Abstract
The utility model relates to an implanted type heart pacemaker pulse generator. A titanium outer housing of the utility model is composed of a left halt housing and a right half housing, a function circuit of the pulse generator is positioned in the left and the right two half housings, and an insulator is arranged between the top ends of the left and the right to half housings. An outer leading wire is welded on the leading wire end in the insulator through spot weld, the left and the right two half housings are welded into integration, and the top ends and the insulator are welded into integration. The titanium outer housing of the utility model is simple to process, and the assembly and the debugging of the function circuit part are easy to carry out. Simultaneously, space in the housing is fully utilized, and useless weight is eliminated, so that the volume of a heart pacemaker can be smaller, and the weight can be lighter.
Description
This utility model relates to a kind of implantable cardiac pacemaker pulse generator, belongs to electronic medical equipment manufacturing technology field.
The implantable cardiac pacemaker is made up of pulse generator and electrode catheter, and the pulse signal of pulse generator granting transfers to heart and cardiac stimulus pace-making via electrode catheter, and the exciting signal of heart is also delivered to cardiac pacemaker by electrode catheter.Cardiac pacemaker pulse generator shell is the Titanium material, adopt titanium plate stretching forming technique profile to be flat Hu reed shape, this structure has been brought very big inconvenience to assembling always, and inner chamber must leave the space, the titanium thickness of the shell is also thicker, has increased the volume and weight of pacemaker.And that the medical apparatus and instruments of implant into body is made every effort to volume is little, in light weight, helps undergoing surgery and reaching satisfactory therapeutic effects.
The purpose of this utility model is to design a kind of implantable cardiac pacemaker pulse generator, its titanium shell mechanism is easy to carry out the assembling and setting of functional circuit part, can make full use of the intravital space of shell simultaneously, eliminates useless weight, make the cardiac pacemaker volume littler, weight is lighter.
This utility model design: a kind of implantable cardiac pacemaker pulse generator, comprise pulse generator functional circuit (1), insulator (2) and outer lead (3), on the lead end (6) in outer lead (3) the spot welding insulator (2), the titanium shell of pulse generator is made up of a left side half shell (4) and right half shell (5), pulse generator functional circuit (1) is positioned at a left side, in the right two halves shells (4) (5), insulator (2) is arranged on a left side, between right two halves shells (4) (5) top, an and left side, right two halves shells (4) (5) are welded as a whole, and its top and insulator (2) are welded as a whole.
This utility model is compared with prior art: the shaping of two halves shell titanium shell is easier than the processing of monolithic devices shell, as long as by common processing technique, can finish through operations such as blanking, punching press, annealing, shaping, punchings.In addition, such pulse generator titanium shell is easy to carry out the assembling and setting of functional circuit part, is easy to welding and sealing behind the assembling and setting again, can make full use of space in the housing simultaneously, eliminates useless weight, makes the cardiac pacemaker volume littler, and weight is lighter.
Fig. 1 is a structure cutaway view of the present utility model.
1 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of implantable cardiac pacemaker pulse generator, comprise pulse generator functional circuit (1), insulator (2) and outer lead (3), on the lead end (6) in outer lead (3) the spot welding insulator (2), the titanium shell of pulse generator is made up of a left side half shell (4) and right half shell (5), pulse generator functional circuit (1) is positioned at left and right two halves shell (4) (5), insulator (2) is arranged between left and right two halves shell (4) (5) top, and left and right two halves shell (4) (5) is welded as a whole, and its top and insulator (2) are welded as a whole.
Manufacture method:
(1), adopt operations such as blanking, punching press, annealing, shaping, punching to carry out the shaping processing of two halves shell titanium shell, and behind cleaning and sterilizing, use;
(2), after assembling and settings such as functional circuit part, insulator are finished, the two halves shell is fastened, adopt program control four-dimensional linkage control system and laser welding system that two halves shell joint seam, two halves shell and insulator seam are sewed up welding, make it firmly to connect as one and guarantee sealing, the outer lead of spot welding simultaneously.
(3), the pulse generator titanium shell that will finish assembling and welding hunts leak, the leak detection result meets and changes next procedure over to after the cardiac pacemaker technical standard requires and get final product.
Claims (1)
1, a kind of implantable cardiac pacemaker pulse generator, comprise pulse generator functional circuit (1), insulator (2) and outer lead (3), on the lead end (6) in outer lead (3) the spot welding insulator (2), it is characterized in that: the titanium shell of pulse generator is made up of a left side half shell (4) and right half shell (5), pulse generator functional circuit (1) is positioned at left and right two halves shell (4) (5), insulator (2) is arranged between left and right two halves shell (4) (5) top, and left and right two halves shell (4) (5) is welded as a whole, and its top and insulator (2) are welded as a whole.
