Abstract
The utility model relates to an improved high-frequency electrotome for liver surgery. The improved high-frequency electrotome comprises an electrotome bit, a handle and a power line, and the electrotome bit is in an arc shape. The improved high-frequency electrotome has the advantages that the improved high-frequency electrotome for the liver surgery overcomes the defects of a traditional linear electrotome bit, the arc-shaped electrotome bit can pass around the protruding part of the liver easily in use and cut the lower area of the liver, the traction distance of the liver is reduced, surgical procedures are simplified, and surgical difficulty is reduced; minitype shadowless lamps are arranged on the electrotome, the surgical field is made to be clear, surgical time can be saved, surgical quality and safety can be improved, and the pain of a patient can be reduced; the improved high-frequency electrotome is simple in structure, convenient to use and suitable for being widely popularized clinically.
Description
Technical field
This utility model relates to medical instruments field, specifically, is a kind of improved high frequency electric knife for liver surgery.
Background technology
High-frequency surgery electric knife is one of main apparatus of tissue cutting in surgical operation.The high-frequency surgery electric knife that used clinically at present divides head, body and afterbody three parts, and head is metal electric cutter head, and the electric knife head of different model can be installed as required; Body is handle, by shell, be placed in circuit in shell, the circuit controling switch that is installed on outer shell outer wall forms, circuit controling switch comprises coagulation switch and TURP switch; Afterbody is power line.During use, connect with the mains, open respective switch, by metal electric cutter head high frequency electric that portion produces, tissue is carried out to cutting and separating or electric coagulation hemostasis.
But traditional high-frequency surgery electric knife is all linear type cutter head; when for liver surgery; among the most of protection in right side arcus costarum of liver (lobus dexter); most of right side subcostal incision that uses during operation on liver; open the abdomen right coronary ligament ability of separated liver free liver afterwards; patient is while using ligament of separated liver week of operating theater instruments (can be electric knife), the liver of leaf direction traction left, progressively separated.When separation complete compared with upper area, even liver patient after traction finally from otch, see into, can see the cutting area that needs of liver below, but have the straight electric knife of certain volume due to the more difficult cutting and separating Dao Gai district that stops of otch and liver.
Chinese patent application CN201743764U discloses a kind of high-frequency surgery electric knife pen with LED micro-shadowless lamp, and minute head, body and afterbody three parts, is characterized in that body is also provided with LED micro-shadowless lamp and Smoking pipe passage.But yet there are no report about a kind of improved high frequency electric knife for liver surgery.
Summary of the invention
The purpose of this utility model is that a kind of improved high frequency electric knife for liver surgery is provided.
For achieving the above object, the technical scheme that this utility model is taked is: a kind of improved high frequency electric knife for liver surgery, comprise electric knife head, handle and power line three parts, and described electric knife head is circular-arc.
The angle of described circular-arc electric knife head and the axis direction of handle is 20-40 degree.
The angle of described circular-arc electric knife head and the axis direction of handle is 30 degree.
Described handle is comprised of handle casing, the circuit controling switch that is placed in the circuit in shell and is installed on outer shell outer wall, described handle one end of connection electric knife head be provided with 1-6 miniature LED shadowless lamp.
When described LED shadowless lamp is more than one, is surrounded on the surrounding of electric knife head and is uniformly distributed.
In the shell of the circuit part of described LED shadowless lamp as for handle, shadowless lamp switch is installed on outer shell outer wall, the power line plying of its power line and high-frequency surgery electric knife.
This utility model advantage is:
1, the improved high frequency electric knife for liver surgery of the present utility model, overcome the shortcoming of traditional line type electric knife head, arc electric knife head can be walked around the ledge of liver easily in use, cut to the lower zone of liver, reduced the hauling distance of liver, simplify operating procedure, reduced operating difficulty;
2, on electric knife, micro-shadowless lamp is set, makes visual area clear, can save operating time, improve operation quality and safety, alleviate patient suffering;
3, simple in structure, easy to use, be suitable for extensively promoting clinically.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the improved high frequency electric knife for liver surgery of the present utility model.
The specific embodiment
Below in conjunction with embodiment and with reference to accompanying drawing, this utility model is further described.
The Reference numeral and the ingredient that in accompanying drawing, relate to are as follows:
1. electric knife head 2. handles
3. power line 21. coagulation switches
22. TURP switch 23. shadowless lamp switches
24. LED shadowless lamps
Please refer to accompanying drawing 1, accompanying drawing 1 is the structural representation of the improved high frequency electric knife for liver surgery of the present utility model.The described improved high frequency electric knife for liver surgery, comprise electric knife head 1, handle 2 and power line 3 three parts, described electric knife head 1 is not traditional linear type, but be circular-arc, (be that in Fig. 1, angle is a) 20-40 degree, preferably 30 spend described circular-arc electric knife head 1 with the angle of the axis direction of handle 2.
Described handle 2 is comprised of handle casing, the circuit controling switch that is placed in the circuit in shell and is installed on outer shell outer wall.One end of described handle 2 is provided with 1-6 miniature LED shadowless lamp 24, and described LED shadowless lamp 24 is positioned at one end of the connection electric knife head 1 of handle 2, and when shadowless lamp is more than one, described LED shadowless lamp 24 is surrounded on the surrounding of electric knife head 1 and is uniformly distributed.In the shell of the circuit part of described LED shadowless lamp 24 as for handle 2, shadowless lamp switch 23 is installed on outer shell outer wall, the power line plying of its power line and high-frequency surgery electric knife.
The improved high frequency electric knife for liver surgery of the present utility model can be made different specifications and models as required.
The improved high frequency electric knife for liver surgery of the present utility model, overcome the shortcoming of traditional line type electric knife head, arc electric knife head can be walked around the ledge of liver easily in use, cut to the lower zone of liver, reduced the hauling distance of liver, simplify operating procedure, reduced operating difficulty; On electric knife, micro-shadowless lamp is set simultaneously, makes visual area clear, can save operating time, improve operation quality and safety, alleviate patient suffering; This utility model is simple in structure, easy to use, is suitable for extensively promoting clinically.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of this utility model principle; can also make some improvement and supplement, these improvement and supplement and also should be considered as protection domain of the present utility model.
