Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a visual deep abdominal cavity suction and dissection system. Background Technology

[0002] In modern warfare and disaster relief, the treatment of abdominal battlefield injuries, such as liver and spleen rupture and retroperitoneal hematoma, requires extremely high timeliness. Current battlefield surgery faces severe challenges. Battlefield operating rooms often lack high-end cold light sources or deep retractors. When dealing with bleeding in the retrohepatic and deep pelvic cavities, doctors are often in a "blind" state, which can easily damage important blood vessels and nerves. Moreover, traditional suction devices are rigid straight rods that cannot bypass organs to reach hidden bleeding points. Furthermore, the need to frequently switch between suction devices, dissecting forceps, and retractors during surgery wastes precious rescue time. Existing instruments with light sources often pose a risk of heat burns. If the wire of a flexible instrument breaks, the tip cannot be reset, making it difficult to remove from the puncture sheath. In addition, high-intensity negative pressure can easily attract and tear fragile intestinal walls. Summary of the Invention

[0003] The purpose of this invention is to provide a visual deep abdominal cavity suction and dissection system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A handle is included, with a transmission rod connected to the front end of the handle, a bending assembly connected to the other end of the transmission rod, and a blunt suction head connected to the other end of the bending assembly. A shape memory alloy reset mandrel, two sets of traction steel wires, and multiple sets of optical fibers are disposed within the transmission rod and the bending assembly. Both ends of the two sets of traction steel wires are fixedly connected to the blunt suction head. A diffuser ring is connected to the surface of the blunt suction head, and one end of each optical fiber is connected to the diffuser ring. A rotating mechanism is provided inside the handle. Two sets of drive rods are provided, with a drive frame rotatably mounted at the middle of each drive rod. Two sets of extrusion grooved wheels are connected to the middle of each drive rod at a position between the inner sides of the drive frame. The other end of each drive rod passes through a handle and is connected to an adjustment component. An external connector is connected to the back of the handle. One end of a transmission rod passes through the handle and communicates with the external connector. A sealed magnetic control button is connected to the front end of the handle, and a trigger switch is connected to the inner side of the handle.

Each joint tube is connected to a limiting ball joint at its front end and a limiting ball groove is formed at its rear end corresponding to the limiting ball joint. An external covering layer is sleeved on the surface of the bending assembly.

[0006] Preferably, an internal frame is connected to the inner side of the transmission rod, and the internal frame and one side are provided with limit holes two corresponding to the shape memory alloy reset mandrel, and limit holes one corresponding to the traction steel wire.

[0007] Preferably, the blunt suction head has a pressure relief groove at its front end, and a heat dissipation channel is provided inside corresponding to the diffuser ring head.

[0008] Preferably, the power light source module includes a module housing located within an isolation chamber, a built-in battery pack is connected inside the module housing, a high-brightness LED spotlight is connected to the top of the module housing, the built-in battery pack and the high-brightness LED spotlight are electrically connected, and a Hall sensor is connected between the built-in battery pack and the high-brightness LED spotlight.

[0009] Preferably, the top of the isolation chamber is connected to a high-brightness LED focusing light and is provided with a high-temperature resistant optical glass window. A guide frame is connected to the top of the high-temperature resistant optical glass window. One end of the light guide fiber passes through the guide frame and abuts against the high-temperature resistant optical glass window. A protective coating is applied to the surface of the light guide fiber.

[0010] Preferably, the two sets of drive rods are vertically distributed, and a fixing frame is connected to the inner wall of the handle, with the drive frame connected to the fixing frame.

[0011] Preferably, a built-in fixing bracket is connected to the inner side of the handle, and an external fixing bracket is connected to the front end of the handle. The transmission rod is connected to the handle through the built-in fixing bracket and a Hall sensor.

[0012] Preferably, the adjustment assembly includes a control dial sleeved on one end of the drive rod, a movable friction damping plate connected to one side of the control dial, an indicator tooth connected to one side of the control dial, a buckle groove opened on the inner side of the control dial, a limit buckle connected to one end of the drive rod, a fitting groove opened at the end of the drive rod, and a traction spring connected in the fitting groove, a pressing plate connected to the other end of the traction spring, and a fixed friction damping plate connected to the handle surface corresponding to the movable friction damping plate.

[0013] In summary, the beneficial effects of this invention are: This application utilizes two sets of vertically distributed traction wires with differential traction to allow the bending component to bend at multiple angles in three-dimensional space, effectively bypassing organs to reach hidden bleeding points that are difficult to access with traditional straight instruments. A fiber optic cable, combined with a terminal astigmatism ring, introduces cold light into the deep abdominal cavity, providing unobstructed illumination and preventing damage to important blood vessels and nerves during blind operation. A pressure relief groove at the tip of the blunt suction head allows external air to be introduced when the suction head is blocked by tissue, preventing excessive negative pressure suction and effectively avoiding tearing of the fragile intestinal wall. The fiber optic cable works in conjunction with the heat dissipation channel within the suction head, using airflow to continuously remove heat and prevent tissue thermal damage caused by prolonged illumination. A shape memory alloy reset mandrel provides continuous and smooth reset force; even if the traction wire breaks, the mandrel can still straighten the bending component, ensuring smooth removal of the instrument from the puncture sheath. A friction damping plate in the adjustment component locks the bending angle, maintaining a stable surgical posture. Indicator teeth facilitate accurate reading and repeated operation. The handle uses a fully sealed magnetic control button structure with no exposed electrical interfaces, allowing for complete immersion sterilization and simplifying preoperative preparation.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-6 This invention provides a technical solution: a visual deep abdominal suction and dissection system, including a handle 1, which is a gun-grip structure for easy one-handed operation by the doctor. A transmission rod 2 is fixedly connected to the front end of the handle 1. The transmission rod 2 is a slender, hollow, rigid tube, and a bending assembly 3 is connected to its distal end. A blunt suction tip 4 is connected to the distal end of the bending assembly 3. The bending assembly 3 includes a connecting kit 31, which is fixedly connected to the distal end of the transmission rod 2. Multiple sets of articulated tubes 32 are sequentially connected to the distal end of each set of articulated tubes 32. Each end is fixedly connected to a limiting ball joint 37, and each end is provided with a limiting ball groove 36. The two adjacent sets of joint tubes 32 are connected by fitting the limiting ball joint 37 into the limiting ball groove 36 to achieve a ball joint connection, so that the adjacent joint tubes 32 can swing freely within a certain angle range. All joint tubes 32 are covered with an outer covering layer 301. The outer covering layer 301 is made of medical grade silicone or polyurethane elastomer material, which is elastic and has a smooth surface, and is used to wrap the internal structure and reduce tissue damage.

[0018] Each set of joint tubes 32 has an internal frame 33 fixedly connected to its inner side. The internal frame 33 has a cross structure and has a first limiting hole 34 and a second limiting hole 35. The first limiting hole 34 is used for the traction steel wire 7 to pass through, and the second limiting hole 35 is used for the shape memory alloy reset mandrel 6 to pass through and to radially limit the reset mandrel 6.

[0019] Two sets of traction steel wires 7 and a shape memory alloy reset mandrel 6, as well as multiple optical fibers 8, are axially threaded inside the transmission rod 2 and the bending assembly 3. The two sets of traction steel wires 7 are respectively arranged on the upper and lower sides and the left and right sides of the radial section of the bending assembly 3. One end of each set of traction steel wires 7 is fixedly connected to the proximal end of the blunt suction head 4, and the other end extends through the limiting hole 34 on the inner frame 33 of all joint tubes 32, then through the inside of the transmission rod 2, and finally extends into the inside of the handle 1, where it is clamped in the corresponding extrusion groove wheel 12. The shape memory alloy reset mandrel 6 is made of super-elastic nickel-titanium alloy. One end of it is fixed at the center position of the proximal end of the blunt suction head 4, and the other end extends axially through the limiting hole 35 on the inner frame 33 of each joint tube 32 and into the inside of the transmission rod 2, and finally is fixedly connected to the inside of the handle 1. The shape memory alloy reset mandrel 6 has super-elastic properties and can automatically return to its original straight state after bending, providing continuous reset force.

[0020] The handle 1 has two sets of drive rods 10 rotatably mounted inside. The axes of the two sets of drive rods 10 are perpendicular to each other. The middle section of each set of drive rods 10 is rotatably mounted on the drive frame 11. The drive frame 11 is fixedly connected to the fixed frame on the inner wall of the handle 1. The middle section of each set of drive rods 10 is fixedly connected to two sets of extrusion groove wheels 12 at the position between the inner sides of the drive frame 11. A clamping gap is formed between the two sets of extrusion groove wheels 12. A corresponding set of traction steel wires 7 is clamped in the clamping gap. When the drive rod 10 rotates, the extrusion groove wheels 12 rotate accordingly. Through friction, the traction steel wires 7 clamped in them move axially. The drive rod 10 controls the two sets of traction steel wires 7 respectively. By differentially pulling the two sets of traction steel wires 7, one end is pulled and the other end is released, so that the bending component 3 can be bent in any direction in the two-dimensional plane. Since the two sets of drive rods 10 are vertically distributed and combined with differential control, the bending component 3 can achieve multi-degree-of-freedom bending in three-dimensional space.

[0021] One end of the drive rod 10 passes through the housing of the handle 1 and is connected to an adjustment assembly 13 at its end. The adjustment assembly 13 includes a control dial 131, which is sleeved on the end of the drive rod 10. A groove 134 is provided on the inner side of the control dial 131. A limit buckle 135 is fixedly connected to the end surface of the drive rod 10. The limit buckle 135 is embedded in the groove 134, so that the control dial 131 and the drive rod 10 rotate synchronously in the circumferential direction and can slide relative to each other a certain distance in the axial direction. A fitting groove is provided at the end of the drive rod 10. One end of the traction spring 136 is fixed in the fitting groove, and the other end is fixedly connected to a pressing plate 137. The traction spring 136 always applies an inward pulling force to the control dial 131. A movable friction damping plate 132 is fixedly connected to the side of the control dial 131 near the housing of the handle 1. A fixed friction damping plate is fixedly connected to the surface of the housing of the handle 1 at the position corresponding to the movable friction damping plate 132. 103. When the doctor turns the control dial 131, it drives the drive rod 10 to rotate. The traction spring 136 pulls the compression plate 137 to generate a thrust on the control dial 131, which compresses the movable friction damping plate 132 and the fixed friction damping plate 103 to generate frictional resistance. The friction between the two locks the control dial 131 at the current angle, thereby maintaining the current bending posture of the bending component 3. Its frictional resistance is greater than the reset spring force of the memory alloy reset spindle 6, thus ensuring the stability after adjustment. The indicator tooth 133 is used to cooperate with the scale marking on the surface of the handle 1 (not shown in the figure) to facilitate the doctor to read the bending angle and achieve precise adjustment of the traction amount of the traction wire 7. When the doctor pulls the compression plate 137 outward, the resistance between the movable friction damping plate 132 and the fixed friction damping plate 103 decreases, and the spring force of the memory alloy reset spindle 6 can drive the bending component 3 to reset.

[0022] An isolation chamber 17 is connected to the inner side of the handle 1. The isolation chamber 17 forms a sealed independent cavity inside 1, which houses a power light source module. The power light source module includes a module housing 18, which is a closed shell and is installed inside the isolation chamber 17 by snap-fit. An internal battery pack 19 is connected inside the module housing 18. A high-brightness LED spotlight 20 is fixedly installed on the top of the module housing 18. The internal battery pack 19 is electrically connected to the high-brightness LED spotlight 20, and a Hall sensor 21 is connected in series between the internal battery pack 19 and the high-brightness LED spotlight 20. The Hall sensor 21 acts as an electronic switch to control the circuit on / off of the high-brightness LED spotlight 20.

[0023] At the top of the isolation chamber 17, corresponding to the position of the high-brightness LED spotlight 20, a high-temperature resistant optical glass window 171 is connected and installed. The high-temperature resistant optical glass window 171 is made of high-temperature resistant quartz glass or sapphire glass, which has good light transmission and heat resistance. A guide frame 172 is connected to the top of the high-temperature resistant optical glass window 171. One end of the light guide fiber 8 passes through the guide frame 172 and abuts against the surface of the high-temperature resistant optical glass window 171, while the other end extends along the transmission rod 2 and the inside of the bending assembly 3, and finally connects to the light-diffusing ring head 9 on the surface of the blunt suction head 4. The surface of the light guide fiber 8 is coated with a protective coating to improve the bending resistance and corrosion resistance of the fiber, while reducing light attenuation during transmission. As can be seen from the attached figure, the light guide fiber 8 located in the bending assembly 3 is arranged in a spiral shape.

[0024] The sealed magnetic control button 15 is located at the front end of the handle 1. It employs a fully sealed magnetic control button structure, consisting of an elastic silicone cap and a built-in permanent magnet. The elastic silicone cap is a fully enclosed structure, forming a continuous sealed wall with the handle 1 housing, ensuring complete isolation between the handle 1's interior and the outside world. This facilitates cleaning and disinfection and eliminates any exposed electrical interfaces. The built-in permanent magnet is fixed to the lower inner side of the elastic silicone cap. When a doctor presses the sealed magnetic control button 15 through sterile gloves, the elastic silicone cap undergoes elastic deformation, causing the built-in permanent magnet to shift and resulting in a change in the surrounding magnetic field. This magnetic field energy penetrates the outer shell of the isolation chamber 17 and the module outer shell 18, non-contactly triggering the Hall sensor 21 located inside the module outer shell 18. The Hall sensor 21 detects… Upon detecting a change in the magnetic field, the internal electronic switch closes, connecting the circuit between the built-in battery pack 19 and the high-brightness LED spotlight 20. The high-brightness LED spotlight 20 illuminates, and the light emitted by it is coupled through the high-temperature resistant optical glass window 171 into the light guide fiber 8. The light guide fiber 8 then conducts the light to the diffuser ring 9 on the surface of the blunt suction head 4. The diffuser ring 9 evenly scatters the light into the surgical field of view, achieving deep abdominal cavity illumination. When the doctor releases the sealed magnetic control button 15, the elastic silicone cap returns to its initial state under its own elastic force, causing the built-in permanent magnet to reset to its initial position. The magnetic field around the Hall sensor 21 returns to its initial state, its internal electronic switch disconnects, the circuit of the high-brightness LED spotlight 20 is disconnected, and the light goes out.

[0025] The front end of the blunt suction tip 4 has a blunt round head structure to avoid sharp damage to the tissue. The front end of the blunt suction tip 4 has a pressure relief groove 41, which is used to introduce external air through the pressure relief groove 41 when the suction tip is completely blocked by tissue during the suction process, so as to avoid the formation of excessive negative pressure suction force that damages fragile tissue.

[0026] One end of the transmission rod 2 passes through the inside of the handle 1 and communicates with the external connector 14. The external connector 14 is located on the back side of the handle 1 and is used to connect to the external negative pressure suction pipeline. The negative pressure is transmitted to the front end of the blunt suction head 4 through the external connector 14, the inner cavity of the transmission rod 2, and the inner cavity of the bending component 3 to realize the suction function.

[0027] The trigger switch 16 is located on one side of the handle 1 and adjacent to the sealed magnetic control button 15. The trigger switch 16 can be a mechanical valve structure, used to control the opening and closing of the suction airway. When the doctor pulls the trigger switch 16, the suction airway opens and suction begins. When the doctor releases the trigger switch 16, the suction airway closes and suction stops.

[0028] The blunt suction tip 4 has a heat dissipation channel 42 inside corresponding to the diffuser ring head 9. The heat dissipation channel 42 is connected to the suction passage. During the suction process, external gas or liquid enters the blunt suction tip 4 through the pressure relief groove 41. When it flows over the surface of the diffuser ring head 9, it carries away the heat and is discharged through the suction passage, realizing continuous passive heat dissipation of the diffuser ring head 9 and effectively preventing the diffuser ring head 9 from overheating and burning the tissue due to prolonged illumination.

[0029] The optical window of the diffuser ring 9 is frosted or has a microprism structure, which makes the emitted light evenly scattered to the surrounding tissue, avoiding the formation of local bright spots that may cause glare interference to the operator, while expanding the illumination coverage. A gap of 0.5~1mm is maintained between the high-temperature resistant optical glass window 171 and the high-brightness LED spotlight 20 to prevent the heat of the high-brightness LED spotlight 20 from being directly conducted to the glass window and causing local overheating.

[0030] Working principle: In use, the external connector 14 is first connected to the external negative pressure suction line to ensure unobstructed negative pressure passage. The doctor holds the handle 1 with a gun grip and inserts the transmission rod 2 along with the bending component 3 into the patient's abdominal cavity through the puncture sheath or surgical incision. It is gradually advanced along the surface of the organ to the target deep area. During the advancement, the doctor can turn the control dial 131 in the adjustment component 13 according to the actual needs of the surgical field. This drives the squeezing groove wheel 12 to rotate through the drive rod 10. The squeezing groove wheel 12 drives the two sets of traction steel wires 7 to generate phase through friction. Regarding displacement, the pulling force of the traction wire 7 is transmitted to the blunt suction head 4 through the joint tube 32, causing the bending component 3 to undergo corresponding bending deformation in three-dimensional space. This allows it to flexibly bypass organs such as the liver and intestines, precisely delivering the blunt suction head 4 to hidden bleeding points or tissue interfaces requiring dissection. Once the bending angle reaches the ideal state, the control dial 131 is released, and the traction spring 136 presses the movable friction damping plate 132 against the fixed friction damping plate 103 through the compression plate 137. The friction between the two locks the drive rod 10 and the bending component 3. In the current position, the doctor then presses the sealed magnetic control button 15, which triggers the high-brightness LED spotlight 20 non-contactly via the Hall sensor 21. The light is conducted through the light guide fiber 8 to the astigmatism ring head 9, evenly illuminating the surgical field. At the same time, the heat generated by the astigmatism ring head 9 is continuously carried away as the negative pressure suction airflow flows through the heat dissipation channel 42, preventing tissue burns. The doctor pulls the trigger switch 16 to open the suction air path. The negative pressure is transmitted through the external connector 14, the transmission rod 2, and the inner cavity of the bending component 3 to the front end of the blunt suction head 4, for suctioning fluid, blood, or adsorption of the surgical area. In the assisted dissection operation, when the tip of the blunt suction tip 4 is completely blocked by tissue, the pressure relief groove 41 automatically introduces external air to reduce the suction force and prevent damage to fragile tissue. If the angle needs to be adjusted during the operation, the doctor can pull the compression plate 137 outward to release the frictional resistance, so that the shape memory alloy reset mandrel 6 and the auxiliary bending component 3 can be reset or the angle readjusted. After the operation is completed, release all the control components, and the shape memory alloy reset mandrel 6 drives the bending component 3 to automatically return to the straight rod state, ensuring that the instrument can be smoothly pulled out of the puncture sheath. The entire operation is completed by removing the instrument.
