Examples:

the handle gun in the preferred embodiment of the invention is mainly applied to the operation process of doctors and is used for carrying out water flushing and/or water suction on the operation wound surface, and comprises a shell 1 in a 'pistol' form, so that a user can hold and control the handle gun with one hand conveniently. Meanwhile, a receiving chamber is formed in the housing 1, and at least one pipe is provided therein for the transportation of water. It is to be understood that the "water-liquid feeding" may be to suck and discharge the water liquid in the working area, or may be to feed the water liquid outside to the working area, which may be preferable according to the actual situation.

In a preferred embodiment, the pipeline in the shell 1 comprises a suction pipeline which can realize suction and discharge of water in the working area, and the handle gun has at least a suction function and can be called as a suction handle gun. Of course, when there is only one pipeline, the pipeline can also meet other functional requirements, for example, the pipeline can be a flushing pipeline, so as to meet the flushing requirement.

In another embodiment, at least two pipelines are arranged in the shell 1, and each pipeline is arranged independently of the other, so that corresponding working and using processes can be completed respectively. Moreover, it will be understood that when the pipelines are provided in plural, the functions between the plural pipelines may be the same or different, for example, two suction pipelines are provided simultaneously to satisfy the suction requirements under different conditions, or one suction pipeline and one flushing pipeline are provided simultaneously to respectively complete the suction requirements and the flushing requirements, which may be preferable according to the actual requirements, and will not be described herein.

In the preferred embodiment shown in fig. 1 to 15, two pipes, namely a first pipe 2 and a second pipe 3, are provided in the housing 1, which will be described in detail later as an example.

Specifically, the housing 1 in the preferred embodiment includes a first housing 101 and a second housing 102, which are preferably made of medical grade plastic materials, are safe and harmless and are lightweight, ensuring that no significant hand fatigue occurs with long-term gripping by the user. It will be understood that the two shells are respectively formed with a containing cavity, and after the two shells are spliced, a complete cavity for containing the two pipelines is formed, and the two pipelines are isolated from the external environment of the shell 1.

Meanwhile, a double-cavity tube 4 is preferably arranged at the muzzle part of the shell 1 and is correspondingly communicated with one ends of two pipelines, so that when the handle gun is actually used, the end part of the double-cavity tube 4 directly acts on an operation area (namely, the part in operation which needs flushing and suction); correspondingly, an external pipeline is correspondingly arranged at the bottom of the grab handle of the shell 1 and is used for being communicated with the other ends of the two pipelines, so that pumping of flushing liquid and sucking of sucking liquid are completed. Accordingly, a double-lumen tube screw cap 103 is provided at the end of the housing 1, as shown in fig. 1, for fixing the double-lumen tube 4 communicating the two pipes at the "muzzle" position of the housing 1, ensuring reliable setting of the double-lumen tube 4. Of course, it will be appreciated that by providing the dual lumen threaded cap 103, locking of the ends of the first housing 101 and the second housing 102 may also be achieved such that the two housings secure the ends of the dual lumen tube 4.

For the dual lumen tube 4 of the embodiment, two separate lumens are formed therein for performing the fluid communication process accordingly. In the preferred embodiment, the two lumens of the double-lumen tube 4 are an irrigation lumen and a suction lumen respectively, and the delivery process of the irrigation water at the operation port and the suction process of the water after irrigation, the tissue fluid in the operation and the like are independently completed.

Further, for the first pipe 2 in the preferred embodiment, it is preferable that the flushing pipe includes a first connection pipe 201, a control pipe 202 and a second connection pipe 203 which are sequentially communicated. Wherein, one end of the first connecting pipe 201 is communicated with one end of the control pipe 202, and the other end is communicated with the flushing pipe cavity in the double-cavity pipe 4; accordingly, one end of the second connecting tube 203 is communicated with one end of the control tube 202, and the other end is communicated with the first external connecting tube 5, and the water for irrigation is introduced into the wound surface during operation through the first external connecting tube 5.

In order to realize on-off control and flow control of the first pipeline 2, a control component is arranged in the shell 1 corresponding to the control pipe 202.

In more detail, the control assembly in the preferred embodiment is shown in fig. 8 to 11, which includes a fixed base plate 205, a movable plate 206, and a pair of line clamping plates 211 provided on one side of the movable plate 206 near the control tube 202. In order to realize displacement guiding and limiting of the movable plate 206, guide blocks are arranged in pairs on the fixed bottom plate 205, as shown in fig. 2, so that the movable plate 206 can be just embedded between the two guide blocks and can reciprocate between the two guide blocks, and then the movable plate is close to or far from the control tube 202 arranged on one side of the end part of the movable plate 206. In the preferred embodiment, the opposing side wall surfaces of the guide blocks are disposed in parallel with a spacing therebetween just equal to the width of the movable plate 206. Meanwhile, the inner sides of the end parts of the two guide blocks, which are close to the control tube 202, are respectively provided with a wedge-shaped structure, the two wedge-shaped structures are symmetrically arranged, and a horn mouth shape is formed at the end parts of the two guide blocks. In addition, the pipe clamping plate 211 is hinged at one end thereof to the end of the movable plate 206 and is rotatable with respect to the end.

Accordingly, in order to cooperate with the two pipe clamping plates 211, the control pipe 202 in the preferred embodiment is bent in a ring shape as shown in fig. 9, and its end portion communicating with the two connection pipes is locked to the end portion of the fixing base plate 205 by one block, as shown in fig. 8 to 11. At this time, the two line clamps 211 are respectively provided at both sides of the outer circumference of the annular control tube 202.

It will be appreciated that when the connection portion of the pipe clamping plates 211 is opposite to the corresponding wedge surface, the two pipe clamping plates 211 can be rotated to a position where they are attached to the corresponding wedge surface, at this time, the opening angle between the two pipe clamping plates 211 is the largest, and the control pipe 202 can be opened to be in a ring structure. When the movable plate 206 moves between the two guide blocks away from the control tube 202, the two line clamping plates 211 are pulled between the two guide blocks. At this time, the two pipe clamping plates 211 are switched from the "open state" to the "closed state", the space between the two pipe clamping plates is greatly reduced, one end of the annular control pipe 202 is clamped by the two pipe clamping plates 211, the annular control pipe is switched to the "flat state" by the "annular state", the middle part of the control pipe 202 is extruded and bent, and the communication of the control pipe 202 is blocked.

It is also clear that, when the movable plate 206 moves close to the control tube 202, the hinged ends of the two pipe clamping plates 211 can move from the opposite wall surfaces of the two guide blocks to the positions corresponding to the two wedge surfaces, at this time, the expandable angle between the two pipe clamping plates 211 becomes large, and if the first pipe 2 is filled with a liquid with a certain water pressure, the control tube 202 is restored to be annular, so that the first pipe 2 is communicated.

Preferably, in order to ensure the reliability of the clamping and recovery of the control tube 202, the material is preferably selected, and particularly preferably a tubular structure made of a material such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), polycarbonate (PC), ABS, polyurethane, polyamide, thermoplastic elastomer, polysulfone, and polyetheretherketone, which is a medical tube having high elasticity.

Obviously, it can be further understood that through the arrangement of the control component, not only the on-off control of the first pipeline 2 can be realized, but also the flow and the water pressure in the first pipeline 2 can be correspondingly adjusted. Because of the movement of the movable plate 206, the angle clamped between the two pipeline clamping plates 211 can be continuously adjusted, so that the clamping angle of the movable plate to the control pipe 202 can be continuously adjusted, and the control pipe 202 can be correspondingly clamped and deformed in the middle of the annular pipeline, thereby adjusting the flow in the first pipeline 2 and the water pressure of flushing, and meeting different use requirements.

Further, a locking mechanism is provided in the control assembly for the movable plate 206 for locking the first pipe 2 in the connected state and in the disconnected state. In a preferred embodiment, the locking mechanism comprises a detent plate 207, a detent pin 208 and a first resilient member 209, wherein the detent plate 207 is shown in fig. 8 with a fixed cover provided over both guide blocks such that the movable plate 206 is reciprocally movable between the fixed base plate 205 and the detent plate 207. Meanwhile, a guide groove is formed on the surface of the positioning plate 207, and one end of the positioning pin 208 is a free end, is bent and embedded in the guide groove and can move in the guide groove; correspondingly, the other end of the positioning pin 208 is a connecting end, which is movably (rotatably) connected to the movable plate 206, so that when the movable plate 206 moves correspondingly, the free end of the positioning pin 208 can slide correspondingly in the guiding slot.

Specifically, as shown in fig. 7, the guide groove on the positioning plate 207 includes a first guide groove 2071 and a second guide groove 2072 which are connected end to end and form a "heart-shaped" circulation channel, and then when the movable plate 206 moves close to the control tube 202 (the control tube 202 is unlocked), one end of the positioning pin 208 is movable in the second guide groove 2072 from its end facing away from the control tube 202 to its end facing close to the control tube 202; accordingly, when the movable plate 206 needs to move away from the control tube 202 (the control tube 202 is clamped by the two pipe clamping plates 211), one end of the positioning pin 208 can move in the first guide groove 2071 from its end close to the control tube 202 to its end away from the control tube 202.

In order to achieve stability of the free end movement of the positioning pin 208, steps having a certain height difference, namely, a first step 2073 and a second step 2074 are formed at the end connection positions of the two guide grooves. In practice, the first step 2073 is formed by the fact that the bottom of the end groove of the second guide groove 2072 is higher than the bottom of the end groove of the first guide groove 2071 (which can be understood as "the depth of the side end of the first guide groove 2071 is greater than the depth of the side end of the second guide groove 2072"), so that the end of the positioning pin 208 can go beyond the first step 2073 from the end of the second guide groove 2072 to the end of the first guide groove 2071 without moving back. Meanwhile, the second step 2074 is formed at a side of the positioning plate 207 facing away from the control tube 202 and is formed because the groove bottom height of the side of the first guide groove 2071 is higher than the groove bottom height of the second guide groove 2072, ensuring that the end of the positioning pin 208 moves only in the second guide groove 2072 and does not move from the end of the second guide groove 2072 into the first guide groove 2071 when the movable plate 206 moves close to the control tube 202, thereby ensuring the accuracy of the movement of the positioning pin 208.

Taking the view in fig. 7 as an example, by the above arrangement, the positioning pin 208 can be made to perform a cyclic motion in the "counterclockwise" direction on the positioning plate 207. Specifically, when the control tube 202 is switched from the open state to the open state, the movable plate 206 moves from the end facing away from the control tube 202 toward the control tube 202, and at this time, the free end of the positioning pin 208 moves in the second guide groove 2072, passes over the first step 2073, and then enters the end of the first guide groove 2071, and at this time, the control tube 202 is in the fully connected state; on the contrary, when the control pipe 202 needs to be switched from the open state to the open state (or the pipe flow is dynamically adjusted), the control movable plate 206 moves in the opposite direction, and at this time, the free end of the positioning pin 208 moves in the first guide groove 2071 until the free end passes over the second step 2074 and enters the end of the second guide groove 2072, thereby completing the open control of the control pipe 202.

However, it will be appreciated that the positions of the two guide grooves can be completely changed according to the actual setting requirements, and the positions of the two steps can be correspondingly changed, so that the positioning pin 208 can perform circular movement on the positioning plate 207 in a clockwise direction.

In addition, it can be seen that by the provision of the two guide grooves, a "heart-shaped" lock block 2075 can be formed on the positioning plate 207, the groove at one end of the lock block 2075 corresponding exactly to the formation position of the first step 2073, and the corner position at the other end corresponding to the formation position of the second step 2074. With the above arrangement, the free end of the positioning pin 208 can be restrained at the end of the first guide groove 2071, abutting in the groove at one end of the locking block 2075.

Further, a first elastic member 209 is disposed at one end of the movable plate 206 facing away from the pipe clamping plate 211, and one end of the first elastic member 209 is fixedly disposed, and the other end of the first elastic member is connected to the movable plate 206, so that when the movable plate 206 moves close to the control pipe 202, the elastic force of the first elastic member 209 needs to be overcome, and the first elastic member 209 is stretched. In this way, when the free end of the positioning pin 208 passes over the first step 2073 and reaches the end groove of the locking block 2075, the free end can be tensioned and abutted by the first elastic member 209, so as to ensure that the control assembly is locked in the state, and at this time, the clamping of the control tube 202 by the tube clamping plate 211 is released, and the first tube 2 is always in the communicating state. Accordingly, when the free end of the positioning pin 208 passes over the second step 2074 and enters the end of the second guide groove 2072, the control tube 202 is always held by the two tube clamping plates 211 and the first tube 2 is always disconnected by the first elastic member 209.

In a preferred embodiment, the first elastic member 209 is a tension spring, one end of which is connected to the inside of the housing 1, and the other end of which is connected to the end of the movable plate 206. Meanwhile, in a preferred embodiment, in order to realize the driving of the movable plate 206, a first trigger 210 is correspondingly provided, the middle part of which is hinged with the end part of the movable plate 206, and a section facing away from the trigger part is hinged inside the casing 1, so as to form a driving member in the form of a "lever". When the first trigger 210 is pulled, it rotates around the end, and at this time, the movable plate 206 is driven to move correspondingly.

Further, as shown in fig. 12 to 15, the second pipe 3 in the preferred embodiment is a suction pipe including a third connection pipe 301, an anti-blocking control member 302, and a fourth connection pipe 303 which are sequentially communicated. One end of the third connecting pipe 301 is connected with one end of the anti-blocking control member 302, and the other end of the third connecting pipe is communicated with the suction pipe cavity in the double-cavity pipe 4; accordingly, one end of the fourth connection pipe 303 is connected to one end of the anti-blocking control member 302, and the other end is connected to the second external connection pipe 6, through which the water generated during the operation and the washed water can be sucked away from the operation wound surface.

As shown in fig. 13, 15, the anti-blocking control member 302 in the preferred embodiment includes two lumens, a first lumen 3021 and a second lumen 3022, disposed side-by-side, preferably in parallel. One end of the first lumen 3021 is open and is connected to the third connection tube 301, and a through hole for communicating with the second lumen 3022 is formed in a side wall of the first lumen 3021, which is close to one end of the third connection tube 301, for allowing water to enter the second lumen 3022 from the first lumen 3021. Accordingly, the other end of the first lumen 3021 is preferably provided in a closed manner, that is, a space for accommodating the block-shaped residue is formed in the first lumen 3021, so as to realize deposition and storage of the block-shaped residue, and prevent the suction line from being blocked due to the existence of the block-shaped residue.

It will be appreciated that in a preferred embodiment, the end of the first lumen 3021 facing away from the third connecting tube 301 may be provided in the form of an openable and closable valve and be connected with a residue discharge tube at this end for the discharge of deposited residues.

Further, in the preferred embodiment, two ends of the second lumen 3022 are respectively in an open state, one end of the second lumen 3022 is connected to the end of the fourth connecting tube 303, and a piston 304 is disposed at the other end of the second lumen, and the piston 304 can reciprocate along the axial direction of the second lumen 3022 and can be embedded into the second lumen 3022 at the end, so that the second lumen 3022 is separated from a through hole on the side wall thereof, which is communicated with the first lumen 3021, and further on-off control of the anti-blocking control member 302 is achieved. It will be appreciated that the mating of the piston 304 with the second lumen 3022 is lower than the two lumen communication site, i.e., the two lumen communication site is located on the side of the second lumen 3022 that faces away from the fourth connection tube 303 where the piston 304 mates, as shown in fig. 13.

With the above arrangement, the following procedure can be realized. When the piston 304 is separated from the second lumen 3022, the two lumens are respectively communicated with the two connection pipes, at this time, the pumped water from the third connection pipe 301 may enter the first lumen 3021, the large residues in the pumped water may be deposited and stored at the bottom of the first lumen 3021, and the other water enters the second lumen 3022 through the through hole between the two lumens and is led out through the second lumen 3022, the fourth connection pipe 303 and the second external connection pipe 6. When the piston 304 is mated with the end of the second lumen 3022, the second lumen 3022 is closed and at this time the second conduit 3 is disconnected and no aspiration is performed.

In addition, as can be seen from fig. 15, the end of the piston 304 is matched with the end of the second pipe cavity 3022 in a sliding sealing manner, so that corresponding water can be prevented from overflowing from the anti-blocking control member 302 into the housing 1 when the second pipe 3 is communicated. Accordingly, the second lumen 3022 is provided with a stepped hole inside, a blocking opening having an inner diameter smaller than that of the end of the second lumen 3022 is formed, and the end of the piston 304 is provided with a blocking piece having an outer diameter smaller than that of the end of the second lumen 3022, so that when the piston 304 moves, the blocking piece can move synchronously, approach or separate from the blocking opening, and further the blocking or opening of the second lumen 3022 is completed.

Further, as shown in fig. 12 and 14, in the preferred embodiment, the driving of the piston 304 is achieved by the second trigger 306, one end of the second trigger 306 is rotatably connected to the inner side wall of the housing 1, and a strut is disposed at the end of the side, so that the strut is rotatably connected to one end of the piston 304 facing away from the second lumen 3022, so that a "lever" structure can be formed between the second trigger 306 and the piston 304, and the second trigger 306 can correspondingly rotate with the connection portion between the second trigger 306 and the housing 1 as a fulcrum, and at this time, the strut rotates with a step to drive the piston 304 to move.

In order to ensure an accurate movement of the piston 304, a guide block is provided on the inside of the housing 1, as shown in fig. 2, to ensure that the movement of the piston 304 is always in its axial direction. In addition, in order to achieve automatic resetting of the second trigger 306, a second elastic member 305 is provided on a side of the piston 304 facing away from the second lumen 3022, one end of which is fixed in the housing 1, and the other end of which abuts against an end of the piston 304. In turn, as the second trigger 306 is compressed and the piston 304 is moved away from the second lumen 3022, the second resilient member 305 is continually compressed, such that when the user releases the second trigger 306, the second resilient member 305 can push the piston 304 toward the second lumen 3022 under its post-compression restoring force, causing the second trigger 306 to return.

In a preferred embodiment, the second elastic member 305 is a compression spring, which is coaxially disposed with the piston 304, and a guide rod is disposed at an end of the piston 304, such that one end of the compression spring is sleeved on the guide rod; correspondingly, a limiting groove is formed in the shell 1 corresponding to the other end of the pressure spring, so that the other end of the pressure spring is embedded into the limiting groove and is in abutting limiting with the bottom of the limiting groove, as shown in fig. 2.

With the above arrangement, it can be seen that when the second trigger 306 is pressed against the pistol grip, the compression spring is compressed and the piston 304 is brought out of the locked position of the second lumen 3022, where the two lumens are in communication, and the second conduit 3 is in communication. When the user releases the grip of the second trigger 306, the piston 304 may match the locked position of the second lumen 3022 under the restoring force of the compression spring, and the second trigger 306 is driven back to the initial position.

In connection with the foregoing, it will be readily appreciated that for the preferred embodiment of the handle gun, the first trigger 210 and the second trigger 306 are on the same side of the handle gun "stock" and the first trigger 210 is above the second trigger 306 (i.e., on the side of the second trigger 306 facing away from the bottom of the stock), this arrangement is a result of sufficient ergonomic integration. Through the arrangement, when a user holds the handle gun, the index finger of the user can be buckled on the first trigger 210, and the middle finger, the ring finger and the little finger can be buckled on the second trigger 306; accordingly, the thumb and palm of the user can stably hold the pistol grip of the pistol. Meanwhile, when the first trigger 210 and the second trigger 306 are controlled, the movement range of the fingers of the user is extremely small, so that the energy consumption of the user can be effectively saved, and the distraction of a doctor due to the use of a handle gun in the operation process is avoided. And secondly, through the corresponding arrangement of the two elastic pieces, the handle gun can be automatically kept in a locking state when not in work, so that manual locking of a doctor during operation is avoided, the control links of the handle gun are reduced, and convenience is provided for the use of the doctor during operation. In addition, through the corresponding setting of positioning mechanism, can make the doctor lock at the state of washing when using, avoid appearing producing because of long-time finger tingling, the discomfortableness situation such as souring of pressing first trigger 210, reduce the loss to user's physical power.
