Problems solved by technology

[0004] During the clinical operation of minimally invasive lumbar surgery, the positioning of the Quandrant minimally invasive channel tube when it is connected to the spine is relatively difficult. At present, it is mainly determined by the experience of the operator. Relying on the experience of the operator, there are no medical devices that can assist in positioning, which increases the difficulty of the operation process and prolongs the operation time

Embodiment 1

[0040] Such as figure 1 and figure 2 As shown, this embodiment provides an auxiliary device for minimally invasive lumbar surgery, including a cylinder 1, on which a plurality of head ends 1-1 and tail ends 1-1 through the cylinder 1 are processed along the axial direction. The channel 2 of 2, the channel 2 is symmetrically arranged with the central axis of the cylinder 1 as the center of symmetry;

[0041] The side wall of the cylinder 1 close to the tail end 1-2 is fixedly provided with a rotating pointer disk 3, the rotating pointer disk 3 is installed in the rotating scale seat 4, the rotating pointer disk 3 is provided with a pointer 5, and the rotating scale seat 4 A rotation angle scale 6 is arranged on the top, and the rotation angle of the cylinder 1 can be indicated by rotating the pointer disk 3 and the rotation scale seat 4 when the cylinder 1 rotates;

[0042] The rotating scale base 4 is installed on the first universal joint 7-3 of the adjustable mounting bas...

Embodiment 2

[0051] Comply with the above technical solutions, such as image 3 and Figure 4 As shown, this embodiment provides an auxiliary tool for minimally invasive surgery of the lumbar spine, including a cylinder 1, on which a plurality of head ends 1-1 and tail ends 1-1 through the cylinder 1 are processed along the axial direction. The channel 2 of 2, the channel 2 is symmetrically arranged with the central axis of the cylinder 1 as the center of symmetry;

[0052] A holding mechanism 9 is provided on the side wall of the cylinder 1 near the tail end 1-2.

[0053] The head end 1-1 of the cylinder 1 is a spherical arc surface, so that the end of the cylinder 1 can have good contact with the spine at all angles.

[0054] The inner diameter of the channel 2 is 1.6 mm, and the distance between the central axes of two adjacent channels 2 is at least 2 mm. The inner diameter of channel 2 should meet the requirements of the Quandrant minimally invasive channel tube.

[0055] The cyli...

Abstract

The invention provides an auxiliary tool and device for a minimal invasive lumbar surgery. The auxiliary tool comprises a cylinder, wherein a plurality of channels running through the head end and the tail end of the cylinder are formed in the cylinder in the axial direction; the channels are symmetrically arranged by taking the central axis of the cylinder as the symcenter; an adjustable mounting seat or a holding mechanism is mounted on the side wall, close to the tail end, of the cylinder. The auxiliary tool and device are used in the minimal invasive lumbar surgery of a Quandrant minimally invasive channel of a lumbar patient and can assist a surgical operator in well connecting a Quandrant minimally invasive channel tube to a site, required to be connected, on a spline, and auxiliary positioning of the Quandrant minimally invasive channel tube can be performed, so that the positioning frequency is reduced, the positioning success rate and accuracy are improved, the surgical operation difficulty is reduced, and time is saved for the surgical operator.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to oral medical teaching and training equipment, in particular to an auxiliary tool and device for minimally invasive lumbar surgery. Background technique [0002] In the past, open lumbar spine surgery required the lumbar erector spinae to be stripped to both sides and forcefully pulled apart, which resulted in large trauma, heavy bleeding, slow recovery, and prone to postoperative soft tissue adhesions, resulting in repeated low back pain and even failed lumbar surgery syndrome. . Lumbar minimally invasive surgery under the Quandrant minimally invasive channel for lumbar patients uses the most advanced expandable channel minimally invasive surgical system in spinal surgery. It only needs an incision of about 4 cm in the middle of the waist, and can be expanded through the most advanced (MASRQuadrant) at present. The minimally invasive channel performs minimally invasive intervertebra...
