Problems solved by technology

[0005] The above technical solutions, 1. There is no structure to prevent the same set of straws and push rods from being reused. If medical staff fail to replace the straws and push rods for reasons such as being in a hurry, problems such as cross-infection of germs may occur, which is not conducive to the treatment and rehabilitation of patients; 2. 1. The storage tank still needs to be cleaned. If it is not cleaned or the disinfection effect is not up to the medical requirements, it is easy to breed bacteria, which is not conducive to repeated use; It is not in place or is not firm enough to fall off, which affects the surgical effect; 4. The suction tube of the existing ligation device and other parts used to contact the lesion cannot achieve filtration, and cannot effectively prevent human tissue from being sucked into the vacuum pump during the negative pressure suction process

Embodiment Construction

[0061] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0062] Such as Figure 1 to Figure 15 As shown, an electric anorectal ligation device for reducing cross-infection of the present invention is in the shape of a gun as a whole and includes a handle and a ligation mechanism. The ligation mechanism is detachably connected to the handle, and the handle includes a left handle shell 11 and a The right handle shell 12, the left handle shell 11 and the right handle shell 12 are interlocked and assembled to form a gun shell. The handle is provided with a control mech...

Abstract

The invention discloses an electric anorectal loop ligature capable of reducing cross infection. The loop ligature comprises a handle, a ligation mechanism, a firing mechanism, a suction mechanism anda control mechanism. The ligation mechanism comprises an inner barrel, a push sleeve, a stringing assembly and a filter assembly. The push sleeve sleeves the inner barrel. The firing mechanism comprises a firing switch, a guide push block and a vent pipe top seat. The vent pipe top seat is fixedly connected in the handle, and the guide push block is in sliding connection to the vent pipe top seat. The firing switch is rotatably connected to the handle. The suction mechanism comprises a four-way pipe and a negative pressure pump. The four-way pipe is respectively communicated with the vent pipe top seat, the negative pressure pump, a pressure relief assembly and a sensor connection pipe. The control mechanism comprises a controller and a pressure sensor. The pressure sensor is disposed onthe inner wall of the inner barrel, and the pressure sensor is connected to the controller. The loop ligature can prevent medical staff from reusing a disposable assembly, can prevent foreign mattersfrom entering the matched handle, can avoid infection and is safe to operate.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an electric anorectal ligation device for reducing cross-infection. Background technique [0002] The common way to treat hemorrhoids is to use band ligation. The principle is to tie a special rubber ring on the root or base of hemorrhoids, and use the elastic retraction force of the rubber ring to block the blood supply of hemorrhoids, making them necrotic, shrinking, and falling off, so as to achieve cure. Objective: At present, the instruments used for ligation surgery generally use a ligation device, which absorbs the upper mucosa of female hemorrhoids through vacuum, and blocks the superior hemorrhoidal artery immediately after ligation with elastic threads, so as to achieve the purpose of minimally invasive hemorrhoids. [0003] Most of the existing ligation devices on the market are hand-held guns, which can only be used once. However, under the requirements of low cost and ...
