The dome portion 11 has a height of 3-5 cm and a lower edge diameter of 4-6 cm.
Preferably, in order to prevent the skin tissue fluid from being discharged smoothly, the elastic membrane 13 may further be uniformly provided with flow guiding holes (not shown), the flow guiding holes are circular through holes, and the flow guiding holes may be formed by punching after the elastic membrane 13 is formed.
Also provided in the centre of the top of the dome portion 11 is a central pressing member 14, this central pressing member 14 also having the shape of a dome, which has two functions: the elastic membrane 13 is fixed at the center of the dome by pressing, riveting or bonding; and the pressing component is in contact with the skin sheet when the vaginal mold is pushed, and the vaginal mold has a stable contact supporting area when penetrating into the vagina through the contact and pushing of the pressing component and the skin sheet, so that the accuracy and stability of pushing the skin sheet are ensured.
The lower side of the central pressing component 14 is fixedly connected with the supporting screw rod 19, and the two can be formed by welding or integral molding. The support screw 19 is in the form of an elongated rod provided with an external thread structure on its outer surface. The length of the support screw 19 can be set as desired. In particular, if the vaginal mold fastening band is worn on the vulvar surface in cooperation with the vaginal mold, the supporting screw 19 may be provided to be relatively long, and the supporting screw 19 may be flush with or slightly protrude from the lower edge of the lower support member 2 after the installation, so that the lower end of the supporting screw 19 serves as a coupling member with the mold fastening band. If the holding screw 19 is used only as a pushing member, it can be made relatively short (i.e. the holding screw 19 does not protrude from the lower edge of the lower support member 2) and at the lower end a simple connecting member such as a connecting snap or spline is provided to connect the extension rod for extending the length, while the extension rod can be removed when the mould is in place.
Fig. 2(c) is a sectional view along a direction a-a of the dome assembly 1 in fig. 2 (a). The internal structure of the dome assembly 1, and the working principle of its contraction and expansion, will be described in detail below with reference to fig. 2 (c).
As shown in fig. 2(c), the dome assembly 1 further comprises a screw thread 18, a first support bar 15, a second support bar 16 and a stop means 17.
The screw thread 18 is a hollow cylinder structure, the hollow inner surface of the cylinder structure is provided with an internal thread structure, the internal thread structure is matched with the external thread structure of the supporting screw rod 19, the screw thread 18 can move up and down on the supporting screw rod 19 through the rotation of the screw thread 18, and the screw thread 18 is fixed at a specific position of the supporting screw rod 19 after the rotation of the screw thread 18 is stopped.
A plurality of uniformly distributed recessed spline groove structures 181 are provided on the circumferential outer surface of the lower end of the cylindrical structure of the screw thread 18. The structure may be recessed rectangular, triangular or trapezoidal in shape. The screw thread 18 and the external rotary auxiliary member 3 can be clamped through the spline key groove structure 181, and the screw thread 18 is driven to rotate by rotating the external rotary auxiliary member 3, so that the screw thread moves up and down along the supporting screw rod 19.
As shown in fig. 3, the rotation aid 3 comprises a rod 32, a spline 31 at the top end of the rod 32, and a cavity 33 inside the rod 32. When it is desired to retract or expand the dome assembly 1, the medical staff member moves up and down along the support screw 19 by passing the support screw 19 through the cavity 33, eventually causing the spline 31 to engage and snap with the spline keyway structure 181 below the screw thread 18, and rotating the externally-connected rotation aid 3 to rotate the screw thread 18. When the screw thread 18 is moved into position, the rotation aid 3 can be pulled away.
Furthermore, a stop device 17 is provided on the support screw 19, which stop device 17 can be in the form of a fixing cam or another catch. The stopper 17 is mainly used to stop the further movement of the thread 18 towards the inside of the vagina, so as to prevent the thread 18 from moving excessively. The stop means 17 is preferably arranged in a position where the thread 18 is blocked, in which the dome portion 11 expands in diameter to the maximum.
As shown in fig. 2(c), each elastic membrane 13 is further provided with 1-2 sets of a first support rod 15 and a second support rod 16. Wherein, for each set of the first support rod 15 and the second support rod 16, the first end of the first support rod 15 is pivotally connected to the top end of the support screw rod 19; a first end of the second support bar 16 is pivotally connected with the cylindrical side surface of the screw thread 18; the second end of the first support rod 15 is pivotally connected with the second end of the second support rod 16, the second end of the first support rod 15 and the second end of the second support rod 16 are pivotally connected with each other to form an outward expanding structure supporting point 156, and the outward expanding structure supporting point 156 is further fixedly connected with the corresponding elastic membrane 13; the second end of the second support bar 16 is pivotally connected to the cylindrical side of the screw thread 18.
In particular, the pivotable structure may be a rotating shaft fixture as known in the art or other fixture methods known to those skilled in the art.
Thus, as the screw thread 18 moves up and down along the support screw 19, the sets of flared structure support points 156 are caused to contract or expand relatively, thereby further causing contraction or expansion of the diameter of the dome portion 11 formed by the plurality of elastic membranes 13 secured to the sets of flared structure support points 156. When the screw thread 18 stops moving and is fixed to a specific position (e.g., a position defined by the stopper 17) of the supporting screw rod 19, each set of the first supporting rod 15, the second supporting rod 16 and the supporting screw rod 19 constitutes a triangular frame structure, and the triangular frame structure is in a very stable supporting state when the top of the supporting screw rod 19 and the vertex where the screw thread 18 is located are fixed, thereby providing stable and strong support for the dome portion 11 constituted by the elastic diaphragm 13.
Referring to fig. 4, the retracted or expanded configuration of the dome assembly 1 is described in detail below. First, when the vaginal mold is pushed into the vagina, the dome member 1 of the vaginal mold is in a contracted state, and after the vaginal mold is pushed to an appropriate position, the dome member 1 needs to be expanded. The practitioner engages the rotation aid 3 under the thread 18 of the dome member 1 and rotates the thread 18 in the corresponding direction, thereby causing the thread 18 to move towards the top of the mould (i.e. deep in the vagina). As the screw thread 18 moves upward, the sets of support points 156 of the flaring structure gradually expand outward, thereby bringing the dome portion 11, which is composed of a plurality of elastic membranes 13, open until the dome portion 11 expands to a maximum diameter state when the screw thread 18 abuts against the position limiting member 17, and the expansion is finished. The principle when the vaginal mold needs to be extracted is the same as the principle, only the rotation direction is opposite, and the description is omitted.
As shown in fig. 5, the vaginal mold provided in embodiment 1 of the present invention further includes a lower support member 2. The lower support member 2 has a hollow cylindrical shape. The hollow column has an outer diameter of 5-7cm and a height of 5-9 cm.
The upper edge of the lower supporting component 2 is provided with a clamping groove 21; the shape and size of the engaging groove 21 are matched with those of the lower edge of the dome portion, so that stable engagement and fixation can be achieved. Specifically, the slot is the same shape as the dome portion and is of uniform size or has a tolerance of + -0.5 mm + -3 mm to achieve a tight fit of the snap fit.
A plurality of flow guide grooves 23 are formed on the side wall of the cylinder of the lower support assembly 2, and a plurality of through holes 22 are uniformly distributed on the surface of the cylinder between the flow guide grooves 23. The flow guide groove 23 and the through hole 22 can facilitate the tissue fluid to flow out, realize the ventilation effect and inhibit the reproduction of anaerobic bacteria in the vagina.
In actual use, during the insertion of the mould, the dome assembly 1 is first pushed into the contracted state, and then the lower support assembly 2 is pushed in after the dome portion 11 is expanded to the maximum according to the process shown in fig. 4, and the lower edge of the dome portion 11 is engaged with the engaging groove 21 of the upper edge of the lower support assembly 2, thereby completing the insertion and assembly of the mould. In extracting the mould, the screw thread 18 is first rotated using the rotation aid 3 in the opposite direction to that of figure 4, so that the dome portion 11 is diametrically relatively contracted, the vagina assuming a slightly relaxed condition due to the contraction of the top dome portion 11, at which time the lower support member 2 is extracted, and then the screw thread 18 is further rotated in the opposite direction to that of figure 4, so that the dome portion 11 is fully retracted, and finally the dome member 1 is extracted.
Because the diameter of the dome assembly 1 positioned at the top of the mould can be manually controlled to shrink or expand, the diameter of the dome assembly can be relatively shrunk when the mould is pushed towards the interior of a vagina, and the diameter of the dome assembly is expanded after the mould is moved to a proper position, so that the damage to the top of a leather sheet when the mould is pushed can be avoided; when the mould is taken out, the diameter of the dome assembly 1 can be firstly contracted, the mould is taken out after the skin sheet is separated from the dome assembly 1, so that the skin sheet can be prevented from being peeled off again when the mould is taken out, and the success rate of the operation is improved.
Example 2
As an alternative example to example 1, example 2 provides a vaginal mold that can control the supporting pressure by replacing the second support rod 16 with a piezoelectric material under substantially the same conditions as the vaginal mold structure provided in example 1.
As shown in fig. 6, the construction of the vaginal mold in example 2 is substantially the same as that of example 1, except that the plurality of sets of second supports 16 are replaced with second supports 16' at least partially comprising sections of piezoelectric material, preferably disposed near the central axis of the dome portion 11. A voltage measuring device 161 ' is also provided on the piezoelectric section of the second support 16 ' to collect voltage variations due to pressure, and the voltage measuring device 161 ' is connected to an external processing device 163 ' by wire or wirelessly to calculate and analyze the pressure to which the second support 16 ' is subjected in the support.
When the dome portion 11 is expanded by rotating the auxiliary element 3 after the vaginal reconstruction operation, the pressure received by the second support element 16 ' is gradually increased as the support point 156 of the flaring structure is gradually flared, the voltage generated by the piezoelectric section thereof is also gradually increased, and the processing means 163 ' can calculate the pressure value to which the second support element 16 ' is subjected in the support. And the processing means 163 'prestores threshold values of the pressure to which the second support 16' is subjected. When the pressure experienced by the second support 16 ' reaches a threshold value, the processing device 163 ' prompts the healthcare worker for a pressure warning of the second support 16 '. The medical practitioner ceases the dilating action of rotating the rotary assist member 3 and the threads 18 are fixed at or below the pressure threshold.
At this time, the diameter of the lower edge of the dome portion 11 is measured by an endoscope. To fit the dome assembly 1 of example 2, the vaginal mold of example 2 was provided with multiple sets of lower support members 2 of different diameter sizes. Preferably, groups of lower support members 2 of 4-6cm diameter are prepared according to the physiological structure of a person, and preferably, one lower support member 2 is prepared every 5mm interval in a section of 4-6cm diameter. After the endoscope measures the diameter of the lower edge of the corresponding dome portion 11, the corresponding lower ground support assembly 2 is selected. The diameter of the lower edge of the domed portion 11 is the same as the groove size of the upper edge of the lower support assembly 2 or has a tolerance of + -1 mm + -3 mm to achieve a tight fit for the snap fit.
Through embodiment 2, the vagina mold capable of controlling the supporting pressure can avoid the problems that when the mold is extruded into the vagina to enable the mold to be in close contact with the top end of the vagina, the skin sheet at the top end of the vagina is subjected to the largest stress action, the skin sheet at the top of the vagina is easy to be too thin, cracks and inflammation are generated, and the postoperative recovery quality of a patient is improved.
