Abstract

This utility model relates to a kind of pencil, comprise handle, electrode and the electric knife head being connected with handle, it is characterized in that, described electrode telescopically is arranged in electric knife head, on handle, be provided with movably slide block, slide block is connected with electrode, comes that control electrode stretches out or retraction electric knife head by moving slider.The pencil that this utility model provides, electrode telescopically is arranged in electric knife head, when use, can regulate as required length, avoids causing the damage outside operative site, and security performance improves greatly, uses also very convenient; While use, in electrode retraction electric knife head, play a protective role.

Description

Pencil

Technical field

This utility model belongs to surgical operating instrument field, relates in particular to a kind of pencil.

Background technology

Pencil by make radio-frequency current pass electrode arrive tissue of patient, the position of patient and electrode contact is heated rapidly by radio-frequency current, can cut, blood coagulation, be dried or burn operation, operative site produces thermocoagulation fast, can reduce operative hemorrhage.Existing pencil generally includes handle and electrode, and electrode is fixedly mounted on handle, and electrode is electrically connected with outside high frequency generator, and handle is provided with the button for control electrode mode of operation.Because electrode has certain length, whole electrode is equal conducting radio-frequency current in the time of work, and careless slightly electrode will be encountered patient's non-operative site by mistake, and patient is caused to damage, even can cause malpractice, especially be difficult to especially avoid in the narrow and small occasion of operative space.In addition, electrode is always outside exposed, and be easy to be collided and damage, and also very unhygienic.

Summary of the invention

The purpose of this utility model is, a kind of safety and pencil easily of using is provided.

To achieve these goals, the technical solution adopted in the utility model is: a kind of pencil, comprise handle, electrode and the electric knife head being connected with handle, it is characterized in that, described electric knife head is tubulose, and electrode telescopically is arranged in electric knife head, is provided with movably slide block on handle, slide block is connected with electrode, comes that control electrode stretches out or retraction electric knife head by moving slider.

The pencil that this utility model provides, electrode telescopically is arranged in electric knife head, when use, can regulate as required length, avoids causing the damage outside operative site, and security performance improves greatly, uses also very convenient; While use, in electrode retraction electric knife head, play a protective role.

Brief description of the drawings

Fig. 1 is the three-dimensional structure diagram of this utility model pencil;

Fig. 2 is the front view of pencil;

Fig. 3 is the rearview of pencil.

Below in conjunction with accompanying drawing, this utility model is described in detail.

Detailed description of the invention

Referring to Fig. 1, pencil comprises handle 1, electric knife head 2 and electrode 3, and one end of electric knife head 2 connecting handles 1 is the tubulose of hollow.Electrode 3 telescopicallies are arranged in the cavity of electric knife head 2, can move at axis direction relative to electric knife head 2.Referring to Fig. 2, on the wall of handle 1, be provided with movably slide block 5, slide block 5 is connected with electrode 3, comes that control electrode 3 stretches out or retraction electric knife head 2 by moving slider 5.The length that can regulate as required electrode to stretch out electric knife head when use, avoids causing the damage outside operative site, and security performance improves greatly, uses also very convenient; While use, in electrode retraction electric knife head, play a protective role.

Handle 1 is being provided with three light-emitting components 4 near electric knife head 2 one end, and light-emitting component 4 is evenly arranged at the circumferencial direction of handle 1, for illuminating operative site.Handle 1 is provided with lighting button 6, built-in circuit in handle 1, and lighting button 6 is electrically connected with light-emitting component 4 by built-in circuit, for controlling light-emitting component 4.Referring to Fig. 2 and Fig. 3, on handle 1, be also provided with two button electrodes 71 and 72, the built-in circuit in button electrode and the equal connecting handle 1 of electrode 3, circuit is electrically connected with high frequency generator by external plug again, and high frequency generator provides radio-frequency current for electrode 3.Electrode 3 has TURP and two kinds of mode of operations of coagulation, a kind of mode of operation of two each control electrodes of button electrode, that is to say, press one of them button electrode, what in electrode 3, pass into is a kind of electric current of frequency wherein, is TURP mode of operation, presses another button electrode, what in electrode 3, pass into is the electric current of another kind of frequency, is coagulation mode of operation.

Handle 1 is provided with pipe 8, and pipe 8 is communicated with electric knife head 2, the smog that electrode 3 produces while carrying out the operation of TURP or coagulation pass through successively electric knife head 2 and pipe 8 from human body out.Pipe 8, slide block 5, lighting button 6 and button electrode on the wall of the same axial location of handle along being circumferentially evenly arranged, adjacent angle is between the two 90 degree, that is to say, pipe 8, slide block 5, lighting button 6 and button electrode are arranged in four of the same axial location of handle not on ipsilateral.By slide block 5, lighting button 6 and button electrode centralized arrangement on the same axial location of handle, the hands that doctor holds pencil in the time of operation technique is without change place, only remove to carry out different operating with finger, be convenient to position and curable grip that doctor keeps pencil, be conducive to improve operation precision and save operating time.

Claims

1. a pencil, comprise handle, electrode and the electric knife head being connected with handle, it is characterized in that, described electric knife head is tubulose, and electrode telescopically is arranged in electric knife head, is provided with movably slide block on handle, slide block is connected with electrode, come by moving slider that control electrode stretches out or retraction electric knife head, described handle is being provided with light-emitting component near electric knife head one end, and handle is provided with the lighting button of controlling light-emitting component.

2. pencil according to claim 1, is characterized in that, is also provided with two button electrodes on described handle, a kind of mode of operation of two each control electrodes of button electrode.
