Description

Technical Field

[0001] The utility model relates to an anti-slip hip joint ball head spreading pliers. Background Art

[0002] The human hip joint is a spherical joint consisting of a spherical femoral head and a bowl-shaped acetabulum. It forms the joint between the thighbone (femur) and the pelvis. Both the spherical surface and the inner surface of the bowl are covered with smooth cartilage, and the synovial bursa secretes mucus to minimize friction. When the hip joint becomes diseased, the cartilage loses its smoothness, the synovial bursa becomes inflamed and atrophies, and the joint no longer functions smoothly.

[0003] During hip surgery, the acetabulum often needs to be expanded to facilitate the reassembly of the femoral head and acetabulum, so as to facilitate the insertion of the femoral head. Currently, this is done by directly expanding the acetabulum with a expander, which can easily damage the acetabulum and cause slippage during contact, affecting the normal progress of the surgery and resulting in poor results. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a non-slip hip joint ball head distraction forceps with a simple, reasonable and reliable structure, which can be easily replaced to ensure safety and hygiene. At the same time, it can effectively avoid slipping during distraction, avoid hard contact, and improve the success rate and safety of the operation.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an anti-slip hip joint ball head distraction pliers, including a pliers handle, a gill axis screw and a support spring, the pliers handle includes a first pliers handle and a second pliers handle, the front inner sides of the first pliers handle and the second pliers handle are connected by a gill axis screw, the support spring includes a first support spring and a second support spring, the front ends of the first support spring and the second support spring intersect, and the rear ends are respectively fixed to the rear inner sides of the first pliers handle and the second pliers handle by support spring screws, the first pliers handle and the second pliers handle are respectively provided with U-shaped openings in the middle of the ends, and the first pliers handle and the second pliers handle are respectively provided with anti-slip strips on the outer sides of the two ends of the U-shaped openings.

[0006] In a preferred embodiment of the present invention, the outer side surfaces at both ends of the U-shaped opening are respectively concavely provided with convex sliding grooves along the opening direction.

[0007] In a preferred embodiment of the present invention, the anti-slip strip is arranged in a strip-shaped structure and a convex positioning strip is provided at the bottom corresponding to the convex sliding groove.

[0008] In a preferred embodiment of the present invention, a gasket is provided on the transverse contact surface of the convex positioning strip and the convex sliding groove.

[0009] In a preferred embodiment of the present invention, anti-slip stripes are provided on the upper surface of the anti-slip strip.

[0010] In a preferred embodiment of the present invention, the anti-slip strip is made of flexible rubber.

[0011] The beneficial effects of the utility model are as follows: the anti-slip hip joint ball head distraction pliers pointed out by the utility model have a simple, reasonable and reliable structure, can be easily replaced, and ensure safety and hygiene. At the same time, it can effectively avoid slipping during distraction, avoid hard contact, and improve the success rate and safety of the operation. BRIEF DESCRIPTION OF THE DRAWINGS
