Description

Technical Field

[0001] This invention patent relates to the field of medical examination instruments, and specifically to an adjustable cervical exposure speculum. Background Art

[0002] In the field of gynecological medicine, cervical examination is one of the common and important diagnostic methods. Traditional cervical speculums are usually designed in a relatively fixed manner, making it difficult to adapt to the cervical morphology and exposure requirements of different patients, which may cause discomfort or limited vision during the examination, affecting the doctor's diagnostic accuracy. In addition, for some special cases, such as patients with a deeper cervical position or abnormal morphology, traditional speculums are even more difficult to meet the examination requirements.

[0003] Although some existing speculums attempt to improve the above problems by adding adjustment functions, they often have complex structures, cumbersome operations, and limited adjustment effects, and cannot well meet the clinical needs. Therefore, developing an adjustable cervical exposure speculum with a simple structure, convenient operation, and wide adjustment range is of great significance for improving the comfort, accuracy, and efficiency of gynecological examinations.

[0004] Contents of the Invention Patent The purpose of this invention patent is to provide an adjustable cervical exposure speculum to solve the problems raised in the above background art.

[0005] To achieve the above purpose, this invention patent provides the following technical solution: An adjustable cervical exposure speculum, including a dilator and a regulator. The dilator includes semi - closed duckbill blades arranged obliquely and a connecting U - shaped frame connected to the semi - closed duckbill blades. The regulator includes a hinge assembly and a pulling assembly.

[0006] Further, the pulling assembly includes an L - shaped rod and a threaded screw rod. The L - shaped rod includes a long rod and a short rod. The threaded screw rod is arranged parallel to the long rod. The two ends of the threaded screw rod are respectively rotatably connected to the connecting U - shaped frame and the short rod. One section of the threaded screw rod penetrates through the short rod and is fixedly connected with a rotating handle.

[0007] Further, an adjusting slider is threadedly sleeved on the threaded screw rod. The adjusting slider is slidably and cooperatively connected with the long rod. The hinge assembly is connected to the adjusting slider and the connecting U - shaped frame.

[0008] Further, the hinge assembly includes an adjusting rod. A driving U - shaped frame is fixedly connected to the adjusting slider. One end of the driving U - shaped frame is rotatably and cooperatively connected to one end of the adjusting rod through a driving rotating shaft. The other section of the adjusting rod away from the adjusting slider is rotatably connected to a cooperating U - shaped frame. The two ends of the cooperating U - shaped frame are rotatably connected to a cooperating rotating shaft. The cooperating rotating shaft is fixedly connected to the connecting U - shaped frame.

[0009] Further, the semi - closed duckbill blade is fixedly and cooperatively connected to the connecting U - shaped frame, and the connecting U - shaped frame is rotationally and cooperatively connected to the end of the long rod away from the short rod through a connecting rotating shaft.

[0010] Compared with the prior art, the beneficial effects of the present invention for the invention patent are as follows: The adjustable cervical exposure speculum of the present invention significantly improves the comfort and diagnostic accuracy of gynecological examinations through a flexible adjustment mechanism. Its design simplifies the operation process, enabling medical staff to easily adjust the speculum to meet the needs of different patients and reduce patient discomfort. At the same time, a wider field of view helps to detect minor lesions and improve the diagnostic efficiency. In addition, the speculum also enhances the applicability, is suitable for various cervical morphologies, optimizes the patient examination experience, and improves the quality of medical services.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] Next, the technical solutions in the embodiments of the present invention patent will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention patent. Obviously, the described embodiments are only a part of the embodiments of the present invention patent, rather than all the embodiments. Based on the embodiments in the present invention patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention patent. In combination with the following embodiments, please refer to Figure 1 - Figure 2 : Embodiment 1: As Figure 1 - 2 shown, an adjustable cervical exposure speculum includes a dilator and a regulator. The dilator includes an inclined semi - closed duckbill blade 1 and a connecting U - shaped frame 2 connected to the semi - closed duckbill blade 1. The regulator includes a hinged assembly and a pulling assembly. The regulators are symmetrically arranged, and two symmetrically - arranged groups together form the cervical exposure speculum. By inserting the semi - closed duckbill blade 1 into the cervix and then adjusting the regulator to gradually open the cervix at the distal end of the semi - closed duckbill blade 1, the pain brought by the cervical exposure speculum to the patient during the examination can be reduced during the gradual opening process.

[0013] As Figure 1 - 2As shown in the figure, in this embodiment, the pulling assembly includes an L-shaped rod and a threaded lead screw 7. The L-shaped rod includes a long rod 4 and a short rod 5. The threaded lead screw 7 is arranged parallel to the long rod 4. The two ends of the threaded lead screw 7 are respectively rotatably connected to the connecting U-shaped frame 2 and the short rod 5. One section of the threaded lead screw 7 penetrates through the short rod 5 and is fixedly connected with a rotating handle 6. An adjusting slider 8 is sleeved on the threaded lead screw 7 in a threaded manner. The adjusting slider 8 is slidably and cooperatively connected with the long rod 4. The hinged assembly is connected between the adjusting slider 8 and the connecting U-shaped frame 2. By rotating the rotating handle 6, the adjusting slider 8 can be driven to move back and forth on the threaded lead screw 7. By using the adjusting slider 8 during the movement, the two semi-closed duckbill blades 1 are gradually pulled open through the hinged assembly to form an inspection space.

[0014] As Figure 1 - 2 shown in the figure, in this embodiment, the hinged assembly includes an adjusting rod 9. A driving U-shaped frame 10 is fixedly connected to the adjusting slider 8. One end of the driving U-shaped frame 10 is rotatably and cooperatively connected with one end of the adjusting rod 9 through a driving rotating shaft 11. The other section of the adjusting rod 9 away from the adjusting slider 8 is rotatably connected with a cooperating U-shaped frame 12. The two ends of the cooperating U-shaped frame 12 are rotatably connected to a cooperating rotating shaft 13. The cooperating rotating shaft 13 is fixedly connected to the connecting U-shaped frame 2. During the movement of the adjusting slider 8, the adjusting rod 9 is pulled to move towards the side away from the connecting U-shaped frame 2. The angle change between the adjusting rod 9 and the driving U-shaped frame 10 and the angle change between the adjusting rod 9 and the cooperating U-shaped frame 12 gradually change as the connecting U-shaped frame 2 is pulled to rotate. The adjusting rod 9, the driving U-shaped frame 10, the cooperating U-shaped frame 12, and the cooperating rotating shaft 13 play an auxiliary supporting role in pulling the connecting U-shaped frame 2 to rotate by the adjusting rod 9.

[0015] As Figure 1 - 2 shown in the figure, in this embodiment, the semi-closed duckbill blade 1 is fixedly and cooperatively connected with the connecting U-shaped frame 2. The connecting U-shaped frame 2 is rotatably and cooperatively connected with the end of the long rod 4 away from the short rod 5 through a connecting rotating shaft 3. The connection between the connecting U-shaped frame 2 and the long rod 4 through the connecting rotating shaft 3 facilitates the connecting U-shaped frame 2 to pull the semi-closed duckbill blade 1 to rotate and gradually expand the cervical inspection opening.
