DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] The present utility model provides a bronchial endoscope, and its structure is as Figure 1 - Figure 4As shown in the figure, it includes a handle body 100, a driving mechanism 200 and a rotating mechanism 300. The handle body 100 includes a handle 110, an insertion tube 120 and a snake bone tube. One end of the insertion tube 120 is rotatably connected to one end of the handle 110, and one end of the snake bone tube is fixedly connected to the other end of the insertion tube 120. The driving mechanism 200 is connected to the snake bone tube and is used to drive the snake bone tube to bend alternately to both sides. The rotating mechanism 300 includes a rotating sleeve 310. One end of the rotating sleeve 310 is rotatably sleeved on the handle 110, and the other end of the rotating sleeve 310 is fixedly sleeved on the insertion tube 120. The rotating sleeve 310 can reciprocally rotate within 0° - 180°.

[0026] During use, first hold the handle 110 of the endoscope with one hand, and then use the other hand to control the driving mechanism 200 so that the driving mechanism 200 can drive the snake bone tube to bend alternately to both sides. Since the rotating sleeve 310 can reciprocally rotate within 0° - 180°, it can drive the insertion tube 120 to reciprocally rotate within 0° - 180°, and further drive the snake bone tube to reciprocally rotate within 0° - 180°, realizing the adjustment of the direction pointed by the snake bone tube, so that the movement path of the snake bone tube can cover the entire hemisphere. The operator no longer needs to change the direction of the snake bone tube by adjusting the handle 110, which not only reduces the operation difficulty of the operator, but also can more conveniently and quickly meet the requirements.

[0027] As a preferred embodiment, please refer to Figure 2 , the handle 110 has a cavity 111. One end of the cavity 111 is open, which is convenient for arranging the driving mechanism 200 in the cavity 111. The driving mechanism 200 is a prior art and will not be elaborated too much in this solution.

[0028] As a preferred embodiment, please refer to Figure 3 and Figure 4 , the handle body 100 further includes a mounting sleeve 130. One end of the mounting sleeve 130 is detachably fixed in the cavity 111, and the other end of the mounting sleeve 130 extends out of the cavity 111 along the opening of the cavity 111, which is convenient for one end of the insertion tube 120 to be rotatably connected to the mounting sleeve 130 to realize the rotatable connection with one end of the handle 110.

[0029] As a preferred embodiment, please refer to Figure 3 and Figure 4, the rotating mechanism 300 further includes a fixed sleeve 320. The fixed sleeve 320 is fixedly sleeved on the other end of the mounting sleeve 130. One end of the rotating sleeve 310 is rotatably sleeved on the fixed sleeve 320, preventing the fixed sleeve 320 from being directly rotatably sleeved on the handle 110, which may cause the size of the rotating mechanism 300 to be too large.

[0030] As a preferred embodiment, please refer to Figure 3 and Figure 4 , the handle body 100 further includes a connecting sleeve 140. One end of the connecting sleeve 140 is rotatably disposed inside the mounting sleeve 130. The other end of the connecting sleeve 140 extends out of the mounting sleeve 130 along the other end of the mounting sleeve 130. One end of the insertion tube 120 is fixedly disposed inside the connecting sleeve 140. The insertion tube 120 is fixedly connected to the connecting tube by bonding. The other end of the rotating sleeve 310 is detachably fixedly sleeved on the connecting sleeve 140, preventing the rotating sleeve 310 from being directly fixedly connected to the insertion tube 120, which may cause installation difficulties.

[0031] As a preferred embodiment, please refer to Figure 3 and Figure 4 , the rotating mechanism 300 further includes a limiting member 330. One end of the limiting member 330 is detachably fixedly disposed on the rotating sleeve 310. The other end of the limiting member 330 is used to abut against the fixed sleeve 320, so that the rotating sleeve 310 reciprocally rotates within 0° - 180°. To prevent the steel wires inside the insertion tube 120 from crossing and knotting, a limit is added between the rotating sleeve 310 and the fixed sleeve 320 to ensure that the rotating sleeve 310 can only rotate 90 degrees to the left or right, realizing the adjustment of the direction of the snake bone tube, so that the movement path of the snake bone tube can cover the entire hemisphere.

[0032] As a preferred embodiment, please refer to Figure 4 , a positioning groove 321 is formed on the fixed sleeve 320. The positioning groove 321 is a semi-circular structure. The other end of the limiting member 330 is slidably disposed inside the positioning groove 321. When the limiting member 330 moves to both ends of the positioning groove 321, it can be restricted by the positioning groove 321. At this time, the rotating sleeve 310 rotates 90 degrees to the left or right.

[0033] As a preferred embodiment, please refer to Figure 4 , a first screw hole 311 is formed on the rotating sleeve 310. The limiting member 330 is a bolt. The bolt penetrates through the first screw hole 311 and is connected to the first screw hole 311, making the disassembly and assembly of the limiting member 330 convenient.

[0034] As a preferred embodiment, please refer to Figure 4 , two notches 312 are further formed on the rotating sleeve 310, and the two notches 312 are oppositely arranged on both sides of the first screw hole 311. The rotating mechanism 300 further includes two elastic pieces, and the two elastic pieces are both arranged between the rotating sleeve 310 and the fixed sleeve 320. One ends of the two elastic pieces are opposite and detachably fixed on the outer side wall of the fixed sleeve 320. The two elastic pieces both extend radially and reversely along the fixed sleeve 320, and the other ends of the two elastic pieces both have a protrusion. When the bolt is located at the midpoint of the positioning groove 321, the two protrusions are respectively clamped in the corresponding notches 312, which is convenient for the operator to judge the position where he rotates through the sense of touch.

[0035] As a preferred embodiment, the rotating mechanism 300 further includes a plurality of fasteners. One end of each fastener is detachably fixed on the rotating sleeve 310, and the other end of each fastener is used to abut against the connecting sleeve 140, which is convenient for disassembling and assembling the rotating sleeve 310 and the connecting sleeve 140.

[0036] As a preferred embodiment, the handle body 100 further includes a camera, and the camera is fixed on the other end of the snake bone tube. The moving path of the snake bone tube can be photographed through the camera.

[0037] As a preferred embodiment, please refer to Figure 4 , a plurality of second screw holes 313 are circumferentially formed on the rotating sleeve 310. The fasteners are screws, and each screw respectively penetrates through the corresponding second screw hole 313 and is screwed with the second screw hole 313. Since the insertion tube 120 is fixedly connected to the connecting tube by an adhesive method, after the insertion tube 120 is adhered to the connecting tube, the position of the camera is fixed. Therefore, before assembling all the components and preparing to fix the positions of the rotating sleeve 310 and the connecting sleeve 140, first turn on the camera to ensure that the picture is perpendicular to the handle 110, and then tightly lock each screw. The end of each screw will press a pit on the surface of the connecting tube, so that the rotating sleeve 310 and the connecting sleeve 140 are firmly fixed, and at the same time, the relative rotation of the rotating sleeve 310 and the connecting sleeve 140 during long-term use can be effectively avoided.

[0038] As a preferred embodiment, please refer to Figure 3 and Figure 4 , the rotating mechanism 300 further includes a rotating sleeve 340, and the rotating sleeve 340 is detachably and fixedly sleeved on the rotating sleeve 310, which is convenient for manual rotation of the rotating sleeve 340 by a person.

[0039] As a preferred embodiment, please refer to Figure 3 and Figure 4 , the handle body 100 further includes a tapered sleeve 150, and the tapered sleeve 150 is detachably fixed on the outer side walls of the connecting sleeve 140 and the insertion tube 120, so that the insertion tube 120 is more stable.

[0040] To better understand the present invention, the working principle of the technical solution of the present invention will be described in detail below in conjunction with Figure 1 - Figure 4 :

[0041] During use, first hold the handle 110 of the endoscope with one hand, and then use the other hand to control the driving mechanism 200, so that the driving mechanism 200 can drive the snake bone tube to bend alternately to both sides, and the movement path of the snake bone tube can be photographed through the camera. When it is necessary to observe other positions, manually rotate the rotating sleeve 340 to drive the rotating sleeve 310 to rotate, so that the inner end of the bolt can slide in the positioning groove 321, thereby adjusting the direction of the snake bone tube. Since the positioning groove 321 is a semi-circular structure, when the limiting member 330 moves to both ends of the positioning groove 321, it can be restricted by the positioning groove 321. At this time, the rotating sleeve 310 rotates 90 degrees to the left or right, so that the rotating sleeve 310 can reciprocally rotate within 0° - 180°, thereby driving the insertion tube 120 to reciprocally rotate within 0° - 180°, and further driving the snake bone tube to reciprocally rotate within 0° - 180°, realizing the adjustment of the direction of the snake bone tube, so that the movement path of the snake bone tube can cover the entire hemisphere, and the operator does not need to change the direction of the snake bone tube by adjusting the handle 110 anymore, which not only reduces the operation difficulty of the operator, but also can more conveniently and quickly meet the requirements.

[0042] A bronchial endoscope provided by the present invention has the following beneficial effects:

[0043] (1) When the bolt is located at the midpoint of the positioning groove 321, the two protrusions are respectively clamped in the corresponding notch 312, which is convenient for the operator to judge the position reached by himself through the sense of touch;

[0044] (2) The positioning groove 321 is a semi-circular structure. When the limiting member 330 moves to both ends of the positioning groove 321, it can be restricted by the positioning groove 321. At this time, the rotating sleeve 310 rotates 90 degrees to the left or right, so that the rotating sleeve 310 can reciprocally rotate within 0° - 180°, avoiding the steel wires in the insertion tube 120 from crossing and knotting;

[0045] (3) It is possible to adjust the direction of the snake bone tube, so that the movement path of the snake bone tube can cover the entire hemisphere. The operator no longer needs to adjust the direction of the snake bone tube by adjusting the handle 110, which not only reduces the operation difficulty of the operator, but also can meet the requirements more conveniently and quickly.

[0046] The specific implementation manners of the present invention described above do not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention shall be included in the protection scope of the claims of the present invention.
