Description

Technical Field

[0001] The present invention relates to the technical field of medical endoscopes, and particularly to an endoscope with temperature measurement, pressure measurement and anchoring functions, belonging to medical devices. Background Art

[0002] Endoscopes are medical precision inspection instruments that integrate traditional optics, ergonomics, precision machinery, modern electronics, mathematics, software, etc. The main structure includes an image sensor, an optical lens, a light source, a mechanical control device, etc. Endoscopes can enter the stomach, bronchus and other parts through the oral cavity, and can also enter the inside of organs such as the ureter, bladder, uterine cavity and intestine through other natural orifices, and use the endoscope to directly observe the diseased parts inside the human body. For example, with the help of an endoscope, doctors can observe gastric ulcers, intestinal tumors, etc. With the continuous development of endoscope technology, surgical instruments (such as high-frequency electric knives, plasma knives) that can be sent into the instrument channel of the endoscope can also be applied through the instrument channel of the endoscope to perform examinations and surgical treatments (i.e., endoscopic surgeries) under the direct vision of the endoscope, such as removing kidney stones, gastrointestinal inner wall tumors, etc. Therefore, endoscope technology is currently the most convenient, direct and effective medical device for medical staff to observe diseased parts and perform minimally invasive treatments.

[0003] When performing endoscopic flexible endoscope surgery, doctors need to temporarily fix the head of the endoscopic flexible endoscope at a certain position to facilitate observing the lesion site and performing the surgery. Especially when performing endoscopic surgery on the smooth part of the intestine, the anchoring of the head of the endoscopic flexible endoscope in the intestine has always been a medical problem. Relying on the existing manual anchoring and maintaining method is time-consuming and laborious, which greatly affects the surgical process. At the same time, endoscopic surgery usually requires injecting liquid (such as injection water) or gas (such as nitrogen, carbon dioxide, etc.) to expand and clean the surgical site, separating the surgical site from the peripheral tissues to form a surgical space and a clear surgical field, and then using instruments such as high-frequency electrosurgical knives to perform the surgery. During the surgery, when the liquid or gas injected into the surgical site is excessive, or when performing negative pressure suction to clean tissue debris, there is a clinical risk of causing excessive pressure in the cavity and damaging tissue organs. Moreover, during the process of high-frequency electrosurgical knife or laser surgery, the local temperature will also increase. If it cannot be detected and controlled in time, it will also cause high-temperature damage to local tissues. Therefore, in endoscopic flexible endoscope surgery, it is very necessary to dynamically monitor the pressure and temperature of the surgical site, and it is necessary to monitor the pressure and temperature of the surgical site in real time to avoid causing tissue damage or adverse postoperative results. With the development of endoscopic flexible endoscope technology towards smaller size, if piezoelectric sensors and temperature sensors are simply added to the leading end of the existing endoscopic flexible endoscope, it will inevitably increase the volume of the leading end of the endoscopic flexible endoscope or occupy the space of the instrument channel of the endoscopic flexible endoscope, affecting the clinical application of endoscopic technology. Therefore, without changing the outer diameter of the head of the existing endoscopic flexible endoscope and without affecting the inner diameter of the existing instrument channel, a technical solution of an endoscopic flexible endoscope with temperature measurement, pressure measurement and anchoring functions is proposed to solve the urgent new clinical needs of current endoscopic technology. Summary of the Invention

[0004] To solve the above problems, the present invention provides an endoscopic flexible endoscope with temperature measurement, pressure measurement and anchoring functions, which mainly includes: a flexible endoscope catheter, an anchoring balloon, an imaging module, a temperature probe, a pressure sensor and an operation part.

[0005] The flexible endoscope catheter is a flexible pipeline with a cavity inside. According to different functions, it is sequentially divided into a leading end, a bending end and an insertion end from the head to the tail. Among them:

[0006] The leading end integrates an imaging module and a temperature probe, and is provided with an instrument channel outlet and a water / gas outlet. Preferably, in order to improve the installation efficiency, the leading end is provided with a head base, the head base is provided with an instrument channel outlet and a water / gas outlet, and the imaging module and the temperature probe are installed and limited within the head base.

[0007] The bending end is used to realize the deflection of the leading end. Inside the bending end, there is a snake bone that can make the leading end deflect. The snake bone is connected to the deflection trigger of the operation part by a metal wire. The deflection trigger pulls the snake bone forward or backward to adjust the upward or downward deflection angle of the leading end.

[0008] The insertion end is combined with the operation part for medical staff to hold and control the functions, such as controlling the entry / exit of the endoscopic catheter into / from the human body, adjusting the deflection angle of the leading end, controlling the water inlet, etc.

[0009] The flexible endoscope catheter is made of medical flexible polymer materials or metal materials, and should have physical characteristics such as tensile resistance, fold resistance, strong reducibility, smooth surface, and thin wall. For example, the flexible endoscope catheter is prepared with a three-layer composite structure. The outer layer tube is made of polyether nylon, the middle braided layer is made of 304 stainless steel wire, and the inner layer tube is made of polytetrafluoroethylene. According to the needs of different surgical sites, the common outer diameter of the flexible endoscope catheter is between 6Fr and 28Fr, and the wall thickness is between 0.1mm and 0.3mm.

[0010] The imaging module described above includes a micro camera and a cold light source. The camera and the cold light source are arranged at the leading end of the flexible endoscope catheter and are arranged side by side inside the leading end. The imaging module is connected to the data interface of the operation part at the rear end through a lead wire arranged inside the flexible endoscope catheter, and then connected to the host of the endoscope through the data interface. The cold light source is used to illuminate the camera during the image acquisition process to improve the visual effect of the surgical site. The cold light sources used include but are not limited to xenon lamp cold light sources, halogen lamp cold light sources, and LED cold light sources. With the continuous improvement of the electronic integration level, the imaging module adopts an integrated module of a micro camera and a cold light source.

[0011] The leading end of the flexible endoscope catheter is also provided with an instrument channel outlet and a water / gas outlet. The instrument channel outlet and the water / gas outlet are arranged on the outer periphery of the imaging module and are arranged side by side inside the leading end.

[0012] The instrument channel outlet is communicated with the instrument channel inlet of the operation part through an instrument channel pipeline, and the instrument channel pipeline is arranged inside the flexible endoscope catheter. During endoscopic surgery, the instrument channel pipeline is the channel for endoscopic instruments to enter and exit. The instrument channel pipeline is made of medical flexible polymer materials or metal materials. According to the needs of different surgical sites, the inner diameter of the instrument channel pipeline is between 3Fr and 24Fr.

[0013] The water / gas outlet is communicated with the water / gas inlet of the operation part through an infusion pipeline, and the infusion pipeline is arranged inside the flexible endoscope catheter. During endoscopic surgery, the required sterile liquid or gas enters and exits through the infusion pipeline. The infusion pipeline is made of medical flexible polymer materials, and the inner diameter is between 3Fr and 6Fr. In one embodiment, when preparing a flexible endoscope with a smaller outer diameter, for example, in a ureteral flexible endoscope with an outer diameter of 8.5Fr, the infusion pipeline can be combined with the instrument channel and share a cavity and an input port to reduce the space occupied inside the flexible endoscope catheter.

[0014] The temperature antenna is used to dynamically sense the temperature of the periphery of the surgical site. The temperature antenna is arranged directly in front of the leading end of the flexible endoscope catheter, just like an antenna vertically extended from the head of a bee. During the endoscopic surgery, the temperature antenna collects the temperature of the periphery of the surgical site in real time. The collected temperature is read out on the host interface of the endoscope. When the temperature of the periphery of the surgical site is abnormal, for example, when the temperature of the periphery of the surgical site exceeds 50 °C, the host interface of the endoscope gives a prompt or warning signal to avoid high-temperature damage to the periphery of the surgical site.

[0015] In one embodiment, the temperature antenna is arranged at a position 2 mm - 15 mm directly in front of the cross-section of the leading end. Preferably, the temperature antenna is arranged directly in front of the flexible endoscope catheter leading end at a distance of 5 mm - 8 mm, and the temperature antenna is arranged outside the imaging module. The temperature antenna uses a micro-thermistor, and the periphery of the thermistor is encapsulated and protected by a metal cap. For example, the periphery of the thermistor is encapsulated by a cylindrical stainless steel sleeve with a thickness of 0.1 mm and a length of 5 mm. The wiring terminal of the thermistor is welded with a wire. The wire passes through the inner cavity of the flexible endoscope catheter, extends to the tail of the flexible endoscope catheter, and is connected to the data interface of the operation part. The data interface is connected to the host of the endoscope.

[0016] In another embodiment, the temperature antenna uses a flexible temperature sensor. The temperature antenna is wrapped around the periphery of the leading end of the flexible endoscope catheter. The wiring terminal of the flexible temperature sensor passes through the inner cavity of the flexible endoscope catheter with a wire. After the wire extends to the tail of the flexible endoscope catheter, it is connected to the data interface of the operation part. The data interface is connected to the host of the endoscope. However, the disadvantage of this technical solution is that the temperature antenna is too close to the instrument channel or the water / gas outlet, and the temperature is easily interfered by the electrosurgical knife or water / gas, affecting the measurement accuracy.

[0017] The pressure sensor is located in the lumen of the tail of the water / gas infusion pipeline or is arranged in the inner cavity of the water / gas inlet of the operation part. For example, a three-way joint or branch interface is arranged at the tail of the infusion pipeline, and the pressure receptor of the pressure sensor is arranged in the inner cavity of the three-way joint or branch interface. Alternatively, the pressure receptor of the pressure sensor is arranged in the inner cavity of the water / gas inlet of the operation part. The wiring terminal of the pressure sensor is connected to the data interface of the operation part with a wire, and the data interface is connected to the host of the endoscope.

[0018] During endoscopic surgery, injecting water or gas into the surgical site, or performing negative pressure suction to create a surgical space or perform local cleaning is a common operation. However, excessive injection or suction can cause an increase in pressure at the surgical site and damage peripheral tissues. The pressure sensor continuously collects the pressure within the cavity where the surgical site is located, including positive pressure or negative pressure. The collected pressure value is read out on the main interface of the endoscope. When the pressure within the cavity where the surgical site is located is abnormal, for example, when the pressure within the cavity where the surgical site is located exceeds 15 mmHg - 20 mmHg, the main interface of the endoscope gives a pressure overload prompt or warning signal to avoid high-pressure damage to the cavity and peripheral tissues where the surgical site is located.

[0019] Due to the mucus on the inner wall of the gastrointestinal or ureteral tube that can cause the flexible endoscope catheter to slide or displace, maintaining the stability of the flexible endoscope is an important factor affecting the surgical process during endoscopic surgery. An anchoring balloon is provided between the curved end and the insertion end of the flexible endoscope catheter, and the anchoring balloon is located downstream of the curved end of the flexible endoscope catheter. For example, the anchoring balloon is set at a position 10 mm - 50 mm downstream of the curved end, preferably without affecting the free deflection of the curved end. According to the different locations of endoscopic surgery, the volume of the anchoring balloon is between 10 ml - 200 ml. The inner cavity of the anchoring balloon is connected to a one-way valve at the tail through a capillary tube. The capillary tube is arranged inside the flexible endoscope catheter, and the one-way valve is used to inject liquid or gas for expanding the balloon. The one-way valve downstream of the capillary tube is arranged on the outer periphery or the operating part of the insertion end of the flexible endoscope catheter.

[0020] The anchoring balloon is an elastic folding balloon made of a polymer material. After being injected with water or gas, the anchoring balloon can be anchored at a specified position within the human body cavity to prevent the displacement of the flexible endoscope catheter during endoscopic surgery and affect the surgical process.

[0021] To enhance the anchoring effect of the anchoring balloon on the flexible endoscope catheter, further, the outer periphery of the anchoring balloon is provided with concave-convex textures including corrugations or pockmarks to increase the friction between the outer periphery of the anchoring balloon and the gastrointestinal tract.

[0022] In another embodiment, the anchoring balloon is in an 8-shaped or dumbbell shape, and the outer periphery of the anchoring balloon is provided with concave-convex textures including corrugations or pockmarks to strengthen the stability of the anchoring.

[0023] In another embodiment, two anchoring balloons are sequentially arranged at the downstream position of the curved end of the flexible endoscope catheter, and the setting distance between the two anchoring balloons is between 20 mm - 50 mm to further enhance the anchoring effect.

[0024] The operating part is a control mechanism for medical staff to operate the endoscope and realize various endoscope functions. The operating part is provided with a deflection trigger, a water / gas inlet, an instrument inlet, a negative pressure suction port, and also a data port connected to the endoscope host. Among them, the data port integrates interfaces including power supply, temperature measurement, pressure measurement, image transmission, light source, etc.

[0025] An endoscope flexible mirror with temperature measurement, pressure measurement and anchoring functions disclosed by the present invention has the following beneficial effects: (1) A temperature sensor is arranged directly in front of the leading end of the flexible mirror catheter, which does not occupy the internal space of the leading end and can collect the temperature of the periphery of the surgical site in real time; a pressure sensor is arranged in the lumen at the tail of the infusion pipeline or at the water / gas inlet, and dynamically monitors the pressure in the cavity where the surgical site is located. When the temperature or pressure is overloaded, a prompt or warning signal can be given on the host interface of the endoscope. (2) An anchoring balloon is arranged downstream of the bending end of the flexible mirror catheter, which is beneficial to the stable anchoring of the flexible mirror catheter at a specified position in the cavity and speeds up the process of endoscopic surgery. (3) The pressure sensor is arranged in the lumen at the tail of the water / gas infusion pipeline or in the inner cavity of the water / gas inlet of the operating part. This reduces the requirements for the specification size, manufacturing process, etc. of the pressure sensor, expands the selection range of the pressure sensor, and compared with arranging the pressure sensor at the head of the flexible mirror catheter, it greatly reduces the size of the leading end of the flexible mirror catheter and at the same time reduces the technical difficulty and manufacturing cost of integration.

[0051] According to Figure 1 the shown structure, the assembly is carried out according to the following procedures:

[0052] (1) As Figure 2 shown, install and fix the imaging module 101 and the temperature probe 102 on the head-end base 105. Among them, the camera and light source of the imaging module 101 are flush with the cross-section of the leading end 100 of the flexible endoscope catheter. The temperature probe 102 is set at 5 mm from the cross-section of the leading end 100, and the temperature probe 102 is set on the outer edge of the imaging module 101. The head of the instrument channel pipeline is hermetically bonded to the instrument channel outlet 103.

[0053] (2) At 50 mm downstream of the bending end 200 of the flexible endoscope catheter and 30 mm from the insertion end 400 to the operation part 500, use a puncher to punch two small holes with a diameter of 0.82 mm respectively. Insert the capillary tubing 302 into the inner cavity of the flexible endoscope catheter. The head end of the capillary tubing 302 is hermetically bonded to the small hole downstream of the bending end 200. After the tail end of the capillary tubing 302 passes through the small hole at the insertion end 400, the tail end of the capillary tubing 302 is hermetically bonded to the one-way valve 301.

[0054] Then, the anchoring balloon 300 is sleeved into the intermediate position where the small hole is located from the leading end 100 of the flexible endoscope catheter, and the front and rear ends of the anchoring balloon 300 are hermetically bonded to the flexible endoscope catheter.

[0055] (3) The snake bone 201 and the steel wire are inserted into the inner cavity of the flexible endoscope catheter from the head of the flexible endoscope catheter and fixed at the bending end 200 of the flexible endoscope catheter. The steel wire extends out of the tail of the flexible endoscope catheter through the inner cavity of the flexible endoscope catheter, and the steel wire is connected to the operating handle of the operating part 500. When the operating handle rotates forward or backward, the snake bone 201 can deflect the leading end 100 through the bending end 200.

[0056] (4) The lead wires of the imaging module 101 and the temperature sensor 102, as well as the instrument channel pipeline, are respectively inserted into the head of the flexible endoscope catheter and extend out of the tail of the flexible endoscope catheter through the inner cavity of the flexible endoscope catheter. The lead wires are connected to the data port of the operating part 500, and the instrument channel pipeline is hermetically bonded to the instrument inlet of the operating part 500.

[0057] (5) After the above installation is completed, the head base 105 is integrally embedded and installed into the leading end 100 of the flexible endoscope catheter, and the temperature sensor 102 is exposed 4 mm - 5 mm from the leading end 100 of the flexible endoscope catheter.

[0060] (8) After installing the housing of the operating part 500, check the tightness of the fixed connection part of the pipeline.

[0061] 5. Testing: Use a data cable to connect the installed flexible endoscope to the host computer, and turn on the power to check the imaging function (clarity, brightness, etc.) of the imaging module 101, the deflection function of the leading end 100, the measurement accuracy of pressure and temperature, etc., which should meet the design requirements.

[0062] It should be noted that in this embodiment, due to the inner diameter limitation of the flexible endoscope catheter, the instrument channel and the infusion pipeline share the same cavity and inlet and outlet. When preparing a flexible endoscope with an inner diameter of 3.3 mm for the flexible endoscope catheter, the instrument channel and the infusion pipeline are separately arranged, and the inlets and outlets of the instrument channel and the infusion pipeline (i.e., the corresponding water / gas inlet 501 and water / gas outlet 104, the instrument inlet and the instrument outlet, etc.) are also separately arranged, reducing the time for occupying the cavity and rotating operations during the operation.

[0063] The above-mentioned drawings and embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention, and do not constitute any limitation to the protection scope of the present invention.
