Description

Technical Field

[0001] The utility model relates to a novel neurosurgery universal suction device head end, belonging to the technical field of medical equipment. Background Art

[0002] Neurosurgery suction device can absorb and separate tissues. It consists of three parts: one is the part for negative pressure suction to receive waste liquid; one is the plastic connecting tube connected to the part for negative pressure suction to receive waste liquid; and one is the metal head of the suction device (i.e. the part that needs to be handheld for operation).

[0003] The front end of the traditional metal suction head is tubular and the cross section is circular, which is still acceptable for simple suction. However, when tissue (especially tumor tissue) needs to be separated by appropriate application of the suction device, this tubular suction head is not conducive to separating the tissue.

[0004] At the same time, when neurosurgery requires the use of an aspirator under a microscope, the thumb is required to press the aspirator slot to adjust the suction force at all times. Because the leading doctor and the assistant sit at a 90-degree angle on both sides of the microscope, when the surgeon needs the assistant to hold the aspirator to help with suction, the angle at which the surgeon presses the aspirator slot is not suitable for the assistant's operation. Since the aspirator plastic tube connected to the tail end has a certain twisting force, if the assistant operates the aspirator by pressing the slot in the same direction as the surgeon, he needs to resist the twisting force of the plastic tube, which makes his hands very easy to fatigue and difficult to operate delicately.

[0005] Therefore, the assistant needs to rotate the tail end of the suction device and the connection of the suction device plastic tube to eliminate the twisting force of the plastic tube. This not only delays the operation process, but also when the suction device is returned to the surgeon, the surgeon needs to repeat the "rotation" action again to eliminate the twisting force, which greatly affects the continuity of the operation.

[0006] Therefore, a novel neurosurgery universal suction device tip is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide a novel neurosurgery universal suction device head end to solve the problems raised in the above background technology.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a novel neurosurgery universal suction head end, comprising a handle, one end of the handle is connected to a suction head body, the suction head body is provided with a suction head end, one end of the handle away from the suction head body is connected to a connector for connecting a suction hose through a connecting tube, and a rotatable connector is connected in series on the connecting tube;

[0009] Among them, the connecting part includes a connecting seat and a joint, a threaded part is fixed on the connecting seat, a rotating head is fixed on the end of the threaded part away from the connecting seat, the rotating head is inserted into the interior of the joint, and a connecting cap is sleeved on the joint, and the connecting cap is connected to the threaded part through internal thread engagement.

[0010] Preferably, at least one sealing ring is provided between the rotating head and the joint, and the sealing ring can ensure the airtightness between the rotating head and the joint without interfering with the mutual rotation between the two.

[0011] Preferably, an annular groove for socketing the sealing ring is opened on the side wall of the rotating head, and the number of the annular grooves corresponds to the number of the sealing rings. When the rotating head is inserted into the joint, the sealing ring is first socketed in the annular groove, and then the rotating head is inserted into the interior of the joint. The setting of the annular groove can prevent the position of the sealing ring from moving and improve the stability of the seal.

[0012] Preferably, anti-slip patterns are provided on the outer walls of the connecting seat and the connecting cap, which can increase the friction between the connecting seat, the connecting cap and the hand, making it easier to twist the connecting seat and the connecting cap relative to each other.

[0013] Preferably, the plug interface of the connector is chamfered to facilitate the insertion of the rotating head into the connector.

[0014] Preferably, the end of the suction head is tapered, and the tapered end is used to facilitate separation of the tissue interface.

[0015] Preferably, a suction channel is provided in the handle, the suction head body, the connector and the connecting tube, a suction port is provided at the tip position and / or the side position of the end of the suction head, and the suction port is connected to the suction channel.

[0016] Preferably, a suction hole groove for adjusting the suction force is provided on the side wall of the handle.

[0017] Preferably, a plurality of annular barbs are provided on the outer wall of the connector to improve the stability of the connecting hose.
