Abstract

The utility model discloses an electric knife. The electric knife comprises a knife handle and a knife head arranged at the front end of the knife handle, wherein a cavity is formed in the knife handle; a sealing clapboard is arranged in the cavity along the axial direction and divides the cavity into a circuit board space for accommodating a circuit board and a smoke channel for smoke discharge; air inlets communicated with the smoke channel are formed on one side of the knife handle, which is adjacent to the knife head; and an air outlet connected with the smoke channel and an external negative pressure pipe respectively is formed at the rear end of the knife handle. The air inlets and the air outlet are formed on the knife handle, and the smoke channel is arranged in the knife handle and communicated with the negative pressure pipe of an external negative pressure device through the air outlet, so that a large amount of smoke generated by burning or electro-coagulating human tissue during an operation can be timely sucked away and discharged; and meanwhile, the negative pressure pipe is not required to be arranged beside the knife head of the electric knife additionally, the electric knife can be flexibly operated, the operation can be smoothly performed, and operation time is saved.

Description

A kind of electric knife

Technical field

The present invention relates to medical apparatus and instruments, relate in particular to the electric knife that a kind of surgical operation is used.

Background technology

Electric knife is a kind of surgery operating theater instruments commonly used, with the little arc light that the voice frequency in each second in millions of weeks is vibrated, and cutting skin and flesh, very rapid, simultaneously sterilized automatically in the wound limit.Electric knife is burning or electricity produces a large amount of smog when coagulating tissue, and it is carcinogenic easily to suck this kind smog, can cause certain infringement to patient and medical worker; Simultaneously, a large amount of smog can influence the sight line of executing the patient, and are influential to the operation of operation.In order to address this problem, negative pressure suction device of normally extra increase is assisted and is siphoned away deleterious smog, and shortcoming is to make easily that executing the patient diverts one's attention, and has increased the complexity of operation, and has prolonged operating time.

Summary of the invention

To the shortcoming of prior art, the purpose of this utility model provides a kind of electric knife, can in time take away because of burning or electricity produces a large amount of smog when coagulating tissue, does not influence normally carrying out of operation simultaneously.

To achieve these goals; The technical scheme of this utility model is: a kind of electric knife; Comprise handle of a knife and the cutter head that is arranged on this handle of a knife front end; In said handle of a knife, be provided with hollow cavity, a seal diaphragm is set in this hollow cavity vertically, this hollow cavity is divided into the circuit board space and the smoke path that is used for smog emission that is used to place circuit board; On handle of a knife one side of contiguous cutter head, be provided with the air inlet that connects with said smoke path, be provided with the gas outlet that is connected with smoke path, outside negative pressure pipe respectively in the rear end of handle of a knife.Because air inlet and gas outlet on handle of a knife; In handle of a knife, be provided with smoke path, and this smoke path is connected with the negative pressure pipe of negative exterior pressure device through the gas outlet and communicates, when operation, can in time siphon away and discharge because of a large amount of smog that burn or electricity coagulates the tissue generation; Simultaneously do not need to increase the negative pressure pipe in addition again by electrotome head; Electric knife can flexible operating, and operation can be carried out more smoothly, saves operating time.

Preferably, said air inlet is along the axially-aligned of handle of a knife.Air inlet can be three, is arranged in a straight line vertically, more effectively draws toxic smog.

Preferably the control button of electric knife is arranged on the handle of a knife of contiguous cutter head corresponding to circuit board space, be distributed on the cambered surface of 90 degree, and air inlet is arranged on the adjacent 90 degree cambered surfaces of control button place cambered surface corresponding to smoke path.Air inlet is arranged on and makes on the adjacent 90 degree cambered surfaces of button place cambered surface, can conveniently execute the patient when grasping electric knife, and toxic smog is discharged from getting into air inlet between the tiger of executing patient's palm smoothly.

Compared with prior art, the present invention is provided with smoke path owing to air inlet and gas outlet on handle of a knife in handle of a knife; And this smoke path is connected with the negative pressure pipe of negative exterior pressure device through the gas outlet and communicates; When operation because of burning or electricity coagulates a large amount of smog that tissue produces and can in time siphon away and discharge, the while does not need to increase the negative pressure pipe in addition again by electrotome head, electric knife can flexible operating; Operation can be carried out more smoothly, saves operating time.

Below in conjunction with accompanying drawing this utility model is done further explain, but this utility model is not limited to these embodiment, any on this utility model essence spirit improvement or substitute, still belong to scope required for protection in this utility model claims.

Description of drawings

Fig. 1 is the structural representation of this utility model.

The specific embodiment

See also Fig. 1; The electric knife of present embodiment comprises handle of a knife 1 and the cutter head 2 that is arranged on this handle of a knife 1 front end; In handle of a knife 1, be provided with hollow cavity; One seal diaphragm 3 is set in this hollow cavity vertically, this hollow cavity is divided into the circuit board space 5 and the smoke path 6 that is used for smog emission that is used to place circuit board 4, circuit board 4 is connected with power line 7 respectively at cutter head 2; On handle of a knife 1 one sides of contiguous cutter head 2, be provided with three air inlets 8 that connect with smoke path 6; Air inlet 8 axially is arranged in a straight line along handle of a knife 1, is provided with the gas outlet 10 that is connected with smoke path 6, outside negative pressure pipe 9 respectively in the rear end of handle of a knife 1, and outside negative pressure pipe 9 provides suction by negative pressure device 11.Because air inlet and gas outlet on handle of a knife; In handle of a knife, be provided with smoke path, and this smoke path is connected with the negative pressure pipe of negative exterior pressure device through the gas outlet and communicates, when operation, can in time siphon away and discharge because of a large amount of smog that burn or electricity coagulates the tissue generation; Simultaneously do not need to increase the negative pressure pipe in addition again by electrotome head; Electric knife can flexible operating, and operation can be carried out more smoothly, saves operating time.(the cutting key coagulates key with electricity to the control button of electric knife; Not shown) be arranged on the handle of a knife of contiguous cutter head corresponding to circuit board space; Be distributed on the cambered surface of 90 degree, and air inlet is arranged on the adjacent 90 degree cambered surfaces of control button place cambered surface corresponding to smoke path.Air inlet is arranged on and makes on the adjacent 90 degree cambered surfaces of button place cambered surface, can conveniently execute the patient when grasping electric knife, and toxic smog is discharged from getting into air inlet between the tiger of executing patient's palm smoothly.

Though this utility model discloses as above with a preferred embodiment, be not in order to limit the scope that this utility model is implemented.Any those of ordinary skill in the art, in the invention scope that does not break away from this utility model, when can doing a little improvement, promptly every equal improvement of doing according to this utility model, the invention scope that should be this utility model is contained.
