Description

Technical Field

[0001] The utility model relates to the technical field of spinal orthopedic instruments, in particular to a novel bone scraper. Background Art

[0002] With the development of society, most jobs require the use of computers and electronic products. Long-term exposure to computers or electronic devices and lack of proper activities can easily lead to cervical spondylosis, lumbar disc herniation and other diseases. When the above diseases require surgical treatment, scrapers are usually used clinically. Bone scrapers are a medical device used in spinal surgery. They are mainly used to scrape spinal bones or soft tissues on the spine so that doctors can better access and treat vertebral bodies, intervertebral discs or other related structures.

[0003] Existing bone scrapers often need to be disinfected before use, but the disinfection of existing bone scrapers mostly requires special disinfection equipment for disinfection, which easily leads to incomplete disinfection during the disinfection process. The bone scraper itself does not have a self-disinfection structure, which is not very convenient to use. Therefore, the utility model provides a new bone scraper to solve the problems raised in the above background technology. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and proposes a new bone scraper. The bone scraper is provided with a fixed sleeve box with a brush, which is repeatedly extended and shortened by an electric telescopic rod to make the fixed sleeve box move back and forth, so as to disinfect the knife rod and the knife head. The use is more convenient, and the disinfectant water can be heated to evaporate faster after disinfection, so it is more convenient to use.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A water pump is fixedly arranged on the top surface of the device box, a water inlet pipe is fixedly arranged at the water inlet of the water pump, the water inlet pipe penetrates into the inner cavity, a telescopic tube is fixedly arranged at the water outlet of the water pump, an electric telescopic rod is fixedly arranged in the middle of the upper end surface of the device box, a fixed sleeve is fixedly arranged on the upper end of the electric telescopic rod, an annular groove is opened inside the fixed sleeve, a brush is embedded in the inner surface of the fixed sleeve, and the upper end surface of the telescopic tube penetrates to the inner bottom surface of one side of the annular groove;

[0008] The knife bar comprises a base layer, the base layer is covered with a reinforcement layer, and the reinforcement layer is covered with a corrosion-resistant layer;

[0009] Through the above technical scheme, the bone scraper is provided with a fixed sleeve box around the blade rod, the fixed sleeve box is connected to the electric telescopic rod, and a brush is provided on the inner surface of the fixed sleeve box. The disinfectant water in the inner cavity can be sent into the annular groove inside the fixed sleeve box through the telescopic tube by a water pump to soak the brush. Then, the electric telescopic rod is repeatedly extended and shortened to make the fixed sleeve box move back and forth to disinfect the blade rod and the blade head, which is more convenient to use. In addition, a heating plate is provided at the lower part of the inner part of the handle. The heating plate heats the disinfectant water in the inner cavity, so that the temperature of the disinfectant water immersed in the brush is higher. When the disinfectant water is rubbed on the blade rod and the blade head, the disinfectant water can evaporate faster, which is more convenient to use.

[0010] Furthermore, a protective cover is fixedly provided on the upper end of the device box, and through grooves are provided at the lower part of the protective cover;

[0011] Through the above technical solution, a certain protective effect can be achieved by arranging the protective cover on the electric telescopic rod and the telescopic tube, and the liquid flowing into the protective cover can be allowed to flow out by arranging the through groove.

[0012] Furthermore, a battery is fixedly arranged on the bottom surface of the device box, and a control switch is fixedly arranged in the middle of the front end surface of the device box;

[0013] Through the above technical solution, a control switch is provided to control the start and stop of the electric telescopic rod, the water pump and the heating plate.

[0014] Furthermore, a liquid inlet is provided at the lower part of the other side of the handle, and a movable sleeve of the liquid inlet is provided with a rubber plug;

[0015] Through the above technical solution, a liquid inlet is provided for adding disinfectant water.

[0016] Furthermore, the base layer is set to be made of stainless steel, the reinforcement layer is set to be made of carbon fiber, and the corrosion-resistant layer is set to be a zinc coating;

[0017] Through the above technical solution, the combination of stainless steel and carbon fiber makes the strength better. Zinc reacts with oxygen in the air to form a zinc oxide film to prevent further oxidation of the metal, which can play a good corrosion resistance role.

[0018] Furthermore, a thread groove is provided in the middle of the upper end surface of the tool rod, a screw is fixedly provided in the middle of the lower end surface of the tool head, and the screw is threadedly sleeved with the thread groove;

[0019] According to the above technical solution, the cutter head can be disassembled and replaced by providing a threaded groove at the upper end of the cutter rod and setting a screw at the lower side of the cutter head.

[0020] Furthermore, the structure of the cutter head is the same as that of the cutter bar;

[0021] Through the above technical solution, by setting the cutter head and the cutter rod mechanism the same, the cutter head and the cutter rod both have good reinforcement performance and corrosion resistance.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model proposes a novel bone scraper, which is provided with a fixed sleeve box around the blade rod, the fixed sleeve box is connected with an electric telescopic rod, and a brush is provided on the inner surface of the fixed sleeve box.
