Embodiment 1

[0048] A specific embodiment of the present invention discloses a lateral casing drill, such as Figure 1-7 shown. The lateral cannula drill is a hollow cylinder, including a first end and a second end, the outer wall of the first end is provided with a correction part 7 for modifying the bony access, the first end is placed in the body, and Has a specific shape that adapts to the internal structure of the human body.

[0049] Compared with the prior art, the lateral trocar drill provided in this embodiment can effectively correct the bony access, so that the surgical instrument can smoothly enter the body to reach the designated position, or expand the range of motion of the surgical instrument, broaden the field of vision, and make the nerve Within the field of view of the endoscope, avoid surgical instruments from damaging nerves during the process of reaching the designated position.

[0050]Specifically, the use of an electric drill to correct the bony access, on the on...

Embodiment 2

[0056] Considering the intricate internal structure of the human body, and because of the different surgical methods and surgical approach directions, different shapes need to be designed, on the one hand, to ensure a high reaming speed, and on the other hand, to ensure the safety of the operation. In this embodiment, the shape of the first end of the lateral casing drill includes oblique type, bifurcated type, duck tongue type and semi-elliptical type, such as Figure 1-7 shown. The lateral casing drills of the above four shapes can well adapt to the internal structure of the human body, thereby increasing the reaming speed and shortening the operation time. And because the shape of the end of the lateral casing drill adapts to the internal structure of the human body, it can reduce the damage of the lateral casing drill to other parts of the human body in the process of correcting the bony access, greatly improving the safety of the operation.

[0057] Specifically, the obl...

Embodiment 3

[0065] Another embodiment of the present invention discloses a method for operating a lateral casing drill, which is used to operate the lateral casing drill of the first or second embodiment, including the following steps:

[0066] Step 1: Determine the direction and pathway that the surgical instrument needs to enter;

[0067] Step 2: inserting surgical instruments into the access;

[0068] Step 3: When the surgical instrument cannot be placed smoothly or the endoscopic field of view is not good although the surgical instrument can be placed smoothly, place the lateral cannula drill at the position where the bony access needs to be corrected;

[0069] Step 4: Manually operate the lateral cannulated drill to polish the bony access;

[0070] Step 5: Replace the lateral casing drill with different end shapes and different types of correction parts and continue grinding until the surgical instrument can pass through the bony access to the designated position smoothly.

Abstract

The present invention relates to a lateral sleeve pipe drill and an operation method, belongs to the technical field of surgical instruments, and solves problems that in the prior art, bone passages cannot be effectively corrected and the prior art is liable to be corrected excessively and time-consuming, and damages important functional bone tissue morphology. The lateral sleeve pipe drill is a hollow cylindrical shape, and comprises a first end portion and a second end portion, an outer wall of the first end portion is provided with a correction portion for correcting the bon passages, and the first end portion is placed in body and also has specific shapes adapted to different surgical methods and surgical approach directions and human body internal structure. The operation method of the lateral sleeve pipe drill comprises the following steps: step 1: determining entering directions and passages needing by the surgical instruments; step 2: placing the lateral sleeve pipe drill at positions where the bone passages need to be corrected; and step 3: manually operating the lateral sleeve pipe drill to polish the bone passages until surgery field is well exposed, and the surgical instrument can smoothly pass through the bone passages to reach the designated positions. The lateral sleeve pipe drill realizes rapid and effective correction of the bone passages and improves safety ofsurgeries.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a lateral casing drill and an operating method. Background technique [0002] Osteoarthritis is more common in middle-aged and above. It is generally believed that due to physical weakness and degenerative changes after middle age; standing or walking for a long time and holding a certain posture for a long time, due to muscle pulling or avulsion, bleeding, hematoma organization, forming spines or lip-like bones Hyperplasia, also known as bone spurs or hard osteophytes. Spinal disc herniation, Asian population is often accompanied by spinal stenosis, hyperosteophyte, and nerve root adhesion. Spinal endoscopic treatment has become an important surgical access for spinal diseases, and the combined minimally invasive treatment of the spine has broad prospects. During endoscopic treatment of the spine, it is often necessary to adjust the position and angle of the bony...
