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 use.
Background technology
Intervertebral disc prolapse operation is all to carry out in working column; when intervertebral disk hernia focus is performed the operation; dura mater and nerve need to be peeled off to protection, in the prior art, be all to lean on assistant's manpower to carry out dragline by nerve hook after dura mater and neural peeling off; when operating time long; the manpower of dragline nerve is tired, just there will be pulling force improper, by normally carrying out of impact operation; even can cause neural damage, this is the existing weak point of prior art.
Summary of the invention
Object of the present invention is exactly for the existing deficiency of prior art; and provide a kind of technical scheme of neural traction protector; this scheme adopts positioning needle location; with connecting retaining mechanism, protector is locked on working column; removed from manpower dragline nerve, this has just been avoided the disadvantage causing by manpower dragline nerve completely.
This programme is realized by three kinds of art measures of following skill:
The neural traction protector of the first embodiment, include handle, this handle is fixedly connected with the draw bar with nerve stripping pawl, is characterized in that described draw bar is an axial hollow sleeve that can have random cross-sectional shape, is inserted with the positioning needle moving along draw bar axis at draw bar inner chamber, described handle can move along the axis of draw bar, and by connecting retaining mechanism locking draw bar and working column, the adapter sleeve that described connection retaining mechanism has a draw bar connection and can move along draw bar axis, on adapter sleeve, be fixedly connected with jug, described adapter sleeve by connection rotating shaft with one to be connected latch hinged, top at described connection latch is lock cam, lock cam is hinged by connection rotating shaft and adapter sleeve, the draw bar through adapter sleeve can be locked or loosen to lock cam again, the bottom that connects latch is trigger, connecting latch middle part one side is the briquetting contacting with working column, opposite side is by one end of the hinged spring lever of spring lever lower rotary shaft, the other end of this spring lever is hinged by the rotating shaft of spring lever handle and handle.The concrete feature of this programme is that the shape of cross section of described draw bar is circular.
The neural traction protector of the second embodiment, include handle, this handle is fixedly connected with the draw bar with nerve stripping pawl, is characterized in that described draw bar is an axial hollow sleeve that can have random cross-sectional shape, is inserted with the positioning needle moving along draw bar axis at draw bar inner chamber; Described handle can move along the axis of draw bar, and by connecting retaining mechanism locking draw bar and working column; The adapter sleeve that described connection retaining mechanism has a draw bar connection and can move along draw bar axis, on adapter sleeve, there are the ramp and the lower inclined plane that become angle with draw bar axis, this adapter sleeve by connection rotating shaft with to be connected latch segment hinged, the briquetting contacting with working column is arranged at the bottom of described connection latch segment, matches and merges the tapped through hole that handle bolt can be contacted with ramp or the lower inclined plane of adapter sleeve connecting to have on latch segment with handle bolt on handle.The concrete feature of this programme is that the shape of cross section of described draw bar is oval.
The neural traction protector of the third embodiment, include handle, this handle is fixedly connected with the draw bar with nerve stripping pawl, is characterized in that described draw bar is an axial hollow sleeve that has random cross-sectional shape, is inserted with the positioning needle moving along draw bar axis at draw bar inner chamber, described handle can move along the axis of draw bar, and by connecting retaining mechanism locking draw bar and working column, the adapter sleeve that described connection retaining mechanism has a draw bar connection and can move along 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, lower locating hole is arranged at the bottom that connects latch segment, described handle is the handle of hollow, this handle by connection rotating shaft with to be connected latch segment hinged, at described handle inner chamber jug locating rod, upper locating hole or the lower locating hole connecting on latch segment inserted in the position that this handle locating rod swings up and down according to handle, handle locating rod is also connected with the locating rod retaining mechanism that is contained in handle inner chamber, in addition, in handle outer wall inner side, be also fixed with the fixedly bar-spring sheet of lower ending opening of a upper end.The concrete feature of this programme is that the shape of cross section of described draw bar is square.
The beneficial effect of this programme can be according to the narration of above-mentioned three schemes is learnt, due in these three schemes, draw bar is that a cross section is oval hollow sleeve, is inserted with the positioning needle that can move along draw bar axis in draw bar; Described handle can move along the axis of draw bar, and by connection retaining mechanism locking draw bar and the working column of three kinds of different structures.This structure; when operation, with stripping pawl, dura mater and nerve are peeled off; again positioning needle is inserted in soft tissue and is located; making to shell ZHUANLIAN no longer moves with dura mater and neural position; then; by handle be connected retaining mechanism protector be fixed on working column; this has just realized dura mater and neural peeling off and protect; and do not rely on manpower and implement stripping pawl and dura mater and neural tractive to fix; guaranteed in operation process, can not cause because of the factor of manpower tractive the impact of operation and neural infringement.As can be seen here, the present invention compared with prior art, has outstanding substantive distinguishing features and significant progressive, and the beneficial effect of its enforcement is also apparent.
