Description

Technical field

[0001] The utility model relates to a card punching component with suction and flushing functions. [Background Technology]

[0002] In modern medical surgery, laparoscopic surgery is widely used due to its advantages of minimal trauma and rapid recovery. During surgery, the cutting and separation of tissues produces a large amount of smoke and damages blood vessels, obstructing the visual field of the surgical area and necessitating the frequent use of a suction device for both suction and blood aspiration. While existing puncture and puncture devices have vents to release smoke, they lack blood aspiration. Due to the limited number of puncture and puncture holes available during surgery, and the absence of a dedicated puncture hole for smoke and blood aspiration, the drain must be constantly removed and inserted during surgery. Furthermore, existing suction devices are often unable to bend, making it difficult to easily access deep tissues. Access to the abdominal cavity requires access through puncture and puncture holes in various locations. This often results in delayed aspiration, a poorly defined surgical field, and the risk of accidental injury to other tissues, reducing surgical efficiency and increasing surgical risk. Furthermore, currently used suction devices lack precise control over suction force, making it impossible to adjust suction force according to specific tissue characteristics and surgical needs. This can lead to unnecessary damage due to excessive suction when handling delicate tissues, or to inadequate suction when treating large amounts of fluid or bleeding, compromising surgical efficiency.

[0003] Chinese patent application number 202321434142.X discloses a stamp card, comprising: a body having a passage for surgical instruments to enter the abdominal cavity; an exhaust pipe disposed on the body and connected to the passage; and a filter connected to the exhaust pipe and comprising a filter cavity connected to the exhaust pipe and an outlet connected to the filter cavity, wherein the filter cavity is used to accommodate filter material. The passage, the exhaust pipe, and the filter cavity together form an exhaust flow channel for discharging gas from the abdominal cavity. In this way, the smoke gas generated by the surgical operation in the abdominal cavity passes through the passage, the exhaust pipe, and the filter cavity of the filter in sequence, and is discharged from the outlet connected to the filter cavity. When the smoke gas flows into the filter cavity, the smoke gas fully contacts the filter material in the filter cavity. The smoke gas is adsorbed and purified by the properties of the filter material itself, thereby protecting the health of medical staff and patients. However, it is limited to exhausting smoke through a stamp card and has a single function. [Utility Model Content]

[0004] The technical problem to be solved by the present invention is to provide a puncture card assembly with suction and flushing functions. The puncture card assembly is a dual-channel puncture card, which reduces the number of instrument replacements during surgery.

[0027] A puncture tube 1, the bottom of which is inclined, is provided with an instrument lumen 11 and an aspirator lumen 12. The lower end of the aspirator lumen 12 is provided with a limiting cavity 13, which slightly protrudes toward one side of the instrument lumen 11; the instrument lumen 11 is equipped with a matching puncture core 14;

[0028] A drainage tube 2, the front end of which is passed through the suction tube cavity 12, and the drainage tube 2 includes a tube body 21 and a suction head 22, the suction head 22 is arranged at the end of the tube body 21, and the suction head 22 is located in the limiting cavity 13; the suction head 22 is provided with a suction port 221 and a gripping portion 222, and the gripping portion 222 is located at the upper part of the suction port 221; the suction port 221 is connected to the tube body 21, and the gripping portion 222 is used for gripping by the grasping forceps 100; when smoke is generated during the surgical operation, it can be directly discharged through the drainage tube in the suction tube cavity. When it is necessary to suck blood and tissue fluid or smoke from deep tissue, the suction head 22 is first pushed out of the limiting cavity 13 through the tube body 21, and then the gripping portion 222 of the suction head 22 is gripped by the grasping forceps 100 to flexibly enter the deep abdominal tissue, thereby achieving the effect of timely blood suction and smoking.

[0029] A water inlet 23 is further provided in the middle of the tube body 21 , and a plug 24 is provided on the water inlet 23 ; when water flushing is required during surgery, the flow regulating controller 4 is closed and the water inlet 23 is connected to the flushing liquid container.
