Description

Technical Field

[0001] The invention relates to the field of medical embryo transplantation, in particular to a novel embryo transplantation tube. Background Art

[0002] Embryo transfer, also known as fertilized egg transfer, refers to the technology of transplanting early embryos in female animals, or embryos obtained through in vitro fertilization and other methods, into other female animals of the same species and with the same physiological conditions, so that they continue to develop into new individuals. The more commonly used ones are embryo transfer tubes, which are usually made of medical plastic materials, such as the embryo transfer tube with patent number CN112617987B, which is a technology that reduces the movement of the inner tube by setting a structure that can seal the inner and outer tubes.

[0003] However, the prior art usually only fixes the inner tube, and because the outer tube is mainly in contact with the patient, the outer tube may be displaced under the tense peristalsis of the muscles or hand operation. In particular, when medical plastic materials are used, once dangerous uterine contractions or muscle tension occur, the outer tube and muscles may be damaged. If the outer tube is improperly fixed to the outside, such as when clamped by the surface of other metal objects, intrauterine bleeding may occur in severe cases. Therefore, the prior art rarely uses technologies such as fixing the outer tube. Summary of the invention

A rotating groove is provided on the sleeve on the inner side of the raised buckle, and a buckle block is provided on the end of the rotating groove away from the airbag.

[0007] As a preferred technical solution of the present invention, one end of the raised block is fixedly connected to the sleeve, and the other end of the raised block contacts the inner wall of the raised buckle. The raised block is located on the middle side of the embedded strip and contacts the surface of the airbag. The airbag is arranged in an arc-shaped structure, and the airbag is provided with an opening at the sealing buckle, and the airbag is provided with an air inlet at the opening. The sealing buckle and the air inlet are threadedly connected, and the sealing buckle and the airbag surface are in embedded contact.

[0008] As a preferred technical solution of the present invention, an ovoid capsule is arranged at the upper end of the outer tube, the ovoid capsules are arranged at equal distances, and the number of the ovoid capsules is at least three.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example 1

[0025] like Figure 1-3 As shown, the present invention provides a novel embryo transfer tube, comprising a holding handle 1, a conical joint 101 is arranged at the top of the holding handle 1, an outer tube 103 is installed at the top of the conical joint 101, an inner tube 104 is arranged on the inner side of the outer tube 103, the inner tube 104 penetrates the conical joint 101 and the holding handle 1 to the bottom end, an insertion rod head 105 is installed at the bottom end of the inner tube 104, a sleeve 2 is installed at the inner wall of the outer tube 103, the sleeve 2 penetrates the conical joint 101 and the holding handle 1 to the bottom end, a rotating handle 201 is also installed at the bottom end of the sleeve 2, a rotating handle 201 is installed at the bottom end of the sleeve 2, a sliding block 202 is arranged at the top of the sleeve 2, a sliding groove 203 is arranged at the inner wall of the outer tube 103, and the sliding block 202 The outer tube 103 is embedded with the sliding groove 203, and the sliding block 202 and the sliding groove 203 are slidably connected. The surface of the outer tube 103 is provided with a raised buckle 3, and the surface of the raised buckle 3 is provided with a sealing buckle 301. An airbag 302 is installed on the inner side of the sealing buckle 301. The airbag 302 is located on the inner wall of the raised buckle 3 and is arranged at an arc angle. An embedded strip 303 is arranged on the inner side of the top and bottom ends of the airbag 302. An embedded ring 304 is installed on the top and bottom ends of the airbag 302. A raised block 305 is arranged on the inner side of the airbag 302. The raised block 305 penetrates the outer tube 103 and is connected to the sleeve 2. The sleeve 2 is provided with a rotating groove 306 on the inner side of the raised buckle 3, and a buckle block 307 is arranged on the end of the rotating groove 306 away from the airbag 302.

[0026] Furthermore, one end of the protruding block 305 is fixedly connected to the sleeve 2, and the other end of the protruding block 305 contacts the inner wall of the protruding buckle 3. The protruding block 305 is located on the middle side of the embedded strip 303 and contacts the surface of the airbag 302. The airbag 302 is arranged in an arc-shaped structure, and the airbag 302 is provided with an opening at the sealing buckle 301. The airbag 302 is provided with an air inlet 308 at the opening. The sealing buckle 301 and the air inlet 308 are threadedly connected, and the sealing buckle 301 and the surface of the airbag 302 are arranged in an embedded contact.

[0027] The rotating handle 201 and the holding handle 1 are embedded in each other, and the rotating handle 201 and the sleeve 2 are fixedly snap-fitted in each other.

[0028] The protruding block 305 and the rotating groove 306 are slidably connected, and the buckle block 307 and the protruding block 305 are arranged in a ball-bump buckle type.

[0029] Specifically, the overall structure is based on a toothed holding handle 1, a conical joint 101, an outer tube 104 and an inner tube 103. When in use, the inner tube 104 is inserted into the inner side of the outer tube 103 by inserting the rod head 102 to push the embryo into the uterus for implantation, thereby forming an embryo transplantation effect.

[0030] On top of this, since the outer tube 103 needs to remain stable when pushing, a raised buckle 3 structure is designed. When the raised buckle 3 is fixed, the rotating handle 201 at the bottom is rotated to drive the sleeve 2 at the inner wall of the outer tube 104 to rotate through the limit position at the bottom, and the sliding block 202 at the top is limited and rotated at the sliding groove 203 on the inner wall of the outer tube 104, forming a two-end rotation operation effect, thereby driving the raised block 305 located inside the middle raised buckle 3 area to be disassembled from the fixed formation at the sliding groove 203 of the outer tube 102 and the buckle block 307, and then continuously rotating until it is as shown in the figure. Figure 3 Nearby, the buckle block 307 on the surface of the sliding groove 203 is fixed by the bead buckle from the bottom of the protruding block 305;

[0031] When rotating, the raised block 305 continuously moves between the upper and lower embedded circles 304 on the inner wall of the raised buckle 3, and is limited by the embedded strip 303 connected to the embedded circle 304. At the same time, the embedded strip 303 also fixes the airbag 302 to form an arc-shaped structure frame. When the raised block 305 moves and rotates in the groove of the upper and lower embedded circles 304, it fits the inner wall of the raised buckle 3, and continuously concentrates the relatively loose airbag 302 along the arc structure to the sealing buckle 301 of the raised buckle 3, so that the airbag 302 forms a bulge at the opening, thereby completing the buckle fixing effect at the vagina outside the patient's uterus; when necessary, when the more common outer tube 103 is used, it can directly form a rotating buckle effect with the buckle parts at the edge of the bed, such as to form an extrusion fixation of the airbag 302, thereby stabilizing the pushing effect of the outer tube 103 when in use.

[0032] If the stability is not high enough, the sealing buckle 301 can be removed and air can be added to the inside of the airbag 302 from the one-way air valve at the air inlet 308 to increase the gas stored inside the airbag 302, thereby increasing the bulge effect at the opening of the airbag 302.

[0033] The overall fixing method is simple. The raised buckle 3 and the sealing buckle 301 are both arc-shaped structures, which can also reduce the impact when in contact with the patient. Since the airbag 302 structure is mainly adopted, it also uses the ball buckle to form a fixing effect. When the patient feels uncomfortable, after clamping, the airbag 302 can also produce a rebound effect to avoid damage to the patient.

[0034] Example 2

[0035] The difference from Example 1 is that Figure 4-5As shown, the utricle 4 includes an outer capsule 401 and an inner capsule 402 , a liquid cavity 403 is arranged between the outer capsule 401 and the inner capsule 402 , and the liquid cavity 403 is filled with liquid. An air cavity 404 is arranged inside the inner capsule 402 , and the air cavity 404 is filled with carbon dioxide.

[0036] The liquid in the liquid cavity 403 is filled with one of medical ethanol or lubricating liquid. The outer bag 401 is provided with a thin opening 405 near the surface of the outer tube 103 , and a film 406 is provided inside the thin opening 405 .

[0037] The liquid in the liquid cavity 403 is filled with one of medical ethanol or lubricating liquid. The outer bag 401 is provided with a thin opening 405 near the surface of the outer tube 103 , and a film 406 is provided inside the thin opening 405 .

[0038] Since a plurality of ovoid sac 4 structures are arranged at the head of the outer tube 103, the corresponding ovoid sac 4 structures can be directly viewed during ultrasound observation, which is convenient for doctors to identify and locate the effect. At the same time, since the upper tortuous area of ​​the outer tube 103 is the implantation part, if the cervical opening is too tense and tightened, a large pressure will be applied to the outer tube 103, which may cause the ovoid 4 to burst in severe cases. Therefore, an outer sac 401 and an inner sac 402 structure are arranged at the ovoid sac 4, wherein the carbon dioxide filled in the inner sac 402 will expand slightly after being exposed to body temperature for heat exchange, which can be seen more clearly under ultrasound.

[0039] Liquid, which may be medical ethanol or lubricating fluid, is arranged between the outer capsule 401 and the inner capsule 402. Therefore, when the outer capsule 4 is squeezed by a strong external force and ruptured due to the material of the oval capsule 4 itself, the outer capsule 401 ruptures first, and the liquid inside the outer capsule 401 mainly breaks through the thin opening 405, such as the film 406 made of polylactic acid, and then ruptures from the relatively brittle thin opening 405. The outflowing liquid can not only lubricate and reduce the friction caused by clamping at the cervical opening, but also form a disinfecting effect in the clamping area. The thin opening 405 can extend from the inside of the outer tube 103 to the outside, that is, the oval capsule 4 is arranged on the wall of the outer tube 103, so as to increase the recognition during ultrasonic surgery and reduce the impact on patients in case of accidents, and form a more positive lubrication effect, so that the overall tubular structure can be taken out in time.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
