Problems solved by technology

Under the condition that the structural strength of the surgical hole remains unchanged, the method of increasing the surgical suture hole will increase the volume of the polymer material connector, which will affect the comfort of implantation. The method of reducing the axial length of the surgical suture hole will be in a certain The volume squeezes the space of other parts in the polymer connector, which is not conducive to the arrangement of antennas, electrode connectors, and electrode connecting wires in the polymer connector.

Embodiment Construction

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are intended to facilitate the understanding of the present invention, but do not limit it in any way.

[0044] In this embodiment, an implantable cardiac pacemaker pulse generator is taken as an example to describe the structure of the curved hole for surgical suture.

[0045] The main structure of the cardiac pacemaker pulse generator 100 includes two parts: a metal sealed casing and a polymer connector. Such as figure 1 and figure 2 As shown, in this embodiment, the metal sealed shell is a titanium shell 120 , and the polymer connector is an epoxy resin connector 110 .

[0046] The epoxy resin connector 110 contains a feedthrough wire 115 , a connecting wire 116 , a round insert 111 , a square insert 117 , a silicone sealing plug 112 , a Bluetooth antenna 114 , and an electrode wire cavity 11...

Abstract

The invention discloses a surgical suture bent hole structure of an implantation device and a forming method of the surgical suture bent hole structure, and belongs to the field of electronic medical manufacturing. The implantation device comprises a metal sealing shell and a macromolecule connector which are connected with each other, and a plurality of parts and electrode circuits are arranged in the macromolecule connector; the macromolecule connector is provided with at least one operation suture hole penetrating through the macromolecule connector between the gaps where the parts and the electrode circuit are arranged, and the operation suture hole is of a bent hole structure. The surgical suture hole in the macromolecular connector is designed to be of the bent hole structure, so that the radian of the surgical suture hole is close to that of a surgical suture needle, a doctor can operate the surgical suture hole easily during surgery. Meanwhile, the tensile strength of the macromolecular connector is improved while the unit sectional area of the surgical suture bent hole is reduced.

Description

technical field [0001] The invention belongs to the field of electronic medical manufacturing, and in particular relates to a surgical suture curved hole structure of an implant device and a forming method thereof. Background technique [0002] Currently, implantable medical devices are widely used to treat diseases of the nervous system and cardiac system. Including but not limited to implantable cardiac pacemaker, implantable cardioverter defibrillator (ICD), cardiac resynchronization therapy defibrillator (CRT-D), cardiac resynchronization therapy pacemaker (CRT-P) , implanted brain pacemaker, implanted spinal cord stimulator, implanted sacral nerve stimulator, implanted vagus nerve stimulator, etc. [0003] An implantable cardiac pacemaker is an electronic therapy device that is implanted in the patient's body for a long time. The pulse generator sends out electric pulses powered by batteries, and through the conduction of wire electrodes, it stimulates the myocardium i...
