Description

Technical Field

[0001] This utility model relates to the technical field of hollow nail devices, specifically an injectable femoral neck hollow nail device. Background Technology

[0002] In the medical field, femoral neck fracture is a common and relatively serious type of fracture, especially among the elderly, who are prone to osteoporosis and can be fractured by even minor external forces. Young adults can also suffer such fractures due to high-energy injuries such as traffic accidents and falls from heights. Femoral neck fractures not only cause patients great pain, but also seriously affect their mobility and quality of life.

[0003] Currently, in internal fixation surgery for femoral neck fractures, the patient is usually placed in a supine position under anesthesia. The doctor uses a C-arm fluoroscopy machine to reduce the fracture site and fix the affected limb in a suitable position. Then, the needle entry point is determined on the lateral side of the femur, and a guide needle is inserted at a specific angle and direction. Drilling and tapping are then performed along the guide needle. Finally, a suitable fixation nail is screwed into the fracture site to achieve fracture fixation.

[0004] While hollow nails can stabilize the position to some extent during internal fixation surgery for femoral neck fractures, there is still a certain failure rate, which can easily lead to the femoral neck fracture not being fixed, thus affecting the patient's healing. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an injectable femoral neck hollow nail device to solve the technical problem that, in the internal fixation surgery for femoral neck fractures, hollow nails can stabilize the fixation position to a certain extent, but there is still a certain failure rate, which can easily lead to the femoral neck fracture not being fixed, thus affecting the patient's healing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an injectable femoral neck hollow nail device, comprising a hollow nail body, wherein the surface of the hollow nail body is provided with external threads, and the external threads can pass through the femoral neck fracture line, and a sleeve is provided inside the hollow nail body.

[0007] By adopting the above technical solution, the hollow nail body can pass through the femoral neck fracture line through external threads. This allows pressure to be applied to the fracture ends during fracture fixation, promoting close contact at the fracture site, reducing micromovement at the fracture ends, creating a stable environment for fracture healing, and aiding in callus growth and healing. Furthermore, when fixing the fracture site with the hollow nail body, the sleeve can be used to increase the strength of the hollow nail body, facilitating related operations and reducing surgical difficulty and the risk of secondary injury to the patient. The sleeve and hollow nail body can also deliver red bone marrow to the fracture site, promoting or accelerating fracture healing and reducing the risk of internal fixation failure.

[0008] The present invention is further configured such that the length of the sleeve is greater than the length of the hollow nail body.

[0009] By adopting the above technical solution, the top of the sleeve can be higher than the top of the hollow nail body, and the top of the sleeve can be connected to the output end of the external syringe. This facilitates the delivery of red bone marrow into the hollow nail body through the external infusion set, which helps the red bone marrow to enter the patient's fracture site through the hollow nail body, thereby promoting or accelerating fracture healing and reducing the risk of internal fixation failure.

[0010] The present invention is further configured such that the hollow nail body is made of high-performance stainless steel.

[0011] By adopting the above technical solutions, high-performance stainless steel has high strength and hardness, which can ensure that the hollow nail can withstand various stresses generated by human activity when fixing femoral neck fractures, maintain the stability of the fracture site. At the same time, the corrosion resistance of stainless steel can reduce complications such as inflammatory reactions caused by material corrosion, which helps patients' postoperative recovery and long-term health.

[0012] In summary, the present invention has the following main advantages:

[0013] This invention utilizes external threads to allow the hollow nail body to pass through the femoral neck fracture line. This allows pressure to be applied to the fracture ends during fracture fixation, promoting close contact at the fracture site, reducing micromovement at the fracture ends, creating a stable environment for fracture healing, and aiding in callus growth and healing. Furthermore, when fixing the fracture site with the hollow nail body, the sleeve can increase the strength of the hollow nail body and also deliver red bone marrow, facilitating or accelerating fracture healing and reducing the risk of internal fixation failure.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Injectable femoral neck hollow nail devices, such as Figure 1-4 As shown, the device includes a hollow nail body 1 with external threads 2 on its surface. These threads 2 can pass through the femoral neck fracture line, allowing the hollow nail body 1 to pass through the femoral neck fracture line via the external threads 2. This allows pressure to be applied to the fracture ends during fracture fixation, promoting close contact at the fracture site, reducing micromovement at the fracture ends, creating a stable environment for fracture healing, and aiding in callus growth and healing. The hollow nail body 1 also includes a sleeve 3, which increases the strength of the hollow nail body 1. Furthermore, when the hollow nail body 1 is used to fix the patient's fracture, the sleeve 3 and the hollow nail body 1 can deliver red bone marrow and other substances to the fracture site, facilitating or accelerating fracture healing and reducing the risk of internal fixation failure.

[0022] Meanwhile, the length of the sleeve 3 is greater than the length of the hollow nail body 1, which allows the external infusion set to be better connected to the top of the sleeve 3. The inner diameter of the sleeve 3 matches the output end of the external infusion set, so the sleeve 3 can be tightly connected to the external infusion set, which facilitates better delivery of red bone marrow to the patient's fracture site and increases the patient's healing.

[0023] In this embodiment, the hollow nail body 1 is made of high-performance stainless steel. The high strength and hardness of high-performance stainless steel can ensure that the hollow nail can withstand various stresses generated by human activity when fixing femoral neck fractures, and maintain the stability of the fracture site. At the same time, the corrosion resistance of stainless steel can reduce complications such as inflammatory reactions caused by material corrosion, which helps patients recover after surgery and maintain long-term health.
