[0034] The grip assembly 2 includes a first inner rod 22 fixedly connected to the bottom cover 12 via a mounting block 21, a second inner rod 23 sleeved on the outer wall of the first inner rod 22, and a sleeve rod 24 sleeved on the outer wall of the second inner rod 23. The mounting block 21 is fixedly connected to the bottom of the bottom cover 12. The top end of the first inner rod 22 is fixedly connected to the bottom center position of the mounting block 21. The bottom end of the first inner rod 22 is threaded onto the inner side of the second inner rod 23. A rotating block 231 is sleeved on the upper part of the outer wall of the second inner rod 23. The lower part of the outer wall of the second inner rod 23 is threaded onto the inner side of the sleeve rod 24.

[0035] Among them, such as Figure 3 As shown, a display screen 111 is embedded below the front end face of the scraper bar 11. The display screen 111 is electrically connected to the temperature sensor 15. Scale lines 112 are etched at equal intervals on the front end face of the scraper bar 11, and the scale lines 112 are located above the display screen 111.

[0036] Specifically, the display screen 111 is electrically connected to the temperature sensor 15, so that the temperature sensor 15 detects the temperature of the curette 11 and displays it on the display screen 111, which makes it convenient for medical staff to control the temperature of the curette 11 and the curette head 3 and keep it within a suitable temperature range. At the same time, the scale line 112 makes it convenient for medical staff to insert the curette head 3 into the inside of the uterus in a quantitative manner.

[0037] Among them, such as Figure 2 As shown, a protective sleeve 16 is fitted on the outer wall of the scraper bar 11. A first through hole 161 and a second through hole 162 are respectively opened below and above the front end face of the protective sleeve 16. Specifically, the protective sleeve 16 is made of medical rubber material. The protective sleeve 16 is designed to prevent the scraper bar 11 from scratching the patient. At the same time, the first through hole 161 and the second through hole 162 make it convenient for medical staff to observe the display screen 111 and the scale line 112.

[0038] Among them, such as Figure 4 As shown, a mounting groove 121 is provided at the center of the bottom of the bottom cover 12. A battery 122 is fixedly connected to the top of the inner side of the mounting groove 121. A cover plate 123 is snapped into the lower opening of the mounting groove 121. A button 124 is provided at the center of the front end face of the bottom cover 12.

[0039] Specifically, the mounting slot 121 is used to install the battery 122, which powers electronic components such as the radiant tube 13 and the temperature sensor 15. The cover plate 123 protects the battery 122. Meanwhile, the button 124 controls the electrical connection between the battery 122 and the radiant tube 13, thereby controlling the opening or closing of the radiant tube 13.

[0040] Among them, such as Figure 5 As shown, the top four sides of the mounting block 21 are fixedly connected with a locking plate 211, and the inner side of the locking plate 211 is respectively connected to the outer side of the bottom cover 12. Specifically, the locking plate 211 is made of elastic material. The locking plate 211 realizes the locking between the mounting block 21 and the bottom cover 12, which facilitates the installation and removal of the two.

[0041] Among them, such as Figure 5 As shown, anti-slip sleeves 241 are adhered to the outer walls of both the rotating block 231 and the sleeve rod 24. Specifically, the anti-slip sleeves 241 increase the coefficient of friction on the outer surfaces of the rotating block 231 and the sleeve rod 24, thereby facilitating the rotation of the second inner rod 23 and the sleeve rod 24.

[0042] Among them, such as Figure 6As shown, the bottom of the scraper head 3 is fixedly connected to an internally threaded tube 31, which is threaded onto the top of the scraper rod 11. Specifically, the internally threaded tube 31 enables the threaded connection between the scraper head 3 and the scraper rod 11, thereby facilitating the installation and removal of the scraper head 3.

[0043] Based on the aforementioned uterine curette, during use, first adjust the length of the handle assembly 2 according to the usage habits of medical staff. Hold the mounting block 21 and the rotating block 231 respectively, and apply external force to the rotating block 231. This causes the rotating block 231 to drive the second inner rod 23 to rotate relative to the first inner rod 22. Under the effect of the threaded connection between the first inner rod 22 and the second inner rod 23, the second inner rod 23 moves relative to the first inner rod 22, thereby changing the distance between the first inner rod 22 and the second inner rod 23. Then, hold the rotating block 231 and the sleeve rod 24 respectively, and simultaneously apply external force to the sleeve rod 24. This causes the sleeve rod 24 to rotate relative to the second inner rod 23. Under the effect of the threaded connection between the second inner rod 23 and the sleeve rod 24, the sleeve rod 24 moves relative to the second inner rod 23, achieving... The distance between the second inner rod 23 and the sleeve rod 24 is adjusted to complete the length adjustment of the handle assembly 2. Then, the medical staff holds the handle assembly 2 and presses the button 124, which makes the electric radiation tube 13 start working. The electric radiation tube 13 heats the inside of the scraper rod 11. The heat is transferred to the scraper rod 11 through the heat transfer plate 14. At the same time, the temperature of the scraper rod 11 is detected by the temperature sensor 15. When the temperature of the scraper rod 11 reaches the preset value range, the electric radiation tube 13 is turned off by pressing the button 124. This achieves the temperature adjustment of the scraper rod 11 and the scraper head 3. Finally, the scraper head 3 is inserted into the patient's uterus, and the scraper rod 11 drives the scraper head 3 to move in the patient's uterus, so that the scraper head 3 scrapes the patient's endometrium.

[0044] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
