Problems solved by technology

[0004] The purpose of the present invention is to provide an aspirator with a clamping function to solve the problem in the above-mentioned background art that due to the narrow neurosurgery channel, it is difficult to realize the ideal operation mode of "suctioner+clamping device+separating device". As well as the problems of long operation time and increased bleeding caused by the poor cooperation of the assistant during the operation and the waiting for the assistant's instrument to enter the deep space

Embodiment 1

[0038] For content that only needs to be adsorbed.

[0039] When in use, the first connecting handle 11 or the second connecting handle 18 is threadedly connected to the connection port 1 through the first threaded connecting rod 17 or the second threaded connecting rod 22, and then through the first joint 15 or the second connecting handle. The function of the two joints 20 is to connect the first connection handle 11 or the second connection handle 18 to the negative pressure equipment, then extend the suction tube 2 through the narrow surgical channel to the vicinity of the tissue or liquid to be sucked, and then through the effect of negative pressure The blood or tissue fluid that blocks the field of view is sucked away, or the treatment object is adsorbed at the end of the suction tube 2, which facilitates the treatment of the treatment object by the attending doctor. At the same time, the first threaded connecting rod 17 and the first connecting handle 11 are fitted wit...

Embodiment 2

[0041] For the content that needs to be adsorbed and clamped at the same time.

[0042]When in use, the first connection handle 11 or the second connection handle 18 is threadedly connected to the connection port 1 through the first threaded connection rod 17 or the second threaded connection rod 22, and then through the first joint 13 or the second connection handle. The function of the two joints 20 is to connect the first connection handle 11 or the second connection handle 18 to the negative pressure equipment. Then extend the suction tube 2 through the narrow surgical channel to the vicinity of the tissue to be sucked and clamped, and then absorb the blood or tissue fluid that blocks the view through the negative pressure, and at the same time absorb the treatment object on the end of the suction tube 2, and then When the movable handle 8 shrinks to the fixed handle 1, the connecting rod 14 is driven to rotate clockwise around the positioning pin 15, thereby driving the s...

Abstract

The aspirator with the clamping function comprises a connecting port, a suction tube and a tensioning rod are arranged in the connecting port, a clamping assembly is arranged at the tail end of the suction tube in a sleeving mode, a reset spring is arranged between the clamping assembly and the suction tube in a sleeving mode, one end of the tensioning rod is connected to the clamping assembly, and the other end of the tensioning rod is connected to the clamping assembly. The other end of the tensioning rod is connected to a push-pull mechanism, a movable handle is arranged on the outer side of the push-pull mechanism, and a connecting handle is connected to the outer side of the connecting opening. When the aspirator with the clamping function is used, not only can contents be effectively adsorbed, but also fixing and clamping can be carried out. And the suction force can be adjusted while adsorption is performed. And after the use is finished, the reset work can be carried out under the action of the reset spring. The whole operation is simple, the adsorption clamping efficiency is high, the difficulty and risk of an operation are reduced, and the efficiency of the operation is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an aspirator with a clamping function. Background technique [0002] In neurosurgery, the operator's normal operating mode is to hold the suction device in the left hand and operate with bipolar coagulation or other instruments in the right hand. The aspirator absorbs the bleeding in the surgical field and reveals the tissue structure of the site to be treated, which is of great significance for neurosurgery to achieve the goal of minimally invasive neurovascular protection through fine manipulation. [0003] Neurosurgery is characterized by deep location, complex neurovascular structure, difficult separation, and serious consequences after injury. The successful separation of the lesion from the tiny nerve or blood vessel is the key to ensure the success of the operation. The optimal separation mode is to hold the lesion with one instrument while the suction device...
