[0002] Endoscopes are a minimally invasive medical device for examination and treatment, mainly used to diagnose and treat a variety of diseases. By entering the body through the body's natural orifices or through small surgical incisions, doctors can clearly observe the internal conditions, diagnose a variety of diseases, and perform various auxiliary treatments, such as polypectomy and lithotripsy. Ureteropelvic endoscopes are a medical device widely used in urinary system examinations and surgeries. This catheter is designed to enter the ureter and renal pelvis through the body's natural channels (such as the urethra) so that doctors can directly observe these areas for diagnosis or treatment.

[0003] Among them, real-time pressure monitoring plays a very important role in the process of ureteropyeloscopy to treat stones. By providing real-time pressure information in the renal pelvis, doctors can more accurately judge the progress of the operation and adjust the surgical strategy in time to ensure the safety and effectiveness of the operation, which helps to reduce surgical risks and the probability of postoperative complications.

[0004] Traditional endoscopes used for ureteropelvic surgery have a pressure sensor at the tip, and the monitoring port of the pressure sensor is flush with the front end surface of the endoscope's head assembly to monitor the condition of the front end of the affected area. However, when the laser is crushing the lithotripsy, the shock wave and high heat generated will directly act on the sensing components of the pressure sensor, especially for the optical fiber pressure sensor, which is very easy to cause damage to the pressure sensor, thereby affecting the progress of the operation.

[0034] The utility model provides a head end assembly 100, please refer to Figure 1 and Figure 2 The head end assembly 100 includes a tube body structure 1, a head end structure 2 and a detection structure 3, wherein the head end structure 2 is arranged at the front end of the tube body structure 1 and is conductively connected to the tube body structure 1, and the head end structure 2 has a front end face arranged forward; the detection structure 3 is arranged in the tube body structure 1 and includes a detection part 31, at least part of the detection part 31 can be exposed from the head end structure 2, so that the detection part 31 can be conductively connected to the part to be detected (such as the affected part), so that the part to be detected can be detected, and the detection part 31 is located behind the front end face, and at least part of the head end structure 2 can form a barrier in front of the detection part 31.

[0035] In this embodiment, the tube structure 1 is suitable for connecting with the endoscope body, the head end structure 2 is arranged at the front end of the tube structure 1 to extend into the patient's body, and the head end structure 2 is connected to the tube structure 1, and the treatment instrument can be extended from the tube structure 1 and extended from the front end of the head end structure 2, so as to be extended into the affected part for treatment; the detection structure 3 is arranged in the tube structure 1, and the detection structure 3 is protected by the tube structure 1, and at least part of the detection part 31 of the detection structure 3 can be exposed from the head end structure 2, so that the detection structure 3 can detect the affected part, such as real-time monitoring of the pressure value of the affected part, so that the doctor can understand in real time The condition of the affected part can be determined by the head end structure 2, so as to ensure the safety and effectiveness of the treatment; and the detection part 31 is arranged on the head end structure 2, and the detection part 31 is not located on the front end surface of the head end structure 2, so that the detection part 31 can be as close to the affected part as possible, and the detection part 31 can be blocked by the head end structure 2, so that the shock wave and / or heat generated during the operation can be blocked by the head end structure 2, and will not directly act on the detection structure 3, which can better protect the detection structure 3 from damage, thereby increasing the service life of the detection structure 3, and can enhance the user experience of the endoscope, ensuring that the operation can be carried out stably and continuously.

[0036] It should be noted that when the head end assembly 100 is applied to an endoscope, the head end assembly 100 is connected to the endoscope body through the tube structure 1 and is located at the front end of the endoscope body. The head end assembly 100 is inserted into the patient's body to detect and treat the affected area. Figure 1 As shown, when the head end assembly 100 is in normal use, the end close to the affected area is the front end, and the end opposite to the front end is the rear end. Accordingly, the description of the relevant orientation in the utility model can be used as a reference.

[0037] It can be understood that the shape of the head end structure 2 is not specifically limited, and therefore, there are many ways to form a barrier for the detection part 31 .

[0038] In one embodiment, a barrier sheet may be formed on the head end structure 2, and the barrier sheet is disposed in front of the detection part 31 or around the detection part 31, thereby forming a barrier between the detection part 31 and the affected area, preventing the shock wave or excessive heat generated during the operation from directly acting on the detection part 31, thereby better protecting the detection part 31.

[0039] Among them, the barrier can be located directly in front of the detection part 31 and be spaced apart from the detection part 31, or the barrier can be inclined to form a barrier in front of the detection part 31 to block the shock wave or heat formed in front of the head end assembly 100; or, the barrier is composed of a plurality of barrier segments, which are connected to form a wavy, arc-shaped or irregular barrier structure, so as to better protect the detection part 31.

[0040] Preferably, a receiving portion is provided on the head end structure 2, in which the detection surface of the detection portion 31 can be received, so that a barrier is formed at least in front of the detection portion 31, and the detection surface of the detection portion 31 is protected by the receiving portion. The detection portion 31 is arranged on the head end structure 2, so that the detection portion 31 can be arranged closer to the affected part, so that the detection result is more accurate, and then the detection portion 31 is protected by the receiving portion to avoid damage to the detection structure 3, so that the detection result is more reliable and the service life of the head end assembly 100 can be extended.

[0041] The head end structure 2 is roughly cylindrical in shape to ensure that the head end structure 2 can be inserted into the affected area more smoothly. Figure 1 and Figure 2 As shown, the receiving portion includes a receiving groove 211 provided on the peripheral side surface of the head end structure 2, and the receiving groove 211 is recessed inward from the peripheral side surface of the head end structure 2 along the radial direction of the tube body structure 1 to prevent the receiving portion from protruding from the head end structure 2 or forming a sharp corner point with the head end structure 2, which affects the comfort of inserting the head end structure 2 into the affected part. Among them, the detection portion 31 can be exposed from the groove side wall of the receiving groove 211, so that the detection portion 31 can be connected to the outside of the head end assembly 100, thereby better detection can be performed.

[0042] Specifically, combined Figures 3 to 5 As shown, the head end structure 2 includes a head end body 21, and an inserting section 22 protruding from the rear end of the head end body 21, the inserting section 22 is sleeved in the pipe body structure 1, the head end body 21 is located outside the pipe body structure 1, and the receiving groove 211 is provided on the peripheral side surface of the head end body 21. The notch of the receiving groove 211 is arranged radially outwardly along the pipe body structure 1, and the detection part 31 can be arranged on one of the groove side walls of the receiving groove 211, so that the detection part 31 can be connected to the outside, and a barrier is formed between the detection part 31 and the front end of the head end assembly 100, which can better protect the detection part 31.

[0043] For the pipe structure 1, if Figure 3 As shown in , the tube structure 1 includes an outer tube 11 and an instrument cavity 12. The instrument cavity 12 is arranged in the outer tube 11, and the instrument cavity 12 is used for the treatment instrument to be inserted therein; moreover, an instrument hole 213 is provided in the head end body 21 along the front-to-back direction, and the instrument cavity 12 is arranged in the plug-in section 22 and is connected to the instrument hole 213 on the head end body 21, so that the treatment instrument can pass through the instrument hole 213 to extend into the affected part to treat the affected part. The above-mentioned outer tube 11 is sleeved on the outside of the plug-in section 22 to be connected and fixed with the head end structure 2, and at the same time, the instrument cavity 12 can be covered therein. Preferably, the outer surface of the outer tube 11 is flush with the outer surface of the head end body 21, so that the outer surface of the entire head end assembly 100 is smoother, and it is smoother when inserted into the affected part, and it is not easy to scratch the patient.

[0044] Moreover, the outer tube 11 and the head end body 21 are both roughly cylindrical in shape, and the head end assembly 100 may also include a camera structure 4 and an illumination structure 5, both of which are arranged on the head end body 21, and the detection surface of the camera structure 4 and the light emitting surface of the illumination structure 5 are both arranged on the front end surface of the head end body 21, so as to be closer to the affected part and better obtain the image information of the affected part. Among them, the camera structure 4 can be set as an imaging sensor, for example, it can be CMOS (Complementary Metal Oxide Semiconductor), or it can be CCD (Charge-coupled Device, alias: image controller). Of course, the camera structure 4 can also be other image control devices suitable for use in endoscopes, without limitation. The illumination structure 5 can include LED (Light Emitting Diode), LD (Laser Diode), etc., to better illuminate the affected part, so that the camera structure 4 can obtain clearer image information.

[0045] Among them, since the volume of the camera structure 4 and the instrument hole 213 is relatively large, the camera structure 4 and the instrument hole 213 can be arranged opposite to each other along the radial direction of the head end body 21, the lighting structure 5 is arranged close to the camera structure 4, and the receiving groove 211 is located on the side of the head end body 21 close to the instrument hole 213 to ensure that the diameter of the instrument hole 213 is larger, so that the endoscope can be adapted to the use requirements of more types of therapeutic instruments. Preferably, two lighting structures 5 are provided, and the two lighting structures 5 are respectively arranged on the opposite sides of the camera structure 4, so that the lighting light is arranged more evenly. Thereby, the receiving groove 211 also has more space to ensure that the detection part 31 can be better accommodated therein and exposed, so as to ensure the detection effect and shielding effect.

[0046] Moreover, a plug-in slot 221 is formed between the plug-in section 22 and the outer tube 11, and the plug-in slot 221 is in communication with the receiving slot 211. The detection structure 3 is accommodated in the plug-in slot 221, and the detection structure 3 is fixed therein by the plug-in slot 221 and the outer shell, and the detection part 31 can be extended into the receiving slot 211, so that the detection surface of the detection part 31 is exposed in the receiving slot 211, which is convenient for detection, and other parts of the detection structure 3 can be better covered therein for protection. In particular, when the detection structure 3 is an optical fiber detection part, the optical fiber guide wire can be better protected.

[0047] Preferably, the detection structure 3 is configured as a pressure sensor, through which the pressure of the affected part can be monitored in real time, so that the doctor can understand the condition of the affected part in real time, adjust the surgical strategy, and ensure the safety and effectiveness of the surgery. Among them, the detection part 31 is the pressure detection window of the pressure sensor. Preferably, the pressure detection window is located at the front end of the pressure sensor so as to be exposed from the side wall of the receiving groove 211. And the pressure detection window can be flush with the side wall of the receiving groove 211 or can be slightly protruding from the side wall of the groove. The rear end of the pressure sensor can pass through the plug-in groove 211 to penetrate into the rear end of the tube structure 1, and is suitable for being electrically connected to the endoscope body, so as to transmit the pressure detection value to the external processing device in real time.

[0048] In addition, since the volume of the receiving tank 211 is relatively small when the head end assembly 100 is cleaned, the dirty liquid generated during the cleaning process is easily accumulated in the receiving tank 211, thereby affecting the cleaning effect. Therefore, an overflow hole 212 is also provided on the head end structure 2, and the overflow hole 212 is suitable for connecting the receiving tank 211 and the outside. When the head end assembly 100 is cleaned, since the inner diameter of the overflow hole 212 is smaller than the inner diameter of the receiving tank 211, the flow rate of the cleaning liquid can be increased, and the cleaning liquid can be better discharged from the receiving tank 211, so as to facilitate the cleaning of the detection structure 3.

[0049] Furthermore, combined with Figure 4 and Figure 5 As shown, one end of the overflow hole 212 is located on the groove wall of the receiving groove 211, and the other end of the overflow hole 212 is arranged outwardly toward the peripheral side of the head end structure 2, so that the cleaning liquid retained in the receiving groove 211 during the cleaning process can flow out from the overflow hole 212 toward the peripheral side of the head end structure 2. Moreover, during cleaning, the cylinder structure can be rotated so that the liquid in the receiving groove 211 can be thrown out better to the outside, and the cleaning effect is better.

[0050] Preferably, the receiving groove 211 is roughly square, and the length direction of the receiving groove 211 is extended along the axial direction of the tube structure 1, so that the space of the receiving groove 211 can be larger. The detection part 31 is arranged on the groove side wall of the receiving groove 211 that is arranged forward, so that the detection part 31 can be blocked by the front side wall of the receiving groove 211. The above-mentioned overflow hole 212 can be provided in plurality, and at least one overflow hole 212 can be provided on each groove side wall, so that the drainage rate is faster. Preferably, a plurality of overflow holes 212 are provided on both groove side walls of the receiving groove 211 arranged along the front-back direction, so as to better protect the detection part 31 and at the same time, the drainage efficiency is higher.

[0051] Moreover, part of the front end surface of the head end body 21 is arranged in an arc shape, so that the cavity opening of the instrument cavity arranged forward is located on the arc surface, so that part of the cavity opening of the instrument cavity can be arranged toward the circumference of the tube structure 1, so that the treatment instrument can be extended to the side of the affected part for treatment, and the treatment range is larger. Part of the overflow hole 212 is arranged on the arc surface to be arranged toward the circumference of the tube structure 1, and under the guiding effect of the arc surface, it can better flow to the outside of the head end assembly 100.

[0052] The utility model also provides an endoscope, which includes the head end assembly 100, through which the pressure of the affected part can be monitored in real time, so that the doctor can better understand the condition of the affected part, which is conducive to improving the treatment efficiency and treatment effect. In addition, the detection structure 3 is not easy to be damaged, and the service life is longer, so the service life of the entire endoscope is also longer, the maintenance cost is lower, and it is easy to clean.

[0053] Obviously, the above described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
