Description

Kirschner wire placement guiding positioner

Technical Field

The utility model belongs to orthopedics medical instrument field especially relates to a guiding orientation ware is put into to ke shi needle.

Background

Fracture of limbs is the most common injury in trauma orthopedics, comminuted fracture of tibial plateau is the most serious injury in lower limbs, and the activity and the stable function of knee joints can be influenced by serious patients. The comminuted fracture of the tibial plateau generally needs to be treated by operation, and the fracture needs to be dissected and reset, and is strongly fixed internally and has early function exercise.

The comminuted fracture of the tibial plateau can show a plurality of fracture blocks, after the soft tissues at the fracture part are removed, the affected limb is pulled, the larger fracture block is generally reset firstly, the kirschner wire is temporarily fixed, then the fracture is reset integrally, a plurality of kirschner wires are fixed by the bamboo raft technology, the reset condition is checked under fluoroscopy, namely the integral force line is kept, and the joint surface is kept flat. The nerves of the blood vessels at the back and the outside of the knee are rich, and important tissues are easily damaged in the process of inserting the Kirschner wire. Usually, the kirschner wires with the diameter of 2.0 or below are selected to be used for temporarily fixing a fracture block, the kirschner wires are soft, and sometimes, the kirschner wires bend when meeting hard bone, so that errors occur at a needle outlet point, the repeated needle insertion and needle discharge affect the operation reduction effect, the fluoroscopy frequency is increased, the operation time is prolonged, and unnecessary tissue injury is also brought. Therefore, how to quickly and accurately place the kirschner pin in the operation is very important.

Disclosure of Invention

The utility model aims at: the guiding locator for placing the kirschner wire is designed, and the guiding locator is used for quickly and accurately fixing a fracture block, shortening the operation time, improving the operation effect and reducing the pain of a patient.

The technical solution of the utility model is that: the Kirschner wire imbedding guide positioner comprises a hollow sleeve, a semi-arc tube and an arc-shaped hook, wherein a tip hook is arranged at the tail end of an arc rod and is the arc-shaped hook, the sleeve is sleeved on the outer wall of the hollow sleeve, one end of the semi-arc tube is installed on the sleeve through a fixing screw, the arc-shaped hook is installed at the other end of the semi-arc tube through an adjusting screw and an adjusting elongated slot, the semi-arc tube and the arc-shaped hook form a semi-arc together, and the tip hook of the arc-shaped hook and the hollow sleeve are in the.

Furthermore, a handle is arranged on the half arc pipe.

Furthermore, the head end of the hollow sleeve is a smooth tip.

Furthermore, a handle is arranged at the tail end of the hollow sleeve.

The utility model has the advantages that: 1. the head end of the hollow sleeve is a smooth tip, so that the hollow sleeve is favorable for penetrating soft tissues and fixing bone surfaces and is not easy to slide; 2. the tail end of the arched rod is provided with a sharp hook which is an arched hook, is favorable for fixation on the bone surface and is not easy to slide; 3. the semi-arc pipe and the arc hook form a semi-arc together, so that the tip hook of the arc hook and the hollow sleeve are on the same diameter, and the drill bit is guaranteed to be fixed in a point-to-point guiding mode relative to the tip hook of the arc hook when the drill bit drills into the cortex lycii from the hollow sleeve on one side to the other side.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure: the device comprises a hollow sleeve 1, a sleeve 2, a semi-arc tube 3, an arch hook 4, a sharp hook 5, a fixing screw 6, an adjusting screw 7, a handle 8, a handle 9 and an adjusting long groove 10.

Detailed Description

As shown in figure 1, the Kirschner wire imbedding guiding positioner comprises a hollow sleeve 1, a sleeve 2, a semi-arc tube 3 and an arch hook 4, wherein a sharp hook 5 arranged at the tail end of an arch rod is the arch hook 4, the sleeve 2 is sleeved on the outer wall of the hollow sleeve 1, one end of the semi-arc tube 3 is installed on the sleeve 2 through a fixing screw 6, the arch hook 4 is installed at the other end of the semi-arc tube 3 through an adjusting screw 7 and an adjusting long groove 10, the semi-arc tube 3 and the arch hook 4 form a semi-arc together, and the sharp hook 5 of the arch hook and the hollow sleeve 1 are on the same diameter.

Furthermore, a handle 8 is arranged on the half-arc pipe 3.

Furthermore, the head end of the hollow sleeve 1 is a smooth tip.

Further, a handle 9 is provided at the end of the hollow sleeve 1.

When the bone fracture guiding device is used, the handle 8 and the handle 9 are held by hands, the head end of the hollow sleeve 1 of the guiding positioner is aligned to one side of a fracture block, the adjusting screw 7 is adjusted again, the tip hook of the arch-shaped hook 4 is aligned to the other side of the fracture block, and when a drill bit drills into bone cortex from the hollow sleeve 1 on one side to reach the other side, the drill bit is right aligned to the tip hook of the arch-shaped hook 4, so that point-to-point guiding and fixing are achieved.
