Abstract

The utility model relates to a novel medical instrument for medical surgical operation, which is mainly composed of a valve body, a valve core, a ventilation cover, a sucking-cutting head, a suction head, etc. When a lobectomy of a liver is operated, the sucking-cutting device for a liver uses the characteristics that a liver is crisp, fragile and easy to suck but a blood vessel and a bile duct are flexible and are not easy to break. The utility model uses suitable negative pressure or sucking-cutting strength to suck the liver tissue instead of cutting the liver tissue on the destined cutting line, which avoids the interdiction of the blood supply of the liver and assures rapid and clear dissection and safe excision. Consequently, operation risks, operation processes and relevant postoperative complications are decreased. Besides, the sucking-cutting device for a liver can also be used for sucking-cutting crisp organ tissues of spleens, etc., the suction head of the utility model is replaced, and the utility model can be also used for sucking blood and liquid during an operation. The utility model has the advantages of simple structure and convenient operation. The operation effect is ideal by clinical application.

Description

Sucking-cutting device for liver

This utility model relates to a kind of medical science surgical medical equipment of novelty.

The method of hepalobectomy is a lot, and for avoiding that unmanageable massive hemorrhage takes place in the art, so far, it is the most frequently used still separating liver parenchyma decision liver with traditional hepatic blood supply blocking-up back with passivity such as handle of a knife, fingers with the dissecting knife incision.Easily cause after the hepatic blood supply blocking-up in various degree liver function injury and art in hemodynamic change, therefore, easily increase the danger and the post-operative complication of operation, and increase surgical operation step, prolong operating time.Both just with the disconnected liver of advanced apparatuses such as ultrasound knife, have also that to cut off the line place narrow, hyperamization pipe, bile duct such as can not appear free from worry, clearly at undesirable part.

Task of the present utility model is, utilizes hepatic tissue matter crisp, frangible, easily suction and blood vessel, the broken characteristics of the tough difficult suction of bile duct matter.Both need not the hepatic blood supply blocking-up during disconnected liver, and had separated without method passivity such as dissecting knife cutting and handle of a knifes again, and cut off on the line predetermined, and selected for use and fit easy negative pressure hepatic tissue " with suction for cutting " with this utility model.Reach simple to operate, it is quick clearly to cut off the dissection of line place, the disconnected liver of safety, thus reduce surgical risk and post-operative complication.

Task of the present utility model is finished like this.Shown in accompanying drawing 1,2,3,4,5.The close device of joining of spool (2) is in the axial hole of valve body (1), and its horizontal same position is shaped on three through holes of rectangular form, and all can communicate with the radial direction through hole of valve body (1); It radially is shaped on an inclined via-hole, communicates with axial three through holes.Spool (2) is shaped on a circumferential groove with the inside of valve body (1) upper surface contact surface, the circumferential boss of valve body (1) upper surface is probeed into, the outside of contact surface is shaped on a semi-circular recesses, and the inboard at right angles position of groove is shaped on three concave points, and is corresponding with the position of three through holes.Be shaped on a circumferential boss on shrouding disc (3) and valve body (1) the lower surface contact surface, probe in the circumferential groove of valve body (1).After spool (2) lower thread screwed on shrouding disc (3), the same disk cover of reuse nut (4) (3) screwed relatively, made each contact surface contact location, and spool (2) can only rotate in valve body (1), can not move up and down.Torsion spring (5) device is in the corresponding circumferential groove position of valve body (1) and spool (2), and the one end is fixed on the valve body (1), and the other end is fixed on the spool (2).The permeation lid covers on spool (2) (6) close joining, and is shaped on five through holes that diameter is inequality on the same diameter in its upper surface, and all can communicates with the radial skew through hole of spool (2).On valve body (1), its upper end probes in spool (2) semi-circular recesses and the concave point driving lever (7) by bearing pin (8) lever form device, and on valve body (1), and the external button (10) that is with stage clip (9) controls by device in its lower end.At valve body (1) radial hole two ends, an end appearance is made zigzag, and other end screw thread is fixing to be inhaled crop (11) or attract head (12).Inhale crop (11) and be drum type,, install sharp keen blade (13) in central through hole inside.Attract head (12) to be drum type, periphery is shaped on a plurality of small through hole, and communicating with central through hole forms.

Before task of the present utility model is achieved in that the operation that undergos surgery, be earlier that zigzag one end connects rubber tube with valve body (1) radial direction through hole appearance, connect the used negative pressure equipment of usual operation technique.Press button (10), twist spool (2), the right angle pylone that makes its three through hole towards after connect negative pressure equipment one end.At this moment air enters spool (2) from certain through hole of permeation lid (6), and the right angle pylone through spool (2) three through holes enters in the negative pressure equipment through valve body (1) radial hole again.When negative pressure equipment is started working, can determine the working condition of negative pressure equipment by permeation lid (6) through hole amount of air drawn.At this moment, working position of the present utility model is in closed condition.After negative pressure equipment is working properly, pressing button (10) makes driving lever (7) upper end leave concave point to enter in the groove, spool (2) is resilience automatically under the effect of torsion spring, the clear opening of its three through hole is communicated with the radial direction through hole of valve body (1), at this moment, driving lever (7) utilizes the resilience of stage clip (9) to enter in another concave point of groove, can start working.According to surgery situation, go up fixing head (12) or the suction crop (11) of attracting at valve body (1).The fixing head (12) that attracts when needing exhaustion hematocele or hydrops in the operation directly passes through valve body (1) the negative suction equipment in attracting head (12) at the effect hematochezia or the liquid of negative pressure equipment.As operation is that hepatic tissue is inhaled when cutting, the fixing crop (11) of inhaling, under the effect of negative pressure equipment, to hepatic tissue predetermined cut off to inhale on the line cut, disintegrating slag hepatic tissue and blood are cut in suction directly to be passed through the rapid negative suction equipment of valve body (1) in inhaling crop (11) in the process, wherein block hepatic tissue is then inhaled blade (13) chopping in the crop (11), in the rapid too negative suction equipment.In operation technique, twist permeation lid (6), by selection, utilize the amount that from spool (2) radial skew through hole, sucks air to five diameter through holes inequality, reaching suction shear force of the present utility model and operating rate has controlled adjustment.Cutting action need when suction suspends, and need to keep spools (2) between negative pressure equipment during the negative pressure in the valve body radial hole, can press button (10), utilize the resilience of torsion spring (5), spool (2) returns back to another closed position automatically, at this moment, the right angle pylone of spool (2) three through holes is inhaled an end of crop (11) towards valve body (1) device.By a certain through hole of permeation lid (6), the intraluminal negative pressure of valve body (1) of inhaling between crop (11) and the spool (2) is rapidly disappeared.
