With the rotary connector 8 as the reference, under the action of the sixth limiting joint 600, the equipment mounting base 9 can only adjust its pitch angle and posture up and down, and the pitch adjustment angle range is limited. A more specific angle adjustment range can be set according to the actual situation and needs.

[0077] Please refer to the reference. Figure 10 In some embodiments, the sixth limiting joint 600 includes a sixth arc-shaped limiting groove 601 formed on both sides of the rotary connector 8, and a sixth pin 602 correspondingly installed on both sides of the tail end of the equipment mounting base 9. The sixth pin 602 is fitted into the sixth arc-shaped limiting groove 601. When the equipment mounting base 9 is tilted up and down relative to the rotary connector 8, the sixth pin 602 moves within the sixth arc-shaped limiting groove 601. When the sixth pin 602 collides and connects with both ends of the sixth arc-shaped limiting groove 601, the tilt adjustment of the equipment mounting base 9 relative to the rotary connector 8 is limited and stopped.

[0078] For example, if the arc angle corresponding to the sixth limiting arc groove 601 is 330°, then the pitch angle adjustment range of the sixth limiting joint 600 is [0, 330°]. If the arc length of the sixth limiting arc groove 601 is increased, its corresponding central angle is increased, and the left and right rotation angle adjustment range of the sixth limiting joint 600 is increased. If the arc length of the sixth limiting arc groove 601 is decreased, its corresponding central angle is decreased, and the pitch angle adjustment range of the sixth limiting joint 600 is decreased.

[0079] In some preferred embodiments, two sets of sixth limiting joints 600 are symmetrically provided on both sides of the top of the rotary connector 8 and the two sides of the equipment mounting base 9. When the pitch angle of the equipment mounting base 9 is adjusted, the sixth limiting joints 600 on both sides move synchronously, making the adjustment of both sides of the equipment mounting base 9 more balanced.

[0080] Please refer to the reference. Figure 1 In some embodiments, the front of the device holder 9 is used to fix and install medical devices, the back of the device holder 9 is detachably mounted on the rotary connector 8, and the storage handle 10 is connected to the bottom of the device holder 9. The device holder 9 is a detachable structure, which facilitates the replacement of different device holders 9 to fix different medical devices, so as to meet the needs of different surgical scenarios.

[0081] Please refer to the reference. Figure 11The bottom of the equipment mounting base 9 is provided with a storage handle 10, and the side of the lower support arm 2 is provided with a storage component 11. The storage component 11 includes a socket and a locking component. The socket matches the storage handle 10. When the support arm is stored, the storage handle 10 is inserted into the socket and the locking component is used to fix and lock the storage handle 10 in the socket.

[0082] In some preferred embodiments, when the support arm is fully retracted, the storage handle 10 is inserted parallel to the socket, which facilitates quick storage and locking and prevents the storage handle 10 from interfering with other parts of the support arm.

[0083] The six-joint, multi-angle, retractable, and locking outrigger protected by this invention has six adjustable joints, each capable of adjusting only one direction, such as left-right rotation or up-down tilt, improving the accuracy and flexibility of joint adjustment and reducing adjustment difficulty. Each joint is equipped with a limiting structure to restrict the adjustment angle, limiting the outrigger's 1360° rotation around the base, protecting internal surgical equipment wiring from damage, and effectively preventing collisions with surgical instruments during joint position and posture adjustments, thus protecting the instruments from damage and the patient from accidental injury. This also further enhances the support performance of the multi-joint outrigger.

[0084] This invention enhances the versatility of the outrigger, allowing for flexible configuration of angles to suit different surgical needs. The device position can be adjusted to multiple locations, providing multi-position, wide-range adaptability, and rapid adjustment capabilities. This helps operators maneuver the outrigger more effectively, better serving patients during surgery. It can adapt to surgeries performed on patients of different body types, resulting in greater time and efficiency in practical use. It also maintains load-bearing stability and meets requirements for adjustment range and precision. The addition of a handle fixing component enhances the outrigger's storage capacity, facilitating the movement and transportation of the surgical equipment.

[0085] All six joints of this invention can be selected from the joint locking components of existing medical outriggers, such as damped joints. After medical personnel adjust the outrigger to a suitable angle, the adjusted joint automatically locks and stops under the action of damping. Other joint locking and fixing methods include, but are not limited to, pin insertion and removal locking, button lock locking, etc.

[0086] The six-joint, multi-angle retractable and locking outrigger of the present invention, apart from the six joints and the storage and fixing components described in the above embodiments, can directly adopt the structures and components commonly used in medical outriggers in the prior art for other structural components, such as the connecting rods, wiring, transmission mechanism, and locking device inside the outrigger.

[0087] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0088] The present invention has been described in the above-described embodiments. However, the above embodiments are merely examples for implementing the present invention and are used to help understand the technical solutions and core ideas of this application. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention; on the contrary, the technical solutions described in the foregoing embodiments can still be modified, or some of the technical features can be equivalently replaced; any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
