Description

Irrigation suction tube and surgical device

Technical Field

Background

With the rapid development of medical technology, people not only require surgery to cure diseases, but also want to reduce the damage to patients caused by the surgery itself, and realize micro non-invasive surgery, such as laparoscopic surgery, and need to establish a surgery channel through a puncture outfit on the abdominal wall or even the back of a patient to reduce the damage to the patient. Laparoscopic surgery is a highly instrument-dependent procedure in which the application of energy instruments, such as monopolar, bipolar, etc., is indispensable in surgical cutting, hemostasis, etc.

At present, most energy instruments adopt heat energy or mechanical energy of high-speed and low-frequency oscillation to cause protein denaturation, and in the process, a large amount of smoke is generated. Problems with smoke generation: 1. affecting the safety of the operation: a large amount of smoke obstructs the operation visual field, so that the operation area is blurred, and the operation safety is influenced; 2. the continuity of the operation is influenced, the operation time cost is increased, the operation is sometimes required to be suspended, and the operation can be continued after the smoke is dissipated and the operation visual field is clear; 3. potential health hazards to the patient undergoing the procedure, the doctors and nurses involved in the procedure: surgical smoke contains a variety of harmful chemical components (organic or inorganic compounds), even carcinogens, and scholars have found at least 4 specific carcinogens in surgical smoke: 1, 3-butadiene, hydrogen cyanide, acetylene and organic benzene, wherein smoke can be absorbed by serosa and peritoneum on the inner wall of the abdominal cavity and the surfaces of viscera of a patient, and researches show that in urine of a patient subjected to laparoscopic surgery, the detected benzene and toluene are obviously increased, so that the urine is not beneficial to postoperative rehabilitation and even has potential harm to the health of the patient; 4. harm to the health of the operating doctor: in addition to the above mentioned harmful or carcinogenic substances, surgical smoke can also produce strong peculiar smell and infectious biological particles, and it has been reported that the harmfulness of smoke produced by electrosurgery treated 1g of human tissue is equivalent to 6 unfiltered cigarettes inhaled by human body. The harmful quality of the smoke generated by one operation is equivalent to the harmful smoke generated by 27 to 30 cigarettes. 77% of surgical smoke particles are less than 1.1um, have an average diameter of only 0.07um, and also contain some ultra-fine particles, with an average diameter of 10nm to 1um, although a surgical mask is tight-fitting, particles smaller than 5um can be inhaled directly through the mask into the lungs. In addition, harmful substances (styrene, teratogen, etc.) can directly enter the body through eyes, etc., causing damage to the human body. Moreover, in laparoscopic techniques, the lens of the laparoscope is typically contaminated with peritoneal or other body fluids, blood, aerosol fat, tissue particles, smoke, debris, or condensation, which can affect the field of view of the physician (via an external monitor).

Therefore, how to effectively discharge or eliminate the smoke generated by the energy instrument during operation, quickly clean the lens of the endoscope and ensure the safety and continuity of the operation is a technical problem to be solved in the field of related researches of the surgery.

In particular embodiments, the first smoke evacuation structure 14 may be an opening, as shown in fig. 12, which may be a recess formed by a proximal depression of the mouthpiece structure of the tube body 1, or, as shown in fig. 14, the opening may be another structure, such as a circular or rectangular aperture. In addition, referring to fig. 13, the nozzle structure of the tube body 1 is an outer cone structure, and the outer cone structure is a structure whose outer contour is a conical surface gradually increasing from the far side to the near side as shown in fig. 14, so that the shielding of the head of the surgical instrument can be reduced, the endoscopic observation is facilitated, and the insertion of the puncture device is smoother. Wherein, the inner contour of the outer cone structure is a conical surface 18 with gradually increasing circumference from the far side to the near side, thereby facilitating the smooth insertion of surgical instruments; the distal end opening of the outer cone structure is provided with a chamfer 19, which is convenient for the surgical instrument to smoothly exit.
