Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary products, in particular to a foot switch auxiliary device for orthopedic surgery. Background Art

[0002] Minimally invasive orthopedic surgery is the current development trend, and endoscopic surgery has become the norm. Such surgeries require the use of minimally invasive surgery operating systems such as radiofrequency plasma ablation systems, power drilling systems, and ultrasonic bone knife systems. Most of the above equipment requires the use of foot switches. Take the radiofrequency plasma ablation system foot switch as an example. Figure 1 As shown, the foot switch includes a base 17, two sub-switches 18 arranged on the base 17, and a transmission line 19 for transmitting signals, wherein the two sub-switches 18 correspond to different powers and functions respectively, and the doctor performs the operation by means of the foot sub-switches 18.

[0003] When the foot switch needs to be operated for a long time, it has many shortcomings. First, the stability of the foot switch is poor. Since the floor is usually a tile floor, especially when there is water on the floor, the base is prone to sliding when using the foot switch, resulting in a change in position. The operator is prone to stepping on it by mistake. When stepping on it by mistake, it will cause damage to the patient's tissue and may even lead to medical accidents. Therefore, the operator needs to lower his head from time to time to determine the position of the foot switch, which affects the operation. Second, when using the foot switch, the sub-switch is often touched by the toes. Therefore, after placing the foot switch, the sub-switch is closer to the operator than the operating table. At this time, there will be a certain distance between the operator and the operating table. The operator needs to lean to one side of the operating table during operation. When the operation time is too long, the human body fatigue increases, and back pain is more common. The operator in a fatigued state cannot guarantee the high-quality completion of the operation.

[0004] In view of the many shortcomings of the above foot switches in actual usage scenarios, a foot switch auxiliary device was developed that can effectively fix the foot switch, easily distinguish the left and right switches, keep the body inclination at a minimum during use, and is not likely to cause operator fatigue. Summary of the invention

DETAILED DESCRIPTION

[0027] The present invention is described below in conjunction with the accompanying drawings. The specific implementation methods described herein are only used to illustrate and explain the present invention and are not used to limit the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solution of the present invention by ordinary technicians in this field should fall within the protection scope of the present invention.

[0028] like Figures 2 to 6 As shown, the foot switch auxiliary device for orthopedic surgery in this embodiment includes a foot pedal 1, a baffle, a foot column 2 and an elastic connection component.

[0029] Among them, the foot pedal 1 and the baffle are both square plates, and are made of transparent materials. A plurality of baffles are arranged below the foot pedal 1, and the plurality of baffles enclose a placement area for placing the foot switch. In this embodiment, there are five baffles, namely the first baffle 4, the second baffle 5, the third baffle 6, the fourth baffle 7 and the fifth baffle 8, wherein the first baffle 4 and the second baffle 5 are respectively arranged along the two short sides of the foot pedal 1, the third baffle 6 is arranged along one of the long sides of the foot pedal 1, and the two ends of the third baffle 6 are respectively connected vertically to the ends of the first baffle 4 and the second baffle 5. The fourth baffle 7 and the fifth baffle 8 are vertically staggered in the middle of the lower surface of the foot pedal 1, and one end of the fourth baffle 7 is connected to the board surface of the third baffle 6. The two ends of the fifth baffle 8 are respectively connected to the board surfaces of the first baffle 4 and the second baffle 5. The first baffle plate 4, the third baffle plate 6, the fourth baffle plate 7 and the fifth baffle plate 8 together form a first placement area, and the second baffle plate 5, the third baffle plate 6, the fourth baffle plate 7 and the fifth baffle plate 8 together form a second placement area. The board surface of the foot pedal 1 located above the first placement area is provided with two through holes 3, and the board surface of the foot pedal 1 located above the second placement area is provided with three through holes 3. The through holes 3 on the foot pedal 1 are arranged side by side and spaced along the length direction of the foot pedal 1. The first placement area is used to place a foot switch with two sub-switches, and the second placement area is used to place a foot switch with three sub-switches, so that the device has a high applicability. These five baffles can not only play the role of enclosure, but also play the role of support.

[0030] After placing the foot switch in the placement area, each through hole 3 can correspond to a sub-switch of the foot switch, and each through hole 3 is arranged close to the edge of the foot pedal 1 and close to the third baffle 6. Therefore, when placing the foot switch in the placement area, compared with the existing way of placing the foot switch, it is opposite. After the third baffle 6 is attached to the edge of the operating bed, the sub-switch of the foot switch is closer to the operating bed.

[0031] Each through hole 3 is provided with a pedal column 2, which can move up and down in the through hole 3. The side wall of the pedal column 2 in the placement area is elastically connected to the lower surface of the pedal board 1 through at least one elastic connection component. The operator moves the pedal column downward by stepping on the pedal column 2, and the lower end of the pedal column 2 presses down the sub-switch corresponding to its position, thereby achieving the purpose of operating the sub-switch. At this time, the elastic connection component generates elastic force. After the pedal column 2 is released, the elastic connection component releases the elastic force and resets the pedal column 2. The lower end surface of the pedal column 2 is protruding downward and is provided with a fixing nail 16. The function of the fixing nail 16 is to make the squeezing between the pedal column 2 and the sub-switch more concentrated, that is, to adopt a point contact method, while reducing the friction between the pedal column 2 and the sub-switch.

[0032] The elastic connection assembly of the present embodiment includes a fixing belt 12 and two springs 13, wherein the fixing belt 12 is fixed on the side wall of the pedal column 2 located in the placement area, one end of the two springs 13 is connected to the fixing belt 12, and the other end is connected to the lower board surface of the pedal 1. When the pedal column 2 is stepped on, the two springs 13 will stretch and generate elastic force. After the pedal column 2 is released, the two springs 13 release the elastic force and drive the pedal column 2 to reset. In addition, the fixing belt 12 of the present embodiment is annular, which is sleeved on the pedal column 2, and the middle part is disconnected. The disconnection part is provided with an elastic adjustment structure. The function of the elastic adjustment structure is to adjust the elasticity of the fixing belt 12. After the fixing belt 12 is loosened, the length of the pedal column 2 located in the placement area can be adjusted as needed. After the adjustment, the fixing belt 12 is tightened again to fix the position of the pedal column 2. Specifically in this embodiment, the tension adjustment structure includes an adjusting bolt 14 and two fixing blocks 15. The two fixing blocks 15 are relatively arranged on both sides of the broken end of the fixing belt 12. The surfaces of the two fixing blocks 15 are provided with screw holes for inserting the adjusting bolts 14. The end of the adjusting bolt 14 is screwed from the screw hole of one of the fixing blocks 15 into the screw hole of the other fixing block 15. Tightening the adjusting bolt 14 can reduce the distance between the broken ends of the fixing belt 12, so that the fixing belt 12 is fastened to the foot column 2. Loosening the adjusting bolt 14 increases the distance between the broken ends of the fixing belt 12, so that the foot column 2 can move in the middle of the fixing belt 12.

[0033] In this embodiment, the outer surface of the first baffle plate 4 is provided with a handle 9, and the outer surface of the second baffle plate 5 is provided with a plurality of universal wheels 10. The user can hold the handle 9 and cooperate with the universal wheels 10 to push the device to move, which has the advantage of convenient transportation. The board surface of the fifth baffle plate 8 is provided with a wire hole 11 for passing the foot switch transmission line, which is convenient for passing the transmission line 19. In another embodiment, the board surfaces of the first baffle plate 4, the second baffle plate 5, the third baffle plate 6, the fourth baffle plate 7 and the fifth baffle plate 8 are provided with ventilation holes. After the device is cleaned and disinfected, the ventilation holes facilitate the drying of the device.

[0034] When the present invention is used, the foot switch is placed in the placement area of ​​the corresponding hole position according to the number of sub-switches, and the position of the sub-switch is made corresponding to the position of the through hole 3. Then the operator stands on the foot pedal 1, and the operator can operate the sub-switch by stepping on the foot pedal column 2. Under the action of the operator's gravity, the entire device is not easy to move. At the same time, under the enclosure of multiple baffles, the foot pedal will not move, thereby playing an effective fixing role for the foot switch. The foot switch does not move, making it difficult for the operator to step on it by mistake. At the same time, the foot pedal column 2 can facilitate the operator to distinguish between different switches on the left and right. Since the through hole 3 is close to the edge of the foot pedal 1, the way of placing the foot switch is opposite to the existing way. At this time, the position of the sub-switch is closer to the operating bed. At this time, the third baffle 6 can be close to the edge of the operating bed, so that when the operator operates the foot switch, the distance between the operator and the operating bed is smaller, and during use, the body inclination is smaller, which is not easy to cause the operator to experience surgical fatigue.
