Description

The knee arthroscope lower meniscus sewing needdle
Technical field
This utility model 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, the cartilage wearing and tearing increase, and osteoarthritis occurred too early.
Meniscus is normal structure in the knee joint, and it just as if buffer, has protected the two articular surface between condyle of femur and tibial plateau, absorb 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 remedy unbecoming between condyle of femur and tibial plateau, with dead space filling around the condyle of femur of circle and the tibial plateau, thereby has increased kneed stability, promotes intraarticular nutrition.Just because of the above-mentioned great function that meniscus plays, knee joint all the year round weight loading exercise and unlikely damage have just been guaranteed.
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 with the Meniscectomy of damage, and should repair as far as possible.The meniscus suturing skill is that nineteen eighty-two Henning(is prosperous peaceful) report that at first through the development in 30 years, suturing skill was greatly enhanced at present.At present general meniscus sewing method has and sews up, reaches from inside to outside from sewing up three kinds outside to inside in complete in the world.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, such as meniscus screw, meniscus arrow, Fast-fix(meniscus fixed system) etc., so that sewing up to become, implements easily the arthroscope lower meniscus.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 from inside to outside technology stitching.And the higher meniscus anterior angle damage of sickness rate does not still have good solution at present clinically, still need be with using certainly outside to inside manual suture.
At present, SN commonly used carries out the meniscus stitching clinically, and its shortcoming is that syringe needle is more blunt, and puncture is effort comparatively, and is larger to surrounding tissue and meniscus injury; Therefore, the clinician uses the 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 often length is inadequate when sewing up anterior angle.In addition, clinical practice is found, no matter using SN, syringe needle, or existing meniscus sewing needle, all can't when the puncture meniscus, suture be fixed on the puncture needle, often lead-in wire comes off or puncture needle penetrates behind the meniscus because puncture needle communicates with the joint in piercing process, the huge fluid pressure of intraarticular is gone out suture outside the joint, needs again threading even repeated puncture, the threading difficulty, it is more loaded down with trivial details that meniscus is sewed up, and increases operating time and wound.
Summary of the invention
Technical problem:The purpose of this utility model is to provide a kind of knee arthroscope lower meniscus sewing needdle, is conducive to the fixing of piercing process suture, reduces in the piercing process surrounding tissue and meniscal damage.
Technical scheme:For solving the problems of the technologies described above, this utility model provides a kind of knee arthroscope lower meniscus sewing needdle, and this sewing needle comprises: the needle body of hollow, pulley, handle, entrance hole, needle point;
Needle body comprises the front portion, with the anterior rear portion that is oppositely arranged with front portion, back-connected middle part;
The needle body front portion arranges needle point, and the rear portion arranges the hands handle;
Described handle front portion is provided with pulley, and the pulley rear portion is provided with entrance hole; After penetrating from entrance hole, lead-in wire through pulley, passes from needle point.
Preferably, the length of described needle body is 6-8 centimetres.
Preferably, needle point offers otch, and this otch is the inclined-plane.
Preferably, described needle body is cylindrical shape.
Preferably, handle is hexagon.
Preferably, entrance hole communicates with needle body.
Beneficial effect:This utility model is simple in structure and reasonable, easy to use.Needle point is oblique opening, has avoided the circle of traditional SN blunt, reduces in the 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 the clinical practice requirement, overcome the too short problem of syringe needle, increased handle, the convenient gripping, the pulley in handle the place ahead can be card line equipment, prevents that lead-in wire from coming off; As seen the entrance hole opening in the place ahead of handle can penetrate easily lead-in wire, thereby overcome the difficulty of syringe needle and SN threading under direct-view, make things convenient for operation technique, shortens operating time.
