Description
Technical field
The present invention relates to medical operation device, especially a kind of knee arthroscope lower meniscus sewing needdle.
Background technology
In recent years, along with the extensively universal aged tendency of population of motion, injury of meniscus of knee joint is more and more.Used to adopt the way of partial meniscectomy or complete resection to treat meniscus injury, most of patient has received good curative effect.But the coupling obstacle of some patients were meniscectomy patella, articular degeneration aggravation, cartilage wearing and tearing increase, and have occurred too early osteoarthritis.
Meniscus is normal structure in knee joint, and it just likes buffer between condyle of femur and tibial plateau, has protected the two articular surface, absorbs the concussion of passing on downwards, and the conduction of power is distributed to face by a diffusion, reduces local stress; In addition, meniscal can also stabilized knee, meniscal wedge-like body can make up unbecoming between condyle of femur and tibial plateau, by the dead space filling around of circular condyle of femur and tibial plateau, thereby has increased kneed stability, promotes intraarticular nutrition.The above-mentioned great function playing just because of meniscus, has just guaranteed knee joint weight loading exercise and unlikely damage all the year round.
Along with people carry out deep research to meniscal biomechanical function, more and more recognize meniscal importance.Now, scholars generally believe should not be simply by the Meniscectomy of damage, and should repair as far as possible.Meniscus suturing skill is that nineteen eighty-two Henning(is prosperous peaceful) first report, through the development of 30 years, suturing skill was greatly enhanced at present.At present in the world general meniscus sewing method have in complete sew up, from inside to outside and from sewing up three kinds outside to inside.In full suturing skill recently along with the development of material is greatly developed, existing a plurality of companies develop the meniscus stiching instrument of multiple pattern, as meniscus screw, meniscus arrow, Fast-fix(meniscus fixed system) etc., the stitching of arthroscope lower meniscus is become and easily implement.Yet complete interior suturing skill is only applicable to meniscus body and the damage of part relief angle; The damage of another part meniscus relief angle needs with technology stitching from inside to outside.And the higher meniscus anterior angle damage of sickness rate does not still have good solution at present clinically, still need with applying certainly manual suture outside to inside.
At present, conventional SN carries out meniscus stitching clinically, and its shortcoming is that syringe needle is more blunt, and puncture is effort comparatively, larger to surrounding tissue and meniscus injury; Therefore, clinician uses 18G syringe needle instead and sews up meniscus sometimes, and its advantage is comparatively sharp, reduces surrounding tissue and meniscal damage; Its shortcoming is that needle tubing is shorter, and while sewing up anterior angle, often length is inadequate.In addition, clinical practice is found, no matter using SN, syringe needle, or existing meniscus sewing needle, all cannot when puncture meniscus, suture be fixed on puncture needle, often in piercing process, lead-in wire comes off or puncture needle penetrates after meniscus because puncture needle communicates with joint, the huge fluid pressure of intraarticular is gone out suture outside joint, needs again even repeated puncture of threading, threading difficulty, meniscus is sewed up more loaded down with trivial details, increased operating time and wound.
Summary of the invention
technical problem:the object of the present invention is to provide a kind of knee arthroscope lower meniscus sewing needdle, be conducive to the fixing of piercing process suture, reduce in piercing process surrounding tissue and meniscal damage.
technical scheme:for solving the problems of the technologies described above, the invention provides a kind of knee arthroscope lower meniscus sewing needdle, this sewing needle comprises: the needle body of hollow, pulley, handle, entrance hole, needle point;
Needle body comprises front portion, with the anterior rear portion being oppositely arranged with by front portion, back-connected middle part;
Needle body front portion arranges needle point, and rear portion arranges hands handle;
Described handle front portion is provided with pulley, and pulley rear portion is provided with entrance hole; Lead-in wire through pulley, passes from needle point from entrance hole penetrates.
Preferably, the length of described needle body is 6-8 centimetres.
Preferably, needle point offers otch, and this otch is inclined-plane.
Preferably, described needle body is cylindrical shape.
Preferably, handle is hexagon.
Preferably, entrance hole communicates with needle body.
beneficial effect:the present invention is simple in structure and reasonable, easy to use.Needle point is oblique opening, has avoided the circle of traditional SN blunt, reduces in piercing process surrounding tissue and meniscal damage; The long 6-8cm of needle body, and have the multiple directions such as a left side is curved, the right side is curved and upwarp available, can select by clinical practice requirement, the too short problem that has overcome syringe needle, has increased handle, convenient gripping, the pulley in handle the place ahead can be card line equipment, prevents that lead-in wire from coming off; The entrance hole opening in the place ahead of handle is visible, can under direct-view, penetrate easily lead-in wire, thereby overcome the difficulty of syringe needle and SN threading, facilitates operation technique, shortens operating time.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is sectional structure chart of the present invention.
1 is that needle body, 2 is that pulley, 3 is that handle, 4 is that entrance hole, 5 is needle point.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
The invention provides a kind of meniscus sewing needle for laparoscopic surgery, comprise needle body, pulley, handle, entrance hole, the needle point of hollow.Needle body far-end is needle point, needle point is sharp keen, be oblique opening, be conducive to soft tissue, joint capsule and meniscal puncture, needle body is the hollow medical stainless steel structure that diameter 1.5mm is about 6-8cm, can be made as the multiple directions such as a left side is curved, the right side is curved and upwarp, to meet clinical practice needs, needle body rear is connected with handle and pulley, and pulley is positioned at handle the place ahead, and there is an entrance hole at pulley rear, lead-in wire needs rotary pulley lead-in wire can be penetrated or exits after entrance hole enters, by lead-in wire, from entrance hole penetrates, rotary pulley, goes between and passes from needle point.
Needle body described in the present invention is the cylinder spline structure of 6-8 centimetre, and needle body can be made into various directions (linear type, upwarp type, left curved and right curved), can effectively arrive meniscal each position; Described handle is solid hexgonal structure, and in order to gripping, described entrance hole communicates with pulley teeth and needle body.While importing lead-in wire into from entrance hole in this routine implementation process, the pulley that rotates backward, makes lead-in wire move forward along needle body, from needle point, pass, the pulley that stops operating, lead-in wire halts, pulley can also clamp lead-in wire to a certain extent simultaneously, prevents that lead-in wire from coming off in meniscus sewing process.Threading simple and fast, saves operating time greatly, easy to operate.
