Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a vaginal speculum. Background Technology

[0002] During a total hysterectomy, the removed uterus is usually taken out through the vagina. However, while the vagina is elastic, its elasticity is limited. If the patient's uterus is too large, it cannot be removed directly from the vaginal opening.

[0003] Currently, the vaginal retractor is used clinically. Two vaginal retractors are used to open the vaginal wall, exposing the field of vision while protecting the vaginal wall. Then, the uterus is clamped and pulled outward while the uterus is cut into pieces or a strip with a scalpel and removed. However, the vaginal retractor provides limited exposure and cannot effectively protect the vaginal wall, which may cause some damage to the patient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a vaginal speculum to solve the problem that existing vaginal retractors have limited exposure and cannot adequately protect the vaginal wall, potentially causing damage to the patient.

[0005] To achieve the above objectives, this utility model provides a vaginal speculum, comprising: an elastic sleeve, a telescopic sleeve assembly, a fixing assembly, and an expansion assembly. The elastic sleeve is fitted over the outside of the telescopic sleeve assembly. The expansion assembly is used to enlarge the telescopic sleeve assembly. The fixing assembly is detachably installed at one end of the telescopic sleeve assembly and is used to fix the telescopic sleeve assembly. A locking block assembly for locking onto the vaginal stump is provided at the end of the telescopic sleeve assembly away from the fixing assembly.

[0006] This setup, by placing the elastic sleeve over the outside of the telescopic sleeve assembly, then using the expansion component to expand the telescopic sleeve assembly, and finally using the fixing component to fix the size of the inner diameter of the telescopic sleeve assembly, achieves the effect of protecting the patient's vaginal wall, while maximizing the expansion of the patient's vagina without obstructing the doctor's view.

[0007] Furthermore, the telescopic sleeve assembly is configured as multiple sets of arc-shaped plates; the arc-shaped plates include a first arc-shaped plate, a second arc-shaped plate, and a third arc-shaped plate, the first arc-shaped plate being slidably connected within the second arc-shaped plate, and the second arc-shaped plate being slidably connected within the third arc-shaped plate; one side of the third arc-shaped plate is fixedly connected to one side of an adjacent set of the first arc-shaped plates.

[0008] Furthermore, the expansion assembly includes an expansion airbag and a pressing airbag. One end of the pressing airbag is fixedly connected to a Y-shaped tube, and an air inlet valve and an air outlet valve are respectively installed on the two branches of the Y-shaped tube. The other end of the pressing airbag is fixedly connected to the expansion airbag for expanding the telescopic sleeve assembly through a connecting tube.

[0009] Furthermore, the fixing component includes a first open ring and a second open ring. One end of the first open ring is fixedly connected to the second open ring, and the other end has a plurality of first fixing through holes. One end of the second open ring has a sliding groove, and one end of the first open ring is slidably connected to the second open ring through the sliding groove. The end of the second open ring near the sliding groove has a second fixing through hole, and a fixing rod is detachably connected in the second fixing through hole. The fixing rod is used to fix the first open ring and the second open ring.

[0010] Furthermore, the locking block assembly includes a locking block, a rotating shaft, a torsion spring, and a wire. The rotating shaft is fixedly installed at one end of the third arc-shaped plate. The torsion spring is sleeved on the rotating shaft, with one end of the torsion spring fixedly connected to the third arc-shaped plate and the other end of the torsion spring fixedly connected to the locking block. The wire for pulling the locking block to rotate is fixedly connected to the locking block, and the locking block rotates around the central axis of the rotating shaft. A conduit for protecting the wire is fixedly installed on the inner side of the third arc-shaped plate, and the free end of the wire extends through the conduit out of the third arc-shaped plate away from the locking block.

[0011] Furthermore, an elastic protective layer is fixedly connected between the card block and the third arc-shaped plate.

[0012] Furthermore, one end of the card block is fixedly connected to a limit buckle, and a pocket is detachably connected to the limit buckle.

[0013] The beneficial effects of this embodiment are as follows:

[0014] 1. By placing the elastic sleeve on the outside of the telescopic sleeve assembly, then using the expansion component to expand the telescopic sleeve assembly, and finally using the fixing component to fix the size of the inner diameter of the telescopic sleeve assembly, the effect of protecting the patient's vaginal wall is achieved, while expanding the patient's vagina as much as possible without obstructing the doctor's view.

[0015] 2. By pressing the airbag to increase its diameter, the telescopic sleeve assembly can be expanded outwards slowly and evenly, which can reduce the patient's pain during vaginal dilation.

[0016] 3. By loosening the line, the locking block rotates outward under the elastic deformation of the torsion spring, opening up and locking onto the vaginal stump of the patient, thus fixing the telescopic sleeve assembly and preventing it from slipping out of the patient's vagina due to friction during operation.

[0026] Please see Figure 1-2 This utility model provides an embodiment of a vaginal speculum, comprising: an elastic sleeve 1, a telescopic sleeve assembly 2, a fixing assembly 3, and an expansion assembly. The elastic sleeve 1 is fitted over the outside of the telescopic sleeve assembly 2, and the elastic sleeve 1 can expand and contract with the telescopic sleeve assembly 2 to protect the patient and prevent the telescopic sleeve assembly 2 from directly contacting the patient's vaginal tissue, i.e., to prevent the doctor from scratching the patient's vaginal wall during the operation. The expansion assembly is used to expand the telescopic sleeve assembly 2. The fixing assembly 3 is detachably installed at one end of the telescopic sleeve assembly 2. The fixing assembly 3 is used to fix the telescopic sleeve assembly 2. When the telescopic sleeve assembly 2 expands under the action of the expansion assembly, the fixing assembly 3 is used to fix the telescopic sleeve assembly 2 in its expanded state, making it easy to remove the expansion assembly; at the same time, it prevents the telescopic sleeve assembly 2 from contracting after leaving the expansion assembly, which would affect the doctor's operation.

[0027] Please see Figure 1 In this embodiment, the elastic sleeve 1 can be made of elastic latex material, which has excellent elasticity and fit, can fit closely to the body parts, provide sufficient flexibility and sensitivity, and has good antibacterial properties, which can effectively block the spread of bacteria and viruses.

[0028] Please see Figure 1 In this embodiment, the telescopic sleeve assembly 2 is configured as multiple sets of arc-shaped plates, optionally four sets; each arc-shaped plate includes a first arc-shaped plate 22, a second arc-shaped plate 21, and a third arc-shaped plate 20. The first arc-shaped plate 22 is slidably connected inside the second arc-shaped plate 21, and the second arc-shaped plate 21 is slidably connected inside the third arc-shaped plate 20; one side of the third arc-shaped plate 20 is fixedly connected to one side of the adjacent set of first arc-shaped plates 22. In use, the telescopic sleeve assembly 2 is slowly expanded outward by the expansion component, that is, the second arc-shaped plate 21 slides out of the third arc-shaped plate 20 and the first arc-shaped plate 22 slides out of the second arc-shaped plate 21 by the expansion component, thereby achieving the effect of expanding the diameter, and thus achieving the purpose of expanding the patient's vagina.

[0029] Please see Figure 1In this embodiment, the first arc plate 22, the second arc plate 21 and the third arc plate 20 can all be made of metal to prevent the medical device from scratching the elastic sleeve 1 or even the patient's vaginal wall during the operation.

[0030] Please see Figure 5 In this embodiment, the expansion assembly includes an expansion airbag 6 and a pressing airbag 61. The expansion airbag 6 can be a sphere. One end of the pressing airbag 61 is fixedly connected to a Y-shaped tube 62, and an air inlet valve 63 and an air outlet valve 64 are respectively installed on the two branches of the Y-shaped tube 62. The other end of the pressing airbag 61 is fixedly connected to the expansion airbag 6 for expanding the telescopic sleeve assembly through a connecting tube. In use, the expansion airbag 6 is placed inside the telescopic sleeve assembly 2, and then the air inlet valve 63 is opened. The pressing airbag 61 is manually pressed to inflate the expansion airbag 6, so that its diameter gradually increases, thereby pushing the third arc plate 20 outward. This causes the second arc plate 21 to slide out of the third arc plate 20, and the first arc plate 22 to slide out of the second arc plate 21, thereby expanding the diameter of the telescopic sleeve assembly 2 and thus expanding the patient's vagina. After the dilation is completed, the fixing component is placed inside the shrinking sleeve component 2 and fixed in place. Then, the air inlet valve 63 is closed, the air outlet valve 64 is opened, and the air bladder 61 is manually pressed to expel air from the dilation air bladder 6, gradually reducing its diameter, thus allowing the dilation air bladder 6 to be removed for easier subsequent operations by the doctor. In actual use, the dilation component can be placed in a position easily accessible to the doctor, facilitating the use of the expandable sleeve component 2. Simultaneously, by slowly and evenly expanding the expandable sleeve component 2 outwards, the patient's pain during vaginal dilation can be reduced.

[0031] Please see Figure 2In this embodiment, the fixing component 3 includes a first open ring 31 and a second open ring 30. One end of the first open ring 31 is fixedly connected to the second open ring 30, and the other end is provided with a plurality of first fixing through holes 32. One end of the second open ring 30 is provided with a sliding groove, and one end of the first open ring 31 is slidably connected to the second open ring 30 through the sliding groove. The end of the second open ring 30 near the sliding groove is provided with a second fixing through hole, and a fixing rod 33 is detachably connected in the second fixing through hole. The fixing rod 33 is used to fix the first open ring 31 and the second open ring 30. Before use, the size of the ring formed by the first open ring 31 and the second open ring 30 can be adjusted by the cooperation of the first fixing through hole 32, the second fixing through hole and the fixing rod 33, so that it can be directly installed into the telescopic sleeve component 2 and abut against the first arc plate 22, the second arc plate 21 and the third arc plate 20, thereby achieving the effect of fixing the diameter of the telescopic sleeve component 2, which is convenient for doctors to operate later. In actual use, the fixing component can also be set as multiple rings of different diameters. When in use, a ring of appropriate diameter is selected according to actual needs and inserted into the telescopic sleeve component 2, abutting against the first arc plate 22, the second arc plate 21 and the third arc plate 20, thereby achieving the effect of fixing the diameter of the telescopic sleeve component 2, which is convenient for doctors to operate later.

[0032] Please see Figure 1 In this embodiment, the end of the telescopic sleeve assembly 2 away from the fixing assembly 3 is provided with a locking block assembly for locking onto the vaginal stump. Multiple locking block assemblies are provided, and four are optional.

[0033] Please see Figure 3-4 and Figure 6 In this embodiment, the locking block assembly includes a locking block, a rotating shaft 43, a torsion spring 44, and a wire 45. The rotating shaft 43 is fixedly installed at one end of the third arc-shaped plate. The torsion spring 44 is sleeved on the rotating shaft 43. One end of the torsion spring 44 is fixedly connected to the third arc-shaped plate, and the other end of the torsion spring 44 is fixedly connected to the locking block. A wire 45 for pulling the locking block to rotate is fixedly connected to the locking block. The locking block rotates around the central axis 45 of the rotating shaft 43. A pipe 46 for protecting the wire 45 is fixedly installed on the inner side of the third arc-shaped plate. The free end of the wire 45 passes through the pipe 46 and extends out of the third arc-shaped plate away from the locking block. When the telescopic sleeve assembly 2 is inserted into the patient's vagina, the tension line 45 is pulled tight, causing the locking blocks to rotate inward. When the four locking blocks 4 are closed together, they form a cone, facilitating the insertion of the telescopic sleeve assembly 2 into the patient's vagina. Once the position is determined, the tension line 45 is released, causing the locking blocks to rotate outward under the elastic deformation of the torsion spring 44, opening up and locking onto the vaginal stump, preventing the telescopic sleeve assembly 2 from slipping out of the patient's vagina due to friction during operation. In actual use, a fixing post can be set at the end of the third arc-shaped plate. When the tension line 45 is pulled tight, it is tied to the fixing post, eliminating the need for the doctor to constantly pull the tension line 45, thus freeing the doctor's hands.

[0034] Please see Figure 3 In this embodiment, an elastic protective layer 41 is fixedly connected between the locking block 4 and the third arc-shaped plate 20. When the locking block 4 opens outward, it moves the elastic protective layer 41 together, thereby isolating the torsion spring 44 and the rotating shaft 43 within the elastic protective layer 41, preventing them from directly contacting the patient and avoiding the possibility of human tissue falling into it during operation, thus affecting the normal operation of the torsion spring 44. In actual use, one end of the wire 45 can be placed inside the elastic protective layer, and the other end can pass through the elastic protective layer and extend into the pipe 46; or the wire 45 can be placed directly outside the elastic protective layer.

[0035] Please see Figure 3 In this embodiment, one end of the locking block 4 is fixedly connected to a limiting buckle 42, and a pocket 5 is detachably connected to the limiting buckle 42. After the locking block 4 is locked at the patient's vaginal stump, the doctor places the pocket 5 into the patient's body through the vagina using a tool, and then locks the end of the pocket 5 onto the limiting buckle 42. The specimen is then placed into the pocket 5 before the doctor performs the following operations. This prevents some loose pieces of tissue from falling into the patient's body and remaining inside during vaginal uterine ablation. This is mainly for malignant tumors and large uteruses, to prevent tumor dissemination during vaginal uterine ablation.

[0036] The specific usage method of this embodiment is as follows:

[0037] In use, first tighten the line 45 to make the locking blocks rotate inward. When the four locking blocks 4 come together, they form a cone, which facilitates the insertion of the telescopic sleeve assembly 2 into the patient's vagina. After the telescopic sleeve assembly 2 is inserted into the patient's vagina, place the expansion airbag 6 into the telescopic sleeve assembly 2, then open the air inlet valve 63 and manually press the airbag 61 to inflate the expansion airbag 6, gradually increasing its diameter. This pushes the third arc plate 20 outward, causing the second arc plate 21 to slide out of the third arc plate 20 and the first arc plate 22 to slide out of the second arc plate 21, thereby expanding the diameter of the telescopic sleeve assembly 2 and thus widening the patient's vagina.

[0038] After the expansion work is completed, the fixing component is placed into the shrinking sleeve component 2 to fix the shrinking sleeve component 2; then the air inlet valve 63 is closed, the air outlet valve 64 is opened, and the air bladder 61 is manually pressed to expel air from the expansion air bladder 6, so that its diameter gradually decreases, thereby removing the expansion air bladder 6.

[0039] Then, once the telescopic sleeve assembly 2 is positioned, the loosening line 45 causes the locking block to rotate outward under the elastic deformation of the torsion spring 44, opening up and locking onto the patient's vaginal stump, thus preventing the telescopic sleeve assembly 2 from slipping out of the patient's vagina due to friction during operation.

[0040] Finally, depending on the actual situation, decide whether pocket 5 is needed. If needed, after the card block 4 is secured to the patient's vaginal stump, the doctor will place pocket 5 into the patient's body through the vagina using a tool, and then attach the end of pocket 5 to the limiting buckle 42. The specimen will then be placed into pocket 5 before the doctor proceeds with the next operation. This prevents any loose pieces of tissue from falling into the patient's body and remaining inside during vaginal uterine shaving. If not needed, proceed directly to the next step.

[0041] In summary, this invention, by placing an elastic sleeve over the outside of a telescopic sleeve assembly, then expanding the telescopic sleeve assembly using an expansion component, and finally fixing the inner diameter of the telescopic sleeve assembly using a fixing component, achieves the effect of protecting the patient's vaginal wall while maximizing vaginal enlargement without obstructing the doctor's view. Therefore, this invention effectively overcomes the various shortcomings of existing technologies.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
