The devices and methods shown provide for the minimization of extravasation during arthroscopic surgery. The anti-extravasation sheath allows a surgeon to drain excess fluids from the soft tissue surrounding the surgical field during arthroscopic surgical procedures.

An arthroscopic inflow and outflow sheath providing an improved inflow and outflow system reducing the diameter of a continuous flow system while providing fluid management during arthroscopy. The improved arthroscopic inflow and outflow sheath comprises an elongated atraumatic sheath having an inner surface, outer surface, proximal end, and distal end. The atraumatic sheath further comprises plurality of ribs or webs extending from the inner surface of the sheath and designed to contact an outer surface of the arthroscope thereby creating outer lumens facilitating the inflow and outflow of fluid to a surgical site.

A removable, resilient atraumatic sheath for arthroscopic instruments. The sheath covers sharp edges on the arthroscopic instrument, particularly the distal tip of the rigid cannula, and thereby protects tissue and objects near a surgical site from accidental trauma. The sheath may be provided in the form of an inflow/outflow sheath that allows a surgeon to irrigate and drain a surgical field without the use of a separate irrigation instrument.

The invention discloses an endoscope for a whole-course visible abortion operation, which comprises a computer (14), a CCD camera (15) and an endoscope component (16), wherein a photosensitive device of the CCD camera (15) is opposite to an eye lens of the endoscope component (16), and a signal output end of the CCD camera (15) is connected with a signal input end of the computer (14) through a data wire (17). The endoscope is characterized in that a light source of the endoscope component (16) consists of a lighting source and an infrared imaging light source (10) capable of generating infrared light of which the wavelength is more than 700 nanometers. The endoscope has a simple structure, is easy to implement, is favorable for improving the operation efficiency and the rate of success, improves the safety of the operation, and solves the difficulty of an unclear visual field during a hemorrhagic operation.

The invention relates to a facet joint retractor, which is formed by hinging two tong arms a hinge pin. The facet joint retractor is characterized in that one sides of front ends of the two tong arms are respectively provided with a cantilever; each cantilever is provided with a kirschner wire hole; inner sides of rear parts of the two tong arms are respectively provided with a spring piece; free ends of the two spring pieces are mutually engaged; the tail end of one of two tong arms is connected with a trapezoidal lock by a lock pin. When the facet joint retractor provided by the invention is used, firstly, two kirschner wires respectively penetrate skeletons which correspond to a facet joint, so that the two kirschner wires are parallel. Then, the two kirschner wires are respectively led into the kirschner wire holes arranged in the cantilevers to oppositely squeeze the rear parts of the two tong arms, so that the two cantilevers are mutually separated, and therefore, the facet joint is retracted to form a joint space, and the joint retracted state is locked and kept by the trapezoidal lock. The facet joint retractor provided by the invention has the advantages that the structure is simple, manufacturing is convenient, the use is convenient, a retracting effect is stable, an operating field is clear, operation techniques are convenient, and the operation time is reduced.
