Description
Technical field
The utility model relates to neurosurgery Minimally Invasive Surgery medical instruments fields, and in particular to a kind of for Minimally Invasive Surgery
Sleeve aspirator.
Background technique
When carrying out clinical operation under nerve endoscope, although wound is smaller, surgical procedure can inevitably cut to blood vessel, out
Existing local hemorrhage, pricking resistance blood method with traditional line is not just very applicable in endoscopic surgery, therefore is answered in clinic
It is widely adopted with the method for electric coagulation hemostasis.
Coagulation originates from very early for surgical hemostasis, and the electric current for operation is high-frequency current (frequency per second thousands of thoughtful 2,000,000
More than week).Using high-frequency current, even if voltage is up to thousands of volts, also can safety human body, do not cause nerve or muscle it is anti-
It answers.Using the fuel factor of high-frequency current, make vascular wall dehydration shrinkage, vessel inner blood solidification, and melts blood vessel mutually with blood clot
It is integrated, and reaches effectively hemostasis purpose.
So far cautery or electric knife have become one of standing instrument of operating room.Electric coagulating apparatus system uses oscillating tube or spark gap
Electric discharge device come generate operation needed for high-frequency current.It initially applies and so far still by common coagulation method for " monopole is electric
It is solidifying ", i.e., the biggish metal plate of an area is contacted with patient posterior as one of electrode, referred to as patient electrode or dispersing electrode；
Another electrode has then connect coagulation effect, referred to as procedures electrode or active electrode with hemostatic device.Use electric current when monopolar coagulation
By patient body, the size of fuel factor depends on the size of electrode and bodily tissue contact surface, i.e. unit area current amount
The size of (current density) is inversely proportional with contact area size.The metal plate of dispersing electrode and body access areas are very big, unit
The magnitude of current of area is very small, therefore burns and act on without heat to tissue.Active electrode be used for when stopping blooding or cutting and the contact surface of tissue very
Small, current density is very big, then generates the bright hemostasis of heat or dissection.Monopolar coagulation can also with a variety of surgical instruments such as haemostatic clamp,
Tweezers, aspirator, scalpel or steel wire snare etc. contact and play the multiple uses such as hemostasis or cutting；But its electricity demand is big,
Thermal diffusion range is big, larger to surrounding tissue damage, is still seeing change in organization, thus monopole electricity apart from 1 centimeters of cutting
It coagulates near significant points such as function of cortex area, important blood vessels and brain stem, spinal cord, nerve root etc. should not be applied.
Early in 1940, it is with the difference of monopolar coagulation to eliminate contacted with patient posterior for the appearance of bipolar coagulation
Dispersing electrode, and two electrodes are connect respectively on two blades of a tweezers, it is insulation between two blades of this tweezers.It answers
Used time electric current only passes through the tissue between two tip of tweezers, therefore institute's electricity demand is greatly reduced, and generally only needs the 1/4 of monopolar coagulation to arrive
1/3, electricity can even be reduced to 1/10 not as good as monopolar coagulation, thus the diffusion of heat when stopping blooding in significant points such as spinal cord
Reduction corresponding with neighbouring damage.In addition, bipolar coagulation is with the presence of liquid such as physiological saline, cerebrospinal fluid or blood the case where
Under, coagulation anastalsis can be similarly played, this is also less than monopolar coagulation.
But during practical minimally-invasive treatment, medical staff one holds bipolar coagulation, in addition needs to hold scope on the other hand
And aspirator, surgical procedure are very inconvenient.
Utility model content
To solve the above-mentioned problems, the utility model discloses a kind of sleeve aspirators for Minimally Invasive Surgery, this is practical
New structure is simple, and design is scientific and reasonable, can be to hold multiple medical instruments in effective solution medical staff's surgical procedure
Problem improves the accuracy and success rate of operation.
The technical solution of the utility model includes:
It is proposed a kind of sleeve aspirator for Minimally Invasive Surgery, including negative tube, scope and connector；The negative tube is logical
It crosses connector and scope is installed as parallel overall structure；One end of the negative tube successively with for control three-way interface and
Negative pressure pump connection；The connector generally " cuboid " shape；The both ends of the connector are equipped with for fixing negative tube and interior
The semicircular opening of mirror；Rotating wheel is additionally provided between two semicircular openings inside the connector；The one side edge of the rotating wheel
Be embedded into the inside for installing the semicircular opening of fixed negative tube, the negative tube by rotating wheel can in mounted situation with
Scope carries out relative displacement activity；The connector is additionally provided with the back springing type limit switch for controlling rotating wheel, wherein limiting
Spring is equipped between switch and rotating wheel.
The general plotting of the utility model: medical staff generally requires a hand-held bipolar electric when carrying out Minimally Invasive Surgery
Solidifying to stop blooding, in addition a hand then needs to hold negative tube and scope simultaneously, and the installation of negative tube and scope passes through connector
To be realized.Sleeve aspirator includes negative tube, scope and connector, and negative tube is mounted on one by connector and scope
It rising, medical staff is when operation, when situations such as observing bleeding, smog from the mating computer screen of scope, medical care
Personnel only need fixed point location to carry out manipulation vacuum suction, as long as and observing such case, energy in computer screen
Vacuum suction is carried out in first time, it is convenient, fast, accuracy is high.The functional diversities of connector, not only can be according to actual
Scope visual field demand adjusts the length difference of negative tube and scope, and the semi-circular opening of connector more saves space, dismounting
Simply.
Further, the connector is additionally provided with and matching used " L " the type chuck of limit switch, the design of " L " type chuck
It can play the role of control switch with limit switch.
Further, it is additionally provided with the loudspeaker opening for easy disassembly at the semicircular opening at the connector both ends, facilitates peace
Dress and disassembly.
Further, the port section negative tube of the sleeve aspirator is longer than scope, in this way can to avoid endoscope lens with
Operative site contact.
Further, the length of the connector is 1-2cm, width 0.5-1.5cm.
The utility model has the beneficial effects that
1, it when situations such as observing bleeding, smog from the mating computer screen of scope, can born at the first time
Pressure attracts, convenient, fast, accuracy is high.
2, the functional diversities of connector not only can adjust negative tube and scope according to actual scope visual field demand
Length difference, and the semi-circular opening of connector more saves space, and dismounting is simple.
3, the utility model structure is simple, and design is scientific and reasonable, can be with hand in effective solution medical staff's surgical procedure
The problem of holding multiple medical instruments improves the accuracy and success rate of operation.
