A pacing lead having a lead body comprising a hollow sheath by a first lumen and an extension body extending from the lead body, the extension body having a proximal end and a distal end, the distal end having an active lead region. The extension is traversed by a second lumen, the second lumen communicating with the first lumen of the lead body so as to receive a guide wire for the implantation of the lead. The extension has an outside diameter of between 1 and 3 French. The extension distal end comprises at least one electrically isolated peripheral conductor electrically insulated except for at least two denuded areas on an outer surface of the conductor to contact a wall of a target vein, so as to form a network of stimulation electrodes electrically connected together. The lead body proximal end includes an electrical connection for the peripheral conductor.

The invention discloses a dental implantation guide plate, a drill bit and an application method thereof, and relates to the technical field of oral implantation. The dental implantation guide plate comprises a base plate identical to gum in radian; an internal jaw bone fixing plate and an external jaw bone fixing plate are respectively arranged at two sides of the length direction of the base plate in an equidirectional extending mode; a plurality of mounting holes for enabling the drill bit to enter to-be-implanted gum are formed in the base plate; and one end, away from of the internal jawbone fixing plate, of each mounting hole is provided with a wedge groove for forming a negative pressure drainage cavity. After the implantation guide plate and the gum are fixed, the drill bit can extend into the mounting holes and drill the gum, cooling water directly enters the implantation area of the gum from the mounting holes, and then, the cooling water cools the gum; and in a drilling process, a negative pressure drainage cavity is formed for each wedge groove through a vacuum suction device in the position of the implantation guide plate, and the negative pressure drainage cavity guides watery blood and crushed bones in the implantation area to be discharged, so that the discharge velocity is higher, the residues are less, and the drilling process is fast, stable and accurate.

The invention discloses a full-mouth edentulous implant repair system and method and relates to the technical field of edentulous implants. The full-mouth edentulous implant repair system comprises asupporting table, a guide pipe and a screw, wherein a fixing block is fixedly connected to the outer side of the supporting table, the top of the fixing block is fixedly connected with a supporting surface through a fixing bolt, the guide pipe is fixedly connected to the inner side of the supporting table, the screw is in threaded connection with the interior of the guide pipe, a threaded groove is formed in the surface of the screw, a base table is arranged at the top of the screw, and the top of the screw is fixedly connected with the base table through a connecting nail. According to the full-mouth edentulous implant repair system and method, the system is designed and digitally processed, the operation risk of doctors and the working strength of technicians during post-operation restoration are effectively reduced, the implant efficiency is improved by adopting a whole tooth structure, the stability of implanted teeth is better guaranteed, the problem of breakage of patients in theuse process is avoided, the structure is simple, and the improvement of the working efficiency is facilitated.

The halo implant technique described herein employs a halo implant mask that creates a halo implant shadowing effect during halo dopant bombardment. A first transistor device structure and a second transistor device structure are formed on a wafer such that they are orthogonally oriented to each other. A common halo implant mask is created with features that prevent halo implantation of the diffusion region of the second transistor device structure during halo implantation of the diffusion region of the first transistor device structure, and with features that prevent halo implantation of the diffusion region of the first transistor device structure during halo implantation of the diffusion region of the second transistor device structure. The orthogonal orientation of the transistor device structures and the pattern of the halo implant mask obviates the need to create multiple implant masks to achieve different threshold voltages for the transistor device structures.

The invention discloses a guiding device for oral implantation surgery, which relates to the technical field of oral implantation and aims to solve the technical problem in the prior art that the implantation guide plate needs to be replaced many times, resulting in inaccurate positioning. The main points of the technical solution include the implantation guide plate and The positioning part is provided with a mounting opening on the top wall of the planting guide plate, and the positioning piece is detachably arranged in the mounting port of the planting guide plate, and a locking piece is provided on the top wall of the planting guide plate; when the patient needs to perform planting surgery, the planting guide The plate is clamped on the teeth, and the positioning part with the sleeve is fixed in the installation opening of the implant guide plate, and the positioning part is locked by the locking part, so that the drill bit can be transferred into the patient's mouth along the sleeve, and when it needs to be replaced When drilling, remove the positioning part, replace the sleeve with a suitable size, and then lock the positioning part through the locking part, which can replace the installation method of multiple assembly and disassembly of the positioning template, which is conducive to reducing positioning errors and reducing the need for precise implant teeth. impact.

The invention relates to the technical field of tooth implantation, in particular to manufacturing and mounting of temporary teeth and more specifically provides an in-place mounting structure and anin-place mounting method for the temporary teeth. The in-place mounting structure for the temporary teeth comprises temporary teeth and an implantation guide plate, the temporary teeth are mounted onthe implantation guide plate, at least three retention pillars in different directions are arranged on the implantation guide plate, and a coaxial retention nail hole is formed in each retention pillar. According to the in-place mounting structure and the in-place mounting method for the temporary teeth, the position, direction and occluding relation of the temporary teeth in a mouth can be adjusted before a patient puts on the temporary teeth in the mouth, the in-place mounting time of a pair of half-mouth temporary teeth is shortened to be only about 1 hour from original 3-4 hours, the in-place mounting time of the temporary teeth is greatly shortened, and pain of the patient can be better relieved.
