Abstract

A needle-piercing forceps for fracture reduction and fixation belongs to a surgical instrument, in particular to a surgical tool for treating supracondylar humerus fractures in children, which can assist in reduction, accurately position Kirschner wires, reduce operation time, and be safe and reliable in operation. The needle-piercing pliers for fracture reduction and fixation of the utility model includes medical pliers. The medical pliers include a pliers handle and a pliers head. The pliers head is on the top of the pliers handle. An "L"-shaped guide is installed in the middle of the handle of the medical pliers, and the "L"-shaped guide moves forward and backward along the axial direction; a Kirschner wire catheter is installed on the pliers head, and is connected by a shaft pin. The fracture reduction and fixation needle-piercing forceps of the utility model has simple structure, scientific design and convenient use. During the treatment process, the continuous traction of the forceps can make the fixation of the broken end more stable. The needle catheter is used to determine the angle of the sagittal plane and the coronal plane, so as to improve the accuracy of Kirschner wire reset.

Description

Needle forceps for fracture reduction and fixation

technical field

The utility model belongs to a surgical instrument, in particular to a surgical tool for treating supracondylar fracture of humerus in children, which can assist reset, precisely position Kirschner wire, reduce operation time, and is safe and reliable in operation.

Background technique

Supracondylar humerus fractures in children are the most common and most frequent bone injuries in children, accounting for about 26.7% of all injuries in children. Elbow deformity and dysfunction are often caused by improper handling or overtreatment and mistakes. At present, the vast majority of supracondylar humerus fractures in children are often reduced by manipulation and internal fixation with Kirschner wires. During the treatment process, the operator controls the stability of the fracture on the one hand, and accurately positions the Kirschner wire on the other hand. Usually, the doctor’s personal experience or the C-arm fluoroscopy reset is used, which results in prolonged operation time and excessive exposure of the C-arm by the doctor.

Contents of the invention

What the utility model aims to solve is that in children's supracondylar humerus fracture surgery, the operator needs to control the stability of the fracture on the one hand, and needs to accurately position the Kirschner wire on the other hand, the operation time is prolonged, and the doctor is exposed to too much radiation on the C arm. Accurate positioning, shortening operation time, and easy reduction and needle insertion in the process of fracture treatment are children's humeral supracondylar fracture reduction and fixation needle-threading forceps.

The needle-piercing pliers for fracture reduction and fixation of the utility model includes medical pliers. The medical pliers include a pliers handle and a pliers head. The pliers head is on the top of the pliers handle. An "L"-shaped guide is installed in the middle of the handle of the medical forceps, and the "L"-shaped guide moves back and forth along the axial direction to judge the displacement of the sagittal plane; a Kirschner wire catheter is installed on the pliers head, connected by a shaft pin, Used to judge coronal plane shift.

During the treatment process, the patient's internal and external condyle of the humerus is first clamped by the head of the forceps, the sliding guide is fixed vertically to the distal end of the humerus, and the Kirschner wires are respectively implanted into the bone along the Kirschner wire catheter, and the operation is completed. During the whole treatment process, due to the fixation of the forceps, the rotation and lateral displacement are avoided, and the continuous axial traction avoids shortening and ulnar displacement, which strengthens the stability of the fracture. After stabilization, the Kirschner wire moves along the The needle catheter implantation shortens the operation time, reduces personnel operations, greatly reduces the C-arm irradiation, and improves the operation efficiency.

The needle-piercing pliers for fracture reduction and fixation of the utility model has simple structure, scientific design, and is convenient to use. During the treatment process, the continuous traction of the pliers can make the fixation of the broken end more stable. The needle catheter is used to determine the angle of the sagittal plane and the coronal plane, which improves the accuracy of Kirschner wire reduction, improves the fracture reduction of patients, and achieves better therapeutic effects.

Detailed ways

Embodiment 1: A needle-piercing pliers for fracture reduction and fixation, including medical pliers. The medical pliers include a pliers handle 1 and a pliers head 2. The pliers head 2 is on the top of the pliers handle 1. The two pliers handles 1 are connected by a pivot pin 3 and wound around When the shaft pin 3 rotates, an "L"-shaped guide 4 is installed in the middle of the handle 1 of the medical forceps, which moves back and forth along the axial direction, and is used to judge the displacement of the sagittal plane; The pin 3 is connected to judge the coronal displacement, based on the above two points, the positioning of the Kirschner wire is accurate.

During the treatment process, the patient's medial and medial condyle of the humerus is first clamped by the pliers head 2, the "L" guide is slid to fix the distal humerus vertically, and the Kirschner wires are respectively implanted into the bone along the Kirschner wire catheter 5. During the whole treatment process, due to the fixation of the forceps, the rotation and lateral displacement are avoided, and the continuous axial traction avoids shortening and ulnar displacement, and strengthens the stability of the fracture. After stabilization, the Kirschner wire is implanted along the catheter. Income, shorten the operation time, reduce personnel operations, greatly reduce the C-arm irradiation, improve the operation efficiency.
