Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0030] Combined with Figures 1-3 , a sheep embryo transfer abdominal wall puncture sheath includes an outer sleeve rod 1 and a nut 2 provided at one end of the outer sleeve rod 1. A threaded groove is provided at one end of the outer sleeve rod 1, and a threaded block is provided inside the nut 2, and the threaded groove matches the threaded block. A sharp puncture head 11 is provided inside the outer sleeve rod 1, and a blocking cover 111 is provided at one end of the sharp puncture head 11, and a metal rod 12 is provided inside the sharp puncture head 11. An insertion interface 13 is provided on one side of the outer sleeve rod 1, and a limiting block and a sliding rod 131 are fixedly connected inside the insertion interface 13. A limiting groove is provided on the sliding rod 131, and the limiting groove matches the limiting block. A rubber pad 21 is fixedly connected to the inner side of the nut 2.

[0031] The following will further describe the present utility model in conjunction with the embodiments. Embodiment

[0032] To solve the problem that most of the existing puncture sheaths lack protective equipment, and during the puncture of sheep, it is easy to cause the needle to damage the internal organs in the sheep's body, and then it is easy to cause the sheep to be frightened, which is not convenient for operation. The following technical solutions are disclosed in this embodiment, specifically as Figures 1-3As shown in the figure, threaded grooves and threaded blocks are also provided at one end of the sharp puncture head 11 and the inner side of the blocking cover 111. One end of the metal rod 12 is fixedly connected to a first spring 121, and the first spring 121 is matched with the blocking cover 111. The other end of the metal rod 12 is fixedly connected to an anti-puncture blunt head 122. When puncture work needs to be carried out, the metal rod 12 can be placed inside the sharp puncture head 11 at this time, so that the anti-puncture blunt head 122 at one end of the metal rod 12 protrudes from the inside of the sharp puncture head 11. At this time, the blocking cover 111 can be screwed onto the sharp puncture head 11. At this time, the sharp puncture head 11 is assembled, and then the sharp puncture head 11 is placed inside the outer sleeve rod 1, and the nut 2 is screwed onto the outer sleeve rod 1. At this time, one end of the outer sleeve rod 1 can be inserted into the body of the sheep. When puncturing, due to the effect of the sheep's skin, the anti-puncture blunt head 122 at one end of the metal rod 12 is inside the sharp puncture head 11. When puncturing into the sheep's body, the anti-puncture blunt head 122 loses its acting force at this time, and then pops out from the inside of the sharp puncture head 11 under the action of the first spring 121. At this time, the anti-puncture blunt head 122 can be in contact with the internal organs of the sheep, which can avoid the situation of internal organ injury in the sheep's body and facilitate subsequent operations. Embodiment

[0033] To solve the problem that the existing puncture sheaths are often of a single structure, and during the working process, due to the small internal space of the sheep's abdomen, it is not conducive to the staff to operate quickly, which greatly affects the work efficiency. The following technical solutions are disclosed in this embodiment, specifically as Figure 1 、 Figure 4 and Figure 5As shown in the figure, a middle hole 132 is penetrated through the sliding rod 131. One side of the middle hole 132 is fixedly connected with a second spring 133, and the other end of the second spring 133 is fixedly connected with a pulling block 134. The middle hole 132 matches the inner tube of the outer sleeve rod 1. The bottom of the outer sleeve rod 1 is fixedly connected with a control box 14, and the other end of the control box 14 is fixedly connected with an anti-disconnection joint 141. A sliding block 15 is arranged inside the control box 14. A through hole 151 is formed on the sliding block 15, and the through hole 151 matches the anti-disconnection joint 141. One side of the sliding block 15 is rotatably connected with a first knob 152. One end of the first knob 152 is fixedly connected with a screw rod 153. A connecting block 154 is arranged on the outer side of the screw rod 153, and a thread matching the screw rod 153 is formed on the connecting block 154. At this time, the sliding rod 131 can be placed inside the insertion port 13, so that the limiting groove on the sliding rod 131 is engaged with the limiting block inside the insertion port 13. Then, the pulling block 134 is pressed, so that the middle hole 132 on the sliding rod 131 is sealed with the inside of the outer sleeve rod 1. At this time, the output end of an external carbon dioxide gas cylinder can be fixed with the anti-disconnection joint 141. Then, the sliding block 15 is installed on the control box 14, and the connecting block 154 is connected, so that the connecting block 154 is fixed with the screw rod 153 on the sliding block 15. At this time, carbon dioxide can enter the abdominal cavity of the sheep through the gas cylinder, the anti-disconnection joint 141 and the outer sleeve rod 1, so that the abdominal cavity expands, which is convenient for the staff to operate. When the air intake needs to be adjusted, at this time, the connecting block 154 can be held and the first knob 152 on one side of the sliding block 15 can be rotated, so that the sliding block 15 moves inside the control box 14. At this time, the opening degree of the through hole 151 on the sliding block 15 and the anti-disconnection joint 141 is changed, and then the air intake can be adjusted, realizing the function of injecting carbon dioxide gas into the abdominal cavity to make the abdominal cavity bulge, which is convenient for surgical operation.
