Abstract
The utility model provides a multipurpose expansible thoracic drainage trocar, which comprises a cannula sheath and a trocar core. A trocar tip arranged at the front end of the trocar core forms a conical shape, and the trocar core is provided with a negative pressure channel along an axial direction. The far end of the cannula sheath is provided with a side hole, and the near end of the cannula sheath is communicated with a side tube; the outer wall of the far end of the cannula sheath is also provided with a gas-liquid bag; the near end of the cannula sheath is communicated with the gas-liquid bag by a gas-liquid tube through the inside of the wall of the cannula sheath; the near end of the cannula sheath is also communicated with the far end of the gas-liquid bag by a flushing tube through the inside of the wall of the cannula sheath; the flushing tube is penetrated to the far end of the cannula sheath, which is provided with an opening. The trocar not only has the function of the traditional trocar, but also can cure the liver abdominal cavity echinococcosis. The utility model has the advantages of small damage for organism, simple operation and low cost.
Description
This utility model belongs to medical apparatus and instruments, particularly a kind of surgery puncture needle.
Used before puncture needle, function singleness, big to the body tissue damage, the puncture needle bore is little, is difficult to adapt to comprehensive requirement of clinic diagnosis.Particularly for the treatment of liver abdominal cavity echinococcosis, owing to do not have ideal puncture needle and other multiple former thereby rest on operative treatment for a long time.The operative treatment wound is big, the relapse rate height, other complication in addition, bring excellent worry for patient and clinician, millions of echinococcosis patients and clinician look forward to and can reach therapeutic purposes by puncture for treating, prevent that capsule liquid from leaking, cephalomere spills plantation, the cleaning of capsule entozoa body but existing puncture needle can't solve puncture for treating, root problems such as blister cavities complication processing, thus make puncture for treating be difficult in the echinococcosis treatment, implement.
The purpose of this utility model is the multi-functional sleeve pipe puncture needle of a kind of expanding of design.It not only has the function of traditional puncture needle, has also solved the puncture for treating of liver abdominal cavity echinococcosis and liver peritoneal abscess and empyema, and little to the damage of body, and damage is simple, and is cheap.
This utility model is to have carried out a series of innovations and transformation on the puncture needle basis of the simple function that traditional nook closing member by in cover sheath and the cover sheath constitutes, mainly comprise: the horse ear shape or the pyramid needle point that change the nook closing member front end are cone tip, have negative pressure channel vertically at nook closing member, the cover sheath distal has side opening, the near-end of cover sheath is communicated with side pipe, the outer wall of cover sheath distal also has a gas-liquid capsule, there is a gas-liquid pipe in cannula sheath wall, to communicate from overlapping the sheath near-end, also has a syringe pipe in cannula sheath wall, to lead to the gas-liquid capsule with far away and be opened on the cover sheath distal from overlapping the sheath near-end with the gas-liquid capsule.
Negative pressure channel on the nook closing member can be out the negative pressure trough on the nook closing member surface, also can be out the negative pressure cavity in nook closing member.The tapering of cone tip is preferably less than 45 °.The cover sheath is set with outward slidably certain elastic fixed cover.
The utlity model has the repertoire of traditional puncture needle, and solved the root problem of liver abdominal cavity Echinococcus hydatid cyst and abscess percutaneous puncture in treating thereof.Cone tip reduces the damage to the puncture surrounding tissue, and conicity helps the inserting needle operation less than 45 °; Negative pressure channel design on side opening, side pipe and the nook closing member of cover on the sheath can be reduced or remitted the leakage of capsule liquid, cephalomere, pus and be spilt; The gas-liquid capsule is expanded after by gas-liquid pipe inflation or topping up, can the fixed cover sheath, stop blooding and prevent focus capsule liquid other position of bleeding outward; Syringe pipe can be easily to blister cavities flushing and injection.Operate very simply, and cheap, promote easily.
Describe embodiment of the present utility model and working condition in detail below in conjunction with accompanying drawing:
Fig. 1 is this utility model structural representation.
Fig. 2 is cover sheath structural representation.
Fig. 3 is the A-A cutaway view of Fig. 2.
Fig. 4 is the nook closing member structural representation.
Fig. 5 is the B-B cutaway view of Fig. 4.
During operation, at first on the side pipe (6) of cover sheath (1) near-end, connect the negative pressure device that is equipped with, on the site of puncture skin of determining, cut an osculum then, under B ultrasonic monitors, press the B ultrasonic indicated depth, make needle point (12) to the focus center through inserting needle of otch, see that pathological changes capsule liquid is after negative pressure trough (15) flows out, remove nook closing member (2) rapidly, inflate or topping up to gas-liquid capsule (14) by gas-liquid pipe (5) through the gas-liquid mouth of pipe (11) again, make gas-liquid capsule (14) expanse, in case cover sheath (1) is from the intravital blister cavities slippage of people, prevent capsule liquid, cephalomere and the pus body cavity that bleeds.Stop up toward the import of cover sheath near-end with cover sheath mouth plug (13).Continuous negative pressure suction in this process, capsule liquid and capsule content are by side opening (4), cover sheath tube chamber, side pipe (6) sucking-off, after exhausting capsule liquid and most of capsule content, through the flushing mouth of pipe (10), syringe pipe (3) injects the drug irrigation blister cavities repeatedly, liquid after the flushing is by the sucking-off of cover sheath tube chamber negative pressure, after treating that blister cavities is rinsed well, mouth of pipe epidermis stitches a pin ligation in fixed cover (7), with the fixed cover sheath, give over to puncture back drainage wash blister cavities and medication, and give over to other processing of blister cavities focus later stage, after puncture finishes, mouth of pipe plug (8) and (9) are blocked the flushing mouth of pipe (10) and the gas-liquid mouth of pipe (11) respectively, will overlap sheath mouth plug (13) obstruction and firmly overlap sheath (1) import, side pipe (6) connects drainage bottle or drainage bag.
Claims (4)
1, the multi-functional sleeve pipe puncture needle of a kind of expanding, comprise the nook closing member (2) in cover sheath (1) and the cover sheath (1), the needle point (12) that it is characterized in that nook closing member (2) front end is cone tip, nook closing member (2) has negative pressure channel (15) vertically, the far-end of cover sheath (1) has side opening (4), near-end is communicated with side pipe (6), the outer wall of cover sheath (1) far-end also has a gas-liquid capsule (14), there is a gas-liquid pipe (5) to overlap sheath (1) near-end certainly and in cannula sheath wall, communicates, also have a syringe pipe (3) to overlap sheath (1) near-end certainly and in cannula sheath wall, lead to gas-liquid capsule (14) with far away and be opened on the cover sheath distal with gas-liquid capsule (14).
2, puncture needle according to claim 1, the tapering that it is characterized in that needle point (12) is preferably less than 45 °.
3, puncture needle according to claim 1 is characterized in that negative pressure channel (15) can be out also can be out the negative pressure cavity in nook closing member (2) at the negative pressure trough on nook closing member (2) surface.
4, puncture needle according to claim 1, it is characterized in that overlapping outer being set with of sheath (1) slidably has certain elastic fixed cover (7).
