Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a novel ilium extractor.
Background
In hospital bone surgery, bone grafting is a very common treatment in clinic and is commonly used to treat bone defects or bone nonunions. Because bone defects such as shoulder pelvis bone defects and bone discontinuities such as fractures are difficult to heal when the spacing between bones is large, some bones need to be filled after treatment. Ilium extraction is the most clinically safe and most commonly an important site for bone selection. The ilium is an integral part of the pelvic ring, being a flattened bone. When the upper end is taken, the bone quantity is sufficient, the bone is hard, and the supplement can be well carried out. In addition, the ilium is convenient to take, and the pelvis is non-load bone, so that more ilium is taken clinically to repair bone defects at other positions.
The ilium extractor has various shapes, such as a cylinder shape and a square cylinder shape, and is used for extracting ilium blocks with specific shapes, for example, a round bone extractor disclosed in Chinese patent No. CN 203852399U (patent name: an ilium extractor, grant notice day: 2014.10.01), and an ilium extractor disclosed in Chinese patent No. CN204683703U (patent name: an ilium extractor, grant notice day: 2015.10.07), wherein the cross section of the bone extractor body is square. The two patents can respectively take out round and square ilium blocks, and the ilium blocks can be conveniently taken out from the bone extractor by arranging the structure on the bone extractor. However, based on the fact that the bone extractor is fixed in size, the size of the extracted ilium blocks is fixed, if ilium blocks with different sizes are required to be extracted, the bone extractor needs to be replaced, the bone extractor is not universal, and the requirement of flexible bone extraction cannot be met.
Disclosure of Invention
In order to solve the defects in the prior art, the utility model provides a novel ilium extractor capable of flexibly adjusting the bone extraction size.
In order to achieve the technical purpose, the utility model adopts the following technical scheme:
the novel ilium extractor comprises an extractor body, wherein the extractor body is square as a whole, the rear end of the extractor body is connected with a handle, the top and the front of the extractor body are in an opening shape, and the front opening end of the extractor body is provided with a cutting edge; the width of the bone taking device body is adjustable.
Further, the bone taking device body comprises a fixed half body and a movable half body, the handle is connected to the rear end of the fixed half body, the front opening ends of the fixed half body and the movable half body are L-shaped, the bone taking device body is symmetrically distributed along the width direction of the bone taking device body, and the movable half body is connected with the fixed half body in a sliding mode.
Further, a slot is arranged on the opposite surface of the connection between the fixed half body and the movable half body, one side of the movable half body is slidably connected in the slot, a locking screw is arranged at the rear end of the fixed half body, and the front end of the locking screw is in contact with the movable half body.
Preferably, the cutting edge is serrated.
Preferably, the rear end of the handle is connected with a cylindrical grip.
Compared with the prior art, the utility model has the beneficial effects that:
the ilium extractor can be used for extracting the cuboid ilium to be directly applied to repairing bone defects, and the size of ilium blocks can be flexibly adjusted, so that the ilium extractor has strong universality.
