Sheathed cutting device. An exemplary device for discreetly piercing a skin of a patient can comprise a body having a proximal end and a distal end, a cutting member attached to a plunger, the cutting member and the plunger positioned at least partially within the body, and a biasing member configured to bias the cutting member to an initial position whereby the cutting member is positioned fully within the body, wherein the plunger is slidable into the proximal end of the body, causing the cutting member to extend from the distal end of the body.

A knife having a first body part and a second body part cooperating with one another to allow a blade to be secured thereto, the body parts cooperate with one another such that sliding movement of the first body part relative to the second body part can occur, and a latch arrangement whereby the body parts can be latched against relative sliding movement from a first position towards a second position, the latch arrangement having a resilient member carried by the first body part and cooperable with the second body part to latch the body parts against sliding movement towards the second position, and an opening provided in the second body part through which a tool can be inserted to depress the resilient member and allow such sliding movement to occur.

Devices, systems, and techniques are described for creating pockets in tissue for accepting implantable medical devices. For example, a surgical tool includes a shaft defining a proximal end, a distal end, and a longitudinal axis, a handle coupled to the proximal end of the shaft, and one or more blades configured to move between a retracted configuration and a deployed configuration, wherein the one or more blades extend, in the deployed configuration, substantially perpendicular to the longitudinal axis at the distal end of the shaft. The one or more blades may be configured to separate tissue in the deployed configuration.

An ancillary system for surgery is provided. The ancillary system includes a trocar, a scalpel device and an exhaust device. The scalpel device includes a blade portion and a connecting arm. The exhaust device encapsulates at least a portion of the connecting arm of the scalpel device. The exhaust device is detachable from the scalpel device, and is configured to remove smoke, body fluids or biological tissues generated during a surgery to effectively improve the surgical process.

A robotic surgical instrument includes a housing having a shaft extending therefrom configured to receive a first end effector including jaw members moveable between a fully open position wherein the jaw members are spaced a maximum distance relative to one another and a closed position wherein a closure pressure between the jaw members is within a predetermined range. A drive rod actuates the first end effector upon translation thereof. The housing includes a spring compression assembly having proximal and distal hubs with the compression spring disposed therebetween. A jaw drive input rotates a drive gear to translate the distal hub relative to the proximal hub to compress the compression spring and actuate the end effector. Once the jaw members are fully open, the jaw drive input rotates a preset number of degrees to compress the compression spring and approximate the jaw members to a closure pressure within the predetermined range.

A safety cutting device includes a slidable insert that moves longitudinally within a cavity of a housing. The slidable insert has a cutting blade attached and moves within the housing from a safe position in which the blade is covered to an exposed position for cutting. The safety device has a release button positioned near an anterior end of the housing. A biasing member automatically retracts the blade when the release button is activated.

A scalpel handle includes a body defining a first end and a channel therein and an insert defining a blade holder disposed at a first end thereof and positionable within the channel of the body with the blade holder extending outwardly away from the first end of the body. A shield is coupled with the body such that the blade holder is positionable within the shield, and a removal wedge is defined on the body, fixed with respect to the shield, and disposed in a substantially fixed lateral position at least partially aligned with a portion of the blade holder.

Systems and methods for treating cellulite including an apparatus that applies or a method involving separating septa to eliminate or reduce the appearance of cellulite. In one approach, an interventional tool is placed between tissue layers to engage and treat septa connecting tissue layers between which fat deposits are contained.

Disclosed is a dilating incision device, which relates to a surgical tool and includes an outer shell, a dilating element and an incision assembly. The dilating element that is arranged at one end of the outer shell and communicated with the inside of the outer shell is used to drill into and expand a stenosis segment of the pancreatic or biliary duct or a puncture path between lumens of the digestive tract. A sliding groove is formed in a side wall of the outer shell, by which the inner cavity of the outer shell is communicated with the outside. The incision assembly includes an incision knife arranged in the outer shell and a sliding handle housing the outer shell. An intercommunicating hole is formed in one end of the dilating element, by which the inner cavity of the dilating element is communicated. with the outside.

Diathermy tonsillectomy suction dissector apparatus has a body having a proximal handle, a distal curved tip and a diathermy cutting blade member slidably retained within the body to selectively extend from the tip. The diathermy cutting blade member comprises a flexible metallic blade comprising a proximal electrical connector socket and a hand operable electrically insulative position locking mechanism attached to the blade. The locking mechanism is hand operable via apertures and interlocks therewith to position the diathermy cutting blade member between retracted and extended positions and to lock the diathermy cutting blade member at the extended position.
