Embodiment 1

[0032] Such as figure 1 figure 2 ,and Figure 6 As shown, a biopsy forceps with a measuring piece includes: a hard handle 1, a steel wire tube, a forceps head, a first sliding buckle, a second sliding buckle, and a measuring piece.

[0033] The hard handle 1 can be made of a certain hardness and smooth material such as plastic and meets the requirements of medical equipment. The hard handle 1 includes a pull ring, a cylindrical body, and a tapered barrel 1-3, wherein the cylindrical body Divided into the first cylindrical body 1-1 and the second cylindrical body 1-2, the direction from the rear end to the front end, the pull ring, the first cylindrical body 1-1, the second cylindrical body 1-2, the cone The shaped cylinders 1-3 are connected successively. The first cylindrical body 1-1 is provided with a hollow chute, the second cylindrical body 1-2 is cylindrical, and the cylindrical body and the tapered cylinder 1-3 are integrally formed.

[0034] The first sliding buck...

Embodiment 2

[0040] This embodiment is the same as Embodiment 1 except the following technical features.

[0041] Such as image 3 and Figure 5 As shown, the plane where the waist-shaped measuring piece is located is perpendicular to the plane formed by the opening angle of the pliers. In the axial direction of the tong shaft, the measuring piece goes around both ends of the tong shaft. The measuring piece in this embodiment does not pass through the pliers, and the pliers are not provided with corresponding holes. The end of the wire pipe extending into the tapered tube is wedge-shaped (not shown in the figure), and the front end of the second slide buckle is provided with a wedge (not shown in the figure) that is fixedly connected with the second slide buckle. The shape of the wedge is adapted to the wedge-shaped end of the steel pipe, and the top of the wedge is a rounded corner with a smooth transition.

[0042] One side of the measuring piece is provided with 1mm-wide bumps 8-1 a...

Embodiment 3

[0044] This embodiment is the same as Embodiment 1 except the following technical features.

[0045] Such as Figure 4 As shown, the plane where the waist-shaped measuring piece is located is parallel to the plane formed by the opening angle of the pliers head, but the two planes do not coincide. The measuring piece and the pliers of this embodiment can work independently, that is, the opening and closing of the pliers does not affect the stretching or retracting of the steel wire tube of the measuring piece, the measuring piece of this embodiment does not penetrate the pliers, and the pliers do not Corresponding holes are not provided.

Abstract

The invention relates to biopsy forceps with a measuring piece. The forceps comprises a hard handle, a steel wire pipe, a forceps head, a first slide buckle, a second slide buckle and the measuring piece. The hard handle, the steel wire pipe and the forceps head are successively connected. The first slide buckle is slidably installed on the hard handle and is connected with the forceps head via a first steel wire. The second slide buckle is slidably installed on the hard handle. The second buckle which controls the measuring piece to extend out or retract to the steel wire pipe is connected with the measuring piece via a second steel wire. Projections are arranged on the inner surface of the second slide buckle. Grooves in the peripheral direction are arranged in the peripheral side face contacting the inner surface of the second slide buckle of the hard handle. The projections match the grooves which are uniformly arranged in the axial direction of the hand handle. According to the invention, size of a focus can be measured and the biopsy forceps belong to the field of medical devices of endoscopes.

Description

technical field [0001] The invention relates to the field of endoscopic medical instruments, in particular to a biopsy forceps with a measuring piece. Background technique [0002] As a method of auxiliary diagnosis, endoscopic examination is used more and more widely in clinical medical examination. Biopsy forceps can be inserted into the patient's body through the endoscopic forceps channel to inspect the lesion and clamp the lesion tissue. In clinical practice, endoscopists mostly estimate the size of lesions based on clinical experience, and cannot accurately measure the size of lesions. The application document with application number 201420596758.1 discloses a biopsy forceps. The principle of the biopsy forceps is to arrange corresponding measuring wires in the clamps, and the measuring wires are distributed along the clamps; the biopsy forceps is used to measure the diameter of the trachea. However, the technology disclosed above cannot measure the size of the lesion...
