Embodiment 1

[0058] Embodiment 1 (see Figure 1 to Figure 10 )

[0059] In this example, if Figure 7 As shown, the positioning member 31 is a spring, such as figure 2 As shown, the positioning member 31 is disposed on a side of the locking member 21 facing the pulse signal transmission member 1 . The matching device in this embodiment is easy to manufacture and low in cost.

[0060] Further, as Figure 7 As shown, the positioning member 31 can be a canted coil spring.

[0061] Specifically, the positioning groove 32 on the pulse signal transmission member 1 may be arc-shaped to fit the spring.

[0062] In this example, see Figure 8 , Figure 9 and Figure 10 , the positioning groove 32 on the pulse signal transmission member 1 can be a hump-shaped groove, or other suitable arc-shaped grooves.

[0063] Before the pulse signal transmission part is inserted into the top cover, please refer to the structure of the matching device image 3 . During use, the doctor inserts the puls...

Embodiment 2

[0067] Embodiment 2 (see Figure 11-Figure 20 )

[0068] In another specific embodiment of the present invention, as Figure 13 and Figure 14 As shown, the positioning member 31 is an elastic ball head, see for details Figure 14 , the elastic ball head includes a ball head 311 and an elastic member 312, the elastic member 312 connects the ball head 311 and the fastener 22; the elastic ball head is connected to the fastener 22 toward the One end of the pulse signal transmission part 1. Such as Figure 14 and Figure 18 As shown, the elastic ball head and the fastening screw form an elastic ball head fastening screw (also known as a ball head plunger). The bottom of the fastener 22 is provided with a mounting hole, and the positioning member 31 is inserted into the mounting hole. The spherical structure of the elastic ball head fastening screw cooperates with the spring in the hole to have a telescopic function.

[0069] Specifically, the elastic member 312 may be a sp...

Embodiment 3

[0078] The present invention also provides a pulse generator, such as figure 1 and Figure 11 As shown, the pulse generator includes a top cover 4 and a cooperating device according to the present invention, and the cooperating device is mounted on the top cover 4 . The top cover 4 is provided with a channel for inserting the pulse signal transmission part 1 . The locking part 21 is provided with a first through hole 211 for inserting the pulse signal transmission part 1 and a second through hole 212 for inserting the fastener 22. The first through hole 211 communicates with the passage on the top cover 4, and the second through hole 212 is connected with the top cover 4. The second through hole 212 intersects and communicates with the first through hole 211 . Generally, the axial direction of the second through hole 212 is perpendicular to the axial direction of the second through hole 211 .

Abstract

The invention relates to the technical field of medical instruments, in particular to a matching device for a pulse generator and the pulse generator. The matching device comprises a pulse signal transmission piece, a locking structure and a positioning structure; the locking structure comprises a locking piece and a fastening piece; the positioning structure comprises a positioning piece and a positioning groove which can be connected in a clamped mode, one of the positioning piece and the positioning groove is arranged on the pulse signal transmission piece, and the other one of the positioning piece and the positioning groove is arranged on the locking structure; when the positioning piece is connected with the positioning groove in a clamped mode, the pulse signal transmission piece reaches a set position; and the fastening piece is used for fixing the pulse signal transmission piece at the set position. According to the matching device for the pulse generator, the insertion condition of the pulse signal transmission piece can be fed back to a doctor through touch feeling or sound in the operation process of a patient, the operation pain of the patient is reduced, and operation medical resources are saved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a matching device for a pulse generator and the pulse generator. Background technique [0002] Implantable pulse generator kits are three types of medical devices, including common brain pacemakers, defibrillators, neuromodulation stimulators, etc. Among them, the pulse generator is the key component, and the top cover of the pulse generator is the interface for the pulse generator circuit to transmit signals to the outside. There is a structure in the top cover that can insert and fix the pulse signal transmission part, and then stimulate the target to the patient through the pulse signal transmission part. Points to transmit stimulus signals. [0003] During the surgical implantation of the pulse generator, the operation of inserting the pulse signal transmission part into the top cover has the following problems: [0004] Although the top cover is transparent, due to the obstr...
