Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a toothed medical scraper. Background Technology

[0002] In the field of medical devices, medical curettes, as a basic surgical tool, play a vital role in many medical branches such as general surgery, maxillofacial surgery, and dermatological surgery. Traditional medical curettes have a relatively simple design, mainly consisting of a handle and a smooth curette head, used to scrape away foreign objects, diseased tissue, or clean surgical sites. With the continuous development of medical technology, the materials, shapes, and functions of medical curettes have been significantly improved to meet the needs of more complex and delicate surgeries.

[0003] However, although traditional medical curettes perform well in most surgeries, their efficiency and effectiveness are often unsatisfactory in complex procedures such as sinus tract removal, cyst wall destruction and removal, and skin infection foci removal in maxillofacial and dermatological surgery. This is mainly because the smooth curette head is difficult to effectively grasp and scrape away foreign bodies and lesions attached to the skin or deep tissues, leading to repeated operations during the procedure. This not only prolongs the operation time but may also increase patient pain and postoperative recovery risks. Therefore, improvements to the curette are needed. Utility Model Content

[0004] The purpose of this invention is to provide a toothed medical curette to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A toothed medical curette includes:

[0007] Handle;

[0008] Connecting rods are inserted into both sides of the inner wall of the handle. An installation rod is fixedly connected to the front end of the connecting rod, and a scraper is fixedly connected to the front end of the installation rod. Multiple connecting teeth are fixedly connected to the surface of the scraper.

[0009] Preferably, the top two sides of the handle are provided with connecting grooves, and the two sides of the connecting grooves are provided with limiting slots.

[0010] Preferably, the top of the connecting rod is provided with an installation groove, the inner wall of the installation groove is rotatably connected to a retaining plate, the inner side of the retaining plate is connected to a compression spring, and the surface of the retaining plate is inserted into the inner wall of the limiting groove.

[0011] Preferably, a mounting frame is fixedly connected to the bottom of the connecting rod, and a roller is rotatably connected to the inner wall of the mounting frame, with the surface of the roller slidably connected to the inner wall of the handle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) With the setting of handle, connecting rod, mounting rod, curette and connecting teeth, when in use, multiple connecting teeth are set on the surface of the curette. In general surgery, maxillofacial surgery and dermatological surgery, the curette and connecting teeth can easily handle complex surgeries such as skin sinus scraping, cyst wall destruction and removal and skin infection foci scraping. Its fine connecting tooth design allows the curette to scrape diseased tissue more deeply, reduce residue and improve treatment effect. At the same time, the curette also has good guidance and precision, which can accurately locate the surgical site, reduce damage to surrounding healthy tissues, and thus improve patient comfort.

[0015] (2) With the setup of handle, limiting slot, connecting rod, clamping plate, compression spring, roller and light, when in use, the staff squeezes the two clamping plates towards the middle, so that the compression spring in the middle of the two clamping plates squeezes and pulls the two clamping plates out of the limiting slot, and then makes it easy for the two clamping plates to slide from the connecting slot, thereby moving the connecting rod. When the connecting rod moves to the appropriate position, the two clamping plates are released, so that the compression spring pops the two clamping plates to the sides and inserts the clamping plates into the limiting slot for limitation, thereby making it easy to fix the connecting rod, and thus easy to adjust the length of the scraper. The roller slides and is connected to the inner wall of the handle, thereby making it easy for the connecting rod to move stably. The light makes it easy for medical staff to see the internal condition of the body during treatment, thus achieving the effect of easy and stable adjustment of the scraper length and easy lighting for viewing.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figures 1 to 4 As shown, a toothed medical curette includes:

[0024] Handle 1;

[0025] Both sides of the inner wall of the handle 1 are connected to connecting rods 2. The front end of the connecting rod 2 is fixedly connected to the mounting rod 3. The front end of the mounting rod 3 is fixedly connected to the curette 4. Multiple connecting teeth 5 are fixedly connected to the surface of the curette 4. In general surgery, maxillofacial surgery and dermatological surgery, the curette 4 with connecting teeth 5 can easily handle complex surgeries such as skin sinus scraping, cyst wall destruction and removal, and skin infection foci scraping. Its fine design of connecting teeth 5 allows the curette 4 to scrape diseased tissue more deeply, reduce residue, and improve treatment effect. At the same time, the curette 4 also has good guidance and precision, which can accurately locate the surgical site and reduce damage to surrounding healthy tissues.

[0026] Example 2:

[0027] Please see Figures 1 to 4As shown, the top of the handle 1 has connecting grooves 6 on both sides, and limit slots 7 are provided on both sides of the connecting grooves 6. The top of the connecting rod 2 has an installation groove 8. The inner wall of the installation groove 8 is rotatably connected to a clamping plate 9. A compression spring 10 is connected to the inner side of the clamping plate 9, and the surface of the clamping plate 9 is inserted into the inner wall of the limit slot 7. When the operator presses the two clamping plates 9 towards the center, the compression spring 10 in the center of the two clamping plates 9 is compressed, causing the two clamping plates 9 to be pulled out of the limit slot 7, thus facilitating the sliding of the two clamping plates 9 from the connecting groove 6. This moves the connecting rod 2, and when the connecting rod 2 moves to the appropriate position, the two clamping plates 9 are released, causing the compression spring 10 to pop the two clamping plates 9 out to the sides, thus locking the handle 2. Plate 9 is inserted into the limiting slot 7 for limiting, thereby facilitating the fixing of connecting rod 2 and adjusting the length of scraper 4. A mounting frame 11 is fixedly connected to the bottom of connecting rod 2. A roller 12 is rotatably connected to the inner wall of mounting frame 11, and the surface of roller 12 is slidably connected to the inner wall of handle 1. The roller 12 is slidably connected to the inner wall of handle 1, thereby facilitating the stable movement of connecting rod 2. A light 13 is fixedly connected to the inner wall of mounting rod 3, which facilitates medical personnel to observe the internal condition of the body during treatment. A transparent baffle 14 is fixedly connected to the surface of mounting rod 3, and the back of transparent baffle 14 overlaps the surface of light 13, which provides protection for light 13.

[0028] Example 3:

[0029] Please see Figures 1 to 4 As shown, in general surgery, the toothed medical curette has demonstrated its unique advantages. For example, when performing abdominal wall hernia repair, doctors need to remove the fluid and adhesions in the hernia sac. Traditional curettes often have difficulty completely scraping away these small and complex tissues, while the toothed medical curette, with its finely designed connecting teeth, can easily scrape away all adhesions in the hernia sac, ensuring the cleanliness of the surgical site and providing a good surgical environment for subsequent hernia repair.

[0030] In maxillofacial surgery, toothed medical curettes also play an important role. Taking jaw cyst removal as an example, doctors need to thoroughly remove the cyst wall while protecting the surrounding important structures. Traditional curettes are often difficult to control when scraping the cyst wall, and are prone to damaging the surrounding healthy tissue. However, toothed medical curettes can accurately scrape the cyst wall with their fine scraping teeth and excellent guidance, while avoiding damage to the surrounding tissue, thus ensuring the precision and safety of the operation.

[0031] In dermatological surgery, the use of toothed medical curettes is even more widespread. Taking the curettage of skin sinuses as an example, skin sinuses often extend deep into the subcutaneous tissue. Traditional curettes are difficult to scrape away the diseased tissue inside the sinuses, while toothed medical curettes can thoroughly remove foreign bodies and diseased tissue inside the sinuses due to their ability to scrape deeply, thus promoting wound healing. In addition, in surgeries such as skin cyst excision and curettage of skin infection foci, toothed medical curettes can also ensure the smooth progress of the surgery due to their high scraping efficiency and precision.

[0032] In conclusion, the toothed medical curette 4 has significant application value in oral and dental surgery. Its precise scraping ability and easy-to-use design allow doctors to perform treatments more effectively, improving treatment outcomes and patient comfort. During use, doctors should select the appropriate scraping force and angle according to the specific application scenario and surgical needs, and ensure the curette 4 is clean and sterile.

[0033] Working principle: In oral surgery, a curette 4 with connecting teeth 5 is used to enhance the scraping effect or facilitate specific types of operations. It is used to probe the alveolar socket deep within the extraction socket, scraping away tartar, dental fragments, bone fragments, inflammatory tissue, granulomas, dental cysts, and other foreign bodies. Additionally, in dental surgery, it can be used to clean and scrape away residual or diseased tissue at the surgical site. The operator presses the two retaining plates 9 towards the center, causing the compression spring 10 in the middle of the two retaining plates 9 to compress, pulling the two retaining plates 9 out of the limiting slot 7, thus facilitating the two retaining plates 9 from the connecting slot. The connecting rod 2 is moved by sliding in the middle 6. When the connecting rod 2 is moved to the appropriate position, the two clamping plates 9 are released, so that the compression spring 10 pops the two clamping plates 9 to the sides and inserts the clamping plates 9 into the limiting groove 7 for limiting. This makes it easier to fix the connecting rod 2 and then adjust the length of the scraper 4. The roller 12 is slidably connected to the inner wall of the handle 1, which makes it easier for the connecting rod 2 to move stably. The staff turns on the power of the lighting lamp 13. The lighting lamp 13 makes it easier for medical staff to see the condition inside the oral cavity during the treatment. The lighting lamp 13 is protected by the transparent baffle 14.
