Description

Technical Field

[0001] The present invention relates to the technical field related to anorectal medical treatment, and in particular to an anorectal minimally invasive rotary cutting endoscope. Background Art

[0002] Anorectal medicine is a branch of medicine that specializes in the diagnosis, treatment and prevention of diseases in the anus and rectum. The scope of anorectal diseases includes anorectal surgical diseases and anorectal internal medicine diseases. Anorectal surgical diseases include hemorrhoids, anal fistulas, anal fissures and perianal abscesses, and anorectal internal medicine diseases include proctitis and colitis. The main treatment methods are drug therapy, surgical treatment and physical therapy. Drug therapy includes: topical medications and oral medications. Surgical treatment includes: hemorrhoidectomy, anal fistula incision or hanging thread therapy and anal fissure surgery. Physical therapy includes: sitz bath, laser therapy and cryotherapy. In traditional anorectal surgery, doctors mainly rely on tools such as anoscope for observation. However, the field of view of the anoscope is limited. It is difficult to achieve comprehensive and clear observation of some lesions that are located deeper or at tricky angles. Therefore, there is a special need for an anorectal minimally invasive rotary cutting endoscope.

[0003] However, during use, existing minimally invasive anorectal rotary cutting endoscopes cannot examine tissues and organs deeper inside the human body due to the limited length of the endoscope, making it impossible for doctors to accurately judge the severity of the disease and the nature of the lesion. This may lead to misdiagnosis or missed diagnosis, delaying the patient's best treatment time and further worsening the condition. At the same time, after frequent use of the rotary cutting knife, the rotary cutting knife head may wear out, affecting the cutting effect, and the existing maintenance and replacement of parts are relatively complex and expensive, which increases the cost of using the instrument. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the anorectal minimally invasive rotary cutting endoscope, through the setting of the rotating telescopic mechanism and the installation limit mechanism, when it is necessary to adjust the telescopic position of the rotary cutting knife and the probe, the motor in the motor housing is started, and the motor drives the threaded rod to rotate. Since the telescopic block is threadedly connected to the threaded rod, under the action of the thread, the telescopic block will move axially along the threaded rod. At the same time, the telescopic rod connected to the telescopic block will also move telescopically smoothly in the telescopic groove, thereby driving the probe installed on the outside of the telescopic rod to achieve telescoping, so as to penetrate into or exit different depths inside the anorectal, which is convenient for exploring tissues at different positions. When the rotary cutting operation is required, the motor drives the rotating rod to rotate at high speed, and the rotating rod fixed on the rotary The rotary cutter at one end of the rotating rod also rotates synchronously. During the rotation of the rotary cutter, the micro-light on its outer side provides lighting, so that the doctor can clearly observe the situation of the rotary cutter through the display screen. According to the observation results, the doctor can combine the control of the operation key to accurately adjust the position and rotation speed of the rotary cutter to accurately cut the diseased tissue in the anorectal. For example, for internal hemorrhoid tissue, the rotary cutter can be extended to the appropriate position and then started to rotate to gradually remove the hemorrhoids; for rectal polyps, they can also be completely removed through precise manipulation. The card slot at one end of the rotating rod cooperates with the card block of the rotary cutter to ensure the stability of the rotary cutter during high-speed rotation, prevent it from loosening or displacement, and ensure the safety and accuracy of the operation. The endoscope holder on the handle can facilitate the doctor to properly place and fix the instrument during the operation, reducing the operational error caused by unstable hand-holding. When the rotary cutter needs to be installed, align the card block with the card slot and push it in slowly. During this process, the connecting block drives the fixing rod to move synchronously, and the limit rod in the fixing rod slides along the slide groove, and the limit block at its bottom moves smoothly in the limit groove, which ensures that the card block can accurately enter the card slot along the predetermined path. When the card block completely enters the card slot, the elastic force generated by the displacement of the telescopic spring that was originally in a compressed state is released, pushing the limit rod toward the inner wall of the card slot until the limit rod is accurately inserted into the limit hole, thereby firmly locking the card block in the card slot. A stable connection between the components and the rotating and telescopic mechanism is achieved. This connection method ensures that the relevant components will not easily loosen or move during the operation of the instrument, even if they are subjected to various external forces in the complex environment inside the anorectal cavity, such as squeezing and friction caused by intestinal peristalsis. This effectively ensures that the endoscope can work stably and accurately during minimally invasive anorectal rotary cutting surgery. Moreover, when the rotary cutting knife is worn and needs to be disassembled and replaced, it is only necessary to apply inward pressure to the fixed block to overcome the elastic force of the telescopic spring and withdraw the limit rod from the limit hole, so that the card block can be smoothly pulled out of the card slot. The operation is simple and quick, which greatly improves the maintenance efficiency and flexibility of the instrument and can better adapt to different surgical needs and instrument maintenance requirements.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-8The present invention provides a technical solution: an anorectal minimally invasive rotary resection endoscope, comprising a display 1, an operation key 2 connected to the surface of the display 1, a display screen 3 provided on the surface of the display 1, an output line 4 connected to one side of the display 1, an extension line 5 provided at one end of the output line 4, a rotating telescopic mechanism 6 provided at one end of the extension line 5, an installation limit mechanism 7 provided inside the rotating telescopic mechanism 6, and a buffer mechanism 8 provided at the bottom of the rotating telescopic mechanism 6;

[0027] The installation limit mechanism 7 includes a slot 701, a block 702, a connecting block 703, a fixed rod 704, a slide 705, a limit slot 706, a limit rod 707, a limit block 708, a telescopic spring 709, a fixed block 710 and a limit hole 711. The interior of the rotating and telescopic mechanism 6 is provided with a slot 701, the surface of the rotating and telescopic mechanism 6 is provided with a block 702, one end of the block 702 is fixedly connected to the connecting block 703, the surface of the connecting block 703 is fixedly connected to the fixing rod 704, the interior of the fixing rod 704 is provided with a slide 705, and limiting slots 706 are provided on both sides of the slide 705. The interior of the slide 705 slides The limit rod 707 is dynamically connected, and the bottom surface of the limit rod 707 is fixedly connected to the limit block 708. The outer end of the limit rod 707 is wound with a telescopic spring 709. One end of the limit rod 707 and the telescopic spring 709 are fixedly connected to a fixing block 710. The inner wall of the slot 701 is provided with a limit hole 711. By installing the setting of the limit mechanism 7, when the rotary cutter 610 needs to be installed, the block 702 is aligned with the slot 701 and slowly pushed in. In this process, the connecting block 703 drives the fixing rod 704 to move synchronously, and the limit rod 707 in the fixing rod 704 slides along the slide groove 705, and the limit block 708 at the bottom thereof is in the limit hole 711. After the locking nut 706 is locked, the locking nut 702 is locked and the locking nut 706 is locked. Various external forces in the environment, such as squeezing and friction caused by intestinal peristalsis, will not easily loosen or move, which effectively ensures that the endoscope can work stably and accurately in anorectal minimally invasive rotary cutting surgery. Moreover, when the rotary cutting knife 610 is worn and needs to be disassembled and replaced, it is only necessary to apply inward pressure to the fixed block 710 to overcome the elastic force of the telescopic spring 709 and withdraw the limit rod 707 from the limit hole 711, so that the card block 702 can be smoothly pulled out of the card slot 701. The operation is simple and quick, which greatly improves the maintenance efficiency and flexibility of the instrument and can better adapt to different surgical needs and instrument maintenance requirements.

[0028] Furthermore, the rotating telescopic mechanism 6 includes a motor housing 601, a handle 602, a motor 603, a telescopic slot 604, a threaded rod 605, a rotating rod 606, a telescopic block 607, a telescopic rod 608, a limit plate 609, a rotary cutter 610, a probe 611 and a miniature lighting lamp 612. One end of the extension line 5 is fixedly connected to the motor housing 601, one end of the motor housing 601 is fixedly connected to the handle 602, the inside of the motor housing 601 is fixedly connected to the motor 603, the inside of the handle 602 is provided with a telescopic slot 604, one end of the motor 603 is fixedly connected to the threaded rod 605, one end of the motor 603 is fixedly connected to the rotating rod 606, the outer wall surface of the threaded rod 605 is threadedly connected to the telescopic block 607, and the outer wall of the telescopic block 607 is fixedly connected to the outer wall of the telescopic block 607. A telescopic rod 608 is fixedly connected to the wall surface, the end of the threaded rod 605 is fixedly connected to a limit plate 609, one end of the rotating rod 606 is fixedly connected to a peeling knife 610, a probe 611 is installed on the outside of the telescopic rod 608, a miniature lighting lamp 612 is installed on the outside of the peeling knife 610, a card slot 701 is opened inside one end of the rotating rod 606, one end of the peeling knife 610 is fixedly connected to a card block 702, and an endoscope fixing frame 801 is provided on the outer wall surface of the handle 602. By rotating the setting of the telescopic mechanism 6, when it is necessary to adjust the telescopic position of the peeling knife 610 and the probe 611, the motor 603 in the motor housing 601 is started, and the motor 603 drives the threaded rod 605 to rotate. Since the telescopic block 607 is threaded with the threaded rod 605, the endoscope fixing frame 801 is provided. The telescopic block 607 is connected to the anorectal tube 605, and the telescopic rod 608 connected to the telescopic block 607 moves axially along the threaded rod 605. At the same time, the telescopic rod 608 connected to the telescopic block 607 also moves smoothly in the telescopic groove 604, thereby driving the probe 611 installed on the outside of the telescopic rod 608 to extend and retract, so as to penetrate or exit different depths inside the anorectal tube, which is convenient for exploring tissues at different positions. When the rotary cutting operation is required, the motor 603 drives the rotating rod 606 to rotate at a high speed, and the rotary cutter 610 fixed at one end of the rotating rod 606 also rotates synchronously. During the rotation of the rotary cutter 610, the micro-illuminator 612 on its outside provides lighting, so that the doctor can clearly observe the situation of the rotary cutter through the display screen 3. The doctor can According to the observation results, combined with the control of the operation key 2, the position and rotation speed of the rotary cutter 610 are accurately adjusted to accurately cut the diseased tissue in the anorectal area. For example, for internal hemorrhoidal tissue, the rotary cutter 610 can be extended to the appropriate position and then started to rotate to gradually remove the hemorrhoids; even for rectal polyps, they can be completely removed through precise manipulation. The slot 701 at one end of the rotating rod 606 cooperates with the block 702 of the rotary cutter 610 to ensure the stability of the rotary cutter 610 during high-speed rotation, prevent it from loosening or displacement, and ensure the safety and accuracy of the operation. The endoscope fixing frame 801 on the handle 602 can facilitate the doctor to properly place and fix the instrument during the operation, reducing operational errors caused by unstable handholding.

[0029] Furthermore, the outer wall surface of the handle 602 is provided with multiple groups of anti-slip grooves, and the depth of the anti-slip grooves is not less than 0.3 mm. Through the setting of the handle 602, the outer wall of the handle 602 is provided with multiple groups of anti-slip grooves with a depth of not less than 0.3 mm, which is of great significance in anorectal surgery. During the operation, the doctor's hands may become wet and slippery due to sweat, residual disinfectant liquid or long-term operation. This anti-slip groove can greatly enhance the friction between the handle and the doctor's hand, making the doctor more stable when holding it.

[0030] Furthermore, the rotating rod 606 rotates inside the threaded rod 605, and the two do not intersect. Through the arrangement of the threaded rod 605 and the rotating rod 606, the rotating rod 606 rotates inside the threaded rod 605 and the two do not intersect, thereby ensuring the structural stability and functional independence of the instrument. The rotating rod 606 is responsible for driving the rotary cutter 610 to perform rotary cutting, while the threaded rod 605 mainly controls the extension and retraction of the telescopic block 607 and related components. The non-interference operation of the two allows the rotary cut and telescopic functions to be precisely and independently regulated. During surgery, the doctor can first accurately extend and retract the rotary cutter 610 and the probe 611 to the appropriate position through the threaded rod 605 according to the location and shape of the diseased tissue, and then start the rotating rod 606 to perform the rotary cut operation, thereby avoiding operational errors caused by structural interference, improving the safety and effectiveness of the surgery, and also helping to extend the service life of the instrument and reduce the probability of failure.

[0031] Furthermore, there are multiple groups of probes 611 evenly spaced on the surface of the telescopic rod 608, and multiple groups of micro-lights 612 are set on the surface of the rotary cutter 610. Through the setting of the probes 611 and the micro-lights 612, the multiple groups of probes 611 evenly spaced on the surface of the telescopic rod 608 can detect the internal tissues of the anorectal from different angles and positions, providing more comprehensive and detailed tissue information. When examining intestinal lesions, probes at different positions can detect a wider area, reducing the possibility of missing lesions. At the same time, the setting of multiple groups of micro-lights 612 on the surface of the rotary cutter 610 provides sufficient and uniform lighting for surgical operations. In the relatively dark and narrow environment inside the anorectal, the clear lighting allows the doctor to accurately observe the relative position relationship between the rotary cutter 610 and the diseased tissue through the display screen 3, making the rotary cutting operation more precise, avoiding accidental cutting of healthy tissue, improving the effect of surgical treatment, and reducing the risk of postoperative complications.

[0032] Furthermore, the position of the block 702 corresponds to the position of the slot 701, and the outer wall size of the block 702 matches the inner wall size of the slot 701. Through the arrangement of the slot 701 and the block 702, the design of the block 702 corresponding to the position of the slot 701 and matching the size plays a key positioning and fixing role in the installation process of the rotary cutter 610 and other components. When the rotary cutter 610 is installed, the block 702 is accurately inserted into the slot 701, so that the rotary cutter 610 and the rotating rod 606 are tightly and stably connected. This connection method ensures that the rotary cutter 610 will not loosen or deviate during high-speed rotation, ensuring the accuracy and safety of the rotary cutting action. In anorectal surgery, a stable rotary cutter 610 is crucial for accurately removing diseased tissue, and can effectively prevent unnecessary damage to surrounding tissues due to tool shaking, improve surgical quality, and ensure the safety and recovery effect of patients.

[0033] Furthermore, the position of the limit block 708 corresponds to the position of the limit slot 706, and the outer wall size of the limit block 708 is consistent with the inner wall size of the limit slot 706. Through the setting of the limit slot 706 and the limit block 708, the limit block 708 corresponds to the position of the limit slot 706 and the size is consistent, which plays a precise guiding and stabilizing role in the process of the connecting block 703 driving the fixing rod 704 to move. When the block 702 is inserted into the slot 701, the limit rod 707 in the fixing rod 704 moves accordingly, and the limit block 708 slides in the limit slot 706, limiting the other degrees of freedom of the fixing rod 704 except the predetermined direction, so that the block 702 can be smoothly inserted into the slot 701 along the correct path. This not only improves the convenience and accuracy of component installation, but also prevents the fixing rod 704 and related components from being displaced or deformed even if subjected to external force or vibration during operation of the instrument, thereby ensuring the stability of the installation structure and ensuring that the endoscope can operate reliably in a complex anorectal surgical environment.

[0034] Furthermore, the position of the fixing block 710 corresponds to the position of the limiting hole 711, and the outer wall size of the fixing block 710 matches the inner wall size of the limiting hole 711. Through the setting of the fixing block 710 and the limiting hole 711, the design of the corresponding position and matching size of the fixing block 710 and the limiting hole 711 realizes the effective locking of the card block 702 in the card slot 701. When the card block 702 is installed in place, the telescopic spring 709 pushes the limiting rod 707 to drive the fixing block 710 to be inserted into the limiting hole 711, and firmly fixes the card block 702 in the card slot 701. This locking mechanism can withstand various complex external forces during surgery, such as the extrusion force generated by intestinal peristalsis and the centrifugal force when the rotary cutter 610 rotates, thereby preventing the rotary cutter 610 from accidentally falling off, ensuring the continuity and safety of the surgery, avoiding interruption of the surgery or serious medical accidents due to loose components, and effectively protecting the patient's surgical safety and treatment effect.

[0035] Furthermore, the buffer mechanism 8 includes an endoscope fixing frame 801, a buffer plate 802, a buffer rod 803, a buffer spring 804, an adjustable bracket 805 and a base 806. The surface of the rotating and telescopic mechanism 6 is provided with an endoscope fixing frame 801, the bottom of the endoscope fixing frame 801 is fixedly connected with the buffer plate 802, the bottom of the buffer plate 802 is fixedly connected with the buffer rod 803, the outer side of the buffer rod 803 is wrapped with a buffer spring 804, the outer wall surface of the buffer rod 803 is slidably connected with the adjustable bracket 805, the bottom of the adjustable bracket 805 is fixedly connected with the base 806, and the other end of the buffer spring 804 is fixedly connected to the top of the adjustable bracket 805. Through the setting of the buffer mechanism 8, when the anorectal minimally invasive rotary cutting endoscope is subjected to external impact or vibration, such as during the surgical operation due to sudden movement of the patient's body, the instrument colliding with surrounding objects, etc., the buffer plate 802 first receives the external force, and the buffer plate 802 will transmit the force to the buffer rod 803, and the buffer rod 803 moves along the adjustable support The inner wall of the bracket 805 slides downward. At this time, the buffer spring 804 wrapped around the outside of the buffer rod 803 is compressed, and the buffer spring 804 will generate an elastic force in the opposite direction of the external force. This elastic force will gradually offset the effect of the external force, thereby slowing down the sliding speed of the buffer rod 803, and then reducing the impact force transmitted to the instrument body. The adjustable bracket 805 and the base 806 provide a stable support foundation for the entire buffer structure, and the adjustable characteristics of the adjustable bracket 805 can adjust the height and angle and other parameters of the buffer mechanism 8 according to actual use needs to adapt to different surgical environments and operation requirements. The elastic deformation of the buffer spring 804 is used to absorb and disperse the impact force, effectively protecting the internal precision components of the endoscope, such as the motor 603, probe 611, and rotary cutter 610, to avoid damage, loosening or reduced accuracy of components due to severe impact or vibration, ensuring that the endoscope can operate stably and reliably under various complex usage conditions, and ensuring the smooth progress of the operation and the accuracy of the surgical results.

[0036] Working principle: First, the doctor starts the device and performs the initial settings of various functions by operating the operation key 2 on the surface of the display 1. When an examination or surgical operation is required, if the position of the rotary cutter 610 and the probe 611 is adjusted to penetrate into different depth areas inside the anorectal cavity, the motor 603 in the motor housing 601 is started, driving the threaded rod 605 to rotate, so that the telescopic block 607 threadedly connected thereto moves along the axial direction of the threaded rod 605, thereby driving the telescopic rod 608 to smoothly extend and retract in the telescopic slot 604, realizing the telescopic movement of the probe 611. Multiple groups of probes 611 distributed at equal intervals on the telescopic rod 608 are used to measure the anorectal tissue from different angles. The anorectal tissue is detected and the tissue information is transmitted to the display screen 3 of the display 1 through the extension line 5 and the output line 4 to be presented to the doctor. At the same time, the rotary cutter 610 is also moved to the vicinity of the target position. The multiple groups of miniature lighting lamps 612 on the outside provide sufficient and uniform lighting for the surgical area so that the doctor can clearly observe the relative position of the rotary cutter 610 and the tissue. After the position is determined, if the rotary cut operation is to be performed, the motor 603 drives the rotating rod 606 to rotate at a high speed, driving the rotary cutter 610 which is fixed at one end thereof and is precisely connected to the card slot 701 at one end of the rotating rod 606 through the card block 702 and is locked by the fixed block 710 and the limiting hole 711. 0 synchronous rotation, the doctor accurately controls the position and rotation speed of the rotary cutter 610 according to the observation results on the display screen 3 and the operation key 2, and accurately cuts the diseased tissue. During the whole process, the rotating rod 606 rotates independently inside the threaded rod 605 without interfering with each other, ensuring the precise control of the rotary cutting and telescopic functions. During the operation, if the patient's body moves suddenly or the instrument collides with surrounding objects to generate external impact or vibration, the buffer mechanism 8 will play a role, and the buffer plate 802 receives the external force and transmits it to the buffer rod 803. The buffer rod 803 slides down along the inner wall of the adjustable bracket 805 and compresses the buffer spring 804, and the buffer spring 804 generates a reverse elastic force To offset external forces, slow down the sliding speed of the buffer rod 803, and reduce the impact force on the instrument body, the adjustable bracket 805 and the base 806 provide stable support and the height and angle and other parameters of the buffer mechanism 8 can be adjusted according to needs, effectively protecting the motor 603, probe 611, rotary cutter 610 and other internal precision components, ensuring the stable and reliable operation of the endoscope, ensuring the smooth progress of the operation and accurate results, and the doctor can successfully complete the inspection and treatment of anorectal diseases, providing effective medical support for the patient's anorectal health. Among them, the model of motor 603 is Y315S-2, thus completing the use process of an anorectal minimally invasive rotary cut endoscope.
