Uterus intracavity biopsy extractor

Abstract

The invention provides a uterus intracavity biopsy extractor. The uterus intracavity biopsy extractor includes a pipe, a first lifting part, a first clamping part, a second lifting part, a second clamping part, an expansion clamping part and a driving force part; the pipe is used for stretching into the uterine cavity of a patient; the sliding direction of the first lifting part on the pipe is perpendicular to the axle center of the pipe; the first clamping part is hinged to the first lifting part; the sliding direction of the second lifting part on the pipe is perpendicular to the axle center of the pipe; the second clamping part is hinged to the second lifting part and is used for cooperating with the first clamping part to clamp tumors; the expansion clamping part is arranged inside the pipe, is provided with a first slope and a second slope and is used for pushing the first lifting part to slide through the first slope and pushing the second lifting part to slide through the second slope when moving towards the uterine cavity, wherein the first slope is located at the side, facing the first lifting part, of the expansion clamping part, and the second slope is located at the side, facing the second lifting part, of the expansion clamping part; the driving force part is arranged at the side, away from the expansion clamping part, of the pipe and is used for driving the expansion clamping part to move towards or away from the uterine cavity inside the pipe.

Description

Technical field [0001] The invention relates to the field of treatment of gynecological tumor diseases, in particular to an intrauterine biopsy extractor. Background technique [0002] In order to minimize the degree of invasiveness to the patient, in cervical tumor surgery, a biopsy method is generally adopted for the lesion site first, that is, a small piece of diseased tissue is clamped and sent to the pathology department for film production. Determine the benign and malignant, and then decide the follow-up treatment. [0003] At present, in cervical tumor surgery, most of the clamping forceps are used to extend into the uterine cavity to grasp the tumor for biopsy. When the clamping forceps are used to extend into the uterine cavity, the uterine cavity incision needs to provide space for the opening and closing of the grasping forceps. , Resulting in large uterine incisions, slower recovery of patients after surgery, high wound infection probability, increased patient sufferi...

Problems solved by technology

[0003] At present, in the operation of cervical cavity tumors, most of the forceps are used to extend into the uterine cavity to grasp the tumor for biopsy. When the forceps are used to extend into the uterine cavity, the incision of the uterine cavity needs to provide space for the opening and closing of the forceps , leading to large incisions in the uterine cavity, slow recovery of patients after surgery, and a high probability of wound infection, which increases the pain of patients and reduces the work efficiency and quality of medical staff
