According to the utility model discloses a prevent displacement cerclage and tie area easy to carry out, can prevent that cerclage and tie area from producing the displacement in the internal fixation operation of fracture or postoperative to reach better postoperative effect.

Description

Displacement-preventing cerclage binding belt

Technical Field

The utility model relates to the field of medical equipment, more specifically relates to a can prevent displacement cerclage and tie that cerclage and tie takes place aversion phenomenon during fracture internal fixation treatment period.

Background

In modern orthopedic medical treatment, in the internal fixation treatment of oblique fracture of human body, a cerclage binding belt is often applied for internal fixation so as to obtain good medical effect.

However, the cerclage binding band currently used only has a tightening action of a centripetal force when binding an oblique fracture site. Because each part of the human skeleton is not similar to a standard cylinder, the outer diameter is not very round, and some parts bound by the cerclage present cones of different degrees. Therefore, during or after the operation of fixing the cerclage strap, axial displacement of the cerclage strap to a different extent in the bone may occur, and the internal fixing effect may be affected.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, the present invention provides a displacement-preventing cerclage binding band which can prevent displacement of the cerclage binding band during internal fixation treatment of fracture.

According to the utility model discloses, a prevent displacement cerclage and tie area includes: a locking member having a locker, and an elongated hole formed at one end of the locking member; a binding band, one end of which passes through the elongated hole and is folded back such that a part of the binding band is overlapped, and the overlapped part is formed with a through hole, and the other end of which passes through the locker around the bone and is locked; and an anti-displacement screw having a screw cap at a tip thereof, penetrating the through hole and being screwed into a threaded hole formed in the bone, and then being tightened to compress the binding strip between the bone and a lower end surface of the screw cap, thereby preventing the binding strip from being moved.

Alternatively, the portion of the binding strip where the through-hole is formed may have a larger width.

According to an exemplary embodiment, the buckle may further include a fastener, and the other end of the binding band may be formed with a fastening hole such that when the other end passes through the buckle, the fastening hole is located at a position corresponding to the fastener so that the fastener passes through the fastening hole to fasten the binding band.

Drawings

The above and other aspects and features of the present invention will become apparent from the following description of the embodiments, taken in conjunction with the accompanying drawings, in which:

fig. 1 is a front view of an anti-displacement cerclage strap according to one embodiment of the present invention;

fig. 2 is a side view of an anti-displacement cerclage strap according to the one embodiment of the present invention;

FIG. 3 is a partial schematic view of the anti-displacement cerclage strap according to the present invention being cerclaged to the bone during internal fixation treatment of the fracture; and

fig. 4 is a perspective view of the displacement prevention cerclage strap according to the present invention being cerclaged to the bone during the internal fixation treatment of the fracture.

Detailed Description

Illustrative, non-limiting embodiments of the present invention are described in detail below with reference to the accompanying drawings, further illustrating the displacement resistant cerclage strap according to the present invention.

The displacement prevention cerclage binding band according to the present invention may include a locking part 1, a binding band 2, and a displacement prevention screw 3, as shown in fig. 1 and 2. The locking part 1 has a shackle 10, and one end of the locking part 1 is formed with an elongated hole 11. One end of the binding band 2 passes through the elongated hole 11 and is folded back so that a part of the binding band 2 is overlapped, and the overlapped part is formed with a through hole 20. It is preferable that the portion of the binding band 2 where the through-hole 20 is formed has a larger width than other portions (as shown in fig. 1) in order to secure the tensile strength of the binding band. The other end of the binding strap 2 is passed through the locker 10 around the bone and locked. The anti-displacement screw 3 has a screw cap 30 at the top end thereof, which passes through the through-hole 20 and is screwed into a threaded hole formed on the bone during the internal fixation treatment of the fracture (as shown in fig. 3), and then the anti-displacement screw 3 is tightened to compress the binding strip 2 between the bone and the lower end surface of the screw cap 30, thereby preventing the binding strip from moving. For better compression of the binding strip, the lower end face of the screw cap 30 is flat. According to the utility model discloses a prevent displacement cerclage and tie area easy to carry out, can prevent that cerclage and tie area from producing the displacement in the internal fixation operation of fracture or postoperative to reach better postoperative effect.

According to an exemplary embodiment of the present invention, the latch 10 may include a fastener 12. The other end of the binding band 2 is formed with a fastening hole 21 such that the fastening hole 21 is located at a position corresponding to the fastening member 12 when the other end passes through the buckle 10, so that the fastening member 12 passes through the fastening hole 21 to fasten the binding band.

Although exemplary embodiments of the present invention have been described, it will be apparent to those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
