[0042] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0045] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] The present invention aims to provide an elevator and a tip adapted for use in an endoscope body having a thinner radial dimension, such as a bronchoscope, which typically has a radial dimension of 6-7 mm.

[0047] This embodiment provides an endoscope lifting device, see Figure 1As shown in Figure 6, it includes a support 1, a lifting clamp seat 2 and a traction member 3. The lifting clamp seat 2 is suitable for abutting against an instrument. The traction member 3 is arranged in the support 1. The support 1 is provided with a first channel 5. The first channel 5 is suitable for the instrument to enter or exit. The distal end of the support 1 is provided with a lifting avoidance position 11. The first channel 5 and the lifting avoidance position 11 are connected. The lifting clamp seat 2 is configured to be slidable with the support 1. The traction member 3 and the lifting clamp seat 2 are fixedly connected. The traction member 3 is suitable for pulling the lifting clamp seat 2 to slide relative to the support 1 under the action of a driving force to adjust the distance between the lifting clamp seat 2 and the lifting avoidance position 11, so that the lifting clamp seat 2 can abut against the instrument and move toward the lifting avoidance position 11, or make the lifting clamp seat 2 move away from the lifting avoidance position 11. When the lifting clamp seat 2 moves away from the lifting avoidance position 11, the distal end of the instrument has the ability to reset itself, and the instrument can gradually recover from a bent posture to a straight posture.

[0048] The endoscope forceps lifting device provided in this embodiment acts on the traction member 3 through the driving force, so that the traction member 3 drives the forceps lifting seat 2 to slide relative to the support 1, and the forceps lifting seat 2 contacts the instrument and acts to move the distal end of the instrument toward the lifting avoidance position 11.

[0049] The proximal end of the traction member 3 is connected to the handle of the proximal operating part, so that the traction member 3 is driven to move linearly through the handle of the proximal operating part, thereby driving the lifting clamp seat 2 to slide relative to the support 1. In a specific embodiment, see Figure 5 , the traction member 3 is set to be a steel wire rope.

[0050] The endoscope forceps lifter provided in this embodiment realizes the lifting operation of the instrument through the sliding movement of the forceps lifting seat 2. Compared with the rotational drive method, when the instrument is extended to the same length at the far end of the support 1, this embodiment is easier to control for a small lifting and bending angle; when the forceps lifting seat 2 and the support 1 slide relative to each other, the node of the bending and rotation of the instrument is also changing; the image information of the operating position can be fed back through the configured endoscopic image device, so that the user can know the bending working condition of the instrument. When the extended length of the instrument is long, the desired lifting height is achieved by the shorter sliding of the forceps lifting seat 2. When the extended length of the instrument is short, the desired lifting height is achieved by the longer sliding of the forceps lifting seat 2. Adjusting the lifting height of the far end of the operating instrument is flexible and convenient.

[0051] In a specific embodiment, the bending angle of the instrument under the sliding contact of the lifting forceps seat 2 is set to 1-12 degrees, preferably, the bending angle is 5 degrees, 8 degrees, 10 degrees, etc.

[0052] In some embodiments, see Figure 6The lifting clamp seat 2 includes a sliding portion 21 and a supporting portion 22 that are fixedly connected. The sliding portion 21 is slidably arranged in the support 1. The traction member 3 is fixedly connected to the sliding portion 21. At least part of the support 1 and the supporting portion 22 are slidably arranged. The support 1 plays a supporting and guiding role for the sliding portion 21 and the supporting portion 22, respectively, to enhance the movement accuracy of the lifting clamp seat 2.

[0053] In some embodiments, see Figure 2 The support 1 is provided with a sliding avoidance position 12, and the sliding portion 21 is installed on the sliding avoidance position 12. The sliding avoidance position 12 is connected to the lifting avoidance position 11 to configure a space for the lifting clamp seat 2 to abut against the working device and move toward the lifting avoidance position 11. The sliding avoidance position 12 can be set as a through-slot structure at the far end of the support 1; during actual assembly, the lifting clamp seat 2 is first slidably installed into the through-slot structure, and then the restraining member 4 is installed on the support 1. The restraining member 4 penetrates the arrangement of the lifting clamp seat 2 to restrain it.

[0054] In order to control the sliding stroke of the lifting clamp seat 2, the structure is strengthened to be stable and compact; as an exemplary embodiment, see Figure 2 and Figure 5 The endoscope forceps lifting device further includes a restraining member 4, which is mounted within the support 1 and adapted to abut against the limit-limiting forceps lifting base 2 to configure a first limit position and a second limit position for the forceps lifting base 2 to slide relative to the support 1. The first limit position is located proximal to the second limit position. The restraining member 4 constrains the sliding travel of the forceps lifting base 2 relative to the support 1, limiting the limit position of the sliding motion of the forceps lifting base 2 and preventing the risk of the forceps lifting base 2 slipping, falling out, and so on.

[0055] In some embodiments, see Figure 4 and Figure 6 A limiting groove 211 is constructed on the sliding portion 21, and the restraining member 4 is passed through the limiting groove 211. The extension direction of the limiting groove 211 is parallel to the direction of relative sliding between the lifting clamp seat 2 and the support 1. The restraining member 4 is abutted at both ends of the limiting groove 211 along its extension direction to configure the first limit position and the second limit position.

[0056] The limiting groove 211 is set as a closed groove; in a specific embodiment, the limiting groove 211 is set as a long waist groove, the restraint 4 is set as a positioning rod, the positioning rod and the long waist groove are abutted to guide the forward and backward sliding of the lifting clamp seat 2, and the positioning rod limits the end of the long waist groove to limit the extreme position of the movement of the lifting clamp seat 2, and the lifting clamp is stable and reliable to use.

[0057] In some embodiments, see Figure 3The first channel 5 includes a straight section 51 and a lifting section 52. The extension direction of the lifting section 52 is inclined relative to the extension direction of the straight section 51. At the first extreme position, the support portion 22 can overlap and intervene in the extension direction of the lifting section 52. At the second extreme position, the support portion 22 can withdraw from overlapping and intervening in the extension direction of the lifting section 52. When the endoscope is initially loaded with instruments, the lifting clamp seat 2 is placed in the second extreme position to avoid affecting the extension of the instruments. The instruments are inserted into the straight section 51 and then pass through the straight section 51, and can be directly extended to the outside of the distal end of the endoscope. When the bending angle of the instrument needs to be adjusted, the traction member 3 is driven to drive the lifting clamp seat 2 to move backward, away from the second extreme position.

[0058] In this embodiment, see Figure 4 A guide groove 221 suitable for slidingly abutting the instrument is constructed on the side of the support portion 22 facing the lifting avoidance position 11; in a specific embodiment, the guide groove 221 is configured as a concave limiting structure with an inclined curved surface, for example, the guide groove 221 can be configured as a shovel-shaped structure; when the guide groove 221 contacts the instrument, the instrument part in the lifting section 52 is tilted and guided along the guide groove 221, and the bending adjustment process is passively implemented.

[0059] In some embodiments, a prismatic protrusion is provided on the contact surface of the support 1 facing the support portion 22. The prismatic protrusion is used to reduce the sliding contact area between the two while ensuring that the support 1 plays a role of sliding guide support for the support portion 22, thereby reducing movement resistance and preventing jamming or blocking; the prismatic protrusion can be extended along the sliding direction of the lifting clamp seat 2.

[0060] In order to improve the sealing performance of the endoscope lifting device and prevent the body fluid in the human body cavity from adhering to the traction member 3 and spreading along with the traction member 3, the endoscope lifting device also includes a sealing component, which can seal the traction member 3 to prevent the body fluid from directly entering the channel where the traction member 3 is located; Figure 5 and Figure 6 The sealing component includes a transition piece 61, a limit piece 62 and a seal 63; the transition piece 61 is sleeved and fixed on the outside of the traction piece 3, the limit piece 62 is installed in the support 1, and the seal 63 is abutted against the limit piece 62 in the direction of the lifting clamp seat 2, and at least part of the transition piece 61 is slidably sleeved in the limit piece 62 and the seal 63. A space for the transition piece 61 to slide is provided in the limit piece 62. The seal 63 seals the distal port of the limit piece 62 to prevent the body fluids contacted by the transition piece 61 from entering the limit piece 62 and contacting the traction piece 3 in the limit piece 62 when the lifting clamp seat 2 slides. In this embodiment, an outer barrier of the traction piece 3 is established by the transition piece 61, the limit piece 62 and the seal 63 to prevent the traction piece 3 from contacting the body fluids, thereby improving the sealing ability of the lifting clamp and helping to reduce the processing volume of subsequent cleaning.

[0061] In a specific embodiment, the transition piece 61 and the limiting piece 62 are arranged in a sleeve structure, and the sealing piece 63 is arranged as a ring-shaped soft rubber sealing ring; the limiting piece 62 functions to fix and limit the sealing piece 63, so that the sealing piece 63 is kept in an effective sealing working position, and the body fluid is prevented from entering the limiting piece 62 and adhering to the traction piece 3.

[0062] In a specific embodiment, referring to Figures 4 to 6 , the lifting forceps seat 2 is provided with a connecting hole 212, the transition piece 61 is fixedly combined into the connecting hole 212, and the traction piece 3 is arranged in the transition piece 61; the distal end of the traction piece 3 is fixedly connected with the inner wall surface of the connecting hole 212, and the traction piece 3, the transition piece 61 and the lifting forceps seat 2 can be fixed as a whole by welding, gluing or other fixing modes; when the traction piece 3 is driven to move by an external force, the traction piece 3 drives the transition piece 61 and the lifting forceps seat 2 to synchronously slide.

[0063] In some embodiments, referring to Figure 5 , the sealing component further comprises a sleeve piece 64, which is detachably connected to one end of the limiting piece 62 away from the sealing piece 63, and the traction piece 3 is arranged to slide through the limiting piece 62 and the sleeve piece 64; the sleeve piece 64 can be fixedly connected with the limiting piece 62, the limiting piece 62 is fixedly arranged in the support 1, the sleeve piece 64 is arranged in the same axial extension direction as the front and back directions of the sliding of the lifting forceps seat 2, the sleeve piece 64 isolates the traction piece 3 from other components of the endoscope, and the sleeve piece 64 functions to guide the sliding of the traction piece 3.

[0064] The present application can actively configure the sliding displacement of the lifting forceps seat 2, adjust the relative distance between the lifting forceps seat 2 and the lifting avoiding position 11, and further realize the adjustment of the operation angle of the distal end of the instrument in the instrument channel. The structure of the lifting forceps seat 2 for lifting the instrument occupies a small space, and is compact, which can be adapted to be arranged in a mirror body with a smaller radial size, such as a bronchoscope, and well meets the use demand in a narrow space.

[0065] In the above description, the instrument is arranged as an instrument with a bending capability and rigidity at the distal end, such as an ultrasonic bronchoscope. In actual operation, the adjustment bending of the instrument and the action of the lifting forceps seat 2 can be independent, and are driven by different driving structures, respectively.

[0066] In some embodiments, the front and back sliding of the lifting forceps seat 2 can be adjusted and driven by corresponding counterclockwise and clockwise rotation of the handle of the proximal end operation part; the handle can be wound to drive the front and back sliding of the lifting forceps seat 2 through the linkage of the traction piece 3.

[0067] As a further implementation, the lockable mechanism can lock the forward and backward sliding of the lifting forceps holder 2 to position the bending angle and the lifting height of the endoscope relative to the instrument; for example, when the handle of the proximal operation part is rotated anticlockwise and clockwise to adjust the driving of the forward and backward sliding of the lifting forceps holder 2, the handle can be configured to press to lock the forward and backward sliding of the lifting forceps holder 2 and to press to unlock the forward and backward sliding of the lifting forceps holder 2.

[0068] The application also provides a head end comprising the endoscope lifting forceps described above.

[0069] Referring to Figure 1 and Figure 7 , the head end further comprises a detection component adapted for ultrasonic imaging, the detection component comprising a transducer seat 71 and an ultrasonic transducer 72, the transducer seat 71 being detachably coupled to the support 1, and the ultrasonic transducer 72 being mounted on the transducer seat 71. The ultrasonic transducer 72 is one of a convex array transducer, a linear transducer, a fan-shaped transducer, and a ring-shaped transducer.

[0070] Ultrasonic imaging is based on the principle of ultrasonic echo, which emits ultrasonic pulses to human tissues and then receives echoes from the interfaces of various layers of tissues for processing and display of ultrasonic information. Ultrasonic bronchoscopy is used for diagnosis of lung activity and lung cancer staging. In clinical applications, the forceps channel of the bronchoscope is a passive instrument such as a puncture needle or biopsy forceps, which provides a channel for biopsy or removal of tissues. The ultrasonic bronchoscope adds an ultrasonic examination component to the bronchoscope, which can provide real-time imaging of the puncture needle or biopsy forceps in ultrasonic imaging, thereby providing the doctor with a prediction of the puncture or clamping position before the puncture needle or biopsy forceps punctures or clamps, and providing ultrasonic auxiliary guidance to the doctor during puncture or clamping. The head end of the ultrasonic bronchoscope of the present embodiment adds a forceps lifter, which increases the activity range of the puncture needle or biopsy forceps, thereby increasing the examination range of the ultrasonic bronchoscope for biopsy or removal of bronchial tissues, which has practical value in clinical applications.

[0071] As a further implementation, the detection component further comprises a water bag (not shown in the figure) and a waterway structure; the water bag is arranged at the outer periphery of the ultrasonic transducer 72, and the waterway structure is mounted in the support 1, the water inlet side of the waterway structure being adapted to be communicatively arranged with an external water filling mechanism, and the water outlet side of the waterway structure being communicatively arranged with the water bag.

[0072] Referring to Figure 7The support 1 includes a second channel 73, which is separated from the first channel 5 and disconnected from the first channel 5. The waterway structure includes a first tube 74, a second tube 75, and a third channel 76. The third channel 76 is constructed within the transducer base 71. The first tube 74 passes through the second channel 73, and one end of the second tube 75 is fixedly sleeved within the first tube 74. The other end of the second tube 75 is fixedly inserted into the third channel 76, which is connected to the water bladder. The waterway structure is quick to assemble, which facilitates the manufacturing of the head end.

[0073] See also Figure 7 The transducer holder 71 is provided with a ridge 77 adapted to position and secure the water bladder. This ridge 77 not only provides a connection point for the bladder, but also optimizes the deformation of the bladder during filling, aligning it with the ultrasonic transducer 72 and accelerating the preparation of the test components.

[0074] See also Figure 1 The head end also includes auxiliary components, which include an illuminating element 81 and an objective lens 82 arranged on the support 1. The illuminating element 81 is suitable for imaging illumination, and the objective lens 82 is suitable for capturing external image information. The illuminating element 81 and the objective lens 82 are arranged at intervals.

[0075] The head end provided by the present invention has a compact structure and is suitable for an endoscope with a small radial size.

[0076] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
