Description

Biopsy forceps with adjustable operation position and direction

Technical Field

The utility model relates to the field of medical equipment, specifically be a biopsy forceps of adjustable operating position and direction, be applicable to and take out patient's pathological change tissue or biopsy in the endoscopy.

Background

In clinical medical examinations, endoscopy has been widely used as a method for assisting diagnosis. The biopsy forceps can enter a patient body through the endoscope, the endoscope is mainly used for indirect observation and examination in the patient body, when a suspicious part needs to be further examined and confirmed, the biopsy forceps are often required to enter a cavity of the patient body from an endoscope pipeline to take down a small amount of living tissues of the suspicious part to be used for pathological section examination, and lesion tissues are clamped, so that pathological basis is provided for diagnosis.

Because the flexibility of the forceps head of the existing biopsy forceps is limited, the problem that the forceps head can not be accurately positioned during biopsy exists. In the early stage of the diseased tissue, because the target is small, edema may exist around the diseased tissue, or at the position which is difficult to reach by a biopsy forceps, such as the posterior wall of the stomach body, the position of the intestinal orifice and the like, the use of the biopsy forceps to take the diseased tissue has certain blindness, and an accurate result cannot be obtained. In addition, when the angle between the biopsy forceps and the diseased tissue is inappropriate, the diseased tissue cannot be grasped accurately. There is therefore a need for a bioptome that can be operated externally to adjust the position and orientation of the operation to allow for accurate positioning.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve the problem that current biopsy forceps can not realize adjustment operating position and direction with accurate positioning, provide a biopsy forceps of adjustable operating position and direction.

The utility model discloses a realize through following technical scheme: a biopsy forceps capable of adjusting an operation position and an operation direction comprises a handle and a forceps head part, wherein the handle comprises a fixed part and a control part, the forceps head part comprises a forceps head and a bent part, a cavity is arranged in the middle of the control part, the control part is sleeved with a control handle, the control handle is connected with the forceps head part through a guide wire in a guide pipe, a position and direction adjusting frame is fixedly arranged outside the control part and positioned at the lower part of the control handle, a control knob is also arranged in the position and direction adjusting frame and sleeved outside the control part, and the guide wire penetrates through the center of the control knob and is fixedly connected with the control knob; the control knob moves back and forth along the guide wire direction in the position direction adjusting frame to adjust the curvature of the bending part at the forceps head to reach the target tissue position, and the control knob adjusts the direction of the forceps head through rotation.

The utility model provides a biopsy forceps can adjust operation position and direction, it mainly realizes this function through control knob, adjust direction and position of operation respectively through control knob's rotation and pulling, among the prior art, biopsy forceps generally all include handle and binding clip portion, the handle includes fixed part and control part, the fixed part is for making the power point, general concrete operation and part all are located the control part, the control handle has been overlapped to the control part outside, the control handle passes through the seal wire in the pipe and is connected with the binding clip, make the binding clip come the live body tissue through pulling control handle, the binding clip portion includes binding clip and flexion, the flexion is also a part of pipe; and a position direction adjusting frame is fixedly arranged at the lower part of the control handle and outside the control part, a control knob is arranged in the position direction adjusting frame, the control knob is sleeved outside the control part, meanwhile, the guide wire passes through the center of the control knob and is fixedly connected with the control knob, the control knob can move axially along the guide wire in the adjusting frame, so that the bending part of the catheter is pulled to be bent to adjust the operation position, and meanwhile, the control knob can be rotated to enable the guide wire to rotate in the catheter to adjust the operation direction. The utility model discloses the specific operation does: when the forceps head and the catheter of the biopsy forceps extend into a cavity or an organ with pathological changes of a patient, the forceps head reaches a focus by observing the endoscope, the control knob is pulled to move in the position and direction adjusting frame, so that the guide wire is pulled, the bending part is bent, the operation position of the forceps head is adjusted, then the control knob is rotated according to the condition, the operation direction is adjusted, when the target tissue is aligned, the control handle is pulled to move outside the control part, the distance between the control handle and the fixing part is shortened, and the forceps head is enabled to clamp the pathological changes and then taken out.

Compared with the prior art the utility model discloses following beneficial effect has: the utility model provides a biopsy forceps of adjustable operating position and direction has solved current biopsy forceps and can not realize adjusting operating position and direction simultaneously, is difficult to the problem of accurate positioning, and this utility model discloses an angle through crooked biopsy binding clip for the in-process is got to the clamp in biopsy, with reach binding clip and the laminating of tissue, the accurate pathological change tissue of getting, make things convenient for more in doctor's operation, be a huge progress to current biopsy forceps operation, can use widely.
