Abstract

A jaw assembly for endoscope biopsy forceps includes a jaw frame (1), two steel wires (2) with one end of each connected to a control rod, and a left jaw (3) and a right jaw (4) that are articulated with the jaw frame (1). The other end of one steel wire (2) passes through the left jaw (3), and a ball head (5) integrated with the steel wire (2) is provided on the steel wire (2) which passes through the left jaw (3). The diameter of the ball head (5) is greater than the diameter of a hole in the left jaw (3) and the hole allows the steel wire (2) to pass through. The other end of the other steel wire (2) passes through the right jaw (4), and a ball head (5) integrated with the steel wire (2) is provided on the steel wire (2) which passes through the right jaw (4). The diameter of the ball head (5) is greater than the diameter of a hole in the right jaw (4) and the hole allows the steel wire (2) to pass through. The invention can ensure firm connections between the steel wires and the jaws as well as convenient manufacturing.

Description

In the field of wood

The present invention relates to relates to the break in the lower inner. Background wood

The most commonly used in the West and the other end connected to the left-right Republican one end are left and right channels. The left and right of way to access the following

1, such that the portion can. Connection mode is to reduce the strength of the portion or portions may be detached and the partner access insecure.

2, the Z "make. Is Z" There are likely to use.

3, the use of her sealed. It Is content

This new object is to provide reliable connection, in the ease of manufacture.

The purpose of the program is to include a wooden termination of the West in the republic and left and right of access

One hundred to one hundred to one hundred pores larger than an upper right to upper left of the aperture is greater than one hundred to the other end of the right and the other having a break at the other end of the right and left have a break on the left.

Of wood having ordinary scheme to break a hundred to greater than the contact so firmly undesirable off ease of manufacture. But also to avoid the same hole where you can eliminate improve the safety of use.

This is Huett, and the performance by the following step.

1 a schematic force of this new store

The store 21

2 is a schematic enlarged three store

A force store 4 a schematic of the present novel contact store. This is the best way

The following Hopewell this new step.

1 as comprising a termination 1 and 2 West left contact 3 and the other end 42 left and right in FIG. 1 3 3 has left off in 5 of 23 and 5 hundred to greater than 2 on the left 3 hundred holes to the other end of the other 4 having two off right at the right 4 2 5 5 and one hundred to one hundred to greater than 4 on the right of the hole 2. 7 from the outer tube 6 and the outer tube 8 and the outer fixed contact 67 on the side of the tube 2 and 8 may be connected to the 8 2 7.

This novel works as follows by the object 2 to 8 such that the left and right harmony through the use of the finger 4 shown in FIG.

Claims

Requirements 1. In including Western 2 and a contact 3 left and right 1 one end 4 of which Laid wherein the hole left 3 2 having a rest 5 and 5 hundred to greater than the other end 2 of the 3 left on 2 left 3 2 to the other end of the other one hundred right 4 and 5 having a rest on the right 4 2
Five hundred to one hundred to greater than 4 on the right of the hole 2.
