Abstract

By attaching this cylinder to a standard forceps when conducting endoscopic surgery using such instruments as a laparoscope or a thoracoscope, and by placing this cylinder behind tissue and illuminating the blood vessels of the organ (stomach, large intestine, small intestine, esophagus and the like) having a lesion to be resected, it is possible to see through the blood vessels of the tissue. Thus, the blood vessels of the target lesion can be more accurately ascertained. A suction function of the cylinder suctions blood, and the cylinder also has a function for injecting a physiological saline solution and washing, and excluding and avoiding a tissue. With this configuration, the target lesion can be safely resected and the resection time can be shortened. When conducting endoscopic surgery using such instruments as a laparoscope or a thoracoscope, this cylinder (1) is attached to a standard forceps inserted into an insertion port of a laparoscope or a thoracoscope. The cylinder and forceps are inserted into the abdominal cavity or the thoracic cavity and placed behind the target organ, and by causing illumination units (6, 7) to light, it is possible to see through blood vessels. As a result, the location of blood vessels can be accurately ascertained. Due to these suction, injection, and exclusion functions, endoscopic surgery can be safely conducted.

Description

Luminescent suction injection pressure exhaust tube for endoscopic surgical forceps

The present invention relates to a luminescent suction / injection / pressure-extraction cylinder for endoscopic surgical forceps that functions as tissue fluoroscopy, aspiration, injection, and exclusion device during endoscopic surgery such as laparoscope and thoracoscope.

Conventionally, in laparotomy and thoracotomy, as a method of grasping the position of the blood vessel, the artery is palpated (tactile) with the operator's finger, and illumination light is applied from the back of the target tissue to make the blood vessel visible. There is a way to recognize. However, in laparoscopic surgery and thoracoscopic surgery, the operator cannot touch the artery (tactile sense) with a finger. In other words, laparoscopic surgery and thoracoscopic surgery have the advantage that the wound can be reduced compared with conventional open surgery and thoracoscopic surgery, reducing the burden caused by surgery, and quick recovery after surgery, In laparoscopic surgery and thoracoscopic surgery, the position of blood vessels buried in fat is determined only from the images taken by the camera, and it is difficult to grasp blood vessels in cases with a lot of fat. There is a disadvantage that the operation time becomes longer. Conventionally, there has been no suitable device for illuminating the blood vessel by applying illumination light from the back of the tissue.

Here, Patent Document 1 discloses an illumination device used in laparoscopic surgery and thoracoscopic surgery. This illuminating device has a cylindrical light emitting tube, and can illuminate the inside of the body by being provided in a port.

JP 2006-166969 A

However, in laparoscopic surgery and thoracoscopic surgery, it is not easy to move the organ, and there is no space for introducing lights or the like from the port into the body to illuminate the blood vessels in the organ. In the above-mentioned Patent Document 1, since it is a lighting device provided in a port, it cannot be introduced into the body. Therefore, it did not function as an illumination device for sufficiently grasping blood vessels in an organ in laparoscopic surgery and thoracoscopic surgery. As described above, in laparoscopic and thoracoscopic operations, an apparatus suitable for grasping the position of a blood vessel buried in fat has not been realized.

The present invention has been made paying attention to the above circumstances, and its purpose is to accurately recognize the position of the blood vessel by illuminating the tissue or organ to be excised and seeing through the blood vessel, and to detect the target lesion. An object of the present invention is to provide a luminescent suction injection pressure discharge outer cylinder for endoscopic surgical forceps for safe excision and shortening of time.

In order to solve the above technical problem, a luminescent suction injection pressure discharge outer cylinder for endoscopic surgical forceps according to one aspect of the present invention is an outer cylinder that is attached to a forceps during endoscopic surgery, and has a cylindrical shape. A housing, a front irradiation light emitting unit provided at the upper part of the front surface of the housing, a side irradiation light emitting unit provided above the front surface of the peripheral surface of the housing, the front irradiation light emitting unit, and the side irradiation. A light emission control unit that controls light emission of the light emitting unit, and a hollow portion that is hollow in a cylindrical shape at substantially the center of the casing and into which the forceps can be inserted, are provided.

According to the luminescent suction / injection pressure / exhaust tube for endoscopic surgical forceps according to the present invention, the position of the blood vessel is accurately recognized by applying light to the tissue or organ to be excised and seen through the blood vessel, so that the target lesion can be safely detected. It is possible to cut out and shorten the time.

The housing 152 includes a lumen portion 161 that is hollow in a cylindrical shape at the center thereof. The lumen 161 extends from the front surface 154 to the rear surface 5 of the housing 152 and makes the housing 152 hollow. Furthermore, a drainage groove 162 is provided below the lumen portion 161 so as to be continuous with the lumen portion 161. The end surface of the drainage groove 162 is inclined in accordance with the inclination of the front surface 154 and extends from the front surface 154 of the housing 152 to the vicinity of the rear surface 5, and the end portion near the rear surface 5 of the drainage groove 162 is the drainage tube 14. It is connected to the. In addition, an injection hole 163 is provided below the drainage groove 162 so as to protrude forward independently of the drainage groove 162. The injection hole 163 extends from the front surface 154 of the housing 152 to the vicinity of the rear surface 5, and the end near the rear surface 5 of the injection hole 163 is connected to the injection tube 15.

In this way, the injection hole 163 on the front surface 154 has a slightly protruding tip shape, and the tip portion where the lower injection hole 163 is inclined at a predetermined angle and protrudes slightly is pressed against the tissue with hard rubber or the like. It may be changed.

As described above, according to the tenth embodiment of the present invention, the injection hole 163 portion at the lower part of the front surface 154 of the casing 152 protrudes, and is composed of hard rubber or the like, and deforms when pressed against the tissue. A luminescent suction injection pressure discharge outer cylinder for endoscopic surgical forceps that can be used is provided.

The first to tenth embodiments of the present invention have been described above, but the present invention is not limited to this, and various improvements and modifications can be made without departing from the gist of the present invention. For example, when hemostasis is performed, not only the forceps but also an endoscope may be placed in an outer cylinder, or an electric knife, an ultrasonic coagulation incision device, or a blood vessel sealing system device may be placed therein. Further, a plurality of flaps and balloon thrust flaps may be provided.
