Description

Manual spiral type cutting and suction device for lumbar vertebra

This utility model relates to a kind of medical apparatus, exactly is manual snake gulp type lumbar intervertebral disc spiral type cutting and suction device.

Percutaneous lumbar intervertebral disc excision is that a kind of operative treatment lumbar intervertebral disc that rises in the later stage eighties is deviate from the new technique of disease, this technology is that the vertebral pulp resectoscope is put into pulp cavity by the percutaneous guidance system, melt the vertebral pulp excision and once finish, exempt the hardship of operating on, improve surgical effect with sucking-off; At present this appliances has two kinds of electrodynamic type and manual types; Electrodynamic type apparatus structure complexity, the manufacturing cost height costs an arm and a leg, and the operation requirement is accurate, and program is loaded down with trivial details; The manual type apparatus mostly is the side half-circular cutouts, takes reciprocal ring cutting, and excision extension is little and occur cut-in without ball easily, and the nucleus pulposus that fibrosis is high is felt simply helpless especially; Simultaneously, percutaneous guidance system caliber is thicker, and wound face is big.

The purpose of this utility model is the deficiency that overcomes prior art, provides a kind of tongue cutter formula spiral type cutting and sucking-off once to finish, and effect is safe and reliable, and is simple to operation, cheap manual snake gulp type lumbar intervertebral disc spiral type cutting and suction device.

The purpose of this utility model is achieved in that a kind of manual snake gulp type lumbar intervertebral disc spiral type cutting and suction device, by inner suction pipe, the axis of guide, the inner suction pipe handle, the tongue cutter, outer suction pipe and outer suction pipe handle are formed, it is characterized in that the described inner suction pipe handle (3) and the axis of guide (2) are connected to an integral body, there is suction hole (16) centre, inner suction pipe (1) is connected with the axis of guide (2) and leads to suction hole (16), inner suction pipe (1) stage casing has S v notch v (7), S v notch v (7) front end is tongue cutter (5), mouth shaped gab (9) is arranged on the axis of guide (2), the following groove of mouth shaped gab (9) is embedded with a reed (15), one end of reed (15) is connected at the bottom of the groove, other end perk; Described outer suction pipe handle (14) is provided with a guider screw (10), outer suction pipe handle (14) is connected with outer suction pipe (11), the front end of outer suction pipe (11) is the sealing plug, have spiral type breach (6) near the front end place, the mouth of pipe place, front of spiral type breach (6) embeds the oblique sheet (8) that is connected.

The utility model has the advantages that: 1, this cutting and suction device is taked screw type cutting, thereby cut coverage is big, reaches the multi-faceted suction of cutting, and more cut-in without ball can not occur; 2, can cut suction equally to the higher nucleus pulposus of fibrosis; 3, this cutting and suction device caliber is little, thereby little to patient's wound face; 4, the axis of guide of this cutting and suction device is provided with reed, can only can not reverse by the rotation of Fig. 5 direction of arrow, to prevent error in the operation; 5, this cutting and suction device is simple in structure, and effect is safe and reliable, and is easy and simple to handle, with low cost.

Accompanying drawing 1, this utility model structural representation,

Accompanying drawing 2, outer suction pipe (11) structural representation,

The A of accompanying drawing 3, Fig. 2 is to view,

Accompanying drawing 4, inner suction pipe (1) structural representation,

Accompanying drawing 5, the axis of guide (5) launch sketch map.

Embodiment: attracting mouth (4), leather hose (12) and vacuum extractor (13) is the known existing utensil of general hospital, inner suction pipe handle (3), the axis of guide (2) and inner suction pipe (1) adopt metallic in aggregates, inner suction pipe (1) leads to suction hole (16), one end of inner suction pipe handle (3) is threaded with attracting mouth (4), attracting also has the suction hole in the middle of the mouth (4), attracts mouth (4), leather hose (12) and vacuum extractor (13) to lead to; Referring to Fig. 4, Fig. 5, have mouth shaped gab (9) on the axis of guide (2), the following groove of mouth shaped gab (9) is embedded with a reed (15), in one end of reed (15) is connected at the bottom of the groove, other end perk, thereby the guider screw (10) on the outer suction pipe handle (14) rotation can only be in the direction of arrows in mouth shaped gab (9), can not backward rotation, to prevent operate miss, the leading portion of inner suction pipe (1) has S v notch v (7), and the front end of inner suction pipe (1) is tongue cutter (5), when tongue cutter (5) when operation because of being subjected to the qualification of oblique sheet (8) and spiral type breach (6), tongue cutter (5) needs perk or bending, and S v notch v (7) can play cushioning effect; Outer suction pipe handle (14) also is to adopt metal to make an integral body with outer suction pipe (11), outer suction pipe handle (14) is provided with a guider screw (10), the front end of outer suction pipe (11) is the sealing plug, have spiral type breach (6) after few, spiral type breach (6) front end mouth of pipe place is embedded with an oblique sheet (8), inner suction pipe (1) is inserted from outer suction pipe handle (14) end, as shown in Figure 1, in the mouth shaped gab (9) of guider screw (10) on the axis of guide (2), move into place, at this moment, tongue cutter (5) is subjected to oblique sheet (8) restriction protruding from spiral breach (6), rotates outer suction pipe handle (14) again, and tongue cutter (5) smoothly changes tongue cutter (5) fulcrum along spiral breach (6), tongue cutter (5) is raised, make the outer vertebral pulp of its incision pipe, the vertebral pulp of cutting-out is extracted out by vacuum extractor (13).
