Description
Technical field
The invention belongs to ophthalmic surgical medical instruments fields, and in particular to a kind of surgical operation is dissected in scalable art
Device.
Background technique
Dissector, that is, electric knife-pen of surgical operation is the surgical operating instrument for carrying out surgical tissue cutting.Electric knife-pen is
Electrode is passed through by high-frequency current and reaches destination organization, and the destination organization position mutually close with electrode is heated rapidly by high-frequency current
The function of cutting, blood coagulation is realized in gasification by the variation of high-frequency current.It is out at present in section's operation, due to cutting the depth of tissue
Degree is different, needs the electrode of different length, and when specific operation, doctor can use the electric knife-pen of different length electrode, and switching trouble is more
A electric knife-pen causes the waste of resource；And electrode replacement is inconvenient in existing electric knife-pen, as electrode is divided into electric hook, torch, electricity
Knife, power shovel and acusector, using multiple electric knife-pens are just needed when a variety of electrodes in operation, use is very inconvenient.
Summary of the invention
It is dissected the object of the invention is that providing a kind of surgical operation to solve the above-mentioned problems in scalable art
Device, using the relative motion of nut knob and telescopic rod, to realize the accurate movement of telescopic rod, not due to wound depth difference
Greatly, accurately adjust and be conducive to accurate cutting of the electrode to destination organization, and the dissector also have Image Acquisition, illumination,
It smokes, be conveniently replaceable the function of electrode, it is easy to use.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of surgical operation dissector in scalable art, including shell, telescopic rod and electrode are designed, which is cavity
Structure, and the shell includes shell, the housing upper surface forms key boss, and lower surface forms friction boss, front end
Form installation base；And control circuit board is installed, in the cavity of the friction boss in the cavity of the key boss
The getter device being electrically connected with control circuit board is installed, is equipped in the cavity of the installation base and is electrically connected with control circuit board
The ccd image collector and headlamp connect；
The telescopic rod is laterally arranged along the cavity structure of shell, and in the top level for deviateing the shell of the telescopic rod
Heart line, the telescopic rod includes integrally formed threaded joints and limit sliding part, wherein the threaded joints screw thread connects
It is connected to nut knob, which stretches out the upper surface of the shell；The limit sliding part is cuboid block, the cavity
Front and back is each provided with a longitudinal support plate in structure, and cuboid block is horizontal through two support plates, and the front end of cuboid is slided
It is fitted in the electrode mounting hole of the installation base；The front end of the cuboid offers cylindrical card slot, the card slot
Inner wall on be provided with contact flat spring, contacted in the electrode insertion card slot with contact flat spring, the contact flat spring passes through conducting wire
It is electrically connected with control circuit board；When adjusting telescopic rod, rotating nuts knob simultaneously passes through relative limit before and after nut knob, the length
Cube block relative support plate circumference is to limit, so that the telescopic rod can be elastic, adjusts the length of electrode；
The getter device is connected with smoke extracting tube and smoke exhaust pipe, wherein the smoke extracting tube passes through the support plate of cavity structure front simultaneously
The front end of the smoke extracting tube is fixed in the smoke extracting tube mounting hole on installation base, and the front end of the smoke extracting tube is also connected with tubaeform
Smoking mouth；The support plate that the smoke exhaust pipe passes through cavity structure rear portion extends to the outside of shell.
Using above technical scheme, key boss is equipped with multiple keys connecting with control circuit board, is pressed by multiple
Key can control the work of ccd image collector, headlamp respectively, and can control contact flat spring by key and be powered；?
When surgical procedures, can according to the depth of destination organization, adjusting nut knob, at this point, nut knob only makes rotating motion,
And the cuboid block of telescopic rod is with front and back support plate due to being slidably matched, the perforation of support plate limits the rotation fortune of telescopic rod
It is dynamic, so that nut knob and being threadedly engaged for telescopic rod can be such that telescopic rod alongst moves, the stretching of coordination electrode
Length, and the design structure makes telescopic rod position deviate the center line of shell and offsets up, it in this way can be in tilt operation
When avoid installation base contact human body, provide bigger operating space, and be capable of providing the position of installation smoke extracting tube；It will
It is to contact the cigarette generated with destination organization in order to avoid electrode to float block upwards that smoke extracting tube, which is arranged in below electrode installation site,
The sight of doctor, smoke extracting tube takes the cigarette of generation away under the action of getter device below electrode, and tubaeform smoking
Mouth can also increase the efficiency of smoking, easy to use；
And the replacement for electrode, electrode include connecting rod and electrode tip, electrode tip is by a variety of, such as electric hook, torch, electric knife, electricity
Shovel and acusector also have the replacement structure for facilitating electrode using card slot in the prior art, but card slot is arranged on shell, and only
The poor contact of electrode is caused using card slot, it may appear that the unstable phenomenon of electrode frequency, by card slot design flexible in this case
