Problems solved by technology

[0004] The purpose of the present invention is to address the deficiencies in the prior art, to provide a variable-angle V-shaped dual-channel working sheath for spinal endoscopic surgery, to realize the spatial direction position locking of the endoscope and medical instruments, and to avoid The middle endoscope cannot observe the occurrence of surgical instruments, and realizes synchronous operation with one hand, which is convenient for reducing damage to tissues or nerves when the whole device enters human tissues when the endoscope working channel is opened

Embodiment 1

[0031] Such as Figure 1a to Figure 1c as shown,

[0032] A variable-angle V-shaped double-channel working sheath for spinal endoscopic surgery, including a handle main body of the working sheath, wherein a snap ring is arranged on the handle main body of the working sheath, and the snap ring is used to connect the detachable connection handle 1 or The robot or mechanical arm, the detachable connection handle on the clasp, the robot or the mechanical arm, is confirmed by the operation overview before operation, and can also be freely replaced among the three during the operation, all in order to improve the surgical performance. The stability of the overall device, thereby reducing the pressure and fatigue of the doctor's left-handed instrument, the present invention is preferably a detachable connection handle; the snap ring is specifically arranged between the endoscope locking depth regulator 2 and the working sheath channel-3 position, and finally nested and connected wit...

Embodiment 2

[0039] Such as Figure 1a to Figure 3 As shown, the working sheath channel 1 of the working sheath is designed with a water inlet channel 9, a water outlet channel 10 and an endoscope channel 7, and an instrument channel 8 is designed in the working sheath channel 2 4, and the instrument channel 8 is used for installing surgical instruments 13. When removing the soft tissue, the endoscope channel 7 is equipped with an endoscope 11 for accurate and quick resection of the endplate cartilage under direct vision.

[0040]During the operation, if it is necessary to adjust the size of the V-shaped angle between the two channels, you only need to open the elastic stretching structure 6 with one hand, and the V-shaped angle will gradually increase. At this time, when the V-shaped angle in the endoscope 11 When the operation profile reaches the best imaging, the elastic stretching structure 6 can be closed, and with the cooperation of the elastic shaft 5, the V-shaped corner can be loc...

Abstract

The invention relates to a variable-angle V-shaped double-channel working sheath for spine endoscopic surgery. The variable-angle V-shaped double-channel working sheath comprises a working sheath grab handle body, wherein a clamping ring is arranged on the working sheath grab handle body and used for being connected with a detachable connecting grab handle or a robot or a mechanical arm, and the working sheath grab handle body is provided with a working sheath channel I and a working sheath channel II which are independent of each other; and the bottoms of the working sheath channel I and the working sheath channel II are connected side by side through an elastic rotating shaft, the tops of the working sheath channel I and the working sheath channel II are jointly connected to an elastic opening structure, and an endoscope locking depth adjuster is further embedded in the upper end of the working sheath channel I. The angles of the two channels of the working sheath can be adjusted, the depth of the connected endoscope can be adjusted in real time, windows are formed in the tail ends of the instrument channels, the flexibility of instrument operation is improved, the endoscope is prevented from being damaged, the injury risk generated by surgical instruments is reduced, and the situation that the surgical instruments cannot be observed by the endoscope in the surgical process is avoided.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to a variable-angle V-shaped double-channel working sheath for spinal endoscopic surgery. Background technique [0002] In the past ten years, spinal endoscopy technology has developed rapidly. With the continuous improvement of doctors' requirements for spinal endoscopy technology, more and more doctors hope to expand the application range of spinal endoscopy Endoscopic technology is further applied to complex surgical operations such as severe spinal stenosis decompression and spinal fusion. The single-axis single-channel coaxial endoscopic system widely used before has shortcomings such as inflexibility, low processing efficiency, and easy damage to instruments. has been exposed. [0003] Therefore, unilateral dual-channel spinal endoscopy (UBE / BESS) has attracted extensive attention from spinal surgeons. Due to its relatively gentle learning curve, large field of view under...
