Description

Technical Field

[0001] The present invention relates to a medical device, in particular to an auxiliary device for wound cleaning used in minimally invasive surgery, specifically a disposable electric irrigation and aspiration tube. Background Art

[0002] The irrigation and aspiration catheter is an essential auxiliary device in minimally invasive surgery and is for single use. It is mainly used to clean the wound in time during the operation to ensure the clarity of the surgical field and to aspirate and discharge the waste liquid and residual tissue generated during the operation out of the body in time to prevent wound contamination. At present, the following disadvantages mainly exist in the existing surgical irrigation and aspiration devices on the market: on the one hand, the irrigation mainly relies on gravity to provide pressure. When the height of the irrigation saline bottle is insufficient or the amount of saline in the bottle is insufficient, the irrigation pressure will be insufficient, and the effect of irrigating the wound surface is not good. Sometimes, it even needs to rely on medical staff to hold it by hand or use a pressure boosting bag to increase the pressure, which is very inconvenient to use. On the other hand, the aspiration mostly relies on the hospital's own negative pressure source to generate suction force. In some special situations, such as when there is no negative pressure source or the negative pressure source is damaged due to power failure or war damage, the negative pressure aspiration during the minimally invasive surgery cannot be achieved, which will affect the normal progress of the operation. Attention must be paid to this and solved to overcome the defects in the existing technology for emergencies. Chinese patents 2016102998488 and 2022111200400 both disclose an electrocoagulator with an irrigation and aspiration catheter. Although it solves the problem of the integration of electrocoagulation and irrigation and aspiration, it still cannot independently solve the problems of irrigation pressure and negative pressure aspiration source failure during use. Summary of the Invention

[0003] The purpose of the present invention is to design a disposable electric irrigation and aspiration tube to solve the problem of insufficient irrigation pressure due to the reliance on gravity for the existing irrigation and aspiration catheter. It can not only solve the problem of insufficient irrigation pressure but also provide negative pressure aspiration under stress conditions to solve the problem of inoperability due to the absence of a negative pressure source or negative pressure damage.

[0004] The technical solution of the present invention is as follows:

[0005] A disposable electric flushing and suction tube, comprising a handle 1 and a flushing and suction tube 2, characterized in that a diaphragm pump 3 with a lithium battery is installed in the handle 1, an inlet three-way joint 4 and an outlet three-way joint 5 are installed on the diaphragm pump 3, one inlet end of the inlet three-way joint 4 is communicated with a physiological saline interface 7 on the handle through a first flushing connecting tube 6, the other inlet of the inlet three-way joint 4 is communicated with the first port of a flushing and suction three-way joint 9 installed in the handle 1 through a first suction connecting tube 8, and the outlet end of the inlet three-way joint 4 is communicated with the inlet end of the diaphragm pump 3; the inlet end of the outlet three-way joint 5 is communicated with the diaphragm pump 3, one outlet end of the outlet three-way joint 5 is connected with the second port of the flushing and suction three-way joint 9 through a second flushing connecting tube 10, and the other outlet end of the outlet three-way joint 5 is communicated with a waste liquid and negative pressure interface 11 installed on the handle 1 through a second suction connecting tube 10; the third port of the flushing and suction three-way joint 9 is directly or indirectly communicated with one end of the flushing and suction tube 2 fixed in the handle.

[0006] A filter net 12 is installed in the flushing and suction tube 2.

[0007] A flushing button 13 and a suction button 14 are also installed on the handle 1.

[0008] A three-way adjusting lever 15 is also installed on the handle 1 to control the simultaneous conduction and closing of the first flushing connecting tube 6 and the second flushing connecting tube 10 and the simultaneous conduction and closing of the first suction connecting tube 8 and the second suction connecting tube 10.

[0009] Advantages of the present invention:

[0010] By means of the diaphragm pump, the present invention realizes flushing pressurization and solves the problem of normal flushing and suction under extreme conditions and without negative pressure, which is applicable to both normal surgical operations and emergency use during wartime.

[0011] The present invention creatively changes the traditional one-way pump into a two-way pump, realizing multiple functions with one pump.

[0012] The present invention is powered by a battery, solving the problem of normal use under emergency conditions.

[0013] The present invention can be widely applied to various minimally invasive surgical instruments to realize pressurized cleaning and negative pressure suction.

[0014] The present invention integrates an electric pump and a power supply battery in the handle, which not only simplifies the structure but also ensures the flushing pressure. Under normal negative pressure suction conditions, only electric pressurization is needed to ensure the normal progress of flushing, making the surgical field of view clear. At the same time, if the negative pressure suction is interrupted during the operation or the negative pressure suction function of the present invention is immediately turned on, it can ensure that the waste materials during the operation are promptly cleared from the human body. Description of the Drawings

[0015] Figure 1 This is a schematic structural diagram of the present invention. Detailed implementation mode

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] As Figure 1 shown.

[0018] A disposable electric flushing and suction tube includes a handle 1 and a flushing and suction tube 2, and a filter net 12 is installed in the flushing and suction tube 2. A diaphragm pump 3 with a lithium battery (model: JT-DC3W-3.7) is installed in the handle 1. An inlet three-way joint 4 and an outlet three-way joint 5 are installed on the diaphragm pump 3. One inlet end of the inlet three-way joint 4 is communicated with a physiological saline interface 7 on the handle through a first flushing connecting tube 6 (physiological saline is input into the diaphragm pump through this interface). The other inlet of the inlet three-way joint 4 is communicated with the first port of a flushing and suction three-way joint 9 installed in the handle 1 through a first suction connecting tube 8. The outlet end of the inlet three-way joint 4 is communicated with the inlet end of the diaphragm pump 3. The inlet end of the outlet three-way joint 5 is communicated with the diaphragm pump 3. One outlet end of the outlet three-way joint 5 is connected to the second port of the flushing and suction three-way joint 9 through a second flushing connecting tube 10. The other outlet end of the outlet three-way joint 5 is communicated with a waste liquid and negative pressure interface 11 installed on the handle 1 through a second suction connecting tube 10 (the negative pressure for adsorption is sent into the flushing and suction tube 2 through this interface, and the waste liquid and waste residues generated by adsorption are sent into a waste liquid bag through this interface, and its structure and connection method are the same as those of the prior art). The third port of the flushing and suction three-way joint 9 is directly or indirectly connected to the end of the flushing and suction tube 2 fixed in the handle. As Figure 1 shown, a flushing button 13, a suction button 14 and a three-way adjusting lever 15 are also installed on the handle 1 to control the simultaneous conduction and closing of the first flushing connecting tube 6 and the second flushing connecting tube 10 and the simultaneous conduction and closing of the first suction connecting tube 8 and the second suction connecting tube 10.

[0019] Details are as follows:

[0020] The present invention can be widely used for flushing the wound surface during surgery and extracting the waste liquid generated during surgery. Its structure is shown in Figure 1. When the flushing button 13 is pressed, the diaphragm pump 3 starts to start, and the physiological saline in the saline bag is drawn into the diaphragm pump through the first flushing connection tube 61 through the inlet tee 4 at the inlet of the diaphragm pump 3, and the physiological saline is output from the outlet tee 5 at the outlet of the diaphragm pump 3, and finally sprayed out through the second flushing connection tube 10 and the flushing suction tube 2. At this time, the first suction connection tube 8 and the second suction connection tube 10 are in a closed state; when the suction button 14 is pressed, the waste liquid is drawn into the diaphragm pump 3 through the flushing suction tube 2, each inlet tee 4, and the first suction connection tube 81, and the waste liquid is output through the outlet tee 5 on the diaphragm pump, and the waste liquid is output to the waste liquid bag through the second suction connection tube 10, and the first flushing connection tube 6 and the second flushing connection tube 10 are closed. The switching of the first flushing connection tube 6, the second flushing connection tube 10 and the first suction connection tube 8, the second suction connection tube 10 is switched by the three-way adjustment gear 15 on the upper part of the handle. That is, when the three-way adjustment gear 15 is in position 1, the second flushing connection pipe 6 and the second flushing connection pipe 10 are connected, and the first suction connection pipe 8 and the second suction connection pipe 10 are closed. When the three-way adjustment gear 15 is in position 2, the opposite is true. There is a filter 12 in the flushing suction pipe 2, which can filter out the residue in the waste liquid to ensure that the rear-end pipeline is not blocked. When the residue in the filter reaches a certain level, the residue can be washed away by physiological saline. In specific implementation, the three-way adjustment gear 15 can simultaneously control the direction of the two three-ways through the connecting rod mechanical structure to realize the opening and closing of the corresponding pipeline.

[0021] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art.
