Background
The ultrasonic scalpel is widely applied to open type surgical operations and minimally invasive surgical operations, and converts electric energy into mechanical energy of a metal probe (scalpel head) through an energy conversion device, so that the scalpel head can mechanically vibrate at ultrasonic frequency, liquid in tissues is vaporized, protein is solidified, blood vessels are closed, and the effects of cutting and blood coagulation are achieved. Its advantages are accurate cutting, controllable coagulation and no damage to tissue.
The existing ultrasonic knife still has some defects in the using process. Firstly, when the cutter head is vibrated at high frequency to cut blood coagulation tissues, a large amount of heat is generated to vaporize the operation part and surrounding liquid, so that a lens is seriously shielded, the operation is interfered, and the operation efficiency is seriously influenced; secondly, substances generated by vaporization of the ultrasonic knife during operation can be condensed on the lens, other proteins, blood and tissue particles can be adhered to the laparoscope lens, and the laparoscope is taken out and wiped every few times of operation, so that the operation efficiency is greatly reduced; thirdly, smoke generated by vaporization of the ultrasonic knife and tissue particles in an operation area are also condensed and adhered to the ultrasonic knife head, the knife head is overloaded and shut down if the time is long, and the knife head is frequently cleaned for many times in the actual use process. In addition, the treading type aspirator can cause the pneumoperitoneum of the ultrasonic knife to be too high due to the continuous operation in the operation, and the use is inconvenient.
SUMMERY OF THE UTILITY MODEL
In view of the problems in the prior art, the utility model aims to provide a smoke-resistant and anti-endoscope-fouling novel laparoscope cutting and suction linkage ultrasonic knife which has the advantages of smoke resistance, clear visual field, pollution prevention of a lens, reduction of the number of times of lens wiping, reduction of the number of times of cleaning of a knife head in an operation, reduction of operation time, improvement of operation efficiency and the like, and in addition, an ultrasonic knife suction device is operated intermittently to reduce pneumoperitoneum pressure. Meanwhile, the anesthesia time is reduced, the operation risk is reduced, and the operation cost is reduced.
In order to achieve the purpose, the utility model provides the following technical scheme:
the smoke-resistant and anti-endoscope-dirt laparoscopic cutting suction linkage ultrasonic scalpel is characterized by comprising a handle and a scalpel head part, wherein the scalpel head part comprises a scalpel tip and a scalpel rod, a suction sleeve is sleeved on the periphery of the scalpel rod, and the suction sleeve is detachably connected with the handle; the side wall of one end of the suction sleeve close to the cutter head is provided with an opening, the opening is provided with a suction sleeve air outlet interface, and the suction sleeve air outlet interface is connected with a negative pressure suction device through the handle part.
Furthermore, the negative pressure aspirator is a cutting and suction linkage button control type negative pressure aspirator.

Furthermore, the handle is provided with a piezoelectric ceramic piece.
Furthermore, a cutting and suction linkage button for controlling the cutter head part and suction is arranged on the handle.
Furthermore, the distance between the suction sleeve and the cutter bar is 4-8 mm.
Has the advantages that: the utility model provides a smoke-resistant and anti-endoscope-fouling laparoscope cutting suction linkage ultrasonic knife, wherein a suction sleeve arranged on the ultrasonic knife can absorb smoke generated by tissue gasification due to heat when a knife head performs an operation, and the smoke can shield a lens of an endoscope generally and influence the observation of the endoscope in the operation, so that the operation efficiency is influenced, and the operation time is prolonged. Meanwhile, the intermittent operation suction device effectively reduces the pneumoperitoneum pressure of the ultrasonic knife. The ultrasonic scalpel provided by the utility model can absorb vaporized gas and smoke in the operation while controlling cutting and blood coagulation, so that the times of wiping the endoscope are obviously reduced, the operation time is reduced, and the operation efficiency is improved.
