Adjustable electrocautery surgical apparatus

An adjustable electrocautery surgical apparatus for selectively delivering electosurgical coagulation and cut current from an electrosurgical generator to a surgical site is provided comprising an elongated body, an extension member passing at least partially through the elongated body, a track in the elongated body for guiding the extension member, an electrode blade attached to the extension member for cutting or coagulating tissue, and an adjustable lock coupled to the extension member for selectively adjusting the position of the extension member and electrode blade relative to the elongated body and for locking the extension member and electrode blade in a selected position. A longitudinal channel passes through a sidewall of the elongated body member. A plurality of stops are positioned in the channel for providing a sequence of stop positions between maximally retracted and maximally extended positions of the apparatus. The adjustable lock is slidably positioned in the longitudinal channel of the elongated body member so as to selectively engage the stops and thereby lock the electrode blade in a selected stop position between the maximally retracted and the maximally extended positions. The apparatus is further provided with means for electrically coupling the electrode blade to the coagulation and cut currents of the electrosurgical generator, such that coagulation or cut current, or a combination thereof, can be selectively delivered to the electrode blade.

Trocar and cannula assembly having conical valve and related methods

A trocar system for endoscopic surgery, cap assembly, and related methods are provided. The cap assembly includes a valve housing with an opening formed in line with an axis of the valve housing. The cap assembly also includes a valve positioned adjacent the opening of the valve housing. The valve includes a valve body with an annular-shaped valve opening for receiving elongate tools with differing diameters so that a seal is maintained between the valve opening and any of the plurality of elongate tools. The valve body includes a proximal valve section including a valve ring and positioned within the valve housing and includes a distal valve section extending axially from the proximal valve section. The distal valve section includes a valve extension having a proximal end portion, a distal end portion, and a substantially conically shaped medial portion connected to and extending therebetween. A valve opening is positioned in the distal end portion of the valve extension that is adapted to individually and separately receive the elongate tools so that when any one of the elongate tools is positioned through the valve opening, a seal is maintained between peripheries of the valve extension surrounding the valve opening and outer peripheries of the inserted elongate tool.

Injection-molded part forming method requiring two stages of core pulling

ActiveCN107009584AFirmly connectedReliable core pulling stepsEngineeringInjection moulding
The invention discloses an injection-molded part forming method requiring two stages of core pulling. During mold splitting, a core pulling oil cylinder drives a primary core pulling sliding block slidingly connected with the interior of a secondary core pulling sliding block to slide backwards, and the primary core pulling sliding block then drives a core pulling spindle slidingly connected with the primary core pulling sliding block to move backwards, so that primary core pulling is completed; the core pulling oil cylinder continues to act to pull the secondary core pulling sliding block to move backwards through the primary core pulling sliding block, so that secondary core pulling is completed; then, a product is ejected out of a movable mold; the core pulling oil cylinder acts backwards to allow the primary core pulling sliding block to move forwards, then to drive the core pulling spindle to move forwards and to stretch out of the forming end of the secondary core pulling sliding block; the core pulling oil cylinder continues to act to drive the secondary core pulling sliding block and the core pulling spindle to synchronously move forwards to reset, by this time, injection molding of a next product can begin. With the adoption method, a mould structure can be simplified, lateral core pulling in two any directions on one side of a product can be adapted, and backward movement of the core pulling spindle and the sliding blocks can be avoided.
