Abstract
The utility model discloses a kind of high frequency electric knife cutter head sheath, comprise two leaf symmetrical planes, connected by collapsible arc-shaped side between two leaves, wherein the lateral border of a leaf plane is strip convex surface, convex surface adopts narrow shape at the bottom of the head breadth, the lateral border of another leaf plane is strip groove, and groove adopts the narrow shape of bottom width mouth, and two planes are realize chimeric by groove with convex surface after rotating shaft doubling with arc-shaped side.By high frequency electric knife cutter head sheath of the present utility model, high frequency electric knife cutter head can be avoided to accidentally injure the tissue such as blood vessel, nerve, muscle at other position.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of novel high frequency electric knife cutter head sheath.
Background technology
High frequency electric knife can replace mechanical operation cutter and carry out tissue cutting and hemostasis, be widely used in modern surgery operation technique, its operation principle is that the high frequency voltage electric current produced by active electrode tip is heated tissue when contacting with body, realizes the separation of body tissue and solidifies.But when operating in surgical cavity cave, because working place is narrow and small, the long metal cutter head that high frequency electric knife is exposed easily causes the accidental injury of the tissues such as blood vessel, nerve, muscle.The transparent tube for transfusion of clinical normal clip is inserted in cutter head as simple and easy sheath, needs hand cutting not easily to hold length, is not easily inserted in, takes out, and tube for transfusion is made by the transparent plastic cement that do not develop, heat resistance is poor, be strayed into cave, chamber after find the shortcomings such as difficult.Therefore, the high frequency electric knife cutter head sheath that design one is simple and practical is necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of sheath for high frequency electric knife cutter head, solves the long problem easily causing the accidental injury of other tissue of high frequency electric knife cutter head by a kind of simple, economic method.
For achieving the above object, this utility model provides a kind of integrally formed formula high frequency electric knife cutter head sheath, during use, sheath fastened at cutter head and expose point of a knife position, sheath comprises two leaf symmetrical plane structures, connected by collapsible arc-shaped side between two leaves, wherein the lateral border of a leaf plane is strip convex surface, convex surface adopts narrow shape at the bottom of the head breadth, the lateral border of another leaf plane is strip groove, groove adopts the narrow shape of bottom width mouth, and two planes are realize chimeric by groove with convex surface after rotating shaft doubling with arc-shaped side.
As further improvement of the utility model, sheath plane has some vertical folding lines, to fracture sheath by folding line.Compared with prior art, the beneficial effects of the utility model are as follows.
1, integrally formed formula structure, production and processing is simple, cost is low.
2, sheath uses buckle-type, fixed.
3, sheath can by the coupling different length cutter head that simply fractures.
By following description also by reference to the accompanying drawings, this utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
Accompanying drawing explanation
The schematic diagram of Fig. 1 sheath.
The transverse section of Fig. 2 sheath.
Fig. 3 sheath loads the schematic diagram after cutter head.
Detailed description of the invention
As shown in drawings, this high frequency electric knife cutter head sheath comprises: planar structure 1; Strip convex surface 2; Strip groove 3; Arc-shaped side 4; Vertical folding line 5; Chimeric limit 6.In addition, accompanying drawing also comprises electrotome head 7; Handle of a knife 8.
This utility model provides a kind of high frequency electric knife cutter head sheath, comprise two leaf symmetrical plane structures 1, connected by collapsible arc-shaped side 4 between two leaves, wherein the lateral border of a leaf planar structure 1 is strip convex surface 2, strip convex surface 2 adopts narrow shape at the bottom of the head breadth, the lateral border of another leaf planar structure 1 is strip groove 3, and strip groove 3 adopts the narrow shape of bottom width mouth, and two symmetrical plane structures 1 realize chimeric for passing through strip groove 3 after rotating shaft doubling with strip convex surface 2 with arc-shaped side 4.In addition, sheath plane has some vertical folding lines 5, to fracture sheath by vertical folding line 5.
Claims (2)
1. a high frequency electric knife cutter head sheath, it is characterized in that: comprise two leaf symmetrical plane structures, connected by collapsible arc-shaped side between two leaves, wherein the lateral border of a leaf plane is strip convex surface, convex surface adopts narrow shape at the bottom of the head breadth, the lateral border of another leaf plane is strip groove, and groove adopts the narrow shape of bottom width mouth, and two planes are realize chimeric by groove with convex surface after rotating shaft doubling with arc-shaped side.
