Technical field
The utility model relates to a kind of Medical Devices, more specifically, it relates to a kind of for implementing the electricity of hepatectomy
Dynamic liver pincers.
Background technique
When treating pernicious liver diseases, hepatectomy can be often taken.At present when implementing hepatectomy, relatively mostly use
CUSA is ultrasonic suction device.CUSA has vibration cutting, perfusion and attracts three parts composition.Its hollow titanium tube is shaken along longitudinal direction
Dynamic, when contacting hepatic tissue, parenchymal tissue is smashed to pieces, and hepatic tissue is separated, and salt water of the cell fragment through being perfused passes through again after rinsing
Hollow titanium tube sucks.Meanwhile tougher tissue such as blood vessel, bile duct are not easy to be shaken broken and remained, that is, utilize ultrasonic wave
Concussion crushes tissue, emulsifies, then absorbs through negative pressure and reach removal lesion tissue.But it is acted on while existing CUSA device
Area is smaller, needs point-by-point operation, and efficiency is lower, this makes the hepatectomy time very long, easily aggravates the work of medical staff
Make the pain of intensity and sufferer.The patent of invention of Publication No. CN107981913A disclosed a kind of novel on May 4th, 2018
Hepatectomy clamp suction device, including No. two jaw arms and attractor, side appearance of No. two jaw arms close to upper end
Face is fixedly installed with No. two toothed forceps clip pads, and the lower end outer surface of No. two jaw arms is fixedly installed with No.1 clamp ring, described
The side of No. two jaw arms is equipped with No.1 jaw arm, and a side external surface of the No.1 jaw arm close to upper end is fixedly installed with No.1
Toothed forceps clip pad, the lower end outer surface of the No.1 jaw arm are fixedly installed with No. two clamp rings, the No.1 jaw arm and two
Removable pin is equipped at position between number jaw arm.A kind of novel hepatectomy clamp suction device described in the utility model,
Equipped with attractor, universal suction tube and closed tube wheel, the tissue under clamp can be sucked out while clamped liver, and can will inhaled
Skirt places specified position, and the length of suction pipe can be adjusted according to use demand, brings better prospect of the application.But it should
Utility model only has the function of that attraction falls off hepatic tissue, can not be directly used in hepatectomy.
Utility model content
Active area is smaller while existing hepatectomy device therefor, and working efficiency is lower, so that hepatectomy
It is time-consuming and laborious, the working strength of medical staff and the pain of sufferer are easily aggravated, to overcome this defect, the utility model is provided
A kind of active area simultaneously is big, and work efficiency is high, accelerates hepatectomy process, reduces medical staff working strength, mitigates
The electronic liver of sufferer pain is clamped.
The technical solution of the utility model is: a kind of electronic liver pincers, including a pair of hinged caliper, on the sandwich serface of caliper
Equipped with multiple vibration mould groups and slot is absorbed, vibration mould group is spaced apart with slot is absorbed, and is equipped with vibration device, vibration in vibration mould group
Device is connect with a controller, is absorbed slot and is connected to negative pressure gas source.Liver is clamped with caliper when the utility model is used, vibrates mould
Group is contacted with liver, and vibration device generates the mechanical oscillation of appropriate frequency under control of the controller, and drives vibration mould group vibration,
Make hepatic tissue be broken under vibratory impulse to disintegrate and fall off.The tissue that falls off, watery blood, which flow into, absorbs slot, under the action of negative pressure by
Attract discharge.Relative to existing CUSA device, the utility model can large area clamp liver and be crushed, therefore have bigger
While active area, working efficiency is greatly improved, and accelerates hepatectomy process, reduces medical staff's working strength, mitigates
Sufferer pain.
Preferably, caliper includes clamp segments and lever piece, the cross section of clamp segments is in U-shape, and vibration mould group further includes vibration
Dynamic module case as one and vibrating body, vibration module case as one are erected in the U-shaped mouth of clamp segments, and vibrating body is slidably connected at vibration mould group
In box body, the front end of clamp segments is closed, and rear end is connected with slough tissue drainage tube, and slough tissue drainage tube and the negative pressure gas source connect
It is logical.The U-shaped cavity of clamp segments is connected to negative pressure gas source, is negative pressure gas flow channel, and then constitute the hepatic tissue drainage lumens that fall off.Vibrate mould
Group box body provides relative closure space, completely cut off vibrating body can with slough tissue, watery blood, while can be also vibrating body and vibration dress
Set offer installation support, it is ensured that vibration mould group works normally.
Preferably, the slot bottom for absorbing slot is maked somebody a mere figurehead in the U-shaped mouth of the clamp segments, absorbs to be evenly equipped on the slot bottom of slot and pass through
Pass to the through-hole of clamp segments U-shaped cavity.The hepatic tissue that watery blood can be held and be crushed more thoroughly by absorbing slot setting through-hole passes through, and is crushed not
Complete larger hepatic tissue, which can be delayed at, to be absorbed in slot, and the hepatic tissue passing away that prevents from falling off is blocked.
Preferably, the vibration device be electromagnetic vibrator, electromagnetic vibrator be fixed on vibration module case as one and with vibration
Kinetoplast contacts, and is electrically connected on electromagnetic vibrator and the controller, and controller is equipped with vibration frequency adjusting knob and amplitude adjusting knob.Electricity
Magnetic vibrator is vibration source, can be mechanical oscillation by electrical power conversion.Electromagnetic vibrator is integrated, standard product, in the market
It is easy to get, installs, using more convenient, acquisition can according to need by the adjusting of shake frequency adjusting knob and amplitude adjusting knob and meet need
The vibration intensity asked.
Preferably, caliper further includes pipeline box body, the fixation of pipeline box body is fitted on the lateral surface of the clamp segments, shakes
In dynamic module case as one insertion pipeline box body.Pipeline box body is used for the laying of pipeline, route, so that pipeline obtains properly shielding shield.
Preferably, vibrating body is equipped with cushion.Cushion can moderately reduce the rigidity on vibration mould group surface, when vibration
It prevents extruding, the vibration intensity of vibrating body excessive, avoids damaging blood vessel, the bile duct on liver.
The beneficial effects of the utility model are:
Hepatectomy efficiency is improved, medical staff's working strength is reduced.The utility model can large area clamp liver progress
Active area while being crushed, therefore have bigger, working efficiency are greatly improved, and accelerate hepatectomy process, reduce medical care
Person works' intensity mitigates sufferer pain.
