The proposed device Single Use Hemoclip is a sterile, single-use endoscopic clipping device, intended to be used for endoscopic marking, hemostasis for mucosal/submucosal defects in digestive tract. It consists of two main components, delivery system and clip assembly. And it is offered in different dimensions.

The device is intended to use in urologic endoscopic procedures to facilitate the passage of endoscopes.

The Single Use Ureteral Access Sheath is a single use sterile device, provides ureteral dilation and a continuous working channel for the introduction of endoscopes and instruments during ureteral access procedures. The Ureteral Access Sheath is comprised of five components: outer sheath base, outer sheath, dilator tube, locking clip and joint. The outer surface of the sheath has a hydrophilic coating. When activated, the hydrophilic feature allows for easier insertion and removal of the sheath. The sheath is offered in three French sizes: 10Fr, 12Fr and 14Fr, and range in effective length of sheath from 10.0cm (shortest) to 55cm (longest). The device is packaged in a peel-open pouch with a two-year shelf life.

The device is used for endoscopic injection into gastrointestinal mucosa, or to endoscopically introduce a sclerosing agent into selected sites to control actual or potential bleeding lesions in the digestive system.

The Sclerotherapy Needle device consists of Luer connector, handle, sheath, infusion tube, fixed button connection tube and needle. EO sterilization and use for single use only. The Sclerotherapy Needle device is designed to pass through the channel of endoscope to mark the lesions of the digestive tract and use it for injection. Compatibility with endoscopes, working lengths are 1200mm,1800mm, 2000mm, 2300mm, and the minimum working channel is ф 2.8 mm.

Single Use Grasping Forceps are indicated for use in gastrointestinal tract of the patient to grasp, clip, drag, and remove tissue or foreign particle during endoscopic procedures.

The proposed device Single Use Grasping Forceps is a sterile, single-use device, designed to pass through a 2.0mm and 2.8mm or greater working channel of an endoscope. The main components of Single Use Grasping Forceps are jaws, spring sheath and handle. This device can be used to grasping tissue and/or retrieve foreign bodies, and excised tissue through jaws open and close. The Single Use Grasping Forceps has three models, the differences of these models are type of jaws, OD of the device and working length.

Disposable Valve Sets includes either one air/water and suction valve or one air/water, suction and biopsy valve. Disposable Air/Water Valve: This device intended to be fitted to an endoscope air/water channel to enable the operator to control inflow of medical gases and water, whilst preventing backflow during a GI Endoscopic procedure. Disposable Suction Valve: The device intended to be fitted to an endoscope suction channel to enable the operator to control suction whilst preventing inflow of air during a GI Endoscopic procedure. Disposable Biopsy Valve: This device is intended to be fitted to an endoscope biopsy port to enable access for/exchange of endoscopic devices while maintaining insufflation and minimizing leakage of bio material during an endoscopic procedure.

Disposable Valve Sets includes either one air/water and suction valve or one air/water, suction and biopsy valve. So we divided into two models for these devices. One suction valve, air/water valve and biopsy valve means model B, one suction valve and air/water valve means model A. These devices are supplied sterile. These valves easily incorporate into infection prevention policies as a single use item, and these valves are suitable for Olympus 140/160/190/240/260 series endoscopes.

The Disposable Biopsy Valve is used to cover the biopsy/suction channel of Olympus® and Fujinon® or Pentax® gastrointestinal endoscopes. It provides access for endoscopic device passage and exchange, helps maintain sufflation, minimizes leakage of biomaterial from the biopsy port throughout the endoscopic procedure, and provides access for irrigation.

The Disposable Biopsy Valve is provided non-sterile, and is composed of a cylindrical base and a connected cap. The Disposable Biopsy Valve provides sealable access via the working channel port of an endoscope for surgical instruments. The valve consists of an attached cap and valve body with a circular opening. The cap is pre-perforated, and ensures instrument access and removal is tight and leak-free. The valve is designed with a hollow body with a distal end that releasably attaches to the inlet port of the working channel. The valve body provides a flexible diaphragm seal that separates the body into a proximal chamber and distal chamber. The distal chamber secures onto the endoscope, while the proximal chamber secures the cap. Instruments are inserted through the cap and chambers, through the diaphragm seal, and into the endoscope. The diaphragm seal is configured such that a seal is formed due to deformation of the elastomer around an instrument when it is inserted through the opening, preventing fluids from passing through the biopsy valve. The cap serves two primary functions. One function of the cap is to provide an additional seal around surgical instruments to prevent leakage. The second function is to allow modification of pressure during insufflation by opening the cap, allowing gasses to flow from the endoscope, and out of the biopsy valve.
