Description

gallbladder polypectomy device

technical field

The invention relates to a medical device, in particular to a device used in human gallbladder polypectomy or extirpation.

Background technique

Most gallbladder polyps are benign, and the proportion of adenomas in cholecystectomy specimens is only 1.1%, while the malignant transformation rate is 1.5%, which is considered to be the precancerous lesion of gallbladder cancer, so gallbladder polyps are rarely malignant, and currently clinically It is unscientific to perform cholecystectomy for benign lesions. For the consideration of protecting gallbladder function and avoiding long-term complications after cholecystectomy, cholecystectomy is not necessarily performed for the treatment of gallbladder polyps. The recurrence rate of "endoscopic minimally invasive gallbladder preservation and polyp extraction" method is only 1%. During the operation, the polyps are removed under the direct vision of the choledochoscope, and the polyps with objections are immediately sent for frozen pathological biopsy. If they are malignant, the gallbladder is performed. Excision is radical, and if the gallbladder is benign, the gallbladder is preserved, which avoids the fate of most benign polyps from gallbladder removal. This method decides whether to remove the gallbladder according to the pathological properties of gallbladder polyps, and is considered to be the most reasonable and scientific treatment method in the clinical practice of biliary tract surgery.

Among the existing instruments used for this type of operation, biopsy forceps are more common, and there are many deficiencies in the use and clinical application of biopsy forceps:

1. In the grasping of gallbladder polyps, it is necessary to adjust the position repeatedly, which not only affects the surgical field of view, but also artificially increases the difficulty of grasping to a certain extent;

2. In the process of polypectomy, the gallbladder polyp needs to be clamped for a long time, and it is necessary to wait for the clamped polyp to coagulate before releasing it after power on;

3. According to the different physiques of the users, some patients may experience secondary bleeding during the loosening process after coagulation, which requires further hemostasis, which increases the operation time;

Contents of the invention

The present invention aims at the above problems, and develops a new gallbladder polypectomy device, aiming to solve the problems in the prior art.

Technical solution of the present invention is realized like this:

A gallbladder polypectomy device is characterized in that it includes a cylindrical outer sleeve, an operating end, a limiting plate, a metal wire, and a "V"-shaped clamp; the operating end is installed on the limiting plate; the limiting plate is installed on the In the groove at the bottom end of the inner wall of the cylindrical outer casing, the limiting plate can move up and down or rotate in the groove; the metal wire is installed in the cylindrical outer casing, one end is connected with the limiting plate, and the other end is connected with the "V"-shaped clip Clamp connection; the "V"-shaped clamp is installed on the outside of the cylindrical outer casing, and the bottom end of the "V"-shaped clamp is connected to the metal wire; pull the operating end, and install the limit plate connected to the operating end in the groove. It moves accordingly, and drives the metal wire to move; while the metal wire moves, it drives the "V"-shaped clamp to retract into the cylindrical outer sleeve.

A high-frequency generator socket is installed on the side wall of the cylindrical outer casing, and the high-frequency generator socket is connected with the metal wire in the cylindrical outer casing through wires.

The lower end of the cylindrical outer sleeve is a hard part, and the front end is a soft part.

A handle assembly is installed on the hard part at the lower end of the cylindrical outer sleeve.

The "V"-shaped clamp can be completely merged into the cylindrical outer sleeve after the operating end is retracted.

The advantages of the present invention are evident due to the adoption of the above technical scheme:

1. The present invention adopts a clamp-type design, which can be used for effective clamping in different affected areas;

2. The present invention adopts the installation design of the limit plate, and the angle can be adjusted freely on gallbladder polyps that cannot be resolved, which is convenient for clamping and avoiding repeated adjustments;

3. The present invention is equipped with an external socket, which can be used in conjunction with a high-frequency electronic generator to achieve a more convenient effect under current medical conditions;

4. The present invention utilizes a pull-out structure for operability, which is simple in operation, saves operation time and improves work efficiency.
