Technical Field
[0001] This application relates to the field of medical device technology, and in particular to a conveniently adjustable speculum. Background Technology
[0002] A speculum is an instrument used to dilate a woman's vagina during gynecological examinations. It typically has two blades, which open and close to dilate the vagina. During a gynecological examination, the speculum is used to dilate the vagina to a certain extent, allowing the doctor to perform examinations and procedures through the viewing opening.
[0003] Existing speculum requires the operator to constantly press the handle to keep the blades open for examination, which puts a strain on the operator's arm and hand, resulting in low practicality. Speculum with fixed blade expansion requires one hand to hold it while the other hand adjusts the locking device, such as the locking nut, to fix the blade position, thus requiring both hands to operate. This is cumbersome and inconvenient, making stable one-handed operation impossible. Therefore, this paper proposes a conveniently adjustable speculum that is easy to operate with one hand, is easy to adjust, safe, reliable, and highly practical. Utility Model Content

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0028] One preferred embodiment of this application, such as Figures 1 to 9As shown, a conveniently adjustable speculum includes an upper piece 1 and a lower piece 2. The upper piece 1 is rotatably mounted on the lower piece 2. The sides of the upper piece 1 and the lower piece 2 are engaged by an adjustment structure 3. The adjustment structure 3 allows the upper piece 1 to be locked and fixed after vertical adjustment of the gap between it and the lower piece 2, preventing vertical movement and thus better securing the adjusted upper piece 1. An adjustment member 12 is provided on the side of the upper piece 1, and the adjustment member 12 is engaged with the lower piece 2 by a locking structure 4. The locking structure 4 allows the adjustment member 12 to be locked and fixed after the upper piece 1 is rotated and expanded along its installation position, facilitating better operation and observation. During operation, the gap between the upper piece 1 and the lower piece 2 can be adjusted first to better suit the needs of different patients and medical staff. Then, the adjustment structure 3 can be driven to adjust the gap. Section 3 releases the lock on the upper piece 1, allowing it to move up and down to adjust the distance between the upper piece 1 and the lower piece 2. After adjustment, the adjustment structure 3 can be driven again to lock the adjusted upper piece 1 in place. The upper piece 1 and lower piece 2 can then be placed in the desired position. The locking structure 4 can be operated with the index or ring finger of one hand to release the lock on the adjusting member 12. The thumb of one hand can then drive the adjusting member 12 to rotate, causing the upper piece 1 to rotate at the installation position, thus separating and expanding the upper piece 1 and lower piece 2. The index or ring finger of one hand is then released, allowing the locking structure 4 to lock the adjusting member 12 again, preventing the adjusting rod 121 from rotating further. This ensures that the upper piece 1 remains stably expanded, facilitating better observation and operation by medical personnel and improving the practicality and convenience of the device.
[0029] In this embodiment, as Figure 2 , Figures 5 to 7 As shown, it can be understood that sliding grooves 21 are provided on both sides of the upper end of the lower piece 2 so that the upper piece 1 can slide up and down along the sliding grooves 21 for adjustment. A sliding rod 11 is provided on one side of the upper piece 1. The sliding rod 11 passes through the sliding groove 21 and is locked and fixed in the vertical direction by the adjustment structure 3. This ensures that after the upper piece 1 is adjusted up and down, the adjustment structure 3 locks and fixes the upper piece 1 in place without restricting the rotation of the sliding rod 11.
[0030] In this embodiment, as Figures 5 to 7As shown, the adjustment structure 3 includes an adjustment block 31 sleeved on the side of the sliding rod 11, and a pressing block 32 threaded onto the side of the adjustment block 31. The side of the pressing block 32 engages with the side of the lower piece 2. When adjusting the gap between the upper piece 1 and the lower piece 2, the pressing block 32 can be rotated to separate from the pressed lower piece 2, releasing the upper and lower locking of the sliding rod 11. The upper piece 1 can then be pulled, causing the sliding rod 11 on the upper piece 1 to slide up and down within the sliding groove 21 of the lower piece 2, thereby adjusting the upper piece 1 to suit the needs of different patients and medical staff. After adjustment, the pressing block 32 can be rotated again, allowing it to press against the side of the lower piece 2, locking the vertical movement of the sliding rod 11 and thus locking the upper piece 1 in the vertical direction.
[0031] In this embodiment, as Figures 1 to 4 , Figure 8 and Figure 9 As shown, the adjusting component 12 includes an adjusting rod 121 and a knob 122. One end of the adjusting rod 121 is installed on the side of the upper piece 1, and the other end of the adjusting rod 121 passes through the sliding groove 21 on the side of the lower piece 2 and extends out. The knob 122 is installed on the other end of the adjusting rod 121. The side of the adjusting rod 121 and the lower piece 2 are engaged by a locking structure 4. Therefore, during operation, only one hand is needed. The locking structure 4 can be adjusted by the index or ring finger of one hand, so that the locking structure 4 can release the locking of the adjusting rod 121. At this time, the adjusting rod 121 can be rotated, and then the thumb of one hand can... Rotating the knob 122 causes the adjusting rod 121 to rotate, which in turn causes the upper piece 1 to rotate at its installation position. When the upper piece 1 rotates, the adjusting structure 3 on the left side only locks the sliding rod 11 in the up-down direction, but does not lock or fix the rotation direction of the sliding rod 11. Thus, the sliding rod 11 can rotate within the sliding groove 21, allowing the upper piece 1 to rotate and slowly open and expand. This facilitates observation and operation by medical personnel, improving the practicality and convenience of the device. It is simple and convenient to operate, can be operated with one hand, has good practical effect, and is safe and reliable.
[0032] In this embodiment, as Figures 8 to 9 As shown, it can be understood that in order to lock and fix the adjusting rod 121 by the locking structure 4, a limiting plate 13 is sleeved on the side of the adjusting rod 121. The limiting plate 13 is slidably set on the side of the lower piece 2, so that the locking structure 4 will not rotate with the adjusting rod 121, but can move up and down with the upper piece 1, thereby facilitating better operation of the device and making it practical and convenient.
[0033] In this embodiment, as Figures 1 to 4 , Figures 6 to 9 As shown, the locking structure 4 includes a locking block 41 and slots 42. The locking block 41 is elastically disposed on the side of the limiting plate 13 by a torsion spring, and the slots 42 are circumferentially distributed on the side of the adjusting rod 121. The locking block 41 and multiple slots 42 cooperate with each other. During operation, the gap between the upper piece 1 and the lower piece 2 can be adjusted first to better accommodate the needs of different patients and medical staff. Then, by rotating the squeezing block 32, the squeezing block 32 is separated from the squeezing lower piece 2. At this time, the sliding rod 11 releases the upper and lower locking, and the upper piece 1 can be pulled to... The sliding rod 11 on the upper film 1 slides up and down within the sliding groove 21 of the lower film 2, thereby adjusting the upper film 1 to suit the needs of different patients and medical staff. After adjustment, the squeezing block 32 can be rotated again, so that the squeezing block 32 can fit against the side of the lower film 2, thereby locking and fixing the up and down movement of the sliding rod 11, and thus locking and fixing the up and down direction of the upper film 1. When expanding, it can be easily operated with only one hand, by elastically pressing the locking block 41 with the index or ring finger of one hand. This causes the side of the locking block 41 to extend out of the slot 42. At this time, the locking block 41 is not engaged with the slot 42, thus releasing the lock on the adjusting rod 121. At this time, the thumb of one hand can rotate the knob 122, which in turn drives the adjusting rod 121 to rotate. The rotation of the adjusting rod 121 drives the upper piece 1 to rotate at the installation position. When the upper piece 1 rotates, the adjustment structure 3 on the left side only locks the sliding rod 11 in the up and down direction, but does not lock or fix the rotation direction of the sliding rod 11. Thus, the sliding rod 11 can move in the sliding groove 21. The upper piece 1 can rotate inside, allowing it to slowly open and expand, facilitating observation and operation by medical personnel. After expansion, the locking block 41 can be released. Under the elastic reset of the torsion spring, the locking block 41 can re-insert into the slot 42, thus locking the adjustment rod 121 by engaging with the slot 42. This prevents the rotation of the upper piece 1 from being locked, thereby expanding and fixing the upper piece 1, improving the stability of the device during use. The operation is simple and convenient, can be operated with one hand, and is safe and reliable.
[0034] In this embodiment, as Figure 1 As shown, it can be understood that a handle 22 is provided on the side of the lower piece 2 for better handling of the device, thereby facilitating operation through the handle 22 and improving the convenience and ease of operation of the device.
[0035] In this embodiment, as Figure 1 , Figure 3 and Figure 4As shown, it should be noted that in order to make the knob 122 rotate more easily, anti-slip texture is provided on the side of the knob 122, so that medical staff can smoothly rotate the knob 122 with their thumb.
[0036] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
