Technical Field
The utility model relates to the field of medical equipment, in particular to a neural endoscope channel with an adjustable angle.
Background
Neural scope or surgical instruments are through the device that neural scope passageway reached "pathological change structure" through the brain tissue, carry out the encephalic hematoma and clear away the art, are the indispensable surgical equipment of neural scope operation, and the neural scope passageway among the prior art can't be according to the suitable angle of adjustment in "pathological change structure" place.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an angle-adjustable neuroendoscope channel.
The novel point of the utility model is that the spherical steering piece can rotate in a cavity formed by the base and the limiting sleeve, the spherical steering piece rotates to drive the channel tube to rotate together, and finally the spherical steering piece is locked by the downward rotation of the limiting sleeve, so that the adjustment of the channel angle of the whole neuroendoscope is realized.
In order to realize the purpose of the utility model, the technical proposal of the utility model is as follows:
the utility model provides an angle-adjustable's neural scope passageway, includes the base, and the base outer lane is equipped with a plurality of connecting holes, is equipped with the base through-hole of arranging along base direction of height on the base, and the base top is equipped with spherical indent, and the base upper portion outside is equipped with the external screw thread, the base top spin has connect the equal open-ended stop collar in top and bottom, is equipped with the sphere between stop collar and the base and turns to the piece, be equipped with on the sphere and turn to a through-hole, turn to a through-hole bottom and be connected with the passageway pipe that stretches out the base through-hole, passageway pipe diameter is less than base through-hole diameter, turn to a through-hole and passageway pipe formation inner core and insert the passageway.
Further, the passage tube and the spherical steering member are integrally formed.
Further, the diameter of the inner core insertion channel is gradually reduced from top to bottom. The insertion is facilitated.
Furthermore, the base is of a split structure and comprises a base inner ring body and a base outer ring body, the connecting hole is formed in the base outer ring body, and the base inner ring body and the base outer ring body are connected in a screwed mode through threads. A plurality of outer ring bodies of the base with different outer diameters can be arranged, and the size of the outer ring body of the base can be adjusted according to the size of the skull flap.
Furthermore, a rubber layer is arranged at the position limiting on the top of the limiting sleeve. And the spherical steering piece is limited in skid resistance.
Further, the wall body of the channel pipe is made of transparent materials. The condition of the brain tissue outside the channel tube is convenient to observe.
Furthermore, scales are arranged on the wall body of the channel pipe. It is convenient to know the insertion depth.
The utility model has the beneficial effects that:
1. the spherical steering piece can rotate in a cavity formed by the base and the limiting sleeve, the channel tube is driven to rotate by the rotation of the spherical steering piece, and finally the spherical steering piece is locked by the downward rotation of the limiting sleeve, so that the angle of the channel of the whole neuroendoscope is adjusted.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Example 1: as shown in figure 1, but angle regulation's neural scope passageway, including base 1, 1 outer lane of base is equipped with a plurality of connecting holes 2, is equipped with the base through-hole 3 of arranging along 1 direction of height of base on the base 1, and 1 top of base is equipped with spherical indent 4, and 1 upper portion outside of base is equipped with the external screw thread, and 1 top and the equal open-ended stop collar 5 in bottom have been connect on the base, and 5 top spacing departments in stop collar are equipped with the rubber layer. Be equipped with the sphere between stop collar 5 and the base 1 and turn to piece 6, be equipped with on the sphere and turn to a through-hole 7 on 6, turn to 7 bottoms of a through-hole and be connected with the passageway pipe 8 that stretches out base through- hole 3, 8 wall bodies of passageway pipe are transparent material, are equipped with the scale on the 8 wall bodies of passageway pipe. The diameter of the channel pipe 8 is smaller than that of the base through hole 3, the channel pipe 8 and the spherical steering piece 6 are integrally formed, the steering piece through hole 7 and the channel pipe 8 form an inner core insertion channel 9, and the diameter of the inner core insertion channel 9 is gradually reduced from top to bottom.
Example 2: referring to embodiment 1, as shown in fig. 2, the base 1 is a split structure, and includes a base inner ring body 1.1 and a base outer ring body 1.2, the connection hole 2 is located on the base outer ring body 1.2, and the base inner ring body 1.1 and the base outer ring body 1.2 are screwed together by a screw thread.
When the neural endoscope channel angle adjusting device works, a screw is screwed into the connecting hole to fix the base 1 on a skull, the spherical steering piece 6 can rotate in a cavity formed by the base 1 and the limiting sleeve 5, the spherical steering piece 6 rotates to drive the channel tube 8 to rotate together, and finally the spherical steering piece 6 is locked by downward rotation of the limiting sleeve 5, so that the adjustment of the whole neural endoscope channel angle is realized.
The described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
