Furthermore, the terms "first," "second," and the like, if any, are used merely for distinguishing between descriptions and not for indicating or implying a relative importance.

It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.

In the uterus gland myopathy uterus protecting operation process, due to lack of guidance, the uterine cavity can be opened by mistake in most cases. If there were appropriate guide instruments to help determine the position of the uterine cavity during surgery, it would be of great benefit to improve surgical accuracy. Currently, there is no medical device specifically designed in the market today for preventing surgical incision through the uterine cavity. If the balloon is used for guiding, firstly, no obvious difference exists in sense of touch; secondly, the balloon is easy to be extruded and broken, and has no practical value. If the uterus dilating rod is used for guiding, firstly, the uterine cavity cannot be filled, and secondly, the uterine cavity is easy to cause electric injury. The bead string guide, the imbedding device and the uterus protecting operation guide can solve the problems.

The bead string guide, the inserter and the uterus-protecting operation guide according to the present embodiment will be described in detail with reference to fig. 1 to 6.

Referring to fig. 1 to 4, an embodiment of the present invention provides a bead string guide, comprising: a pouch 110, the pouch 110 having a strip-shaped channel; the plurality of hard guide beads 120 are accommodated in the channel, and the plurality of hard guide beads 120 are sequentially arranged along the extending direction of the channel; the pouch 110 containing the plurality of rigid guide beads 120 is used to sequentially feed into the uterine cavity 400 to fill the uterine cavity 400 after being folded.

The hard guide beads 120 are loaded into the pouch 110, and the pouch 110 serves to block the hard guide beads 120 from human tissue, to restrain the hard guide beads 120, and to prevent the hard guide beads 120 from being pressed into human tissue. The guide beads are made of hard materials, so that the guide beads are in strong tactile contrast with uterine wall tissues with relatively soft textures in operation, and a doctor can judge the guide beads conveniently. Thus, "rigid guide beads 120" refer to guide beads that are relatively rigid with respect to uterine wall tissue, and are relatively rigid with respect to the subject of the procedure when used in other procedures.

Referring to fig. 1, the pouch 110 has a strip-shaped channel. Pouch 110 is cylindrical after being expanded, for example, 120mm in length and 50mm in diameter; the thickness of the pouch 110 is 15 filaments. The pouch 110 is made of Polyethylene (PE), which is a thermoplastic resin obtained by polymerizing ethylene. Industrially, copolymers of ethylene with small amounts of alpha-olefins are also included. Other soft materials, such as silicone, may also be used for the pouch 110. The material of the pouch 110 may be elastic, or otherwise inelastic.

Referring to fig. 2, the inner diameter of the channel of the pouch 110 approximates the diameter of the hard guide beads 120, and the plurality of hard guide beads 120 are arranged in a bar shape under the restriction of the channel after the plurality of hard guide beads 120 are loaded into the pouch 110.

Referring to fig. 3 and 4, before the operation, one end of the pouch 110 having the plurality of hard guide beads 120 is inserted into the uterine cavity 400, and continuously fed, the pouch 110 having the plurality of hard guide beads 120 is folded, and finally the uterine cavity 400 is filled, thereby completing the introduction.

In this embodiment, a pouch 110 containing a plurality of rigid guide beads 120 is placed into the uterine cavity 400 by an introducer. It should be noted that, as will be understood by those skilled in the art, the front end of the introducer is used to extend into the human body during use, and the rear end of the introducer is operated by a doctor. Thus, relatively, the portion of each component near the front end of the introducer is referred to as the distal end of the component, and the portion of the component near the rear end of the introducer is referred to as the proximal end of the component. In fig. 1, the front end of the pouch 110 near the introducer (i.e., the left end of the pouch 110 in fig. 1) is the distal end of the pouch 110, and the rear end of the pouch 110 near the introducer (i.e., the right end of the pouch 110 in fig. 1) is the proximal end of the pouch 110.

With continued reference to fig. 1, in particular, the pouch 110 has opposite distal and proximal ends, the distal end of the pouch 110 is closed, the proximal end of the pouch 110 is provided with an opening, and a plurality of rigid guide beads 120 are sequentially loaded into the pouch 110 from the opening.

In this embodiment, the distal end of the pouch 110 is provided with a reinforcement 111. The distal end of the balloon 110 first protrudes into the uterine cavity 400, which is relatively stressed, and the provision of the stiffening portion 111 at the distal end of the balloon 110 helps to prevent the balloon 110 from being pierced by the rigid guide beads 120, the introducer or other foreign objects.

Specifically, the reinforcement 111 has an oval shape, and the diameter of the reinforcement 111 is smaller than the diameter of the pouch 110. Specifically, the thickness of the reinforcing portion 111 is 0.3mm to 0.5mm. The reinforcement 111 is fixed to the distal end of the pouch 110 by hot pressing.

Referring to fig. 2, in the present embodiment, the hard guide beads 120 are spherical. The hard guide beads 120 are made of non-metal materials. In order to avoid electrical damage during surgery. Specifically, the diameter of the hard guide beads 120 is 6mm, the number of the hard guide beads 120 is 50, the volume of 10ml (the volume of the normal uterine cavity 400 is 5 ml) can be ensured to be filled, the uterine cavity 400 is increased due to the increase of the adenomyosis, the number of the hard guide beads 120 is 50, the filling is ensured, the redundancy is maintained, and the effect is ensured. The diameter and number of the hard guide beads 120 can be adjusted according to practical requirements.

Referring to fig. 2, in the present embodiment, the bead string guiding member further includes a string wire 121, the plurality of hard guiding beads 120 are connected to the string wire 121, and the plurality of hard guiding beads 120 are spaced apart along the string wire 121.

Specifically, the string 121 is made of nylon or other hard plastic. The diameter of the string 121 is 6mm. The manufacturing process comprises the following steps: 1. firstly, processing a hemisphere of a hard guide bead 120; 2. the string 121 is straightened and the hemispheres of the hard guide beads 120 are added on both sides for fixation by hot pressing or gluing.

In this embodiment, a plurality of hard guide beads 120 are spaced apart along the string 121. Therefore, the bead string guide piece can be flexibly placed, and winding can be avoided. Specifically, the length of the string 121 between the hard guide beads 120 is twice the diameter of the hard guide beads 120, for example, the diameter of the hard guide beads 120 is 6mm, the number is 50, the length of the string 121 between the hard guide beads 120 is 12mm, and the total length of the string 121 is 900mm. In other embodiments, the length of the string 121 between the hard guide beads 120 may be 6mm, 8mm, 10mm.

In this embodiment, the diameter of the channel is equal in the direction from the distal end to the proximal end of the channel; or the diameter of the channel decreases gradually in the direction from the distal end to the proximal end of the channel.

Correspondingly, the diameters of the channels are equal in the direction from the distal end to the proximal end of the channels, and the diameters of the plurality of rigid guide beads 120 are equal and are arranged in the direction in which the channels extend.

Similarly, the diameter of the channel decreases gradually in the direction from the distal end to the proximal end of the channel, approximating an inverted triangle. The plurality of rigid guide beads 120 also taper in diameter in a distal to proximal direction of the channel, similar to the diameter of the channel, distributed in rows.

Both of the above methods are performed by the implanter described below to implant the uterine cavity 400.

One end of the pouch 110 having the plurality of hard guide beads 120 is placed into the insertion tube 210 from the introduction port 230, and the pouch 110 in a strip shape extends along the extension direction of the insertion tube 210. The front half of the introducer is in the uterine cavity 400 and the rear half is in the vagina. The intravaginal space is sufficient for the pusher to push the rigid guide beads 120 enclosed in the pouch 110, and the rigid guide beads 120 protrude from the insertion opening 220 under the pushing action of the pusher to fill the uterine cavity 400.

Specifically, the insertion port 220 is open at the distal end of the insertion tube 200. The introduction port 230 extends through the wall thickness of the end wall and side wall of the proximal end of the insertion tube 200. Specifically, the introduction port 230 includes a first introduction port 230 extending along a side wall of the insertion tube 200 and a second introduction port 230 opened at a proximal end portion of the insertion tube 200.
