Hysteroscope and biopsy forceps integrated cannula device capable of preventing falling during biopsy

Abstract

The invention relates to the field of medical apparatus and instruments, in particular to a hysteroscope and biopsy forceps integrated cannula device capable of preventing falling during biopsy. The hysteroscope and biopsy forceps integrated cannula device comprises a cannula I, a hysteroscope, a cannula II, a claw sleeve, a drawing wire ring, a drawing wire sleeve, a drawing wire, a sleeve shell, a guide tube, a ratchet top tray I, a ratchet top tray II, a spring I and a biopsy forceps structure. Three states of the claw sleeve in the device correspond to three stages of biopsy grasping of biopsy forceps in a targeted mode correspondingly. In the folded state of the first state, the biopsy forceps are shrunk in the cannula I before grabbing. The claw sleeve in the second state has the elastic opening characteristic, so that the claw sleeve can be automatically opened when stretching out, biopsy tissues grabbed by the biopsy forceps can be covered in the claw sleeve, and the opening type after elastic opening can cover the biopsy tissues with different sizes in a universal mode. In the third state, an end opening of the front end of the claw sleeve is pulled back by the drawing wire to be tightened and closed to be close to a sealing opening, so that the clamped biopsy tissue is completely wrapped, and double guarantees are achieved for preventing the biopsy tissue from falling off.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a hysteroscopic biopsy forceps integrated sleeve device capable of preventing biopsy from falling off. Background technique [0002] Hysteroscopy is a new minimally invasive gynecological diagnosis and treatment technology. It is a kind of fiber light source endoscope used for inspection and treatment of uterine cavity, including hysteroscope, energy system, light source system, perfusion system and imaging system. It uses the front part of the mirror body to enter the uterine cavity, and has a magnifying effect on the observed parts. It is intuitive and accurate and has become the preferred inspection method for gynecological hemorrhagic diseases and intrauterine lesions. Through hysteroscopy, a series of detection and treatment such as examination, diagnosis and analysis are carried out on women. Hysteroscopy and surgery are the best options for determining whether there are les...

AI Technical Summary

Problems solved by technology

Most biopsy forceps are limited to a single sample due to increased surgical difficulty and time due to the limited space between the two jaws of the biopsy forceps

[0004] 2. When the existing biopsy forceps are in the process of grasping the biopsy inside the uterine cavity, when encountering larger tissues, it often occurs that the biopsy forceps are too small or the clamping force is insufficient to cause the biopsy tissue to fall from the biopsy forceps during the removal process. Slippage, leading to tissue sampling failure, often requires doctors to re-access the biopsy forceps device to clamp the diseased biopsy tissue, which greatly affects the efficiency of the operation, prolongs unnecessary operation time, and is also a pain for the patient

[0005] 3. At present, the jaws of biopsy forceps on the market are designed with different serrations or jaw shapes, which are used for different biopsy situations, but there is no double protection for the biopsy forceps to prevent falling off, and the biopsy tissue may fall off. re-access gripping
