Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, and particularly relates to a bone curet with real-time flow control. BACKGROUND

[0002] In the field of medical apparatus and instruments, especially in orthopedic surgery, the curet is an important surgical tool. It is mainly used in orthopedic surgery, especially in the surgical treatment of diseases such as bone infection, soft tissue infection, bone necrosis, and bone tumor. It is used to remove pus, microbial membrane, bone lesion tissue, dead bone, granulation tissue, and scar tissue, etc., providing important support for the success of the operation. By removing necrotic bone, inflammatory granulation tissue, pus, and bone tumor cells, the cause of the disease can be fully removed, improving the patient's recovery possibilities.

[0003] Traditional curet structures are simple, and may be laborious and not thorough during operation. The curet head and handle are simply connected by a ratio of hard metal, which is not convenient for operation in a narrow medullary cavity during surgery, and the direction of the curet cannot be changed as needed. There is no lumen connection between the traditional curet head and handle, so the negative pressure suction device cannot be connected, and the pus and other tissues scraped during the operation cannot be cleaned in time. Modern improved curet structures are more complex, such as having a lighting device and adjustable rotary bone scraping blades, to adapt to different surgical needs. The operation is more convenient, and the necrotic bone tissue can be removed more accurately, improving the efficiency of the operation. Some curets also have multifunctionality, such as being equipped with a bone grafting device and a bone hammer, providing a more comprehensive solution for surgery. With the continuous development of medical technology, the structure and function of the curet are constantly improving and perfecting.

[0004] The patent with the application number CN202022786675.7, the application date of November 26, 2020, and the name of a flow guide bone curet, has a liquid accumulator and a movable pull rod that can absorb effusion and blood, which meets the needs of removing lesions and discharging liquids. However, air can only be discharged when pressed, and liquid and debris are sucked when the hand is released. When the liquid in the accumulator reaches a certain level, backflow may occur. In addition, the curet head and handle are of an integrated structure, making it difficult to reach any space in the bone cavity. SUMMARY

[0005] In view of the above problems of the curet, such as incomplete removal of lesions, liquid backflow, and continuous operation, the utility model provides a bone curet with real-time flow control.

[0006] The technical solution adopted by the utility model to solve the above technical problems is:

[0007] The application discloses a bone curet which can control flow in real time, and belongs to the field of medical equipment.

[0008] Further, the control device comprises a control button, a counterforce spring, a flow control valve body and a sealing plate.

[0009] Further, the control button is a cylinder, the side surface of the control button is provided with a guide rail, the mounting hole is provided with a guide groove matched with the guide rail, and the mounting hole is provided with a limiting table for limiting the control button.

[0010] Further, the sealing plate is fixedly connected with the handle through screws.

[0011] Further, the handle is fixedly connected with the connecting pipe through a pin shaft.

[0012] Further, the connecting pipe and the air suction pipeline are communicated through an air pipe connector, so that air leakage at the connecting position of the connecting pipe and the air suction pipeline is avoided.

[0013] Further, the connecting pipe is made of metal, and the metal has a certain hardness, so that the connecting pipe can be used to scrape a bone cavity.

[0014] Further, the material of the flexible metal hose comprises 316 stainless steel, memory alloy and nickel-titanium alloy, and the materials have certain hardness and flexibility, so that the flexible metal hose can be used to process dirt or foreign matters in a bone cavity.

[0015] The control device in the present application can adjust the flow rate of the fluid in the suction pipe and stabilize the pressure in the pipe. By reasonable flow rate adjustment, pressure fluctuations caused by excessive or insufficient flow rate in the pipe can be avoided. On the other hand, it also has the effect of preventing liquid backflow. The spatula head is threadedly connected with the flexible metal hose. The purpose is that the shape and size of the spatula head may be different according to the specific needs of the surgery and be replaced to meet the scraping needs of different surgical sites. The flexible metal hose provides a flexible range of motion for the spatula head. It allows the surgeon to adjust the position and angle of the spatula head as needed during the operation in order to better contact and scrape the surgical site. The vacuum system is the power source in the spatula system, which generates a negative pressure effect to drive the operation of the suction pipe. Through the action of the vacuum system, the suction pipe can smoothly suck away the waste generated at the surgical site, providing important support for the smooth progress of the operation. The vacuum system usually has stable and reliable performance and can continuously provide the required negative pressure effect during the operation. At the same time, its design also takes into account the energy-saving and environmental protection needs to reduce energy consumption and waste emission during the operation.
