Background technique
It is well known that meniscus is the semilune chondroid tissue between knee joint femoral and shin bone, it is located at shin bone
The articular surface of platform inner side and outer side.Its cross section of meniscus is triangular in shape, it is outer thickness in it is thin, above it is slightly concave, so as to stock
Bone condyle matches, here be it is flat, connect with tibial plateau.Meniscus, which has, to be increased stabilization, transfer charge, absorbs concussion, lubrication
The effects of joint.As the improvement of people's living standards, sport injury is also increasing, meniscus injury is more and more common.
Meniscus sewing method mainly divides ecto-entad (Outside-in), from inside to outside (Inside-out) He Quanguan
(All-inside) three classes in section have corresponding suture instruments according to the difference of sewing method.
In traditional a meniscus stitching unstrument structure, as shown in Figure 1, it is mainly by handle A1, setting in handle
Promoting button A2, shank A3, implant fixing piece A4 (the implant fixing piece abbreviation T, such as Fig. 2 institute that shank head end is set
Show) etc. part constitute.The main function of above-mentioned propulsion device is to get implant fixing piece from shank head end.
Above-mentioned instrument passes through meniscus through channel, and after reaching the depth location that can discharge implant fixing piece, release is simultaneously
Be unfolded implant fixing piece, keep pressure simultaneously withdraw from shank, push away line ensure it is solid and reliable；Then it knots outside joint, by knot
Device is shifted at meniscus, and extra the end of a thread is cut, and operation finishes.There is a sliding slot in the head position of shank, inside keeps an implantation
Object fixing piece, we are referred to as " T ".Traditional T is in straight panel shape, so T can follow needle point together when needle point punctures meniscus
By fiber, and when needle point retracts, T is just taken out of from sliding slot, has been then left on meniscus outer wall, to meniscus outer wall
Form first fixed point.But traditional meniscus stitching unstrument, using the implant fixing piece of linear, such knot
Structure is too simple, poor to the fixed effect of stylolite.
To sum up, how to overcome the above-mentioned technological deficiency of traditional technology is that those skilled in the art's technology urgently to be solved is asked
Topic.
