[0002] In laparoscopic thyroid surgery, the instruments used mainly include operating instruments and auxiliary instruments. Operating instruments, such as separation forceps, are held and operated by the surgeon; auxiliary instruments, such as electronic laparoscopes, retractors, spreaders, etc., are manually held by assistants and are not moved frequently.

[0003] In actual surgery, the surgeon needs to hold the operating instruments in the air for a long time and manually pull the tissue. The assistant also needs to hold some instruments still to assist the surgeon in the operation. However, a long operation lasting 1-2 hours can easily cause upper limb fatigue of the surgeon and the assistant. The surgeon's operating stability will be affected, and the assistant's operation may block the lens or instruments, affecting the surgeon's field of view. Therefore, there is an urgent need for a support device to assist in supporting the instruments used in the operation, relieve the pressure on the surgeon and the assistant, make long-term operation more convenient, and reduce upper limb fatigue caused by long-term surgery.

DETAILED DESCRIPTION

[0018] The present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than to limit the present disclosure.

[0019] In order to simplify the drawings, only the parts related to the disclosure are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0020] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this disclosure can be understood according to specific circumstances.

[0021] In the present disclosure, unless otherwise expressly specified and limited, a first feature being “above” or “below” a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being “above”, “above”, and “above” a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0022] In the description of this embodiment, terms such as "up", "down", "left", and "right" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present disclosure.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] like Figure 1~Figure 2As shown, it shows a laparoscopic thyroid surgery auxiliary support device in an embodiment of the present disclosure. In some examples, the first ball joint seat 1 is composed of a ball head and a spherical shell. The ball head can automatically rotate within the spherical shell to a certain extent. A first limiting groove 11 is provided on the top of the first ball joint seat 1. The first limiting groove 11 is used to place operating instruments used by the surgeon during surgery, or auxiliary instruments that the assistant needs to support. The first clamping plates 12 located on both sides of the first limiting groove 11 can clamp the front end cylindrical part of the instrument to ensure that the instrument does not separate from the first ball joint seat 1.

[0025] Taking the separation forceps as an example, when the operator picks up the separation forceps and prepares to start the operation, first put the front cylindrical part of the separation forceps into the first limiting groove 11 on the top of the first ball joint seat 1, and then manually operate the adjustment mechanism on the first ball joint seat 1 to move the two first clamps 12 toward each other and gradually approach the handle of the separation forceps. When the clamps touch the handle of the separation forceps, continue to fine-tune to ensure that the clamps can stably clamp the separation forceps so that it will not loosen during operation. Or a spring is set between the two first clamps 12, and the elastic force of the spring is used to clamp the shaft of the separation forceps. Since the separation forceps are stably supported by the first ball joint seat 1, the operator does not need to hold it in the air all the time to bear its weight, which greatly reduces the fatigue of the upper limbs, allowing the operator to focus more on the operation and improve the accuracy of the operation.

[0026] Similarly, when the assistant uses the retractor to assist in exposing the surgical field of view, the assistant places the retractor in the first limiting groove 11 of another first ball joint seat 1, and fixes it by adjusting the first clamping plate 12. The assistant only needs to make slight adjustments to the retractor occasionally, without having to hold it tightly to maintain its position, which effectively relieves the assistant's upper limb pressure. Moreover, since the position of the retractor is fixed by the supporting device, the situation in which the assistant's fatigue causes the retractor position to shift and block the lens or instrument is reduced, thereby ensuring a clear field of view for the surgeon.

[0027] For example, Figure 1As shown, the advantage of such a setting is that it reduces fatigue of the upper limbs: the support of the surgical instrument by the first ball joint seat 1 eliminates the need for the surgeon and the assistant to hold the instrument in the air for a long time, which reduces the fatigue of the upper limbs during long-term surgery, allowing them to maintain better physical strength and operating conditions during the operation, and improve the quality and safety of the operation. Improve operational stability: The surgical instrument is stably clamped by the first splint 12, avoiding the instability of the instrument caused by hand fatigue or shaking, and the surgeon can control the movement of the instrument more accurately. Optimize visual field conditions: For auxiliary instruments used by assistants, the support device fixes their position, reducing the probability of blocking the lens or other instruments due to improper operation of the assistant, providing the surgeon with a clearer and more stable surgical field of view, which is conducive to the smooth progress of the operation. Flexible adaptability: Multiple first ball joint seats 1 are arranged at intervals, and their positions and spacings can be flexibly adjusted according to the specific needs of the surgical operation to adapt to the support requirements of different types of surgical instruments and meet the changes in the layout of instruments in different surgical steps, thereby improving the versatility and practicality of the support device in various laparoscopic thyroid surgery scenarios.

[0028] like Figure 3~Figure 5 As shown, it shows a laparoscopic thyroid surgery auxiliary support device in an embodiment of the present disclosure. In some examples, medical staff can first adjust the height of the lifting platform 2 according to the patient's body position and the expected position of the surgical operation. For example, by operating the electric button or manual rocker on the lifting platform 2, the lifting platform 2 is raised or lowered to a suitable vertical position. Then, according to the use requirements of different surgical instruments and the operating habits of the surgeon and the assistant, the horizontal position of the first ball joint seat 1 is adjusted. Since the guide sleeve 22 can slide back and forth on the base 21, when it is necessary to move the first ball joint seat 1 supporting the separation forceps forward, the medical staff can push the guide sleeve 22. The guide column 13 at the bottom of the first ball joint seat 1 is vertically lifted and set in the guide sleeve 22, and the height of the first ball joint seat 1 can be fine-tuned again to adjust the first ball joint seat 1 to a position that is more convenient for the surgeon to operate. If it is found that the position is not suitable during the operation, it can be fine-tuned again.

[0029] In some examples, when the operator needs to adjust the height of the separation forceps, the operator can directly press down or lift up the separation forceps to make the guide column 13 move vertically up and down in the guide sleeve 22. For example, when operating deep thyroid tissue, the operator gently presses down the separation forceps, and the guide column 13 descends in the guide sleeve 22, and the separation forceps lowers its height and reaches the surgical site more deeply, while the first ball joint seat 1 always stably supports the separation forceps to ensure the stability of the operator's operation. Similarly, when using the retractor, the assistant can also flexibly adjust the height and front and back position of the retractor in a similar way according to the need to expose the surgical field.

[0030] For example, Figure 3As shown, the advantage of such a setting is that it can meet the needs of surgery: the lifting platform 2 and the slidable and lifting guide column 13 guide sleeve 22 structure, as well as the free rotation of the first ball joint seat 1, enable the surgical instrument to flexibly adjust its position in three-dimensional space, better adapt to the physical characteristics, surgical positions and various complex surgical operation requirements of different patients, ensure that the surgical instrument is always in the most convenient position for operation, and improve the convenience and accuracy of operation. Enhanced operational flexibility: The operator and the assistant can adjust the height and front and rear position of the instrument in real time and conveniently during the operation. This flexibility satisfies the free adjustment of the instrument and facilitates various operations.

[0031] like Figure 3~Figure 5 As shown, it shows a laparoscopic thyroid surgery auxiliary support device in an embodiment of the present disclosure. In some examples, when the height of the separation forceps needs to be fine-tuned, an assistant or a circulating nurse can operate the first rotating rod 23. The first rotating rod 23 is located at the first limiting hole 221 on the side wall of the guide sleeve 22, and extends through the first limiting hole 221 into the first groove 131 on the side wall of the guide column 13. When the first rotating rod 23 is rotated, the first gear 231 installed on the first rotating rod 23 rotates accordingly. Since the first gear 231 is meshed with the first rack 132 on the inner wall of the first groove 131, the rotation of the first gear 231 will drive the first rack 132 to move. Because the first rack 132 is fixed to the inner wall of the first groove 131 of the guide column 13, the movement of the first rack 132 causes the guide column 13 to rise and fall vertically together with the first ball joint seat 1 installed on the top thereof. During the entire surgical process, according to different operation stages and requirements, it may be necessary to adjust the height of the first ball joint seat 1 multiple times. Each adjustment can be achieved simply and quickly by rotating the first rotating rod 23.

[0032] For example, Figure 4As shown, the advantage of such a setting is that it is convenient for height adjustment: the height adjustment of the guide column 13 and the first ball joint seat 1 is realized through the meshing transmission of the first gear 231 and the first rack 132. Moreover, compared with the manual direct lifting of the guide column 13, this transmission method can more accurately control the height change, meet the needs of subtle adjustment of the instrument height during the operation, help improve the accuracy of the surgical operation, and reduce the operation errors caused by inappropriate instrument height. Convenient operation: the guide column 13 and the first ball joint seat 1 can be lifted and lowered by simply rotating the first rotating rod 23, which is simple and convenient to operate. During the operation, the assistant or the circulating nurse can quickly respond to the needs of the operator and adjust the height of the instrument in time without complicated operation steps, saving time and improving the fluency of the surgical operation. Enhanced stability: The gear rack transmission structure has good self-locking performance. When the first rotating rod 23 stops rotating, the guide column 13 can be stably maintained at the current height position, and the height will not change due to vibration or slight force on the instrument during the operation. This ensures the stability of the surgical instrument during the operation, provides reliable support for the operator, and helps to improve the safety of the surgical operation.

[0033] like Figure 1~Figure 4 As shown, it shows an auxiliary support device for laparoscopic thyroid surgery in an embodiment of the present disclosure. In some examples, when adjusting the height of the separation forceps, when the appropriate height is reached, the assistant presses the first rotating rod 23 toward the guide column 13. At this time, the spherical protrusion 232 of the first rotating rod 23 located at the center of the inner end surface of the first groove 131 is elastic and deforms to a certain extent after being subjected to pressure, and is smoothly inserted into one of the spherical limiting grooves 133 arranged vertically on the inner wall of the first groove 131. In this way, the guide column 13 is firmly fixed at the current position of the guide sleeve 22, and the separation forceps can also be maintained at the adjusted height, providing stable support for the operator. If the height of the separation forceps needs to be adjusted again, the assistant only needs to pull the first rotating rod 23 outward with a little force to make the spherical protrusion 232 disengage from the current spherical limiting groove 133, and then rotate the first rotating rod 23 again to adjust the height. After the new height is determined, the first rotating rod 23 is pressed again to allow the spherical protrusion 232 to fit into the corresponding spherical limiting groove 133, thereby completing the re-fixation of the guide post 13. During the entire surgical procedure, such adjustment and fixing operations may be performed multiple times according to the requirements for the height of the separation forceps at different operation stages.

[0034] For example, Figure 4As shown, the advantage of such a setting is that the fixing stability is enhanced: the engagement structure of the spherical protrusion 232 and the spherical limiting groove 133 provides an additional fixing method for the guide column 13 in the guide sleeve 22, thereby enhancing the fixing stability of the guide column 13. During the operation, even if it is slightly vibrated by the outside world or subjected to a small force during the operation of the instrument, the guide column 13 can be firmly maintained at the set height, ensuring the stability of the position of the surgical instrument, reducing the interference caused by the change of the instrument position to the surgical operation, and improving the safety and accuracy of the operation. Convenient positioning and adjustment: This design makes the positioning operation of the guide column 13 after the height adjustment very convenient. After adjusting the height through the first rotating rod 23, the guide column 13 can be fixed by simply pressing the first rotating rod 23. Conversely, the first rotating rod 23 can be pulled outward to release the fixation for re-adjustment. The operation process is simple and intuitive, without the need for additional complex tools or operation steps, which facilitates the assistant to quickly respond to the operator's needs for instrument height adjustment and fixation during the operation, thereby improving the efficiency of the surgical operation. Adapt to various height requirements: The multiple spherical limit grooves 133 arranged vertically can adapt to the fixing requirements of the guide column 13 at different height positions. No matter to what height the guide column 13 rises or falls, it can be fixed by engaging the spherical protrusion 232 with the corresponding spherical limit groove 133, which meets the diverse requirements for the height of surgical instruments due to different operation stages during the operation, and enhances the flexibility and adaptability of the support device. Protect the transmission structure: The elastic design of the spherical protrusion 232 protects the transmission structure of the first gear 231 and the first rack 132 to a certain extent. When the guide column 13 is subjected to unexpected external force, the spherical protrusion 232 can absorb part of the impact force through its own deformation, avoid the external force directly acting on the gear rack structure, reduce the risk of gear rack damage due to external force impact, extend the service life of the transmission structure, and thus improve the reliability and durability of the entire support device.

[0035] like Figure 1~Figure 5 As shown, it shows a laparoscopic thyroid surgery auxiliary support device in an embodiment of the present disclosure. In some examples, the first elastic member 233 can be a spring, and the spring provides a force for the spherical protrusion 232 to always be stuck in the spherical limit groove 133. When the height of the first ball joint seat 1 needs to be adjusted, it is necessary to overcome the elastic force of the spring, pull the first rotating rod 23 outward, so that the spherical protrusion 232 is disengaged from the current spherical limit groove 133, and then rotate the first rotating rod 23 to adjust the height, which is more convenient to use. The first retaining ring 234 limits the movement of the first rotating rod 23 to prevent the first rotating rod 23 from accidentally disengaging from the first limit hole 221.

[0036] In addition, the width of the first gear 231 and the first rack 132 can be set to be larger than the movement required for the spherical protrusion 232 to fit into the spherical stop groove 133, so that the first gear 231 and the first rack 132 will be relatively displaced, but will not be completely separated. When the first rotating rod 23 needs to be reset, the first gear 231 and the first rack 132 will not interfere with each other and cannot be aligned, which makes the overall use more convenient. Lubricating oil can be regularly applied between the first gear 231 and the first rack 132 to ensure smooth movement.

[0037] For example, Figure 4 As shown, the advantage of such a configuration is that the operation is more convenient: the first elastic member 233 can automatically reset the first rotating rod 23 to the position where the spherical protrusion 232 is inserted into the spherical stop groove 133, and no manual adjustment is required. It is only necessary to pull the first rotating rod 23 outward to disengage the spherical protrusion 232 from the spherical stop groove 133, thus saving operation time. In addition, the configuration of the first retaining ring 234 prevents the position of the first rotating rod 23 from being offset or accidentally disengaged, making the use smoother and more reliable.

[0038] like Figure 5 As shown, it shows a laparoscopic thyroid surgery auxiliary support device in an embodiment of the present disclosure. In some examples, the first limiting rod 223 is arranged on the first mounting plate 222, and the first mounting plate 222 is located on one side of the second rack 211. When the first limiting rod 223 is pushed, the latching tooth 224 close to the end of the second rack 211 will gradually approach the second rack 211. When the latching tooth 224 is engaged with the second rack 211, the guide sleeve 22 is fixed on the base 21. Due to the complexity of the thyroid surgery operation, it may be necessary to adjust the front and rear positions of the surgical instruments at different stages. At this time, first pull the first limiting rod 223 to disengage the latching tooth 224 from the engagement with the second rack 211, and then slide the guide sleeve 22 forward on the base 21 to a suitable position, and push the first limiting rod 223 again to re-engage the latching tooth 224 with the second rack 211 to complete the re-fixation of the guide sleeve 22. For example, Figure 5 As shown, the advantages of such a setting are flexible and stable positioning: by engaging or disengaging the engaging teeth 224 of the first limiting rod 223 with the second rack 211, the position of the guide sleeve 22 on the base 21 can be flexibly adjusted and stably fixed. Medical staff can quickly move the guide sleeve 22 to a suitable position and firmly fix it according to the actual needs of the operation, ensuring that the surgical instruments are always in a position that is convenient for operation, thereby improving the convenience and accuracy of the surgical operation. Easy to operate: The left and right movement of the first limiting rod 223 is simple and intuitive, and medical staff can easily fix and release the guide sleeve 22 without the help of complex tools. During the operation, it can quickly respond to the needs of the surgical operation for adjusting the position of the instrument, saving time and improving surgical efficiency.

[0039] like Figure 5~Figure 7 As shown, it shows a laparoscopic thyroid surgery auxiliary support device in an embodiment of the present disclosure. In some examples, since the first limiting rod 223 is located at the bottom of the guide sleeve 22, it is not convenient to directly push the first limiting rod 223 to move at this position. For the convenience of operation, a second limiting rod 227 is also provided. When the second limiting rod 227 is pushed to move forward, the short rod 228 connected to the second limiting rod 227 moves in the inclined guide groove 226 of the second mounting plate 225. Due to the inclined design of the inclined guide groove 226, the movement of the short rod 228 will drive the second mounting plate 225 and the first limiting rod 223 connected thereto to move as a whole. As the first limiting rod 223 moves, the latching teeth 224 at one end thereof close to the second rack 211 gradually disengage from the latching connection with the second rack 211. At this time, the guide sleeve 22 can be easily slid forward to a suitable position on the base 21. When the guide sleeve 22 reaches the desired position, the second limiting rod 227 is moved in the opposite direction to move it backward. The short rod 228 moves in the reverse direction in the inclined guide groove 226, driving the second mounting plate 225 and the first limiting rod 223 to move back, so that the latching tooth 224 is again latched onto the second rack 211, thereby firmly fixing the guide sleeve 22 at the new position.

[0040] For example, Figure 5 As shown, the advantage of such a setting is that the operation mode is optimized: through the clever cooperation of the second limit rod 227, the short rod 228 and the inclined guide groove 226, the left and right movement of the first limit rod 223 is converted into the forward and backward movement of the second limit rod 227. There is no need to reach to the bottom of the guide sleeve 22 to grope and push the first limit rod 223, and the second limit rod 227 exposed outside can be directly pushed. This operation mode is more convenient, the operation difficulty is reduced, and the adjustment efficiency is improved.

[0041] like Figure 5~Figure 7 As shown, it shows a laparoscopic thyroid surgery auxiliary support device in an embodiment of the present disclosure. In some examples, the second elastic member 229 can be a spring. When the guide sleeve 22 needs to be moved, the second limit rod 227 is pressed, and the second limit rod 227 drives the first limit rod 223 to move through the short rod 228. In this process, it is necessary to overcome the elastic force of the second elastic member 229 to put it in a compressed state. After adjusting the guide sleeve 22 to a suitable position, the second limit rod 227 is released, and the second elastic member 229 immediately restores the force on the first limit rod 223, so that the locking tooth 224 is tightly engaged with the second rack 211 again, and the guide sleeve 22 is fixed again.

[0042] For example, Figure 6As shown, the advantage of such a setting is that the fixing stability is enhanced: the additional force provided by the second elastic member 229 makes the engagement between the latching tooth 224 and the second rack 211 more stable. This effectively avoids the loosening of the guide sleeve 22 due to factors such as vibration during the operation and external forces generated by the operation of the instrument, ensures that the surgical instrument always remains in the predetermined position, provides stable and reliable support for the surgical operation, and helps to improve the accuracy and safety of the operation. Easy to operate and position: the second elastic member 229 can automatically reset the first limit rod 223, without the need to waste time pulling the second limit rod 227, making the operation simpler and more convenient, and the position of the guide sleeve 22 can be quickly adjusted according to the actual needs of the operation.

[0043] like Figure 7 As shown, it shows an auxiliary support device for laparoscopic thyroid surgery in one embodiment of the present disclosure. In some examples, the ball head of the first ball joint seat 1 can achieve a certain angle of rotation, thereby changing the direction of the surgical instrument. Some auxiliary instruments, such as electronic laparoscopes, do not need to be moved frequently. At this time, it is necessary to limit the rotation of the first ball joint seat 1 to make it more stable. At this time, the sliding block 153 can be pushed to slide along the symmetrical inclined surfaces 152 on the two second clamps 15. As the sliding block 153 moves, it will push the two second clamps 15 away from each other, overcome the elastic force of the third elastic member 151, and thus release the restriction on the rotation of the ball head. At this time, the assistant can easily rotate the ball head of the first ball joint seat 1 to adjust the angle of the electronic laparoscope. When the proper angle is adjusted, the sliding block 153 is released, and the third elastic member 151 immediately takes effect, so that the two second clamping plates 15 move closer together under the action of elastic force, clamp the ball head again, and fix the electronic laparoscope at the adjusted angle position, so that even if it is accidentally touched, the angle and position will not be shifted, and the functions it produces, such as the field of view, will not change, and will not affect the operator's operation.

[0044] For example, Figure 7As shown, the advantage of such a setting is that stability is enhanced: the force provided by the third elastic member 151 enables the second splint 15 to firmly and stably clamp the ball head, ensuring that the surgical instrument will not be offset at an angle due to external force or vibration during use. Even during long-term surgical operations, the surgical instrument can always remain at the set angle position, providing reliable support for surgical operations. Flexible degree adjustment and fixation: Through the coordinated action of the sliding block 153, the second splint 15, the third elastic member 151 and the inclined surface 152, flexible control of the rotation of the ball head of the first ball joint seat 1 is achieved, so that the angle of the surgical instrument can be adjusted, and it can be firmly fixed after adjustment, reducing the difficulty of operation caused by inappropriate instrument angle. Convenient operation: This structural design makes the adjustment operation of the surgical instrument angle very simple. The operator or assistant only needs to push the sliding block 153 to unlock and lock the angle adjustment, without the need for complex tools or cumbersome operating steps, and can quickly respond to the need for instrument angle adjustment during surgery, thereby improving surgical efficiency.

[0045] like Figure 1 As shown, it shows an auxiliary support device for laparoscopic thyroid surgery in an embodiment of the present disclosure. In some examples, taking the separation forceps as an example, when the separation forceps is placed on the first ball joint seat 1, its shaft part is placed in the first limiting groove 11 and is clamped and fixed by two first clamps 12. At the same time, the handle part of the separation forceps is supported by the second limiting groove 161 on the bracket 16. The first limiting groove 11 and the first clamp 12 ensure the stability of the separation forceps shaft, while the second limiting groove 161 on the bracket 16 provides additional support for the separation forceps handle from below to prevent the separation forceps from shaking or shifting due to long-term operation or uneven force.

[0046] For another example, for an electronic laparoscope, its cable connection part may be heavy, which may easily cause the laparoscope to feel like it is falling during use, affecting the field of view. At this time, the main body of the electronic laparoscope is placed in the first limiting groove 11 and fixed by the first clamping plate 12, while its cable connection part can be placed in the second limiting groove 161 of the bracket 16. The second limiting groove 161 can not only support the weight of the cable part and reduce the burden on the main body of the laparoscope, but also prevent the cable from swinging randomly to interfere with the surgical operation, ensuring that the electronic laparoscope is always at a stable observation angle, providing the surgeon with a clear and stable surgical field of view.

[0047] For example, Figure 1As shown, the advantage of such a configuration is that the stability of the instrument is enhanced: the configuration of the bracket 16 and the second limiting groove 161 provides an additional support point for the surgical instrument from below, and works together with the first limiting groove 11 and the first splint 12 to enhance the stability of the surgical instrument on the first ball joint seat 1. This helps to reduce the shaking and displacement of surgical instruments during long-term operation, ensure the accuracy of surgical operations, and reduce surgical risks caused by unstable instruments. Disperse the force on the instrument: For some surgical instruments with special structures or heavier parts, such as electronic laparoscopes with heavier cables, the second limiting groove 161 of the bracket 16 can share part of the weight of the instrument, making the force on the instrument more uniform. This is not only conducive to maintaining the normal use of the instrument, but also can extend the service life of the instrument and reduce damage to the instrument due to excessive local force.
