Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a positioner for acromioclavicular joint dislocation total arthroscopic surgery.
Background
The acromioclavicular joint is dislocated and is fixed by using the double-button steel plates which are connected by the high-strength wires, the clavicle is pressed down after the high-strength wires are tightened, the gap is reduced, and the dislocation of the acromioclavicular joint is reset. The tunnel positioning point of the two steel plates is important in the operation, especially the coracoid side. The minimally invasive arthroscopy operation cannot be seen, and accurate positioning is needed in the operation. The operation does not have a better special positioner at present, generally the positioner for reconstructing the anterior cruciate ligament and the posterior cruciate ligament of the knee joint is applied, and the positioner has the following defects: during positioning in the operation, the coracoid process can not be completely exposed in the minimally invasive arthroscopy, and the observation access is generally on the outer side, so the positioning is completely based on the experience of an operator, the subjectivity is stronger, the positioning guide pin is easy to deviate, the steel plate is separated out, and the operation fails.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects and shortcomings of the prior art, and provides a acromioclavicular joint dislocation total arthroscopic surgery positioner which has simple structure, reasonable design and convenient use.
In order to achieve the above object, the utility model adopts the following technical scheme: the device comprises an arc-shaped telescopic guide frame, a first adjusting screw, a vernier caliper, a second adjusting screw, an eccentric guide sleeve, a guide pin and an eccentric column; the adjustable vernier caliper is characterized in that a first adjusting screw is arranged on the circular arc telescopic guide frame, the bottom of the circular arc telescopic guide frame is slidably inserted into one end of the vernier caliper and fixed through a second adjusting screw, an eccentric guide sleeve is fixed at the upper end of the circular arc telescopic guide frame, an eccentric column is fixed on one side of the bottom of the eccentric guide sleeve, and a guide pin is inserted into the eccentric guide sleeve.
Further, the center distance D between the eccentric column and the guide pin is 7 mm.
After the structure is adopted, the utility model discloses the beneficial effect who produces does: acromioclavicular joint dislocation total arthroscope operation locator, the coracoid width in the art of can quantizing, accurate operation site, beginner also can accomplish this operation, reduces the operation degree of difficulty, reduces operation time, the utility model has the advantages of simple structure, set up reasonable, the cost of manufacture low.
Drawings
FIG. 1 is a block diagram of the present invention;
fig. 2 is a schematic view of the width of the coracoid base of the vernier caliper end scale of the present invention.
Description of reference numerals:
the device comprises an arc-shaped telescopic guide frame 1, a first adjusting screw 2, a vernier caliper 3, a second adjusting screw 4, an eccentric guide sleeve 5, a guide pin 6 and an eccentric column 7.
Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Referring to fig. 1, the following technical solutions are adopted in the present embodiment: the device comprises an arc-shaped telescopic guide frame 1, a first adjusting screw 2, a vernier caliper 3, a second adjusting screw 4, an eccentric guide sleeve 5, a guide pin 6 and an eccentric column 7; the adjustable vernier caliper is characterized in that a first adjusting screw 2 is arranged on the circular arc telescopic guide frame 1, the bottom of the circular arc telescopic guide frame 1 is slidably inserted into one end of the vernier caliper 3 and fixed through a second adjusting screw 4, an eccentric guide sleeve 5 is fixed at the upper end of the circular arc telescopic guide frame 1, an eccentric column 7 is fixed on one side of the bottom of the eccentric guide sleeve 5, and a hollow part with the diameter of 2mm is reserved in the eccentric guide sleeve 5 so as to facilitate insertion of a guide pin 6.
The arc-shaped telescopic guide frame 1 is in an arc shape moving around the circle center B, and no matter how the guide frame moves, the eccentric guide sleeve 5 can be ensured to be aligned to the circle center B point, namely an accurate positioning point in the operation.
The center distance D between the eccentric column 7 and the guide pin 6 is 7 mm. The 7mm eccentric guide sleeve 5 is designed to be arranged at the rear edge of the clavicle, the radius of the tunnel is reduced by 2mm, 5mm is still left in the bone on the rear side, and better internal fixation support can be guaranteed.
Referring to fig. 1-2, in the operation of the present embodiment, the left side of the vernier caliper 3 can read the width L between the right sides and the width of the coracoid base of the ruler, and then the circular arc telescopic guiding frame 1 is pushed towards the inner side of the vernier caliper, the point a is the marked point, and the point a is pushed 1/2L, at this time, the point B is the midpoint of the coracoid base, which is the sought point for driving the guide pin into the precise point. After the adjustment, the second adjusting screw 4 is screwed and fixed. At the clavicle end, an eccentric column 7 in an eccentric guide sleeve 5 is abutted against the back edge of the clavicle, the guide sleeve deviates to the front, after positioning is completed, a first adjusting screw 2 is screwed, and then a guide pin 6 is driven into the eccentric guide sleeve 5 from top to bottom. The middle part of coracoid basement can be squeezed into to the guide pin, and the tunnel is placed in the middle, avoids button steel sheet slippage.
The basic principles and main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
