Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a 3D printed surgical template fixing film for the body surface. Background Technology

[0002] In the field of surgery, surgeries on the body surface (such as skin tumor resection, plastic surgery, and wound repair surgery) place extremely high demands on the accuracy of lesion localization and surgical path planning. Surgical templates, as a crucial auxiliary tool, are typically customized in advance based on the patient's CT / MRI image data. They can precisely mark the surgical incision location, lesion resection boundaries, or implant placement paths. Their core function is to transform the pre-planned three-dimensional spatial coordinates into visible surface localization markers during surgery, thereby significantly improving the accuracy and repeatability of surgical procedures.

[0003] Currently, traditional methods such as adhesive tape are commonly used to fix surgical templates on the body surface. However, this method has many shortcomings. For example, the adhesiveness and fit of traditional tape may not adapt well to the complex curves of the human body surface, easily leading to insecure fixation and causing the surgical template to shift during surgery, affecting the surgical outcome. Furthermore, traditional tape has poor breathability, and prolonged use can easily cause discomfort such as allergies and redness in patients. In addition, traditional fixation methods are cumbersome to operate, requiring medical staff to spend considerable time adjusting and securing the template. Therefore, there is an urgent need for a surgical template fixation film that can solve the above problems. Utility Model Content

[0007] A further improvement of this utility model is that the main body layer is made using 3D printing technology, and the material of the main body layer is a medical polymer material.

[0008] A further improvement of this utility model is that the adhesive layer is made of medical pressure-sensitive adhesive, and the edge of the adhesive layer is provided with an anti-rolling structure, which is an arc-shaped edge extending outward from the adhesive layer.

[0009] A further improvement of the present invention is that the positioning structure includes multiple protrusions, which are evenly distributed on the upper surface of the main body layer, and the lower surface of the surgical template is provided with grooves that cooperate with the protrusions.

[0021] In this embodiment, a suitable main body layer 1 is fabricated using 3D printing technology based on the specific shape of the patient's body surface. An adhesive layer 2 is then attached to the underside of the main body layer 1 using an adhesive. A fixing film is then placed on the area of ​​the patient's body surface where surgery will be performed, and the medical pressure-sensitive adhesive of the adhesive layer 2 is used to fix it to the patient's body surface. During the surgery, the main body layer 1 fits tightly against the patient's body surface, the positioning structure 3 ensures the stability of the surgical template 5, and the ventilation holes 4 ensure skin breathability. After the surgery, the fixing film can be gently peeled off. In use, the surgical template 5 is placed on the main body layer 1, aligning the groove 51 with the protrusion 31, and gently pressed to achieve proper fixation. This positioning method is simple and quick, ensuring that the surgical template 5 is accurately positioned in the required location during the surgery without displacement.

[0022] Example 2

[0023] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, an adhesive layer 2 is provided below the main body layer 1, and the main body layer 1 and the adhesive layer 2 are connected by an adhesive. A positioning structure 3 is provided on the upper surface of the main body layer 1. The positioning structure 3 is used to cooperate with and fix the surgical template 5. The main body layer 1 is made using 3D printing technology, and the material of the main body layer 1 is a medical polymer material. The material of the adhesive layer 2 is a medical pressure-sensitive adhesive. An anti-rolling structure is provided on the edge of the adhesive layer 2. The anti-rolling structure is an arc-shaped edge extending outward from the adhesive layer 2.

[0024] In this embodiment, the adhesive layer 2 is adhered to the underside of the main body layer 1 using an adhesive. The fixation film is then placed on the patient's body surface where surgery will be performed. The medical pressure-sensitive adhesive of the adhesive layer 2 is used to adhere and fix it to the patient's body surface. Next, the groove 51 of the surgical template 5 is aligned with the protrusion 31 on the main body layer 1, and gentle pressure is applied to secure the two together. During the surgery, the main body layer 1 adheres tightly to the patient's body surface.
