Discal meniscal deformities or meniscal injuries are common diseases in the department of sports medicine, and are always the focus of attention of broad scholars on the postoperative clinical effect of the discal meniscal deformities or meniscal injuries. The discal meniscus and meniscus anterior horn injury arthroplasty under the arthroscope is a common operation formula for clinically treating patients with meniscus injury of knee joint at present, can be used for shaping the anterior horn of the discal meniscus, furthest retains the structure and the function of the meniscus, further protects the cartilage of the knee joint and delays the generation and development of knee osteoarthritis.
With the rapid development of medical industry, arthroscopy technology has the advantages of small wound, high safety, few complications, light pain degree and the like, and is widely applied to orthopedics clinic. In recent years, meniscus injury has become the most common disease in orthopedic sports medicine, wherein the arthroscopic meniscal arthroplasty repair is the most common surgical method in the current orthopedic arthroscopic surgery. The technology has the advantages that the anterior horn shaping of the disc-shaped meniscus can be repaired by directly observing and operating the meniscus in the knee joint through a tiny incision, the wound is small, the complication is few, and the like, so the technology is generally accepted by specialists and patients.
Arthroscopic knee surgery has been known for many years, and surgeons have become more sophisticated, and the arthroscopic knee instruments are also widely varied and have improved considerably over the prior art. However, currently, for a disc-shaped meniscal patient, the anterior horn of the disc-shaped meniscal is difficult to operate by using a common instrument, most clinicians perform a shaping repair on the anterior horn of the disc-shaped meniscal by using blue forceps or a conventional infinite-depth tip scalpel, but the infinite-depth protective sheath and the overlong tip blade are easy to scratch the entrance skin and subcutaneous tissues, the anterior horn of the meniscus and the anterior cruciate ligament when entering the knee joint, and the overlong blade and the overlong tip are easy to damage the tibial plateau cartilage when performing the anterior horn shaping. The device can limit the depth, shows the cutting edge length according to the thickness that the meniscus will be amputated, also reduces simultaneously because of the fracture risk of blade overlength.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve above-mentioned technical problem, designed a scalable protection sheath meniscus sword, the device can protect the interior tissue of knee joint when getting into in the knee joint, still can show the length of blade cutting edge according to the thickness of meniscus board simultaneously, avoids overlength blade cutting edge to articular cartilage's damage, has also reduced the cracked possibility of most advanced blade simultaneously.
In order to achieve the technical effects, the utility model discloses a following technical scheme realizes:
the utility model provides a scalable protection sheath meniscus sword, including meniscus point blade, the protection sheath with press the slip locking button, meniscus point blade inserts in the protection sheath, it has the spout to open on the protection sheath, meniscus point blade with set up the slip locking button fixed connection of pressing in the spout, it has a plurality of locking holes to open on the protection sheath of spout top, press the slip locking button through can recovering shell fragment and meniscus point blade fixed connection, the top of can recovering the shell fragment is fixed with the locking post, the locking post can recover the shell fragment and insert in the locking hole under the normal position state in order to lock meniscus point blade on the protection sheath, the locking post can recover the shell fragment and be in the locking hole of deviating from under the state of pressing and remove the locking of protection sheath to meniscus point blade.
Furthermore, the restorable elastic sheet is made of spring steel materials.
The utility model has the advantages that: the device can protect the tissues in the knee joint when entering the knee joint, and meanwhile, the length of the blade edge can be exposed according to the thickness of the meniscus plate, so that the damage of the overlong blade edge to the articular cartilage is avoided, and the possibility of breakage of the tip blade is reduced.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic view of a telescoping protective sheath meniscal knife configuration;
fig. 2 is a partial schematic view of a telescoping protective sheath meniscus knife.
In the drawings, the components represented by the respective reference numerals are listed below:
1-meniscal point blade, 2-protective sheath, 3-pressing sliding locking button, 4-locking hole, 5-chute, 6-locking column, and 7-recoverable spring sheet.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
A telescopic protective sheath meniscus knife comprises a meniscus point blade 1, a protective sheath 2 and a push sliding locking button 3, wherein the meniscus point blade 1 is inserted into the protective sheath 2, the protective sheath 2 is provided with a chute 5, the meniscus sharp blade 1 is fixedly connected with a pressing sliding locking button 3 arranged in the chute 5, the protective sheath 2 above the chute 5 is provided with a plurality of locking holes 4, the pressing sliding locking button 3 is fixedly connected with the meniscus sharp blade 1 through a restorable elastic sheet 7, the restorable elastic sheet 7 is made of a spring steel material, the top of the restorable elastic sheet 7 is fixed with the locking column 6, the locking column 6 is inserted into the locking hole 4 in the restorable elastic sheet 7 in the in-situ state to lock the meniscus sharp blade 1 on the protection sheath 2, and the locking column 6 is separated from the locking hole 4 in the restorable elastic sheet 7 in the pressing state to release the locking of the protection sheath 2 on the meniscus sharp blade 1.
