Description
This utility model relates to the medical operation apparatus, particularly a kind of novel operation cutter.
As everyone knows, for each patient and family members thereof, wish all when performing an operation that operating time is short more good more, amount of bleeding is few more good more, and postoperative infection complication etc. does not take place.But existing at present surgical apparatus can't satisfy patient and family members' requirement fully, as the patient that need perform an operation for pars oralis pharyngis, particularly the patient of palate pharynx urethroptasty adopts the modes that routine operations excise or laser scalpel excises before, and this dual mode respectively has drawback, as adopt the routine operation mode, its operating time is longer, approximately needs more than 1 hour, even longer, and intraoperative blood loss is big, and the pharyngeal shape of postoperative is undesirable; And the mode that adopts laser scalpel perform an operation still need 30 surplus minute, though intraoperative blood loss obviously reduces, damage art district surrounding tissue in art makes postoperative cause complication such as local organization adhesion unavoidably.And it is big to buy laser scalpel kind equipment amount of investment, and general medium and small hospital is difficult to popularize.
The purpose of this utility model provides a kind of novel operation cutter with characteristics such as simple in structure, cheap, easy to operate, operating time are short.
The novel operation cutter of this utility model design comprises movable handle of a knife, described movable handle of a knife is provided with the negative electrode socket, be fixed with the interchangeable cutter hub on the movable handle of a knife, be fixed with the cutter hub pedestal by hold-down screw on the described interchangeable cutter hub, be fixed with mobile tool rest, insulating barrier and cutter hub plate on the described cutter hub pedestal from top to bottom successively; One end of described cutter hub plate is provided with the anode socket, and the other end is fixed with cutter head, and the cutter head front end is provided with blade, and the cutter head outer surface is provided with insulating barrier; Described mobile tool rest is provided with the fixedly fixing rear solid end of fore paw and mobile tool rest of mobile tool rest successively near an end of cutter head, and respectively on the cutter hub pedestal correspondence be provided with the fixedly fixing rear solid end slideway of fore paw slideway and mobile tool rest of mobile tool rest, described mobile tool rest front end is fixed with the upright shelves of the vertical mobile tool rest that has tissue fixator, and the upright shelves of mobile tool rest are provided with the cutter rail that the cutter head upper knife edge is passed through; Described cutter hub pedestal front end also is provided with the upright shelves of vertical, parallel with the upright shelves of mobile tool rest cutter hub, the cutter rail that the upright shelves of cutter hub are provided with the tissue fixator jack and cutter head is passed through; Also be fixed with S shape spring leaf below described mobile tool rest, the spring free-end withstands on the place ahead of movable handle of a knife.
Wherein, be equipped with rectangular through hole on described mobile tool rest, insulating barrier and the cutter hub plate,, mobile cutter hub and cutter hub plate played fixing and guide effect by hold-down screw.
Cutter head left surface on the described interchangeable cutter hub can be multiple shape, as most circles semicircle, zigzag, two connections.
During application, pull handle of a knife, make the upright shelves of mobile tool rest,, will desire resection organization and fix, can observe the size of desiring resection organization by the hole on cutter head and the upright shelves of mobile tool rest with the upright shelves of cutter hub and neat to front slide.Simultaneously, tissue under the excision be can fix, trachea or esophagus are strayed in case cut tissue comes off by the tissue fixator on the upright shelves of tool rest; Entering the cutter rail with rear blade cuts; Unclamp handle of a knife, cutter head is withdrawn from earlier, then, moves behind the mobile tool rest, makes the upright shelves of mobile tool rest away from the upright shelves of cutter hub, and cut tissue is together shifted out the oral cavity together with scalpel, and hands is stated promptly to accuse and finished.In cutting process, cutting of the cutting of sharp property, high-frequency electrical and high-frequency electrocoagulation carry out simultaneously, and intraoperative blood loss is few, whole cutting process about 1-3 consuming time second.
That the novel operation cutter of this utility model design has is simple in structure, cheap, easy to operate, operating time short, the characteristics such as generation of not hemorrhage in the art, cut coverage and shape ideal, other tissue of non-easy damaged art district, minimizing post-operative complication.
