Abstract
The utility model relates to the field of prosthetics and particularly relates to a thigh socket. The upper end of the thigh socket is provided with a longitudinal opening and an ischium ramus accommodating device; the ischium ramus accommodating device is positioned at the internal rear side edge of the opening; the external side edge of the opening is folded inward and has a height greater than that of the ischium ramus accommodating device. Compared with a tough socket easy to incline in the prior art, the thigh socket provided by the utility model is capable of accommodating the upper and lower parts of a large rotor; the external side edge of the opening is folded inward, the thigh socket can apply the inward pressure to a femoral shaft, so that the ischium ramus accommodating device of the thigh socket and the outside form three-point fixation for synostosis, femoral abduction is avoided, and thus the stability of the thigh socket is improved.
Description
Technical field
This utility model relates to field of prosthetic limbs, in particular to transfemoral sockets.
Background technology
After above knee amputation operation, in order to allow patients with amputation again stand up, need to use transfemoral sockets to be assemblied in amputation portion, to support the body weight of patients with amputation.
In correlation technique, transfemoral sockets is quadrilateral socket, and the upper end of this receptive cavity offers horizontal opening.When this transfemoral sockets is arranged on to the amputation portion of patients with amputation, transverse opening coordinates with amputation portion, the easy abduction of femur, poor stability.
Utility model content
The purpose of this utility model is to provide transfemoral sockets, to solve the above problems.
A kind of transfemoral sockets is provided in embodiment of the present utility model, and the upper end of transfemoral sockets is provided with longitudinal opening and ramus of ischium containment means; Ramus of ischium containment means is positioned at the posterior edges of opening; The outer ledge of opening draw in to the inside and its height higher than the height of ramus of ischium containment means.
The transfemoral sockets that this utility model embodiment provides, compared with the transfemoral sockets easily rolling in prior art, its upper end is provided with opening and ramus of ischium containment means.When this transfemoral sockets is arranged on to amputation portion, the ramus of ischium containment means that is positioned at the posterior edges of opening contains ramus of ischium, the height of the outer ledge of opening is higher than the height of ramus of ischium containment means simultaneously, this transfemoral sockets closely contains trochiterian above and below, because the outer ledge of this opening draws in to the inside, transfemoral sockets can inwardly be exerted pressure to femoral shaft, make ramus of ischium containment means and the outside of this transfemoral sockets fixing to 3 of bone formation, avoid femur abduction, thereby improve the stability of this transfemoral sockets.
Accompanying drawing explanation
Fig. 1 shows the front view of the transfemoral sockets of this utility model embodiment;
Fig. 2 shows the rearview of the transfemoral sockets of this utility model embodiment;
Fig. 3 shows the internal view of the transfemoral sockets of this utility model embodiment;
Fig. 4 shows the external view of the transfemoral sockets of this utility model embodiment.
The specific embodiment
Below by specific embodiment, also by reference to the accompanying drawings this utility model is described in further detail.
A kind of transfemoral sockets providing for the present embodiment as shown in Figure 1, Figure 2, Figure 3 and Figure 4, the upper end of transfemoral sockets is provided with longitudinal opening 102 and ramus of ischium containment means 101; Ramus of ischium containment means 101 is positioned at the posterior edges of opening 102; The outer ledge 103 of opening 102 draw in to the inside and its height higher than the height of ramus of ischium containment means 101.
The transfemoral sockets that this utility model embodiment provides, compared with the transfemoral sockets easily rolling in prior art, its upper end is provided with opening and ramus of ischium containment means.When this transfemoral sockets is arranged on to amputation portion, the ramus of ischium containment means that is positioned at the posterior edges of opening contains ramus of ischium, the height of the outer ledge of opening is higher than the height of ramus of ischium containment means simultaneously, this transfemoral sockets closely contains trochiterian above and below, because the outer ledge of this opening draws in to the inside, transfemoral sockets can inwardly be exerted pressure to femoral shaft, make ramus of ischium containment means and the outside of this transfemoral sockets fixing to 3 of bone formation, avoid femur abduction, thereby improve the stability of this transfemoral sockets.
In addition, the forward edge 104 of opening 102 is consistent with the height of ramus of ischium containment means 101.This transfemoral sockets, installing and using in process, can not produce excessive pressure to femoral triangle, thereby has ensured the normal activity of hip joint.And because femoral triangle is that thigh is quiet, the position at tremulous pulse place, reduce the pressure to this position, thereby avoid affecting blood circulation.
Preferably, the forward edge 104 of this opening 102, to front side expansion, is avoided joint portion to cause excessive pressure.
Further, the posterior edges 201 of this opening 102 be open and its height lower than the height of ramus of ischium containment means 101.After this transfemoral sockets is installed, ramus of ischium containment means contains ramus of ischium, outer ledge closely contains trochiterian above and below, gluteus maximus may be compressed by posterior edges, and the transfemoral sockets of the present embodiment is after installation, posterior edges is open, and its height is lower than the height of ramus of ischium containment means, gluteus maximus can not be subject to compressing of posterior edges, and gluteus maximus is well discharged.
Further, the height of the inside edge 301 of opening is lower than the height of ramus of ischium containment means 101.Pubis has effectively been avoided in lower inside edge 301, avoids femoribus internus tenderness.
Use the transfemoral sockets tool of the present embodiment to have the following advantages: (1) hip joint can be freely movable.(2) lateral stability is good.(3) do not affect the blood circulation of deformed limb.(4) good looking appearance.Because the shape of the mouth as one speaks control section of opening is in strict accordance with the physiological structure design of skeleton trend and muscle, and gluteus maximus, rectus femoris and femoral triangle are carried out to earth pressure release, and are shaped as longitudinal ellipse, the wider limited guarantee of opening anteroposterior diameter hip joint freely movable.The earth pressure release at femoral triangle place has reduced, and pressure quiet to thigh, tremulous pulse makes blood circulation unaffected.Outside ramus of ischium containment means coordinates, greater trochanter containing part and greater trochanter below, to 3 power of femoral shaft pressure initiation to the inside, make femur keep interior receipts state, and then reach good lateral stability.Edge of opening and limbs are closely docile, good looking appearance.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
