Abstract
The utility model provides a threading steel needle is sewed up to meniscus, relates to medical surgical instruments, can't fix the suture on the pjncture needle when puncturing the meniscus for solving meniscus suture needles, the utility model provides a threading steel needle sharp, that can fix the suture, technical scheme be as follows: a threading steel needle is sewed up to meniscus, includes the needle bar, and the needle bar tail end is equipped with the handle, and the head end is equipped with the syringe needle that wire hook was worn in the area, the syringe needle including the tip with the tip connecting portion that meet of tip, the tip connecting portion locate on the needle bar head end, wear wire hook for in tip connecting portion lateral wall and the opening breach to the slope of tip direction, the direction of needle bar is kept away from in the sensing of breach opening. The beneficial effects of the utility model reside in that, the suture is fixed on the needle, avoids the difficulty of pjncture needle threading, prevents to drop at puncture in -process suture, reduces operation time and because the wound to the patient that the suture drops and brings.
Description
Technical field
This utility model relates to medical operation device, and especially a kind of meniscus sews up threading draw point.
Background technology
Meniscus is normal structure in knee joint, and it is between condyle of femur and tibial plateau, similarly is buffer, protects the two articular surface, absorbs the concussion passed on downwards, by the conduction of power by a diffusion to EDS maps, reduces local stress；Additionally, meniscal can also stabilized knee, it is unbecoming that meniscal wedge-like body can make up between condyle of femur and tibial plateau, by the surrounding dead space filling of circular condyle of femur with tibial plateau, thus adds kneed stability, promotion intraarticular nutrition.The above-mentioned great function played just because of meniscus, just ensure that knee joint weight loading exercise all the year round will not damage, along with people carry out in-depth study to meniscal biomechanical function, it is becoming increasingly recognized that meniscal importance.Now, scholars generally believe simply by the Meniscectomy of damage, and should should not repair as far as possible.The most general meniscus sewing method has complete interior stitching, sews up three kinds from inside to outside and from the outside to the core, in complete, suturing skill is greatly developed in the development recently as material, existing multiple companies develop the meniscus stiching instrument of multiple pattern, such as meniscus screw, meniscus arrow, Fast-fix etc. so that arthroscope lower meniscus is sewed up and become easily to implement.In complete, suturing skill is only applicable to part meniscus body and relief angle damage；The damage of meniscus relief angle need to be sewed up by technology from inside to outside, and the higher meniscus anterior angle damage of sickness rate does not the most still have good solution at present, still needs with applying manual suture from the outside to the core.
At present, commonly using SN clinically and carry out meniscus stitching, its shortcoming is that syringe needle is more blunt, punctures more laborious, bigger to surrounding tissue and meniscus injury；Therefore, clinician uses 18G syringe needle instead and sews up meniscus sometimes, and its advantage is the sharpest, reduces surrounding tissue and meniscal damage；Its shortcoming is that needle tubing is shorter, and during stitching anterior angle, often length is inadequate；In addition, clinical practice finds, no matter use SN, syringe needle, or existing meniscus sewing needle, all cannot be fixed on suture on puncture needle when puncturing meniscus, often in piercing process lead-in wire come off or puncture needle penetrate meniscus after communicate with joint due to puncture needle, suture is gone out outside joint by intraarticular huge fluid pressure, need threading even repeated puncture again, make meniscus sew up the most loaded down with trivial details, increase operating time and wound.
Utility model content
For the problem that final result is mentioned above, this utility model provides a kind of threading draw point sharp, that can fix suture, and the technical solution adopted in the utility model is as follows:
A kind of meniscus sews up threading draw point, including shank, shank tail end is provided with handle, head end is provided with the syringe needle of band threading hook for running stitch, the tip connecting portion that described syringe needle includes tip and described tip connects, described tip connecting portion is located on shank head end, and described threading hook for running stitch is the breach tilted to tip direction in tip connecting portion sidewall and opening, gap opened points to the direction away from shank, is conveniently sent by suture.During use, suture is placed in breach, delivers to the meniscus needing to sew up.
Described tip is cone, and cone apex is the sharpest, it is to avoid circle is blunt, convenient punctures to reduce surrounding tissue and meniscal damage, and cone tail end and described tip connecting portion connect, both joining parts in the same size.
Described tip connecting portion is truncated cone-shaped, and round platform is up big and down small, and the bigger end of truncated cone-shaped is corresponding with the tail end of tip to connect, both joining parts in the same size, and truncated cone-shaped small end is located at shank head end.
Described syringe needle is solid syringe needle.
The beneficial effects of the utility model are, suture is fixed on pin, it is to avoid the difficulty of puncture needle threading, and are possible to prevent suture in piercing process to come off, and reduce operating time and owing to suture comes off the wound to patient brought.
Accompanying drawing explanation
Fig. 1 is the rough schematic of threading draw point.
Detailed description of the invention
As shown in Figure 1, a kind of meniscus sews up threading draw point, including shank 1, shank tail end is provided with handle 2, shank head end is provided with the syringe needle 3 of band threading hook for running stitch 4, the tip connecting portion 32 that described syringe needle 3 includes tip 31 and described tip 31 connects, described tip connecting portion 32 is located on shank head end, and described threading hook for running stitch 4 is the breach tilted to tip 31 direction in tip connecting portion 32 sidewall and opening.During use, suture is placed in breach, deliver to the meniscus needing to sew up, described tip 31 is cone, cone apex is the sharpest, avoid circle blunt, convenient puncturing to reduce surrounding tissue and meniscal damage, cone tail end and described tip connecting portion 32 connect, both joining parts in the same size, described tip connecting portion 32 is truncated cone-shaped, round platform is up big and down small, and the bigger end of truncated cone-shaped is corresponding with the tail end of tip 31 to connect, both joining parts in the same size, truncated cone-shaped small end is located at shank head end, and described syringe needle 3 is solid syringe needle.
