Description
Technical field
The utility model belongs to technical field of medical instrument more particularly to a kind of novel lumbar surgical denervation drag hook.
Background technique
Currently, the prior art commonly used in the trade is such that
In conventional spinal surgical operation, in order to expose the tissue such as intervertebral disc of lumbar vertebra, it is necessary to retract lumbar vertebrae nerve root.But by
Smaller in the lumbar surgery visual field, lumber ertebral disc appears and cuts off more difficulty.It is led in clinical operation usually using nerve hook
Dural sac and nerve root are opened to realize the purpose of interverbebral disc exposure, traditional nerve hook is at its edge and nerve root and dural sac
Contact position is easy to cause nerve root and dural sac card to press and damage, can not complete patron saint in Invasive lumbar fusion device implantation process
Through, in fact it could happen that nerve root or dural sac are involved in intervertenral space, cause the serious consequence of dural sac and nerve root injury.Traditional mind
Edge through drag hook is easy to form card pressure and damage to nerve root and dural sac in the course of surgery.Meanwhile traditional nerve is drawn
Hook can not protect nerve root and dural sac completely, nerve root or dural sac may be involved in vertebra in Invasive lumbar fusion device implantation process
Gap leads to its damage.
In conclusion problem of the existing technology is:
(1) edge of traditional nerve hook is easy to form card pressure and damage to nerve root and dural sac in the course of surgery
Wound.
(2) traditional nerve hook can not protect nerve root and dural sac completely, can in Invasive lumbar fusion device implantation process
Nerve root or dural sac can be involved in intervertenral space, lead to its damage.
Solve the difficulty and meaning of above-mentioned technical problem:
(1) above problem can by change nerve hook end and nerve root and dural sac contact position form come
It solves, why which does not solve for a long time, mainly due to not drawing for damaging in nerve root and dural sac art
It plays enough attention and lacks the profound understanding for improving surgical instrument brought potential advantage.
(2) above problem can reduce the stretch injury and reality of nerve root and dural sac in art to greatest extent after solving
The safety of existing Invasive lumbar fusion device is smoothly implanted into, and is shortened operating time, is reduced bleeding.
Utility model content
In view of the problems of the existing technology, the utility model provides a kind of novel lumbar surgical denervation drag hook.
The utility model is realized in this way a kind of novel lumbar surgical denervation drag hook is provided with
Connecting rod；
Connecting rod is arc, and connecting rod left end is provided with the pulling plate of integrated molding, is provided with integration on the right side of connecting rod
Molding drag hook.
Further, two sides are provided with curved baffle on the upside of drag hook.
In conclusion the advantages of the utility model and good effect are as follows:
The connecting rod of the utility model is arc, card of nerve can be pressed and be damaged to avoid it, can by curved baffle
To protect nerve completely, avoid harm to the human body.
Detailed description of the invention
Fig. 1 is novel lumbar surgical denervation hook structure schematic diagram provided by the embodiment of the utility model.
In figure: 1, connecting rod；2, pulling plate；3, curved baffle；4, drag hook.
Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing.
As shown in Figure 1, novel lumbar surgical denervation drag hook provided by the embodiment of the utility model includes: connecting rod 1, pulling plate
2, curved baffle 3, drag hook 4.
Connecting rod 1 is arc, and 1 left end of connecting rod is provided with the pulling plate 2 of integrated molding, is provided with one on the right side of connecting rod 1
The molding drag hook 4 of bodyization, 4 upside two sides of drag hook are provided with curved baffle 3.
The working principle of the utility model are as follows:
In use, driving 4 pairs of nerves of drag hook to operate by pulling dynamic pulling plate 2, can be protected completely by curved baffle 3
Shield nerve, connecting rod 1 are arc, can be to avoid it to the card pressure of nerve and damage.
The above is only the preferred embodiment to the utility model, is not made in any form to the utility model
Limitation, it is all according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with
Modification, is all within the scope of the technical scheme of the utility model.
