Description

Technical Field

[0001] The invention relates to the technical field of sika deer embryo transplantation, in particular to a sika deer embryo transplantation catheter device. Background Art

[0002] Embryo transplantation, also known as fertilized egg transplantation, 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. When performing embryo transplantation on sika deer, a catheter device is required. It is a key tool for embryo transplantation in sika deer or other deer species. Embryo transplantation requires the use of a sedative injection for the sika deer, and the positioning of the uterine horn through rectal ultrasound or palpation. The catheter is then gently inserted into the target uterine horn through the vagina and cervix, and the syringe is slowly pushed to allow the embryo suspension to deposit in the ideal position. Finally, the catheter residue is checked to confirm that the embryo has been successfully transplanted.

[0003] Based on the above, the inventors have found that the existing system has the following main deficiencies. For example, when performing embryo transplantation on sika deer, an external tube needs to be inserted into the uterus. However, the external tube is supported by the vagina and cervix and is relatively unstable, and is prone to falling off or shifting in position. In addition, the embryo is stored in a catheter and transplanted into the uterus of the sika deer via a syringe. However, when the syringe is pressed, the catheter connected to the catheter is prone to shaking, causing the position of the catheter port inside the uterus to shift, thereby affecting the success rate of embryo transplantation in sika deer. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that when performing embryo transplantation on a sika deer, an external tube needs to be inserted into the uterus. The external tube is supported by the vagina and cervix and is relatively unstable, and is easily dislodged or shifted in position. In addition, the embryo is stored in a catheter and transplanted into the uterus of the sika deer via a syringe. When the syringe is pressed, the catheter connected to the catheter is easily shaken, causing the position of the catheter port inside the uterus to be displaced, thereby affecting the success rate of the sika deer embryo transplantation. Therefore, a sika deer embryo transplantation catheter device is proposed.

[0005] In view of the above problems, the present invention provides a sika deer embryo transplantation catheter device.

[0006] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solution: a sika deer embryo transplant catheter device, whose structure includes a guide device, an injection device, and a catheter, the injection device is connected to the catheter, the catheter runs through the interior of the guide device, the guide device includes an outer shell, the front end of the outer shell is provided with an outer tube, and the end face of the outer tube is embedded with a fixing structure.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] Example 1: Please refer to Figures 1-4 , the specific embodiments of the present invention are as follows: Its structure includes a guide device 1, an injection device 2, and a catheter 3. The injection device 2 is connected to the catheter 3, and the catheter 3 runs through the interior of the guide device 1. The guide device 1 includes a shell 11, and the front end of the shell 11 is provided with an outer tube 13. The end face of the outer tube 13 is embedded with a fixing structure 12. The catheter 3 is supported by the injection device 2 and driven into the uterus of the sika deer by the outer tube 13. The catheter 3 is then pressurized by the injection device 2 to transplant the embryo located in the catheter 3 into the uterus of the sika deer.

[0025] A guide wheel 111 is provided at the top inner end of the shell 11, a transmission wheel 112 is provided at the bottom end of the guide wheel 111, a guide bucket 117 is provided at the left side of the top of the shell 11, a servo motor 113 is provided at the bottom inner end of the shell 11, the servo motor 113 is meshed with a transmission gear 114, the transmission gear 114 and the transmission wheel 112 are connected by a belt 115, a battery 116 is also provided at the bottom of the shell 11, and a switch structure 118 is also installed on the right side of the shell 11, the switch structure 118 is electrically connected to the servo motor 113, and the servo motor 113 is controlled by the switch structure 118 to work, so that the transmission gear 114 can drive the transmission wheel 112 to rotate through the belt 115, and the interaction force between the transmission wheel 112 and the guide wheel 111 drives the catheter 3 to move forward, so that the catheter 3 can automatically move into the uterus of the sika deer.

[0026] The fixing structure 12 includes an outer end face nested in the outer tube 13, a rubber ring 122 is provided on the inner side of the fixing ring 121, and four friction bumps 123 are provided on the bottom end face of the fixing ring 121. The friction bumps 123 are made of rubber. By moving the position of the fixing ring 121 on the end face of the outer tube 13, the depth to which the outer tube 13 extends into the uterus of the sika deer is fixed.

[0027] The friction protrusion 123 includes a fixing seat 1231 threadedly fixed to the bottom of the fixing ring 121. The friction protrusion 123 is semicircular in shape, and the end face of the friction protrusion 123 is wavy in shape. At the same time, a groove 1232 is provided at the bottom of the friction protrusion 123. After being pressed, the friction protrusion 123 can be deformed to both sides through the groove 1232, thereby increasing the friction between the friction protrusion 123 and the skin of the sika deer.

[0028] The switch structure 118 includes a button 1182 and a switch contact 1185. The button 1182 is installed inside the shell 11 through a rotating shaft 1181, and the end of the button 1182 away from the rotating shaft 1181 is connected to the inside of the shell 11 through a spring 1184. The end face of the button 1182 is also provided with a trigger patch 1183. The switch contact 1185 is installed on the inner end face of the shell 11, and the trigger patch 1183 and the switch contact 1185 are movably matched. By pressing the button 1182, the rotating shaft 1181 rotates, so that the trigger patch 1183 and the switch contact 1185 are connected and disconnected, which can control the start and stop of the servo motor 113.

[0029] Based on the above embodiment, the specific working principle is as follows: when performing embryo transplantation on a sika deer, the catheter 3 can be supported by the injection device 2, and the catheter 3 can be driven into the uterus of the sika deer through the outer tube 13. Then, the catheter 3 is pressurized by the injection device 2 to transplant the embryo in the catheter 3 into the uterus of the sika deer. When the catheter 3 is inserted into the uterus of the sika deer, it will shake. The switch structure 118 can be used to control the servo motor 113 to work, so that the transmission gear 114 can drive the transmission wheel 112 to rotate through the belt 115. The interaction between the transmission wheel 112 and the guide wheel 111 drives the catheter 3 to move forward, so that the catheter 3 can automatically move into the uterus of the sika deer, steadily pushing the catheter 3 to move, reducing the shaking of the outer tube 13, and preventing the position of the embryo implanted in the uterus from deviating. When the outer tube 13 is prone to shaking, the rubber ring 122 on the inner side of the fixing ring 121 can be used to rub against the end surface of the outer tube 13, thereby fixing the position of the movable fixing ring 121 on the end surface of the outer tube 13 and the depth of the outer tube 13 inserted into the uterus of the sika deer. At the same time, the outer tube 13 can be fixed to prevent shaking. After being pressed, the friction protrusion 123 can be deformed to both sides through the groove 1232, thereby increasing the friction between the outer tube 13 and the skin of the sika deer and preventing displacement of the outer tube 11. By pressing the button 1182, the shaft 1181 rotates, so that the trigger patch 1183 is connected to the switch contact 1185 to control the servo motor 113 to work. Then, by releasing the button 1182, the spring 1184 can drive the button 1182 to reset, and the servo motor 113 stops working.

[0030] Example 2: Please refer to Figure 5-Figure 6 , the specific embodiments of the present invention are as follows: The injection device 2 includes an injection tube 21, a threaded connection port 22 is provided on the right side of the interior of the injection tube 21, and the threaded connection port 22 is threadedly connected to the catheter 3. A rubber limit block 24 is provided on the left side of the interior of the injection tube 21. A piston structure 23 is also provided inside the injection tube 21. The piston structure 23 is movably cooperated with a return spring 25. By pressing the piston structure 23 to disconnect from the rubber limit block 24, the return spring 25 drives the piston structure 23 to move forward.

[0031] The piston structure 23 includes a piston 231, the middle position of the left side of the piston 231 is connected to the connecting rod 232, the left end face of the connecting rod 232 is connected to the pressing seat 234, the end face of the pressing seat 234 is provided with an anti-slip seat 235, and limiting blocks 233 are provided on both sides of the connecting rod 232. There is a certain friction between the rubber edging of the piston 231 and the inner wall of the injection tube 21, so that the reset spring 25 can achieve a slow sliding effect when it presses against the piston 231.

[0032] The rubber limit block 24 has a circular depression inside, and the rubber limit block 24 is movably engaged with the limit block 233 through the inner depression. The position of the piston 231 in the injection tube 21 can be fixed by the rubber limit block 24 and the limit block 233 through the inner depression.

[0033] Based on the above embodiment, the specific working principle is as follows: when pressing the syringe causes the catheter 3 to vibrate, the piston structure 23 can be pressed to disconnect from the rubber limit block 24, so that the return spring 25 drives the piston structure 23 to move forward, pushing the air inside the injection tube 21 into the catheter 3, so that the embryo inside the catheter 3 can be automatically transplanted into the uterus, and then the rubber edging of the piston 231 and the inner wall of the injection tube 21 have a certain friction, so that the return spring 25 can achieve a slow sliding effect when it presses against the piston 231, and finally the rubber limit block 24 is used to cooperate with the limit block 233 through the inner recess to fix the position of the piston 231 in the injection tube 21. When the limit block 233 in the piston 231 is disengaged from the rubber limit block 24, the return spring 25 can push the piston 231 to move.
