Problems solved by technology

This type of vaginal mold has the following problems: 1) when the mold is squeezed into the vagina so that the mold is in close contact with the top of the vagina, the skin at the top of the vagina receives the greatest stress, which easily causes the skin at the top of the vagina to be too thin, resulting in r...

Embodiment 1

[0039] Such as figure 1 As shown, the vaginal mold provided in Embodiment 1 of the present invention includes a dome component 1 and a lower support component 2 . The dome assembly 1 is in the shape of a dome whose diameter can shrink or expand. The lower edge 12 of the dome portion 11 of the dome assembly 1 is inserted into the slot 21 on the upper edge of the lower support assembly 2 . The shape and size of the locking groove 21 coincide with the shape and size of the lower edge of the dome portion, so that stable locking and fixing can be realized. Specifically, the clip groove and the dome part have the same shape and the same size or have a tolerance of ±0.5mm-±1mm, so as to achieve a tight fit for snap-fitting.

[0040]Fig. 2(a) is a front view of the structure of the dome assembly 1, and Fig. 2(b) is a top view of the structure of the dome assembly 1 viewed from one side of the dome. As shown in FIG. 2( a ), the dome assembly 1 in Embodiment 1 of the present invention...

Embodiment 2

[0061] As an alternative embodiment of embodiment 1, embodiment 2 provides a controlled A vaginal mold that supports pressure.

[0062] Such as Figure 6 As shown, the structure of the vaginal mold in embodiment 2 is roughly the same as that in embodiment 1, only the sets of second support members 16 are replaced by second support members 16' at least partially comprising piezoelectric material segments, the The piezoelectric section is preferably arranged near a position close to the central axis of the dome portion 11 . A voltage measurement device 161' is also provided on the piezoelectric section of the second support 16' to collect voltage changes due to pressure. The voltage measurement device 161' is connected to an external processing device in a wired or wireless manner 163', so that the calculation and analysis can obtain the pressure on the second support member 16' during the support.

[0063] When the dome part 11 is expanded by rotating the auxiliary part 3 af...

Embodiment 3

[0067] The manufacturing method of the vagina mold among the embodiment 1 will be illustrated in the embodiment 3, specifically as follows:

[0068] The first step is to make the central pressing component 14: two circular sheets of the same size are passed through the stamping process of the titanium alloy thin plate, and then the sheets are hydroformed to form two dome-shaped sheets with the same arc shape .

[0069] Second step, make elastic membrane 13, it comprises:

[0070] Firstly, the titanium alloy skeleton of the elastic diaphragm 13 is made, and the β titanium alloy rod-shaped material is hydroformed to form a curved rod-shaped material.

[0071] Subsequently, two pieces of 1 / n (n=4-8) dome-shaped porous rubber are respectively placed on the upper and lower surfaces of 1-2 radian rod-shaped materials to form a sandwich structure, and the above-mentioned The elastic diaphragm 13 of sandwich structure is fixed.

[0072] The third step is to fix the elastic diaphrag...

Abstract

The invention relates to a vaginal mold for vaginal reconstruction comprising a collapsible and expandable dome assembly (1) and a lower support assembly (2) snapped to the dome assembly (1). The vaginal mold prevents the vaginal mold from contacting the vaginal tip when the mold is squeezed into the vagina so that the mold is in close contact with the vaginal tip, The vaginal top skin graft receives the biggest stress function, causes the vaginal top skin graft to be too thin, produces the rupture, the inflammation and so on question as well as the vaginal top skin graft closely joins with the vaginal mold top surface, produces the skin graft and the mold top adhesion, causes the skin graft the peeling off question again when takes out the mold.

Description

technical field [0001] The invention relates to an auxiliary device for postoperative rehabilitation, in particular to a vaginal mold for vaginal reconstruction and a manufacturing method thereof. Background technique [0002] Vaginal reconstruction is mainly used for patients with congenital absence of vagina, androgen insensitivity syndrome, true hermaphroditism and certain pelvic malignancies with postoperative vaginal defects, the most common being congenital absence of vagina, ie MRKH syndrome. The purpose of vaginal reconstruction surgery is to reconstruct the vagina, solve the patient's sexual life problems, and improve the patient's quality of life. [0003] Vaginal reconstruction surgery usually needs to create an artificial vaginal cavity between the urethra and rectum. There are various types of vaginal reconstruction surgery. Among them, vaginal molds need to be placed in a short period of time after sigmoid colon replacement, and vaginal molds need to be placed ...
