Abstract

The utility model discloses a kind of high-frequency surgery electric knifes with tissue removing function, including electric knife main body, and the cutter hub of the electric knife body front end, the upper knife edge being provided on the cutter hub and lower blade is arranged in；It is located at the upper knife edge or lower blade edge position on cutter hub and offers arc gap.While the utility model advantage is effectively to maintain cutting and the coagulation function of original high-frequency surgery electric knife, it facilitates doctor and passes through arc gap in the course of surgery from bottom to top, removing subcutaneous tissue and sliding flow organization operation from inside to outside, under the premise of maintaining the original operating habit of doctor not to be changed, the frequency of use for even having prevented its hetero-organization removing operation tool is reduced in operative process, effectively reduce the difficulty and sufferer pain of surgical operation, unnecessary operative incision is avoided to increase, reduce wound contamination probability and operation risk.

Description

High-frequency surgery electric knife with tissue removing function

Technical field

The utility model relates to high frequency surgical equipments, more particularly, to the high-frequency surgery electric knife with tissue removing function.

Background technique

Electric knife is a kind of electrosurgical unit of substitution mechanical operation knife progress surgical cut.It passes through electrosurgical point The thermal energy of the high frequency voltage release at end and electric discharge cut tissue, are stopped blooding.Electric current forms high temperature, thermal energy in the point of a knife of electric knife And electric discharge, make tissue fast dewatering, the decomposition, evaporation, blood clotting of contact, realizes break-up tissue and hemoglutination, reach and cut The purpose cut, stopped blooding.

Clinically the cutter hub of widely used electric knife is cutting edge structure symmetrical above and below at this stage, as shown in figure 3, its Cutting edge 1.1,1.2 can be alternatively used for cutting and blood coagulation operation, but be not easy to remove the subcutaneous tissue of interference, so that not The subcutaneous tissue be cut open, cut off will operate further surgery and generate retardance；At this moment, medical staff will be according to performing the operation Actual conditions in journey remove the obstructions such as subcutaneous tissue, mucous membrane in such a way that electric knife and other operation tools combine, to reach To surgical procedure region, open surgical field of view purpose is increased, in order to be released effectively operating space, exposure in narrow region Pathological tissues take the treatments such as reasonable excision, suture to operate, and utmostly retain the original body function of patient；But In narrow surgical procedure space using a variety of surgical instruments be bound to cause patient operative incision increase, blood loss increase and Increase bacterium infection probability, increases medical staff's surgical procedure difficulty, while secondary injury is caused to patient, operation risk is not Easily it is effectively controlled.

Summary of the invention

The utility model aim is to provide a kind of high-frequency surgery electric knife with tissue removing function.

To achieve the above object, the utility model takes following technical proposals:

High-frequency surgery electric knife described in the utility model with tissue removing function, including electric knife main body, are arranged described The cutter hub of electric knife body front end, the upper knife edge being provided on the cutter hub and lower blade；On cutter hub be located at the upper knife edge or under Arc gap is offered at blade edge position.

The arc gap is provided with the front of upper knife edge, the depth of arc gap be less than the cutter hub width two/ One.

While the utility model advantage is effectively to maintain cutting and the coagulation function of original high-frequency surgery electric knife, side Doctor pass through in the course of surgery arc gap from bottom to top, from inside to outside remove subcutaneous tissue and sliding flow organization behaviour Make, under the premise of maintaining the original operating habit of doctor not to be changed, is reduced in operative process and even prevented other The frequency of use of tissue removing operation tool effectively reduces the difficulty and sufferer pain of surgical operation, and avoiding need not The operative incision wanted increases, and reduces wound contamination probability and operation risk.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the schematic perspective view of the utility model.

Fig. 3 is the structural schematic diagram of existing electric knife cutter hub.

Specific embodiment

It elaborates with reference to the accompanying drawing to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention It puts and is implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to down State embodiment.

As shown in Figure 1, the high-frequency surgery electric knife described in the utility model with tissue removing function, including electric knife main body 1, The cutter hub 2 of 1 front end of electric knife main body is set, the upper knife edge 3.1 and lower blade 3.2 being provided on cutter hub 2；It is located on cutter hub 2 upper The forward position of blade 3.1 is offered for removing subcutaneous tissue arc gap 4, and it is wide that the depth of arc gap 4 is less than cutter hub 2 The half of degree.

In the description of the present invention, it should be noted that the orientation of the instructions such as term "front", "rear", "upper", "lower" or Positional relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description of the present invention and simplification of the description, without It is that the device of indication or suggestion meaning or element must have a particular orientation, be constructed and operated in a specific orientation, therefore not It can be interpreted as limitation of the present invention.
