A system and method for performing electrocautery is provided in which the surgeon need not worry about injuring the patient by placing the electrocauteral blade too close to the retractor. This system and method is implemented by forming at least the retracting end of the retractor from an electrically non-conductive material. In one embodiment of the invention, the retractor is formed from the electrically insulating material, such, for example, plastic, especially heat resistant clear plastic. Thermosetting resins, and other polymers particularly those having filters to increase heat resistance are preferred. The electrically non-conductive retractor is used to retract the skin as the electrocauteral blade is used to cut and / or coagulate. Methods in accordance with invention are particularly useful when the initial incision is small, such as in the one to five, preferably two to four inch range. Methods and systems in accordance with the invention are particularly preferred during cosmetic surgery and / or surgery on the breasts, head or neck. Accordingly, it is an object of the invention to provide an improved system and method for performing electrocautery.

A medical pillow suitable for neck operation, trachea cannula, and insertion of fibrobronchoscope as it can make the head at sniff position is composed of a lower cushion with an inclined front end face and a concave curved back end face, and an upper cushion with a smooth top surface and a convex curved bottom surface matched with said concave curved back end face of lower cushion. The top surface of upper cushion and the concave curved surface of lower cushion have respectively a hole.

The invention discloses a multifunctional head and neck control type mouse, which comprises an ear hook, a guide device is arranged at the lower end of the ear hanger, and the guide device is connected with a guide instrument. When the present invention is used, the ear hook is connected with the head of the user, and the head moves up, down, left, and right to drive the guide device to move accordingly. The guide meter senses this movement and converts this movement signal into a corresponding signal, which is transmitted to the computer in a wired or wireless form. When the present invention is used, the movement of the head and the neck is mainly used to fully liberate the limbs, and it is especially suitable for disabled persons.

The invention relates to the technical field of glass melting furnace structures, and discloses an arch structure of a glass melting furnace locking neck. The structure is characterized in that the structure comprises a plurality of sequentially bonded bricks; the bricks are wedge-shaped; and the brick on the outer side of the arch structure abuts against a tank wall of the melting furnace. The arch structure provided by the invention is wedge-shaped, and the brick on the outer side is stressed by extrusion force from the outside. Therefore, bricks in the arch structure can be firmly bonded. Even if the arch structure is in a high-temperature environment for a long time, and is corroded by sulfur and alkaline atmospheres, the bricks do not fall. The bricks are prevented from falling into glass liquid in the melting furnace, such that glass quality is not affected. The arch structure do not need to be fixed by using steel structures, such that energy consumption of the melting furnace is reduced, locking neck operation space is increased, and melting furnace stability and safety are improved.

The invention discloses an automatic indentation necking system, and relates to the technical field of automation. The system comprises a necking machine, hydraulic oil pipes and a hydraulic station,wherein the necking machine is driven by a traditional hydraulic cylinder type power source; the necking machine adopts a piston and piston rod structure to drive a top cylinder; the top cylinder andan indentation knife are matched through an inclined plane to realize relative movement, so that the force in the vertical direction is converted into the extrusion force of the indentation knife to the center, and indentation necking operation on a structure to be necked arranged in the center is realized. The system is simple in operation and easy to realize, can realize effective and reliable connection among components without introducing other connection accessories, and has very important significance for connection among components in a device with compact structure.

The invention aims at providing a puncture outfit with a demisting tube guide structure, and the puncture outfit is capable of effectively improving the neck operation efficiency of an endoscope. The puncture outfit comprises the puncture outfit as a main body and the guide structure, wherein the guide structure is communicated end to end; the head and the tail of the guide structure are flush with those of a puncture sheath of the puncture outfit; the guide structure is attached to the puncture sheath to form a whole body. The puncture outfit has the advantages that (1) a demisting tube can be conveniently arranged in the puncture outfit; (2) a good sealing effect can be achieved; (3) the demisting tube can synchronously move along with the endoscope, so that smoke near the endoscope can be removed in time, the monitoring effect of the endoscope is prevented from being interfered, and the operation time is effectively shortened; (4) the puncture outfit is simple in structure and convenient to operate.

The invention relates to medical apparatuses and instruments, in particular to a pressure dressing device used after a thyroid operation. The pressure dressing device used after a neck operation comprises a fixed belt, a support frame board, an H-shaped pressure board, a pressure water sac (comprises an elastic ball sac, a pressure gage, a water injection joint and a pipeline of the water injection joint). In time of using the pressure dressing device used after the neck operation to dress, firstly, a cutting opening is dressed conventionally, and a negative pressure drainage pipe (drainage bar) is connected. The pressure dressing device is fixed on the neck through the support frame plate from rear to front, and meanwhile, the positions of the pressure board and the water sac are adjusted so that the center of the pressure dressing device directs at the center of area needing oppressing. The pressure gage is observed simultaneously when the water injection joint injects water so as to enable pressure of a wound surface (water sac) of the neck to be adjusted within a safe range required by an operator. The pressure dressing device used after the thyroid operation has the advantages of accurately balancing the wound surface needing oppressing after the oppressing operation, and oppressing on adjacent portions, especially on tracheas is avoided. Therefore, under the condition that the problem of oppression after the neck operation is solved, respiratory function of a patient is prevented from being affected and discomfort of the patient after pressure dressing after the operation is greatly relieved.

The invention discloses a portal reduction device for an automatic oil coating process. The portal reduction device comprises a portal reduction mechanism and an oil coating mechanism. The portal reduction mechanism comprises a portal reduction base and a portal reduction pressure cylinder fixed relatively to the portal reduction base. A retractable operation end at the bottom of the portal reduction pressure cylinder is provided with a portal reduction pressure head. The upper end of the portal reduction base is provided with a portal reduction Half-type part. The portal reduction Half-type part is located below the portal reduction pressure head and comprises a cylindrical Half-type sleeve and a cylindrical Half-type assembly arranged in the Half-type sleeve. The cylindrical Half-type assembly comprises multiple arc-shaped Half-type blocks arranged in a central symmetry way. The oil coating mechanism comprises an outer sleeve oil coating pipe arranged on the portal reduction pressure head and an inner sleeve oil coating pipe arranged on the portal reduction base. An oil outlet of the outer sleeve oil coating pipe is located above the cylindrical Half-type assembly. An oil outlet of the inner sleeve oil coating pipe is provided with a fuel injector. The portal reduction device realizes simultaneous automatic portal reduction and anti-rust oil coating and has the advantages of easy control of operation quality and high labor efficiency.
