Description

Suction device with piercing core

technical field

The utility model relates to the technical field of aspirator equipment, in particular to a device with a puncture inner which is convenient to puncture into a cyst cavity, can be sucked without pulling out an inner core, has a retractable inner core, avoids cyst fluid leakage, is convenient to operate, and has a simple structure. core attractor.

Background technique

The removal of accumulated blood or fluid in surgical operations, holding the broken end of a ruptured blood vessel, suctioning sputum in clinical first aid, and artificial abortion in gynecological operations are all inseparable from suction devices. The suction device is used to suck the contents of bleeding, exudate, pus, and chest viscera during the operation, so as to make the operation clear and reduce the chance of contamination. The principle of the aspirator is very simple, that is to create the negative pressure state of its suction head through a certain method, so that the atmospheric pressure will squeeze the material outside the suction head to the suction head, thus completing the "attraction" effect.

Most of the existing laparoscopic negative pressure suction devices are hollow instruments with a blunt front end, which are used to suck blood, cystic fluid and other liquids in the laparoscopic operation area, so as to facilitate the operation. During laparoscopic treatment of cystic lesions, it is sometimes necessary to open the cyst and aspirate the cystic fluid. The disadvantages of the existing equipment are as follows: 1. The front end of the aspirator is blunt, and it is difficult to puncture into the cyst cavity. It is necessary to use electric hooks, ultrasonic scalpels and other energy equipment to assist, and insert the aspirator after opening the cyst. 2. When the energy device opens the cyst, if the hole is too small, it is difficult for the suction device to enter, and after the cyst is opened, the cyst fluid leaks out, and it is difficult for the energy device to further open the cyst cavity. 3. When the energy device opens the cyst, if the hole is too large, the aspirator may not be able to fill the hole after the suction device is inserted, causing the cyst fluid to leak into the abdominal cavity. When the cyst fluid is pus, it may lead to dissemination of inflammation, leading to severe infection and even septic shock, which is life-threatening. When the cyst fluid is cancerous, it may lead to tumor dissemination, resulting in rapid tumor progression and metastasis, which seriously affects the prognosis of patients.

There is a need for an aspirator with a puncture inner core which is convenient to puncture into the cyst cavity, can be sucked without pulling out the inner core, has a retractable inner core, avoids leakage of cystic fluid, is convenient to operate, and has a simple structure.
