Description

Technical Field

[0001] The utility model relates to the technical field of medical cosmetic devices, in particular to a device for shearing and filling acellular dermal matrix of a female vagina or vulva. Background Art

[0002] Acellular dermal matrix (ADM) is prepared by removing the epidermis and cellular components in the dermis of full-thickness skin of the same or different species, and only retaining the dermal extracellular matrix (ECM) with a complete fiber lattice structure. This material has a porous three-dimensional network structure and has the ability to quickly aggregate cells and make them adhere, migrate and differentiate, thereby promoting collagen synthesis and new blood vessel formation. ADM materials have been increasingly widely used because of their good affinity, biocompatibility, certain mechanical properties, and the ability to induce cell growth and proliferation. Its application areas include burns, plastic surgery, surgery, and wound repair. At present, commercial ADM is also on the market in large quantities.

[0003] Filling ADM in the private parts of aging women (such as the vaginal wall, labia majora, etc.) through minimally invasive implantation medical means can promote the repair and reconstruction of soft tissues and improve the morphology of these parts. At present, most ADM products are in strip or sheet form, and need to be manually cut before filling, such as soaking the ADM product in saline, cutting it with stainless steel scissors, and preparing it into micronized ADM, for example, cutting it into micronized ADM with a circumscribed circle less than 3mm, and then performing subsequent filling. However, manual shearing has the disadvantages of difficulty in ensuring the consistency of the particle size of the material, time-consuming and labor-intensive, and easy to be contaminated by bacteria.

[0029] The following describes a device for shearing and filling acellular dermal matrix in a female vagina or vulva according to an embodiment of the present invention with reference to the accompanying drawings.

[0030] Embodiment 1

[0031] See also Figure 1 to Figure 2, the present embodiment is a device for shearing and filling the acellular dermal matrix of the female vagina or vulva, which includes a shearing barrel and a sorting barrel 1. The shearing barrel includes an upper cover 2, a shearing device, and a barrel wall 3. The upper cover 2 is sealedly connected to one end of the barrel wall 3, and the sorting barrel 1 is sealedly connected to the other end of the barrel wall 3. The upper cover 2, the barrel wall 3, and the sorting barrel 1 together form a closed space. In the present embodiment, the upper cover 2 is threadedly connected to one end of the barrel wall 3, that is, the upper cover 2 and the barrel wall 3 are correspondingly formed with threads, and the sorting barrel 1 is threadedly connected to the other end of the barrel wall 3, that is, the barrel wall 3 of the sorting barrel 1 is correspondingly formed with threads. Of course, the upper cover 2 and one end of the barrel wall 3, and the sorting barrel 1 and the other end of the barrel wall 3 can also be sealed in other ways, such as a snap-on connection with a sealing ring, which are not listed here one by one.

[0032] The shearing device includes a rotating shaft 4, at least two rotating blades 5, a driving mechanism 6, a control circuit 7, and a temperature sensor. The rotating blades 5 are arranged in a first space surrounded by the upper cover 2 and the barrel wall 3, and the driving mechanism 6 is arranged in the upper cover 2. The rotating blades 5 installed on the peripheral wall of the rotating shaft 4 are driven to rotate by driving the rotating shaft 4 to rotate. During the rotation of the rotating blades 5, the decellularized dermal matrix in the mixture of the decellularized dermal matrix and physiological saline placed in the first space can be sheared. The driving mechanism 6 can be composed of a motor 8, a first gear 9 installed at the output end of the motor 8, and a second gear 10 sleeved on the rotating shaft 4, and the first gear 9 is meshed with the second gear.

[0033] The temperature sensor is used to detect the temperature of the mixture of the decellularized dermal matrix and the physiological saline placed in the first space, and send it to the control circuit 7 electrically connected to the driving mechanism 6. Since high-speed shearing of the decellularized dermal matrix will generate heat, high temperature will denature the decellularized dermal matrix. Therefore, when the temperature of the mixture is greater than or equal to the preset temperature, which can be set to 40°C, the control circuit 7 controls the driving mechanism 6 to temporarily stop working, and the driving mechanism 6 continues to work after a preset time.

[0034] The temperature sensor is electrically connected to the control circuit 7 , and the temperature sensing element 11 of the temperature sensor can be fixed to the upper cover 2 and is located in the first space.

[0035] The sorting barrel 1 is provided with a filter 12, which is arranged at the connection between the barrel wall 3 and the sorting barrel 1, and is used to filter out the sheared acellular dermal matrix with a mesh size less than or equal to the mesh size of the filter 12. The mesh size of the filter 12 can be 3 mm.

[0036] The device for shearing and filling the acellular dermal matrix of the female vagina or vulva can be used as follows:

[0037] 1. Remove the upper cover 2 and place the acellular dermal matrix and saline into the device through the opening of the barrel wall 3;

[0038] 2. Install the upper cover 2, turn the device upside down, and start the device;

[0039] 3. After the acellular dermal matrix is ​​sheared, place the device upright. Figure 1 In the state shown, the sheared acellular dermal matrix and saline solution with a mesh size smaller than or equal to the mesh size of the filter 12 will fall into the sorting barrel 1 through the filter 12;

[0040] 4. Remove the sorting barrel 1, take out the filter 12, and pour out the acellular dermal matrix and physiological saline in the sorting barrel 1.

[0041] The device for shearing and filling the acellular dermal matrix for the female vagina or vulva is used to shear the acellular dermal matrix, so that the acellular dermal matrix can be sheared to a required size without the need for manual shearing, thus saving time and effort and reducing the probability of the acellular dermal matrix contacting with external bacteria.

[0042] In this embodiment, the shear barrel further includes a power supply 13 arranged in the upper cover 2, and the power supply 13 is electrically connected to the driving mechanism 6 and the control circuit 7. The power supply 13 can be a rechargeable power supply such as a lithium battery, a lithium polymer battery, etc., and the upper cover 2 can also be provided with a charging interface for connecting to an external power supply to provide power to the power supply 13.

[0043] Embodiment 2

[0044] See also Figure 3 to Figure 4 , the present embodiment is a device for shearing and filling the acellular dermal matrix of the female vagina or vulva, which includes a shearing barrel and a collecting barrel 21. The shearing barrel includes an upper cover 22, a shearing device, a barrel body 23, and a screener, and the upper cover 22 is installed at the opening of the barrel body 23. The shearing device includes a rotating shaft 24, at least two rotating blades 25, and a driving mechanism 26. The driving mechanism 26 is arranged in the upper cover 22, and drives the rotating blades 25 installed on the peripheral wall of the rotating shaft 24 to rotate by driving the rotating shaft 24 to rotate. The rotating shaft 24 is located on the virtual center line of the barrel body 23. During the rotation of the rotating blades 25, the acellular dermal matrix in the mixture of the acellular dermal matrix and physiological saline placed in the barrel body 23 can be sheared. The driving mechanism 26 can be composed of a motor 27, a first gear 28 installed at the output end of the motor 27, and a second gear 29 sleeved on the rotating shaft 24, and the first gear 28 is meshed with the second gear 29.

[0045] The screener includes a cylindrical screen cylinder 30, the lower edge of which is fixed to the bottom plate of the barrel 23, and the virtual center line of the screen cylinder 30 coincides with the virtual center line of the barrel 23. The screener also includes N partitions 31, N is greater than or equal to 2, and each of the partitions 31 is distributed in a circular array with the virtual center line of the barrel 23 as the center, dividing the space between the barrel 23 and the screen cylinder 30 into N retention areas. During the shearing process, the acellular dermal matrix equal to or smaller than the set size can be retained in the retention area.

[0046] Specifically, the portion of the sieve cylinder 30 located between two adjacent partitions 31 includes a sieve hole area 32 and a drainage area 33 distributed along the rotation direction of the rotating blade 25, and the sieve hole size of the sieve hole area 32 is larger than the size of the drainage hole of the drainage area 33. The mixture of the acellular dermal matrix and the physiological saline sheared to a size equal to or smaller than the set size can enter the retention area from the sieve holes of the sieve hole area 32 under the action of the rotating blade 25, and then at least part of the physiological saline in the mixture is discharged from the drainage hole of the drainage area 33, thereby reducing the amount of acellular dermal matrix sheared to a size that is too small.

[0047] In one embodiment, the sieve hole area 32 and the drainage area 33 are arranged adjacent to each other. The heights of the sieve hole area 32 and the drainage area 33 are the same as the height of the sieve drum 30.

[0048] In another embodiment, the portion of the sieve cylinder 30 located between two adjacent partitions 31 may further include a first non-porous area 34 located between the sieve hole area 32 and the drainage area 33, and the first non-porous area 34 is not provided with sieve holes, drainage holes, etc. The heights of the sieve hole area 32, the drainage area 33, and the first non-porous area 34 are all the same as the height of the sieve cylinder 30. In this embodiment, the physiological saline discharged from the drainage hole can disturb the mixture located inside the sieve cylinder 30, thereby improving the shearing efficiency.

[0049] In another embodiment, the portion of the sieve cylinder 30 between two adjacent partitions 31 may further include a second imperforate area 35 between the drainage area 33 and the partition 31. Similarly, the second imperforate area 35 is not provided with sieve holes, drainage holes, etc. The heights of the sieve hole area 32, the drainage area 33, the first imperforate area 34, and the second imperforate area 35 are all the same as the height of the sieve cylinder 30. In this embodiment, the influence of the physiological saline discharged from the drainage hole on the mixture about to enter the sieve hole is reduced.

[0050] The bottom plate of the barrel body 23 is provided with a plurality of discharge ports 36 directly communicating with the corresponding sieve hole areas 32. The collecting barrel 21 includes a top cover 37, and the top cover 37 is provided with a plurality of feed ports 38 that can overlap with the discharge ports 36 of the barrel body 23. The number of the feed ports 38 can be the same as the number of the discharge ports 36. The lower end of the barrel body 23 is docked with the upper end of the collecting barrel 21, and the relative positions of the discharge ports 36 and the feed ports 38 can be changed by rotating the barrel body 23. When the feed ports 38 of the top cover 37 and the discharge ports 36 of the barrel body 23 are in a staggered state, the internal space of the collecting barrel 21 and the retention area are isolated. When the feed ports 38 of the top cover 37 and the discharge ports 36 of the barrel body 23 are in a superimposed state, the internal space of the collecting barrel 21 and the retention area are connected.

[0051] The device for shearing and filling the acellular dermal matrix of the female vagina or vulva can be used as follows:

[0052] 1. Rotate the barrel body 23 so that the feed port 38 of the top cover 37 and the discharge port 36 of the barrel body 23 are in a staggered state;

[0053] 2. Remove the upper cover 22 and place the acellular dermal matrix and saline into the device through the opening of the barrel 23;

[0054] 3. Install the upper cover 22 and start the device;

[0055] 4. After the acellular dermal matrix is ​​sheared, the barrel body 23 is rotated so that the feed port 38 of the top cover 37 and the discharge port 36 of the barrel body 23 are in an overlapping state; the acellular dermal matrix in the retention area falls into the collection barrel 21 through the discharge port 36. Of course, during this process, the physiological saline also falls into the collection barrel 21 through the discharge port 36.

[0056] 5. Separate the barrel body 23 from the collection barrel 21, take out the top cover 37, and pour out the acellular dermal matrix and physiological saline in the collection barrel 21.

[0057] In this embodiment, the device for shearing and filling the acellular dermal matrix of the female vagina or vulva may also include a control circuit 39 and a temperature sensor, wherein the temperature sensor is used to detect the temperature of the mixture of the acellular dermal matrix and the physiological saline placed in the barrel 23, and send it to the control circuit 39 electrically connected to the drive mechanism 26. Since high-speed shearing of the acellular dermal matrix will generate heat, high temperature will denature the acellular dermal matrix. Therefore, when the temperature of the mixture is greater than or equal to the preset temperature, which can be set to 40°C, the control circuit 39 controls the drive mechanism 26 to temporarily stop working, and the drive mechanism 26 continues to work after the preset time.

[0058] The temperature sensor is electrically connected to the control circuit 39 , and the temperature sensing element 40 of the temperature sensor can be fixed below the upper cover 22 via a bracket 41 .

[0059] The device for shearing and filling the acellular dermal matrix for the female vagina or vulva is used to shear the acellular dermal matrix, and the acellular dermal matrix can be sheared to a required size without the need for manual shearing, which saves time and effort, and reduces the probability of the acellular dermal matrix contacting with external bacteria. The setting of the filter effectively reduces the number of acellular dermal matrices sheared into too small a size, and the obtained acellular dermal matrix is ​​uniform in size.
