Description

Positioning device for vertebroplasty

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a positioning device for vertebroplasty.

Background

Vertebroplasty refers to a minimally invasive surgical mode for compression fracture of an osteoporosis vertebral body of an elderly person, and is a technology of penetrating into a vertebral pedicle through skin by using a specific puncture working cannula, further entering a fractured pathological vertebral body, and then injecting bone cement (commonly used as polymethyl acrylate) into the pathological vertebral body to strengthen the vertebral body.

When a physician is treating a patient using vertebroplasty, the first step is also important to mark the outside of the skin, marking the body surface projection of the pedicle. To achieve this, a metal locating plate is placed outside the skin of the back lesion vertebral body, then a mobile C-shaped X-ray machine is used for fluoroscopy, the position of the locating device on the body surface is judged, and then a medical marker pen is used for marking the pedicle position according to X-ray films. A percutaneous vertebroplasty positioning device disclosed in chinese utility model with publication number CN205054417U is a conventional positioning metal plate. However, the conventional method has the following problems: the metal locating plate has poor fitting degree with the back of the human body, and marking errors are easy to generate; the metal positioning plate has limited size, and sometimes the mark point and the target position have larger difference and cannot be marked; the metal locating plate is easy to shield, and operation and use are affected.

The object of the present utility model is to overcome the above-mentioned drawbacks of the prior art by providing a positioning device for vertebroplasty.

The aim of the utility model can be achieved by the following technical scheme:

a positioning device for vertebroplasty comprising a metal unit and a patch, the metal unit being disposed on a non-adhesive facing of the patch.

Further, the metal units are metal points.

Further, the metal unit is a metal ring, and a patch area surrounded by the metal ring is provided with a through hole matched with the metal ring in shape.

Further, the metal ring is a triangular ring, a circular ring, a rectangular ring, a diamond ring or a polygonal ring.

Further, the metal unit is disposed at a geometric center of the patch.

Further, the adhesive surface of the patch is a gel layer.

Compared with the prior art, the utility model has the following beneficial effects:

1. the utility model has convenient use, can be tightly adhered to the back during positioning and placement, can randomly adjust the combined position, is particularly suitable for patients with scoliosis or back deformity, and ensures that the positioning is clear and accurate.

2. The metal unit adopts an annular structure, and the patch in the annular shape is provided with a through hole, so that a doctor can directly mark the through hole in the metal unit, and the marking precision is improved.

3. The metal rings can be in different shapes and used in combination, so that doctors can conveniently carry out combination comparison of the X-ray film and the device object; meanwhile, the shape can be drawn along the inner side of the metal ring by using a marker pen during marking, and the operation is convenient.

4. The adhesive surface of the patch is a gel layer, so that the patch can be conveniently attached to a human body and can be repeatedly used.

5. The whole material can be a cleaning material and is disposable, so that repeated use among patients is avoided, and the risk of cross contamination is increased.

Detailed Description

The utility model will now be described in detail with reference to the drawings and specific examples. The present embodiment is implemented on the premise of the technical scheme of the present utility model, and a detailed implementation manner and a specific operation process are given, but the protection scope of the present utility model is not limited to the following examples.

Example 1

As shown in fig. 1, the present embodiment provides a positioning device for vertebroplasty, comprising a metal unit 1 and a patch 2. The patch 2 is a round piece with the diameter of about 6cm, one surface is a sticky surface, and the other surface is a smooth surface; the adhesive surface can adopt a gel layer to be convenient for adhering to the skin of a human body. The metal unit 1 is disposed on the light surface of the patch 2. The metal unit 1 is specifically a metal ring, and the shape of the metal ring is not limited, and a triangular ring, a circular ring, or a rectangular ring can be generally used. The circular ring is shown in fig. 1, and the triangular ring and the rectangular ring are shown in fig. 2 and 3, respectively. The diameter of the circular ring is 1-2 cm, the length of the rectangular ring is 1-2 cm, and the side length of the triangular ring is 1-2 cm. The metal unit 1 is arranged at the center of the patch 2, a through hole 21 matched with the shape of the metal ring is arranged at the patch 2 surrounded by the metal ring, and the skin is directly exposed at the through hole 21.

As shown in fig. 4, the use procedure of the present embodiment is as follows: the doctor directly laminates a plurality of positioner at patient's back, and the shape of the ring is different among the positioner that selects for use, is convenient for distinguish different positions. And then using a movable C-shaped X-ray machine to carry out perspective, judging the position of the positioning device on the body surface, then using a medical marking pen to draw marks on the back of the human body along the inner edge in each metal ring, taking down a plurality of positioning devices, and finally combining the positions of the metal rings and the positions of the pedicles in the X-ray film, and finally positioning and marking the positions of the pedicles on the back of the human body according to the drawn marks.

In summary, the present embodiment has the following advantages: the use is convenient; the adhesive has the adhesive function, is tightly adhered to the skin and is not easy to shift; only a middle point of each positioning device is provided with metal, and shielding can not be formed in the X-ray film; the center is provided with a hollow space, so that the label can be directly marked without tearing off the patch; the plurality of positioning devices adopt different metal unit shapes, and can intuitively distinguish the positioned parts on the X-ray film; for patients with scoliosis and kyphosis deformity or larger physiological angles of the spine, the perspective error can be obviously reduced.
