Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a support frame and an endoscope host. Background Art

[0002] An endoscope host is a medical instrument used in the field of clinical medicine. It can connect various types of endoscopes and perform imaging on a monitor. At present, in order to meet the needs of doctors, the existing endoscope host can be rotated so that the endoscope host can be placed horizontally or vertically to meet the imaging needs in different scenarios.

[0003] In the process of rotating the existing endoscope mainframe, the operator needs to use one hand to rotate the endoscope mainframe and the other hand to rotate the support frame. Only with the cooperation of the two hands can the endoscope mainframe be placed horizontally or vertically. During the operation, the operator usually needs to hold the endoscope handle with the other hand, and it is difficult to free up an extra hand to rotate the support frame.

[0004] Therefore, providing a support frame and an endoscope host that can be operated with one hand is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] The invention discloses a support frame and an endoscope mainframe, so as to solve the technical problem that the endoscope mainframe in the related art cannot switch the placement state by one-hand operation.

[0006] In order to solve the above problems, the present invention adopts the following technical solutions:

[0007] In a first aspect, a support frame is disclosed, including a support assembly, wherein the support assembly includes a rotating member and a supporting member; the rotating member is rotatably arranged on a housing and can rotate around its own axis; the supporting member is connected to the rotating member;

[0008] The support assembly is configured so that the friction force between the rotating member and the housing when the rotating member rotates is smaller than the torsion force applied to the rotating member by the support member under the action of gravity.

[0009] In some solutions, the support member can rotate around the rotating member; an eccentric wheel is provided at the connection between the support member and the rotating member;

[0010] When the support member rotates to the first position, the distal end of the eccentric wheel abuts against the housing;

[0011] When the supporting member rotates to the second position, the distal end of the eccentric wheel abuts against the rotating member.

[0012] In some embodiments, the rotating member has a mounting hole, and one end of the supporting member extends into the mounting hole and is rotatably connected to the mounting hole;

[0013] The mounting hole has a limiting portion, and when the support component rotates to the second position, the eccentric distal end abuts against the limiting portion.

[0014] In some solutions, a locking assembly is also included, and the locking assembly includes a plurality of limit blocks;

[0015] A plurality of limit blocks are arranged along the circumference of the rotating member and are respectively slidably connected to the housing; the limit blocks can move toward or away from the axis of the rotating member;

[0016] The outer peripheral wall of the rotating member is provided with one of a protrusion and a slot, and the limit block is provided with the other one near the end surface of the rotating member; the protrusion can be inserted into the slot to limit the rotation of the rotating member.

[0017] In some embodiments, the protrusion has two inclined guide surfaces;

[0018] When the protrusion is arranged on the rotating member, the two guide surfaces are moved closer to the inner side from the limit block by the rotating member;

[0019] When the protrusion is arranged on the limit block, the two guide surfaces are moved closer to the inner side of the rotating member from the limit block.

[0020] In some embodiments, the locking assembly further includes a resilient member; when the protrusion is aligned with the slot, the resilient member drives the limit block to move toward the rotating member, so that the protrusion is locked into the slot.

[0021] In some embodiments, the housing is used to mount an endoscope host;

[0022] Alternatively, the housing is part of the endoscope host.

[0023] In some aspects, the housing has a first placement portion and a second placement portion;

[0024] When the shell is placed vertically, the first placement portion supports the shell; when the shell is placed horizontally, the second placement portion supports the shell;

[0025] The distance between the axis of the rotating member and the first placement portion is equal to the distance between the axis of the rotating member and the second placement portion.

[0026] In some aspects, the support member has a support portion;

[0027] When the housing is placed vertically, the support portion is parallel to the first placement portion;

[0028] When the housing is placed horizontally, the supporting portion is parallel to the second placement portion.

[0029] In a second aspect, an endoscope mainframe is disclosed, comprising the support frame in the first aspect.

[0030] The technical solution adopted by the present invention can achieve the following beneficial effects:

[0031] When the support frame of the present application is in use, the support member supports the shell, so that the endoscope host can be placed at an angle. When the endoscope host is switched from horizontal placement to vertical placement, or from vertical placement to horizontal placement, the operator holds the endoscope host in one hand and turns it 90 degrees. Under the action of gravity, the support member will apply torque to the rotating member, and the torque is greater than the friction force when the rotating member and the shell rotate, so that the support assembly can automatically rotate without setting an additional power source to meet the support requirements when the endoscope host is placed horizontally or vertically.

[0055] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0056] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0057] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0058] The applicant found that during the use, the existing endoscope host 300 needs the operator to rotate the endoscope host 300 with one hand and the support frame 100 with the other hand. Only with the cooperation of the two hands can the endoscope host 300 be placed horizontally or vertically. During the operation, the operator usually needs to hold the endoscope handle with the other hand, and it is difficult to free up an extra hand to rotate the support frame 100.

[0059] The following is combined with Figures 1 to 18 , a support frame 100 and an endoscope host 300 provided in the present application are described in detail through specific embodiments and their application scenarios.

[0060] Some embodiments of the present application provide a support frame 100, please refer to Figure 1-Figure 4 and Fig. 9 , including a supporting assembly and a locking assembly 130 .

[0061] like Figure 1-Figure 4 As shown, the support assembly includes a rotating member 110 and a supporting member 120. The rotating member 110 is rotatably disposed on the housing 200 and can rotate around its own axis, and the supporting member 120 is connected to the rotating member 110. The support assembly is configured such that the friction force when the rotating member 110 rotates with the housing 200 is smaller than the torsion force applied to the rotating member 110 by the supporting member 120 under the action of gravity.

[0062] When the support frame 100 is in use, the support member 120 supports the housing 200, so that the endoscope host 300 can be placed at an angle. When the endoscope host 300 is switched from horizontal placement to vertical placement, or from vertical placement to horizontal placement, the operator holds the endoscope host 300 with one hand and turns 90 degrees. Under the action of gravity, the support member 120 will apply a torque to the rotating member 110, and the torque is greater than the friction force when the rotating member 110 and the housing 200 rotate, so that the support frame 100 can automatically rotate without setting an additional power source to meet the support requirements when the endoscope host 300 is placed horizontally or vertically.

[0063] In this embodiment, the support member 120 is made of a material with a relatively high density, such as iron, copper, stainless steel, etc. Using a material with a relatively high density can make the support member 120 have a larger mass under the same volume.

[0064] In this embodiment, the maximum rotation angle of the rotating member 110 is preferably 90° to meet the requirements of vertical and horizontal placement of the housing 200.

[0065] like Figure 16-Figure 18 As shown, the housing 200 has a cavity inside, and the housing 200 also has a through hole communicating with the cavity. The rotating member 110 includes a fixed portion 1111, an intermediate portion 1112 and a connecting portion 1113. The fixed portion 1111 is rotatably arranged in the cavity, one axial end of the intermediate portion 1112 passes through the through hole and is connected to the fixed portion 1111, and the other end extends outside the through hole and is connected to the connecting portion 1113, and the support member 120 is arranged on the connecting portion 1113. While ensuring that the rotating member 110 is firmly connected to the housing 200, the rotating member 110 can also be rotated relative to the housing 200 to meet the requirements of vertical or horizontal placement of the housing 200.

[0066] In this embodiment, if Fig.10 and Fig.17 As shown, the fixed portion 1111 is provided with a plurality of first abutting portions 113 on the axial end face, and the first abutting portions 113 abut against the inner wall of the cavity provided in the shell 200, thereby reducing the contact area between the rotating member 110 and the shell 200, thereby reducing the friction force when the rotating member 110 rotates, and ensuring that the torque applied to the rotating member 110 by the support member 120 under the action of gravity can be greater than the friction force when the rotating member 110 and the shell 200 rotate.

[0067] It should be noted that the first abutment portion 113 may be provided on one side or on both sides of the axial end face of the fixing portion 1111. In order to minimize the friction force during the rotation of the rotating member 110, the present embodiment adopts a method in which the first abutment portion 113 is provided on the two axial end faces of the fixing portion 1111 respectively.

[0068] In this embodiment, if Fig.16 and 17 As shown, a plurality of second abutting portions 114 are provided on the end surface of the connecting portion 1113 facing the shell 200, and the second abutting portions 114 abut against the outer surface of the shell 200, thereby further reducing the contact area between the rotating member 110 and the shell 200, thereby reducing the friction force when the rotating member 110 rotates, and better ensuring that the torque applied to the rotating member 110 by the supporting member 120 under the action of gravity can be greater than the friction force when the rotating member 110 and the shell 200 rotate.

[0069] It should be noted that the number of the first abutting portions 113 and the number of the second abutting portions 114 can be flexibly set according to usage requirements, and this embodiment does not limit this.

[0070] It should also be noted that the first abutting portion 113 and the second abutting portion 114 may be in a ring shape, a hemispherical shape or other shapes, and this embodiment does not limit this.

[0071] In this embodiment, if Figure 16-Figure 18 As shown, the middle part 1112 is sleeved with a gasket 210 and is rotatably connected to the through hole through the gasket 210. During the rotation of the rotating member 110, due to the presence of the gasket 210, the rotational friction between the middle part 1112 and the through hole is small, and compared with the method in which the middle part 1112 directly abuts against the through hole, the friction during the rotation of the rotating member 110 is further reduced, and it is better ensured that the torsion applied to the rotating member 110 by the support member 120 under the action of gravity can be greater than the friction during the rotation of the rotating member 110 and the housing 200.

[0072] In this embodiment, if Fig.18 As shown, since the fixing portion 1111 and the middle portion 1112 need to rotate in coordination with the housing 200 , the fixing portion 1111 and the middle portion 1112 are preferably circular.

[0073] In this embodiment, if Fig.18 As shown, the connection portion 1113 is located outside the housing 200 and will not cause motion interference with the housing 200 when rotating. Therefore, the shape of the housing 200 can be circular, elliptical, polygonal or other shapes, which is not limited in this embodiment.

[0074] The support member 120 can rotate around the rotating member 110, so that the support member 120 can be expanded or collapsed. When the support member 120 rotates to the first position, as shown in FIG. Figure 4 As shown, the support member 120 is parallel to the housing 200, and the support member 120 is in a retracted state; when the support member 120 rotates to the second position, as shown Figure 1-Figure 3As shown, the support member 120 and the housing 200 have an angle, and at this time the support member 120 is in an unfolded state, and can support the housing 200 to be placed horizontally or tilted.

[0075] like Figure 7 and Figure 8 As shown, an eccentric wheel 122 is provided at the connection between the support member 120 and the rotating member 110. When the support member 120 rotates to the first position, as shown in FIG. Fig.14 and Fig.15 As shown, the distal end of the eccentric wheel 122 abuts against the housing 200, and the support member 120 is in a retracted state. When the support member 120 is in the retracted state, the endoscope host 300 is often transported, and the rotating member 110 and the support member 120 that are easy to rotate will have a certain impact on the transportation. Therefore, by abutting the eccentric wheel 122 against the housing 200 in the retracted state, the rotation of the support member 120 is limited by friction. At the same time, since the support member 120 is connected to the rotating member 110, the eccentric wheel 122 abuts against the housing 200, and the rotation of the rotating member 110 can also be limited by friction.

[0076] When the support member 120 rotates to the second position, Fig.12 and Fig.13 As shown, the distal end of the eccentric wheel 122 abuts against the rotating member 110, and the support member 120 is in the unfolded state. When the support member 120 is in the unfolded state, it supports the endoscope host 300, so that the endoscope host 300 can be placed horizontally or vertically. In order to form a certain angle between the support member 120 and the housing 200 to meet the demand of supporting the endoscope host 300, the eccentric wheel 122 abuts against the rotating member 110, and the friction force is used to limit the excessive rotation of the rotating member 110. In addition, when the support member 120 rotates to the second position, the distal end of the eccentric wheel 122 separates from the housing 200, so that the rotating member 110 can rotate.

[0077] It should be noted that the contact point between the shell 200 and the distal end of the eccentric wheel 122 has a certain deformation capacity. When subjected to an external force of a certain magnitude, the rotating member 110 rotates so that the distal end of the eccentric wheel 122 squeezes the shell 200. The shell 200 is deformed by the force, so that the distal end of the eccentric wheel 122 can enter the rotating member 110.

[0078] In this embodiment, the angle between the first position and the second position may be 30°, 40°, 50° or others, which is not limited in this embodiment.

[0079] like Figure 5As shown, the rotating member 110 has a mounting hole 111, and one end of the supporting member 120 extends into the mounting hole 111 to achieve a rotating connection between the supporting member 120 and the rotating member 110, so that the supporting member 120 can rotate between a first position and a second position.

[0080] In some embodiments, there is one mounting hole 111 disposed on the outer peripheral wall of the rotating member 110 . Accordingly, there is one end of the supporting member 120 corresponding to the mounting hole 111 , which is rotatably connected to the mounting hole 111 .

[0081] In some embodiments, there are two mounting holes 111, which are respectively disposed on the outer peripheral walls of the rotating member 110 on both sides of the radial direction. Correspondingly, there are also two ends of the supporting member 120 corresponding to the mounting holes 111, which are rotatably connected to the mounting holes 111 respectively.

[0082] like Figure 6 As shown, the mounting hole 111 has a limiting portion 112 , and when the supporting member 120 rotates to the second position, the distal end of the eccentric wheel 122 abuts against the limiting portion 112 .

[0083] As a preferred mode of this embodiment, the width of the limiting portion 112 along the diameter direction of the mounting hole 111 is greater than the diameter of the mounting hole 111. Such an arrangement enables the distal end of the eccentric wheel 122 to rotate into the limiting portion 112 and stop against the inner wall of the limiting portion 112.

[0084] The limiting portion 112 has an opening on one side facing the housing 200, so that the limiting portion 112 is in communication with the housing 200. When the support member 120 rotates from the first position to the second position, the distal end of the eccentric wheel 122 enters the limiting portion 112 through the opening and abuts against the limiting portion 112. Similarly, when the support member 120 rotates from the second position to the first position, the distal end of the eccentric wheel 122 leaves the limiting portion 112 through the opening and abuts against the housing 200.

[0085] In some embodiments, the limiting portion 112 is located at the head of the mounting hole 111 and communicates with the outside.

[0086] In some embodiments, the limiting portion 112 is disposed inside the rotating member 110 .

[0087] Among them, this embodiment preferably adopts a method in which the limiting portion 112 is located at the head of the installation hole 111, which makes it easier to install the support member 120 on the rotating member 110.

[0088] like Figure 9-11As shown, the locking assembly 130 includes a plurality of limit blocks 131, which are arranged along the circumference of the rotating member 110 and are respectively slidably connected to the housing 200. When sliding, the limit blocks 131 can move toward or away from the axis of the rotating member 110; the outer peripheral wall of the rotating member 110 is provided with one of a protrusion 133 and a slot 115, and the limit block 131 is provided with another one on the end surface close to the rotating member 110, and the protrusion 133 is engaged with the slot 115 to limit the rotation of the rotating member 110.

[0089] When the endoscope host 300 switches between horizontal placement and vertical placement, if the support assembly is too flexible relative to the housing 200, the stability of the support member 120 is poor. Therefore, the protrusion 133 is inserted into the slot 115 to fix the rotating member 110 in a suitable position.

[0090] As a preferred embodiment of the present invention, the number of the limit blocks 131 is two. The angle between the two limit blocks 131 is 90°, wherein the moving direction of one limit block 131 is parallel to the length direction of the housing 200, and the moving direction of the other limit block 131 is parallel to the width direction of the housing 200. When the housing 200 is placed vertically or horizontally, the protrusion 133 is inserted into the slot 115, so that the rotating member 110 does not rotate, thereby ensuring the stability of the support member 120. It is understood that the number of the limit blocks 131 can also be three, four or other numbers, thereby limiting the rotation of the rotating member 110 at more angles, which is not limited in the present embodiment.

[0091] In some embodiments, the protrusion 133 is disposed on the limiting block 131 , and the locking groove 115 is disposed on the outer peripheral wall of the rotating member 110 .

[0092] In some embodiments, the protrusion 133 is disposed on the outer peripheral wall of the rotating member 110 , and the locking groove 115 is disposed on the limiting block 131 .

[0093] In this embodiment, if Fig. 9 and Fig.11 As shown, the limit block 131 is provided with a slide groove 1311, which extends along the length direction of the limit block 131, and the housing 200 is provided with a connecting block 201, which is embedded in the slide groove 1311, so that the limit block 131 is slidably connected to the housing 200. Through the cooperation between the connecting block 201 and the slide groove 1311, the limit block 131 can be prevented from falling off from the housing 200, the movement of the limit block 131 can be guided, and the maximum sliding stroke of the limit block 131 can be limited.

[0094] In this embodiment, if Fig. 9As shown, when the protrusion 133 is inserted into the slot 115 , the protrusion 133 is completely fitted with the slot 115 , thereby preventing the rotating member 110 from rotating within a small range, and further ensuring the stability of the supporting member 120 .

[0095] In this embodiment, if Figure 1-Figure 4 As shown, when the protrusion 133 is inserted into the slot 115 , the bottom of the limit block 131 is coplanar with the end surface of the shell 200 , so that the contact area between the shell 200 and the placement surface is large, thereby making the shell 200 more stably placed.

[0096] In this embodiment, if Fig. 9 and Fig.11 As shown, the end face of the limit block 131 corresponding to the rotating member 110 has an arc-shaped surface, and the curvature of the arc-shaped surface is exactly the same as the curvature of the outer wall of the rotating member 110, so that the arc-shaped surface can completely fit the outer wall of the rotating member 110, thereby making the contact area between the limit block 131 and the rotating member 110 large. When the protrusion 133 is inserted into the slot 115, the rotation of the rotating member 110 can be better limited, and the stability of the support member 120 is further guaranteed.

[0097] like Fig.11 As shown, the protrusion 133 has two inclined guide surfaces 1331. In the embodiment where the protrusion 133 is arranged on the rotating member 110, the two guide surfaces 1331 are moved inward from the stop block 131 by the rotating member 110. In the embodiment where the protrusion 133 is arranged on the stop block 131, the two guide surfaces 1331 are moved inward from the stop block 131 by the rotating member 110.

[0098] Due to the existence of the guide surface 1331, when the endoscope mainframe 300 is switched from horizontal placement to vertical placement, or from vertical placement to horizontal placement, the support member 120, under the action of gravity, will apply torque to the rotating member 110 to drive the rotating member 110 to rotate. During the rotation of the rotating member 110, due to the existence of the guide surface 1331, the protrusion 133 will be easily separated from the slot 115, without the need to manually slide the limit block 131. The rotation of the rotating member 110 automatically separates the protrusion 133 and the slot 115, so as to meet the operator's single-handed operation during the operation, so that the endoscope mainframe 300 can be switched to horizontal placement or vertical placement. Support requirements.

[0099] like Fig. 9As shown, the locking member further includes a resilient member. When the protrusion 133 is aligned with the slot 115, the resilient member drives the limit block 131 to move toward the rotating member 110, so that the protrusion 133 is inserted into the slot 115. When the endoscope host 300 is switched from horizontal placement to vertical placement, or from vertical placement to horizontal placement, the protrusion 133 will be aligned with the slot 115. At this time, the resilient member applies a force to the limit block 131 to move toward the rotating member 110, so that the protrusion 133 is inserted into the slot 115 to limit the rotation of the rotating member 110, and there is no need to manually slide the limit block 131, so as to meet the operator's use requirements of single-handed operation during surgery.

[0100] In some embodiments, the resilient member includes an elastic member 132. The elastic member 132 is disposed in the slide groove 1311, one end of the elastic member 132 is connected to the slide groove 1311, and the other end is connected to the connecting block 201. When the support member 120 applies a torque to the rotating member 110 under the action of gravity and drives the rotating member 110 to rotate, and the protrusion 133 is separated from the slot 115, the limit block 131 will move in a direction away from the rotating member 110 and squeeze the elastic member 132. As the rotating member 110 continues to rotate, the protrusion 133 will also align with the slot 115. At this time, the elastic potential energy stored in the elastic member 132 when it is squeezed is released, driving the limit block 131 to move toward the rotating member 110, so that the protrusion 133 is stuck in the slot 115.

[0101] In this embodiment, the elastic member 132 may be a coil spring, a spring sheet or others, which is not limited here.

[0102] In some embodiments, the resilient member includes a plurality of magnets. The plurality of magnets are divided into a first magnet and a second magnet, and the first magnet and the second magnet attract each other. The first magnet is arranged on the protrusion 133, and the second magnet is arranged on the slot 115. When the support member 120 applies a torque to the rotating member 110 under the action of gravity and drives the rotating member 110 to rotate, and the protrusion 133 separates from the slot 115, the first magnet and the second magnet will gradually separate. As the rotating member 110 continues to rotate, the protrusion 133 will also align with the slot 115. At this time, the first magnet and the second magnet attract each other, driving the limit block 131 to move toward the rotating member 110, so that the protrusion 133 is stuck in the slot 115.

[0103] It should be noted that, no matter whether the embodiment using the elastic member 132 or the embodiment using the magnet is used, the torque applied by the support member 120 to the rotating member 110 under the action of gravity is sufficient to separate the protrusion 133 and the slot 115 .

[0104] like Figure 1-Figure 4As shown, the housing 200 has a first placement portion 230 and a second placement portion 240 . When the housing 200 is placed vertically, the first placement portion 230 supports the housing 200 . When the housing 200 is placed horizontally, the second placement portion 240 supports the housing 200 .

[0105] The first placement portion 230 and the second placement portion 240 are perpendicular to each other, the first placement portion 230 is a side wall in the width direction of the housing 200, and the second placement portion 240 is a side wall in the length direction of the housing 200. When the housing 200 is placed vertically or horizontally, the first placement portion 230 or the second placement portion 240 has a large contact area with the placement surface, so that the housing 200 can be placed stably.

[0106] like Fig.12 , Fig.14 and Fig.16 As shown, the distance between the axis of the rotating member 110 and the first placement portion 230 is equal to the distance between the axis of the rotating member 110 and the second placement portion 240. With such a configuration, when the housing 200 is switched between vertical placement and horizontal placement, it can be ensured that the angle between the housing 200 and the placement surface is the same when the housing 200 is placed vertically and horizontally, and the placement mode of the endoscope host 300 is switched in time, and the tilt angle of the endoscope host 300 will not change, which is more in line with the operator's use requirements during surgery.

[0107] like Figure 1-Figure 4 As shown, the support member 120 has a support portion 121. When the housing 200 is placed vertically, the support portion 121 is parallel to the first placement portion 230. When the housing 200 is placed horizontally, the support portion 121 is parallel to the second placement portion 240.

[0108] Due to the existence of the support portion 121, no matter whether the shell 200 is placed vertically or horizontally, the contact area between the support portion 121 and the placement surface is larger, which better ensures that the support member 120 has sufficient stability to meet the requirements of supporting the endoscope host 300.

[0109] In this embodiment, the support member 120 is trapezoidal to better support the housing 200. The gravity applied by the housing 200 to the support member 120 can be well transferred to the support portion 121 through both sides of the support member 120, thereby better ensuring that the support member 120 has sufficient stability to meet the requirements of supporting the endoscope host 300.

[0110] like Figure 1 and Figure 2As shown, the housing 200 is used to install the endoscope host 300, or the housing 200 can be a part of the endoscope host 300. With the above two methods, the support frame 100 can support the endoscope host 300, and it can also be operated with one hand, so that the endoscope host 300 can be switched between horizontal placement and vertical placement. The two methods can be flexibly selected according to the use requirements, and this embodiment does not limit this.

[0111] Some embodiments of the present application provide an endoscope host 300, such as Figure 1 As shown, there is a support frame 100 .

[0112] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0113] In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in a reverse order according to the functions involved. For example, the described methods may be performed in an order different from that described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

[0114] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
