Description
Technical field
The present invention relates to the Multifunction expanding cutter of operation, the especially Multifunction expanding cutter of plate-like meniscal procedure under knee arthroscope.
Background technology
Outside knee joint, plate-like rupture of meniscus is the most common, for the patient of outside plate-like rupture of meniscus, doctor usually under arthroscope with operation
Cutter directly cuts, then enters to tear at meniscus from arthroscopic portal, cut meniscal during extremely easily damage normal condyle of femur cartilage,
Tibial plateau cartilage and the tissue such as blood vessel around and nerve.General surgery blade lengths is fixed, and is difficult to adapt to meniscus different parts thickness different
Feature；The cartilage of people is non-renewable, knee joint important blood vessels neurotrosis, can bring great misery, even threat to life to patient.In order to
Protection normal structure, the improvement to traditional operation cutter and meniscus cutter defect is urgently carried out.
Summary of the invention
For solving an above existing difficult problem, protection normal articular cartilage, ligamentaum cruciatum and periarticular nervus vasculairs, the invention discloses under knee arthroscope
The Multifunction expanding cutter of discoid meniscus operation, including operator sheath, secondary sheath, blade and cutting mechanism, wherein operator sheath is provided with screw
Hole, button activity groove, scale label, lock groove and twill；Secondary sheath is provided with screw hole, scale label and twill；Blade is provided with blade and carves
Degree and blade mounting holes；Cutting mechanism includes blade installation slot, elastic steel sheet, button, lock pin and tool rest.
Described operator sheath and secondary sheath are long Baltimore groove, and four angles are respectively equipped with screw hole, with the concave surface form to concave surface, are put by cutting mechanism
Between operator sheath and secondary sheath, four groups of screw holes on sheath corner that employing primary screw will coincide respectively are fixed up, and form Guan Bi sheath；Cutter
Sheet realizes assembly or disassembly by blade mounting holes with the blade installation slot on tool rest.
At button activity trough rim along being provided with 7 lock grooves, totally 6 gears (not including 0 grade), button is that an elastic steel sheet supports.Press the button
When making to press under elastic steel sheet, button together with tool rest can in sheath Stable sliding；When elastic steel sheet loses ambient pressure, then elastic steel sheet returns rapidly
Bullet, when now promoting button and lock pin to streak lock groove, lock pin is compressed by himself elastic force and is locked in lock groove by elastic steel sheet, now cutter
Seat can not slide, blade not flexible；When elastic steel sheet is pressed down, when lock pin departs from lock groove, button then blade is promoted again may be used together with tool rest
Stable sliding in sheath.Wherein, elastic steel sheet is connected on tool rest, and button can slide along button activity groove together with elastic steel sheet；Tool rest is in Guan Bi
Sheath in fit tightly can be with Stable sliding.
With time in obtuse head entrance joint, sharp cutter is hidden in handle of a knife, is marked with the scale of 0-30mm at obtuse head, in units of 1mm, and can
To carry out measuring under arthroscope in art, as the degree of depth and the distance of rupture of meniscus mouth distance capsular ligament of rupture of meniscus can be measured, both avoid damaging
Hinder normal structure, achieve again the function measured under mirror.
When arriving meniscus position to be cut, according to recording the cut degree of depth, promote the button at handle of a knife position, be divided into 1,2,3,4,5,6 altogether
Six shelves, often promote shelves, and cutting blade stretches out increase 5mm, and i.e. 1 grade blade stretches out 5mm, and 2 grades of blades stretch out 10mm, and 3 grades of blades stretch out
15mm, 4 grades of blades stretch out 20mm, and 5 grades of blades stretch out 25mm, and 6 grades of blades stretch out 30mm so that cutting blade stretches out the longest from handle of a knife
Degree, is carved with the scale in units of 1mm on the cutting blade stretched out simultaneously, in order to confirm to cut the meniscal degree of depth every time.
Button often stretches out one grade, can be pulled locking gear level by button.Including 0 grade, every time must by button again during conversion gear
Press locking of upspringing again, to prevent from automatically deviating from blade, and damage tissue.At handle of a knife grip portions, the twill arranging 2cm grips to increase doctor
Frictional force during handle of a knife.
Beneficial effect: cutter of the present invention, when being arrived tear position by arthroscopic portal, can be prevented effectively from damage periphery nervus vasculairs, femur
Cartilage, tibial plateau cartilage and the front and back normal structure such as ligamentaum cruciatum；Can carry out the position of breach accurately measuring under mirror, be pre-designed cutting
Scope and mode, thus accurately cut, preserve and protect the normal meniscus tissue to greatest extent；Avoid medical personnel's incised injury in operation；
Easy and simple to handle, twill increases frictional force, to avoid scalpel to come off from hand；Locking device, it is to avoid different transforming gears are slipped up and damaged tissue,
Improve security.
