Technical Field

The invention relates to an endoscope guider.

Background

At present, the endoscopic treatment of intracranial lesions is the latest and foremost neurosurgical technology. When the auxiliary endoscope enters into the cranium, the auxiliary endoscope guide device is needed to assist, so that the auxiliary endoscope guide device also has important function and significance for the research of the endoscope guide device.

Generally, an endoscope is used for assisting intracranial hematoma removal, a small bone flap is formed by drilling a hole at a position corresponding to a skull, then a puncture sleeve (with an inner core) slowly extends into an intracranial hematoma position through the skull flap, a core rod is pulled out after the puncture sleeve is positioned at a preset position, and then an endoscope and an aspirator are extended into a puncture tube to perform hematoma removal operation. Because the core rod of the puncture sleeve is a rod-shaped solid body, in the process that the puncture sleeve extends into the puncture sleeve, an operator cannot judge the accurate position of hematoma and only can indirectly observe and monitor the hematoma according to experience, and the effect is unsatisfactory.

Accordingly, there is a need to develop a new endoscope introducer that can solve the above problems.

Disclosure of Invention

The invention aims to provide an endoscope guide sheath which is small in wound and accurate in positioning.

The technical solution adopted for achieving the object of the present invention is that an endoscope introducer comprises a sleeve and a core rod, wherein the sleeve and the core rod are made of transparent materials.

The sleeve comprises a cylinder body and a closing-in, the cylinder body is a hollow cylinder, and two ends of the cylinder are both open. One end of the barrel is connected with a closing-in which is funnel-shaped. The maximum diameter of the binding off is equal to the outer diameter of the cylinder and is marked as a, the minimum diameter of the binding off is marked as b, and a > b > 0.

The sleeve is sleeved on the core rod, and the core rod comprises a rod body and a gradual change end. The bar body is a cylinder with a hollow inner part, and two ends of the cylinder are both open. The two ends of the rod body are respectively marked as the front end and the rear end, the front end of the rod body is connected with a gradual change end, and the gradual change end is in a closed shape. The diameter of the gradual change end along the direction far away from the rod body is gradually reduced.

The maximum diameter of the gradual change end is equal to the outer diameter of the rod and is marked as c, a > c > b > 0.

Furthermore, the outer wall of the gradual change end is tightly abutted to the closing-in, and the part of the gradual change end with the diameter smaller than b extends out of the closing-in. The rear end of the core rod extends out of the cylinder body.

Furthermore, the inner part of the core rod is used for inserting the endoscope tube of the endoscope.

Further, the surface of the gradual change end is smooth.

Further, the sleeve and the core rod are both made of transparent glass.

The technical result of the invention is undoubtedly that with the endoscope guide of the invention, the endoscope and the puncture outfit can be entered together in the initial stage. The user can puncture under the vision, can the accurate scope guide of judging whether reach the hematoma position, and the degree of depth of accurate judgement hematoma has improved the success rate that operation was clear away to intracranial hematoma. Meanwhile, the front end of the inner core is in a smooth and gradually reduced shape, so that the trauma of brain tissues and blood vessels caused by puncture operation in the operation is reduced. The invention is a full-glass high-temperature resistant structure, has low manufacturing cost, is convenient to clean, can be repeatedly sterilized and is convenient for the primary hospitals to carry out the neurosurgical endoscope minimally invasive surgery.
