Abstract
The utility model relates to a calcar femorale reamer, which is provided with a reamer body, a transmission shaft and a sleeve handle. The sleeve handle is rotationally sleeved on the transmission shaft, the transmission shaft is fixedly connected with the reamer body, a cutting edge is arranged on the bottom surface of the reamer body, and a protective ring is arranged on the periphery of the reamer body. The protective ring arranged on the periphery of the reamer body prevents the cutting edge cutting tissues so as to increase operational safety. A boss is arranged at the center of the bottom surface of the reamer body, and the distance between the end surface of the boss and the plane of the cutting edge ranges from 0.2mm to 0.3mm, thereby providing reasonable allowance for users during reaming. In addition, the reamer is convenient and reliable in operation and has higher practical property.
Description
Technical field
This utility model relates to a kind of medical artificial joint prosthesis replacement operation apparatus, particularly a kind of bigelow's septum file.
Background technology
Artificial total hip arthroplasty can be removed disease hip pain, can recover the natural joint function again, is to treat effective method such as ischemic necrosis of femoral head, old people's fracture of femoral neck at present.Along with the improvement of the development of new bio medical material, prosthetic designs and operating perfect, the prosthetic replacement has obtained bigger progress clinically.Hip prosthesis be fixed with traditional bone cement technique for fixing and modern none-cement technique for fixing, the none-cement fixed pattern is biological fixation type artificial coxa, be to utilize the microporous layers of prosthetic surface that osseous tissue is grown into, or make it closely to embed the hip chamber by the improvement on the prosthese profile, thereby reach fixed purpose biology, it needs higher operation skill, individuation and the supporting with it apparatus that type femoral bone end prosthesis manufactures and designs, and the profile after type femoral bone end prosthesis and affected part file is repaiied is complementary.And the implantation of type femoral bone end prosthesis need use the pulp cavity file constantly to enlarge the near end of thighbone pulp cavity, file is repaiied the bigelow's septum part before implanted femur handle prosthese afterwards, bear a heavy burden and be made of certain complete girder system in the inside of proximal femur, bigelow's septum becomes one of its ingredient.
Bigelow's septum is positioned at the rear of neck of femur, body connecting portion, is the fine and close hone lamella that is positioned at the lesser trochanter deep, its down behind the shaft of femur of the utmost point and lesser trochanter below inboard cortical bone merge, before the lesser trochanter outside vertical upwards, the fusion of the rear side cortex of the last utmost point and neck of femur.Bigelow's septum is actually the extension of inboard cortex in spongiosa behind the shaft of femur, and outwards radiation reaches gluteal tuberosity, and is in the hip replacement surgery process, very important to the finishing of bigelow's septum.
Existing bigelow's septum file is mostly very simple, and it is not enough that file is repaiied in the process protection to perienchyma, has certain shortcoming.
The utility model content
The purpose of this utility model is to provide a kind of above-mentioned shortcoming that overcomes, and can effectively protect the bigelow's septum file of perienchyma.
The technical scheme that realizes this utility model purpose is: a kind of bigelow's septum file, have file body, power transmission shaft and cover handle, and cover is connected on turning set on the power transmission shaft, and power transmission shaft is fixedlyed connected with the file body, and file body bottom surface is provided with cutting edge; Described file body periphery is provided with guard ring.
The file body bottom center of above-mentioned bigelow's septum file is provided with cylinder boss, and described boss is higher than the cutting edge plane.
The raised head face of above-mentioned bigelow's septum file and the distance between the cutting edge plane are: 0.2～0.3 millimeter.
The utlity model has following characteristics: (1) this utility model file body periphery is provided with guard ring, guarantees that cutting edge can not be cut to tissue, improves operation safety; (2) this utility model file body bottom center is provided with boss, and the distance between raised head face and the cutting edge plane is 0.2～0.3 millimeter, and user is repaiied at file and guaranteed reasonably pre-allowance in the process, and is reasonable in design, easy to operate, reliable, has advantages of high practicability.
Description of drawings
