Because the mounting part 400 is in clearance fit with the first hole section 111 and the electrode 300 is in clearance fit with the second hole section 121, one of the first sealing part 130 and the second sealing part 140 can be operated to slide along the first direction, so that the mounting part 400 is driven to move, and finally the electrode 300 is driven to move, so that the distance between the two electrodes 300 is adjusted to stimulate different positions of animal nerves.
It should be noted that, during the sliding process of the first sealing member 130 and the second sealing member 140 along the first direction, the first sealing member 130 always keeps the state of blocking the first hole section 111, and the second sealing member 140 keeps the state of blocking the second hole section 121, so as to avoid the contact between the part of the non-conductive end 320 on the electrode 300 and the peripheral tissue of the nerve to be stimulated during the electrical stimulation process, and not to cause the electrical stimulation to the peripheral tissue, thereby ensuring that the position of the electrical stimulation is more accurate. In other words, when the electrical stimulation apparatus 001 provided by the present embodiment is implanted in an animal to stimulate nerves of the animal, the entire apparatus except the conductive terminal 320 is insulated from the animal tissue, so as to ensure the accuracy of the electrical stimulation location.
Referring to fig. 9, in the present embodiment, optionally, the groove width of at least a part of the groove section of the positioning groove 210 on the positioning member 200 gradually increases along a direction from the notch of the positioning groove 210 to the groove bottom of the positioning groove 210, in other words, at least a part of the groove section on the positioning member 200 has a throat, after the nerve with stimulation crosses the throat and enters the positioning groove 210 near the groove bottom of the positioning groove 210, the nerve is not easy to escape from the positioning groove 210 from the throat, and the nerve is not easy to shift, so as to facilitate subsequent electrical stimulation.
Optionally, the positioning groove 210 is an arc groove, and the cross section of the positioning groove 210 is a major arc. It should be noted that the positioning groove 210 has a center line extending along the length direction thereof, the axis of the electrode 300 is perpendicular to the center line, and a plane defined by the axis of the electrode 300 and the center line is perpendicular to the preset plane.
Optionally, a fifth fixing hole 220 is further disposed on the positioning element 200, a portion of the positioning element 200 is inserted into the fourth fixing hole 124 of the second base 120, and the bolt 150 sequentially passes through the second fixing hole 114 and the fourth fixing hole 124 and is screwed into the fifth fixing hole 220, so that the base 100 and the positioning element 200 are connected.
Obviously, in other embodiments, the positioning member 200 and the base 100 may be connected in other ways, or the positioning member 200 and the base 100 may be integrally formed.
In other embodiments, the base 100 is further provided with a first protrusion 160 and a first recess 170, which are engaged with each other, and the adjacent electrostimulation devices 001 are inserted into and engaged with the corresponding first protrusion 160 and first recess 170. In other words, when a plurality of electrostimulation devices 001 are required to be used in cooperation, the connection of two adjacent electrostimulation devices 001 is realized by the first convex part 160 and the first concave part 170 on each electrostimulation device 001, so that the plurality of electrostimulation devices 001 are combined into a whole for convenient use. Optionally, the first protrusion 160 and the first recess 170 are in interference fit to improve the stability of the adjacent electrostimulation device 001.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
