Front and back lock

InactiveCN102080470ASolve slipping and idlingAvoid deformationCylinder locksEngineeringMechanical engineering
The invention discloses a front and back lock comprising a lock body (1), a front lock cylinder (2), a spring (3) and a keyhole (22); the front lock cylinder (2) is internally provided with an atypical spring (4) with a side wall notch (5); the front lock cylinder (2) is internally provided with a side spring hole (7) communicated with a spring hole (6); the side spring hole (7) is internally provided with a side spring (8); a rear lock cylinder (9) is arranged in the rear of the front lock cylinder (2) and is provided with a rear spring hole (10) corresponding to the rear end of the side spring hole (7); the rear spring hole (10) is internally provided with a lock spring (11); and the lock body (1) is internally provided with a lock body spring hole (12) corresponding to the lock spring (11). The front and back lock is characterized in that a sharp corner (13) is arranged at the front end of the lock spring (11), or the sharp corners (13) are simultaneously arranged at the front end of the lock spring (11) and the rear end of the side spring hole (7). The lock ensures the stable leakage of the front lock cylinder (2) and the rear lock cylinder (9) by utilizing the mutual occlusion of the sharp corner (13) at the front end of the lock spring (11) and the sharp corner (13) at the rear end of the side spring hole (7). When the lock is unlocked by using an unlocking tool, the front lock cylinder (2) is idle, thereby effectively preventing from being twisted and pulled by the unlocking tool and rotated by external force to open and increasing the safety of the lock.

Self-tapping biocompatible interference bone screw

ActiveUS20090198288A1Limited amountPotential confusionSuture equipmentsLigamentsEngineeringKeyhole
A biocompatible interference screw for soft tissue or bone-to-bone fixation comprises a screw body extending from a screw head to a distal tip of the screw. The screw body has an outer surface, and comprises polyether-ether-ketone (PEEK) material. Advantageously, the body outer surface has a textured surface finish for substantially improving pull-out strength of the interference screw. The textured surface finish is textured, in preferred embodiments, with a minimum of approximately 16 micro inches of surface roughness. The screw head comprises a tapered square keyhole for receiving a distal end of a driver instrument. The screw comprises a series of threads, which have a relatively smooth profile, in order to prevent graft tissue laceration as the screw is being inserted. The distal tip of the screw body comprises a narrow tip, and a distal end of the screw body is angled inwardly toward the narrow distal tip.

Method and systems for real-time active refinement of search results

A computer utility for any kind of search engine or data that provides a graphical user interface for displaying search results and live refinement of the results, by automatic changing and / or offer to change the results list in real time, according to the user's demonstrated navigational interests.The graphical user interface includes resizable windows, configured to display the contents of the links (“keyhole windows”) The search results list may be dynamically altered by real time re-searching according to the reaction of and browsing movements of the user examining the search results. In the keyhole windows users may independently browse through and view content contained therein including links.This invention detects user intention based upon its viewing and browsing of linked websites inside the keyhole windows. Thus, the user can more easily browse through the most relevant websites for him.This invention may also support viewing and browsing through any kind of links content which may be found in other software programs for example, e-mails, games, advertising, web search results, data bases, Internet Protocol Television (IPTV) or index lists giving real-time re-searching of any kind of search results or index lists thereby making the user's search more efficient and time saving.In the case of advertising, the user will be presented with selected advertising more suitable to his needs and desires and the advertiser will catch an audience with an initial sympathy towards the product being advertised.

Image guided robotic system for keyhole neurosurgery

A novel image-guided system for precise automatic targeting in minimally invasive keyhole neurosurgery. The system consists of a miniature robot fitted with a mechanical guide for needle, probe, or catheter insertion. Intraoperative, the robot is directly affixed to a head clamp or to the patient skull. It automatically positions itself with respect to predefined entry points and targets in a preoperative CT / MRI image following an anatomical registration with an intraoperative 3D surface scan of the patient facial features and a registration jig. The registration procedure is a novel three-way scheme, in which the intraoperative surface scan including the registration jig is matched to a model generated from the preoperative CT / MRI image, the robot position is known in relation to the registration jig, and the entry and target points are known from the preoperative CT / MRI image, such that the robot position can be related to the entry and target points.
