Description

Technical Field

[0001] This utility model belongs to the field of orthopedic surgical instrument technology, specifically relating to a bone wax application device. Background Technology

[0002] Bone wax is a commonly used hemostatic product by doctors, primarily used in endoscopic lumbar interbody fusion surgery to stop bleeding from the bone wound. Currently, bone wax is solid at room temperature and packaged in sheets. Its soft texture allows it to be reshaped by hand. The conventional method is to pick up the bone wax with a bent metal rod, or under sterile conditions, roll it into a ball, place it on the rod, and then squeeze it to apply it to the bone wound. However, endoscopic lumbar interbody fusion surgery involves aqueductal insertion through a small channel into the spine. Using a conventional bent metal rod, the bone wax may be blocked by skin, ligaments, muscles, or other connective tissues along the way, preventing timely application to the wound surface. There is also a possibility of detachment during the procedure. Furthermore, the blocked or detached bone wax cannot remain in other parts of the body; medical staff must locate and remove it, increasing the operation time. Summary of the Invention

[0003] The purpose of this invention is to provide a bone wax application device that is easy to operate and has a simple structure.

[0004] The bone wax application device provided by this utility model includes an operating rod and an application head; The operating lever is a slender rod with its head end connected to the applicator head. The applicator head includes a base, side brushes, and a hard scraper. The base is a square rigid plate; The side brush has three pieces, which are vertically arranged on the three sides of the base. The side brush is made of soft medical silicone material, and the inner side cross-section is bulging in an arc shape. The hard scraper is located on the fourth side of the base and is an extension of the base.

[0005] In this invention, the bottom surface of the base is provided with a spherical connector, and the head end of the operating rod has a multi-claw structure: multiple strip-shaped fixing rods are arranged parallel and vertically around the head end face of the operating rod, and spherical cutouts are provided on the inner side of the arranged fixing rods. The ball head of the spherical connector can be inserted into the spherical cutouts in the arranged fixing rods to form an adjustable applicator head; Figure 2 As stated above.

[0006] In this invention, the base and the hard scraper are made of the same material and are integrally formed.

[0007] In use, the surgeon places the bone wax on the base within the space enclosed by the three side brushes. Then, using the operating rod, the applicator inserts the applicator head through ligaments, muscles, and other tissues into the surgical area. The side brushes prevent the bone wax from contacting and remaining on the ligaments and muscles. The ball-head rotating base allows for better adjustment of the side brush position during insertion, ensuring that the side brushes are positioned at the end of the insertion direction, thus preventing the bone wax from contacting the ligaments, muscles, and other tissues. When the bone needs to be applied, the operating rod can be rotated to gently press the soft side brushes against the bone, allowing the bone wax to contact the bone. The hard scraper then spreads the wax evenly onto the bone wound surface.

[0008] The advantages of this invention are its simple structure, low cost, simple operation, ability to save surgical time, and ability to ensure even application of bone wax. Attached Figure Description

[0013] This utility model includes an operating rod 1 and an application head 2; the operating rod 1 is a slender cylindrical rod, with its head end connected to the application head 2; as shown... Figure 1 As shown.

[0014] The applicator head 2 includes a base 3, a side brush 4, and a hard scraper 5; The base 3 is a square rigid base plate; the side brushes 4 consist of three pieces, which are respectively vertically arranged on the three sides of the base 3. The side brushes 4 are made of soft medical silicone material, which can be deformed by compression. The inner side cross-section is bulging in an arc shape for better coating of bone wax; the rigid scraper 5 is arranged on the fourth side of the base 3 and is an extension of the base. It can be integrally molded from the base 3; the corners of the base 3 and the rigid scraper 5 are rounded to protect human muscles and soft tissues from being scratched. The hard scraper 5 is made of a slightly hard plastic material, such as polypropylene; the applicator head 2 is made using a two-material injection molding process.

[0015] The bottom surface of the base 3 is provided with a ball connector 7, and the head end of the operating lever 1 has a multi-claw structure. Multiple strip-shaped fixing rods 6 are arranged parallel to each other and vertically around the head end face of the operating rod. The inner surface of the surrounding fixing rods 6 has a spherical cutout 8. The ball head of the spherical connector 7 can be inserted into the spherical cutout 8 within the surrounding fixing rods, forming an adjustable-angle applicator head 2. Figure 2 As stated above.

[0016] In use, the surgeon places the bone wax on the base within the space enclosed by the three side brushes. Then, using the operating rod, the applicator inserts the applicator head through ligaments, muscles, and other tissues into the surgical area. The side brushes prevent the bone wax from contacting and remaining on the ligaments and muscles. The ball-head rotating base allows for better adjustment of the side brush position during insertion, ensuring that the side brushes are positioned at the end of the insertion direction, thus blocking the bone wax from contacting ligaments, muscles, and other tissues. When the bone area to be applied is reached, the operating rod can be rotated to gently press the soft side brushes against the bone, allowing the bone wax to contact the bone. The hard scraper then scrapes and spreads the wax evenly onto the bone wound surface.
