Description

Lifting type pedal for operation

Technical Field

The application relates to the field of medical equipment, in particular to a lifting type pedal for operation.

Background

At present, the surgery of the department of the hospital needs a main knife, one assistant, two assistants and even three assistants; each operator has different height, the height of the operating table is the optimum height matched with the main knife, and other operators determine whether to need the pedal plate according to the position of the station in the operation and the height of the operator. At present, a plurality of hospital operating rooms use pedals with fixed heights of four foot rests of stainless steel plates, and many times, assistants can only visit nurses to find pedals with other heights on the basis of aseptic principle because the heights of the pedals are not suitable; however, the high pedal is often too high, the low pedal is too low, the operation process is influenced by moving and replacing the pedals, the operation can only be carried out when the height is not suitable, and the operator is also very difficult to use, so that the operation is influenced. The circulating nurse may need to go to a nearby operating room to find the pedal with the proper height, the circulating nurse is often busy when a major operation is performed, and even if the pedal is arranged in the operating room, the pedal cannot be replaced for the operator in time.

However, the conventional surgical foot pedal has the following drawbacks: 1. many hospitals use surgical footrests of fixed height; however, due to the different heights of the medical staff, the foot pedal with the proper height for the operation is usually required to be searched before or during the operation so as to meet the requirement that the operator completes the operation at the optimal height; 2. searching for a surgical foot pedal with a proper height inevitably wastes time and human resources, so that a hospital which is in shortage of hands cannot work, and the situation that the surgical foot pedal with a proper height is used for surgery occurs, so that the surgical operation is influenced.

Therefore, it is an urgent need for those skilled in the art to improve the conventional surgical foot pedal to overcome the above-mentioned shortcomings.

Disclosure of Invention

An object of this application is to provide a rationally distributed, convenient to use, but height-adjusting reduces the influence to the operation, and reduces the over-and-under type operation running-board to manpower resources uses.

In order to achieve the above purposes, the technical scheme adopted by the application is as follows: a lifting type pedal for operation comprises a base, a pedal, a lifting mechanism and a controller; the lower end of the lifting mechanism is arranged at the upper end of the base, and the upper end of the lifting mechanism is arranged at the lower end of the pedal; the controller is arranged on the pedal and used for controlling the lifting mechanism to lift.

Preferably, the controller comprises a control part, a return spring and two control buttons; the control part comprises a first cross rod, a second cross rod and a connecting rod, and the first cross rod, the connecting rod and the second cross rod are sequentially connected to form an I-shaped structure; the connecting rod is rotatably arranged on the pedal, the second cross rod is positioned on the outer side of the pedal, and the first cross rod is positioned below the pedal; the return spring is arranged between the pedal and the first cross rod and is used for forcing the first cross rod and the second cross rod to rotate to a horizontal state along with the connecting rod; the two control buttons are arranged on the lower surface of the pedal, are respectively aligned with two ends of the first cross rod, and are respectively used for controlling the lifting mechanism to ascend and descend; when the second cross rod is rotated, the first cross rod synchronously rotates, and one end of the first cross rod is pressed to correspond to the control button. The advantages are that: when the height of the lifting type surgical foot pedal needs to be adjusted, the first cross rod synchronously rotates and presses the corresponding control button only by rotating the second cross rod, so that the lifting mechanism ascends or descends, and the height of the lifting type surgical foot pedal is adjusted. By arranging the return spring between the first cross rod and the pedal, the return spring forces the first cross rod and the second cross rod to rotate to a horizontal state along with the connecting rod after the second cross rod is rotated; this prevents the control unit from being erroneously touched by the control button due to the swing of the lifting type operation foot pedal, and facilitates the next use of the control unit.

Preferably, a protrusion is arranged on a portion of the first cross bar corresponding to the control button. The advantages are that: the protrusion can improve the contact stability between the end of the first cross rod and the control button, and ensure the reliability of opening the control button through the first cross rod.

Preferably, both ends of the second cross rod are provided with pedal parts. The advantages are that: under the effect of pedal pad, not only can confirm with the position of foot pedal second horizontal pole, can also increase the area with foot contact to be difficult to appear stepping on empty phenomenon.

Preferably, the lifting type foot pedal for operation further comprises a cover plate, wherein the cover plate is connected to the pedal in a sliding manner; when the cover plate slides to the upper part of the second cross rod, the cover plate can cover the second cross rod. The advantages are that: the cover plate slides to the direction deviating from the pedal, and the cover plate covers the second cross rod, so that the second cross rod can be prevented from being touched by mistake when the lifting type pedal for operation is used, and the area of a platform for standing is enlarged; when the height of the lifting type foot pedal for operation needs to be adjusted, the cover plate slides towards the direction of the foot pedal until the second cross rod is completely leaked out, and then the height of the lifting type foot pedal for operation is adjusted through the second cross rod. When the second cross rod is provided with the pedal part, the cover plate can cover the pedal part at the same time.

Preferably, the pedal and/or the cover plate are/is provided with anti-skid grains. The advantages are that: when the anti-skid lines are arranged on the pedal, the friction coefficient of the pedal is increased; this prevents a slip phenomenon from occurring between the foot and the step when the elevating type operation foot pedal is used. When the anti-skid grains are arranged on the cover plate, the friction coefficient of the cover plate is increased; this prevents the sliding between the legs and the cover plate when the lifting type operation foot pedal is used, and prevents the legs and the cover plate from sliding when the cover plate is slid by the legs.

Preferably, the lifting mechanism comprises a driving part and a scissor rod assembly, the scissor rod assembly and the driving part are arranged between the pedal and the base, and the driving part is used for driving the scissor rod assembly to extend and retract; the shearing fork rod assemblies are at least two groups, and reinforcing members are connected between every two adjacent shearing fork rod assemblies. The advantages are that: the telescopic motion of the scissor rod assembly can be controlled by controlling the reciprocating motion of the driving piece (such as an electric hydraulic cylinder, an electric jack and the like); this allows the lifting mechanism to be raised or lowered. The stability of the lifting type foot pedal for operation is improved by arranging at least two groups of the scissors assemblies; this further improves the stability of the liftable foot rest for surgery by connecting the reinforcement member between the adjacent scissor lever assemblies. This reduces the requirements on material strength and reduces costs.

Preferably, one upper end of the scissor rod assembly is hinged to the lower end of the pedal, and the other upper end of the scissor rod assembly is connected to the lower surface of the pedal in a rolling manner through a first roller; one lower end of the scissor rod assembly is hinged to the upper end of the base, and the other lower end of the scissor rod assembly is connected to the upper surface of the base in a rolling mode through a second roller. The advantages are that: the scissor rod assembly and the pedal are hinged, and the scissor rod assembly and the base are hinged; this both secures the scissor assembly between the base and the pedal and does not affect the telescoping of the scissor assembly. When the scissor rod assembly stretches, the first roller rolls on the pedal, and the second roller rolls on the base; the first roller and the second roller reduce the friction between the scissor rod assembly and the pedal and between the scissor rod assembly and the base, so that the resistance of the scissor rod assembly during stretching is reduced.

Preferably, one end of the scissor rod assembly, on which the first roller is arranged, is horizontally slidably connected to the pedal, and one end of the scissor rod assembly, on which the second roller is arranged, is horizontally slidably connected to the base. The advantages are that: one end of the scissor rod assembly, which is provided with the first roller, is connected to the pedal in a sliding manner, and one end of the scissor rod assembly, which is provided with the second roller, is connected to the base in a sliding manner; the upper end of the scissor rod assembly is completely connected with the pedal, and the lower end of the scissor rod assembly is completely connected with the base; this allows for separation between the scissor assembly and the foot plate and/or between the scissor assembly and the base when the lift surgical foot pedal is being handled or used.

Preferably, the lifting type foot pedal for operation further comprises a handle, and the handle is arranged on the pedal. The advantages are that: the number of the handles is preferably two, and the two handles are symmetrically arranged on the side surface of the tower plate, so that the lifting type operation pedal is convenient to transfer, and the handle is prevented from being polluted by soles of medical staff.

Compared with the prior art, the beneficial effect of this application lies in: (1) when in use, the lifting type foot pedal for operation is moved to a proper position beside an operation table; then the controller controls the lifting mechanism to ascend or descend so as to enable the lifting type operation foot pedal to reach a certain height; and finally, standing on the pedal to judge whether the height of the lifting type operation foot pedal is proper or not, so that the height of the lifting type operation foot pedal is further adjusted (if the height of the lifting type operation foot pedal is lower, the lifting mechanism is controlled to ascend through the controller, and if the height of the lifting type operation foot pedal is higher, the lifting mechanism is controlled to descend through the controller) until the height suitable for an operator is found. Compared with the operation pedal with fixed height, the lifting type operation pedal is reasonable in layout, convenient to use and adjustable in height, so that the influence on operation can be reduced, and the use of manpower resources can be reduced.

(2) When the controller comprises the control part, the return spring and the two control buttons, the height of the lifting type operation pedal can be adjusted by stepping on the second cross rod by feet or rotating the second cross rod by hands, and the operation is simple; meanwhile, in the operation process, the height of the lifting type operation foot pedal can be adjusted by only stepping on the second cross rod by feet, so that an operator can perform the operation at a proper height all the time, and the sterile state of the hands of the operator or a nurse is ensured.

The terms "comprises," "comprising," and "having," and any variations thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Referring to fig. 1 to 5, an embodiment of the present application provides an elevating type surgical footrest, including a base 1, a pedal 2, an elevating mechanism 3, and a controller 4; the lower end of the lifting mechanism 3 is arranged at the upper end of the base 1, and the upper end of the lifting mechanism 3 is arranged at the lower end of the pedal 2; the controller 4 is disposed on the pedal 2, and the controller 4 is configured to control the lifting mechanism 3 to lift. When in use, the lifting type foot pedal for operation is firstly moved to a proper position beside an operation table; then the controller 4 controls the lifting mechanism 3 to ascend or descend, so that the lifting type operation foot pedal reaches a certain height; and finally, standing on the pedal 2 to judge whether the height of the lifting type operation foot pedal is proper or not, so that the height of the lifting type operation foot pedal is further adjusted (if the height of the lifting type operation foot pedal is lower, the lifting mechanism 3 is controlled to ascend through the controller 4, and if the height of the lifting type operation foot pedal is higher, the lifting mechanism 3 is controlled to descend through the controller 4) until the height suitable for the operator is found. Compared with the operation pedal with fixed height, the lifting type operation pedal is reasonable in layout, convenient to use and adjustable in height, so that the influence on operation can be reduced, and the use of manpower resources can be reduced.

Referring to fig. 1-2 and 4-5, in some embodiments of the present application, the controller 4 includes a control portion 41, a return spring 42, and two control buttons 43; the control part 41 comprises a first cross bar 411, a second cross bar 413 and a connecting rod 412, wherein the first cross bar 411, the connecting rod 412 and the second cross bar 413 are sequentially connected to form an I-shaped structure; the connecting rod 412 is rotatably arranged on the pedal 2, the second cross rod 413 is positioned at the outer side of the pedal 2, and the first cross rod 411 is positioned below the pedal 2; the return spring 42 is arranged between the pedal 2 and the first cross bar 411 and is used for forcing the second cross bar 413 and the first cross bar 411 to rotate to a horizontal state along with the connecting rod 412; two control buttons 43 are arranged on the lower surface of the pedal 2, the two control buttons 43 are respectively aligned with two ends of the first cross bar 411, and the two control buttons 43 are respectively used for controlling the lifting mechanism 3 to ascend and descend; when the second cross bar 413 is rotated, the first cross bar 411 is synchronously rotated, and one end of the first cross bar 411 is pressed against the corresponding control button 43. When the height of the lifting type foot pedal for operation needs to be adjusted, the first cross bar 411 synchronously rotates and presses the corresponding control button 43 only by rotating the second cross bar 413, so that the lifting mechanism 3 ascends or descends, and the height of the lifting type foot pedal for operation is adjusted. By arranging the return spring 42 between the first cross bar 411 and the pedal 2, the return spring 42 forces the first cross bar 411 and the second cross bar 413 to rotate to a horizontal state along with the connecting rod 412 after the second cross bar 413 is rotated; this prevents the control unit 41 from erroneously touching the control button 43 due to the swing of the lifting/lowering type operation foot pedal, and facilitates the next use of the control unit 41. It should be noted that the control button 43 itself and the way in which the control button 43 controls the lifting mechanism 3 to lift both belong to the prior art, and are not described in detail herein. In addition, the rotatable mounting manner of the connecting rod 412 is the prior art, and for example, the connecting rod can be mounted through a bearing and a bearing seat, which are not described in detail herein.

Referring to fig. 4-5, in some embodiments of the present application, a protrusion 4111 is disposed on the first cross bar 411 at a position corresponding to the control button 43. The protrusion 4111 may improve the stability of the contact between the end of the first cross bar 411 and the control button 43, and ensure the reliability of opening the control button 43 through the first cross bar 411.

Referring to fig. 4-5, in some embodiments of the present application, the second cross bar 413 is provided with footrests 4131 at both ends. Under the action of the pedal pad 4131, not only the position where the second cross bar 413 is stepped on by the foot can be determined, but also the area contacting with the foot can be increased, so that the stepping-on phenomenon is not easy to occur.

Referring to fig. 1-2, in some embodiments of the present application, the lifting surgical footrest further includes a cover plate 5, the cover plate 5 being slidably connected to the footrest 2; when the cover 5 slides over the second rail 413, the cover 5 covers the second rail 413. The cover plate 5 slides towards the direction deviating from the pedal 2, and the cover plate 5 covers the second cross rod 413, so that the second cross rod 413 can be prevented from being touched by mistake when the lifting type pedal for operation is used, and the area of a platform for standing is enlarged; when the height of the lifting type operation foot pedal needs to be adjusted, the cover plate 5 slides towards the direction of the pedal 2 until the second cross rod 413 is completely leaked out, and then the height of the lifting type operation foot pedal is adjusted through the second cross rod 413. When the second cross bar 413 is provided with the foothold 4131, the cover 5 may cover the foothold 4131 at the same time. It should be noted that the sliding installation manner between the cover plate and the tower plate is the prior art, and detailed description is omitted here.

Referring to fig. 1-2, in some embodiments of the present application, the deck 2 and/or the deck 5 are provided with non-slip threads 21. When the anti-skid grains 21 are arranged on the pedal 2, the friction coefficient of the pedal 2 is increased; this prevents the sliding phenomenon between the foot and the step 2 when the lifting type operation foot pedal is used. When the cover plate 5 is provided with the anti-skid grains 21, the friction coefficient of the cover plate 5 is increased; this prevents the sliding between the legs and the cover plate 5 when the lifting type operation foot pedal is used, and prevents the sliding between the legs and the cover plate 5 when the cover plate 5 is slid by the legs.

Referring to fig. 1-3, in some embodiments of the present application, the lifting mechanism 3 includes a driving member 31 and a scissor-rod assembly 32, the scissor-rod assembly 32 and the driving member 31 are disposed between the pedal 2 and the base 1, and the driving member 31 is used for driving the scissor-rod assembly 32 to extend and retract; at least two groups of scissors rod assemblies 32 are arranged, and a reinforcing member 7 is connected between the adjacent scissors rod assemblies 32. The extension and retraction of the scissor rod assembly 32 can be controlled by controlling the reciprocating motion of the driving piece 31; this allows the lifting mechanism 3 to be raised or lowered. The stability of the lifting type foot pedal for operation can be improved by arranging at least two groups of scissor assemblies; this further improves the stability of the liftable surgical foot pedal by connecting the reinforcement members 7 between adjacent scissor bar assemblies 32. This reduces the requirements on material strength and reduces costs. It should be noted that the scissor lever assembly 32 itself, the driving member 31 itself (such as an electric hydraulic cylinder, an electric jack, etc.), and the manner in which the driving member 31 controls the scissor lever assembly 32 to extend and retract all belong to the prior art, and detailed descriptions thereof are omitted here.

Referring to fig. 1-3, in some embodiments of the present application, one upper end of the scissors bar assembly 32 is hinged to the lower end of the pedal 2, and the other upper end of the scissors bar assembly 32 is connected to the lower surface of the pedal 2 by a first roller in a rolling manner; one lower end of the scissors rod assembly 32 is hinged to the upper end of the base 1, and the other lower end of the scissors rod assembly 32 is connected to the upper surface of the base 1 in a rolling manner through a second roller. The scissor rod assembly 32 is hinged with the pedal 2, and the scissor rod assembly 32 is hinged with the base 1; this both secures the scissor lever assembly 32 between the base 1 and the pedal 2 and does not affect the telescoping of the scissor lever assembly 32. When the scissor rod assembly 32 is stretched, the first roller rolls on the pedal 2, and the second roller rolls on the base 1; the first and second rollers reduce the friction between the scissor lever assembly 32 and the pedal 2 and between the scissor lever assembly 32 and the base 1, thereby reducing the resistance of the scissor lever assembly 32 during extension and retraction.

Referring to fig. 1-3, in some embodiments of the present application, the end of the scissor lever assembly 32 having the first roller is horizontally slidably connected to the pedal 2, and the end of the scissor lever assembly 32 having the second roller is horizontally slidably connected to the base 1. One end of the scissor rod assembly 32, which is provided with the first roller, is connected to the pedal 2 in a sliding manner, and one end of the scissor rod assembly 32, which is provided with the second roller, is connected to the base 1 in a sliding manner; the upper end of the scissor rod assembly 32 is completely connected with the pedal 2, and the lower end of the scissor rod assembly 32 is completely connected with the base 1; this allows for separation between the scissor assembly 32 and the step 2 and/or the scissor assembly 32 and the base 1 when the lift foot pedal is being carried or used. It should be noted that, the sliding connection modes between the scissor lever assembly 32 and the base 1 and between the scissor lever assembly 32 and the pedal 2 are all in the prior art, and are not described in detail herein.

Referring to fig. 1-2, in some embodiments of the present application, the lift surgical footrest further includes a handle 6, and the handle 6 is disposed on the footrest 2. The handles 6 are preferably two, and the two handles 6 are symmetrically arranged on the side surface of the pedal 2, which not only facilitates the transfer of the lifting type operation pedal, but also avoids the handle 6 from being polluted by soles of medical staff.

To sum up, this over-and-under type is running-board for operation rationally distributed, convenient to use, but height-adjusting reduces the influence to the operation, and reduces the use to manpower resources.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and such changes and modifications are intended to be within the scope of the application as claimed.
