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

[0058] The first embodiment of the present invention is an inner cavity temperature 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 peripheral surface of the fixed tube 2 is provided with a first groove 22a for fixing a temperature sensor 21a, and the temperature sensor 21a is distributed through the outer tube. The first sensor wire 3a of the wall is connected to a first connector 4a at the proximal end of the outer cannula.

[0059] 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 t...

[0066] The second embodiment of the present invention is an inner cavity temperature and pressure measurement device, such as Figure 4 As shown, it includes an outer cannula 1 and a fixed tube 2 connected to the distal head of the outer cannula. The outer peripheral surface of the fixed tube 2 is provided with a first groove 22a for a fixed temperature sensor 21a and a second groove for a fixed pressure sensor 21b. 22b, the second groove 22b is isolated from the first groove 22a, the temperature sensor 21a is connected to the first connector 4a located at the proximal end of the outer casing through the first sensor wire 3a distributed on the outer casing wall, and the pressure sensor 21b is connected through The second sensor wires 3b distributed on the wall of the outer cannula are connected with the second connector 4b located at the proximal end of the outer cannula.

[0067] This embodiment is a modified example of the first embodiment. The difference between this embodi...

no. 3 approach

[0071] The third embodiment of the present invention is a multi-functional monitoring device for the inner cavity, such as Figure 5 As shown, it includes an outer cannula 1 and a fixed tube 2 connected to the distal head of the outer cannula. The outer peripheral surface of the fixed tube 2 is provided with a third groove 22c for fixing a multifunctional sensor 21c. The multifunctional sensor 21c is distributed via The third sensor lead 3c of the outer cannula wall is connected to the third connector 4c at the proximal end of the outer cannula.

[0072] In the inner cavity multifunctional monitoring device of this embodiment, the multifunctional sensor is installed in the first groove on the outer surface of the fixed tube circumference. The side of the head end of the functional monitoring device, compared with the traditional multifunctional sensor arranged on the head end face of the inner cavity multifunctional monitoring device, the multifunctional sensor of the present ...

Abstract

The invention discloses a lumen temperature monitoring device, a multifunctional lumen monitoring device, a lumen temperature monitoring system, a guide sheath and an endoscope. A temperature sensor or a multifunctional sensor is installed in a groove formed in the surface of the outer side of the circumference of a fixed tube; when the fixed tube is connected with the far end part of an outer sleeve, the temperature sensor or the multifunctional sensor are positioned on the side face of the head end of the lumen monitoring device; compared with the traditional monitoring device which is provided with a sensor on the end face of the head end, the temperature sensor or the multifunctional sensor of the lumen monitoring device provided by the invention not only can be used for monitoring thetemperature and other conditions of the diseased part in real time, but also can avoid the interference of other instruments or signals, so that the accuracy of 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 cavity temperature, a multifunctional monitoring device, a system, a guide sheath, and an 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 i...
