Abstract
The invention discloses a medical femoral head taking device. The medical femoral head taking device comprises a sleeve and a head taking device. The sleeve is hollow, and sharp teeth are arranged at one end of the sleeve. A handle is arranged at one end of the head taking device, a connecting rod is connected to the handle, and a self-tapping threaded head is arranged at one end of the connecting rod. The head taking device can penetrate through the hollow structure of the sleeve. The medical femoral head taking device is simple in structure, convenient to operate, and capable of effectively reducing the femoral head taking difficulty, operation time is shortened, and it is guaranteed that operations are smoothly performed.
Description
Technical field
The invention belongs to technical field of medical instruments, relate in particular to a kind of medical femoral head and get head unit.
Background technology
At present, it is very general that replacement of total hip and artificial femoral head replacement have become, and is to solve the effective method of hip joint ultimate joint disease.In operation process; first will remove the femoral head of pathological changes, then implantable artificial femoral head, is still subject to the protection of surrounding soft tissue and ligament due to pathological changes femoral head; add hypertrophy and the sclerosis of pathological changes hip joint, in operation process, pathological changes femoral head is often difficult to take out from acetabular bone.
In prior art, doctor conventionally uses spiral type head extractor to be torqued into energetically in cancellous bone of femoral head and takes out femoral head, in order to control femoral head, prevents rotation, need to firmly hammer head extractor or use Kirschner wire to stablize femoral head temporarily, but therefore may cause the accidental injury of patient and operative doctor.
Summary of the invention
The object of the invention is to design a kind of medical femoral head and get head unit, can play stable femoral head, improve the hold of head extractor, thereby solve the problem existing in above-mentioned background technology.
The object of the invention is to be achieved through the following technical solutions.
A kind of femoral head is got head unit, comprises sleeve and head extractor.Described sleeve inner is hollow, and one end is pointed tooth; Described head extractor one end is handle, is connected with connecting rod on handle, and one end of connecting rod is tapping screw thread head; Described head extractor can be through the hollow structure of sleeve.
When use, the pointed tooth of sleeve is inserted to femoral head surface, can obtain capital hold, prevent femoral head rotation, then the connecting rod of head extractor is inserted to sleeve, by the femoral head of back-outing of the tapping screw thread head on connecting rod.
The invention has the beneficial effects as follows: simple in structure, easy to operate, can effectively reduce femoral head and take out difficulty, reduce operating time, ensure to perform the operation and carry out smoothly.
Brief description of the drawings
Fig. 1 is structure of the present invention and using state schematic diagram.
In figure 1, sleeve; 2, pointed tooth; 3, tapping screw thread head; 4, head extractor hands handle; 5, head extractor connecting rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
Embodiment 1.
A kind of femoral head is got head unit, comprises sleeve (1) and head extractor.Described sleeve (1) inside is hollow, and one end is pointed tooth (2); Described head extractor one end is handle (4), is connected with connecting rod (5) on handle (4), and one end of connecting rod is tapping screw thread head (3); Described head extractor can pass the hollow structure of sleeve (1).
When use, the pointed tooth of sleeve (1) is inserted to femoral head surface, can obtain capital hold, prevent femoral head rotation, then the connecting rod of head extractor (5) is inserted to sleeve (1), by the femoral head of back-outing of the tapping screw thread head (3) on connecting rod (5).
Claims (2)
1. femoral head is got a head unit, comprises sleeve and head extractor, and described sleeve inner is hollow, and one end is pointed tooth; Described head extractor one end is handle, is connected with connecting rod on handle, and one end of connecting rod is tapping screw thread head; Described head extractor can be through the hollow structure of sleeve.
2. the medical femoral head of one according to claim 1 is got head unit, it is characterized in that: the pointed tooth of sleeve one end is 2 teeth or more than 2 teeth.
