[0001] This utility model relates to the field of medical device technology, specifically to a device for curettage of an animal intrauterine adhesion model. Background Technology

[0002] Intrauterine adhesions (IUA) are a condition where the uterine cavity partially or completely adheres to the endometrium after damage. Most cases are likely caused by miscarriage. IUA can lead to menstrual disorders and infertility problems. Menstrual disorders include oligomenorrhea, amenorrhea, and periodic lower abdominal pain; infertility problems include infertility, miscarriage, poor implantation after in-vitro fertilization, and placental abnormalities. The market potential for novel medical devices developed for postoperative treatment of intrauterine adhesions is enormous. To meet the need for in vivo safety and efficacy assessments of novel biomaterials or medical devices within the uterine cavity, standardized animal models of intrauterine adhesions are fundamental to experimental research.

[0003] A utility model with publication number CN111184590A discloses a device for curettage of an animal uterine adhesion model. The device includes a scraper with its front end extending into the animal's uterine cavity. The front end of the scraper is bullet-shaped, and the rear end of the scraper has a support seat positioned outside the animal's uterine cavity. Several scraping blades are formed axially on the scraper body. The bullet-shaped design of the scraper's front end facilitates uterine dilation, and the rotating scraping blades can thoroughly scrape away the animal's endometrium.

[0004] Through the above technical solution, the inventors found that the technology has at least the following problems: during use, the blade is prone to becoming dull or damaged after multiple uses and cannot be replaced, which affects its practicality. Therefore, we propose a device for curettage of an animal intrauterine adhesion model. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a device for curettage of an animal intrauterine adhesion model, comprising a shell, an inner cavity for receiving groove, a low-speed motor fixedly installed on the inner wall of the receiving groove, a drive shaft fixedly installed on the output end of the low-speed motor, the end of the drive shaft away from the low-speed motor extending through to the outside of the shell and fixedly connected to a rotating shaft, a connecting groove on one side of the rotating shaft, and a twist drill threadedly connected to the inner wall of the connecting groove inside the rotating shaft;

[0009] The twist drill includes a drill bit, a drill body, and a drill shank. The drill bit has a bullet-shaped design, the drill body has a threaded structure, and the drill shank can be threaded into the connecting groove. The inside of the rotating shaft is provided with an anti-loosening component to prevent the drill shank from loosening.

[0010] Through the above technical solution, the drill bit, drill body, and drill shank are designed with the drill shank threaded inside the rotating shaft. When the drill bit or drill body is damaged, it is easy to unscrew the drill shank for replacement.

[0019] Preferably, an elastic strip is fixedly installed on the inner wall of the elongated sliding hole inside the rotating shaft, and a rubber sealing gasket adapted to the elongated sliding hole is fixedly installed at one end of the elastic strip.

[0020] Through the above technical solution, the rubber sealing gasket can keep the elongated sliding hole in a relatively sealed environment, which can reduce the influence of the external environment on the internal structure of the elongated sliding hole. The elastic strip can limit the rubber sealing gasket and reduce the possibility of the rubber sealing gasket falling off.

[0021] Preferably, an anti-slip rubber pad is fixedly installed on the outer surface of the housing.

[0022] Through the above technical solution, the anti-slip rubber pad can increase the friction between the operator's hand and the outer casing, which can reduce the situation of the operator's hand slipping when holding the outer casing.

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0025] 1. This utility model is powered by a No. 5 battery and has a disassembly device for easy battery replacement when the battery is depleted. The low-speed motor inside converts electrical energy into rotational kinetic energy, which is then transmitted to the twist drill via a drive shaft. The rotation speed is 5-60 revolutions per minute, ensuring effective scraping of the endometrium without causing uterine damage. The drill bit has a bullet-shaped design, which facilitates the expansion of the animal's uterus and guides the entire twist drill into the uterus. The drill body has a threaded structure design, which effectively scrapes the endometrium during rotation. Its structure is not a sharp blade design, so it will not cause damage such as cutting or puncturing of uterine tissue. The drill shank can be threaded into the connecting groove, which facilitates the disassembly of the drill shank later.

[0026] 2. In this utility model, after the drill bit on the twist drill is threadedly connected to the shaft, the locking block can connect with the annular groove on the drill bit with the cooperation of the first spring, thereby limiting the drill bit and making the twist drill more stable during use, reducing the possibility of the twist drill becoming loose. When it is necessary to remove the twist drill, the operator can open the rubber sealing gasket, and then push the push plate to move. The push plate can drive the locking block to squeeze the first spring and separate it from the annular groove on the drill bit. Finally, the operator can remove the twist drill by rotating the drill bit. Attached Figure Description

[0034] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0035] This utility model provides a technical solution:

[0036] Please see Figures 1-5 A device for curettage of an animal model of intrauterine adhesions includes a housing 1. The housing 1 has an internal receiving groove. A low-speed motor 2, with a rotation speed of 5-60 rpm, is fixedly installed on the inner wall of the receiving groove. A battery sleeve 8 is housed inside the housing 1. A battery cover 9 is threaded to one side of the battery sleeve 8. A metal spring 10 is installed on the inner side of the battery cover 9. The battery sleeve 8 holds a AA battery to provide power to the low-speed motor 2. The metal spring 9 secures the AA battery inside the battery sleeve 8. The battery cover 10 can be removed by rotation for battery replacement. A toggle switch 12 for controlling the start and stop of the low-speed motor 2 is located on the outer surface of the housing 1. The toggle switch 12 is located in the upper middle part of the housing 1, allowing the operator to easily operate it with their thumb while holding the housing 1. An anti-slip rubber pad 15 is fixedly installed on the outer surface of the housing 1. The anti-slip rubber pad 15 increases the friction between the operator's hand and the housing 1, reducing the risk of slippage when holding the housing 1.

[0037] Furthermore, a drive shaft 3 is fixedly installed at the output end of the low-speed motor 2. The end of the drive shaft 3 away from the low-speed motor 2 extends through to the outside of the outer casing 1 and is fixedly connected to a rotating shaft 4. A connecting groove is provided on one side of the rotating shaft 4. A twist drill 5 is threadedly connected to the inner wall of the connecting groove inside the rotating shaft 4. The twist drill 5 includes a drill bit 51, a drill body 52, and a drill shank 53. The drill bit 51 is designed in the shape of a bullet, which is conducive to expanding the animal's uterus and facilitating the guidance of the entire twist drill 5 into the uterus. The drill body 52 is designed with a threaded structure. When rotating, the drill body 52 can effectively scrape away the endometrium. Its structure is not a sharp blade design, so it will not cause damage such as cutting or puncturing of the uterine tissue. The drill shank 53 can be threadedly connected to the inside of the connecting groove. The threaded connection makes it easy to disassemble the drill shank 53 later.

[0038] Please refer to Figure 2 , Figure 4 Figure 5 The rotating shaft 4 is internally equipped with an anti-loosening component to prevent the drill bit 53 from becoming loose. This anti-loosening component includes a first spring 6, which is fixedly installed inside the rotating shaft 4. A locking block 7 is fixedly installed at one end of the first spring 6. The drill bit 53 has an annular groove inside that matches the locking block 7. When the drill bit 53 on the twist drill 5 is threadedly connected to the rotating shaft 4, the locking block 7, in cooperation with the first spring 6, connects to the annular groove on the drill bit 53, thereby limiting the position of the drill bit 53 and making the twist drill 5 more stable during use, reducing the likelihood of it becoming loose.

[0039] Furthermore, a push plate 11 is fixedly installed on the outer side of the locking block 7, and an elongated sliding hole is opened on the outer surface of the rotating shaft 4. The push plate 11 is set inside the elongated sliding hole, and the push plate 11 can facilitate the operator to push the locking block 7 to move. An elastic strip 13 is fixedly installed on the inner wall of the elongated sliding hole opened inside the rotating shaft 4. A rubber sealing gasket 14 adapted to the elongated sliding hole is fixedly installed at one end of the elastic strip 13. The rubber sealing gasket 14 can keep the elongated sliding hole in a relatively sealed environment, which can reduce the influence of the external environment on the internal structure of the elongated sliding hole. The elastic strip 13 can limit the rubber sealing gasket 14, reducing the possibility of the rubber sealing gasket 14 falling off.

[0040] In practical use, the working principle of this utility model is as follows:

[0041] This device for curettage of an animal model of intrauterine adhesions is powered by a No. 5 battery and has a disassembly mechanism for easy battery replacement when the battery is depleted. The low-speed motor 2 inside converts electrical energy into rotational kinetic energy, which is then transmitted to the twist drill 5 via the drive shaft 3. The rotation speed is 5-60 revolutions per minute, which can effectively scrape off the endometrium without causing damage to the uterus. The outer shell 1 is made of non-slip rubber pads 15 to ensure that the operator can hold the device stably. The toggle switch 12 is designed at the top of the device, which can be easily turned on and off with the thumb after the operator holds it. The drill bit 51 has a bullet-shaped design, which is conducive to expanding the animal's uterus and facilitating the entire twist drill 5 to enter the uterine cavity. The drill body 52 has a threaded structure design. The threaded structure of the drill body 52 can effectively scrape off the endometrium when rotating. Its structure is not a sharp blade design, so it will not cause damage such as cutting or puncturing the uterine tissue. The drill shank 53 can be threaded into the connecting groove, which facilitates the disassembly of the drill shank 53 later.

[0042] When the drill bit 53 on the twist drill 5 is threadedly connected to the rotating shaft 4, the locking block 7 can connect with the annular groove on the drill bit 53 with the cooperation of the first spring 6, thereby limiting the drill bit 53 and making the twist drill 5 more stable during use, reducing the possibility of the twist drill 5 becoming loose during use. When it is necessary to remove the twist drill 5, the operator can open the rubber sealing gasket 14 and then push the push plate 11 to move. The push plate 11 can drive the locking block 7 to squeeze the first spring 6 and separate it from the annular groove on the drill bit 53. Finally, the operator can remove the twist drill 5 by rotating the drill bit 53.

[0043] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
