Description
Technical Field
The utility model relates to a medical suction head, in particular to a disposable suction head for microsurgery, belonging to the technical field of medical instruments.
Background
Microsurgery refers to fine operations performed on fine tissues by surgeons using fine microsurgical instruments and suture materials by means of magnification of an operating microscope, such as amputation and limb replantation operations, various free skin flap operations, vascular nerve anastomosis operations and the like. In many microsurgical procedures such as replantation of severed fingers, vascular anastomosis (suturing) is a key operation step. Part of blood vessels are fine like filaments, the diameter of the blood vessels like fingers is only 0.5-0.8 mm, and bleeding points at the anastomotic position must be sucked at any time when the blood vessels are anastomosed. The conventional suction head used clinically at present has the defects of large diameter, easy shielding of operation visual field, thick, long and hard, inflexible operation, and possibility of sucking fine blood vessels like filaments into the suction head and even damaging the lumen of anastomotic blood vessels due to improper control of suction force when blood is sucked from the anastomotic position of blood vessels for a long time. Meanwhile, when too much blood seeps in the lumen of the anastomotic blood vessel, the conventional suction head cannot directly stretch into the blood vessel cavity due to the overlarge pipe diameter of the suction nozzle to suck the bleeding point in time, so that blood embolism can be caused for a long time, blood cannot flow after the anastomosis of the blood vessel is finished, even the situation of blood vessel crisis possibly caused after the operation is finished, the probability of secondary operation is increased, and the economic burden and the pressure in the heart of a patient are further increased. To this end, it would be desirable to develop a suction tip that is more suitable for use in microsurgery.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a disposable suction head for microsurgery, which is flexible to operate, can control the suction force, can extend into the lumen of a blood vessel and is not easy to damage the blood vessel, thereby solving the problems existing in the conventional suction head used in the microsurgery.

Furthermore, in order to form quick and stable connection with the female connector of the suction tube, the male connector of the suction tube of the connecting tube adopts a conical stepped line connector.
When the disposable suction head is used, an operator holds the connecting pipe of the adjusting assembly by one hand, closes the side hole on the connecting pipe by a thumb to flexibly control the suction force of the needle tube, and holds or clamps the grasping handle of the needle tube seat of the suction nozzle assembly by the other hand, so that the needle tube can be operated to aspirate a bleeding point when the microsurgery anastomosis blood vessel. Because the needle tube is made of very fine soft materials and the front end of the needle tube adopts a blunt head design, the operation visual field is not shielded, blood vessels are not sucked into the needle tube to cause blood vessel damage, and the front end of the needle tube can be directly extended into a blood vessel cavity to suck blood out points in time, so that anastomotic blood vessels are prevented from being embolized; because the section of the extension hose is arranged, the needle tube is not restricted by the connecting pipe when being placed for sucking blood, so that the operation is more flexible. Therefore, the disposable suction tip of the present invention is more suitable for use in microsurgery than conventional suction tips.
