The present application relates to the technical field of oral tools, and discloses an oral implant angle fitting, adjusting, installing tool, which comprises a universal implant mobile phone and a mobile head, a washing assembly is arranged on the outer side of the universal implant mobile phone, and an air curtain assembly is arranged on the outer side of the universal implant mobile phone; a protection assembly is arranged on the outer side of the universal implant mobile phone; the washing assembly comprises a first fixed plate, the first fixed plate is fixedly connected to the outer surface of the mobile head, a plurality of liquid outlet heads are arranged in a circumferential array on one side of the outer surface of the first fixed plate, the liquid outlet heads are all arranged obliquely, and the liquid outlet heads are obliquely directed towards the position of the drill bit of the mobile head; the present application aims to solve the problem that, when performing surgery on the elderly, bone chips generated by drilling are accumulated in the deep part of the cavity, which not only causes the drill needle to jam and deviate, the implant path to deviate from the preset angle, but also hinders the observation of the bone wall morphology and anatomical structure by the operator, and increases the risk of bone wall penetration and nerve and blood vessel injury.

The application discloses a bone regeneration kit and implant system for immediate implantation, and belongs to the technical field of oral implant medical devices. The kit comprises a patient personalized component and a universal component; the patient personalized component comprises a segmented personalized abutment and a rigid barrier membrane, the abutment comprises, from top to bottom, a transgingival forming part, a titanium mesh fixing part and an implant connecting part, and the rigid barrier membrane is fixed to the titanium mesh fixing part through a mounting hole; the universal component comprises a plasma matrix preparation component and a bone crumb collector. The application further provides an implant system comprising the kit, an implant and a complete autologous plasma matrix bone block. The rigid barrier membrane is directly fixed to the abutment to form a three-level rigid support, and the titanium nail fixing is omitted; the transgingival forming part of the abutment is customized based on digital scanning to realize soft tissue simultaneous sealing and aesthetic shaping; the bone crumb collector scrapes autologous bone crumb from the bundle-shaped bone area of a tooth extraction socket, and the autologous bone crumb is mixed with autologous plasma matrix to form a bone block without adding exogenous materials. The application realizes the synergistic effect of rigid maintenance of bone space, complete autologous bone regeneration and soft tissue simultaneous forming.

The application discloses a craniotomy drill, which comprises a supporting and positioning assembly, a driving component, a drill bit and a control component; a limiting rod is arranged on a frame; a driving machine one is in sliding connection with the limiting rod, and a telescopic end of an electric telescopic piece is connected with the driving machine one; the drill bit is connected with an output rotating shaft of the driving machine one; an opening is arranged on a side wall of the drill bit, and a flexible push piece is embedded in the opening; a detection end of a torque sensor is connected with the output rotating shaft, and the driving machine one, the electric telescopic piece and the torque sensor are electrically connected with a controller. The limiting rod can abut against a skull, so that the drill bit cannot be dislocated; before the limiting rod abuts against the skull, the drill bit is precisely positioned by using a positioning rod; after the drill bit is positioned, the drill bit can be fed at a certain speed; when the drill bit is about to drill through the skull, the driving machine one and a driving machine two can immediately stop rotating; bone scraps on the outside of the drill bit can be pushed by the flexible push piece to a region far from the opening position, so that the bone scraps cannot fall into the skull.

Apparatuses and methods for a flexible obturator for use with an access assembly of an intraosseous device are disclosed. The flexible obturator can include elastic properties and a relatively low column strength, a relatively low shear strength, and / or a relatively high compression strength. The obturator can prevent bone chips and tissue from obstructing the needle lumen when the obturator is supported in the needle. When removed from the needle, the obturator can deform under force to prevent accidental needle sticks. The flexible obturator can define a radially symmetric profile and can conform to the interior profile of the needle lumen. The flexible obturator can extend beyond the distal tip of the needle and be trimmed to be flush with the bevel of the needle. This simplifies the manufacturing process, allowing a single size of obturator to fit multiple sizes of needles.

The application discloses a pedicle screw and a pedicle screw kit. The pedicle screw body is provided with a first channel, a plurality of second channels and a liquid guide arranged in the second channel. The first channel penetrates the head and tail of the pedicle screw. The first end of the second channel is in communication with the first channel, and the second end of the second channel extends to the side wall of the pedicle screw. The liquid guide protrudes from the surface of the side wall of the pedicle screw. The second channel is configured to allow external substances to enter from the second end and contact the liquid guide. The liquid guide is configured to absorb the liquid in the first channel and conduct the liquid to the side wall of the pedicle screw. The second channel is arranged to facilitate the entry of bone chips. The liquid guide is arranged in the second channel to guide the growth direction of the bone in the pedicle screw, so that the pedicle screw and the bone are stably anchored.
