Abstract
The invention discloses an arc-shaped sawtooth shear type meniscus trimmer, relates to a minimally invasive trimming surgical instrument for meniscuses and belongs to the field of medical instruments. The trimmer is also applicable to excision of tissues in narrow gaps. The trimmer comprises two annular handles which are connected with a main rod and an auxiliary rod respectively. The main rod is provided with a sliding groove, and the auxiliary rod is located inside the sliding groove of the main rod. Front ends of both the main rod and the auxiliary rod are provided with scissor blades in a 45-degree circular arc shape which satisfies the meniscus physiological curvature, the scissor blade of the main rod is fixed, and the scissor blade of the auxiliary rod can be opened and closed. Shearing edges of scissor blades are in spiny sawtooth shapes and can fix and bite meniscus tissues required to be trimmed. According to the meniscus trimmer, when the handle of the auxiliary rod is drawn close to the handle of the main rod, the auxiliary rod slide backwards along the sliding groove of the main rod, so that the scissor blade of the auxiliary rod and the scissor blade of the main rod are closed, and sawteeth of shearing edges fix and bite tissues required to be removed. When the handle of the auxiliary rod is separated from the handle of the main rod, the auxiliary rod slide forwards along the sliding groove of the main rod, so that the scissor blade of the auxiliary rod and the scissor blade of the main rod are separated, and the cleaning process of the meniscus is finished.
Description
Technical field
The present invention relates to a kind of meniscus finishing apparatus, especially relate to a kind of arcuate serrated scissors meniscus Wicresoft prosthesis apparatus, belong to medical instruments field.
Background technology
Meniscus is one deck fibrous cartilage between knee joint femur and tibia, is divided into interior lateral meniscus, is semilune, belongs to kneed necessary structure, and the joint is stable to keeping, kicking motion shakes, the protection articular cartilage has important function.The residing position of meniscus and special construction make it cause damage or wearing and tearing easily under external force.Meniscus blood fortune is poor, is difficult for healing voluntarily, and the meniscus after damage or the wearing and tearing not only can't be born original function, but also can damage kneed other structure, causes traumatic arthritis.Therefore, if meniscus injury or wearing and tearing diagnosis is clear and definite, operative treatment early.To damage or the wearing and tearing that are positioned at the meniscus free edge, conventional modus operandi is arthroscope lower meniscus ablation or plasty.Yet, when the existing operating theater instruments of application is handled this type of meniscus injury, sting pincers (CN 202409047 U) etc. as first quarter moon Baphicacanthus cusia pincers, meniscus excision, have a lot of shortcomings, be difficult for grasping as excision extension, excessively excision easily, especially for the meniscal crude edge of wearing and tearing, then scope is cleared up in more difficult assurance; The secondary damage of meniscus is bigger, the arthritic development of postoperative acceleration of wound; Instrumentation is subjected to angle limits, and operation inconvenience causes operating time to prolong, and has increased the occurrence probability of complication such as infection; Instrumentation process complexity, young doctor is difficult for grasping, and learning time is long.
Summary of the invention
In order to overcome above-mentioned shortcoming, the invention provides a kind of arcuate serrated scissors meniscus dresser,
The technical solution adopted for the present invention to solve the technical problems is:
The present invention is made up of handle, chute connecting rod, arcuate serrated shearing blade.
The present invention is the rifle tong-like, two ring-shaped handles connect mobile jib and secondary bar respectively, mobile jib has the spill chute, secondary bar is positioned at the chute of mobile jib, and mobile jib and secondary bar front end are shearing blade, is 45 degree circular arcs, meet meniscal physiologic radian, shear edge and be serrulate, the shearing blade of mobile jib maintains static, but the shearing blade folding activity of secondary bar.
Feature of the present invention is that power is passed to bar front end shearing blade through handle along secondary bar; Mobile jib is fixed, and slides in secondary bar front and back in the mobile jib chute; The mobile jib shearing blade is fixed, but secondary bar shearing blade folding activity; Shearing blade is 45 degree circular arcs, shears edge and is serrulate.
When applying pressure to two handles of the present invention, secondary bar handle is drawn close to the mobile jib handle, the secondary bar that is connected on the handle slides backward along the chute of mobile jib, drives the shearing blade closure of shearing blade and the mobile jib of its front end, shears the meniscal tissue that sawtooth is fixing and interlock need be removed of edge on the shearing blade.When secondary bar handle and mobile jib handle separate, to front slide, the shearing blade that drives its front end separates with the shearing blade of mobile jib secondary bar, finishes a work process along the mobile jib chute, reaches the purpose of cleaning meniscus injury or wearing and tearing.
The invention has the beneficial effects as follows that the apparatus preparation is simple, with low cost; The circular arc shearing blade meets meniscal physiologic radian, and flexible operation is easy, and operating time shortens, and postoperative complication is few; The zigzag shearing blade can play fixation in the shearing meniscal while of damage, prevents the meniscus slippage; Excision extension is accurate in the art, and the secondary damage of operation is little, and meniscal crude edge is particularly suited for wearing and tearing; The apparatus feel is good, grasps easily.The present invention also is applicable to the cutting tissue in the close clearance.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is section plan of the present invention.
Fig. 2 is shearing blade vertical view of the present invention.
Fig. 3 is slide bar cross-sectional view of the present invention.
Fig. 4 is shearing blade enlarged drawing of the present invention.
Among the figure: 1. secondary bar handle 2. mobile jib handles 3. secondary bar 4. mobile jibs 5. secondary bar shearing blade 6. mobile jib shearing blade A. vertical view direction B. cross-sectional view directions.
The specific embodiment
As shown in Figure 1, keep front end mobile jib shearing blade 6 and secondary bar shearing blade 5 to be closure state before the present invention uses.Shearing blade and connecting rod are passed knee joint operation on skin otch, enter knee joint, assisting down that arthroscope monitors, determine meniscus excision position.Press secondary bar handle 1, it is drawn close to mobile jib handle 2, secondary bar 3 slides backward along the chute of mobile jib 4, drives the secondary bar shearing blade 5 and mobile jib shearing blade 6 closures of its front end, shears the meniscal tissue that sawtooth is fixing and interlock need be removed of edge on the shearing blade.When secondary bar handle 1 and mobile jib handle 2 separately, to front slide, the secondary bar shearing blade 5 that drives its front end separates with mobile jib shearing blade 6 secondary bar 3, finishes a complete work process along mobile jib 4 chutes.
