Description

A suction-free strip

technical field

The utility model relates to the technical field of medical equipment, in particular to a suction device for a non-passing strip.

Background technique

The suction device is mainly used as the terminal device connected to the suction tube in the operation to contact the suctioned object. The suction device can have various shapes according to the function, such as round, umbrella, and oval. In order to prevent the suction tube from being blocked by the suctioned object, Usually the suction tube is equipped with a corresponding cleaning rod to clear the blocked suction tube.

Regarding the aspirator in the prior art, clinicians have the following defects and deficiencies during use:

First of all, once the traditional suction device is blocked, it is necessary to insert a cleaning rod through the suction port of the suction tube, or remove the suction device from the suction tube and use a cleaning rod to clear it. This operation is time-consuming, and repeated operations have a certain impact on the operation progress. influences.

Secondly, with the development of contemporary surgery, the concept of shortening the operation time under the premise of ensuring the operation standard has gradually gained the consensus of surgeons. There is no doubt that the reduction of operation time will reduce the operation risk, but many non-medical factors often lead to the reduction of operation time. Extended, the suction device often faces the problem of blockage of the attracted large soft tissue. The simple mechanical pull-in unblocking method of the traditional suction device often cannot effectively re-pass the blocked suction device, resulting in a decrease in the suction force of the suction device. It will inevitably lead to prolonged operation time.

Chinese patent document CN201710597897.4, application date 20170720, the patent name is: a new flushable intraoperative aspirator cleaning device, which discloses a multifunctional aspirator head for minimally invasive neurosurgery, including the aspirator head connection Suction pipe joint, water injection joint and electrocoagulation line joint, suction head body, suction head end and successively through the suction head to connect the suction pipe joint, water injection joint and electrocoagulation line joint, suction head body, suction head The suction head at the end is connected to the suction pipe joint and fixedly installed above the water injection joint and the electrocoagulation line joint. One end of the suction head body is connected to the end of the suction head, and the other end of the suction head body is fixedly connected to the water injection joint. and below the electrocoagulation line joint; the water injection joint, the electrocoagulation line joint, and the interior of the head body of the suction device are provided with a water channel.

The aspirator of the above-mentioned patent document is minimally invasive, easy to operate, has multiple functions such as suction, stripping, dripping, measurement, and electrocoagulation, and is not easy to be blocked, easy to clean, and can greatly reduce the complications of postoperative nerve injury, so that the suction can Unimpeded, suitable for all kinds of neurosurgical microsurgery. However, there is no corresponding disclosure about a technical solution that can prevent the mouth of the suction device from being blocked, reduce the operation time, and reduce the probability of being blocked and need to be dredged.

In summary, there is a need for a strip-free aspirator that can prevent the mouth of the aspirator from clogging, reduce operation time, and reduce the probability of needing to be dredged with a strip after being blocked. However, there is no report about this strip-free suction device. .
