Description
Technical field
The invention belongs to medical instruments fields, are specifically related to a kind of scalpel in intervertebral disc operation.
Background technique
Protrusion of lumber intervertebral disc is clinically relatively conventional one of lumbar disease, is common disease, the frequently-occurring disease of orthopedics and traumatology, master
If having different degrees of degenerative change because of lumber ertebral disc each section (nucleus pulposus, fibrous ring and cartilage plate), especially nucleus pulposus
Afterwards, under the action of extraneous factor, the Anular disruption of interverbebral disc, nucleus pulposus is from rupture place prominent (or abjection) in rear
Or intraspinal tube, cause adjacent tissue, such as spinal nerve root, spinal cord to be stimulated or oppressed, so that flank pain is generated, side
A series of clinical symptoms such as lower limb or double lower limb numbness, pain.
The most common symptom of patients with lumbar disc herniation is pain, can behave as lumbago, sciatica, typically
Sciatica is shown as by buttocks, thigh rear side, small leg outer side to heel or the Rediating Pain on instep.According to clinical statistics, about 95%
Waist dash forward disease patient have different degrees of pain in the loins, 80% patient has melosalgia.Especially pain in the loins is not only protrusion of lumber intervertebral disc
One of most common symptom, and the symptom occurred earliest.So clearly examining if it find that there is similar situation that should go to a doctor in time
It is disconnected, the possibility of other factors is excluded, is gone through, to prevent failing to pinpoint a disease in diagnosis, avoid delay the state of an illness.Some patients are not diagnosing correctly
Under, blind therapeutic interest loses best occasion for the treatment.Effective treatment regular in time is very crucial after making a definite diagnosis, clinical
The method of upper treatment protrusion of lumber intervertebral disc has very much, such as operative treatment, physical therapy, medicinal treatment, drawing method, manipulation etc.
Deng.
Operative treatment is to carry out open operation to patient to eliminate interverbebral disc outstanding, to achieve the purpose that healing.Emphasis
Key is to release nerve root irritation or compressing, eliminates neuroinflamation, promotes neural restoration etc., its main feature is that quick.But need
Although should be noted that operative treatment significant effect, costly, risk is big, because often difficulty is very big for such operation, danger
It is dangerous high, and wound is larger, usual the convalescence after Miles operation is 3 months, the serious working and learning life for affecting patient, more
There is the stability for notably influencing whether backbone, and there is the formation fibrous scar tissues such as infectivity, neurotrosis, neural fascia,
Make adhesion of nerver root, cause " recurrence pain " and lumbar stability poor, cause chronic back pain, change of weather reflection aggravates
Etc. sequelae.
Just because of above-mentioned problem, clinically the operative treatment of protrusion of lumber intervertebral disc has stringent adaptation symptom: pain
Pain acutely, cannot be alleviated really by long-term non-operative treatment；Disc herniation object is larger or adhesion, calcification cause lateral crypt,
Spinal canal stenosis (fleshes such as non-hypertrophy of ligamentum flavum are narrow) is serious；Under blood vessel blood supply disorder is caused after nerve root irritation or compressing
The atrophy of limb muscle committee, muscular strength are decreased obviously significantly.
From the above, it can be seen that the operative treatment difficulty of protrusion of lumber intervertebral disc is very big, influenced caused by patient also greatly.Though
So there is significant therapeutic effect, doctor and patient also have to such operation of careful attention.Existing cutter is mostly cambered blade
Or zigzag cutter head.When operation, it is all made of general neural probe and auxiliary instrument appears interverbebral disc outstanding, after appearing sufficiently,
Lumbar intervertebral disc protrusion is cut with stylet annular again, voluntarily nucleus pulposus clamp takes out.It is careless slightly due to being close to spinal cord and nerve root, just
Possible injuring nerve causes irremediable consequence.If the success rate of operation can be improved effectively, reducing may in operation
Existing risk, operative treatment are clearly to treat the most effective means of protrusion of lumber intervertebral disc.
Summary of the invention
Goal of the invention: a kind of in intervertebral disc operation present invention aims in view of the deficiencies of the prior art, providing
Peeling knife reduces the operation difficulty of hernia of lumbar intervertebral disk, improves procedure efficiency, and be capable of the mind of effective protection operative site
Through and perienchyma.
Technical solution: intervertebral disc operation peeling knife of the present invention, including knife handle and cutter head, the cutter head are opened by side
The blade of sword is made along the curling of cutting edge position, and in the shape of a spiral, blade is located at the center of spiral in the section of cutter head, and the outer ring of spiral is made
For knife spine；The top of cutter head is connect with the knife handle, and the knife handle is cylindrical-shaped structure, and the diameter of knife handle is greater than the cutter head
Spiral radius of curvature maximum value, limit depth line of the lower end of the knife handle as the cutter head.
Further preferably technical solution is the present invention, has a columnar inner cavity in the knife handle, the cutter head
Top is protruded into the inner cavity, and the locking device by being arranged on the knife handle outer wall is locked.
Preferably, the top of the knife handle is additionally provided with one and turns cap, described to turn to rotate between cap and knife handle by shaft
Connection, the knife handle are freely rotated along the shaft.
Preferably, the section of the cutter head is Archimedes spiral.
Preferably, the knife handle is fabricated from a flexible material.
Preferably, non-slip groove is additionally provided on the knife handle.
The utility model has the advantages that the cutter head of (1) peeling knife of the present invention uses sheet helical design, knife spine towards outside, blade inwards,
Cutter head protrudes into operative site when use, holds knife handle rotary cutter part and cuts off nucleus pulposus, the peripheral nerve of operative site and other
Soft tissue will not be contacted with blade, and operation risk is greatly lowered；The nucleus pulposus of excision is located at the inside of cutter head, and excision is dry
Only, and convenient for taking out, exempt cutter head or remaining instrument in traditional operation protrude into repeatedly operative site to patient's bring pain and
Hidden danger；In addition in the present invention diameter of knife handle be greater than cutter head spiral radius of curvature maximum value, knife handle can limit peeling knife
Rotary-cut depth improves operation precision, will not injure vertebra intrinsic nerve, further decrease the risk of operation；
(2) cutter head top of the invention is protruded into inside knife handle, can be adjusted the length of cutter head according to the difference of individual, be made
Cutter head depth design meets organization of human body feature, will not injure vertebra intrinsic nerve, further increases the precision of operation, reduces hand
Art risk；
(3) on the top of knife handle, setting turns cap in the present invention, turns to be rotatablely connected between cap and knife handle by shaft, operate
When, the rotation angle of instant peeling knife is big again, also can guarantee that the hand of performer remains the state for holding peeling knife, favorably
In performer to the accurate control of operation；And knife handle of the invention is fabricated from a flexible material, and non-slip groove is additionally provided on knife handle,
It can further ensure the control to peeling knife of performer；
(4) peeling knife of the invention has operation risk low operation receiveing person, and pain is small, and excision effect is good, efficient high
The advantages of, have for performer easy to use, quick, operator requires lower, and operating time is short, high-efficient advantage, comprehensive
For conjunction, it is able to solve most of technical problem in the operative treatment of current protrusion of lumber intervertebral disc, improves applying for operative treatment
Possibility is opened up, the advantage of operative treatment is highlighted.
