Description
Technical field
The present invention relates to a kind of meniscus suture instruments, belong to medical instruments field, be applicable to the meniscus suture operation.
Background technology
Meniscus injury is a kind of joint injury of meniscus tear, how to cause by reversing external force, knee joint severe pain, can not stretch automatically, the tenderness of arthroncus and knee joint gap location, be the important evidence of judging meniscus injury.Sometimes the joint is stiff as being lockable, and " interlocking ", " snap " phenomenon occur, has seriously hindered the kneed activity of bending and stretching.Doctor trained in Western medicine thinks when knee joint is in semiflexion Qu Tiwei, suddenly in when receipts, rotation, straighten knee joint or abduction, rotation, straighten knee joint, meniscus can be stuck between condyle of femur and the femur platform and damage.
Meniscus injury is many to cause that by reversing external force when a lower limb load-bearing, shank is fixed on the semiflexion song, and during outer exhibition position, health and thigh portion be inward turning suddenly, and medial meniscus receives rotational pressure between condyle of femur and tibia, and causes meniscus tear.The knee sprung degree is bigger when spraining, and then tears after the position more leans on.
Disruptive meniscus partly slips between the joint, can make joint motion generation mechanical obstacles, hinders the joint to stretch the activity of bending, and forms by " interlocking ".In the severe trauma case, meniscus, ligamentum cruciatum and side para-ligament can damage simultaneously.
The harm of meniscus injury: pain takes place in 1, arthralgia, knee joint when a certain position, and after changing position, pain can disappear; 2, amyotrophy is main with quadriceps femoris, since meniscal damage, the knee joint limitation of activity, and with the passing of time muscle has produced disuse atrophy; Amyotrophy is serious more, and the weakness of the lower extremities phenomenon is also obvious more; 3, walking disorder, meniscus has promptly partially or completely been lost its original function because of after long term wear or acute injury break, even forms at intraarticular and to disturb, and locked joint, snap occur, influences kneed proper motion, causes the puzzlement of walking disorder.
Meniscus injury is difficult for healing usually, because meniscus blood fortune extreme difference, the overwhelming majority is an avascular area, has only the outside just near 25%～30% of joint capsule side blood supply to be arranged, so extremely difficult healing after the meniscus injury.Should in time treat according to degree of impairment once making a definite diagnosis promptly,, through interior external rotation shank, shank tried one's best stretch after the flexing, can remove the locking of knee symptom like manipulation with usual employing expectant treatment; Or immobilization treatment is through braking, drawing liquid, with Elastic bandage wrapping, with 45 ° of clamping plate or plaster fixation knee sprungs.
The meniscus suture is to treat the optimal modus operandi of meniscus injury at present, but owing to operating difficulties, the import apparatus costs an arm and a leg, and carries out acquiring a certain degree of difficulty at present.
Summary of the invention
The present invention under the prerequisite that keeps the prior art advantage, overcomes its drawback just, have easy and simple to handle, cheap, structure rationally, the advantage of simple operation.
Technical scheme of the present invention is following:
The meniscus suture instruments, by sewing needle (1), group is frustrated (2), guide pipe (3), bolt (4) is formed, it is characterized in that: sewing needle (1) needle body is elongated, and Aculeata has a pinprick; Group is frustrated (2) and is frustrated location-plate (6) and form by frustrating body (5) and group, and it is shaft-like to frustrate body (5) one-tenth, frustrates front end and bends to arc, and face is frustrated on the top; Guide pipe (3) is made up of pipe (7) and location-plate (8); Bolt (4) has two kinds of patterns, and a kind of is cylindricality, and a kind of is plate shape.
Sewing needle (1) needle body is elongated, and certain rigidity and elasticity are arranged, and Aculeata has a pinprick, is used for threading, and sewing needle (1) can be designed to plurality of specifications, selects for use when supplying operation.
Group is frustrated (2), and it is frustrated body (5) and becomes shaft-like, frustrates front end and bends to arc, and face is frustrated on the top; Be used to repair meniscus, till required requirement, group is frustrated location-plate (6) two ends has flat horizontal surface; The middle part is fluted, and group is frustrated (2) and can be designed to plurality of specifications, selects for use when supplying operation.
Guide pipe (3) is a hollow structure, and internal diameter can hold sewing needle (1) and pass, and its pipe (7) front end is radian; Front end face is the inclined-plane, can design multiple angles, has 0 °, 15 °, 30 °, 45 ° at present; Location-plate (8) two ends camber, the middle part is fluted, according to the operation demand; Guide pipe (3) can be designed to plurality of specifications, selects for use when supplying operation.
Bolt (4) has two kinds of patterns, and a kind of is cylindricality, and its two ends are taper, and the middle part is fluted, and its inner two ends are through hole, and a kind of is plate shape, and its two ends are arcuation, and the middle part has two symmetrical arc connected in stars up and down.
Through diagnose medical conditions such as CT or X-ray before the art, implement operation: confirm surgery location, frustrate (2) finishing meniscus with group; Insert sewing needle (1), select the corresponding specification of guide pipe (3), and it is penetrated according to the operation demand; Select the corresponding pattern of bolt (4), place requirements of operation.
The objective of the invention is to design a kind of with low cost; Meniscal procedure suture instruments simple in structure provides advantageous conditions for carrying out the meniscus suture, and the meniscus suture instruments is easy and simple to handle, cheap, advanced design, damage are little; Cost is low, is suitable for the orthopaedics clinical application.
