Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to a combination of endoscope and forceps. Background Technology
[0002] In traditional techniques, endoscopes and foreign body forceps are kept separate and independent. In clinical practice, however, endoscopes and foreign body forceps are often used together to remove foreign objects from the body. The procedure is roughly as follows: The doctor first inserts the endoscope into the patient's body, using the lens and light source to observe the location and shape of the foreign object. Then, the doctor inserts the foreign body forceps into the instrument channel on the endoscope, allowing the forceps to proceed along the channel into the patient's body. The endoscope provides both the "channel" and the "visualization," enabling the forceps to accurately reach the target location. Guided by the endoscopic view, the doctor manipulates the handle of the forceps to grasp the foreign object. After securing the object, the forceps are slowly withdrawn along with the endoscope, ensuring the foreign object does not dislodge or damage the mucous membrane.
[0003] However, since the endoscope and foreign body forceps are independent structures, when using them together, the doctor must always operate the endoscope with one hand and the foreign body forceps with the other. This increases the doctor's workload, causes inconvenience, and hinders the doctor from completing the surgery efficiently and conveniently. Summary of the Invention
[0004] Therefore, it is necessary to provide a combined mirror-clamp instrument to address the above problems.
[0005] To address the above problems, this application provides the following technical solution:
[0006] A vibro-clamp compound instrument, the vibro-clamp compound instrument comprising:
[0007] An endoscope has an insertion part and an operating part. The insertion part has an instrument channel, and the operating part has an operating part housing and an angle control knob for controlling the bending of the insertion part. The angle control knob is rotatably connected to the operating part housing. A slide is provided on the inner wall of the operating part housing, and a fixing ring is provided on the outer wall of the operating part housing.
[0008] The foreign body forceps includes a forceps head, a forceps tube, a traction wire, and a control handle. The forceps tube passes through the instrument channel, and the traction wire passes through the forceps tube. Both ends of the traction wire are connected to the forceps head and the control handle, respectively. The control handle is partially confined within a slide rail to be integrated with the operating unit. The control handle is configured to slide relative to the slide rail. The control handle includes a movable ring. Both the movable ring and the forceps head are located outside the endoscope. The movable ring is configured to open and close relative to the operating unit housing. During the opening and closing process relative to the operating unit housing, the movable ring can drive the traction wire to move relative to the forceps tube.
[0009] The angle control knob, the fixed finger ring, and the movable finger ring are configured such that when the operator holds the vibratory forceps compound instrument with one hand, the thumb can reach and operate the angle control knob to rotate, the index finger can pass through the fixed finger ring, and the other three fingers can pass through the movable finger ring and operate the movable finger ring to slide relative to the slide rail and open and close relative to the operating part housing.
[0010] This endoscopic clamp device has at least the following beneficial effects:
[0011] When using this endoscopic forceps instrument, the surgeon can perform surgical procedures by holding the instrument with one hand as follows: pass the index finger through the fixed ring, pass the other three fingers through the movable ring, and press the thumb on the angle control knob or the outer shell of the operating part.
[0012] Specifically, surgical procedures can be performed while holding the endoscopic forceps instrument with one hand, as follows:
[0013] 1. Keep the other three fingers and index finger relatively still, and use your arm to move the endoscope and foreign body forceps in and out with one hand, so that the endoscope and foreign body forceps move in and out synchronously.
[0014] 2. Move your index finger away from the other three fingers, thus moving the fixed finger ring away from the movable finger ring. This causes the movable finger ring, traction wire, and pliers head to retract relative to the fixed finger ring, and the pliers head to gradually move closer to the insertion part. Conversely, move your index finger closer to the other three fingers, thus moving the fixed finger ring closer to the movable finger ring. This causes the movable finger ring, traction wire, and pliers head to advance relative to the fixed finger ring, and the pliers head to gradually move away from the insertion part. By moving the pliers head closer to or further away from the insertion part, the position of the pliers head relative to the insertion part can be changed.
[0015] 3. When the hand holding the vibratory forceps instrument is squeezed tightly, the movable ring closes relative to the outer shell of the operating part; when the hand holding the vibratory forceps instrument is opened, the movable ring opens relative to the outer shell of the operating part. By opening and closing the movable ring relative to the outer shell of the operating part, the traction wire can be moved relative to the forceps tube, thereby controlling the opening and closing of the forceps head.
[0016] 4. Press your thumb on the angle control knob and push it forward or backward to adjust the bending direction of the insertion part.
[0017] When there is no need to adjust the bending direction of the insertion part, the doctor presses his thumb on the outer shell of the operating part to avoid accidentally applying force to the angle control knob with his thumb, which could cause the bending direction of the insertion part to be changed unintentionally.
[0018] In summary, doctors only need one hand to operate the endoscopic forceps instrument, eliminating the need for both hands. This reduces the doctor's workload, makes the procedure easier, and helps doctors complete the surgery efficiently and conveniently.
[0019] In one embodiment, the angle control knob has a force-receiving part for the operator to apply force to. The force-receiving part is located on one side of the operating part housing and is disposed near the fixed finger ring and the movable finger ring. The fixed finger ring and the movable finger ring are located on the other side of the operating part housing, and the fixed finger ring is closer to the proximal end of the insertion part than the movable finger ring.
[0020] This design allows doctors to easily hold the endoscope and forceps combined instruments with one hand to perform surgical procedures.
[0021] In one embodiment, the control handle further includes a connecting seat, a connecting rod, a connecting rod, a movable receiving member, a fixed receiving member, a first receiving member, and a second receiving member; the connecting seat is fixedly connected to the movable ring, the connecting rod is rotatably connected to the connecting seat, and the connecting rod is fixedly connected to the connecting seat; the connecting seat, the connecting rod, and the connecting rod are arranged in a "Y" shape; both the movable receiving member and the fixed receiving member are confined within the slide rail and are configured to slide relative to the slide rail; the movable receiving member is fixedly connected to the connecting rod, and the fixed receiving member is fixedly connected to the connecting rod; in the movable ring... During the closing of the operating part housing, the portion of the movable receiving member away from the movable finger ring can abut against the wall of the slide; during the opening of the movable finger ring relative to the operating part housing, the portion of the movable receiving member near the movable finger ring can abut against the wall of the slide; the traction wire passes through the movable receiving member and the fixed receiving member, the first receiving member is relatively far from the proximal end of the insertion part and located within the movable receiving member, and the second receiving member is relatively close to the proximal end of the insertion part and located within the fixed receiving member; the first receiving member is fixed to the traction wire, and the second receiving member is fixed to the clamp tube.
[0022] With this configuration, the index finger moves away from or closer to the other three fingers, causing the movable ring to move relative to the fixed ring. The connecting seat, connecting rod, connecting rod, movable receiving part, fixed receiving part, first receiving part, second receiving part, traction wire, clamp tube, and clamp head move together with the movable ring, thus adjusting the position of the clamp head relative to the insertion part.
[0023] The single hand holding the vibratory forceps clamps tightens, causing the movable ring to close relative to the operating part housing. After the movable receiving part, away from the movable ring, abuts against the wall of the slide, the connecting rod rotates relative to the connecting seat. The movable receiving part moves away from the fixed receiving part, increasing the distance between the movable and fixed receiving parts. This increases the distance between the first and second receiving parts, causing the traction wire to move away from the forceps head relative to the forceps tube, thereby controlling the closing of the forceps head.
[0024] The single hand holding the vibratory forceps compound instrument is opened, thereby opening the movable finger ring relative to the operating part housing. After the movable receiving part near the movable finger ring abuts against the wall of the slide, the connecting rod rotates in the opposite direction relative to the connecting seat. The movable receiving part moves towards the fixed receiving part, and the distance between the movable receiving part and the fixed receiving part decreases. The distance between the first receiving part and the second receiving part also decreases, and the traction wire moves relative to the forceps tube in the direction closer to the forceps head, thereby controlling the opening of the forceps head.
[0025] In one embodiment, both the movable receiving member and the fixed receiving member are annular structures, and the axis of the movable receiving member, the axis of the fixed receiving member, and the axis of rotation of the connecting rod relative to the connecting seat are parallel to each other.
[0026] With this configuration, both the circumferential surfaces of the movable and fixed accommodating parts make line contact with the slide rail, resulting in low friction. This facilitates the movement of the movable and fixed accommodating parts within the slide rail.
[0027] In one embodiment, the movable receiving member is provided with a first arc-shaped hole, which is coaxial with the movable receiving member and extends through the movable receiving member along the extension direction of the traction wire; the fixed receiving member is provided with a second arc-shaped hole, which is coaxial with the fixed receiving member and extends through the fixed receiving member along the extension direction of the traction wire; the first arc-shaped hole, the second arc-shaped hole, and the traction wire are aligned; there are two of each of the first arc-shaped hole and the second arc-shaped hole, with the two first arc-shaped holes facing each other along the extension direction of the traction wire, and the two second arc-shaped holes facing each other along the extension direction of the traction wire.
[0028] With this configuration, during the opening and closing of the movable ring relative to the outer shell of the operating part, the first and second arc holes provide space for the traction wire to move, which can improve the stress state of the traction wire and facilitate the control of the traction wire.
[0029] In one embodiment, both the first accommodating member and the second accommodating member are spherical structures.
[0030] This design facilitates the movement of the first accommodating element within the movable accommodating element and the movement of the second accommodating element within the fixed accommodating element, thereby improving the stress state of the traction wire and making it easier to control the traction wire.
[0031] In one embodiment, the connecting seat is located on the outer side of the portion of the movable ring that is relatively close to the proximal end of the insertion portion.
[0032] This design facilitates the opening and closing of the movable ring relative to the operating part housing, and also facilitates the movement of the traction wire relative to the clamp tube during the opening and closing process of the movable ring relative to the operating part housing.
[0033] In one embodiment, the operating part housing includes a first half-shell and a second half-shell, the first half-shell and the second half-shell being detachably connected and jointly enclosing the slide rail; when the first half-shell and the second half-shell are separated, both the movable receiving member and the fixed receiving member can leave the slide rail, the first receiving member can leave the movable receiving member, and the second receiving member can leave the fixed receiving member.
[0034] With this setup, after disassembling the first and second halves of the shell, the movable ring, connecting seat, connecting rod, connecting rod, movable receiving part, and fixed receiving part can be removed. Then, the first receiving part can be removed from the movable receiving part, and the second receiving part can be removed from the fixed receiving part. After that, the traction wire and forceps head can be pulled out from the instrument channel. This allows for the separation of the foreign body forceps from the endoscope, facilitating the separate cleaning, disinfection, and sterilization of the foreign body forceps and the endoscope.
[0035] In one embodiment, the length direction of the slide is consistent with the length direction of the instrument channel.
[0036] This design facilitates the movement of the traction wire and clamp tube.
[0037] In one embodiment, the angle control knob has a force-receiving portion for the operator to apply force, and the outer shell portion of the operating portion protrudes towards the force-receiving portion to form a semi-circular thumb rest, the rotation axis of the angle control knob passing through the center of the thumb rest.
[0038] With this design, the rotation trajectory of the force-bearing part follows the outer contour of the thumb rest. When the thumb applies force to the force-bearing part to push the angle control knob to rotate, it can rest on the thumb rest, making it convenient for the thumb to apply force to the angle control knob and avoiding the situation where the thumb is suspended in the air and it is inconvenient to apply force to the angle control knob.

[0061] See Figures 1 to 14 This application provides a endoscopic forceps composite device, which includes an endoscope 1 and foreign body forceps 2.
[0062] See Figure 1 , Figure 2 , Figures 6 to 8 The endoscope 1 has an insertion part 12 and an operating part 11. The insertion part 12 has an instrument channel 121. The operating part 11 has an operating part housing 111 and an angle control knob 112 for controlling the bending of the insertion part 12. The angle control knob 112 is rotatably connected to the operating part housing 111. A slide rail 1113 is provided on the inner wall of the operating part housing 111, and a fixing ring 113 is provided on the outer wall of the operating part housing 111.
[0063] See Figures 1 to 4The foreign body forceps 2 includes a forceps head 21, a forceps tube 22, a traction wire 23, and a control handle 24. The forceps tube 22 passes through the instrument channel 121, and the traction wire 23 passes through the forceps tube 22. The two ends of the traction wire 23 are connected to the forceps head 21 and the control handle 24, respectively. The control handle 24 is partially confined within a slide rail 1113 to be integrated with the operating unit 11. The control handle 24 is configured to slide relative to the slide rail 1113. The control handle 24 includes a movable finger ring 241. Both the movable finger ring 241 and the forceps head 21 are located outside the endoscope 1. The movable finger ring 241 is configured to open and close relative to the operating unit housing 111. During the opening and closing process relative to the operating unit housing 111, the movable finger ring 241 can drive the traction wire 23 to move relative to the forceps tube 22.
[0064] See Figures 12 to 14 The angle control knob 112, fixed finger ring 113, and movable finger ring 241 are configured such that, when the operator holds the vitreoretinal forceps compound instrument with one hand, the thumb can reach and operate the angle control knob 112 to rotate, the index finger can pass through the fixed finger ring 113, and the other three fingers can pass through the movable finger ring 241 and operate the movable finger ring 241 to slide relative to the slide rail 1113 and to open and close relative to the operating part housing 111. Here, "the other three fingers" refers to the middle finger, ring finger, and little finger. For ease of description below, "the other three fingers" will be used consistently to refer to this combination of the middle finger, ring finger, and little finger.
[0065] When using this endoscopic forceps instrument, the surgeon can perform surgical operations by holding the instrument with one hand in the following manner: pass the index finger through the fixed finger ring 113, pass the other three fingers through the movable finger ring 241, and press the thumb on the angle control knob 112 or the operating unit housing 111.
[0066] Specifically, surgical procedures can be performed while holding the endoscopic forceps instrument with one hand, as follows:
[0067] 1. Keep the other three fingers and index finger relatively still, and use your arm to move the endoscope and forceps in one hand forward and backward, so that the endoscope 1 and the foreign body forceps 2 move forward and backward synchronously.
[0068] 2. Move your index finger away from the other three fingers, thereby moving the fixed finger ring 113 away from the movable finger ring 241. This causes the movable finger ring 241, the traction wire 23, and the pliers head 21 to retract relative to the fixed finger ring 113, and the pliers head 21 to gradually move closer to the insertion part 12. Move your index finger closer to the other three fingers, thereby moving the fixed finger ring 113 closer to the movable finger ring 241. This causes the movable finger ring 241, the traction wire 23, and the pliers head 21 to advance relative to the fixed finger ring 113, and the pliers head 21 to gradually move away from the insertion part 12. By moving the pliers head 21 closer to or further away from the insertion part 12, the position of the pliers head 21 relative to the insertion part 12 can be changed.
[0069] 3. Grip the vibratory forceps instrument firmly with one hand (e.g., ...). Figure 13 As shown), the movable ring 241 closes relative to the operating part housing 111; allowing the single hand holding the vibratory forceps compound instrument to open (as shown). Figure 12 As shown), the movable ring 241 opens relative to the operating part housing 111. By opening and closing the movable ring 241 relative to the operating part housing 111, the traction wire 23 can be moved relative to the clamp tube 22, thereby controlling the opening and closing of the clamp head 21.
[0070] 4. Press your thumb on the angle control knob 112 and push the angle control knob 112 forward or backward (e.g., Figure 13 and Figure 14 As shown), thereby adjusting the bending direction of the insertion part 12.
[0071] When it is not necessary to adjust the bending direction of the insertion part 12, the doctor presses his thumb on the operating part housing 111 (e.g., Figure 12 As shown), this avoids accidental changes in the bending direction of the insertion part 12 due to accidental force applied by the thumb to the angle control knob 112.
[0072] In summary, doctors only need one hand to operate the endoscopic forceps instrument, eliminating the need for both hands. This reduces the doctor's workload, makes the procedure easier, and helps doctors complete the surgery efficiently and conveniently.
[0073] In this application, the relevant technical features of controlling the opening and closing of the clamp head 21 by moving the traction wire 23 relative to the clamp tube 22, and the relevant technical features of controlling the bending of the insertion part 12 by the angle control knob 112 can all adopt existing technology, and will not be described in detail in this application.
[0074] See Figure 1 and Figure 2 The angle control knob 112 has a force-receiving part 1121 for the operator to apply force. The force-receiving part 1121 is located on one side of the operating part housing 111 and is close to the fixed finger ring 113 and the movable finger ring 241. The fixed finger ring 113 and the movable finger ring 241 are located on the other side of the operating part housing 111, and the fixed finger ring 113 is closer to the proximal end of the insertion part 12 than the movable finger ring 241. This allows the doctor to easily hold the endoscopic forceps compound instrument with one hand to perform surgical operations.
[0075] See Figure 2 , Figure 3 , Figures 9 to 11The control handle 24 also includes a connecting seat 242, a connecting rod 243, a connecting rod 244, a movable receiving member 245, a fixed receiving member 246, a first receiving member 247, and a second receiving member 248. The connecting seat 242 is fixedly connected to the movable ring 241, the connecting rod 243 is rotatably connected to the connecting seat 242, and the connecting rod 244 is fixedly connected to the connecting seat 242. The connecting seat 242, connecting rod 243, and connecting rod 244 are arranged in a "Y" shape. Both the movable receiving member 245 and the fixed receiving member 246 are confined within the slide rail 1113 and are configured to slide relative to the slide rail 1113. The movable receiving member 245 is fixedly connected to the connecting rod 243, and the fixed receiving member 246 is fixedly connected to the connecting rod 244. During the closing of the movable ring 241 relative to the operating part housing 111, the portion of the movable receiving member 245 away from the movable ring 241 can abut against the wall of the slide rail 1113. As the movable ring 241 opens relative to the operating part housing 111, the portion of the movable receiving member 245 near the movable ring 241 abuts against the wall of the slide rail 1113. The traction wire 23 passes through the movable receiving member 245 and the fixed receiving member 246. The first receiving member 247 is relatively far from the proximal end of the insertion part 12 and located within the movable receiving member 245, while the second receiving member 248 is relatively close to the proximal end of the insertion part 12 and located within the fixed receiving member 246. The first receiving member 247 is fixed to the traction wire 23, and the second receiving member 248 is fixed to the clamp tube 22.
[0076] By moving the index finger away from or closer to the other three fingers, the movable finger ring 241 moves relative to the fixed finger ring 113. The connecting seat 242, connecting rod 243, connecting rod 244, movable receiving member 245, fixed receiving member 246, first receiving member 247, second receiving member 248, traction wire 23, clamp tube 22 and clamp head 21 move together with the movable finger ring 241, thereby adjusting the position of the clamp head 21 relative to the insertion part 12.
[0077] Squeeze the vibratory forceps instrument with one hand (e.g.) Figure 13 As shown), the movable ring 241 closes relative to the operating part housing 111. After the portion of the movable receiving member 245 away from the movable ring 241 abuts against the wall of the slide rail 1113, the connecting rod 243 rotates relative to the connecting seat 242. The movable receiving member 245 moves away from the fixed receiving member 246, and the distance between the movable receiving member 245 and the fixed receiving member 246 increases. The distance between the first receiving member 247 and the second receiving member 248 also increases. The traction wire 23 moves away from the clamp head 21 relative to the clamp tube 22, thereby controlling the clamp head 21 to close.
[0078] Open the single hand holding the vibratory forceps instrument (e.g.) Figure 12As shown), the movable ring 241 opens relative to the operating part housing 111. After the portion of the movable receiving member 245 near the movable ring 241 abuts against the wall of the slide rail 1113, the connecting rod 243 rotates in the opposite direction relative to the connecting seat 242. The movable receiving member 245 moves towards the fixed receiving member 246, and the distance between the movable receiving member 245 and the fixed receiving member 246 decreases. The distance between the first receiving member 247 and the second receiving member 248 also decreases, and the traction wire 23 moves relative to the clamp tube 22 in the direction close to the clamp head 21, thereby controlling the clamp head 21 to open.
[0079] See Figure 9 and Figure 10 Both the movable receiving member 245 and the fixed receiving member 246 are annular structures. The axes of the movable receiving member 245, the fixed receiving member 246, and the rotation axis of the connecting rod 243 relative to the connecting seat 242 are parallel to each other. The circumferential surfaces of the movable receiving member 245 and the fixed receiving member 246 are in line contact with the slide rail 1113, resulting in low friction. This facilitates the movement of the movable receiving member 245 and the fixed receiving member 246 within the slide rail 1113.
[0080] See Figure 9 and Figure 10 The movable receiving member 245 has a first arc-shaped hole 2451, which is coaxial with the movable receiving member 245 and passes through the movable receiving member 245 along the extension direction of the traction wire 23. The fixed receiving member 246 has a second arc-shaped hole 2461, which is coaxial with the fixed receiving member 246 and passes through the fixed receiving member 246 along the extension direction of the traction wire 23. The first arc-shaped hole 2451, the second arc-shaped hole 2461, and the traction wire 23 are aligned. There are two of each type of arc-shaped hole 2451 and arc-shaped hole 2461. The two first arc-shaped holes 2451 are opposite each other along the extension direction of the traction wire 23, and the two second arc-shaped holes 2461 are opposite each other along the extension direction of the traction wire 23. During the opening and closing of the movable ring 241 relative to the operating part housing 111, the first arc hole 2451 and the second arc hole 2461 provide movement space for the traction wire 23, which can improve the stress state of the traction wire 23 and facilitate the operation of the traction wire 23.
[0081] See Figure 3 and Figure 11 Both the first receiving member 247 and the second receiving member 248 are spherical structures. This facilitates the movement of the first receiving member 247 within the movable receiving member 245 and the movement of the second receiving member 248 within the fixed receiving member 246, which helps to improve the stress state of the traction wire 23 and facilitates the control of the traction wire 23.
[0082] See Figure 3 and Figure 4The connecting seat 242 is located on the outer side of the portion of the movable ring 241 that is relatively close to the proximal end of the insertion part 12. This facilitates the opening and closing of the movable ring 241 relative to the operating part housing 111, and facilitates the movement of the traction wire 23 relative to the clamp tube 22 during the opening and closing of the movable ring 241 relative to the operating part housing 111.
[0083] Preferably, the movable ring 241, connecting seat 242, connecting rod 244, and fixed receiving member 246 are integrally formed. On the one hand, this can reduce manufacturing costs; on the other hand, it helps to ensure the structural strength of the control handle 24.
[0084] See Figure 1 and Figure 2 The operating unit housing 111 includes a first half-shell 1111 and a second half-shell 1112. The first half-shell 1111 and the second half-shell 1112 are detachably connected and together enclose a slide rail 1113. When the first half-shell 1111 and the second half-shell 1112 are separated, both the movable receiving member 245 and the fixed receiving member 246 can leave the slide rail 1113, the first received member 247 can leave the movable receiving member 245, and the second received member 248 can leave the fixed receiving member 246. After disassembling the first half-shell 1111 and the second half-shell 1112, the movable ring 241, connecting seat 242, connecting rod 243, connecting rod 244, movable receiving part 245 and fixed receiving part 246 can be removed. Then, the first receiving part 247 can be removed from the movable receiving part 245 and the second receiving part 248 can be removed from the fixed receiving part 246. Then, the traction wire 23 and the forceps head 21 can be pulled out from the instrument channel 121. This can separate the foreign body forceps 2 from the endoscope 1, making it convenient to clean, disinfect and sterilize the foreign body forceps 2 and the endoscope 1 separately.
[0085] For example, the first half-shell 1111 and the second half-shell 1112 are threaded together or snapped together.
[0086] See Figure 2 The length direction of the slide 1113 is consistent with the length direction of the instrument channel 121. This facilitates the movement of the traction wire 23 and the clamp tube 22.
[0087] See Figure 1 and Figure 2The angle control knob 112 has a force-receiving part 1121 for the operator to apply force. The outer shell 111 of the operating part protrudes towards the force-receiving part 1121 to form a semi-circular thumb rest 1114. The rotation axis of the angle control knob 112 passes through the center of the thumb rest 1114. In this way, the rotation trajectory of the force-receiving part 1121 follows the outer contour of the thumb rest 1114. When the thumb applies force to the force-receiving part 1121 to push the angle control knob 112 to rotate, it can rest on the thumb rest 1114, which makes it convenient for the thumb to apply force to the angle control knob 112 and avoids the situation where the thumb is suspended in the air and it is inconvenient to apply force to the angle control knob 112.
[0088] See Figures 1 to 3 The movable ring 241 has a scissor handle structure. This makes it easier for the doctor to hold the movable ring 241, thereby making it easier for the doctor to hold the endoscopic forceps compound instrument.
[0089] For example, the traction wire 23 is a steel wire.
[0090] See Figure 6 The operating unit housing 111 is provided with a clearance hole 1115, which communicates with the internal space of the slide rail 1113, and the control handle 24 passes through the clearance hole 1115.
[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0092] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the appended claims.
