Description

Technical Field

[0001] This utility model belongs to the field of curettage instrument technology, specifically a curettage instrument. Background Technology

[0002] A dilation and curettage (D&C) procedure involves using a metal dilator to open the cervix so that a curette can be inserted into the uterus to scrape the endometrium. This D&C procedure is used to obtain biopsies, diagnose endometrial abnormalities, or treat incomplete abortions. The curette is a commonly used instrument in modern gynecological surgery, mainly used to remove tissue remaining in the uterine cavity after an incomplete abortion, to help the uterus repair itself, and to reduce the possibility of bleeding or infection.

[0003] A search revealed a gynecological curettage device with announcement number CN220193131U. This utility model provides a gynecological curettage device, including a first adjusting rod, a second adjusting rod slidably installed inside the first adjusting rod, a curettage spoon installed at one end of the second adjusting rod, a gripping block installed at one end of the first adjusting rod, a first spring installed inside the fixing hole, and a first locking pin installed at one end of the first spring.

[0004] The aforementioned curettage instrument is designed with an adjustment mechanism. When treating different patients, the length of the curettage instrument can be adjusted. First, the second adjustment rod is pulled and slides through the adjustment hole inside the first adjustment rod. During this process, the inner wall of the first adjustment rod presses against the first locking pin, causing it to retract into the fixing hole via the first spring. This also fixes the length of the first and second adjustment rods. This allows medical staff to easily adjust the curettage instrument, improving their work efficiency. However, the following problems still exist:

[0005] Current curettage instruments scrape away the endometrium or lesions through the scraping head, serving only as a scraping tool and unable to simultaneously perform surgical treatment and postoperative repair. Furthermore, while these instruments utilize spring force to fix the lengths of the first and second adjustment rods via locking pins, the distance between the locking pins in actual use prevents precise length adjustment.

[0006] Therefore, a curettage instrument is proposed to address the above problems. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Specific implementation examples are given below.

[0030] Please see Figures 1-3 This utility model provides a technical solution: a curettage device, including a handle 1, a length adjustment mechanism 2 on the left side of the handle 1, a scraper head installation mechanism 3 on the left side of the length adjustment mechanism 2, and a scraper head 4 on the left side of the scraper head installation mechanism 3. The scraper head 4 is used for scraping inside the uterus. The scraper head installation mechanism 3 is used for installing and removing the scraper head 4. The length adjustment mechanism 2 is used to adjust the length of the curettage device. The scraper head 4 includes a fixing ring 401, an elastic ring 402 is fixedly connected to the top of the fixing ring 401, and a medicated sponge 403 is fixedly connected between the fixing ring 401 and the elastic ring 402.

[0031] The above method involves placing the scraping head 4 in a medicine that promotes tissue healing during use. The medicine is absorbed by the medicated sponge 404. The scraping head 4 is then inserted into the patient's uterus through the handle 1 to perform the scraping operation. During scraping, the elastic ring 402 is compressed by pressure, causing the medicated sponge 404 to release the drug factors and promote the healing of the tissue at the scraped site.

[0032] Furthermore, such as Figure 1 , Figure 2 and Figure 4As shown, the length adjustment mechanism 2 includes a movable knob 201 and a first support rod 202. The movable knob 201 is fixedly connected to the left side of the handle 1. A connecting shaft 203 is fixedly connected to the left side of the movable knob 201. A support screw 204 is fixedly connected to the left side of the connecting shaft 203. A second support rod 206 is threadedly connected to the left side of the support screw 204. Limiting sliders 207 are symmetrically arranged on the upper and lower sides of the outer wall of the second support rod 206. Limiting sliders 207 are symmetrically arranged on the upper and lower sides of the inner wall of the first support rod 202. The slide 205 and length adjustment mechanism 2 also include a fixed toothed ring 208, the top of which is engaged with a locking toothed block 209, and the top of the locking toothed block 209 is fixedly connected to a pull rod 2010. The pull rod 2010 is slidably connected to the first support rod 202, and a first fixing spring 2011 is sleeved on the outside of the pull rod 2010. The locking toothed block 209 is elastically connected to the first support rod 202 through the first fixing spring 2011. The left side of the second support rod 206 is fixedly connected to the scraper mounting mechanism 3.

[0033] Through the above scheme: In use, pulling the lever 2010 causes the locking tooth block 209 to move upward, and rotating the handle 1 causes the movable knob 201 to rotate. Since the movable knob 201 is fixedly connected to the connecting shaft 203, and the connecting shaft 203 is fixedly connected to the support screw 204, the support screw 204 rotates under the action of the connecting shaft 203. Thus, under the action of the thread, the second support rod 206 is pushed to move along the limiting slide groove 205 according to the limiting slider 207, and the support rod is adjusted to a suitable length. At this time, the lever 2010 is released. Since the locking tooth block 209 is elastically connected to the first support rod 202 through the first fixed spring 2011, the locking tooth block 209 is pushed to mesh with the fixed tooth ring 208 under the elastic force of the first fixed spring 2011, thereby fixing the movable knob 201 and completing the length adjustment of the curettage device.

[0034] Furthermore, such as Figure 1 , Figure 2 and Figure 5As shown, the scraper head mounting mechanism 3 includes a mounting post 301 and a mounting screw 303. A mounting hole is provided on the inner wall of the left side of the second support rod 206. The mounting post 301 is slidably connected to the second support rod 206 through the mounting hole. A movable block 302 is fixedly connected to the left side of the mounting screw 303. A screw sleeve block 305 is threadedly connected to the outside of the mounting screw 303. A second fixing spring 304 is connected to the left side of the screw sleeve block 305. The left side of the second fixing spring 304 is fixedly connected to the mounting post 301. The screw sleeve block 305 is elastically connected to the mounting post 301 through the second fixing spring 304. Movable rods 306 are movably pinned to the upper and lower sides of the outer wall of the screw sleeve block 305. Mounting inserts 307 are movably pinned to the ends of the two movable rods 306 away from the screw sleeve block 305. Sliding grooves are symmetrically provided on the upper and lower sides of the inner wall of the mounting hole. Both mounting inserts 307 are slidably connected to the mounting post 301 through the sliding grooves. The movable block 302 is fixedly connected to the scraper head 4.

[0035] Through the above scheme: In use, rotating the scraper head 4 drives the movable block 302 to rotate. Since the movable block 302 is fixedly connected to the mounting screw 303, the mounting screw 303 rotates accordingly. Under the action of the thread, the screw sleeve 305 is pushed to the left along the mounting screw 303, squeezing the second fixing spring 304. Since the movable rod 306 is movablely pinned to the screw sleeve 305 and the mounting insert 307 respectively, when the screw sleeve 305 moves, under the action of the movable rod 306, it pulls the mounting inserts 307 on both sides closer to each other, thereby causing the mounting inserts 307 to leave the slot and pull out the mounting post 301, thus completing the disassembly of the scraper head 4. When installing the scraper head 4, the mounting post 301 is directly inserted into the mounting hole. Since the screw sleeve 305 is elastically connected to the mounting post 301 through the second fixing spring 304, under the elastic force of the second fixing spring 304, the mounting inserts 307 on both sides are pushed away from each other and inserted into the slot, thus completing the installation of the scraper head 4.

[0036] Working principle:

[0037] First, during use, rotating the scraper head 4 causes the movable block 302 to rotate. Since the movable block 302 is fixedly connected to the mounting screw 303, the mounting screw 303 rotates accordingly. Under the action of the thread, the screw sleeve 305 is pushed to the left along the mounting screw 303, squeezing the second fixing spring 304. Since the movable rod 306 is movably pinned to the screw sleeve 305 and the mounting insert 307 respectively, when the screw sleeve 305 moves, under the action of the movable rod 306, it pulls the mounting inserts 307 on both sides closer to each other, thereby causing the mounting inserts 307 to leave the slot and pull out the mounting post 301, thus completing the disassembly of the scraper head 4. When installing the scraper head 4, the mounting post 301 is directly inserted into the mounting hole. Since the screw sleeve 305 is elastically connected to the mounting post 301 through the second fixing spring 304, under the elastic force of the second fixing spring 304, the mounting inserts 307 on both sides are pushed away from each other and inserted into the slot, completing the installation of the scraper head 4.

[0038] Secondly, during use, the scraping head 4 is placed in a medicine that promotes tissue healing. The medicine is absorbed by the medicated sponge 404. The scraping head 4 is then inserted into the patient's uterus through the handle 1 to perform the scraping operation. During scraping, the elastic ring 402 is compressed by pressure, causing the medicated sponge 404 to release the drug factors and promote the healing of the tissue at the scraped site.

[0039] Finally, during use, pulling the lever 2010 causes the locking tooth block 209 to move upward, and rotating the handle 1 causes the movable knob 201 to rotate. Since the movable knob 201 is fixedly connected to the connecting shaft 203, and the connecting shaft 203 is fixedly connected to the support screw 204, the support screw 204 rotates under the action of the connecting shaft 203. Thus, under the action of the thread, the second support rod 206 is pushed to move along the limiting slide groove 205 according to the limiting slider 207, adjusting the support rod to a suitable length. At this time, the lever 2010 is released. Since the locking tooth block 209 is elastically connected to the first support rod 202 through the first fixed spring 2011, the locking tooth block 209 is pushed to mesh with the fixed tooth ring 208 under the elastic force of the first fixed spring 2011, thereby fixing the movable knob 201 and completing the length adjustment of the curettage device.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
