Problems solved by technology

[0003] However, in the prior art, the water pipe (suction tube and / or flushing tube) of the laparoscopic flushing aspirator is a long straight pipe, and there are the following problems in use: one is that the front end of the flushing aspirator is affected due to the rearward position of the flushing aspirator The alignment of the nozzle and the abdominal incision prolongs the insertion operation time, and both hands are required to hold it; the second is that when inserting or withdrawing, the medical staff is forced to move and shift, thereby increasing the work intensity of the medical staff and affecting the standing of other medical staff. Third, since the operation switch is set at the holding part, the doctor who operates the knife cannot use the flushing suction device at the same time, and can only be handled by others, which affects the operation process and use efficiency
Above-mentioned these situations all can bring operational inconvenience to the doctor in operation

Embodiment 1

[0031] Such as figure 1 As shown, a laparoscopic flushing suction device includes a control valve 1 and a water pipe connected to the control valve 1 through a connecting pipe 2. The control valve 1 is respectively provided with a flushing interface 101 and a suction interface 102. The water pipe includes The inner tube 3 and the telescopic sleeve 4 sleeved on the outside of the inner tube 3 can make the sleeve 4 extend outward or shorten inward relative to the inner tube 3; the inner tube 3 is stretched by tension The nut 5 is fixedly connected with the connecting pipe 2, so that the inner pipe 3 and the connecting pipe 2 can be fixedly connected only by rotating the tensioning nut 5, and the operation is convenient and reliable; The positioning mechanism I that is fixedly connected to the nut 5 and the positioning mechanism II that can be fixedly connected to the front end of the inner tube 3; The housing groove 501 of a piece (not shown), so that it can be plugged and fixe...

Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that the positioning mechanism II includes a tapered section (not shown) arranged at the tail end of the casing 4 and a bell mouth section (not shown) arranged at the front end of the inner tube 3, The inner wall of the tapered section has the same cross section as that of the outer wall of the bell mouth section, and the two are through interference fit. In this way, only the sleeve pipe 4 needs to be stretched outward relative to the inner pipe 3, so that the inner wall of the tapered section can be matched with the outer wall of the bell mouth section of the inner pipe 3, so that it is fixedly connected to the front end of the inner pipe 3, and the operation is convenient and fast. , there is no need to rotate the casing 4, and at the same time cooperate with the positioning mechanism I to realize the linear movement of the casing 4 when the inner tube 3 expands and contracts.

Embodiment 3

[0039] Such as figure 2 As shown, the difference between this embodiment and the above-mentioned embodiment is that: the inner tube 3 is two, including a flushing tube 301 and a suction tube 302 arranged side by side and at a certain distance from each other. The flushing port 101 of the control valve 1 communicates, and the suction pipe 302 communicates with the suction port 102 of the control valve 1; the flushing pipe 301 and the suction pipe 302 have the same shape and size, and their cross-section is a D-shaped structure. The flushing pipe 301 and the suction pipe The straight sections of the D-shaped structural section of 302 are relatively arranged. The D-shaped structure not only enables the irrigation tube 301 and the suction tube 302 to be placed in the cannula 4, but also maximizes the flushing when the inner cavity capacity of the cannula 4 is certain. The pipe diameters of the tube 301 and the suction tube 302 ensure that the flushing aspirator obtains good flush...

Abstract

The invention discloses a laparoscopic flushing aspirator, which belongs to the technical field of medical devices and comprises a control valve and a water pipe connected to the control valve through a connecting pipe. Telescopic sleeve, the inner tube is fixedly connected with the connecting pipe through a tension nut; the flushing suction device also includes a positioning mechanism I that can be fixedly connected with the tension nut at the tail end of the sleeve and a fixed connection with the front end of the inner tube. Positioning mechanism II; the positioning mechanism I includes an accommodating groove for an assembled seal on the tension nut and on the end surface opposite to the tail end of the casing, and the tail end of the casing is sealed and connected in the accommodating groove in the slot. The present invention decides whether to stretch and extend the casing according to needs, and its shortening and elongation are simple and convenient, and the positioning sealing effect is good, and it has the advantages of simple structure, easy operation, reasonableness, ingenuity, convenient operation and reliability.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to a laparoscopic flushing aspirator. Background technique [0002] With the advancement of science and technology, laparoscopic surgery has developed greatly, and laparoscopy with minimally invasive effects plays an important role in the treatment and diagnosis of celiac diseases. Laparoscopic surgery is popular among patients because of its advantages of small incision, less pain, faster recovery, and less postoperative scar. In laparoscopic surgery, medical personnel have to complete a series of actions, including cutting and stripping, electrocoagulation to stop bleeding, flushing, blood sucking, etc. Among them, peritoneal washing must be performed during the operation, and then the lotion is sucked away. [0003] However, in the prior art, the water pipe (suction tube and / or flushing tube) of the laparoscopic flushing aspirator is a long straight pipe, and there are...
