However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0033] The terms “first”, “second”, etc. used in this document do not specifically refer to an order or sequence, nor are they used to limit the present invention. They are merely used to distinguish components or operations described with the same technical terms.

[0034] The present invention is related to a design of a tissue pulverizer water knife. In the first aspect, the tissue pulverizer water knife of the present invention is very suitable for pelvic or abdominal or percutaneous minimally invasive surgery, so that doctors can use it to cut, ablate, peel or remove the patient's pelvic or abdominal or percutaneous, etc. The surgical process is fast and simple, the target of resection is more clear and quantitative, the operation time is shorter, the treatment is more reliable, the operation is completely controllable, and there is no physical, chemical, biological and other factors that cause negative damage to the pelvic or abdominal or percutaneous; in the second aspect, the tissue pulverizer water knife of the present invention is also suitable for various other surgical open surgeries.

The endoscope module 3 is connected to the water jet assembly 2, the endoscope module 3 is located on one side of the high-pressure pipeline 12, and the endoscope module 3 corresponds to the water jet assembly 2. One end of the electrocoagulator 4 passes through the endoscope module 3, and the electrocoagulator 4 is located on one side of the water jet assembly 2. When the doctor performs pelvic, laparoscopic, percutaneous, endoscopic or open surgery, first, the doctor holds a tissue pulverizer and a water jet to enter the patient's surgical site, and the endoscope module 3 transmits the image of the patient's surgical site to the external workstation. The doctor and the observer watch the image of the patient's surgical site in real time through the external workstation, which increases the safety of the operation. Then, the external workstation introduces liquid into the pump body 11, and the pump body 11 pressurizes the liquid to a predetermined pressure. The pump body 11 transmits the liquid of the predetermined pressure to the water jet assembly 2 through the high-pressure pipeline 12. The doctor operates the water jet assembly 2 to cut, ablate, peel or remove the tissue at the patient's surgical site. After the cutting, ablation, peeling or removal of the tissue at the patient's surgical site is completed, the liquid stops entering the water jet assembly 2. Finally, the electrocoagulator 4 is connected to an external power supply, and the electrocoagulator 4 starts to work to coagulate and stop bleeding at the patient's surgical site.

[0037] See also Figure 2 In the first embodiment of the present invention, the tissue pulverizer water jet also includes a handle 5, and the handle 5 wraps the water jet assembly 2.

At this time, the liquid inlet pipe 23 is connected to the high-pressure pipeline 12, and the outer pipe 22 is connected. The external workstation introduces liquid into the pump body 11. The pump body 11 pressurizes the liquid to a predetermined pressure. The pump body 11 transmits the liquid of predetermined pressure to the liquid inlet pipe 23 through the high-pressure pipeline 12. The liquid inlet pipe 23 transmits the liquid of predetermined pressure to the scraper 24. The doctor operates the scraper 24 to cut, ablate, peel or remove the cell tissue of the patient's surgical site. After the liquid sprayed by the scraper 24 cuts, ablates, peels or removes the tissue, the liquid becomes waste liquid. The cut, ablated, peeled or removed cell tissue and waste liquid are transmitted to the return pipe 21 through the outer pipe 22. The return pipe 21 transmits the waste liquid to the waste liquid recycling station. No separate liquid output pipe is required, which reduces the economic burden of the patient and reduces the risk of subsequent patient infection. In addition, the water jet component 2 cuts the cell tissue quickly, and the operation time is significantly shortened. The water jet component 2 has the function of cutting the line and synchronously aspirating the cell tissue and waste liquid, and no complications occur. After the cutting, ablation, stripping or removal is completed, the water inlet valve 25 is closed. At this time, the liquid inlet pipe 23 and the high-pressure pipeline 12 are in a closed state, and the outer pipe 22 is in a closed state.
