Abstract
The utility model relates to a medical apparatus, in particular to a medical femoral head taking-out device used to take out a femoral head in operations, which comprises a handle and a head. The front end of the head is of a tampered drill tip with threads. A sighting sleeve is sheathed with the external side of the head. The length of the sighting sleeve is less than the length of the head. A plurality of locating teeth are evenly arranged on the edge of the front end of the sighting sleeve along the circumferential direction. The utility model has the advantages that the structure is simple, the operation is convenient, the femoral head can be taken out accurately and smoothly, and the time and the labor are saved.
Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments, is used to get capital medical head extractor in especially a kind of operation.
Background technology:
Used head extractor in the present artificial hip joint replacing operation is generally made by metallic rod, is a kind of taper thing that is similar to the T type, when being used for medical institutions' bone surgery installation hip prosthesis, takes out the used instrument of femoral head of patient's pathological changes.In operation process, with the threaded cone bur pointed drill of head to the marrow in, take out femoral head, because the femoral head spheroidal, there is slick articular cartilage on the surface, it is very difficult apex point will to be pierced in the bone operation, partially then wants repeated multiple times could take out femoral head if head extractor bores, and wastes time and energy, in addition, if slippage does not very appear in operation, can cause damaging acetabular bone, damage to the patient.
The utility model content:
This utility model provides a kind of medical head extractor, and it is simple in structure, and is easy to operate, can accurately take out femoral head smoothly, and is time saving and energy saving, solved problems of the prior art.
This utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises head extractor handle and head extractor head, the front end of head extractor head is threaded taper apex point, be set with an aiming sleeve in the outside of head extractor head, aim at the length of telescopic length less than the head extractor head; Along the circumferential direction evenly be provided with several positioning tooths at the telescopic front edge of aiming.
On the sidewall of head extractor head, be provided with rule.
The number of described positioning tooth is three.
This utility model is simple in structure, employing is at the outside of head extractor head suit one aiming sleeve, at the telescopic front edge of aiming three positioning tooths are set evenly along the circumferential direction, during operation, the positioning tooth that will aim at barrel forward end earlier places on the femoral head and accurately locatees, orientation, turn the head extractor handle then, make the cone bur pointed drill of head extractor head front end go into femoral head, the aiming sleeve can prevent to bore when the cone bur pointed drill of head extractor head front end from going into femoral head partially or slippage, make operator can once take out femoral head accurately and reliably, simple and convenient, time saving and energy saving; The rule of head extractor head sidewall can make things convenient for operator accurately to grasp and pierce the degree of depth.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, head extractor hands handle; 2, head extractor head; 3, aiming sleeve; 4, positioning tooth; 5, rule.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in FIG., this utility model comprises head extractor handle 1 and head extractor head 2, and the front end of head extractor head 2 is threaded taper apex point, is set with an aiming sleeve 3 in the outside of head extractor head 2, and the length of aiming sleeve 3 is less than the length of head extractor head 2; Front edge at aiming sleeve 3 along the circumferential direction evenly is provided with several positioning tooths 4.Head extractor handle 1 usefulness fabroil rod is made.Head extractor head 2 usefulness 1Cr18Ni9 materials are made.Aiming sleeve 3 usefulness high-quality medical stainless steel materials are made.
On the sidewall of head extractor head 2, be provided with rule 5.
The number of described positioning tooth 4 is three.
During use, three positioning tooths 4 that will aim at sleeve 3 front ends earlier place on the femoral head and accurately locate, orientation, turn head extractor handle 1 then, make the cone bur pointed drill of head extractor head 2 front ends go into femoral head, operator can by observe rule 5 on head extractor head 2 sidewalls accurately grasp head extractor head 2 front ends the taper apex point pierce the degree of depth, treat that the cone bur pointed drill to the marrow strand in the head 2/3 when going deep into, prizes femoral head then and gets final product.
This utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
