Embodiment Construction

[0017] Combine below figure 1 and figure 2 The present invention is described in detail, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not as a limitation to the present invention.

[0018] The suction head of the aspirator for abdominal surgery includes a tube body 1 connected to the negative pressure tube 3 of the suction device, and a liquid outlet chamber 13 is formed at the rear end where the tube body is connected with the negative pressure tube, and the tube body can The tube wall of the front end extending into the abdominal cavity is provided with several grooves 2 along the length direction of the tube body, so that the grooves at the front end 12 of the tube body have openings on the outer wall to facilitate the passage of waste blood and waste residue; each groove It communicates with the liquid outlet cavity 13 at the rear end 11 of the tube body. During implementation, the negative pressu...

Abstract

The invention relates to a medical instrument, in particular to a suction head of an aspirator for abdominal operation, which comprises a tube body connected with a negative pressure tube of the aspirator, and a liquid outlet cavity formed at a rear end of joint between the tube body and the negative pressure tube, the tube body can extend into the tube wall of the front end of the abdominal cavity and is provided with a plurality of grooves along the length direction of the tube body, and each groove is communicated with the liquid outlet cavity at the rear end of the pipe body. According tothe invention, the front end of the tube body is provided with a groove, when a negative pressure is provided at the rear end of the tube body, the waste blood and the waste residue in the operation are attracted to the inner cavity of the rear end through the groove at the front end, and since the groove opening is long, compared with the various pores of the existing suction head, the waste blood and the waste residue can be easily passed, and the phenomenon of blockage can be prevented.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a suction head of a suction device for abdominal surgery. Background technique [0002] In recent years, with the rapid development of medical device technology and the continuous improvement of surgical concepts, the proportion of laparoscopic surgery has accounted for more than half of surgical operations. Usually, almost all general surgical operations, such as liver, gallbladder, pancreas, spleen, gastrointestinal tumor surgery, abdominal wall hernia repair, etc., as well as various genitourinary system operations such as kidney, prostate, bladder tumor surgery, hysterectomy, etc. It can be completed under laparoscopy; the principle is to establish a number of operating holes through the patient's abdominal wall, and after the artificial pneumoperitoneum is established, a laparoscopic lens with a cold light source and a long rod-shaped laparoscopic operating instrument rod ...
