a speculum

Abstract

The invention discloses a vaginal speculum, which comprises an upper blade and a lower blade. The front ends of the upper blade and the lower blade form a channel that can be opened and closed. A handle extends downwards from the opening end of the channel, and the middle part of the connecting plate runs through to form an observation window that runs through the channel. The connecting plate and the handle are connected by sliding. The blade is also provided with a driving mechanism, which is used to control the clamping mechanism to clamp and fix the cervical forceps, and is also provided with a locking mechanism for locking the connecting plate and the handle, and adjusting the size of the channel. By clamping and locking the cervical forceps, the doctor can In the process of using the speculum and cervical forceps for vaginal examination, the cervical forceps can be easily installed and disassembled, and the upper and lower blades of the speculum can be locked at an appropriate degree of opening during the doctor's examination, and the cervical forceps and the peeping forceps can be prevented. Vaginal slippage.

Description

technical field [0001] The invention relates to the field of medical instruments, and more specifically relates to a vaginal speculum. Background technique [0002] A speculum is a medical device used for vaginal voyeurism and is often used in hysteroscopy and other operations. [0003] At present, the Chinese patent application No. CN201410811833.6 discloses a multifunctional vaginal dilator, which has a first assembly part, and the speculum includes: an upper page of the speculum; and a lower page of the speculum, which is the same as The upper page of the speculum is hinged together, and the front ends of the upper page of the speculum and the lower page of the speculum have a closed state and an open state; Assembling part, the cervical clamper can pass between the upper page of the speculum and the lower page of the speculum and assemble the cervical clamper on the first assembly part through the second assembly part, and the speculum also includes a locking mechanism ...

AI Technical Summary

Problems solved by technology

Moreover, the uterus itself is an active organ, and the position of the uterus will continue to change as doctors perform operations. After the above-mentioned disclosed cervical clamp is fixed in the first assembly part, if it is necessary to adjust the clamping position of the cervix, the cervix needs to be clamped. It is very inconvenient to remove the holder and install it again

Although the above-mentioned multifunctional vaginal dilator has a locking mechanism that can keep the front ends of the upper and lower pages of the speculum in a certain open state, in the actual operation process, the upper and lower pages of the speculum The degree of opening often needs to be adjusted, and the above-mentioned speculum can only be locked in an open state, which will encounter many problems in actual operation
