Description

Chronic subdural hematoma flushing device

Technical Field

The disclosure relates to the field of medical equipment, in particular to a chronic subdural hematoma flushing device.

Background

Chronic subdural hematomas are a common neurosurgical condition. Especially, the traditional Chinese medicine is easy to cause hematoma and large in volume in old patients, and even has cerebral hernia. Due to the presence of multiple hemorrhages, the separation of hematomas, including different periods of hemorrhage, the simultaneous presence of subacute and chronic hematomas, most patients require surgical treatment. The drilling flushing external drainage technique for chronic hematoma is the most commonly used method for treating chronic subdural hematoma, has the characteristics of simplicity, micro-wound, high efficiency and the like, and can be used for gradually flushing and draining the hematoma by using a single-hole or double-hole drilling indwelling external drainage tube (a direct incision single-hole drilling craniotomy drainage tube is applied in a Tiantan hospital) in an operation so as to reset the compressed brain tissue. Because many old people have brain atrophy conditions at the same time, the hematoma is difficult to be completely drained only by the pressure of brain tissue refolding, and therefore, the problem of relapse caused by hematoma residue after operation is easy to occur. Here, the key problem is that the internal separation of hematoma is dredged as far as possible in the middle of the operation, so that the hematoma is flushed and drained as clean and thorough as possible, and even if brain tissues cannot be fully retensioned and a small amount of subdural effusion remains, the hypertonic subdural old hematoma cannot be left to cause relapse, and the operation is of great importance for preventing the relapse of hematoma.

At present, no special flushing pipe is available in the operation, most of operations in the Tiantan hospital use the Meidunli ventricular drainage tube (26020, the inner diameter is 2.6mm, 4.9mm or 27703, the inner diameter is 1.98mm, and the outer diameter is 3.14mm), the operation is kept in a hematoma cavity for flushing and drainage, the 26020 is thick and hard, the operation is not easy to be blocked by small blood clots, and the operation is suitable for the postoperative retention and drainage; the texture is hard, and hematoma separation is easy to get through during flushing; but easily penetrate the haematoma wall and into the brain tissue. 27303 is soft and thin, and is not easy to damage brain tissue by piercing wall layer when washing the periphery, but the whole tube is soft and has poor hand feeling; the head end is soft and blunt, so the utility model is not suitable for being used as a tool for getting through the separation of hematoma cavities; in addition, the tube diameter is thin, so the tube is easily blocked by small blood clots, and the postoperative indwelling drainage effect is poor.

The invention relates to a chronic hematoma operation, which is a combined body that can be used for washing and draining, namely a combined tube with two functions. We advocate that the two parts cannot be designed together, so that the efficacy of the two functions is reduced, and the two parts should be designed separately, because the drainage tubes in the current medical treatment are of various types, and it is easy to find the drainage tube suitable for being kept after the operation according to the conditions in the operation, such as the drainage tube of the ventricle of the Meidunli 26020 which is a mature product at present, and the purpose is to realize smooth drainage. In summary, we focus on the first step flush tube design.

Chronic hematoma is mostly placed in the oval occupy-place of brain surface class, whole hematoma diameter is mostly 15-25cm, thickness is 1-3cm inequality, the outside is than thicker visceral layer and parietal, be thick petroleum-like liquid in it, wherein mix the clot of little cubic unliquefied, because there is arachnoid adhesion or vein bridging between brain surface and the dura mater, arachnoid thickness is different, in addition can have the hemorrhage of different periods, there is difference along with the liquefaction degree in time, so form hematoma easily and separate, different density also can be seen on the CT, also can confirm in the art. In the operation, because the scalp has a certain thickness, the skull drilling hole is mostly expanded into a single hole with the diameter of 1-1.5cm, and the drilling hole is positioned in the center of hematoma and is slightly deviated from the occipital part (thereby being beneficial to drainage in the postoperative lying position). Afterwards, put into the wash pipe, go deep into hematoma and continuously wash all around, the head end that has certain hardness can be opened the partition, is unlikely to break through again simultaneously that hematoma dirty layer inserts in the middle of the brain tissue, and the device needs to satisfy the several:

1. because the hematoma layer is much thicker than the separation in the hematoma cavity, the design of the head end of the device has certain hardness, the hardness can puncture the separation in the hematoma cavity, and the hardness cannot puncture the hematoma layer.

2. The irrigation tube needs to have a certain degree of curvature, and can exert force all around but not directly downwards.

3. The operator needs to have certain hand feeling when holding the washing tube for operation, and can sense whether the peripheral edge position, namely the hematoma visceral layer, has been reached through the washing tube when exploring four weeks. Stopping the force when the force is reached.
