Description

Technical Field

[0001] The invention belongs to the field of medical instruments, and in particular relates to an electrocoagulation flushing and aspiration device. Background Art

[0002] With the development of modern medicine, minimally invasive surgery has become the development direction of surgical operations. Minimally invasive surgery has the characteristics of small trauma, fast recovery, less pain, and beautiful wounds. It is the common goal and direction pursued by modern medicine. Aspirators and laparoscopic electrocoagulators are two indispensable important instruments in surgical operations. The aspirator is used to absorb bleeding, exudates, pus, and contents of organs during surgery, and is responsible for revealing the surgical field of view and making the operation clear. The laparoscopic electrocoagulator mainly uses high-frequency current to electrocoagulate the bleeding openings of micro-vessels to stop bleeding. In existing laparoscopic abdominal surgery, after a tiny wound is cut in the abdominal skin, a puncture cannula is placed, the abdominal cavity is inflated, an abdominal cavity channel is established, and abdominal surgery is performed through the puncture cannula. The most commonly used surgical instrument is an electric hook. During the electrocoagulation process, water continuously flushes the tip of the electric hook, which can both weaken the adhesion of focal adhesion and dissipate heat. However, since dripping water during the electrocoagulation process will cause a certain interference with the field of vision, it is necessary to promptly remove the accumulated fluid during the operation. It is often necessary to use an aspirator and a laparoscopic electrocoagulation device simultaneously. Frequent replacement of surgical instruments will prolong the operation time. In addition, the operating space for minimally invasive surgery is small, and it is necessary to accommodate multiple instruments such as an endoscope, an aspirator, and a laparoscopic electrocoagulation device at the same time, which will increase the difficulty of the operation.

[0003] There are several problems with the existing electrocoagulation aspirators on the market: 1. The operating switch is complicated and unclear; 2. Flushing is controlled by hand, and electrocoagulation is controlled by foot, resulting in two operating methods for one instrument, hand and foot, which will cause inconvenience and misoperation, and in severe cases, serious damage to the body; 3. The design of the blade is unreasonable, and the head of the electrocoagulation hook is easily blocked by the external sheath, affecting the operation; 4. The push-pull action of the suction sheath is inconvenient, and even requires two-handed operation. Such operation reduces the advantage of "two in one"; 5. The handle does not conform to ergonomics and is not flexible to operate; 6. The most practical action during the operation is "scraping and suction", which cannot be achieved with this blade design; 7. The pipes extending from the bottom will affect the operator's operating space. For example, the gun-type electrocoagulation medical device with patent number CN201721286596.1 authorized on June 4, 2019 includes a conductive rod, an insulating tube is provided on the outer periphery of the conductive rod, an electrocoagulation working head is provided at the front end of the conductive rod, and the electrocoagulation working head extends out of the front end of the insulating tube, and is characterized in that a gun-type handle is provided at the rear end of the conductive rod, the rear end of the insulating tube extends to the gun-type handle, and a circuit structure electrically connected to the conductive rod is provided in the gun-type handle. However, this technical solution lacks a flushing device, and an additional flushing device is still required during the operation, which is rather troublesome. At the same time, this technical solution uses the same switch for negative pressure suction and electrocoagulation and electrocuting. Although a large amount of smoke generated during electrocoagulation and electrocuting can be discharged in time through the negative pressure suction pipeline, when electrocoagulation and electrocuting are not in use, the suction device cannot be used to remove the accumulated fluid during the operation, so the function is limited and the operation is inconvenient. Summary of the invention

[0004] In summary, in order to overcome the deficiencies of the prior art, the present invention provides an electrocoagulation flushing and aspiration device that is simple to operate and easy to use.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electrocoagulation flushing and aspiration device, comprising a handle, a conductive rod is provided at the front end of the handle, an insulating tube is provided on the outer periphery of the conductive rod, an electrocoagulation working head is provided at the front end of the conductive rod, the electrocoagulation working head extends out of the front end of the insulating tube, a suction and flushing device and an electrocoagulation and electric cutting device are provided in the handle, the conductive rod is hollow, a conductive part for connecting to the electrocoagulation and electric cutting device and a connecting part for connecting to the suction and flushing device are provided at the rear end of the conductive rod, the conductive part is provided between the connecting part and the insulating tube, and the conductive part is electrically connected to the electrocoagulation and electric cutting device.

[0006] By adopting the above technical scheme, compared with the prior art, the technical scheme of the present invention integrates electrocoagulation, flushing and suction into one, has strong functionality, and the integration of the instrument is conducive to one-handed operation, without the need to use hands and feet or both hands to operate, which is more convenient for surgical operations and reduces surgical risks. At the same time, electrocoagulation, flushing and suction all use the same conductive rod to work, without the need for double tubes, which will not cause line of sight obstruction and is more convenient for "scraping and suction" operations.

[0007] The present invention is further provided that: the suction and flushing device includes a negative pressure suction mechanism, a flushing mechanism and a connecting mechanism, the connecting mechanism includes a four-way connecting piece, the four-way connecting piece includes a first connecting pipe for connecting to the connecting part, a second connecting pipe for connecting to the flushing mechanism and a third connecting pipe for connecting to the negative pressure suction mechanism, the first connecting pipe is connected to the second connecting pipe in a flushing mode, the first connecting pipe is connected to the third connecting pipe in a suction mode, and the flushing mode and the suction mode are alternately performed.

[0008] By adopting the above technical scheme, the flushing mode and the suction mode in the technical scheme of the present invention are alternately performed, and the flushing mode and the suction mode cannot exist at the same time. In the case of no operation, it is generally in the suction mode, that is, the first connecting pipe and the third connecting pipe are in a connected state, and the second connecting pipe is in a closed state. When the negative pressure suction mechanism is opened, the electrocoagulation flushing and suction device is in the suction state. When the negative pressure suction mechanism is not operated, the electrocoagulation flushing and suction device stops suction. When the flushing mechanism is operated to open and the four-way connector is changed to the flushing mode, that is, the first connecting pipe and the second connecting pipe are in a connected state, and the third connecting pipe is in a closed state, at this time, water flows through the first connecting pipe and the second connecting pipe into the conductive rod and flows to the electrocoagulation working head. When the flushing mechanism is not opened, the four-way connector is reset to the suction mode. The negative pressure suction double switch enhances safety, but one layer of the switch is in a normally open state, which is simple to operate. At the same time, the flushing function is turned on and the suction function is turned off by the same switch to ensure that the two are not performed at the same time, thereby increasing the safety of the operation.

[0009] The present invention is further provided that: the negative pressure suction mechanism includes a pressing and suction component and a continuous suction component, the third connecting pipe includes a first connecting port and a second connecting port, the first connecting port is connected to the pressing and suction component, the second connecting port is connected to the continuous suction component, the rear end of the handle is provided with a suction connecting piece for connecting to a negative pressure device, and the pressing and suction component and the continuous suction component are both connected to the suction connecting piece.

[0010] By adopting the above technical scheme, the negative pressure suction in the technical scheme of the present invention is divided into two parts, which are respectively realized through the first connection port or the second connection port. When short-term suction is required, it is only necessary to press and open the press suction component to realize negative pressure suction. However, sometimes negative pressure suction is required for a long time, and the hands are prone to fatigue and cramps, which affects the operation. Therefore, a continuous suction component is provided. It is only necessary to turn on the continuous suction component without continuous operation of the hands to realize continuous negative pressure suction. Different operations can be performed according to different needs. It has strong functionality, is easy to operate, and saves effort.

[0011] The present invention is further provided that: the press-and-suction component includes a first suction member, the first suction member is hollow, the first suction member is provided with a third connection port for connecting to the first connection port, and a fourth connection port for connecting to the suction connection member, the press-and-suction component also includes a first opening and closing member for opening and closing the third connection port and an operating member for driving the first opening and closing member to move, an elastic member for resetting the first opening and closing member is provided between the first opening and closing member and the operating member, the first opening and closing member is provided with a circulation channel, and an opening is provided on a side of the first opening and closing member corresponding to the third connection port, and the opening is communicated with the circulation channel.

[0012] By adopting the above technical scheme, the pressing operating member drives the first opening and closing member to move, so that the opening of the first opening and closing member is aligned with the third connecting port, and the third connecting port is connected to the fourth connecting port through the circulation channel in the first opening and closing member, that is, the pressing and suction component is opened, one end of the suction connecting member is connected to the negative pressure suction device, and the other end is connected to the first suction member in the handle through the fourth connecting port, and then passes through the circulation channel through the third connecting port, and is connected to the first connecting port of the four-way connecting member through a pipeline connection. At this time, the four-way connecting member is in an suction state, that is, the first connecting pipe and the third connecting pipe are in a connected state, and then connected to the conductive rod through the four-way connecting member, and negative pressure suction starts at this time, but an elastic member for resetting the first opening and closing member is arranged between the first opening and closing member and the operating member. When released, the elastic member drives the first opening and closing member to reset, so that the opening of the first opening and closing member is staggered with the third connecting port, that is, the negative pressure suction stops, and the operation is simple and convenient.

[0013] The present invention is further provided with: a fifth connection port is also provided on the first attraction member, the continuous attraction component includes a second attraction member, the second attraction member is hollowly arranged, the second attraction member is provided with a sixth connection port for connecting with the second connection port, and a seventh connection port for connecting with the fifth connection port, the fifth connection port is communicated with the fourth connection port, and the second attraction member is connected with the attraction connection member through the first attraction member.

[0014] By adopting the above technical solution, the second attraction member is connected to the fifth connection port of the first attraction member, and the fifth connection port is always in a connected state with the fourth connection port, that is, the second attraction member is connected to the attraction connection member through the channel in the first attraction member, and the two sets of pipelines are combined into one set, which simplifies the structure and reduces the cost.

[0015] The present invention further provides: the continuous attraction component also includes a connecting piece and a rotating switch for connecting the sixth connection port with the seventh connection port, the connecting piece is arranged in the second attraction member, the connecting piece includes a first connecting port and a second connecting port, the rotating switch drives the connecting piece to rotate so that the first connecting port and the second connecting port of the connecting piece are aligned or staggered with the sixth connection port and the seventh connection port respectively.

[0016] By adopting the above technical solution, the connecting piece is driven to rotate by rotating the rotary switch, so that the first connecting port and the second connecting port of the connecting piece are aligned with the sixth connecting port and the seventh connecting port respectively, that is, the continuous suction function is turned on, and then the rotary switch is driven to rotate the connecting piece, so that the second connecting port of the connecting piece is staggered with the seventh connecting port (it can only be turned on if the two connecting ports are aligned, and the continuous suction function cannot be turned on if any of the connecting ports is staggered), that is, the continuous suction function is turned off. The technical solution of the present invention can free fingers to operate when continuous suction and smoking are required.

[0017] The present invention is further provided that: an operating component for starting the flushing mode is provided at the position of the handle corresponding to the four-way connecting piece, the four-way connecting piece is provided in an X-shape, the four-way connecting piece also includes a fourth connecting pipe for being connected to the operating component, the operating component includes a pressing piece provided outside the handle, a second opening and closing piece provided in the fourth connecting pipe and an elastic piece for resetting the second opening and closing piece, the pressing piece is connected to the second opening and closing piece, the second opening and closing piece is adapted to the fourth connecting pipe, a connecting channel for connecting the first connecting pipe and the second connecting pipe is obliquely provided on the second opening and closing piece, the pressing piece drives the second opening and closing piece to move downward along the fourth connecting pipe until the two ends of the connecting channel are respectively aligned with the first connecting pipe and the second connecting pipe, and the angle between the fourth connecting pipe and the second connecting pipe is smaller than the angle between the fourth connecting pipe and the first connecting pipe.

[0018] By adopting the above technical solution, pressing the pressing piece drives the second opening and closing piece to move downward along the fourth connecting pipe until the two ends of the connecting channel are respectively aligned with the first connecting pipe and the second connecting pipe. Even if the four-way connecting piece is changed to the flushing mode, when the pressing piece is released, since the four-way connecting piece is arranged in an X shape, the angle between the fourth connecting pipe and the second connecting pipe is smaller than the angle between the fourth connecting pipe and the first connecting pipe. Therefore, when the second opening and closing piece is reset, the second opening and closing piece is tilted upward. At this time, the second opening and closing piece blocks the second connecting pipe but does not block the first connecting pipe. At the same time, the second opening and closing piece retreats from the third connecting pipe to the fourth connecting pipe. At this time, the third connecting pipe is connected to the first connecting pipe.
