Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to a seminal vesiculoscope. BACKGROUND

[0002] The seminal vesiculoscope surgery is an important minimally invasive means for treating male reproductive system diseases such as hematospermia and seminal vesicle calculi. In the prior art, there is a visible dilatation seminal vesiculoscope assembly disclosed in CN116035519A, which realizes visualized entry through a dilatation sheath with a visible channel, and utilizes a series of dilatation sheaths with different sizes to gradually dilate the ejaculatory duct. However, the technology has the following deficiencies: first, its treatment function mainly depends on the subsequent seminal vesiculoscope carrying surgical instruments (such as a lithotripsy optical fiber) for flushing or lithotripsy, and lacks direct and effective hemostasis means for the root cause of hematospermia, i.e. abnormal blood vessels bleeding in the seminal vesicle; second, the head end of the dilatation sheath is flat or conical to facilitate picking up the ejaculatory duct opening, but the structure is fixed, and the sharp edge of the above head end has the risk of scratching the duct wall when passing through the fragile and hidden ejaculatory duct.

[0003] Therefore, there is an urgent need in the art for a seminal vesiculoscope device that can safely enter the ejaculatory duct and accurately and minimally invasively treat the bleeding points inside the seminal vesicle. SUMMARY

[0004] The prior art has the above deficiencies, and the present application is proposed to solve the following technical problems:

[0005] How to provide a seminal vesiculoscope device that can electrocoagulate and stop bleeding of the abnormal blood vessels in the seminal vesicle, thereby effectively treating hematospermia. How to overcome the defect of the single function of the head end of the existing seminal vesiculoscope or dilatation sheath, so that it can effectively pick up the hidden ejaculatory duct opening and prevent damage to the ejaculatory duct during entry and operation.

[0006] The present application specifically provides the following technical solutions: a seminal vesiculoscope, comprising: a seminal vesiculoscope main body, the seminal vesiculoscope main body having an execution end and an operation end, the execution end being provided with a lens and an illumination element. The seminal vesiculoscope further comprises:

[0007] an electrode, partially penetrating the seminal vesiculoscope main body and extending out of the execution end, the electrode being connected to a power source through a lead wire, and the electrified electrode electrocoagulating and stopping bleeding of the abnormal blood vessels;

[0008] The guide sheath is sleeved on the outer wall of the seminal vesiculoscope body, and has a connecting end and a deformed end. The connecting end is connected with the seminal vesiculoscope body to limit the relative movement between the guide sheath and the seminal vesiculoscope body. The connecting end is connected with the seminal vesiculoscope body in a bolted manner. A cavity is arranged between the inner wall and the outer wall of the guide sheath. The deformed end is provided with a slope, and the cavity is open to the slope. An elastic membrane is arranged between the deformed end and the cavity. When the elastic membrane is in a natural state, the deformed end is shovel-shaped and used for picking up the ejaculatory duct orifice. During the deformation of the elastic membrane to the outside of the slope, the deformed end is deformed from the shovel shape to the cylindrical shape.

[0009] Further, the outer wall of the connecting end is provided with a gas pressure interface. A connecting channel is arranged between the outer wall and the inner wall of the guide sheath. The connecting channel communicates the cavity and the gas pressure interface. When the gas flow moves to the cavity through the gas pressure interface, the elastic membrane is driven to be separated from the natural state. By arranging the gas pressure interface connected with the cavity, the gas flow is pushed to the cavity at the connecting end of the guide sheath left in the body, so that the deformation state of the elastic flap can be changed, and the deformed end can be switched between the two shapes.

[0010] Further, the perpendicular line of the slope and the central axis of the guide sheath form an acute angle with the tip towards the connecting end. The number of slopes is two, and the two slopes are equally spaced and arranged in a circular array around the central axis of the guide sheath, so that the deformed end is shovel-shaped. The cavity is arranged along the central axis of the guide sheath. A cylinder piston is sleeved in the cavity. When the cylinder piston is in an initial position, the elastic membrane is in a natural state. During the movement of the cylinder piston to the deformed end along the central axis of the guide sheath, the elastic membrane is expanded radially along the central axis of the guide sheath, so that the outer wall of the elastic membrane is flush with the outer wall of the guide sheath. When the cylinder piston moves to abut against the inner wall of the cavity, the slope is expanded outward by the cylinder piston, so that the deformed end is deformed from the shovel shape to the cylindrical shape.

[0011] Further, the gas pressure interface is provided with a slider piston and an elastic member. The two ends of the elastic member are connected with the inner wall of the gas pressure interface and the slider piston, respectively. When the elastic member is in a natural state, the elastic membrane is also in a natural state. When the slider piston moves to the inner wall of the guide sheath, the elastic member is extruded, and the gas flow in the gas pressure interface moves to the cavity, so that the elastic membrane is deformed from the natural state. By arranging the slider piston slidingly connected in the gas pressure interface and the cylinder piston slidingly connected in the cavity, the space between the gas pressure interface and the cavity is dynamically sealed, so that the movement of the cylinder piston in the cavity can be controlled by moving the depth of the slider piston in the gas pressure interface, so as to indirectly realize the deformation control of the deformed end.

[0012] Further, the air pressure interface is bolted with a knob, the knob is in contact with the slider piston towards the end of the guide sheath; when the knob rotates around its own central axis and moves towards the air pressure interface, the slider piston is extruded, so that the deformed end is deformed from shovel shape to cylindrical shape.

[0013] Further, the seminal vesiculoscope body comprises a pipeline communication cavity and a mirror tube which are in communication with each other; the deformed end and the connecting end of the guide sheath further have a sheath tube, the outer wall of the connecting end is provided with a communication valve one; the sheath tube is sleeved outside the mirror tube, and the inner diameter of the sheath tube is greater than the outer diameter of the mirror tube; when the communication valve one is open and the guide sheath enters the ejaculatory duct, the two sides of the communication valve one form a fluid suction and perfusion passage. When the communication valve one is closed, the suction and perfusion passages are sealed.

[0014] Further, the inside of the seminal vesiculoscope body is provided with an insulation channel, one end of the insulation channel is opened at the execution end, the other end of the insulation channel extends out of the outer wall of the pipeline communication cavity, and a lead wire electrically connected with an electrode is arranged in the insulation channel. When the electrode contacts the wound and the lead wire is electrified, the current passes through the surrounding tissue of the wound and makes the tissue protein denature and coagulate, so that the bleeding blood vessels are closed and the blood semen symptom is treated.

[0015] Further, the execution end is an end of the mirror tube away from the pipeline communication cavity along the central axis direction of the mirror tube, and the operation end is an end of the pipeline communication cavity away from the pipeline communication cavity along the central axis direction of the pipeline communication cavity; the pipeline communication cavity and the mirror tube which are in communication with each other have a main channel for placing a lens and an illuminating element, and the main channel penetrates through the execution end and the operation end. The pipeline communication cavity further has two communication valve twos, and the two communication valve twos are respectively used for connecting a perfusion device and a negative pressure suction device, so that the pipeline communication cavity is cleaned, or in other embodiments, the mirror tube is further provided with a channel corresponding to the communication valve two, which is used for flushing and absorbing blood, tissue debris or semen in front of the lens.

[0016] Further, the mirror tube is provided with a traction line, one end of the traction line is connected to the execution end, the pipeline communication cavity is further rotationally connected with a rotating shaft, and the other end of the traction line is connected with the rotating shaft; the number of the traction lines is at least two, and when the rotating shaft rotates around its own central axis, the execution end of the mirror tube exposed outside the guide sheath is driven to rotate in the same direction.

[0017] Further, the rotating shaft partially extends out of the pipeline communication cavity and is fixedly connected with a limiting rocker.

[0018] The beneficial effects of the present application are as follows:

[0019] 1. The mirror tube with electrodes is arranged in the field of view of the lens, the doctor can accurately locate the bleeding point through the real-time image obtained by the lens and implement electrocoagulation, and the abnormal blood vessels are burned out, so that the blood problem is fundamentally solved.

[0020] 2. The guide sheath of the application is provided with a deformed end portion with both the opening function and the anti-injury function, which can adapt to complex physiological structures. When the guide sheath needs to enter the ejaculatory duct, it is deformed into a shovel shape to open the ejaculatory duct; after the bevel completely enters the ejaculatory duct, the deformed end portion is switched to a cylindrical shape to protect the physiological tissue of the patient, effectively reducing the risk of complications such as perforation of the ejaculatory duct and bleeding.

[0043] The technical solutions in the embodiments of the present application are clearly and completely described below through specific specific embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the present specification. The present application can also be implemented or applied through other different specific embodiments. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0044] A seminal vesicle mirror, as shown in the drawings, comprises a seminal vesicle mirror body 1, the seminal vesicle mirror body 1 has an execution end 111 and an operation end 121, the execution end 111 is provided with a lens 112 and an illuminating element 113. The seminal vesicle mirror further comprises: Figures 1-19 An electrode 114 is partially arranged in the seminal vesicle mirror body 1 and extends out of the execution end 111, the electrode 114 is connected to a power supply through a lead wire 1141, and the energized electrode 114 coagulates and stops bleeding of abnormal blood vessels;

[0045] A guide sheath 2 is slidingly sleeved on the outer wall of the seminal vesicle mirror body 1, the guide sheath 2 has a connecting end 22 and a deformation end 21, the connecting end 22 limits the relative movement between the guide sheath 2 and the seminal vesicle mirror body 1 when the connecting end 22 is connected with the seminal vesicle mirror body 1, and the connecting mode of the connecting end 22 with the seminal vesicle mirror body 1 is specifically bolt connection. A cavity 213 is arranged between the inner wall and the outer wall of the guide sheath 2, the deformation end 21 is provided with an inclined surface 211, the cavity 213 is opened at the inclined surface 211, and an elastic membrane 212 is arranged between the deformation end 21 and the cavity 213. When the elastic membrane 212 is in a natural state, the deformation end 21 is shovel-shaped and used for picking up the ejaculatory duct orifice, and in the process of the elastic membrane 212 deforming outwardly from the inclined surface 211, the deformation end 21 is deformed from shovel-shaped to cylindrical.

[0046] In some embodiments of the present application, as shown in the drawings,

[0047] Figures 1-19 ​As shown, the outer wall of the connecting end 22 is provided with a gas pressure interface 221, and a connecting channel 225 is arranged between the outer wall and the inner wall of the guide sheath 2, the connecting channel 225 communicates the cavity 213 with the gas pressure interface 221, and when the gas flow moves to the cavity 213 through the gas pressure interface 221, the elastic membrane 212 is driven to deviate from the natural state. By arranging the gas pressure interface 221 connected to the cavity 213, the gas flow is pushed to the cavity 213 at the connecting end 22 of the guide sheath 2 left in the body, that is, the deformation state of the elastic flap can be changed, and the switching between the two forms of the deformed end 21 can be controlled. Specifically, in the process of the guide sheath 2 entering the seminal vesicle through the urethra of the patient and approaching the ejaculatory duct orifice, the cylindrical form of the deformed end 21 is maintained by pushing the gas flow to the cavity 213, so as to avoid causing physical damage to the surrounding tissues on the operation route during the movement of the guide sheath 2. When the doctor observes the ejaculatory duct orifice through the seminal vesiculoscope in the guide sheath 2 or determines the position of the ejaculatory duct orifice through other ways, the gas flow pushed into the cavity 213 is moved to the gas pressure interface 221, so as to control the elastic membrane 212 to return to the natural state, so that the cylindrical deformed end 21 is deformed into a spade shape, so as to pry the ejaculatory duct orifice.

[0048] In some embodiments of the present application, as Figures 1-19As shown, the perpendicular line of the inclined surface 211 and the central axis of the guide sheath 2 form an acute angle with the tip pointing to the connecting end 22; the number of the inclined surface 211 is two, and the two inclined surfaces 211 are equally spaced and arranged in a circular array around the central axis of the guide sheath 2, so that the deformed end 21 is shovel-shaped; the cavity 213 is arranged along the central axis of the guide sheath 2, and the cylinder piston 214 is sleeved in the cavity 213 and is in an initial position, and the elastic film 212 is in a natural state; during the movement of the cylinder piston 214 along the central axis of the guide sheath 2 to the deformed end 21, the elastic film 212 is radially expanded along the central axis of the guide sheath 2, so that the outer wall of the elastic film 212 is flush with the outer wall of the guide sheath 2. When the cylinder piston 214 moves to abut against the inner wall of the cavity 213, the inclined surface 211 is outwardly supported by the cylinder piston 214, so that the deformed end 21 is deformed from a shovel shape to a cylindrical shape. When the deformed end 21 is shovel-shaped and the execution end 111 of the seminal vesicle mirror does not extend through the deformed end 21, the two inclined surfaces 211 and the channel in the guide sheath 2 make the flat deformed end 21 have two symmetrical tapered ends 215. At the same time, the junction between the inclined surface 211 and the inner wall of the guide sheath 2 has an edge, and the junction between the inclined surface 211 and the outer wall of the guide sheath 2 has an edge, so that the tapered end can pick up the closed ejaculatory duct orifice. Among them, the single tapered end 215 or the flat shovel-shaped structure composed of two tapered ends 215 is easy to insert into the gap of the closed orifice, which is conducive to opening the closed ejaculatory duct orifice. However, when the flat deformed end 21 enters the ejaculatory duct, the edge on the tapered end 215 has the risk of damaging the inner wall of the ejaculatory duct, so when the inclined surface 211 enters the ejaculatory duct, the cylinder piston 214 that deviates from the initial position and expands the inclined surface 211 into an arc surface can eliminate the tapered end 215. So that the guide sheath 2 continues to move only the cylindrical side wall of the cylindrical end in contact with the inner wall of the ejaculatory duct, thereby effectively reducing the risk of damaging the inner wall of the ejaculatory duct.

[0049] In some embodiments of the present application, as Figures 1-19As shown, the sliding block piston 222 is arranged in the air pressure interface 221, and the elastic member 223 is arranged between the inner wall of the air pressure interface 221 and the sliding block piston 222. When the elastic member 223 is in a natural state, the elastic film 212 is also in a natural state. When the sliding block piston 222 moves towards the inner wall of the guide sheath 2, the elastic member 223 is compressed, and the airflow in the air pressure interface 221 moves towards the cavity 213, so that the elastic film 212 is deformed from the natural state. The sliding block piston 222 is arranged in the air pressure interface 221, and the cylinder piston 214 is arranged in the cavity 213, so that the space between the air pressure interface 221 and the cavity 213 is dynamically sealed. Therefore, the movement of the cylinder piston 214 in the cavity 213 can be controlled by moving the sliding block piston 222 in the air pressure interface 221, so as to indirectly realize the deformation control of the deformed end. The movement of the sliding block piston 222 is driven by an external force. When the external force is removed, the elastic member 223 is deformed to the natural state under the elastic force, and the sliding block piston 222 is pushed back to the initial position, so that the deformed end 21 returns to the shovel shape.

[0050] In some embodiments of the present application, as shown in Figures 1-19 The knob 224 is bolted to the air pressure interface 221, and the end of the knob 224 contacts the sliding block piston 222. When the knob 224 rotates around the central axis and moves towards the air pressure interface 221, the sliding block piston 222 is compressed, so that the deformed end 21 is deformed from the shovel shape to the cylindrical shape. The knob 224 has a rotation stroke, and the rotation stroke limits the rotation angle of the knob 224. The rotation stroke is limited by the height of the thread in the air pressure interface 221, and the maximum deformation of the elastic member 223 also limits the rotation stroke of the knob 224. During the twisting of the knob 224, the rotation stroke of the knob 224 can be confirmed by the perception of the damping change.

[0051] In some embodiments of the present application, as shown in Figures 1-19As shown, the seminal vesiculoscope body 1 comprises a pipeline communication cavity 12 and a mirror tube 11 in communication with each other; the pipeline communication cavity 12 is provided with a connecting head 126 at the end of the mirror tube 11, for inserting or screwing with the connecting end 22 of the guide sheath 2, and the deformed end 21 and the connecting end 22 of the guide sheath 2 further have a sheath tube 23, and the outer wall of the connecting end 22 is provided with a communication valve one 226; the sheath tube 23 is sleeved on the outside of the mirror tube 11, and the inner diameter of the sheath tube 23 is greater than the outer diameter of the mirror tube 11; when the communication valve one 226 is open and the guide sheath 2 enters the ejaculatory duct, the two sides of the communication valve one 226 form a fluid suction and perfusion passage. When the communication valve one 226 is closed, the suction and perfusion passages are sealed. The suction and perfusion operation is realized by connecting the communication valve one 226 and the suction and perfusion device, and the fluid injected in the perfusion operation is physiological saline or lubricant. The physiological saline is used to flush the blood and wounds in the ejaculatory duct in the electrocoagulation operation, and the lubricant is used to further reduce the risk of causing trauma to the ejaculatory duct in the process of expanding the guide sheath 2 in the ejaculatory duct. The fluid extracted in the suction operation includes blood, semen or tissue debris, so as to keep the vision in front of the seminal vesiculoscope clear and balance the cavity pressure in the ejaculatory duct. By arranging the communication valve one 226 capable of connecting the suction and perfusion device, when the seminal vesiculoscope performs the electrocoagulation hemostasis operation in the ejaculatory duct, it is beneficial to flush the bleeding point in time and absorb the smoke and debris generated by electrocoagulation.

[0052] In some embodiments of the present application, as shown in Figures 1-19 As shown, the inside of the seminal vesiculoscope body 1 is provided with an insulating channel 13, one end of the insulating channel 13 is opened at the execution end 111, the other end of the insulating channel 13 extends out of the outer wall of the pipeline communication cavity 12, and the insulating channel 13 is provided with a lead wire 1141 electrically connected with the electrode 114. When the electrode 114 contacts the wound and the lead wire 1141 is electrified, the electric current passes through the surrounding tissue of the wound and makes the tissue protein denature and coagulate, so as to realize the closure of the bleeding blood vessels and the treatment of hematospermia.

[0053] In some embodiments of the present application, as shown in Figures 1-19As shown, the execution end 111 is the end of the mirror tube 11 away from the pipeline communication cavity 12 along the central axis direction of the mirror tube 11, and the operation end 121 is the end of the pipeline communication cavity 12 away from the pipeline communication cavity 12 along the central axis direction of the pipeline communication cavity 12; the pipeline communication cavity 12 and the mirror tube 11 are in communication with each other and have a main passage 123 for placing the lens 112 and the illumination element 113, and the main passage 123 penetrates through the execution end 111 and the operation end 121. The illumination element 113 is specifically connected with a cold light source outside the seminal vesiculoscope through an illumination optical fiber, so as to guide the light generated by the cold light source through the optical fiber to provide safe illumination for the seminal vesicles; and the lens 112 is connected with an external image processing host through a data line or an optical fiber, so as to transmit the image captured by the lens 112 to the host and further display through a display, thereby improving the operation efficiency and safety by providing the image in the seminal vesicles for the physician. The pipeline communication cavity 12 also has two communication valves 122, which are respectively used for connecting the perfusion device and the negative pressure suction device, so as to facilitate cleaning of the pipeline communication cavity 12, or in other embodiments, the mirror tube 11 is also provided with a channel corresponding to the communication valve 122, which is used for flushing and absorbing blood, tissue debris or semen in front of the lens 112.

[0054] In some embodiments of the present application, as shown in Figures 1-19 The mirror tube 11 is provided with a traction line 115, one end of the traction line 115 is connected to the execution end 111, and the pipeline communication cavity 12 is also rotatably connected with a rotating shaft 124, and the other end of the traction line 115 is connected with the rotating shaft 124; the number of the traction line 115 is at least two, and when the rotating shaft 124 rotates around the central axis thereof, the execution end 111 of the mirror tube 11 exposed outside the guide sheath 2 is driven to rotate in the same direction.

[0055] In some embodiments of the present application, as shown in Figures 1-19 The rotating shaft 124 partially extends out of the pipeline communication cavity 12 and is fixedly connected with a limiting rocker 125, so that medical staff can drive the rotating shaft 124 by pushing and pulling the limiting rocker 125 when holding the seminal vesiculoscope body 1 to operate, thereby realizing direction control of the traction line 115 and the mirror tube 11 execution end 111 at the end of the traction line 115.
