Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to an auxiliary supporting device for orthopedic arthroscopic surgery and a method of using the same. Background Art

[0002] Orthopedic arthroscopic surgery is an important minimally invasive surgical method that uses arthroscopy, an endoscopic technique, to observe and perform surgical treatment inside the joint. In orthopedic arthroscopic surgery, auxiliary support devices play a vital role. The use of auxiliary support devices in orthopedic arthroscopic surgery can greatly shorten the operation time and reduce the pain of patients.

[0003] Existing auxiliary support devices use clamping and fixing frames to fix the surgical site of the patient to ensure stability during the operation. At the same time, in order to meet different surgical sites and surgical requirements, existing auxiliary support devices usually have an adjustment function, which adjusts parameters such as height and angle to put the surgical site in the best observation and treatment position. However, in the prior art, medical staff are usually required to frequently manually adjust the optimal observation and treatment position of the auxiliary support device, which greatly increases the time of the operation.

[0004] In summary, how to solve the problem in the prior art that medical staff usually need to frequently manually adjust the optimal observation and treatment position of the auxiliary support device, which greatly increases the operation time has become a difficult problem that needs to be urgently solved in this field. Therefore, it is necessary to propose an auxiliary support device for orthopedic arthroscopic surgery and a method of using the same. Summary of the invention

[0005] To solve the above problems, the present invention provides an auxiliary support device for orthopedic arthroscopic surgery and a method of using the same, which can accurately and quickly adjust the surgical site to the optimal observation and treatment position through an automated adjustment mechanism, and can also quickly and accurately adjust the arthroscope to the optimal observation position of the surgical site, thereby shortening the operation time and alleviating the patient's pain.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an auxiliary support device for orthopedic arthroscopic surgery, comprising a base and a controller; a fixed frame is fixedly connected to the top of the base, and sliding grooves are symmetrically opened on the side walls of the two length directions of the fixed frame.

[0007] A limiting groove is provided on the inner bottom wall of the fixed frame, and a driving block is slidably fitted on the limiting groove. The outer walls of the driving block in both width directions are symmetrically and fixedly connected with sliding rods. The sliding rods all penetrate the adjacent side walls of the fixed frame and are slidably fitted with the adjacent sliding grooves. A connecting rod is hinged at one end of the sliding rod away from the driving block; a nut hole is provided on the driving block.

[0008] A rotating shaft is provided on the top of the base, and both ends of the rotating shaft are rotatably connected with fixed blocks, and the bottom of the fixed block is fixedly connected to the top of the base; a rotating plate is fixedly connected to the rotating shaft, and the end of the connecting rod away from the sliding rod is hinged to the side wall of the rotating plate.

[0009] A supporting assembly for supporting the patient's legs is arranged on the rotating plate; a clamping assembly for supporting the arthroscope is also arranged on the top of the base.

[0010] The technical principles of the above scheme are as follows:

[0011] By controlling the movement of the driving block on the limit slot, since the connecting rod is hinged to the sliding rod and the rotating plate, when the driving block moves, the sliding rod drives the connecting rod to change the angle between the rotating plate and the connecting rod, and the connecting rod drives the rotating plate to rotate around the rotating axis, thereby changing the angle of the supporting assembly, and realizing the adjustment of the rotating angle of the rotating plate and the connecting rod. The supporting assembly then changes the angle between the patient's thigh and calf to realize automatic adjustment of the optimal observation and treatment position of the auxiliary support device.

[0012] During the operation, medical staff can adjust the angle of the support component through the controller according to the surgical site and surgical requirements to put the surgical site in the best observation and treatment position; the clamping component can clamp the arthroscope to ensure the stability of the arthroscope during the operation.

[0013] The above scheme has the following beneficial effects:

[0014] 1. The auxiliary support device of the present invention accurately controls the movement of the driving block on the limit groove through a controller, thereby realizing the automatic adjustment function of the auxiliary support device; medical staff can quickly adjust the surgical site to the optimal observation and treatment position without frequent manual adjustments, thereby significantly shortening the operation time and improving the operation efficiency.

[0015] 2. During the operation, the auxiliary support device of the present invention ensures the stability of the surgical site through precise automatic adjustment and stable support components; this stability not only helps the doctor to perform precise surgical operations, but also reduces the pain of the patient during the operation.

[0016] 3. The auxiliary support device of the present invention reduces the number of manual adjustments and the risks that may be caused by improper operation, thereby further improving the safety and reliability of the operation.

[0017] Furthermore, the driving assembly includes a driving member, which is fixedly connected to the top of the base, and the controller is used to control the opening and closing of the driving member; a screw is coaxially fixedly connected to the output shaft of the driving member, the screw passes through the side wall of the fixed frame and is rotatably connected to the side wall of the fixed frame; the screw and the nut hole are threadedly matched.

[0018] Beneficial effects: The output shaft of the driving member can drive the screw to rotate, and through the cooperation between the screw and the nut hole in the driving block, the driving block can move in the limiting groove, which is convenient for achieving subsequent effects.

[0019] Furthermore, the supporting assembly comprises a thigh support plate and a calf support plate, the thigh support plate and the calf support plate are hinged, the thigh support plate is fixedly connected to the side wall of the rotating plate, and the calf support plate is fixedly connected to the connecting rod adjacent thereto.

[0020] Beneficial effects: The stable support also reduces the pain and discomfort of the patient during the operation and improves the patient's surgical experience. At the same time, driven by the driving member, and with the cooperation of the thigh support and the calf support with the rotating plate and the connecting rod, it is possible to change the angle between the thigh support and the calf support, thereby changing the angle of the patient's legs and realizing the function of automatic adjustment of the patient's leg support.

[0021] Furthermore, the clamping assembly includes an axle and a first electric telescopic rod, the first electric telescopic rod is fixedly connected to the top of the base, the controller is used to control the extension and retraction of the output shaft of the first electric telescopic rod, and the axle is rotatably connected to the top of the base; a rack is fixedly connected to the output shaft of the first electric telescopic rod; a gear is coaxially fixedly connected to the end of the axle away from the base, and the gear and the rack are meshed; a second electric telescopic rod is coaxially fixedly connected to the top of the gear, and the controller is used to control the extension and retraction of the output shaft of the second electric telescopic rod; the output shaft of the second electric telescopic rod is coaxially fixedly connected to a rotating arm, and a first circular plate is fixedly connected to the end of the rotating arm away from the second electric telescopic rod, a second circular plate is rotatably connected to a side wall of the first circular plate away from the rotating arm, and a U-shaped clamp is fixedly connected to a side wall of the second circular plate away from the first circular plate.

[0022] Beneficial effects: The clamping assembly enables the arthroscope to maintain a stable position and angle during surgery, and also improves the accuracy and safety of the surgery. At the same time, the first airbag on the inner wall of the U-shaped clamp can further clamp the arthroscope to prevent it from shaking during surgery.

[0023] Furthermore, a first airbag is fixedly connected to the inner wall of the U-shaped clamp, and an input end of the first airbag is connected to an air path system.

[0024] Beneficial effect: The first airbag can expand as the U-shaped clamp is clamped, thereby more tightly fixing the arthroscope. This design improves the stability and reliability of clamping and avoids the problem of affecting the surgical effect due to the shaking of the arthroscope.

[0025] Furthermore, a second airbag is fixedly connected to the side wall of the driving block close to the driving member, a side wall of the second airbag away from the driving block is fixedly connected to the inner wall of the fixed frame, and an output end of the second airbag is connected to the air path system.

[0026] Beneficial effect: The second airbag is squeezed when the driving block moves, and the gas is sent into the air path system and connected to the first airbag, thereby realizing the inflation operation of the first airbag, simplifying the operation process, and improving the automation level of the entire device.

[0027] Furthermore, a threaded hole is formed on the first circular plate, and a hand-tightened bolt is fitted in the inner thread of the threaded hole.

[0028] Beneficial effect: The rotational cooperation between the second circular plate and the first circular plate enables the second circular plate to drive the U-shaped clamp and then drive the arthroscope to rotate for direction adjustment. When the arthroscope is rotated to a suitable surgical position, the arthroscope can be further fixed by tightening the hand bolt.

[0029] Furthermore, a shadowless lamp is fixedly connected to the base, and the controller is used to control the opening and closing of the shadowless lamp.

[0030] Beneficial effect: The shadowless lamp fixedly connected to the base provides sufficient light for surgery, allowing the doctor to clearly observe the surgical site.

[0031] Furthermore, Velcro straps are fixedly connected to the tops of the calf support plate and the thigh support plate.

[0032] Benefits: Velcro straps on the top of the calf and thigh support panels ensure the stability of the patient during surgery, and the Velcro straps can be flexibly adjusted according to the patient's body shape and surgical needs

[0033] Furthermore, the method for using the auxiliary support device for orthopedic arthroscopic surgery comprises the following steps:

[0034] Step 1: Place the device on the operating table, untie the Velcro straps, put the patient's thighs on the thigh support board, put the patient's calves on the calf support board, and then stick the Velcro straps to fix the patient's thighs and calves.

[0035] Step two, insert the arthroscope into the U-shaped clamp, start the controller, and control the drive member to start by the controller to adjust the angle between the patient's thigh and calf, adjust the angle between the patient's thigh and calf to a position convenient for surgical operation, then close the drive member by the controller, and then control the start of the first electric telescopic rod by the controller, rotate the rotating arm until the U-shaped clamp is above the patient's surgical site, control the extension and retraction of the second electric telescopic rod by the controller to adjust the arthroscope to a suitable height for the surgical position, then rotate the second circular plate until the arthroscope is directly above the patient's surgical position, tighten the hand-tightening bolt to fix the second circular plate, and then perform the surgical operation.

[0036] When the driving block slides on the slide groove in the fixed frame, the driving block will squeeze the second airbag, so that the gas in the second airbag enters the first airbag through the air path system. At this time, the first airbag will expand, allowing the first airbag to gradually contact and squeeze the arthroscope, thereby clamping the arthroscope and fixing the arthroscope inside the U-shaped clamp.

[0037] When a handheld arthroscope is needed, the connecting tube of the arthroscope can be placed in the U-shaped clamp. When the second airbag is compressed and the first airbag is expanded, the first airbag can gradually contact and squeeze the connecting tube of the arthroscope, thereby clamping the connecting tube of the arthroscope and fixing it inside the U-shaped clamp, and then the handheld arthroscope can be operated.

[0038] Step three, after the operation is completed, the controller controls the second electric telescopic rod output shaft to extend, and then controls the first electric telescopic rod output shaft to retract to move the arthroscopy away from the surgical position, untie the Velcro straps, move the patient's thigh and calf out of the device, turn off the controller power, and disinfect the outer surface of the device.

[0039] Beneficial effects: This method of use simplifies the surgical operation process and improves surgical efficiency and safety; at the same time, the flexibility and practicality of the device are fully demonstrated, which helps doctors perform more accurate and efficient surgical operations.

[0055] A clamping assembly for supporting the arthroscope is also provided on the top of the base 1 .

[0056] The clamping assembly includes an axle 15 and a first electric telescopic rod 14, the first electric telescopic rod 14 is fixedly connected to the top of the base 1 by screws, the controller is used to control the extension and retraction of the output shaft of the first electric telescopic rod 14, and the axle 15 is rotatably connected to the top of the base 1; a rack 16 is fixedly connected to the output shaft of the first electric telescopic rod 14 by screws; a gear 17 is coaxially integrally formed at one end of the axle 15 away from the base 1, and the gear 17 is meshed with the rack 16; a second electric telescopic rod 18 is coaxially fixedly connected to the top of the gear 17 by screws, and the controller is used to control the extension and retraction of the output shaft of the second electric telescopic rod 18; the output shaft of the second electric telescopic rod 18 is coaxially fixedly connected to a rotating arm 19 by screws, and a first circular plate 20 is fixedly welded to one end of the rotating arm 19 away from the second electric telescopic rod 18, a second circular plate 21 is rotatably connected to a side wall of the first circular plate 20 away from the rotating arm 19, and a U-shaped clamping claw 22 is fixedly welded to a side wall of the second circular plate 21 away from the first circular plate 20.

[0057] A first air bag is fixedly bonded to the inner wall of the U-shaped clamping jaw 22 , and an input end of the first air bag is connected to an air path system.

[0058] A second airbag is fixedly bonded to the side wall of the driving block 4 close to the driving member 10 , and a side wall of the second airbag away from the driving block 4 is fixedly bonded to the inner wall of the fixing frame 2 , and an output end of the second airbag is connected to the air path system.

[0059] A threaded hole 23 is formed on the first circular plate 20 , and a hand-tightened bolt 24 is fitted into the inner thread of the threaded hole 23 .

[0060] Velcro straps 25 are fixedly connected to the tops of the calf support plate 13 and the thigh support plate 12 .

[0061] The method for using the auxiliary support device for orthopedic arthroscopic surgery comprises the following steps:

[0062] Step 1, place the device on the operating table, untie the Velcro strap 25, put the patient's thigh on the thigh support board 12, put the patient's calf on the calf support board 13, and then stick the Velcro strap 25 to fix the patient's thigh and calf.

[0063] Step two, insert the arthroscope into the U-shaped clamp 22, start the controller, and control the driving member 10 to start through the controller to adjust the angle between the patient's thigh and calf, and adjust the angle between the patient's thigh and calf to a position convenient for surgical operation, then close the driving member 10 through the controller, and then control the start of the first electric telescopic rod 14 through the controller, rotate the rotating arm 19 until the U-shaped clamp 22 is above the patient's surgical site, control the extension and retraction of the second electric telescopic rod 18 through the controller to adjust the arthroscope to a suitable height for the surgical position, and then rotate the second circular plate 21 until the arthroscope is directly above the patient's surgical position, tighten the hand screw 24 to fix the second circular plate 21, and then perform the surgical operation.

[0064] When the driving block 4 slides on the slide groove in the fixed frame 2, the driving block 4 will squeeze the second airbag, so that the gas in the second airbag enters the first airbag through the air path system. At this time, the first airbag will expand, allowing the first airbag to gradually contact and squeeze the arthroscope, thereby clamping the arthroscope and fixing the arthroscope inside the U-shaped clamp 22.

[0065] When a handheld arthroscope is needed, the connecting tube of the arthroscope can be placed in the U-shaped clamp 22. When the second airbag is compressed and the first airbag is expanded, the first airbag can gradually contact and squeeze the connecting tube of the arthroscope, thereby clamping the connecting tube of the arthroscope and fixing it inside the U-shaped clamp 22, and then the handheld arthroscope can be operated.

[0066] Step three, after the operation is completed, the controller controls the output shaft of the second electric telescopic rod 18 to extend, and then controls the output shaft of the first electric telescopic rod 14 to retract to move the arthroscopy away from the surgical position, untie the Velcro strap 25, move the patient's thigh and calf out of the device, turn off the controller power, and disinfect the outer surface of the device.

[0067] The specific implementation process is as follows:

[0068] Place the auxiliary support device for orthopedic arthroscopic surgery on the operating table, clamp the arthroscope in the U-shaped clamp 22, and before performing orthopedic arthroscopic surgery, untie the Velcro straps 25 on the top of the calf support 13 and the thigh support 12, gently place the patient's thigh on the thigh support 12, and the calf on the calf support 13, adjust the tightness of the Velcro straps 25 according to the patient's body shape and surgical requirements, and ensure that the patient's legs are stably fixed on the thigh support 12 and the calf support 13.

[0069] The medical staff starts the reduction motor through the controller to start working. The output shaft of the reduction motor drives the screw 11 to rotate forward and reverse. Since the screw 11 is threadedly matched with the nut hole in the drive block 4, when the screw 11 rotates, it will push the drive block 4 to slide on the limit groove 3 in the fixed frame 2 along the length direction of the fixed frame 2.

[0070] like Figure 1 and Figure 2 As shown, when the driving block 4 slides, the sliding rods 5 on both sides of the driving block 4 are hinged with the connecting rod 6, and at the same time, since both ends of the rotating shaft 7 are rotatably connected to the fixed block 8, the bottom of the fixed block 8 is fixedly welded to the top of the base 1, and the rotating plate 9 and the rotating shaft 7 are coaxially integrated. The end of the connecting rod 6 away from the sliding rod 5 is hinged with the side wall of the rotating plate 9. At this time, the driving block 4 can drive the connecting rod 6 and then drive the rotating plate 9 to drive the rotating shaft 7 on the fixed block 8 with the rotating shaft 7 as the center. The rotation of the rotating plate 9 with the rotating shaft 7 as the center will change the angle between the connecting rod 6 and the rotating plate 9. At the same time, since the thigh support plate 12 is integrally formed on the side wall of the rotating plate 9, and the calf support plate 13 is integrally formed on the connecting rod 6 adjacent to it, the angle between the connecting rod 6 and the rotating plate 9 changes, which can drive the angle between the thigh support plate 12 and the calf support plate 13 to change; it can realize the change of the angle of the patient's legs, and realize the function of automatically adjusting the patient's leg support.

[0071] Medical staff can use the controller to accurately control the rotation of the output shaft of the reduction motor, so as to accurately adjust the angle between the thigh support plate 12 and the calf support plate 13 to the optimal surgical position. During the operation, medical staff can also fine-tune the position of the patient's legs through the controller according to the progress of the operation and the specific conditions of the patient, ensuring that the surgical site is always in the best observation and treatment position; when the patient's legs are adjusted to the optimal surgical position, the medical staff can turn off the reduction motor through the controller to keep the drive block 4 and the connecting rod 6 in the current position, and the thigh support plate 12 and the calf support plate 13 also remain in the current position. At this time, the patient's legs are stably supported on the auxiliary support device, providing a good operating platform for the operation.

[0072] Medical staff can control the start of the first electric telescopic rod 14 through the controller. The extension and retraction of the output shaft of the first electric telescopic rod 14 will drive the rack 16 to move. Since the rack 16 is meshed with the gear 17, the rack 16 will drive the gear 17 to rotate as the output shaft of the first electric telescopic rod 14 is extended and retracted. Since the gear 17 and the second electric telescopic rod 18 are fixedly connected by screws, the rotating arm 19 and the second electric telescopic rod 18 are coaxially fixedly connected by screws. At this time, the rotation of the gear 17 will drive the second electric telescopic rod 18 to rotate and then drive the rotating arm 19 to rotate, thereby bringing the U-shaped clamp 22 and the arthroscope to the top of the surgical site. Then the medical staff controls the extension and retraction of the second electric telescopic rod 18 through the controller. The second electric telescopic rod 18 can drive the rotating arm 19 to move up and down, thereby adjusting the height of the arthroscope to ensure that the lens is at the best observation angle. At the same time, the design of the first electric telescopic rod 14 and the second electric telescopic rod 18 can reduce the damage to the patient during surgery caused by the inertia of the rotation of the motor output shaft due to the traditional motor transmission method, thereby improving the effect of the surgery.

[0073] like Figure 4 As shown, since the first circular plate 20 is fixedly welded to the end of the rotating arm 19 away from the second electric telescopic rod 18, the second circular plate 21 is rotatably connected to a side wall of the first circular plate 20 away from the rotating arm 19, and the U-shaped clamp 22 is fixedly welded to a side wall of the second circular plate 21 away from the first circular plate 20, the medical staff rotates the arthroscope with the rotating arm 19 as the center so that the second circular plate 21 can rotate on the first circular plate 20. After the medical staff rotates the arthroscope to a suitable position, the arthroscope lens is extended and inserted into the patient's surgical position. At this time, the medical staff twists the hand-tightening bolt 24 until it cannot be twisted; at this time, the arthroscope can be firmly fixed on the U-shaped clamp 22, and the medical staff can start arthroscopic surgery.

[0074] When the driving block 4 slides on the slide groove in the fixed frame 2, the driving block 4 will squeeze the second airbag, so that the gas in the second airbag enters the first airbag through the air path system. At this time, the first airbag will expand, allowing the first airbag to gradually contact and squeeze the arthroscope, thereby clamping the arthroscope and fixing the arthroscope inside the U-shaped clamp 22, further increasing the clamping effect of the U-shaped clamp 22 on the arthroscope.

[0075] When medical staff need to hold the arthroscope, the connecting tube of the arthroscope can be placed in the U-shaped clamp 22. When the second airbag is compressed and the first airbag is expanded, the first airbag can gradually contact and squeeze the connecting tube of the arthroscope, thereby clamping the connecting tube of the arthroscope and fixing it inside the U-shaped clamp 22. The medical staff can then perform handheld arthroscope operations. By fixing the connecting tube of the arthroscope when the medical staff holds the arthroscope, the connecting tube of the arthroscope can be prevented from shaking and falling off during surgery, thereby increasing the safety and efficiency of the surgery.

[0076] After the operation is completed, the medical staff controls the output shaft of the second electric telescopic rod 18 to extend through the controller, and then controls the output shaft of the first electric telescopic rod 14 to retract to move the arthroscopy away from the surgical position, unfastens the Velcro strap 25, moves the patient's thigh and calf out of the device, turns off the power of the controller, and disinfects the outer surface of the device.

[0077] The auxiliary support device for orthopedic arthroscopic surgery of the present invention reduces the number of times medical staff manually adjust the position of the arthroscope, and also reduces the risks that may be caused by improper operation, further improving the safety and reliability of the surgery.

[0078] Embodiment 2:

[0079] As attached Figure 1-Figure 3 As shown, the difference from Example 1 is that a shadowless lamp is fixedly connected to the base 1 by screws, and the controller is used to control the opening and closing of the shadowless lamp.

[0080] The specific implementation process is as follows: the shadowless lamp fixedly connected to the base 1 by screws provides sufficient light for the operation, so that the doctor can clearly observe the surgical site.

[0081] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
