11497511 · 2022-11-15 · ·

An orthopedic surgical instrument comprising: a customized patient-specific acetabular reaming guide comprising an at least partially circular body, having an inner surface defining a slot sized to receive an acetabular reamer head, and further having a top surface defining a contact element; at least one support element configured for supporting the at least partially circular body on a patient-specific anatomy of a coxal bone; and further comprising at least one acetabular reamer head comprising a bone milling portion configured for insertion in the slot of the acetabular reaming guide; a connecting element configured for removable attachment to a reamer's shank for operation of the at least one acetabular reamer head; wherein the orthopedic surgical instrument further comprises an abutment element attached to a top portion at least one acetabular reamer head and configured to limit a milling depth of the bone milling portion, by resting on the contact element of the acetabular reaming guide.

ASPIRATION CATHETER INCLUDING MECHANICAL CUTTER
20220354528 · 2022-11-10 ·

In some examples, a catheter includes an elongated body defining an inner lumen and comprising an expandable member disposed at a distal portion of the elongated body, and a rotatable cutting tool located within an inner lumen of the elongated body, the rotatable cutting tool configured to segment a thrombus into smaller pieces while an aspiration force pulls the thrombus proximally into the inner lumen. In some examples, the catheter further comprises an intermediate structure oriented radially between the rotatable cutting tool and an interior surface of the elongated body, the intermediate structure configured to prevent the cutting tool from contacting the interior surface of the elongated body. In some examples, a stopper is configured to limit movement of the cutting tool distally past a distal end of the expandable member.

20230044200 · 2023-02-09 ·

An end effector assembly of a forceps includes a first jaw with a tissue sealing surface and an electrode on the sealing surface, and a second jaw with a tissue sealing surface and an electrode on the sealing surface. The first jaw and the second jaw move between an open position and a closed position. The sealing surface of at least one of the first jaw and the second jaw has a rigid medial section and flexible lateral sections.

Implant with Hole Having Porous Structure For Soft Tissue Fixation

Disclosed herein are an implant with an attachment feature and a method for attaching to the same. The implant may include a cavity with a porous layer disposed within a non-porous layer wherein the non-porous layer defines a chamber. The chamber may receive and confine liquefiable material and direct liquefiable material to permeate through the porous layer. A method of attaching a device to the implant may include liquefying a liquefiable portion of the device and allowing the liquefied material to interdigitate with the second layer and then solidify to prevent pullout.

Gap control via overmold teeth and hard stops

A forceps includes an end effector assembly having a stop and a plurality of overmold teeth within at least one jaw member. One (or both) of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a stop molded within an insulative housing, and an insulator plate with the overmold teeth formed from plastic. The overmold teeth extend through openings within a sealing plate and protrude past the tissue sealing surface of the sealing plate. The stop primarily controls the gap distance between opposing jaw members by bearing most of an applied load and the overmold teeth assist in controlling the gap distance by bearing the remaining applied load.

RELOAD ASSEMBLY WITH KNIFE CARRIER LOCKOUT

A surgical stapling device includes a reload assembly that includes a locking member to retain a knife carrier of the reload assembly in a retracted position after the stapling device is fired. The locking member may be supported on an inner housing portion of the shell housing or on a staple pusher assembly of the reload assembly.

Osteotomy assistance kit
11490900 · 2022-11-08 ·

An osteotomy assistance kit includes a bone treatment assistance device and an attaching position confirmation device. The attaching position confirmation device includes a feature point indication rod to be applied via a tip portion to a feature point of the bone, a rod support unit that removably supports the feature point indication rod such that the tip portion is indicating the feature point of the bone, and a second support member that movably supports the rod support unit and indicates one of scales on the rod support unit. The bone treatment assistance device includes cutting slits, and first guide holes that guides first rods set to a predetermined positional relation. The second support member of the attaching position confirmation device is attached to the protrusion of the bone treatment assistance device.

Treatment tool
