Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0034] The present invention provides a foldable and curly device for cutting and taking out body cavity of minimally invasive surgical resections. After being folded and curled outside the body, it is pre-placed in an inserting sleeve, and the inserting sleeve is inserted into the puncture sheath of the operating hole after the diseased tissue is excised. Then push the device into the body cavity, pull out the insertion sleeve from the puncture sheath and discard it, and connect the bag mouth to the outside with a thread;

[0035] After the device is deployed in the body cavity, a net-shaped cutting wire saw is formed. The operator puts the tissue to be cut into the bag, tightens the bag to draw the thread, lifts the bag to the inner opening of the puncture sheath, and withdraws it together with...

Abstract

The invention discloses a foldable internal-cutting removing device for minimally invasive operation excision objects. The device comprises three layers, wherein the outer layer is a transparent isolation bag, the middle layer is a cutting layer, and the inner layer is a transparent protecting layer. Two rack wires are movably connected, are perpendicular after axially rotating for unfolding, and are parallel after being folded. Each rack wire is provided with a pair of mutually perpendicular circular rings at the interval of 0.5-1mm. The pair of circular rings respectively guide cutting wires which are parallel with or perpendicular to the rack wires. The front ends and the tail ends of the cutting wires in the same travelling direction are respectively collected on two operating rods. When in use, two operators in opposite positions lift the corresponding operating rods, and cut the minimally invasive operation excision objects in the cavity into horizontal strips at one time by utilizing the net-shaped multiple wire saw cutting principle, therefore, the invention is convenient for the operators to remove the excision objects out of narrow cavascope or endoscope holes one by one, and has the advantages of small invasion, monitor and control under scopes, high operation safety and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a body cavity cutting and taking-out device for minimally invasive surgical resections that can be folded. Background technique [0002] Laparoscopic surgery is a minimally invasive surgical method in which an incision of about 0.5 to 1 cm is made on the body surface, and then pierced into a puncture sheath, and special surgical instruments are inserted into the puncture sheath to complete the surgical operation in the body cavity, including cranioscopic, thoracoscopic, Laparoscopy, retroperitoneoscopy, mastoscopy, etc. Endoscopic surgery is a surgical operation technique that puts a speculum into the natural orifice of the human body under direct vision, including gastroscopy, colonoscopy, sinusoscopy, colposcopy, hysteroscopy, etc. The development in recent years has gradually blurred the boundaries between the two, and a variety of robotic surgical devices...
