[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-3 As shown, this utility model provides a technical solution: a detachable uterine curette, including a handle 1. The handle 1 serves as the operating grip of the entire instrument, and its design fully considers the usage habits and comfort of medical staff. It adopts an ergonomic shape to facilitate gripping and applying force. A sliding disassembly device 2 is provided on the left side of the outer surface of the handle 1. This device is the core component for enabling quick and convenient disassembly of the curette. Simultaneously, a movable circular block 3 is inserted inside the handle 1, and a curette plate 4 is fixedly installed on the left side of the movable circular block 3. The curette 4 is a working component that directly contacts and scrapes the endometrium or uterine cavity tissue. Its shape and size are carefully designed to meet the needs of different surgical scenarios. A spring plate 5 is fixedly installed in the middle of the inner side of the curette 4. The spring plate 5 plays a certain role in buffering and elastic adjustment, so that the curette can better fit the inner wall of the uterine cavity when scraping tissue, avoiding excessive damage to the uterus. A positioning cylinder 6 is fixedly installed in the middle of the outer side of the curette 4. The positioning cylinder 6 cooperates with the positioning structure on the handle 1 to ensure the accuracy and stability of the curette 4 installation.

[0022] The sliding disassembly device 2 includes a sliding sleeve 201 slidably mounted on the outer surface of the grip handle 1. An arc-shaped rubber strip 202 is fixedly mounted on the outer surface of the sliding sleeve 201. The design of the arc-shaped rubber strip 202 increases the friction between the medical staff's hand and the sliding sleeve 201 during operation, making the operation of pushing the sliding sleeve 201 more stable and reliable, and preventing slippage. A fixing plate 203 is also fixedly mounted on the outer surface of the sliding sleeve 201. A compression spring 204 is fixedly mounted on the left side of the fixing plate 203. A connecting vertical plate 205, which connects to the outer surface of the grip handle 1, is fixedly mounted on the left end of the compression spring 204. The compression spring 204 is in a compressed state under normal conditions, providing a rightward elastic force to the sliding sleeve 201 to keep it in its initial position. When the scraper needs to be removed, the medical staff pushes the sliding sleeve 201 to the left to overcome the elastic force of the compression spring 204, thereby separating the scraper plate 4 from the handle 1. In addition, a stabilizing crossbar 206 is fixedly installed on the left side of the fixing plate 203, which passes through the connecting vertical plate 205. The function of the stabilizing crossbar 206 is to limit the movement trajectory of the sliding sleeve 201, so that it can only slide along the axial direction of the handle 1, avoiding shaking or deviation, and ensuring the stability and reliability of the disassembly operation.

[0023] Specifically, such as Figure 1 and Figure 2As shown, a positioning hole is provided on the left side of the outer surface of the grip handle 1, and a positioning cylinder 6 passes through the positioning hole. The tight fit between the positioning cylinder 6 and the positioning hole ensures the accuracy of the curette plate 4 during installation, so that the curette will not shake or shift during the surgical operation, thus improving the precision of the surgical operation. A circular cavity is provided inside the grip handle 1. The size of the circular cavity is adapted to the size of the moving block 3. The moving block 3 can move freely in the circular cavity. When the curette plate 4 is installed in place, the fit between the moving block 3 and the circular cavity can further enhance the stability of the curette plate 4, making it more secure and reliable during operation.

[0024] Specifically, such as Figure 3 As shown, the inner wall of the sliding sleeve 201 is provided with a sliding protrusion, and the left side of the outer surface of the grip handle 1 is provided with a long strip groove. The sliding protrusion slides in the long strip groove. This sliding fit structure further enhances the stability and smoothness of the sliding of the sliding sleeve 201, and also limits the range of motion of the sliding sleeve 201 to prevent it from falling off the grip handle 1. The interior of the connecting vertical plate 205 is provided with a sliding circular hole, and the stabilizing crossbar 206 slides inside the sliding circular hole. This structure allows the stabilizing crossbar 206 to slide smoothly in the connecting vertical plate 205, further ensuring the stability and reliability of the sliding of the sliding sleeve 201.

[0025] The working principle of this utility model is as follows:

[0026] S1. When installing the scraper, first align the movable round block 3 with the circular cavity inside the handle 1 and slowly insert it. Since the size of the circular cavity is compatible with the movable round block 3, the movable round block 3 can smoothly enter the circular cavity and move freely in it. Next, align the positioning cylinder 6 on the scraper plate 4 with the positioning hole on the left side of the outer surface of the handle 1 and gently push the scraper plate 4 so that the positioning cylinder 6 is inserted into the positioning hole. At this time, the scraper plate 4 is installed in place. The movable round block 3 plays a role in stabilizing the scraper plate 4 in the circular cavity, while the cooperation between the positioning cylinder 6 and the positioning hole ensures the accuracy of the installation of the scraper plate 4 and prevents it from shaking or shifting.

[0027] S2. When medical staff use the uterine curette for surgical procedures, they hold the handle 1 and slowly insert the curette 4 into the patient's uterine cavity. During the scraping of the endometrium or uterine tissue, the spring plate 5 on the inner side of the curette 4 can be elastically adjusted to a certain extent according to the shape of the uterine cavity wall, so that the curette 4 fits the uterine cavity wall better and avoids excessive damage to the uterus. At the same time, because the accuracy and stability of the curette 4 installation are guaranteed, medical staff can control the curette operation more precisely, improving the safety and efficiency of the surgical procedure.

[0028] S3. When the surgery is over and the curette needs to be cleaned and disinfected, the medical staff holds the arc-shaped rubber strip 202 on the sliding sleeve 201 and gently pushes the sliding sleeve 201 to the left. Because the sliding protrusion on the inner wall of the sliding sleeve 201 cooperates with the long strip groove on the left side of the outer surface of the handle 1, the sliding sleeve 201 can slide stably along the axial direction of the handle 1. During the process of pushing the sliding sleeve 201, the fixing plate 203 will move to the left along with the sliding sleeve 201, and the compression spring 204 will be compressed, and its elastic force will gradually increase. When the sliding sleeve 201 moves to a certain position, the sliding sleeve 201 will press the positioning cylinder 6 inward, so that the connection between the curette plate 4 and the handle 1 is released. At this time, the curette plate 4 together with the moving block 3 can be easily removed from the handle 1 to complete the disassembly operation.

[0029] In summary, this detachable uterine curette, with its sliding disassembly device 2, allows medical staff to easily separate the curette plate 4 from the handle 1 by simply pushing the sliding sleeve 201 to overcome the elasticity of the compression spring 204. This significantly reduces the force required for disassembly, making the operation more convenient and improving the ease of disassembly and replacement of the uterine curette. It also facilitates thorough cleaning and disinfection of all components, effectively reducing the risk of cross-infection.

[0030] This detachable uterine curette, through the matching of the positioning cylinder 6 and the positioning hole, and the adaptation of the moving block 3 and the inner circular cavity of the handle 1, ensures the accuracy and stability of the curette installation, enabling the curette to work more stably during the surgical procedure, thereby improving the safety and precision of the surgical operation.
