Problems solved by technology

[0007] It can be seen that the existing vaginal dilators can only suck smoke, but cannot suck blood due to the limitation of position and suction, so it can only partially improve the surgical field of view, and the blood leaking from the surgical target tissue will still hinder the operation operation

Embodiment approach 1

[0042] The first embodiment of the present invention provides a vaginal dilator, see figure 2 As shown, it includes two expansion wings that cooperate with each other, namely an upper expansion wing 1 and a lower expansion wing 2, which can extend into the vagina and are used to open the vagina;

[0043] Wherein, the vaginal dilator further includes a diversion channel 4 for sucking out blood. The head end of the diversion channel 4 is provided with a diversion hole 6 which is located near the front half of the lower expansion wing 2.

[0044] In this embodiment, an observation window 3 is formed where the two expansion wings are connected;

[0045] The diversion channel 4 is a catheter, which extends from the observation window 3 into the vaginal dilator and is fixed above the lower expansion wing 2. When the catheter is connected to the external negative pressure suction device, the catheter set above the lower expansion wing 2 can be used to suck blood exuded from the target tiss...

Embodiment approach 2

[0049] The second embodiment of the present invention provides a vaginal dilator. The second embodiment is a further improvement of the first embodiment. The main improvement lies in that in the second embodiment of the present invention, see image 3 As shown, the lower expansion wing 2 is provided with a support frame 5, and the support frame 5 is provided with support holes; the catheter is detachably fixed on the support frame 5 through the support holes. The support hole can make the catheter detachable, so the use is more flexible.

[0050] Among them, the support frame 5 can be screwed to the catheter, so as to obtain a better fixing effect.

Embodiment approach 3

[0052] The third embodiment of the present invention provides a vaginal dilator. The third embodiment is different from the first and second embodiments. The main difference is that in the first and second embodiments of the present invention, the diversion channel 4 is a duct; while in the third embodiment of the present invention Way, see Figure 4 As shown, the diversion channel 4 is a cavity laid in the lower expansion wing 2.

[0053] Specifically, when the diversion channel 4 is a cavity laid in the lower expansion wing 2, the diversion hole 6 is opened on the lower expansion wing 2. Make the diversion channel 4 form a cavity inside the lower expansion wing 2, and the diversion channel 4 will not need to occupy the operation space between the upper expansion wing 1 and the lower expansion wing 2, and it will be less obstructive to the operation, so it can further provide more Good surgical vision.

[0054] For the position setting of the diversion hole 6, in this embodiment...

Abstract

The invention relates to the technical field of medical apparatus and instruments, and discloses a vaginal dilator. The vaginal dilator comprises two mutually matched expansion wings which are the upper expansion wing and the lower expansion wing, and the two expansion wings can extend into the vagina and are used for opening the vagina; the vaginal dilator further comprises a diversion channel used for sucking out blood, and the head end of the diversion channel is provided with a diversion hole which is located in the position close to the first half part of the lower expansion wing. The vaginal dilator can provide a better operation field.

Description

Technical field [0001] The present invention relates to the field of medical devices, in particular to a vaginal dilator. Background technique [0002] Vaginal dilator (vaginal dilator), also known as a vaginal dilator, is mainly used for routine examination and surgical treatment of gynecology. [0003] See at figure 1 In the prior art, a commonly used vaginal dilator includes a pair of cooperating expansion wings, including an upper expansion wing 1 and a lower expansion wing 2, which can be extended into the vagina and used to expand the vagina. [0004] Generally speaking, the head ends of this pair of expansion wings are duckbill-shaped, and the positioning device on the vaginal dilator is kept open at a certain angle. The doctor can use the expansion wings through the observation port 3 located in the matching part of the expansion wings. The opened field of view is inspected and operated on. [0005] When it comes to the surgical operation inside the vagina, because the electr...
