The invention discloses synchronous machining equipment for insections of needle forceps, which belongs to the technical field of needle forceps machining and comprises a machining table for synchronously machining two forceps handles, two groups of assembly frames are arranged on the machining table, and four mounting seats are mounted on the assembly frames. Through the arrangement of the tooth adjusting assembly, the cooperation of the adjusting rack, the adjusting gear and the assembling frame can be used for forcing the double clamp handles to move and deflect completely synchronously, the insection phase difference caused by traditional split machining is eliminated, and tooth dislocation after assembly and clamping needle slipping in the clinical use process are avoided; wet friction testing can be carried out in the state that the two forceps handles are assembled, puncture resistance similar to dermis is provided by simulating a tissue membrane, whether clamping force for machining insections is qualified or not is judged according to whether a drop point is deviated or not after puncture of a suture needle, and whether the lateral slippage risk of the suture needle is high or not is judged according to whether an elastic membrane is deformed or not, so that detection is more comprehensive.

A transdermal permeant delivery system for delivering at least one permeant to a tissue membrane of an individual comprises: a filament array having a plurality of filaments disposed in a perforated region and configured to deliver thermal energy to the tissue membrane to form a plurality of micropores; an applicator electrically connected to the filament array and configured to supply electrical energy to the filaments to generate the plurality of micropores in the micropore region; and a patch configured to be applied to the micropore region and releasably containing at least one permeant. A method of treatment comprises administering the permeant in the form of a drug to an individual in need thereof using the transdermal permeant delivery system.

A transdermal permeant delivery system for delivery of at least one permeant into a tissue membrane of a subject comprises a filament array having a plurality of filaments that are disposed in a poration area and configured to deliver thermal energy to the tissue membrane to form a plurality of micropores; a applicator electrically connected to the filament array and configured to supply electrical energy to the filaments in order to create the plurality of micropores in the micropore area; and a patch configured for application on the micropore area and for releaseably containing at least one permeant. Method of treatment comprise using the transdermal permeant delivery system to administered a permeant in the form of a drug to a subject in need thereof.

The application discloses a tissue membrane positioning drill and relates to the technical field of biomedical engineering, which comprises a drilling part, a reaming part, a handle part and a connecting part, the reaming part is connected with the drilling part, straight blades are symmetrically arranged on the two sides of the reaming part, the reaming part is further provided with two top blades, the two top blades are symmetrically arranged, the top blades are arranged perpendicularly to the center line of the tissue membrane positioning drill, the outer diameter of the straight blade is larger than the diameter of the drilling part, the handle part is connected with the end of the reaming part away from the drilling part, the connecting part is arranged on the handle part, and the connecting part is used for transmission connection with the power output end of a medical drilling mobile phone. The integrated structure integrates the drilling, reaming and flattening functions in the same instrument, a plurality of different surgical tools are not needed for preparation before operation, the surgical operation process is greatly simplified, the initial alignment is taken as the only reference throughout the whole process, secondary adjustment and positioning are not needed, the deviation risk caused by multiple alignment is eliminated from the root, and the implantation precision and the retention stability are effectively improved.
