Abstract
The utility model relates to a femoral trochanteric wire introducer, which comprises a wire introducing pipe, wherein the wire introducing pipe is an arc-shaped hollow pipe, the end surface of the wire introducing pipe is an inclined surface, i.e. the end surface of the wire introducing pipe and the central line L of a handle form a sharp angle alpha, so that the end surface of the wire introducing pipe is a sharp inclined surface, and a sharp tip is formed on the end surface of the wire introducing pipe, so that the wire introducing pipe is convenient to penetrate through joint capsule tissues. The utility model has the following advantages that: a steel wire or a titanium wire is inserted into the wire introducing pipe through a through hole on the handle and exposed out of the end surface of the wire introducing pipe, and because the wire introducing pipe is the arc-shaped hollow pipe and the end surface of the wire introducing pipe is the inclined surface, the wire introducing pipe is convenient to penetrate through the joint capsule tissues. The femoral trochanteric wire introducer has a simple structure, is convenient to use, can be rapidly clung to a bone surface and penetrate through the muscles and the joint capsule tissues around a fracture and is suitable for the encircling fixation of femoral trochanteric fractures.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates to a kind of wire introducer that is applied in the peritrochanteric femoral fractures open reduction internal fixation treatment specifically.
Background technology
Fracture of femur is the commonly encountered diseases in the orthopaedics, relates to peritrochanteric femoral fractures and generally adopts guiding steel wire ring bundle bone fixation folded block in the open reduction internal fixation treatment.At fracture end a large amount of muscle and joint capsule tissue apposition are arranged, traditional steel wire circular ligate technique for fixing is by peeling off the method for muscle and joint capsule tissue, with the steel wire loop wire walk around fracture end encircle prick fixing, this method need be organized detacher with vascular forceps, periosteal elevator and joint capsule, operating difficulties, joint capsule tissue injury is bigger, and accidentally can be damaged to the nerve in the muscle.Because the shape of femoral trochanter portion uniqueness, conventional wire introducer are not suitable for using.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency a kind of femoral trochanter portion wire introducer is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of femoral trochanter portion wire introducer, comprise the steel wire guiding tube, described steel wire guiding tube is the arc hollow pipe, the end face of steel wire guiding tube is the inclined-plane, be that to form an acute angle be a for the centre line L of the end face of steel wire guiding tube and handle, thereby the end face that makes the steel wire guiding tube is sharp property inclined-plane, and steel wire guiding tube end face forms a sharp keen point, is convenient to pass the joint capsule tissue.
Above-mentioned femoral trochanter portion wire introducer, the other end of described steel wire guiding tube is provided with on the handle, and through hole is arranged on the handle, through hole and steel wire guiding tube UNICOM.
Adopt technique scheme; this utility model has following advantage: wire or titanium line are inserted in the steel wire guiding tube by the through hole on the handle; expose from the end face of steel wire guiding tube; because the steel wire guiding tube is that the end face of arc hollow pipe and steel wire guiding tube is the inclined-plane; be that to form an acute angle be a for the centre line L of the end face of steel wire guiding tube and handle; be convenient to pass the joint capsule tissue; so just avoid steel wire to enter the hip joint inboard; protect to greatest extent periosteum and and condyle tissue complete; tissue injury is little, avoids injured nerve and blood vessel, guarantees the blood supply of fracture end; relatively safety is beneficial to union of fracture.This utility model is simple in structure, and is easy to use, can be close to surface of bone rapidly and pass fracture muscle and joint capsule tissue on every side, and the ring that is fit to peritrochanteric femoral fractures is pricked fixing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
A kind of femoral trochanter portion wire introducer as depicted in figs. 1 and 2, comprise steel wire guiding tube 1, described steel wire guiding tube 1 is the arc hollow pipe, the end face 4 of steel wire guiding tube is the inclined-plane, be that angle is arranged is a for the centre line L of end face 4 and the handle of steel wire guiding tube, thereby the end face that makes the steel wire guiding tube is sharp property inclined-plane, steel wire guiding tube end face forms a sharp keen point, be convenient to pass the joint capsule tissue, the other end at the steel wire guiding tube is provided with on the handle 2, through hole 3 is arranged on the handle 2, and through hole 3 and steel wire guiding tube UNICOM add lever operated convenient.
Work process of the present utility model is as follows: behind the conventional open reduction internal fixation with the reduction of the fracture temporary fixed after, steel wire 5 lines or titanium line are inserted in the steel wire guiding tube 4 by the through hole on the handle 3, steel wire guiding tube 1 is pasted surface of bone to be walked around, when the end face 4 of steel wire guiding tube 1 exposes, take out the steel wire 5 in the steel wire guiding tube 1, again with steel wire guiding tube 1 from former around withdrawing from, tighten up steel wire and promptly finish bootup process.Because the inclined-plane of the end face of whole bootup process steel wire guiding tube is inside, avoids steel wire to enter the hip joint inboard, and is more safe and reliable in clinical use.
Claims (2)
1. a femoral trochanter portion wire introducer comprises steel wire guiding tube (1), it is characterized in that: described steel wire guiding tube (1) is the arc hollow pipe, and the end face of steel wire guiding tube (4) is the inclined-plane.
2. femoral trochanter according to claim 1 portion wire introducer, it is characterized in that: the other end of described steel wire guiding tube is provided with on the handle (2), and through hole (3) is arranged on the handle (2), through hole (3) and steel wire guiding tube UNICOM.
