DETAILED DESCRIPTION

[0039] The present application is further described in detail below in conjunction with the accompanying drawings.

[0040] Endoscopes can enter the body's internal cavities through the body's natural orifices or through small incisions made during surgery, and are currently widely used in the medical field. According to the different viewing angles, endoscopes can be divided into forward-looking (viewing angle 0°), oblique (viewing angle 0°-90°) and side-looking (viewing angle 90°).

[0041] The endoscope mainly includes an operating part and an insertion part, wherein the insertion part includes a head end at the distal end of the insertion part, and a camera is fixed in the head end. At the same time, a serpentine bending section is also provided at the distal end of the insertion part of some endoscopes. The operator can control the bending of the front end of the insertion part to adapt to the naturally curved cavity in the human body by controlling the bending of the serpentine bending section, so that the insertion part can penetrate into the cavity in the human body more smoothly.

[0042] At present, most endoscopes are designed with a fixed viewing angle. However, based on the observation needs of different parts, the actual application of the endoscope also requires the operator to adjust the direction of the endoscope by adjusting the angle of the front end of the insertion part. The operation is inconvenient and the observation range is easily limited, which makes it easier to produce blind spots.

[0043] An embodiment of the present application discloses an endoscope with an adjustable viewing direction head.

[0044] Reference Figure 1 and Figure 2, an endoscope with an adjustable viewing head end includes an operating part, an insertion part and a regulating component; wherein the insertion part is connected to the operating part, and the insertion part includes an insertion tube 8 and an adjustable viewing head end at the end of the insertion tube 8. At the same time, the regulating component includes a transmission member 9 and a control member, wherein the transmission member 9 is connected to the adjustable viewing head end for transmitting power, and the control member is provided in the operating part and is used to apply force to the transmission member 9 so that the transmission member 9 can move relatively. In this embodiment, the adjustable viewing head end includes a head end body 1, an adjustment seat 2 and a camera 3, wherein the adjustment seat 2 is rotatably connected to the head end body 1 so that the adjustment seat 2 can be angularly deflected relative to the head end body 1; specifically, a connecting part 4 for connecting the transmission member 9 is provided on the adjustment seat 2, and the adjustment seat 2 can be rotated relative to the head end body 1 after the connecting part 4 is subjected to force to achieve angular deflection. At the same time, the camera 3 is fixedly mounted on the adjustment seat 2 so that it can rotate relative to the head end body 1 as the adjustment seat 2 deflects, so that the viewing direction of the camera 3 can be adjusted by applying force to the connecting portion 4 on the adjustment seat 2 by the transmission member 9.

[0045] By using the above technology, the operator can apply force to the transmission member 9 via the control member on the operating part, and then use the transmission member 9 to apply force to the connecting part 4 to drive the camera 3 to rotate. Compared with an endoscope with a fixed viewing angle, this solution enables the operator to easily adjust the direction of the camera 3 in the endoscope, thereby expanding the observation range and reducing the blind spot of observation. In addition, compared with indirectly adjusting the viewing angle by adjusting the front end angle of the insertion part, this solution uses direct force to adjust the viewing angle of the camera 3. To a certain extent, it makes it more convenient for the operator to adjust the direction of the endoscope, and the change of the viewing angle of the camera 3 is achieved directly through the control member on the operating part, without the need for overly cumbersome training, which can reduce the operator's operating threshold to a certain extent.

[0046] It should be noted that the adjustment seat 2 rotates relative to the head end body 1 to achieve angle deflection after the connection part 4 is subjected to force. In this solution, it means that the adjustment seat 2 can achieve positive angle deflection and reverse angle deflection relative to the head end body 1. At the same time, the above technology can adjust the viewing angle of the camera 3 when necessary. In actual applications, the initial viewing angle of the camera 3 can be configured based on actual needs.

[0047] Reference Figure 3 In some specific embodiments, the initial viewing angle of the camera 3 can be configured to be 0°, that is, the camera 3 is initially forward-looking. The forward-looking camera 3 is convenient for the operator to observe the cavity during the process of pushing the insertion part, thereby facilitating the pushing of the insertion part of the endoscope into the cavity. Compared with the forward-looking endoscope with a fixed viewing angle, the scheme in the above embodiment can effectively expand the observation range and reduce the occurrence of blind spots. Figure 2In some other specific embodiments, the initial viewing angle of the camera 3 can also be configured as 90°, that is, the initial side-view type; compared with the side-view endoscope with a fixed viewing angle, the scheme in the aforementioned embodiment can adjust the direction of the camera 3 based on the need to push it into the cavity, so as to facilitate the pushing operation of the endoscope. In some other specific embodiments, the initial viewing angle of the camera 3 can also be configured as 0°-90°, that is, the initial oblique type; compared with the oblique endoscope with a fixed viewing angle, the scheme in the aforementioned embodiment can adjust the direction of the camera 3 based on the need to push it into the cavity, so as to facilitate the pushing operation of the endoscope, and can also adjust the direction of the camera 3 based on the need for side-view observation, so as to expand the observation range and reduce the occurrence of blind spots.

[0048] It is understandable that the head end body 1 usually has an instrument channel 17 along its own axis to allow the instrument to extend therefrom. Accordingly, the installation positions of the camera 3 and the adjustment seat 2 need to avoid the instrument channel 17 accordingly. In some specific embodiments, a notch 11 that is offset from the instrument channel 17 can be set at the front end of the head end body 1 to form a space for the adjustment seat 2 and the camera 3 to be installed and moved.

[0049] Reference Figure 1 and Figure 3 Further, in some specific embodiments, the transmission member 9 is configured as a transmission line extending along the axial direction of the insertion portion, and one end of the transmission line is connected to the connection portion 4, and the other end is connected to the control member. It should be noted that the transmission line, as the transmission member 9, transmits force to the connection portion 4 so that the adjustment seat 2 rotates relative to the head end body 1. In this solution, it is shown that the transmission line can transmit both the pulling force and the thrust force to the adjustment seat 2, that is, the transmission line actually selected has both a certain flexible bending performance and a certain axial rigidity so as to be able to transmit the axial thrust force.

[0050] Meanwhile, in some embodiments, the control member may adopt a manual control structure. Specifically, the control member may be a lever movably arranged on the operating part, and the transmission line is connected to the lever. The operator can drive the adjustment seat 2 and the camera 3 to rotate by shifting the lever and transmitting through the transmission line. In other embodiments, the control member may adopt an electric control structure. Specifically, the control member may include a motor, a circuit board for controlling the operation of the motor, and an operation button electrically connected to the circuit board. Accordingly, the output end of the motor is connected to the transmission line. The operator can drive the adjustment seat 2 and the camera 3 to rotate by pressing the operation button to drive the transmission line to move.

[0051] Reference Figure 2Furthermore, in some embodiments, the connection portion 4 is configured to be a connection pin rotatably connected to the adjustment seat 2, and the rotation axis of the connection pin relative to the adjustment seat 2 is parallel to the rotation axis of the adjustment seat 2 relative to the head end body 1. Therefore, when the transmission member 9 is used to transmit power to the connection pin to drive the adjustment seat 2 to rotate, the connection pin itself will also rotate adaptively based on the angle change of the adjustment seat 2, so as to reduce the situation where excessive bending occurs at the connection between the transmission member 9 and the connection pin, thereby affecting the connection stability.

[0052] Reference Figure 2 and Figure 3 Furthermore, in some embodiments, the head end with adjustable viewing direction further includes a sealing sleeve 5, one end of the sealing sleeve 5 is sealed and connected to the adjustment seat 2, and the other end is sealed and connected to the head end body 1, and at least part of the sealing sleeve 5 can bend and retract with the rotation of the adjustment seat 2. The sealing sleeve 5 forms a sealed channel between the head end body 1 and the adjustment seat 2, and the communication cable and the transmission member 9 can be arranged in the sealed channel to play a role of sealing and waterproofing; at the same time, when the adjustment seat 2 is rotated under force, the sealing sleeve 5 can also be adapted to retract to achieve deflection in the corresponding direction and angle. Specifically in this embodiment, the sealing sleeve 5 adopts a retractable thin-walled sleeve.

[0053] In a specific embodiment, in order to form a good seal between the sealing sleeve 5 and the adjustment seat 2, the end of the sealing sleeve 5 can be sleeved on the adjustment seat 2, and then the sealing sleeve 5 and the adjustment seat 2 are tightly sealed by bonding or welding.

[0054] Reference Figure 2 Furthermore, in some embodiments, the head end body 1 is axially extended with a connecting block 12, the connecting block 12 protrudes in the direction close to the adjustment seat 2, and the shape of the connecting block 12 is adapted to the port of the sealing sleeve 5, so that the sealing sleeve 5 can be used for the port of the sealing sleeve 5 to be sleeved, and then the sealing sleeve 5 and the connecting block 12 are stably connected by bonding or welding, so as to form a good seal between the two.

[0055] Reference Figure 2 Further, in some embodiments, the viewing direction adjustable head end body 1 further includes a flexible circuit board 6 in the sealing sleeve 5. Specifically, in combination with Figure 4, the flexible circuit board 6 is provided with an electrical connection part 614, a first connection part 624, a second connection part 634 and an extension connection part 4 in sequence; wherein the first connection part 624 and the second connection part 634 are arranged at intervals to form a movable section, and the first connection part 624 is fixedly connected to the adjustment seat 2, and the second connection part 634 is fixedly connected to the head end body 1, so that the movable section can be adaptively bent and adjusted during the rotation of the adjustment seat 2 relative to the head end body 1; and the first connection part 624 and the adjustment seat 2, and the second connection part 634 and the head end body 1 can be fixedly connected by bonding, clamping, etc. At the same time, the electrical connection part 614 is on the side of the first connection part 624 away from the second connection part 634, and the electrical connection part 614 is used to electrically connect with the camera 3; the extension connection part 4 is on the side of the second connection part 634 away from the second connection part 634, and the extension connection part 4 is used to connect the communication cable. This arrangement can effectively reduce the situation where the camera 3 is unstable in communication connection during the rotation of the adjustment base 2, thereby affecting normal use.

[0056] Combination Figure 5 Furthermore, the head end body 1 is provided with a communication channel 13, and the communication channel 13 is used for the flexible circuit board 6 and / or the communication cable to pass through; at the same time, the head end body 1 can also be provided with a transmission channel 14 for the transmission member 9 to pass through. Moreover, in the embodiment provided with the sealing sleeve 5, the openings of the communication channel 13 and the transmission channel 14 close to the adjustment seat 2 are both covered by the sealing sleeve 5. In addition, if in the embodiment provided with the connection block 12, the communication channel 13 and the transmission channel 14 are axially penetrated through the connection block 12 accordingly.

[0057] Reference Figure 3 and Figure 4 Furthermore, the adjustable viewing head also includes an illumination element 7 disposed on the adjustment seat 2, and the illumination element 7 is electrically connected to the electrical connection portion 614 of the flexible circuit board 6. In a specific embodiment, the illumination element 7 is configured as two LEDs, and the two LEDs are symmetrically arranged on the upper and lower sides or the left and right sides of the camera 3; in other embodiments, the illumination element 7 can also be configured as four LEDs arranged around the camera 3.
