Description
Technical Field
[0001] This utility model relates to the technical field of combined speculum for hysteroscopic surgery, specifically to a combined speculum for hysteroscopic surgery. Background Technology
[0002] Hysteroscopic surgery refers to minimally invasive surgery performed using a hysteroscope. A hysteroscope is an advanced device for diagnosing and treating diseases within the uterine cavity. It allows for clear observation of various changes within the uterine cavity, enabling accurate diagnosis. Currently, a speculum is used to assist in hysteroscopic surgery; therefore, there is a need to invent a combined speculum for hysteroscopic surgery.
[0003] The current publication number CN202437958U discloses a combined speculum, including an upper body and a lower body. The upper body includes an upper rear end and an upper front end, and the lower body includes a lower rear end and a lower front end. The upper and lower rear ends are hinged together to form a handheld end. The upper and lower front ends are respectively duckbill-shaped upper and lower pages. The upper and lower front ends are separately installed on the upper and lower rear ends and can be detached from them. After a gynecological examination or surgery, the disposable part can be removed and replaced with a new disposable part for the next gynecological examination or surgery. Compared with existing disposable speculums, the disposable part of this utility model has a simple structure and low cost, and is small in size, uses less material, reduces usage costs, and reduces environmental pollution caused by white waste.
[0004] To address the issues with the use of combined speculum devices in the aforementioned solutions, existing technologies employ separate installation of the front and rear ends of the upper and lower body, respectively, allowing for detachment from these ends. However, this approach still presents challenges in adjusting the speculum's opening range, resulting in inconvenience, inflexibility, and low efficiency in its use. Utility Model Content
[0005] The purpose of this invention is to provide a combined speculum for hysteroscopic surgery to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A combined speculum for hysteroscopic surgery includes a handle, an adjustment mechanism mounted on one end of the handle, the adjustment mechanism including a maintenance box, a rotating shaft rotatably connected inside the maintenance box, a first bevel tooth and a second bevel tooth fixedly connected to both ends of the rotating shaft, a third bevel tooth meshing with the surfaces of the first bevel tooth and the second bevel tooth, and a torsion block fixedly connected to one end of the rotating shaft.
[0008] A further improvement of this utility model is that: a lower body is threadedly installed on one side of the maintenance box, and a threaded bolt is fixedly connected to the surface of the third bevel tooth, which drives the threaded bolt to rotate.
[0009] A further improvement of this utility model is that: a top plate is fixedly connected to the top of the threaded bolt, a connecting plate is threadedly connected to the surface of the threaded bolt, and an upper body is fixedly connected to the surface of the connecting plate. The threaded bolt drives the connecting plate to move up and down, thereby driving the upper body to move. When the upper body moves, the top plate limits the upward movement of the upper body.
[0010] A further improvement of this utility model is that a lighting mechanism is installed on the surface of the upper body, and the lighting mechanism is used for lighting.
[0011] A further improvement of the present invention is that the lighting mechanism includes a mounting hole, a fixed sleeve is installed inside the mounting hole, movable holes are provided on both sides of the fixed sleeve, and connecting sleeves are fixedly connected to both sides of the fixed sleeve via a connecting pipe.
[0012] A further improvement of this utility model is that: the surface of the connecting sleeve is threaded with an upper through pipe, the surface of the upper through pipe is fixedly connected with a handle, one end of the connecting pipe is fixed with an L through pipe, and one end of the L through pipe is equipped with a light. By holding the handle, the upper through pipe, the connecting pipe and the L through pipe are moved. When the upper through pipe, the connecting pipe and the L through pipe move, they move on the hemisphere through the connecting sleeve.
[0013] A further improvement of this utility model is that: a hemisphere is rotatably connected inside the connecting sleeve, and a movable sleeve post is fixedly connected to one end of the hemisphere. The movable sleeve post is movably connected through the inside of the movable hole. When the lighting mechanism needs to be cleaned and disassembled, the movable sleeve post and the hemisphere are pulled out from the movable hole and the connecting sleeve, and then the upper tube is rotated so that the upper tube is detached from the connecting tube, so that the L-tube can be separated.
[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0015] This invention provides a combined speculum for hysteroscopic surgery. By rotating a torsion block, the torsion block drives a rotating shaft to rotate, which in turn drives a first and second conical tooth to rotate. The first and second conical teeth then drive a third conical tooth to rotate, which in turn drives a threaded bolt to rotate. The threaded bolt then drives a connecting plate to move up and down, thereby moving the upper body. During the movement of the upper body, the top plate limits the upward movement of the upper body, allowing for flexible adjustment of the opening range of the upper body. This facilitates flexible operation by the doctor and improves surgical efficiency.
[0016] This utility model provides a combined speculum for hysteroscopic surgery. By holding the handle, the upper tube, connecting tube, and L-tube can be moved. During movement, the upper tube, connecting tube, and L-tube move on the hemispherical sleeve, allowing the overall lighting mechanism to move flexibly and adjust the angle of the lighting lamp. When the lighting mechanism needs to be cleaned and disassembled, the movable sleeve and hemispherical body are pulled out from the movable hole and connecting sleeve, and then the upper tube is rotated to detach from the connecting tube, allowing the L-tube to be separated. This allows for convenient lighting during surgery while also enabling disassembly and disinfection of the lighting mechanism, improving the overall practicality of the device.

[0022] The present invention will be further described in detail below with reference to embodiments: Example
[0023] like Figure 1-4As shown, this utility model provides a combined speculum for hysteroscopic surgery, including a handle 4. One end of the handle 4 is equipped with an adjustment mechanism 3. The adjustment mechanism 3 includes a maintenance box 30. The inside of the maintenance box 30 is rotatably connected to a rotating shaft 31. The two ends of the rotating shaft 31 are fixedly connected to a first bevel tooth 32 and a second bevel tooth 33. The surfaces of the first bevel tooth 32 and the second bevel tooth 33 are meshed with a third bevel tooth 35. One end of the rotating shaft 31 is fixedly connected to a torsion block 34. A lower body 2 is threadedly installed on one side of the maintenance box 30. A threaded bolt 36 is fixedly connected to the surface of the third bevel tooth 35. A top plate 37 is fixedly connected to the top of the threaded bolt 36. A connecting plate 38 is threadedly connected to the surface of the threaded bolt 36. An upper body 1 is fixedly connected to the surface of the connecting plate 38.
[0024] Specifically, by rotating the torsion block 34, the torsion block 34 drives the rotating shaft 31 to rotate, the rotating shaft 31 drives the first bevel tooth 32 and the second bevel tooth 33 to rotate, the first bevel tooth 32 and the second bevel tooth 33 drive the third bevel tooth 35 to rotate, the third bevel tooth 35 drives the threaded bolt 36 to rotate, and the threaded bolt 36 drives the connecting plate 38 to move up and down, thereby driving the upper body 1 to move. When the upper body 1 moves, the top plate 37 limits the upward movement of the upper body 1. Example
[0025] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the lighting mechanism 5 includes a mounting hole 50, a fixed sleeve 51 is installed inside the mounting hole 50, movable holes 52 are opened on both sides of the fixed sleeve 51, a connecting pipe 56 is movably connected to the surface of the fixed sleeve 51, a connecting sleeve 55 is fixedly connected to both sides of the connecting sleeve 51, an upper through pipe 58 is threadedly connected to the surface of the connecting sleeve 55, a handle 59 is fixedly connected to the surface of the upper through pipe 58, an L-through pipe 57 is fixed to one end of the connecting pipe 56, a lighting lamp 591 is installed at one end of the L-through pipe 57, a hemisphere 54 is rotatably connected inside the connecting sleeve 55, a movable sleeve post 53 is fixedly connected to one end of the hemisphere 54, and the movable sleeve post 53 is movably connected through the interior of the movable hole 52;
[0026] Specifically, when the doctor performs surgery, he moves the upper tube 58, connecting tube 56, and L-tube 57 by holding the handle 59. When the upper tube 58, connecting tube 56, and L-tube 57 move, they move on the hemispherical ball 54 through the connecting sleeve 55, thereby allowing the overall lighting mechanism 5 to move flexibly and adjusting the angle of the lighting lamp 591. When it is necessary to clean and disassemble the lighting mechanism 5, the movable sleeve 53 and the hemispherical ball 54 are pulled out from the movable hole 52 and the connecting sleeve 55, and then the upper tube 58 is rotated to detach the upper tube 58 from the connecting tube 56, so that the L-tube 57 can be separated.
[0027] The working principle of this combined speculum used in hysteroscopic surgery will be explained in detail below.
[0028] like Figure 1-4 As shown, by rotating the torsion block 34, the torsion block 34 drives the rotating shaft 31 to rotate. The rotating shaft 31 drives the first bevel gear 32 and the second bevel gear 33 to rotate. The first bevel gear 32 and the second bevel gear 33 drive the third bevel gear 35 to rotate. The third bevel gear 35 drives the threaded bolt 36 to rotate. The threaded bolt 36 drives the connecting plate 38 to move up and down, thereby moving the upper body 1. When the upper body 1 moves, the top plate 37 limits the upward movement of the upper body 1. When the doctor performs surgery, he drives the upper body by holding the handle 59. The upper tube 58, connecting tube 56, and L-tube 57 are moved. When the upper tube 58, connecting tube 56, and L-tube 57 are moved, they move on the hemispherical ball 54 through the connecting sleeve 55, thereby allowing the overall lighting mechanism 5 to move flexibly and drive the lighting lamp 591 to adjust its angle. When the lighting mechanism 5 needs to be cleaned and disassembled, the movable sleeve 53 and hemispherical ball 54 are pulled out from the movable hole 52 and connecting sleeve 55, and then the upper tube 58 is rotated so that the upper tube 58 is disengaged from the connecting tube 56, so that the L-tube 57 can be separated.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
