The use of disposable live sampling forceps

Sampling forceps enter the human body through the monitoring function of endoscopic forceps, the forceps head is aimed at the lesion, open the jaws and press the handle slider to close the collected tissue, close the jaws, pull the handle slider to pull back the outer tube, and then remove it. Sampling forceps is enough, let's learn together the use of disposable live sampling forceps!

Scope of application: sampling forceps are suitable for endoscopic sampling of gastric and duodenal biopsies.

Disposable live sampling forceps product features:

1, the product has been sterilized, no sterilization before use.

2, sampling forceps are made of medical stainless steel.

3, using laser welding, the connecting rod is reliable.

4, pure factory production, after strict inspection and delivery to ensure product quality.

5、Configured with various specifications.

The use of disposable live sampling forceps:

1, open the product packaging, remove the disposable biological sampling forceps.

2、Extend the sampling forceps through the endoscope to the abdominal surgical site, and move the handle to the root of the handle. Put the disposable biological sample forceps all into the endoscope and gradually remove the lesion tissue removed by the forceps according to the surgical needs.

3, remove the lesion tissue removed by forceps, and then remove the disposable biopsy forceps out of the body.

The types of sample forceps are divided into standard type, side opening type, front end needle type, round cup shape, tooth cup shape, etc. The connection is mainly made by laser welding. Laser welding can be achieved by continuous or pulsed laser beams. The laser irradiation heats the surface to be processed and the heat from the surface diffuses to the inside by heat conduction. By controlling the laser parameters such as width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted and a specific melt pool is formed. The energy conversion mechanism is accomplished by a "small hole" structure. When the screw of the sampling clamp is broken, it cannot be repaired by conventional welding. In recent years, most of the sampling pliers use rigid four-link mechanism, so that the use of sampling pliers more convenient.

The key to using sampling pliers is to master the strength of the hand, most people are used to ring finger, middle finger, index finger and thumb, can also be used with sampling pliers. Sampling pliers require a moderate amount of strength in the use of the process. The switch should not be too hard. This not only does not work well to take the clamp on the lesion tissue, but also easily damage the sampling clamp.

Sampling forceps tensile strength of 10kg, clear upper and lower dead points, in line with the doctor's use habits; produced in a sterile factory, strict sterility check at the factory.

Disposable in vivo sampling forceps should be studied at least from the following aspects.

1, sampling forceps product performance research

Product performance research data and product technical requirements research and preparation instructions, including the basis for determining the effectiveness, safety indicators and other indicators related to quality control, the standards or methods used, the rationale and theoretical basis for their use. Applied to medical devices, should provide material applicability of the relevant research data.

2, sampling clamp biocompatibility evaluation study

At the time of product registration, according to the nature of the materials used in the product and its contact with the human body, medical device evaluation in accordance with the standards of "Biological Evaluation: Risk Assessment and Detection" management process ". At least cytotoxicity, intradermal reactions and sensitization biological evaluation tests.

3, sampling clamp sterilization / disinfection process research

(1) Sterilization process (method and parameters) and sterility assurance level should be specified and sterilization confirmation report should be provided. And provide residual toxicity study report.

(2) If the sterilization method is prone to produce residues, such as ethylene oxide sterilization, the residues and treatment methods should be clarified and research information should be provided.
