Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical saw blade technology, specifically a medical bone cutting saw blade. Background Technology
[0002] In current technologies, medical bone cutting saw blades are commonly used as core tools for bone cutting and shaping, and are widely applied in scenarios such as fracture reduction and fixation, joint replacement, and bone tumor resection. Their performance directly affects surgical efficiency and safety. Currently, many medical bone cutting saw blades used in clinical practice are made of ordinary metal materials, which exposes many technical limitations in actual operation: On the one hand, during the cutting process, the blade is prone to chipping and excessive wear due to insufficient matching of material hardness and toughness, which not only increases the risk of surgical interruption but may also produce bone fragments, leading to postoperative infection risks; on the other hand, the tooth design and cutting angle of these saw blades lack targeted optimization, making it difficult to adapt to the cutting needs of bone tissues of different densities (such as cortical bone and cancellous bone), which can easily lead to excessive damage to bone tissue, increased bleeding, and prolonged patient healing period. As orthopedic surgery moves towards minimally invasive and precise procedures, and patients demand higher levels of surgical safety and postoperative quality of life, the development of novel medical bone cutting saw blades with high hardness, high wear resistance, and low tissue damage has become a key direction for addressing clinical pain points and promoting advancements in orthopedic medical technology. It also provides an important research and development scenario for the application of related materials science and precision machining technologies in the medical field.
[0003] However, existing technologies still have shortcomings, such as the following: Existing medical bone cutting saw blades generally lack temperature monitoring capabilities. During the long-term reciprocating cutting of bone, the saw blade is prone to generating heat due to friction, which gradually accumulates. Medical staff cannot keep track of the temperature changes of the saw blade in time, which may lead to overheating of the saw blade and damage to the bone and surrounding soft tissue at the surgical site, increasing the surgical risk. Utility Model Content
[0004] The purpose of this invention is to provide a medical bone cutting saw blade to solve the problem mentioned in the background art that medical bone cutting saw blades generally lack temperature monitoring functions.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A medical bone cutting saw blade includes a saw blade with a reversible color-changing temperature measuring patch inserted into the inner side of the outer wall of the saw blade. The saw blade includes a saw body with an installation groove on the outer wall of the saw body. A saw blade is formed on one side of the outer wall of the saw body. A saw tail is fixedly connected to the outer wall of one end of the saw body. A positioning hole is formed on the outer wall of the saw tail. A connecting end is fixedly connected to one side of the outer wall of the saw tail.
[0006] Preferably, the left and right sides of the inner side of the mounting groove are provided with inclined surfaces, and the inclined surfaces are slightly curved surfaces.
[0007] Preferably, a positioning groove is provided at the bottom of the middle part of the mounting groove, and the inner side of the positioning groove is used to store the reversible color-changing temperature measuring patch.
[0008] Preferably, side plates are fixedly connected to the outer walls of the top of both sides of the mounting groove, and the gaps on the lower surfaces of the side plates are used to clamp and limit the two sides of the reversible color-changing temperature measuring patch.
[0009] Preferably, the reversible color-changing temperature sensor patch includes a temperature sensor body, and the center of the temperature sensor body is provided with multiple display rings, each of which represents a different temperature.
[0010] Preferably, a temperature mark is fixedly connected to the outer wall of the temperature measuring plate, and the temperature mark is used to mark the temperature of the display ring.
[0011] Preferably, the outer wall of the temperature measuring strip is provided with a waterproof layer to prevent water or blood from penetrating into the interior of the temperature measuring strip and affecting the detection results.
[0012] Compared with the prior art, the beneficial effects of this utility model are: When the saw blade is in operation, the temperature sensing plate can accurately detect the temperature of the saw blade side. When the temperature reaches key points such as 5℃, 15℃, 25℃, and 35℃, the corresponding display circle will turn black, and the temperature can be read intuitively in conjunction with the temperature scale. This can promptly alert medical staff to changes in the saw blade temperature, avoiding damage to surrounding tissues due to overheating of the saw blade. Especially in orthopedic surgery, it can reduce the impact of thermal damage on bones and soft tissues, significantly improving surgical safety and filling the gap in current technology for temperature monitoring.

[0016] like Figure 1 As shown, a medical bone-cutting saw blade includes a saw blade 1. A reversible color-changing temperature-sensing patch 2 is inserted into the inner side of the outer wall of the saw blade 1. The saw blade 1 includes a saw body 11. An installation groove 16 is formed on the outer wall of the saw body 11. The reversible color-changing temperature-sensing patch 2 is limited by the inner side of the installation groove 16. A saw blade 12 is formed on one side of the outer wall of the saw body 11. Medical bone cutting is performed using the inner side of the saw blade 12. A saw tail 13 is fixedly connected to the outer wall of one end of the saw body 11. The saw tail 13 is for easy installation with medical instruments. A positioning hole 15 is formed on the outer wall of the saw tail 13. When the saw blade 1 is installed, it can be limited by inserting a bolt or pin into the inner side of the positioning hole 15. A connecting end 14 is fixedly connected to one side of the outer wall of the saw tail 13. The connecting end 14 is used to install and match an electric saw, so that the drive device of the electric saw can transmit power.
[0017] It should be noted that in this embodiment, by aligning the saw tail 13 with the electric saw and installing it with the drive structure of the electric saw through the positioning hole 15, the drive structure of the electric saw is activated, causing the saw body 11 to move in a linear reciprocating motion, and the saw blade 12 can be used to cut the bone.
[0018] like Figure 2 - Figure 4 As shown, inclined surfaces 161 are provided on the left and right sides of the inner side of the mounting groove 16. The inclined surfaces 161 are slightly curved to facilitate the insertion of the reversible color-changing temperature measuring patch 2 into the inner side of the positioning groove 162.
