Abstract
The utility model discloses a kind of pencil, comprise handle, electric knife head and electrode, electric knife head is the tubular structure of hollow, and electric knife head is connected to the leading section of handle, is connected with sheath at the front port place of electric knife head, sheath is the hollow structure of open at both ends, sheath one end is provided with external screw thread, and the other end is provided with female thread, and electric knife head front port is provided with female thread, sheath one end and electric knife head are spun by screw thread, and the sheath other end is connected with block by threaded engagement.This utility model can effectively prevent electrode in the damaged in collision of not used time and pollution by arranging block; Sheath is set at electric knife head end, the length of exposure that can need according to electrode in actual operation operation, carries out suitable adjustment by the length that spins of adjustment sheath and electric knife head, prevent from operation process, damaging other No operation position.
Description
Technical field
This utility model belongs to surgical operating instrument field, particularly relates to a kind of pencil.
Background technology
Pencil arrives tissue of patient by making radio-frequency current pass electrode, and the position of patient's circular arc electrode contact is heated rapidly by radio-frequency current, can carry out cutting, blood coagulation, drying or burn operation, and operative site produces thermocoagulation fast, can reduce operative hemorrhage.Existing pencil generally includes handle and motor, and what electrode was fixing is arranged 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 operationally, and careless slightly electrode will encounter the No operation position of patient by mistake, causes damage to patient, even can cause malpractice, especially be difficult to especially avoid in the occasion that operative space is narrow and small.In addition, the consistent naked leakage of electrode outside, is easy to be collided and damage, and very unhygienic.
Summary of the invention
In order to overcome problems of the prior art, the purpose of this utility model is to provide a kind of pencil.
In order to realize foregoing invention object, this utility model adopts technical scheme as described below:
A kind of pencil, comprise handle, electric knife head and electrode, electric knife head is the tubular structure of hollow, and electric knife head is connected to the leading section of handle, is connected with sheath at the front port place of electric knife head, sheath is the hollow structure of open at both ends, sheath one end is provided with external screw thread, and the other end is provided with female thread, and electric knife head front port is provided with female thread, sheath one end and electric knife head are spun by screw thread, and the sheath other end is connected with block by threaded engagement.
Further, the end face of the sheath other end is embedded with light-emitting component, light-emitting component is electrically connected with the power supply be arranged on handle and gauge tap.
Owing to adopting technique scheme, this utility model has following superiority:
1, can effectively prevent electrode in the damaged in collision of not used time and pollution by arranging block;
2, sheath is set at electric knife head end, the length of exposure that can need according to electrode in actual operation operation, carries out suitable adjustment by the length that spins of adjustment sheath and electric knife head, prevent from operation process, damaging other No operation position;
3, by arranging light-emitting component, making operative site clearly, being convenient to the exact operations of performing the operation, improve operation safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-hands handle; 2-electric knife head; 3-sheath; 4-blocks a shot; 5-electrode.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of pencil, comprises handle 1, electric knife head 2 and electrode 5, the tubular structure of electric knife head 2 in hollow, electric knife head 2 is connected to the leading section of handle 1, be connected with sheath 3 at the front port place of electric knife head 2, sheath 3 is the hollow structure of open at both ends, and sheath 3 one end is provided with external screw thread, the other end is provided with female thread, electric knife head 2 front port is provided with female thread, and sheath 3 one end and electric knife head 2 are spun by screw thread, and sheath 3 other end is connected with block 4 by threaded engagement.
In addition, in order to increase the safety of operation process, the end face of the sheath other end is embedded with light-emitting component, light-emitting component is electrically connected with the power supply be arranged on handle and gauge tap.
This utility model can effectively prevent electrode in the damaged in collision of not used time and pollution by arranging block; Sheath is set at electric knife head end, the length of exposure that can need according to electrode in actual operation operation, carries out suitable adjustment by the length that spins of adjustment sheath and electric knife head, prevent from operation process, damaging other No operation position.
