Problems solved by technology

At the same time of dredging, the patient's wound is likely to overflow blood again, causing the doctor's vision to be blurred and unable to perform the operation. The operation can only be continued after it is sucked away, which not only prolongs the operation time, but also seriously affects the doctor's mood and reduces the quality of the operation

Embodiment Construction

[0037] The present invention aims to propose a new type of diversion head, which can more conveniently and quickly realize dredging when it is blocked by blood, bone residues and fragmentary tissues, thereby shortening the operation time, reducing the emotional fluctuations of doctors, and improving quality of surgery.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] like Figure 1-Figure 4 As shown, the main difference between the diversion head provided by the embodiment of the present invention ...

Abstract

The invention discloses a diversion head. The diversion head comprises an inner adsorption pipe with an inner tube suction hole, and an outer adsorption tube arranged in the inner adsorption tube in a sleeving mode. The opening area of the inner tube suction hole is smaller than the sectional area of the inner adsorption tube. An outer tube suction hole is formed in the outer adsorption tube. The outer adsorption tube and the inner adsorption tube can relatively rotate to achieve the purpose that the position, relative to the outer tube suction hole, of the inner tube suction hole is switched between an aligned state and a dislocated state. Compared with an original diversion tube needing to be dredged through an iron wire, a diversion head can be dredged without other tools, the dredging efficiency is high, the dredging effect is good, operation is easy, convenient and quick, time spent on dredging operation is shortened, operation time is shortened, emotional fluctuation of a doctor is relieved, and operation quality is improved. The invention further provides a suction device with the diversion head.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a flow guide head, and also relates to a suction device with the above flow guide head. Background technique [0002] At present, during surgical operations, blood, bone residues, and fragmentary tissues in the wound are usually sucked out in time by using a suction device, so as to avoid interfering with the doctor's operation. The working principle of the suction device is to make the diversion head in a negative pressure state (the general method is to make the diversion head have an adsorption airflow), so that the atmospheric pressure will squeeze the material outside the diversion head into the diversion head, thereby realizing attraction effect. [0003] In the prior art, the diversion head of the aspirator is a common diversion tube. When the aspirator is working, an adsorption airflow will be generated in the diversion tube, and the suction end of the diversio...
