Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an intraoperative sterile sperm storage device. Background Technology

[0002] Due to the interaction of genetic factors, environmental degradation, unhealthy lifestyles and reproductive tract infections, the incidence of infertility is rising year by year. Infertility caused by azoospermia has reached 1% of the male population, with non-obstructive azoospermia accounting for the vast majority.

[0003] Currently, microsurgical sperm retrieval is an important treatment for non-obstructive azoospermia. Taking Tongji Hospital in Wuhan as an example, approximately 300 microsurgical sperm retrieval procedures are performed annually. With the popularization of microsurgical techniques and the continued rise in the incidence of non-obstructive azoospermia, more and more reproductive centers or urology departments will perform this type of surgery, making the establishment of standardized operating procedures for this procedure inevitable. During the surgery, the surgeon needs to transfer the seminiferous tubules, which may contain spermatogenic foci, obtained under a microscope to the scrub nurse on the operating table for temporary storage, and then hand them over to the laboratory personnel off-stage for further processing. Because the surgery often involves taking tissue from different parts of the testis, a single surgery may yield 5-6 or more testicular tissue samples. With such a large number of tissue samples, the scrub nurse is prone to mixing up and losing the tissues on the operating table, and the laboratory personnel off-stage are prone to errors in labeling, transporting, and processing, resulting in confusion and contamination of testicular tissue from different parts of the patient's body. On the other hand, during current surgeries, these removed tissues are usually placed on gauze or homemade placement paper, which greatly increases the incidence of sperm loss and contamination.

[0004] Therefore, how to provide an intraoperative sperm storage dish for microsurgical sperm retrieval surgery, so that medical staff can store the tissue retrieved during the operation more quickly and efficiently, is a technical problem that urgently needs to be solved by those skilled in the art.

[0041] Please see Figure 1-3 This embodiment provides an intraoperative sterile sperm storage device, which includes: a storage dish 1, the top surface of which is recessed downward to form a sunken platform 11, and a plurality of downwardly opening placement units 12 provided on the sunken platform 11, each of which is cylindrical; and a plurality of storage nets 2, the number of which is the same as the number of placement units 12; wherein each of the plurality of storage nets 2 includes a filter 21 and a support ring 22, the support ring 22 being sleeved on the top of the filter 21, the opening of the filter 21 being connected to the inner side of the support ring 22, and the outer diameter of the support ring 22 being larger than the diameter of the placement unit 12, so that when the plurality of filter nets 21 are placed inside the plurality of placement units 12, the bottom surface of the support ring 22 abuts against the sunken platform 11.

[0042] Specifically, this utility model provides an intraoperative sterile sperm storage device, including a storage dish 1 and several storage nets 2. During surgery, the surgeon can remove sperm tissue and hand it over to the scrub nurse for temporary storage in the storage dish 1 to ensure tissue safety. The top surface of the storage dish 1 is recessed downwards to form a sinking platform 11, on which several downward-opening placement units 12 are provided. The sinking platform 11 prevents saline or tissue placed in the units from leaking to the outside of the storage dish 1, and also provides... The disc 3 provides a platform for placement; the number of placement units 12 is adapted to the number of storage nets 2, and each placement unit 12 contains a corresponding storage net 2. The placement unit 12 is used to hold low-temperature physiological saline. When the storage net 2 is located inside the placement unit 12, the physiological saline can pass through the filter 21 to contact the sperm and improve their activity. At the same time, adding physiological saline to the placement unit 12 can also prevent tissue from sticking to the wall and drying out. Each storage net 2 includes a filter 21 and a support ring 22. The diameter of the opening of the filter 21 is the same as the diameter of the support ring 22. The filter 21 is fitted to connect with the inner surface of the support ring 22, with the outer diameter of the support ring 22 being larger than the diameter of the placement unit 12. When the filter 21 is placed inside the placement unit 12, the bottom surface of the support ring 22 abuts against the sinking platform 11, thus supporting the filter 21 and keeping it stable. This prevents the filter 21 from deforming during handling, which could lead to tissue leakage. The operator can also directly remove the entire filter 21 by gripping the support ring 22. Furthermore, because sperm and saline have different densities... During the soaking process, the sperm and the extracted tissue will not be separated into the placement unit 12 by the filter 21. The filter 21 is only used to permeate physiological saline to improve sperm motility and prevent tissue drying. As an feasible method, the storage dish 1 is to be made of a high-temperature resistant sterilization material and can be repeatedly sterilized. In this way, a sperm storage dish for intraoperative use in microsurgical sperm retrieval surgery is constructed. Through the storage dish 1 and the separately set storage net 2, medical staff can quickly, orderly and efficiently store sperm and other tissues, avoiding tissue omission and loss.

[0043] In some possible implementations, the storage net 2 further includes an extension net 23, the bottom of which is connected to the support ring 22, and a pull rope 24 is provided on the top edge of the extension net 23; the diameter of the top of the extension net 23 is larger than the diameter of the bottom of the extension net 23, so that the top of the extension net 23 is turned outward and placed outside the support ring 22.

[0044] Specifically, such as Figure 3 As shown, the storage net 2 also includes an extension net 23, which is equipped with a pull rope 24. When the tissue collection is completed and needs to be transferred, medical staff can use the pull rope 24 to tie the end of the extension net 23 to prevent the tissue from flowing out or being contaminated.

[0045] In some possible implementations, the intraoperative sterile sperm storage device also includes a disc 3 with a plurality of circular holes 31 through it. The disc 3 is placed inside a sunken platform 11, with the bottom surface of the disc 3 abutting against the surface of the sunken platform 11. The diameter of the disc 3 is the same as the diameter of the sunken platform 11. The diameter of the plurality of circular holes 31 is the same as the diameter of the plurality of placement units 12, and the opening positions of the plurality of circular holes 31 are the same as the opening positions of the plurality of placement units 12.

[0046] Specifically, such as Figure 4 As shown, with the arrangement of the disc 3, medical staff can place the storage net 2 through the disc 3 into the storage dish 1. The support ring 22 in the storage net 2 abuts against the disc 3. Thus, when it is necessary to change the saline solution, medical staff do not need to lift and separate several storage nets 2 one by one. They can directly lift all the storage nets 2 together through the disc 3, which is convenient for quickly separating several storage nets 2 from the storage dish 1 and for changing the saline solution. The disc 3 has a second handle 32 in the center, which makes it easy for medical staff to lift the disc 3. As an feasible method, the disc 3 should be made of transparent material to avoid obscuring the markings.

[0047] In some possible implementations, the sunken platform 11 is also engraved with several marking characters; the marking characters are arranged around the several placement units 12.

[0048] Specifically, the sinking platform 11 is also engraved with several marking characters. Taking the embodiment in the figure as an example, there are four placement units 12. The marking characters can be numbers 1-4, and they are engraved below the four placement units 12 in the sinking platform 11. When medical staff can collect multiple sperm tissues at one time, they can put the relevant extracted tissues in order according to the engraved numbers from smallest to largest. This makes it easier for the scrub nurse to pass the relevant tissues to the experimental staff below the table in order, making the postoperative specimen processing work more convenient.

[0049] In some possible implementations, the support ring 22 is also provided with a first lifting handle 25.

[0050] Specifically, the first handle 25 facilitates the quick lifting of the storage net.

[0051] In some possible implementations, the intraoperative sterile sperm storage device also includes a protective cover 4, the size of which is adapted to the size of the storage dish 1, and the protective cover 4 is removably attached to the top of the storage dish 1.

[0052] Specifically, the protective cover 4 protects sperm tissue from external contamination during the transfer of the intraoperative sterile sperm storage device.

[0053] In some possible implementations, the sunken platform 11 is circular, and several placement units 12 are evenly arranged around the center of the storage dish 1.

[0054] Specifically, as shown in the figure, several placement units 12 are evenly arranged around the center of the storage dish 1, making it easy for medical staff to view.

[0055] Finally, it should be noted that the above embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto.
