Problems solved by technology

[0003] To sum up, the current UBE surgical treatment process has the following technical problems: 1) When establishing the channel, the medical staff used a 2ml syringe to trim the lower end of the syringe into an inclined plane. 2) The diameter and length of the channel established by trimming the existing needle barrel are fixed; when the patient is obese and the back tissue is thick, the length of the channel established by the trimmed needle barrel cannot reach the target position, and the channel diameter established by the trimmed syringe cannot be revealed Target position; for thinner patients, the needle cylinder is left outside the body after trimming for too long, which will affect the operation; it cannot meet the channel establishment of patients with different body shapes, 3) the channel established by the trimmed syringe cannot be fixed on the patient, which will affect the operation under the channel The stability of the channel is constantly adjusted during the operation process, which makes the operation process cumbersome or even impossible to continue the operation

Embodiment 1

[0046] like Figure 1-11 , 17 and 18 show

[0047] An adjustable channel for unilateral double-channel endoscopic nucleus pulposus in the present invention comprises a side panel (3), an adjustment block (2) and a vertical frame (1). hole, the middle of the side wings is provided with a plurality of adjustment blocks (2), the adjustment blocks (2) are arranged in a circular array around the center of the through hole of the side wing plate (3), and the adjustment blocks (2) are slidably connected to each other. The two side faces of the adjustment block (2) sliding mutually form an acute angle, and the lower side of the adjustment block (2) is provided with a corresponding vertical frame (1), and the shape of the vertical frame (1) is consistent with that of the adjustment block (2). A length adjustment assembly is arranged between the vertical frame (1) and the adjustment block (2), and the length adjustment assembly adjusts the distance between the vertical frame (1) and th...

Embodiment 2

[0054] like Figure 1-11 , 17 and 18 show

[0055] As described in Example 1, the side flaps are rotated clockwise relative to the longitudinal frame, so that the longitudinal frames slide toward each other and move outward, increasing the diameter of the channel. In the case of obese patients or thicker tissues, the effect of exposing the target position is also achieved. Meet the requirements for adapting to the purpose of patient size.

Embodiment 3

[0057] like Figure 12-14 shown

[0058] The length adjustment assembly includes a slider (201), a telescopic air bag (205) and a tension spring (206), the upper side of the vertical frame (1) has a chute (101), and the lower side of the adjustment block (2) A slider (201) is fixedly connected, and the slider (201) is slidably connected in the chute (101), and one of the adjusting blocks (2) is set as a thin plate (204), and the adjusting block (2) is lowered A telescopic air bag (205) is fixedly connected to one side of the thin plate (204), and a tension spring (206) is fixedly connected to the lower side of the adjustment block (2) on the side of the telescopic air bag (205). By controlling the telescopic air bag (205) Adjust the distance between the adjustment block (2) and the vertical frame (1), the upper side of the telescopic air bag (205) is fixedly connected with a connecting pipe (207), and the connecting pipe (207) is fixedly connected upward with a vertical pipe ...

Abstract

The invention discloses an adjustable channel for nucleus pulposus extraction under a single-side dual-channel mirror, and relates to the field of medical instrument assistance. The adjustable channel comprises side wing plates, adjusting blocks and longitudinal frames, wherein a through hole is formed in the middle of each side wing plate, the adjusting blocks are arranged in the middle of each side wing plate and annularly arrayed around the circle center of the through hole of the corresponding side wing plate, the adjusting blocks are connected in a sliding mode, the two sliding side faces of the adjusting blocks form an acute angle, the corresponding longitudinal frames are arranged on the lower sides of the adjusting blocks, the longitudinal frames and the adjusting blocks are consistent in shape, a length adjusting assembly is arranged between the longitudinal frames and the adjusting blocks, and the length adjusting assembly is used for adjusting a distance between the longitudinal frames and the adjusting blocks. According to the invention, the length adjusting assembly and a diameter adjusting assembly are arranged to adjust the length and the diameter of an operation establishing channel, so convenience is provided for an UBE operation.

Description

technical field [0001] The invention relates to the field of medical equipment assistance, in particular to an adjustable channel for unilateral double-channel endoscopic nucleus pulpectomy. Background technique [0002] UBE technology is an abbreviation for unilateral dual-channel endoscopic technology. It uses two channels, one endoscopic channel and one operating channel. This is the biggest difference from the single-channel technique of transforaminal endoscopy. The UBE technique is a minimally invasive endoscopic technique for the spine. It is mainly used for endoscopic minimally invasive treatment of cervical spondylosis, thoracic spondylosis and lumbar degenerative lesions. Due to the use of two channels, the operating instruments are not limited by the size, so UBE technology is the most efficient technology among various spinal minimally invasive technologies. In addition to conventional cases of various types of intervertebral disc herniation, it is especially...
