Abstract
The invention relates to a pair of wide-angle biopsy forceps of an endoscope. The forceps comprise an operation handle, an elastic catheter and a jaw. A push-pull ring is arranged on the operation handle. The push-pull ring and the jaw are connected through a pull rope. A knob is arranged on the operation handle. A location control line is arranged between the knob and the jaw. A wire hole and a conductor wire ring are arranged on the elastic catheter. The location control line passes through the wire hole and the conductor wire ring and is connected with a connecting member at the rear end of the jaw. The wide-angle biopsy forceps of the endoscope disclosed by the invention have the benefits that: the elasticity of the control line is adjusted through the knob so that the bending angle and the bending direction of the jaw can be controlled; the forceps are convenient to sample in the process of diagnosing; and the forceps are simple in structure and convenient to operate.
Description
Technical field
The present invention relates to a kind of endoscope Radix Rumicis biopsy forceps.
Background technology
Patients' such as gastropathy diagnosis uses biopsy forceps to take a sample to check usually, to confirm pathology character; Existing biopsy forceps; The direction that binding clip is crooked is difficult to control with angle, and vice body and pathological tissues are parastate more, when esophagus or the little crooked position of body of stomach are taken a sample; Binding clip is difficult to accurately be positioned pathological tissues, the influence diagnosis; Though the endoscopic biopsy clamp headend that has can be crooked, complex structure, and operate constant.
Summary of the invention
The purpose of this invention is to provide a kind of endoscope Radix Rumicis biopsy forceps, regulate the control wire degree of tightness through knob, can control the crooked angle and direction of binding clip, sampling is simple in structure, easy to operate when being convenient to diagnose.
The objective of the invention is to realize through following technical scheme:
A kind of endoscope Radix Rumicis biopsy forceps; Comprise lever, elastic catheter and jaw, lever is provided with the push-and-pull ring, is connected through drag-line between push-and-pull ring and jaw; Lever is provided with knob; Be provided with the positional operand ordinate between knob and the jaw, elastic catheter is provided with line hole and conductor loop, and the positional operand ordinate passes the line hole and links to each other with conductor loop and with the connector of jaw rear end.
Beneficial effect of the present invention is: regulate the control wire degree of tightness through knob, can control the crooked angle and direction of binding clip, sampling is simple in structure, easy to operate when being convenient to diagnose.
Description of drawings
According to accompanying drawing the present invention is done further explain below.
Fig. 1 is the structural representation of endoscope of the present invention Radix Rumicis biopsy forceps;
Fig. 2 is a binding clip enlarged drawing among Fig. 1.
Among the figure:
1, lever; 2, elastic catheter; 3, jaw; 4, knob; 5, positional operand ordinate; 6, drag-line; 7, push-and-pull ring; 8, connector; 9, conductor loop; 10, spring; 11, line hole.
The specific embodiment
Shown in Fig. 1-2, the described a kind of endoscope of embodiment of the invention Radix Rumicis biopsy forceps comprises lever 1, elastic catheter 2 and jaw 3; Lever 1 is provided with push-and-pull ring 7; 3 of push-and-pull ring 7 and jaws are connected through drag-line 6, and lever 1 is provided with knob 4, is provided with positional operand ordinate 5 between knob 4 and the jaw 3; Positional operand ordinate 5 is worn cable-through hole 11 and is linked to each other with conductor loop 9 and with the connector 8 of jaw 3 rear ends, and the hole 11 of reaching the standard grade is arranged on the elastic catheter 2 with conductor loop 9; The positional operand ordinate 5 outer springs 10 that join with conductor loop 9 that are provided with.
Positional operand ordinate 5 two ends link to each other with connector 8 with knob 4 respectively, and during use, left and right adjusting knob 4 can be adjusted positional operand ordinate 5 degrees of tightness, thereby can the crooked angle and direction of wide-angle control binding clip.
