Abstract
The utility model discloses a disposable delivering catheter comprising a catheter base, an outer tube and an inner tube, wherein the inner tube is fixed on the catheter base, the outer tube is sleeved on the inner tube, a channel communicated with the inner tube is formed in the catheter base, and one end of the outer tube is connected with the catheter base in a sealed mode. Due to the fact that one end of the outer tube is connected with the catheter base in the sealed mode, after the disposable delivering catheter is inserted into a wound, air in the wound can not leak out from an end opening of the outer tube. Thus, the wound does not need to be inflated with the air to guarantee air pressure in the wound, and the disposable delivering catheter is convenient to operate.
Description
Technical field
This utility model relates to a kind of medical catheter, particularly the disposable delivery conduit of carrying medicine to use in a kind of Minimally Invasive Surgery.
Background technology
In Minimally Invasive Surgery, through the medicine that regular meeting uses hemostasis or anti, need use special-purpose delivery conduit and carry medicine to wound.Pipe inserted the conical catheter seat in used disposable delivery conduit mostly was at present, and outer tube directly is enclosed within the interior pipe outside, does not have sealing, and abdominal cavity air pressure can continue to descend in the use, need to inflate simultaneously to guarantee intraperitoneal air pressure, and complex operation, safety is low.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of outer tube gastight disposable delivery conduit.
In order to solve the problems of the technologies described above, this utility model comprises catheter block, outer tube and interior pipe, and interior pipe is fixed on the catheter block, outer tube sleeve on inner pipe, the passage of pipe in catheter block is provided with and is communicated with, an end and the catheter block of described outer tube are tightly connected.
For easy to connect, Guan Yiduan is inserted in the end of passage of catheter block in described, pipe limiting stand terrace in being provided with in the passage of catheter block, catheter block is provided with the cannelure that is looped around an end that is connected with interior pipe on the passage, and the end sealing of outer tube is inserted in the cannelure.Outer tube inserts the catheter block cannelure, guarantees the sealing in the outer tube.
In order to make the good airproof performance between outer tube and the catheter block, the internal ring side of described cannelure has tapering, and the outer end radius of internal ring side is less than inner radius.
In order to make outer tube have better positioning action, the hardness of described outer tube is shore hardness 105-110 degree, and the hardness of interior pipe is shore hardness 90-95 degree.Outer tube hardness is higher, is used for control administration position, and interior pipe is softer, can avoid damaged tissue.
Connect for the ease of syringe, the port away from an end of interior pipe on the passage of described catheter block is Rule conical bore, and the passage of catheter block is provided with the external screw thread that matches with the injector screw mouth away from an end of interior pipe.Rule conical bore of catheter block cooperates by Rule nose cone with syringe, is aided with to be threaded, and guarantees sealing, and thrust causes syringe and duct portion to break away from greatly when avoiding using simultaneously.Thrust hour also can cooperate with not threaded mouthful syringe, and use cooperation scope is wide.
For avoiding using the dummy pipe inner chamber contaminated, also include the sealing cap for the described Rule of sealing conical bore, sealing cap is connected with catheter block by connector.
For the ease of manual rotary guide pipe seat, the outside of described catheter block is provided with handle.
For the damage of minimizing instrument to wound surface, described outer tube and interior pipe are equipped with rounding away from an end of catheter block.
The beneficial effects of the utility model are: an end and the catheter block of outer tube of the present utility model are tightly connected, after this utility model inserted wound, the gas in the wound can not spill from the port of outer tube, therefore, do not need in wound, to inflate to guarantee the air pressure in the wound, easy to operate.

The specific embodiment
As Fig. 1, Fig. 2 and a kind of specific embodiment shown in Figure 3, it comprises catheter block 1, outer tube 2 and interior pipe 3, interior pipe 3 is fixed on the catheter block 1, on the pipe 3, manage 3 passage in catheter block 1 is provided with and is communicated with in outer tube 2 is enclosed within, an end of passage is interior interface tube 5, the other end of passage is Rule conical bore 6, pipe limiting stand terrace in being provided with in the end at interior interface tube 5 places in the passage in the interface tube 5, is managed on the limiting stand terrace in the end face of interior pipe is against in one end of interior pipe 3 is inserted in.Pipe 3 is communicated with the channel seal of catheter block 1 in making.
An end at Rule conical bore 6 places is provided with the external screw thread 8 that matches with the injector screw mouth on the catheter block 1.Be connected with sealing cap 7 by connector 9 on the catheter block 1, sealing cap 7 is used for sealing Rule conical bore 6.The outside of catheter block 1 is provided with handle 10, and handle 10 can be the fairshaped flank that protrudes catheter block 1, also can be other structure, as long as handle 10 can fingerhold rotate with control catheter block 1.
Operation principle: outer tube 2 and interior pipe 3 inserted wound by the rubber hole of peritoneoscope sheath, the screw thread mouth of syringe is connected with external screw thread 8 on the catheter block 1, in Rule conical bore 6 of the female Luer insertion catheter block 1 on the syringe.Medicinal liquid injects wound through syringe, catheter block 1 and interior pipe 3.
