Description

Yellow ligament curet for UBE mirror

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a yellow ligament curet used under a UBE mirror.

Background

UBE (unilateral biportal endoscopy) is a single-sided double-channel endoscopic spine surgery, is an emerging minimally invasive technology, has definite curative effect on treating spine diseases, is widely applied to minimally invasive treatment of lumbar degenerative diseases at present, can also be applied to cervical vertebra and thoracic vertebra operations, and is mainly used for removing yellow ligament and reducing pressure in treatment of lumbar spinal stenosis.

The removal of the ligamentum flavum is time-consuming and labor-consuming, and when the ligamentum flavum is resected, conventional surgical instruments such as nucleus pulposus forceps, curettage forceps, gun forceps and the like are low in efficiency, particularly, the adhesion points of the ligamentum flavum are treated, the opposite-side ligamentum flavum can be treated through the over-the-top technology by the UEB technology, the origin points of the ligamentum flavum and the adhesion points of the inner edges of the joints are treated, and the problems of difficult treatment, low efficiency and easy damage to nerves and dura mater are caused.

Disclosure of Invention

The utility model provides a ligamentum flavum curet used under a UBE mirror, which solves the technical problems of low efficiency and low safety of processing ligamentum flavum.

In order to solve the technical problems, the yellow ligament curet used under the UBE mirror comprises a handle, wherein a metal rod is fixedly arranged at the bottom end of the handle, a curet head is fixedly arranged at the bottom end of the metal rod, the curet head comprises a curet spoon part and a shovel blade, the side face of the curet spoon part is fixedly connected with the bottom end of the metal rod, and the shovel blade is fixedly arranged on the side face of the curet spoon part far away from the metal rod.

Preferably, the periphery of the curette spoon part is convex and is spoon-shaped, and the shovel blade is provided with a blade.

Preferably, the central axis of the metal rod is parallel to the plane of the surface of the curette spoon part, the plane of the top surface of the shovel blade is parallel to the plane of the surface of the curette spoon part, and the side surface of the shovel blade is an angle blade surface.

Preferably, the included angle between the central axis of the metal rod and the plane of the surface of the spoon part of the curet is an angle, the top of the shovel blade is provided with a hook-shaped protrusion, and the side surface of the shovel blade is an angle blade surface.

Compared with the related art, the yellow ligament curet for use under the UBE mirror has the following beneficial effects:

the utility model provides a yellow ligament curet used under a UBE mirror, wherein the head end of the yellow ligament curet is a flat scraper knife which can be used for shoveling forward and downward, separating attachment points, the curet is arranged on two sides, the separation of the attachment points and the scraping of the yellow ligament are carried out by rotating, and the separation of the yellow ligament and the separation of bone are carried out by combining the downward shoveling separation and the left-right rotating separation scraping. The flat spade-shaped anterior head separates the bone-surface attachment points.

fig. 3 is a schematic diagram of a second exemplary curette structure according to the present utility model.

Reference numerals in the drawings: 1. a handle; 2. a metal rod; 3. a curet head; 31. a curette spoon part; 32. a shovel blade.

Detailed Description

1-2, the utility model comprises a handle 1, wherein a metal rod 2 is fixedly arranged at the bottom end of the handle 1, a curet head 3 is fixedly arranged at the bottom end of the metal rod 2, the curet head 3 comprises a curet spoon part 31 and a shovel blade 32, the side surface of the curet spoon part 31 is fixedly connected with the bottom end of the metal rod 2, the shovel blade 32 is fixedly arranged at the side surface of the curet spoon part 31 far away from the metal rod 2, the periphery of the curet spoon part 31 is convex and takes a bowl shape, the shovel blade 32 is provided with a blade, the central axis of the metal rod 2 is parallel to the plane of the surface of the curet spoon part 31, the plane of the top surface of the shovel blade 32 is parallel to the plane of the surface of the curet spoon part 31, and the side surface of the shovel blade 32 is a 45-degree knife surface;

in this embodiment, the curette is used for treating the attachment point separation of the collateral ligamentum flavum and the ventral lamina, the bone knife surface with the shovel shape at the front end is inserted between the ligamentum flavum and the lamina for separation, the hardness is better than that of nerve stripper, the curette is thinner than the conventional curette, the efficiency for treating the attachment point of the ligamentum flavum and the lamina is higher, and the efficiency can be improved by expanding and separating by utilizing the left and right rotation of the curette at the left and right sides.

In the second embodiment, as shown in fig. 3, an included angle between a central axis of the metal rod 2 and a plane on which a surface of the curette spoon 31 is located is 135 °, a hook-shaped protrusion is provided on the top of the shovel blade 32, and a side surface of the shovel blade 32 is a 90 ° blade surface;

in this embodiment, the curette is used for treating adhesion of the ligamentum flavum on the upper edge of the lamina on the same side and on the opposite side, the hooked protrusion at the front end is beneficial to separating the superficial ligamentum flavum with loose and thick upper edge of the lamina from the bone surface, the bending angle is beneficial to separating the ligamentum flavum on the same side from the adhesion point on the inner edge of the superior articular process, and the hooked protrusion at the top end is beneficial to being inserted between the ligamentum flavum and the superior articular process.

Working principle: the flat blade 32 at the head end can be shoveled forward and downward to separate the attachment points, the spoon-shaped curettes at the two sides are used for separating the attachment points and scraping the ligamentum flavum by rotating, and the attachment points and bones of the ligamentum flavum are separated by combining downward shoveling separation and left-right rotating separation scraping.
