[0046] Embodiment 1:

[0047] See also Figure 1-Figure 13 , the present invention provides a technical solution:

[0048] An embryo transplanter for test tube babies comprises a gripping handle 100 and a positioning mechanism 300; wherein:

[0049] The surface of the gripping handle 100 is fixedly connected with a plurality of anti-skid rubber strips 200, and the plurality of anti-skid rubber strips 200 are vertically distributed on the surface of the gripping handle 100;

[0050] The positioning mechanism 300 is installed inside the gripping handle 100, and includes a control component 310 installed inside the gripping handle 100. The surface of the control component 310 extends to the top of the gripping handle 100, and one end of the control component 310 passes through the gripping handle 100 and is connected to a depth positioning component 320. The end of the depth positioning component 320 away from the control component 310 is connected to an offset positioning component 330. The positioning mechanism 300 also includes an inner tube 340, which passes through the control component 310 and the depth positioning component 320, and extends into the offset positioning component 330, and matches the offset positioning component 330.

[0051] It should be noted that, in the present embodiment, by configuring the control component 310, the depth positioning component 320 and the offset positioning component 330 of the positioning mechanism 300, a system capable of accurately positioning the inner tube 340 is formed. When in use: by cooperating with the offset positioning component 330 and the depth positioning component 321, a relatively accurate positioning effect can be formed on the end of the inner tube 340, so that during the embryo transplantation operation, the end of the inner tube 340 can be controlled to more accurately place the embryo in a specific implantation area, thereby improving the success rate of embryo transplantation; by cooperating with the control component 310 and the offset positioning component 330, the expansion size of the telescopic membrane can be controlled so that the offset amplitude of the inner tube 340 can be controlled, so that the embryo can be more accurately placed in a specific implantation area, thereby improving the success rate of embryo transplantation; and the problem that after the injection tube of the existing transplantation tube extends into the interior of the mother, it is difficult to accurately control the implantation position of the transplanted embryo, thereby affecting the success rate of embryo transplantation is solved.

[0052] The inner tube 340 is an embryo transfer tube for embryo transfer, which is made of soft rubber material and is usually kept in a hospital laboratory. Before the operation, the embryo transfer tube is used to store the culture medium containing sperm embryos and then handed over to the surgeon for operation.

[0053] External channel

[0054] Embodiment 2:

[0055] Different from Example 1, Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.10As shown, the offset positioning component 330 includes a soft rubber inserting head 331, which is fixedly mounted on the end of the depth positioning component 320 away from the control component 310, and a control groove 332 is provided at the upper end of the soft rubber inserting head 331, and a third guide channel 333 is provided at the end of the soft rubber inserting head 331 close to the depth positioning component 320, and the third guide channel 333 is connected to the control groove 332, and an air gathering groove 336 is also provided inside the soft rubber inserting head 331, and the air gathering groove 33 6 is communicated with the control groove 332, and a telescopic membrane 334 is fixedly connected to the inner wall of the gas gathering groove 336; the longitudinal cross-sectional height of the telescopic membrane 334 at one end close to the depth positioning component 320 is greater than the longitudinal cross-sectional height of the other end of the telescopic membrane 334, and a plurality of groups of rubber sheets 335 are installed on the inner wall of the control groove 332, and the rubber sheets 335 are installed on the surface of the telescopic membrane 334, and the gap between the two rubber sheets 335 at one end close to the control component 310 is smaller than the gap between the two rubber sheets 335 at the other end.

[0056] It should be noted that, in the present embodiment, through the arrangement of the above-mentioned structure, when in use, the piston 313 can be driven by driving the pen-type electric push rod 312 to move in the direction of the offset positioning assembly 330 inside the inner cavity 314. At this time, the air inside the inner cavity 314 is squeezed, and then part of the gas is injected into the interior of the second air duct 326 through the first air duct 316, and the gas is injected into the interior of the gas gathering groove 336 through the second air duct 326. At this time, due to the increase of gas inside the gas gathering groove 336, the air pressure increases, and then the telescopic membrane 334 expands, and then the expansion of the telescopic membrane 334 will cause the inner tube 340 to resist bending, and because the end of the telescopic membrane 334 away from the operation of medical personnel is thinner, the thin end of the telescopic membrane 334 expands first, and then the front end of the inner tube 340 is adjusted to bend preferentially.

[0057] In a preferred embodiment, Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, there are six rubber sheets 335, which are formed into a pair of two, and there are a total of three pairs. Each pair of rubber sheets 335 can form an embracing positioning on both sides of the inner tube 340. Each group of rubber sheets 335 is formed by a combination of three soft rubber sheets that gradually increase from the inside to the outside. The gap between the pair of rubber sheets 335 close to the depth positioning component 320 is smaller than the gap between the pair of rubber sheets 335 away from the depth positioning component 320. When the telescopic membrane 334 starts to expand from the thin end, the two rubber sheets 335 adjacent to the thin end gradually move away from each other during the expansion process, thereby gradually releasing the positioning effect on the inner tube 340, and the expansion of the telescopic membrane 334 simultaneously resists the inner tube 340 to cause displacement, so as to achieve the control of the end of the inner tube 340 to more accurately place the embryo in a specific implantation area during the embryo transplantation operation, thereby improving the probability of successful embryo transplantation.

[0058] Embodiment 3:

[0059] Different from the above embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the depth positioning component 320 includes an outer tube 321, which is fixedly connected to one end close to the control component 310, and a plurality of positioning protrusions 322 are fixedly connected to the surface of the outer tube 321; a positioning ring 323 is also sleeved on the surface of the outer tube 321, and the positioning ring 323 is located between adjacent positioning protrusions 322, and a second guide channel 325 is opened at one end of the outer tube 321, and a second air guide channel 326 opened at the end of the outer tube 321 is provided on the side of the second guide channel 325 away from the upper end of the control component 310.

[0060] The plurality of positioning protruding tubes 322 are evenly distributed in a straight line along the surface of the outer tube 321, and the positioning protruding tubes 322 are annularly sleeved on the surface of the outer tube 321. An inner ring groove 324 is formed inside the positioning protruding tube 322, and the inner ring groove 324 is communicated with the inner wall of the positioning protruding tube 322, and a marking paper tag is fixedly connected to the inner wall of the inner ring groove 324;

[0061] It should be noted that, in this embodiment, through the arrangement of the above structure, during use, the positioning convex tube 322 can be used to cooperate with the positioning ring 323, so that the positioning ring 323 can be sleeved on the outer tube 321, and the positioning convex tube 322 can be used to assist in positioning the position of the positioning ring 323. At the same time, since the positioning ring 323 itself is made of a flexible silicone material component, and the diameter of the positioning ring 323 is larger than the diameter of the insertion port of the patient's internal organ, the position of the positioning ring 323 is adjusted according to the depth of the patient's internal organ, so that the distance from the soft rubber insertion head 331 to the side of the positioning ring 323 is smaller than the depth of the patient's internal organ, so as to avoid the end of the soft rubber insertion head 331 from contacting the patient's internal organ; at the same time, the positioning ring 323 can assist in positioning the control groove 332 relative to the patient's internal organ, and then assist in placing the embryo in a specific implantation area, thereby increasing the probability of successful embryo transplantation.

[0062] Embodiment 4:

A first guide channel 317 and a first air channel 316 are opened inside the hard rubber block 315, a protective film 318 is fixedly connected to the first guide channel 317 near the inner wall of the gripping handle 100, the first air channel 316 is connected to the inner cavity 314, and a compensation hole 319 is opened at the end of the built-in block 311 near the pen-type electric push rod 312, and the compensation hole 319 is connected to the inner cavity 314.

[0064] It should be noted that, in the present embodiment, through the arrangement of the above structure, the piston 313 is driven to move in the direction of the offset positioning assembly 330 inside the inner cavity 314 by driving the pen-type electric push rod 312. At this time, the air inside the inner cavity 314 is squeezed, and then part of the gas is injected into the second gas channel 326 through the first gas channel 316, and the gas is injected into the gas collection groove 336 through the second gas channel 326. When the piston 313 moves, the gas is injected into the inner cavity 314 through the compensation hole 319, thereby ensuring the piston 313. The movement is smooth. When using the inner tube, the protective film 318 is punctured with the assistance of the inner tube or other objects. The inner tube enters the second guide channel 325 along the first guide channel 317, and then the end of the inner tube is extended to the inside of the control groove 332 and the end of the inner tube is assisted in positioning by multiple rubber sheets 335. The protective film 318 can reduce the entry of external bacteria into the patient's body. The piston 313 moves in the inner cavity 314 to control the amount of gas injected into the gas gathering groove 336, so as to assist the embryo in being placed in a specific implantation area and increase the probability of successful embryo transplantation.

[0065] The use principle of the embryo transplanter for test tube babies of the present invention is:

[0066] During use, the medical staff holds the gripping handle 100 to pass the end of the inner tube 340 through the protective film 318, through the first guide channel 317 and the second guide channel 325, and extends to the inside of the control groove 332. The end of the inner tube is positioned by a plurality of rubber sheets 335. According to the marking paper in the inner ring groove 324 on the inner side of the positioning convex tube 322, the position of the positioning ring 323 on the surface of the outer tube 321 is adjusted. The soft rubber insertion head 331 is inserted into the patient's body. The side of the positioning ring 323 fits the patient's organ port, and the pen-type electric push rod 312 is driven to drive the piston 313 to move in the inner cavity 314 toward the offset positioning component 330. At this time, the inner cavity 3 The air inside 14 is squeezed, and part of the gas enters the second air channel 326 through the first air channel 316, and the gas is injected into the gas collecting groove 336 through the second air channel 326. As the gas inside the gas collecting groove 336 increases and the air pressure increases, the telescopic membrane 334 starts to expand from the thin end, and the two rubber sheets 335 adjacent to the thin end gradually move away during the expansion process, gradually releasing the positioning effect on the inner tube 340, and the expansion of the telescopic membrane 334 simultaneously resists the inner tube to deflect, so that during the embryo transplantation operation, the end of the inner tube 340 is controlled to more accurately place the embryo in a specific implantation area, thereby increasing the probability of successful embryo transplantation.
