Description

Technical Field

[0001] The invention relates to the field of medical instruments, and in particular to an auxiliary bending device which can enable an endoscope to approach a lesion. Background Art

[0002] In clinical work, doctors often use endoscopes to observe ulcers or tumors in the stomach and intestines. It can be inserted into the stomach or intestines through the mouth. When doctors use endoscopes to examine the stomach and intestines, or when they need to use endoscopes to perform gastrointestinal surgery, they insert the end of the endoscope insertion tube with the lens into the mouth (the end of the insertion tube with the lens is the insertion end). After reaching the stomach and intestines, in order to observe or facilitate surgery, the side of the insertion tube close to the observation mirror needs to be bent, thereby changing the observation direction of the observation mirror or changing the direction in which the surgical instrument extends from the surgical instrument channel;

[0003] Patent: CN109497912B provides an endoscope auxiliary bending device and an endoscope thereof, belonging to the field of medical devices. It solves the problem that the bending amplitude of the bending part of the existing endoscope insertion tube cannot meet the requirements. An endoscope auxiliary bending device includes a sleeve and a pull rope. The sleeve is used to be sleeved on the outside of the insertion tube. The sleeve is provided with a pull rope channel for the pull rope to pass through. The pull rope channel is used to move the pull rope along the length direction of the insertion tube. A fixing ring is provided at one end of the pull rope. The fixing ring is used to fix one end of the pull rope to the side of the insertion tube close to the observation mirror. The pull rope is used to increase the bending amplitude of the bending part. The present invention can further increase the bending amplitude of the bending part;

[0004] In the above technology, the bending direction is adjusted in a single direction, resulting in incomplete observation direction of the observation mirror, and it is not convenient to assist the endoscope in feeding the wire, and the feeding angle cannot be adjusted.

[0042] When the endoscope line is passed into the human body, the handheld worm 305 can be rotated, and then under the meshing transmission of the two transmission gears 303, the two active rollers 302 can be controlled to rotate together, thereby pushing the endoscope line to move, which is convenient for adjusting the depth after penetration into the human body.

[0043] like Figure 1 and Figure 2 As shown, the left and right sides of the wire feeding mechanism 3 are respectively provided with an inlet pipe 4 and an outlet pipe 5, a concave member 6 is fixedly connected to the right side of the outer wall of the outlet pipe 5, and a cross arm 7 is rotatably connected to the inner side of the concave member 6 through a rotating shaft;

[0048] The horizontal arm 7 can be rotated to adjust the inclination as needed, so as to adjust the penetration height of the observation mirror when it is introduced into the human body. The wire entry tube head 14 can be rotated to adjust the penetration angle, and the angle of the wire entry tube head 14 after the angle adjustment can be positioned by rotating the fastening bolt 12;

[0049] By pulling one of the multiple traction ropes 16, the fastening ring 15 drives the observation mirror to move, so that the endoscope pipeline is bent, and the multiple traction ropes 16 can pull the endoscope pipeline to bend in different directions, thereby increasing the range of bending detection.

[0050] like Figure 1 and Figure 2 As shown, a support adjustment mechanism 8 is provided between the cross arm 7 and the base 1;

[0051] The supporting and adjusting mechanism 8 includes two rotating seats 801, and a threaded rod 802 is rotatably connected between the two rotating seats 801 via a rotating shaft.

[0053] By rotating the threaded rod 802 and controlling the movement of the threaded sleeve 803, the movement of the support rod 805 can drive the cross arm 7 to move together, and then adjust the inclination of the cross arm 7 to achieve the effect of adjusting the penetration height of the control observation mirror when it is introduced into the human body, and can provide stable support.

[0054] like Figure 1 , Figure 5 and Figure 6 As shown, the upper surface of the cross arm 7 is fixedly connected with a winding mechanism 9;

[0056] A through opening 18 is provided on the front surface of the cross arm 7. A mounting plate 19 is fixedly connected to the front surface of the cross arm 7 below the through opening 18. A driven roller 20 is rotatably connected to the upper surface of the mounting plate 19 and located inside the through opening 18 via a rotating shaft.

[0059] The right side of the storage box 901 is located above and below the traction rope 903, and is fixedly connected with a rotating joint 905. Both sides of the rotating joint 905 are rotatably connected with extrusion parts 906 through a rotating shaft. A linkage part 907 is integrally formed on the top of the rotating joint 905 above the displacement traction rope 903. The opposite sides of the two linkage parts 907 are rotatably connected with a threaded sleeve 908 through a rotating shaft.

[0062] Then, under the linkage of the linkage piece 911, the two extrusion parts 906 can be controlled to move, and the two upper and lower opposite extrusion wheels 912 can be controlled to clamp the traction rope 2 903 and pull it toward the storage box 901, so as to control the traction rope 16 to pull and control the bending of the endoscope pipeline to achieve the control effect of adjusting the endoscope observation angle. After adjustment, the stability of the endoscope at the current observation angle can be ensured. By setting multiple threaded rods 2 909, multiple traction ropes 16 and traction ropes 2 903 can be controlled respectively, and the endoscope can be pulled to bend in different directions, making the observation more comprehensive.
