Handheld Elongate Medical Device Advancer and Related Systems, Devices and Methods
A handheld advancer is provided for advancing an elongate device through a pathway defined in an advancer body and include a rotatable manual control partially embedded in the body to receive a user-exerted manual control movement from a thumb of a single hand that can hold and control the advancer and advancement. The advancer can include a manual drive arranged to convert torque applied by the thumb for a rotation arc distance into a translation drive force applied for translating the elongate device an advancement distance scaled at force factor and distance factor. The distance factor can be one or greater than one and translate the elongate device an amplified advancement distance compared with manual input. The advancer can include a nip having a pair of rollers extending into the pathway providing constant control and amplified translation via concave compressible surfaces forming continuous contact regions with the elongate device.
Surgical Tool and Method
A surgical tool and method for engaging and manipulating a bone includes a tool body having a main body axis, a threaded end, and a handling end, the threaded end having threads and a tool stop. The handling end is positioned to allow a user to grasp, manipulate, and rotate the tool body around the main body axis. The threads are positioned to allow the surgical tool to bore into and engage the bone when the tool body is rotated in a boring direction around the main body axis, the threads allowing for tightening engagement with the bone as the tool body is rotated in the boring direction around the main body axis. The tool stop is positioned to prevent the tool from being further rotated around the main body axis to prevent further boring into the bone when the tool stop contacts the bone.
EVERSION TOOL AND SIZE GUIDE FOR PERFORMING ARTERIAL MICROVASCULAR ANASTOMOSIS
An everter device includes a handle and at least one eversion tip. The handle has a first end and a second and each of the at least one eversion tip is coupled to a respective end of the handle. Additionally, the at least one eversion tip has a respective distal end, a respective proximal end, and a respective eversion surface. A sizing device includes a handle and at least one sizing guide. The handle has a first end and a second end. Each of the at least one sizing guide is coupled to a respective end of the handle. Additionally, the at least one sizing guide has a plurality of sizing apertures and associated sizing indicators. The everter device and the sizing device may be provided together as a kit.
Method of placing a bone implant in an operative position with respect to a bone part
The combination of: a) a bone implant having a body with a first portion that overlies an outer bone surface and first and second projections; and b) a bone implant handling instrument comprising: a guide assembly; and an implant advancing assembly. With a part of the bone implant handling instrument bearing against at least one bone part, the bone implant can be guided by the instrument in substantially a straight line in a first direction, while being maintained in substantially a same orientation with respect to the straight line, between a starting position and one operative position. The implant advancing assembly has at least one part that is movable against the bone implant to advance it into the operative position wherein the first and second projections are advanced into one or more bone parts and the first portion of the body overlies an outer bone surface. A method of placing the bone implant is also provided.
FLUID FLOW METAL SLEEVE
A fluid flow metal sleeve includes a sleeve main body and an elongation portion, which are of a hollow structure as a whole. The sleeve main body is connected to the elongation portion in a threaded manner, and a terminal end of the sleeve main body is connected to an ultrasound scalpel handle and enables an ultrasound scalpel to pass therethrough. The fluid flow metal sleeve can control the direction of fluid flow during incision with the ultrasound scalpel so as to achieve the lubricating and cooling effects on a scalpel head. In addition, due to the use of a metal structure, a user can extend an original holding part from an outer portion of the ultrasound scalpel handle to an outer wall of the metal sleeve as required. The fluid flow metal sleeve also has an adjustable telescopic function so as to be adapted to different application scenarios, and limits the length of extension of the scalpel head so as to limit the depth during incision to improve the safety of surgery.
Dual lever to reduce force to fire in circular surgical stapler
An apparatus includes a body assembly with a handle and a shaft portion, an end effector with a staple deck fixed to the shaft portion, an anvil, and a firing assembly. The end effector further includes a trocar and a staple driver both configured to actuate relative to the staple deck. The staple driver can actuate a distance between an unfired position and a fired position. The trocar can couple with the anvil to define a gap distance. The firing assembly includes a trigger pivotably coupled with the body assembly via a first pivot, a driver actuator configured to actuate the staple driver, and a linkage assembly pivotably coupled with the trigger via a second pivot and the driver actuator. Where the second pivot is proximal relative to the first pivot. The linkage assembly can drive the driver actuator is response to the trigger pivoting about the first pivot.
SYSTEMS AND APPARATUSES FOR MANIPULATING BENDABLE ALLOGRAFTS
A Surgical forceps device comprising a pair of shanks and a clamping jaw portion, the clamping jaw surfaces set at an angle that produces a desired angular position for grasping a bendable osteochondral allograft.
TIBIAL RESECTION GUIDE DEVICE
The present disclosure relates to a guide device for tibial resection comprising a guide jig having a slot for a surgical saw, a first feeler provided for coming into contact with a point of a tibial plateau and a second feeler provided for coming into contact with a point of a tibial plateau. The first feeler and the second feeler can be rotated with respect to one another and to the guide jig around the same rotation axis and the first feeler can be translated with respect to the second feeler and to the guide jig along a first sliding direction contained within a first sliding plane. The second feeler can be translated with respect to the first feeler and with respect to the guide jig along a second sliding direction contained in a second sliding plane parallel to the first sliding plane.
Drill guide with adjustable stop
Drill guides and related methods are disclosed herein, e.g., for use in surgical procedures. In some embodiments, a drill guide can include an adjustment mechanism that permits one-handed adjustment of the guide depth and does not require that the drill guide be removed from the patient or that the drill be removed from the drill guide when making an adjustment. The adjustment mechanism can include a trigger that moves first and second detents into and out of engagement with a guide stem to allow step-wise adjustment of the guide depth.
TOOL HOLDER FOR MODULAR TOOL
A tool holder for a modular tool may receive a tool element which may be inserted laterally by sliding a dovetailed part of the tool into a slot on the tool holder. A securing pin may be inserted through the body of the tool holder so as to enter the slot, thereby locking the tool element in place. The locking pin is pivotally mounted to one side of a rocker, the rocker being pivotally coupled to the tool holder body so that by cycling the rocker from one position to another, the locking pin is moved back and forth through the body of the tool holder to engage or disengage the tool element. The rocker may be of a resilient material so as to clip into position on the tool holder. Protrusions may resiliently engage corresponding features on the tool holder so as to latch in either or both positions.
