[0032] The existing hard tube endoscope places the camera device in the guide tube, and the cross section of the front end of the guide tube is perpendicular to the guide tube axis, so that the camera device can only shoot the image in front of the end of the guide tube, so the shooting range is small, and because the guide tube is hard and cannot be bent, adjusting the position of the guide tube axis will cause strong discomfort to the patient. Therefore, the prominent problem of the current hard tube endoscope is that the shooting image range is small, which is not convenient for the doctor to observe and operate.

[0033] The utility model provides a kind of hard tube endoscope.

[0034] Please refer to Figure 1 In an embodiment of the present application, the hard tube endoscope 100 comprises a guide tube 1, a light-transmitting sheet 2 and a camera device 3. The guide tube 1 has a first mounting channel 11 and an insertion end 12 penetrating along its axial direction. The end surface of the insertion end 12 is inclined relative to its radial direction. The guide tube 1 has a rotation stroke of rotation along its axial line. The insertion end 12 of the guide tube 1 is used to extend into the patient's body. The light-transmitting sheet 2 is arranged on the insertion end 12 to close one end opening of the first mounting channel 11. The camera device 3 is mounted in the first mounting channel 11, adjacent to the insertion end 12, and arranged towards the end surface of the insertion end 12.

[0035] The technical solution of the present application inclines the end surface of the insertion end 12 of the guide tube 1, and correspondingly inclines the camera device 3, so that the camera device 3 can shoot the image in front and also shoot part of the lateral image. By rotating the guide tube 1, the image in front can be observed by rotation, the lateral field of view is expanded, and the range that the camera device 3 can shoot is expanded. The rotation of the guide tube 1 does not involve the change of the position and posture of the guide tube 1, and has less impact on the patient.

[0036] In order to acquire the lateral view, the size of the front view also needs to be ensured, and in the case of ensuring that a large amount of front view can be acquired during shooting, a part of the lateral view is also needed, so the angle between the end face of the insertion end 12 and the radial direction of the guide tube 1 is A, 15°≤A≤45°, and when A=45°, half of the image shot is the front view and half is the lateral view, and when A<45°, the front view occupies most of the image shot.

[0037] In order to realize the rotation of the guide tube 1, the guide tube 1 has a connecting end 13 opposite to the insertion end 12 in the extension direction, and the hard tube endoscope 100 further comprises a sleeve 4 having a second mounting channel 41 extending through the sleeve 4 in the axial direction and extending in the same direction as the guide tube 1, the connecting end 13 is inserted into the second mounting channel 41 and is limitingly mounted in the second mounting channel 41 in the extension direction of the guide tube 1, preventing the guide tube 1 from changing the position of the insertion end 12 during rotation. In one embodiment, the following structure is provided: a limiting hole 42 is formed in the side wall of the sleeve 4, the limiting hole 42 extends in the circumferential direction of the sleeve 4, the connecting end 13 extends in the radial direction to form an operating part 14, and the operating part 14 penetrates the limiting hole 42. The doctor can rotate the guide tube 1 by rotating the operating part 14. In the axial direction of the guide tube 1, the size of the limiting hole 42 is comparable to the size of the operating part 14, so the operating part 14 cannot move in the axial direction of the guide tube 1.

[0038] In order to realize the rotation of the guide tube 1, the guide tube 1 needs to be movable in the extension direction, which is a function required for the guide tube 1 to extend to the lesion site, so in one embodiment, the following specific structure is designed: the hard tube endoscope 100 further comprises a mounting seat 5, a clamping part 6, a matching part 7, a rack 8, a gear 9 and an operating rod 10; the mounting seat 5 has a mounting part 51 provided with a cavity 511 opening on one side; the clamping part 6 is correspondingly provided on the side opening of the mounting part 51 and is fixedly connected with the mounting part 51; the matching part 7 is fixedly provided on the outer side of the sleeve 4 and is used to cooperate with the clamping part 6, and the matching part 7 has an active stroke in the extension direction of the sleeve 4 relative to the clamping part 6; the rack 8 is fixedly provided on the outer side of the sleeve 4 and extends in the same direction as the sleeve 4; the gear 9 is rotatably installed in the cavity 511 and partially extends to the outside of the opening of the mounting part 51 to engage with the rack 8; and the operating rod 10 penetrates the mounting seat 5 and is fixedly connected with the gear 9. By rotating the operating rod 10 by the doctor, the gear 9 is rotated, the gear 9 drives the rack 8 to move, thereby making the sleeve 4 move along its own axial direction, thereby driving the guide tube 1 to move.

[0039] In order to ensure the cooperation between the gear 9 and the rack 8 without separation, the distance between the mounting portion 51 and the sleeve 4 in the radial direction of the sleeve 4 is kept unchanged, and only the axial relative sliding between the two is allowed. In an embodiment, the cooperation portion 7 comprises a clamping groove 71 extending in the same direction as the sleeve 4, and the clamping portion 6 comprises a clamping block 61 cooperating with the clamping groove 71.

[0040] Since the insertion end 12 is inserted into the human body, the light transmission sheet 2 is easily contaminated. Therefore, in an embodiment, a through hole 21 is formed on the light transmission sheet 2, and the hard tube endoscope 100 further comprises a water pipe 20 at least partially installed in the first installation channel 11. The water outlet end of the water pipe 20 is arranged corresponding to the through hole 21, and the water inlet end of the water pipe 20 extends out of the guide tube 1 to be connected with a water supply device. The water is introduced to the outside of the light transmission sheet 2 to clean the outside of the light transmission sheet 2, thereby avoiding the step of pulling out the guide tube 1 for cleaning. Moreover, the guide tube 1 is rotated during cleaning to make the water flow to more positions, thereby obtaining a better cleaning effect. The water supply device can be provided with the hard tube endoscope 100 or can be an external device, which is flexibly arranged according to the requirement.

[0041] A light source is also needed when the image inside the human body is taken. Therefore, the hard tube endoscope 100 further comprises a light guide fiber 30 installed in the first installation channel 11. One end of the light guide fiber 30 close to the insertion end 12 is arranged in the same direction as the direction of the camera 3, so that the light intensity at the shooting position is maximized to obtain the best shooting effect. In addition, a plurality of light guide fibers 30 can be arranged if the installation space permits.

[0042] In order to see the inside of the human body in real time, the hard tube endoscope 100 further comprises a display, and the camera 3 is electrically connected with the display.

[0043] When the position of the guide tube 1 is adjusted, it is necessary to ensure that the mounting seat 5 is fixed. Therefore, the hard tube endoscope 100 further comprises a mounting seat 5 and an electromagnetic relay, and the electromagnetic relay is fixedly arranged on the mounting seat 5. When the hard tube endoscope 100 is used, the electromagnetic relay is energized to be fixedly connected with an iron bed guardrail or a table top.

[0044] The above description is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
