Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a tibial soft tissue scraper. Background Art

[0002] Debridement is a key step in the treatment of open fractures. Its purpose is to transform the open wound into a nearly sterile wound surface, laying a good foundation for subsequent tissue repair and fracture treatment. This process requires the surgeon to carefully remove all necrotic and inactive tissue, including subcutaneous fat, muscle, and foreign matter and bone fragments at the fracture end, while carefully protecting major blood vessels and nerves and repairing them when necessary. However, traditional debridement surgery presents many challenges, especially when using a scalpel to debride the fracture end. The surgeon not only needs to have high skills and extensive experience to accurately remove contaminated tissue and avoid damaging healthy tissue and important blood vessels and nerves, but also needs to control the scraping depth in deep or restricted areas to prevent excessive damage to the bone marrow cavity. These challenges highlight the importance of fine surgical skills and the reliance on the surgeon's professional judgment in complex surgical scenarios. To this end, a tibial soft tissue scraper was designed to effectively address the above problems. Utility Model Content

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0019] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] The following is combined with Figure 1-4 The utility model is further described in detail:

[0022] like Figure 1 As shown, the utility model provides a tibial soft tissue scraper, comprising a handle 1 and a blade head 2, wherein the blade head 2 comprises a horizontal portion 21 and a curved portion 22, wherein one end of the horizontal portion 21 is detachably connected to the handle 1, and the other end is connected to the curved portion 22, and the blade head 2 is integrally formed;

[0023] Specifically, the handle 1 is cylindrical and is provided with a pointing slot 121 on the side of the handle 1 opposite the curved portion 22. The structural design of the pointing slot 121 enables rapid positioning of the blade 2, solving the problem of being unable to identify the direction of the blade 2 toward bone tissue when the blade 2 is inserted into tissue in actual application.

[0024] Reference Figure 2 The handle 1 includes a gripping portion 11 and a connecting portion 12. The gripping portion 11 has a smaller diameter than the connecting portion 12, and a pointing slot 121 is located on the connecting portion 12. A gripping slot 111 is provided on the opposite side of the gripping portion 11. This arrangement improves the doctor's grip comfort and prevents the gripping slot 111 from rotating during operation.

[0025] In this embodiment, the horizontal portion 21 and the connecting portion 12 are connected by a pin 122, or by bolts, screws, etc. Through the independent structural design of the cutter head 2, the purpose of adapting different types of blades 23 for scraping in different scenarios is achieved, which solves the need for flexible configuration according to different fracture locations or parts in actual applications.

[0026] Reference Figure 3 A pair of blades 23 are symmetrically spaced at the front end of the curved portion 22. The front ends of the blades 23 protrude from the curved portion 22 and the front ends of the two blades 23 gradually approach each other, so that the blades 23 contact the bone tissue surface in a triangular shape. A cutting edge 24 is formed at the top of the blade 23, and there is an inclination angle between the cutting edge 24 and the blade 23. The triangular structure formed by the two blades 23 and the cutting edge 24 works together to achieve cutting and sufficient separation of the bone tissue surface, solving the problem of insufficient scraping in actual applications.

[0027] Reference Figure 4 The curved portion 22 is provided with an arcuate groove 26 at the front end, located between the blades 23. The combined action of the arcuate groove 26 and the blades 23 achieves post-anastomosis contact and effective removal of damaged tissue from the tibia, resolving the practical issue of difficulty in removing damaged tissue due to the limitations of the scraper's shape. The structural design of the arcuate groove 26 effectively guides the scraper during the removal process, resolving the practical issue of incomplete removal after blind scraping.

[0028] In this embodiment, the front ends of the blades 23 gradually approach each other to form a chip discharge opening 25, which is located at one end of the arc-shaped groove 26. The structural design of the chip discharge opening 25 enables the rapid and convenient discharge of foreign matter after scraping, and effectively separates clean tissue from damaged tissue in practical applications.

[0029] The scraper operation steps include holding the handle 1, extending the blade head 2 along one side to one end of the tibia fracture until the triangular surface formed by the blade 23 abuts the bone tissue surface, and pulling the handle 1 along the tibia surface. At this time, the blade 23 slides along the tibia, and the sliding process removes the damaged tissue on the tibia surface. Repeat the sliding until one end is cleaned. Similarly, place the blade head 2 on the broken tibia surface at the other end. After the cleaning is completed, withdraw the tibial soft tissue scraper.

[0030] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
