Description

Technical Field

[0001] The invention relates to a medical device, in particular to a graspable suction device for a thoracoscope. Background Art

[0002] In modern medical practice, single-port thoracoscopic surgery has become a common minimally invasive surgical technique and is widely used in the treatment of chest diseases. The advantages of this single-port operation are that it reduces surgical trauma, relieves the patient's pain, and helps to recover faster. During surgery, an aspirator is used to remove smoke and liquid from the surgical area. The application of traditional aspirators in single-port operations is subject to some limitations because they may affect the entry of other instruments, interfere with the field of vision, or cause inconvenience during surgery. When clearing lymph nodes, doctors often need to use additional grasping tools to fix the lymph nodes, while the aspirator requires another doctor or assistant to operate. This division of labor operation mode not only increases the difficulty of coordination between surgical personnel, but also may prolong the operation time. Therefore, in order to improve the convenience and efficiency of surgery, the present invention provides a graspable aspirator for thoracoscopic surgery. Summary of the invention

To achieve the above purpose, the technical solution adopted by the present invention is: a graspable suction device for thoracoscopic use, including a suction tube body and a connecting piece, the connecting piece includes a suction device joint and a graspable suction device connector. The graspable suction device connector has a built-in hollow connecting tube, a spring and a grasping forceps.

[0004] The tail end of the suction tube body is provided with a liquid discharge tube, a pressing device is provided inside the handle, and the outside is a polygonal prism. The front end of the suction tube body is connected in a spiral manner and can be connected to a connecting piece.

[0005] The pressing device comprises a liquid discharge pipe, a first rotating frame and a second rotating frame, and the liquid discharge pipe is a pressing button, which rotates and connects the first connecting block and the second connecting block when pressed, and the inside of the liquid discharge pipe, the first rotating frame and the second rotating frame are hollow.

[0006] The front end of the grippable suction device connector is a sleeve, a spring and a hollow connecting tube are arranged inside the sleeve, and the spring is sleeved outside the hollow connecting tube. The front end of the hollow connecting tube is provided with a suction hole and connected to the grasping forceps, and the rear end is connected to the built-in pressing device, and the diameter of the hollow connecting tube is smaller than the diameter of the suction tube body.

[0007] The outer peripheral surface of the suction device connector is provided with evenly arranged longitudinal grooves and suction holes. The suction device connector forms an angle with the suction device body, and suction device connectors with different angles can be equipped for doctors to choose. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] See also Figure 1 The present invention provides a graspable suction device for thoracoscopic use, comprising a suction tube body 11, a built-in pressing device 12, a suction device connector 13, and a graspable suction device connector 14.

[0015] See also Figure 2 The tail end of the suction tube body 11 is a discharge tube 21 for connecting a negative pressure aspirator. The inside of the handle 22 is a built-in pressing device 12, and the outside is a polygonal prism to increase friction and hand-holding comfort. The front end of the suction tube 23 is an inner wire spiral 24, which is connected to the connecting piece.

[0016] See also Figure 3 The built-in pressing device 12 includes a liquid discharge pipe 21, a first rotating frame 32, and a second rotating frame 33. The centers of the liquid discharge pipe 21, the first rotating frame 32, and the second rotating frame 33 are hollow to form a suction channel. The first rotating frame 32 and the second rotating frame 33 both have staggered grooves. By pressing the liquid discharge pipe 21, the grooves of the first rotating frame 32 and the second rotating frame 33 are engaged or separated.

[0017] See also Figure 4The suction device connector 13 is an outer thread spiral 41, which is connected to the inner thread spiral 24 of the front section of the suction tube body 11. The outer peripheral surface of the front section 43 of the suction device connector 13 has evenly arranged longitudinal grooves to increase friction, so that it is not easy to slip when pulling or pushing and pulling tissues, and is provided with suction holes for sucking smoke or effusion or blood.

[0018] The suction device joint 13 can be designed with different curvatures 42 for doctors to choose, which is convenient for operation. When the curvature reaches 90 degrees, it can be used as a baffle.

[0019] See also Figure 5 , which is a graspable suction device connector 14. The outermost sleeve 52 is an internal thread spiral, which is connected to the internal thread spiral 24 at the front end of the suction tube 23. The hollow connecting tube 51 is inserted into the suction tube 23 and connected to the second rotating frame 33 of the built-in pressing device 12. The front section of the hollow connecting tube 51 is slightly thinner and is connected to the spring 53. The front section 54 is provided with a suction hole for sucking smoke or effusion, blood accumulation, and is connected to the grasping forceps 55. When the drainage tube 21 is pressed, the first rotating frame 32 is pushed to rotate and engage with the second rotating frame 33, pushing the hollow connecting tube 51 to compress the spring 53, pushing the grasping forceps 55 out of the sleeve 52, and the grasping forceps 55 are naturally opened; when the drainage tube 21 is released, the first rotating frame 32 rotates and separates from the second rotating frame 33. Under the action of the retraction of the spring 53, the grasping forceps 55 retract into the sleeve 52. Due to the restriction of the sleeve 52, the grasping forceps 55 are closed, thereby grasping the lymph node or tissue. The inner side of the grasping forceps 55 is provided with a longitudinal groove to increase the grasping force.

[0020] In one embodiment of the present invention, the suction tube body 11 is connected to the suction device joint 13 and is used as a traditional suction device. Smoke, accumulated fluid or accumulated blood is sucked through the suction hole 43 and discharged through the suction tube 23, the first rotating frame 32, the second rotating frame 33 and the drainage pipe 21.

[0021] In another embodiment of the present invention, the suction tube body 11 is connected to the grippable suction device joint 14. When the drainage tube 21 is pressed, the first rotating frame 32 is pushed to rotate and engage with the second rotating frame 33, and the hollow connecting tube 51 is pushed to compress the spring 53, and the grasping forceps 55 are pushed out of the sleeve 52, and the grasping forceps 55 are naturally opened; when the drainage tube 21 is released, the first rotating frame 32 rotates and separates from the second rotating frame 33. Under the action of the retraction of the spring 53, the grasping forceps 55 retract into the sleeve 52, and the grasping forceps 55 are closed due to the restriction of the sleeve 52, so as to grasp the lymph node or tissue. Smoke, effusion or blood is sucked through the suction hole 54 and discharged through the hollow connecting tube 51, the first rotating frame 32, the second rotating frame 33, and the drainage tube 21.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
