Description

Technical Field

[0001] This invention relates to the field of suction cutting pliers technology, specifically disposable universal suction cutting pliers. Background Technology

[0002] Suction cutter forceps are a surgical instrument that integrates multiple functions such as suction, cutting, and clamping. It uses negative pressure to suction soft tissue and cuts it with a blade. The cut tissue is then suctioned out through a tube. This versatility allows suction cutter forceps to simplify the types of surgical instruments used in surgery and save doctors' operation time.

[0003] A suction-cutting forceps generally consists of three parts: a handle, a connecting tube, and a suction-cutting head. The handle is for the doctor to hold and operate, the connecting tube connects the handle and the suction-cutting head, and the suction-cutting head is responsible for suctioning and cutting tissue. In some new types of suction-cutting forceps, such as end-face cutting forceps, the suction-cutting tube opening and the cutting blade assembly are set on the suction-cutting end of the forceps tube, so that the suction-cutting forceps can perform suction-cutting operations on the end face of the forceps tube opening, thus solving the problem that traditional suction-cutting forceps can only perform suction-cutting operations on the side of the forceps tube.

[0004] However, current suction and cutting forceps have the following problems: they can be reused multiple times, which can easily lead to contamination. Disposable universal suction and cutting forceps need to reduce costs to reduce the treatment burden on patients. At the same time, current suction and cutting forceps cannot be universally adjusted, which makes it difficult to extract tissues. In recent years, the concept of minimally invasive surgery has gained popularity. With the qualitative leap in endoscopic imaging hardware, endoscopic minimally invasive technology has developed rapidly. However, the development of minimally invasive operating instruments is relatively lacking. In order to meet the clinical needs for the resection of organs, tissues, deep cavities and channels under endoscopy, especially for lesions under non-direct vision, we have developed this instrument. Summary of the Invention

[0005] The purpose of this invention is to provide a disposable universal suction and cutting pliers to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a disposable universal suction and cutting pliers, comprising a suction tube, a Luer connector, a connecting tube, a mating groove, a limiting end frame, a handle, and a trigger. The side end of the suction tube is connected to a Luer connector, which is connected to the connecting tube through a tube body. The connecting tube is located at the upper end of the handle and is connected to an external suction and discharge mechanism. The handle is equipped with a trigger, and the trigger and the handle are movably configured. By pressing the trigger, the position of the suction head rod is changed, allowing the suction head rod to be stretched and adjusted. A ball head is fixedly provided at the end of the suction head rod away from the trigger.

[0007] The rear end of the suction head rod is connected to the limiting end frame, and the limiting end frame is provided with a mating groove, through which the suction head rod can be adjusted.

[0008] Specifically, the straw and the bulb are connected in a movable manner. When the straw and the bulb are separated, the straw is connected to the tissue through a Luer connector and a connecting tube, which can remove bleeding and other liquid contaminants.

[0009] Specifically, the suction head rod is adjusted by pressing the trigger to change the position of the ball head, and when the ball head contacts the suction tube, it performs tissue biting and removal.

[0010] Specifically, the ball head is spherically shaped to perform omnidirectional cutting.

[0011] Specifically, the mating groove on the limiting end frame is used to limit the suction head rod, so that the suction head rod can be adjusted and moved along the mating groove.

[0012] Specifically, the rear end length of the suction head rod exceeds the mating groove distance by 10cm.

[0013] Specifically, the trigger has a spring telescopic rod at its rear end, and the trigger is telescopically connected via the spring telescopic rod. The bottom of the spring telescopic rod is fixed to the handle, and a cooperating rod is fixedly provided at the upper end of the trigger. A sleeve is fixedly connected to the cooperating rod, and a suction head rod is rotatably sleeved on the sleeve. The suction head rod and the sleeve can rotate relative to each other, and the sleeve can drive the suction head rod to move laterally.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The surgical field under endoscopy is characterized by its deep location and narrow, crowded space. Due to specific limitations, it is extremely difficult to simultaneously perform procedures such as cleaning the surgical field, exposing lesions, and separating and resecting them.

[0016] 1. This device has controllable continuous suction to promptly remove surgical cavity smoke and dust, clean up broken lesion fluid overflowing, and clean up blood stains from infusion.

[0017] 2. This device can perform controlled clamping, dragging, and cutting of diseased tissue.

[0018] 3. This device, through the setting of the ball head and the rotation of the suction tube via the Luer joint, drives the mating groove to rotate accordingly, thereby changing the position of the suction head rod and the ball head, realizing multi-directional adjustment of the suction head rod and the ball head, and making 360° selection of various orientations, so as to achieve the above-mentioned processing of targets that are not in the direct field of vision.

[0019] 4. This equipment is available in different diameters and lateral openings to accommodate the removal of lesions of varying degrees and with different precision requirements. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-3 This invention provides a technical solution: a disposable universal suction and cutting pliers, including a suction tube 1, a Luer connector 2, a connecting tube 3, a mating groove 4, a limiting end bracket 5, a handle 6, and a trigger 7. The side end of the suction tube 1 is connected to the Luer connector 2, which is connected to the connecting tube 3 via a tube body. The connecting tube 3 is located at the upper end of the handle 6 and is connected to an external suction / extraction mechanism. The handle 6 is equipped with a trigger 7, which is movable to the handle 6. By pressing the trigger 7, the position of the suction head rod 8 is changed, allowing the suction head rod 8 to be stretched and adjusted. A ball head 9 is fixed at the end of the suction head rod 8 facing away from the trigger 7, connecting the connecting tube 3 to the external... The adsorption mechanism is connected to the suction tube 1, which can perform suction and discharge work. When the suction tube 1 and the ball head 9 are separated, the connecting tube 3 is connected to the suction tube 1 through the Luer connector 2. Waste liquid is sucked up through the suction tube 1. When tissue extraction is required, the trigger 7 is pressed. The trigger 7 can drive the spring telescopic rod 12 to retract. The trigger 7 moves on the handle 6, which can drive the cooperating rod 11 to move accordingly. The suction head rod 8 is provided on the cooperating rod 11 through the rotating limit of the sleeve 10. When the sleeve 10 moves, it drives the suction head rod 8 and the ball head 9 to be lifted, so that the ball head 9 is squeezed and contacted with the suction tube 1, which can extract the tissue on the ball head 9 and the suction tube 1.

[0026] The rear end of the suction head rod 8 is connected to the limiting end frame 5, and the limiting end frame 5 is provided with a mating groove 4, through which the suction head rod 8 can be adjusted.

[0027] The straw 1 and the ball head 9 are connected in a movable manner. When the straw 1 and the ball head 9 are separated, the straw 1 is connected to the tissue through the Luer connector 2 and the connecting tube 3, which can remove bleeding and other liquid contaminants.

[0028] The suction head rod 8 is moved and adjusted by pressing the trigger 7, changing the position of the ball head 9. When the ball head 9 contacts the suction tube 1, it performs tissue occlusion and removal.

[0029] Ball head 9 is spherically shaped for omnidirectional cutting.

[0030] The mating groove 4 on the limiting end frame 5 is used to limit the suction head rod 8, so that the suction head rod 8 can be adjusted and moved along the mating groove 4.

[0031] The rear end length of the suction head rod 8 exceeds the mating groove 4 by 10cm.

[0032] The trigger 7 has a spring telescopic rod 12 at its rear end. The trigger 7 is telescopically connected via the spring telescopic rod 12. The bottom of the spring telescopic rod 12 is fixed to the handle 6. The upper end of the trigger 7 is fixedly provided with a cooperating rod 11. A sleeve 10 is fixedly connected to the cooperating rod 11. The suction head rod 8 is rotatably sleeved on the sleeve 10. The suction head rod 8 and the sleeve 10 can rotate relative to each other. The sleeve 10 can drive the suction head rod 8 to move laterally. The Luer connector 2 is provided with a knob. By turning it, the Luer connector 2 can be adjusted to change the angle of the Luer connector 2, so that the suction tube 1 can follow the angle adjustment. At this time, the suction head rod 8 and the ball head 9 can follow the position adjustment. The suction head rod 8 can rotate on the sleeve 10 to rotate in coordination, thereby changing the adjustment of the clamping position.

[0033] Working principle: When needed, the user connects the connecting tube 3 to the external suction mechanism for extraction. When the suction tube 1 and the ball head 9 are separated, the connecting tube 3 connects to the suction tube 1 via the Luer connector 2, allowing for the suction of waste liquid. When tissue extraction is required, pressing the trigger 7 causes the spring telescopic rod 12 to retract. The trigger 7 then moves on the handle 6, causing the cooperating rod 11 to move accordingly. The cooperating rod 11 is fitted with a suction head rod 8 via a sleeve 10 for rotational limitation. When the sleeve 10 moves, it pulls up the suction head rod 8 and the ball head 9, causing the ball head 9 to press and contact the suction tube 1, which can extract the tissue on the ball head 9 and the suction tube 1. At the same time, the Luer connector 2 is equipped with a knob, which can be turned to adjust the Luer connector 2 and change the angle of the Luer connector 2, so that the suction tube 1 can adjust its angle accordingly. At this time, the suction head rod 8 and the ball head 9 can adjust their positions accordingly. The suction head rod 8 can rotate on the sleeve 10 to cooperate with the rotation, thereby changing the clamping position adjustment work and completing the work.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
