Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a surgical positioning patch. Background Technology

[0002] Surgical dressings are commonly used during surgery to further reduce the risk of surgical infection and are increasingly favored by surgeons. Thoracolumbar spine surgery is one of the common surgical procedures in spinal orthopedics. Before surgery, C-arm fluoroscopy is often used to locate the vertebral body and identify the vertebral segment to be operated on. In minimally invasive percutaneous pedicle screw fixation surgery, pedicle positioning is required before surgery. Spinal surgeons often use one or more Kirschner wires on the body surface and use C-arm fluoroscopy for fluoroscopy, or choose the surgical incision based on clinical experience. If the Kirschner wire is not placed correctly before surgery, the position of the Kirschner wire often needs to be adjusted several times, which increases the anesthesia time and the number of fluoroscopy sessions, increases the radiation damage to the doctor and patient's C-arm, and prolongs the operation time.

[0003] There is an urgent need for a surgical positioning patch for the thoracic and lumbar spine that can improve the accuracy of vertebral positioning. Utility Model Content

[0004] This invention addresses the problems and shortcomings of existing technologies by providing a surgical positioning patch for thoracic and lumbar spine procedures.

Attached Figure Description

[0033] Figure 1 This is a schematic diagram of a specific embodiment 1 of the present utility model;

[0034] Figure 2 This is an exploded view of specific embodiment 1 of the present utility model. Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] like Figure 1 as well as Figure 2As shown in Specific Embodiment 1, a surgical positioning patch for thoracolumbar spine includes a patch base, which includes a positioning patch assembly arranged at the top and bottom and a bottom support film 4. An adhesive layer for attaching to the body surface is provided on the lower side of the bottom support film 4. The positioning patch assembly is adhered to the bottom support film 4. The positioning patch assembly includes an upper transparent film 2, a middle positioning interlayer 1, and a lower transparent film 3 arranged sequentially from top to bottom. The middle positioning interlayer 1 includes a metal positioning mesh structure 12 for positioning the pedicles, located at the center of the positioning patch assembly in the left-right direction and extending from front to back. The middle positioning interlayer also includes at least five transverse metal positioning wires 17 arranged from front to back, extending from left to right to the metal positioning mesh structure 12 with the left-right direction as the length direction. The middle positioning interlayer also includes positioning markers 18, which correspond one-to-one with the transverse metal positioning wires 17 and are arranged adjacent to each other. This invention optimizes the structure of the positioning film to facilitate vertebral positioning, and uses positioning markers for rapid positioning. After positioning with the positioning film assembly, the assembly is directly peeled off, leaving the bottom supporting film 4 as a sterile film for the surgical area.

[0037] The upper transparent film 2 and the lower transparent film 3 are bonded together. A metal positioning mesh structure is sandwiched between the upper transparent film 2 and the lower transparent film 3. The adhesive used to bond the upper transparent film 2 and the lower transparent film 3 is embedded in the mesh of the metal positioning mesh structure.

[0038] The upper transparent film 2, the lower transparent film 3, and the bottom supporting film 4 are all polyethylene films.

[0039] The right end of the horizontal metal positioning wire 17 extends beyond the metal positioning mesh structure 12, but the extension length is no more than 10cm. This avoids visual interference when viewed from the side.

[0040] The length of a single mesh opening in the metal positioning mesh structure 12 is 1 cm. The number of grids in the left-right direction of the metal positioning mesh structure 12 is at least 5.

[0041] The spacing between adjacent transverse metal positioning wires 17 is 4cm-15cm. Preferably, the spacing between adjacent transverse metal positioning wires 17 is 10cm-15cm.

[0042] The positioning marker 18 can be a letter or number. The positioning marker is located on the left side of the positioning membrane assembly.

[0043] The positioning marker 18 is made of copper; the metal positioning mesh structure 12 is made of copper wire; and the horizontal metal positioning wire 17 is made of copper wire.

[0044] The positioning film assembly has easily peelable areas 11 at both its front and rear ends, which abut against the bottom support film 4. An adhesive area for adhering to the bottom support film 4 is provided between the easily peelable areas 11 at the front and rear ends of the positioning film assembly. This facilitates the peeling of the positioning film assembly. The cross-sectional area of ​​the adhesive area is no more than 30% of the cross-sectional area of ​​the positioning film assembly; the cross-sectional area of ​​the adhesive layer is greater than 70% of the cross-sectional area of ​​the bottom support film 4. This facilitates peeling and removal.

[0045] The metal positioning mesh structure of the positioning membrane assembly is located in the middle region of the vertical projection of the easily peelable areas at the front and rear ends. The transverse metal positioning wires of the positioning membrane assembly are located in the middle region of the vertical projection of the easily peelable areas at the front and rear ends. The transverse metal positioning wires of the positioning membrane assembly are located in the front region adjacent to the positioning membrane assembly.

[0046] The bottom carrier film 4 is connected to the release paper layer via an adhesive layer. A printed layer matching the vertical projection of the intermediate positioning interlayer is provided on the bottom carrier film. This facilitates positioning after the positioning film assembly is removed. Positioning can also be achieved using methods such as pinhole punching.

[0047] The length of the patch substrate in the left-right direction matches the length of the patient's left and right midaxillary lines along the body surface. The left side of the patch substrate is adjacent to the patient's left midaxillary line. The right side of the patch substrate is adjacent to the patient's right midaxillary line.

[0048] See Figure 1 When in use, this device uses a metal positioning mesh structure to locate the positions of vertebral body 13, pedicle 14, and twelfth rib 15 under C-arm projection, and uses transverse metal positioning wires 17 to locate the positions of the posterior superior iliac spine 16 and twelfth rib 15 under C-arm projection. This facilitates accurate positioning during surgery. Figure 1 The image shows a schematic diagram of a local location under C-arm projection.

[0049] In use, after successfully anesthetizing the patient, perform routine disinfection and draping. Once the skin is dry, tear off the release paper layer and lay the bottom support film flat on the body surface. Place the metal positioning mesh structure at the midline of the spine to facilitate the positioning of the pedicles and vertebral bodies of the thoracic and lumbar vertebrae. Place the positioning marker at the extension line of the midaxillary line to facilitate C-arm lateral positioning of the lumbar vertebrae. After laying everything flat, drape it on top and use fluoroscopy to locate the vertebral bodies.

[0050] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
