Abstract
Description
Technical Field
[0001] The invention relates to the field of medical instruments, and in particular to a multifunctional digestive endoscope treatment device. Background Art
[0002] The digestive endoscopy treatment device is a medical device used for the diagnosis and treatment of digestive tract diseases. Based on endoscopic technology, it provides a minimally invasive and precise means for digestive tract examination and treatment. Digestive tract diseases include gastrointestinal bleeding, polyps, tumors, ulcers, etc. Traditional diagnosis and treatment of digestive tract diseases usually require surgery, which is traumatic, has a long recovery time, and is accompanied by a certain risk of complications. The introduction of endoscopic technology has made non-surgical digestive tract examination and treatment possible, greatly reducing the pain of patients and improving the safety and effectiveness of treatment. Traditional digestive endoscopy equipment is mostly based on a single function, such as diagnosis or a single type of treatment. The function is relatively simple and it is difficult to meet the needs of patients with complex or multiple symptoms. At the same time, traditional equipment needs to be frequently replaced or accessories added during the treatment process, which not only affects the treatment efficiency, but also may bring the risk of secondary contamination. In addition, the operation accuracy of traditional endoscopes is low, making it difficult to perform high-precision treatment, especially in some subtle or difficult-to-reach areas.
[0003] The invention patent with publication number CN114259265B discloses a multifunctional digestive endoscope treatment device, comprising an outer tube, an inner tube and a sliding connection mechanism are arranged inside the outer tube, and the inner tube is slidably arranged inside the outer tube through the sliding connection mechanism, an endoscope and a rotating connection mechanism are arranged on the inner tube, and the endoscope is rotatably arranged on the inner tube through the rotating connection mechanism; the rotating connection mechanism includes two first fixing plates symmetrically arranged on the inner tube, and the multifunctional digestive endoscope treatment device can install the inner tube provided with an endoscope or a metal clip, an argon gas knife, a syringe, a thermal probe and other treatment equipment in the outer tube through the sliding connection mechanism, and can be replaced, and the angle of the endoscope can be adjusted through the rotating connection mechanism after installation, thereby realizing the multifunctionality of the digestive endoscope treatment device, so that it can not only install different types of diagnostic and treatment equipment, but also adjust the angle in the patient's body to explore the lesions at different positions in the patient's digestive system. However, the protective device still has the following problems when used: (1) During surgery or examination, it is contaminated by blood, body fluids, etc., affecting the clarity of the field of vision. The lack of a cleaning mechanism means that doctors cannot directly clean the lens during the operation and need to repeatedly remove the endoscope for cleaning, which not only prolongs the operation time, but also affects the continuity of the operation and the stability of the imaging, increasing the risk of infection and inconvenience in operation; (2) In some gastrointestinal examinations or treatments, especially in areas of narrowness or tissue compression, doctors need a wider operating space. The lack of a distraction mechanism limits the application of endoscopes in narrow spaces, making it impossible to effectively expand the surgical field of view, affecting the exposure of the lesion area, increasing the difficulty of the operation, and possibly causing additional damage to surrounding tissues.

[0012] Furthermore, a rope is connected to the rear end of the first instrument channel, and the rope runs through the second instrument channel; a spring is provided between the first instrument channel and the second instrument channel.
[0013] The beneficial effects of the present invention are: 1. The digestive endoscopic treatment device of the present invention combines a rotating mechanism, a pushing mechanism, a limiting mechanism and a cleaning mechanism to achieve surface cleaning around the operation, so as to keep a clear field of vision. The support rod is pushed and extended by the pushing mechanism, thereby expanding the support area and the surgical field of vision.

DETAILED DESCRIPTION
[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

Therefore, they should not be understood as limitations on the present invention.
[0032] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0033] Embodiment 1 See attached Figure 1-13 A multifunctional digestive endoscopic treatment device is shown, comprising an outer tube 1 and an inner tube 2, wherein a rotating mechanism 3 is provided between the outer tube 1 and the inner tube 2 near the front end, and a plurality of limiting mechanisms 4 are provided at the front end of the outer tube 1; the rotating mechanism 3 is connected to the limiting mechanism 4; and a plurality of cleaning mechanisms 6 for cleaning blood stains around the surgical field are connected to the front end of the limiting mechanism 4.
[0034] The cleaning mechanism 6 can rotate by setting the rotating mechanism 3. The rotation of the cleaning mechanism 6 can clean the blood stains around the surgical field, ensuring a clear surgical field, thereby providing greater operational flexibility; the limiting mechanism 4 is used to fix the relative position of the cleaning mechanism 6 during the operation.
[0035] The outer tube 1 is sleeved with a rotating drum 11, and the rotating mechanism 3 includes a rack 31, a gear 32 and a motor 33; the rack 31 is installed on the inner wall of the rotating drum 11, the motor 33 is installed on the inner tube 2, the gear 32 is connected to the motor 33, and the gear 32 is meshed with the rack 31.
[0036] The limiting mechanism 4 includes a turntable 41, a clamping block 42 and a connecting block 43; a clamping block 42 is rotatably provided on the front end wall of the outer tube 1, and the clamping block 42 is connected to the turntable 41 through the connecting block 43; the rear end of the turntable 41 is connected to the rotating drum 11, and the cleaning mechanism 6 is provided at the front end.
[0037] The cleaning mechanism 6 includes a support rod 61 and a cleaning head 62, the support rod 61 is installed on the turntable 41, and the other end of the support rod 61 is rotatably connected to the cleaning head 62; the cleaning head 62 includes a sponge pad 621 and a scraper 622, the scraper 622 is semicircular, and the sponge pad 621 is connected to the surface of one side of the scraper 622 plane, and the support rod 61 is connected to the turntable 41 through a universal ball.
[0038] The motor 33 drives the rack 31 through the gear 32 to drive the rotating drum 11 to rotate. The rotating drum 11 is fixedly connected to the rotating disk 41 to drive the rotating disk to rotate. The limiting mechanism 4 is fixed by the combination of the rotating disk 41, the clamping block 42 and the connecting block 43. When the rotating disk 41 rotates, the clamping block 42 and the connecting block 43 are driven to rotate. Under the action of the clamping block 42, the relative position of the cleaning mechanism 6 is fixed. The cleaning mechanism 6 is connected to the rotating disk 41 through the support rod 61. When the motor 33 drives and the rotating drum 11 starts to rotate, the cleaning head 62 starts to rotate due to the friction force. When the plane of the scraper faces the tissue, it stops rotating due to the friction force. Under the action of the sponge pad 621, it starts to clean the surrounding blood or body fluids to keep the surgical field clear. This design simplifies the cleaning steps during the operation, ensures the imaging effect, and facilitates the doctor to operate accurately.
[0039] The inner tube 2 includes a first endoscope channel 23 and a second endoscope channel 24 ; a plurality of second instrument channels 22 are provided on the outer wall of the second endoscope channel 24 , and a plurality of first instrument channels 21 corresponding to the second instrument channels 22 are slidably provided on the outer wall of the first endoscope channel 23 .
[0040] The surface of the inner tube 2 is designed with multiple first instrument channels 21 and second instrument channels 22, which are distributed around the two endoscope channels, so that the surgical instruments and the endoscope can work together. This design allows multiple surgical instruments to be used without interfering with each other, supports doctors to perform multiple treatments such as cutting, hemostasis, and suction in one operation, reduces the time for frequent instrument replacement, improves surgical efficiency, and reduces the risk of infection. The first instrument channel 21 is slidably connected to the first endoscope channel 23. Since the connection between the first instrument channel 21 and the rotating drum 11 is a curved surface, when the rotating drum 11 rotates, due to the effect of friction, the multiple first instrument channels 21 will also remain motionless, which will not affect the use of the instrument channels. The second instrument channel 22 is fixedly connected to the outer tube 1 and the second endoscope channel 24.
[0041] A rope 25 is connected to the rear end of the first instrument channel 21 , and the rope 25 passes through the second instrument channel 22 ; a spring 26 is provided between the first instrument channel 21 and the second instrument channel 22 , and an endoscope 7 is provided in the first endoscope channel 23 .
[0042] A rope 25 is arranged in the instrument channel, and the basic advance and retreat operation of the instrument can be realized by pushing and pulling the rope 25. At the same time, the spring 26 provides a rebound force, making the instrument smoother during the pushing and pulling process. The forward and backward movement of the instrument channel enables the doctor to accurately control the extension depth of the instrument, so as to adjust the position of the instrument without moving the entire endoscope, thereby contacting the diseased tissue more flexibly. This design is particularly suitable for the narrow anatomical structure of the digestive tract, and the doctor can operate in different depth ranges without frequently adjusting the position of the endoscope.
[0043] Embodiment 2: On the basis of the first embodiment, the second embodiment provides a specific structure of the pushing mechanism 5, as shown in the attached Figure 4-5 As described above, a plurality of pushing mechanisms 5 for adjusting the angle of the cleaning mechanism 6 are installed on the inner side wall of the rotating drum 11 .
[0044] The pushing mechanism 5 includes an electric push rod 51, a hydraulic channel 52, a telescopic rod 53 and a collar 54. The electric push rod 51 is installed on the inner surface of the drum 11, the electric push rod 51 is connected to the hydraulic channel 52, the hydraulic channel 52 is vertically connected to the telescopic rod 53, the telescopic rod 53 is movably connected to the collar 54, and the collar 54 is sleeved on the support rod 61. The telescopic rod 53 and the collar 54 are connected by a universal ball.
[0045] The pushing mechanism 5 controls the hydraulic channel 52 through the electric push rod 51 to realize the hydraulic driving of the telescopic rod 53, and further expands the support rod 61 through the linkage of the telescopic rod 53 and the collar 54. Since the telescopic rod 53 and the collar 54 are connected by a universal ball, the collar 54 will not get stuck due to the expansion of the support rod 61. At the same time, the support rod 61 and the turntable 41 are also connected by a universal ball, so that the support rod 61 can still rotate at an angle without getting stuck. This design enables the support rod 61 to provide a good support function during the operation, ensures a good operating field and operating space, reduces the surgical errors caused by insufficient support, and improves the safety and accuracy of the operation.
[0046] Specific application case: When a multifunctional digestive endoscopy treatment device is needed to treat a patient, a specific application method of a multifunctional digestive endoscopy treatment device of the present application is: The doctor inserts the endoscope device into the patient's digestive tract. The angle and direction of the endoscope are aligned with the surgical area through external regulation during the insertion process. After entering the surgical area, the push mechanism 5 is turned on. The push mechanism 5 controls the hydraulic channel 52 through the electric push rod 51 to realize the hydraulic drive of the telescopic rod 53. The support rod 61 is further extended through the linkage of the telescopic rod 53 and the collar 54. Since the telescopic rod 53 and the collar 54 are connected by a universal ball, the collar 54 will not get stuck due to the expansion of the support rod 61, ensuring the continuity and stability of cleaning. At the same time, the support rod 61 is also connected to the turntable 41 through a universal ball, so that the support rod 61 can still rotate at an angle without getting stuck. The universal ball connection avoids jamming during the expansion process and improves the support stability. Start the rotating mechanism 3, and the motor 33 drives the gear 32 to drive the rack 31 to move along the inner wall of the rotating cylinder 11, thereby driving the inner and outer tubes 1 to rotate. When the drum 11 starts to rotate, the rotation directly drives the support rod 61 and the cleaning head 62 to rotate. The cleaning head 62 starts to rotate due to the friction force. When the plane of the scraper 622 faces the tissue, it stops rotating due to the friction force. Under the action of the sponge pad 621, the surrounding blood or body fluids are cleaned to keep the surgical field clear. After the cleaning operation is completed, the rotating mechanism 3 is stopped. This design simplifies the cleaning steps during the operation, ensures the imaging effect, and facilitates the doctor's accurate operation.
[0047] The multiple first instrument channels 21 and second instrument channels 22 in the inner tube 2 allow different surgical instruments to be used simultaneously. The doctor controls the position of the first instrument channel 21 through the rope 25, and utilizes the push and pull of the rope 25 and the rebound force of the spring 26 to make the cutting process more flexible. The movable instrument channel allows the doctor to adjust the position of the cutter, and the forward and backward movement of the instrument channel enables the doctor to accurately control the telescopic depth of the instrument so as to adjust the position of the instrument without moving the entire endoscope, thereby more flexibly contacting the diseased tissue. This design is particularly suitable for the narrow anatomical structure of the digestive tract. The doctor can operate within different depth ranges without frequently adjusting the position of the endoscope. This design avoids interference between instruments and improves surgical efficiency.
[0048] During the tumor cutting process, if bleeding occurs, the doctor can insert a hemostatic forceps through another instrument channel to stop bleeding immediately while cutting. The doctor can also use an aspirator to promptly remove body fluids produced during the operation to keep the operation area clear and avoid obstruction of the field of vision. After the cutting and hemostasis operations, the doctor confirms that the tumor has been completely removed and the bleeding is under control, and finally withdraws the endoscope. The telescopic rod 53 in the pushing mechanism 5 is retracted to the initial position to ensure the safe withdrawal of the endoscope.
[0049] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
