Problems solved by technology

When connecting the tee, it does have a certain effect on eliminating the blockage of the suction device, but it still cannot effectively reduce the damage to human tissue caused by the suction device during operation.
In addition, since there is an additional connecting pipe at the bottom of the suction device, it is inconvenient for the operator to handle the suction device by hand.

Embodiment 1

[0074] The preparation of embodiment 1 aspirator

[0075] Prepare the suction device with stainless steel material, such as figure 1 shown. The specific parameters are as follows:

[0076]

[0077]

[0078] in, figure 2 Shows an enlarged schematic diagram of the convex surface at the top of the attractor 1; image 3 Shows an enlarged schematic diagram of the top side of the attractor 2; Figure 4 An enlarged schematic view of the side of the top end of the aspirator 3 is shown.

Embodiment 2

[0080] Adopt the aspirator 2 described in embodiment 1, without connection flushing tee.

[0081] Result: After multiple surgical tests, the results show that the suction device of the present invention has no obstruction and no tissue damage during the operation, and the hard arc-shaped convex surface is used in the blunt separation and separation of internal organs and tissues by the suction device. It also has a better effect in the application of functions such as detection and blocking.

Abstract

The invention provides an aspirator for an endoscopic surgery. Particularly, the aspirator for the endoscopic surgery comprises a holding portion, a suction tube body portion and a suction tube top end portion, wherein the suction tube top end portion comprises a top end body portion and a top portion convex surface, a top suction hole is formed in the top portion convex surface, and a top-side suction hole is further formed in the suction tube top end portion. Parts of openings of the top-side suction hole are positioned in the top portion convex surface and the other parts of openings are positioned in the side face of the top end body portion, and the top end body portion is optionally provided with top suction holes. The aspirator for the endoscopic surgery is suitable for the endoscopic surgery, particularly for a thoracoscopic surgery, can not only suck effectively, but also can obviously reduce or eliminate tissue damage in a surgery process.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to an aspirator for laparoscopic surgery. Background technique [0002] Aspirator is a commonly used surgical instrument, usually used to suck bleeding or effusion, exudate, pus, and the contents of thoracoabdominal viscera during the operation, so as to make the operation process clear and reduce the chance of contamination. [0003] In recent years, minimally invasive surgery represented by laparoscopic surgery technology has become one of the important directions of medical development. In laparoscopic surgery, the suction device needs to enter the abdominal cavity or chest cavity through a small wound to achieve the function of suctioning fluid and contents. At the same time, it may also be used to deal with the blunt separation of some internal tissues and the exploration of some internal tissues , Block the application of functions such as tissues and organs in the body. ...
