Description
Technical field
The present invention relates to a kind of medical operation devices, and in particular to a kind of way of escape canalis spinalis operation minimally invasive retractor of soft tissue.
Background technique
Cervical posterior approach is mainly posterior cervical enlargement of cervical canal, is exactly by the subsequent vertebral plate of spinal cord and tough plainly
Band from top to bottom, is opened from one or both sides, expands the space at spinal cord rear, and the compressing come from behind dissolves by itself, comes from
Although the compressing in front also exists, spinal cord can be hidden backward.Chinese patent CN 2075506U discloses a kind of Lumbar Vertebral Canal hand
Art exposing device, it is made of distraction plate and opening frame, and distraction plate is half arc shape, for convenient for being matched with opening frame, In
There is a grab to match with opening frame in the root of distraction plate handle, and opening frame is by frame body, slide plate, power pawl and struts bar and constitutes, frame
The overall structure that body is connected by two baffles, backplate and balance plate with grab.In use, only need to the grab of distraction plate and
Handle hook mutually blocks with the backplate of opening frame and the buckle of balance plate.It, be first by two power before operation starts upper distraction plate
Pawl is drawn close to middle slip, it is made to be attached to the two sides for strutting plate body, not only can influence sight to avoid bar is opened, but also can guarantee support
The force of opening lever focuses on distraction plate.The display device for lumbar vertebra operation does not need multiple medical staff while operation with exposure
Operative site, its own stable structure balance in power, are flexible operation, easy to use, improve procedure efficiency, avoid possibility
The additional pain caused by sufferer and so on.
But posterior approach has the following problems: 1, for the muscle ligament at cervical vertebra rear by extensive injuries, postoperative rehabilitation is difficult；
It is tightly fastened securely because muscle and ligament are contacted with cervical vertebra rear structure, the muscle ligament at rear can just play fixed maintenance neck
Centrum position, the effect for pulling moving cervical vertebra just must be by filling between muscle and ligament and sclerotin if to appear vertebral plate naturally
Divide connection separation.2, being related to fixation posterior approach more being fused to multiple segments, be affected to cervical vertebra moving, patient is postoperative
There is Wry Neck sense.3, the principle of cervical posterior approach is, in-migration after spinal cord hidden to the compressing in front, but spinal cord backward
In moving process, 5 nerve root of neck will receive drawing, and some patientss just will appear the injury symptoms of 5 nerve root of neck, such as shoulder pain
Bitterly.It is generally speaking, traditional that different degrees of damage is caused to soft tissue by vertebra through the decompression of posterior lumbar pipe and fusion,
Traditional operation opereating specification is big, and the tendon stop position of multifidus is removed extensively, and needs several medical cares in the course of surgery
Personnel operate simultaneously, for by operative site exposure, both waste of manpower and inconvenient for operation, and be easy to cause irreversible
Damage, brings unnecessary additional pain to patient.
In order to mitigate painful and postoperative recovery when sufferer operation, many operations all use Minimally Invasive Surgery, ridge at present
Also there is a kind of cervical vertebra Minimally Invasive Surgery (such as schwannosis, simple spinal cord, amputation) in column operation, does not often need to cut
Larger skin incision, such operative incision is small, bleeding is few, and operating time is short, and wound is relatively small, restores and healing time contracts
It is short, but traditional operative site exposure instrument can not be suitable for this Minimally Invasive Surgery, significantly limit minimally invasive spine surgical
Development.
Summary of the invention
In order to solve the above-mentioned operative site exposure instrument etc. for not being specially adapted for existing posterior cervical Minimally Invasive Surgery
Problem, the present invention provides a kind of way of escape canalis spinalis operation minimally invasive retractor of soft tissue, concrete scheme is as follows:
A kind of way of escape canalis spinalis operation minimally invasive retractor of soft tissue, including two hinged linking arms, the connection
The both ends of arm are separately formed as working end and handle end, and the working end of two linking arms, which is equipped with, struts piece, described to strut
The both ends of piece horizontal direction are bent to the opposite direction of piece is strutted, and the bottom for strutting piece forms several limiting tooths, described
Limiting tooth outward bending；Described two height for strutting piece are unequal, and the height small strutting forms on the side wall of piece to be led
Blood slot, described lead are equipped with suction tube in blood slot, the end of the suction tube is connected with aspirator；The linking arm is equipped with axle center
Regulating device, the axle center regulating device described strut the distance between piece for adjusting.
Further, the corresponding position for attracting pipe port of blood slot of leading offers grafting set, is equipped in the grafting set
Suction aspirator tip.
Further, it is equipped with interior tube core in the aspirator, said inner tube core is externally provided with triple valve, right on said inner tube core
Answering the position of triple valve to set, there are two opening, described two arc-shaped distributions of opening.
Further, the axle center regulating device includes the molding axle position protrusion in nearly working end and several two on linking arm
End forms the adjustment bar of axis hole.
Further, the distance of the axle position protrusion distance linking arm hinge joint is 1.5-2cm, several adjustment bars
Length 3-15cm.
Further, the length of several adjustment bars is respectively 3cm, 6cm, 9cm, 12cm and 15cm.
Further, the suction aspirator tip is hollow tubular structures, and the working end of the suction aspirator tip is shaped to inclined-plane sword
Structure.
Further, the suction aspirator tip is hollow tubular structures, and the working end of the suction aspirator tip is shaped to hook-shaped knot
Structure.
Further, the suction aspirator tip is hollow tubular structures, and the working end of the suction aspirator tip is shaped to conically shaped
Shape structure.
The beneficial effects of the present invention are: a kind of way of escape canalis spinalis operation minimally invasive retractor of soft tissue proposed by the present invention, benefit
When the way of escape canalis spinalis operation carried out with it for patient, the incision length of skin by traditional cervical posterior approach 5-
10cm is reduced to 2-4cm, and amount of bleeding is reduced to 10-20ml by the 50-100ml of traditional operation, and bleeding is few, and notch is small, greatly
Alleviate sufferer operation when and postoperative pain, and reduce patient spend, small notch can do beauty healing (skin and flesh seam
Close), it is possible to reduce medical resource is saved in hemostatic material application；For medical staff, operating time shortens 30%-
40%, complicated operation is 2-4 hours, and simple operation is 1-2 hour, on the one hand reduces pressure when medical staff performs the operation, one
Aspect is avoided due to the excessively complicated generation for leading to human error of surgical procedure.
