Description

Technical Field

[0001] This invention relates to the field of medical endoscopy technology, and in particular to an endoscope with temperature measurement function. Background Technology

[0002] Endoscopes can be inserted into the human body through natural cavities or minimally invasive incisions to observe internal structures and precisely locate lesions. Combined with a camera system, the endoscope can transmit internal images of the kidneys to electronic devices, helping doctors perform various detailed examinations of the kidneys. It is suitable for use in scenarios such as kidney stone treatment, tumor diagnosis and resection, and kidney drainage. The water injection channel is independently set up to deliver fluid for internal cleaning, while the suction channel uses negative pressure to remove waste fluids and impurities during surgery, while ensuring a clear surgical field.

[0003] CN222899087 U discloses an endoscope with temperature and pressure measurement and anchoring functions, mainly comprising: a flexible endoscope tube, an anchoring balloon, an imaging module, a temperature probe, a pressure sensor, and an operating unit. The flexible endoscope tube is a flexible tube with an internal cavity, divided into three parts from head to tail: a pilot end, a curved end, and an insertion end. The pilot end has a head end base, which has an instrument channel outlet and a water / gas outlet. The imaging module and the temperature probe are mounted and limited within the head end base. The curved end is used to deflect the pilot end, and its interior has a serpentine structure that allows the pilot end to deflect. The insertion end is combined with the operating unit. The temperature probe is located directly in front of the pilot end of the flexible endoscope tube. The pressure sensor is located in the cavity at the tail end of the water / gas inlet line, or in the cavity of the water / gas inlet of the operating unit. An anchoring balloon is located between the curved end and the insertion end of the flexible endoscope tube, downstream of the curved end of the flexible endoscope tube.

[0004] CN118717024A discloses a flexible ureteroscope based on simultaneous detection of intrarenal pressure and temperature using a thin-film sensor. The ureteroscope includes a manipulator for holding and operating, with a flexible ureteroscope for surgical procedures at one end of the manipulator. The flexible ureteroscope includes a rigid support catheter fixed to the manipulator. A flexible continuum is provided at the end of the support catheter away from the manipulator, and a temperature sensor and a pressure sensor are provided at the end of the continuum. An endoscope for guidance is provided at the end of the continuum, with guide wires of the endoscope arranged along the continuum and the support catheter. A working channel is provided within the continuum, arranged along the continuum and the support catheter.

[0005] In existing technologies, endoscopes typically consist of an insertion section and a handheld section. The insertion section is inserted into the human body. Since blood and other substances may adhere to the insertion section, it needs to be cleaned and disinfected after each use to avoid cross-infection, or the endoscope should be designed for single use. Existing endoscopes that separate the insertion section from the handheld section only require disassembly for cleaning. However, during use, sensor components and tubing are usually connected to the handheld section and inserted into the insertion section. When replacing the endoscope, the components inserted into the insertion section need to be removed. However, if the handheld section malfunctions during use, it is difficult to reliably separate and replace the insertion section from the handheld section. Furthermore, it is difficult to ensure the stability of the negative pressure in the suction channel at the disassembly and disassembly points. Frequent installation and disassembly can easily affect the sealing of the suction channel. Summary of the Invention

[0044] In existing technologies, endoscopes typically consist of an insertion section and a handheld section. The insertion section is inserted into the human body. Since blood and other substances may adhere to the insertion section, it needs to be cleaned and disinfected after each use to avoid cross-infection, or the endoscope should be designed for single use. Existing endoscopes that separate the insertion section from the handheld section only require disassembly for cleaning. However, during use, sensor components and tubing are usually connected to the handheld section and inserted into the insertion section. When replacing the endoscope, the components inserted into the insertion section need to be removed. However, if the handheld section malfunctions during use, it is difficult to reliably separate and replace the insertion section from the handheld section. Furthermore, it is difficult to ensure the stability of the negative pressure in the suction channel at the disassembly and disassembly points. Frequent installation and disassembly can easily affect the sealing of the suction channel.

[0045] This invention provides an endoscope with temperature measurement function, such as... Figure 1 As shown, in this embodiment, the endoscope includes an operating section 100 and a flexible endoscope tube 200. The flexible endoscope tube 200 is configured as an insertion section, and an end assembly is provided at the end of the flexible endoscope tube 200. The end assembly includes a temperature measuring module, a camera module, and an illumination module. The temperature measuring module is a module containing a temperature sensor, used to acquire the temperature value inside the human body in real time. The camera module is used to acquire surgical images, and the illumination module provides sufficient light source to the camera module to ensure clear images. Both the operating section 100 and the flexible endoscope tube 200 are provided with a fluid supply channel 300, a suction channel 400, and a transmission medium channel 500. The fluid supply channel 300 is used to inject water or air for water cleaning, air injection to expand cavities, etc. The suction channel 400 is connected to a negative pressure mechanism to remove waste fluid and other impurities from the surgical area through negative pressure suction, ensuring a clear field of vision. The transmission medium channel 500 is provided with a signal transmission medium, such as a copper wire, for signal transmission, etc.

[0046] To facilitate easy removal of the flexible endoscope catheter 200 from the operating section 100, such as Figure 2As shown, the flexible endoscope catheter 200 is detachably mounted on the operating part 100 via a connecting component 600. The connecting component 600 comprises a locking member 605, a sealing tube 601, an elastic contact 602, and a sealing member 604. The locking member 605 can lock the operating part 100 and the flexible endoscope catheter 200 together, and correspondingly, it can also unlock the operating part 100 and the flexible endoscope catheter 200 to separate them. The sealing tube 601 is mounted on the operating part 100 or the flexible endoscope catheter 200 and communicates with the liquid supply channel 300. In this embodiment, the sealing tube 601 is mounted on the operating part 100, and can be inserted into the liquid supply channel 300 of the flexible endoscope catheter 200. To achieve a seal during connection, a skirt is provided on the outer wall of the sealing cannula 601 to improve sealing performance. For signal transmission during connection and disconnection, elastic contacts 602 are provided on both the operating part 100 and the flexible endoscope guide tube 200. The elastic contacts 602 are connected to the transmission medium channel 500. When the operating part 100 and the flexible endoscope guide tube 200 are connected, the two elastic contacts 602 abut against each other; when disconnected, the two elastic contacts 602 separate, thus achieving the switching on and off of signal transmission. On opposite sides of both the operating part 100 and the flexible endoscope guide tube 200, abutment tube 603 communicating with the suction channel 400 is provided. The two abutment tubes 603 have the same structure and can abut against each other. A sealing element 604 is provided at the connection point of the two abutment tubes 603, which seals the abutment tubes 603 when the operating part 100 and the flexible endoscope guide tube 200 are connected.

[0047] To ensure stable negative pressure suction when the operating section 100 and the flexible endoscope catheter 200 are connected, a seal is made between the two connecting tubes 603, such as... Figure 3 As shown, the sealing element 604 is configured as a sealing gasket 6041, a sealing sleeve 6042, and a clamping unit. The sealing gasket 6041 is placed between the two abutment pipes 603 to provide compensation between the two abutment pipes 603 and seal between them. The sealing sleeve 6042 has a cylindrical structure and is fitted over the outside of the two abutment pipes 603, including the connection between the two abutment pipes 603 from the outside. A sealing cavity is formed between the inside of the sealing sleeve 6042 and the outer wall of the abutment pipes 603. A sealing adjustment is provided between the sealing sleeve 6042 and the abutment pipes 603 to ensure sealing performance. The clamping unit is used to improve sealing performance. This clamping unit can push the two abutment pipes 603 closer together when there is leakage between them, thereby resealing between them.

[0048] In addition, a support frame is set inside the sealing gasket to prevent the sealing gasket from deforming under long-term negative pressure, thus affecting the sealing performance.

[0049] To ensure stable negative pressure suction, the 603 connector should be resealed in case of leakage; Figure 4 As shown, the clamping unit is configured with transmission wheels 6043, transmission gears 6044, a moving frame 6045, transmission racks 6046, a sliding rod 6047, and a return spring 6048. Four transmission wheels 6043 are symmetrically arranged on both sides of each abutment tube 603. The transmission wheels 6043 are rotatably mounted inside the sealing cavity via a rotating shaft, allowing them to rotate. Transmission gears 6044 are provided on the exterior of both abutment tubes 603, fixed to the abutment tubes 603, and meshing with the transmission wheels 6043. When the transmission wheels 6043 rotate, the transmission gears 6044 drive the abutment tubes 603 to move, bringing the two abutment tubes 603 closer together. The moving frame 6045 is located inside the sealing cavity, and two symmetrically arranged transmission racks 6046 are mounted on the moving frame 6045. Two transmission gears are respectively set on opposite sides of the two transmission wheels 6043, and the transmission rack 6046 meshes with the side of the transmission wheels 6043 to drive the transmission, thereby realizing that the movement of the moving frame 6045 synchronously drives the two transmission wheels 6043 to rotate, and the two transmission wheels 6043 rotate in opposite directions; regarding the sliding rod 6047, one end of the sliding rod 6047 is connected to the moving frame 6045, and the other end extends outward through the sealing sleeve 6042; so that the moving frame 6045 moves together when the sliding rod 6047 moves. A sealing strip is provided at the connection between the sliding rod 6047 and the sealing sleeve 6042 to ensure sealing; a limiting part is provided on the side of the sliding rod 6047 away from the moving frame 6045. The limiting part prevents the sliding rod 6047 from completely entering the sealing cavity. The return spring 6048 is set outside the sealing sleeve 6042 and is sleeved on the sliding rod 6047.

[0050] In this embodiment, the transmission wheel 6043 is configured to rotate in both directions. During disassembly, it is only necessary to pull the sliding rod 6047 outward to drive the transmission wheel 6043 to rotate in the opposite direction, so that the two abutment pipes 603 move away from each other, making it easy for the abutment pipes 603 to separate quickly and achieve rapid disassembly.

[0051] To facilitate the installation and removal of the operating unit 100 and the flexible endoscope catheter 200, such as Figure 2 and Figure 3As shown, the locking component 605 includes a threaded connection portion 6051 and a threaded sleeve 6052. The operating part 100 and the flexible endoscope guide tube 200 are both provided with threaded connection portions 6051 on opposite sides. A threaded connection portion 6051 refers to a portion with external threads on its exterior. A threaded sleeve 6052 is threaded onto the threaded connection portion 6051, and an internal thread is provided on the inner wall of the threaded sleeve 6052. The threaded sleeve 6052 can rotate and move on both threaded connection portions 6051. When the threaded sleeve 6052 moves to connect both threaded connection portions 6051 simultaneously, it connects the operating part 100 and the flexible endoscope guide tube 200. When the threaded sleeve 6052 is only connected to one threaded connection portion 6051, the operating part 100 and the flexible endoscope guide tube 200 are separated.

[0052] When the operating part 100 or the flexible endoscope catheter 200 needs to be disassembled and replaced during or after the operation, the operating part 100 and the flexible endoscope catheter 200 are separated by rotating the threaded sleeve 6052; when connecting, the sealing tube 601 is inserted into the fluid supply channel 300, the elastic contact pieces 602 abut against each other, and the two abutting tubes 603 abut against each other to seal.

[0053] When the seal between the two abutting tubes is not tight, the suction force in the suction channel 400 will draw out the gas in the sealing cavity, causing the air pressure in the sealing cavity to decrease. The sliding rod 6047 overcomes the elastic force of the return spring 6048 and moves into the sealing cavity. Simultaneously, it drives the moving frame 6045 and the transmission rack 6046 to move closer to the abutting tube 603, driving the transmission wheel 6043 to rotate. This pushes the two abutting tubes 603 closer to each other, re-sealing the abutting tubes 603 and automatically solving the problem of leakage due to poor sealing.

[0054] In addition, an elastic sleeve (not shown in the figure) is provided at the connection of the two abutment pipes 603. The elastic sleeve is sleeved on the outside of the two abutment pipes 603 and wraps around the connection. When the connection of the abutment pipes 603 is not sealed tightly, the elastic sleeve can deform under the attraction of negative pressure and indent inward to seal the gap at the connection, thereby improving the sealing performance.

[0055] The connecting component 600 allows for easy installation and disassembly of the flexible endoscope catheter 200 and the operating unit 100, and enables quick replacement during use. This significantly reduces the replacement time when the operating unit 100 malfunctions during surgery, allowing for disassembly and replacement without removing the flexible endoscope catheter 200. Furthermore, the sealing component 604 ensures that if the contact tube 603 leaks, it can be automatically resealed by the contact unit, guaranteeing a tight seal during use.

[0056] To facilitate convenient replacement in case of damage to the supply line 704 and the negative pressure line 705, such as Figure 5 As shown, an insertion slot 101 is provided on the operation unit 100. An opening / closing element 800 and an insertion element 700 are inserted into the insertion slot 101. The bottom of the insertion slot 101 is connected to the liquid supply channel 300 and the suction channel 400. The opening / closing element 800 can open and close the liquid supply channel 300 and the suction channel 400. One end of the insertion element 700 is connected to the opening / closing element 800, and the other end is connected to the liquid supply pipe 704 and the negative pressure pipe 705. The liquid supply channel 300 and the suction channel 400 are connected to the opening / closing element 800 and the insertion element 700 in sequence, and then connected to the liquid supply pipe 704 and the negative pressure pipe 705. The opening / closing element 800 and the insertion element 700 can be removed from the insertion slot 101. The insertion element 700 can be directly removed for replacement, and the liquid supply pipe 704 and the negative pressure pipe 705 can be replaced together.

[0057] like Figure 6 and Figure 7 As shown, the connector 700 is configured as a first connecting cylinder 701, a second connecting cylinder 702, and a detection cylinder 703, with the detection cylinder 703 located between the first connecting cylinder 701 and the second connecting cylinder 702. Each of the first connecting cylinder 701, the second connecting cylinder 702, and the detection cylinder 703 is provided with a liquid supply channel and a suction channel. The liquid supply channel and the suction channel in the first connecting cylinder 701, the second connecting cylinder 702, and the detection cylinder 703 are sequentially connected. The first connecting cylinder 701 is connected to the liquid supply pipe 704 and the negative pressure pipe 705, and the second connecting cylinder 702 is connected to the opening and closing component 800. The detection cylinder 703 is equipped with a sensing unit for detecting flow rate and negative pressure. The sensing unit includes at least a flow rate detection unit located in the liquid supply channel 300 and a pressure detection unit located in the suction channel 400. The two sides of the detection cylinder 703 are respectively connected to the first connecting cylinder 701 and the second connecting cylinder 702 by bolts.

[0058] To improve the connection stability and sealing performance of the first connecting cylinder 701, the second connecting cylinder 702, and the detection cylinder 703, bosses 706 are provided on the first connecting cylinder 701 and the second connecting cylinder 702, with the bosses 706 positioned on the side facing the detection cylinder 703. Grooves are formed on both sides of the detection cylinder 703, their shapes matching those of the bosses 706. The grooves allow the bosses 706 to be inserted for connection and sealing, and a sealing layer is provided within the grooves. Limiting rods 707 are offset from the first connecting cylinder 701 and the second connecting cylinder 702. Each of the two connecting cylinders 702 is equipped with two symmetrically arranged limiting rods 707. Four limiting holes are provided on the detection platform, and the limiting rods 707 can be inserted into the limiting holes. Through the cooperation of the groove and the boss 706 for limiting and the positioning of the limiting holes and the limiting rods 707, the precise connection between the first connecting cylinder 701, the second connecting cylinder 702 and the detection cylinder 703 is achieved through double positioning, ensuring the precise connection between the liquid supply channel 300 and the suction channel 400. The connection is stable, and it is convenient to disassemble the detection cylinder 703 for maintenance of the internal detection unit.

[0059] Due to prolonged use, the supply tube 704 and suction tube are constantly twisted and folded, and the endoscope needs to be rotated, which can cause the supply tube 704 and suction tube to twist, break, or age. With the above-mentioned connector 700 and connector slot 101, the supply tube 704, suction tube and connector 700 can be easily replaced as a whole, which is convenient to use and quick to replace. At the same time, after disassembly, the inside of the operating parts can be easily cleaned through the connector slot 101.

[0060] To ensure the airtightness of the connector 700 connection, an airtightness detection channel 708 is provided on the first connecting cylinder 701 and the detection cylinder 703. The airtightness detection channel 708 is connected to the air supply mechanism. After the first connecting cylinder 701, the second connecting cylinder 702 and the detection cylinder 703 are installed, an airtightness test is performed. Air is supplied to the airtightness detection channel 708 of the first connecting cylinder 701 through the air supply mechanism. The detection unit in the detection cylinder 703 detects the air pressure and detects whether there is any leakage, so as to ensure the integrity of the seal.

[0061] In order to enable convenient disconnection of the fluid supply channel 300 and the suction channel 400 in case of emergency; such as Figure 8 and Figure 9As shown, the opening and closing component 800 is configured as a positioning cylinder 801, a partition 802, a rotating cylinder 803, and a driving component. The positioning cylinder 801 is installed at the bottom of the insertion slot 101. A positioning plate is provided on one side of the positioning cylinder 801, and a positioning groove is provided on the positioning plate. The positioning plate and positioning groove match the structure inside the operating part 100 to position the installation of the positioning cylinder 801 and ensure the stability of the connection between the positioning cylinder 801 and the liquid supply channel 300 and the suction channel 400. The partition 802 is vertically set inside the positioning cylinder 801, dividing the interior of the positioning cylinder 801 into two cavities, namely the liquid flow cavity and the suction cavity. The liquid flow cavity inside the positioning cylinder 801 is connected to the liquid supply channel 300 and the suction channel 400. Channel 300 is connected, and the suction cavity is connected to the suction channel 400. The rotating cylinder 803 is located inside the positioning cylinder 801, and the outer wall of the rotating cylinder 803 is in contact with the inner wall of the positioning cylinder 801. A liquid outlet 8031 ​​and a suction outlet 8032 are provided on the rotating cylinder 803. The liquid outlet 8031 ​​and the suction outlet 8032 can be connected to the liquid supply channel 300 and the suction channel 400, respectively. The driving component is used to drive the rotating cylinder 803 to rotate. When the rotating cylinder 803 rotates and the liquid outlet 8031 ​​and the suction outlet 8032 are misaligned with the liquid supply channel 300 and the suction channel 400, the liquid outlet 8031 ​​and the suction outlet 8032 close, cutting off the liquid supply channel 300 and the suction channel 400.

[0062] In order to stably drive the rotating cylinder 803 to rotate directly from the outside; such as Figure 10 and Figure 11 As shown, the driving components are configured as a slide table 804, a limiting rack 805, a first adjusting gear 806, a second adjusting gear 807, a connecting rod, a knob 808, and an adjusting spring 809. The slide table 804 is located inside the operating part 100, on one side of the positioning cylinder 801. The limiting rack 805 is slidably mounted on the slide table 804, and a strip-shaped groove is provided on the slide table 804 to allow the limiting rack 805 to slide stably on the slide table. The first adjusting gear 806 is mounted on the rotating cylinder 803, so that when the first adjusting gear 806 rotates, it can drive the rotating cylinder 803 to rotate synchronously. The first adjusting gear 806 and the limiting rack 807 are connected. 5. The meshing transmission causes the first adjusting gear 806 to rotate when the limiting rack 805 moves; the second adjusting gear 807 is disposed on the limiting rack 805, and the knob 808 is disposed outside the operating part 100, allowing the user to operate the knob 808 directly from the outside; the connecting rod connects the knob 808 and the second adjusting gear 807, so that the connecting rod moves synchronously with the second adjusting gear 807; the adjusting spring 809 is disposed on the side of the second adjusting gear 807 away from the knob 808; the operation of the knob 808 is divided into pressing and rotating, and when the knob 808 is pressed, the second adjusting gear 807 can move to mesh with the limiting rack 805.

[0063] When it is necessary to urgently cut off the liquid supply channel 300 and the suction channel 400, the user presses the knob 808 inward, causing the second adjusting gear 807 to move and engage with the adjusting gear. Then, the user rotates the knob 808, which simultaneously drives the second adjusting gear 807 to rotate, thereby driving the limiting rack 805 to rotate, which in turn drives the first adjusting gear 806 to rotate. The rotating cylinder 803 rotates together with the first adjusting gear 806, causing the liquid outlet 8031 ​​and the suction outlet 8032 to misalign, cutting off the liquid supply channel 300 and the suction channel 400. The knob 808 and the second adjusting gear 807 then reset, and the second adjusting gear 807 disengages from the limiting rack 805. When it is necessary to reopen the liquid supply channel 300 and the suction channel 400, the above operation is repeated by rotating the knob 808 in the opposite direction.

[0064] The drive mechanism allows for manual shut-off of the liquid supply channel 300 and the suction channel 400 in emergency situations, ensuring installation safety and timeliness and preventing delays in stopping the power source. Furthermore, the design requiring a press for adjustment prevents accidental activation during normal use.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
