[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0038] An endoscope is a commonly used medical device that features an imaging module that allows it to penetrate the human body through natural openings or surgical incisions to observe lesions. Some endoscopes have a zoom function, with the movable lens group moving along the optical axis to change the imaging focal length. As the movable lens group moves along the optical axis, it is prone to radial runout due to the gap between it and the inner wall of the housing in which it is housed, resulting in unstable movement.

[0039] In particular, when the movable mirror group is driven by magnetic force, there is a gap between the movable mirror group and the inner wall of the housing, which makes the movable mirror group more likely to move radially, resulting in inaccurate movement of the movable mirror group and possibly affecting the imaging effect.

[0040] Based on the above practical situation, the present invention provides an endoscope imaging module, an endoscope, and an endoscope system. The endoscope imaging module includes a movable lens assembly 10 and an anti-shake assembly 20. The first magnetic structure 13 of the movable lens assembly 10 and the magnetic conductive structure 22 of the anti-shake assembly 20 attract each other, thereby causing the movable lens assembly 10 to be positioned closely against one side of the inner wall of the housing in which it is located, maintaining the radial position of the movable lens assembly 10 and preventing radial runout.

[0041] The endoscope imaging module provided in the embodiment of the present invention is now described.

[0042] Please also refer to Figure 1 and Figure 2 The endoscope imaging module includes a movable lens group 10 and an anti-shake component 20 . The anti-shake component 20 is disposed on the periphery of the movable lens group 10 .

[0043] The movable mirror assembly 10 is capable of moving along its axial direction. The axial directions of the movable mirror assembly 10 and the anti-shake assembly 20 are parallel to the optical axis, while the radial direction of the movable mirror assembly 10 is perpendicular to the axial direction. For ease of description, the axial direction of the movable mirror assembly 10 will be referred to as the axial direction, and the radial direction of the movable mirror assembly 10 will be referred to as the radial direction. A first magnetic structure 13 is provided on the outer peripheral wall of the movable mirror assembly 10. The outer peripheral wall of the movable mirror assembly 10 can be understood as the area of the movable mirror assembly 10 near its outer peripheral surface. The first magnetic structure 13 is made of a magnetic material and can be provided in an area near the outer peripheral surface of the movable mirror assembly 10.

[0044] A magnetic conductive structure 22 is provided on the inner circumferential wall of the anti-shake assembly 20. The inner circumferential wall of the anti-shake assembly 20 can be understood as the portion of the area of the anti-shake assembly 20 close to its inner circumferential surface. The magnetic conductive structure 22 can be provided in the area close to the inner circumferential surface of the anti-shake assembly 20. The magnetic conductive structure 22 is made of a metal material that can be attracted by the first magnetic structure 13. The materials of the magnetic conductive structure 22 include, but are not limited to, iron, cobalt, nickel, and alloys thereof, including alloys such as pure iron, steel (containing iron), cobalt alloys, and nickel alloys. The magnetic conductive structure 22 can also be made of non-metallic materials that can be attracted by the first magnetic structure 13, such as iron oxide, zinc oxide, manganese-zinc ferrite, silicon nitride, ceramic materials, etc.

[0045] Because the first magnetic structure 13 is disposed on the outer peripheral wall of the movable lens group 10 and the magnetic conductive structure 22 is disposed on the inner peripheral wall of the anti-shake assembly 20, the first magnetic structure 13 and the magnetic conductive structure 22 are disposed adjacent to each other. A magnetic attraction force is generated between the first magnetic structure 13 and the magnetic conductive structure 22, thereby causing the movable lens group 10 to deflect toward one side of the anti-shake assembly 20, thereby causing the movable lens group 10 to be closely attached to one side of the fixed lens group, thereby preventing the movable lens group 10 from jumping in the radial direction. The fixed lens group is a fixed lens group, and the movable lens group 10 can move axially relative to the fixed lens group. The fixed lens group can be the first end lens group 30 described below.

[0046] The endoscope imaging module in the above embodiment includes a movable lens group 10 and an anti-shake assembly 20. The anti-shake assembly 20 is arranged on the outer periphery of the movable lens group 10. A first magnetic structure 13 is provided on the movable lens group 10, and a magnetic conductive structure 22 is provided on the anti-shake assembly 20. The magnetic force generated between the first magnetic structure 13 and the magnetic conductive structure 22 causes the movable lens group 10 to be arranged close to one side of the fixed lens group, thereby fixing the radial position of the movable lens group 10, reducing the possibility of radial runout of the movable lens group 10, and improving the stability of the movable lens group 10 during axial movement.

[0047] In some embodiments of the present invention, please refer to Figure 1 The first magnetic structure 13 includes at least one first magnetic group 131 distributed sequentially along the axial direction of the movable mirror group 10, and the magnetically conductive structure 22 includes at least one magnetically conductive group 221 distributed sequentially along the axial direction of the movable mirror group 10. The cross-section of the movable mirror group 10 is a plane perpendicular to the axial direction of the movable mirror group 10. All first magnetic structures 13 on the same cross-section of the movable mirror group 10 constitute the aforementioned first magnetic group 131. In other words, the same first magnetic group 131 is distributed along the circumference of the movable mirror group 10. Similarly, the same magnetically conductive group 221 is distributed along the circumference of the anti-shake assembly 20.

[0048] By disposing multiple first magnetic groups 131 in the axial direction, the coverage of the first magnetic structure 13 can be increased, the magnetic attraction between the first magnetic structure 13 and the magnetic conductive structure 22 can be enhanced, and the anti-shake effect on the movable mirror group 10 can be increased.

[0049] In some embodiments, the number of the first magnetic groups 131 is the same as the number of the magnetic conductive groups 221 , and the first magnetic groups 131 and the magnetic conductive groups 221 are arranged in a one-to-one correspondence.

[0050] In some embodiments, there are multiple first magnetic groups 131 and one magnetic conductive group 221. Multiple first magnetic groups 131 are arranged opposite the same magnetic conductive group 221, so that each first magnetic group 131 can generate magnetic attraction with the magnetic conductive group 221, and the actual volume of the first magnetic structure 13 can be reduced, saving the raw materials of the first magnetic structure 13.

[0051] In some embodiments, see Figure 3 and Figure 4 The number of the first magnetic groups 131 is two, A1, A2, A3, and A4 form one first magnetic group 131, and B1, B2, B3, and B4 form another first magnetic group 131.

[0052] In some embodiments of the present invention, the first magnetic group 131 includes a first magnetic unit 1311, and the magnetic conductive group 221 includes a magnetic conductive unit 2211. The first magnetic unit 1311 and the magnetic conductive unit 2211 are arranged opposite each other. That is, on the same cross-section, there is one first magnetic unit 1311 and one magnetic conductive unit 2211. The first magnetic unit 1311 and the magnetic conductive unit 2211 are arranged opposite each other, which can be understood as the first magnetic unit 1311 and the magnetic conductive unit 2211 are positioned at the same circumferential position, and the first magnetic unit 1311 can generate magnetic attraction with the magnetic conductive unit 2211.

[0053] By setting the number of the first magnetic unit 1311 and the number of the magnetic conductive unit 2211 to be one, the movable mirror group 10 is offset toward the side where the first magnetic unit 1311 is provided under the action of the magnetic attraction force, and the movable mirror group 10 can be closely attached to the first end mirror group 30, thereby fixing the radial position of the movable mirror group 10 and preventing the movable mirror group 10 from radially jumping.

[0054] The specific positions of the first magnetic unit 1311 and the magnetic conductive unit 2211 are not limited here. Figure 2 The first magnetic unit 1311 and the magnetic conductive unit 2211 can be arranged on the upper side, lower side, left side or right side of the movable mirror assembly 10.

[0055] In some embodiments of the present invention, please refer to Figure 2The first magnetic group 131 includes a plurality of circumferentially spaced first magnetic units 1311, and the magnetic conductive group 221 includes a plurality of circumferentially spaced magnetic conductive units 2211. The plurality of first magnetic units 1311 and the plurality of magnetic conductive units 2211 are arranged one-to-one in a directly opposed relationship. It is understood that each first magnetic unit 1311 and the corresponding magnetic conductive unit 2211 are located at the same circumferential position, and a corresponding magnetic attraction force can be generated between the two. The number of first magnetic units 1311 and magnetic conductive units 2211 is the same, allowing them to be arranged in a one-to-one correspondence.

[0056] By providing multiple first magnetic units 1311 and multiple magnetic conductive units 2211 , the magnetic force between each first magnetic unit 1311 and magnetic conductive unit 2211 can be adjusted according to usage requirements, so that the sum of the magnetic forces between the first magnetic structure 13 and the magnetic conductive structure 22 meets design requirements.

[0057] In some embodiments of the present invention, the number of the first magnetic units 1311 and the number of the magnetic conductive units 2211 are both two, and the two first magnetic units 1311 are arranged opposite each other in the circumferential direction, or the two first magnetic units 1311 are arranged adjacent to each other in the circumferential direction. The two first magnetic units 1311 and the two magnetic conductive units 2211 are arranged in a one-to-one correspondence. The two first magnetic units 1311 are arranged opposite each other in the circumferential direction, which can be understood as the phase difference between the two first magnetic units 1311 is 180 degrees, such as Figure 2 The two first magnetic units 1311 in the upper and lower parts and the two first magnetic units 1311 in the left and right parts are arranged adjacent to each other in the circumferential direction. It can be understood that the phase difference between the two first magnetic units 1311 is less than 180 degrees. Figure 2 There are two first magnetic units 1311 on the upper middle side and the left side, and two first magnetic units 1311 on the left side and the bottom side.

[0058] When the two first magnetic units 1311 are arranged facing each other in the circumferential direction, the two first magnetic units 1311 and the two magnetic conductive units 2211 respectively generate two magnetic forces. The combined force of the two magnetic forces drives the movable mirror assembly 10 to move radially until it contacts the first end mirror assembly 30. Because the two magnetic forces are directed in opposite directions, the combined force is relatively small, thereby reducing the sliding friction of the movable mirror assembly 10.

[0059] The two first magnetic units 1311 are arranged adjacent to each other in the circumferential direction. When the movable lens assembly 10 is positioned at different angles, the movable lens assembly 10 may be closer to one of the first magnetic units 1311 or closer to the other first magnetic unit 1311 due to the gravity of the movable lens assembly 10. Therefore, the anti-shake assembly 20's ability to prevent radial runout of the movable lens assembly 10 is not affected at different positioning angles of the movable lens assembly 10.

[0060] Optionally, the phase difference between the two first magnetic units 1311 is 90 degrees, so that the movable mirror assembly 10 has at least two radial positions with relatively large phase differences. In other embodiments, the phase difference between the two first magnetic units 1311 can also be 60 degrees, 70 degrees, etc.

[0061] In some embodiments of the present invention, the number of the first magnetic units 1311 and the number of the magnetic conductive units 2211 are both three, wherein two of the first magnetic units 1311 are arranged opposite each other in the circumferential direction, and another first magnetic unit 1311 is located between the two first magnetic units 1311 arranged opposite each other. The three first magnetic units 1311 and the three magnetic conductive units 2211 are arranged in a one-to-one correspondence. Two of the first magnetic units 1311 are arranged opposite each other in the circumferential direction, and the phase difference between the two first magnetic units 1311 is 180 degrees. Another first magnetic unit 1311 is located between the two first magnetic units 1311 arranged opposite each other, and the phase difference between the first magnetic unit 1311 and the first two first magnetic units 1311 is less than 180 degrees.

[0062] The two first magnetic units 1311 are arranged opposite each other, so that the combined force generated by the two oppositely arranged first magnetic units 1311 can be relatively small. When the movable mirror assembly 10 is adsorbed to the magnetic conductive unit 2211 close to one side, the attraction between the two is relatively small, which can reduce the frictional resistance of the movable mirror assembly 10. Even if the movable mirror assembly 10 shakes and falls off, it can be adsorbed to the magnetic conductive unit 2211 on the other side.

[0063] Optionally, the phase difference between two adjacent first magnetic units 1311 is 90 degrees. Figure 2 In the embodiment, the three first magnetic units 1311 may be respectively located on the upper side, the lower side and the left side of the movable mirror assembly 10 , or may be respectively located on the left side, the right side and the upper side of the movable mirror assembly 10 .

[0064] In some embodiments of the present invention, please refer to Figure 2 The number of the first magnetic units 1311 and the number of the magnetic conductive units 2211 are both four, two of which are arranged opposite each other in the circumferential direction, and the other two are arranged opposite each other in the circumferential direction. It can be understood that the four first magnetic units 1311 are spaced apart in the circumferential direction.

[0065] The four first magnetic units 1311 are arranged in pairs, so that when the movable mirror assembly 10 is adsorbed to the magnetic conductive unit 2211 close to one side, the attraction between the two is small, which can reduce the friction resistance of the movable mirror assembly 10. Even if the movable mirror assembly 10 shakes and falls off, it can be adsorbed to the magnetic conductive unit 2211 on the other side.

[0066] Optionally, the four first magnetic units 1311 are circumferentially arranged at equal intervals, and the phase difference between any two adjacent first magnetic units 1311 is 90 degrees, so that the movable mirror assembly 10 has four radial positions with large phase differences.

[0067] Optionally, see Figure 4 In the same first magnetic group 131 , the four first magnetic units 1311 are A1 , A2 , A3 , and A4 .

[0068] In some embodiments of the present invention, the number of the first magnetic units 1311 may also be five, six, etc.

[0069] In some embodiments of the present invention, the first magnetic group 131 includes multiple first magnetic units 1311, and the magnetic conductive group 221 includes one magnetic conductive unit 2211. The direction of the line connecting the centers of the magnetic conductive unit 2211 and the movable mirror assembly 10 coincides with the direction of the combined force of the multiple first magnetic units 1311. There are multiple first magnetic units 1311, arranged circumferentially around the movable mirror assembly 10. Each first magnetic unit 1311 generates a corresponding magnetic field, and the multiple first magnetic units 1311 form a superimposed magnetic field whose direction is the direction of the combined force of the multiple first magnetic units 1311. This allows the movable mirror assembly 10 to deflect toward the side where the magnetic conductive unit 2211 is located under the influence of magnetic attraction, allowing the movable mirror assembly 10 to cling to the first end mirror assembly 30, thereby fixing the radial position of the movable mirror assembly 10 and preventing radial runout of the movable mirror assembly 10.

[0070] In some embodiments, see Figure 5 The first magnetic group 131 includes two first magnetic units 1311, and the magnetic conductive group 221 includes a magnetic conductive unit 2211. The magnetic force directions of the two first magnetic units 1311 are F1 and F2 respectively. The combined force direction of the two first magnetic units 1311 is F0. The center line connecting the magnetic conductive unit 2211 and the movable mirror group 10 is L, and the direction of F0 coincides with the length direction of L.

[0071] In some embodiments of the present invention, the first magnetic structure 13 is made of a permanent magnet, does not require electricity, and has low design and raw material costs.

[0072] In some embodiments of the present invention, the magnetic conductive structure 22 is made of iron, which has a low material cost.

[0073] In some embodiments of the present invention, the magnetic force between the first magnetic structure 13 and the magnetically conductive structure 22 is greater than the weight of the movable mirror assembly 10 and less than twice the weight of the movable mirror assembly 10. If the magnetic force between the first magnetic structure 13 and the magnetically conductive structure 22 is less than the weight of the movable mirror assembly 10, the movable mirror assembly 10 may easily fall off the first end mirror assembly 30, failing to provide anti-shake protection. If the magnetic force between the first magnetic structure 13 and the magnetically conductive structure 22 is greater than twice the weight of the movable mirror assembly 10, the magnetic force between the two is too strong, resulting in excessive sliding friction during movement of the movable mirror assembly 10.

[0074] In some embodiments of the present invention, please refer to Figure 3 and Figure 4 The movable lens assembly 10 includes a movable lens barrel 11 and a movable lens 12 . The movable lens 12 is fixed inside the movable lens barrel 11 . The first magnetic structure 13 is provided on the outer peripheral wall of the movable lens barrel 11 .

[0075] Optionally, an accommodating groove is formed on the outer peripheral wall of the movable lens barrel 11 , and the first magnetic structure 13 is disposed inside the accommodating groove.

[0076] In some embodiments of the present invention, please refer to Figure 6 and Figure 7 The anti-shake assembly 20 includes an anti-shake housing 21 and a magnetic conductive structure 22 . The magnetic conductive structure 22 is fixed to the inner peripheral wall of the anti-shake housing 21 .

[0077] Optionally, an accommodating groove is formed on the inner peripheral wall of the anti-shake housing 21 , and the magnetic conductive structure 22 is disposed inside the accommodating groove.

[0078] Optionally, the anti-shake housing 21 may have a rectangular cross-section with rounded corners. This allows the magnetic conductive structure 22 on the anti-shake housing 21 to be a flat plate, eliminating the need for arc-shaped processing, resulting in lower processing costs. Furthermore, a cavity can be formed between the rectangular anti-shake housing 21 and the other end housings with circular cross-sections, facilitating wiring.

[0079] Optionally, the anti-shake housing 21 is fixedly connected to the first end housing 31 .

[0080] Optionally, the anti-shake housing 21 is the outermost barrel wall in the endoscope imaging module, and a magnetic conductive structure 22 is embedded in the barrel wall.

[0081] In some embodiments of the present invention, please refer to Figure 1 and Figure 2The endoscope imaging module also includes a first end lens assembly 30, a movable lens assembly 10, a first end housing 31 of the first end lens assembly 30, and an anti-shake assembly 20, which are arranged in sequence from the inside out. A second magnetic structure 33 is provided on the inner circumferential wall of the first end lens assembly 30. A driving force for axially moving the movable lens assembly 10 is provided between the first magnetic structure 13 and the second magnetic structure 33. The movable lens assembly 10 is disposed within the first end housing 31, which is in turn disposed within the anti-shake assembly 20. The first end lens assembly 30 and the anti-shake assembly 20 are both fixedly disposed, and the movable lens assembly 10 is axially movable relative to the first end lens assembly 30. Due to the magnetic attraction between the first magnetic structure 13 and the magnetically conductive structure 22, the movable lens assembly 10 adheres closely to one side of the first end lens assembly 30, thereby reducing radial runout of the movable lens assembly 10.

[0082] By providing a second magnetic structure 33 on the first end mirror assembly 30, a magnetic driving force is generated between the first magnetic structure 13 and the second magnetic structure 33, which is used to drive the axial movement of the movable mirror assembly 10. Of the magnetic flux lines formed between the first magnetic structure 13 and the second magnetic structure 33, some are oriented in the axial direction of the movable mirror assembly 10, thereby driving the axial movement of the movable mirror assembly 10.

[0083] In some embodiments, one of the first magnetic structure 13 and the second magnetic structure 33 is an electromagnet, and the other is a powered coil. The moving speed and direction of the movable mirror assembly 10 can be adjusted by adjusting the current magnitude and direction of the powered coil.

[0084] In some embodiments, see Figure 8 and Figure 9 The first end lens group 30 includes a first end shell 31, a first lens 32 and a second magnetic structure 33. The first lens 32 is fixed inside the first end shell 31, and the second magnetic structure 33 is arranged on the outer peripheral wall of the first end lens group 30.

[0085] In some embodiments of the present invention, please refer to Figure 1 and Figure 3 The first magnetic structure 13 includes two first magnetic groups 131 spaced axially apart. The movable mirror assembly 10 further includes a magnetic conductive member 14 that conducts magnetic conduction between the opposite magnetic poles of the two first magnetic groups 131. The first magnetic groups 131 have north poles and south poles. The magnetic conductive member 14 conducts magnetic conduction between the opposite magnetic poles of the two first magnetic groups 131. In other words, the magnetic conductive member 14 conducts magnetic conduction between the north pole of one first magnetic group 131 and the south pole of the other first magnetic group 131, thereby conducting magnetic conduction between the two first magnetic groups 131.

[0086] By conducting the two first magnetic groups 131 , a more complete magnetic circuit is formed between the first magnetic structure 13 and the magnetic conductive structure 22 , thereby reducing magnetic leakage and increasing magnetic field strength. Under the same current, a greater thrust is obtained, thereby ensuring the stability of the operation of the movable mirror group 10 .

[0087] In some embodiments, the magnetic conductive member 14 is made of ferrite.

[0088] In some embodiments of the present invention, please refer to Figure 1 The magnetic poles of the first magnetic groups 131 are oriented radially with respect to the movable mirror assembly 10, and the two first magnetic groups 131 have opposite magnetic pole directions. The magnetic conductive member 14 is disposed on the same side of the two first magnetic groups 131. The magnetic poles of the first magnetic groups 131 are oriented radially with respect to the movable mirror assembly 10, i.e., the north pole and south pole directions of the first magnetic groups 131. Therefore, the side of the first magnetic group 131 closest to the central axis of the movable mirror assembly 10 is one of the north pole and south pole, while the side of the first magnetic group 131 farther from the central axis of the movable mirror assembly 10 is the other of the north pole and south pole. The magnetic poles of the two first magnetic groups 131 have opposite directions. That is, the side of one first magnetic group 131 closest to the central axis of the movable mirror assembly 10 is the north pole, and the side farther from the central axis of the movable mirror assembly 10 is the south pole. The side of the other first magnetic group 131 closest to the central axis of the movable mirror assembly 10 is the south pole, and the side farther from the central axis of the movable mirror assembly 10 is the north pole. The magnetic conductive member 14 conducts electricity between the north pole of one of the first magnetic groups 131 and the south pole of the other first magnetic group 131 .

[0089] By making the magnetic poles of the two first magnetic groups 131 in opposite directions and positioning the N pole of one first magnetic group 131 and the S pole of the other first magnetic group 131 on the same side, the magnetic conductive member 14 can be configured as a sheet, thereby conducting the two first magnetic groups 131 .

[0090] In some embodiments of the present invention, please refer to Figure 1 The axial length of the first magnetic structure 13 is less than or equal to the axial length of the magnetic conductive member 14. The axial length of the first magnetic structure 13 can be understood as the sum of the axial lengths of the first magnetic groups 131 and the axial gaps between the first magnetic groups 131.

[0091] By setting the axial length of the first magnetic structure 13 to be less than or equal to the axial length of the magnetic conductive member 14 , the magnetic conductive member 14 can cover each first magnetic group 131 , and the ability to conduct electricity between two adjacent first magnetic groups 131 is enhanced.

[0092] In some embodiments of the present invention, please refer to Figure 1 and Figure 2The endoscope molding module also includes a second end lens assembly. The first end lens assembly 30 and the second end lens assembly are located at the axial ends of the endoscope imaging module. The second end lens assembly includes a second end housing 41 and a second lens. The second lens is fixed to the second end housing 41. The second end housing 41 can be extended into the interior of the movable lens barrel 11. The second end housing 41 can be fixedly connected to the anti-shake housing 21.

[0093] See also Figure 10 The present invention further provides an endoscope, comprising the endoscope imaging system of any of the above-described embodiments. The endoscope comprises an insertion portion 100, an operating portion 200, a catheter portion 300, and a connecting portion 400, which are sequentially connected. The endoscope molding module may be disposed at the operating portion 200.

[0094] The present invention also provides an endoscope system, comprising the endoscope of any of the above embodiments, a light source device, and an image processor. The light source device is used for illumination, enabling the endoscope to clearly capture images of the interior of the human body, and the image processor is used for storing and processing the captured images, and the image processor can be electrically connected to the sensor.

[0095] The endoscope and endoscope system provided by the present invention adopt the above-mentioned endoscope imaging module, which includes a movable mirror group 10 and an anti-shake component 20. The anti-shake component 20 is arranged on the periphery of the movable mirror group 10. The movable mirror group 10 is provided with a first magnetic structure 13, and the anti-shake component 20 is provided with a magnetic conductive structure 22. The magnetic force generated between the first magnetic structure 13 and the magnetic conductive structure 22 will cause the movable mirror group 10 to be arranged closely to one side of the fixed mirror group, thereby fixing the radial position of the movable mirror group 10, reducing the possibility of radial runout of the movable mirror group 10, and improving the stability of the movable mirror group 10 during axial movement.

[0096] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
