Abstract
The utility model discloses an arc-shaped needle knife, which comprises a handle. A straight knife rod is connected on the handle, a knife head rod is connected at the end part of the straight knife rod, arc jointing is adopts between the knife head rod and the straight knife rod, the arc angle is 5 to 90 degrees, and the end part of the knife head rod is a knife edge. The injury of the nerve and vessel caused by the abnormality of the knife edge line due to the needle knife handle is avoided from the design of the needle knife handle designed by the utility model, and the utility model initiates the beginning of bone joint bony ankylose closing operation loosening, and the operation range of the prior needle knife is broken through; the arc-shaped needle knife is suitable for chronic soft tissue injury, lumbar spine bone matrix hyperplasia and closing operation loosening to the bone joint bony ankylose.
Description
Technical field
This utility model belongs to the surgical medical apparatus, is specifically related to a kind of chronic soft tissue injuries, hyperosteogeny, osteoarthrosis bony ankylosis be carried out the loosen arcuated needle knife of usefulness of closed operation.
Background technology
The diseased region of chronic soft tissue injuries is because adhesion, cicatrix, the contracture at the terminal place of soft tissue around osteoarthrosis cause owing to be ignorant in the past, do not recognize that hyperosteogeny and joint bony ankylosis are the results of chronic soft tissue injuries yet, so, in existing technology, the closed operation apparatus of treatment chronic soft tissue injuries, hyperosteogeny mainly is a small needle knife, and does not have a closed operation apparatus to osteoarthrosis is tetanic.The purposes of existing small needle knife (diameter is less than 3 millimeters) is that soft tissue separates and acupoint stimulation, and existing pin cutter all be straight type be that the blade axis is identical with the knife bar axis, though the needle body of small needle knife size thickness difference, needle body length difference, the shape difference of blade, adhesion cicatrix on the soft tissue conduct route is not suitable for loosening of osteoarthrosis surrounding soft tissue terminal but they only are adapted to loosen.Because the osteoarthrosis of human body all is to have arcual structure, having died and having terminated in osteoarticular soft tissue is not at grade, what have arises from osteoarticular concave surface, what have arises from osteoarticular convex surface, with existing straight type pin cutter can't accurately loosen adhesion, cicatrix, the contracture of these osteoarthrosis surrounding soft tissues, so curative effect is not good enough, because existing straight type pin cutter can not enter the joint, so can not treat osteoarticular bony ankylosis.
Summary of the invention
The purpose of this utility model is to provide a kind of arcuated needle knife that can overcome existing small needle knife defective, to break through the scope of application of pin cutter.
The technical solution of the utility model is: arcuated needle knife, and it comprises handle, connects the straight knife bar on the handle, and the straight knife boom end connects the cutter head bar, and circular arc is connected between cutter head bar and the straight knife bar, and arc chord angle is 5 °～90 °, the cutter head boom end is a blade.
Described straight knife shank diameter is 1～6 millimeter.
Described cutter head bar is being a wedge shape perpendicular to the projection shape in the plane of straight knife rod axis.
The shaft section inboard of described cutter head bar has groove.Described groove is an arc groove.
This utility model is the dynamic balance imbalance according to the main diseases of chronic soft tissue injuries and hyperosteogeny, and the terminal of soft tissues such as muscle, ligament, fascia, joint capsule and adhesion, cicatrix, the contracture of the circuit of passing through thereof are the pathology frameworks that causes the dynamic balance imbalance.Thereby having formulated the application arcuated needle knife carries out pin cutter integral body around the osteoarthrosis and loosens; This pin cutter is selected the arcuated needle knife of different model for use according to the osteoarticular different radians of pathological changes, uses the method for thrusting and enters human body, arrives around the osteoarthrosis, and the soft tissue terminal is accurately loosened.Obviously improved the curative effect of chronic soft tissue injuries, osteoproliferation disease closure procedure.Patient to the osteoarthrosis bony ankylosis stretches into the joint space with arcuated needle knife, cuts off the bone fusion, reaches therapeutic purposes.Started the beginning that osteoarthrosis bony ankylosis closed operation is loosened.Broken through the scope of application of existing pin cutter, be applicable to that chronic soft tissue injuries, bone matrix hyperplasia, osteoarthrosis bony ankylosis carry out closed operation and loosen.

The specific embodiment
Present embodiment is used for the explanation to this utility model claim, and protection domain of the present utility model is not limited to the structure that the following example is described.
As shown in Figure 1, the handle 1 shape apery body shaped design of clenching fist, handle of a knife integral body is cydariform, and a side is the teeth shape, is convenient to the doctor and holds handle of a knife.Connect straight knife bar 2 on the handle 1, straight knife bar 2 ends connect cutter head bar 3, and circular arc is connected between cutter head bar 3 and the straight knife bar 2, and arc chord angle is 5 °～90 °, and cutter head bar 3 ends are blade 4.
As shown in Figure 2, arc chord angle is a-10 °, b-30 °, c-60 ° and d-90 ° four kinds between cutter head bar 3 and the straight knife bar 2, can certainly be designed to other angle as requested.
Shown in Fig. 3-1, blade is a rectilinear edge; Fig. 3-2 blade is the camber line blade.
As shown in Figure 4, the cutter head bar is a wedge shape in the plane projection perpendicular to the straight knife rod axis, be trapezoidal, promptly the cutter head bar right side look sketch map be shaped as wedge shape.
As shown in Figure 5, the shaft section inboard of cutter head bar 3 has groove 5.Groove 5 is an arc groove.
As shown in Figure 6, establish medicine-pouring pipe 6 in straight knife bar 2 and the cutter head bar 3, establish medicine-pouring hole 7 on the blade 4, medicine-pouring hole 7 links with medicine-pouring pipe 6; Establish medicine-pouring hole 8 and medicine-pouring pipe 6 link (present embodiment medicine-pouring hole 8 is located on the straight knife bar 2) on straight knife bar 2 or the handle.Can be implemented in like this when carrying out the treatment of pin cutter, to the topical of therapentic part, to improve therapeutic effect.
As shown in Figure 7, hand-held and firmly convenient for the doctor carries out pin cutter when treatment, ball pivot 9 between handle 1 and the straight knife bar 2 can be connected, establish ball pivot dog screw 10 on the handle 1.When operation, can adjust the angle of handle 1 and straight knife bar 2 like this, be convenient to doctor's operation; Dog screw 10 is used for handle 1 fixing with straight knife bar 2.Set direction indicating arm 11 on the straight knife bar 2.
The diameter of straight knife bar 2 can be selected for use between 1～6 millimeter as requested.
The cutter head bar of arcuated needle knife and the arc chord angle between the straight knife bar, knife bar diameter, the shape of cutter head bar and cutting edge shape all can be selected different model structures for use according to different therapentic parts and requirement.The shape of cutting edge shape and cutter head bar also is not limited to said structure and shape.
Be divided into three types as the I type.
As being three types with II type pin cutter:
