Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Referring to fig. 1, fig. 2, fig. 3 and fig. 4, the present invention provides a technical solution: a minimally invasive lateral approach femoral retractor for total hip arthroplasty comprises a handle 1, a retractor 2 is arranged on the left side of the handle 1, a side plate 3 is arranged on one side, close to the retractor 2, of the rear side face of the handle 1, and the handle 1, the retractor 2 and the side plate 3 are integrally formed.

When the thighbone is adducted, after the external rotation, this drag hook 2 is placed in the thighbone back wall, 2 front ends of drag hook support at thighbone neck basal portion, protruding extension's curb plate 3 plays the effect of keeping off the protection in the thighbone on the muscle around the back wall, avoid the thighbone pulp cavity to contort muscle, only use the operation that operation can be accomplished to a drag hook 2 simultaneously, save operation space and operation assistant operation, the extension is curved handle 1 and keeps off the hip skin, skin tissue, especially to obese patient, can effectively increase the operation field of vision.

Specifically, a through hole 4 is formed on the surface of the handle 1 away from the drag hook 2.

The handle 1 is conveniently hung and stored by the through hole 4, so that the use is more convenient.

The working principle is as follows: when the femur is adducted and is externally rotated, the draw hook 2 is placed on the inner back wall of the femur, the front end of the draw hook 2 is propped against the base part of the femoral neck, the side plate 3 which is protrudingly extended is arranged on the muscle around the inner back wall of the femur, meanwhile, the operation can be completed by only using one draw hook 2, and the extending arc-shaped grip 1 blocks the subcutaneous and cutaneous tissues of the hip.

Example two

Referring to fig. 5 and fig. 6, the technical solution provided by the present embodiment is different from the technical solution in the first embodiment only in that: one side that the upper surface of handle 1 is close to through-hole 4 is seted up flutedly 5, strip groove 6 has been seted up in the left side of recess 5, draw-in groove 7 has been seted up in the left side of strip groove 6, the inner wall joint of draw-in groove 7 has cylinder 8, the back side fixed assembly of cylinder 8 has connecting rod 9, connecting

rod

9 and 3 fixed assemblies of curb plate, the fixed bull stick 10 that is equipped with in right side of cylinder 8, bull stick 10 is located strip inslot 6, the right side end fixed assembly of bull stick 10 has spheroid 11, spheroid 11 is located recess 5, the fixed rubber pad 13 that is equipped with in upper surface left side of handle 1, rubber pad 13 is located the front side of.

At the in-process rotation spheroid 10 that uses rotates at the inner wall of recess 5, spheroid 11 drives bull stick 10 at the pivoted in-process and rotates, bull stick 10 rotates in bar groove 6, bull stick 10 drives cylinder 8 and rotates in draw-in groove 7, cylinder 8 drives the swing of curb plate 3 through connecting rod 9, thereby adjust the swing angle of curb plate 3, it is more nimble in the time of the use, rubber pad 13 shelters from cylinder 8, rubber pad 13 can take place to deform and provide certain space for the rotation of connecting rod 9.

The front side of the ball 11 is provided with a rib 12.

The ribs 12 can increase the friction on the surface of the ball 11, facilitating the rotation of the ball 11.

The working principle is as follows: the inner wall that rotates spheroid 11 at recess 5 rotates, and spheroid 11 drives bull stick 10 at the pivoted in-process and rotates, and bull stick 10 rotates in bar groove 6, and bull stick 10 drives cylinder 8 and rotates in draw-in groove 7, and cylinder 8 drives 3 swings of curb plate through connecting rod 9 to adjust the swing angle of curb plate 3.
