The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
The operating theater instruments of one group of Wicresoft's drain of the present utility model mainly is made up of drainage tube 11, seal wire 40, puncture needle 60 and incision of skin cutter 30.
Shown in Fig. 1 to 12, drainage tube 11 has the front end mouth of pipe 111 and rear tab 112, and is provided with drainage tube side opening 113 on its front end tube wall; Drainage tube 11 is straight tube or " L " shape bend pipe, and the sign 114 (position of sign is opposite with the drainage tube bending direction) of demonstration bending direction is arranged in the rear tab 112 of bend pipe.During if any inflating catheter 14 and inflating balloon 12, then indicate the direction (position of inflating catheter is opposite with the drainage tube bending direction) of drainage tube 11 bendings by the position of inflating catheter 14 and inflating balloon 12.Preferably, on drainage tube 11, be fixed with fixture, this fixture comprises inflating balloon 12, reaches clamp 13, inflating balloon 12 links to each other with inflation piston 141 by inflating catheter 14, this inflating balloon 12 is fixed in the front portion of this drainage tube 11, this inflating catheter 14 is located on the tube wall of drainage tube 11, and its front end has inflating catheter opening 121 to be communicated with the inner chamber of inflating balloon 12.Clamp 13 is fixed on the drainage tube 11 of inflating balloon 12 rear sides.There is the part of drainage tube to increase hard portion 15 between inflating balloon 12 and the clamp.
As shown in figure 13, incision of skin cutter 30 comprises handle of a knife 32 and is located at the cutter hub 31 of these handle of a knife 32 front ends that this cutter hub comprises the blade of front end and the root of rear end, the point of a knife of giving prominence to before the middle part of this blade is oriented.The root of cutter hub 31 is fixed on the front end face of this handle of a knife, and forms limited step portion 33 between the front end face of the surface of this root and this handle of a knife.Preferably, the front end of point of a knife to the distance of handle of a knife front end face is 0.2～3.0cm.Like this, when vertical feed, limited step portion 33 can avoid depth of cut too dark, and the skin incision that incision of skin cutter 30 is cut can just be inserted drainage tube 11, to reduce wound, reaches cosmetic result.
As shown in figure 14, seal wire 40 comprises the hard section of being made by hard material 41 and is located at made by soft material soft section 42 of this hard section front end, and this hard section 41 and this diameter of soft section 42 are all less than the aperture of the internal diameter and the front end mouth of pipe 111 thereof of drainage tube 11.Preferably, also comprise supporting tube, as shown in figure 15, the diameter of the vertical passage of this supporting tube is greater than the external diameter of seal wire 40, and the external diameter of supporting tube is less than the internal diameter of drainage tube 11.Supporting tube has front opening 52 and tail end opening 53.
As shown in figure 16, it is hollow-core construction for a puncture needle 60, syringe needle 62 sealings of this puncture needle 60 and be blunt nosed, preferably, for bullet-headed.On the front end side wall of puncture needle 60, be provided with the side opening 63 that is communicated with its vertical passage 61.Be provided with the tail end opening 64 of union joint in the rear end of puncture needle 60.
As shown in figure 17, lift hook 80 comprises the pulling part 83 at middle part and is positioned at the crotch portion 82 of its both sides that integral body is " Ω " shape.
Use the operational approach of operating theater instruments of above-mentioned Wicresoft drain as follows:
One, closed drainage of thoracic cavity operation:
Earlier with ordinary syringe row local anaesthesia, and puncture take out gas or liquid (, can omit above step) as rabat before the art and ultrasonic to confirm diagnosis person; Do a little otch at point of puncture with incision of skin cutter 30 then; Again puncture needle 60 is linked to each other with syringe, punctures in the thoracic cavity, take out behind the gas, seal wire 40 is inserted in the thoracic cavity; Under seal wire 40 guidings, thin drainage tube 11 is imported in the thoracic cavity, and link to each other then with the breast bottle; Have inflating balloon 12 as thin drainage tube 11, be close to thoracic wall then with inflating balloon 12 inflations, and with inflating balloon 12; At last with clamp or the fixing thin drainage tube 11 of transparent rubberized fabric.When thin drainage tube 11 cross section internal diameters during obviously greater than the diameter of section of seal wire 4, supporting tube 50 pavilions can be gone in the thin drainage tube 11, again seal wire 40 is passed guide support conduit 50, under the guiding of seal wire 40, thin drainage tube 11 is inserted the thoracic cavity, again seal wire 40 is together transferred to together with supporting tube 50, then thin drainage tube 11 is connected with the breast bottle.
Use the operating theater instruments of Wicresoft of the present utility model drain, can put pipe through the 4th intercostal of anterior axillary line and midaxillary line, so both can farthest avoid the damage of abdominal viscera, can make the drain otch more hidden again, particularly for young women, after they put on medicated bra, can hide the drain otch.When selecting straight thin drainage tube 11 for use, the side opening 63 that makes puncture needle 60 by adjustment and then guide seal wire 40 up or down up or down, the most carefully drainage tube 11 guide up or down; When selecting bend pipe for use, the adjustment of side opening 63 directions by puncture needle 60 and utilize the bending of drainage tube 11 itself, (drainage tube 11 upwards is convenient to drain gas up or down to adjust drainage tube 11; Drainage tube 11 is downward, is convenient to draining fluids).
This shows that present embodiment is inserted method by adopting the drainage tube 11 under seal wire 40 mediations, can reduce operation wound and reduce operational risk; Adopt inflating balloon 12 to do internal fixation, clamp or adhesive plaster are done external fixation, can avoid using sutures, as much as possible Wicresoft; Adopt incision of skin cutter 30 to do skin incision, the skin incision size can just insert selected drainage tube 11 (otch be longer than slightly drainage tube 11 perimeter of section 1/2nd), can dwindle skin incision, and depth controlled be built in only cutting skin, the postoperative cosmetic result is good.
Two, abdominal cavity and pericardial sac drainage:
When carrying out abdominal cavity and pericardial cavity drain, cut skin with the incision of skin cutter after, lift hook 80 can be inserted in the skin incision, on carry lift hook 80, and then puncture or put the pipe operation, can avoid damaging abdominal viscera.
Only be specific embodiment of the utility model below, do not limit protection domain of the present utility model with this; Any replacement and the improvement done on the basis of not violating this utility model design all belong to protection domain of the present utility model.
