Problems solved by technology

This device needs to be made by the doctor himself, which is inconvenient to use
Moreover, when this device is inserted into the cranial cavity, because the front opening is too large, it is easy to damage the brain tissue, causing additional pain to the patient, and even serious accidents.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0020] Such as figure 1 and figure 2 As shown, in an implementation of the present invention, the endoscopic introduction device comprises an outer tube 1 with openings at both ends, and the front end of the outer tube 1 is conical; an inner tube 2 is also arranged in the outer tube 1, and the front end of the inner tube 2 is also It is conical, and the outer diameter of the inner tube 2 is compatible with the opening inner diameter of the front end of the outer tube 1, so that the inner tube 2 can pass through the opening at the front end of the outer tube 1, and the length of the inner tube 2 is greater than the length of the outer tube 1. When in use, put the outer tube 1 on ...

Abstract

The invention discloses an endoscope guiding device comprising an outer tube with openings at two ends, wherein the front end of the outer tube is shaped like a cone; an inner tube is arranged in the outer tube; and the front end of the outer tube is also shaped like the cone; the outer diameter of the inner tube is adapted to the inner diameter of the opening at the front end of the outer tube; and the length of the inner tube is greater than that of the outer tube. Through the endoscope guiding device disclosed by the invention, endoscopes or other surgical instruments can be conveniently guided into cranial cavity of a patient to carry out operations; large-area craniotomy is no longer needed to be carried out; the wound and the pain caused to the patient are small; the operation time is short; the recovery of the patient is rapid after the operation; and in addition, various operations such as tumour removing, hydrocephalus clearing and the like can be performed.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to an endoscopic introduction device used in neurosurgery. Background technique [0002] In neurosurgery, in order to reduce surgical trauma and minimize patient pain, endoscopy is required. During the operation, it is only necessary to open a small hole in the skull, and then use an endoscope introduction device to introduce the endoscope into the cranial cavity to perform the operation. The use of endoscope reduces the risk of surgery caused by large-scale craniotomy, and also reduces the pain of patients. In addition, during the treatment of cerebral edema and other diseases, it is also necessary to introduce a liquid suction device into the cranial cavity to absorb edema fluid. However, there is no special convenient and easy-to-use endoscope introduction device in the prior art. The current common practice is to select a syringe with a suitable size, remove the connector at the front...
