Abstract
The utility model provides a little incision kneecap drag hook comprises the distal end arc portion of upwarping, the inferior lobe portion of expanding, the superior lobe portion of expanding, ARC bending portion, handheld handle and handheld handle circular pore an organic whole, the utility model discloses specially for the kneecap designs, do benefit to and fully expose thighbone distal end and shin bone near -end, especially in little incision TKA, its effect is more outstanding, has improved efficiency greatly, has shortened operation time, puts the good condition of having created for the accuracy of false body moreover.
Description
Technical field
This utility model relates to a kind of bone surgery set, particularly relates to a kind of minimal incision * patella drag hook.
Background technology
In total knee replacement operation (TKA), the process of patella also exists dispute all the time, current most scholar thinks avoid upset patella as far as possible, because patella upset may be unfavorable to the rehabilitation of postoperative quadriceps strength, and may increase the early stage pain reaction of patient.But patella does not overturn and brings difficulty to the abundant exposure of tibia and femur in operation, the patella drag hook of a particular design is there is no in clinical operation, fully operative incision is exposed to reach, lay for femur and Tibial osteotomy and prosthese and provide convenient, substitute mainly with goitre retractor or Huo Man drag hook at present, but its exposure effect is undesirable, numerous trouble is brought like this to operation, waste operating time, and prosthese may be affected put, bring catastrophic consequence even to whole operation.
Utility model content
Technical problem to be solved in the utility model is: for the defect of prior art, provides one to aim at patella design, is particularly useful in minimal incision * TKA, occasionally can be beneficial to a kind of minimal incision * patella drag hook fully exposing distal femur and proximal tibia.
This utility model is for solving the problems of the technologies described above by the following technical solutions:
A kind of minimal incision * patella drag hook, upwarps portion by far-end arc, inferior lobe expands portion, upper leaf expands portion, curved bend folding part, hand holding handle and hand holding handle circular opening integrally form.
For optimizing technique scheme further, the measure that this utility model provides also comprises:
Above-mentioned curved bend folding part radian is 2 π/3.
It is 1.6cm that above-mentioned inferior lobe expands portion's Breadth Maximum, and length is 2cm.
It is 2.2cm that above-mentioned upper leaf expands portion's Breadth Maximum, and length is 2cm.
Above-mentioned curved bend folding part width is 1.8cm, and length is 8cm.
Above-mentioned hand holding handle and junction, curved bend folding part are formed with incisura.
Above-mentioned hand holding handle length is 8cm, and width is 1.8cm.
Above-mentioned hand holding handle circular opening race diameter 2cm, inner ring diameter 1.6cm.
Above-mentioned minimal incision * patella drag hook thickness is 2mm.
Above-mentioned minimal incision * patella drag hook is that metal material makes.
This utility model adopts above technical scheme, and compared with prior art, this utility model aims at patella design, and the arc portion of upwarping is convenient to insert knee space, and be beneficial to fixing, not easily slippage, arc upwarps the smooth design in portion, unlikely damage lateral collateral ligament; Patella can be blocked when drag hook inserts more shallow in the inferior lobe portion of expanding, and is beneficial to the tractive of early stage preliminary patella; The upper leaf portion of expanding can drag hook insert comparatively deep layer face time to the further tractive of patella, when carrying out distal femur and proximal tibia synthetism and prosthese and putting, sufficient side direction tractive can be played to patella; Curved bend folding part nature arc fold bending, angulation 120 °, can reach good stability and convenience; There is incisura hand holding handle and junction, curved bend folding part, front, facilitate patient or assistant to grasp; The design of hand holding handle circular opening facilitates tractive and grasps, and not easily slips out of the hand; This utility model is especially in minimal incision * TKA, and its effect is more outstanding, substantially increases efficiency, shortens operating time, and create good condition for accurately putting of prosthese.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model, and Reference numeral is wherein: far-end arc upwarps portion 1, inferior lobe expands portion 2, upper leaf expands portion 3, curved bend folding part 4, hand holding handle 5, hand holding handle circular opening 6, incisura 7.
This utility model provides a kind of minimal incision * patella drag hook, upwarps portion 1, inferior lobe expands portion 2, upper leaf expands portion 3, curved bend folding part 4, hand holding handle 5 and hand holding handle circular opening 6 integrally form by far-end arc.
When carrying out TKA operation, arc upwarps portion 1 and is convenient to insert knee space, is beneficial to fixing, not easily slippage, and arc upwarps portion 1 for smooth design, unlikely damage lateral collateral ligament; Inferior lobe is expanded portion 2 and can block patella when drag hook inserts more shallow, is beneficial to the tractive of early stage preliminary patella; Upper leaf expand portion 3 can drag hook insert comparatively deep layer face time to the further tractive of patella, when carrying out distal femur and proximal tibia synthetism and prosthese and putting, sufficient side direction tractive can be played to patella; The natural arc fold bending in curved bend folding part 5, angulation 120 °, can reach good stability and convenience; There is incisura 7 hand holding handle 4 and junction, curved bend folding part 5, front, facilitate patient or assistant to grasp; The design of hand holding handle circular opening 6 facilitates tractive and grasps, and not easily slips out of the hand; This utility model is especially in minimal incision * TKA, and its effect is more outstanding, substantially increases efficiency, shortens operating time, and create good condition for accurately putting of prosthese.
Be described in detail specific embodiment of the utility model above, but it is as example, this utility model is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that this practicality is carried out and substituting also all among category of the present utility model.Therefore, not departing from the equalization conversion and amendment done under spirit and scope of the present utility model, all should be encompassed in scope of the present utility model.
