Abstract
The invention provides a suction nozzle used for the minimally invasive surgery. The suction nozzle comprises a circular-truncated-cone-shaped suction head and a cylinder-shaped connector which are in an integrated structure and made of zirconia ceramic material, wherein a central through hole is formed in the axial center of the circular-truncated-cone-shaped suction head and the cylinder-shaped connector, and 2-5 axial lead small holes are formed in the periphery of the central through hole; the inclined angle of the front end part of the circular-truncated-cone-shaped suction head is 15-22 degrees; a U-shaped shallow sinking groove surrounding the central through hole is formed in the front end surface of the circular-truncated-cone-shaped suction head; four axial lead small holes are uniformly distributed in the periphery of the central through hole, and are positioned within the half area of the front end surface of the circular-truncated-cone-shaped suction head, the U-shaped shallow sinking groove is also positioned within the half area, and at least two of the axial lead small holes are contained in the U-shaped shallow sinking groove; the inclined angle of the front end part of the circular-truncated-cone-shaped suction head is 18.1 degrees. The suction nozzle used for the minimally invasive surgery has the advantages that the structure is simple, the use is convenient and reliable, the safety is good, an electricity discharge lead can be conveniently fixed, so that the safe use of the lead is guaranteed, the flow velocity and flow rate of a sucked-in object can be effectively controlled, etc.
Description
Technical field
The present invention relates to a kind of suction nozzle for Minimally Invasive Surgery, belong to the special-purpose member technical field of armarium.
Background technology
Minimally Invasive Surgery, as the term suggests being exactly the operation of microtrauma, is primarily referred to as the operation utilizing the modern medical equipment such as peritoneoscope, thoracoscope and relevant device to carry out；It more focuses on the psychology of patient, society, physiology (pain), mental outlook, the improvement of quality of life and rehabilitation, at utmost shows a patient every consideration, alleviates the misery of patient.For the apparatus of Minimally Invasive Surgery in addition to the modern medical equipment such as peritoneoscope, thoracoscope and equipment, Special sucker must also be included, for aura is treated, the use safety that this Special sucker does not require nothing more than can be fixed electrical discharge wire, ensure wire, but also allowing for flow velocity and the flow etc. controlling to suck object, the Special sucker used at present is high owing to there is the cost of material made, thus cost is high, make difficulty, structurally there is also the drawbacks such as not reasonable.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, and a kind of simple in construction is provided, easy to use and reliable, safety is good, electrical discharge wire can be fixed easily, it is ensured that the safe handling of wire, and flow velocity and the suction nozzle for Minimally Invasive Surgery of flow sucking object can be efficiently controlled.
It is an object of the invention to complete by following technical solution, a kind of suction nozzle for Minimally Invasive Surgery, it includes the Rotary-table suction nozzle that is made into integration by zirconia ceramics material and cylindric connector, the axle of described Rotary-table suction nozzle and cylindric connector is provided centrally with a central through hole, and the periphery at described central through hole is provided with 2-5 axial lead aperture；Described Rotary-table suction nozzle leading section angle is 15 22；Described Rotary-table suction nozzle front end face is provided with the U-shaped shallow depression groove around central through hole.
As preferably: the periphery of described central through hole is provided with uniform 4 axial lead aperture, and be respectively positioned in Rotary-table suction nozzle front end face half area, described U-shaped shallow depression groove also is located in this half area, and at least a part of which has 2 axial lead apertures to be included in described U-shaped shallow depression groove；Described Rotary-table suction nozzle leading section angle is 18.1.
The present invention has simple in construction, easy to use and reliable, and safety is good, it is possible to fix electrical discharge wire easily, it is ensured that the safe handling of wire, and can efficiently control features such as sucking the flow velocity of object and flow.
