Abstract

The utility model discloses a metal spicule for orthopedics, in particular to a metal spicule with a flat needle head. The metal spicule comprises a tail part, a rod part and a head part which are of an integral structure, and is structurally characterized in that the tail part is provided with a thread part which can rotate around the tail part, the outer surface of the thread part is provided with external threads, and the top surface of the thread part is recessed inwards to form a hexagonal slotted hole; the head part is a flat needle head; the head is bent to one side. The utility model has the advantages of simple operation, convenient insertion, stable fixation and no damage to soft tissues.

Description

Metal spicule with flat needle head

Technical Field

The utility model relates to a metal spicule for orthopedics, in particular to a metal spicule with a flat needle head.

Background

The metal spicules are partially implanted into a human body for traction when the fracture is reduced or play a role in internal fixation when the bone surgery is performed. The shank of the existing metal spicule is provided with threads at the position close to the head, when an operation is performed, a bone drill is firstly used for drilling a hole on the bone to form a working channel, then a screw tap matched with the spicule is used for tapping, and finally the metal spicule is installed. When the metal spicule is installed, the spicule needs to be screwed into the bone flesh in a rotating mode, and displacement and soft tissue injury are easily caused.

Disclosure of Invention

The technical problem to be solved by the utility model is to provide a metal spicule of flat syringe needle that easy operation, be convenient for insert, fixed stable, do not harm the soft tissue.

The utility model provides a technical scheme that above-mentioned problem adopted is: the metal spicule comprises a tail part, a rod part and a head part which are of an integral structure, and is structurally characterized in that the tail part is provided with a thread part which can rotate around the tail part, the outer surface of the thread part is provided with external threads, and the top surface of the thread part is recessed inwards to form a hexagonal slotted hole; the head is a flat needle.

The head of the utility model is bent towards one side.

Compared with the prior art, the utility model, following beneficial effect has: 1. the head of the metal spicule is a flat needle head and is bent towards one side, and when the metal spicule is used, only a small opening is formed in the skin, the bent needle head can enter the bone along the opening at a small angle, so that the injury to a patient is reduced; 2. the tail of the metal spicule is provided with a threaded part capable of rotating around the tail, and the metal spicule can be fixed under the condition that the tail, the rod part and the head part are not rotated by matching with an inner hexagonal wrench, so that the metal spicule cannot be displaced during the healing of the fracture, and soft tissues cannot be stimulated.

Detailed Description

Referring to fig. 1-4, the present embodiment includes a tail portion 1, a rod portion 2 and a head portion 3, which are integrally formed, the tail portion 1 is provided with a threaded portion 4 capable of rotating around the tail portion, the outer surface of the threaded portion 4 is provided with external threads, and the top surface of the threaded portion is recessed to form a hexagonal slot 5; the head 3 is a flat needle, and the head 3 is bent to one side.

The length of this embodiment is between 60-400mm, and can be used for long cortical bone and cancellous bone near the joint. When the metal bone needle is used, a small opening is formed in the skin, the bent head 3 enters bone flesh along the opening at a small angle, the metal bone needle is inserted into the bone flesh, the threaded part 4 is rotated by an inner hexagonal wrench matched with the hexagonal slotted hole 5, and the metal bone needle is fixed under the condition that the tail part 1, the rod part 2 and the head part 3 are not rotated.
