Abstract
The utility model relates to an electrotome for brain surgery, which mainly aims at providing a high-frequency electrotome applicable to scalp incision surgery. The electrotome is characterized in that a triangular support table (7) is fixedly arranged at the end of an electrotome tube (4) by a hinged pin shaft (5), and a positioning step (8) is arranged in the triangular support table (7); and the end of the electrotome tube (4) is rotated and then limited in the positioning step (8), and after the electrotome tube (4) is limited, an electrotome head (6) extends of out the horizontal plane of the bottom end of the triangular support table (7) within the length range of 1mm to 5mm. According to the electrotome for brain surgery, a support frame with a rotation limiting step is arranged on the electrotome tube, so that an operator of the electrotome is limited from artificially applying pressure, and the surgery safety can be guaranteed.
Description
Technical field
This utility model relates to a kind of surgical instrument that is applied to be used in the cerebral surgery operation scalp cutting.
Background technology
High frequency electric knife is a kind of electrosurgical unit that mechanical scalpel is organized cutting that replaces.When it contact with human body by the most advanced and sophisticated high-frequency high-voltage current that produces of active electrode tissue is heated, realize the separation of when injected organism tissue and solidify, thereby play the purpose of cutting and stopping blooding.At present in direct-view operation, such as general surgery, breast is outer, brain is outer and department of eye etc. is widely used.In department of cerebral surgery, using more field at present is in the scalp cutting operation, the characteristics such as cutting speed is fast, haemostatic effect good although high frequency electric knife has, simple to operate and safe ready, but, along with using increasing of case, find that there is a defective in it when being applied to the scalp cutting operation, that is exactly: the penetraction depth that the operator often can not fine perception electric knife self, hold that the hands of handle of a knife is always automatic exerts pressure to cutter head, bring misery to the patient thus or cause the blood coagulation difficulty.
Summary of the invention
In order to solve the technical problem of mentioning in the background technology, this utility model provides a kind of cerebral surgery operation electric knife, this kind electric knife is by being provided with one with the brace table of rotary stopper step at the cutter pipe, the operator who has limited electric knife artificially exerts pressure separately to cutter head, has guaranteed the safety of operation.
The technical solution of the utility model is: this kind cerebral surgery operation electric knife, comprise the conventional structures such as handle of a knife, cutter pipe and cutter head, be fixed with coagulation press button and TURP press button on the described handle of a knife, its unique distinction is: the end of described cutter pipe is fixed with a triangular support platform by hinging pin shaft, has a positioning step in the described triangular support platform; Be limited in the positioning step after the end rotation of described cutter pipe, after described cutter pipe was limited, cutter head leant out the length range of place, triangular support platform bottom horizontal plane between 1 millimeter～5 millimeters.
The utlity model has following beneficial effect: this kind cerebral surgery operation electric knife, be provided with one with the brace table of rotary stopper step at the cutter pipe, during use, after the rotation of cutter pipe, its end will be limited in the positioning step, thereby so that cutter head stretches out the length of place, brace table bottom surface horizontal plane fixes.Therefore, even if when operation, the doctor is automatic to exert pressure to electric knife handle, this pressure can not be applied directly to cutter head yet, but born by brace table, thereby having guaranteed that high frequency electric knife can advance according to burning vestige normally, the situation of having avoided wound to be difficult to blood coagulation occurs.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
1-handle of a knife among the figure, 2-coagulation press button, 3-TURP press button, 4-cutter pipe, 5-hinging pin shaft, 6-cutter head, 7-triangular support platform, 8-positioning step.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
In conjunction with shown in Figure 2, this kind cerebral surgery operation electric knife comprises handle of a knife 1, cutter pipe 4 and cutter head 6, is fixed with coagulation press button 2 and TURP press button 3 on the described handle of a knife 1 by Fig. 1.On above conventional structure basis, the improvements that this programme is made are: the end of described cutter pipe 4 is fixed with a triangular support platform 7 by hinging pin shaft 5, has a positioning step 8 in the described triangular support platform 7; Be limited in the positioning step 8 after the rotation of the end of described cutter pipe 4, after described cutter pipe 4 was limited, cutter head 6 leant out the length range of place, triangular support platform 7 bottom horizontal plane between 1 millimeter～5 millimeters.
During use, with the rotation of cutter pipe, its end is limited in the positioning step, cutter head namely can stretch out place, brace table bottom surface horizontal plane, when the high-frequency high-voltage current that produces of cutter head eletrode tip contacts with human body like this tissue is heated, realization is to the separation of when injected organism tissue and solidify.In case operator's mistake apply ambient pressure, this pressure will be born by the triangular support platform, and can not be applied directly to cutter head.
Claims (1)
1. cerebral surgery operation electric knife, comprise handle of a knife (1), cutter pipe (4) and cutter head (6), be fixed with coagulation press button (2) and TURP press button (3) on the described handle of a knife (1), it is characterized in that: the end of described cutter pipe (4) is fixed with a triangular support platform (7) by hinging pin shaft (5), has a positioning step (8) in the described triangular support platform (7); Be limited in the positioning step (8) after the end rotation of described cutter pipe (4), after described cutter pipe (4) was limited, cutter head (6) leant out the length range of triangular support platform (7) place, bottom horizontal plane between 1 millimeter～5 millimeters.
