Description

Steel wire guider for reposition of bone block

Technical Field

The invention relates to an instrument for orthopedic surgery, in particular to a steel wire guider for repositioning a displaced bone block.

Background

At present, limbs are long, most scholars advocate closed reduction intramedullary nail fixation, but to comminuted fracture, it is great that closed reduction often has bone piece and main bone separation in the art, influences fracture healing, cuts open the reduction, and it is great to local blood circulation destruction. How to approach the bone blocks to the main bone under the condition of minimal invasion, in clinical attention, currently, some researchers develop a steel wire guider which can assist in solving similar problems, but the operation is complex, the incision is large, and the guider is heavy.

In this context, we have devised improvements to this patent.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a displaced bone block reduction steel wire guider which can quickly complete the bone block reduction operation of the long bones of the limbs under minimally invasive operation.

In order to solve the technical problems, the invention provides the following technical scheme:

the utility model provides a aversion bone piece steel wire guider that resets, its includes the handle, and handle the place ahead stretches out elongated resetting means, and the resetting means front end sets up to the hollow section of thick bamboo of circular arc, and it still includes semi-circular inner skleeve, semi-circular inner skleeve and the cooperation of the hollow section of thick bamboo of circular arc, and the one end of semi-circular inner skleeve sets up the inner skleeve handle.

Preferably, the circular arc hollow cylinder is arranged into a quarter circular arc, and the radius of the circular arc is 1.5-4 cm.

Preferably, the head of the circular arc hollow cylinder is provided with 40-60 slopes.

Preferably, the handle of the semi-circular inner sleeve and a tangent of the semi-circular inner sleeve are angled at 40-90 degrees.

The steel wire guider for resetting the displaced bone block comprises a handle, wherein a slender resetting device extends out of the front of the handle, the front end of the resetting device is provided with a circular arc hollow cylinder, the guider also comprises a semicircular inner sleeve, the semicircular inner sleeve is matched with the circular arc hollow cylinder, and one end of the semicircular inner sleeve is provided with an inner sleeve handle. During the operation, cut the osculum at fracture piece level, separate soft tissue to sclerotin, the front end through the hollow section of thick bamboo of resetting means's circular arc carries out periosteum and passes, then bone piece cortex is hugged closely to circular inner skleeve, hook the bone piece, rotatory the prizing simultaneously, be close to main bone and continuously prize and dial fixed bone piece, penetrate semi-circular inner skleeve with the steel wire, through rotatory handle, screw out from the rear, draw the steel wire, take-up steel wire two to the outside, withdraw from the director simultaneously, tie the steel wire, it is close to main bone and fixed to accomplish the bone piece. The use is very convenient, the operation speed is improved, and the pain of patients is relieved.

The arc hollow cylinder of the technical scheme is a quarter arc, and the radius of the arc is 1.5-4 cm. The size can be set to be various, and the use is selected according to the operation position.

According to the technical scheme, the head of the circular arc hollow cylinder is provided with a 40-60 slope, and the slope is arranged, so that the front end can form a tip, and periosteum stripping and soft tissue pushing are facilitated.

According to the technical scheme, the handle of the semicircular inner sleeve and the tangent line of the semicircular inner sleeve form an included angle of 40-90 degrees. Therefore, the semicircular inner sleeve can rotate in the circular arc hollow barrel, rear soft tissues can be protected, and steel wire leading-out can be ensured.

The steel wire guider for resetting the displaced bone block has the following advantages:

1. when the reduction device is placed, the tip has a 40-60 slope, and can replace a periosteum stripper to push soft tissues;

2. when crossing the bone block, the bone hook can be replaced to perform bone block reduction and temporary fixation;

3. the semicircular inner sleeve can rotate for a certain angle in the circular arc hollow cylinder, so that rear soft tissues can be protected, and the steel wire can be led out;

4. the double ends of the tensioning steel wires can be realized, and the bone blocks are prevented from being separated again after the guider is withdrawn.

The technical scheme has the advantages of simple structure, convenient use and small surgical incision, can quickly complete the surgery under minimally invasive operation, and can be popularized and used in orthopedics.
