Description

TECHNICAL FIELD

[0001] The utility model relates to a vagina dilatation technical field, concretely relates to a vagina dilatation device. BACKGROUND

[0002] At present, when carrying out vaginal examination and operation, a vaginal dilator is needed to fully expose the vagina so as to facilitate the examination and operation of doctors. The common vaginal dilator is duck-billed dilating forceps, which is opened by pressing the handle of the dilating forceps to realize the dilation of the vagina. However, due to the difference in body structure of patients, the length of the dilating forceps is fixed, so it is difficult to adapt to the dilation of different patients. At the same time, when the dilator is put into the vagina of the patient, the depth of the dilator is difficult to determine, and only the experience of the doctor is relied on to place the dilator.

[0003] The utility model patent with patent No. CN218684638U discloses a adjustable post-vaginoplasty vaginal dilatation device, which comprises a gas bag, a guide head and an inflation part. The inflation part is installed in the interior of the gas bag. The top of the gas bag is provided with a guide head. The gas bag is provided with a telescopic part and an expansion part which are isolated from each other. The outer side wall of the expansion part is provided with a screw thread to prevent the vaginal dilatation device from falling. The telescopic part is arranged at the upper end of the expansion part. The outer side wall of the telescopic part is provided with a telescopic thread. The telescopic thread is unfolded after the telescopic part is inflated. The inflation part penetrates the telescopic part and the expansion part. Before use, the vaginal dilatation device is placed in the body. During the placement process, the soft and elastic guide head is used to guide the gas bag into the body, and the inflation part can play a supporting role. During use, the inflation part inflates the telescopic part and the expansion part of the gas bag. After the telescopic part is injected with air, the telescopic thread is unfolded, and the telescopic part is elongated to a deeper position, so that the vaginal dilatation device can completely conform to the length of the patient's vagina. After the expansion part is inflated, it can well fit the shape and size of the patient's vagina. In this patent, the telescopic part can be elongated, but the length of the telescopic part is difficult to accurately control, and it is difficult to accurately dilate the patient's vagina.

[0020] In an embodiment, referring to Figure 1 The utility model discloses a vaginal dilator, which comprises a support cover 1 pipe, a telescopic assembly and a dilatation assembly.

[0021] The support cover 1 is internally provided with an installation channel 2. The telescopic assembly comprises a telescopic cover 3 movably arranged in the installation channel 2. Both ends of the telescopic cover 3 extend beyond both ends of the support cover 1. The telescopic cover 3 is internally provided with an observation channel 4. The outer wall of the telescopic cover 3 is provided with a length scale 5. The telescopic cover 3 rotates under the action of an external force, so that the length of both ends of the telescopic cover 3 extending beyond both ends of the support cover 1 changes. The dilatation assembly comprises a dilatation cover 6 arranged outside the support cover 1, a first inflation member in communication with the dilatation cover 6, a dilatation ring 7 arranged on one end of the telescopic cover 3, and a second inflation member in communication with the dilatation ring 7. One end of the dilatation cover 6 away from the support cover 1 is connected to one end of the telescopic cover 3 close to the dilatation ring 7. The first inflation member inflates the dilatation cover 6 under the action of an external force, so that the dilatation cover 6 expands along the circumference of the support cover 1. The second inflation member inflates the dilatation ring 7 under the action of an external force, so that the dilatation ring 7 expands along the circumference of the telescopic cover 3.

[0022] Further, referring to Figure 2The inside of the support sleeve 1 is hollow to form a mounting channel 2, and the end of the support sleeve 1 away from the expansion ring 7 is provided with an adjusting sleeve 8.

[0031] In the above arrangement, the transparent expansion sleeve 6 facilitates observation of the observation scale 9 on the support ring, thereby controlling the depth of the support sleeve 1 placed in the patient's vagina, the expansion sleeve 6 is bonded between the expansion ring 7, so that there is no gap between the expansion sleeve 6 and the expansion ring 7; during the rotation of the adjusting sleeve 8, the protruding strip slides in the groove 10, thereby avoiding the rotation of the telescopic sleeve 3 in the support sleeve 1.

[0032] Further, referring to Figure 1 , the first inflation member comprises a first inflation pipe 11 arranged on the supporting sleeve 1 and communicated with the expanding sleeve 6, and a first valve 12 arranged on the first inflation pipe 11; the second inflation member comprises a second inflation pipe 13 arranged on the outer wall of the supporting sleeve 1 and communicated with the expanding ring 7, and a second valve 14 arranged on the second inflation pipe 13, and the second inflation pipe 13 is located inside the expanding sleeve 6.

[0033] Preferably, the device further comprises an inflation pump 15, and a main gas pipe 16 is arranged on the inflation pump 15, and a three-way valve 17 is arranged on the main gas pipe 16 and communicated with the first inflation pipe 11 and the second inflation pipe 13 respectively.

[0034] In the above arrangement, the inflation pump 15 is controlled by the three-way valve 17 to inflate the first inflation pipe 11 or the second inflation pipe 13 respectively, and the gas inflating or discharging in the expanding sleeve 6 and the expanding ring 7 is controlled by the first valve 12 and the second valve 14 respectively, so as to control the inflation or deflation of the expanding sleeve 6 and the expanding ring 7 respectively.

[0035] Further, referring to Figure 2 , the part of the second inflation pipe 13 located inside the expanding sleeve 6 is provided with an expansion pipe 18.

[0037] In the above arrangement, the expansion pipe 18 is elongated when the expansion pipe 18 moves away from the supporting pipe to elongate the device as a whole.

[0038] In the embodiment, the supporting sleeve 1 is placed into the vagina of a patient, and the depth of the supporting sleeve 1 placed into the vagina of the patient can be known according to the observation scale 9 on the outer wall of the supporting sleeve 1 and the length of the end of the expansion ring 7 provided on the expansion sleeve 3, and the expanding sleeve 6 (after the patient undergoes a vaginal forming plastic surgery) or the expansion ring 7 (for treating the lesion position inside the vagina of the patient) can be controlled respectively according to the need, or both the expanding sleeve 6 and the expansion ring 7 can be inflated to expand the vagina of the patient; the drug, observation instrument or surgical instrument can be put into the vagina of the patient through the observation channel 4 to operate; and the expansion sleeve 3 can be elongated by rotating the adjusting sleeve 8 to penetrate into the inside of the vagina of the patient, so as to adapt to different patients.

[0039] The above only describes the preferred embodiments of the device and should not be used to limit the device, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the device should be included in the protection scope of the device.
