Abstract
The utility model discloses a multifunctional bent operating knife head which comprises a vertical knife handle, a bent knife head body is arranged at the front end of the knife handle, the end of the knife head is a flat body, and the root of the knife head is a prismatic body with an upward sharp corner. The bent knife head body is adopted, so that the tissue is easy to separate through the flat body in the front, operation is convenient for a surgeon, it is avoided that sub-damage is caused because a straight plate type knife is inserted too deep, the deep tissue is protected, fined dissection becomes easier to implement, and the prismatic body with the upward sharp corner is beneficial to cutting the tissue and reducing excessive electric injury caused by an excessively large contact surface.
Description
Technical field
This utility model belongs to medical apparatus and instruments, especially relates to a kind of bending multifunction surgical cutter head.
Background technology
High frequency electric knife (high frequency electro surgical unit) is a kind of some surgical instruments (electrosurgical unit, ESU) that mechanical operation cutter is organized cutting that replaces.When it contact with human body by the most advanced and sophisticated high frequency producing of active electrode (200kHz to 3MHz conventionally) high-tension current, tissue is heated, realize the separation of when injected organism tissue and solidify, thereby playing the object of cutting and stopping blooding.Conventional knife head for surgical is shaped as board-type clinically.When doing fine dissection, due to the vibration of intrinsic hand, the easily profound vital tissue of careless damage and blood vessel etc., bring secondary damage, the serious consequence such as massive hemorrhage even.We design a kind of novel bending multifunction surgical cutter head now, and surgical operation is dissected and separated incised tissue to help surgeon to become more meticulous like a cork.
Summary of the invention
The purpose of this utility model is the deficiency existing for prior art, provides a kind of simple in structure, easy to operate, is convenient to peel off tissue, avoids profoundly cutting the bending multifunction surgical cutter head that causes secondary hurt.
For achieving the above object, the technical scheme that this utility model bending multifunction surgical cutter head adopts is:
A bending multifunction surgical cutter head, comprises vertical handle of a knife, is provided with the cutter head of bending at the front end of handle of a knife, and described cutter head end is flat thallus, and root is the prismatic body that wedge angle makes progress.
The bending angle of described cutter head is 45 degree-160 degree.
Described prismatic body is triangulo column or rhombus cylinder, and wherein a drift angle upwards.
Wide 3～the 6mm of thallus of described cutter head, thickness is 0.5～2mm.
This utility model compared with prior art, has the following advantages:
(1) cutter head of bending, thallus is above convenient to chorista, is convenient to surgical operation, has avoided the cutter head of board-type to insert and has taken an advanced study into secondary hurt, has protected deep tissues, makes to become more meticulous to dissect to become simply, easily go.
(2) preparation is simple, and science is practical, and effective percentage is high, is easy to promote.
(3) the rhombus cylinder of cutter head root is conducive to incised tissue, reduces the excessive electric injury that contact surface causes too greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model bending multifunction surgical cutter head.
Fig. 2 is the B-B sectional view of thallus part in Fig. 1.
Fig. 3 is the A-A sectional view of prismatic body part in Fig. 1.
Fig. 4 is the structural representation of the various bending angles of cutter head.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate this utility model, should understand these embodiments and only for this utility model is described, be not used in restriction scope of the present utility model, after having read this utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of bending multifunction surgical cutter head is disclosed, vertical handle of a knife 1, the cutter head 2 of bending is installed at the front end of handle of a knife, the thallus 3 that is flat in the end of cutter head, the root of cutter head is the prismatic body 4 that wedge angle makes progress, the wide 3～6mm of thallus of described cutter head, and thickness is 0.5～2mm.As shown in Figure 2, the cross section of figure a thallus 3 is wherein trapezoidal; The cross section of figure b thallus 3 is rectangle; Figure c thallus 3 is class rectangle.As shown in Figure 3, the cross section of wherein scheming e prismatic body 4 is the drift angle triangle that makes progress, and prismatic body is triangulo column; The cross section of wherein scheming f prismatic body 4 is the polygon that a drift angle makes progress, and prismatic body is triangle cylinder; The cross section of wherein scheming g prismatic body 4 is the water-drop-shaped that wedge angle makes progress, and prismatic body is the water-drop-shaped cross section cylinder that wedge angle makes progress.
As shown in Figure 4, the number of degrees of the angle α of the bending angle of the cutter head of bending are 45 degree-160 degree.
Claims (4)
1. a bending multifunction surgical cutter head, comprises vertical handle of a knife, it is characterized in that: at the front end of handle of a knife, be provided with the cutter head of bending, described cutter head end is flat thallus, and root is the prismatic body that wedge angle makes progress.
