The body 2 comprises blades 21 with an arc-shaped cross section. Two blade caps 1 are rotatably connected to the distal ends of the blades 21. The traction piece is connected to the blade caps 1, and is suitable for driving the two blade caps 1 to rotate in a direction away from each other, or suitable for driving the two blade caps 1 to rotate in a direction close to each other. Specifically, the blade 21 has a certain extension length, so that the blade cap 1 can be pushed into a designated position of the vagina, the bottom of the blade 21 is an arc surface so as to adapt to the shape of the vagina, and discomfort caused by the insertion is reduced. The above distal end refers to the end farther from the operator, and as such, the proximal end refers to the end closer to the operator, and the distal and proximal ends are defined only for purposes of clarity of illustration of the present vaginal dilator, and are not intended to be limiting in terms of construction or manner of use.

In fig. 1, one of the blade caps 1 is shown, the blade cap 1 is rotatably arranged at the distal end of the blade 21, and the blade cap 1 can be turned over towards the outer side of the blade 21 under the driving of the traction member, thereby playing a role in expansion. The other blade cap 1 is arranged in the same way, and the traction piece can drive the two blade caps 1 to rotate in the direction away from each other so as to play a role in expansion.

When the vaginal muscle stretching device is used, the two blade caps 1 can be rotated in the directions close to each other through the traction piece, the distal ends of the blades 21 are gradually stretched into the vagina, and the two blade caps 1 can be driven to rotate in the directions far away from each other through the traction rope after stretching into place, so that vaginal muscle positioned on the outer side of the blade caps 1 is expanded and supported. Therefore, the supporting position can be accurately controlled, the supporting range can be further enlarged due to the outward rotation of the blade cap, the shielding of the sight is reduced, the damage of the instrument to the nerve-sensitive vagina part can be reduced, and the uncomfortable feeling of a patient is reduced.

Referring to fig. 2 and 3, in one embodiment of the present utility model, two shaft seats 26 are provided at the distal ends of the blades 21, and connection shafts 12 are provided on the two blade caps 1, respectively, and the two connection shafts 12 are rotatably connected to the corresponding shaft seats 26, respectively. The shaft seat 26 is arranged at the end part of the blade 21, the blade cap 1 is connected to the shaft seat 26 through the connecting shaft 12, and the blade cap 1 can rotate relative to the blade 21.

Referring to fig. 2 and 3, in one embodiment of the present utility model, the outer wall of the blade caps 1 is arc-shaped, and the opposite end surfaces of the two blade caps 1 are plane. The outer edge 11 of the blade cap 1 is arc-shaped, so that the blade cap 1 can be conveniently pushed in the vagina, and the opposite end surfaces of the two blade caps 1 are in contact with each other and then are free from gaps, so that vaginal muscles can be prevented from entering between the two blade caps 1, and the pushing of the blade caps 1 and the blades 21 is prevented.

Referring to fig. 2 and 3, in one embodiment of the utility model, the inner wall of the blade cap 1 is provided with a limit projection 13, the limit projection 13 being adapted to abut the distal end of the blade 21. The limiting protrusion 13 can limit the deflection angle of the blade cap 1 towards the blade 21, and can prevent the blade cap 1 from deflecting too much towards the blade 21, so that the subsequent expansion operation is affected.

Referring to fig. 2 and 3, in one embodiment of the present utility model, the traction member is a traction rope, one end of which is connected to the blade cap 1, and the other end of which extends from the distal end to the proximal end of the blade 21 and partially extends out of the proximal end of the blade 21, and the extending out of the proximal end of the blade 21 facilitates operation. For example, one traction rope is connected to the outer side of the blade cap 1, the blade 21 can be driven to deflect away from the blade 21 by pulling the traction rope, and the same traction rope is arranged on the other blade cap 1, so that the rotation of the two blade caps 1 is controlled. Alternatively, the traction rope can be replaced by a flexible rod, and the traction work can be completed.

In the same way, a traction rope can be connected to the inner side of the blade cap 1, for example, a traction hole 14 can be formed in the inner side of the blade cap 1, one end of the traction rope is fixed to the traction hole, the other end of the traction rope also extends to the far end of the extending blade 21, the blade cap 1 can be deflected towards the direction approaching the blade 21 by pulling the traction rope on the inner side of the blade cap 1, and the other blade cap 1 adopts the same connection mode, so that the two blade caps 1 are driven to approach each other. In addition, can also set up the elastic component between blade cap 1 and blade 21, the elastic component can be extension spring or shell fragment, when keeping away from the direction rotation of blade cap 1 to blade 21, extension spring or shell fragment can obtain elastic potential energy, later release after exerting pressure to the haulage rope, extension spring or shell fragment can drive blade cap 1 and restore to the throne.

Referring to fig. 4, in one embodiment of the utility model, the distal end of the blade 21 is provided with a through hole 25, one end of the hauling cable is attached to the outer wall of the blade cap 1, and the other end passes through the through hole 25 and extends to partially protrude out of the proximal end of the blade. For example, the through hole 25 penetrates through the wall surface of the distal end of the blade 21, so that most of the traction rope can be contained in the blade 21, and damage caused by friction between the traction rope and the inner wall of the vagina when the traction rope is pulled is avoided.

In one embodiment of the utility model, the connection of the blade cap 1 and the distal end of the blade 21 is provided with an elastic membrane. The elastic membrane can wrap the joint of the distal ends of the blade cap 1 and the blade 21, so that vagina muscles are prevented from being clamped at the joint of the blade cap 1 and the blade 21 when the blade cap 1 rotates relative to the blade 21, damage to the vagina is avoided, and the elastic membrane can be made of latex materials and has elasticity.

Referring to fig. 4, in one embodiment of the present utility model, the body 2 includes a handle 23, and the handle 23 is disposed at the proximal end of the blade 21. The handle 23 can facilitate the pushing in and pulling out actions by the operator.

Referring to fig. 4, in one embodiment of the present utility model, a plurality of protrusions 24 are provided at intervals on the handle 23, and the portion of the traction rope extending out of the blade 21 is adapted to be selectively fixed to the corresponding protrusions 24. For example, the plurality of protrusions 24 are spaced apart along the extension direction of the handle, so that the traction rope can be fixed on different protrusions 24 to control the length of the traction rope on the blade 21, and thus the offset angle of the blade cap 1 relative to the blade 21.

Referring to fig. 4, the proximal end of the blade 21 has a variable diameter section 22 of progressively larger size. The reducing section 22 allows for flexible expansion of the proximal end of the vagina for convenient manipulation by the operator.

Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the invention.
