## Abstract

An amputated part holding apparatus has a contact member provided in a casing to define a particle charge chamber between the contact member and the casing. The contact member comes into pressing contact with an amputated part owing to increased pressure in the particle charge chamber. The chamber is charged with particles to generate pressing force. The amputated part holding apparatus is further provided with a particle supply unit including a particle charging device.

## Claims

### Claim 1

An amputated part holding apparatus comprising:
a casing;
a contact member provided in the casing to define a particle charge chamber between the contact member and the casing, the contact member being operable to come into contact with an amputated part owing to increased particles in the particle charge chamber; and
a plurality of expander members provided in the particle charge chamber for applying additional pressing forces to particles charged in the particle charge chamber, each of the expander members being connected with a tube ring;
wherein the casing is formed with a charging hole for charging particles into the particle charge chamber.

### Claim 2 (depends on 1)

The amputated part holding apparatus according to claim 1, wherein each of the expander member has an enclosed space for receiving a pressurized fluid.

### Claim 3

An amputated part holding apparatus comprising:
a casing;
a contact member provided in the casing to define a particle charge chamber between the contact member and the casing, the contact member being operable to come into contact with an amputated part owing to increased particles in the particle charge chamber; and
wherein the casing is formed with a charging hole for charging particles into the particle charge chamber and with a discharging hole, and
a particle supply unit including:
a particle storage chamber for storing particles;
a charging passage for connecting the charging hole of the casing with the particle storage chamber;
a discharging passage for connecting the discharging hole of the casing with the particle storage chamber.

### Claim 4 (depends on 3)

The amputated part holding apparatus according to claim 3, wherein the particle supply unit further includes a conveying device provided in the particle storage chamber for conveying particles from the particle storage chamber to the charging passage, and particles from the discharging passage to the particle storage chamber.

### Claim 5 (depends on 1)

The amputated part holding apparatus according to claim 1, wherein the particles are made of synthetic resin.

### Claim 6 (depends on 3)

The amputated part holding apparatus according to claim 3, further comprising a support unit for supporting the casing in such a way as to rotate in a predetermined axis.
