Internal fixation support for fracture

Abstract

The utility model provides an internal fixation support for fracture. The internal fixation support comprises a support body, a fixing piece and a fixing nail. Locking holes are formed in the two ends of the support body and the fixing pieces, and the fixing nails penetrate into the locking holes to fix the support body. The fixing piece is arranged on the support body in a sliding mode, and the support body is a rod-shaped body and can be inserted outside periosteum or subcutaneous through a minimally invasive incision to fix bones. A plurality of locking hooks are adopted as the fixing parts, one end of each locking hook is clamped on the stent body, and the locking hooks can slide along the stent body to avoid nerves and blood vessels and are matched with the fixing nails to fix the middle part of the stent body. The technical scheme of the utility model is to supplement the existing steel plate, intramedullary nail and external fixing bracket, and is a novel fixing method between the internal fixing bracket and the external fixing bracket. The minimally invasive internal fixation device is specially used for minimally invasive internal fixation after closed reduction or small-incision minimally invasive reduction of fracture.

Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an internal fixation bracket for fractures. Background Art

[0002] Treatments for fractures can be divided into two categories: non-surgical and surgical. Non-surgical treatments include plaster or braces, functional fixation, traction and other treatments. Internal fixation is one of the surgical treatments, which generally involves surgically cutting open body tissues and then using metal rods, nails, screws or plates to fix the fracture. The internal fixation device provides support for the broken bone tissue during the healing process, while also firmly fixing the fracture site. After the wound from the internal fixation of the fracture heals, a second operation is required to remove the plates and screws. Internal fixation surgery is usually very traumatic and requires a long recovery time. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a minimally invasive internal fixation bracket for fractures, which is inserted into the lower layer of the muscle through a minimally invasive small incision to fix the skeleton.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an internal fixation bracket for fractures, including a bracket body, a fixing piece and a fixing nail; locking holes are provided on both ends of the bracket body and the fixing piece, and the fixing nails are inserted into the locking holes to fix the bracket body; the fixing piece is slidably arranged on the bracket body, and the bracket body is a rod-shaped body, which can be inserted into the periosteum or subcutaneously through a minimally invasive incision to fix the bone.

[0005] Furthermore, there are two locking holes provided at both ends of the bracket body, and the portions where the locking holes are provided are flat.

[0006] The fixing member adopts a locking hook, and there are multiple locking hooks. One end of the locking hook is clamped on the bracket body and can slide along the bracket body to avoid nerves and blood vessels, and cooperates with the fixing nail to fix the middle part of the bracket body.

[0007] The internal fixation bracket further includes a locking sleeve.

[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows: The technical solution of the present utility model is a supplement to the existing steel plates, intramedullary nails and external fixation brackets, and is a new fixation method between internal fixation and external fixation brackets. It is specifically used for minimally invasive internal fixation after closed reduction or minimally invasive reduction through a small incision of fractures. A small incision is made on the skin to insert the stent body outside the periosteum or under the skin, and then locking fixation is performed at both ends. The middle position of the stent body avoids nerves and blood vessels according to the safe zone, and is locked and fixed using a locking hook, with strong anti-torque force and good stability. Such fixation is both safe and reliable and minimally invasive, facilitating postoperative care and avoiding various inconveniences of external fixation brackets and pinhole infections. It is mainly used for minimally invasive treatment of limb fractures, and can perform closed reduction or cutting reduction. It replaces the existing steel plate fixation and external fixation bracket fixation, with very little trauma. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Referring to Figures 1-3 as shown, an internal fixation bracket for fractures includes a bracket body 1, a fixing member 2 and fixing nails. Locking holes 3 are provided at both ends of the bracket body and on the fixing member, and the fixing nails are inserted into the locking holes to fix the bracket body. The fixing member is slidably arranged on the bracket body, and the bracket body is a rod-shaped body, which can be inserted outside the periosteum or under the skin through a minimally invasive incision to fix the bone. The fixing nails have external threads, and the locking holes are machined with internal threads matching the fixing nails.

[0013] As Figure 1 shown, there are two locking holes provided at both ends of the bracket body, and the parts where the locking holes are provided are flat. The above structure facilitates the installation of the bracket and can prevent displacement at the same time.

[0014] As Figure 2 shown, the fixing member adopts a locking hook and there are multiple locking hooks. One end of the locking hook is clamped on the bracket body and can slide along the bracket body to avoid nerves and blood vessels, and cooperate with the fixing nails to fix the middle part of the bracket body. When the fixing nail is tightened, its nail cap can lock one end of the locking hook on the bracket body, enhancing the stability. The locking hooks are installed on both sides of the fracture line as needed.

[0015] As Figure 3As shown, the internal fixation bracket also includes a locking sleeve 4. The end of the locking sleeve is provided with an external thread that mates with a locking hole. When in use, the locking sleeve is first tightened to the locking hole. It should be noted that this is the case for both the locking holes on the bracket body and the fixing piece. Then, a drill bit is drilled into the bone along the internal cavity of the locking sleeve to prevent the drill bit from deviating.

[0016] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
