Background technique
Disposable coagulation cutter is widely used in clinical operation, its working principle is that using high-frequency current to part
The concentration fuel factor of biological tissue makes tissue or structural constituent vaporize or burst, to reach the medical operatings such as solidification or cutting
Purpose.Existing disposable coagulation cutter has some shortcomings in actual use: (1) electrode is in coagulation cutter
Regular length, the coagulation cutter rotation that when operation may need to be equipped with more different sizes uses, to increase cost.(2)
Itself do not have illumination functions, need to be illuminated during operation by exterior lighting equipment, and when performing the operation as deep operation or
When art portion is human body natural cavity deep, the light from exterior lighting equipment cannot obtain satisfied illumination, or may be by coagulation
Cutter or other instruments are stopped, and illuminating ray is caused to be difficult to reach visual area.
Summary of the invention
In view of the above problems, the object of the present invention is to provide the disposable coagulation cutters that a kind of length can be changed.
To achieve the above object, the utility model uses a kind of following technical scheme: disposable coagulation cutter, comprising:
The hollow edged electrode of the shell is stretched out in shell in a tubular form, front end, and the electric knife of the hollow edged electrode front end is arranged in；Institute
It states the external of hollow edged electrode and coats insulation sleeve；It is characterized by also including telescoping tubes and rotational adjustment member；Wherein, described to stretch
The draw includes core pipe and casing, and the rear end of described sleeve pipe is cooperatively connected by the front end of internal screw thread and the core pipe；The rotation
Regulating member is annular and the rear end for being rotatably connected on the shell, and the rotational adjustment member passes through connection sheet and the core pipe
Outer wall be fixedly connected；Be fixedly installed sliding block on the outer wall of described sleeve pipe, the sliding block be slidably arranged at be provided with it is described
In sliding slot in inner walls, the sliding slot extends along the length direction of the shell；The front end of described sleeve pipe and the tubulose
The rear end of electrode is fixedly connected.
Further, it is equipped with the supporting member in cylindrical shape in the inside of the hollow edged electrode, in the support structure
Run through the channel of front and back there are three being arranged on part, arrange medical optical fiber in the first channel or LED light be set in Channel front end,
Camera is arranged in second channel, arranges Medical suction unit in third channel.
Further, insulation sleeve is also coated in the outside of the supporting member.
Because the utility model adopts the above technical scheme, it has the following advantages: 1, the utility model can pass through rotation
Turn the length that regulating member stretches out shell to hollow edged electrode to be adjusted, makes its rotation when applying torque to rotational adjustment member
When, rotational adjustment member drives core pipe to rotate by connection sheet, and the rotation of core pipe is transported by the straight line that screw thread pair is converted into casing
It is dynamic, to realize the stretching and recycling of hollow edged electrode, the primary of plurality of specifications is needed in primary operation it is possible thereby to improve
The status of property coagulation cutter.2, the utility model wears supporting member in the inside of hollow edged electrode, is arranged on supporting member
Three channels, three channels are respectively arranged medical optical fiber (or LED), camera and Medical suction unit；Medical optical fiber or LED are used for
Art portion is illuminated when operation, and since illuminating ray is directly issued from hollow edged electrode front end, illuminating ray can
Art portion go directly without being blocked；Camera can advanced optimize surgical field of view, even in human body natural's cavity and deep
It performs the operation, also can observe in real time surgery situation and can recorde, retaining and share convenient for operation evidence；Medical suction
Device can attract the liquid and smog generated during operation, guarantee the cleaning of surgical procedure, and avoid blood pair
Observation sight causes obstacle.3, anti-skid chequer is arranged in the external of shell in the utility model, can increase hand-held stability.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the overlooking structure diagram of Fig. 1；
Fig. 3 is the schematic diagram of internal structure of the utility model；
Fig. 4 is the cross-sectional view of the utility model supporting member.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Figures 1 to 3, the utility model includes: shell 1 in a tubular form, and the hollow edged electrode 2 of shell 1 is stretched out in front end, with
And the electric knife 3 of 2 front end of hollow edged electrode is set.External in hollow edged electrode 2 coats insulation sleeve (not shown).Its feature exists
In: it further include telescoping tube 4 and rotational adjustment member 5.Wherein, telescoping tube 4 includes core pipe 6 and casing 7, and the rear end of casing 7 passes through
The front end of internal screw thread and core pipe 6 is cooperatively connected.Rotational adjustment member 5 is annular and the rear end for being rotatably connected on shell 1, and rotation is adjusted
Section component 5 is fixedly connected by connection sheet 8 with the outer wall of core pipe 6.Sliding block 9, sliding block 9 are fixedly installed on the outer wall of casing 7
It is slidably arranged in the sliding slot 10 being provided on 1 inner wall of shell, sliding slot 10 extends along the length direction of shell 1；The front end of casing 7
