Description

Palm-head laparoscope aspirator

Technical Field

The utility model belongs to the technical field of laparoscopic attractors, and particularly relates to a laparoscopic attractor with a palm-shaped attraction head.

Background

Laparoscopic surgery is a newly developed minimally invasive procedure, and is currently widely performed. Along with the rapid progress of industrial manufacturing technology, the fusion of relevant disciplines lays a firm foundation for developing new technologies and new methods, and doctors are more and more skilled to operate, so that a plurality of past open surgeries are replaced by endoscopic surgeries at present, and the surgical wounds are greatly reduced.

In the laparoscopic surgery process, an aspirator is usually used for helping to suck bleeding and keep the surgical field clear, and the aspirator is matched with a push baffle to expose the wound surface, so that the aspirator plays an irreplaceable role in the smooth completion process of one surgery. However, the conventional aspirator is in a straight tube shape of simple metal, only the head end is provided with an aspiration hole, the friction force is insufficient, the slipping occurs in the process of frequent pushing and blocking, the aspiration hole is a single large hole, the blood clot accumulation and blocking are easy to occur, and the aspirator can be used after being dredged again, so that the operation time is prolonged.

In order to overcome the above-mentioned drawbacks, many beneficial researches have been carried out in the prior art, for example, CN216294004U discloses a laparoscopic aspirator with anti-blocking and blunt-force separation functions, which comprises an aspiration tube, one end of the aspiration tube is an aspiration port, the other end of the aspiration tube is provided with an aspirator interface connected with a negative pressure aspirator, and a valve for controlling the opening and closing of the aspiration tube is arranged on the aspiration tube. In order to realize anti-blocking and increase friction force with tissues, a hollow anti-blocking sleeve made of rubber is connected to the suction port, an arc-shaped sponge filter layer is arranged at the end part of the hollow anti-blocking sleeve, which is far away from the suction pipe, and a plurality of side holes are formed in the part, which is close to the suction pipe.

When the device is adopted to carry out effusion suction in the laparoscopic surgery process, the effusion in the patient can flow into the suction tube from the side hole on one hand and flow into the suction tube through the filter layer on the other hand; meanwhile, the anti-blocking sleeve is made of rubber materials, so that the friction force is high, and the tissue can be easily lifted for separation when the tissue is separated; because the end of the filter layer is arc-shaped, after the suction tube is inserted into a human body, the arc-shaped filter layer is in softer contact with human tissues, so that the puncture or scratch of the tissues is avoided.

Although the above devices, to some extent, prevent clogging, the drawbacks are also evident: (1) The device only relies on the side opening on the anti-blocking sleeve pipe and the adsorption of the sponge filtering adsorption layer to realize the suction of effusion, and when the effusion is too big, the condition that can't timely suck out easily appears. Once the sponge is adsorbed and saturated, only the side holes can be relied on, so that the attraction efficiency is necessarily affected; (2) The pore diameter of the side hole is small, so that the side hole is more easily blocked by tissue fragments or blood clots, and compared with a single-side large hole in the prior art, the side hole is more difficult to clean after the side hole is blocked, and the operation progress is easily delayed; (3) Once the sponge filter layer is absorbed and coagulated, the sponge filter layer can be blocked by a hundred percent, and is difficult to clean, so that the sponge filter layer has no practicability.
