[0045] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] This embodiment provides an auxiliary feeding device for a cavity flushing and exploration tube body. Figure 1 It is a schematic structural diagram of this embodiment, as Figure 1 shown, including a pushing component 1 and a detection structure 2 arranged on one side of the pushing component 1.

[0047] Among them, the pushing component 1 at least includes a hollow main body 11 and a push rod 12 arranged in the main body 11, and the push rod 12 is used to slide in the main body 11.

[0048] In this embodiment, a damping member 3 is arranged between the main body 11 and the push rod 12. Figure 2 It is a schematic structural diagram of the damping member in this embodiment, as Figure 2 shown, the damping member 3 adopts an annular structure with one side open, and in actual use, materials such as rubber, silica gel, and metal, such as copper, can be selected. Anti-slip structures can also be arranged on its surface according to actual use needs.

[0049] Figure 3 Is Figure 1 a cross-sectional structural diagram of, as Figure 3 shown, the damping member 3 is arranged at the end of the main body 11 and is located between the main body 11 and the push rod 12. An installation groove 115 for the damping member 3 is arranged at the end of the main body 11. The installation groove 115 is used for axially limiting the damping member 3 to avoid problems such as the damping member 3 running off during use, so as to improve the stability during use.

[0050] By arranging the damping member 3 at the end of the main body 11, it can be adjusted through the damping member 3 according to the actual use environment, so that the sliding speed of the push rod 12 in the main body 11 is controllable. The push rod 12 can slide relatively slowly in the main body 11, avoiding the problem that when the friction between the push rod 12 and the main body 11 is small, the pushing force is not easy to control, resulting in the tube body extending too fast and too long, causing harm to the patient.

[0051] A first cavity 20 is arranged in the detection structure 2, a second cavity 120 communicating with the first cavity 20 is arranged in the push rod 12, and the tube body extends from the second cavity 120 into the first cavity 20. During use, the tube body extends out from the end of the first cavity 20 and enters the human body cavity.

[0052] Specifically, a scale 10 is provided on the pushing component 1, so that the depth of the tube body extending into the internal cavity can be accurately known, improving the controllability of the operation.

[0053] During clinical use, the tube body generally uses a flexible tube. During installation, the end of the tube body is flush with the end of the detection structure. By using this cavity flushing and exploration tube body auxiliary feeding device, the detection structure 2 assists the tube body to reach the cavity opening of the human body, and then slides inward into the main body 11 through the push rod 12. The sliding of the push rod 12 drives the tube body placed inside the push rod 12 into the internal cavity. In cooperation with the scale 10 provided on the pushing component 1, the depth of the tube body entering the cavity can be known, so as to increase the controllability and accuracy of the operation and improve the operation efficiency. And by adjusting the damping member 3, the speed of the tube body sliding in the main body 11 along with the push rod 12 can be controlled, thus effectively avoiding the problem that the tube body extends too fast and too long, causing harm to the patient.

[0054] As an optional implementation manner, Figure 4 is the structural schematic diagram of the main body in this embodiment, as Figure 4 shown, a groove structure 110 is further provided on the main body 11.

[0055] Specifically, in this embodiment, the main body 11 adopts a hollow columnar structure. The groove structure 110 is opened on the side wall of the main body 11 along one end of the main body 11, and the other end of the groove structure 110 is set as an arc-shaped structure. The groove structure 110 is communicated with the inside of the main body 11 and is arranged along the length direction of the main body 11.

[0056] Figure 5 is the structural schematic diagram of the push rod in this embodiment, as Figure 5 shown, the push rod 12 adopts a columnar rod with a circular cross-section. During use, the push rod 12 is arranged in the hollow structure of the main body 11. A convex block 121 is provided on the push rod 12. The convex block 121 adopts a rounded rectangular structure and is integrally formed or fixedly connected with the push rod 12 and is located on the surface of the push rod 12. The convex block 121 cooperates with the groove structure 110 for sliding along the groove structure 110.

[0057] By providing the groove structure 110 on the surface of the main body 11 and cooperating with the convex block 121 provided on the push rod 12, the push rod 12 is limited, preventing the push rod 12 from rotating in the main body 11. The stability of the push rod 12 when sliding along the main body 11 is better.

[0058] Figure 6 is Figure 5 the cross-sectional structural schematic diagram of Figure 6As shown, the second cavity 120 is disposed at the center of the push rod 12. The second cavity 120 includes a first section 1201, a second section 1202, and a third section 1203 that are sequentially arranged with gradually decreasing diameters. The third section 1203 is close to the detection structure 2, and the diameter of the third section 1203 is the same as the diameter of the first cavity 20, facilitating the installation and pushing operations of the tube body.

[0059] Since the tube body is relatively thin, in this embodiment, a stepped tube body is adopted, and the tube body on the side away from the detection structure 2 is thicker, which is beneficial to increasing the strength of the overall structure and facilitating the smooth feeding of the tube body into the human body cavity.

[0060] In actual use, the second cavity 120 can also be set in other structural forms to adapt to the tube body structure therein.

[0061] As an optional implementation manner, the scale 10 is disposed on both sides of the groove structure 110 and on the surface of the main body 11. During use, by checking the sliding distance of the convex block 121 along the groove structure 110, the depth of the tube body extending into the human body cavity can be directly seen, so as to improve the accuracy of the operation, reduce the workload of medical staff, and relieve the pain of patients.

[0062] Alternatively, the scale 10 can also be disposed on the surface of the push rod 12. By checking the length of the push rod 12 extending into the main body 11, the depth of the tube body extending into the human body cavity can be directly seen, so as to improve the accuracy of the operation, reduce the workload of medical staff, and relieve the pain of patients.

[0063] As an optional implementation manner, Figure 7 is a schematic structural diagram of the detection structure in this embodiment. As Figure 7 shown, the detection structure 2 includes a detection main body 21 and a connecting body 22 disposed on one side of the detection main body 21. An insertion end 221 and a flange 222 located on the outer periphery of the insertion end 221 are disposed at the end of the connecting body 22.

[0064] Figure 8 is Figure 7 a cross-sectional structural diagram of Figure 8 As shown, the first cavity 20 is disposed in the detection main body 21, and a connecting cavity 220 communicating with the first cavity 20 is disposed in the connecting body 22, and the connecting cavity 220 is conical.

[0065] As Figure 3 shown, the insertion end 221 extends into the interior of the main body 11, and a stop position 114 is disposed inside the main body 11; the flange 222 abuts against the end of the main body 11, and the outer diameter of the flange 222 is the same as the outer diameter of the end of the main body 11.

[0066] By setting the detection structure 2 to include a connector 22, and an insertion end 221 is provided at the end of the connector 22, and the insertion end 221 is arranged inside the main body 11. When the end of the main body 11 is connected to the damping member 3, the connection tightness adjustment and locking of the end of the detection structure 2 can be carried out through the damping member 3, which is convenient for the installation of the pipe body.

[0067] In this embodiment, the detection part of the detection main body 21 is made of titanium alloy material. Utilizing the advantage of the strong plasticity of the titanium alloy material itself, the detection main body 21 has the advantage of being adjustable. The angle of the detection main body 21 can be effectively adjusted according to different individuals and different channel environments, so as to make the detection main body 21 more suitable for the user, make the operability of this channel flushing and exploration pipe body auxiliary feeding device stronger, reduce the pain of the user, improve the treatment efficiency, and reduce the burden on medical staff.

[0068] Of course, in actual use, the detection main body 21 can also be made of other existing metal or non-metal materials with strong plasticity on the market, which can avoid adverse reactions with the human body during use, and have good plastic effects and are convenient for adjustment.

[0069] As an optional implementation manner, a first connection structure 111 and a second connection structure 112 are respectively arranged at both ends of the main body 11.

[0070] Wherein, a first fastener 61 and a second fastener 62 are respectively connected at the first connection structure 111 and the second connection structure 112. The first fastener 61 and the second fastener 62 are respectively used to adjust the connections between the main body 11 and the detection structure 2, and between the main body 11 and the push rod 12, and are also used for locking.

[0071] Specifically, in this embodiment, the first connection structure 111 and the second connection structure 112 respectively adopt a first thread structure, and second thread structures matching the first thread structure are arranged on both the first fastener 61 and the second fastener 62. The threaded structure is used for mating connection, which is convenient for operation and has better connection stability.

[0072] Moreover, anti-slip structures are arranged on the outer surfaces of the first fastener 61 and the second fastener 62 in this embodiment, so as to increase the friction with the hands of the operator and make the tightening adjustment more convenient.

[0073] Since a damping member 3 made of an elastic material and having an opening on one side is arranged inside the second fastener 62, by adjusting the second fastener 62 and cooperating with the action of the damping member 3, the push rod 12 can drive the pipe body inside it to slide in the main body 11 at an appropriate speed, and the controllability is stronger.

[0074] As an alternative embodiment, it further includes a gripping member 4, which is arranged on the pushing assembly 1 and is used for the doctor to hold the gripping member by hand during operation for easy operation.

[0075] In this embodiment, the gripping member 4 at least includes a first gripping portion 41, a second gripping portion 42 and a third gripping portion 43, which are used for gripping by the thumb, index finger and middle finger during use.

[0076] Specifically, both the first gripping portion 41 and the second gripping portion 42 are arranged on the main body 11 and are symmetrically arranged along the main body 11, and the third gripping portion 43 is arranged on the push rod 12.

[0077] Among them, the first gripping portion 41, the second gripping portion 42 and the third gripping portion 43 are all in a circular ring shape. By adopting the circular ring structure, it is convenient to accommodate the fingers and the operation is convenient.

[0078] Of course, in actual production and use, the first gripping portion 41, the second gripping portion 42 and the third gripping portion 43 can also be set to adopt other structures according to actual use requirements, such as: other regular or irregular shapes such as oval, rounded rectangle, square, etc., as long as it is convenient for the fingers to extend in and out and for gripping.

[0079] As an alternative embodiment, it further includes a first fixing member 51 and a second fixing member 52.

[0080] Among them, the surface of the main body 11 is provided with a first fixed connection position 113 that communicates with the inside of the main body 11, and the first fixing member 51 is connected to the first fixed connection position 113 for fixing the push rod 12 and the main body 11. When the push rod 12 extends into the main body 11 to a certain depth and meets the use requirements, the push rod 12 and the main body 11 can be locked by the first fixing member 51.

[0081] Specifically, in this embodiment, the first fixed connection position 113 protrudes from the surface of the main body 11, and a threaded structure is arranged inside the first fixed connection position 113.

[0082] Of course, a threaded hole can also be directly opened on the main body 11. By setting the first fixed connection position 113 to protrude from the main body 11, the problem of the thin side wall of the main body 11 can be avoided, and the connection stability between the first fixing member 51 and the main body 11 is stronger.

[0083] The surface of the push rod 12 is provided with a second fixed connection position 122 that communicates with the inside of the push rod 12, and the second fixing member 52 is connected to the second fixed connection position 122 for fixing the push rod 12 and the tube body.

[0084] Specifically, in this embodiment, the surface of the push rod 12 is provided with a first section 1201 of a second cavity 120 provided inside the push rod 12, which is used to fix the push rod 12 and the tube body provided inside it.

[0085] Similar to the first fixed connection position 113, a second fixed connection position 122 is provided protruding from the surface of the push rod 12, and a threaded structure is provided inside the second fixed connection position 122 to avoid the problem of the thin side wall of the push rod 12, making the connection stability between the second fixing member 52 and the push rod 12 stronger. Of course, a threaded hole can also be directly formed in the push rod 12.

[0086] During use, other structures for drug injection and flushing are connected to the tube body for cavity flushing operations.

[0087] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
