Description
Technical field
The invention belongs to the field of medical instrument technology, and comprehensive drawing means for brain tissue is adjusted more particularly to one kind.
Background technology
Traditional brain tissue retracts and the foundation of operation path utilizes the dissection knot of cranium brain mainly by brain spatula by human hand
Structure retracts brain tissue, relies primarily on the professional skill and experience of patient.And it be easy to cause brain during brain tissue is retracted
The damage of blood vessel and nerve, brain retraction injury are seen everywhere, and due to the creep characteristic of brain tissue after traction, the channel expanded is easy
Contraction becomes smaller, and influences surgical procedure.Directly being retracted using brain spatula needs larger bone window to be operated, and wound is big,
Easily infection, patient's recovery time is long, and very big pain and heavier financial burden are brought to patient.And existing brain spatula is usual
It for stainless steel substrates, lacks flexibility, and hardness is higher, it applies brain tissue certain pressure during due to operation, and control is improper very
Easily cause the illnesss such as brain edema, cerebral contusion, cerebral infarction and cerebral hemorrhage, new damage is caused to patient.
A kind of antisitic defect brain spatula disclosed in patent No. CN201520286994.8, including brain spatula plate body, sets on plate body
There are scale mark and pressure sensor, plate body is coated with soft protective layer.Easily carry out cerebral surgery operation and need into
When row brain tissue pulls, after pulling brain tissue using brain spatula, doctor can be according to scale mark and pressure sensing thereon
Device, is adjusted its insertion depth and drawing dynamics, effectively avoids causing brain due to the too deep or traction force of insertion spends big
Tissue damage.In addition, by covering one layer of soft antibiotic layer outside brain spatula plate body, can effectively avoid because of cerebral plate material
The damage really up to the mark caused by brain tissue.A kind of novel brain spatula of neurosurgery disclosed in patent No. CN201420620545.8,
Including pressing plate ontology, the front end position of the pressing plate ontology sets embedded air bag, the embedded air bag and pressure inductor
Contact, the pressure inductor connect by conducting wire with inductive signal lamp, minicell successively, the pressure inductor, described
Minicell and the inductive signal lamp are arranged in the pressing plate ontology.It at the front end position of pressing plate ontology by setting
Embedded air bag, the embedded air bag are contacted with pressure inductor, the pressure inductor successively with inductive signal lamp, miniature
Battery connects, and realizes and facilitates control to brain spatula pressure；Embedded air bag is contacted with human body brain, when medical staff presses
Afterwards, pressure inductor senses the pressure of embedded air bag, when pressure be more than safety value after, inductive signal lamp i.e. and micro power
It connects, at this point, inductive signal lamp flickers, medical staff is prompted to pay attention to pressing excessive, the flicker of inductive signal lamp also allows for medical care
The observation of personnel.
The use of pressure sensor in above-mentioned patent, when realizing brain spatula traction brain tissue, the traction pressure of brain spatula
It is adjustable, but when brain spatula retracts brain tissue, need to be retracted by multiple brain spatulas, cause it is time-consuming and troublesome in poeration, and cannot 360
Degree retracts, and brain spatula may cut brain tissue and cause to damage.In addition, drawing means for brain tissue is fixed for existing size, no
Can brain channel freely be adjusted according to operation demand and retract size；It causes initial brain channel must be big as retractor, necessarily makes
It removes or retracts excessive so as to cause compared with macrolesion into brain tissue.
Invention content
The purpose of the present invention is that having overcome the deficiencies of the prior art and provide a kind of operation path that can freely adjust retracts
Size, it is small to brain tissue impairment, and 360 degree of tractions, the comprehensive brain tissue that is adjusted of brain tissue cutting damage will not be caused to lead
Open device.
To achieve these goals, the present invention provides one kind to be adjusted comprehensive drawing means for brain tissue, including sleeve group
Part and skeleton, the sleeve assembly include handle and inner cylinder, the inner cylinder upper end opening, and lower end closed and hemispherical is described
The lower end of inner cylinder is provided with several small through hole, and the small through hole penetrates through the inside of the inner cylinder with external, and the handle is fixed on
The outer surface of the inner cylinder upper end, the skeleton include skeleton ring and spiral spring, successional card are provided on the skeleton ring
Slot, the head end of the spiral spring are fixed on the skeleton ring, and the end of the spiral spring and the head end of the spiral spring are in
The same end, the end of the spiral spring are in active state relative to the skeleton ring, and the inner cylinder is inserted into the spiral shell of the skeleton
In the rotation spring and lower end of the inner cylinder is pierced by the spiral spring, and the size of the spiral spring is caught in the end of the spiral spring
Become larger or reduce in the card slot of the different location of the skeleton ring, the surface of the spiral spring is attached with transparent elastic material
The bed of material.
Further, the outer diameter of the inner cylinder is less than or equal to 2cm.
Further, the end of the spiral spring is passed through from the threaded interior of the spiral spring to the head of the spiral spring
End, the head end of the spiral spring are fixed in the circle of the skeleton ring, and the end of the spiral spring leans against the circle of the skeleton ring

In the card slot of different location that the end of rotation spring is caught in the wave circular arc, the size of the spiral spring accordingly becomes larger or contracts
It is small.
Further, several small through hole are distributed setting along the lower circumferential of the inner cylinder.
The inner cylinder of sleeve assembly of the present invention is placed in the spiral spring of skeleton, and the lower end of inner cylinder is pierced by spiral spring, the present invention
Preferably, the most initial shape of spiral spring is cylindric, and the outer diameter of inner cylinder is less than or equal to 2cm, and interior cylinder size is small, i.e. spiral spring
Size is small during original state.The present invention is oriented to inner cylinder and spiral shell by inner cylinder lower end in use, clamp handle by clamping device
Rotation spring is led together into brain tissue, and the original state that the present invention is in minimum dimension with spiral spring is led into brain tissue, to realize this hair
It is bright to be in minimum state in size and lead into brain tissue comprehensive traction brain tissue again, brain tissue is protected to greatest extent.It leads
After opening brain tissue, inner cylinder is taken out, so as to establish operation path.The end of spiral spring is caught in by skeleton ring according to operation demand at this time
Different location card slot in, so as to freely adjust the size of spiral spring, so as to freely adjust the size of operation path, avoid showing
Some sizes fix drawing means for brain tissue, cannot freely adjust brain channel according to operation demand and retract size；Cause initial brain
Channel must be big as retractor, and brain tissue is necessarily caused to remove or retract excessive so as to cause compared with macrolesion.In addition, this hair
Bright is adjusted comprehensive drawing means for brain tissue as 360 degree of tractions, will not cause brain tissue cutting damage, break away from existing brain spatula
It when retracting brain tissue, need to be retracted by multiple brain spatulas, cause time-consuming and troublesome in poeration, while cause brain tissue cutting damage.
Layer of transparent elastic material is attached on the spiral spring of the present invention, layer of transparent elastic material will not cause to damage to brain tissue
Wound, with the end that spiral spring is effectively ensured is caught in the different location card slot of skeleton ring and adjusting size will not to retract brain tissue
Brain tissue is caused to damage.
