Embodiment 1

[0029] refer to figure 1 , figure 2 and image 3 , a surgical instrument for laparoscopic surgery with a suction function. During the operation, it is only necessary to open a hole less than 15 mm above the patient's abdominal cavity, which minimizes the trauma to the patient and facilitates the patient's later recovery. The body 1 is placed on the hole, and the top of the cylinder 1 is provided with a positioning column 4, which can be used to insert an ultrasonic knife, laparoscopic endoscope, gallbladder grasping forceps, monopolar electric knife, etc., to perform operations on patients For operation, there is a guide tube 3 under the cylinder body 1, which is used to insert into the hole and prop up the hole to facilitate the entry of medical tools; the deflector includes a connector 6 and a The extension rod 605 fixed under the connecting head 6 extends into the cylinder body 2, and the drainage tube 7 is arranged on it. On the one hand, the abdominal cavity can be pro...

Abstract

The invention discloses a surgical instrument with an aspirator function for laparoscopic surgery, and belongs to the technical field of medical instruments. The surgical instrument with the aspirator function for the laparoscopic surgery comprises a first cylinder, wherein a positioning column is arranged on the upper portion of the first cylinder, and a guide cylinder is arranged on the lower portion of the first cylinder; a fluid director which comprises a connector and an extension rod fixed below the connector, the extension rod is provided with a drainage cylinder, and the extension rod is arranged on the first cylinder body; and a second cylinder which is composed of a hollow column body and a clamping sleeve and arranged in the first cylinder, wherein when the column body slides downwards in the first barrel body, the clamping sleeve extends out of the guide barrel and extends towards the outer side of the guide barrel. The safety of the operation process is improved, operation wounds are reduced, effusion in the abdominal cavity can be adsorbed in time, image collection of an endoscope is not affected, and the efficiency and safety of the abdominal cavity operation work are greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical instrument for laparoscopic surgery with an aspirator function. Background technique [0002] With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, endovascular surgery has gradually developed, greatly increasing the surgical options for patients. . Compared with traditional open surgery, laparoscopic surgery avoids long incisions and helps patients recover. In addition, in laparoscopic surgery, the laparoscopic lens can provide doctors with a wider and clearer field of vision, which is conducive to the doctor to complete the operation more smoothly and reduce the risk of surgery. As a minimally invasive surgery, laparoscopic surgery is currently very universal. ...
