The invention discloses a locally abandoned agent-tube cylinder, which comprises the following parts: running hollow injection cylinder, handle pivoted at back end of the injection cylinder, push rod in the injection cylinder and handle, wherein the injection cylinder, handle and push rod are stainless steel material; the front end of the injection cylinder is a spiral joint end with a perspective cylinder which is made of transparent or perspective material; one needle joint and through-hole are set at the front end of the perspective cylinder; the needle joint connects a double-head needle which contains needle seat to connect the needle and injection rod throughout the needle seat. The inveniton can observe liquid condition in the cylinder sufficiently, which can judge the exertion and optimum stopping point precisely.

A hinged tool includes a first member; a second member pivotally connected to the first member at a pivot; and an optical fiber. The optical fiber is fixed to the first member at a load application region and fixed to at least one of the pivot and the second member at a location such that the optical fiber bends when the first member and the second member are pivoted with respect to one another. A method of using a hinged tool includes measuring fiber strain in an optical fiber fixed to the hinged tool, and determining at least one of tool strain applied to the hinged tool and a degree of pivoting of the hinged tool using the fiber strain.

Devices and related methods for the dynamic correction of spinal deformities are disclosed. The devices and methods are particularly useful for correcting an abnormal curvature of the spine. In one exemplary embodiment, a method for correcting deformity via a spinal implant that can include a polymer between or attached to a top and bottom plate, which can exist in a wedge-shaped configuration in order to apply asymmetric forces to the spinal column, is provided. The implant may be inserted between adjacent vertebrae comprising part of the abnormal curvature, thereby restoring the normal curvature of a spine.

The invention discloses a split type thrust tool, and aims to provide the split type thrust tool which enables each product to be stressed uniformly and consistently. The split type thrust tool comprises a rack, a placing table, a conveying belt, a sliding plate and a plurality of split type air cylinders, the placing table is horizontally arranged at the inner bottom of the rack in the left-right direction, a conveying groove penetrating through the left side face and the right side face is formed in the top face of the placing table, the right end of the conveying belt penetrates through the left side wall of the rack, then is arranged on the left side of the placing table and corresponds to the conveying groove; the sliding plate is connected with the rack above the placing table, the split type air cylinders are evenly distributed on the sliding plate from left to right, thrust assemblies are arranged on the split type air cylinders, a plurality of containing discs corresponding to the split type air cylinders in a one-to-one mode are arranged in the conveying groove, the containing discs are connected with the front inner side face of the conveying groove in an up-down rotating mode, and the thrust assemblies are arranged over the containing discs. The split type thrust tool has the beneficial effects that each product is uniformly and consistently stressed, and unqualified products are automatically recycled; and various unqualified products can be accurately detected.

The invention provides a mechanized feeding device suitable for the production of multi-standard pipes, which relates to the technical field of mechanized feeding devices, to solve the problem that the original feeding device is not equipped with a structural device with a variety of convenient and adjustable gripping conveying, which causes the feeding device It not only reduces the adjustable diversification of the conveying function of the feeding device, but also cannot meet the needs of the mechanized feeding device for various multi-standard pipes in production, and cannot adjust the front and rear telescopic angles according to the actual pipe specifications, nor can it be completed. The diversified grasping conveying of the feeding device not only reduces the working efficiency of the feeding device, but also reduces the practicality of the feeding device, including the support plate; the inner side of the support plate is respectively connected to the semi-arc-shaped chassis plate . In the present invention, since the moving rod and the connecting claws belong to a unified structure with the function of adjusting movement, the connecting claws move along the crossing movement of the moving rods.

The invention relates to the technical field of material conveying, in particular to a feeding structure and a loading and unloading device. A feeding structure, comprising: a frame body with at least one inclined conveying channel, a first end of the conveying channel with a lower horizontal position is formed with a discharge port in a conveying direction perpendicular to the conveying channel; a push assembly , located on the opposite side of the frame body to the discharge port, used to pass the material moving to the first end of the conveying passage through the discharge port along the conveying direction perpendicular to the conveying passage Partially launched. The invention provides a feeding structure and a loading and unloading device which are convenient for a manipulator to grab materials and have high processing efficiency.

The invention provides a performance testing apparatus of a two-way rocking mechanism. The performance testing apparatus of the two-way rocking mechanism comprises a supporting frame, a force application device, a driving system and a heating lamp. The integral structure of the rocking testing system is designed to have the rotational degrees of freedom in a direction and the force application structure is located inside the rocking mechanism and can swing around the axis coaxial to a rotating shaft of the rocking mechanism. The two-way rocking testing of the rocking mechanism is available by manually adjusting directions. The rocking of the rocking mechanism is driven by a stepper motor. The rotation shaft of the rocking mechanism is heated by a quartz infrared shortwave radiator. The performance testing apparatus of two-way rocking mechanism is multiple in functions, compact in structure, high in accuracy, good in strength, easy to operate, safe and reliable.

In the emulsification method of Yunnan Baiyao provided by the present invention, the effective components of Yunnan Baiyao are extracted, combined with borneol and emulsifier, and beeswax to prepare uniformly dispersed Yunnan Baiyao tablets. Maintain no deformation. The pressure dressing for hemostasis that can promote wound healing prepared by using the Yunnan Baiyao hemostasis tablet can stop bleeding immediately while maintaining the good efficacy of Yunnan Baiyao and promote wound healing. Moreover, the microporous structure on Yunnan Baiyao hemostatic tablets can absorb and transfer wound exudate and blood in time, which is beneficial to wound recovery. In addition, the dressing provided by the present application can be applied to different wounds through changes in shape and size, and has a wide range of applications.

A device to be used by an operator which may grasp objects in a sterile or non-sterile field, and may facilitate the precise placement and passage of a needle or pin into tissues while using X-ray guidance. The device provides a secure hold while keeping the hands remote from the radiation field, and by permitting non-obstructed viewing of the held instrument and tissues. A radiolucent hammer may be used to help drive a needle into firm tissues without obscuring visualization.
