Embodiment 1

[0020] The present invention is a hollow screw for repairing damaged ligament or tendon, such as figure 1 and figure 2 As shown, it includes a hollow screw body, the hollow screw body is composed of a nail head 3, a nail body 2 and a nail tail 1 connected in sequence, a groove 6 is opened in the upper middle of the nail tail 1, and a groove 6 is opened on the outer wall of the nail tail 1. There is a suture through hole 4, which is used for suturing and repairing the damaged ligament or tendon through the suture thread; the front end of the nail head 3 is open, and the nail head 3, the nail body 2 and the groove 6 are connected to form a The through space is used for the coaxial passage of the guide pin.

[0021] The stitching through hole 4 is opened radially and communicates with the groove 6 . The number of suture through holes 4 is 6, and they are set on the side walls corresponding to the six sides of the groove 6 respectively, and the outer axial direction of the nail...

Embodiment 2

[0025] The present invention is a hollow screw for repairing damaged ligament or tendon, such as figure 1 and image 3 As shown, it includes a hollow screw body, and the hollow screw body is composed of a nail head 3, a nail body 2 and a nail tail 1 connected in sequence, and a groove 6 is opened in the upper middle part of the nail tail 1, and the nail tail 1 A suture through hole 4 is opened on the outer side wall of the outer wall, and the suture through hole 4 is used for suturing and repairing damaged ligaments or tendons to pass through; the front end of the nail head 3 is open, and the nail head 3, nail body 2 and The grooves 6 communicate with each other to form a through space for coaxial passing of the guide pin. The suture through hole 4 is opened axially and communicates with the top wall of the nail tail 1 . When the used suture needle has a radian, the suture needle can pass through smoothly, saving operation time. The suturing through hole 4 is used for sutur...

Abstract

The invention discloses a hollow screw for repairing damaged ligaments or tendons, which comprises a hollow screw body. The hollow screw body is composed of a nail head, a nail body and a nail tail connected in sequence, and a groove is provided in the upper middle of the nail tail. , the outer wall of the nail tail is provided with a suture through hole, and the suture through hole is used for suturing and repairing the damaged ligament or tendon to pass through; the front end of the nail head is open, and the nail head, nail body and groove Interconnected to become a through space for coaxial passage of guide pins. The hollow screw used for repairing damaged ligaments or tendons can not only fix fracture fragments, but also assist in suturing and fixing damaged ligaments or tendons, which not only simplifies operation, reduces operation trauma, but also saves treatment costs.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a hollow screw for repairing damaged ligaments or tendons. Background technique [0002] Avulsion fractures of limbs are often associated with ligament or tendon damage around the fracture. In most cases, the avulsion fragment is displaced together with the ligament or tendon attached thereto. At present, the conventional surgical treatment method is: after the fracture fragment is reset, the fracture fragment is fixed with hollow screws or Kirschner wires, and the attached ligament or tendon on the fracture fragment is also stable with the fixation of the fracture fragment; The scope of ligament or tendon injury is relatively wide. When the simple fixation of the fracture fragment cannot achieve the purpose of mechanical stability, the suture fixation point, that is, the attachment point of the ligament or tendon, will be recreated on the bone of the injured ...
