Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to an endoscope device and endoscope system. Background Technology

[0002] An endoscope is a commonly used medical device that is inserted into the body through natural openings or small surgical incisions to perform examinations or other minimally invasive surgeries. When doctors use endoscopes and other medical instruments to perform surgical procedures, they often need to operate on different instruments simultaneously.

[0003] For example, when examining lesions in the pancreas and bile ducts and acquiring images, doctors need to operate three instruments simultaneously: an endoscope, a pancreaticobiliary imaging catheter, and biopsy forceps. These three instruments are independent; in other words, if a doctor needs to complete the procedure independently, they must operate two instruments with one hand. Generally, doctors will operate the endoscope simultaneously with the other instrument. However, operating two instruments with one hand is difficult. Summary of the Invention

[0079] Figure 1 This is a schematic diagram of the endoscope system 10 provided in this embodiment. Figure 2 This is a structural schematic diagram of the connecting frame 120 in the endoscope device 100 provided in this embodiment. Please refer to the diagram. Figure 1 and Figure 2 This embodiment provides an endoscope device 100, and correspondingly, an endoscope system 10 is provided.

[0080] The endoscope system 10 includes an endoscope device 100 and a imaging device (not shown). The imaging device is electrically connected to the endoscope device 100 to display the image information acquired by the endoscope device 100. Optionally, the endoscope device 100 may also include an auxiliary medical device 200.

[0081] The endoscope device 100 includes an endoscope body 110 and a connecting frame 120. The endoscope body 110 has a conventional endoscope structure. Specifically, the endoscope body 110 includes an operating part 111 and a cable 112. One end of the cable 112 is a fixed end 113, which is fixedly connected to the operating part 111. The other end of the cable 112 is used to connect to a light guide connector (not shown). Since the endoscope body 110 has a conventional structure, the connection position between the fixed end 113 and the operating part 111 is also conventional. The connecting frame 120 includes a frame 121 and a first connecting part 130 and a second connecting part 140 disposed at both ends of the frame 121. The first connecting part 130 is connected to the fixed end 113, and the second connecting part 140 is used to connect an auxiliary medical device 200. That is, the endoscope body 110 and the auxiliary medical device 200 are connected through the connecting frame 120, facilitating one-handed operation of both medical devices.

[0082] Since the connecting bracket 120 connects to the endoscope body 110 via the fixed end 113 of the endoscope body 110 itself, the connection between the endoscope body 110 and the auxiliary medical device 200 can be achieved without modifying the structure of the endoscope body 110. At the same time, the fixed end 113 is located at the upper end of the operating part 111 and is basically at the same height as the operating knobs on the operating part 111. Therefore, after the auxiliary medical device 200 is connected through the second connecting part 140, it can be basically at the same height as the operating part 111, which makes it easier for doctors to operate the endoscope body 110 and the auxiliary medical device 200 with one hand, and helps to reduce the difficulty of surgery.

[0083] The endoscope device 100 provided in this application will be further described below:

[0084] Figure 3 This is a structural schematic diagram of the connecting bracket 120 in another state of the endoscope device 100 provided in this embodiment. Please refer to the reference. Figures 1-3 In this embodiment, the first connecting portion 130 includes a first clamping portion 131 and a second clamping portion 132 connected to each other, and the first clamping portion 131 and / or the second clamping portion 132 are connected to the frame 121. A clamping through hole 137 is formed between the first clamping portion 131 and the second clamping portion 132, and the fixed end 113 is clamped and fixed in the clamping through hole 137, thereby realizing the connection between the first connecting portion 130 and the fixed end 113.

[0085] Figure 2 and Figure 3 The structure of the first type of first connecting part 130 is shown exemplarily, such as Figure 2 and Figure 3 The first clamping part 131 is fixedly connected to the frame 121, and the second clamping part 132 is rotatably connected to the first clamping part 131, thereby keeping the clamping through hole 137 in a closed state (e.g., Figure 2 (as shown) and on / off status (as shown) Figure 3 Switching between (as shown) allows for the opening and closing of the clamping through hole 137 as needed.

[0086] Figure 4 This is a partial structural diagram of the connecting frame 120 in the endoscope device 100 provided in this embodiment. Please refer to... Figure 4 Optionally, the first clamping part 131 and the frame 121 are integrally molded by injection molding, and the connection between the first clamping part 131 and the frame 121 is reliable. It is understood that in some other embodiments, the first clamping part 131 and the frame 121 can also be connected in other ways as needed, such as bolt 1332 connection, etc.

[0087] Please refer to the reference. Figures 1-4 Specifically, the first clamping portion 131 forms a first recess 1313, the axis of which extends along the length direction of the frame 121. It should be noted that, as... Figures 1-4 As shown, the length direction of the frame 121 is the direction from the first connecting part 130 to the second connecting part 140. Meanwhile, the cross-section of the first recess 1313 in a preset plane is semi-circular. It should be noted that the preset plane is a plane perpendicular to the length direction of the frame 121. Along the radial direction of the first recess 1313, a first free end 1311 and a first connecting end 1312 are formed on both sides of the first recess 1313, respectively.

[0088] The second clamping portion 132 has a second recessed portion 1323 with a semi-circular cross-section, the axis of which extends along the length of the frame 121. Along the radial direction of the second recessed portion 1323, a second free end 1321 and a second connecting end 1322 are formed on both sides of the second recessed portion 1323, respectively. The first connecting end 1312 is connected to the second connecting end 1322, and a first opening 135 communicating with the clamping through hole 137 is formed between the first free end 1311 and the second free end 1321, so that the fixed end 113 can enter and exit the clamping through hole 137 through the first opening 135.

[0089] The second connecting end 1322 is rotatably connected to the first connecting end 1312 via a rotating shaft, which is the first rotating shaft 1361. The axis of the first rotating shaft 1361 extends along the length of the frame 121. When the second clamping part 132 is rotated towards the first clamping part 131 until the first free end 1311 and the second free end 1321 abut against each other (e.g., Figure 2As shown, the second recess 1323 is positioned opposite to the first recess 1313, thereby forming a circumferentially closed, through-hole 137 between the first recess 1313 and the second recess 1323. The fixed end 113 is fixed within the through-hole 137 by the combined action of the first clamping part 131 and the second clamping part 132. When the second clamping part 132 is rotated away from the first clamping part 131, the first free end 1311 separates from the second free end 1321, thereby forming a first opening 135 between the first free end 1311 and the second free end 1321, connecting the through-hole 137. The fixed end 113 can then enter and exit the through-hole 137 through the first opening 135.

[0090] Furthermore, the first connecting portion 130 also includes a first elastic pad 1315 and a second elastic pad 1325. The first clamping portion 131 has a first inner wall corresponding to the first recess 1313, and the first elastic pad 1315 is disposed on the first inner wall. The second clamping portion 132 has a second inner wall corresponding to the second recess 1323, and the second elastic pad 1325 is disposed on the second inner wall. When the first recess 1313 and the second recess 1323 are disposed opposite each other, the first elastic pad 1315 and the second elastic pad 1325 are opposite each other and form a clamping through hole 137. When the fixed end 113 is clamped and fixed in the clamping through hole 137, the first elastic pad 1315 and the second elastic pad 1325 act simultaneously on both sides of the fixed end 113. The first elastic pad 1315 and the second elastic pad 1325 are compressed by the fixed end 113 and undergo elastic deformation, thereby clamping the fixed end 113 by the elastic force of the first elastic pad 1315 and the second elastic pad 1325. The fixing reliability is high, and the damage to the fixed end 113 by the clamping force can be reduced.

[0091] Please continue to refer to the reference. Figures 1-4 The fixed end 113 of the endoscope body 110 is a frustum-shaped cone with its radial dimension gradually decreasing in the direction away from the operating part 111. The clamping through hole 137 is a conical hole adapted to the fixed end 113, so that the clamping effect of the first connecting part 130 on the fixed end 113 is better. Specifically, the first inner wall is semi-conical, that is, the first inner wall is the shape of one half of the periphery of the frustum-shaped cone after being divided into two halves along the generatrix. The second inner wall is semi-conical. When the first free end 1311 and the second free end 1321 abut against each other, and the first recess 1313 and the second recess 1323 are arranged opposite each other, the first inner wall and the second inner wall are spliced ​​to form a frustum-shaped hole. The first elastic pad 1315 is a semi-conical shape adapted to the first inner wall, and the second elastic pad 1325 is a semi-conical shape adapted to the second inner wall. Therefore, the clamping through hole 137 formed by the first elastic pad 1315 and the second elastic pad 1325 is conical.

[0092] It should be noted that in this embodiment, the first inner wall, the second inner wall, the first elastic pad 1315, and the second elastic pad 1325 are all semi-conical, thus making the hole formed by the first inner wall and the second inner wall conical, and the clamping through hole 137 formed by the first elastic pad 1315 and the second elastic pad 1325 also conical. It can be understood that in some other embodiments of this application, only the wall surfaces of the first elastic pad 1315 and the second elastic pad 1325 corresponding to the clamping through hole 137 can be set as semi-conical, as long as the formed clamping through hole 137 is conical. For example, the first inner wall and the second inner wall can both be set as semi-cylindrical surfaces, and the outer walls of the first elastic pad 1315 and the second elastic pad 1325 can be set as semi-cylindrical surfaces adapted to the first inner wall and the second inner wall, respectively.

[0093] Furthermore, along the length of the frame 121, the radial dimension of the clamping through hole 137 gradually decreases in the direction away from the second connecting portion 140. Therefore, when the fixed end 113 of the endoscope body 110 is clamped and fixed within the clamping through hole 137, the operating part 111 of the endoscope body 110 is located on the side of the clamping through hole 137 closer to the second connecting portion 140. In other words, the operating part 111 is located between the first connecting portion 130 and the second connecting portion 140. By placing the operating part 111 between the first connecting portion 130 and the second connecting portion 140, the connection reliability of the endoscope body 110 is improved, thereby helping to ensure ease of operation during use.

[0094] Please refer to the reference again. Figure 2 and Figure 3 In this embodiment, the first connecting portion 130 further includes a locking structure 133. The locking structure 133 is connected to both the first free end 1311 and the second free end 1321, thereby fixing the first clamping portion 131 and the second clamping portion 132 relative to each other, so that the clamping through hole 137 remains closed and the first opening 135 is prevented from opening during use.

[0095] The locking structure 133 includes a first locking part and a second locking part. The first locking part is disposed at the first free end 1311 and the second locking part is disposed at the second free end 1321. When the first locking part and the second locking part are connected, the first clamping part 131 and the second clamping part 132 are fixed relative to each other so that the clamping through hole 137 is in a closed state.

[0096] Specifically, the first locking part is provided with a limiting surface 1333, which is the wall surface behind the first free end 1311. That is, when the clamping through hole 137 is in the closed state, the second free end 1321 and the limiting surface 1333 are located on both sides of the first free end 1311, respectively. The second locking part includes a connecting rod 1334 and a limiting block 1335 connected to the connecting rod 1334. The end of the connecting rod 1334 away from the limiting block 1335 is rotatably connected to the second free end 1321 through a rotating shaft, which is the second rotating shaft 1362. When the second clamping part 132 rotates to the position where the clamping through hole 137 is closed, the operating connecting rod 1334 rotates relative to the second clamping part 132 to rotate the limiting block 1335 to the side of the first free end 1311 away from the second free end 1321. That is, at this time, the limiting block 1335 and the limiting surface 1333 are on the same side. Through the tight fit between the limiting block 1335 and the limiting surface 1333, the second clamping part 132 is prevented from rotating in the direction of opening the clamping through hole 137, thereby fixing the first clamping part 131 and the second clamping part 132 relative to each other.

[0097] Furthermore, the first locking part also has a notch 1339, which penetrates the limiting surface 1333 and is used to accommodate the connecting rod 1334. Specifically, the notch 1339 is formed at the end of the first free end 1311 away from the first recess 1313, and the notch 1339 has an opening on the end face of the first free end 1311 away from the first recess 1313, so that the connecting rod 1334 can enter the notch 1339 through the opening when it rotates, which helps to increase the contact area between the limiting block 1335 and the limiting surface 1333, and makes the locking effect of the locking structure 133 better.

[0098] Figure 5 This is a schematic diagram of the limiting block 1335 in the endoscope device 100 provided in this embodiment. Please refer to the diagram for further details. Figure 2 , Figure 3 and Figure 5 Furthermore, the limiting block 1335 and the connecting rod 1334 are rotatably connected via a pivot, which is a third pivot 1363. When the connecting rod 1334 is rotated so that the limiting block 1335 and the limiting surface 1333 are on the same side, the limiting block 1335 is pressed against the limiting surface 1333 by rotating the limiting block 1335, thereby locking the second clamping part 132 to the first clamping part 131, and the locking reliability is high.

[0099] Specifically, the limiting block 1335 includes a first wall surface 1336 and a second wall surface 1337 connected to each other, and the distance between the first wall surface 1336 and the axis of the third rotating shaft 1363 is less than the distance between the second wall surface 1337 and the axis of the third rotating shaft 1363. When the connecting rod 1334 is rotated to make the limiting block 1335 rotate to the same side as the limiting surface 1333, the first wall surface 1336 and the limiting surface 1333 are opposite to each other. At this time, there is a gap between the first wall surface 1336 and the limiting surface 1333. In other words, at this time, the distance between the first wall surface 1336 and the axis of the third rotating shaft 1363 is less than the distance between the limiting surface 1333 and the axis of the third rotating shaft 1363. Therefore, the limiting block 1335 can be rotated to the same side as the limiting surface 1333 more easily. Subsequently, the limiting block 1335 is rotated relative to the connecting rod 1334 to rotate to the locking position, thereby locking it to the limiting surface 1333. Specifically, the distance between the second wall surface 1337 and the axis of the third rotating shaft 1363 is slightly greater than or equal to the distance between the limiting surface 1333 and the axis of the third rotating shaft 1363. Therefore, when the second wall surface 1337 rotates to the position opposite to the limiting surface 1333, the limiting block 1335 presses tightly against the limiting surface 1333, and the limiting block 1335 is in the locking position, thereby locking the second clamping part 132 to the first clamping part 131.

[0100] Optionally, the first wall surface 1336 and the second wall surface 1337 are rounded to facilitate the rotation of the limiting block 1335 to place the limiting block 1335 in the locked position. Optionally, the limiting block 1335 also includes an operating handle 1338, which is a protrusion formed by the third wall surface of the limiting block 1335 protruding outward. The third wall surface is located on the side of the limiting block 1335 opposite to the first wall surface 1336, thus forming a whistle-shaped limiting block 1335.

[0101] It should be noted that the specific structure of the locking structure 133 is not limited here. It is understood that in other embodiments of this application, the locking structure 133 can also be specifically set according to the requirements.

[0102] As an example, Figure 6 The structure of the second type of endoscope device 100 provided in this embodiment is shown. The structure of the connecting frame 120 in the second type of endoscope device 100 is the same as the structure of the second connecting frame 120 provided in this embodiment. Therefore, accordingly, Figure 6 The structure of the second type of connecting bracket 120 provided in this embodiment is also shown in the diagram. Please refer to... Figure 6As shown, in this example, the locking structure 133 includes a nut 1331 and a bolt 1332. The bolt 1332 passes through both the first free end 1311 and the second free end 1321 and is screwed onto the nut 1331, thereby locking the second clamping part 132 onto the first clamping part 131, so that the first clamping part 131 and the second clamping part 132 are relatively fixed. When it is necessary to open the clamping through hole 137 to insert or remove the fixed end 113, the nut 1331 is unscrewed from the bolt 1332, and then the bolt 1332 is removed to rotate the second clamping part 132 to open the clamping through hole 137.

[0103] It should be noted that the specific structure of the first clamping part 131 and the second clamping part 132 is not limited here. It is understood that in other embodiments of this application, the specific structure of the first clamping part 131 and the second clamping part 132 can also be set according to the requirements.

[0104] As an example, Figure 7 The structure of the third type of endoscope device 100 provided in this embodiment is shown in a first view. The structure of the connecting frame 120 in the third type of endoscope device 100 is the same as the structure of the third type of connecting frame 120 provided in this embodiment. Therefore, accordingly, Figure 7 The structure of the third type of connector 120 provided in this embodiment is also shown. Figure 8 This is a structural schematic diagram of the third type of connecting bracket 120 provided in this embodiment. Please refer to the diagram for further details. Figure 7 and Figure 8 In this example, the first clamping part 131 and the second clamping part 132 are fixedly connected. The first clamping part 131 and / or the second clamping part 132 are elastic, thereby changing the size of the first opening 135 through the elastic deformation of the first clamping part 131 and / or the second clamping part 132, so that the fixed end 113 can enter and exit the clamping through hole 137 through the first opening 135. Moreover, the first free end 1311 and the second free end 1321 tend to move closer to each other, thereby clamping the fixed end 113 in the limiting through hole.

[0105] Specifically, the first clamping part 131 and the second clamping part 132 are integrally formed, that is, the first connecting end 1312 and the second connecting end 1322 are fixed together by integral molding. Both the first clamping part 131 and the second clamping part 132 are made of elastic plastic material, meaning both are elastic. Therefore, the size of the first opening 135 can be changed by the simultaneous elastic deformation of the first clamping part 131 and the second clamping part 132. It is understood that in some other embodiments, only one of the first clamping part 131 and the second clamping part 132 may be provided as needed, capable of changing the size of the first opening 135 through elastic deformation, allowing the fixed end 113 to smoothly enter and exit the clamping through hole 137 through the first opening 135.

[0106] The first free end 1311 and the second free end 1321 are spaced apart, so that the clamping through hole 137 formed by the first clamping part 131 and the second clamping part 132 has a notch in the circumferential direction, that is, the cross section of the clamping structure corresponding to the wall surface of the clamping through hole 137 is an arc. The notch 1339 formed by the first free end 1311 and the second free end 1321 is the first opening 135. That is to say, in the third type of connecting frame 120 shown in this application, the first opening 135 is always in the open state. Therefore, obviously, in order to prevent the fixed end 113 from coming out of the clamping through hole 137, when the clamping structure is in the natural state, the size of the first opening 135 should be smaller than the radial size of the corresponding position of the fixed end 113. That is, the size of the first opening 135 at the large end of the clamping through hole 137 is smaller than the radial size of the large end of the fixed end 113, and the size of the first opening 135 at the small end of the clamping through hole 137 is smaller than the radial size of the small end of the fixed end 113.

[0107] Since the first clamping part 131 and the second clamping part 132 are integrally formed, the wall surface of the first clamping part 131 corresponding to the clamping through hole 137 and the wall surface of the second clamping part 132 corresponding to the clamping through hole 137 are located on the same cylindrical surface. Optionally, the first elastic pad 1315 and the second elastic pad 1325 are integrally formed.

[0108] Please continue to refer to the reference. Figure 7 and Figure 8 The first clamping part 131 further includes a first guide part 1314 disposed at the first free end 1311, and the second clamping part 132 further includes a second guide part 1324 disposed at the second free end 1321. The first guide part 1314 and the second guide part 1324 are both located outside the clamping through hole 137 and extend in a direction away from the clamping through hole 137. Along the radially outward direction of the clamping through hole 137, the distance between the first guide portion 1314 and the second guide portion 1324 gradually increases; in other words, along the radially inward direction of the clamping through hole 137, the distance between the first guide portion 1314 and the second guide portion 1324 gradually decreases. Thus, the fixed end 113 is guided from the first opening 135 into the clamping through hole 137 by the first guide portion 1314 and the second guide portion 1324. Moreover, as the fixed end 113 moves towards the first opening 135 along the channel formed by the first guide portion 1314 and the second guide portion 1324, the mutual compression between the fixed end 113 and the first guide portion 1314 and the second guide portion 1324 causes the first free end 1311 and the second free end 1321 to tend to move away from each other, that is, the first opening 135 tends to increase in size.

[0109] It should be noted that, in the above description, this application provides three structures for the first connecting part 130. All three types of first connecting parts 130 are connected to the fixed end 113 by clamping to fix the endoscope body 110 to the connecting frame 120. It is understood that, in some other embodiments, the first connecting part 130 can also be connected to the fixed end 113 in other ways by setting it. For example, the first connecting part 130 can be set as a cable tie structure 134, and the fixed end 113 can be fixed to the connecting frame 120 by the cable tie 1341, thereby realizing the fixed connection between the endoscope body 110 and the connecting frame 120.

[0110] As an example, Figure 9 This embodiment illustrates the structure of the fourth type of connector 120. Figure 10 This embodiment illustrates the structure of the cable tie 1341 in the fourth type of connector 120 provided in this embodiment. Please refer to the reference. Figure 9 and Figure 10 The first connecting part 130 is a cable tie structure 134. Optionally, the cable tie structure 134 includes a cable tie 1341 and a first cable tie hole 1345 and a second cable tie hole 1346 opened in the frame 121. The first cable tie hole 1345 and the second cable tie hole 1346 are arranged at intervals relative to each other, and the two ends of the cable tie 1341 pass through the first cable tie hole 1345 and the second cable tie hole 1346 respectively, so that both ends of the cable tie 1341 are fixed to the frame 121, and the fixing end 113 is fixed between the cable tie 1341 and the frame 121.

[0111] Specifically, the first cable tie hole 1345 and the second cable tie hole 1346 are spaced apart along the width direction of the frame 121, and the two ends of the first cable tie hole 1345 respectively penetrate two adjacent walls of the frame 121, and the two ends of the second cable tie hole 1346 respectively penetrate two adjacent walls of the frame 121. The cable tie 1341 includes a strap body 1342 and a limiting protrusion 1344 disposed at one end of the strap body 1342 along its length direction. The size of the limiting protrusion 1344 is larger than the opening size of the first cable tie hole 1345. When the strap body 1342 passes through the first cable tie hole 1345, the first limiting block 1335 abuts against the wall of the frame 121 to prevent the strap body 1342 from coming out of the first cable tie hole 1345. Along the length of the belt body 1342, multiple locking teeth 1343 are provided on the belt body 1342. When the belt body 1342 passes through the second cable tie hole 1346, the belt body 1342 is fixed to the second cable tie hole 1346 by locking the locking teeth 1343 with the step structure formed at the opening of the second cable tie hole 1346.

[0112] Furthermore, the frame 121 is also provided with a recess located between the first cable tie hole 1345 and the second cable tie hole 1346, which is a third recess 128. Specifically, the frame 121 has a wall surface corresponding to the third recess 128, which is a semi-circular frustum extending along the length direction of the frame 121. Optionally, the connecting frame 120 also includes an elastic pad disposed in the third recess 128, which is a third elastic pad 1281.

[0113] In this embodiment, the first connecting part 130 is rotatably connected to the frame 121, thereby allowing adjustment of the relative angular position between the endoscope body 110 and the frame 121 according to usage requirements. The connecting frame 120 also includes a locking member 127, which is used to connect to both the first connecting part 130 and the frame 121 simultaneously, allowing the first connecting part 130 to switch between a locked state and a rotatable state. When the first connecting part 130 is in the locked state, it is fixed relative to the frame 121 to prevent changes in the position of the endoscope body 110 during use. When the first connecting part 130 is in the rotatable state, it can rotate relative to the frame 121 to adjust the relative angular position between the first connecting part 130 and the frame 121, thereby placing the endoscope body 110 in a convenient operating position to meet the operational needs of different doctors.

[0114] The structure in which the first connecting part 130 is rotatably connected to the frame 121 will now be described using the structure of the third type of endoscope device 100 provided in this embodiment. Figure 11 This is a schematic diagram of the third endoscopic device 100 provided in this embodiment from a second perspective. Figure 12 for Figure 11 A schematic diagram of the cross-sectional structure at point AA. Please refer to the diagram. Figure 11 and Figure 12 In this embodiment, the locking member 127 is a locking screw. A threaded hole is provided on the first connecting portion 130. The locking screw passes through the frame 121 and is screwed into the first connecting portion 130 through the threaded hole, thereby connecting the first connecting portion 130 to the frame 121. Since the first connecting portion 130 in the third type of endoscope device 100 provided in this embodiment is composed of an integrally formed first clamping portion 131 and a second clamping portion 132, and the threaded hole of the first connecting portion 130 is located in the middle of the first connecting portion 130, that is, the threaded hole is simultaneously opened in the first clamping portion 131 and the second clamping portion 132. In other words, in this example, the first clamping portion 131 and the second clamping portion 132 can be considered as simultaneously connected to the frame 121. It is understood that in some other embodiments, the threaded hole can also be opened on the side of the first connecting portion 130, that is, the threaded hole is located on the first clamping portion 131 or the second clamping portion 132.

[0115] When the locking screw is tightened, the first connecting part 130 is fixed relative to the frame 121 under the locking action of the locking screw, and the first connecting part 130 is in a locked state. When the locking screw is loosened, the first connecting part 130 is loose relative to the frame 121, and the first connecting part 130 is in a rotatable state, so that the relative angle position between the first connecting part 130 and the frame 121 can be adjusted as needed, thereby realizing the adjustment of the relative angle position between the endoscope body 110 and the frame 121. In other words, the relative angle position between the endoscope body 110 and the auxiliary medical device 200 can be adjusted.

[0116] Figure 13 This is a schematic diagram of the frame 121 in the endoscope device 100 provided in this embodiment. Please refer to the diagram for further details. Figure 4 and Figure 13 ,in Figure 13 The structure of the rear side of the frame 121 is shown. It should be noted that, in this embodiment, the side of the frame 121 where the first connecting part 130 and the second connecting part 140 are located is the front side of the frame 121 (e.g., Figure 4 As shown, the rear side of the frame 121 is the opposite side to the front side, that is, the rear side of the frame 121 is the side facing away from the first connecting part 130 and the second connecting part 140. In this embodiment, the rear side of the frame 121 has a wedge-shaped cavity, and therefore the frame 121 has an inclined wall corresponding to the cavity. A reinforcing rib 126 is provided in the cavity, and the front end of the reinforcing rib 126 is connected to the inclined wall. By setting the frame 121 in a wedge shape and adding the reinforcing rib 126, the strength of the frame 121 can be significantly improved.

[0117] It should be noted that in the various endoscope devices 100 described above in this embodiment, the frame 121 is a component integrally molded by injection molding. It is understood that in other embodiments, the structure of the frame 121 can also be set according to needs. For example, the frame 121 can be set as a telescopic structure, so that the distance between the first connecting part 130 and the second connecting part 140 can be adjusted to meet the usage needs of different doctors and make it more convenient to use.

[0118] As an example, Figure 14 This embodiment illustrates the structure of the fifth type of connector 120. Figure 15 This embodiment illustrates the structure of the first frame 121 in the fifth type of connecting frame 120. Figure 16 This illustration shows the structure of the second frame 121 in the fifth type of connecting frame 120 provided in this embodiment. Please refer to the reference. Figures 14-16In this embodiment, the frame 121 includes a first sub-frame 122 and a second sub-frame 125. A first connecting portion 130 is disposed on the first sub-frame 122, and a second connecting portion 140 is disposed on the second sub-frame 125. The first sub-frame 122 and the second sub-frame 125 are slidably coupled, thereby changing the distance between the first connecting portion 130 and the second connecting portion 140, and thus adjusting the distance between the endoscope body 110 and the auxiliary medical device 200, facilitating user operation.

[0119] Specifically, a sliding groove 1221 is provided on the first sub-frame 122, and the second sub-frame 125 is slidably disposed within the sliding groove 1221. The sliding groove 1221 extends along the length of the frame 121, thereby adjusting the distance between the first connecting portion 130 and the second connecting portion 140 by the relative sliding of the first sub-frame 122 and the second sub-frame 125 along the sliding groove 1221.

[0120] Please continue to refer to the reference. Figures 14-16 The first sub-frame 122 has a first connecting hole 1222 communicating with the slide groove 1221, and the second sub-frame 125 has a second connecting hole 1251. The connecting frame 120 also includes a fixing member 123, which passes through the first connecting hole 1222 and connects to the second connecting hole 1251 of the second sub-frame 125 in the slide groove 1221. That is, the fixing member 123 cooperates with both the first connecting hole 1222 and the second connecting hole 1251, thereby fixing the first sub-frame 122 and the second sub-frame 125 relatively. There are multiple second connecting holes 1251, which are spaced apart along the length of the frame 121. By cooperating with different second connecting holes 1251, the fixing member 123 can fix the second sub-frame 125 at different positions on the first sub-frame 122, thereby adjusting the distance between the first connecting part 130 and the second connecting part 140. Understandably, in some other embodiments, the number of first connecting holes 1222 can be set to multiple, depending on the needs. Multiple first connecting holes 1222 are spaced apart along the length of the frame 121. The distance between the first connecting part 130 and the second connecting part 140 can be adjusted by the cooperation of the fastener 123 with different first connecting holes 1222. Alternatively, the number of both the first connecting holes 1222 and the second connecting holes 1251 can be set to multiple.

[0121] Optionally, there is one first connecting hole 1222, and the first connecting hole 1222 is a strip-shaped hole extending along the length direction of the frame 121, that is, the first connecting hole 1222 is a strip-shaped hole extending along the direction from the first connecting part 130 to the second connecting part 140. Therefore, when it is necessary to adjust the distance between the first connecting part 130 and the second connecting part 140, loosening the fixing member 123 will allow the second sub-frame 125 to slide relative to the first sub-frame 122, and at the same time, stepless adjustment of the distance between the first connecting part 130 and the second connecting part 140 can be achieved, with higher adjustment precision and easier operation by the user. Optionally, there are two fixing members 123, and the two fixing members 123 respectively cooperate with the two second connecting holes 1251.

[0122] It should be noted that the structure for making the distance between the first connecting part 130 and the second connecting part 140 adjustable is not limited here. It is understood that in some other embodiments, the structure of the connecting frame 120 can also be specifically set according to the requirements.

[0123] As an example, Figure 17 The structure of the sixth type of connector 120 provided in this embodiment is shown from a first-view perspective. Figure 18 This embodiment illustrates the structure of the first sub-frame 122 in the sixth type of connecting frame 120. Figure 19 The structure of the sixth type of connector 120 provided in this embodiment is shown from a second perspective. Figure 20 It shows Figure 19 Cross-sectional structure at point BB. Figure 21 It shows Figure 19 Cross-sectional structure at point CC. Please refer to the reference section. Figures 17-21 In this embodiment, the first sub-frame 122 is provided with a second opening 1223 communicating with the slide groove 1221. The frame 121 also includes a clamping member 124, which is rotatably disposed in the second opening 1223. By rotating the clamping member 124, the second sub-frame 125 is pressed into the slide groove 1221, or the second sub-frame 125 is released, so that the second sub-frame 125 can slide relative to the first sub-frame 122.

[0124] Specifically, the structure of the clamping element 124 is basically the same as the structure of the aforementioned limiting block 1335, such as... Figure 20 As shown, when the clamping member 124 presses against the second sub-frame 125, the second sub-frame 125 is pressed into the slide groove 1221 by the clamping member 124, so that the second sub-frame 125 is fixed relative to the first sub-frame 122. Figure 21As shown, when the clamping member 124 releases the second sub-frame 125, the clamping member 124 and the second sub-frame 125 are not in contact. In other words, at this time, the closest part between the clamping member 124 and the second sub-frame 125 still has a gap with the second sub-frame 125. This allows the second sub-frame 125 to slide relative to the first sub-frame 122, thereby adjusting the distance between the first connecting part 130 and the second connecting part 140.

[0125] Optionally, the third opening 1491 is a strip-shaped hole formed at the upper end of the first sub-frame 122, extending along the length of the frame 121. Two clamping members 124 are provided, spaced apart along the extension direction of the strip-shaped hole. Simultaneous clamping by the two clamping members 124 helps ensure a proper clamping effect. It is understood that in some other embodiments, the number of clamping members 124 may be one or three, as long as the clamping requirements are met.

[0126] Figure 22 This is a schematic diagram of the second connecting part 140 in the endoscope device 100 provided in this embodiment from a first viewing angle. Figure 23 This is a schematic diagram of the structure of the second connecting part 140 in the endoscope device 100 provided in this embodiment from a second viewing angle. Figure 24 This is a schematic diagram of the connection structure between the second connecting part 140 and the auxiliary medical device 200 in the endoscope system 10 provided in this embodiment. Figure 25 This is a schematic diagram of the auxiliary medical device 200 in the endoscope system 10 provided in this embodiment. Please refer to the diagram. Figures 22-25 In this embodiment, the second connecting part 140 is a slot 149 provided on the frame 121, and the auxiliary medical device 200 has a snap-fit ​​part 210 that cooperates with the slot 149. The connection between the second connecting part 140 and the auxiliary medical device 200 is realized through the snap-fit ​​part 210 and the slot 149, and the connection is convenient and quick.

[0127] Optionally, the second connecting portion 140 includes a first protrusion 141 and a second protrusion 142 spaced apart from each other, the first protrusion 141 and the second protrusion 142 being spaced apart along the length direction of the frame 121, thereby forming a groove 149 between the first protrusion 141 and the second protrusion 142. It is understood that in some other embodiments, the groove 149 can also be machined directly on the frame 121 as needed. Optionally, the first protrusion 141 and the second protrusion 142 are integrally formed with the frame 121 by injection molding.

[0128] Specifically, the cross-sections of the first protrusion 141 and the second protrusion 142 are L-shaped. That is, the first protrusion 141 has a first limiting part 1411 that is spaced apart from the front side wall of the frame 121, and the second protrusion 142 has a second limiting part 1421 that is spaced apart from the front side wall of the frame 121. The first limiting part 1411 and the second limiting part 1421 are spaced apart, thereby forming an opening between the first limiting part 1411 and the second limiting part 1421. This opening is the third opening 1491, through which the slot 149 is connected to the outside. When the locking part 210 of the auxiliary medical device 200 is inserted into the slot 149, the part of the locking part 210 that is connected to the body of the auxiliary medical device 200 passes through the third opening 1491 to connect with the body part located outside the slot 149. The latching part 210 includes a first latching protrusion 211 and a second latching protrusion 212 disposed opposite to each other. When the latching part 210 is latched into the slot 149, the first latching protrusion 211 and the second latching protrusion 212 abut against the first limiting part 1411 and the second limiting part 1421 respectively to limit the latching part 210 from the third opening 1491.

[0129] The first protrusion 141 and the second protrusion 142 are arranged parallel to each other, meaning that the size of the groove 149 formed between the first protrusion 141 and the second protrusion 142 is equal everywhere in the extending direction. To prevent the engaging part 210 from sliding out from the lower side of the groove 149, the second connecting part 140 further includes a limiting protrusion 143 disposed between the first protrusion 141 and the second protrusion 142. The two ends of the limiting protrusion 143 are respectively connected to the lower ends of the first protrusion 141 and the second protrusion 142, thereby closing the opening on the lower side of the groove 149. It can be understood that in some other embodiments, it can also be configured such that the distance between the first protrusion 141 and the second protrusion 142 gradually approaches from top to bottom. In this way, the width of the lower end of the groove 149 is smaller than the width of the upper end, thereby preventing the engaging part 210, which is engaged in the groove 149 from the upper side, from sliding out from the lower side of the groove 149.

[0130] Furthermore, the second connecting portion 140 also includes a third protrusion 144 and a fourth protrusion 145 disposed between the first protrusion 141 and the second protrusion 142. The third protrusion 144 and the fourth protrusion 145 are strip-shaped protrusions formed by protruding forward from the front sidewall of the frame 121. The front end face of the third protrusion 144 and the front end face of the fourth protrusion 145 are located in the same plane, which is the first plane 146. The rear sidewall of the first limiting portion 1411 and the rear sidewall of the second limiting portion 1421 are located in the same plane, which is the second plane 147. The first plane 146 and the second plane 147 are relatively parallel and spaced apart. When the snap-fit ​​portion 210 is snapped into the slot 149, the snap-fit ​​portion 210 is clamped between the first plane 146 and the second plane 147, thereby clamping and fixing the auxiliary medical device 200 in the slot 149, with high fixation reliability.

[0131] Furthermore, both the third protrusion 144 and the fourth protrusion 145 have guide surfaces 148 at their upper ends. Along the top-to-bottom direction, the distance between the guide surface 148 and the front end face of the frame 121 gradually increases, that is, the distance between the guide surface 148 and the first plane 146 gradually decreases. Optionally, the guide surface 148 is an inclined surface.

[0132] The working principle of the endoscope device 100 provided in this embodiment is as follows:

[0133] The first connecting part 130 of the connecting frame 120 of the endoscope device 100 is fixedly connected to the fixed end 113 of the endoscope body 110, thereby fixing the endoscope body 110 to the connecting frame 120. Then, the auxiliary medical device 200 is snapped and fixed to the connecting frame 120 through the second connecting part 140, thereby realizing the connection between the endoscope body 110 and the auxiliary medical device 200. This makes it convenient for the user to operate both the endoscope body 110 and the auxiliary medical device 200 with one hand. When different users use the endoscope device 100, the angle of the first connecting part 130 and the distance between the first connecting part 130 and the second connecting part 140 can be adjusted to meet the usage needs, resulting in higher user comfort and more convenient operation.
