Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an easy-to-use suction device. Background Technology

[0002] With the development of medicine, more and more diseases that require surgical treatment tend to use minimally invasive treatment. Minimally invasive surgery has a small incision, which facilitates later recovery and leaves a small surgical scar, making it more acceptable to patients. However, the operating field of minimally invasive surgery is narrow, and various instruments are needed to assist doctors in observation and operation. The negative pressure suction device is a medical device commonly used in surgery to remove blood, fluid and other contaminants generated in the surgical area to avoid obstructing the surgical area and affecting the doctor's operation. It is an indispensable auxiliary tool in minimally invasive surgery.

[0003] During minimally invasive surgery, not only is a suction device used to remove contaminants from the surgical area, but an irrigator is also used to rinse the surgical area. The contaminants generated after rinsing are then removed by the suction device. Therefore, doctors need to frequently change the suction device and irrigator during the operation, which makes the operation complicated, reduces surgical efficiency, and increases surgical risks. At the same time, the noise generated by the continuous operation of the negative pressure machine during the operation can lead to a poor surgical environment, affect the concentration of medical staff, and further increase surgical risks. Therefore, this application provides an easy-to-use suction device to meet the needs. Utility Model Content

[0004] The technical problem to be solved by this invention is to provide an easy-to-use suction device to solve the problem that doctors need to frequently change suction devices and irrigation devices during existing surgical procedures, which makes the surgical operation complicated.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An easy-to-use suction device includes a handle and a sleeve mounted on the handle. The handle can be connected to a negative pressure machine and a flushing machine via two sets of hoses. The sleeve contains a suction tube and a flushing tube. The handle contains a conversion element. The ends of the suction tube and the flushing tube are connected to the conversion element to switch between flushing and suction functions.

[0007] Optionally, the sleeve is a cylindrical structure closed at one end, with a flushing port on the side wall of the closed end of the sleeve, and multiple suction ports are also provided at this end, with the area of ​​the flushing port being larger than the area of ​​the suction ports.

[0008] Optionally, the inner wall of the sleeve is fixedly connected with multiple sets of fixing rings, which are arranged in a straight line and located on the same axis as the flushing port.

[0009] Optionally, the flushing pipe is an L-shaped pipe with an inclined head, the flushing pipe passes through multiple sets of fixing rings and is slidably connected to them, and the flushing pipe is made of PVC material.

[0010] Optionally, a baffle is fixedly connected to the inner wall of the sleeve, and the baffle is an inclined plate structure located on one side of the flushing port.

[0011] Optionally, the grip is shaped like a gun handle, with an adjustment box fixedly connected to the muzzle. A flushing pipe connection hole is provided inside the grip, with one end connected to the interior of the adjustment box and the other end penetrating the side wall of the grip, where a flushing pipe interface is located. Below the flushing pipe connection hole, a negative pressure pipe connection hole is provided, with one end connected to the interior of the adjustment box and the other end penetrating the side wall of the grip, where a negative pressure pipe interface is located.

[0012] Optionally, the adjusting box body is a cylindrical structure closed at both ends, the side wall of the adjusting box body has a connection port, and the bottom of the adjusting box body has a connecting hole.

[0013] Optionally, the conversion component is a cylindrical structure with a diameter smaller than the inner diameter of the adjustment box. The conversion component has two sets of protrusions symmetrically arranged on its side wall. The protrusions are arc-shaped and smoothly connected to the surface of the conversion component. A turntable is fixedly connected to the bottom of the conversion component, and a corner block is fixedly connected to the bottom of the turntable.

[0014] Optionally, a flushing through hole is provided on the outward protrusion of the protrusion, the flushing through hole passes through two sets of the protrusions, a T-shaped sliding groove is provided on the side wall of the conversion member, the sliding groove surrounds the conversion member and passes through the middle of the protrusion, a suction through hole is provided at the lower part of the protrusion, the suction through hole passes through the conversion member, and the channel formed by the flushing through hole and the channel formed by the suction through hole are perpendicular to each other.

[0015] Optionally, the distance between the tops of the two sets of protrusions is the same as the inner diameter of the adjustment box, and the height of the conversion element is the same as the inner height of the adjustment box.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, by setting up a conversion device, in conjunction with the suction tube and irrigation tube installed inside the cannula, the effect of switching back and forth between irrigation and suction states can be achieved. At the same time, the suction tube and irrigation tube are integrated into one unit, which can avoid changing surgical instruments back and forth when switching between the two functions, thereby simplifying the surgical operation steps, improving the surgical effect, and reducing the surgical risk. When the conversion device is adjusted to a suitable position, the suction tube and irrigation tube can be closed at the same time, thereby reducing the vibration transmitted to the suction tube and irrigation tube by the negative pressure machine and the irrigation machine, reducing the noise generated by the vibration, effectively optimizing the surgical environment, and further reducing the surgical risk.

[0018] By setting a protrusion, the flushing pipe can be moved when the state of the flushing pipe is adjusted by rotating the conversion component, thereby extending the head of the flushing pipe to the outside of the sleeve for easy flushing. A sliding groove is opened on the protrusion, which is matched with the end of the flushing pipe that fits the sliding groove, so that the flushing pipe always fits tightly with the conversion component as it rotates. When the top of the protrusion is misaligned with the end of the flushing pipe, the flushing pipe can be pulled back, thereby retracting the head of the flushing pipe into the sleeve and blocking the head end of the flushing pipe to prevent the flushing pipe port from being blocked by dirt.

[0033] like Figures 1 to 5 As shown, an embodiment of this utility model provides a user-friendly suction device, including a handle 2 and a sleeve 1 mounted on the handle 2. The handle 2 can be connected to a negative pressure machine and a flushing machine via two sets of flexible hoses. The sleeve 1 contains a suction tube 3 and a flushing tube 4. The handle 2 also contains a conversion element 5. The ends of the suction tube 3 and the flushing tube 4 are connected to the conversion element 5 to switch between flushing and suction functions. By setting the conversion element 5, in conjunction with the suction tube 3 and the flushing tube 4 inside the sleeve 1, the device can switch between flushing and suction states. Furthermore, the integrated suction tube 3 and flushing tube 4 avoid the need to change surgical instruments repeatedly when switching between the two functions, thus simplifying surgical procedures, improving surgical outcomes, and reducing surgical risks. Adjusting the conversion element 5 to a suitable position can also simultaneously close the suction tube 3 and the flushing tube 4, thereby reducing the vibration transmitted from the negative pressure machine and the flushing machine to the suction tube 3 and the flushing tube 4, reducing noise generated by vibration, effectively optimizing the surgical environment, and further reducing surgical risks.

[0034] like Figures 1 to 3 As shown, the sleeve 1 is a cylindrical structure closed at one end. A rinsing port 6 is provided on the side wall of the closed end of the sleeve 1. Multiple suction ports 7 are also provided at this end. The area of ​​the rinsing port 6 is larger than the area of ​​the suction ports 7. The rinsing port 6 is used to clean the surgical site in conjunction with the rinsing tube 4. The suction ports 7 are used to filter large pieces of debris in the suctioned waste to prevent the suction tube 3 from being blocked. Multiple sets of fixing rings 9 are fixedly connected to the inner wall of the sleeve 1. The multiple sets of fixing rings 9 are arranged in a straight line and are located on the same axis as the rinsing port 6. A baffle 8 is fixedly connected to the inner side wall of the sleeve 1. The baffle 8 is an inclined plate structure and is located on one side of the rinsing port 6. The baffle 8 is inclined downward towards the side closer to the rinsing tube 4 to guide the deformation direction of the rinsing tube 4 so that it can accurately extend out of the rinsing port 6.

[0035] like Figure 2 and Figure 4As shown, the flushing pipe 4 is an L-shaped pipe with an inclined tip, passing through and slidably connected to multiple sets of fixing rings 9. The flushing pipe 4 is made of PVC material, which has a certain supporting force, but can still deform under certain stress. The deformable nature of the flushing pipe 4 allows the tip of the flushing pipe 4 to extend from the flushing port 6 to the outside of the sleeve 1, thus facilitating the flushing function. The handle 2 is shaped like a gun handle. An adjustment box 10 is fixedly connected to the muzzle of the handle 2. A flushing pipe connection hole 14 is provided inside the handle 2. One end of the flushing pipe connection hole 14 is connected to the inside of the adjustment box 10, and the other end of the flushing pipe connection hole 14 penetrates the side wall of the handle 2, where a flushing pipe interface 16 is provided. A negative pressure pipe connection hole 13 is provided below the flushing pipe connection hole 14. One end of the negative pressure pipe connection hole 13 is connected to the inside of the adjustment box 10, and the other end of the negative pressure pipe connection hole 13 penetrates the side wall of the handle 2. A negative pressure pipe interface 15 is provided at this location. In actual use, the other end of the hose connected to the rinsing machine is installed inside the rinsing pipe interface 16 and is sealed and connected to the rinsing pipe connection hole 14. The other end of the hose connected to the negative pressure machine is installed inside the negative pressure pipe interface 15 and is sealed and connected to the negative pressure pipe connection hole 13. Both sets of hoses are connected to the inside of the adjustment box 10. The end of the rinsing pipe connection hole 14 that is connected to the adjustment box 10 is flush with the inner wall of the adjustment box 10, while the end of the negative pressure pipe connection hole 13 that is connected to the adjustment box 10 protrudes a portion of the inner wall of the adjustment box 10 to cooperate with the structure of the conversion component 5.

[0036] like Figure 4 and Figure 5 As shown, the adjusting box 10 is a cylindrical structure closed at both ends. A connection port 12 is provided on the side wall of the adjusting box 10. The tail end of the sleeve 1 is embedded in the connection port 12 and fixedly connected to the handle 2. In actual operation, a sealing ring can be used between the sleeve 1 and the connection port 12 to increase the sealing at the connection. A connecting hole 11 is provided at the bottom of the adjusting box 10. The conversion component 5 is a cylindrical structure with a diameter smaller than the inner diameter of the adjusting box 10. Two sets of protrusions 17 are symmetrically provided on the side wall of the conversion component 5. Figure 5 The bump 17 shown is one set of bumps 17; another set of bumps is located at the rear. Figure 5 The structure of another set of bumps 17 could not be displayed. Figure 5 The set of protrusions 17 shown has the same structure. The protrusions 17 have an arc-shaped structure and are smoothly connected to the surface of the conversion component 5. The bottom of the conversion component 5 is fixedly connected to a turntable 20, and the bottom of the turntable 20 is fixedly connected to a corner block 21. When the conversion component 5 is installed inside the adjustment box 10, the turntable 20 extends to the outside of the adjustment box 10 through the connecting hole 11. The corner block 21 provided on the turntable 20 can be easily held by the operator, and the conversion component 5 can be rotated by holding the corner block 21.

[0037] The protruding part of the protrusion 17 is provided with a flushing through hole 18, which passes through the two sets of protrusions 17. The side wall of the conversion component 5 is provided with a T-shaped sliding groove 22, which surrounds the conversion component 5 and passes through the middle of the protrusion 17. One end of the flushing pipe 4 connected to the conversion component 5 is adapted to the structure of the sliding groove 22. The end of the flushing pipe 4 is embedded in the sliding groove 22 and slidably engaged with the conversion component 5. The lower part of the conversion component 5 is provided with a suction through hole 19, which passes through the conversion component 5. The channel formed by the flushing through hole 18 and the channel formed by the suction through hole 19 are perpendicular to each other. The maximum distance between the outward protruding parts of the two sets of protrusions 17 is the same as the inner diameter of the adjustment box 10, so that the outward protruding parts of the protrusions 17 contact the inner wall of the adjustment box 10. The height of the adapter 5 is the same as the internal height of the regulating box 10. When the adapter 5 is installed inside the regulating box 10, both ends of the adapter 5 abut against the inner walls of both ends of the regulating box 10, and the outward protrusion of the protrusion 17 is tangent to the inner wall of the regulating box 10. When the outward protrusion of the protrusion 17 contacts the inner wall of the regulating box 10, the flushing through hole 18 will be sealed by the inner wall of the regulating box 10. Specifically, the inner wall of the regulating box 10 has a variable diameter structure. The inner diameter of the regulating box 10 that contacts the outward protrusion of the protrusion 17 is large, and the inner diameter of the regulating box 10 that contacts the lower part of the adapter 5, which has the suction through hole 19, is small.

[0038] The working principle of this utility model is as follows:

[0039] In use, first, pass the flushing tube 4 through multiple sets of fixing rings 9 in sequence, and fix the suction tube 3 to the inner wall of the sleeve 1. Then, insert the tail end of the sleeve 1 into the connection port 12. The installed state should be that the head end of the flushing tube 4 is located near the flushing port 6, and the tail end of the flushing tube 4 is embedded in the sliding groove 22 and connected with the conversion part 5. The tail end of the suction tube 3 should be tightly attached to the side wall of the conversion part 5. Then, install two sets of hoses to the negative pressure pipe interface 15 and the flushing tube interface 16 respectively. The hose connected to the flushing tube interface 16 is connected to the flushing machine, and the hose connected to the negative pressure pipe interface 15 is connected to the negative pressure machine.

[0040] When using the irrigation function during surgery, the operator holds the handle of the handle 2 and pushes the corner block 21 with the index finger to rotate the conversion part 5. After the conversion part 5 rotates until the irrigation through hole 18 is fully aligned with the end port of the irrigation tube 4, the irrigation machine is connected to the irrigation tube 4. The irrigation fluid enters the irrigation tube 4 through the hose, the irrigation tube inlet 14, and the irrigation through hole 18, and then sprays out from the beginning port of the irrigation tube 4. When the irrigation through hole 18 is fully aligned with the end port of the irrigation tube 4, the protrusion 17 pushes the irrigation tube 4 towards the beginning and, guided by the baffle 8, extends from the irrigation port 6 to the outside of the sleeve 1, so that the water flow is directly sprayed to the outside of the sleeve 1 for easy irrigation.

[0041] When switching from the irrigation function to the suction function during surgery, the operator pushes the corner block 21 with their index finger to rotate the conversion element 5, so that the tail end of the suction tube 3 is fully aligned with the suction through hole 19. The negative pressure machine is connected to the suction tube 3, and the negative pressure machine forms a negative pressure vacuum at the head end of the suction tube 3. The waste in the surgical area is suctioned through the suction port 7 into the inside of the sleeve 1, and finally flows through the suction tube 3 through the negative pressure tube connection hole 13, and enters the liquid storage bottle carried on the negative pressure machine through the hose. At this time, due to the rotation of the conversion element 5, the irrigation through hole 18 is misaligned with the tail end of the irrigation tube 4, and the irrigation function stops.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the preferred embodiments; however, those skilled in the art can fully understand this utility model without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
