Embodiment Construction

[0049] See Figure 1 to Figure 9 , A steel wire circling fixing device, comprising a first steel wire guiding device 1, a second steel wire guiding device 2, a steel wire tightening and breaking device 3.

[0050] The first wire guiding device 1 includes a first sleeve 12 and a first lance 14.

[0051] The first sleeve 12 includes a cylindrical first outer cylinder 122 and a first sleeve handle 124 provided at the rear end of the first outer cylinder 122.

[0052] The first sleeve handle 124 includes a first sleeve handle extension piece 1242 perpendicular to the first outer cylinder 122.

[0053] The first outer cylinder 122 and the first sleeve handle 124 are provided with a linear first outer cylinder opening 126 parallel to the central axis.

[0054] The first outer cylinder opening 126 penetrates the first sleeve handle 124, and a first sleeve handle opening 1244 is formed at the first sleeve handle 124.

[0055] The first lancet 14 includes a cylindrical first inner barrel 142 and...

Abstract

The invention discloses a steel wire cerclage fixing device which comprises a first steel wire guide device, a second steel wire guide device and a steel wire screw-breaking device, wherein the steel wire screw-breaking device comprises an outer sleeve and an inner core; the outer sleeve comprises a holding part; and the inner core comprises a rotary handle and a working rod. A groove parallel to the central axis of the rod body is arranged on the two sides of the working rod respectively; the rear end of the working rod is connected with the rotary handle; the front end of the working rod is divided into three parts: a reamer part at the middle is vertical to the rod body, and the steel wire locking parts on the two sides are convex-arc inclined planes; the far end of each convex-arc inclined plane is connected with the reamer part; the near end of each convex-arc inclined plane is not connected with the reamer part; and the convex-arc inclined planes are connected with the grooves on the two sides of the rod respectively and extend. In the invention, the steel wire screw-breaking device can screw and then break the steel wire; and the steel wire cerclage fixing device disclosed by the invention has multiple functions, is convenient to use and clean, and can minimize the wound of a patient.

Description

Technical field [0001] The invention relates to an orthopedic surgical instrument, which is applied to cases of comminuted fractures, and successfully achieves functional reduction and firm fixation of displaced fracture pieces under closed reduction and minimally invasive internal fixation operations, and solves the problem of fractures under closed conditions The problem that broken pieces cannot be reset ideally. Background technique [0002] For the wire fixation of fracture fragments (including temporary fixation and long-term fixation), there has been no special equipment (or equipment). In the past, in order to achieve functional reduction and effective fixation of bone fragments, a skin incision of at least 4 to 5 cm must be made in the local area where the fragments are located, and then the steel wire can be directly inserted by hand for surround fixation, basically in direct view In this way, it will inevitably cause unnecessary “collateral damage (mainly damage to th...
