[0027] This specific embodiment is a hysteroscopic endoscope for obstetrics and gynecology that is easy to adjust. Figure 1-Figure 5As shown, the endoscope includes an endoscope body 1, an endoscope tube 2 is installed on the left side of the endoscope body 1, a transparent tube head 4 is fixedly connected to the left side of the endoscope tube 2, a searchlight assembly 5 is installed inside the transparent tube head 4, a cavity 6 is opened inside the right side of the endoscope body 1, a first rack 7 and a second rack 8 are slidably connected to the upper and lower sides of the cavity 6, the left sides of the first rack 7 and the second rack 8 are connected to the searchlight assembly 5 by the first pull rope 9 and the second pull rope 10 respectively, an adjustment assembly 11 is arranged between the first rack 7 and the second rack 8, and the adjustment assembly 11 is used to drive the searchlight assembly 5 to adjust through the first pull rope 9 and the second pull rope 10.
[0028] like Figure 1 and Figure 2 As shown: In this embodiment, a handle 3 is fixedly connected to the lower surface of the endoscope body 1, and the handle 3 includes two grips, so that it is more convenient to hold the two grips on the handle 3 during use.
[0029] like Figure 2 and Figure 3 As shown: In this embodiment, a channel 12 is opened inside the endoscope 2 and is interconnected with the cavity 6. The endoscope 2 is a hard structure, and the transparent tube head 4 is threadedly connected to the endoscope 2, so that the first pull rope 9 and the second pull rope 10 can pass through the channel 12, and the transparent tube head 4 can protect the searchlight component 5, and the transparent tube head 4 is threadedly connected to the endoscope 2, which is very convenient to install.
[0030] like Figure 2 , Figure 3 and Figure 4 As shown in the figure: In this embodiment, the searchlight assembly 5 includes an endoscope lens 501, a searchlight 502 and a wire 503. A mounting frame 504 is fixedly connected to the left side of the endoscope tube 2. The left side of the mounting frame 504 is rotatably connected to a mounting plate 506 through a reset assembly 505. The endoscope lens 501 and the searchlight 502 are both mounted on the mounting plate 506. One end of the wire 503 is electrically connected to the endoscope lens 501 and the searchlight 502. The other end of the wire 503 passes through the channel 12 and extends to the outside of the endoscope body 1. The first pull The rope 9 and the second pull rope 10 both pass through the channel 12 and are fixedly connected to the upper and lower ends of the mounting plate 506 respectively. The reset assembly 505 includes a U-shaped seat 5051 fixedly connected to the mounting frame 504. A connecting rod 5052 is fixedly connected to the right side of the mounting plate 506. A round shaft 5053 is fixedly connected to the right side of the connecting rod 5052. The round shaft 5053 is rotatably connected to the inside of the U-shaped seat 5051 through a bearing. A reaction force torsion spring 5054 is installed on the outer surface of the round shaft 5053 and between the inner wall of the U-shaped seat 5051.
[0031] In this way, when the first pull rope 9 and the second pull rope 10 move in opposite directions, the first pull rope 9 drives the mounting plate 506, the endoscope lens 501 and the searchlight 502 to rotate around the circular axis 5053, and the reaction force torsion spring 5054 is compressed to facilitate reset;
[0032] There are two reaction force torsion springs 5054, which are respectively arranged on the front and rear sides of the round shaft 5053. The specific reaction force torsion spring 5054 is a special spring designed to generate a reaction force when subjected to an external force. Compared with ordinary torsion springs, the reaction force torsion spring 5054 pays more attention to its performance and stability in reverse torsion in design and material selection. Therefore, the reaction force torsion spring 5054 can be reversely twisted to a certain extent.
[0033] like Figure 2 and Figure 5 As shown: In this embodiment, the first rack 7 and the second rack 8 are both fixedly connected with a movable block 13 on the side away from each other, and two sliding rods 14 are fixedly connected to the upper and lower ends of the left inner wall of the cavity 6. The sliding rod 14 passes through the movable block 13 and is fixedly connected to the right inner wall of the cavity 6. The sliding rod 14 is slidably connected to the movable block 13;
[0034] The slide bar 14 makes the movable block 13 and the rack move more stably, avoids tilting, and makes the first rack 7 and the second rack 8 slide left and right better.
[0035] like Figure 2 and Figure 5 As shown: In this embodiment, the adjustment component 11 includes a rotating shaft 1101 rotatably connected to the inner wall of the back side of the cavity 6, and the outer surface of the rotating shaft 1101 is fixedly connected to a gear 1102 and a worm wheel 1103, the worm wheel 1103 is located at the rear side of the gear 1102, the first rack 7 and the second rack 8 are meshed with the gear 1102, and the right side of the worm wheel 1103 is meshed with a worm 1104, the top end of the worm 1104 passes through the endoscope body 1 and is fixedly connected to a handle 1105, and the worm 1104 is rotatably connected to the endoscope body 1 through a bearing;
[0036] When the angle needs to be adjusted, turn the handle 1105 to drive the worm 1104 to rotate. During the rotation process, the worm 1104 cooperates with the worm wheel 1103 to drive the rotating shaft 1101 and the gear 1102 to rotate. At this time, the gear 1102 drives the first rack 7 and the first pull rope 9 to move to the right, and the second rack 8 and the second pull rope 10 to move to the left, so that the first pull rope 9 and the second pull rope 10 move in opposite directions.
[0037] like Figure 1 and Figure 2As shown: In this embodiment, the cavity 6 runs through the front side of the endoscope body 1, and the front side of the endoscope body 1 is fixedly connected with a cover plate 15 corresponding to the cavity 6 by screws, so that the components inside the cavity 6 can be easily installed.
[0038] Working principle: When in use, hold the handle 3, insert the endoscope 2 and the transparent tube head 4 into the uterine cavity of the body, and shoot the picture through the endoscope lens 501. When the angle needs to be adjusted, turn the handle 1105 forward to drive the worm 1104 to rotate. During the rotation process, the worm 1104 cooperates with the worm wheel 1103 to drive the rotating shaft 1101 and the gear 1102 to rotate. At this time, the gear 1102 drives the first rack 7 and the first pull rope 9 to move to the right, and the second rack 8 and the second pull rope 10 to move to the left. Since the first pull rope 9 and the second pull rope 10 move in opposite directions, the first pull rope 9 drives the mounting plate 506, the endoscope lens 501 and the probe lens 501 to rotate. The lamp 502 rotates upward around the circular axis 5053 and compresses the reaction force torsion spring 5054. When reverse adjustment is required, the reverse handle 1105 drives the worm 1104 to rotate. At this time, the gear 1102 drives the first rack 7 and the first pull rope 9 to move to the left, and the second rack 8 and the second pull rope 10 move to the right. Since the first pull rope 9 and the second pull rope 10 move in opposite directions, the second pull rope 10 drives the mounting plate 506, the endoscope lens 501 and the searchlight 502 to rotate downward around the circular axis 5053, so as to facilitate the adjustment of the angle of the searchlight assembly 5, which is convenient for medical staff to collect images of various directions of the patient's treatment site, thereby improving the practicality of the hysteroscopic endoscope.
[0039] All technical features in this embodiment can be freely combined according to actual needs.
[0040] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
