Wherein, the inside of the hollow head 2 is separated by the partition plate 3 from the lavage chamber 31 and the drainage chamber 32 which are not connected to each other, so that the guiding lavage head structure 10 has the functions of lavage and drainage at the same time, so that the diversion The lavage head structure 10 only needs to be inserted into one incision position in order to achieve the advantages of reducing the risk of surgical infection and saving operation time.

In addition, the volume of the lavage chamber 31 is smaller than the volume of the drainage chamber 32, so that the cleaning liquid has a large impulse when ejected from the irrigating port 211, and the unnecessary body fluid and tissue debris are returned to the drainage chamber 32 when there is a large amount. The space is accommodated, thereby increasing the ease of use of the flow-through lavage head structure 10.

In addition, when the flow-through lavage head structure 10 is in use, the hollow head 2 is often bent adjacent to the nozzle body 1 , so if the diameter of the irrigating port 211 or the drain port 212 at the bend is too large, stress concentration is likely to occur. Deformation and damage. Therefore, the caliber sizes of the plurality of irrigating openings 211 are gradually reduced from the closed end 22 of the end of the hollow head 2 toward the take-up body 1 , and the respective caliber sizes of the plurality of drain openings 212 are also directed to the take-over by the closed end 22 of the end of the hollow head 2 The direction of the body 1 is gradually reduced, so that the hollow head 2 has better structural strength in use to improve the service life of the flow-through lavage head structure 10.

Please refer to FIG. 4, which is another embodiment of the flow guiding type lavage head structure 10 of the present invention. The embodiment of FIG. 4 is substantially the same as the embodiment of FIG. 1 to FIG. 3, but the embodiment and the figure of FIG. The difference from the embodiment of FIG. 1 to FIG. 3 is that the opening direction d1 of each irrigating opening 211 and the peripheral wall 21 have a right angle θ 1 or an acute angle θ 3 , and the opening direction d2 of each drainage opening 212 has a space between the opening wall d 21 and the peripheral wall 21 . Right angle θ 2 or acute angle θ 4 .

Further, as described below, the opening direction d1 of the plurality of lavage ports 211 disposed in the middle and the peripheral wall 21 have a right angle θ1, and the opening direction d1 of the plurality of lavage ports 211 disposed on both sides and the peripheral wall 21 have an acute angle. θ 3; a direction θ 2 between the opening direction d2 of the plurality of drain ports 212 disposed in the middle and the peripheral wall 21, and an acute angle θ 4 between the opening direction d2 of the plurality of drain ports 212 disposed on both sides and the peripheral wall 21 . Thereby, a plurality of irrigation openings 211 and a plurality of drainage openings 212 are radially arranged on the peripheral wall 21 to increase the irrigation area of the irrigation opening 211 and the suction area of the drainage opening 212, thereby improving the flow-through irrigation. The ease of use of the head structure 10.

Referring to FIG. 5, it is another embodiment of the flow guiding type lavage head structure 10 of the present invention. The embodiment of FIG. 5 is substantially the same as the embodiment of FIG. 1 to FIG. 3, but the embodiment and the figure of FIG. The embodiment of FIG. 1 to FIG. 3 differs in that the opening direction d2 of each of the drain ports 212 and the peripheral wall 21 have an acute angle θ 4 .

As described in detail below, each of the drainage opening 212 has an acute angle θ 4 between the opening direction d2 and the peripheral wall 21, so that unnecessary body fluid and tissue debris are returned to the drainage chamber 32 to be subjected to greater resistance to reduce unwanted body fluids. The rate at which the tissue fragments are returned to the drainage chamber 32 allows the cleaning fluid sprayed from the irrigation port 211 to have more time for lavage without being quickly withdrawn from the drainage port 212 to the outside of the wound.

In summary, the structure of the diversion irrigating head of the present invention has not been seen in the same kind of products and is used publicly, and has industrial utilization, novelty and progress, fully conforms to the requirements of the new patent application, and is filed according to the patent law.
