The present disclosure provides a multipurpose endoscopic surgical instrument. The instrument adopts a technical feature in which an interchangeable tool and a tool holder are connected to each other by inserting the mounting key into the opening mounting groove, and adopts a technical feature that the driving member includes an inserting block at the front part. It realizes the technical solution that by moving the inserting block to insert into the interchangeable tool to prevent the mounting key from moving out of the opening of the mounting groove, the interchangeable tool can be mounted on the tool holder. It realizes the technical solution that by moving the inserting block to exit the interchangeable tool, the interchangeable tool can be moved out of the tool holder.

In an example, there is disclosed a computing apparatus, having: a data interface to communicatively couple to a storage pool having a plurality of disks; a virtual machine manager including a processor; and a storage coprocessor (SCP) to: create a read queue and write queue for the disks in the storage pool; receive an input/output (IO) operation from a virtual machine, the IO operation directed to a storage address located on a disk in the storage pool; and add the IO operation to the queue for the disk.

Merged input/output operations from a plurality of virtual machines

An interface of the needle of a medical syringe and realizes that a conical fitting and a conical inclined surface of a syringe barrel and a conical lip and a conical hole of the needle form an interface of the needle; when the conical hole of the needle is plugged onto the conical fitting of the syringe barrel, the needle is fixed onto the conical fitting of the syringe barrel to achieve the purpose of preventing a needle tip from swinging when the needle pierces a muscle or a blood vessel of a human body, so as to avoid misoperation; and after the medical syringe is used, the conical lip of the needle distal away from the needle tip only needs to be pinched flat, the needle can then be separated from the conical fitting of the syringe barrel of the medical syringe.

A femoral head support device, in particular a mineralized collagen-based femoral head support device applicable to the treatment of early osteonecrosis of femoral head. The device is made from a dense, homogeneous organic/inorganic composite, wherein the organic phase includes collagen and inorganic phase includes nano calcium phosphate salt, and the device is of a cylinder having an upright through hole and also has a support strength of up to 4000-6000N. By implementing a method for manufacturing such mineralized collagen-based femoral head support device, the mineralized collagen-based femoral head support device with mechanical properties equivalent to human cortical bone can be manufactured; and the mineralized collagen-based femoral head support device can meet the demand for clinical treatment of early osteonecrosis of femoral head to avoid the continuous collapse of necrotic femoral head.

The present invention disclosed a surgical staple () and staple pocket () for forming kidney-shaped staple therefor, with the staple pocket () being recessed inward on the tissue contacting surface of the staple anvil (), and with M-shaped staple () being used, wherein the degree of projection of the middle portion of the back span () of the M-shaped staple () arranged at the inner circle or arranged at a proximal side of a cutter slot () is larger than that of the back span () of the M-shaped staple () arranged at the outer circle or arranged at a distal side of the cutter slot (), so that when the staple () of the same height are adapted to staple tissues to be stapled of different thickness, staple driver () bends the M-shaped staple () on the staple pocket () to form kidney-shaped staple () so as to achieve the operational effect of being able to seal the stapled tissue, to stop bleeding and to heal the tissue therearound.

An endoscopic surgical cutting stapler with a chain articulation is provided, in which a joint is implemented by a chain articulation, teeth are provided at two ends of a chain plate of the chain articulation, and teeth of adjacent chain plates in the same row are engaged. Through mesh transmission of engaged teeth of the adjacent chain plates in the same row, an angle of a most proximal chain plate of the chain articulation is gradually multiplied at several stages and transmitted to an end effector. The end effector can rotate for 90&#xb0; with small drive motion of the operating mechanism, thereby achieving precise placement of the chain articulation after rotation. The end effector can be precisely aligned with a part to be cut and stapled, and a radius of curvature of the chain articulation can be significantly increased.
