Combined electric ligation injector

Abstract

The invention discloses a combined electric ligation injector which comprises a gun body, a sucker, a suction tube, a push tube, a push ring, a trigger and a negative-pressure suction device. The combined electric ligation injector is characterized in that a negative-pressure suction connector is arranged at the front end of the negative-pressure suction device, one end of the negative-pressure suction connector is communicated with a negative pressure pump, and the other end of the negative-pressure suction connector is connected with the suction tube detachably; the push tube is detachably connected with a pusher, a guide slot for guiding the pusher is formed in the inner wall of the gun body, and the trigger fits the pusher and is capable of driving the pusher to move when being triggered to further drive the push tube and the push ring to move so as to realize movement of a ligation rubber ring. The combined electric ligation injector has the advantages that since the suction tube and the negative-pressure suction connector as well as the push tube and the pusher are connected detachably, automatic negative-pressure suction and ligation rubber ring movement can be achieved; as the suction tube, the push tube, the sucker and the push ring are disposable consumables, raw materials are saved, manufacturing cost is reduced, patients' suffering is released, and the combined electric ligation injector is convenient to apply and popularize.

Description

technical field [0001] The invention relates to a combined electric ligation syringe, more specifically, to a material-saving combined electric ligation syringe with a replaceable push rod length and few parts to be replaced at one time. Background technique [0002] As a convenient medical treatment tool, the medical suction and injection ligation device is mainly used for the treatment of hemorrhoids. The patent number is CN200520081522.5, the invention patent document of the invention name is medical multi-energy suction injection ligation device, the patent number is CN200920030932.5, the invention name is also the patent document of medical multi-energy suction injection ligation device, and the patent number is CN201110170819.9 and the invention patent document titled Medical Injection and Sleeve Therapeutic Apparatus both disclose a medical device for treating patient lesions (such as hemorrhoids). The injection sleeve therapeutic apparatuses disclosed in these three...

AI Technical Summary

Problems solved by technology

The injection sleeve therapeutic apparatuses disclosed in these three documents all use fingers to pull the trigger for adsorption. Since the focus of the patient is to be adsorbed into the suction cup at the front end, and then the drug is injected and the rubber ring is ligated, the piston cavity must be required. There is a large negative pressure inside, which requires the doctor to pull the trigger with great force. For female doctors or thin male doctors, it is difficult to pull the trigger smoothly, so it is difficult to complete adsorption, injection and injection. ligation therapy

[0003] In order to overcome the disadvantages of inconvenient operation caused by manual vacuuming, the invention patent document with the patent number CN201410348987.6 and the invention name is Disposable Injection Ligation Therapeutic Device discloses a simple structure and low cost injection ligation Therapeutic device, which adopts suction vacuum pump for automatic vacuum suction, makes the whole injection ligation therapeutic device very convenient to use, and is also suitable for female doctors with very little strength to operate

For this type of treatment device, in the process of use, it is necessary to connect the negative pressure device with the gun body. If the twisting force is too small, it is easy to cause air leakage at the joint, and if the twisting force is too large, it is easy to cause joint damage. Fracture; due to the frequent use of the vacuum suction device, frequent connections are required, which may easily cause damage to the connection of the suction vacuum device

Furthermore, because the entire gun body is disposable, it will undoubtedly cause waste of materials; finally, because it uses a traction rope to drive the peripheral push tube to move, this driving form is cumbersome to assemble, which is not conducive to mass production

[0004] There are also shortcomings in the above-mentioned various forms of injection ligation therapeutic devices. For example, when treating patients with different depths of diseases (such as anorectal hemorrhoids, rectal polyps, rectal mucosal prolapse, etc.) according to clinical needs, it is necessary to use a long stick Interchangeable with short rods, but none of the existing injection ligation therapy devices can be interchanged with long and short rods, which cannot fully meet the needs of clinical treatment
