Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a cleaning brush for a forceps channel hole of an endoscope. Background Art

[0002] An endoscope is an instrument commonly used in medical diagnosis and treatment. It enters the body through the body's natural cavities or small skin incisions so that doctors can observe the body's internal conditions. The forceps channel is a very critical part of the endoscope. It is a channel specially designed for inserting tools such as biopsy forceps and electrocautery forceps. Since these forceps channel holes are narrow and tortuous, conventional cleaning methods are difficult to completely remove internal contaminants. Therefore, a special cleaning brush is required to ensure the hygiene and safety of the endoscope. However, existing endoscope cleaning brushes are mostly reusable. After repeated bending and deformation, the brush head main rod is easily broken and falls into the forceps channel hole of the endoscope, which is troublesome to remove.

[0003] In order to address the above problems, a Chinese patent with an existing announcement number of CN213550299U proposes an endoscope cleaning brush with high connection strength. The device adds a cable structure connected to the brush head in the spring outer tube, so that when the brush head falls off, the brush head can be pulled out by the cable. The connection between the spring outer tube and the brush head main rod adopts a variable pitch form, which can transfer the force of the brush head main rod to the spring outer tube, thereby improving the strength.

[0004] However, although the above-mentioned high connection strength endoscope cleaning brush can pull out the fallen brush head through the pull cable, the handle of the high connection strength endoscope cleaning brush is fixed to the brush head connection structure, and the brush head cannot be replaced according to actual conditions, resulting in a problem of reduced application scope of the device. Therefore, the utility model provides an endoscope channel hole cleaning brush to meet the demand. Utility Model Content
