Description

Thoracoscope esophagus grasping forceps

Technical Field

The invention relates to a thoracoscope esophageal grasping forceps, and belongs to the technical field of medical instruments.

Background

Minimally invasive endoscopic (thoracoscopic and laparoscopic) surgery is widely applied to the fields of thoracic surgery, general surgery, obstetrics and gynecology, urinary surgery and the like because of the advantages of small wound, light pain, less bleeding and short hospitalization time. The development of minimally invasive endoscopic surgery benefits from the use of an endoscopic system and endoscopic instruments to a great extent, such as a high-definition camera, various graspers, a blood vessel closer, an ultrasonic knife, and the like. However, in the combined esophago-cancer radical operation of the thoraco-laparoscope, when the esophagus is dissociated through the thoracoscope, the used instruments are still laparoscope instruments, wherein grasping forceps such as stomach forceps, intestinal forceps and the like cannot meet the requirement of complete grasping of the esophagus in the operation due to the problems of short forceps head and small radian of the forceps head, so that the esophagus is damaged or tumors are scattered easily; in addition, after the circumference of the small esophageal bed is opened, the esophagus is generally sleeved by a sterile rope, and then the rope is pulled by using a grasper to pull the esophagus to be exposed. The prior laparoscope instrument can not meet the requirement of thoracoscope esophagus dissociation.

Disclosure of Invention

The invention aims to solve the technical problem that the existing laparoscope instrument cannot meet the requirement of thoracoscope esophagus dissociation.

In order to solve the problems, the invention adopts the technical scheme that 1, the thoracoscope esophageal grasping forceps are characterized in that: comprises a tong head, a rotating shaft and a tong handle; the clamp head is connected with the clamp handle through a rotating shaft; the binding clip comprises two arc-shaped binding clip, one end of the two arc-shaped binding clip is connected with the rotating shaft, and the other end of the two arc-shaped binding clip is provided with mouse teeth.

Preferably, one end of each of the two arc-shaped forceps supports, which is far away from the rotating shaft, is provided with corresponding mouse teeth which can be meshed with each other.

Preferably, one ends of the two arc-shaped forceps branches, which are provided with the mouse teeth, are close to each other to form a hollow shuttle-shaped space.

Preferably, the inner side surfaces of the corresponding forceps legs of the two arc-shaped forceps legs are provided with small teeth.

Preferably, the small teeth are arranged in a staggered arrangement.

Preferably, the forceps handle is provided with a ring and a forceps buckle for adjusting the closing and biting force of the forceps head.

Preferably, the distance in the longitudinal direction of the shuttle space is 5cm or more, and the distance in the width direction of the shuttle space is 1cm or less.

Compared with the prior art, the invention has the following beneficial effects:

reasonable structure, convenient clinical popularization, economy, practicality and easy operation.

Detailed Description

In order to make the invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings:

as shown in figures 1-4, the invention provides a thoracoscope esophageal grasping forceps, which comprises a forceps head 1, a rotating shaft 4 and a forceps handle 5; the tong head 1 is connected with a tong handle 5 through a rotating shaft 4; the binding clip 1 comprises two arc-shaped binding clips, one ends of the two arc-shaped binding clips are connected with the rotating shaft 4, and the other ends of the two arc-shaped binding clips are provided with mouse teeth 2. One end of each arc-shaped forceps support, which is far away from the rotating shaft, is provided with a corresponding mouse tooth 2 which can be meshed with each other. One ends of the two arc-shaped forceps branches, which are provided with the mouse teeth 2, are close to each other and closed to form a hollow fusiform space. The inner side surfaces of the corresponding forceps branches of the two arc forceps branches are provided with small teeth 3. The small teeth are arranged in a staggered way. The forceps handle 5 is provided with a ring 6 and a forceps buckle 7 for adjusting the closing and biting force of the forceps head. The distance in the longitudinal direction of the shuttle space is set to be not less than 5cm, and the distance in the width direction of the shuttle space is set to be not more than 1 cm.

The invention provides thoracoscope esophageal graspers, aiming at the condition that the existing laparoscopic instrument cannot meet the requirement of thoracoscope esophageal dissociation. According to the esophageal forceps, the mouse teeth 2 are arranged at the top of the forceps head 1, the mouse teeth 2 are perpendicular to the forceps head 1, the mouse teeth 2 are occluded and fixed when the forceps head 1 is closed, and the small teeth 3 are attached to the inner side face of the forceps head 1, so that the grasping force of the grasping forceps is increased. After opening the mediastinum pleura in the operation, get through the circumference of the small segment of esophagus bed, the grasping forceps completely grasp the esophagus for 8 whole weeks to draw and expose, which is convenient for the dissociation of the esophagus 8 and the cleaning of lymph nodes. The binding clip 1 is connected with the binding clip handle 5 through the rotating shaft 4, the binding clip handle 5 is provided with a ring 6 and a binding clip 7, and the size of the closed biting force of the binding clip can be adjusted. After the forceps head 1 is occluded, a fusiform shape is formed between the two forceps branches, the maximum distance (including the thickness of the forceps branches) a between the two forceps branches is 1cm, and the distance b between the top of the forceps head and the joints of the grasping forceps is 5cm, so that the grasping forceps can completely grasp the whole periphery of the esophagus 8.

Referring to fig. 1, 2 and 3, the thoracoscope esophageal grasping forceps comprise a forceps head 1, a rotating shaft 4 and a forceps handle 5. After the forceps head 1 is occluded, a fusiform shape is formed between the two forceps branches, the maximum distance (including the thickness of the forceps branches) a between the two forceps branches is 1cm, and the distance b from the top of the forceps head 1 to the joint of the grasping forceps is 5 cm. The top of the binding clip 1 is provided with mouse teeth 2 and small teeth 3 on the inner side surface of the binding clip, the top of the binding clip 1 can be fixed after the mouse teeth 2 are occluded, and the small teeth 3 on the inner side surface of the binding clip can be arranged in a staggered way to increase the gripping force on the esophagus. After opening the mediastinum pleura in the operation, get through the circumference of the small segment of esophagus bed, the grasping forceps completely grasp the esophagus for 8 weeks, and the traction exposure is carried out, so that the esophagus dissociation and the lymph node cleaning are facilitated. The binding clip 1 is connected with the binding clip handle 5 through the rotating shaft 4, the binding clip handle is provided with a finger ring 6 and a binding clip 7, and the size of the closed biting force of the binding clip can be adjusted.

While the invention has been described with respect to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. Those skilled in the art can make various changes, modifications and equivalent arrangements, which are equivalent to the embodiments of the present invention, without departing from the spirit and scope of the present invention, and which may be made by utilizing the techniques disclosed above; meanwhile, any changes, modifications and variations of the above-described embodiments, which are equivalent to those of the technical spirit of the present invention, are within the scope of the technical solution of the present invention.
