Embodiment 1

[0042] In this embodiment, a titanium plate with a loop of a lesser trochanter bone block comprises a titanium plate 1 and a wire loop 3; as figure 1 , the titanium plate 1 is a curved surface suitable for the surface of the lesser trochanter bone, and the outer circumference is smooth; the titanium plate 1 penetrates along its thickness direction to form two loop holes 11, and the loop 3 is threaded on the thread Loop holes 11 ; the two ends of the titanium plate 1 are symmetrically provided with toothed nails 12 , and the toothed nails 12 are arranged on the concave surface of the titanium plate 1 . The titanium plate 1 has a curved surface structure, a smooth outer circumference, and is equipped with a tooth nail 12, which can be stretched and adhered to the surface of the lesser trochanter bone, and solves the problem of fixing the lesser trochanter on the medial wall when traditional intramedullary fixation is used to treat unstable intertrochanteric fractures. .

Embodiment 2

[0044] In this embodiment, a foldable titanium plate with a loop for the lesser trochanter bone includes a titanium plate 1 and a wire loop 3; figure 2 , the titanium plate 1 includes a first folding plate 13 and a second folding plate 14, the first folding plate 13 and the second folding plate 14 are connected by a folding mechanism 15, and the folding mechanism 15 is hinged to each other through a rotating shaft The male and female slots are equipped with torsion springs to facilitate the folding and restoration of the titanium plate 1. The two loop holes 11 are symmetrically arranged on the first folding plate 13 and the second folding plate 14 with the center of the folding mechanism 15 respectively, and the two tooth nails 12 are also symmetrically arranged on the first folding plate 13 with the center of the folding mechanism 15 and the second folding plate 14 .

Embodiment 3

[0046] In this embodiment, a titanium plate with a loop of a lesser trochanter bone fragment and its assembly includes the foldable titanium plate with a loop in Example 2, and the assembly includes a nailer 2, and the nailer 2 is provided with a sleeve 22 and the delivery plate 23; the delivery plate 23 is hinged with the end of the sleeve 22, and there are two side plates extending outward from the center of the hinge point; the sleeve 22 is hollow, and a push rod 24 is provided inside, and the The push rod 24 is connected with the two side plates, and is used to control the two side plates to be folded toward the sleeve 22 or deployed outward. In this embodiment, the two side plates of the conveying plate 23 are arranged symmetrically around the hinge point, and the first folding plate 13 and the second folding plate 14 of the titanium plate 1 are arranged symmetrically around the folding mechanism 15 .

[0047] The nailer 2 is also provided with a handle 21, and the handle...

Abstract

The invention discloses a lesser trochanter bone block belt loop titanium plate and an assembly thereof. The lesser trochanter bone block belt loop titanium plate comprises a titanium plate body and a thread loop. The titanium plate is a curved surface matched with the surface of a lesser trochanter bone block; two thread loop holes are formed in the titanium plate in a penetrating mode in the thickness direction of the titanium plate, and the thread loop is arranged in the thread loop holes in a penetrating mode; tooth nails are arranged at the two ends of the titanium plate, and the tooth nails are arranged on the concave face of the titanium plate; and a folding mechanism is arranged in the middle of the titanium plate. The assembly comprises a nailing device and an outer side end titanium plate, and the nailing device is provided with a sleeve and a conveying plate; the conveying plate is hinged to the end of the sleeve, and two side plates extend outwards with the hinge point as the center; and the outer side end titanium plate is connected with the titanium plate through the thread loop.

Description

technical field [0001] The invention belongs to the technical field of orthopedic instruments, and in particular relates to a titanium plate with a loop of a lesser trochanter bone block and an assembly thereof. Background technique [0002] Intertrochanteric fracture is one of the most common fractures, more common in the elderly, often accompanied by lesser trochanter fracture. The medial intertrochanteric wall is the most important pressure-conducting part of the medial intertrochanteric bone cortex, and its integrity is directly related to the stability of the intertrochanteric fracture. The medial wall injury of intertrochanteric fractures can have a huge impact on the curative effect of internal fixation, and is one of the key factors that directly determine the success of internal fixation. In the treatment of unstable intertrochanteric fractures, intramedullary fixation has certain advantages, but it is still controversial. The use of DHS and intramedullary nails in...
