Stent type UBE operation channel establishing instrument

Abstract

A single support type UBE operation channel establishing instrument comprises a supporting structure fixedly arranged on an operation bed or an exercise platform, and the supporting structure comprises two parallel arrangement rods; the supporting structure further comprises a plurality of supporting legs for supporting the setting rod; a channel building structure is arranged on each setting rod; the channel establishing structures are integrally connected through a connecting structure, the two channel establishing structures are each provided with a cannula guiding structure, the two cannula guiding structures can rotate on the channel establishing structures to adjust the angle, and the two cannula guiding structures guide a cannula to establish an operation channel on the same channel establishing plane. The channel building structure comprises a moving section combined with the setting rod and a setting section extending out of the moving section, and a sleeve guide structure is arranged on the setting section; and a rotating dial and a rotating pointer which are used for reading a rotating angle are arranged. Through the arrangement, the purposes that the angle of the sleeve guide structure is adjusted according to needs, and entering is conducted on one plane can be well achieved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to an instrument for establishing a single-stent type UBE operation channel. Background technique [0002] UBE surgery is a unilateral dual-channel endoscopic technique, which is a kind of vertebral body surgery. Percutaneous observation and operation channels are respectively established through two small incisions on one side of the posterior approach, and endoscopes are placed in the observation channels to monitor the surgical field of view. Mirror instruments, and operating tools are placed in the operating channel for surgical operations inside and outside the spinal canal. Because of its good surgical field of view, this kind of surgery is currently being promoted in clinical practice. [0003] However, before the operation, cannulas of different calibers need to be obliquely entered at the two incisions and converged under the skin to establish an ef...

AI Technical Summary

Problems solved by technology

[0003] However, before the operation, cannulas of different calibers need to be obliquely entered at the two incisions and converged under the skin to establish an effective surgical operation space. , and the establishment of one channel and one channel is often required during operation, so that the entry angles of the two cannulae are prone to deflection when they are established, which leads to the staggered entry planes of the two channels, and finally leads to the inability to establish intercommunication. The channel of space, once this phenomenon occurs, it is very difficult to adjust and adjust

[0004] In addition, at present, clinicians mostly use specific surgical exercises to complete the initial learning of channel establishment. The learning curve is long and the risk of surgery is high. If there are devices that can assist doctors in non-operative conditions, look for channels to establish angles during surgery. Devices will greatly reduce the learning curve for doctors

[0005] Therefore prior art lacks a kind of channel establishment instrument that can be used in operation, can assist doctor to exercise again under non-operative state
