Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an adjustable and fixed brain endoscope sheath. Background Art

[0002] Brain endoscopy technology is a method used in the clinical treatment of cerebral hemorrhage. A hole of about 3 to 4 cm is opened in the patient's head. The current practice is to obtain the approximate location of the hematoma through CT scan, and then find a craniotomy point at this location, drill a bone window at the craniotomy point in the direction of the hematoma, and then insert a tubular sheath with a smooth outer surface as a channel (the channel is used to protect brain tissue from damage by instruments). The doctor inserts an endoscope (to observe the intracranial situation), a suction device (to absorb hematoma), and bipolar electrocoagulation (to stop bleeding) into the channel to perform the operation.

[0003] Currently, instruments including sheaths, endoscopes, aspirators, and bipolar electrocoagulation are all completely hand-held by doctors. There are currently no supporting devices, and the collaboration of more than two people is required. It is also very cumbersome, unstable, and inconvenient.

[0041] In order to facilitate understanding of the above technical solutions of the present invention, the above technical solutions of the present invention are described in detail below through specific usage methods.

[0042] The adjustable and fixed brain endoscope sheath of the present invention is applied to the technical field of medical devices, and is mainly composed of a fixing seat 1, an endoscope support 4 and a sheath 5.

[0043] The fixing seat 1 and the ball head locking cover 2 are provided with a pair of conical surfaces, and the first groove can play the role of opening and contracting. When the ball head locking cover 2 moves downward in a spiral, the two conical surfaces act on each other, thereby contracting the upper end of the fixing seat 1, and the top of the fixing seat 1 can be locked.

[0044] A locking flat thread 6-1 is provided inside the sheath locking ring 6, and the second groove 3-2 can play the role of opening and contracting. When rotating, it interacts with the flat thread 3-1 on the sheath fixing ball head 3, thereby contracting the upper end opening of the sheath fixing ball head 3, and can lock the top of the sheath fixing ball head 3.

[0045] The sheath 5 is inserted into the sheath fixing ball head 3. The sheath 5 is provided with a scale to mark the insertion depth. The operating frame 7 is fixed to the upper edge of the sheath 5. Two small ball heads 7-1 are installed on the operating frame 7, which can be rotated at will to provide a fulcrum for the suction device and bipolar electrocoagulation.

[0046] The endoscope ball head 8 is installed in the ball head groove in the endoscope fixing seat 4-2, and can also be rotated arbitrarily, which is convenient for use.

[0047] During specific use, the sheath is directly inserted into the patient's skull through the middle hole of the sheath fixing ball head. The sheath fixing ball head is connected to the ball head groove at the upper end of the fixing seat and can be rotated 360° at will. There are scale markings on the sheath. The depth of sheath insertion is set according to the data obtained from the preoperative CT scan, and then the sheath locking ring is rotated to relatively fix the sheath and the ball head. In this way, the doctor can hold the handle of the sheath to adjust the angle to accurately find the hematoma, and rotate the ball head locking cover to tighten the sheath fixing ball head, so that the sheath is completely fixed.

[0048] An operating frame is also fixed to the edge of the upper end of the sheath. The operating frame is equipped with two small ball heads to provide fulcrums for the suction device and double-click electrocoagulation, and can be rotated at will.

[0049] The endoscope is fixedly installed on the endoscope ball head, and the endoscope can be rotated freely in the endoscope fixing seat along with the endoscope ball head to adjust the angle and observe the hematoma.

[0050] In summary, with the aid of the above technical solution of the present invention, work efficiency is improved, and intracranial surgical operations only require one doctor to complete the operations of observing intracranial conditions, absorbing hematomas and stopping bleeding, and the instrument operation is simple and efficient.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
