 Prosthetic Aids (Artificial Limbs)

We are having State-of-the-art artificial limbs and best facilities in the world with us. Otto Bock artificial legs and arms are also available. Otto Bock is a German company who are world leaders in artificial limbs components.
Endolite artificial legs are also available.
Prosthetic aids are appliances fitted to patients who have lost their limbs due to any disease, accident or it may even be a congenital loss.
    Lower Limb Prosthesis: Lower Limb Prosthetic Aids are manufactured in fibreglass. These are fitted to following levels of amputations or loss:
* Through Hip
* Above Knee
* Through Knee
* Below Knee
* Through Ankle (Symes)
* Partial Foot (Chopart)
Miss. Sushma lost both her legs in 1988 when she was buried in snow in district Rorhu (H.P.). She is wearing both artificial legs. She was an inmate of Nevedac for about 12 years and lived independently and attends to her daily needs without any help. Now she is employed as a teacher in her native place at district Rorhu (H.P.).
Upper Limb Prosthesis : Upper Limb Prosthetic Aids are also manufactured in fibreglass. These are fitted to following levels of amputations or loss:
* Through Shoulder
* Above Elbow
* Through Elbow
* Below Elbow
* Through Wrist
* Partial Hand

 In case of 1 to 3 above, the Prosthesis is fitted with mechancal elbow which allows easy flexion at the prosthetic elbow joint. The Prosthesis, in case of 1 to 5 above, are fitted with either a Mechanical or Electronic Hand. For partial hand, only cosmetic hand can be fitted. In all above cases, prosthetic hand is covered with a PVC glove which has an appearance of a real hand.

Nevedac electromic hand :
   Nevedac Electronic Hand is working with microswitches, because an  alternative to the myo-electric prosthesis is the Switch  Control System.  In  this  system,  micro-switches  are  used  which  are activated by fitting these inside the socket where muscle  signal or  stump contact with the micro-switch, is most prominent.  This is located with the help of a Signal Tester, especially  designed in this Institution.
  The significant achievement in Nevedac Electronic Hand is that it has  been  fabricated from the locally available parts  and  that nothing has  been imported from outside India. The main consideration has been to keep its cost within the reach  of  an average Indianpatient, who can afford to pay. It is therefore  a high tech Prosthetic Hand at Low Cost.
  The electric  source for Nevedac Electronic Hand, is  six  Volts Nickle  Cadmium battarys, fitted within the prosthesis. When  the micro-switch is activated the current passes through the  Circuit Board  to  the  motor, which gives the  drive  to  the  specially fabricated   gear assembly. This results in opening of  all  four fingers  and  the  thumb. When the signal is  released  from  the switch, the fingers are closed. The gripping force is good and it can hold a glass full of  water very  comfortably.  The grip of this hand is enough  to  hold  an object of over TWO Kilograms. The fingers and palm are moulded in ABS. This is covered with a PVC cosmetic glove to give a  natural appearance  and to protect the hand mechanism and circuitry  from dust and moisture. The battery is charged with a special charger in about 15  hours. The life of the battery is about 2 years. The weight of this NEVEDAC motor powered hand is about 500 grams. The photo on the left shows a man welding with his right electronic hand.

Nevedac Microprocessor Controlled Prosthetic Hand System (under R&D): With this the cost of the Electronic hand increases by a reasonably small amount. The movement of the fingers and battery charging is controlled by the micro-processor. It also has certain features, which can be programmed to the patient's needs.
