Description

Upper digestive tract hemostasis foreign matter removal assembly

Technical Field

The utility model belongs to the field of medical equipment, and particularly relates to an upper gastrointestinal hemostatic and foreign matter removing assembly.

Background

The gastroscope treatment is first selected for the treatment of acute upper gastrointestinal hemorrhage. During the treatment process, the conditions of observing treatment due to hematocele, blood clot or chyme in the digestive tract are often encountered. The existing method for removing foreign matters such as chyme, blood clots and the like in the upper digestive tract is to suck out the foreign matters such as chyme, blood clots and the like through a gastroscope pipeline; however, if the foreign matter is too large, the passage of the gastroscope tube is very narrow, and the foreign matter cannot be sucked out. And if the suction force of the gastroscope pipeline is too large, the bleeding condition at the hemostatic position can be aggravated. Another method for removing foreign matters in the upper digestive tract is to use a net bag and a gastroscope to enter the upper digestive tract together, and take out the foreign matters after the net bag is used for holding the foreign matters; however, when the method is used for taking the foreign matters, the foreign matters in the net bag easily collide with the alimentary canal wall, so that the foreign matters fall off and are dangerous if the foreign matters fall into the airway of a patient carelessly. Repeated entry and exit of the gastroscope also tends to cause damage to the wall of the digestive tract. Therefore, it is necessary to design an upper gastrointestinal hemostatic and foreign matter removing assembly which can solve the above problems.

Detailed Description

First embodiment: referring to fig. 1-5, an upper gastrointestinal hemostatic and foreign matter removing assembly comprises a gastroscope 1, a three-jaw forceps 2, a sleeve 3 and a transparent cap 4.

The gastroscope 1 is provided with a gastroscope tube 11. The end of the gastroscope tube 11 is provided with a camera, and the camera is electrically connected with the display screen, so that a picture shot by the camera is displayed on the display screen. A passage is arranged in the gastroscope tube 11, one end of the passage is arranged near the camera, and the other end of the passage is connected with the aspirator so as to suck out foreign matters in the upper digestive tract.

The sleeve 3 is in a strip tube shape, and the length of the sleeve 3 is the same as that of the gastroscope tube 11 of the gastroscope 1. The side surface of the sleeve 3 is fixedly connected with the side surface of the gastroscope tube 11 of the gastroscope 1. The outer surfaces of the gastroscope tube 11 and the sleeve 3 are both made of medical polymer materials so as to prevent damage to the upper digestive tract

The transparent cap 4 is fixedly connected to the end of the gastroscope tube 11. The side of the transparent cap 4 is provided with a through hole to prevent the upper digestive tract inner wall mucous membrane from being damaged due to the fact that the upper digestive tract inner wall is sucked by the passage of the gastroscope tube 11 when the upper digestive tract sucks foreign matters. The end of the transparent cap 4 connected with the gastroscope tube 11 is provided with a hole groove, and Kong Caoda is matched with the opening size of the passage of the gastroscope tube 11; the position of the hole and the groove are matched with the opening of the passage of the gastroscope tube 11.

The three-jaw pliers 2 comprise a core bar 21, a slip ring 22, a rotary cap 23, a connecting pipe 24 and a three-jaw pliers head 25. The connection pipe 24 includes an outer pipe and an inner pipe, the outer pipe is fixedly connected with the core rod 21 through a rotating cap 23, and the slip ring 22 is provided on the core rod 21 and slides in the axial direction thereof. The inner tube is arranged in the outer tube, a nickel titanium wire is arranged in the inner tube, one end of the nickel titanium wire is provided with a butt joint tube, and the nickel titanium wire is connected with the tail end of the three-jaw clamp head 25 through the butt joint tube; the other end of the nickel titanium wire extends into the core rod 21 and is connected with the slip ring 22, and a boosting pipe for pushing the inner pipe is arranged outside the nickel titanium wire extending into the core rod 21. The three-jaw clamp head 25 is composed of three jaws, and the ends of the jaws are all provided with solid end caps. Reference is made to the prior patent number CN201520223673.3 for specific technology to a rotatable claw-type foreign body forceps.

The connecting pipe 24 is arranged in the sleeve 3, and one end of the connecting pipe 24 connected with the three-jaw clamp head 25 extends out of the sleeve 3 and penetrates through a through hole on the side surface of the transparent cap 4, so that the three-jaw clamp head 25 is positioned in the transparent cap 4.

Working principle:

when the foreign matter on the upper digestive tract of a patient needs to be removed, one end of the product provided with the three-jaw forceps head 25 is inserted into the upper digestive tract of the patient, and the three-jaw forceps 23 are always positioned in the transparent cap 4 so as to prevent the inner wall of the upper digestive tract from being scratched to cause injury. When a camera of the gastroscope tube 11 is used for finding out foreign matters, the three-jaw clamp head 25 is controlled to stretch and open through the operation slip ring 22, when the three-jaw clamp head 25 needs to be rotated, the rotary cap 23 is fixed by one hand, the core bar 21 is rotated by the other hand, the nickel titanium wire is rotated, and then the three-jaw clamp head 25 is driven to rotate, and the nickel titanium wire can reduce the rotation resistance caused by bending of the head of the three-jaw clamp head 25. The three-jaw forceps head 25 is operated to crush the foreign matters, and then the aspirator is operated to suck the crushed foreign matters through the passage in the gastroscope tube 11.

Specific embodiment II: unlike the first embodiment, the three-jaw binding clip 25 is a three-jaw binding clip with a saw-tooth shape on the inner side. If the foreign matter is a rigid foreign matter, the three-jaw forceps head 25 can not be smashed, and the three-jaw forceps head 25 can be controlled to be closed to firmly clamp the foreign matter, and the gastroscope tube 11 is pulled out from the upper digestive tract of a patient and simultaneously taken out together.

Third embodiment: unlike the first or second embodiment, the two ends of the transparent cap 4 are in an open structure to communicate the inner channel of the gastroscope tube 11 with the outside of the transparent cap 4.
