[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the specification. It is obvious that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1,

[0021] like Figure 1As shown, a Kirschner wire with an injection hole, the Kirschner wire includes a Kirschner wire tip 1 and a Kirschner wire body 2. The Kirschner wire body 2 is a hollow structure with one end open, and can also be set to be open at both ends. A plurality of side holes 4 are set on the Kirschner wire body 2. An injection hose 3 is set at the open end of the Kirschner wire body 2 to facilitate the injection of drugs. The injection hose 3 is sleeved on the outside of the Kirschner wire body 2, and the injection hose 3 is tightly connected to the Kirschner wire body 2 through a connecting sleeve 6. The injection hose 3 and the connecting sleeve are an integrated structure. The internal cavities of the Kirschner wire body 2, the injection hose 3, and the connecting sleeve 6 are connected, and together with the side holes 4, form a hole for injection. Pass road.

[0022] When the injection hose 3 is sleeved on the outside of the Kirschner wire body 2, one end of the connecting sleeve 6 is integrally formed with the injection hose 3, and the other end is provided with an enlarged portion, and the enlarged portion is provided with a accommodating cavity matching the outer diameter of the Kirschner wire. One end of the injection hose 3 is connected to the Kirschner wire body 2, and the other end is provided with a cover 5. The Kirschner wire tip 1 and the Kirschner wire body 2 are both provided with a closed sleeve, and the closed sleeve 1 7 provided on the Kirschner wire tip 1 is open at one end, and the closed sleeve 2 8 provided on the Kirschner wire body 2 is open at both ends. Because the length of the Kirschner wire is much larger than the diameter of the bone, when the Kirschner wire is driven into the bone, the Kirschner wire tip 1 that is too long at both ends of the bone needs to be removed, and then the liquid will leak when driven in. Therefore, the opening of one end of the closed sleeve 1 can prevent the liquid from flowing out, and the closed sleeve 2 8 can seal the side hole 4 exposed outside the bone. The closed sleeve 1 and the closed sleeve 2 8 ensure that the injection section and the liquid flow channel are in a sterile state.

[0023] Embodiment 2: This embodiment differs from Embodiment 1 in that the connection method between the connecting sleeve 6 and the Kirschner wire is different. In this embodiment, the injection hose 3 is embedded in the Kirschner wire body 2. One end of the connecting sleeve 6 is integrally formed with the injection hose 3, and the outer diameter of the other end matches the inner diameter of the Kirschner wire. A boss 9 is provided on the outer side of the connecting sleeve 6. Figure 3 As shown, in the third embodiment, the Kirschner wire body top tube may also be configured as a structure with a hole.

[0024] Through the description of the above embodiments, those skilled in the art can clearly understand that the present invention can also be implemented through other structures, especially by combining the above several pressure-adjusting fixed arms with rod clamps, needle clamps, half rings or rings and other accessories to form various fixed brackets. Therefore, the features of the present invention are not limited to the above preferred embodiments. Any changes or modifications that can be easily thought of by any person familiar with the technology within the technical field of the present invention should be covered within the scope of patent protection of the present invention.
