Abstract
The invention relates to a multilevel sealed medical puncture needle which is mainly suitable for abdominal cavity examinations and an abdominal cavity surgery. Seal rings, straight sealing caps, O-shaped rings and non-resistance seal rings are sequentially arrayed along the center line of an outer tube. After the outer tube is matched with a main body, the outer tube and the main body are sealed through the seal rings, and pressing caps and the main body are welded and then fixed through the straight sealing caps in sealing mode. Clamping caps and the pressing caps are matched and then sealed through the O-shaped seal rings, the pressing caps and the clamping caps are welded and then fixed through the non-resistance seal rings in a sealing mode, and a puncture cone is matched with the outer tube and then sealed through the non-resistance seal rings. Each non-resistance seal ring comprises crumple-shaped thin films and a shooting-type core disc. Each whole non-resistance seal ring is in an integral structure formed in a one-time mode. The multilevel sealed medical puncture outfit is reasonable in design, due to the non-resistance seal rings, the situation that the puncture outfit can move left and right without resistance and not leak when moving front and back in the process of puncturing can be guaranteed, therefore the gas tightness of the puncture needle is guaranteed and the situation that the puncture outfit freely moves in a puncture sleeve is guaranteed.
Description
Technical field
The present invention relates to a kind of puncture needle, a kind of multi-stage sealed puncture needle particularly, it mainly is applicable to the abdominal paracentesis to patient, in order to check and perform the operation, belongs to medical apparatus and instruments.
Background technology
According to clinical response, in operation, the quality problems that puncture needle is maximum are that gas leakage and operating theater instruments can not move freely in puncture casing, in the time of will causing like this operation, abdominal pressure is inadequate, the abdominal cavity is expanded insufficient, causes the visual field unclear, and operative space is insufficient, bring inconvenience to operation, and can affect to operation.
China Patent No. 2008100602142 discloses the patent of invention that a kind of name is called " magnetic ball sealing novel puncture device ", and it is mainly used in solving existing easily aging, the easy defective of gas leakage and complex structural designs of silica gel sealing.Although the structural design of this magnetic ball sealing is simpler, it in use operating theater instruments resistance in puncture but easily occurs and becomes large, and feel variation when causing the doctor to use operating theater instruments is brought inconvenient shortcoming to operation.
The puncture needle that also has some other structures, but these puncture needles all do not design the non-resistance sealing ring, can not guarantee the unresisted movement in apparatus left and right in puncture, can not guarantee when apparatus moves forward and backward in puncture air tightly, namely can not guarantee air-tightness and operating theater instruments the moving freely in puncture casing of puncture needle.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, and provide a kind of structural design more rational multi-stage sealed puncture needle, it can guarantee the unresisted movement in apparatus left and right in puncture, and can guarantee when apparatus moves forward and backward in puncture air tight, thereby guaranteed air-tightness and operating theater instruments the moving freely in puncture casing of puncture needle.
The present invention addresses the above problem the technical scheme that adopts: this multi-stage sealed puncture needle comprises the outer tube, gland, card cap, pressure cap, main body of hollow and with the puncture awl of needle body, main body, card cap, gland, puncture awl rear portion is arranged in order according to the centrage of outer tube, it is characterized in that:
Also be provided with sealing ring, O type circle, non-resistance sealing ring and a word sealing cap, described sealing ring, a word sealing cap, O type circle, non-resistance sealing ring are arranged in order according to the centrage of outer tube; Guarantee the air-tightness of puncture needle in operation by sealing layer by layer.
Described outer tube and main body seal by sealing ring after coordinating, fixing by a word sealing cap sealing after pressure cap and main body welding, after coordinating, card cap and pressure cap seal by O type circle, pass through the sealing of non-resistance sealing ring after gland and the welding of card cap fixing, seal by the non-resistance sealing ring after puncture awl coordinates with outer tube; In order to guarantee simultaneously the air-tightness of puncture needle and the motility of operation.
The center of described non-resistance sealing ring is a through hole, and this non-resistance sealing ring comprises wrinkle shape thin film and emission core dish, and whole non-resistance sealing ring is an one-time formed overall structure; Make thus the needle body of the present invention can unresisted movement, and air tight when mobile; Simultaneously, one-time formed overall structure has also guaranteed the sealing property of sealing ring.
Wrinkle shape thin film of the present invention is distributed in the periphery of emission core dish, and described emission core dish is positioned at the centre of non-resistance sealing ring, and this emission core dish is a projective structure, and it is comprised of the core dish elastica that evenly is scattered in umbrella with several; Make thus the unresisted movement in the present invention left and right in puncture, and air tight can guarantee apparatus moving forward and backward in puncture the time, be the optimum structure of non-resistance sealing ring; The projective structure of emission core dish also has the effect of resistance to compression muscle.
Non-resistance sealing ring of the present invention is made with the PVC plastics.In order to realize better purpose of the present invention.
The present invention compared with prior art, have the following advantages and effect: structural design is more reasonable, sealing property is better; Due to the non-resistance sealing ring that is designed with special construction and shape, the periphery of this non-resistance sealing ring is comprised of thin film, guarantees the unresisted movement in apparatus left and right in puncture; The centre of non-resistance sealing ring forms by a projection and by certain thickness core dish elastica, and is air tight when the assurance apparatus moves forward and backward in puncture, thereby guaranteed that the air-tightness of puncture needle and operating theater instruments can move freely in puncture casing; The one-time formed overall structure of non-resistance sealing ring has also guaranteed the sealing property of sealing ring, and its longer service life.
