Description

A device for stopping bleeding through the end of anoscope during anorectal surgery

Technical Field

The utility model belongs to the technical field of anoscopes, and in particular relates to a hemostatic device that is used during anorectal surgery through the end of anoscope.

Background technique

Surgical hemostasis is generally divided into three forms: compression hemostasis, suture hemostasis and electrocoagulation hemostasis. For anorectal surgery, due to the anatomical characteristics of the anal canal itself, it is difficult to directly see the bleeding point deep in the anal canal under the surgical field of view. It often takes a long time to find the bleeding point during the operation, and even bleeding will occur. However, due to the deep location of the bleeding point, it is difficult to reach the bleeding site by suture hemostasis or electrocoagulation hemostasis. In the end, only compression hemostasis can be used, which can easily cause heavy bleeding in patients after surgery. In addition, most of the existing hemostatic equipment cannot easily adjust the size of the anus, making it inconvenient to use.

Utility Model Content

In view of the deficiencies in the prior art, the utility model aims to provide a hemostatic device through the end of anoscope during anorectal surgery, which has the advantages of effectively finding bleeding points and stopping bleeding in time.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for stopping bleeding through the end of an anoscope during anorectal surgery, comprising a fixed shell, a placement groove is provided inside the fixed shell, a threaded rod is rotatably connected inside the placement groove, one end of the threaded rod passes through one side of the fixed shell, the external thread of the threaded rod is connected to a threaded block, the external part of the threaded block is fixedly connected to a connecting block, two connecting rods are arranged at the bottom of the fixed shell, one of the connecting rods is fixedly connected to the bottom of the fixed shell, and the other of the connecting rods is fixedly connected to the bottom of the connecting block.

Preferably, the outside of the connecting rod is fixedly connected to a fixed block, the outside of the fixed block is fixedly connected to a first expansion plate, the inner side of the first expansion plate is fixedly connected to a connecting column, the outside of the connecting column is fixedly connected to a second expansion plate, and a lamp bead is arranged between the first expansion plate and the second expansion plate.

Preferably, the number of the connecting columns is four, and the four connecting columns are evenly distributed between the first expansion plate and the second expansion plate.

Preferably, the inner side of the first expansion plate is fixedly connected to a limiting slot plate, the interior of the limiting slot plate is provided with two correspondingly distributed sliding slots, the interiors of the two sliding slots are both slidably connected with sliders, an electric knife is fixedly connected between the two sliders, and the outside of the electric knife is fixedly connected to a pull rod.

Preferably, the first expansion plate and the second expansion plate are both configured to be arc-shaped, and the first expansion plate and the second expansion plate are fixedly connected via a connecting column.

Preferably, a sliding groove is provided at the bottom of the fixed shell, a sliding block is fixedly connected to the top of the connecting block, and the sliding block is slidably connected in the sliding groove.

Preferably, a handle is fixedly connected to the outside of the threaded rod, and the handle is made of rubber.

Compared with the prior art, the beneficial effects of the utility model are:

1. Hold the handle and rotate it, and then drive the fixed threaded rod to start rotating, and then drive the threaded block connected with the external thread to start moving, and at the same time drive the connecting block fixed at the bottom to start moving, and at the same time drive one of the connecting rods fixed at the bottom to move. When the connecting block moves, the sliding block fixed at the top slides in the sliding groove, making the movement more stable. Then, when the connecting rod moves, the first expansion plate and the second expansion plate are driven to move at the same time, so as to facilitate the adjustment of the size of the anal dilator and improve the flexibility of use.

2. After finding the bleeding point, the first expansion plate and the second expansion plate structure of the anoscope can extend out around the anoscope to grab the bleeding mucosa and the underlying blood vessels to play a role in compressing and stopping bleeding. If the bleeding blood vessels at that location are large and simple compression and hemostasis are not effective, the electric knife used in conjunction with the anoscope can also be used for electrocoagulation and hemostasis. Traditional electric knives are short and cannot stop bleeding deep in the anal canal. The electric knife of this patent can be pushed forward by a pull rod to perform electrocoagulation and hemostasis along with the anoscope for a week. When not in use, the pull rod can be pulled back into the first expansion plate and the second expansion plate of the anoscope. The mucosa and submucosal vascular tissue at the bleeding site can be hemostatically controlled by the electric knife.
