[0001] This application belongs to the technical field of medical auxiliary devices, and more specifically, relates to an endoscope protection device. Background Technology

[0002] Currently, endoscopic technology is widely used in the fields of medical diagnosis and treatment. An endoscopic device typically consists of a tubular structure equipped with a light source and a camera. It is inserted into the body through natural openings or small incisions, providing clear images that allow doctors to observe lesions within the patient's body and perform corresponding treatment procedures, thus assisting doctors in diagnosis and treatment.

[0003] When an endoscope is not in use or is temporarily placed, it is usually placed on the operating table. Medical staff may accidentally touch the endoscope while performing other medical procedures, or other equipment or tools may accidentally collide with the endoscope, which can easily cause the endoscope to slip off the operating table and damage the delicate electronic or optical components inside the endoscope. Utility Model Content

[0004] The purpose of this application is to provide an endoscope protection device to solve the problem in the prior art that the endoscope is easily dropped and damaged when placed in an unstable position.

[0035] This application provides an endoscope protection device for fixing an endoscope, thereby protecting it from damage by external factors. (See reference...) Figure 1 and Figure 2 The endoscope protection device provided in this application includes: a base 100, a support component 200, and an airbag component 300.

[0036] The base 100 can be a support structure of any shape, used to provide a mounting position for the support assembly 200 and the airbag assembly 300. The base 100 has a receiving cavity 1001, which is a cavity structure of any shape. The shape of the receiving cavity 1001 can match the shape of the endoscope, and its size is larger than the size of the endoscope so that the endoscope can slide horizontally into the receiving cavity 1001.

[0037] In this embodiment, the base 100 includes a first base 110 and a second base 120. The first base 110 has a cuboid structure, and the second base 120 is located above the first base 110. Both ends of the second base 120 extend downwards and are connected and fixed to the first base 110, such that a portion of the lower surface of the second base 120 is spaced apart from the upper surface of the first base 110, forming a receiving cavity 1001 with a size larger than the diameter of the endoscope. A support assembly 200 can be installed on the first base 110 to detect whether an endoscope is placed in the receiving cavity 1001. An airbag assembly 300 can be installed on the second base 120, and after the support assembly 200 detects that the endoscope is placed in the receiving cavity 1001, it applies downward pressure to the endoscope, firmly fixing the endoscope in the receiving cavity 1001, making the endoscope less susceptible to movement by external forces, and achieving the purpose of protecting the endoscope.

[0038] Reference Figure 3 The support assembly 200 includes a support 210 disposed on the base 100 and a position detector 220. The support 210 is located at the bottom of the receiving cavity 1001 and is used to support an endoscope that enters the receiving cavity 1001. The position detector is used to detect whether an endoscope is present on the support 210.

[0039] The support 210 can be installed on the top of the first base 110 and protrudes from the upper surface of the first base 110. After the endoscope is inserted into the receiving cavity 1001, it can be placed on the support 210, which supports the endoscope. The position detector 220 can be any sensor that can detect the presence or position of an object, such as a pressure sensor, photoelectric sensor, or infrared sensor. When the position detector 220 detects that the endoscope has been placed on the support 210, the airbag assembly 300 can be used to apply pressure to the endoscope to secure it firmly.

[0040] The airbag assembly 300 includes a protective airbag 310, an air pump 320, and a control valve 330. The protective airbag 310 is located at the top of the receiving cavity 1001 and has two ports: an input port and an output port. The air pump 320 is connected to the input port of the protective airbag 310. The control valve 330 is normally closed and connected to the output port of the protective airbag 310. Both the air pump 320 and the control valve 330 are electrically connected to the position detector 220. The air pump 320 inflates the protective airbag 310 when the position detector 220 detects the presence of an endoscope on the support 210, causing the airbag assembly 300 to expand towards the receiving cavity 1001. The control valve 330 opens when the position detector 220 detects that no endoscope is present on the support 210, causing the protective airbag 310 to deflate and contract.

[0041] The airbag is made of highly elastic materials such as silicone rubber or polyurethane, and has a hollow spherical or ellipsoidal structure that can inflate or deflate. The air pump 320 can be a miniature air pump or a small compressor, which compresses external air and pumps it into the protective airbag 310 to inflate it. A vent 1003 is provided on the second seat 120 corresponding to the air pump 320, allowing the gas pumped in by the air pump 320 to enter the protective airbag 310. The control valve 330 can be a solenoid valve or a mechanical valve, and its output port passes through the second seat 120 to communicate with the external space. The control valve 330 is normally closed, so gas will not escape from the airbag when it is inflated. When the control valve 330 is opened, the gas inside the airbag is compressed by the elastic force of the airbag and is expelled through the output port of the control valve 330, causing the airbag to contract. The positions of the air pump 320 and the exhaust valve can be determined according to actual needs. In this embodiment, the air pump 320 and the exhaust valve are both installed inside the second seat 120 and are located at the two extension ends of the airbag, respectively.

[0042] The operation of both the air pump 320 and the control valve 330 is controlled by the position detector 220. When the position detector 220 detects an endoscope on the support 210, the air pump 320 starts and inflates the protective airbag 310, causing the airbag 310 to expand and fit tightly against the endoscope, thus securing it firmly within the receiving cavity 1001. When the position detector 220 detects that no endoscope is on the support 210, the control valve 330 opens, and the gas inside the protective airbag 310 is released through the control valve 330, causing the protective airbag 310 to contract for the next use.

[0043] In addition, an air pump 320 with both inflation and deflation functions can be used. In this case, the protective airbag 310 can be connected to the air pump 320 with only one port. When the position detector 220 detects that there is an endoscope on the support 210, the air pump 320 is used to inflate the protective airbag 310. When the position detector 220 detects that there is no endoscope on the support 210, the air pump 320 is used to reverse the operation to extract the gas from the protective airbag 310.

[0044] In practical applications, a controller can also be set up. The position detector 220, air pump 320, and control valve 330 are all electrically connected to the controller, so that the controller can control the working status of the air pump 320 and the control valve 330. The controller can be a programmable controller such as a microcontroller or PLC, or it can be a dedicated control chip. Based on the signal sent by the position detector 220, the controller determines whether an endoscope is on the support 210, and accordingly controls the air pump 320 to inflate the protective airbag 310 or controls the control valve 330 to open to release the gas in the airbag.

[0045] Reference Figure 2The second housing 120 can be constructed by splicing a front housing 120a and a rear housing 120b, which are symmetrically arranged. The airbag assembly 300 is fixed between the front housing 120a and the rear housing 120b to facilitate the assembly of the overall structure. Fillers can be provided inside the front housing 120a and the rear housing 120b at positions corresponding to the air pump 320 and the control valve 330. The fillers have grooves that match the shapes of the air pump 320 and the control valve 330 to accommodate them and maintain structural stability within the second housing 120. The fillers can be made of flexible materials, such as sponge or foam, or of rigid materials with low hardness, such as plastic, to provide shock absorption and fixation for the air pump 320 and the control valve 330.

[0046] Reference Figure 3 and Figure 4 In some embodiments, the support assembly 200 further includes an elastic element 230, the support seat 210 is slidably connected to the base 100 in the vertical direction, the elastic element 230 is connected between the support seat 210 and the base 100, and is used to apply an upward elastic force to the support seat 210; the position detector 220 can determine that there is an endoscope on the support seat 210 when the support seat 210 moves downward to a preset position.

[0047] Specifically, the first seat 110 can be a shell structure with a hollow interior forming an installation cavity 1002, and the top of the first seat 110 has an opening that matches the shape of the support seat 210, so that the support seat 210 can slide and connect to the installation cavity 1002 in the vertical direction.

[0048] The elastic element 230 can be any elastic structure such as a spring or elastic sheet, with one end connected to the bottom of the support seat 210 and the other end connected to the bottom of the mounting cavity 1002. In this embodiment, the elastic element 230 is a vertically arranged helical spring. A support cylinder 212 protrudes downward from the bottom of the support seat 210. A support plate 111 is provided inside the mounting cavity 1002 of the first seat 110. The support plate 111 is located below the support seat 210, and a positioning post protrudes upward from the top surface of the support plate 111. The top end of the elastic element 230 is built into the support cylinder 212, and the bottom end abuts against the support plate 111 and surrounds the positioning post to provide an installation position for the elastic element 230, so that the elastic element 230 provides an upward elastic force to the support seat 210.

[0049] When no endoscope is placed on the support 210, the elastic element 230 applies an upward elastic force to the support 210, causing part of the support 210 to extend out of the mounting cavity 1002. When an endoscope is placed on the support 210, the weight of the endoscope causes the support 210 to move downward and compress the elastic element 230. When the support 210 moves downward to a preset position, the position detector 220 can detect the presence of an endoscope on the support 210. At this time, the airbag assembly 300 can apply downward pressure to the endoscope to fix its position. When the user removes the endoscope from the receiving cavity 1001, the support 210 loses the weight of the endoscope, and the elastic element 230 returns to its original shape, causing the support 210 to move upward and reset. At this time, the support 210 is no longer in the preset position, so the position detector 220 can no longer detect the presence of an endoscope on the support 210. The airbag assembly 300 can then be controlled to stop applying downward pressure, making it easy to reinsert the endoscope into the receiving cavity 1001.

[0050] Combination Figures 4-7 As shown, in this embodiment, the position detector 220 is a pressure sensor disposed below the support 210. A position detection rod 211 protrudes downward from the bottom of the support 210, and the position detection rod 211 can abut against the pressure sensor when the support 210 moves downward to a preset position.

[0051] The position detection rod 211 can be any shape. When the support cylinder 212 is provided at the bottom of the support base 210, the position detection rod 211 can be fixed to the outer wall of the support cylinder 212. The position detector 220 can be installed on the upper surface of the support plate 111 and located directly below the position detection rod 211. When the endoscope is placed on the support base 210, the support base 210 moves downward under force, causing the position detection rod 211 to move downward synchronously until the position detection rod 211 touches the pressure sensor. At this time, the pressure sensor detects a pressure signal, thus confirming the presence of the endoscope on the support base 210. Conversely, when the endoscope is removed from the support base 210, due to the restoring force of the elastic element 230, the support base 210 will move upward to its initial position. At this time, the position detection rod 211 is lifted as the support base 210 rises, leaving the surface of the pressure sensor. The pressure sensor will then sense the disappearance of pressure, thus confirming that the endoscope has been removed from the support base 210.

[0052] In other embodiments, the position detector 220 can be a distance sensor, and the position detection rod 211 is provided with a trigger part, which can correspond to the position of the distance sensor when the support 210 moves downward to a preset position.

[0053] Reference Figure 8The trigger part can be a protrusion 2111 protruding towards the distance sensor. When the support 210 is subjected to force and moves downward, the protrusion 2111 moves synchronously with the position detection rod 211 until the protrusion 2111 moves into the detection range of the distance sensor. At this time, the distance sensor detects the protrusion 2111 and can determine that there is an endoscope on the support 210.

[0054] Reference Figure 9 The triggering part can also be a hollow portion 2112 formed in the position detection rod 211. The hollow portion 2112 is a through hole 2102 of any shape and is located on the upper part of the position detection rod 211. When no endoscope is placed on the support 210, the part of the position detection rod 211 without the hollow portion 2112 corresponds to the side of the distance sensor, allowing the distance sensor to detect the position detection rod 211. When the support 210 is subjected to force and moves downward, the hollow portion 2112 moves synchronously with the position detection rod 211 until the hollow portion 2112 moves into the detection range of the distance sensor, thereby causing the position detection rod 211 to leave the detection range of the distance sensor. At this time, the distance sensor loses its sensing of the position detection rod 211.

[0055] Furthermore, the upper surface of the support 210 is provided with a positioning groove 2101 for embedding the endoscope. Specifically, the shape of the positioning groove 2101 can match the shape of the endoscope so that the endoscope can be stably placed in the positioning groove 2101, preventing it from shaking or shifting within the receiving cavity 1001. The positioning groove 2101 helps to further improve the stability and fixation of the endoscope within the protective device. The airbag can be positioned directly above the opening of the positioning groove 2101 to apply downward pressure to the endoscope, achieving a stable fixation effect.

[0056] Optionally, the positioning groove 2101 is a flared shape that gradually expands from bottom to top. This facilitates the endoscope's sliding into the receiving cavity 1001 along the guide of the flared positioning groove 2101 and its stable placement within the positioning groove 2101. In this embodiment, the positioning groove 2101 has an upward-facing V-shaped structure with two symmetrical inclined sidewalls, which better guides the endoscope into the positioning groove 2101 and effectively prevents the endoscope from shaking or shifting within the receiving cavity 1001.

[0057] In addition, the positioning groove 2101 can also be a U-shaped, semi-circular, arc-shaped or other suitable shape with the opening facing upward, to accommodate endoscope lenses of different shapes and ensure that the endoscope can be stably placed in the positioning groove 2101.

[0058] Furthermore, the inner wall of the positioning groove 2101 is provided with a rotatable support roller 240.

[0059] Understandably, when the user removes the endoscope from the receiving cavity 1001, because the endoscope is not completely detached from the support 210, the airbag continues to apply downward pressure to the endoscope, causing hard friction between the endoscope and the support 210 during the removal of the receiving cavity 1001, resulting in scratches or wear on the lens surface. By providing a rotatable support roller 240 on the inner wall of the positioning groove 2101, when the user removes the endoscope from the receiving cavity 1001, the support roller 240 can rotate with the movement of the endoscope, thereby changing the sliding friction to rolling friction, significantly reducing the friction between the endoscope and the support 210. This avoids scratches or wear on the endoscope lens surface caused by friction, improving the endoscope's service life and protective effect.

[0060] In this embodiment, the positioning groove 2101 has a V-shaped structure, and support rollers 240 are provided on the inclined inner walls on both sides. A through hole 2102 can be opened on the inner wall of the positioning groove 2101. The shape of the through hole 2102 matches the shape of the support roller 240. The support roller 240 is embedded in the through hole 2102 and partially protrudes from the inner wall of the positioning groove 2101 so as to contact the endoscope placed in the positioning groove 2101. The overall structure is also more compact.

[0061] Furthermore, in this embodiment, the bottom opening of the first seat 110 allows the support seat 210, elastic element 230, and support plate 111 to be sequentially installed into the mounting cavity 1002 of the first seat 110 from bottom to top, facilitating the assembly and disassembly of each component. This also aids in the maintenance and repair of internal components, improving the maintainability of the endoscope protection device.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
