Description

Under-mirror fusion full-visual reamer

Technical Field

The utility model relates to the technical field of medical equipment, further be a reamer, visual reamer for minimal access surgery.

Background

With the rapid development of minimally invasive surgery, spinal minimally invasive techniques represented by spinal endoscopy have been widely applied clinically, and satisfactory effects have been achieved. The spinal endoscope technology is a minimally invasive technology for developing earlier spinal surgery, has smaller damage to paraspinal muscles compared with the traditional open surgery, can furthest reserve a complete spinal structure, maintains the stability of a post-operation spinal column, and has the advantages of small wound, less bleeding, quick recovery, less complications, exact curative effect and the like.

Intervertebral fusion is a common technique used clinically to treat the spine. Lumbar fusion methods are various, but treatment of intervertebral cartilage endplates during endoscopic fusion cannot achieve visualization.

Traditional under-lens fusion puts into the reamer under X-ray perspective, handles the cartilage endplate under the blind vision, and its processing range can not reach controllable, but relies on clinical experience, promptly: after the reamer is twisted, the reamer is pulled out, then the endoscope is placed in, the processing condition of the end plate is observed, the endoscope is pulled out again when the processing cannot be carried out, the reamer is placed through X-rays, the actions are repeated repeatedly, and the processing is carried out under the blind vision by virtue of clinical experience. The drawbacks of this are: high requirements on clinical experience of doctors, long time, poor end plate treatment and influence on fusion curative effect.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fuse full visual reamer under mirror, it can increase the nature directly perceived and the accuracy of operation, and effective control improves the operation quality.

The utility model aims at realizing through the following scheme:

the utility model provides a fuse full visual reamer under mirror, includes hinge bar, handle, reamer, and the hinge bar rear portion sets up the handle, and the hinge bar front end sets up reamer, its characterized in that: the hinge rod is of a hollow structure, a lead is arranged in the hinge rod, the rear end of the lead is connected with the endoscope or the display, and the front end and the rear end of the lead are connected with the endoscope.

The utility model aims at further realizing the following scheme of accessible:

the reamer is of a U-shaped structure, and two sides of the reamer are through.

The 4 edges of the reamer are cutting edges.

The cutting edge is a plain edge or a sawtooth.

The utility model has the advantages that: the full visual reamer is hollow, an endoscope is placed through the inner diameter of the reamer, and the cartilage end plate is processed under full visual guidance, so that the full visual reamer has the advantages that: 1. avoiding X-ray fluoroscopy; 2. the range of cartilage endplate treatment under direct vision is controllable; 3. the treatment speed is high under direct vision, and iatrogenic injury is avoided; 4. the requirements on the clinical experience of the doctor are relatively low. The utility model discloses simple structure increases the intuition and the accuracy of operation, convenient operation, and the operation is of high quality to patient's misery is few, and is recovered soon.

In order to make the technical field of the present invention better understand the scheme of the present invention and make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be described in further detail with reference to the accompanying drawings and examples.

Drawings

Fig. 1 is a schematic structural view of the present invention, and fig. 2 is a schematic structural view of the direction a in fig. 1.

In the figure: 1 is a lead, 2 is a handle, 3 is a hinged rod, 4 is a reamer, and 5 is an endoscope.

Detailed Description

As shown in fig. 1 and 2, the under-mirror fusion full-visible reamer comprises a hinge rod 3, a handle 2 and a reamer 4, wherein the handle 2 is arranged at the rear part of the hinge rod 3 and is used for operation; a reamer 4 is arranged at the front end of the hinge rod 3, the reamer 4 is of a U-shaped structure, and two sides of the reamer 4 are through (see fig. 2); the rod 3 is tubular, the hinge rod 3 is hollow, a lead 1 is arranged in the hollow structure, the rear end of the lead 1 is connected with the endoscope (or display), and the front end of the lead 1 is connected with the endoscope 5.

The 4 edges of the reamer 4 are cutting edges which can be smooth edges, and at least 1 cutting edge can be provided with sawteeth.

When setting up 2 cutting edges and having the sawtooth, can have two kinds of situations: one of two adjacent blades is a smooth blade, and the other blade is provided with a sawtooth; and secondly, two adjacent cutting edges are both smooth edges or both have sawteeth.

The total length of the hinge rod 3 and the reamer 4 is 15-16 cm, the outer diameter of the hinge rod 3 is 10-14 cm, and one specification can be manufactured at intervals of 1 mm; the internal and external diameters of the hinge rod 3 are 6.4-7.0 cm, two specifications are generally adopted, the length of the reamer 4 is 2.8-3.2 cm, and the length of the reamer 4 is 3 cm.

During the use, will the utility model discloses in arranging the cover in, observe through intervertebral foramen mirror, under the guide of endoscope, the intervertebral space cartilage endplate that needs to handle when exploring the fusion is observed through the reamer one side, and the one side is handled, until complete clean up.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
