Description

Duck claw type aspirator for endoscope

Technical Field

The utility model relates to the technical field of attractors, in particular to a duck claw type attractor for a cavity mirror.

Background

The aspirator is an important instrument in operation, almost covers all operation types, has the important functions of keeping the operation field clean, stripping soft tissues and exposing the operation field in operation, however, the continuous development of operation equipment brings about continuous change of operation modes and operation skills, new requirements are put on the operation instrument, and the application of the traditional aspirator in thoracoscopic operation is greatly hindered. The thoracoscopic operation mainly comprises heavy level 4 operations such as radical lung cancer operation, radical esophagus operation and the like, has high operation difficulty and high risk, and particularly has higher risk of massive hemorrhage in the operation, thus having higher requirements on the aspirator. In the operation, the bleeding usually needs to be quickly stopped by suturing, and the damaged blood vessel is a thick functional blood vessel due to thoracoscopic operation, so that the bleeding amount is fierce, the time is urgent, and the current thoracoscopic aspirator can not meet the requirements of thoracoscopic operation. The convenience and effectiveness of aspirator use is not fully demonstrated in thoracoscopic procedures.

The existing aspirator has the following defects:

patent document CN214966315U discloses a thoracoscopic surgery aspirator, which comprises an aspirator body, wherein the aspirator body is in a circular tube shape, one end of the aspirator body is provided with a bending part, the inside of the bending part is hollow and is communicated with the inside of the aspirator body, the end part of the bending part is provided with a movable clamp flap and a fixed clamp flap which are mutually matched, one end of the movable clamp flap is hinged with the bending part, the rotating direction of the movable clamp flap is vertical to the sagittal plane of the aspirator body, and the inside of the fixed clamp flap is hollow and is communicated with the inside of the aspirator body; the other end of the aspirator body is sequentially provided with a negative pressure interface and a holding part from the end head to the direction of the bending part; debakey teeth are arranged on the surfaces of the movable clamp petals and the fixed clamp petals, which are mutually matched, and suction holes are formed in the ends of the fixed clamp petals. The utility model can avoid frequent replacement of instruments in thoracoscopic surgery and improve the surgery efficiency; simultaneously, medical staff can be enabled to carry out finer operation, and operation risks are reduced.

However, the aspirator of above-mentioned publication mainly solves the problem that improves operation efficiency, but still there is the appearance fixed, the radian of aspirator, length is fixed, and can not carry out individualized adjustment according to operation type, so in the great body cavity of depth such as thorax, there is certain field of vision blind area of use, operation in the blind area, aspirator can not be related, and traditional endoscope aspirator, aspirator head is the metal material, comparatively smooth, after contacting with thorax tissue such as lung, the unstable circumstances of fixation often appears, slippage etc. in hemostatic process, the appearance of this condition means more, more bleeding of inletting, the roughening surface treatment of aspirator head that partial aspirator carried out, but increase the risk of damaging the tissue when reinforcing fixed stability, often, lung tissue damage appears in the peeling process, lead to leaking blood, need to carry out the injury repair, the aspirator of the chamber of using now, aspirator head form is various, but all be single aspirator, the side opening, the in-process that blood vessel is ruptured and is sewed up, the vascular risk of injury, the vascular risk is great, the vascular obstruction is great, the vascular obstruction is difficult to open under the circumstances, the operation of the severe injury is difficult to the patient, the problem is frequently changed to the vascular repair, the injury is difficult in the vascular repair.

In view of the above, it is necessary to develop a duck claw type aspirator for a endoscope, which can further improve the use effect of the aspirator.
