Abstract

The utility model discloses a fixed tail clip in a medullary cavity, which has two structural forms. The first structural form is as follows: one end of the tail clip is a fixing part with a round hole, the other end of the tail clip is an arch bridge-shaped buckling part, and the fixing part and the buckling part are integrally formed. The second structural form is as follows: the two ends of the tail clip are symmetrical annular fixing parts, and the two fixing parts are connected by two strip-shaped buckling parts and can be bent. During clinical use, the bone screw is fixed on the bone through the round hole in the middle of the fixing part, and the buckling part is used for fixing the bent part in the marrow cavity on the bone while the bone screw is fixed. The structure is simple, the use is convenient, and the problem that the elastic intramedullary nail, the kirschner wire and the like retreat in the use process after the tail part is bent at present can be solved.

Description

Intramedullary fixation tail clip

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to intramedullary cavity internal fixation tail card.

Background

The common intramedullary cavity is internally fixed with mainly elastic intramedullary nails, kirschner wires, intramedullary nails and the like. Among them, the elastic intramedullary nail and the kirschner wire have displacement problem and sharp tail end protrusion in the using process, which is easy to irritate the surrounding soft tissues to cause complications. Therefore, it is common practice for the surgeon to bend the portion exposed outside the bone to prevent the tail portion left on the bone surface from irritating or submerging into the bone surface and becoming impossible to remove at a later date. Although bending avoids the risk of submerging into the facet, there is still a risk of withdrawal.

The first embodiment is as follows:

the utility model provides a medullary cavity internal fixation tail clamp as shown in figure 1 and figure 2, which is characterized in that comprises:

a buckling part which is arranged at the front end of the main body,

a threaded hole arranged in the buckling part;

a circular hole provided in the fixing portion;

the tail clamp is hung and held through the threaded hole, and the round hole is connected with the bone screw, so that the inner fixation of the medullary cavity is realized.

In the specific implementation process, the tail clip consists of a clamping part A1 and a fixing part A2. The buckling part A1 is in an arch bridge shape, and a threaded hole A11 is formed above the buckling part A1 and used for temporarily hanging and holding a tail card; the fixing part A2 is provided with a round hole A21 for a bone screw to pass through, the bone screw passes through the round hole A21 and is screwed into a bone, the bent intramedullary cavity can be tightly clamped to fix the tail end, and the fixation is firm and the withdrawal is prevented.

Example two:

the utility model provides a medullary cavity internal fixation tail clamp as shown in figure 3 and figure 4, which is characterized in that comprises:

a buckling part which is arranged at the front end of the main body,

a threaded hole provided in the fixing portion;
