Abstract
The utility model discloses a minimally-invasive vertebral pedicle osteotome which belongs to a medical operative instrument and is used for vertebral pedicle osteotomy in operations such as whole vertebral body excision and artificial vertebral body replacement. The osteotome is in a structure of an inner-blade osteotome with a handheld stem, the blades of the osteotome are inner blades without sharp corners, the inner blades achieve an anatomic fit with a vertebral pedicle, a certain angle is formed between the blades and a blade base so as to be convenient to insert for osteotomy, and the handheld stem comprises a knocking platform so as to bring convenience for doctors to perform vertebral pedicle osteotomy. The minimally-invasive vertebral pedicle osteotome is simple and reliable in structure, convenient to operate, safe, and low in cost.
Description
Technical field:
The present invention relates to a kind of novel Wicresoft's pedicle of vertebral arch osteotome, belong to medical operation device.Can carry out for needs the operation such as full vertebral resection art, artificial vertebral body replacement of pedicle of vertebral arch osteotomy.
Background technology:
The multinomial new capital operation of spinal surgery all needs pedicle of vertebral arch is carried out to osteotomy, comprises the modus operandis such as full vertebral resection art through the way of escape, artificial vertebral body replacement.These operations are promoted over several years gradually clinical expansion, and how reaching convenient and safe pedicle of vertebral arch osteotome is the key point of operation.
More scholar advocates to adopt the mode of scroll saw pedicle of vertebral arch osteotomy at present, and nerve root is retracted, and after the spinal nerves protection, through the traction of soft sleeve, around pedicle of vertebral arch, pulls out flexible pipe, and by scroll saw, by passing in sleeve, lasting coming and going pulls scroll saw, completes the pedicle of vertebral arch osteotomy.
But the shortcoming that this mode is brought is: 1. comparatively loaded down with trivial details spinal nerves and nerve root protection, for the scroll saw incision, face the problem of rear spinal nerves and nerve root protection in the time of the pedicle of vertebral arch osteotomy, be no matter by nerve retract, the methods such as distributing line sawing, neuroprotective device all can cause performing the operation complicated, also promoted operation risk when increasing operation technique, extended operating time; 2. the pedicle of vertebral arch osteotomy is uncontrollable, and the scroll saw feel is poor, when with scroll saw, cutting pedicle of vertebral arch, often needs the scroll saw of tractive repeatedly of doctor's long period, can reach the pedicle of vertebral arch osteotomy.
Visible, to develop a kind of simple and reliable for structurely, operation technique is convenient, and the pedicle of vertebral arch osteotomy device little to the human body wound has important realistic meaning to carrying out of operation such as full vertebral resection art, artificial vertebral body replacements.
Summary of the invention:
In order to overcome the problems referred to above of existing scroll saw incision, the purpose of this invention is to provide a kind of simple and reliable for structurely, operation technique is convenient, little to the human body wound, pedicle of vertebral arch osteotomy instrument-" Wicresoft's pedicle of vertebral arch osteotome ", use the incision of intervertebral disc in Rhizoma Atractylodis Macrocephalae cheaply.
For achieving the above object, technical scheme of the present invention is:
(1) on structure: the present invention is the inner edge osteotome structure adopted with hand holding handle, be characterized in: osteotome is divided into cutter head section, extend shank, hand-held shank, cutter head section comprises the blade part of oblique angle band inner edge, the blade pedestal, blade part can carry out the pedicle of vertebral arch osteotomy, blade part is compared with the blade pedestal with certain oblique angle, oblique insertion anatomic space is operated respectively, like this space size is required greatly to reduce, can avoid traditional osteotome blade must integral body to enter the shortcoming that anatomic space can osteotomy, oblique angle can guarantee that blade part is when thoracic vertebra way of escape osteotomy simultaneously, by the vertebral plate gap covered through upper and lower imbricate, enter, reach pedicle of vertebral arch and carry out osteotomy, reduced the wound of operation, facilitated operation technique, and for the requirement of neuroprotective lower than scroll saw osteotomy method.
(2) point of a knife of blade part has been for to have avoided the damage to surrounding structure without the arc of wedge angle, and the outline of the form of inner edge and pedicle of vertebral arch coupling can be carried out the osteotomy operation easily.
(3) the hand holding handle end, for knocking platform, is conveniently knocked.
The invention has the beneficial effects as follows a kind of novel Wicresoft's pedicle of vertebral arch osteotome of design, it takies less anatomic space, the vertebral plate gap that can cover through upper and lower imbricate enters, reduce the risk of spinal nerves and nerve root injury, it is simple to operate simultaneously, is applicable to the operations such as full vertebral resection art, artificial vertebral body replacement.
The accompanying drawing explanation:
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is graphics of the present invention.
Fig. 2 is side view of the present invention.
Fig. 3 is top view of the present invention.
Fig. 4 is top view after blade part of the present invention amplifies.
The schematic diagram that Fig. 5 is pedicle of vertebral arch osteotomy of the present invention.
The specific embodiment:
In Fig. 1-5, the 1st, blade part, the 2nd, prolonging handle, the 3rd, hand holding handle, each one of 1-3 is the ingredient of pedicle of vertebral arch osteotome.
4, the 5th, two nose part without wedge angle of blade part, 6 are and the inner edge of pedicle of vertebral arch anatomical compatibility, and 7 is the blade pedestal, and 8 for knocking platform, and 9 for treating the pedicle of vertebral arch of osteotomy.
Can the doctor during operation pedicle of vertebral arch osteotome 1 can be placed into and need the pedicle of vertebral arch of osteotomy position, then blade part is stuck on pedicle of vertebral arch to clamping stable, to the afterbody through hand holding handle, knock osteotomy; The vertebral plate gap that perhaps blade part can be covered by upper and lower imbricate enters, and is stuck on pedicle of vertebral arch and carries out osteotomy.
Claims (4)
1. a novel pedicle of vertebral arch osteotome, for realizing the pedicle of vertebral arch osteotomy of Wicresoft, it is designed to adopt by cutter head section, extends the osteotome of the inner edge with the hand holding handle structure that shank, hand-held shank form.
2. pedicle of vertebral arch osteotome according to claim 1, it is characterized in that: the cutter head section of pedicle of vertebral arch osteotome comprises blade part, the blade pedestal of oblique angle band inner edge, blade part is inner edge, the point of a knife of blade part is the arc without wedge angle, and blade part is compared with certain oblique angle with the blade pedestal.
3. pedicle of vertebral arch osteotome according to claim 1, is characterized in that: the inner edge of pedicle of vertebral arch osteotome and pedicle of vertebral arch anatomic form coupling.
4. pedicle of vertebral arch osteotome according to claim 1, it is characterized in that: the hand holding handle end of pedicle of vertebral arch osteotome is for knocking platform.
