Example Embodiment

[0046] The present invention is further illustrated by way of examples, but will not be limited to the scope of the following examples.

[0047] like Figure 1-3 As shown, it is a placement device for the present embodiment for the bone cartilage bracket. The placement device can be reused. When used, the corresponding specification bone bone bracket is directly placed in the cylinder 1 through the opening 14, and after the use is completed, after the cleaning is disinfected, it is used for the next use.

[0048] like Figure 1-3 As shown, the placement device includes a cylinder 1, a push rod 2, one end of the cylinder 1 having a tapered head 12 integrally formed with a cylinder 1, and has an end cavity 11 along the axial direction of the cylinder 1. The inner cavity 11 is passed through the cylinder 1; the inner cavity 11 is provided with a push rod 2, and the push rod head 22 of the push rod 2 can extend into the lumen 11 in the position of the tapered head 12. The side wall of t...

Abstract

The invention discloses a placing device for an osteochondral stent. The placing device comprises a cylinder body and a push rod, wherein one end of the cylinder body is provided with a conical head integrally formed with the cylinder body, an inner cavity is formed in the cylinder body in the axis direction of the cylinder body, and the inner cavity penetrates through the cylinder body; the inner cavity is internally provided with the push rod, a push rod head of the push rod can extend into the inner cavity where the conical head is located; an opening communicating with the inner cavity is formed in the side wall of the cylinder body and is used for placing the osteochondral stent in the inner cavity. According to the placing device, the osteochondral stent for an operation is placed in the cylinder body in advance, the conical head of the cylinder body is aligned with a placing hole of the osteochondral stent which is drilled in advance during the operation, and then the osteochondral stent is pushed into the placing hole through the push rod; and therefore, the problems that the osteochondral stent is not easy to place in place, easy to lose, easy to damage and easy to invert during the operation are solved, the osteochondral stent can be conveniently implanted into the same patient for multiple times, the operation time is shortened, and the burden of the patient and medical staff is relieved.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a placement device for osteochondral brackets. Background technique [0002] Articular cartilage injury is a refractory injury in the medical field. Cartilage injury often causes symptoms such as joint swelling and pain. Due to the special structure of cartilage tissue, there are no nerves, blood vessels and lymphatic vessels in it, and the nutrient supply of cartilage is provided indirectly through joint synovial fluid; therefore, it is difficult to repair and regenerate articular cartilage after injury, and it is easy to cause obvious dysfunction. At present, cartilage scaffolds are mainly used to repair human articular cartilage tissue damage, so that patients can avoid or delay joint replacement surgery, and the cost of surgery is also greatly reduced. [0003] For cartilage repair surgery, because the drilled holes in the cartilage will overflow blood, the surgical field of ...
