Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adjustable speculum. Background Technology

[0002] A speculum is an essential tool in gynecological examinations. It helps doctors observe the health of the cervix, vagina, uterus, and other parts of the body. In family planning surgeries, speculum is also often used to dilate the vagina to facilitate surgical procedures. In some cases requiring vaginal surgery, speculum can serve as a surgical aid to help doctors perform the procedures more effectively. Speculum has an adjustable opening angle to accommodate different patients' body structures and examination needs.

[0003] Existing adjustable speculum does not have a specimen bag at the end of the dilator blade. Medical staff directly collect specimens from inside the vagina using sampling instruments. At the same time, the length of the speculum's dilator blade is fixed, and the working length is consistent in different vaginas. When the staff opens the dilator blade by using the handle, they need to apply continuous force to the handle to keep it in a certain position until the medical staff completes the specimen collection.

[0004] These adjustable speculum devices have some problems. For example, the end of the dilator blade does not have a specimen pocket, so sometimes the specimen can easily fall out of the vagina when retrieving it, which can lead to missed specimens, especially small specimens. The length of the dilator blade is fixed, which cannot effectively meet the needs of different vaginas of different patients. It also affects the comfort of patients. It is difficult for staff to continuously apply force to the handle, which increases the workload of medical staff and makes it inconvenient for them to perform other operations. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an adjustable speculum that can adapt to different vaginas of different people, while enabling the two handles to quickly and stably lock in position at different opening degrees. The quick-release specimen bag can effectively prevent specimens from being missed, and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable speculum, including a handle, with the middle of two handles rotatably connected, and also including a limiting mechanism and a collecting mechanism;

[0007] Limiting mechanism: It includes a limiting groove, a limiting cylinder, an adjusting seat, a limiting handle, and a limiting frame. The limiting grooves are symmetrically arranged at the lower ends of the two handles opposite to their outer surfaces. Each limiting groove is provided with a limiting cylinder. The front end of the left limiting cylinder is rotatably connected to the adjusting seat. The interior of the adjusting seat is rotatably connected to the left end of the limiting handle. The front end of the right limiting cylinder is rotatably connected to the limiting frame. The limiting handle is located inside the limiting frame. The rear inner wall of the limiting frame is fixedly connected with evenly distributed ratchet teeth. The rear end of the limiting handle is provided with evenly distributed ratchet grooves. The ratchet teeth are all installed in conjunction with the longitudinally adjacent ratchet grooves.

[0008] Collection mechanism: It is located at the front end of the handle on the left side;

[0009] Among them, each of the handles has an expansion leaf inserted into the socket at the upper end of the rear surface. While adapting to different vaginas of different people, it can quickly and stably lock the two handles at different opening degrees. The quick-pack specimen bag can effectively prevent specimens from being missed.

[0010] Furthermore, the limiting mechanism also includes a screw, which is threadedly connected to the front end of the limiting frame. A top plate is fixedly connected to the rear end of the screw, and a knob is fixedly connected to the front end of the screw. The limiting groove is provided with evenly distributed toothed grooves, and the relative inner surfaces of the two limiting cylinders are provided with evenly distributed teeth. The teeth are installed in conjunction with the radially adjacent toothed grooves to lock the position of the limiting handle, thereby locking the positions of the two limiting cylinders.

[0011] Furthermore, the limiting mechanism also includes a slide rod and a guide cylinder. The slide rod is rotatably connected to the rear end of the right limiting cylinder, and the guide cylinder is rotatably connected to the rear end of the left limiting cylinder. The outer surface of the slide rod and the interior of the guide cylinder are slidably connected to provide guidance for the relative movement of the limiting cylinder.

[0012] Furthermore, the collection mechanism includes a connecting seat and a specimen bag. The connecting seat is located at the front end of the handle on the left side, and a specimen bag is provided inside the connecting seat to prevent specimens from being missed.

[0013] Furthermore, the collection mechanism also includes a locking post and a spring plate. The locking post is symmetrically fixedly connected to the upper end of the two handles opposite to the outer surface. The spring plate is symmetrically fixedly connected to the rear end of the connecting seat. Two vertically adjacent spring plates form a spring clip. The spring clips are all installed in conjunction with the longitudinally adjacent locking posts to facilitate the installation of the specimen bag.

[0014] Furthermore, it also includes supports, which are fixedly connected to the front and rear ends of the right handle respectively. The middle part of the support and the middle part of the left handle are rotatably connected by a connecting shaft. The middle part of the right handle is provided with a relief groove, which is located between the two supports. The lower ends of the opposite inner surfaces of the two handles are fixedly connected with elastic plates two. A pin is provided between the upper ends of the two elastic plates two to provide rotational support for the handle and at the same time prevent the handle from rotating too fast.

[0015] Furthermore, it also includes rib grooves, which are evenly distributed in the middle of the two handles opposite to the outer surface, to prevent slippage when the person holds the handle.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjustable speculum has the following advantages:

[0017] 1. It can select different lengths of dilator blades according to the different vaginal conditions of different people to perform vaginal dilation, which improves the convenience and comfort of using the speculum.

[0018] 2. The limiting cylinders are in close contact with the corresponding limiting grooves. The cylindrical design of the limiting cylinders can meet the fitting requirements of the limiting grooves in different positions. At the same time, the top plate limits the limiting handles under the action of the screw, so that the ratchet teeth are stably inserted into the corresponding ratchet grooves. This enables the two handles to be quickly and stably locked in different opening degrees, without the need for personnel to apply force to the two handles. It also facilitates the doctor's sampling of the markings.

[0019] 3. Two spring plates form a spring clamp to quickly and stably hold the locking post, thereby enabling the specimen bag to be quickly installed in the corresponding position, avoiding specimen leakage caused by specimens of different sizes slipping out of the vagina.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This embodiment provides a technical solution: an adjustable speculum, including a handle 1, two handles 1 rotatably connected at the middle, and also including a limiting mechanism 2 and a collecting mechanism 3;

[0027] Limiting mechanism 2 includes a limiting groove 21, a limiting cylinder 22, an adjusting seat 23, a limiting handle 24, and a limiting frame 25. The limiting grooves 21 are symmetrically arranged at the lower ends of the two handles 1 facing away from their outer surfaces. Each limiting groove 21 has a limiting cylinder 22 inside. The front end of the left limiting cylinder 22 is rotatably connected to the adjusting seat 23, and the interior of the adjusting seat 23 is rotatably connected to the left end of the limiting handle 24. The front end of the right limiting cylinder 22 is rotatably connected to the limiting frame 25. The limiting handle 24 is located inside the limiting frame 25. The limiting frame 25... The rear inner wall of the 5 is fixedly connected with evenly distributed ratchet teeth. The rear end of the limiting handle 24 is provided with evenly distributed ratchet grooves. The ratchet teeth are all installed in conjunction with the longitudinally adjacent ratchet grooves. The limiting mechanism 2 also includes a screw 26, which is threadedly connected to the front end of the limiting frame 25. The rear end of the screw 26 is fixedly connected to a top plate, and the front end of the screw 26 is fixedly connected to a knob. The interior of the limiting groove 21 is provided with evenly distributed tooth grooves. The opposing inner surfaces of the two limiting cylinders 22 are all provided with evenly distributed teeth, which are all radially adjacent to each other. The toothed grooves are fitted together. The limiting mechanism 2 also includes a slide rod 27 and a guide cylinder 28. The slide rod 27 is rotatably connected to the rear end of the right limiting cylinder 22, and the guide cylinder 28 is rotatably connected to the rear end of the left limiting cylinder 22. The outer surface of the slide rod 27 and the interior of the guide cylinder 28 are slidably connected. The limiting cylinders 22 are moved to positions corresponding to the horizontal level of the limiting groove 21, and then the two limiting cylinders 22 are moved towards each other. The outer surface of the slide rod 27 slides inside the guide cylinder 28, providing guidance and limiting for the movement of the limiting cylinders 22. Simultaneously, the limiting handle 24 moves inside the limiting frame 25. When the teeth of the limiting cylinder 22 are tightly engaged with the teeth of the adjacent limiting groove 21, the screw 26 is rotated by the knob. The screw 26 moves backward under the action of the limiting frame 25, thereby driving the top plate to move backward. The top plate applies a backward force to the limiting handle 24, causing the limiting handle 24 to rotate backward. When the ratchet inside the limiting frame 25 is tightly engaged with the ratchet groove of the limiting handle 24, the knob is stopped from being rotated, and the two limiting cylinders 22 lock the position of the handle 1.

[0028] Collection mechanism 3: It is located at the front end of the handle 1 on the left side. The collection mechanism 3 includes a connecting seat 33 and a specimen bag 34. The connecting seat 33 is located at the front end of the handle 1 on the left side. The specimen bag 34 is provided inside the connecting seat 33. The collection mechanism 3 also includes a locking pin 31 and a spring plate 32. The locking pin 31 is symmetrically fixedly connected to the upper end of the two handles 1 opposite to the outer surface. The spring plate 32 is symmetrically fixedly connected to the rear end of the connecting seat 33. Two vertically adjacent spring plates 32 form a spring clip. The spring clips are installed in conjunction with the vertically adjacent locking pins 31. The connecting seat 33 is moved to the designated position, and then the connecting seat 33 is moved backward so that the spring clip formed by the two vertically adjacent spring plates 32 is engaged with the vertically adjacent locking pins 31, thereby fixing the position of the connecting seat 33 and finally fixing the position of the specimen bag 34. When a specimen slides out of the vagina, the marking bag 34 collects the slid-out specimen to avoid missing specimens.

[0029] Among them: an expansion leaf 4 is inserted into the socket at the upper end of the rear surface of the handle 1. According to the patient's actual body structure and examination needs, the expansion leaf 4 of the corresponding length is selected. The expansion leaf 4 and the speculum itself are disinfected. Then the expansion leaf 4 is symmetrically inserted into the upper end of the rear surface of the two handles 1.

[0030] The system includes supports 5, which are fixedly connected to the front and rear ends of the right handle 1. The middle of the support 5 and the middle of the left handle 1 are rotatably connected by a connecting shaft. The middle of the right handle 1 is provided with a clearance groove 6, which is located between the two supports 5. When the left handle 1 is rotated, the clearance groove 6 provides clearance space for the left handle 1. The lower ends of the inner surfaces of the two handles 1 are fixedly connected with elastic pieces 7. A pin is provided between the upper ends of the two elastic pieces 7. The dilator 4 is slowly inserted into the vagina through the handle 1. When the dilator 4... 4. When the desired position is reached, stop moving handle 1 and apply force to both handles 1, causing them to rotate in opposite directions around the central axis of the connecting shaft, thereby opening the dilator leaf 4. At the same time, the spring plates 7 support each other under the action of the pin, generating opposite elastic forces on the force transmitted to the handle 1. Under the buffer protection of the elastic force, the opening speed of the dilator leaf 4 is reduced to prevent the dilator leaf 4 from moving too fast. The dilator leaf 4 applies force to the vaginal wall, thereby achieving vaginal dilation. When the vagina is dilated to the desired state, stop increasing the force applied to the handle 1.

[0031] It also includes rib grooves 8, which are evenly distributed in the middle of the two handles 1 opposite to each other on the outer surface. The rib grooves 8 increase the friction between the handles 1 and the hand.

[0032] The working principle of the adjustable speculum provided by this utility model is as follows: During operation, the operator first selects the appropriate length of the dilation blade 4 according to the patient's actual body structure and examination needs. The dilation blade 4 and the speculum itself are then disinfected. The dilation blade 4 is then symmetrically inserted into the upper end of the rear surface of the two handles 1. The operator then moves the connecting seat 33 to the designated position and moves it backward so that the spring clip formed by the two vertically adjacent spring plates 32 engages with the longitudinally adjacent locking post 31, thereby fixing the position of the connecting seat 33 and ultimately fixing the position of the specimen bag 34. The operator slowly inserts the dilator 4 into the vagina through handle 1. When the dilator 4 reaches the desired position, the operator stops moving handle 1 and applies force to both handles 1, causing them to rotate in opposite directions around the central axis of the connecting shaft. This opens the dilator 4. Simultaneously, spring plates 7, supported by the pin, generate opposing elastic forces on the force transmitted from handle 1. This elastic force buffers and reduces the opening speed of the dilator 4, preventing it from moving too quickly. The dilator 4 applies force to the vaginal wall, thus dilating the vagina. When the vagina is dilated to the desired state, the operator stops applying force. A large force is applied to handle 1, and then the person moves the limiting cylinders 22 to positions corresponding to the horizontal level of the limiting grooves 21. (The limiting mechanism 2 is an independent structure during the adjustment of the two handles 1. When the two handles 1 are adjusted to the appropriate degree, that is, when the vagina is dilated to the required state, the limiting mechanism 2 is used to limit and fix the lower ends of the two handles 1 opposite to their outer surfaces.) Then the person moves the two limiting cylinders 22 towards each other. The outer surface of the slide rod 27 slides inside the guide cylinder 28, providing guidance and limiting for the movement of the limiting cylinders 22. At the same time, the limiting handle 24 moves inside the limiting frame 25. When the limiting cylinders 22... When the teeth of the device are tightly engaged with the inner grooves of the adjacent transverse limiting grooves 21, the operator rotates the screw 26 by turning the knob. The screw 26 moves backward under the action of the limiting frame 25, which in turn drives the top plate to move backward. The top plate applies a backward force to the limiting handle 24, causing the limiting handle 24 to rotate backward. When the ratchet inside the limiting frame 25 is tightly engaged with the ratchet groove of the limiting handle 24, the operator stops turning the knob. The two limiting cylinders 22 lock the position of the handle 1. Then the operator performs the test using medical instruments. When a specimen slips out of the vagina, the marking bag 34 collects the slipped specimen to avoid missing any specimens.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
