Description

Microscopic endoscope system under joint synovial cavity balloon expansion device

Technical Field

The utility model relates to a joint endoscope technical field, especially a micro-endoscope system under joint synovial cavity sacculus expanding unit.

Background

At present, when arthroscopy is used for joint surgery, at least three holes are needed to be drilled on the joint of a patient, one hole is used for inserting an endoscope, the other hole is used for inserting a surgical instrument, and the other hole is used for injecting water into the joint to expand a synovial cavity and provide an operation visual field for a surgeon, so that the pain of the patient is increased, the operation visual field is narrow and the operation difficulty is high during operation. Arthroscopic surgery is generally long, and the fluid that expands the joint inevitably extravasates, causing a series of complications, and if the joint fluid extravasates seriously, causing the surgery to fail, etc.

The prior utility model with the patent number of arthroscopic surgical instrument being CN201420569352.4 discloses a micro-endoscope system, but the utility model discovers that the prior channel sheath can not be matched with the endoscope in the using process, and the spherical air bag extrudes the incision tissue part back and forth, which is easy to cause discomfort and infection of patients, the prior channel sheath is a hard metal sheath tube, the length of the prior channel sheath is far more than the thickness of skin soft tissue at the incision of the arthroscope, the prior channel sheath is easy to drop in the operation, the moving space in the relatively narrow joint clearance such as elbow joint is extremely limited, so the use is inconvenient, many surgeons often abandon the channel sheath after establishing the channel in the arthroscopic surgery, the arthroscopic instrument directly and repeatedly enters and exits the incision, the wound at the incision is easy to increase, and when the patient changes the body position, all layers of soft tissue of the arthroscope incision displace along with the channel sheath, the channel is deformed, an operator often needs to reestablish an arthroscope channel, the operation efficiency is greatly reduced, local wounds are increased, and in addition, a series of complications such as edema, periosteum syndrome and the like can be caused when physiological saline filled in the joint cavity leaks into subcutaneous gaps.
