The seedling inserting device is simple in structure, convenient to operate and long in service life, automatic seedling insertion of the kelp seedling gripper can be achieved, and the seedling insertion efficiency of a seedling inserting machine is improved.

The invention provides a method for preparing the surface of an implant with a multi-scale porous complex structure, which is a method for preparing the surface of a titanium-based implant with antibacterial and osteogenic functions. Treated by the method to simulate the morphology environment of new bone formation in the body under physiological conditions, this surface can not only accelerate the osseointegration of the implant surface and contribute to the long-term stability of the implant, but also has significant antibacterial properties, which can inhibit the infection at the initial stage of implantation , can further improve the success rate of planting. The present invention creates a micro-nano composite pure titanium implant surface with both osteogenic and antibacterial properties. It has a three-dimensional multi-scale complex structure implant surface, and the surface has a higher osteogenesis than SLA, which is the most widely used clinically. Activity and excellent antibacterial performance, has a wide range of application prospects. It is of great significance for expanding the indications for oral implants, shortening the course of implant restoration, reducing implant-related infections, and improving the success rate of implants.

The invention discloses an oral implant. The oral implant comprises an outer shell body and an implantation hole arranged inside the outer shell body, the outer shell body comprises a cylindrical mainbody part with an external thread, a circular truncated cone-shaped inclined shoulder part arranged on the top of the main body part, and a hemispherical spherical bottom part disposed at the bottomof the main body part. A first thread region and a second thread region are disposed on the main body part from the top to the bottom, and the pitch of the first thread region is smaller than the pitch of the second thread region. The implantation hole includes a tapered hole and an internal hexagonal hole, the tapered hole is arranged downward from the top end of the inclined shoulder part, the internal hexagonal hole is arranged at the bottom of the tapered hole, the cross-section of the internal hexagonal hole is internal hexagonal, and the maximum diameter of the inner hexagonal hole is smaller than the smallest diameter of the tapered hole. The oral implant has good initial stability and high planting success rate, and bacterial sealing of the implant and a base is good, the connection is more stable.

The invention discloses a fixing device for an oral cavity, a dental jaw tracker and an implantation navigation system. The fixing device comprises a first part, a second part and a connecting part for connecting the first part with the second part; the first part, the second part and the connecting part form a clamping space to clamp teeth in a non-implantation region; when the fixing device is in a clamped state, the connecting part is in an initial state; when the fixing device is in a removed state, the connecting part changes from the initial state to a deformation state to assist the first part and the second part in separation. The fixing device disclosed by the invention has the following advantages: (1) the fixing device can firmly fix the teeth in the non-implantation region andis hard to loosen, so that the navigation accuracy is improved; (2) a technician does not need to manufacture extra accessories; the implantation operation can be performed on the day, so that the implantation treatment period is shortened; (3) after a fixing device package is sterilized, the fixing device is unpacked and directly used; water bath heating is not needed, so that the risk of surgical infection is reduced, and the implantation success rate is increased; (4) the removal process is simple and convenient.

The invention belongs to the field of breeding methods for perennial forage corn, and specifically discloses a method for improving the success rate of planting perennial forage corn, which mainly involves reducing the number of tillers to 30 to 50 after harvesting in autumn and before turning green in the next year. Plants are dug up, then cut from the base into individual stems, and established. The planting survival rate of the perennial forage corn in the method of the present invention can reach 94%, which is significantly higher than the 80% survival rate of the current spring green plant planting; secondly, the present method is beneficial to seedlings because of the early planting time growth and tillering, and a long growth time, therefore, the annual biological output can reach 94.45t / hm 2 , which is significantly higher than the biological yield of 81.34t / hm by the method of replanting green plants during the Spring Festival 2 In addition, the inventive method has a high survival rate, reduces heavy matters such as transplanting in spring, slowing down seedlings, checking seedlings and replanting, and significantly reduces production costs.

The invention relates to an osteotome sinus floor elevation reamer for dental implants. The reamer comprises a drill pipe, wherein a power connector is arranged at the tail end of the drill pipe, a hole is formed in the side surface of the front end of the drill pipe, a telescopic rod is arranged in the hole, the outer end of the telescopic rod penetrates out of the side surface of the drill pipe, abrasion patterns are arranged on the outer end surface of the telescopic rod, the inner end of the telescopic rod is hinged with one end of a connecting rod, the other end of the connecting rod is hinged with a rotating disc, the rotating disc is connected with a worm gear through a rotating shaft, the worm gear is meshed with a worm, one end of the worm penetrates out of the dill pipe, and a counterbore is formed in the end. The reamer has the obvious advantages as follows: the telescopic rod can stretch or retract, the local reaming requirement of the tail ends of drilled holes can be met, more bone substances can be arranged, the implanting success rate is high, and the reamer is safe.
