Detailed Description
In order to make the technical solution of the present invention more clear and obvious to those skilled in the art, the present invention will be described in further detail with reference to examples and drawings, but the embodiments of the present invention are not limited thereto.
As shown in fig. 1-4, the positioning, drilling and threading integrated guide for coracoid process provided in this embodiment includes an integrally formed C-shaped frame assembly 2 and a hollow external threaded tube 3, the C-shaped frame assembly 2 includes a side frame 21, an upper frame 22 and a lower frame 23, an operation handle 1 is disposed at a side end of the side frame 21, at least three sets of guide holes 4 are formed in the upper frame 22, a thread hooking hole 5 corresponding to the guide hole 4 is formed in the lower frame 23, internal threads are disposed on an inner wall of the guide hole 4, and the guide hole 4 is in threaded connection with the external threaded tube 3. The upper frame 22 is 1.4-2.0cm and the lower frame 23 is 1-1.5cm in length.
As shown in fig. 4, the diameter of the hooking hole 5 gradually decreases from top to bottom at a position close to the upper frame 22.
Further, the inner diameter of the upper end of the thread hooking hole 5 is 2-2.3mm, and the inner diameter of the lower end of the thread hooking hole 5 is 1.5-2.0mm.
Further, the inner diameter of the upper end of the hooking hole 5 is smaller than the inner diameter of the guide hole 4.
Further, the external thread tube 3 has an external diameter of 3mm, an internal diameter of 2.2-2.6mm, and an internal diameter of 3mm of the pilot hole 4.
The design can avoid damage to vascular nerves and soft tissues near the coracoid process substrate caused by continuous drilling of the Kirschner wire and the electric drill, the outer diameter of the externally threaded tube 3 is equal to the inner diameter of the guide hole 4, and the inner diameter of the upper end of the thread hooking hole 5 is smaller than the outer diameter of the externally threaded tube 3, so that when the externally threaded tube 3 is abutted to the lower frame 23, the externally threaded tube 3 cannot continuously advance anymore no matter how, and the drilling is finished at the moment. Because the external thread tube 3 is matched with the guide hole 4, the punching position of the coracoid needle and the electric drill to the coracoid process can be fixed, the guide hole 4 corresponds to the thread hooking holes 5 one by one, and soft tissues and vascular nerves near the coracoid process substrate are prevented from being damaged.
Further, the side edge of the lower frame 23 is arc-shaped, and the lower frame 23 abuts against the basal portion of the coracoid process of the patient in use.
Further, the distance between the bottom end of the upper frame 22 and the top end of the lower frame 23 is 1.6-2.0cm. The coracoid process has the thickness of about 1.5cm, and the distance of 1.6-2.0cm is designed so that the guide device can avoid the phenomenon that the coracoid process cannot be blocked due to too small distance (or the coracoid process cannot be blocked due to injury to the coracoid process) and can avoid shaking due to the fact that the coracoid process cannot be blocked due to too large distance.
Further, the line between the midpoint of the two guide holes of the upper frame 22 farthest from each other and the midpoint of the two hooking holes of the lower frame 23 farthest from each other is designated as line a 7, the included angle between the line connecting the center of the guide hole of the side frame 21 farthest from each other and the hooking hole of the side frame 21 farthest from each other and the line a 7 is 25-30 °, and the included angle between the line connecting the center of the guide hole of the side frame 21 closest to each other and the hooking hole of the side frame 21 closest to each other and the line a is 8-12 °.
Because the individual differences of patients, the coracoid structures are slightly different, and through the design of the structure, the included angles between the guide holes and the line hooking holes and the line A are adjustable, so that the problem that most of patients are different in coracoid structure due to the individual differences can be solved, and the positioning accuracy is ensured.
The method for using the coracoid process positioning, drilling and threading integrated guide comprises the following steps: the skin is first incised along the outer side of the patient's collarbone to the coracoid site, muscle tissue is separated, and soft tissue surrounding the coracoid site is cleaned, and then,
step one: the doctor clamps the guide on the coracoid process 8 through the operation handle 1; the upper frame 22 is above the coracoid process 8, the lower frame 23 is abutted under the base of the coracoid process 8, the position of the guide is adjusted so that the position to be drilled is located at the center of the coracoid process 8,
step two: placing a Kirschner wire into the externally threaded tube 3, and driving the Kirschner wire and the externally threaded tube 3 into coracoid process by using an electric drill;
step three: when the external threaded pipe cannot be screwed in continuously, taking out the Kirschner wire and the electric drill;
as shown in fig. 2-3, step four: the wire 6 is fed into the externally threaded tube, and when the wire 6 penetrates the lower frame 23, the feeding of the wire 6 is continued while horizontally moving or rotating the guide along the coracoid process 8 so as to have a reversible angle, and then the guide is turned over, thereby removing the wire 6 from the hooking line Kong Gouchu. Due to the effect of the external thread pipe 3, the guide holes 4 and the thread hooking holes 5 are guaranteed to be matched one by one during drilling, so that the effect of accurate positioning is realized, and the safety is high.
Further, in the fourth step, when the steel wire 6 penetrates the lower frame 23, specifically: a position of more than 2.6cm from the lower end of the wire 6 is marked on the wire 6, and when the wire 6 goes beyond this position, the guide is horizontally moved or rotated along the coracoid process 8 to have a reversible angle, and then turned. Since the thickness of both the upper frame 22 and the lower frame 23 is 2-3mm, the distance between the bottom end of the upper frame 22 and the top end of the lower frame 23 is 1.6-2.0cm, so that the wire guide 5 is necessarily penetrated when the length of the wire entering the guide is not less than 2.6cm, the guide is horizontally moved or rotated along the coracoid process 8 to have a reversible angle, because the shape of the upper frame 22 and the lower frame 23 is curved to conform to the shape of the coracoid process 8 for the purpose of enhancing the stability, the guide must be horizontally rotated or moved along the coracoid process 8 before the guide is turned, so that the guide is angled to be turned along the coracoid process 8, and damage to the coracoid process 8 is avoided, and for a doctor who can do the operation, the guide designed in the present invention is operated as a conventional technical means to cause no damage to the coracoid process 8 when the guide is turned, the wire is guided out along with the wire guide hole 5 of the lower frame 23, as shown in detail in fig. 3. The method is simple to operate, greatly improves the operation efficiency, saves the operation time, and avoids the situation that the vascular nerves and soft tissues near the coracoid substrate are secondarily injured due to manual thread hooking by doctors. Finally, the guide is detached from the wire 6, the specific operation being known in the art, for example: the doctor uses forceps to pinch the steel wire between the coracoid substrate and the lower frame 23, separates the bottom end of the steel wire 6 from the lower frame 23, pulls down the steel wire 6, separates the top end of the steel wire 6 from the upper frame 22, completely separates the guider from the incision, and forces the steel wire 6 upwards until the top end of the steel wire 6 penetrates out of the guide hole 4.
And then or before drilling holes on the collarbone, wherein the preferable number of the holes drilled on the collarbone is 2,2 holes are respectively positioned at two sides of the holes on the coracoid process, the wires are fed in from the holes on the collarbone and hooked on the steel wires fed into the coracoid process after being fed out, the doctor continuously acts on the steel wires led out from the hooked wire holes, so that the wires are brought into the holes penetrating the coracoid process, and finally, the wires at the three holes are knotted and fixed through the titanium plate, so that the operation is completed.
The above is merely a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art will be able to apply equivalents and modifications according to the technical solution and the concept of the present invention within the scope of the present invention disclosed in the present invention.
