Description

Bone drilling and threading needle device

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to bore bone and cross line needle device.

Background

At the final stage of the posterior and lateral hip joint replacement operation, the external rotation muscle group and the posterior joint capsule need to be sutured, and the soft tissue needs to be sutured and fixed on the bone again. The specific steps of the operation comprise: (1) marking, namely burning and marking a drilling point on the bone by an electrotome, so as to avoid losing the position of the hole when threading; (2) drilling holes, namely drilling two bone holes on the bone by using a kirschner wire at the marked point, wherein the two bone holes are generally 2cm below the tuberosity and are separated by about 2-3 cm; (3) threading, namely, threading a steel wire or a straight round needle belt, penetrating the steel wire or the straight round needle belt through the bone hole to form a loop, penetrating a No. 5 suture through the loop, and then pulling out the steel wire or the needle to lead the thread out of the bone hole; (4) knotting, namely sewing the soft tissues by using two No. 5 orthopedic sutures, wherein one suture stitches the external rotation muscle group, the other suture stitches the joint capsule, and knotting the midpoint of each suture to form four tail threads; after the bone holes penetrate out, the threads of different bone holes are knotted pairwise, so that the rear soft tissue can be fixed. It can be seen that the current kirschner wire cannot be threaded, so that after the kirschner wire drills a bone hole, a steel wire or a round needle needs to be reused for threading, and then the rear soft tissue can be knotted and fixed.

Detailed Description

It should be noted that "anterior" in this embodiment refers to a direction toward the tip of the burr, whereas "posterior" refers to a direction away from the tip of the burr.

Example 1

Example 1 provides a bone-drilling needle device, the structure of which is described in detail below.

Referring to fig. 1, the bone drilling needle passing device comprises a bone drilling needle 1 and a connecting handle 3, wherein a needle tip part of the bone drilling needle 1 is provided with a threading gap 2, and the rear end of the bone drilling needle 1 is fixedly connected with the connecting handle 3. Wherein, bore bone needle 1 and be used for boring the bone, threading breach 2 is used for the threading, and the joint handle 3 is used for the operator to hold or use the instrument centre gripping. In particular, the drill pin 1 may be a k-wire.

More specifically, the threading notch 2 includes a piercing part 21 and a thread cutting part 22, the outer wall of the needle tip part of the bone drill 1 is pierced to form the piercing part 21, the thread cutting part 22 is located inside the needle tip part of the bone drill 1, and the piercing part 21 and the thread cutting part 22 are communicated with each other. The cutting portion 22 may be located in front of or behind the perforation portion 21. In one embodiment, as shown in fig. 2, the cut line portion 22 is located in front of the perforation portion 21. In this case, after the bone hole is drilled by the drill pin 1, the thread is hung on the cutting portion 22, and the drill pin 1 is pulled back in the opposite direction out of the bone hole to form a loop.
