An electrically powered surgical instrument includes a surgical end effector having a surgical procedure effecting actuation assembly. A handle is coupled with the end effector. An electric motor is disposed within a shell of the handle and has power terminals and a drive train actuating the assembly when the motor is supplied with power. A break-before-make power supply switch at the handle selectively controls supply of power to the motor. A post-termination braking circuit electrically short-circuits the power terminals when the switch does not supply power to the motor. A method for post-termination braking of an electrical motor utilizes the permanent magnetic field of the motor to counteract an inertia-induced over-stroke characteristic of the motor, drive train, and / or actuation assembly after powered operation by short-circuiting the still-spinning motor to create an electrically generated magnetic field in opposition to the permanent magnetic field upon ceasing supply of power to the motor.

A compact, low-profile surgical retractor (100) avoids the need for a bulky frame. The retractor includes retractor blade components (110, 120, 130, 140, 150, 160) joined pivotally. A cable (170) is guided by each retractor blade component. A winding mechanism (180), such as a spool, is carried by one of the retractor blade components (120) for winding up the cable to cause the retractor blade components to transition from a closed position to an open position. The winding mechanism may be actuated by a detachable handle (200). The retractor blade components may be unitary, injection-molded pieces. The retractor blade components may be fixed pivotally, such as by pins, or pivotally joined by living hinges. A less-invasive surgical method is also provided in which the retractor is inserted into the body through an incision.

A method for encrypted authentication of interchangeable parts of a surgical instrument includes providing a surgical end effector at a distal end of a handle of the surgical instrument and electrically connecting an authentication controller within the handle to a receiving portion of the end effector. An interchangeable part is removably placed at the receiving portion. The interchangeable part is authenticated with the authentication controller when the interchangeable part is seated in the end effector.

A method for effecting a tissue-compressing surgery at a user-selected compression force provides an electrical switch having switching states changed solely by mechanical movements. The switch is mechanically coupled with an adjustable biasing device retaining the switch in one state until a force greater than the bias device is imparted to the switch. The switch is in line with a tissue-compressing device to place a proportional amount of compression force on the switch as imparted upon the tissue. The biasing device is set to a desired state-changing tissue compression force so that the switch changes its state when the force on the switch is at least the desired force. Tissue compresses until a force imparted on the switch at least equals the desired state-changing tissue compression force and, at such time, the switching state changes and, thereafter, a surgical procedure is carried out on the compressed tissue.

The invention relates to an LED package for facilitating color mixing using a diffuser and a manufacturing method of the same. The LED package includes a substrate with an electrode formed thereon, and an LED chip mounted on the substrate. The LED package also includes an encapsulant applied around the light emitting diode chip, containing a diffuser. The LED package further includes a lens part disposed on the light emitting diode chip and the encapsulant to radiate light in a wide angle. The LED package allows light from the light emitting diode chip to be emitted out of the package without distortion. The invention allows light to exit through the encapsulant containing the diffuser and the lens part, achieving uniform diffusion and emission of light from the LED chip, thereby increasing a radiating angle and obtaining a uniform light source.

A dermal punch device for automatically extracting a sample of tissue of a predetermined size and shape from a body comprising a retractable cutter and a sutureless biopsy closure mechanism that includes a wound closure fastener member adapted to be disposed over a biopsy region after the performance of the biopsy, wherein wound closure fastener member is applied without the need of several instruments to seal the wound. The wound closure fastener member is dispensed by a sutureless biopsy closure dispenser located at the same distal end of the biopsy punch device surrounding the biopsy punch cutter assembly avoiding the need of separates instruments, reducing the wound closing steps and surgical procedure time.

The invention discloses an attapulgite argil powder with an air purifying function. The technical scheme is as follows: the attapulgite argil powder with an air purifying function is prepared from high-viscosity attapulgite clay, an attapulgite constant-humidity conditioner, a natural mineral adsorbing / filtering agent, Cacumen Biotae, aluminum silicate fiber and polyacrylamide. The attapulgite argil powder is prepared by the following steps: pulverizing the materials, soaking and aging to obtain a wet mixture, extruding the wet mixture into a strip, airing the strip, pulverizing to obtain powder, and packaging to obtain the finished product. The attapulgite argil powder has favorable cohesive property, plasticity, thixotropy, fire resistance and thermal stability; the pottery prepared from the attapulgite argil powder with an air purifying function contains a great deal of micropores and activated carbon, thus, has the characteristics of low shrinkage, no cracking or deformation and favorable adsorbability, and can effectively adsorb formaldehyde, ammonia, benzene and other harmful substances in the air, thereby protecting the environment and improving good health of people. The invention is suitable for producing pottery artware with an air purifying function.
