Description

Technical Field

[0001] This invention relates to the field of surgical medical devices, specifically a dual-lens combined harvesting device for transvesical prostatectomy. Background Technology

[0002] Endoscopic enucleation of the prostate (TURP) is the mainstream surgical method for treating benign prostatic hyperplasia (BPH). Currently, TURP primarily uses laser and plasma energy sources for cutting. However, high-power lasers and tissue shredders are expensive, limiting their widespread adoption in primary hospitals. Regardless of the energy source used, the surgical steps are as follows: 1. First, the enlarged prostate gland is completely (or mostly) enucleated from the capsule, and then the free glandular tissue is pushed back into the bladder cavity or suspended near the bladder neck; 2. Special instruments are used to shred and recover the free prostate tissue, or plasma is used to cut large pieces of prostate tissue piece by piece, and then the strips of tissue are flushed out of the bladder. However, this step-by-step operation results in the enucleated free tissue occupying surgical space, affecting the surgical field of vision, and making it difficult for the surgeon to locate the cutting surface, easily leading to bleeding. Simultaneously, the bladder is also susceptible to iatrogenic injury.

[0003] In addition, the existing prostate enucleation tools only have one endoscope lens at the cutting end. Therefore, in order to ensure the safety of the operation, the single lens on the existing enucleation tools can only perform a part-time task, which also hinders the simultaneous operation of enucleation and shredding and recycling.

[0004] Furthermore, for some patients with enlarged prostates, urethral strictures, or other special conditions, urethral enucleation surgery cannot be performed using the aforementioned urethral endoscopic approach. Due to the prostate's unique anterior location, current straight-rod endoscopes cannot be used to perform the surgery via the abdomen near the pubic bone and through the bladder. Therefore, these patients still require traditional open surgery. However, this treatment method causes significant trauma to the patient and is detrimental to postoperative recovery.

[0005] Therefore, in view of the above shortcomings, a surgical dual-lens combined harvesting device for transvesical prostate enucleation is designed. Summary of the Invention

[0006] The technical problem this invention aims to solve is that when performing prostate enucleation using existing tools, the enucleation and pulverization processes need to be performed in separate steps, resulting in low surgical safety and efficiency. It also addresses the disadvantages of traditional open surgery for special patients with conditions such as large prostate volume or urethral stricture that preclude endoscopic enucleation.

[0007] The technical solution adopted by this invention to solve its technical problem is:

[0008] A dual-lens combined harvesting device is provided for transvesical prostate enucleation, comprising:

[0009] The working part is an arc-shaped bent rod structure, wherein the bending angle is 65° to 80°, and a first channel, a second channel, a third channel, a fourth channel and a fifth channel are respectively opened from the front end to the rear end of the working part;

[0010] An eyepiece adapter is installed at the rear end of the working part;

[0011] A handle is attached to the rear end of the eyepiece adapter; a working handle that can be pressed and rotated is hinged to the outside of the handle.

[0012] A pulverizer is inserted into the fifth channel, wherein the feed inlet of the pulverizer is exposed at the front end of the fifth channel; the discharge outlet of the pulverizer is connected to a first valve installed on the rear side wall of the working piece; a hinge bar is provided in the feed inlet, and a flexible shaft is installed at its rear end. The rear end of the flexible shaft is connected to a motor installed at the rear end of the pulverizer, wherein the hinge bar is provided with blade-shaped hinge teeth.

[0013] A metal wire is inserted and withdrawn into the first channel, with its front end exposed at the front end of the first channel, so that it is positioned on one side of the crusher. The rear end of the metal wire is connected to the rotating end of the working handle located inside the handle. The insertion and withdrawal action of the metal wire is controlled by the working handle to perform electrocutting or electrocoagulation.

[0014] A first camera is installed at the front end of the second channel and illuminates the metal wire. The rear end of the first camera extends to the eyepiece adapter end.

[0015] A second camera is installed at the front end of the fourth channel and illuminates the feed inlet. The rear end of the second camera extends to the eyepiece adapter end.

[0016] The front end of the fourth channel extends through the front end of the working piece, and the rear end of the fourth channel is connected to the second valve.

[0017] Preferably, the combine harvester also includes a stripping component disposed at the front end of the working component, which is a cylindrical shell structure and has a cutting groove on one side. The front end of the crusher is placed in the cutting groove, and the feed inlet is disposed on the same side as the opening of the cutting groove.

[0018] A wire channel is provided along the edge of the gouging groove. The tip of the wire enters from one end of the wire channel and extends from the other end, forming a "U" bend. The tip of the wire then enters a return channel located on the opposite side of the first channel, allowing the wire to extend toward the rear end of the workpiece.

[0019] Preferably, the rear end of the reversal channel is connected to the first channel, and the front end of the metal wire is folded back to the first channel through the reversal channel and extends to the rear end of the first channel, wherein the diameter of the reversal channel is 3-5 times the diameter of the metal wire.

[0020] Preferably, the front end of the stripper has an arc-shaped structure.

[0021] Preferably, the peeling element is a transparent structure.

[0022] Preferably, a bearing is provided on the inner side of the front end of the pulverizer, and the front end of the hinge bar is rotatably mounted on the inner side of the pulverizer via the bearing.

[0023] Preferably, the motor is equipped with a mounting bracket, and the motor is fixed to the inner wall of the workpiece by the mounting bracket.

[0024] Preferably, a sixth channel is provided from the front end to the rear end of the workpiece, and a light beam is provided in the sixth channel, wherein the front end of the light beam extends to the front end of the sixth channel, and the rear end of the light beam extends to the beam guide interface on the rear side wall of the workpiece.

[0025] Preferably, the first valve and the second valve are positioned on opposite sides of the working handle.

[0026] Preferably, the working handle is provided with a first button for controlling the electric cutting of the metal wire and a second button for controlling the electrocoagulation of the metal wire, and a third button for controlling the start and stop of the pulverizer is provided on the handle side.

[0027] The beneficial effects of this invention are: by bending the working piece in an arc shape of 65°–80°, it can enter the bladder and then the prostate through an opening in the abdominal wall above the pubic bone. Since the prostate is located below the bladder neck, the curved structure ensures the safety of the working piece's path and facilitates operation at the rear end. This enables prostate enucleation surgery performed from above the pubic bone through the abdominal wall and via the bladder. It overcomes the disadvantages of traditional open surgery for patients with large prostates, urethral strictures, or other special conditions that prevent endoscopic enucleation via urethral insertion.

[0028] Furthermore, a cutting wire channel and a shredder channel are respectively established on the working piece, with the shredder channel located on one side of the cutting wire channel. Lenses are installed at the front end of the working piece to irradiate the working ends of the cutting wire and the shredder, respectively. These lenses can monitor the working status of both in real time, enabling simultaneous removal and shredding while ensuring surgical safety. This avoids free tissue from occupying surgical space and obstructing the surgical view, thus improving surgical safety and efficiency. In addition, this device is less expensive than existing laser and plasma surgical equipment, suitable for mass production, and can be designed for single use, making it more hygienic and convenient, and suitable for widespread use in primary hospitals.

[0041] 7-beam, 8-sheath. Detailed Implementation

[0042] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and not for limiting the scope of the invention. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0043] In one specific embodiment, a dual-lens combined harvesting device is provided for transvesical enucleation of the prostate, primarily used in this surgical procedure. Specifically, it includes a working component 1, equivalent to the endoscope rod in a traditional endoscope, but this component 1 is an arc-shaped, bent rod structure with a bending angle of 65°–80°. The main purpose of setting this bending angle is to ensure the patient lies supine during surgery, with an opening made above the pubic bone in the abdominal wall and the combined harvesting device inserted through this opening. Since the surgical component 1 needs to enter the prostate via the bladder, and the prostate is located below the bladder neck, this ensures a safe path for the component 1 and facilitates operation at its rear end. This allows for prostate enucleation via the abdominal wall and bladder, representing a significant difference from traditional transurethral surgery and conventional open surgery. The specific bending angle can be selected as 65°, 70°, 75°, or 80°.

[0044] To ensure simultaneous and safe resection and retrieval during surgery, five channels—a first channel 1.1, a second channel 1.2, a third channel 1.3, a fourth channel 1.4, and a fifth channel 1.5—are provided from the front to the rear of the working piece 1. These channels are typically built into a mandrel within the working piece 1, which is made of a readily processable and moldable plastic material. This type of channel is common in existing endoscopes and will not be elaborated upon further here. Additionally, an eyepiece adapter 4 is installed at the rear of the working piece 1 to transmit image information acquired by the lens to a display terminal. Furthermore, a handle 5 is installed at the rear of the working piece 1 for ease of use by the surgeon. The handle 5 can be integrated with the rear of the eyepiece adapter 4 to form a single, compact structure.

[0045] Based on this, to facilitate the recovery of the removed tissue and avoid it occupying surgical space and affecting the surgical field of vision, a pulverizer 6 is inserted into the fifth channel 1.5. Its specific structure is as follows: a feed inlet 6.4 is located at the front end of the pulverizer 6, and a discharge outlet 6.5 is located at the rear end. The transport channel of the pulverizer 6 is a tube, with the feed inlet 6.4 located at one end and the discharge outlet 6.5 located at the other end—a common structure. However, to allow it to be inserted into the fifth channel 1.5, the shape of the tube should be compatible with the shape of the working piece 1, i.e., it should be a bent shape or capable of being bent. After installation, the feed inlet 6.4 protrudes from the front end of the fifth channel 1.5; the discharge outlet 6.5 at the rear end is connected to the first valve 1a installed on the rear side wall of the working part 1. Specifically, the first valve 1a is usually screwed and sealed onto the side wall of the working part 1, so it can connect to the discharge outlet 6.5 after screwing. This can be understood as the first valve 1a being plugged into or screwed onto the discharge outlet 6.5. This is also a common connection method. In use, the first valve 1a is connected to an external negative pressure suction device to generate suction, thus achieving the function of negative pressure suction.

[0046] To pulverize the removed prostate tissue and prevent clogging of the pulverizer 6's transport pipes, a hinge rod 6.1 with blade-shaped teeth is installed inside the feed inlet 6.4. A flexible shaft 6.2 is installed at the rear end of the hinge rod 6.1 to allow it to rotate, and the rear end of the flexible shaft 6.2 is connected to a motor 6.3 installed at the rear end of the pulverizer 6; the flexible shaft 6.2 is a flexible steel wire shaft. To ensure smooth agitation of the hinge rod 6.1 within the feed inlet 6.4, two installation methods are available: First, since the agitation force is not very large, the hinge rod 6.1 can float and press against the feed inlet 6.4 via the flexible shaft 6.2, i.e., the front end of the hinge rod 6.1 presses against the inner front end of the pulverizer 6; second, a bearing is installed inside the front end of the pulverizer 6, and the front end of the hinge rod 6.1 is rotatably mounted inside the pulverizer 6 via the bearing, allowing the hinge rod 6.1 to rotate smoothly and improving pulverization efficiency. In addition, to better facilitate the installation and fixation of the pulverizer 6, a mounting bracket 6.6 is installed on the motor 6.3. During installation, the pulverizer 6 is gradually inserted into the fifth channel 1.5. When the front end of the pulverizer 6 reaches the designated position, the mounting bracket 6.6 will abut against the rear end of the working part 1, and the mounting bracket 6.6 can support the inner side of the working part 1, thereby fixing the motor 6.3 to the inner wall of the working part 1, and also achieving overall fixation of the pulverizer 6.

[0047] To achieve the excision of the internal tissue of the gland, a metal wire 3 is also included, which is inserted and withdrawn into the first channel 1.1, with its front end exposed at the front end of the first channel 1.1 and placed on one side of the pulverizer 6. When energized, it is used for electro-cutting and electrocoagulation hemostasis. The metal wire 3 can be a tungsten alloy electro-cutting wire or a stainless steel electro-cutting wire. It is preferred to use a tungsten alloy electro-cutting wire to prevent adhesion, cut more effectively, and cause less damage to deeper layers.

[0048] To enable control of the extension and retraction of the metal wire 3, facilitating the surgeon's cutting and hemostasis at different locations on the gland, a working handle 5a is hinged to the handle 5, with one end of the working handle 5a positioned inside the handle 5. The rear end of the metal wire 3 is connected to this end, allowing the insertion and withdrawal of the metal wire 3 to be controlled by the hand. To enable the metal wire 3 to retract automatically, a torsion spring is installed on the hinge shaft of the working handle 5a, allowing the working handle 5a to automatically return to its original position after being pressed.

[0049] Based on the above, to ensure the simultaneous and safe removal and shredding / recycling, it is necessary to monitor the cutting of the metal wire 3 and the recycling by the shredder 6 separately. Therefore, two independently operating cameras are used:

[0050] The first camera is installed at the front end of the second channel 1.2, illuminating the metal wire 3. The second camera is installed at the front end of the fourth channel 1.4, illuminating the feed inlet 6.4. The cameras are typically positioned close to either the metal wire 3 or the feed inlet 6.4. The rear ends of both cameras extend to the eyepiece adapter 4 and connect to a display terminal, allowing for simultaneous display on the same screen. Therefore, the surgeon can simultaneously view the current operating status of the metal wire 3 and the feed inlet 6.4 during surgery, further enhancing surgical safety.

[0051] In addition, in order to clean and cool the surgical site during surgical cutting, a fourth channel 1.4 is provided inside the working piece. Its front end extends through the front end of the working piece 1, and its rear end is connected to the second valve 1b. The connection method between the two is the same as the connection method between the outlet 6.5 and the first valve 1a, which will not be described in detail here.

[0052] In addition, since the working component 1 has a bent structure, an outer sheath 8 is included to facilitate its insertion into the body through the abdominal incision. This sheath is a flexible tube that is inserted into the abdominal incision to establish an implantation channel. After the working component 1 is inserted into the outer sheath 8, the outer sheath 8 can bend along with the working component 1, achieving a fitted insertion that facilitates the insertion, withdrawal, and swinging operation of the working component 1. Furthermore, a sealing sleeve is provided on the inner wall of the outer sheath 8, through which the working component 1 is sealed to the outer sheath 8, thus maintaining pneumoperitoneum pressure.

[0053] Based on the above technical solutions, the following improvements are made to the gland enucleation procedure to better remove the glandular tissue. Specific improvements are as follows:

[0054] The combine harvester also includes a stripping component 2 located at the front end of the working piece 1. This component has a cylindrical shell structure and a cutting groove 2.2 on one side, which, when opened, forms a spoon shape to gather the cut glands. Furthermore, to achieve efficient cutting by the stripping component 2, a metal wire 3 needs to be positioned along the edge of the cutting groove 2.2. Specifically, a metal wire channel 2.1 is provided along the edge of the cutting groove 2.2. The front end of the metal wire 3 enters from one end of the metal wire channel 2.1 and extends from the other end, forming a "U" bend. The front end of the metal wire 3 is then inserted into a return channel 1.11 located on the opposite side of the first channel 1.1, extending the metal wire 3 towards the rear end of the working piece 1. Therefore, it can be seen that the "U"-shaped bent metal wire 3 set along the contour of the cutting groove 2.2 can increase the range of the "cutting blade", and the "U" bend is more conducive to the realization of the removal action, thereby effectively improving the removal efficiency. It can also be seen that the removed tissue is directly collected through the cutting groove 2.2, and the feed port 6.4 is set on the same side as the groove opening of the cutting groove 2.2, so that the removed tissue can quickly enter the feed port 6.4 for crushing and harvesting.

[0055] In addition, when in use, the metal wire 3 has a certain supporting strength and toughness. By controlling the working handle 5a, the metal wire 3 can push the entire peeling part 2 to move back and forth to increase the cutting range. The entire peeling part 2 can be pushed forward by the metal wire 3 by 2cm, which further improves the ease of use.

[0056] Based on the above arrangement of the folded-back metal wire 3, to prevent the folded-back metal wire 3 from completely penetrating the working piece 1, the rear end of the folding-back channel 1.11 can be connected to the first channel 1.1, i.e., connected at the front end of the working piece 1. During installation, the front end of the metal wire 3 is folded back to the first channel 1.1 through the folding-back channel 1.11 and extends to the rear end of the first channel 1.1. In this way, there are two folded-back metal wires 3 within the first channel 1.1, which further improves the strength and toughness of the metal wire and enhances the controllability of the peeling piece 2. Furthermore, to allow the metal wire 3 to still extend and retract, the diameter of the folding-back channel 1.11 is set to 3-5 times the diameter of the metal wire 3, allowing the folded-back metal wire to slide within the folding-back channel 1.11.

[0057] During surgery, to avoid the peeling piece 2 from injuring other tissues of the gland and to reduce the occurrence of accidents, the front end of the peeling piece 2 is set as an arc-shaped structure.

[0058] In addition, to improve the surgical field of vision and surgical safety, the dissecting element 2 is designed with a transparent structure. This transparent structure can be made of polypropylene, which has high strength and high temperature resistance. The metal wire 3 is usually isolated from the dissecting element 2 by an insulating material, better protecting the dissecting element and enabling both electrocautery and electrocoagulation functions.

[0059] Similarly, to further improve the clarity of the surgical field, a sixth channel 1.6 is provided from the front end to the rear end of the working piece 1. A beam 7 is provided in the sixth channel 1.6. The front end of the beam 7 extends to the front end of the sixth channel 1.6, and the rear end of the beam 7 extends to the beam guide interface 1c on the rear side wall of the working piece 1 and is connected to the light source generating device. Thus, the beam 7 can improve the brightness of the surgical space and improve the safety of the operation.

[0060] During the surgical procedure, in order to facilitate the opening and closing of the first valve 1a and the second valve 1b, the first valve 1a and the second valve 1b are respectively placed on both sides of the working handle 5a.

[0061] Similarly, to facilitate the control of the power supply to and from the metal wire 3 and the shredder 6, the working handle 5a is equipped with a first button 5a1 for controlling the electrocuting of the metal wire 3 and a second button 5a2 for controlling the electrocoagulation of the metal wire 3. Furthermore, a third button 5b is provided on the handle 5 for controlling the start and stop of the shredder 6. This allows for quick and easy operation by the operator.

[0062] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
