Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a special illuminated speculum for obese individuals with a side leakage prevention mesh support. Background Technology

[0002] A speculum is one of the most basic and commonly used medical instruments in gynecological examinations. Its main function is to dilate the vaginal wall to expose the cervix, facilitating visual examination, sampling, biopsy, or minor surgical procedures. Traditional speculum typically consists of an upper and lower blade, manually opened using a mechanical lever principle. When the blades are opened, loose or thickened vaginal walls can easily overflow into the operating space of the upper and lower blades. This overflowing tissue can severely obstruct the doctor's view, obscuring the cervix and vaginal wall that need to be observed. The doctor must repeatedly adjust the position and angle of the speculum or reinsert it, which not only prolongs the examination time and increases patient discomfort but also interferes with the accuracy of sampling sites, leading to misdiagnosis. A specially designed illuminated speculum for obese patients addresses these problems. Summary of the Invention

[0003] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0004] To address the technical problems mentioned in the background section above, some embodiments of this application provide a special illuminated speculum for obese individuals with an anti-leakage mesh support, comprising a lower leaf, an upper leaf movably disposed on the lower leaf, an illumination mechanism disposed on the lower leaf, a drive mechanism disposed on the lower leaf for driving the upper leaf to move, and a blocking mechanism disposed on the lower leaf; the blocking mechanism includes a blocking mesh support fixed at one end on the lower leaf, a fixing rod fixed on the lower leaf, a torsion spring fixed at both ends on the blocking mesh support and the fixing rod respectively, and a first clearance groove disposed inside the upper leaf; the blocking mesh support is disposed through the first clearance groove.

[0005] Specifically, the cross-sections of both the upper and lower leaves are arc-shaped; the radius of the arc is 4-6 cm.

[0006] Specifically, both the upper and lower leaves are made of medical-grade PP material with a thickness of 1.2-1.5mm.

[0007] Specifically, the barrier net holder includes PET mesh fabric and silicone edging fixed on both sides of the PET mesh fabric.

[0008] Specifically, the lighting mechanism includes a first slide groove disposed in the lower leaf, a screw rotatably disposed in the first slide groove, a second slider movably disposed in the first slide groove and threadedly engaged with the screw, a lighting lamp rotatably disposed on the second slider, a first knob fixedly disposed at one end of the screw, and a rotating component disposed on the lower leaf for driving the lighting lamp to rotate.

[0009] Specifically, the rotating assembly includes a first rotating shaft rotatably disposed on the lower leaf, a second sliding groove disposed on the first rotating shaft, a second sliding block movably disposed in the second sliding groove, and a second clearance groove disposed on the first sliding block; the lighting lamp is fixedly disposed on the second sliding block; the second rotating shaft is rotatably disposed on the first sliding block.

[0010] Specifically, the rotating assembly also includes a first rubber friction plate fixedly disposed inside the second clearance groove and a second rubber friction plate fixedly disposed on the second slider.

[0011] Specifically, the drive mechanism includes a support rod fixed on the upper blade, a rack fixed on the upper blade, a connecting rod with its two ends fixed on the support rod and the rack respectively, a gear rotatably mounted on the lower blade and meshing with the rack, a second rotating shaft fixed on the gear, and a second knob fixed on the second rotating shaft.

[0012] Specifically, multiple elastic rubber balls are fixedly mounted on the second rotating shaft; multiple arc-shaped grooves are provided on the lower leaf.

[0013] The beneficial effects of this invention are: (1) Using this speculum, the vaginal sidewall can be actively and in real time blocked from entering the gap between the upper and lower lobes, solving the problem that obese patients often experience vaginal sidewalls embedding into the temporal part of the speculum, obstructing their view and operating space when using traditional speculum. During examination and operation, doctors can more stably and fully expose the area to be examined without repeatedly adjusting or clearing the field of view, and can focus on observing key areas such as the cervix and vaginal wall, improving examination efficiency and diagnostic accuracy.

[0014] (2) The position and angle of the lighting can be adjusted independently, which can illuminate areas such as the cervix that are difficult to be fully illuminated by traditional fixed light sources, avoiding misdiagnosis or missed diagnosis caused by shadows. Doctors can finely adjust the light with one hand during the operation without the need for additional light sources. Attached Figure Description

[0022] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1-9 As shown, the obese-type special illumination speculum with anti-leakage mesh support of the present invention includes a lower leaf 1, an upper leaf 2 movably disposed on the lower leaf 1, an illumination mechanism 3 disposed on the lower leaf 1, a driving mechanism 4 disposed on the lower leaf 1 for driving the upper leaf 2 to move, and a blocking mechanism 5 disposed on the lower leaf 1; the blocking mechanism 5 includes a blocking mesh support 51 fixed at one end on the lower leaf 1, a fixing rod 52 fixed on the lower leaf 1, a torsion spring 53 fixed at both ends on the blocking mesh support 51 and the fixing rod 52 respectively, and a first clearance groove 54 disposed inside the upper leaf 2; the blocking mesh support 51 is disposed through the first clearance groove 54.

[0024] When using this speculum, turn on the lighting mechanism 3, insert the speculum into the patient's vagina, and the drive mechanism 4 drives the upper leaf 2 to move, supporting the patient's vagina. During the movement of the upper leaf 2, the blocking net 51 moves within the first clearance groove 54, pulling the torsion spring 53. The torsion spring 53 generates a reaction force, tightening the blocking net 51. When medical staff adjust the distance between the upper leaf 2 and the lower leaf 1, the blocking net 51, which is always in a taut state, can actively and in real time prevent the vaginal sidewall from entering the gap between the upper leaf 2 and the lower leaf 1. This solves the problem of obese patients using traditional speculums where the vaginal sidewall easily gets embedded inside the speculum, obstructing the view and operating space. When the doctor places the upper leaf 2 and the lower leaf 1 together, the torsion spring 53 can promptly retract the blocking net 51 into the lower leaf, preventing the blocking net 51 from being trapped between the upper leaf 2 and the lower leaf 1, scraping against the patient's vaginal wall, and causing mucosal damage. During examinations and procedures, doctors can more stably and fully expose the areas to be examined without repeatedly adjusting or clearing the field of vision. They can focus on observing key areas such as the cervix and vaginal walls, improving examination efficiency and diagnostic accuracy.

[0025] Specifically, the cross-sections of the upper leaf 2 and the lower leaf 1 are both arc-shaped; the radius of the arc is 4-6 cm.

[0026] The radius of the arc shape is more suitable for obese patients, as it can better fit their physiological structure and reduce mechanical pressure and discomfort.

[0027] Specifically, both the upper leaf 2 and the lower leaf 1 are made of medical-grade PP material with a thickness of 1.2-1.5mm.

[0028] Specifically, the blocking net holder 51 includes a PET mesh fabric 511 and silicone edging 512 fixed on both sides of the PET mesh fabric 511.

[0029] The silicone edging 512 makes the edges of the PET mesh fabric 511 smoother, preventing it from damaging the mucosa.

[0030] Specifically, the lighting mechanism 3 includes a first slide groove 31 disposed in the lower leaf 1, a screw 32 rotatably disposed in the first slide groove 31, a second slider 363 movably disposed in the first slide groove 31 and threadedly engaged with the screw 32, a lighting lamp 34 rotatably disposed on the second slider 363, a first knob 35 fixedly disposed at one end of the screw 32, and a rotating component 36 disposed on the lower leaf 1 for driving the lighting lamp 34 to rotate.

[0031] Specifically, the rotating assembly 36 includes a first rotating shaft 361 rotatably disposed on the lower leaf 1, a second sliding groove 362 disposed on the first rotating shaft 361, a second sliding block 363 movably disposed in the second sliding groove 362, and a second clearance groove 364 disposed on the first sliding block 33; the lighting lamp 34 is fixedly disposed on the second sliding block 363; and the second rotating shaft 45 is rotatably disposed on the first sliding block 33.

[0032] Specifically, the rotating assembly 36 further includes a first rubber friction plate 365 fixedly disposed inside the second clearance groove 364 and a second rubber friction plate 366 fixedly disposed on the second slider 363.

[0033] When a doctor needs to observe a specific area inside the vagina, turning the first knob 35 rotates the screw 32, which in turn moves the first slider 33 within the first groove 31, simultaneously moving the second slider 363 within the second groove 362. The illumination lamp 34 moves accordingly. Once the desired position is reached, rotating the first shaft 361 rotates the second slider 363, which in turn rotates the illumination lamp 34. Friction is generated between the first rubber friction plate 365 and the second rubber friction plate 366 to prevent accidental rotation of the illumination lamp 34. The illumination lamp 34 can move and rotate within the lower leaf 1, and its position and angle can be independently adjusted. It can illuminate areas such as the cervix that are difficult to fully illuminate with traditional fixed light sources, avoiding misdiagnosis or missed diagnosis caused by shadows. The doctor can fine-tune the light with one hand during the operation without the need for an additional light source.

[0034] Specifically, the drive mechanism 4 includes a support rod 41 fixedly mounted on the upper leaf 2, a rack 42 fixedly mounted on the upper leaf 2, a connecting rod 43 with its two ends fixedly mounted on the support rod 41 and the rack 42 respectively, a gear 44 rotatably mounted on the lower leaf 1 and meshing with the rack 42, a second rotating shaft 45 fixedly mounted on the gear 44, and a second knob 46 fixedly mounted on the second rotating shaft 45.

[0035] Specifically, a plurality of elastic rubber balls 47 are fixedly provided on the second rotating shaft 45; a plurality of arc-shaped grooves 48 are provided on the lower leaf 1.

[0036] Turning the second knob 46 rotates the gear 44, causing the rack 42, which meshes with the gear 44, to move, thus moving the upper leaf 2 up and down. The elastic rubber ball 47 engages with the arc-shaped groove 48, allowing the speculum to remain open after the upper leaf 2 reaches the appropriate position, eliminating the need for the doctor to hold it continuously. This facilitates sampling, biopsy, and other procedures, greatly simplifying subsequent examinations. The elastic rubber ball 47 and the arc-shaped groove 48 provide a pre-tightening force, which, together with the pressure of the patient's vagina on the upper leaf 1, resists the doctor's force in adjusting the position of the upper leaf 1. In other words, the pre-tightening force amplifies the pressure force, making it easier for the doctor to determine the appropriate position of the upper leaf and preventing excessive force from increasing patient discomfort.

[0037] In summary, the present invention, through the blocking net holder 51, ensures that the doctor's field of vision is clear enough when using the speculum, which is beneficial for clinical operations such as sampling, biopsy, and minor surgery, improving work efficiency while reducing patient discomfort.
