Description

Technical Field

[0001] The present application relates to medical device technology, and in particular to a prostate hyperplasia cutting device. Background Art

[0002] Patients with prostatic hyperplasia suffer from urinary retention due to centripetal urethral obstruction, which may lead to secondary infection and affect the quality of life. In the late stage of hyperplasia, surgical removal of the hypertrophic prostate is often required to clear this section of the obstructed urethra.

[0003] Currently, surgical methods for prostate hyperplasia include transurethral resection of the prostate (transurethral plasma resection, plasma enucleation, transurethral holmium laser enucleation of the prostate, and transurethral green laser vaporization and enucleation), all of which require the use of a cystoscope to perform block-like resection under visualization. During the operation, flushing fluid must be used continuously to expose a good surgical field of view.

[0004] However, existing prostate hyperplasia surgery involves manually removing prostate hyperplasia tissue bit by bit under a cystoscope. The surgical efficiency is very low and the operation time is very long. Therefore, the flushing time of the flushing fluid is too long, and the continuous use of the flushing fluid is likely to cause a series of complications such as water intoxication, hyponatremia, hypothermia, etc. In addition, patients with prostate hyperplasia are often older and are more likely to induce perioperative cardiovascular and cerebrovascular accidents.

[0005] Therefore, the above-mentioned prior art has at least the following technical problems: prostate hyperplasia surgery has low surgical efficiency and long operation time, which leads to complications caused by continuous flushing with flushing fluid. Summary of the invention

[0006] The present application provides a prostate hyperplasia cutting device to solve the technical problem in the related art that prostate hyperplasia surgery is prone to complications due to low surgical efficiency and long surgical time, resulting in continuous flushing with flushing fluid.

[0007] In order to solve the above technical problems, the present application provides a prostate hyperplasia cutting device, comprising a support body, wherein a cutting part is provided in the support body, and the cutting part can automatically cut the prostate hyperplasia tissue to be cut;

[0008] The support body is also provided with a flushing pipeline and a negative pressure adsorption pipeline, wherein the output end of the flushing pipeline is close to the cutting part to provide flushing liquid to flush the cutting area;

[0009] The adsorption end of the negative pressure adsorption pipeline is close to the cutting part, and the mixture of the cut tissue and the flushing liquid in the cutting area is sucked out by negative pressure.

[0010] Furthermore, a groove is configured on the support body, and the cutting portion may be exposed or partially exposed in the groove to contact the prostate hyperplasia tissue to be cut and automatically cut.

[0011] Furthermore, the cutting part includes a cutting knife located in the slot, and the cutting knife is connected to a driving member for driving the cutting knife to move back and forth to perform a cutting action.

[0012] Furthermore, the cutting knife is connected to the driving member through a mechanical arm, and one end of the mechanical arm away from the cutting knife extends into the supporting body, and the mechanical arm is configured to drive the mechanical arm to perform a telescopic movement under the drive of the driving member, thereby driving the cutting knife to move back and forth to achieve cutting.

[0013] Furthermore, the support body can rotate circumferentially, thereby driving the cutting part, the flushing pipeline and the negative pressure adsorption pipeline to rotate synchronously to achieve rotary cutting.

[0014] Furthermore, a driving seat is installed at the rear end of the support body, and the driving seat can drive the support body to rotate circumferentially.

[0015] Furthermore, the output end of the flushing pipeline is located in the slot and is disposed close to the cutting knife; and / or the adsorption end of the negative pressure adsorption pipeline is located in the slot and is disposed close to the cutting knife.

[0016] Furthermore, the input end of the flushing pipeline is located on a side of the support body away from the cutting knife; and / or the negative pressure connection end of the negative pressure adsorption pipeline is located on a side of the support body away from the cutting knife.

[0017] Furthermore, the cutting device further comprises a monitoring component, which is arranged on a side of the slot facing away from the driving seat;

[0018] The monitoring component is configured to be able to penetrate into or out of the support body, so as to be extended out of the support body during surgery to monitor the cutting area, and to be retracted into the support body when not in use.

[0019] Furthermore, the monitoring component includes a camera, and the support body is provided with a through hole for the camera to pass into or out of the support body.

[0020] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0021] (1) The prostate hyperplasia cutting device described in the embodiment of the present application realizes an automated prostate tissue cutting process by providing a cutting part, a flushing pipeline, and a negative pressure adsorption pipeline combination. Since the cutting part automatically (i.e., electrically) cuts the prostate hyperplasia tissue, the cutting efficiency is greatly improved compared to manual cutting in the prior art, which is beneficial to improving surgical efficiency and shortening surgical time, thereby reducing the flushing time of the flushing fluid, avoiding problems such as water intoxication and hyponatremia caused by continuous flushing of the flushing fluid, effectively reducing the risk of surgical complications, and helping to shorten the postoperative recovery period.

[0022] (2) A driving seat is installed at the rear end of the support body, and the driving seat is used to drive the support body to rotate circumferentially around the driving seat.

[0023] The use of this rotary cutting device can quickly and accurately remove prostate hyperplasia tissue, reconstruct a patent urethra, shorten the operation time, and reduce the occurrence of adverse events caused by irrigation fluid absorption.

[0024] (3) The slot is a semi-open slot, and the cutting knife is still located in the circumferential protection space of the supporting body. Therefore, it can both allow the cutting knife to cut and prevent the cutting knife from accidentally injuring the human body when entering and exiting the human body.

[0025] (4) The prostate hyperplasia cutting device can realize all-round and real-time monitoring of the cutting area. In addition, the through-hole design on the supporting body allows the monitoring component to be stably exposed, providing medical personnel with a clear and accurate field of view, helping them to make timely adjustments during the operation, improving the cutting accuracy, and ensuring the safety of the operation. When the operation is not being performed, the monitoring component can be retracted into the supporting body through the through-hole, thereby reducing the cross-sectional size of the supporting body and facilitating the overall entry of the cutting device into the urethra and prostate.

[0029] The present application provides a prostate hyperplasia cutting device to solve the technical problem in the related art that prostate hyperplasia surgery is prone to complications due to low surgical efficiency and long surgical time, resulting in continuous flushing with flushing fluid.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] One or more embodiments of the present application provide a prostate hyperplasia cutting device, including a support body 100, wherein a cutting portion is provided in the support body 100, and the cutting portion can automatically cut the prostate hyperplasia tissue to be cut; the support body 100 is also provided with a flushing pipeline 102 and a negative pressure adsorption pipeline 103, wherein the output end 1021 of the flushing pipeline 102 is close to the cutting portion to flush the cutting area, and can provide flushing liquid mixed with crushed tissue (i.e., the cut prostate hyperplasia tissue), and can cool the cutting area to prevent high temperature burns; the negative pressure adsorption pipeline 103 is arranged in the support body 100, and the adsorption end 1031 of the negative pressure adsorption pipeline 103 is close to the cutting portion, and the mixture of flushing liquid and cut prostate hyperplasia tissue in the cutting area is sucked out by negative pressure.

[0032] From the above description, it can be seen that the prostate hyperplasia cutting device described in the embodiment of the present application realizes the automated cutting process of prostate tissue by setting a cutting part, a flushing pipeline, and a negative pressure adsorption pipeline combination. Since the cutting part automatically cuts the prostate hyperplasia tissue, compared with the manual cutting in the prior art, the cutting efficiency is greatly improved, which is beneficial to improving the surgical efficiency and shortening the operation time, thereby reducing the flushing time of the flushing fluid, avoiding the problems of water intoxication, hyponatremia, etc. caused by continuous flushing of the flushing fluid in the related technology, effectively reducing the risk of surgical complications, and helping to shorten the postoperative recovery period.

[0033] like Figure 1As shown, in the embodiment of the present application, the support body 100 is a cylindrical tube, and the interior of the support body 100 is hollow, which is used to install various pipelines and harness components. Based on the direction of the cutting device in the use state (i.e., the end facing the patient is the front end, and the end facing the surgeon is the rear end), a slot 105 is constructed on one side of the outer wall of the support body 100, and the cutting part includes a cutting knife 1061 exposed in the slot 105, and a mechanical arm 1062 connected to the cutting knife 1061, and the end of the mechanical arm 1062 away from the cutting knife 1061 (i.e., the rear end) extends into the support body 100, and the mechanical arm 1062 is configured to drive the cutting knife 1061 to move back and forth under the drive of the driving member 1063, so as to cut the prostate hyperplasia tissue to be cut.

[0034] The slot 105 in the above embodiment is a semi-open slot extending along the axial direction of the support body 100, wherein the mechanical arm 1062 can be telescopically displaced along the axial direction of the support body 100, and the mechanical arm 1062 can be driven to displace by a linear drive component.

[0035] By arranging a slot 105 on the support body 100 and combining the design of the robotic arm 1062 and the cutting knife 1061, the prostate hyperplasia cutting device can achieve a more stable, accurate and flexible cutting process. The driving displacement of the robotic arm 1062 ensures the automatic, efficient and precise operation of the cutting knife 1061, making the operation more efficient and convenient, and reducing the risk of misoperation; in addition, the slot 105 is a semi-open slot (for example, the central angle of the slot 105 does not exceed 180°), and the cutting knife is still located in the circumferential protection space of the support body 100. Therefore, it can allow the cutting knife 1061 to cut, and prevent the cutting knife 1061 from accidentally injuring the human body during the process of entering and exiting the human body.

[0036] Here, the supporting body 100 in the embodiment of the present application is equipped with a driving member 1063, and the driving end of the driving member 1063 is connected to the mechanical arm 1062 to drive the mechanical arm 1062 to perform a telescopic action, thereby driving the cutting knife 1061 to move back and forth to perform cutting. The driving member 1063 can be a linear motor, which will not be described in detail in the embodiment of the present application.

[0037] In addition, in the embodiment of the present application, the cutting knife 1061 is a laser knife. The specific structure of the laser knife can refer to the components of the laser cutting scalpel in medical equipment, and the implementation of this application will not be repeated.

[0038] Furthermore, a driving seat 104 is installed at the rear end of the support body 100, and the driving seat 104 is used to drive the support body 100 to rotate circumferentially around the driving seat. Since the cutting part, the flushing pipeline 102 and the negative pressure adsorption pipeline 103 are all arranged in the support body 100, the driving seat 104 drives the support body 100 to rotate circumferentially, so that the cutting device can rotate, and the cutting part can cut the prostate tissue from different circumferential angles, which is convenient for medical personnel to adjust the cutting direction of the cutting part to better adapt to the morphology and cutting requirements of the prostate tissue, making the cutting process more uniform and accurate, and reducing tissue damage and trauma caused by improper operation.

[0039] For example, the driving seat 104 may include a rotary motor in the prior art.

[0040] like Figure 2 As shown, in the embodiment of the present application, a monitoring component 101 is further provided near the front end of the support body 100. The monitoring component 101 is provided in the support body 100 and is configured to be exposed outside the support body 100 under the drive of an external force to monitor the cutting area of ​​the cutting part. The monitoring component can detect the cutting area in real time to ensure the cutting position and cutting depth of the cutting part, thereby facilitating the staff to grasp the cutting accuracy and avoid accidental cutting of surrounding tissues.

[0041] The monitoring component 101 is arranged on the side of the slot 105 away from the driving seat 104 (i.e., arranged at the front end of the slot), and the monitoring component 101 is configured to be able to penetrate into or out of the supporting body 100 along the radial direction of the supporting body 100, so as to extend out of the supporting body 100 during surgery to monitor the cutting area, and to be retracted into the supporting body 100 when not in use, so as to facilitate entering and exiting the human body. Here, the monitoring component 101 can adopt a medical camera in the related art, and a through hole 107 for the monitoring component 101 to extend is provided on the supporting body 100.

[0042] For example, in one embodiment of the present application, a linear drive motor is provided in the support body 100, and the driving end of the linear drive motor is connected to the monitoring component 101, thereby driving the monitoring component 101 to perform telescopic displacement along the radial direction of the support body. Of course, the driving of the aforementioned cutting knife 1061, the driving of the monitoring component 101, and the driving of the driving seat 104 can all be connected to an external control device through a wire harness, or wirelessly connected. This part of the connection can refer to the connection method in the relevant technology, and will not be repeated in the embodiment of the present application.

[0043] The prostate hyperplasia cutting device can realize all-round and real-time monitoring of the cutting area. In addition, the through hole 107 on the support body 100 allows the monitoring component 101 to be stably exposed, providing a clear and accurate field of view for medical personnel, helping them to make timely adjustments during the operation, improving the cutting accuracy, and ensuring the safety of the operation. When the operation is not being performed, the monitoring component 101 can be retracted into the support body 100 through the through hole 107, thereby reducing the cross-sectional size of the support body 100 and facilitating the cutting device to enter the urethra and prostate as a whole.

[0044] like Figure 2 As shown, in an embodiment of the present application, the output end 1021 of the flushing pipeline 102 is located in the slot 105 and is arranged close to the cutting knife 1061; and / or, the adsorption end 1031 of the negative pressure adsorption pipeline 103 is located in the slot 105 and is arranged close to the cutting knife 1061.

[0045] Furthermore, the output end 1021 and the adsorption end 1031 are both located in the slot 105 and are arranged close to the cutting knife 1061. This design ensures that the cutting area is always kept clean to avoid the accumulation of impurities that affect the field of vision and operation. Under the synergistic effect of the flushing pipeline 102 and the negative pressure adsorption pipeline 103, the flushing and adsorption pipelines not only improve the surgical efficiency and accuracy, but also effectively reduce the risks of intraoperative bleeding, swelling and infection.

[0046] As an alternative embodiment, the input end 1022 of the flushing pipeline 102 is located on the side of the support body 100 away from the cutting knife 1061; and / or, the negative pressure connection end 1032 of the negative pressure adsorption pipeline 103 is located on the side of the support body 100 away from the cutting knife 1061.

[0047] Furthermore, the input end 1022 and the negative pressure connection end 1032 are both located on the side of the support body 100 away from the cutting knife 1061. Since the output end 1021 and the adsorption end 1031 are close to the cutting knife 1061, and the input end 1022 and the negative pressure connection end 1032 are located on the side of the support body 100 away from the cutting knife 1061, the pipeline located in the support body 100 can be arranged along the axial direction of the support body, optimizing the flow path of the liquid and the negative pressure airflow, and avoiding liquid accumulation or reflux problems.

[0048] In addition, the input end 1022 of the flushing pipeline 102 is connected to a flushing water source (eg, a water tank containing flushing liquid), and the negative pressure connection end 1032 of the negative pressure adsorption pipeline 103 is connected to a negative pressure source.

[0049] An exemplary use process of a prostate hyperplasia cutting device described in the embodiment of the present application is as follows:

[0050] Before the operation, magnetic navigation is established to determine the cutting path. According to the cutting path, the movement path and parameters of the laser knife are determined. After anesthesia, the support body 100 passes through the urethra and prostate until the front end enters the bladder, and the slot 105 is aligned with the prostate. The linear drive motor drives the camera through the through hole 107 in the tube wall to the outside of the support body 100 to monitor the cutting area.

[0051] Start the laser knife system. Driven by the robot arm 1062, the laser knife operates according to the planned motion path and parameters to cut and crush the prostate hyperplasia tissue. The flushing pipeline 102 supplies water at the same time, which on the one hand mixes the crushed tissue, and on the other hand cools it down to prevent high temperature burns. The negative pressure adsorption pipeline 103 absorbs the mixed flushing liquid and tissue. After the cutting at one angle is completed, the support body 100 rotates relatively under the action of the drive seat 104, and cuts the prostate tissue from another circumferential angle until all circumferential tissue cutting is completed.

[0052] The camera monitors the whole process, and immediately stops the system if any accident is found. After the operation is completed, the camera returns to the support body 100, and the cutting device is withdrawn from the human body as a whole.

These terms are used only to distinguish one unit from another. For example, a first unit may be referred to as a second unit, and similarly, a second unit may be referred to as a first unit without departing from the scope of the exemplary embodiments.
