Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to the technical field of cleaning and spreader devices for surgical instruments such as rongeurs. Background Art

[0002] Rongeurs can be divided into: double joint rongeurs, olecranon rongeurs, etc., which are usually used for fractures, cartilage damage, muscle rupture and other problems in surgical treatment. Its main feature is that it can be flexible and soft during the treatment process, and it is easy to grasp and treat damaged tissues. It can achieve multiple functions such as cutting, biting, and fixation, and can reduce surgical risks and patient pain. It is widely used in orthopedics, oral and maxillofacial surgery, and skull, face, and small parts surgery. There are strict requirements for the cleaning of rongeurs. After the operation, there will be residual tissue or bone debris in the rongeurs, and the rongeurs cannot be opened automatically when they are cleaned on the machine, and tools are needed to fix them. There are two main types of fixing tools currently used: 1. Rubber bands, advantages: affordable and high plasticity. Disadvantages: Rubber bands are very elastic and not easy to fix. The joints are stretched open, but the occlusal surface will be closed, which is not easy to clean. In addition, during the high-temperature drying process of the washing machine, the rubber bands will melt to a certain extent as the temperature changes, and the melted rubber bands will stick to the fixed part of the rongeurs, requiring secondary processing. 2. Metal spreader, disadvantages: inconvenient to fix, cannot choose size, and easily get stuck in the hands of staff during fixation or removal, causing injury, expensive, and easy to lose.
