Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary instruments, and particularly relates to a highly efficient testicular puncture tissue scraping device. Background Art

[0002] Changes in living environment and bad living habits have led to a significant decline in sperm quality in some men, resulting in infertility. The successful clinical application of intracytoplasmic sperm injection has brought good news to many male infertility patients. For obstructive azoospermia, a syringe can be connected to a No. 5-7 scalp infusion needle, and the testicle can be percutaneously punctured for negative pressure aspiration. If there are no sperm or no active sperm in the aspirated fluid, repeat the puncture or perform contralateral testicular puncture. In the clinical IVF laboratory, the testicular puncture tissue obtained by testicular puncture needs to be scraped to release the sperm in the testicular puncture tissue, and then placed under a 200× microscope to observe the morphology and motility of the sperm, and then decide whether to freeze the sperm or use it for in vitro microfertilization. This technology has been widely used in the field of assisted reproduction and has become a routine men's examination surgery.

[0003] However, the testicular puncture tissue scraping devices currently used in laboratories are mostly syringes. During operation, after the syringe is covered with a needle, two syringes are used, one for fixing and the other for scraping the epididymal tissue. During the scraping process, the operator needs to use one hand to always fix the tissue to be scraped, and only one hand is used for operation. At the same time, the syringe can only be installed with one needle and the needle is often relatively thin, which requires the operator to spend a lot of time scraping the tissue, and the work efficiency is low. In addition, arm numbness may occur during the long scraping process, affecting the scraping efficiency, and may also lead to incomplete scraping, resulting in clinical misjudgment. If sperm cannot be observed in the punctured tissue, it is necessary to puncture again, which will undoubtedly increase the patient's psychological burden and physical pain.

[0004] At present, infertile men who are affected by factors such as working environment and mental stress need to undergo testicular puncture. It is easy to cause high labor intensity, low work efficiency, and even misdiagnosis by relying solely on existing laboratory equipment. Therefore, it is necessary to improve the existing equipment to solve and change the existing problems. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide an efficient testicular puncture tissue scraping device. The scraping device of the utility model is easy to operate, can efficiently scrape and crush testicular puncture tissue, and is beneficial to reducing the labor intensity of operators and improving work efficiency.

[0006] The technical solution of the utility model is achieved in this way:

[0009] Furthermore, the handle is composed of an upper handle and a lower handle, the lower end of the upper handle is rotatably connected to the upper end of the lower handle, and the fixing plate is arranged at the lower end of the lower handle.

[0010] Furthermore, the upper handle is rotatably set at the upper end of the lower handle through a rotating mechanism, and the rotating mechanism includes a rotating shaft and a gear fixedly set at the upper end of the lower handle. The upper end of the lower handle and the lower end of the upper handle are provided with connecting holes for the rotating shaft to pass through, so that the rotating shaft can be inserted into the connecting holes of the upper handle and the lower handle to realize the rotatable connection between the upper handle and the lower handle; and a gear clip that cooperates with the gear is provided on the upper handle, and the gear clip is retractably set in the upper handle through a spring. An operating member is provided on the upper handle, and the operating member is connected to the gear clip to realize the retraction and extension of the gear clip, thereby realizing the rotation and limiting of the upper handle.

[0011] Furthermore, the fixing plate is arranged at the lower end of the lower handle through a connecting plate, the connecting plate is horizontally fixed to the lower end of the lower handle, and the fixing plate is fixed below the connecting plate through a plurality of fixing members.

[0012] Furthermore, the thickness of the inner side wall of the holding dish gradually decreases from the bottom of the holding dish to the top of the holding dish, thereby forming a holding cavity that is smaller at the bottom and larger at the top in the holding dish.

[0013] Furthermore, the lower parts of both ends of the cutting blade are in arc structures.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1.

At the same time, the cutting blade can directly perform fixed cutting when contacting the testicular puncture tissue, which can effectively reduce labor intensity, improve work efficiency, and reduce the misdiagnosis rate.

[0016] 2. The utility model arranges the handle into an upper handle and a lower handle, and the upper handle can be rotatably arranged on the lower handle, so that the operator can adjust the angles of the upper handle and the lower handle according to the needs, so that the operator can quickly complete the scraping work of the testicular puncture tissue in the most comfortable state, which is conducive to improving work efficiency.

[0017] 3. The holding dish of the utility model has a holding cavity that is small at the bottom and large at the top.

DETAILED DESCRIPTION

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] See also Figure 1~Figure 5 , an efficient testicular puncture tissue scraping device, comprising a scraper and a holding dish 6 for holding the testicular puncture tissue.

[0026] The scraper includes a handle 1 and a cutting head 5, wherein the cutting head 5 is arranged at one end of the handle 1, and the cutting head 5 includes a horizontally arranged fixing plate 51, which is fixed to the handle 1, and a plurality of cutting blades 52 are fixedly arranged on the surface of the fixing plate 51, wherein the planes where all the cutting blades 52 are located are perpendicular to the fixing plate 51 and the cutting edges 53 of the cutting blades 52 face downward, and at the same time, all the cutting blades 52 are arranged side by side along the longitudinal direction of the handle 1, so that the cutting blades 52 on the cutting head 5 can be easily moved back and forth by holding the handle 1 and pushing and pulling, so as to scrape the testicular puncture tissue in the containing dish 6.

[0027] The handle here can be set at an angle, vertically, or horizontally. When scraping the testicular puncture tissue, the cutting blade of the scraper presses the testicular puncture tissue in the holding dish underneath, and then the push-pull handle is moved back and forth, and the cutting blade moves back and forth to scrape the testicular puncture tissue, so that the sperm in the testicular puncture tissue is released. The use of multiple rows of cutting blades here increases the contact area with the testicular puncture tissue, and the cutting blades are sharp. The testicular puncture tissue is scraped by cutting, which is conducive to reducing the time required for scraping the testicular puncture tissue. At the same time, the cutting blade can be directly fixed and cut when it contacts the testicular puncture tissue, and does not need to be fixed like a needle. It can be operated with one hand, which can effectively reduce labor intensity, improve work efficiency, and reduce misdiagnosis rate.

[0028] In specific implementation, the handle 1 is composed of an upper handle 11 and a lower handle 12, the lower end of the upper handle 11 is rotatably connected to the upper end of the lower handle 12, and the fixing plate 51 is arranged at the lower end of the lower handle 12. The upper handle 11 is rotatably arranged at the upper end of the lower handle 12 through a rotating mechanism 2, the rotating mechanism 2 includes a rotating shaft 21 and a gear 22 fixedly arranged at the upper end of the lower handle 12, the upper end of the lower handle 12 and the lower end of the upper handle 11 are provided with a connecting hole for the rotating shaft 21 to pass through, so that the rotating shaft 21 can be inserted into the connecting holes of the upper handle 11 and the lower handle 12 to realize the rotatable connection between the upper handle 11 and the lower handle 12; and a gear clip 23 cooperating with the gear 22 is arranged on the upper handle 11, the gear clip 23 is retractably arranged in the upper handle 11 through a spring 24, and an operating member 25 is arranged on the upper handle 11, the operating member 25 is connected to the gear clip 23, so as to realize the retraction of the gear clip 23, thereby realizing the rotation and limiting of the upper handle 11.

[0029] Here, the handle is arranged as an upper handle and a lower handle, and the upper handle can be rotatably arranged on the lower handle, so that the operator can adjust the angles of the upper handle and the lower handle according to the needs, so that the operator can quickly complete the scraping work of the testicular puncture tissue in the most comfortable state, which is conducive to improving work efficiency.

[0030] When in use, the operator slides the operating piece upwards, driving the gear clip to retract toward the upper end of the upper handle, so that the gear clip is disengaged from the gear. At this time, the upper handle can be rotated as needed. After adjusting to the right position, the operating piece is released, and the gear clip extends under the action of the spring, so that the gear clip is inserted between the two gear teeth of the gear, thereby achieving the limiting of the upper handle.

[0031] In a specific implementation, the fixing plate 51 is arranged at the lower end of the lower handle 12 through the connecting plate 3 , the connecting plate 3 is horizontally fixed at the lower end of the lower handle 12 , and the fixing plate 51 is fixed below the connecting plate 3 through a plurality of fixing screws 4 .

[0032] In this way, the cutting head is detachably arranged at one end of the handle, and the cutting head can be replaced as needed.

[0033] In a specific implementation, the thickness of the inner side wall 62 of the containing dish 6 gradually decreases from the bottom 64 of the containing dish to the top 63 of the containing dish, thereby forming a containing cavity 61 that is smaller at the bottom and larger at the top in the containing dish 6 .

[0034] In this way, the testicular puncture tissue can be retained in the holding cavity of the holding dish to the maximum extent, thereby reducing diffusion and lowering the difficulty of scraping the testicular puncture tissue, thereby improving the chopping efficiency.

[0035] In specific implementation, the lower parts of both ends of the cutting blade are in arc structures 54, and such a design facilitates the cutting blade to avoid the scraper from damaging the inner wall of the container during the forward and backward movement.

[0036] When using the scraping device of the utility model to scrape the testicular puncture tissue, the operator adjusts the rotating mechanism 2 through the operating member 25 according to the needs so that the handle 1 is at a suitable bending angle. Then the connecting plate 3 and the fixing plate 51 are fixed together using the fixing screw 4. Next, the testicular puncture tissue is placed in the holding cavity 61 of the holding dish 6, and then the cutting blade 52 at the front end of the scraper is used to press the testicular puncture tissue so that it contacts the bottom surface of the holding dish 6, and then the cutting blade 52 is moved back and forth to scrape the testicular puncture tissue, so that the sperm in the testicular puncture tissue is released, and the above operation is repeated until the scraping degree of the testicular puncture tissue meets the laboratory operation specification requirements.

[0037] Finally, it should be noted that the above embodiments of the present invention are only examples for illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes and modifications can be made based on the above description. It is impossible to list all implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
