Abstract
A kind of steady brill utensil of oblique surface of bone punching, it is characterized in that anti-slide cartridge (2) is welded on the both sides jaw of firm pincers (1), anti-slide cartridge is made up of two semicircular cylinders of wall thickness 1-5 millimeter, interior diameter 1-8 millimeter, the joint portion of two semicircular cylinders is while be provided with positive tooth (4), while be provided with groove (5), the length of anti-slide cartridge is 1-5 centimetre, and the far-end of anti-slide cartridge is also provided with anti-skid teeth (6); Fastening tooth (3) is provided with in the middle of the handle of firm pincers.It can reduce the number of times that drill bit pierces repeatedly, the intensity of available protecting neck of femur tuberosity lateral wall sclerotin.Reduce iatrogenic injury, be conducive to drill bit and squeeze into default position, improve the precision of boring.
Description
Technical field
This utility model is applied to clinical medicine orthopaedics, aid especially for a kind of neck of femur circular cone hollow screw guider, also plays a role very well in other oblique surface of bone punching.It relates to medical instruments field.
Background technology
At present, 10-15% patients with fracture of neck there will be doctor's almost uncontrollable complication, as nonunion and femur head necrosis etc.Its occurrence cause is relevant with primary injury and displacement fracture degree.And after anatomical reduction and stable internal fixtion, fracture bone does not connect and femur head necrosis incidence rate ought to be down to acceptable reduced levels.The method of fracture fixation has a certain impact to After femoral neck fracture ischemic necrosis and bone does not connect, many nails generally can be adopted fixing, but be positioned at the intracapsular fracture of basilar part and the serious fracture of femoral neck pulverized for some, the stability that many nails are fixed is unsatisfactory.Hollow screw internal fixtion is applicable to most of fracture of femoral neck usually.Rehnberg and Oerud finds that the intensity of greater trochanter lateral cortex has obvious impact to screw internal fixtion.According to this research, they think that screw can not be fixed on greater trochanter lateral wall securely, will be easy to complication occurs, and along with the progress of science and technology and the raising of medical skill, less invasive techniques obtains the development of advancing by leaps and bounds in surgical intervention.Traditional minimally-invasive treatment fracture of femoral neck, therapeutic method of surgery is the lower parallel hollow screw fixation of percutaneous of percutaneous X-ray machine monitoring, but the success rate that neck of femur accurately squeezed into by actual mechanical process hollow core screw is lower.Oblique surface of bone punching is very easily skidded, the hole exempting to be drilled to by force is not askew has been exactly oblique or displacement, repeated multiple times punching injures other tissue, cause iatrogenic injury, be unfavorable for that patient gets well, I have developed a kind of steady brill utensil of oblique surface of bone punching, solves the problem that the punching of medical circle oblique surface of bone is difficult.
Utility model content
The purpose of this utility model creates one drill bit can be prevented at oblique surface of bone skidding special implement, and provide a kind of steady brill device of oblique surface of bone punching, it can reduce the number of times that drill bit pierces repeatedly, the intensity of available protecting neck of femur tuberosity lateral wall sclerotin.Reduce iatrogenic injury, be conducive to drill bit and squeeze into default position, improve the precision of boring.
To achieve these goals, this utility model adopts following technical scheme:
A kind of steady brill utensil of oblique surface of bone punching, it is characterized in that anti-slide cartridge (2) is welded on the both sides jaw of firm pincers (1), anti-slide cartridge is made up of two semicircular cylinders of wall thickness 1-5 millimeter, interior diameter 1-8 millimeter, the joint portion of two semicircular cylinders is while be provided with positive tooth (4), while be provided with groove (5), the length of anti-slide cartridge is 1-5 centimetre, and the far-end of anti-slide cartridge is also provided with anti-skid teeth (6); Fastening tooth (3) is provided with in the middle of the handle of firm pincers.
Operation principle of the present utility model is: be placed on extension table by patient's anesthesia, and the oblique surface of bone of fracture, after resetting, inserts location guide pin under C-arm guides, and location guide pin is placed in neck of femur axle center, 5mm under the degree of depth to head.Skin 3cm is cut at nail tail place, guiding circular cone and compressive sleeve are installed, cortical bone outside guiding circular cone tip to tuberosity, fixing compressive sleeve, the degree of depth in the sclerotin of expliciting the position guide pin position, adjustment circular cone selects 3 conducts to enter to follow closely a little according to neck of femur diameter respectively, lays respectively at above bigelow's septum, neck of femur back upper place and front upper place, as far as possible near femoral neck bone cortex.After inserting guide pin, through C-arm perspective, guide pin is positioned at neck of femur, under Femoral cardlage, removes compressive sleeve, and location guide pin and guiding circular cone, be positioned at sclerotin length according to location guide pin respectively, calculate and the length of holing.When drill bit reaches the skidding of oblique surface of bone by pilot hole, will firmly clamp both sides jaw, anti-slide cartridge both sides separately, live drill bit with anti-skidding jacket casing, and the positive tooth of anti-slide cartridge and groove are harmonious, then fastening tooth is buckled, again the anti-skid teeth of anti-slide cartridge is propped up oblique surface of bone, boring of spudding in after finding the strong point of exerting oneself.
The utility model has the advantage of: greatly can reduce the risk occurred when drilling, improve the precision of boring of drilling simultaneously, safety and practicality are coexisted.
