Abstract
The utility model discloses a device is implanted in acetabular bone false body location, implant the locating lever including acetabular bone examination mould, hollow sleeve, direction needle and acetabular bone, hollow sleeve has the guiding hole that supplies direction needle location direction, hollow sleeve and detachable being connected of acetabular bone examination mould, the acetabular bone is implanted the locating lever and is equipped with vertical banding side opening that runs through, confirms behind the position of acetabular bone examination mould, and fixed through the direction needle, pull out hollow sleeve and acetabular bone examination mould, select the true acetabular bone false body of suitable size to implant the true acetabular bone false body location in the exact position along direction needle location direction through acetabular bone implantation locating lever. Through the utility model discloses the location is implanted the device and is implanted true acetabular bone prosthesis location, avoids leaning on experience and range estimation to lead to true acetabular bone prosthesis to implant the position and take place the deviation, and then influences true acetabular bone prosthesis's use and survival rate, avoids the huge amount expense that the renovation brought.
Description
Technical field
The field of medical instrument technology is the utility model is related to, more particularly to a kind of acetabular component positioning implanted device.
Background technology
Acetabular component implantation is the important step of artificial hip joint total hip joint, and Replacement of Hip Joint refers to life
Thing compatibility and the prosthese of similar human femur under loading head surface made of the metal material that mechanicalness is good, are replaced using operation method
The femur facies articularis capituli destroyed by disease or injury, for eliminating lesion, recovers the operation of joint motion.
Acetabular component is when carrying out replacement operation, it is necessary to be positioned to acetabular bone angle, to ensure that postoperative prosthese matches.Mesh
Before, artificial full-hip joint acetabular component of the prior art implantation is mainly completed by experience and range estimation, or dedicated is led
Boat system, but navigation system somewhat expensive, and experience and range estimation often occur Using prosthesis when by doctor station angle or beat
Hit the influence of power size and cause final position that deviation occurs, and then influence use and the survival rate of prosthese.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of acetabular component positioning simple in structure, easy to operate
Implanted device.
Technical solution used by solve above-mentioned technical problem：A kind of acetabular component positions implanted device, including acetabular bone
Die trial, cannulated sleeve, guide pin and acetabular bone implantation locating rod, the cannulated sleeve have the guiding for guide pin positioning and guiding
Hole, the cannulated sleeve and acetabular bone die trial detachable connection, the acetabular bone implantation locating rod run through side opening equipped with vertical bar shape.
Further, the cannulated sleeve end in the middle part of acetabular bone die trial with being threadedly coupled.
Further, described cannulated sleeve the other end is equipped with easy to the hand-held handle for rotating cannulated sleeve.
Further, it is described through the direction of side opening and the axis perpendicular of acetabular bone implantation locating rod.
Beneficial effect：In this acetabular component positioning implanted device, behind the position for determining acetabular bone die trial, consolidated by guide pin
It is fixed, cannulated sleeve and acetabular bone die trial are split out, selects the true mortar prosthese of suitable size to be implanted into locating rod along guide pin by acetabular bone
Positioning and guiding is implanted into true mortar prosthese and is positioned at correct position.Implanted device is positioned by the utility model to determine true mortar prosthese
Position implantation, avoids causing true mortar Using prosthesis position that deviation occurs by experience and range estimation, so influence true mortar prosthese use and
Survival rate, avoids overhauling the enormous expenditure brought.
Brief description of the drawings
The utility model is described further with reference to the accompanying drawings and examples；
Fig. 1 is the structure diagram that acetabular bone die trial coordinates with cannulated sleeve in the utility model embodiment；
Fig. 2 is the structure diagram that guide pin coordinates with cannulated sleeve in the utility model embodiment.
Fig. 3 is that acetabular bone is implanted into the structure diagram that locating rod coordinates with true mortar prosthese in the utility model embodiment.
Embodiment
Referring to figs. 1 to Fig. 3, a kind of acetabular component positioning implanted device of the utility model, including acetabular bone die trial 1, hollow sleeve
Cylinder 2, guide pin 3 and acetabular bone implantation locating rod 4, cannulated sleeve 2 have the pilot hole for 3 positioning and guiding of guide pin, cannulated sleeve 2
With 1 detachable connection of acetabular bone die trial, specifically, 2 end of cannulated sleeve is threadedly coupled with the middle part of acetabular bone die trial 1, by turning
Cannulated sleeve 2 can realize the assembling of cannulated sleeve 2 and acetabular bone die trial 1 and separate, it is preferable that the other end of the cannulated sleeve 2
It is additionally provided with easy to the hand-held handle 6 for rotating cannulated sleeve 2.Acetabular bone implantation locating rod 4 runs through side opening 5 equipped with vertical bar shape, this is passed through
Direction and the axis perpendicular of acetabular bone implantation locating rod 4 of side opening 5 are worn, can be positioned through side opening 5 in order to observe acetabular bone implantation
Whether bar 4 is consistent with the direction of guide pin 3.
The operating process that implanted device progress acetabular component implantation is positioned by the utility model acetabular component is as follows：
Using the principle for combining top rake, the ideal position of acetabular bone die trial 1 is determined, femur side of then dislocating, acetabular bone die trial 1
Remain stationary as, diameter 10mm, the cannulated sleeve 2 that length is 28cm are combined connection with acetabular bone die trial 1；
Again along the guide pin 3 that the pilot hole of cannulated sleeve 2 pierces a diameter 3.2mm, length is 32cm, acetabular bone is drilled into
For madial wall bone untill stabilization, depth is about 0.5cm, then progressively takes out cannulated sleeve 2 and acetabular bone die trial 1, is left to be oriented to
Pin 3；
Select the true mortar prosthese 7 of suitable size, by acetabular bone be implanted into locating rod 4 along guide pin 3 by true mortar prosthese 7 squeeze into
Untill prosthese is stablized, wherein, importing direction can be conveniently observed through side opening 5 in acetabular bone implantation locating rod 4, is then taken step by step
Go out acetabular bone implantation locating rod 4 and guide pin 3, complete the implantation of true mortar prosthese 7.
The embodiment of the utility model is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
Embodiment is stated, in the knowledge that the technical field those of ordinary skill possesses, this practicality can also not departed from
Various changes can be made on the premise of new objective.
