DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] The first embodiment of this application is:

[0033] See also Figures 1-12The ear examination tool includes a camera 101, a light source 102, a protective shell 103, a rotating mechanism and a protective mechanism; the rotating mechanism includes a rotating disk 105 with a through hole 104, a connecting disk 106, a fixed column 107, an inserting column 108, a support seat 114, two support plates 115, a rotating rod 116, two limit assemblies arranged on both sides of the rotating rod 116, a plurality of first rubber protrusions 119, a second rubber protrusion 120, a pillar 121, a slider 122, a first spring 136 and a positioning column 123; the protective mechanism includes a magnet 109, an electromagnet 110, a mounting plate 111, a fixed shaft 112 and an electric push rod 113; the limit assembly includes two supporting rods 117 and two limit blocks 118. The above-mentioned solution solves the problem that the angle of the camera 101 cannot be changed after entering the ear canal, which makes it inconvenient for medical staff to shoot the patient's ear canal in different directions and display it on the display screen, and has low practicality. It can be understood that the above-mentioned solution can be used to protect the camera 101 and reduce costs.

[0034] In this implementation, see Figure 1 、 Figure 2 and Figure 5 The rotating disk 105 is rotatably connected to the protective shell 103 and is located in the middle of the rotating disk 105. The connecting disk 106 is detachably connected to the rotating disk 105. One end of the fixing column 107 is fixedly connected to the connecting disk 106 and is located on one side of the center point of the connecting disk 106, that is, it is eccentrically arranged. The other end of the fixing column 107 is threadedly connected to one end of the insertion column 108. The camera 101 is fixedly connected to the other end of the insertion column 108. The light source 102 is fixedly connected to the other end of the insertion column 108 and surrounds the camera 101. The protective mechanism is disposed in the protective shell 103. Through the threaded connection and electrical connection between the insertion column 108 and the fixing column 107, the camera 101 and the insertion column 108 can be removed for cleaning or fault replacement. During use, the patient sits on the chair and faces the medical staff sideways. The medical staff holds the protective shell 103, aligns the camera 101 with the patient's ear canal entrance, and is located in a downward position in the ear canal entrance, entering the patient's ear canal until the insertion column 108 is completely in the patient's ear canal. The protective shell 103 is connected to the display device through a connecting line on the side away from the outlet. The patient slowly rotates the rotating disk 105 with his fingers, such as slowly turning the index finger, to drive the connecting disk 106 to rotate, and then drive the eccentrically set fixed column 107 to rotate. Since the insertion column 108 with the camera 101 is threadedly connected to the fixed column 107, the camera 101 is driven to rotate in the ear canal, and the images at different positions are captured and transmitted to the display device for processing and display, which is convenient for medical staff to view and assist medical staff in making accurate judgments.

[0035] Among them, see Figure 5 、 Figure 7 The magnet 109 is fixedly connected to the rotating disk 105 and is located in the through hole 104. The magnet 109 is in the shape of a hollow ring with a magnetic property. The electromagnet 110 is fixedly connected to the connecting disk 106. The electromagnet 110 is in the shape of a hollow ring with a hollow interior and is sleeved outside the connecting disk 106. It is connected to the power supply, and the power supply is connected to the controller. The electromagnet 110 is a device that generates electromagnetic energy when energized. It has the characteristics of being magnetic when energized and disappearing when the power is off. The mounting plate 111 is slidably connected to the protective shell 103 and is located on the side of the connecting disk 106 away from the camera 101. One end of the fixed shaft 112 is fixedly connected to the connecting disk 106, and the other end is rotatably connected to the mounting plate 111. The output end of the electric push rod 113 is fixedly connected to the mounting plate 111. The mounting plate 111 has a rotation groove on one side facing the fixed shaft 112, and the fixed shaft 112 rotates with the connecting disk 106, so that the fixed shaft 112 slides along the rotation groove. The electric push rod 113 is connected to the controller and is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. When an ear canal examination is required, the power supply supplies power to the electromagnet 110, so that the electromagnet 110 has a magnetic property opposite to that of the magnet 109, and opposite poles attract each other, so that the rotating disk 105 and the connecting disk 106 are fixed. At this time, rotating the rotating disk 105 can drive the connecting disk 106 to rotate accordingly, thereby driving the camera 101 to rotate accordingly to collect images at different angles and transmit them back to the display device for easy viewing by medical staff. After the inspection is completed, the camera 101 and the insertion column 108 are moved out of the patient's ear canal for cleaning. The controller controls the power supply to the electromagnet 110 to stop supplying power. The electromagnet 110 is not magnetic. At this time, the electric push rod 113 drives the mounting plate 111 to move to the side away from the outlet, and then drives the fixed shaft 112 and the connecting disk 106 to move to the side away from the outlet, so that the connecting disk 106 leaves the through hole 104, and finally drives the camera 101 to retract from the outlet into the protective shell 103, which can protect the camera 101 and avoid damage caused by accidental touch and increase cost. Alternatively, when the camera 101 and the insertion column 108 are not moved out of the patient's ear canal, the electric push rod 113 can be started to drive the camera 101 and the insertion column 108 to move to the protective shell 103, so as to avoid the camera 101 and the insertion column 108 accidentally touching the patient's ear canal when the protective shell 103 is manually moved when they are moved out of the patient's ear canal, causing damage to the patient's ear canal and triggering medical disputes.

[0036] Second, see Figure 1 , the support base 114 is located below the protective shell 103, and the support base 114 can be placed on a table near the patient's ear to facilitate supporting the protective shell 103, avoiding fatigue caused by long-term holding by medical staff, and accidental touch causing damage to the patient's ear. The two support plates 115 are fixedly connected to the top of the support base 114 and are arranged relative to each other. The rotating rod 116 is rotatably connected to the two support plates 115 and is detachably connected to the protective shell 103. The protective shell 103 is supported by the rotating rod 116, the support plate 115 and the support base 114. At the same time, the protective shell 103 can be slowly moved up and down, so that the rotating rod 116 slowly rotates around the support plate 115, thereby realizing the camera 101 entering the ear canal to collect images in different positions. The collection range is wide at one time, which is convenient for medical staff to view.

[0037] Also, see Figure 3 , the two abutting rods 117 are fixedly connected to the rotating rod 116, and the two limiting blocks 118 are fixedly connected to the support seat 114 and abut against the abutting rods 117. The setting of the abutting rods 117 and the limiting blocks 118 can limit the rotation angle of the rotating rod 116, preventing the medical staff from rotating the angle too large, causing the camera 101 or the insertion column 108 to contact the patient's ear canal and be damaged. A plurality of the first rubber protrusions 119 are fixedly connected to the circumferential direction of the rotating disk 105 and are located outside the protective shell 103. The setting of the first rubber protrusions 119 increases the friction with the fingers of the medical staff, thereby facilitating the medical staff to rotate the rotating disk 105, drive the connecting disk 106 to rotate, and place the camera 101 in the corresponding angle range. The second rubber protrusion 120 is fixedly connected to the support seat 114 and contacts the rotating rod 116. The second rubber protrusion 120 is semicircular. During the rotation of the rotating rod 116, it contacts the second rubber protrusion 120, which increases friction and prevents excessive rotation from causing damage to the patient's ear canal.

[0038] See also Figure 9 、 Figure 11 、 Figure 12The rotating rod 116 has a sliding groove 135. The pillar 121 is fixedly connected to the protective shell 103 and slides in the sliding groove 135. The slider 122 slides in the sliding groove 135 and abuts against the pillar 121. The first spring 136 is fixedly connected between the slider 122 and the rotating rod 116. The arrangement of the pillar 121, the slider 122, and the first spring 136 can realize the connection and separation of the protective shell 103 and the support base 114, so that the protective shell 103 can be removed for manual operation or placed on the support base 114 for support examination. The choice can be made according to the situation of medical staff. For example, if the patient's condition is complicated and the examination time is long, or there are many patients and few medical staff, and the same medical staff needs to work for a long time, the support can be connected for ear canal examination. Otherwise, it can be removed for manual examination. It has multiple application scenarios and higher practicality. Specifically, when the protective housing 103 is not connected to the rotating rod 116, the first spring 136 is in a freely extended state. When the protective housing 103 and the rotating rod 116 need to be connected, the slider 122 is pushed toward the rotating rod 116, compressing the first spring 136 and placing the pillar 121 in the sliding slot 135. The slider 122 is released. Under the elastic force of the first spring 136, the slider 122 presses against the pillar 121, securing the pillar 121 between the rotating rod 116 and the slider 122. The rotating rod 116 also has a limiting hole 124 connected to the sliding slot 135. The positioning post 123 is fixedly connected to the pillar 121 and located in the limiting hole 124. The provision of the limiting hole 124 and the positioning post 123 enhances connection stability. Specifically, the slider 122 is moved to the side away from the limiting hole 124, the first spring 136 is compressed, the pillar 121 and the positioning column 123 are placed in the sliding groove 135, and the pillar 121 is slid toward the limiting hole 124 until the positioning column 123 is inserted into the limiting hole 124. The slider 122 is released, and the first spring 136 pushes the slider 122 under the accumulated force. The slider 122 resists the pillar 121, and the shape of the slider 122 facing the pillar 121 is adapted to the pillar 121, further enhancing the connection stability.

[0039] See also Figure 5 、 Figure 6The protective mechanism also includes a fixing assembly, which includes a pulley 126, a locking block 127, a mounting block 125, a second spring 128 and a chain 129. The rotating disk 105 has a groove 130. The pulley 126 is rotatably connected to the protective shell 103. The locking block 127 is slidably connected to the protective shell 103 and is moved and inserted into the groove 130. The mounting block 125 is fixedly connected to the protective shell 103 and is located on the side of the rotating disk 105 away from the opening 134. The two ends of the second spring 128 are fixedly connected to the mounting block 125 and the locking block 127. The two ends of the chain 129 are fixedly connected to the locking block 127 and the mounting plate 111, and are sleeved on the pulley 126. The fixing assembly can realize the positioning of the rotating disk 105. Specifically, when the ear canal is not being inspected, the engaging block 127 is partially located in the groove 130, limiting the rotation of the rotating disk 105. At this time, the second spring 128 is in a freely extended state. When the ear canal needs to be inspected, the electric push rod 113 pushes the mounting plate 111 to move toward the opening 134. Since the chain 129 is fixed to the mounting plate 111, it drives the chain 129 to move, and the other end of the chain 129 is sleeved on the sliding The pulley 126 is fixed to the engaging block 127, thereby driving the chain 129 to slide on the pulley 126, pulling the engaging block 127 toward the pulley 126, disengaging the groove 130, and not limiting the rotating disk 105. At the same time, the second spring 128 is in a stretched state. After the inspection is completed, the electric push rod 113 drives the mounting plate 111 to return to its original position. Under the action of the stored force of the second spring 128, the engaging block 127 is driven to return to the groove 130 and continue to limit the rotating disk 105. This structure can prevent the rotating disk 105 from being accidentally touched and rotated when the ear canal inspection tool is not needed for inspection. The rotating disk 105 is rotated frequently, causing the rotating disk 105 and the protective shell 103 to rotate frequently. Frequent rotation will cause wear. Severe wear will lead to reduced accuracy, making it difficult for medical personnel to rotate and perform ear canal inspection. Severe wear may even cause the connection to fail, making it impossible to rotate, or generate noise or vibration during rotation, affecting the inspection effect.

[0040] Also, see Figure 8The ear examination tool also includes a cover plate 131, a placement plate 132 and a sponge layer 133. The cover plate 131 is threadedly connected to the protective shell 103 and covers the opening 134. The placement plate 132 is fixedly connected to the side of the cover plate 131 facing the opening 134, and the sponge layer 133 is fixedly connected to the placement plate 132. When the inspection is completed and the camera 101 enters the protective shell 103, the cover plate 131 is rotated to cover the opening 134 to seal the protective shell 103. When the cover plate 131 is rotated until the protective shell 103 is in a fastened state, that is, when the cover plate 131 cannot continue to rotate and move toward the protective shell 103, the placement plate 132 is located below the insertion column 108, and the sponge layer 133 is in contact with the insertion column 108 and the camera 101 to support the insertion column 108 and the camera 101, thereby preventing the insertion column 108 and the camera 101 from being suspended in the air for a long time without support, causing the insertion column 108 to bend and deform, thereby avoiding damage to the patient's ear canal due to deviation in the angle adjustment for entering the patient's ear canal, and reducing replacement costs.

[0041] The working / implementation / use principle of the present invention is: when there are many patients, the conditions are more complicated, there are fewer medical staff, and the examination time is long, the patients sit on the chair and lean sideways towards the medical staff, that is, the ear that needs to be examined is close to the medical staff. First, slide the slider 122 toward the inner direction of the rotating rod 116 to compress the first spring 136, place the pillar 121 on the rotating rod 116, and the positioning column 123 is located in the limiting hole 124. Release the slider 122 to connect the protective shell 103 and the rotating rod 116; then place the support base 114 on the table near the patient's ear canal, rotate the cover 131 to detach from the protective shell 103, open the opening 134, and activate the electric push rod 113 by the switch to drive the mounting plate 111 to move toward the side of the opening 134, thereby driving the connecting disk 106 to move into the through hole 104 of the rotating disk 105. The electromagnet 110 is energized and has opposite magnetism to the magnet 109, so that it attracts each other. The camera 101 and the insertion column 108 move out of the protective shell 103 through the opening 134 and enter the patient's ear canal, while driving the chain 129 at the same time. The pulley 126 slides, driving the locking block 127 to move out of the groove 130, and the second spring 128 is stretched; the medical staff rotates the rotating disk 105, thereby driving the connecting disk 106 attracted to it by the magnet 109 and the electromagnet 110 to rotate. Due to the eccentric setting of the fixing column 107, the fixing column 107 connected thereto is driven to rotate, thereby driving the insertion column 108 and the camera 101 to rotate slowly in the patient's ear canal, and collecting images in multiple directions, which is convenient for medical staff to view and make accurate judgments; at the same time, the protective shell 103 can be slowly moved up and down. Under the action of the rotating rod 116, the camera 101 and the insertion column 108 can be driven to move slowly up and down to increase the image collection range. During the rotation of the rotating rod 116, the holding rod 117 and the limit block 118 are used to limit the position and the second rubber protrusion 120 is used to slow down the movement speed.After the inspection is completed, the protective shell 103 is moved to move the camera 101 and the insertion column 108 out of the patient's ear canal, the camera 101 and the insertion column 108 are cleaned, and the electric push rod 113 is started to drive the mounting plate 111 to move away from the opening 134, and the camera 101 and the insertion column 108 then enter the protective shell 103. At the same time, the chain 129 moves toward the side of the pulley 126, and the second spring 128 drives the locking block 127 to move toward the groove 130, inserts into the groove 130, and positions the rotating disk 105. Finally, the cover plate 131 is rotated so that the cover plate 131 covers the opening 134. At the same time, the placement plate 132 and the sponge layer 133 are located below the camera 101 and the insertion column 108 for support. When there are fewer patients, the conditions are simple, there are more medical staff, and the examination time is short, the medical staff directly holds the protective shell 103 to perform ear canal examination without connecting the support 121 and the rotating rod 116. The inspection method is the same as the above steps and will not be repeated here.

[0042] The second embodiment of this application is:

[0043] See also Figure 13 On the basis of the first embodiment, the ear examination device of this embodiment further includes a support and lifting mechanism, which includes a base 201, a screw rod 202, a moving block 203, a motor 204, a gripping rod 205 and an extension plate 206.

[0044] In this embodiment, the support and lifting mechanism can achieve support and vertical adjustment of the protective shell 103, which can adapt to patients of different heights for ear canal examination and facilitate medical staff to pick up the ear canal for examination. Specifically, the base 201 is slidably connected to the support seat 114 and is located below the support seat 114. The motor 204 is fixedly connected to the base 201, the screw rod 202 is fixedly connected to the output end of the motor 204, and the moving block 203 is threadedly connected to the screw rod 202 and fixedly connected to the support seat 114.

The motor 204 is connected to the controller, the screw rod 202 has an external thread, and the moving block 203 has an internal threaded hole adapted to the external thread. The motor 204 drives the screw rod 202 to rotate, thereby driving the moving block 203 to move up and down. Since the support seat 114 is fixed to the moving block 203, the support seat 114 is driven to move up and down, thereby driving the protective shell 103 to move up and down. The gripping rod 205 makes it easier for medical staff to pick up the protective shell 103, so that the protective shell 103 can move up and down at an angle under the action of the rotating rod 116, and it is also easier for medical staff to pick up the protective shell 103 separately for ear canal examination. The setting of the extension plate 206 enables the protective shell 103 to be located on the support seat 114 after being connected to the rotating rod 116, so as to support the gripping rod 205 and reduce the labor intensity of medical staff.
