Description

  The present invention relates to an endoscopic surgical scissor, and more particularly to an endoscopic surgical scissor suitable for minimum wound endoscopic surgery.

  Conventionally, as a surgical operation in the medical field, laparotomy in which a lesion is removed after making a large incision in the skin has been the mainstream. Since the abdominal operation makes a large incision in the abdominal surgery, a sufficient field of view can be secured during the surgery, and a sufficient space for using various surgical instruments can be secured.

  In recent years, laparoscopic surgery that enables surgery on a lesion without incising the skin is known. Laparoscopic surgery is a surgical procedure in which several small holes are made in the abdominal wall, an endoscope or surgical instrument is inserted from there, and gas is injected to operate the abdominal cavity. However, it is used in various fields because it can reduce the burden on patients due to surgery.

  However, laparoscopic surgery is important for safety, speed, sensitivity, cost, etc., such as complications caused by gas injection, intestinal obstruction due to intra-abdominal wounds, and increased costs due to the use of expensive special instruments. There is an aspect that sacrifices a serious problem. For this reason, in reality, the burden on the patient may be increased excessively. Therefore, a minimum wound endoscopic operation was developed.

  The minimum endoscopic surgery is a surgical method in which a few transverse fingers are incised through the skin and an endoscope, a surgical instrument, and the like are inserted into the body through the incision. In other words, the skin is incised as in a conventional laparotomy, but the incision size is kept to a minimum to reduce the burden on the patient, and the above problems are solved. This is a surgical method with improved sex. This minimum endoscopic surgery has been actively carried out in recent years, and it has been proved that it is a very effective surgical method for malignant tumor surgery and adrenal surgery of the prostate, kidney and bladder.

  By the way, in a minimum wound endoscopic operation, unlike an abdominal operation, it is necessary to secure an insertion path from an incision wound of a surgical instrument such as an endoscope. Here, a surgical scissors is used to secure an insertion path for the surgical instrument in a state where the incision is opened. However, since the conventional surgical scissors are premised on use for open surgery, they cannot be used for minimal wound endoscopic surgery with several incisions. In addition, when a surgical scissors is created in accordance with the size of the incision, the surgical instrument cannot be inserted into the body from the incision.

  In view of the above circumstances, an object of the present invention is to provide an endoscopic surgical scissors that is particularly suitable for minimum wound endoscopic surgery.

An endoscopic surgical scissors according to the present invention is an endoscopic surgical scissors that is inserted into the body and used during endoscopic surgery.
A grasping portion grasped by an operator;
A neck portion having a predetermined width, which includes a first portion extending straight from the grip portion and a second portion extending from the first portion by bending approximately 90 degrees;
The neck portion extends straight from the neck by a predetermined length, is wider than the predetermined width, and the tip portion is formed from a hook portion having a hook shape.

  In the endoscopic surgical scissors according to the present invention, it is preferable that the boundary between the neck and the scissors is formed so as to be tapered.

  Moreover, it is preferable that the width | variety of the said collar part is 20 mm or more and 60 mm or less, Furthermore, it is preferable that the width | variety of the said neck part is 5 mm or more and 30 mm or less.

  Further, it is preferable that an insertion length, which is a distance from the first portion of the neck portion to a straight line parallel to the first portion and passing through the tip portion of the collar portion, is 10 cm or more and 30 cm or less.

  The above-mentioned setting range of the width of the buttock is set in consideration of the size of the incision formed in the human body in the minimum wound endoscopic operation targeted for the endoscopic surgical heel of the present invention It is. That is, if it is larger than the set range, it is necessary to increase the size of the incision, which increases the burden on the patient. On the contrary, if it is smaller than the set range, the burden on the patient can be reduced, but it becomes difficult to keep the incision open. Therefore, the above setting range is appropriate. In addition, the patient's physique ranges widely, such as a child and an obese adult, and the size of the incision varies depending on the physique of the patient, but is usually 2 to 8 cm.

  In addition, the setting range of the width of the neck is considered so that other surgical instruments such as an endoscope and an incision instrument can be inserted from the incision while the buttocks are inserted into the body. It is set. That is, if it is larger than the set range, other surgical instruments such as an endoscope and an incision instrument cannot be inserted from the incision. Conversely, the strength of the neck becomes weaker than the above setting range. Therefore, the above setting range is appropriate.

  In addition, the setting range of the insertion length is set in consideration of the length from the incision to the lesion targeted for the minimum wound endoscopic operation. That is, in the minimum wound endoscopic operation, the depth of the lesion varies depending on the physique of the patient (that is, whether it is thin or fat), but is generally in the range of about 10 to 30 cm from the incision. If the length is longer than this, the first part of the grasping part and the neck part floats from the patient's body, and thus the endoscopic surgical scissors of the present invention cannot be used stably. If the length is shorter than this, the tip of the endoscopic surgical scissors of the present invention may not reach the lesion. Therefore, the above setting range is appropriate.

  Here, the endoscopic surgical scissors according to the present invention can be used for patients of various physiques by making them so as to have various insertion lengths within the above-mentioned setting range. In particular, in the case of a fat patient, it is necessary to cut open the internal tissue from the incision until reaching the lesion. First, use an endoscopic surgical scissors with a short insertion length, and gradually increase the insertion length. By exchanging with a long-lasting surgical scissors, it becomes possible to reliably reach the lesion from the incision.

  In addition, the setting range of the width and insertion length of the buttocks and neck is a practically preferable guideline, and can open and hold the incision and can insert a surgical instrument from the incision. If so, the width or length may be slightly out of this range.

  The endoscopic surgical scissors according to the present invention configured as described above has a width wider than a predetermined width of the neck and is composed of a distal end portion or a scissors shape having a scissors shape. Since a space can be secured between the incision and the neck in a state where the incision is widened, it becomes easy to insert another surgical instrument such as an endoscope from the incision into the body.

  In addition, by forming the boundary between the neck and the buttocks in a tapered manner, there is no corner at the boundary between the neck and the buttocks in the endoscopic surgical scissors of the present invention, Thereby, the damage of the body tissue by the endoscopic operation scissors according to the present invention can be prevented.

  In addition, when the width of the buttock, the width of the neck and the insertion length of the present invention are set to a width and length suitable for minimum endoscopic surgery, when performing minimum endoscopic surgery Further, there is an effect that operability can be improved.

  Hereinafter, embodiments of an endoscopic surgical scissors according to the present invention will be described with reference to the drawings.
