Description
Technical field
The present invention relates to Medical Devices or medical instrument, specifically a kind of scalpel with minute-pressure air-flow.
Background technology
With the development of science and technology, many operations can be realized by Minimally Invasive Surgery, but still there is most operation
It is to need traditional scalpel.For surgical operation, after loose connective tissue gap is exposed in art, layer of performing the operation
The selection in face is most important, conventional use of electric knife, and the surgical instruments such as ultrasound knife or Ligasure no doubt have the excellent of its own
Point, but be exactly the surgical plane for being easily accessible mistake the problem of its maximum, so as to which internal organs be caused to be damaged, cause postoperative appearance serious
Complication, some even can be dead.In addition, if scalpel enters the surgical plane of mistake, important blood vessels are easily damaged, are made
Even occurs the situation that can not be retrieved into Massive Bleeding.And for the young surgeon of lack of experience, then it is easier to occur
This problem.
Invention content
The purpose of the present invention is exactly of the existing technology to solve the problems, such as, and is devised a kind of with minute-pressure air-flow
Scalpel can comb the loose connective tissue of surgical plane position with air-flow in operation so that surgical plane is more
It is clear accurate to add, and improves the accuracy of operation, considerably reduces in operation and the risk of error occur.
The technical scheme is that：A kind of scalpel with minute-pressure air-flow, cutter hub and handle of a knife including plug-in type, institute
Handle of a knife is stated equipped with fumarole, the fumarole is arranged on the both sides of cutter hub；The fumarole is connected to knife by unicom pipeline
The tail portion tracheae of handle；Heating unit is equipped at the fumarole；The tail portion of the handle of a knife is also associated with electronic controller；The electricity
Sub-controller be internally provided with microprocessor for connect control handle of a knife inside heating unit and fumarole air-flow.
The electronic controller is equipped with the button for adjusting temperature and flow parameter；The electronic controller is included certainly
Dynamic control model and MANUAL CONTROL mode.
When the electronic controller is automatic control mode, microprocessor starts the temperature sensing set in connection fumarole
Device and air velocity transducer, and the control damper on microprocessor electrical connection heating unit and tail portion tracheae.
When the electronic controller is MANUAL CONTROL mode, microprocessor is in standby mode, and gas ejecting system passes through setting
Manual flow flow knob and manual temperature control handle above handle of a knife control.
It is described that the adjusting tabletting for adjusting jet direction is internally provided in fumarole, it is equipped with and adjusts at the lower section bottom surface of the handle of a knife
Save idler wheel.
The adjusting tabletting is fixed on by the shaft of side in fumarole, and the opposite side for adjusting tabletting passes through connection
Bar is connect with adjusting idler wheel.
Preferably, the heating unit is electric-heating-wire-heating device, heating temperature is controlled by the size for controlling electric current.
Stability during in order to increase hand-held in use, the surface of the handle of a knife are equipped with skid resistance strip.
It is fixed preferably, the cutter hub is plugged on handle of a knife by two bolts.
In order to ensure the cleaning of air source and stabilization, the tail portion of the handle of a knife is connected with sterile air source by tracheae, passes through
It is continuous to be blown into aseptic gas, while germ-free condition is kept to play certain protective effect scalpel.
This programme can set automatic control mode by electronic controller, under automatic control mode, by the micro- of inside
Reason device is controlled according to parameter set in advance, has temperature sensor and air velocity transducer inside handle of a knife to monitor in real time anti-
Feedback keeps spraying the temperature and flow of gas.Manual mode can be switched to simultaneously, can more have and targetedly be adjusted
Section is suitble to different type of surgery.
Beneficial effects of the present invention can obtain through the above scheme：It is filled by setting jet upper on the handle of a knife by scalpel
It puts, operation consent side can be impacted using the gas stream that fumarole ejects, generate a kind of drawing effect, make scalpel
There is higher tension between the connective tissue in front, break through these loose connective groups using the light pressure that gas stream is formed
Knit gap so that operation level is more clear.It avoids and goes to detach these tissues using artificial instrument, so as to ensure that operation
Level it is correct.In addition, being equipped with heating unit at spray-hole, the gas stream ejected can be made to reach certain temperature,
For the capillary oozing phenomenon occurred during separation connective tissue gap, blood clotting in blood vessel can be made to one
Fixed depth, so as to reduce patient's intraoperative hemorrhage.Adjusting idler wheel is equipped in the lower section of handle to use when grips said handle
The middle finger for holding handle carries out scroll forward and backward, to adjusting tabletting control to adjust the direction of air-flow using connecting rod, can make
Concentration or the dispersion of air-flow are obtained, adapts to the surgical environments such as muscle, the connective tissue of different parts, and can coordinate and perform the operation
The volume of the state of an illness needs to change stream condition at any time in journey, and the stabilization for operation carries out providing sound assurance.Scalpel simultaneously
Installation, the dismounting of piece are very convenient, and knife blade is connected firmly, reliably, and a kind of good surgical instrument is provided for doctor.
This programme can greatly improve success rate of operation, and operating time is greatly shortened, and reduce the generation of postoperative complications.For disease
People, is very good selection for surgeon, and application prospect is very wide.
It can be seen that the present invention has substantive distinguishing features and progress compared with prior art, the advantageous effect implemented
It is obvious.
