6 results about "Retraction cord" patented technology

This invention relates to the field of medical device technology, disclosing a suture traction device and its application method. The suture traction device is used to pull the suture into the nail body of a full suture anchor assembly. The side wall of the traction box has two holes for passing the traction suture through. The traction cover has a first winding post for winding the traction suture, and the traction base has a second winding post for winding the traction suture. The base is detachably connected to the traction base and has multiple limiting posts for winding the traction suture. The limiting posts pass through the side wall of the traction base and extend into the receiving cavity. Each first winding post has limiting posts on both sides. This invention significantly reduces the frictional resistance between sutures at the pre-placed knot and between the suture and the nail body during suture traction, preventing the pre-placed knot from tightening during traction, allowing the suture to smoothly pass through the nail body, greatly reducing traction resistance, and preventing suture cuts to the surgeon during traction.

An eyewear cleaning device (10) has a storage housing (20) with a housing cover (22) and a side flange (24), the side flange (24) having an aperture (26). The device also includes a cleaning cloth (30) with a stop plug (28) at a proximal end (32) and a retraction cord (34) at a distal end (36). The retraction cord (34) is coiled upon a spool (44) of the storage housing (20), and a retraction mechanism (42) biases the spool (44) to retract the retraction cord (34) so that the cleaning cloth (30) is retracted into the storage housing (20) until the stop plug (28) abuts the aperture (26) in the side flange (24) of the storage housing (20). An enclosure tank (50) holds a cleaning fluid, and a pump mechanism (56) pumps the cleaning fluid from the enclosure tank (50) into the storage housing (20) to moisten the cleaning cloth (30).

This application relates to a full-suture anchor fixation system, belonging to the technical field of medical devices. It includes an inserter and a nail body. The inserter includes a handle, a rotating assembly, and a hollow rod. One section of the hollow rod is inserted into and fixedly connected to the handle. The rotating assembly includes a knob, a stud, and a winding post. The knob is sleeved on the stud and threadedly connected to it. The winding post is positioned above the stud. A left traction suture and a right traction suture pass through the nail body, and the ends of the left and right traction sutures are fixedly connected to at least two connection points on the nail body. The hollow rod has a channel for the traction sutures to pass through. The winding post is movably disposed within the hollow rod and is drivenly connected to the stud. The tip of the inserter has a clamping groove for holding the nail body. This application has the effect of allowing the nail body to smoothly form a bundle during suture preparation.

The application discloses a dental floss cleaning device and method specially used for orthodontic people. The device mainly comprises a dental floss, a dental floss traction line connected with the dental floss and a supporting assembly. In operation, the dental floss traction line is firstly passed through an arch wire of an orthodontic appliance, and then the dental floss is passed through the dental floss traction line; the dental floss is taut and fixed on the supporting assembly by pulling the dental floss traction line, and then the interdental cleaning can be performed. The device can effectively avoid rigid interference with the bracket and the arch wire, and reduce the risk of falling off of the bracket and the arch wire.

This application relates to the field of oral retraction technology, providing a device for adjusting and cutting the length of a retraction line intraorally. The device includes an upper body and a lower body. The lower body has a receiving cavity, and its front end has two parallel thread guide grooves. A tangent groove perpendicular to the thread guide grooves is also provided on the front end of the lower body. One end of the thread guide groove extends to the side of the lower body, and the other end extends to the receiving cavity. A telescopic adjuster with a movement direction perpendicular to the thread guide grooves is provided within the receiving cavity. A thread catcher is elastically mounted on the telescopic adjuster. Both ends of the retraction line pass through the two thread guide grooves and are caught on the telescopic adjuster by the thread catcher. A press-type cutting blade assembly is provided within the upper body. The cutting blade of the press-type cutting blade assembly is movably positioned above the tangent groove and can be inserted into the tangent groove and moved to the bottom to cut the retraction line. This device can adjust the length of the retraction line according to the current cervical circumference of the tooth and can cut it. It is convenient to operate and has good safety.

An eyewear cleaning device has a storage housing with a housing cover and a side flange, the side flange having an aperture. The device also includes a cleaning cloth with a stop plug at a proximal end and a retraction cord at a distal end. The retraction cord is coiled upon a spool of the storage housing, and a retraction mechanism biases the spool to retract the retraction cord so that the cleaning cloth is retracted into the storage housing until the stop plug abuts the aperture in the side flange of the storage housing. An enclosure tank holds a cleaning fluid, and a pump mechanism pumps the cleaning fluid from the enclosure tank into the storage housing to moisten the cleaning cloth.
