Detailed Description

The present invention will be described in detail below with reference to embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

As shown in fig. 1 to 3, insertion holes 11 for inserting the extension leads 2 are provided in the pulse generator 1, and a plurality of connection structures 3 are also provided in the pulse generator 1, the center lines of the connection holes 33 of the plurality of connection structures 3 are identical and all constitute parts of the insertion holes 11, so that, if it is desired to connect the extension leads 2 to the pulse generator 1, it is only necessary to insert the extension leads 2 along the insertion holes 11. alternatively, the extension leads 2 are circular in cross section, and the insertion holes 11 are also circular in cross section.

Embodiment of the present invention provides connection structures 3 for connecting extension leads 2, where the connection structures 3 are provided with connection holes 33 for inserting the extension leads, as shown in fig. 4-8, a plurality of holes 34 are provided along the circumference of the connection holes 33, and an elastic member 36 and a bump 35 are sequentially provided along the holes 34 toward the connection holes 33, where the holes 34 may be uniformly distributed along the circumference of the connection holes 33, for example, in fig. 5 and 6, four holes 34 are uniformly distributed along the circumference of the connection holes 33, alternatively, the cross section of the holes 34 may be regular shapes (e.g., square, circle, etc.), and the cross section of the connection holes 33 may be circular, etc.

Here, in fig. 5 and 6, the direction of the dotted arrow is the direction toward the connection hole 33, and it is understood that "the direction toward the connection hole" at different portions is not , and similarly, for a specific portion, the direction opposite to the dotted arrow is the direction away from the connection hole 33, and in the hole 34, the elastic member 36 and the projection 35 are sequentially arranged along the direction of the dotted arrow.

When pressure is applied to the lug 35 to depart from the connecting hole 33, the lug 35 can move along the hole 34 to depart from the connecting hole 33 and compress the elastic part 36; when pressure which is deviated from the connecting hole 33 is not applied to the bump 35, the elastic part 36 can push the bump 35 into the connecting hole 33, and the part of the bump 35 which is exposed to the connecting hole 33 is an arc-shaped curved surface.

Here, when the projection 35 is not pressed away from the attachment hole 33, the elastic member 36 is able to push the projection 35 into the attachment hole 33, it being understood that this is necessary to ensure that the projection 35 does not "excessively" extend into the attachment hole 33 (e.g., the projection 35 is entirely inserted into the attachment hole 33, and the elastic member 36 is also partially inserted into the attachment hole 33), some means is required to prevent this, for example, 1, ends of the elastic member 36 remote from the attachment hole 33 are fixedly attached to the attachment structure, and ends of the attachment projection 35 are fixedly attached, so that the projection 35 can be prevented from "excessively" extending into the attachment hole 33 by controlling the dimensions of the elastic member 36 and the projection 35 in the radial direction (i.e., the radial direction of the attachment hole 33), and 2, it being understood that the hole 34 is in communication with the attachment hole 33, i.e., they have an intersection, so that the size of the intersection can be controlled, i.e., the size of the intersection is smaller than the projection 35, so that the projection 35 can be prevented from "excessively" extending into the attachment hole.

Here, when the bump 35 is not pressed away from the connection hole 33, a portion exposed to the connection hole 33 is an arc-shaped curved surface, and the size of the cross section of the bump 35 is smaller toward the connection hole 33, thereby ensuring smooth insertion of the extension wire 2 into the connection hole 33.

Here, the step of connecting the extension wire 2 to the pulse generator 1 may include:

step 1: preparing the extension lead 2 and the pulse generator 1, at which time, in the connection structure 3 in the pulse generator 1, since the bump 35 is not pressed away from the connection hole 33, the elastic member 36 can push the bump 35 into the connection hole 33;

step 2: when the extension lead 2 is inserted into the connection hole 33, since the portion of the bump 35 exposed to the connection hole 33 is an arc-shaped curved surface, the extension lead 2 applies a pressure to the bump 35 away from the connection hole 33 during the insertion process, so that the bump 35 moves away from the connection hole 33 and compresses the elastic member 36.

Here, it can be understood that the steps 1 and 2 are very simple and easy to manufacture, and after the step 2 is completed, the elastic member 36 applies a pressure to the bump 35 toward the connection hole 33, thereby enabling the bump 35 to be tightly pressed against the extension wire 2. Alternatively, the extension wire 2 is provided with a groove on the outer surface thereof to be engaged with the bump 35, the extension wire 2 and the connection hole 33 are engaged with each other, for example, the cross section is circular, the diameter of the extension wire 2 is smaller than that of the connection hole 33, and the absolute value of the difference is smaller than a preset value or the like.

Here, since the bumps 35 are distributed along the circumferential direction of the connection hole 33 and the number thereof is plural, even if some of the elastic members 36 are reduced in elastic force, the remaining bumps 35 can tightly press the extension wire 2 extending into the connection hole 33.

Optionally, the center line of the connecting hole 33 intersects and is perpendicular to the center line of the hole 34.

Preferably, the bump 35 is an elastic round ball.

Preferably, the elastic member 36 is a spring.

Optionally, the size of the intersection of the hole 34 and the connecting hole 33 is smaller than the diameter of the round ball.

Here, the hole 34 intersects the connecting hole 33 and there are intersections, and since the size of the intersections is smaller than the diameter of the round ball, only part of the spherical surface of the round ball can extend into the connecting hole 33. as shown in FIGS. 5 and 6, the outline of the hole 34 near the connecting hole 33 can be matched with the round ball, which is more secure, and the hole 34 is separated from the connecting hole 33 by cylinders, and the diameter of the cross section of the cylinders can be equal to the diameter of the round ball, so that the round ball can move only along the radial direction of the connecting hole 33, but not along the axial direction of the connecting hole 33.

Here, the end of the hole 34 communicates with the connecting hole 33, and the other end may extend to the outer space of the connecting structure 3 at in the direction away from the connecting hole 33, so that, in production, the projection 35 and the elastic member 36 may be sequentially fitted in the direction toward the connecting hole 33, and then the portion where the hole 34 intersects with the outer space may be sealed (for example, the portion where the hole 34 is provided with a screw thread near the intersecting portion may be sealed with a screw).

Here, the sidewall of the connection hole 33 may be divided into two parts: outer wall 31 and inside wall 32, inside wall 32 sets up in outer wall 31, and fix through fixing device between inside wall 32 and the outer wall, the space that forms in the middle of the inside wall 31 is connecting hole 33, and the part that hole 34 is close to connecting hole 33 sets up in inner wall 32, and the part that hole 34 kept away from connecting hole 33 sets up in outer wall 31, therefore, when producing, can install the part that is located in outer wall 31 in hole 34 in proper order with elastomeric element 36 and ball, then insert inside wall 32 in outer wall 31, later fix inner wall 32 and outer wall 31 through fixing device.

Preferably, the intersection of the hole 34 and the connecting hole 33 matches with the round ball, and the size of the intersection is smaller than the diameter of the round ball.

Preferably, the elastic ball is made of a conductive silica gel material.

Preferably, the elastic ball at least comprises a metal spring, and the metal spring at least forms a part of the bump 35 exposed to the connection hole.

Optionally, the bump 35 is made of metal.

Optionally, the bump 35 is made of conductive silicone.

Alternatively, the projection 35 is fixedly connected to the elastic member 36.

The embodiment of the invention also provides pulse generator implanted in body, and the pulse generator is provided with the connecting structure 3.

The second embodiment of the present invention provides connection structures 3 for connecting extension wires 2, where the connection structure 3 is provided with a connection hole 33 for inserting the extension wire, as shown in fig. 7-10, a plurality of holes 34 are provided along the circumference of the connection hole 33, and a bump 35 is provided in the hole 34, where the plurality of holes 34 may be uniformly distributed along the circumference of the connection hole 33, for example, in fig. 9 and 10, four holes 34 are uniformly distributed along the circumference of the connection hole 33, alternatively, the cross section of the holes 34 may be regular shapes (e.g., square, circle, etc.). the cross section of the connection hole 33 may be circular, etc.

When pressure is applied to the bump 35 away from the connection hole 33, the bump 35 is compressed and has elastic force toward the connection hole 33; when pressure which is deviated from the connecting hole 33 is not applied to the bump 35, the bump 35 is exposed in the connecting hole 33, and the part exposed in the connecting hole 33 is an arc-shaped curved surface.

Here, when the projection 35 is not pressed away from the attachment hole 33, the projection 35 returns to its normal shape and is thus partially exposed to the attachment hole 33, it being understood that this is necessary to ensure that the projection 35 does not "over" extend into the attachment hole 33 (e.g., the projection 35 fully enters the attachment hole 33), and that some means is required to prevent this, for example: the holes 34 are in communication with the connection holes 33, i.e. they have an intersection, and the projection 35 can be prevented from "over" extending into the connection hole 33 by controlling the size of the intersection, i.e. the size of the intersection is smaller than the size of the projection 35.

Here, when the bump 35 is not pressed away from the connection hole 33, a portion exposed to the connection hole 33 is an arc-shaped curved surface, and the size of the cross section of the bump 35 is smaller toward the connection hole 33, thereby ensuring smooth insertion of the extension wire 2 into the connection hole 33.

Here, the step of connecting the extension wire 2 to the pulse generator 1 may include:

step 1: the extension conductor 2 and the pulse generator 1 are ready, at which time, in the connection structure 3 in the pulse generator 1, the bumps 35 have a partial surface exposed in the connection holes 33, since the bumps 35 are not subjected to a pressure away from the connection holes 33

Step 2: when the extension lead 2 is inserted into the connection hole 33, since the portion of the bump 35 exposed to the connection hole 33 is an arc-shaped curved surface, the extension lead 2 applies a pressure to the bump 35 away from the connection hole 33 during the insertion process, and the pressure compresses the bump 35.

Here, it can be understood that the steps 1 and 2 are very simple to manufacture, and the bump 35 has an elastic force toward the connection hole 33 after the step 2 is completed, so that the bump 35 can be tightly pressed against the extension wire 2. Alternatively, the extension wire 2 is provided with a groove on the outer surface thereof to be fitted with the bump 35, the extension wire 2 and the connection hole 33 are fitted with each other, for example, both are circular in cross section, and the diameter of the extension wire 2 is smaller than that of the connection hole 33, and the absolute value of the difference is smaller than a preset value or the like.

Here, since the bumps 35 are distributed along the circumferential direction of the connection hole 33 and the number thereof is plural, even if some of the bumps 35 become small in elastic force, the rest of the bumps 35 can tightly press the extension wire 2 extending into the connection hole 33.

Preferably, the center line of the connecting hole 33 intersects and is perpendicular to the center line of the hole 34.

Preferably, the bump 35 is an elastic round ball.

Optionally, the size of the intersection of the hole 34 and the connecting hole 33 is smaller than the diameter of the round ball.

Here, the hole 34 intersects the connecting hole 33 and there may be intersections, and since the size of the intersections is smaller than the diameter of the sphere, only part of the spherical surface of the sphere can extend into the connecting hole 33. As shown in FIGS. 9 and 10, the contour of the hole 34 near the connecting hole 33 can be matched to the sphere, which is more secure, and optionally, the hole 34 is spherical.

Here, the sidewall of the connection hole 33 may be divided into two parts: the ball mounting structure comprises an outer side wall 31 and an inner side wall 32, wherein the inner side wall 32 is arranged in the outer side wall 31, the inner side wall 32 and the outer side wall 31 are fixed through a fixing device, a space formed in the middle of the inner side wall 31 is a connecting hole 33, a part of a hole 34 close to the connecting hole 33 is arranged in the inner side wall 32, and a part of the hole 34 far away from the connecting hole 33 is arranged in the outer side wall 31.

Preferably, the intersection of the hole 34 and the connecting hole 33 matches with the round ball, and the size of the intersection is smaller than the diameter of the round ball.

Preferably, the elastic ball is made of a conductive silica gel material.

Preferably, the elastic ball at least comprises a metal elastic sheet, and the metal elastic sheet at least forms the part of the lug exposed to the connecting hole

Optionally, the portion of the bump 35 exposed to the connection hole 33 is formed by metal elastic sheets, where the number of the metal elastic sheets may be or more, when the number is , the metal elastic sheets are arc-shaped curved surfaces facing the connection hole 33, and when the number is multiple, the metal elastic sheets jointly form arc-shaped curved surfaces facing the connection hole 33.

Optionally, the bump 35 is spherical as a whole, and a part of the sphere of the bump 35 exposed to the connection hole is hollow, and the rest part of the sphere is hollow or solid. Here, since the metal dome moves away from the connection hole 33 when being compressed, a portion of the protrusion 35 exposed to the connection hole 33 needs to be hollow, thereby leaving a movement space for the metal dome; and the remaining portion may be hollow or solid, and when hollow, the weight of the entire joint structure can be reduced.

Alternatively, the bump 35 may also be metal elastic sheets, which are clamped in the hole 34 and have part of their surfaces exposed in the connection hole 33,

the embodiment of the invention also provides pulse generator implanted in body, and the pulse generator is provided with the connecting structure 3.
