Problems solved by technology

However, the prosthetic negative mold obtained by the above method often cannot fully take into account the force requirements of the patient's residual limb, resulting in the subsequent production of prosthetics still requires a secondary mold repair by technicians, and the process of adjusting the force of the residual limb through mold repair is cumbersome. Higher practical experience is required for technicians

Embodiment 1

[0037] refer to Figure 1-8, the prosthetic female model taking device in the present embodiment, comprises taking shape bucket 10 and several extruding mechanisms; The upper end of described taking type bucket 10 is open, and lower end is closed; Said several extruding mechanisms are evenly distributed in the On the side wall of the type barrel 10, it is used to squeeze different parts of the plaster of paris bandage on the residual limb respectively, so that the plaster of paris bandage and the residual limb are more fit; the extruding mechanism includes a screw rod 8 and a flexible pad sheet 7; one end of the screw 8 is provided with a limit piece 802, and the other end is provided with a bar-shaped bump 801; 10 threaded connection; the strip bump 801 is used to facilitate the rotation of the screw 8; the stopper 802 is provided with a connecting piece; the connecting piece is a barrel structure with one end open; the opening of the connecting piece The end is connected wi...

Embodiment 2

[0043] refer to Figure 9-11 , The difference between this embodiment and Embodiment 1 is that the extruding mechanism includes an air bag 15 and an air valve 16; The air bag 15 is inflated or deflated; the air bag 15 is arranged on the inner wall of the type-taking bucket 10 and communicates with the valve 16; the extrusion mechanism also includes a fourth pressure sensor 17, a central processing unit 6 and the first display 5; the central processing unit 6 is electrically connected with the fourth pressure sensor 17 and the first display 5 respectively; the fourth pressure sensor 17 is arranged on the outer wall of the air bag 15, and is used To detect the pressure between the outer wall of the airbag 15 and the plaster of paris bandage, generate a pressure electrical signal, and send the pressure electrical signal to the central processing unit 6; the central processing unit 6 is used to transmit the pressure The electrical signal is converted into a pressure digital signa...

Abstract

The invention discloses a prosthetic female model taking device, which comprises a taking barrel and several extruding mechanisms; the upper end of the taking barrel is open and the lower end is closed; the several extruding mechanisms are evenly distributed on the taking On the side wall of the type barrel, it is used to squeeze different parts of the plaster of paris bandage wound on the residual limb respectively, so that the plaster of paris bandage and the residual limb are more fit. By evenly arranging several extruding mechanisms on the side wall of the mold-taking bucket, when taking the female mold, the residual limb tied with a plaster of paris bandage is placed in the mold-taking bucket, and the several extrusion mechanisms are adjusted. The extruding mechanism squeezes the part of the plaster of paris that needs to be pressed, so that the plaster of paris bandage fits more closely with the residual limb, and distinguishes the magnitude of the force on different parts, so that the internal shape and The stress distribution of the residual limb is more consistent with the stress requirement of the residual limb.

Description

technical field [0001] The invention relates to a type-taking device, in particular to a type-taking device for a prosthetic female model. Background technique [0002] In the production process of the prosthesis, firstly, the residual limb should be taken to obtain the female mold for producing the prosthesis. In the process of taking the shape of the existing prosthetic female model, the plaster bandage is manually wound on the patient's residual limb, and pressure is applied to different parts respectively. After the plaster bandage is solidified and hardened, it is taken off to obtain The prosthetic female model. However, the prosthetic negative mold obtained by the above method often cannot fully take into account the force requirements of the patient's residual limb, resulting in the subsequent production of prosthetics still requires a secondary mold repair by technicians, and the process of adjusting the force of the residual limb through mold repair is cumbersome. ...
