Abstract
The invention provides a suction head of a suction apparatus with a cutting function for an endoscope. The suction head comprises a circular tube body and a suction port at the front end, wherein an annular cutter is arranged in the circular tube body; the front end of the cutter is provided with a cutting-edge-shaped or tooth-shaped structure, and the back end of the cutter is connected to the inner wall of the circular tube body; and the front end of the cutter faces the suction port, and is 2-5 millimeters away from the suction port. According to the suction head provided by the invention, soft tissues which prevent tissue forceps from passing through can be cut through the cutter in the suction apparatus, and the tissue forceps can break through successfully and easily, so that operation becomes easy; and meanwhile, the structure and size of each position are combined organically in the suction head under the consideration of the problems of efficiency and safety in a surgery process, so that good cutting and suction effects are ensured simultaneously, and the surgery safety is ensured.
Description
Technical field
The present invention relates to the sucking head with cutting function suction pump for the mirror of a kind of chamber.
Background technology
Suction pump, is the content for absorbing hands intraoperative hemorrhage, exudate, pus, thoracic organ, makes to perform the operation clear, reduces opportunities for contamination.Removing hematocele in operation or hydrops, the broken ends of fractured bone of controlling the blood vessel that breaks etc., all be unable to do without suction pump.
Suction pump is also everlasting and is coordinated that tissue is free and blood vessel is free in endoscope-assistant surgery, is mainly the oozing of blood siphoning away in anatomic tissue process.Free dissociating with blood vessel of tissue is mainly to adopt tissue forceps blunt separation, tissue forceps usually runs into keeping out of soft tissue in the time walking around certain important structure as blood vessel and bronchus, due to the limitation of endoscope-assistant surgery, can only use larger strength to force one's way through the barrier, normal hyperamization pipe or bronchus damage.Can coordinate tissue forceps to break through easily soft tissue if there is a kind of apparatus, will make operation process become to be more prone to, safety.
Summary of the invention
The object of the present invention is to provide a kind of in a organized way cutting function have again the chamber mirror suction device of suction function.
The invention provides the sucking head with cutting function suction pump for the mirror of a kind of chamber, comprise the suction port of circular body and front end; In circular body, have annular sickle, sickle front end has bladed or dentalation, and rear end is connected on circular inboard wall of tube body; Sickle front end is towards suction port, apart from suction port 2-5mm.
Wherein, described sickle front end is apart from suction port 3mm.
Wherein, between described sickle sidewall and circular body tube wall, be 5-30 ° of angle.
Further, described sickle front end is bladed structure, between sidewall and circular body tube wall, is 5-15 ° of angle.
Wherein, the distance of sickle front end and circular inboard wall of tube body is 0.5-1.5mm.
Further, the distance of sickle front end and circular inboard wall of tube body is 1mm.
Wherein, on described circular body, be also provided with at least two side openings.
Further, described side opening lays respectively at the front and back of sickle.
Sucking head of the present invention, can be cut and be stopped the soft tissue that tissue forceps passes through by the sickle in suction pump, and tissue forceps can easily be broken through smoothly, thereby makes operation become easy; Meanwhile, consider efficiency and the safety issue of operation process, sucking head of the present invention, by the organic assembling to each portion structure, size, has ensured good cutting simultaneously and has attracted effect, for operation safety provides guarantee.
Brief description of the drawings
Fig. 1 structural representation of the present invention;
Wherein, the circular body of 1-, 2-suction port, 3-sickle.
Detailed description of the invention
Known in conjunction with Fig. 1, the present invention is a kind of sucking head that has cutting function to have again the chamber mirror suction pump of suction function, comprises the suction port 2 of circular body 1 and front end; In circular body 1, have annular sickle 3, sickle 3 front ends have bladed or dentalation, and rear end is connected on circular body 1 inwall; Sickle 3 front ends are towards suction port 2, apart from suction port 22-5mm.
The distance of described sickle 3 front ends and suction port 2 is preferably 3mm.
Wherein, between described sickle 3 sidewalls and circular body 1 tube wall, be 5-30 ° of angle.
Described sickle 3 front ends are 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, on described circular body 1, be also provided with at least two side openings.
Described side opening lays respectively at the front and back of sickle 3.
In endoscope-assistant surgery, when by important structure such as the free blood vessel of tissue forceps, bronchus, can adopt this cutting aspirator to siphon away oozing of blood, and tissue forceps is docked with this cutting aspirator head and suitably insert, cut and stop the soft tissue that tissue forceps passes through by the sickle in 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, sickle is arranged on sucking head inside by the present invention, avoids directly damaging in-vivo tissue, blood vessel etc.; But, sickle is placed in to suction pump inside, also there are some technology barriers, the present invention is set as follows sucking head for this reason:
(1) in to research of the present invention, find, when sickle and suction port spacing are when long, cutting is less than the tissue being headed into; If distance is too short, can accidentally injure the soft tissue of accidental suction, patient is caused to unnecessary damage.Therefore, the distance of sickle front end and suction port is made as to 2-5mm, and preferred 3mm.
(2) in order to strengthen the present invention's cutting effect to soft tissue, sickle is arranged to a fixed angle of altitude, so that the soft tissue reaching being headed into is realized squash type cutting; But if the elevation angle of sickle is excessive, its cutting effect will decline to a great extent; , find under study for action meanwhile, when the distance of sickle front end and circular body is too small, cannot effectively realize the cutting of soft tissue; In the time that distance is excessive, due to the existence at the sickle elevation angle, sickle can hinder the suction function of suction pump, cannot effectively absorb the content in hands intraoperative hemorrhage, exudate, pus, thoracic organ, will have a strong impact on operation safety.Therefore, cutting effect and attraction effect are considered, in the present invention, set, the distance of sickle front end and circular inboard wall of tube body is 0.5-1.5mm, preferably 1mm; Between sickle and circular body, be 5-30 ° of angle, preferably 5-10 °.
(3) in order to ensure the suction function of sucking head, also on circular body, side opening is set, to absorb oozing of blood etc. from both sides; In the present invention, because sickle is present in sucking head inside, and have a fixed angle of altitude, this also may be to attracting effect cause certain influence, and therefore, in order further to ensure suction function, the present invention all arranges side opening in the front and back of sickle.
(4) in order to ensure cutting effect, in the present invention, sickle opening is preferably bladed structure.
In sum, sucking head of the present invention, can be cut and be stopped the soft tissue that tissue forceps passes through by the sickle in suction pump, and tissue forceps can easily be broken through smoothly, thereby makes operation become easy; Meanwhile, consider efficiency and the safety issue of operation process, sucking head of the present invention, by the organic assembling to each portion structure, size, has ensured good cutting simultaneously and has attracted effect, for operation safety provides guarantee.
