Summary of the invention:
Defective for the prior art existence, the purpose of this utility model provides a kind of defects that can overcome, has anchor point few, by fixing patella, indirectly femoral head is fixed, prevent capital inward turning and turning up, easy to use, the higher improved knee joint fixture of comfortableness for patients.
The technical scheme in the invention for solving the technical problem is: a kind of improved knee joint fixture, key is that described improved knee joint fixture comprises a upper support frame and lower support frame, upper support frame and lower support frame can be fastened and connected mutually, be provided with gland on the described upper support frame, described gland is connected on the upper support frame by a gland adjusting lever is movable, described gland adjusting lever upper end is provided with a turning knob, and the bottom of described lower support frame is connected with a fixing head.In order further to prevent the bracing frame rotation, in described bracing frame lower end fixing head is set, strengthened the area of bottom, prevent that thigh from driving the fixture upset.
The bottom of described lower support frame is provided with inserting groove, is provided with the strip projection at fixing head accordingly.The bottom that described strip projection can be connected to the lower support frame is provided with in the inserting groove.
For fixing plate clamp being held in the lower end of bracing frame, the bottom of described lower support frame is trapezoidal, and described fixing head is provided with a pair of clamping swash plate.
In order to keep the ventilation of bracing frame inwall, guarantee the ventilative of patient's shank, be provided with a plurality of ventilation slots at the interior ancient piece of jade, round, flat and with a hole in its centre of described lower support frame.
Improved knee joint fixture of the present utility model, employing is fixed capital indirectly to the fixedly realization of patella, can prevent the femoral head rotation, can keep capital neutral position for the patient behind the artificial total hip arthroplasty, as postoperative auxiliary fixing device, has advantage easy to use, simple in structure.
Description of drawings:
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model the second example structure schematic diagram.
Fig. 3 is this utility model the 3rd example structure schematic diagram.
The specific embodiment:
As shown in Figure 1 to Figure 3, a kind of improved knee joint fixture, described improved knee joint fixture comprises a upper support frame 4 and lower support frame 5, upper support frame 4 and lower support frame 5 can be fastened and connected mutually, be provided with gland 3 on the described upper support frame 4, described gland 3 is by a gland adjusting lever 2 movable being connected on the upper support frame 4, and described gland adjusting lever 2 upper ends are provided with a turning knob 1, and the bottom of described lower support frame 5 is connected with a fixing head 6.It is triangle or other is close-shaped after described upper support frame 4 and 5 amalgamations of lower support frame, also can adopt semi-enclosed, structure such as C shape, the opening of certain width only need to be set, the thigh that guarantees human body can be placed into bracing frame just passable, between upper support frame 4 and lower support frame 5, adopt clip to connect, but the knee position of patient on the upper support frame 4, after bracing frame 4 and lower support frame 5 are fixing, can mobile gland 3, gland 3 is pressed together on the patella, fixing head 6 is arranged on the bottom of lower support frame 5, fixing head 6 adopts separable connected mode with lower support frame 5, fixing head 6 can strengthen the area of fixture bottom, prevents that the patient from relying on the strength of thigh to make the fixture upset, cause capital abduction or in turn over, keep capital neutral position, further guarantee the effect of operation.
The bottom of described lower support frame 5 is provided with inserting groove, and correspondence is provided with the strip projection at fixing head 6.The bottom that described strip projection can be connected to the lower support frame is provided with in the inserting groove.Lower support frame 5 and fixing head 6 can adopt the fixed form of grafting, when in use, can first patient's thigh be placed in bracing frame, then control gland adjusting lever 2 and move down, arrive till the compression patella, and then place into fixing head 6 in the bottom of lower support frame.
The bottom of described lower support frame 5 is trapezoidal, and described fixing head 6 is provided with a pair of clamping swash plate 61.Clamping swash plate 61 has advantage simple in structure, easy to assembly.Only lower support frame 5 need to be connected on the fixing head 6 and get final product.
In order to keep the ventilation of bracing frame inwall, guarantee the ventilative of patient's shank, be provided with a plurality of ventilation slot 51 at the interior ancient piece of jade, round, flat and with a hole in its centre of described lower support frame 5.Ventilation slot 51 is the length direction along bracing frame, directly to setting.Preferably, can yielding rubber or cotton be set at the interior ancient piece of jade, round, flat and with a hole in its centre of lower support frame 5, soften the contact surface of thigh and bracing frame, prevent from causing the discomfort such as pain of skin.
For the bracing frame of the semi-closed structures such as C font, fixing head 6 is fixed the patient after can being fixed on first on the bracing frame again.
The second embodiment as shown in Figure 2, the turning knob 1 at its top are circular, and the bottom of lower support frame 5 is connected with a fixing head 6 by method of clamping, and other structure is all identical with embodiment one.
