Description
Technical Field
The utility model relates to the technical field of medical operation equipment, in particular to a medical craniocerebral operation channel closing device.
Background
The basic process of craniocerebral operation includes three stages of craniotomy, operation in brain and craniotomy. After the surgical field is disinfected and spread with a sterile towel, entering a craniotomy procedure: the scalp is cut open, the flap opened, and then the skull flap is cut open and freed with a tool, and the dura mater is cut open. Then carrying out operation in brain, and entering into a craniotomy procedure after the operation is finished: the dura mater is sutured, the skull is fixed by a nail plate, and the scalp incision is sutured. Conventional craniotomy procedures take at least about 1-2 hours to complete (depending on the skill of the surgeon).
During the operation of brain surgery, deep brain hemorrhage, brain tissue displacement at the excision site, etc. are often encountered, which results in the operator deciding that the surgery needs to be temporarily suspended for the related examination, such as intra-operative CT scan, intra-operative magnetic resonance scan, or transfer to other surgery rooms with related fixtures (e.g. DSA surgery room, laser surgery room, etc.), and then continue the surgery treatment. The craniocerebral closure is needed to be performed temporarily, the surgical access is needed to be closed aseptically and the surgical area is needed to be wrapped and covered aseptically, and the craniocerebral closure characteristic is recovered, so as to prevent the infection and the like caused by the excessive loss of cerebrospinal fluid, the displacement and hernia of brain tissue, hemorrhage or surgical field pollution.
Since most of these situations occur urgently and require the surgical treatment to be continued thereafter. This requires that the craniocerebral closure be completed within minutes, which conventional craniotomy procedures cannot.
The method for sealing the temporary craniocerebral operation channel at the present stage comprises the steps of covering the surface of the brain with operation brain cotton, filling the positions of the skull and the scalp of the operation channel with a plurality of layers of gauze, reversely buckling the aseptic plastic basin outside the channel to play a role of rigid support, fixing and covering a plurality of aseptic layers with adhesive tapes to prevent infection, wrapping the outermost layer with an aseptic plastic bag, completing all sealing operations, performing other inspection and other work. And after the operation is finished, removing layer by layer according to the reverse process, and continuing the operation.
However, the above-mentioned temporary craniocerebral operation channel closure method has the following problems:
1. the above process is still relatively complex, taking about 15-20 minutes; the time for removing the aseptic protection is about 10 minutes;
2. during the operation, brain cotton, gauze and the like have obvious water absorption effect, so that a large amount of cerebrospinal fluid is continuously lost in the subsequent process, brain tissues can be gradually deformed and dehydrated, and flexible materials such as the brain cotton, the gauze and the like can enter into the cranium to press the brain tissues under the action of gravity or pressure; meanwhile, the air which flows back to the brain tissue has certain stimulation and damage;
3. when the head position is changed during the CT operation and the magnetic resonance scanning or moving during the operation, the position of the operation channel is changed, the brain tissue and the cerebrospinal fluid are shifted outwards under the action of gravity, and the brain tissue is extruded from the operation channel, extruded and damaged, bleedings and the like.
4. Cerebrospinal fluid can also be greatly lost, so that the whole brain tissue cannot float, and the risks of nerve dysfunction, bleeding and the like caused by deep brain tissue vascular traction injury, bleeding, brain tissue collapse, contusion and the like can be caused;
5. the air entering the intracranial space stimulates and damages brain tissues, and generates serious interference on image scanning, so that image deformation, artifacts, interference and the like are caused, and the scanning result is influenced;
6. due to the lack of an effective fixing means, the sterile plastic basin is difficult to stably fix in a reverse buckling mode, and when an operation channel with a large area is used, the sterile plastic basin can collapse into the cranium, so that brain tissues are accidentally damaged, and danger is caused.
