Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a laparoscopic suction device that can grasp foreign objects. Background Technology

[0002] It is known that during laparoscopic surgery, there are often situations where the anatomy is unclear or there is a lot of bleeding from the wound. It is necessary to use a suction device to help expose important target channels and tissues. If it is necessary to remove fluid, blood or other fluids in the surgical area, a laparoscopic suction device with a cylindrical hollow tube is commonly used for suction operation. If there are blood clots or foreign tissues in the surgery, a suction device is needed to remove the blood clots or foreign tissues.

[0003] However, in actual use, the suction device uses a cylindrical hollow tube, which is easy to clog, causing medical staff to repeatedly flush the lumen, wasting manpower and energy. For blood clots or foreign body tissue, the suction device often clogs due to the blood clot being too thick or coagulating into clumps, or the foreign body being too large, which in turn leads to a decrease in suction efficiency. Therefore, a laparoscopic suction device that can grab foreign bodies is proposed as a further improvement. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a laparoscopic suction device that can grasp foreign objects, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laparoscopic suction device capable of grasping foreign objects, the suction device comprising: a suction tube, a telescopic sleeve, a flushing operation handle, a grasping operation handle, and a suction switch valve;

[0006] The telescopic sleeve is fixedly installed on the inner wall of the suction tube. One end of the flushing operation handle and one end of the gripping operation handle are both fixedly installed on the outer surface of one end of the suction tube. The other end of the suction tube is provided with a gripping device. A gripping control mechanism is provided between the gripping device and the gripping operation handle.

[0007] A flushing tube connector is fixedly installed on the surface of the suction tube near the flushing operation handle, and a flushing control mechanism is provided between the flushing tube connector and the flushing operation handle.

[0008] The suction switch valve is fixedly installed at the end of the suction tube away from the gripping device.

[0009] Furthermore, the gripping control mechanism includes: a telescopic rod and a telescopic groove;

[0010] The telescopic rod slides inside the telescopic sleeve. The telescopic groove is formed on the telescopic sleeve and the suction tube near the gripping operation handle. One end of the telescopic rod is fixedly connected to the gripping device, and the other end of the telescopic rod is fixedly connected to the gripping operation handle.

[0011] Furthermore, the flushing control mechanism includes: a telescopic plate and a flushing through hole;

[0012] All flushing tube connectors are internally connected to the suction tube. The flushing tube connectors have a sealing groove on the side wall near the suction tube. The flushing through hole is opened on the telescopic plate. The telescopic plate is tightly attached to the outer surface of the suction tube. One end of the telescopic plate is fixedly connected to the flushing operation handle, and the other end of the telescopic plate is inserted into the sealing groove.

[0013] A stop block is fixedly installed on the outer surface of the suction tube, and the stop block contacts the end of the telescopic plate that passes through the sealing groove.

[0014] Furthermore, the gripping device is configured as a flexible clamp structure that unfolds into a claw shape.

[0015] Furthermore, the gripping device is configured as a flexible mesh basket structure that unfolds into a grid.

[0016] Furthermore, the gripping device is at least 10mm wide when unfolded; the outer diameter of the suction tube is set in the range of 5-8mm; and the inner diameter of the suction tube is set in the range of 4-7mm.

[0017] Furthermore, both the flushing operation handle and the gripping operation handle are made of an elastic, repositionable material;

[0018] The shape of the rinsing operation handle is the same as the shape of the gripping operation handle.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] Compared with existing technologies, the suction device designed in this utility model has the functions of suction, foreign body retrieval, and rinsing. It completes three operational tasks through a single lumen, namely the suction tube: it can aspirate liquid, remove foreign bodies or blood clots, and rinse the surgical area. When aspirating liquid is the primary function, it is similar to the rapid suction of ordinary suction devices. By opening the suction switch valve, the suction tube can be used for rapid suction. When the blood clot is viscous, the grabbing control mechanism is used to push the grabbing device out of the suction tube. After the grabbing device covers the blood clot or foreign body, the foreign body is pulled out of the body along with the suction device designed in this utility model, avoiding repeated rinsing of the lumen of the suction tube. If the surgical area is blurry, the rinsing control mechanism can be used to control the connection between the rinsing tube connector and the suction tube, thereby controlling the entry of rinsing water and completing the rinsing of the surgical area during laparoscopic surgery to maintain a clear field of vision.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] As attached Figure 1-5 The laparoscopic suction device shown is capable of grasping foreign objects. The suction device includes: a suction tube 1, a telescopic sleeve 2, a flushing operation handle 3, a grasping operation handle 4, and a suction switch valve 5.

[0034] The telescopic sleeve 2 is fixedly installed on the inner wall of the suction tube 1. One end of the flushing operation handle 3 and one end of the gripping operation handle 4 are both fixedly installed on the outer surface of one end of the suction tube 1. The other end of the suction tube 1 is provided with a gripping device 6. A gripping control mechanism 7 is provided between the gripping device 6 and the gripping operation handle 4.

[0035] A flushing pipe connector 8 is fixedly installed on the surface of the suction pipe 1 near the flushing operation handle 3, and a flushing control mechanism 9 is provided between the flushing pipe connector 8 and the flushing operation handle 3.

[0036] The suction switch valve 5 is fixedly installed at the end of the suction pipe 1 away from the gripping device 6.

[0037] The suction device designed in this utility model is similar to the rapid suction of a common suction device. The suction switch valve 5 is opened, and rapid suction is performed through the suction tube 1.

[0038] The gripping device 6 is controlled by the gripping control mechanism 7: when the gripping device 6 is pushed out and unfolded from the suction tube 1, it is convenient to grip the foreign object; when the gripping device 6 is retracted, the gripping device 6 is squeezed and constrained by the suction tube 1, and the gripped foreign object is firmly gripped, and finally the foreign object is pulled out of the body along with the whole device.

[0039] The flushing control mechanism 9 controls whether the flushing pipe connector 8 and the suction pipe 1 are connected. When the suction switch valve 5 is closed and the flushing pipe connector 8 and the suction pipe 1 are connected, the flushing water flows along the suction pipe 1 to achieve the flushing function. If the flushing pipe connector 8 and the suction pipe 1 are not connected, the flushing function is turned off.

[0040] Therefore, in summary, the suction device designed in this utility model has the functions of suctioning liquid, rinsing, and removing foreign objects; it completes three operational tasks through a single lumen, namely the suction tube 1: it can suction liquid via the suction switch valve 5, remove foreign objects or blood clots via the grasping control mechanism 7, and introduce clean water for rinsing via the rinsing control mechanism 9, thereby rinsing the surgical area during laparoscopic surgery and maintaining a clear field of vision.

[0041] Among them, the suction switch valve 5 can be a ball valve, and its valve switch is close to the flushing operation handle 3 and the gripping operation handle 4. Therefore, the user can operate the flushing operation handle 3, the gripping operation handle 4 and the suction switch valve 5 with one hand, so that the corresponding functions can be controlled more conveniently.

[0042] In a preferred embodiment, as shown in the appendix Figure 1-5 As shown, the gripping control mechanism 7 includes: a telescopic rod 71 and a telescopic groove 72;

[0043] The telescopic rod 71 slides inside the telescopic sleeve 2. The telescopic groove 72 is opened on the telescopic sleeve 2 and the suction tube 1 near the gripping operation handle 4. One end of the telescopic rod 71 is fixedly connected to the gripping device 6, and the other end of the telescopic rod 71 is fixedly connected to the gripping operation handle 4.

[0044] In this process, the operator controls the gripping handle 4 to drive the telescopic rod 71 to slide inside the telescopic sleeve 2. When the telescopic rod 71 drives the gripping device 6 to be pushed out and unfolded from the suction tube 1, the gripping device 6 can grip the foreign object. Then, when the telescopic rod 71 drives the gripping device 6 to move towards the suction tube 1, the gripping device 6 is squeezed and constrained by the suction tube 1, and firmly grips the gripped foreign object, thereby achieving the gripping effect.

[0045] In a preferred embodiment, as shown in the appendix Figure 1-5 As shown, the flushing control mechanism 9 includes: a telescopic plate 91 and a flushing through hole 92;

[0046] All flushing pipe connectors 8 are connected to the interior of suction pipe 1. A sealing groove 81 is provided on the side wall of flushing pipe connector 8 near suction pipe 1. A flushing through hole 92 is provided on telescopic plate 91. Telescopic plate 91 is in close contact with the outer surface of suction pipe 1. One end of telescopic plate 91 is fixedly connected to flushing operation handle 3. The other end of telescopic plate 91 is inserted into sealing groove 81.

[0047] The operator controls the flushing handle 3 to move the telescopic plate 91 within the sealing groove 81.

[0048] When the flushing through hole 92 enters the flushing pipe connector 8, the water flow in the flushing pipe connector 8 will enter the suction pipe 1 through the flushing through hole 92. At this time, the suction switch valve 5 is in the closed state. The clean water entering the suction pipe 1 will reach the designated area along the pipe wall of the suction pipe 1 to remove the covering. The surgical area is flushed during laparoscopic surgery to maintain a clear field of vision.

[0049] When the flushing through hole 92 is removed from the flushing pipe connector 8, the water flow in the flushing pipe connector 8 will be blocked by the telescopic plate 91, thus stopping the flushing.

[0050] The telescopic plate 91 has a sealing ring between it and the flushing pipe connector 8 to improve the sealing effect and prevent water from leaking out between the flushing pipe connector 8 and the flushing pipe connector 8, thus improving the flushing effect.

[0051] A stop 93 is fixedly installed on the outer surface of the suction tube 1, and the stop 93 contacts the end of the telescopic plate 91 that passes through the sealing groove 81.

[0052] The function of the stop block 93 is to position it. When the stop block 93 contacts the telescopic plate 91, it ensures that the flushing through hole 92 is located inside the flushing pipe connector 8.

[0053] In a preferred embodiment, as shown in the appendix Figure 4As shown, the gripping device 6 is configured to elastically unfold into a claw-shaped clamp structure so that the telescopic rod 71 can drive the gripping device 6: if it extends from the suction tube 1, the gripping device 6 unfolds to form a clamp; if it retracts the suction tube 1, the gripping device 6 clamps the foreign object.

[0054] In a preferred embodiment, as shown in the appendix Figure 5 As shown, the gripping device 6 is configured to elastically unfold into a mesh basket structure so that the telescopic rod 71 can drive the gripping device 6: if it extends from the suction tube 1, the gripping device 6 unfolds to form a basket to trap the foreign object; if the suction tube 1 is retracted, the gripping device 6 retracts to trap the foreign object.

[0055] In a preferred embodiment, as shown in the appendix Figure 1-5 As shown, the gripping device 6 is at least 10mm wide when unfolded; the outer diameter of the suction tube 1 is set in the range of 5-8mm; and the inner diameter of the suction tube 1 is set in the range of 4-7mm.

[0056] In one embodiment, the gripping device 6 is 20mm wide when unfolded to grip foreign objects such as stones and blood clots; the wall thickness of the suction tube 1 can be set to 1mm.

[0057] In a preferred embodiment, as shown in the appendix Figure 1-5 As shown, both the flushing operation handle 3 and the sleeve gripping operation handle 4 are made of elastic, resettable material. When the flushing operation handle 3 and the sleeve gripping operation handle 4 are not operated, the flushing operation handle 3 drives the telescopic plate 91 to block the flushing pipe connector 8, and the sleeve gripping operation handle 4 drives the telescopic rod 71 to retract the sleeve gripping device 6 back into the suction pipe 1. When the flushing operation handle 3 and the sleeve gripping operation handle 4 are operated, the flushing operation handle 3 drives the telescopic plate 91 to open the flushing pipe connector 8, and the sleeve gripping operation handle 4 drives the telescopic rod 71 to push the sleeve gripping device 6 out of the suction pipe 1 and unfold it.

[0058] The shape of the rinsing operation handle 3 is the same as the shape of the gripping operation handle 4; so that it is easy to grip during operation.

[0059] Working principle of this utility model:

[0060] When the main function is to aspirate liquid, the operator opens the aspiration switch valve 5 with one hand and quickly aspirates through the aspiration tube 1; while the flushing operation handle 3 and the sleeve grab operation handle 4 are in the initial state, that is, the telescopic plate 91 blocks the flushing tube connector 8, and the sleeve grab device 6 retracts into the aspiration tube 1 without affecting the aspiration.

[0061] When a blood clot is viscous and needs to be grasped, the operator operates the grasping handle 4 with one hand, and pushes the grasping device 6 out of the suction tube 1 through the telescopic rod 71. The grasping device 6 is used to wrap the blood clot or foreign object. Then, the repositioned grasping handle 4 moves the grasping device 6 towards the suction tube 1 through the telescopic rod 71. The grasping device 6 is squeezed and constrained by the suction tube 1, firmly grasping the foreign object. Finally, the foreign object is pulled out of the body along with the suction device designed in this utility model.

[0062] When the flushing function is required, the suction switch valve 5 must be closed. The operator controls the flushing operation handle 3 with one hand to move the telescopic plate 91 within the sealing groove 81. If the flushing through hole 92 on the telescopic plate 91 enters the flushing pipe connector 8, the water flow in the flushing pipe connector 8 will enter the suction pipe 1 through the flushing through hole 92. The clean water entering the suction pipe 1 will reach the designated area along the pipe wall of the suction pipe 1 to remove the covering material. In laparoscopic surgery, the surgical area is flushed to maintain a clear field of vision. If the flushing through hole 92 of the telescopic plate 91 moves out of the flushing pipe connector 8, the water flow in the flushing pipe connector 8 will be blocked by the telescopic plate 91, thus stopping the flushing.

[0063] If rinsing and grabbing foreign objects are required, the suction switch valve 5 must be closed, and the operator can operate the rinsing control handle 3 and the grabbing control handle 4 with one hand.

[0064] If it is necessary to attract and grab foreign objects, the attraction switch valve 5 should be in the open state, and the operator should operate the control sleeve grab handle 4 with one hand.
