Referring to fig. 1 and 2, a plurality of outwards turned jaws 31 are circumferentially disposed around an edge of one end of the rod body 3, each jaw 31 is rotatable, an outer sleeve 32 is movably sleeved on the outer side of the rod body 3, when the outer sleeve 32 moves towards the jaws 31, the outer sleeve 32 can push each jaw 31 to retract and clamp into the clamping ring groove 12, and the outer sleeve 32 can push the push ring 2 to squeeze the two clamping plates 11 to retract continuously.
It should be noted that the fixing head 1 and the rod body 3 are made of medical plastic materials, and the clamping plate 11 and the clamping jaw 31 are respectively integrally formed with the fixing head 1 and the rod body 3, so that the clamping plate 11 and the clamping jaw 31 rotate with the fixing head 1 and the rod body 3 in a plastic deformation mode, and can return to an initial abduction state independently when no external force is applied.
When the progestin ring fixing device provided by the invention is specifically used, the rod body 3 can be matched with a hysteroscope, the rod body 3 is penetrated into the lumen of the hysteroscope and the clamping jaws 31 penetrate out of the lens of the hysteroscope, the progestin ring is fixedly connected with the push ring 2 or the fixing head 1 through wires, the fixing head 1 can be clamped between the clamping jaws 31 by using tools such as forceps, so that each clamping jaw 31 is aligned with the clamping ring groove 12 of the fixing head 1, the outer sleeve 32 moves towards the clamping jaw 31, the outer sleeve 32 pushes each clamping jaw 31 to retract and clamp into the clamping ring groove 12 so as to fix the fixing head 1 and the end part of the rod body 3, the fixing head 1 is conveyed into the uterine cavity of a patient through the hysteroscope, the fixing head 1 is pushed towards the rear wall of the uterine cavity so as to enable the inner sides of the clamping plates 11 to abut against the rear wall of the uterine cavity, then the outer sleeve 32 is continuously moved, the push ring 2 is pushed and the two clamping plates 11 are extruded inwards so as to enable the two clamping jaws 31 to push the rear wall tissues of the uterine cavity inwards, simultaneously, the needle body 111 can be hooked on the rear wall of the uterine cavity 1, the clamping jaws 31 can be separated from the outer sleeve 3, and the outer sleeve body 3 can be retracted, and the fixing of the rod body can be completed after the fixing body 1 and the outer sleeve body 3 is separated, and the body 3 is fixed, and the body can be fixed after the body separated from the body 3 from the uterine cavity 3.
The invention controls the adduction and locking of the two clamping plates 11 through the movement of the push ring 2, the needle body 111 is utilized to hook the tissue of the rear wall of the uterine cavity to be clamped between the two clamping plates 11, the tissue of the rear wall of the uterine cavity can be pushed inwards to assist clamping in the adduction process of the clamping plates 11, and the push ring 2 can limit the expansion of the clamping plates 11 after pushing the clamping plates 11 to adduction is completed, so as to complete the fixation of the fixing head 1 and the rear wall of the uterine cavity; the invention can quickly realize the fixation and separation of the fixed head 1 and the rod body 3 and the adduction control of the push ring 2 on the clamping plate 11 by only controlling the back and forth movement of the outer sleeve 32, and is convenient to operate.
In order to avoid that the push ring 2 pushes the two clamping plates 11 to retract back to the fixing head 1 after being retracted, so that the clamping plates 11 are out of constraint and abduct to cause fixing failure, in an embodiment, one sides of the two clamping plates 11 away from each other are respectively provided with a clamping block 112, the distance between the clamping blocks 112 and the distal ends of the clamping plates 11 is greater than the width of the push ring 2, and two through grooves 21 are symmetrically formed in the inner side wall of the push ring 2. When the push ring 2 is used specifically, the push ring 2 is rotated to enable the clamping block 112 to be located on the moving path passing through the groove 21, so that the push ring 2 is not blocked by the clamping block 112, and when the push ring 2 pushes the two clamping plates 11 to retract and pass through the clamping block 112, the push ring 2 is rotated to enable the clamping block 112 to be staggered with the groove 21, so that the push ring 2 can be prevented from retreating to the fixing head 1.
In order to conveniently control the push ring 2 to rotate, further, one side of the push ring 2 far away from the clamping plate 11 is provided with a plurality of slots 22, one end of the outer sleeve 32 close to the clamping jaw 31 is provided with a plurality of inserting columns 321 matched with the slots 22, and when the outer sleeve 32 pushes the push ring 2, the inserting columns 321 are inserted into the slots 22, so that the push ring 2 can be controlled to rotate in a mode of rotating the outer sleeve 32.
Preferably, the surface of the insert post 321 is covered with a soft cushion layer, so that the insert post 321 can be slightly inserted into the slot 22 with interference, and the insert post 321 is prevented from directly sliding out of the slot 22 when the outer sleeve 32 is retracted. When the progestogen ring needs to be dismantled after a period of time, the rod body 3 is sent into the uterine cavity of a patient through the hysteroscope, the outer sleeve 32 is moved to enable the claw 31 to clamp the fixed head 1, the outer sleeve 32 is pushed to enable the inserting post 321 to be inserted into the inserting slot 22, the push ring 2 is rotated to enable the clamping block 112 to be aligned through the slot 21 and pull the push ring 2 to be far away from the clamping plate 11, the clamping plate 11 is outwards unfolded after being separated from the constraint, and then the separation of the fixed head 1 and the rear wall of the uterine cavity can be realized, so that the removal of the progestogen ring is completed.
In an embodiment, the end of the fixing head 1 far away from the clamping plate 11 is provided with a conical head 14, and the end of the rod body 3 near the clamping jaw 31 is provided with a guide groove 33 adapted to the conical head 14, which is beneficial to auxiliary guiding, so that the fixing head 1 and the rod body 3 are quickly and accurately abutted.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting thereof; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features can be replaced with equivalents; such modifications and substitutions do not depart from the spirit of the invention, and are intended to be included within the scope of the claims and description.
