Embodiment 1

[0031] Embodiment 1: A kind of fracture-free fixing belt set, from figure 1 It can be seen that the belt set is mainly composed of a collar piece and a rope, the rope can be a rope or a sideband, and the collar piece is a flat collar piece. The connection relationship between the rope belt and each collar piece can be as follows: figure 2 Shown in one-piece form, for example using a PVC plastic sheet. Or the end of the rope is pressed and fixed together with the collar piece, such as image 3 As shown, the end of the rope is fixed together with the stainless steel collar piece by crimping or gluing or fitting or other fixing means. or using as Figure 4 In the connection shown, the end of the rope is serially connected to the corresponding collar piece.

[0032] From figure 1 It can be seen from the figure that the two piercing nails are fixed on both sides of the fracture site respectively, and the ends of the two piercing nails respectively expose the bone. In this em...

Embodiment 2

[0035] Embodiment 2: On the basis of Embodiment 1, that is, on the basis of the four main collar pieces A, B, C and D being connected by ropes in turn to form a quadrilateral, or on the basis of an approximate 8-shaped structure, and on the basis of the two main collar pieces Auxiliary rope belts are respectively connected to the loop pieces A and B, and auxiliary loop pieces C' and D' are fixedly connected to the end of each auxiliary rope belt. From Figure 5It can be seen that the application of this program can not only fix the AD rope and BC rope on the front of the fracture area, but also fix the AD' rope and BC' rope on the back of the fracture area, so that the surrounding area of ​​the fracture can be fixed. fixed.

Embodiment 3

[0036] Embodiment 3: On the basis of embodiment 2, the auxiliary collar pieces C' and D' are replaced by flat collar pieces C" and D", respectively. Embodiment 2 usually needs to fix the nail vertically to the center of the backbone, or needs to choose a suitable fixing belt set. However, in this embodiment, an auxiliary rope loop structure that can be stretched and adjusted is designed, so that it is not necessary to strictly pay attention to the nailing position. When nailing, it only needs to meet the four main loop pieces A, B, C, and D when they are located on the front. The position (as in Example 1) is enough, and the AD" rope and BC" on the back can be stretched and adjusted to tension after being fitted.

[0037] Specifically, such as Figure 6 As shown, when the flat sleeve ring pieces C” and D” are used, it is also necessary to provide a locking mechanism for the flat sleeve ring pieces C” and D”.

[0038] From Figure 6 and Figure 7 It can be seen that a locki...

Abstract

The invention discloses a fracture bundling-free fixing band set. The fracture bundling-free fixing band set comprises at least two penetrating nails and main sleeve ring pieces, wherein the penetrating nails penetrate through and are fixed to two sides of a fracture part respectively, the main sleeve ring pieces are used for being connected to the ends, exposed out of the bone part, of the penetrating nails in a sleeving mode, the four main sleeve ring pieces A, B, C and D are sequentially connected through flexible rope bands to form a quadrangle, and the main sleeve ring piece D is symmetrically turned over along the AB line to form an approximately 8-shaped structure. The fracture bundling-free fixing band set is flat and can be rapidly fixed and applied; compared with an existing modethat ropes are repeatedly wound around the exposed ends of the two penetrating nails and finally bundled into knots, the mode used in the invention has the characteristics that the number of protruding portions is obviously reduced, the operation efficiency is improved, the operation difficulty is reduced, blood circulation is improved so that a patient can recover, and the comfort of the patientis improved.

Description

technical field [0001] The invention belongs to the technical field of fracture reduction and fixation tools, and in particular relates to a tool for flexible and binding-free fixation of fracture sites. Background technique [0002] The common surgical treatment methods for the fixation of femoral shaft fractures include plate fixation and intramedullary nail fixation. Plate fixation has the advantages of simple operation and short learning period, but the trauma is large and the probability of accidental injury is high. Many matching models are required. Healing, delayed healing, broken nails and broken plates occur from time to time, and the postoperative scars are large, which affects the appearance and does not conform to the principle of minimally invasive. The intramedullary nail adopts closed and minimally invasive technology. The locking intramedullary nail can prevent fracture rotation deformity, reduce the risk of implant fracture, reduce the surgical infection ra...
