Problems solved by technology

[0004] The disadvantage of this device is that the subcutaneously implantable receiving unit is inconvenient and even painful for the patient, for example if it is to be implanted for a long time
[0005] In addition, such a receiving unit connected to a wire is vulnerable to damage, for example, during surgical implantation
Once the device is damaged, it is difficult to replace
In most cases, the entire implant must be removed or replaced, resulting in undesirable cost and operating time and the risk of re-operating the patient

Embodiment Construction

[0019] According to FIG. 1, the device R according to the invention for controlling, regulating and / or putting into use a working implant 1 There is a receiving unit 2 which can be controlled contactlessly via a transmitting unit 3 . In a preferred embodiment, the receiving unit 2 has a circular cross-section and is elongated, which is provided at the end with a flange 4 which is connected to the receiving unit 2 on the end side. Furthermore, the flange 4 preferably also has a circular cross-section and has corresponding busbars, coil elements or the like in order to transmit data and / or energy from the receiving unit to the implant 1 . A thread 5 is connected with the flange 4, and the thread is an external thread. The thread 5 preferably has a centering mechanism (not shown in detail here) in order to center and in particular position the flange 4 on the corresponding contact surface 6 of the implant 1 particularly precisely. Energy transmission and / or data transmission ca...

Abstract

In a device for controlling, adjusting and / or commissioning a working implant, in particular a distraction treatment device for fractures, the receiving unit (2) can be mounted directly releasably in the implant (1) or with The implants (1) are connected. The device can be implanted together with a receiving unit (2) and receive data and / or energy from the outside via a transmitting unit (3).

Description

technical field [0001] The invention relates to a device for controlling, regulating and / or enabling a working implant, in particular a distraction treatment device for fractures, which can be implanted together with a receiving unit and receives data and / or energy from the outside via a transmitting unit. Background technique [0002] Devices for controlling, regulating and / or enabling such working implants, in particular fracture distraction therapy devices, are known and used in the market in various forms and designs. It is primarily used for distraction of any bone, bone part, bone segment, and also for insertion into the medullary cavity of a bone. [0003] It is known in the prior art, for example, that a plug is connected to the implant, which plug leads to a subcutaneously implantable receiving unit, which can be activated from the outside without contact by a transmitting unit, for example mechanically. [0004] A disadvantage of such devices is that the subcutane...
