Abstract
The utility model discloses a guide sleeve marrow sampler, belonging to medical appliances. The guide sleeve marrow sampler comprises a side poet sleeve of which one end is a spherical crown and a side face is provided with an opening, a controllable guide sleeve is arranged in the side port sleeve, diameter of the controllable guide sleeve is not more than radius of the spherical crown, one end of the controllable guide sleeve is provided with a plurality of connected sawteeth, and neighboring sawteeth are hinged together. While using the guide sleeve marrow sampler, the controllable guide sleeve is placed in the side port sleeve, and then a biopsy forceps is placed in the controllable guide sleeve, the biopsy forceps and the controllable guide sleeve are moved together to the right, when the biopsy forceps and the controllable guide sleeve are blocked by the spherical crown on the side port sleeve, the mutually hinged sawteeth are bent to drive the biopsy forceps to be bent together, so that a head end of the biopsy forceps directly reaches a protruding intervertebral disk nucleus pulposus, and part of protruding nucleus pulposus is taken out or pulled back according to an opening and closing order of the biopsy forceps, thereby implementing treatment on herniated disk symptom without performing an operation.
Description
Technical field
This utility model belongs to medical apparatus and instruments, is specifically related to a kind of device for the treatment of intervertebral disk hernia.
Background technology
At present, the radical treatment of neck, prolapse of lumbar intervertebral disc mainly contains surgical operation and two kinds of methods of percutaneous aspiration cutting.Yet the surgical risk height, painful big, recover slow, how not accepted by the patient; Though and the percutaneous aspiration cutting has advantages such as risk is low, misery is little, recovery is fast, accepted by the patient easily, but its operating process be from the other approach of spinal column to intervertebral disc, and the suction sickle that uses and get the marrow pincers be directly to, acutangulate with corresponding vertebral body vertebral pulp center sagittal line, operating process can not reduce part patient curative effect or the treatment failure with outstanding vertebral pulp toward pulling back or taking out.
The utility model content
Get marrow pincers when the technical problems to be solved in the utility model is percutaneous aspiration cutting treatment intervertebral disk hernia and can not turn to and cause operative effect to reduce, provide a kind of guide thimble that can turn to get the marrow device.
The technical solution of the utility model realizes in the following manner: a kind of guide thimble is got the marrow device, comprise the side opening sleeve pipe, side opening sleeve pipe one end is a spherical crown, and side opening sleeve pipe side is provided with opening, be provided with controlled guide thimble in the side opening sleeve pipe, the diameter of controlled guide thimble is not more than the radius of spherical crown, and an end of controlled guide thimble is provided with a plurality of continuous sawtooth, and adjacent sawtooth is hinged and connected.
Angle α between the described adjacent sawtooth is 45 ° ~ 60 °.
In this utility model, controlled guide thimble right-hand member has a plurality of sawtooth to link to each other, and is hinged between the sawtooth; The right flank of controlled guide thimble is provided with opening, during use controlled guide thimble is put into the side opening sleeve pipe, again biopsy forceps is put into controlled guide thimble, afterwards biopsy forceps and controlled guide thimble are moved right together, when running into spherical crown on the side opening sleeve pipe and stopping, bending can take place in the sawtooth that is hinged, drive biopsy forceps bending together, make the through outstanding nucleus pulposus of biopsy forceps head end, the part vertebral pulp that utilizes the folding of biopsy forceps to take out smoothly or pull back out outstanding again, and then reach and do not operate on treatment intervertebral disk hernia symptom.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is this utility model user mode sketch map.
Fig. 3 is the structural representation of controlled guide thimble in this utility model.
The specific embodiment
Shown in Fig. 1 ~ 3, this utility model comprises side opening sleeve pipe 1, side opening sleeve pipe 1 one ends are spherical crown 3, and side opening sleeve pipe 1 side is provided with opening 2, be provided with controlled guide thimble 5 in the side opening sleeve pipe 1, the diameter of controlled guide thimble 5 is not more than the radius of spherical crown 3, and an end of controlled guide thimble 5 is provided with a plurality of continuous sawtooth 6, and adjacent sawtooth 6 is hinged and connected.
Angle α between the described adjacent sawtooth 6 is 45 ° ~ 60 °, such as 45 °, 50 °, 55 °, 60 ° etc.Connecing the foursquare length of side in place, the end circle of described spherical crown 3 should could make sawtooth 6 smooth bendings turn to greater than the distance L between the adjacent sawtooth 6.
This utility model use is as follows: at first controlled guide thimble 5 is put into side opening sleeve pipe 1, then biopsy forceps is put into controlled guide thimble 5, promoting controlled guide thimble 5 moves right, under the resistance of spherical crown 3, bending takes place for one section in sawtooth, after reaching required angle of bend, corresponding also bending thereupon of biopsy forceps, the folding by the biopsy forceps jaw realizes the gripping to vertebral pulp.
Claims (2)
