Description

Technical Field

[0001] The utility model relates to the technical field of steam ablation guns, in particular to a water supply syringe for a steam ablation gun. Background Art

[0002] Steam ablation is an emerging minimally invasive interventional procedure that uses an endoscope to deliver a steam catheter to the affected area of a human organ. A steam ablation device uses radiofrequency energy to heat liquid water to produce high-temperature steam. When the high-energy steam encounters an obstacle and condenses into liquid water, the massive energy stored in the steam is released, destroying the diseased tissue and restoring organ function. Existing steam ablation systems primarily consist of a main control system, syringe clamp, steam generator, and catheter. The syringe is often secured to the device using a clamp similar to a syringe pump.

[0003] The piston and push-pull rod of the existing syringe are usually an integrated structure. The push-pull rod needs to be snapped into place each time for normal use. In order to solve this problem, the existing new syringe pump is integrated with a push-pull rod. At this time, the push-pull rod on the syringe becomes redundant and cannot meet the usage requirements. It needs to be broken off with force each time it is used, which not only wastes materials but also increases the safety risks of operation. In addition, during use, the existing syringe cannot quickly add other auxiliary medicines, which brings inconvenience to the surgical process. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a water supply syringe for a steam ablation gun in response to the above-mentioned deficiencies in the prior art. The syringe adopts a split structure to save production costs, while improving the portability of adding medicine during surgery, and is easy to use and highly practical.

[0005] The technical solution adopted by the present utility model is: a water supply syringe for a steam ablation gun, comprising an injection jacket, a push-pull rod and a piston, the piston being slidably installed in the injection jacket, a threaded hole being provided on the piston, a threaded head being provided at one end of the push-pull rod, the threaded head being threadedly connected in the threaded hole, a connecting sleeve being provided at one end of the injection jacket away from the push-pull rod, a detachable connecting head being provided on the connecting sleeve, a connecting pipe being connected thereto, the connecting pipe being connected to a water inlet pipe, and a dosing assembly being provided on the connecting head being connected thereto.

[0006] As a further improvement, the connecting sleeve is provided with an external thread, and the connecting head is threadedly connected to the connecting sleeve via a connecting nut.

[0007] Furthermore, the dosing assembly includes an infusion tube, a flow rate regulator, a drip pot and a bottle stopper puncture needle. One end of the infusion tube is connected to the connector, the flow rate regulator is arranged on the infusion tube, the other end of the infusion tube is connected to the drip pot, and the bottle stopper puncture needle is installed above the drip pot and connected to it.

[0008] Furthermore, a quick connector is provided between the connecting pipe and the water inlet pipe, and both ends of the quick connector are connected to the connecting pipe and the water inlet pipe respectively.

[0009] Furthermore, a rotating block is provided at one end of the push-pull rod away from the piston, and an outer edge surface of the rotating block is provided with anti-slip grooves.

[0010] Furthermore, a pipette matching the pipette needle is provided at one end of the connecting sleeve away from the injection jacket, and the pipette is plugged onto the pipette needle.

The connecting pipe 11 is connected to the water inlet pipe 13. The connecting head 9 is provided with a dosing component 2 connected thereto. The push-pull rod 4 is rotated by the rotating block 14. The push-pull rod 4 is connected to the threaded hole 6 through the threaded head 5. After the assembly is completed, the aspiration needle 16 is installed on the aspiration tube 15. The piston 3 is pulled by the push-pull rod 4 to absorb sterile water. After the sterile water is filled, the push-pull rod 4 is removed by rotation, thereby The push-pull rod 4 and the piston 3 are detachably connected, and the push-pull rod 4 can be reused, which effectively saves costs. After removing the push-pull rod 4, the syringe can be directly installed on the main body of the syringe pump as a whole. After removing the aspiration needle 16, the connecting head 9 is installed on the connecting sleeve 7 by rotating the connecting nut 10. The syringe is squeezed by the syringe pump so that sterile water enters the steam ablation gun through the connecting sleeve 7, the connecting tube 11, and the water inlet pipe 13 in sequence. During the water injection process, if auxiliary medicine needs to be added, the bottle stopper puncture needle 24 can be inserted into the medicine bottle, the flow rate regulator 22 can be opened, and the amount of medicine added can be controlled so that the medicine passes through the drip pot 23 and then enters the connecting head 9 through the infusion tube 21, and enters the steam ablation gun along with the sterile water. This structure is beneficial for the operator to quickly add auxiliary medicine during the operation, thereby improving the convenience of operation.

[0019] Specifically, an external thread 8 is provided on the connecting sleeve 7, and the connector 9 is threadedly connected to the connecting sleeve 7 through a connecting nut 10, adopting a threaded detachable connection method, which is convenient for disassembly and installation between the two and for replacing the syringe.

After the assembly is completed, the aspiration needle 16 is installed on the aspiration tube 15, and the piston 3 is pulled by the push-pull rod 4 to absorb sterile water. After the sterile water is filled, the push-pull rod 4 is disassembled by rotation, thereby realizing the detachable connection between the push-pull rod 4 and the piston 3. The push-pull rod 4 can be reused, which effectively saves costs. After disassembling the push-pull rod 4, the syringe can be directly installed on the main unit of the injection pump as a whole. After disassembling the aspiration needle 16, By rotating the connecting nut 10, the connector 9 is installed on the connecting sleeve 7, and the syringe is squeezed by the syringe pump, so that the sterile water enters the steam ablation gun through the connecting sleeve 7, the connecting tube 11, and the water inlet pipe 13 in sequence. During the water injection process, if auxiliary liquid medicine needs to be added, the bottle stopper puncture needle 24 can be inserted into the liquid medicine bottle, and the flow rate regulator 22 is opened to control the amount of liquid medicine added, so that the liquid medicine passes through the drip pot 23 and enters the connector 9 through the infusion tube 21, and enters the steam ablation gun along with the sterile water. This structure is conducive to the operator to quickly add auxiliary liquid medicine during the operation. The water supply syringe of the steam ablation gun of the utility model adopts a split structure, which saves production costs and improves the portability of adding liquid medicine during the operation. It is easy to use and has strong practicality.
