Abstract
The utility model provides a novel puncturing knife with a line passing hole at a knife point part, and belongs to the technical field of medical instruments. The novel puncturing knife is characterized in that the line passing hole (3) is formed at the knife point part (2), wherein a line accommodating groove (4) is formed at the back part of the line passing hole (3); and a knife body bend (5) is arranged at the back part of a knife body. The novel puncturing knife can carry a suture line or other line-shaped objects while passing through or exiting from tissues over the same way, so that the problem of single function of a traditional puncturing knife is solved; and particularly, when certain specific tasks need to be completed, the operation of a surgical doctor can be greatly facilitated, surgical injuries and surgical risks can be reduced and the surgical efficiency and the surgical effect can be improved.
Description
Technical field
This utility model belongs to technical field of medical instruments, relate to a kind ofly easily passing various more tough and tensile tissues, like cornea, sclera, tendon, ligament, cartilage even part os osseum, and can be simultaneously with the novel stab knife of suture or other threads.
Background technology
Mostly the stab knife that is widely used at present surgical operation, especially eye surgery clinically is lance type cutter (V-Lance Knife), though it has sharpness, only possesses the puncture function, and inconvenience is accomplished such as being with operations such as suture or other threads.
Summary of the invention
For fully receiving existing stab knife to have the advantage of sharpness; Can overcome again existing stab knife function singleness, inconvenience accomplish such as with the drawback of operations such as suture or other threads, we have designed and produced the novel stab knife of nose part band through wires hole on the basis of existing stab knife.Novel stab knife comprises cutter hub (1), point of a knife (2), and nose part through wires hole (3), the through wires hole rear portion holds wire casing (4), cutter hub knuckle (5), and handle (6).Cutter hub with cylindrical be good, also can be made into ellipse post or other shapes.Point of a knife is good with lance shape or spade, also can be made into sword shape, bayonet-type or other is sharp streamlined.Through wires hole is good with ellipse or obtuse angle rhombus, also can be made into circle, obtuse angle rectangle, obtuse angle square or obtuse triangle.Holding wire casing is good with the obtuse angle rectangle, also can be made into semicircle, parabola shaped, obtuse triangle, obtuse angle square etc.It is characterized in that: in nose part (2) through wires hole (3) is set, through wires hole (3) rear portion is provided with and holds wire casing (4), and cutter hub (1) rear portion is provided with cutter hub bending (5).The beneficial effect of this utility model is to pass or suture or other threads were with when withdrawing from an organization in former road; Solve the problem of traditional stab knife function singleness, especially when accomplishing some particular task, can greatly make things convenient for operation, minimizing surgical injury and operation risk, raising operation efficient and the surgical effect of operative doctor.
