Problems solved by technology

[0003] However, since the patient’s part may be in contact with different therapeutic instruments during the operation, for example, the head end of the endoscope may also be equipped with a camera device, a light source device, an energy therapy device, etc., the pressure monitoring at the end face of the endoscope lens will be Interferenced by various other devices or signals, the monitoring effect of the pressure sensor installed on the end face of the endoscope lens will be greatly affected, and accurate monitoring results cannot be obtained
In addition, the existing sensor catheter also needs to be provided with an independent pressure sensor wire to pass through, which will increase the overall size of the device, limit the application of the device, and increase the pain of the patient's operation

no. 1 approach

[0046] The first embodiment of the present invention is a cavity pressure monitoring device, such as figure 1 As shown, it includes an outer tube 1 and a fixed tube 2 connected to the distal head of the outer tube. The outer surface of the fixed tube 2 is provided with a groove 22 for fixing a pressure sensor 21. The sensor wire 3 is connected to a connector 4 located at the proximal end of the outer cannula.

[0047] Specifically, the distal head of the outer sleeve 1 in this embodiment is connected to the fixing tube 2, and the outer sleeve 1 can be configured as a single-layer or multi-layer structure to meet the requirements of different application scenarios. The outer sleeve 1 can be a single-cavity structure, and can also be configured as a multi-lumen structure according to requirements. For example, a cavity for installing a wire can be designed on the wall of the outer sleeve 1. The wire can be a sensor or a camera installed at one end of the outer sleeve. the trans...

no. 2 approach

[0055] The invention also discloses a cavity pressure monitoring system, such as Figure 4 As shown, it includes an operation part 200 and an insertion part 100. The insertion part 100 is provided with an outer sheath 10 and an inner catheter 20 pierced through the lumen of the outer sheath. The outer sheath 10 uses a lumen pressure monitoring device , the inner chamber pressure monitoring device comprises an outer sleeve and a fixed tube connected to the distal head of the outer tube, the outer surface of the fixed tube is provided with a groove for fixing the pressure sensor 21, and the pressure sensor 21 passes through the sensors distributed on the wall of the outer tube The lead is connected to a connector at the proximal end of the outer cannula.

[0056] Specifically, the distal head of the outer sleeve 1 in this embodiment is connected to the fixing tube 2, and the outer sleeve 1 can be configured as a single-layer or multi-layer structure to meet the requirements of d...

no. 3 approach

[0063] The third embodiment of the present invention discloses a pressure guiding sheath, such as Figure 5 As shown, it includes a dilator catheter 30 and a guide sheath 40. The guide sheath 40 is provided with a hollow lumen and a front opening, and the dilator catheter 30 passes through the lumen of the guide sheath 40 and passes through the front opening of the guide sheath. It is noted that the guiding sheath 40 includes a lumen pressure monitoring device, and the lumen pressure monitoring device includes an overtube 1 and a fixed tube 2 connected to the distal head of the overtube, and a fixed pressure sensor is arranged on the peripheral surface of the fixed tube 2 The groove 22 of 21, the pressure sensor 21 is connected with the connector located at the proximal end of the outer cannula via the sensor wires distributed on the outer cannula wall, and the connector is arranged in the operating handle 50 of the pressure guiding sheath.

[0064] The introducer sheath is us...

Abstract

The invention discloses a lumen pressure monitoring device, a lumen pressure monitoring system, a pressure guide sheath and an endoscope. The lumen pressure monitoring device comprises an outer sleeveand a fixed tube connected with the far end part of the outer sleeve; a groove for fixing a pressure sensor is formed in the surface of the outer side of the circumference of the fixed tube; the pressure sensor is connected with a connector, positioned at the near end of the outer sleeve, by means of sensor leads distributed on the wall of the outer sleeve. The pressure sensor is positioned on the side face of the head end of the lumen pressure monitoring device; compared with the traditional lumen pressure monitoring device which is provided with a pressure sensor on the end face of the headend, the pressure sensor of the lumen pressure monitoring device provided by the invention not only can be used for monitoring the pressure of the diseased part in real time, but also can avoid the interference of other instruments or signals, so that the accuracy of pressure monitoring is further improved; therefore, the device has a very high practical value.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an inner chamber pressure monitoring device, system, pressure guiding sheath and endoscope. Background technique [0002] Generally, when performing endoluminal surgery, it is necessary to monitor the pressure of the patient site in real time, so that the surgery can be carried out smoothly under appropriate pressure conditions. At present, a pressure monitoring device, such as a pressure sensor, is usually installed on the head end of the endoscope or guiding sheath. The pressure monitoring device transmits the measurement information to the transmission interface of the operation end through the wire, and then the transmission interface transmits it to the external display processing. The system finally displays the pressure information on the external monitor in real time, and the medical staff can know and adjust the pressure status of the patient's part in real time, which...
