Description
本發明係關於外科器械，尤其是關於用於微創手術的抽吸沖洗器。The present invention relates to surgical instruments, and more particularly to a suction irrigator for minimally invasive surgery.
在微創手術中，需要用抽吸沖洗器來清洗腹腔，以及抽取腹腔中的血漬或小屑肉。由於微創手術中進入人體體內的通道既少而且又小，使用的監測儀器和手術器械的電纜、管線繁多，現有技術的抽吸沖洗器因受產品結構設計或零部件模具開發的限制，其延伸管道中沒有區分抽吸通道和輸液通道，手術時沖洗和輸液與抽吸都是共用通道，在抽吸過程中血液和細胞組織沾附在通道中，造成血液和組織再被混到沖洗液流中並被帶回到體腔內。這一缺陷造成了沖洗液污染，從而不得不進一步吸出沖回體內的血液和細胞組織，重複沖洗與抽吸的過程，浪費了手術時間與沖洗溶液。In minimally invasive surgery, a suction irrigator is needed to clean the abdominal cavity and to extract blood or small debris from the abdominal cavity. Because the access to the human body in minimally invasive surgery is small and small, the cables and pipelines of the monitoring instruments and surgical instruments are numerous. The prior art suction and irrigators are limited by the product structure design or the development of the parts and molds. There is no distinction between the suction channel and the infusion channel in the extension duct. Flushing and infusion and aspiration are common channels during the operation. During the aspiration process, blood and cell tissue adhere to the channel, causing blood and tissue to be mixed into the irrigation solution. The stream is brought back into the body cavity. This defect caused contamination of the rinsing fluid, which necessitated further aspiration of blood and cellular tissue that was flushed back into the body, repeated flushing and aspiration, wasting the operative time and rinsing solution.
現有技術抽吸沖洗器存在以下的問題：Prior art suction rinsers have the following problems:
1、現有技術的抽吸沖洗器因受產品結構設計或零部件模具開發的限制，其延伸管道中沒有區分抽吸通道和輸液通道；1. The prior art suction irrigator is not limited by the product structure design or the development of the component mold, and the suction pipe and the infusion channel are not distinguished in the extension pipe;
2、手術時沖洗、輸液與抽吸都是共用通道，在抽吸過程中血液和細胞組織沾附在通道中，造成血液和組織再被混到沖洗液流中並被帶回到體腔內，重複沖洗與抽吸的過程，浪費了手術時間與沖洗液。2. Flushing, infusion and aspiration are common channels during surgery. During the aspiration process, blood and cell tissue are attached to the channel, causing blood and tissue to be mixed into the flushing fluid stream and brought back into the body cavity. Repeat the process of rinsing and aspiration, wasting the operation time and flushing fluid.
本發明要解決的技術問題在於避免上述現有技術的不足之處而提出一種用於微創手術的抽吸沖洗器。The technical problem to be solved by the present invention is to avoid a deficiencies of the prior art described above and to propose a suction irrigator for minimally invasive surgery.

When the subject collects the specimen, the instrument can enter unobstructed.

Between the seal B and the seal C. When sucking, it is necessary to press the suction handle 33 while relaxing the infusion handle shank 43 and sucking the handle 33. When pressed, the movable suction duct 32 is directed toward the duct body 20 by the suction handle 33. Moving, at this time, the opening 321 at the bottom end of the movable suction pipe 32 is connected to the waste liquid pipe 36. At this time, the liquid suction passage is opened, and the waste liquid after flushing in the body passes through the suction pipe 102, the pipe main body 20, and then wastes. The liquid outlet 21 flows through the suction duct chamber 31, and due to the presence of the seal ring A, the liquid in the suction duct chamber 31 can only flow through the movable suction duct 32 through the opening 321 of the bottom end thereof, and finally the liquid is discharged from the waste liquid. The duct 36 is discharged.
未按壓抽吸按柄33時，廢液管道36與抽吸管道室31的接口被局限在密封圈A與密封圈B之間的密封空間內；按壓抽吸按柄33時，廢液管道36與抽吸管道室31的接口被局限在密封圈B與密封圈C之間的空間內。When the suction handle 33 is not pressed, the interface of the waste liquid pipe 36 and the suction duct chamber 31 is confined in the sealed space between the seal ring A and the seal ring B; when the suction handle 33 is pressed, the waste liquid pipe 36 The interface with the suction duct chamber 31 is confined within the space between the seal ring B and the seal ring C.
