[0027] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, this embodiment provides a hand-controlled direction adjustment device for an endoscope, including a mounting shell 100, a first drive ring 200, a second drive ring 300, a drive motor 400 and a finger control sleeve 500; a first mounting groove 110 is provided in the mounting shell 100, and the first drive ring 200 is rotatably mounted in the first mounting groove 110, and a second mounting groove 120 for mounting the second drive ring 300 is provided in the first mounting groove 110, and the second drive ring 300 is located inside the first drive ring 200; a connecting channel is provided in the bottom area of ​​the first mounting groove 110 and the second mounting groove 120 of the mounting shell 100 130, both the first drive ring 200 and the second drive ring 300 are capable of being connected to their respective drive motors 400 in transmission; both the first drive ring 200 and the second drive ring 300 are capable of being adapted to the double-layer adjustment button 610 on the endoscope operating handle 600, so that the first drive ring 200 can drive the up and down angle knobs 611 to rotate, and the second drive ring 300 can drive the left and right angle knobs 612 to rotate; the finger control sleeve 500 is arranged on the outside of the mounting shell 100, and a plurality of control sensors 510 are provided in the finger control sleeve 500, so that the user can control the corresponding drive motor 400 through the control sensor 510.

[0028] Specifically, the mounting shell 100 is covered on the operating handle of the endoscope, and the double-layer adjustment button 610 on the endoscope operating handle 600 corresponds to the first drive ring 200 and the second drive ring 300. Specifically, the first drive ring 200 can drive the up and down angle knob 611 to rotate, and the second drive ring 300 can drive the left and right angle knob 612 to rotate. During use, the doctor holds the endoscope operating handle 600 with one hand, and the index finger of this hand is inserted into the finger control sleeve 500. When the doctor's index finger moves up, down, left and right, it can trigger the control sensor 510 located on the inner wall of the finger control sleeve 500 to work, thereby controlling the corresponding drive motor 400 to work. The output end of the drive motor 400 can pass through the connecting channel 130 to drive the corresponding drive ring to rotate, thereby changing the bending direction of the front end of the endoscope. Through such a setting, the bending direction of the endoscope is changed from the original doctor needing to turn the angle knob with his fingers to simply moving the index finger in different directions, thereby reducing the workload of the doctor's fingers, alleviating the doctor's fatigue, and reducing the chance of medical accidents due to fatigue.

[0029] The bottom of the mounting housing 100 is provided with a wrapping strap, which is provided with Velcro, so that the mounting housing 100 can be fixedly mounted on the operating handle of the endoscope. Alternatively, the mounting housing 100 includes an upper housing and a lower housing, which are detachably connected. When in use, the upper housing and the lower housing can be separated and then placed on both sides of the endoscope operating handle 600, and then the upper housing and the lower housing are connected.

[0030] See also Figures 1-11 As shown, in an optional solution of this embodiment, the outer rings of both the first drive ring 200 and the second drive ring 300 are provided with guide snap rings 720; and the first installation groove 110 and the second installation groove 110 are both provided with guide snap rings 730 adapted to the guide snap rings 720.

[0031] The longitudinal section of the guide clamping ring 720 is semicircular.

[0032] Specifically, guide slots 730 are provided in both the first mounting groove 110 and the second mounting groove 110, and guide snap rings 720 are provided on the outer rings of both the first drive ring 200 and the second drive ring 300. When the first drive ring 200 is installed in the first mounting groove 110, the guide snap ring 720 on the outer side of the first drive ring 200 can be snapped into the guide slot 730 of the first mounting groove, thereby completing the installation and fixation of the first drive ring 200 and enabling the first drive ring 200 to rotate relative to the first mounting groove 110. When the second drive ring 300 is installed in the second mounting groove 120, the guide snap ring 720 on the outer side of the second drive ring 300 can be snapped into the guide slot 730 of the second mounting groove, thereby completing the installation and fixation of the second drive ring 300 and enabling the second drive ring 300 to rotate relative to the second mounting groove 120.

[0033] It should be pointed out that the guide snap ring 720 on the first drive ring 200 and the second drive ring 300 can be made of plastic or copper, and the guide snap ring 720 and the guide slot 730 are clearance-matched so that during the assembly process, the staff can press the guide snap ring 720 into the guide slot 730 to ensure subsequent normal operation.

[0034] See also Figures 1-11 As shown, in an optional solution of this embodiment, the first driving ring 200 has a first driving protrusion 210 adapted to the upper and lower angle knobs 611, so that when the first driving ring 200 rotates, the upper and lower angle knobs 611 are driven to rotate synchronously through the first driving protrusion 210.

[0035] Specifically, a first driving protrusion 210 is provided on the first driving ring 200. When the mounting shell 100 is installed on the endoscope operating handle 600, the first driving protrusion 210 on the first driving ring 200 can be embedded in the upper and lower angle knobs 611, so that when the first driving ring 200 rotates, the upper and lower angle knobs 611 can be driven to rotate synchronously.

[0036] See also Figures 1-11 As shown, in an optional solution of this embodiment, the second driving ring 300 has a second driving protrusion 310 adapted to the left and right angle knobs 612, so that when the second driving ring 300 rotates, the left and right angle knobs 612 are driven to rotate synchronously through the second driving protrusion 310.

[0037] Specifically, a second driving protrusion 310 is provided on the second driving ring 300. When the mounting shell 100 is installed on the endoscope operating handle 600, the second driving protrusion 310 on the second driving ring 300 can be embedded in the left and right angle knobs 612, so that when the second driving ring 300 rotates, it can drive the left and right angle knobs 612 to rotate synchronously.

[0038] Among them, the left and right angle knobs 612 are located above the upper and lower angle knobs 611, and the size of the left and right angle knobs 612 is smaller than the upper and lower angle knobs 611. Therefore, the second mounting groove 120 is located in the first mounting groove 110, and there is a height difference between the second drive ring 300 and the first drive ring 200, so that the first drive ring 200 can drive the upper and lower angle knobs 611, and the second drive ring 300 can drive the left and right angle knobs 612.

[0039] See also Figures 1-11 As shown, in an optional scheme of this embodiment, the drive motor 400 includes a first drive motor 410 and a second drive motor 420, and both the first drive motor 410 and the second drive motor 420 are arranged on the mounting shell 100; both the first drive ring 200 and the first drive ring 200 are provided with an end gear 710, and the output ends of both the first drive motor 410 and the second drive motor 420 are provided with a transmission member 430, and the transmission member 430 is connected to the end gear 710 through the connecting channel 130.

[0040] Specifically, both the first drive motor 410 and the second drive motor 420 are arranged on the mounting shell 100, and the front end of the first drive motor 410 is connected to the end face gear 710 on the first drive motor 410 through the transmission member 430, and the front end of the second drive motor 420 is connected to the end face gear 710 on the second drive motor 420 through the transmission member 430. The transmission member 430 can pass through the connecting channel 130, thereby realizing the rotation of the upper and lower angle knobs 611 and the left and right angle knobs 612.

[0041] The first driving motor 410 and the second driving motor 420 are both micro motors.

[0042] See also Figures 1-11 As shown, in an optional solution of this embodiment, the finger control sleeve 500 includes an operating sleeve 520 and multiple control sensors 510; the multiple control sensors 510 are arranged on the inner wall of the operating sleeve 520 along the circumference of the operating sleeve 520; and an auxiliary seat 530 for suspending the finger is provided at the bottom of the operating sleeve 520.

[0043] Specifically, the control sensor 510 can be a pressure sensor. At least four control sensors 510 are arranged on the inner wall of the operating sleeve 520. The four control sensors 510 are divided into two groups of control units arranged opposite to each other. The two groups of control units respectively control the first drive motor 410 and the second drive motor 420.

[0044] For example, when the doctor holds the endoscope operating handle 600, the doctor's index finger moves upward to trigger the upper control sensor 510. At this time, the first drive motor 410 drives the first drive ring 200 to rotate, thereby driving the upper and lower angle knobs 611 to rotate, so that the front end of the endoscope bends upward. When the doctor's index finger no longer triggers the upper control sensor 510, the first drive motor 410 stops working. When the doctor's index finger triggers the lower control sensor 510, the first drive motor 410 rotates in the opposite direction, so that the front end of the endoscope bends downward.

[0045] In addition, when the doctor's index finger moves toward the seat, it can trigger the control sensor 510 on the seat side. At this time, the first drive motor drives the second drive ring 300 to rotate, thereby driving the left and right angle knobs 612 to rotate, so that the front end of the endoscope bends to the left. When the doctor's index finger no longer triggers the control sensor 510 on the left, the second drive motor 420 stops working. When the doctor's index finger triggers the control sensor 510 on the right, the second drive motor 420 rotates in the opposite direction, so that the front end of the endoscope bends to the right.

[0046] It should be noted that two finger control sleeves 500 may be provided, one containing a control sensor 510 for controlling the first drive motor 410, and the other containing a control sensor 510 for controlling the second drive motor 420. Those skilled in the art may adjust the number of finger control sleeves 500 according to actual needs.

[0047] It should be noted that an auxiliary seat 530 for finger suspension is provided at the bottom of the operating sleeve 520. When the doctor does not need to adjust the bending angle of the front end of the endoscope, the doctor's index finger can fall on the auxiliary seat 530 to prevent the index finger from triggering the outer control sensor 510.

[0048] This embodiment provides an endoscope, including a manual direction adjustment device for the endoscope.

[0049] Specifically, the manual direction adjustment device for the endoscope provided in this embodiment can be installed on the control handle of the endoscope, so that the installation shell 100 of the manual direction adjustment device for the endoscope is covered on the double-layer adjustment button 610 of the endoscope operating handle 600, thereby facilitating medical personnel to operate the bending direction of the front end of the endoscope.

[0050] In addition, the endoscope provided in this embodiment has the advantages of the above-mentioned endoscope with a manual direction adjustment device compared with the prior art, which will not be described in detail here.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
