Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, in particular to a skull bag forming tool. Background Art

[0002] In modern neurosurgery, especially those involving neuromodulation implants, it is often necessary to create a pocket under the patient's flap tissue in order to place the implant. This process typically includes the following steps: First, the doctor will cut the patient's flap tissue to expose the skull. This step requires extremely high precision to ensure that the incision is of appropriate size and position to reduce damage to surrounding tissue. Next, the doctor will use tools such as hemostats, scalpels, and dissectors to separate the skull from the flap tissue to provide sufficient space for creating the pocket while avoiding excessive damage to the skull and flap tissue. Finally, the doctor will create a pocket in the separated space to place the implant. However, existing methods for creating a pouch present several problems: First, this method is highly dependent on the clinician's skill and experience, increasing the complexity and difficulty of the operation. Second, existing tools have limitations in actual operation, requiring the surgeon to perform precise operations within a limited surgical field of view and operating space, placing high demands on technical skills. Furthermore, due to the presence of multiple variables during the operation, the position and size of the created pouch are difficult to fully control, which may result in an incomplete match with the implant, affecting the surgical outcome. Finally, this method can easily damage the skin flap and skull, leading to uncontrollable wounds and increasing the difficulty of postoperative healing. To improve these issues, future surgical tools and techniques may need to be more intelligent and precise to improve the safety and success rate of the operation. Summary of the Invention

[0030] according to Figures 1-2 As shown, the utility model provides a skull bag forming tool. Figure 1 , including an integrated handheld component 1 and a peeling portion 2, a hole 21 is provided in the middle area of ​​the peeling portion 2, the thickness of the peeling portion 2 gradually decreases from one end close to the handheld component 1 to the end away from the handheld component 1, and the end of the peeling portion 2 away from the handheld component 1 is arc-shaped.

[0031] In the skull bag forming tool provided in an embodiment of the present invention, grooves 12 are provided on both sides of the handheld component 1. A grip portion 11 is provided in the middle region of the handheld component 1. The design of the grooves 12 and grip portion 11 on the handheld component 1 conforms to ergonomics, providing a more stable grip and improving operational accuracy. In addition, this design can also disperse hand pressure, helping to alleviate fatigue during prolonged operation.

[0032] In the skull bag forming tool provided by an embodiment of the present invention, the thickness of the handheld component 1 is greater than the thickness of the stripping part 2. In a specific embodiment, the thickness of the handheld component 1 is 7-9 mm, which can be optionally 7-8 mm or 8-9 mm, so that a gradient step 13 is formed in the vertical direction relative to the stripping part 2. The gradient step 13 can effectively relieve stress concentration, evenly disperse the stripping force, and control the stripping range by forming a thickness difference between the handheld component 1 and the stripping part 2, thereby improving the stability and accuracy of the stripping process, ensuring the high fit between the bag and the implant, reducing damage to the component during the stripping process, and extending its service life.

[0033] In the skull bag forming tool provided by the embodiment of the present invention, in a specific embodiment, the thickness of the peeling portion 2 close to the handheld component 1 is 3-4 mm, which can be optionally 3-3.5 mm or 3.5-4 mm. The thickness of the peeling portion 2 away from the handheld component 1 is 1-1.5 mm, which can be optionally 1-1.2 mm or 1.2-1.5 mm; the thickness of the peeling portion 2 gradually decreases from the end close to the handheld component 1 to the end away from the handheld component 1, with the purpose of making the peeling portion 2 present a certain angle. This design is ergonomic, which not only ensures that the doctor has a better field of view during operation, facilitating observation and operation, but also ensures that the doctor can accurately peel off the skin flap in a small or complex surgical area, thereby improving the stability and accuracy of the operation, thereby avoiding serious trauma to the skin flap or skull outside the surgical area, and helping to reduce the patient's postoperative recovery time.

[0034] In the skull bag shaping tool provided by the present invention, the stripping portion 2 is sized identically to the implant. This ensures that after the skin flap is peeled off using the skull bag shaping tool, the resulting bag precisely fits the implant, avoiding the risk of damage to the flap or skull caused by secondary or multiple adjustments to the bag. This effectively addresses the issues of bag creation during actual surgery, such as the high reliance on the clinician's skill and experience, the difficulty of tool operation, and the difficulty in controlling the bag's position and size.

[0035] In one embodiment of the skull bag shaping tool provided by the present invention, the area of ​​the hole 21 accounts for 60% to 80% of the area of ​​the peeling portion, optionally 60% to 70% or 70% to 80%. The hole 21 is designed to reduce the weight of the skull bag shaping tool itself, improve flexibility during delicate surgical operations, and thus facilitate flap peeling and precise advancement.

[0036] In the skull bag forming tool provided in the embodiment of the present invention, the material of the skull bag forming tool is a metal or non-metallic material with high strength and good biocompatibility. The metal material can be titanium and titanium alloy, cobalt-chromium alloy, stainless steel or nickel-titanium alloy, etc., and the non-metallic material can be a high-performance polymer polyetheretherketone, polyurethane, polylactic acid or polyglycolic acid, etc. The skull bag forming tool is manufactured by integrating CNC (computer numerical control), discharge or polishing processes. CNC and discharge machining technologies can achieve high-precision processing of hard materials and complex shapes, ensuring that the size and shape of the tool meet the design requirements. The polishing process can significantly improve the surface finish of the tool, thereby reducing damage to the skin flap or skull during use.

[0037] The use process of this utility model:

[0038] like Figure 2 As shown, the area of ​​the peeling portion 2 of the skull pouch-forming tool in this embodiment is pre-set based on the implant to be implanted in the patient's skull. During the surgical procedure to create the pouch beneath the flap tissue, the surgeon must first incise the patient's skull flap to expose the surgical area. Next, the surgeon, holding the skull pouch-forming tool, performs an expansion operation from the incision flap entrance, separating the skull from the flap tissue to gradually expand and form the desired pouch space. Once the subcutaneous pouch is created, the surgeon places the pre-prepared implant into the created pouch, ensuring a close fit. Final adjustments and fixation are then performed to ensure the implant's position and orientation are perfectly aligned with the intended surgical goal.

[0039] Through the above-mentioned design, the utility model provides a safe and reliable way to create a capsular bag. First, it reduces the dependence on the clinician's skills and experience, making the surgical process more standardized and controllable. Secondly, the combined use of the handheld component 1 and the peeling part 2 makes the tool operation easier, reduces the complexity and difficulty of the operation, and allows doctors to perform surgical operations more conveniently, saving surgical time, improving the success rate of the operation and the patient's postoperative recovery quality. In addition, the customized peeling part 2 ensures precise control of the position and size of the capsular bag, avoids the problem of implant mismatch due to errors, and reduces the risk of damage to the patient himself or the implant during the operation. This innovation not only has significant technical advantages, but also shows great potential and value in clinical applications.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
