Abstract

The utility model discloses a washing aspirator for cervical disc belonging to the medical equipment, in particular to a nucleus cavity washing aspirator for percutaneous cervical disc nucleus cavity extraction, which comprises a pipette 1. A pipette backseat is arranged on the outside of the upper end of the pipette 1, and is connected with a handle 3 in turn. The utility model is characterized in that a flush pipe 4 is intermittently sleeved with the lower end of the handle 3 and the external walls of the aspiration pipe 1, and a cavity hole formed on the upper end of the flush pipe 4 is extended out of walls from the inner of the handle 3 to communicate with a transfusion interface 2, and at least two injection lateral-holes 5 are arranged on the circumference walls of the lower end of the flush pipe 4. The utility model is a washing aspiration device which is particularly applicable to cervical disc herniation interventional therapy, and also is applicable to a nucleus cavity washing aspiration device for lumbar disc anterior approach and side back approach interventional therapies.

Description

The cervical intervertebral disk flushing aspirator

Technical field

The cervical intervertebral disk flushing aspirator that this utility model relates to belongs to medical apparatus and instruments, is the nucleus pulpous cavity flushing aspirator tool of skin puncture resection of nucleus pulposus of cervical disc specifically.

Background technology

Prolapse of cervical intervertebral disc is a kind of commonly encountered diseases, and the interventional therapy primary disease is a kind of minimally-invasive treatment, and its effect has more advantage than open surgery.The cutting and suction device that adopts in the interventional procedure in the past, the liquid that enters by cutting and suction device only arrives the cutting and suction device distal chamber and promptly is attracted device and sucks back, play the nucleus pulpous cavity flushing action at all, and it is occupied to attract the big portion of tube chamber to be cut cutter, so little residual nucleus pulposus sucking-off is external, and vacuum suction undercapacity, seriously influence the interventional therapy effect, existing recovery tube far-end has only a side opening, and the termination keeps a dead space, at easy extruding nucleus pulpous cavity rear wall of when operation, be unfavorable for that the disc tissue of giving prominence to also receives.

Summary of the invention

The purpose of this utility model is intended to improve many deficiencies of above-mentioned cutting and suction device, broken and cut suction mode in the past, provide a kind of liquid that makes to pass through directly to inject nucleus pulpous cavity towards the side opening of liquid tube chamber far-end, external from opening the central suction pipe sucking-off of expansion then, nucleus pulposus residual in the nucleus pulpous cavity is removed, also strengthened simultaneously the negative pressure intensity of nucleus pulpous cavity, the cervical intervertebral disk flushing aspirator that the disc tissue that helps giving prominence to is also received.

In order to achieve the above object, this utility model is to realize like this, it has a suction pipe 1, suction pipe 1 upper end has the suction pipe back seat outward, the suction pipe back seat connects one handle 3 successively, be characterized in, in handle 3 lower ends, at suction pipe 1 outer wall intermittent sleeve one towards liquid pipe 4, the lumen pore that forms towards liquid pipe 4 upper ends extends in handle 3 wall outside and is connected with the interface 2 of infusing, and establishes the fluid injection side opening 5 more than 2 on the liquid pipe 4 lower end circumferential wall at least.

Wherein fluid injection side opening 5 is 2-4.

This utility model is simple in structure, novel, reached when making intervene operation, make liquid pass through directly to inject nucleus pulpous cavity towards the side opening of liquid pipe far-end, external from the central suction pipe sucking-off of opening expansion then, nucleus pulposus residual in the nucleus pulpous cavity is removed, also strengthened simultaneously the negative pressure intensity of nucleus pulpous cavity, the disc tissue that helps giving prominence to is also received, and obviously improves therapeutic effect, and this utility model is present a kind of more satisfactory cervical intervertebral disk flushing aspirator.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

Suction pipe 1, suction pipe back seat, handle 3, transfusion interface 2, all adopt stainless steel material to make towards liquid pipe 4.Suction pipe 1 can adopt external diameter Φ 1.5mm, inner chamber Φ 1mm, the stainless steel tube of long 177mm is made, weld a suction pipe back seat successively in suction pipe 1 upper end, one handle 3, establish two annulus on the suction pipe back seat outer wall, in order to joining with the vacuum extractor sebific duct, go up the prismatic that intersects with the cutter cutting on handle 3 outer circle walls, in case operation the time is sent out cunning, the suction pipe back seat can make Φ 6mm, and handle 3 can make Φ 14mm, long 40mm, bore a hole on handle 3 lower end sidewalls, and weld a transfusion interface 2, transfusion interface outer wall can make the convex-concave ring-type, be beneficial to be connected with the transfusion device pipe sealing, in handle 3 lower ends, towards liquid pipe 4, the lumen pore that forms towards liquid pipe 4 upper ends is connected with the interface 2 of infusing at suction pipe 1 outer wall intermittent sleeve one, establishes the fluid injection side opening 5 more than 2 on the liquid pipe 4 lower end circumferential wall at least, fluid injection side opening 5 can be established 2-4, for formality needs, the diameter of fluid injection side opening, changeable.Can be Φ 3mm towards the liquid pipe, long 118mm is welded in handle 3 lower ends and gets final product.

When concrete operations are used, the suction pipe of vacuum extractor is connected on the suction pipe back seat of suction pipe 1 upper end, be tightly connected, the transfusion interface is connected with disposable transfusion device is supporting, when subcutaneous incision need be done the intervertebral disc operation position, operate with operating forceps, by transfusion interface 2 flushing liquid is transported to the fluid injection side opening, spray into nucleus pulpous cavity by the fluid injection side opening, because suction pipe far-end suction inlet communicates with vacuum extractor, the residual nucleus pulposus of the liquid of intracavity and postoperative directly is collected in central suction pipe and excretes, also can be by the transfusion interface with the through nucleus pulpous cavity of medicinal liquid.

This utility model is specially adapted to a kind of flushing aspirator tool of prolapse of cervical intervertebral disc interventional therapy.

This utility model also is suitable for the nucleus pulpous cavity flushing aspirator tool of lumbar intervertebral disc anterior approach and two kinds of interventional therapy operations of rear flank approach.

Claims

1, a kind of cervical intervertebral disk flushing aspirator, it has a suction pipe (1), suction pipe (1) upper end has the suction pipe back seat outward, the suction pipe back seat connects one handle (3) successively, it is characterized in that, towards liquid pipe (4), the lumen pore that forms towards liquid pipe (4) upper end extends in handle (3) wall outside and is connected with the interface (2) of infusing in handle (3) lower end, at suction pipe (1) outer wall intermittent sleeve one, establishes the fluid injection side opening (5) more than 2 on liquid pipe (4) the lower end circumferential wall at least.
