Background technique

With the trend of population aging becoming more and more obvious, the number of people taking anticoagulant drugs and blood-activating health care products is increasing day by day. Chronic subdural hematoma has become a common neurosurgical disease, especially in elderly patients with a history of craniocerebral trauma. More common in. Most of these hematomas are large in size and have a mass effect, and even brain herniation is life-threatening and requires surgical intervention. At present, burr hole irrigation and drainage for chronic subdural hematoma is the most common and effective method for the treatment of chronic subdural hematoma.

The operation process is not complicated. Select the area with the most obvious hematoma, make a straight incision about 3 cm in length, open the skin, muscle and periosteum, use an electric drill or a hand drill to drill a bone hole with a diameter of 1-1.5 cm, and place a drainage Tube. Through flushing, the hematoma is gradually drained by the drainage tube until the flushing fluid is clear, so that the compressed brain tissue can be restored and reset, and the herniation of the brain can be relieved. During the operation, the insertion of the drainage tube through the bone hole requires the surgeon's feel and experience to place the tube. However, the whole operation cannot be performed under direct vision. The process of inserting the drainage tube is blind. In the area other than the bone hole, it is completely dependent on the operator's hand feeling. In addition, the soft drainage tube may be blocked from the rear of the separation if there is a separation. The removal and drainage of the hematoma may also lead to the wrong direction of the drainage tube, resulting in a large residual hematoma after the operation, resulting in a high recurrence rate of the hematoma.

In view of the above problems, the utility model proposes an auxiliary device for placing a tube in the drilling and drainage of chronic subdural hematoma.

In the prior art, the traditional treatment of chronic subdural hematoma is surgical treatment, including drilling and drainage. Although the drainage operation can quickly relieve the patient's symptoms, there is still a recurrence rate of 5%-30%. Drill hole drainage is currently recognized as the preferred surgical method. It is simple to operate, less traumatic, and can even be performed under local anesthesia. However, the whole operation cannot be performed under direct vision, and the process of placing the drainage tube is blind. In the area other than the bone hole, it depends entirely on the operator's touch, and in the case of the separation, it may block the removal and drainage of the hematoma behind the separation by the soft drainage tube, which may lead to the direction of the drainage tube and a large residual hematoma, which may lead to surgery. The recurrence rate of hematoma is higher. In view of the above problems, the present application proposes an auxiliary device for catheter placement in chronic subdural hematoma drilling and drainage, including a hand-held part and a partition part. In the burr hole drainage operation of chronic subdural hematoma, the partition part is first inserted into the hematoma cavity through the bone hole, so that the partition in the hematoma cavity can be opened with the partition part. Then, the drainage tube is inserted through the tube insertion hole of the handle part. The drainage tube passes through the tube hole and extends along the tube slot until it reaches the other end of the partition, that is, reaches the hematoma cavity. The partition is used to control the running direction of the drainage tube. The utility model is used as an auxiliary device for inserting tubes in the drilling and drainage of chronic subdural hematoma, and the drainage tube can be inserted into the hematoma cavity without depending on the operator's hand feeling or operation experience. And the partition part can open the partition in the hematoma cavity, preventing the hematoma partition from blocking the removal and drainage of the hematoma behind the partition by the soft drainage tube.

Various non-limiting implementations of the present application will be described in detail below with reference to the accompanying drawings.

The tube insertion slot 21 designed in this way can not only guide the drainage tube 4 into the cranium, but also facilitate cleaning and disinfection of the tube insertion slot 21 after use, so as to avoid residual blood and human tissue fluid.

In one embodiment, the handle 1 includes a first handle 13 and a second handle 14, the first handle 13 and the second handle 14 are detachably connected, and the first handle The part 13 is provided with a first arc groove, the second handle part 14 is provided with a second arc groove, and the first arc groove and the second arc groove are connected to form the tube insertion hole 11 . The handpiece 1 is designed in this way. On the one hand, after the drilling and drainage of chronic subdural hematoma, the tube hole 11 in the handpiece 1 can be cleaned and disinfected to ensure that the next use meets the requirements of medical hygiene; on the other hand, After the guiding and draining tube 4 is placed into the intracranial, it is convenient to disassemble the first hand-held part 13 and the second hand-held part 14 under the condition of fixing the draining tube 4, and take out the partition part 2 from the intracranial . In order to facilitate cleaning and disinfection of the tube insertion hole 11, the first arc groove and the second arc groove are designed.

In order to separate the first handle part 13 from the second handle part 14, the partition part 2 is connected to the first handle part 13, and the direction part 3 is connected to the second handle part 14. connected. The first handle part 13 and the second handle part 14 can be separated by pinching the direction part 3 and the partition part 2 and pulling them in different directions.

In one embodiment, the diameter of the tube insertion hole 11 is 2.8-3.2 mm. The diameter of the tube insertion hole 11 is set to meet the specifications of the medical drainage tube 4 , which is convenient for inserting the drainage tube 4 into the tube insertion hole 11 . The diameter of the drainage tube 4 is also 2.8-3.2 mm. When the diameter of the drainage tube 4 is within the stated value, it is convenient to drain the hematoma. If the diameter of the drainage tube 4 is too small, it is difficult to drain, and if the diameter of the drainage tube 4 is too large, it is easier to damage the intracranial tissue when it is inserted into the cranium.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention and not to limit them.
