Example (b):

to the handle rifle of the preferred embodiment of the utility model, it mainly uses in doctor's operation process for carry out water liquid to the operation surface of a wound and wash and/or water liquid suction, and it includes the casing 1 that is "pistol" form, and the person of facilitating the use holds and controls the use with one hand. Meanwhile, an accommodating chamber is formed in the housing 1, and at least one pipeline is arranged in the accommodating chamber and used for conveying water liquid. It is understood that the "water liquid transportation" may be the pumping of water liquid from the operation area, or the transportation of external water liquid to the operation area, which may be preferable according to the actual situation.

In a preferred embodiment, the pipe in the housing 1 comprises a suction pipe for sucking and discharging water in the operation area, and the handle gun at least has a suction function and can be called as a suction handle gun. Of course, when there is only one pipe, the pipe can also satisfy other functional requirements, for example, the pipe can be a "flushing pipe" to satisfy the flushing requirement.

In another embodiment, the housing 1 has at least two pipelines, each of which is independent of the other and can perform corresponding operations and uses. Moreover, it is understood that, when the plurality of pipelines are provided, the functions of the plurality of pipelines may be the same or different, for example, two suction pipelines are provided at the same time to meet suction requirements under different conditions, or a suction pipeline and a flushing pipeline are provided at the same time to respectively fulfill suction requirements and flushing requirements, which may be preferred according to actual needs, and are not described herein.

In the preferred embodiment as shown in fig. 1 to 15, two pipes, i.e., a first pipe 2 and a second pipe 3, are provided in the housing 1, and will be described in detail later by way of example.

In particular, the housing 1 of the preferred embodiment comprises a first shell 101 and a second shell 102, both preferably made of medical grade plastic material, safe and harmless and having a low weight, ensuring a long-term grip by the user without significant hand fatigue. It is understood that the two housings are respectively formed with a containing cavity, and the two housings are spliced to form a complete cavity for containing the two pipelines, and the two pipelines are isolated from the external environment of the housing 1.

Meanwhile, a double-cavity tube 4 is preferably arranged at the gun mouth part of the shell 1 and is used for being correspondingly communicated with one end of the two pipelines, so that when the handle gun is actually used, the end part of the double-cavity tube 4 directly acts on a working area (namely, an intraoperative part needing flushing and suction); correspondingly, the bottom of the 'grab handle' of the shell 1 is correspondingly provided with an external pipeline which is used for being communicated with the other ends of the two pipelines, so that the pumping of the flushing liquid and the suction of the suction 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 securing the double lumen tube 4 in two-line communication at the "muzzle" position of the housing 1, ensuring reliable placement of the double lumen tube 4. Of course, it will be appreciated that locking of the ends of the first and second housings 101, 102 may also be accomplished by providing a dual lumen threaded cap 103 such that the two housings secure the ends of the dual lumen tube 4.

In the case of the double lumen tube 4 in the exemplary embodiment, two separate lumens are formed therein for carrying out the respective fluid conducting processes. In a preferred embodiment, the two lumens of the double-lumen tube 4 are a flushing lumen and a suction lumen respectively, and the conveying process of the flushing water liquid of the operation mouth and the suction process of the flushing water liquid, the tissue liquid in the operation and the like are independently completed.

Further, as for the first pipeline 2 in the preferred embodiment, it is preferably a flushing pipeline, and includes a first connecting pipe 201, a control pipe 202 and a second connecting pipe 203 which are communicated in sequence. 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 lumen in the double-lumen pipe 4; correspondingly, 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 liquid for irrigation is introduced to the wound surface in the 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 assembly is arranged in the housing 1 corresponding to the control pipe 202.

More specifically, the control assembly in the preferred embodiment is shown in fig. 8 to 11, and includes a fixed base plate 205, a movable plate 206, and a line clamp plate 211 disposed in pair on the side of the movable plate 206 adjacent to the control tube 202. In order to achieve the displacement guiding and limiting of the movable plate 206, guide blocks are provided in pairs on the fixed base plate 205, as shown in fig. 2, so that the movable plate 206 can be just inserted between the two guide blocks and perform reciprocating displacement therebetween, and further approach or depart from the control pipe 202 provided at one side of the end of the movable plate 206. In the preferred embodiment, the opposing side wall surfaces of the guide blocks are arranged in parallel, with the spacing between them being just equal to the width of the movable plate 206. Meanwhile, the inner sides of the end parts of the two guide blocks close to the control tube 202 are respectively provided with a wedge-shaped structure, the two wedge-shaped structures are symmetrically arranged, and the end parts of the two guide blocks form a horn mouth shape. In addition, the pipe clamp 211 is hinged at one end thereof to an end of the movable plate 206 and is rotatable relative to the end.

Accordingly, in order to cooperate with the two pipe clamps 211, the control pipe 202 in the preferred embodiment is bent in an arc or ring-shaped configuration, such as the ring-shaped configuration shown in fig. 9, and its end portion communicating with the two connection pipes is locked to the end portion of the fixed base plate 205 by a locking piece, as shown in fig. 8 to 11. At this time, the two line clamps 211 are provided on both outer circumferential sides of the ring-shaped control pipe 202.

It can be understood that when the connecting portion of the pipe clamp 211 is opposite to the corresponding wedge surface, the two pipe clamps 211 can rotate to the position of being attached to the corresponding wedge surface, and at this time, the opening angle between the two pipe clamps 211 is the largest, and the control pipe 202 can be opened to form an annular structure. When the movable plate 206 moves away from the control tube 202 between the guide blocks, the tube clamps 211 are pulled into between the guide blocks. At this time, the two pipe clamps 211 are switched from the "open state" to the "closed state", the space between the two is greatly reduced, one end of the annular control tube 202 is clamped by the two pipe clamps 211, the "annular" is switched to the "flat shape", the middle part of the control tube 202 is pressed and bent, and the communication of the control tube 202 is blocked.

Of course, it can also be understood that, when the movable plate 206 moves close to the control tube 202, the hinged end portions of the two tube clamps 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 tube clamps 211 becomes larger, and if a certain amount of hydraulic liquid is introduced into the first tube 2 at this time, the control tube 202 can be restored to be annular, so as to achieve the communication of the first tube 2.

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

Obviously, it can also be understood that, through the arrangement of the control assembly, not only the on-off control of the first pipeline 2 can be realized, but also the flow rate and the water pressure in the first pipeline 2 can be correspondingly adjusted. Because the motion of fly leaf 206, can adjust the angle that presss from both sides between two pipeline splint 211 in succession for it can be adjusted in succession to the centre gripping angle of control tube 202, so, can correspond centre gripping control tube 202 and produce deformation in its ring line middle part, and then the flow size in the adjustment first pipeline 2 and the water pressure size of washing satisfy different user demands.

Further, a locking mechanism is provided in the control assembly for the movable plate 206 for locking the communication state and the disconnection state of the first pipeline 2. In a preferred embodiment, the locking mechanism includes a positioning plate 207, a positioning pin 208 and a first elastic member 209, wherein the positioning plate 207 is provided with a fixed cover on two guide blocks as shown in fig. 8 such that the movable plate 206 can reciprocate between the fixed base plate 205 and the positioning plate 207. Meanwhile, a guide groove is formed in 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; accordingly, the other end of the positioning pin 208 is a connecting end, which is movably connected (rotatably connected) to the movable plate 206, so that the free end of the positioning pin 208 can slide in the guiding groove when the movable plate 206 moves correspondingly.

Specifically, the guide grooves of the positioning plate 207 are shown in fig. 7, and include a first guide groove 2071 and a second guide groove 2072 which are connected end to end and form a "heart-shaped" circular groove, and then when the movable plate 206 is moved 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 away from the control tube 202 to its end 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 tube clamps 211), one end of the positioning pin 208 can move in the first guide slot 2071 from the end close to the control tube 202 to the end away from the control tube 202.

In order to achieve stability of the movement of the free end of the dowel pin 208, steps having a certain height difference, i.e., 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 end bottom height of the second slot 2072 being higher than the end bottom height of the first slot 2071 (which can also be understood as "the side end of the first slot 2071 is excavated deeper than the side end of the second slot 2072"), so that the end of the pin 208 can only pass through the first step 2073 from the end of the second slot 2072 to the end of the first slot 2071 without performing a displacement movement in reverse. Meanwhile, the second step 2074 is formed at the side of the positioning plate 207 facing away from the control pipe 202 and is formed because the height of the bottom of the first guide groove 2071 at the side is higher than that of the second guide groove 2072, so that it is ensured 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 pipe 202, thereby ensuring the accuracy of the movement of the positioning pin 208.

Taking the view angle in fig. 7 as an example, the positioning pin 208 can be made to perform a cyclic motion in a "counterclockwise" direction on the positioning plate 207 by the above arrangement. Specifically, when the control tube 202 is switched from the disconnected state to the open state, the movable plate 206 moves from the end away from the control tube 202 to close to the control tube 202, and the free end of the positioning pin 208 moves in the second slot 2072, passes over the first step 2073 and enters the end of the first slot 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 dynamically adjust the flow rate of the pipeline), the control flap 206 moves in the reverse direction, and the free end of the positioning pin 208 moves in the first guide slot 2071 until the free end of the positioning pin passes through the second step 2074 and enters the end of the second guide slot 2072, thereby completing the open control of the control pipe 202.

However, it is understood that the positions of the two guide slots can be completely exchanged according to the actual setting requirement, and the positions of the two steps can be correspondingly exchanged, so that the positioning pin 208 can perform a cyclic movement on the positioning plate 207 in a "clockwise" direction.

In addition, it can be seen that, by the arrangement of the two guide grooves, a "heart-shaped" locking block 2075 can be formed on the positioning plate 207, the groove of one end of the locking block 2075 exactly corresponds to the formation position of the first step 2073, and the corner position of the other end corresponds 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 slot 2071, abutting in the groove at one end of the locking block 2075.

Further, a first elastic member 209 is disposed at an end of the movable plate 206 opposite to the pipe clamp 211, one end of the first elastic member 209 is fixedly disposed, and the other end of the first elastic member 209 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 needs to be 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 first elastic member 209 can be pulled tightly to ensure that the control assembly is locked in this state, and at this time, the pipe clamp plate 211 releases the clamping of the control pipe 202, and the first pipe 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 free end can be always in this state by the first elastic member 209, and at this time, the control pipe 202 is clamped by the two pipe clamping plates 211, and the first pipe 2 is always in the disconnected state.

In a preferred embodiment, the second elastic member 305 is a compression spring, which is disposed coaxially with the piston 304, and a guide rod is disposed at an end of the piston 304, such that an end of the compression spring is sleeved on the guide rod; correspondingly, a limiting groove is formed in the housing 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 abutted and limited by 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 towards the pistol grip, the compression spring is compressed, the piston 304 is brought out of the locking position of the second lumen 3022, the two lumens are correspondingly connected, and the second conduit 3 is in a connected state. When the user releases the grip of the second trigger 306, the piston 304 may be matched to the locked position of the second lumen 3022 by the restoring force of the compression spring, and the second trigger 306 is driven back to the initial position.
