DETAILED DESCRIPTION

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0030] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a component centered. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] like Figures 1 to 7As shown, the utility model provides a channel with a pressure measuring function, including an endoscope working channel 10, wherein the channel 1 also includes: a pressure transmission channel 2 and a pressure measuring catheter 6, wherein one end of the pressure transmission channel 2 passes through the channel 1 and communicates with the outside, and the other end is communicated with the pressure measuring catheter 6, and the other end of the pressure measuring catheter 6 is connected to a pressure sensor; a film 7 is sealed in the pressure transmission channel 2 and / or the pressure measuring catheter 6.

[0033] It should be noted that the channel can be an endoscope channel, a pressure measurement channel in the human body, a suction channel, a drainage channel, a flushing suction channel, etc. The film 7 can be a pressure-sensitive touch or other waterproof and air-proof film that can produce deformation.

[0034] When the channel 1 enters the body, the pressure in the body is transmitted to the film 7 through the pressure conduction channel 2. The pressure change caused by the deformation of the film 7 can be detected by a pressure sensor to know the pressure in the body. One end of the pressure measuring catheter 6 is an endoscope interface 8, and the other end is a device interface 9. The endoscope interface 8 is detachably connected to the pressure conduction connector 4 on the pressure conduction channel 2, and the device interface 9 is connected to the external pressure detection device or pressure sensor. In this way, the pressure in the body can be indirectly known by detecting the pressure of the pressure measuring catheter 6. This film 7 can effectively distinguish the sterile and contaminated ends to avoid external infection of the body during surgery. And the detection of in vivo pressure is convenient and simple.

[0035] It should be noted that the film 7 in the present invention is a functional noun, and any film that can achieve the above-mentioned pressure conduction detection can be used. For example, the film 7 can also be a bacteria-isolating film or a breathable film. According to feedback from users in the market, the effect of the bacteria-isolating film is particularly good. This film can be directly breathable but can block bacteria.

[0036] refer to Figure 6 and Figure 7 The film 7 is a pressure-sensitive film, which is flexible. When the pressure on one side of the film 7 changes, it deforms and squeezes the space on the other side, causing the pressure on the other side to change accordingly. By testing the pressure on one side, the pressure change on the other side can be known.

[0037] In a preferred solution, the channel 1 can be a disposable product that can be discarded after use, which is inexpensive and easy to manufacture. In addition, since the pressure measuring tube 6 and the pressure conducting channel 2 can be detachably connected, the remaining parts can be used as disposable products after the pressure measuring tube 6 is disassembled, which can also save costs.

[0038] In a further solution, the pressure transmission channel 2 is independent from the endoscope working channel 10. The pressure transmission channel 2 and the endoscope working channel 10 are independently arranged to prevent interference with each other and improve the accuracy of pressure detection.

[0039] In a further solution, at least one pressure conduction hole 3 is provided at one end of the pressure conduction channel 2. When the channel 1 enters the body, the body pressure enters the pressure conduction channel 2 through the pressure conduction hole 3 and acts on the film 7 to cause deformation. When the channel 1 enters the human body, the pressure in the human body cavity at the surgical operation site will enter the pressure conduction channel 2 and the pressure measuring catheter 6 through the pressure conduction hole 3 at the front end. The film 7 in the pressure conduction channel 2 or the pressure measuring catheter 6 will be deformed by the pressure, thereby squeezing the space on the other side, so that the pressure can be transmitted to the pressure sensor, and the pressure in the body can be monitored by the pressure sensor, thereby achieving the purpose of monitoring the pressure in the body.

[0040] In a further solution, the pressure conduction channel 2 includes a horizontal section and a vertical section that are connected to each other, the horizontal section is parallel to the endoscope working channel 10, the vertical section is perpendicular to the endoscope working channel 10, and a film 7 is sealed in the vertical section. The two-end design can effectively save space. The handle itself has limited space, and the endoscope working channel 10 is generally set horizontally. The design of the vertical section of the pressure conduction channel 2 on the handle can be as large as possible in the limited space.

[0041] In a further solution, the channel 1 also includes a handle, in which a first channel and a second channel are provided, which are respectively connected to the pressure transmission channel 2 and the endoscope working channel 10; the first channel is connected to the pressure measuring catheter 6, and the second channel is connected to an external device. The two channels are independent of each other, which is convenient for external pipes or devices without interference. And they are both on the handle, which is easy to operate.

[0042] Further solutions, such as Figure 2 and Figure 3 As shown, a liquid inlet channel is provided in the endoscope working channel 10, and a liquid inlet regulating valve 5 is provided on the handle, and the liquid inlet regulating valve 5 is connected to the liquid inlet channel. The liquid inlet channel in the endoscope working channel 10 can be filled with liquid to clean the surgical site, and the flow rate and switch can be adjusted directly through the liquid inlet regulating valve 5, which is convenient to use. In addition, a manual switch is provided on the liquid inlet regulating valve 5, which is more convenient and can be operated with one hand, greatly improving the convenience of surgery.

[0043] In a further solution, a liquid outlet channel is provided in the endoscope working channel 10, and a liquid outlet regulating valve is provided on the handle, and the liquid outlet regulating valve is connected to the liquid outlet channel. The liquid inlet channel in the endoscope working channel 10 can be filled with liquid to clean the surgical site, and the liquid is absorbed out through the liquid outlet channel to form a cycle. The flow rate of the inlet and outlet liquids can be adjusted by the opening of the two valves.

[0044] In a further solution, channel 1 is a disposable consumable. Since channel 1 is an item that needs to be used frequently, if it is repeatedly used and cannot be effectively sterilized, the safety and hygiene level is worrying. Therefore, it is generally designed as a disposable consumable. However, this channel 1 can not only perform surgery, but also measure pressure, and the pressure measurement is convenient and low-cost, so it can be used as a disposable consumable.

[0045] In a further solution, the pressure sensing channel is located on one side of the endoscope working channel 10, and the two are independently arranged in parallel in the channel 1. The pressure sensing channel and the endoscope working channel 10 are integrated into the channel 1 to form a whole. This makes it easy to make a disposable product, low cost, and hygienic and safe.

[0046] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
