Description of drawings
Fig. 1 structural representation of the present invention;
Wherein, the circular body of 1-, 2-attract mouth, 3-sickle.
The specific embodiment
Can know that in conjunction with Fig. 1 the present invention promptly has cutting function that the attraction head of the chamber mirror of attraction function with suction pump arranged again for a kind of, comprises the attraction mouth 2 of circular body 1 and front end; In the circular body 1 annular sickle 3 is arranged, sickle 3 front ends have bladed or dentalation, and the rear end is connected on circular body 1 inwall; Sickle 3 front ends are towards attracting mouth 2, and distance attracts a mouthful 22-5mm.
Said sickle 3 front ends are preferably 3mm with the distance that attracts mouth 2.
Wherein, be 5-30 ° of angle between said sickle 3 sidewalls and circular body 1 tube wall.
Said sickle 3 front ends are the bladed structure, preferred 5-15 ° of angle between sidewall and circular body 1 tube wall.
Wherein, the distance of sickle 3 front ends and circular body 1 inwall is 0.5-1.5mm.
The distance of sickle 3 front ends and circular body 1 inwall is preferably 1mm.
Wherein, also be provided with at least two side openings on the said circular body 1.
Said side opening lays respectively at the front and back of sickle 3.
In endoscope-assistant surgery; When with important structure such as the free blood vessel of tissue forceps, bronchus; Can adopt this cutting suction pump to siphon away oozing of blood, and tissue forceps is docked with this cutting suction pump head and suitably inserts, stop the soft tissue that tissue forceps passes through through the incision of the sickle in the suction pump; Tissue forceps can easily be broken through smoothly, thereby operation is become easily and safety.
In order to ensure the safety of operation, the present invention is arranged on sickle and attracts head inner, avoids directly damaging in-vivo tissue, blood vessel etc.; Yet, place suction pump inner sickle, also there are some technology barriers, the present invention does following the setting to attracting head for this reason:
Find in to research of the present invention that (1) when distance was long between sickle and attraction mouth, cutting was less than the tissue that is headed into; If distance is too short, then can accidentally injure the accidental soft tissue that sucks, the patient is caused unnecessary damage.Therefore, sickle front end and the distance that attracts mouth are made as 2-5mm, and preferred 3mm.
