Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of disposable uterine biopsy sampler, concretely relates to a disposable uterine biopsy sampler with disinfecting function. BACKGROUND

[0002] Disposable uterine biopsy sampler, also known as disposable cervical biopsy forceps, is a commonly used medical instrument used to obtain biopsy samples of cervical tissue in gynecological examination. The structure of uterine biopsy forceps generally consists of a power-assisted handle and a double-claw grabbing head. The two claw-shaped parts of the grabbing head can open and close, and when closed, they can penetrate into the cervical tissue to obtain tissue samples. The handle can control the opening and closing action of the grabbing head and provide the required force. When using cervical biopsy forceps for biopsy, the doctor will first use a colposcope or other instrument to observe the cervix and determine the location of the biopsy requirement. Then, the doctor inserts the cervical biopsy forceps into the vagina until it reaches the cervix. By operating the handle, the doctor can close the grabbing head, penetrate into the cervical tissue, and gently rotate and stretch to obtain a small piece of tissue sample. After the biopsy is completed, the grabbing head will automatically open and release the tissue sample. The main advantage of cervical biopsy forceps is that it is easy to operate and can obtain high-quality biopsy samples in a short time. It is suitable for the diagnosis and evaluation of cervical lesions such as precancerous lesions of the cervix, cervical polyps, and cervicitis. Moreover, the stimulation of cervical biopsy forceps is relatively small for patients and can avoid more invasive operations such as surgical resection.

[0003] However, it should be noted that when using cervical biopsy forceps for biopsy, relevant hygiene and disinfection requirements should be followed to ensure the safety and hygiene of the operation. The uterine biopsy forceps need to be disinfected before sampling, and disinfection requires the use of disinfection equipment, which increases the cost. Currently, the cervical biopsy forceps on the market do not have disinfection function. This phenomenon has become a problem that needs to be solved by personnel in this field. UTILITY MODEL CONTENT
