Description

Diagnosis and treatment biopsy forceps under choledochoscope

Technical field

The utility model relates to diagnosis and treatment biopsy forceps under choledochoscope more particularly to choledochoscope.

Background technique

Choledochoscope is widely used in hepatobiliary disease Clinics and Practices, and biopsy forceps is its primary treatment accessory, is mainly used for Clamp clamping tumor tissues or the benign tumour or polyp of suspicious canceration send histopathological examination, and can clamp take out in biliary tract Helminth, foreign matter, calculus, floccule and blood clot.However traditional biopsy forceps has the following disadvantages: 1, cannot accurately control The angle that clamp opens, therefore tissue cannot accurately be clamped according to the size of choledochoscope undertissue, it is difficult to increase operation Degree and time, it is easy that clamp tissue excessively causes surface of a wound bleeding or clamp is very few pathogenic manages inaccurate (false negative) when biopsy；2, living Inspection clamps no electrode interface, cannot timely electric coagulation hemostasis in biopsy forceps clamping tissue surface of a wound bleeding, it is also necessary to assistant is operated, Or other hemostat devices are needed replacing, so that cumbersome；3, biopsy jaw surfaces do not have length scale and mark smooth insulation Casing increases the friction with the sheath of choledochoscope service aisle, increases so that the sheath of choledochoscope is lost, reduced lifetime.

Summary of the invention

Utility model aims to solve the above problem in the prior art, diagnosis and treatment biopsy forceps under choledochoscope is provided.

In order to achieve the above objectives, the utility model adopts the following technical solution:

The metal inside is arranged in cavity and insulating sleeve, and one end of metal inside and one end of electrode contact connect It connects, the other end of metal inside is hinged by connection sheet and binding clip；

The binding clip is equipped with clamp, and the opening angle of scale and clamp on the scale strip is at preset proportionate relationship.

The binding clip is additionally provided with articulated section, and articulated section and clamp are integrally formed, and the angle of articulated section and clamp is greater than 90 °, the middle part of articulated section and insulating sleeve are hinged, and the end of articulated section and one end of connection sheet are hinged, the other end of connection sheet It is hinged with metal inside.

The opening angle of the clamp is 0~60 °；Preferably, the opening angle of the clamp be 15 °, 30 °, 45 ° and 60°。

The insulating sleeve is the smooth insulating sleeve marked with length scale.

The metal inside is in the shape of a spiral.

The flexible handle can be equipped with the first grip part, and first grip part is symmetrically set in the two sides of flexible handle；Institute The first grip part is stated as annular grip part.

One end of the fixed handle can be equipped with the second grip part；Second grip part is annular grip part.

The utility model can control the opening angle of clamp according to the size reasonable of choledochoscope undertissue, can be more acurrate Realize the clamp to tissue in ground.And biopsy forceps is equipped with electrode interface, when isotonic Glucose Liquid is perfused into bile duct for choledochoscope When, biopsy forceps can accurately clamp polyp the base of a fruit in bile duct or gall-bladder and polyp is taken out in coagulation cutting in time, and ensures that the surface of a wound does not go out Blood；When hematobilia, biopsy or other surgical wound surface bleedings, can add with norepinephrine Glucose Liquid irrigation, to After getting a clear view, biopsy forceps does not open the closed surface of a wound that touches and rides control electric coagulation hemostasis in time, can sufficiently liberate operation assistant, Shorten the operating time；Biopsy jaw surfaces, which are equipped with, marks smooth insulating sleeve with length scale, knows that biopsy forceps is inserted at any time Length reduces the friction repeatedly with the sheath of choledochoscope service aisle, protects sheath, reduces the electric injury and friction damage of sheath Wound；Realize that more acurrate, quickly and efficiently tissue forceps takes, polypectomy, the surface of a wound stop blooding.

Compared with the existing technology, the beneficial effect that technical solutions of the utility model obtain is:

1, the utility model keeps flexible handle elastic to control relative to fixed handle by sliding flexible handle The opening and closing of clamp；Scale strip is set on fixed handle, and with the same direction in the second grip part, operator can be convenient The scale on scale strip is observed on ground, so as to reasonably control clamp needs according to size and scale in kind under choledochoscope The angle of opening, can it is more acurrate, quickly and efficiently realize to the forceps biopsy of tissue and clamp take out helminth in biliary tract, Foreign matter, calculus, floccule and blood clot.

2, the utility model on flexible handle be equipped with electrode contact, the electrode contact can directly with external electrode electric knife Host is connected, and the mobile electrode contact that will drive of flexible handle is mobile, can pass through external electrode after accurately clamping polyp the base of a fruit Foot-operated control row cutting polyp and is taken out at once, avoids electric injury in operation or cutting tissue imperfect.When discovery biliary tract goes out Blood, biopsy or other operation the surface of a wound bleedings when, also can prompt, effective and adequate hemostasis, thus sufficiently liberation operation assistant, reduce Operating procedure shortens operating time, and reduces operation cost, to mitigate the financial burden of patient.

3, the insulating sleeve is the smooth insulative pipe sleeve with length scale, can be effectively protected and reduce biliary tract The various losses of mirror service aisle sheath, extend the service life of choledochoscope.
