Abstract
The invention provides a technical scheme of a neural traction protector in appliances for medical operation, which comprises a handle, wherein the handle is fixedly connected with a traction rod with a neural stripping claw. The technical scheme of the neural traction protector is characterized in that the traction rod is an axial hollow sleeve body capable of realizing any cross section shapes, a positioning needle capable of moving along the axial line of the traction rod is inserted in an inner cavity of the traction rod, the handle can move along the axial line of the traction rod, and the traction rod and a work sleeve pipe are tightly locked through a connection locking mechanism. Through the structure, the dura mater is stripped from the nervus by the stripping claw during the operation, then, the positioning needle is inserted into the soft tissue for positioning so that the positions of the stripping claw, the dura mater and the nervus are not moved, then, the protector is fixed on the work sleeve pipe through the handle and the connection locking mechanism, the traction fixation on the stripping claw, the dura mater and the nervus does not need to be implemented by artificial force, and the goal that the influence on the operation and the harm to the nervus can not be caused by the artificial traction factors in the operation process is ensured.
Description
Technical field
What the present invention relates to is a kind of used for medical procedures apparatus, especially a kind of neural traction protector of intervertebral disc prolapse operation usefulness.
Background technology
The intervertebral disc prolapse operation all is in working column, to carry out, and when the intervertebral disk hernia focus is undergone surgery, need dura mater and nerve be peeled off protection; In the prior art, all be that armrest art assistant's manpower comes dragline through nerve hook after dura mater and neural the peeling off, when operating time long; The manpower fatigue that dragline is neural, it is improper pulling force to occur, with normally carrying out of influence operation; Even can cause neural damage, this is the existing in prior technology weak point.
Summary of the invention
The object of the invention is exactly not enough to existing in prior technology; And a kind of technical scheme of neural traction protector is provided; This scheme adopts the positioning needle location; With connecting retaining mechanism protector is locked on the working column, has removed from manpower dragline nerve, this has just been avoided disadvantage of leaning on manpower dragline nerve to cause fully.
This programme is realized through following technical measures: neural traction protector; Include handle; This handle is fixedly connected the draw bar that has neural stripping pawl; The characteristics of this programme are that described draw bar is an axial hollow sleeve that any cross-sectional shape can be arranged, and are inserted with the positioning needle that can move along the draw bar axis at the draw bar inner chamber; Described handle can move along the axis of draw bar, and through connecting retaining mechanism locking draw bar and working column.
The concrete characteristics of this programme also have:
Described connection retaining mechanism has an adapter sleeve that connects draw bar and can move along the draw bar axis; On adapter sleeve, be fixedly connected jug, described adapter sleeve through connect rotating shaft with one to be connected latch hinged, be lock cam on the top of described connection latch; Lock cam is hinged through connecting rotating shaft and adapter sleeve; Lock cam can be locked again or loosened the draw bar that passes adapter sleeve, and the bottom that connects latch is a trigger, and connecting latch middle part one side is the briquetting that can contact with working column; Opposite side is through the hinged spring lever of spring lever lower rotary shaft, and the other end of this spring lever is hinged through rotating shaft of spring lever handle and handle.The shape of cross section of described draw bar is circular.
Described connection retaining mechanism has an adapter sleeve that connects draw bar and can move along the draw bar axis; The ramp and the lower inclined plane that become angle with the draw bar axis are arranged on adapter sleeve; This adapter sleeve is through connecting rotating shaft and to be connected latch segment hinged; The briquetting that can contact with working column is arranged at the bottom of said connection latch segment, connect have on the latch segment with handle on the handle bolt match and merge the tapped through hole that the handle bolt can be contacted with the ramp or the lower inclined plane of adapter sleeve.The shape of cross section of described draw bar is oval.
Described connection retaining mechanism has an adapter sleeve that connects draw bar and can move along the draw bar axis; On adapter sleeve, be fixed with the connection latch segment of a semicircle; Locating hole on the top of this connection latch segment has, following locating hole is arranged at the bottom that connects latch segment, and described handle is the handle of hollow; This handle is through connecting rotating shaft and to be connected latch segment hinged; At described handle inner chamber jug locating rod, this handle locating rod can insert last locating hole or the following locating hole that connects on the latch segment according to the position that handle swings up and down, and the handle locating rod also is connected with the locating rod retaining mechanism that is contained in the handle inner chamber; In addition, also be fixed with the fixedly bar-spring sheet of lower ending opening of a upper end in handle outer wall inboard.The shape of cross section of described draw bar is a square.
The beneficial effect of this programme can learn according to the narration to such scheme, because in this scheme, draw bar is that a cross section is oval hollow sleeve, in draw bar, is inserted with the positioning needle that can move along the draw bar axis; Described handle can move along the axis of draw bar, and through connecting retaining mechanism locking draw bar and working column.This structure; When operation, dura mater and nerve are peeled off, positioning needle is inserted in the soft tissue locatees again, make the stripping ZHUANLIAN no longer mobile with neural position with dura mater with the stripping pawl; Then; Through handle be connected retaining mechanism protector be fixed on the working column, this has just realized dura mater and neural peeling off and protecting, and ends the dependence upon manpower and implement stripping pawl and dura mater are fixed with neural tractive; Guaranteed in operation process, can not cause influence and neural infringement because of the factor of manpower tractive to operation.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
