Description
Technical Field
The application relates to a medical instrument, in particular to a needle inserting point filing device for forming a vertebral pedicle arch channel.
Background
The percutaneous pedicle puncture technology has become a basic technical means of minimally invasive spine surgery, and has the advantages of small incision, less bleeding, small interference on nerve and muscle, low infection rate and the like. Complications include surgical complications resulting from poor penetration or poor placement of the pedicle cortex, including nerve and vessel damage, visceral damage, and decreased vertebral body stability.
The traditional method is operated by hands under perspective monitoring, and has the defects that in order to obtain the optimal puncture position, medical staff often needs to be exposed to rays for repeated adjustment operation, and the medical staff and a patient are exposed to more radiation exposure. The technology of applying robot-assisted artificial intelligence to pedicle screw implantation is mature day by day, the screw implantation is more accurate and safer, the ray exposure in the operation of doctors and patients is obviously reduced, and the operation is more minimally invasive.
Before the screw is implanted, a needle needs to be manually driven into the pedicle arch according to a needle inserting point determined by the auxiliary artificial intelligence of the robot. However, since the surface of the pedicle arch is not flat, when the needle is driven by hammering, the needle head slips on the surface of the bone, so that the needle driving point is shifted, and the position of the needle entering into the pedicle is not good, which causes complications.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, the present application aims to provide a needle insertion point filing device for pedicle tunnel formation, which can help to form a surface for easy needle insertion at a needle insertion point.
The application of pedicle arch passageway forms and uses needle point of entry device of filing, and it includes: a sleeve and a filing body;
the sleeve comprises a vertically formed barrel body, and handles are formed at the upper end of the barrel body in a manner of extending towards two sides;
the filing body is formed into a rod shape; the lower end of the filing body is fixedly provided with a circular truncated cone-shaped filing head; the lower surface of the filing head is a rough surface used for trimming the surface of the bone at the needle point part; the lower surface of the filing head is a plane or a downward convex cambered surface; the cross section of the upper end of the filing body is in a regular hexagon shape and is used for being clamped to a hand drill;
the file body can be installed in the sleeve body of the sleeve in an inserting and pulling mode and can rotate in the sleeve body, and the upper end of the file body extends upwards to the upper portion of the handle of the sleeve; the lower surface of the head of the filing body exceeds the lower end of the cylinder body of the sleeve and is exposed outside.
Preferably, a boss is formed in the middle of the filing body, and a plurality of beads are rotatably mounted on the boss; the boss is located within the tubular body of the cannula.
Preferably, the number of the bosses is two.
Preferably, of the two bosses, the first boss is close to the upper end of the cylinder body.
Preferably, in the two bosses, the second boss is located at the middle position between the filing head and the first boss.
Through the formation of the pedicle of vertebral arch passageway of this application with going into needle point and contusing the device, the bone surface to going into the needle point position is maintained in the sleeve through the body of contusing, creates the advantage in the bone for accurately nailing the needle into.

Detailed Description
The present invention will be described in detail with reference to the drawings.
The application of pedicle arch passageway forms and uses needle point of entry device of filing, and it includes: a sleeve 10 and a frustrating body 20.
The sleeve 10 includes a vertically formed barrel body 12, and a handle 11 is formed at an upper end of the barrel body 12 to extend to both sides. It should be noted here that the sleeve 10 is identical to the sleeve currently used for pedicle screw implantation using a robot.
The filing body 20 is formed in a rod shape; a round table-shaped filing head 23 is fixedly formed at the lower end of the filing body 20; the lower surface of the filing head 23 is a rough surface for trimming the surface of the bone at the needle point; the lower surface of the filing head 23 is a plane or a downward convex cambered surface; the upper end 21 of the body 20 is of regular hexagonal cross-section for being clamped to a hand drill.
The filing body 20 can be inserted and pulled out from the cylinder body 12 of the sleeve 10 and can rotate in the cylinder body 12, and the upper end 21 of the filing body 20 extends upwards to the upper part of the handle 11 of the sleeve 10; the lower surface of the head 23 of the body 20 is exposed to the outside beyond the lower end of the barrel 12 of the sleeve 10.
A boss 22 is formed in the middle of the body 20, and a plurality of beads 22a are rotatably mounted on the boss 22; the boss 22 is located within the tube body 12 of the cannula 10 and the bead 22a has clearance with the inner peripheral surface of the cartridge body 12 to allow the stopper 20 to rotate within the cartridge body 12. The boss 22 is used to ensure that the shaft line of the filing body 20 is substantially consistent with the shaft line of the cylinder body 11, which is beneficial to ensuring the direction of the filing body 20 and avoiding the abrasion of the outer periphery of the filing head 23 to the inner periphery of the lower end of the cylinder body 12. The number of bosses 22 is preferably two. Of the two bosses 22, the first boss is located near the upper end of the cartridge body 12. The second boss is located at the middle position between the head 23 and the first boss.
When the bone surface-repairing tool is used, firstly, the sleeve with the inner core is placed in the needle inserting position determined by a robot, the inner core is pulled out (the step is completely the same as that in the prior art), the file body is inserted into the sleeve, the file body is arranged on a hand drill, and when the file body rotates, the bottom surface of the file head trims the bone surface of the position to be punctured into a flat surface; the body is then withdrawn and the needle is inserted into the sleeve and the needle is driven accurately into the trimmed bone surface of the head. After the needle is driven in, the sleeve is taken down, the needle is taken as a guide shaft, the screw is sleeved on the needle and screwed into the bone, and then the needle is pulled out.
