Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bone fracture plates, and in particular relates to a low-profile radial locking bone fracture plate. Background Art
[0002] The low-profile radius locking plate is processed by a low-profile processing method to make its surface smooth without processing marks. The radius locking plate is used for radius fracture injuries. It is positioned at the fracture injury site to achieve locking bone fixation and facilitate radius recovery.
[0003] When the existing radius locking plate is used in fracture surgery, the locking plate is placed at the fracture site and then fixed with a locking screw. However, the following defects exist: (1) When the radius locking plate is used for radius locking bone fixation, the plate is placed at the fracture site, and then the screw is taken out, inserted into the hole and supported, and then screwed and tightened to lock the plate. However, the surgical operation process is time-consuming and cumbersome, which greatly increases the difficulty of radius plate locking surgery. For this reason, we propose a low-profile radius locking plate. Utility Model Content
[0004] The utility model aims to provide a low-profile radial locking bone plate to solve the problem that the radial locking bone plate proposed in the above background technology is inconvenient to use in surgery and increases the difficulty of surgery.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-profile radial locking plate, comprising a plate body, a mounting hole is provided on the surface of the plate body, a straightening sleeve is arranged inside the mounting hole, a rotation groove with a circular cross-section is provided on the outer wall of the straightening sleeve, a side block is provided on the inner side of the rotation groove, the side block is fixed on the inner wall of the mounting hole, a locking stud passes through the inside of the straightening sleeve, a straightening hole is provided on the surface of the locking stud, a straightening block is provided inside the straightening hole, and the straightening block is fixed on the inner wall of the straightening sleeve.
[0006] Preferably, the longitudinal section of the straightening sleeve is a circular structure, and the cross section of the straightening sleeve is a convex structure.
[0007] Preferably, a through hole is opened on the surface of the straightening block, a supporting rod passes through the interior of the through hole, and the supporting rod is fixed inside the straightening hole.
[0008] Preferably, the longitudinal section of the straightening block is a rectangular structure.
[0009] Preferably, the cross section of the locking stud is a T-shaped structure, and the longitudinal section of the locking stud is a circular structure.
[0010] Preferably, a spring is provided at one end of the straightening block, and the spring is sleeved on the outer wall of the supporting rod.
[0011] Preferably, the longitudinal section of the support rod is a circular structure, and the central axes of the support rod and the locking stud coincide with each other.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] (1) Through the designed supporting rod, straightening sleeve, straightening block, locking stud and side block, the straightening sleeve can be rotatably installed on the bone plate body through the cooperation of the side block and the rotating groove, and the locking stud is placed inside the straightening sleeve, and the straightening block is placed in the straightening hole on the surface of the locking stud, so that the locking stud will not fall off or separate in the straightening sleeve while being able to slide. In addition, the straightening block is fixed to the inner wall of the straightening sleeve, so that the locking stud can be rotated arbitrarily on the bone plate and can also slide. Therefore, the utility model reserves and straightens the locking stud on the bone plate. When the bone plate is fixed, there is no need to take the screw to perform the hole straightening operation, which greatly reduces the difficulty of using the bone plate for radial surgery. Through the designed spring, the spring is squeezed between the straightening block and the locking stud. When locking and fixing, the spring exerts an elastic squeezing effect on the locking stud, so that the end of the locking stud directly presses against the surface of the bone, further facilitating the locking and positioning efficiency.
