[0023] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Example

[0025] Please refer to Figures 1 to 4 As shown, the present embodiment provides a water-sprayable laparoscopic electric knife, comprising: an electric knife handle 1, the electric knife handle 1 having an electric knife head 2 for laparoscopic surgery, a cleaning tube 3 and a liquid extraction tube 4 fixedly installed inside the electric knife handle 1, and both ends of the cleaning tube 3 and the liquid extraction tube 4 extend from the ends of the electric knife handle 1 respectively; wherein, the cleaning tube 3 and the liquid extraction tube 4 are located at one end of the electric knife head 2 and are respectively installed with tube length adjustment components, and by simultaneously installing the cleaning tube 3 and the liquid extraction tube 4 inside the electric knife handle 1, it is possible to facilitate the cleaning of the patient's wound, keep the wound clean, and further improve the efficiency of the operation.

[0026] Among them, the tube length adjustment component includes a connecting tube 5, a first external thread 51 is provided on the outer wall of one end of the connecting tube 5, and an internal thread 6 is respectively provided on the inner wall of one end of the cleaning tube 3 and the liquid extraction tube 4. The two connecting tubes 5 are threadedly connected to the cleaning tube 3 and the liquid extraction tube 4 respectively. By installing the connecting tubes 5 at the ends of the cleaning tube 3 and the liquid extraction tube 4 respectively, the connecting tube 5 can control the use length of the cleaning tube 3 and the liquid extraction tube 4 to avoid the cleaning tube 3 and the liquid extraction tube 4 being too long to affect the use effect of the electric knife head 2. In addition, the lengths of the cleaning tube 3 and the liquid extraction tube 4 are adjusted to facilitate the positioning and flushing of the cleaning tube 3 and the positioning and drainage of the liquid extraction tube 4, and facilitate operation.

[0027] Among them, one end of the connecting tube 5 has a rounded edge 53 structure, which reduces the wear on the contact part when the connecting tube 5 contacts the patient's wound during the process of extracting fluid or cleaning, thereby increasing the practicality of the water-jet laparoscopic electrosurgical unit.

[0028] Among them, an anti-slip pattern 52 is integrally formed on the outer wall of one end of the connecting tube 5. By providing the anti-slip pattern 52 on the connecting tube 5, the connecting tube 5 can be easily twisted, and the use length of the connecting tube 5 can be adjusted conveniently, which is convenient for operation.

[0029] Among them, a second external thread 7 is respectively provided on the outer wall of one end of the cleaning tube 3 and the liquid extraction tube 4. The second external thread 7 of the cleaning tube 3 and the liquid extraction tube 4 is used to connect an external pipeline, which is convenient for disassembly, cleaning and replacement. The external pipeline is a hose, which is convenient for the operation and use of the laparoscopic electric knife.

[0030] Among them, the hand-holding part of the electric knife handle 1 is fixedly installed with an anti-skid convex strip 8, which can increase the stability of the hand-held electric knife handle 1 and prevent the electric knife handle 1 from slipping during surgery, which is helpful for the use of the laparoscopic electric knife.

[0031] Among them, the cleaning tube 3, the liquid extraction tube 4 and the connecting tube 5 are all hard tube structures. When the liquid extraction tube 4 is sucking back the waste liquid, the negative pressure will not cause the liquid extraction tube 4 and the connecting tube 5 to deform and shrink, which can ensure the normal and smooth use of the cleaning tube 3, the liquid extraction tube 4 and the connecting tube 5.

[0032] It is worth mentioning that one end of the liquid extraction pipe 4 and the cleaning pipe 3 with the second external thread 7 is respectively connected to a delivery pump, through which the cleaning liquid is delivered and the cleaning waste liquid is discharged. The connection method and principle of the delivery pump here are both existing technologies and will not be repeated here.

[0033] Working principle: When in use, first connect the end of the cleaning tube 3 with the second external thread 7 to the liquid outlet pipe of the cleaning pump, and then connect the end of the cleaning tube 3 with the second external thread 7 to the liquid inlet pipe of the drainage pump, and then laparoscopic surgery can be performed;

[0034] During laparoscopic surgery, when bleeding at the surgical site causes blurred vision and makes the surgery difficult, the cleaning pump is started to spray cleaning fluid from one end of the cleaning tube 3 to clean the patient's wound. The waste liquid after cleaning is recovered and discharged through the liquid extraction tube 4 connected to the drainage pump to keep the wound clean.

[0035] When the cleaning tube 3 is in use, the connecting tube 5 at one end of the cleaning tube 3 is rotated so that the use length of the connecting tube 5 exceeds the length of the electric knife head 2, so that the liquid outlet end of the connecting tube 5 is conveniently directed toward the patient's wound for cleaning;

[0036] When the liquid extraction tube 4 is in use, the connecting tube 5 at one end of the liquid extraction tube 4 is rotated so that the use length of the connecting tube 5 exceeds the length of the electric knife head 2, and the liquid suction end of the connecting tube 5 is immersed in the waste liquid to suck and discharge the waste liquid.

[0037] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
