Technical Field

The invention relates to the technical field of medical treatment, in particular to a biopsy forceps fixing seat for a fiber bronchoscope.

Background

As is known, bronchoscopy consists in placing an elongated bronchoscope transorally or nasally into the lower respiratory tract of a patient, i.e. through the glottis into the trachea and bronchi and further distally, in observing lesions of the trachea and bronchi directly, and in carrying out corresponding examinations and treatments according to the lesions. Broadly included are bronchoscopic lesion biopsies, bronchial mucosa biopsies, bronchoscopic transmural lung biopsies (TBLB) and bronchoscopic Needle biopsies (TBNA). Most lung and airway diseases, such as tumors, interstitial lung diseases, granulomatous diseases and certain infectious diseases, require a definitive diagnosis by bronchoscopic biopsy and are the most commonly used examination.

Endoscopes used in examination are classified into rigid bronchoscopes (also called flexible bronchoscopes) and flexible bronchoscopes (also called rigid bronchoscopes). Bendable bronchoscopes are divided into fiberoptic bronchoscopes and electronic bronchoscopes.

Taking a fiberbronchoscope as an example, the operation method of bronchoscope biopsy is to adopt TBLB without X-ray guidance, which is mostly used for diffuse lesion of lung, and select the inferior lobe on the side with serious lesion, generally select 9 and 10 segments of the inferior lobe, and avoid the middle lobe. The operation method comprises the following steps: inserting the biopsy forceps into the selected section of the bronchial tube, withdrawing the biopsy forceps by 1-50 px when resistance is met, opening the biopsy forceps, ordering the patient to inhale deeply, advancing the biopsy forceps by 1-50 px when the resistance is met, ordering the patient to exhale deeply, clamping the biopsy forceps closed at the end of deep expiration, and slowly withdrawing the biopsy forceps. During the operation, if the patient feels chest pain, the biopsy forceps should be withdrawn, and the position should be replaced for another biopsy.

In actual operation, during the examination of the fiberbronchoscope, the biopsy forceps enter through the biopsy forceps perforation of the fiberbronchoscope operation part, after the biopsy forceps reach a preset position, in order to fix the biopsy forceps, the method generally adopted is to clamp the guide wire of the biopsy forceps by the hand of another doctor so as to avoid the biopsy forceps from shaking, the method of manually clamping the biopsy forceps not only needs to be operated by a specially-assigned person, but also is easy to shake, the end of the biopsy forceps in one point is moved greatly as long as the end of the biopsy forceps is shaken, so that the patient discomfort is caused by a light person, medical accidents and the like can be caused in serious cases, the working efficiency is greatly reduced, the labor intensity of the doctor is enhanced, and how to provide the biopsy forceps fixing seat for the fiberbronchoscope to replace the manual hand to fix the biopsy forceps is particularly important.

furthermore, in order to enable the invention to be suitable for fiberbronchoscopes of different models, a lower elastic sleeve perforation which penetrates through to the lower end of the biopsy forceps perforation 3 is arranged in the middle of the lower end face of the fixed seat body 1, a lower elastic sleeve 12 is sleeved in the lower elastic sleeve perforation, a conical fixing hole 10 which is small at the top and large at the bottom is arranged in the middle of the lower elastic sleeve 12, a limiting groove 11 is arranged at the upper part of the fixing hole 10, and when fiberbronchoscopes of different models are used, the invention can be realized by replacing the lower elastic sleeve 12 with the fixing hole 10 of different sizes and shapes;

furthermore, at least one opening 13 penetrating through the outer edge surface of the fixed base body 1 is arranged on the inner edge surface of the through hole of the lower elastic sleeve, locking mechanisms are arranged on the outer edge surfaces of the fixed base bodies 1 on two sides of the opening 13, when the opening 13 is arranged in a single shape, each locking mechanism comprises a rear locking lug 6, a front locking lug 7 and a locking bolt 8, the rear locking lug 6 and the front locking lug 7 are respectively arranged on the outer edge surfaces of the fixed base bodies 1 on two sides of the opening 13, screw holes are respectively arranged on the rear locking lug 6 and the front locking lug 7, and the two screw holes are connected through the locking bolt 8; or the back locking lug 6 is provided with a unthreaded hole, the front locking lug 7 is provided with a screw hole, and the unthreaded hole is connected with the screw hole through a locking bolt 8; or the rear locking lug 6 is provided with a screw hole, the front locking lug 7 is provided with a unthreaded hole, and the screw hole is connected with the unthreaded hole through a locking bolt 8; when a plurality of openings 13 are arranged, the locking mechanism is a hoop, and the locking bolt on the hoop is a claw butterfly bolt; when the locking mechanism is a hoop, an annular hoop fixing groove is formed in the outer edge surface of the lower portion of the fixing seat body 1, and the hoop is sleeved in the hoop fixing groove; the locking bolt 8 is a claw butterfly bolt.

Further, be equipped with arcwall face 9 at the lower extreme of fixed pedestal 1, during the implementation, the lower terminal surface interval of arcwall face 9 is equipped with a plurality of sucking discs 14, and sucking discs 14 can adsorb on the fiberbronchoscope, and then increase the firm degree that fixed pedestal 1 is connected with the fiberbronchoscope, the left end of arcwall face 9 corresponds spacing groove 11 and forms the biopsy forceps fixing base for the fiberbronchoscope.

When the fixed base body is specifically implemented, at least two binding bands can be arranged on the outer edge surface of the lower end of the fixed base body 1 at intervals, one end of each binding band is fixed to the rear portion of the outer edge surface of the lower end of the fixed base body 1, the other end of each binding band is provided with a buckle, and each buckle is respectively clamped in a clamping groove formed in the front portion of the outer edge surface of the lower end of the fixed base body 1.

The fixing seat body 1 can fix the length of the guide wire entering the fiberbronchoscope on the biopsy forceps, the length of the guide wire entering the fiberbronchoscope on the biopsy forceps can be determined only after the puller bolt 5 is fastened, after the operation is completed, the puller bolt 5 does not need to be loosened, only the locking mechanism needs to be loosened to separate the fiber bronchoscope from the biopsy forceps, and when the fiber bronchoscope is needed to be used next time, the guide wire entering length on the biopsy forceps does not need to be adjusted back and forth.

The specific using method of the invention is that firstly the locking mechanism on the fixed base body 1 is loosened, then the lower part of the fixed base body 1 is sleeved on the biopsy forceps support on the fiber bronchoscope, then the locking mechanism firmly fixes the fixed base body 1 on the fiber bronchoscope, if the sucker 14 is arranged under the arc surface 9 and is adsorbed on the fiber bronchoscope, the firm degree of the invention connected with the fiber bronchoscope can be effectively increased, if the fixed base body 1 is provided with a bandage, the invention is tied on the fiber bronchoscope through the bandage, the firm degree of the invention connected with the fiber bronchoscope can also be effectively increased, then the guide wire on the biopsy forceps sequentially passes through the biopsy forceps perforation 3 and the biopsy hole on the fiber bronchoscope, when the guide wire on the biopsy forceps reaches a preset position, the puller bolt 5 is screwed, the guide wire on the biopsy forceps is firmly fixed in the biopsy perforation forceps 3, therefore, the guide wire can be positioned without a doctor holding the biopsy forceps by the guide wire, and after the operation is finished, the locking mechanism is directly loosened to separate the fiberbronchoscope from the fiberbronchoscope.

The present invention is not described in detail in the prior art.

The embodiments selected for the purpose of disclosing the invention, are presently considered to be suitable, it being understood, however, that the invention is intended to cover all variations and modifications of the embodiments which fall within the spirit and scope of the invention.
