Problems solved by technology

However, there is no special connector connection between the existing flushing head and the biopsy port, and they are all glued together by rubber sleeves during use, and the connection method of the rubber sleeve adhesion is poor in sealing effect and pressure resistance, and will be damaged during use. Water leakage at the connection or disconnection between the flushing head and the biopsy port due to the increase in the water pressure of the flushing fluid occurs, and the adhesion operation is troublesome, which reduces the use effect

Embodiment 1

[0032] see Figure 1-Figure 7 , a flexible endoscopic biopsy port connector of the present invention includes a connecting tube 1, a stopper 2 and a spring 3 that are movably sleeved on the connecting tube 1, and a locking frame 4, wherein one end of the connecting tube 1 is The liquid inlet connector 5 that cooperates with the flushing tube interface, and the other end is for the biopsy port (the specific structure of the biopsy port for the gastrointestinal tract can refer to the utility model patent with the application publication number CN102697455A in the accompanying drawings). figure 2) matched liquid outlet connector, the liquid outlet connector includes a nozzle 6 for extending into the biopsy head and a sealing plate 7 for sealing the biopsy port, wherein the sealing plate 7 is provided with a An annular sealing groove 7-1 for sealing the biopsy port; the blocking piece 2 and the sealing plate 7 are located in the locking frame 4, and the locking frame 4 can be tra...

Embodiment 2

[0040] see Figure 8 The difference between this embodiment and Embodiment 1 is that an air inlet connector 9 for communicating with the connection pipe 1 is provided on the wall of the connecting pipe 1 close to the liquid inlet connector 5 . After the above-mentioned connecting air inlet head 9 is set, the air inlet pipe can be connected with the biopsy port, and then the air tightness detection of the endoscope can be completed by blowing air into the biopsy port, thereby realizing the liquid passage on the biopsy port connector. The double-pass function of ventilation and ventilation enhances the use function of the biopsy port connector.

[0041] Refer to Embodiment 1 for implementation of other implementation modes other than the above in this embodiment.

Abstract

The invention discloses a soft endoscope biopsy opening connector. The connector comprises a connecting pipe, a block piece, a spring and a locking frame, the block piece and the spring movably sleevethe connecting pipe, a liquid inlet connector is arranged at one end of the connecting pipe, a liquid outlet connector is arranged at the other end of the connecting pipe, the liquid outlet connectorcomprises a nozzle and a sealing plate, and the sealing plate is provided with an annular sealing groove; the block piece and the sealing plate are located in the locking frame, the locking frame canperform translational motion relative to the sealing plate in the direction perpendicular to the connecting pipe, the locking frame has a non-locking position and a locking position while performingtranslational motion relative to the sealing plate, and a positioning mechanism which is used for making the locking frame locked at the non-locking position and the locking position is arranged between the locking frame and the sealing plate; the locking frame is provided with a clamping part used for being clamped on a protrusion on the outer edge of a biopsy head. According to the soft endoscope biopsy opening connector, a biopsy opening and a flushing head can be connected, and the whole device has the advantages of being simple in structure, convenient to operate and good in airtight property.

Description

technical field [0001] The invention relates to a medical device, in particular to a flexible endoscopic biopsy port connector. Background technique [0002] At present, there are various types of gastrointestinal endoscopy. When using gastrointestinal endoscopy to diagnose and treat patients, due to the different conditions of the patients, some patients have more gastrointestinal tract foam or mucus or blood or excrement. When attached to the optical lens of the gastroscope, the field of view of the gastroenteroscope will be blurred, which will affect the observation of the gastrointestinal tract and increase the difficulty of diagnosis and treatment for doctors. For this reason, in use, when the gastroenteroscope needs to be flushed, the usual way is to connect the flushing head of the flushing tube with the biopsy port of the gastroenteroscope handle (this biopsy port is the entrance of the biopsy channel, and the biopsy forceps pass through the biopsy channel insertion...
