Bone plate (1) with a lower surface (2), an upper surface (3), a maximum thickness measured between the lower and upper surfaces a left lateral surface (4), a right lateral surface (5), a longitudinal axis (6) and a plurality of plate holes (7) miming from the lower surface to the upper surface, the bone plate further having a slot (8) in the lower surface extending from the left lateral surface to the right lateral surface having a width measured in a plane parallel to the longitudinal axis and a central plane (16) between the lateral surfaces, wherein (i) the hollow space defined by the slot extends in the form of a straight cylinder from the left lateral surface to the right lateral surface and (ii) the slot comprises an undercut feature (9) limiting the opening of the slot when the bone plate is bent longitudinally in a direction aimed at widening the slot.

A device, system and method for delivery of an implant having an adjustable length. The device is for inserting an implant at an appropriate tissue depth according to a depth finding placeholder, wherein the implant is suitable for insertion to a subject, the device comprising a cannula for receiving the depth finding placeholder and an adjustable depth of insertion element, wherein the adjustable depth of insertion element is adjusted to determine the appropriate tissue depth. The depth finding placeholder may include but is not limited to a wire, such as a K-wire for example. The cannula preferably comprises an opening of sufficient diameter to permit insertion of the depth finding placeholder. The cannula optionally comprises depth indicators, for example by being optionally marked with depth indicator markings. The device preferably comprises a transparent window, or optionally may comprise, additionally or alternatively, an open aperture and/or a viewing screen, to enable the depth indicators to be viewed.

A medical instrument, for example an impact instrument, and a method for producing a medical instrument. The medical instrument includes a proximal end and a distal end. A handle and a striking face facing in a proximal direction are arranged or formed on the proximal end. A tool instrument is arranged or formed on the distal end. An instrument shaft of the instrument extends from the proximal end to the tool element. The handle is configured in the form of a hollow handle.

An ultrasonic surgical tool system with a tip capable of simultaneously vibrating in plural modes. The system includes a console capable of supplying a drive signal to the tip that includes plural components. Each component has a frequency characteristic that is based in part on the equivalent of current through the mechanical components of the tip. The frequency components are different from each other. Based on the application of drive signal the tip undergoes non-linear vibrations.

According to an embodiment, an embolic apparatus includes: a main body portion extending in a longitudinal direction; a plurality of first frame portions foldably connected to the main body portion; a plurality of second frame portions foldably connected to an end opposite to the other end of the main body portion connected to the plurality of first frame portions; and a blocking film portion connecting the plurality of first frame portions and covering the first frame portion, wherein the first frame portion and the second frame portion extend in directions away from each other.

An implantable closure device for sealing an opening, such as a puncture, through a biologic tissue membrane, such as the meninges, against leakage of biological fluid. The closure device includes a fluid sealing plug configured to be positioned at least partially within the opening through the biologic tissue membrane. A retainer is configured to secure the fluid sealing plug at least partially within the opening. The retainer includes a proximal retainer portion configured to be disposed proximally on the biologic tissue membrane, a distal retainer portion configured to be disposed distally on the biologic tissue membrane, and a central retainer portion connecting the proximal retainer portion and the distal retainer portion. The central retainer portion is configured to extend through the opening. The fluid sealing plug is coupled to the central retainer portion.

A surgical instrument and a linear surgical stapler are provided. The instrument includes: a suturing mechanism including an anvil assembly and a mounting part for mounting a staple cartridge assembly, in which the staple cartridge assembly includes a staple cartridge for accommodating staples, and the anvil assembly includes an anvil matched with the staple cartridge; a staple pushing assembly, configured to push the staples so that the staples are sequentially fired; a transmission assembly, configured for driving the staple cartridge assembly to move relative to the anvil assembly and driving the staple pushing assembly to move to push the staples; and a drive assembly, connected to the transmission assembly and configured for driving the transmission assembly to move.

This invention relates to a skeletal support member (1) and more specifically, but not exclusively, to a skeletal support member (1) for use in spinal or intramedullary surgery. In accordance with the invention there is provided a skeletal support member (1) comprising an elongate body with integrally formed inner (2) and outer (3) portions, at least one mechanical attribute of the inner portion (2) differing from a corresponding mechanical attribute of the outer portion (3), and the inner portion (2) being shaped and sized such that a corresponding mechanical attribute of the body varies longitudinally. It is envisaged that the invention will provide a skeletal support member (1) which has varying mechanical properties along the length thereof in at least one direction which may be specifically tailored to allow specific movement and apply corrective forces and moments which are bespoke to a patient.

A vibration transmission member includes: a main body portion configured to transmit ultrasound vibration; a treatment portion that is provided at a distal end of the main body portion, the treatment portion being configured to apply ultrasound vibration to a living tissue; a coating portion that is made of an electrically insulating material containing a first resin, the coating portion being configured to cover a part of a surface of the treatment portion; and a mold portion that is made of an electrically insulating material containing a second resin different from the first resin, and that is fused to at least a part of the coating portion.
