[0053] See also Figures 1 to 11 , an embodiment of the present application provides a medical accessory connecting device 1.

[0054] The medical accessory connecting device 1 is used to connect a medical accessory and a medical device body.

[0055] It can be understood that medical accessories refer to medical devices such as operating table accessories. For example, medical accessories can be support parts.

[0056] It is understood that medical equipment refers to instruments, equipment, appliances, etc. used alone or in combination on the human or animal body. Medical equipment can be diagnostic equipment, surgical equipment, or other auxiliary equipment, without limitation. For example, the medical equipment can be an operating table.

[0057] An embodiment of the present application provides an operating table, comprising an operating table main body, a support member, and a medical accessory connection device 1 of any embodiment of the present application.

[0058] The support member is used to support a part of the medical object.

[0059] It should be noted that the parts of the medical object may be the head, hands and other parts, and the support member can support the head, hands and other parts to facilitate medical staff to perform surgical operations.

[0060] The medical accessory connection device 1 connects the main operating table and the support member. For example, the support member is used to support the patient's head. During surgery, the patient's head is supported and fixed by the support member, while the lower body of the patient is supported by the main operating table, facilitating procedures such as ophthalmic and neurosurgery.

[0061] See also Figure 1 、 Figure 6 and Figure 9 The medical accessory connecting device 1 includes a bracket 10 and at least one interface module 11 .

[0062] At least one interface module 11 includes an interface body 111 and a first adjustment member 112 .

[0063] See also Figure 4 、 Figure 8 and Figure 11 The interface body 111 includes an interface seat 1111 and a first tightening member 1112 at least partially disposed in the interface seat 1111. The interface seat 1111 has a mounting groove 1111a and a clamping space 1111b. The bracket 10 is passed through the mounting groove 1111a. The clamping space 1111b is used to accommodate the connecting part of the medical device body.

[0064] The bracket 10 can provide support for the medical accessories connected to the interface module 11, and the mounting groove 1111a is used to provide space for the connection between the bracket 10 and the interface body 111. The clamping space 1111b is used to provide space for the connection between the connecting part and the interface module 11.

[0065] It can be understood that the connecting part refers to the general term for the structure of the medical device body used to cooperate with the clamping space 1111b. For example, the connecting part can be a side rail, a slide rail, etc.

[0066] For example, the operating table body has side rails on both sides along the width direction, each of which is connected to at least one interface module 11. The side rails are arranged in the clamping space 1111b. The medical accessory connection device 1 may also include an accessory locking module 12, and the support member is connected to the accessory locking module 12. In other words, the medical accessory connection device 1 connects accessories such as the support member to the operating table body through the interface module 11 and the accessory locking module 12.

[0067] The first adjusting member 112 has a locking position and a releasing position.

[0068] In the locking position, the first adjusting member 112 applies a force in a first direction to the first pressing member 1112 , and the first pressing member 1112 locks the assembled connection portion in the clamping space 1111b , and locks the interface body 111 on the bracket 10 .

[0069] In the release position, the interface body 111 can move along the length direction of the bracket 10 for adjustment, and the interface body 111 can move relative to the connecting portion.

[0070] The first direction is perpendicular to the length direction of the bracket 10 .

[0071] Specifically, in the locking position, the first adjusting member 112 applies a force to the first tightening member 1112, and the first tightening member 1112 moves along the first direction to lock the connecting part in the clamping space 1111b, and the connecting part cannot move freely to achieve connection with the main body of the medical device, and the first tightening member 1112 locks the interface main body 111 on the bracket 10, so that the interface module 11 is locked and matched with the bracket 10, that is, the first adjusting member 112 drives the first tightening member 1112 to achieve simultaneous locking of the bracket 10 and the connecting part.

[0072] In the release position, the first tightening member 1112 releases the locking fit with the connecting part, and releases the locking fit between the interface body 111 and the bracket 10. The interface body 111 can move along the length direction of the bracket 10 and move relative to the connecting part to adjust the distance between each interface module 11, or adjust the distance between the interface module 11 and the accessory locking module 12. In this way, the medical accessory connecting device 1 can adapt to connecting parts and medical accessories of different specifications.

[0073] It should be noted that the first direction is unidirectional. For example, the first direction may be an upward direction, that is, the first pressing member 1112 moves upward under the driving action of the first adjusting member 112 to lock the connecting portion.

[0074] It should be noted that the bracket 10 is inserted into the mounting groove 1111a. In the locked position, the first pressing member 1112, under the action of the first adjusting member 112, locks the interface body 111 to the bracket 10. This means that the interface body 111 and the bracket 10 are locked in the docking position, and relative movement between the interface body 111 and the bracket 10 is prevented. In the released position, the interface body 111 can move relative to the bracket 10 through the mounting groove 1111a to change the docking position of the interface body 111 on the bracket 10.

[0075] The medical accessory connecting device 1 provided in the embodiment of the present application, in the locked position, drives the first adjusting member 112 to cause the first tightening member 1112 to simultaneously lock the connecting portion of the medical device body and the bracket 10, thereby achieving one-step locking, so that the connection between the medical accessory connecting device 1 and the connecting portion and the medical accessory is more stable and reliable. In the released position, the movement of the interface body 111 relative to the bracket 10 and the connecting portion can facilitate the adjustment of the distance between the interface modules 11 and the distance between the interface module 11 and the accessory locking module 12, thereby adapting to connecting portions and medical accessories of different specifications, increasing the adjustability and adaptability of the medical accessory connecting device 1, and the medical accessory connecting device 1 is simple to operate and highly convenient to use.

[0076] For some examples, see Figure 4 、 Figure 8 and Figure 11 The bracket 10 is provided with a slide groove 10a, which extends along the length direction of the bracket 10. A portion of the interface module 11 is passed through the slide groove 10a to limit the sliding stroke of the interface body 111 along the length direction of the bracket 10.

[0077] In this embodiment, the setting of the slide groove 10a can provide sliding space for the interface body 111, increase the flexibility of the medical accessory connecting device 1, and at the same time, the slide groove 10a can also limit the movement range of the interface body 111, reduce the probability of unstable connection or scratching with other components due to excessive sliding, and at the same time, the setting of the slide groove 10a can also facilitate the docking of the interface module 11 and the bracket 10 to provide a positioning reference.

[0078] It should be noted that a part of the interface module 11 is passed through the slide groove 10a, which may be a part of the first adjusting member 112, a part of the first tightening member 1112 passed through the slide groove 10a, or other structures of the interface module 11 passed through the slide groove 10a, and there is no limitation here.

[0079] For some examples, see Figure 4 and Figure 8The interface module 11 also includes an elastic member 113, which applies an elastic force to the first tightening member 1112 toward the bracket 10. In the release position, a portion of the first tightening member 1112 is pressed against the bracket 10 under the action of the elastic force to generate a damping force on the sliding of the interface body 111 relative to the bracket 10.

[0080] It should be noted that the damping force does not affect the sliding of the interface body 111 relative to the bracket 10. The damping force can control the sliding speed and accuracy of the interface body 111 relative to the bracket 10, thereby increasing stability.

[0081] Specifically, in the locked position, the first adjusting member 112 drives the first tightening member 1112 to move in the first direction. At this time, the elastic member 113 is elastically deformed by the force and stores elastic potential energy. In the released position, the elastic member 113 releases the elastic potential energy, and at least a portion of the first tightening member 1112 moves toward the direction close to the bracket 10 under the elastic force of the elastic member 113 and abuts against the bracket 10. When the interface body 111 slides relative to the bracket 10, the elastic member 113 can make part of the first tightening member 1112 always abut against the bracket 10. The damping force can help control the speed and accuracy of the interface body 111 sliding along the bracket 10, reduce the rapid sliding of the interface body 111 due to gravity or inertia, increase the stability of the sliding of the interface body 111 relative to the bracket 10, and improve the operation accuracy.

[0082] The specific structure and location of the elastic member 113 are not limited.

[0083] Exemplarily, the elastic member 113 may be a spring or other element with elastic properties, which is not limited here.

[0084] For some examples, see Figure 4 and Figure 8 The first tightening member 1112 includes a first rod segment 11121 and a boss 11122. The boss 11122 is connected to one end of the first rod segment 11121 close to the bracket 10. The first rod segment 11121 and the boss 11122 are both arranged in the interface seat 1111. The elastic member 113 is sleeved on the outer periphery of the first rod segment 11121. One end of the elastic member 113 abuts against the interface seat 111, and the other end abuts against the boss 11122.

[0085] It can be understood that the end of the boss 11122 away from the bracket 10 contacts the elastic member 113 to limit the elastic member 113, and the end of the boss 11122 close to the bracket 10 can be used to contact the bracket 10.

[0086] That is to say, the first rod segment 11121 is arranged close to the connecting part, and the boss 11122 is arranged close to the bracket 10. When in the locked position, the end of the first rod segment 11121 away from the bracket 10 presses against the connecting part to achieve locking of the connecting part, and the elastic member 113 is elastically deformed under the movement of the boss 11122. At this time, the end of the boss 11122 close to the bracket 10 is spaced apart from the bracket 10; when in the released position, the elastic member 113 releases elastic potential energy, and the boss 11122 moves toward the bracket 10 under the action of the elastic force until it abuts against the bracket 10. During the sliding process of the interface body 111 relative to the bracket 10, the boss 11122 can always maintain contact with the bracket 10, thereby increasing the sliding stability.

[0087] In this embodiment, the setting of the first rod segment 11121 and the boss 11122 can make the movement of the first tightening member 1112 smoother, and can limit the elastic member 113 to increase the movement stability. In the locked position, the locking stability is high. In the released position, the damping force between the boss 11122 and the bracket 10 can also control the sliding of the interface body 111 within a stable range. The structure of the first tightening member 1112 is simple and reliable.

[0088] For some examples, see Figure 4 、 Figure 5 and Figure 11 The interface body 111 also includes a second tightening member 1113. While the first adjusting member 112 applies force to the first tightening member 1112, it applies force to the second tightening member 1113 along the second direction so that the second tightening member 1113 is pressed against the bracket 10, thereby achieving the locking of the interface body 111 and the bracket 10; wherein the second direction is opposite to the first direction.

[0089] It can be understood that there is no limit to the way in which the second tightening member 1113 is supported on the bracket 10. It can be that the first tightening member 1112 is not in contact with the second tightening member 1113, and the first adjusting member 112 applies a force in the first direction to the first tightening member 1112 and a force in the second direction to the second tightening member 1113, thereby respectively achieving the locking of the connecting part and the locking of the bracket 10; or it can be that the first tightening member 1112 is in contact with the second tightening member 1113, and the driving force of the first adjusting member 112 first acts on the first tightening member 1112 and then acts on the second tightening member 1113.

[0090] In this embodiment, the provision of the second tightening member 1113 achieves all-round locking of the interface body 111, the bracket 10, and the connecting portion, further increasing the matching stability and tightness of the interface body 111, the bracket 10, and the connecting portion.

[0091] It should be noted that the second direction is unidirectional. For example, the first direction is the upward direction, and the second direction is the downward direction. That is, in the locked position, the first tightening member 1112 moves upward to lock the connection part, and the second tightening member 1113 moves downward to abut against the bracket 10.

[0092] In some embodiments, the first adjusting member 112 is threadedly engaged with the second pressing member 1113 , and the rotation axis of the first adjusting member 112 is parallel to the first direction, so that the first adjusting member 112 generates a linear displacement along the first direction during rotation relative to the second pressing member 1113 .

[0093] That is, the first tightening member 1112 and the second tightening member 1113 can be driven to move by driving the first adjusting member 112 to rotate around the first direction.

[0094] The first adjusting member 112 and the second pressing member 1113 are threadedly matched, and can use the characteristics of the thread to convert the rotational motion into a linear motion.

[0095] In the locked position, the first adjusting member 112 rotates, generating a linear displacement along the first direction, so that the first tightening member 1112 is subjected to a force along the first direction, and the second tightening member 1113 is subjected to a force along the second direction, thereby achieving the locking of the connecting part and the bracket 10; in the released position, the first adjusting member 112 rotates in the opposite direction, generating a reverse linear displacement along the first direction. At this time, the pressure of the first tightening member 1112 and the second tightening member 1113 on the connecting part and the bracket 10 is reduced, and the interface body 111 can move along the length direction of the bracket 10.

[0096] In this embodiment, the threaded cooperation between the first adjusting member 112 and the second tightening member 1113 can facilitate the control of the displacement of the first adjusting member 112 to accurately adjust the locking stability. At the same time, the structure is simple, which facilitates the rapid switching between the locking position and the release position.

[0097] For some examples, see Figure 4 The bracket 10 includes a first side wall 101 and a second side wall 102 arranged at intervals along the first direction, and the second tightening member 1113 is linearly movably arranged between the first side wall 101 and the second side wall 102. The first end of the first adjusting member 112 passes through the first side wall 101 and the second tightening member 1113, and can contact the end of the first tightening member 1112 away from the clamping space 1111b. The first adjusting member 112 is used to drive the second tightening member 1113 to move toward the first side wall 101 during the continued rotation after driving the first tightening member 1112 to lock the connection part, thereby pressing the second tightening member 1113 against the inner surface of the first side wall 101.

[0098] It can be understood that the second tightening member 1113 is accommodated in the space between the first side wall 101 and the second side wall 102, and the second tightening member 1113 can move between the first side wall 101 and the second side wall 102, which means that in the locked position, the second tightening member 1113 can move along the second direction to abut against the first side wall 101, and in the released position, the second tightening member 1113 can move along the length direction of the bracket 10 with the interface body 111.

[0099] It is understandable that at least a portion of the outer contour of the second pressing member 1112 is in the shape of a square tube. In this way, the second pressing member 1112 can only move but cannot rotate.

[0100] Specifically, the locking process of the interface module 11 includes two stages.

[0101] Phase 1: The first adjusting member 112 starts to rotate, generating a driving effect on the first pressing member 1112 along the first direction, so that the first pressing member 1112 moves toward the connecting portion along the first direction, locking the connecting portion in the clamping space 1111b.

[0102] The second stage: after the first tightening member 1112 locks the connection part, the first adjusting member 112 continues to rotate. At this time, the first tightening member 1112 cannot continue to move. The force of the first adjusting member 112 acts on the second tightening member 1113, driving the second tightening member 1113 to move along the second direction toward the first side wall 101 until it abuts against the first side wall 101. The second tightening member 1113 locks the bracket 10, thereby realizing a stable connection between the interface body 111 and the bracket 10.

[0103] In this embodiment, the setting of the second tightening member 1113, and the cooperation between the first adjusting member 112, the first tightening member 1112 and the second tightening member 1113 can further lock the bracket 10 after the connection part is locked, thereby realizing the locking cooperation between the interface body 111 and the bracket 10, and the locking reliability is high.

[0104] For some examples, see Figure 10 The first adjusting member 112 is threadedly engaged with the interface seat 1111, and the rotation axis of the first adjusting member 112 intersects with the first direction. One end of the first adjusting member 112 extends between the first tightening member 1112 and the second tightening member 1113, and can simultaneously support the first tightening member 1112 and the second tightening member 1113. When the depth of the first adjusting member 112 inserted into the interface seat 1111 deepens, the first adjusting member 112 pushes the first tightening member 1112 and the second tightening member 1113 to move linearly in opposite directions.

[0105] Specifically, when the first adjusting member 112 rotates, it can generate a linear displacement along the thread direction, penetrating into or exiting the interface seat 1111 to achieve switching between the locked position and the released position. When the insertion depth of the first adjusting member 112 deepens during the rotation process, the forces applied to the first pressing member 1112 and the second pressing member 1113 are respectively in the first direction and the second direction. The first pressing member 1112 moves along the first direction to the connection portion of the locking medical device body, and the second pressing member 1113 moves along the second direction to the locking bracket 10, thus achieving a one-lock-two effect.

[0106] In this embodiment, the first pressing member 1112 and the second pressing member 1113 move in opposite directions under the action of the first adjusting member 112. While achieving one-lock-two, the first pressing member 1112 and the second pressing member 1113 move simultaneously without interference, which can speed up the state switching speed and increase the working reliability of the medical accessory connection device 1. When it is necessary to switch to the release position, the first adjusting member 112 is rotated to reduce the depth of the first adjusting member 112 inserted into the interface seat 1111, thereby reducing the force acting on the first pressing member 1112 and the second pressing member 1113, thereby facilitating the movement of the interface body 111 along the length direction of the bracket 10.

[0107] In some embodiments, the first adjusting member 112 is threadedly engaged with the bracket 10 or the interface body 111 , and the rotation axis of the first adjusting member 112 is parallel to the first direction, so that the first adjusting member 112 has a linear displacement along the first direction during rotation.

[0108] Specifically, the first adjusting member 112 cooperates with the thread of the bracket 10 or the interface body 111. When the first adjusting member 112 is rotated, the first adjusting member 112 can undergo a linear displacement along the first direction. Due to the linear displacement of the first adjusting member 112, the first tightening member 1112 can be driven to undergo a linear displacement along the first direction, thereby achieving locking of the connection part of the medical device body.

[0109] In this embodiment, the arrangement of the first adjusting member 112 can convert the movement of the first adjusting member 112 into linear motion through the rotation conversion of the first adjusting member 112 , thereby achieving good locking reliability and simple and convenient operation.

[0110] For some examples, see Figure 7 The bracket 10 includes a first side wall 101 and a second side wall 102 arranged at intervals along the first direction. The end of the first tightening member 1112 away from the clamping space 1111b passes through the second side wall 102 and extends into the bracket 10. The first adjusting member 112 is penetrated by the first side wall 101 and is threadedly engaged with the first side wall 101. The rotation axis of the first adjusting member 112 is parallel to the first direction.

[0111] Specifically, the first adjusting member 112 cooperates with the thread of the first side wall 101, and the first adjusting member 112 produces a linear displacement along the first direction, driving the first tightening member 1112 to move in the first direction until the first tightening member 1112 locks the connection part of the medical device body. At this time, continue to rotate the first adjusting member 112, and the first tightening member 1112 transmits the force to the interface seat 1111, so that the interface seat 1111 has a tendency to move along the first direction. The end of the interface seat 1111 away from the connection part abuts against the first side wall 101, thereby achieving locking of the bracket 10, so as to achieve synchronous locking of the connection part and the bracket 10.

[0112] In this embodiment, through the threaded engagement of the first adjusting member 112 with the first side wall 101, the first adjusting member 112 can drive the first pressing member 1112 to lock the connection portion and the interface seat 1111 to lock the bracket 10 during rotation. This makes locking the medical accessory connecting device 1 simpler and more convenient, and increases the structural simplicity of the medical accessory connecting device 1. In this embodiment, there is no need for a second pressing member 1112, and a one-lock-two mechanism can be achieved.

[0113] For some examples, see Figure 8 The surface of the first adjusting member 112 used to contact the first tightening member 1112 is the first end face 112a, and the size of the first end face 112a along the length direction of the bracket 10 is not less than the movement stroke of the first tightening member 1112 following the interface seat 1111 along the length direction of the bracket 10.

[0114] For example, the periphery of the first end surface 112a is circular, and the outer diameter of the first end surface 112a is no less than the travel of the first pressing member 1112 along the length of the bracket 10 following the interface seat 1111. The circular periphery of the first end surface 112a facilitates stable contact between the first adjusting member 112 and the first pressing member 1112.

[0115] It is understood that the first adjusting member 112 is threadedly engaged with the bracket 10, and the first adjusting member 112 does not move along the length direction of the bracket 10. In this embodiment, the movement of the interface body 111 along the length direction of the bracket 10 is achieved by the movement of the first pressing member 1112 and the interface seat 1111 relative to the first adjusting member 112.

[0116] Specifically, the first pressing member 1112 moves along the first end surface 112 a to achieve movement in the length direction relative to the bracket 10 .

[0117] In this embodiment, the partial dimension of the first end surface 112a along the length direction of the bracket 10 covers the entire movement stroke of the first tightening member 1112 along the length direction of the bracket 10, so that during the movement of the first tightening member 1112 along the length direction of the bracket 10, the first adjusting member 112 always maintains contact with the first tightening member 1112, thereby increasing the movement reliability. Moreover, no matter what position the first tightening member 1112 is in, the first adjusting member 112 can transmit the force to the first tightening member 1112 through contact, thereby realizing the switching between the locking position and the release position, and the medical accessory connecting device 1 has high operational reliability.

[0118] For some examples, see Figure 8 A first slide groove 1111c is provided on the groove wall of the installation groove 1111a close to the first side wall 101, and a second slide groove 102a is provided on the second side wall 102. Both the first slide groove 1111c and the second slide groove 102a extend along the length direction of the bracket 10. The first adjusting member 112 is passed through the first slide groove 1111c, and a part of the first tightening member 1112 is passed through the second slide groove 102a.

[0119] When the first adjusting member 112 is in the releasing position, the interface seat 1111 can slide relative to the first adjusting member 112 through the first sliding groove 1111 c , and the first pressing member 1112 can slide relative to the second sliding groove 102 a .

[0120] That is to say, the first adjusting member 112 does not move along the length direction of the bracket 10, and the interface seat 1111 can slide along the first sliding groove 1111c, thereby sliding relative to the first adjusting member 112 to achieve position adjustment.

[0121] Specifically, the first sliding groove 1111c and the second sliding groove 102a can provide movement space and a guiding function for the first adjusting member 112 and the first pressing member 1112 to move in the length direction relative to the bracket 10.

[0122] Specifically, in the release position, by applying force to the interface seat 1111, the interface seat 1111 drives the first tightening member 1112 located therein to move along the length direction of the bracket 10, and the first tightening member 1112 moves relative to the second slide groove 102a. The first slide groove 1111c of the mounting groove 1111a of the interface seat 1111 provides a moving space for the interface seat 1111, thereby realizing the movement of the first adjustment member 112 relative to the first slide groove 1111c.

[0123] In this embodiment, the setting of the first slide groove 1111c and the second slide groove 102a can provide guidance and movement space for the movement of the first adjusting member 112 and the first tightening member 1112, while limiting the movement range of the first adjusting member 112 and the first tightening member 1112, thereby increasing operational safety and reliability, so as to achieve stable locking of connection parts of different sizes.

[0124] For some examples, see Figure 4 and Figure 5 The second tightening member 1113 is arranged in the interface seat 1111 or in the bracket 10, and the first adjusting member 112 is threadedly matched with the second tightening member 1113. The first adjusting member 112 is used to drive the second tightening member 1113 to move away from the first tightening member 1112 during the process of continuing to rotate after driving the first tightening member 1112 to lock the connection part, thereby making the second tightening member 1113 press against the bracket 10.

[0125] Specifically, in the locked position, the first adjusting member 112 rotates, driving the first pressing member 1112 to move toward the connecting portion until the connecting portion is locked in the clamping space 1111b. The first adjusting member 112 continues to rotate. At this time, since the first pressing member 1112 cannot move further, the force of the first adjusting member 112 is transmitted to the second pressing member 1113 through the thread, driving the second pressing member 1113 to move away from the first pressing member 1112, thereby supporting the bracket 10 and locking the bracket 10 in the installation groove 1111a. In this way, through the rotation of the first adjusting member 112, the first pressing member 1112 locks the connecting portion and the second pressing member 1113 locks the bracket 10, forming a double locking mechanism, which increases the stability and reliability of the medical accessory connecting device 1.

[0126] For some examples, see Figure 4 、 Figure 8 and Figure 11 The medical accessory connecting device 1 includes at least one accessory locking module 12 , which is used to connect the medical accessory to the bracket 10 .

[0127] Specifically, the support is connected to the accessory locking module 12 .

[0128] The specific structure of the accessory locking module 12 is not limited.

[0129] Illustratively, the accessory locking module 12 includes a base 121 and a second adjustment member 122. The base 121 is connected to the bracket 10 and can move along the length of the bracket 10. In other words, the base 121 can be adjusted in position by moving along the length of the bracket 10 to accommodate medical accessories of different specifications and adjust its relative position to the interface module 11.

[0130] The base 121 has a socket 121a for inserting the rod of the medical accessory. At least a portion of the second adjusting member 122 is inserted into the socket 121a, and when inserted to a preset depth, a force is applied to the rod to lock the rod in the socket 121a, wherein the rod is part of the medical accessory.

[0131] It can be understood that the rod body is a part of the medical accessory. The medical accessory here can be a whole rod-shaped, or it can be formed by a combination of the rod body and components of other shapes. The rod body is passed through the socket 121a to achieve the locking of the medical accessory. For example, the medical accessory here can be an accessory with a circular support rod, an accessory with an elliptical support rod, or an accessory with a rectangular support rod.

[0132] Specifically, the rod body is inserted into the socket 121a, and the second adjusting member 122 can be partially or completely inserted into the socket 121a. The second adjusting member 122 is gradually inserted into the socket 121a, contacts the rod body and applies a force to the rod body. When the second adjusting member 122 is inserted to a preset depth, the applied force locks the rod body. Through the locking of the rod body, the base body 121 is also locked on the bracket 10, thereby realizing a stable connection between the medical accessory and the main body of the medical device.

[0133] It should be noted that the preset depth refers to the insertion depth of the second adjusting member 122 when the second adjusting member 122 locks the rod body in the insertion hole 121 a.

[0134] When unlocking is required, the insertion depth of the second adjusting member 122 is reduced to release the lock on the rod body and the seat body 121 , the rod body can be withdrawn from the insertion hole 121 a , and the seat body 121 can move along the length direction of the bracket 10 .

[0135] In this embodiment, the socket 121a provides a space for the rod body of the medical accessory to pass through, and the second adjusting member 122 is used to lock the rod body and the seat body 121, thereby increasing the locking stability of the medical accessory. Moreover, when unlocking is required, it can also be quickly and conveniently disassembled and assembled, and the position of the seat body 121 and the relative position relationship between the accessory locking module 12 and the interface module 11 can be adjusted by moving the seat body 121 in the length direction relative to the bracket 10, thereby facilitating the medical accessory connecting device 1 to flexibly adapt to different medical accessories.

[0136] It is understandable that the cross-sectional shape of the insertion hole 121a is not limited and can be circular, elliptical, square or other shapes, which are not limited here.

[0137] For some examples, see Figure 4 、 Figure 8 and Figure 11The accessory locking module 12 also includes an accessory tightening member 123 arranged in the base body 121. The accessory tightening member 123 is located on the side of the socket 121a facing the bracket 10. The rod body is used to push the accessory tightening member 123 toward the bracket 10 under the action of the second adjusting member 122, and lock the accessory tightening member 123 on the bracket 10.

[0138] Specifically, during the process of gradually inserting the second adjusting member 122 into the socket 121a, the second adjusting member 122 contacts the rod body and generates a force on the rod body. Under the push of this force, the rod body pushes the accessory tightening member 123 toward the bracket 10 until the accessory tightening member 123 is abutted against the bracket 10 and the accessory tightening member 123 cannot move. At this time, the second adjusting member 122 locks the rod body between the second adjusting member 122 and the accessory tightening member 123, and locks the accessory tightening member 123 on the bracket 10.

[0139] In this embodiment, the second adjusting member 122, the rod body and the accessory tightening member 123 cooperate to lock the rod body between the second adjusting member 122 and the accessory tightening member 123, while at the same time bringing the accessory tightening member 123 into close contact with the bracket 10, thereby locking the bracket 10 and increasing the locking stability of the accessory locking module 12.

[0140] For some examples, see Figure 4 、 Figure 8 and Figure 11 The accessory locking module 12 also includes an elastic structure 124, which applies an elastic force to the accessory pressing member 123 toward the bracket 10. The accessory pressing member 123 is pressed against the bracket 10 under the action of the elastic force to generate a damping force when the accessory locking module 12 slides relative to the bracket 10.

[0141] It should be noted that the damping force does not affect the sliding of the base 121 relative to the bracket 10 . The damping force can limit the sliding speed and accuracy of the accessory locking module 12 relative to the bracket 10 , thereby increasing stability.

[0142] Specifically, when locking the medical accessory, the second adjustment member 122 drives the rod toward the accessory locking member and locks the accessory locking member to the bracket 10, thereby locking the rod. At this time, the elastic structure 124 is elastically deformed under force, storing elastic potential energy. After the rod is unlocked, the elastic structure 124 releases the elastic potential energy. Under the action of the elastic force, the accessory pressing member 123 is pressed against the bracket 10. When the base 121 slides relative to the bracket 10, the elastic structure 124 can ensure that a portion of the accessory pressing member 123 is always in contact with the bracket 10. The damping force helps control the speed and accuracy of the base 121 sliding along the bracket 10, reducing the rapid sliding of the accessory locking module 12 due to gravity or inertia, increasing the stability of the accessory locking module 12 sliding relative to the bracket 10, and improving operational accuracy. At the same time, under the action of the elastic structure, the accessory pressing member can always be close to one side of the bracket and away from the insertion hole, so that there is sufficient space in the insertion hole to facilitate the insertion of the medical accessory rod.

[0143] The specific structure of the elastic structure 124 is not limited.

[0144] For example, the elastic structure 124 can be a spring or other element with elastic properties, which is not limited here. For example, the elastic structure 124 is a spring.

[0145] The following is a brief description of the medical accessory connecting device 1 in some embodiments of the present application in conjunction with the accompanying drawings.

[0146] First embodiment:

[0147] See also Figures 1 to 5 The interface module 11 includes an interface body 111, a first adjustment member 112, and an elastic member 113. The bracket 10 includes a first side wall 101 and a second side wall 102 spaced apart from each other. The interface body 111 includes an interface seat 1111, a first tightening member 1112, and a second tightening member 1113. The interface seat 1111 has a mounting groove 1111a and a clamping space 1111b. The bracket 10 is inserted into the mounting groove 1111a. The clamping space 1111b is used to accommodate the connecting portion of the medical device body.

[0148] The first tightening member 1112 is arranged in the interface seat 1111, the elastic member 113 is sleeved on the outer periphery of the first rod segment 11121 of the first tightening member 1112, the second tightening member 1113 is arranged between the first side wall 101 and the second side wall 102 of the bracket 10, the first adjusting member 112 is threadedly engaged with the interface seat 1111 and the second tightening member 1113, and the first side wall 101 and the second side wall 102 of the bracket 10 are both provided with a slide groove 10a, and the slide groove 10a arranged on the second side wall 102 is formed into a second slide groove 102a.

[0149] In the locked position, the first adjusting member 112 is rotated, causing a linear displacement in the first direction, pushing the first pressing member 1112 to move in the first direction toward the connecting portion until the connecting portion is locked in the clamping space 1111b. At this time, the first adjusting member 112 is further rotated, and the first pressing member 1112 cannot move further. The force of the first adjusting member 112 is transmitted to the second pressing member 1113 through the thread, driving the second pressing member 1113 to move in the second direction until it abuts against the second side wall 102, thereby locking the bracket 10. In the locked position, the elastic member 113 is compressed and contracted.

[0150] When in the release position, the first adjusting member 112 is rotated in the opposite direction to release the lock of the connecting part by the first adjusting member 112, and the elastic member 113 releases the elastic potential energy, pushing the boss 11122 of the first tightening member 1112 against the first side wall 101 of the bracket 10. The elastic force of the elastic member 113 generates a damping force on the sliding of the interface body 111 relative to the bracket 10. At this time, the first tightening member 1112 can move in the slide groove 10a of the first side wall 101 along the length direction of the bracket 10, thereby realizing the movement of the interface body 111 along the length direction of the bracket 10, and the first adjusting member 112 can move in the slide groove 10a of the second side wall 102 along the length direction of the bracket 10, and the entire interface module 11 can move along the length direction of the bracket 10 to adjust the position of the interface module 11.

[0151] See also Figure 4 The accessory locking module 12 includes a base 121, a second adjustment member 122, an accessory pressing member 123, and an elastic structure 124. The base 121 is movable along the length of the bracket 10. The base 121 has a socket 121a for inserting the rod of the medical accessory. The accessory pressing member 123 is located on the side of the socket 121a facing the bracket 10. The second adjustment member 122 is inserted into the socket 121a to apply force to the rod and the accessory pressing member 123. The elastic structure 124 applies an elastic force to the accessory pressing member 123 toward the bracket 10.

[0152] When it is necessary to lock the medical accessory, the rod body is inserted into the socket 121a, and the second adjusting member 122 is inserted into the socket 121a. As the depth of the second adjusting member 122 inserted into the socket 121a deepens, the second adjusting member 122 pushes the rod body and then pushes the accessory tightening member 123 toward the bracket 10, until the accessory tightening member 123 is locked on the bracket 10, and the rod body is locked between the accessory tightening member 123 and the second adjusting member 122. At this time, the elastic structure 124 is compressed and contracted.

[0153] When it is necessary to adjust the position of the accessory locking module 12, the depth of the second adjusting member 122 inserted into the socket 121a is reduced to release the lock on the rod body. The elastic structure 124 releases the elastic potential energy, pushing the accessory tightening member 123 to press against the bracket 10, generating a damping force on the accessory locking module 12 relative to the slide groove 10a of the bracket 10, and the accessory locking module 12 slides as a whole relative to the bracket 10 to adjust the position of the accessory locking module 12.

[0154] Second embodiment:

[0155] See also Figures 6 to 8 The interface module 11 includes an interface body 111, a first adjustment member 112, and an elastic member 113. The bracket 10 includes a first side wall 101 and a second side wall 102 spaced apart from each other. The interface body 111 includes an interface seat 1111 and a first tightening member 1112 disposed within the interface seat 1111. The interface seat 1111 has a mounting groove 1111a and a clamping space 1111b. The bracket 10 is inserted into the mounting groove 1111a. The clamping space 1111b is used to accommodate the connecting portion of the medical device body.

[0156] The elastic member 113 is sleeved on the outer periphery of the first rod section 11121 of the first tightening member 1112, and the end of the first tightening member 1112 away from the clamping space 1111b passes through the second side wall 102 and extends into the bracket 10, the first adjusting member 112 is penetrated by the first side wall 101 and is threadedly engaged with the first side wall 101, and the groove wall of the mounting groove 1111a is close to the first side wall 101 and is provided with a first slide groove 1111c, the slide groove 10a of the bracket 10 is provided on the second side wall 102, forming a second slide groove 102a, the first adjusting member 112 is penetrated by the first slide groove 1111c, the first tightening member 1112 is penetrated by the second slide groove 102a, and the end of the first tightening member 1112 away from the connecting portion abuts against the first end face 112a of the first adjusting member 112.

[0157] In the locked position, the first adjusting member 112 is rotated, causing the first adjusting member 112 to undergo linear displacement along the first direction, pushing the first pressing member 1112 to move along the first direction toward the connecting portion until the connecting portion is locked in the clamping space 1111b. At this time, the first adjusting member 112 is further rotated, and the first pressing member 1112 cannot move further. The force of the first adjusting member 112 is transmitted to the interface seat 1111 through the connecting portion, causing the interface seat 1111 to have a tendency to move in the first direction. The end of the interface seat 1111 away from the first pressing member 1112 is pressed against the first side wall 101, thereby locking the bracket 10. In the locked position, the elastic member 113 is compressed and contracted.

[0158] In the release position, the first adjusting member 112 is rotated in the opposite direction to release the lock on the connecting portion by the first adjusting member 112. The elastic member 113 releases its elastic potential energy, pushing the boss 11122 of the first pressing member 1112 against the first side wall 101 of the bracket 10. The elastic force of the elastic member 113 generates a damping force on the sliding of the interface body 111 relative to the bracket 10. At this time, the first pressing member 1112 can move along the longitudinal direction of the bracket 10 in the slot 10a of the first side wall 101, thereby achieving the movement of the interface body 111 along the longitudinal direction of the bracket 10. The first adjusting member 112 and the interface body 111 can slide relative to each other along the second slot 102a. The movement stroke of the first pressing member 1112 along the longitudinal direction of the bracket 10 does not exceed the outer diameter of the first end surface 121a. In this way, the position of the interface module 11 is adjusted.

[0159] See also Figure 8 The accessory locking module 12 includes a base 121, a second adjustment member 122, an accessory pressing member 123, and an elastic structure 124. The base 121 is movable along the length of the bracket 10. The base 121 has a socket 121a for inserting the rod of the medical accessory. The accessory pressing member 123 is located on the side of the socket 121a facing the bracket 10. The second adjustment member 122 is inserted into the socket 121a to apply force to the rod and the accessory pressing member 123. The elastic structure 124 applies an elastic force to the accessory pressing member 123 toward the bracket 10.

[0160] When it is necessary to lock the medical accessory, the rod body is inserted into the socket 121a, and the second adjusting member 122 is inserted into the socket 121a. As the depth of the second adjusting member 122 inserted into the socket 121a deepens, the second adjusting member 122 pushes the rod body and then pushes the accessory tightening member 123 toward the bracket 10, until the accessory tightening member 123 is locked on the bracket 10, and the rod body is locked between the accessory tightening member 123 and the second adjusting member 122. At this time, the elastic structure 124 is compressed and contracted.

[0161] When it is necessary to adjust the position of the accessory locking module 12, the depth of the second adjusting member 122 inserted into the socket 121a is reduced to release the lock on the rod body. The elastic structure 124 releases the elastic potential energy, pushing the accessory tightening member 123 to press against the bracket 10, generating a damping force on the accessory locking module 12 relative to the slide groove 10a of the bracket 10, and the accessory locking module 12 slides as a whole relative to the bracket 10 to adjust the position of the accessory locking module 12.

[0162] Third embodiment:

[0163] See also Figures 9 to 11The interface module 11 includes an interface body 111 and a first adjusting member 112. The bracket 10 includes a first side wall 101 and a second side wall 102 spaced apart from each other. The interface body 111 includes an interface seat 1111, a first tightening member 1112, and a second tightening member 1113. The first tightening member 1112 and the second tightening member 1113 are disposed in the interface seat 1111. The interface seat 1111 has a mounting groove 1111a and a clamping space 1111b. The bracket 10 is inserted into the mounting groove 1111a. The clamping space 1111b is used to accommodate the connecting portion of the medical device body.

[0164] One end of the first adjusting member 112 extends between the first pressing member 1112 and the second pressing member 1113, and simultaneously abuts against the first pressing member 1112 and the second pressing member 1113. The slide groove 10a of the bracket 10 is provided on the second side wall 102, forming a second slide groove 102a, and the second pressing member 1113 is passed through the slide groove 10a.

[0165] When in the locked position, rotate the first adjusting member 112, and the first adjusting member 112 will be displaced along the length direction of the bracket 10, pushing the first tightening member 1112 to move toward the connecting part along the first direction, and the second tightening member 1113 to move toward the first side wall 101 along the second direction, until the first tightening member 1112 locks the connecting part, and the second tightening member 1113 abuts against the second side wall 102 to achieve double locking of the connecting part and the bracket 10.

[0166] When in the release position, the first adjusting member 112 is rotated in the opposite direction to release the lock of the first adjusting member 112 on the connecting portion. The second tightening member 1113 can move along the slide groove 10a of the second side wall 102, driving the first adjusting member 112, the first tightening member 1112 and the interface seat 1111 to move, thereby adjusting the position of the interface module 11.

[0167] See also Figure 11 The accessory locking module 12 includes a base 121 and a second adjustment member 122. The base 121 is movable along the length of the bracket 10. The base 121 has a socket 121a for the rod of the medical accessory to pass through. At least a portion of the second adjustment member 122 is inserted into the socket 121a. When the rod is inserted to a predetermined depth, the second adjustment member 122 applies a force to the rod to lock it in the socket 121a.

[0168] Of course, the accessory locking module 12 may also include Figure 7The accessory pressing member 123 and the elastic structure 124 are shown. That is, the structure of the accessory locking module 12 in the third embodiment can be the same as the structure of the accessory locking module 12 in the second embodiment. Specifically, under this structure, the base 121 can move along the length direction of the bracket 10. The base 121 has a socket 121a for the rod of the medical accessory to pass through. The accessory pressing member 123 is located on the side of the socket 121a facing the bracket 10. The second adjustment member 122 is inserted into the socket 121a to apply force to the rod and the accessory pressing member 123. The elastic structure 124 applies an elastic force to the accessory pressing member 123 toward the bracket 10.

[0169] When it is necessary to lock the medical accessory, the rod body is inserted into the socket 121a, and the second adjusting member 122 is inserted into the socket 121a. As the depth of the second adjusting member 122 inserted into the socket 121a deepens, the second adjusting member 122 pushes the rod body and then pushes the accessory tightening member 123 toward the bracket 10, until the accessory tightening member 123 is locked on the bracket 10, and the rod body is locked between the accessory tightening member 123 and the second adjusting member 122. At this time, the elastic structure 124 is compressed and contracted.

[0170] When it is necessary to adjust the position of the accessory locking module 12, the depth of the second adjusting member 122 inserted into the socket 121a is reduced to release the lock on the rod body. The elastic structure 124 releases the elastic potential energy, pushing the accessory tightening member 123 to press against the bracket 10, generating a damping force on the accessory locking module 12 relative to the slide groove 10a of the bracket 10, and the accessory locking module 12 slides as a whole relative to the bracket 10 to adjust the position of the accessory locking module 12.
