Description

  The present invention relates to a forceps, and more particularly to a scaled forceps formed so that selection of a surgical suture instrument and the like can be performed easily and quickly.

  Conventionally, as this type of forceps, for example, when inserting into a blood vessel, there is one in which a scale is engraved on a forceps member that opens and closes so that the distance from the distal end becomes clear (see, for example, Patent Document 1). .

By the way, for example, when creating a passage by connecting different parts of the same organ or between different organs, conventionally, a surgeon selects a suture device or the like suitable for the size of the part based on experience and intuition. This is usually done.
Therefore, conventionally, in the case of this type of operation, it is inevitable that differences in operation time and suturing skill occur depending on the skill level of the doctor.
JP 2002-253553 A

The present invention has been proposed in view of such conventional situations.
Therefore, the technical problem to be solved by the present invention is that an optimal surgical suturing device is obtained from the length and thickness of the diameter of a human body part such as a flattened intestine by sandwiching a human body part such as the intestine between a pair of holding parts. It is an object of the present invention to provide a forceps with scales that can be selected easily and quickly.

The present invention employs the following technical means in order to solve the above problems.
That is, as shown in FIG. 1 and the like, the present invention includes a pair of holding parts 2 for holding a human body part 1, and a holding part 4 for opening and closing the holding part 2 via a pivoting place 3. The above-mentioned clamping part 2 is provided with a scale 5 for reading the length of the human body part 1 that is sandwiched and flattened by the clamping part 2. (Claim 1).

In this case, it is preferable that the scale 5 for reading the thickness of the human body part 1 to be flattened by being sandwiched by the sandwiching part 2 is attached to the protruding piece 6 inside the handle 4b of the gripping part 4 in the present invention. (Claim 2).
This is because an optimal surgical tool can be selected with reference to the thickness of the flat human body part 1.

Moreover, as another structure which achieves the subject of this invention, as FIG. 1 etc. show, a pair of clamping part 2 for clamping the human body site | part 1 and this clamping part 2 via the pivot attachment location 3 are used. A human body that is formed with a grasping portion 4 for opening and closing operation, and is flattened by being pinched by the protruding portion 6 inside the handle 4b of the holding portion 4 by the holding portion 2. Some have a scale 5 for reading the thickness of the part 1 (Claim 3).
In the case of the present invention, an optimal instrument used for anastomosis and suture can be easily and quickly selected from the thickness of the tissue.

Thus, in the case of the present invention, the scale 5 may be formed of a numerical value 5a and a mark 5b for displaying the length indicated by the numerical value 5a in cooperation with the numerical value 5a. .
This is because, according to this, compared with the case where the scale 5 is read one by one, the length and thickness can be known immediately from the numerical value 5a, and the time for selecting the appliance can be reduced accordingly.

In the present invention, a scale for reading the length and thickness of the human body part that is sandwiched between the pair of sandwiching parts and flattened is attached to the pair of sandwiching parts.
Therefore, according to the present invention, an optimal suture device or the like used for anastomosis can be selected easily and quickly from the length and thickness of the flattened human body part.

Hereinafter, the best mode for carrying out the present invention will be described.
As shown in FIG. 1 and the like, the forceps according to the present invention includes a pair of clamping parts 2 for clamping a human body part 1 and a gripping part 4 for opening and closing the clamping part 2 via a pivoting part 3. And is formed. The grip portion 4 is formed with a finger hole 4a for inserting a finger.

  In the present invention, a scale 5 for reading the tube diameter of, for example, a tubular human body part 1 that is sandwiched and flattened by the sandwiching part 2 is attached to the sandwiching part 2. In this embodiment, the scale 5 is attached to the clamping unit 2 in units of 5 mm over the longitudinal direction.

  Further, according to the present invention of this embodiment, the protruding piece 6 inside the handle 4b of the gripping part 4 is provided with a scale 5 for reading the thickness of the tubular human body part 1, for example, which is sandwiched between the clamping parts 2 and flattened. Has been. The scale 5 is provided, for example, in units of 0.5 mm over the longitudinal direction of the protruding piece 6.

  Reference numeral 7 denotes an indicator piece protruding inward so as to rub against the protruding piece 6 inside the handle 4b on the other side. A reference line 8 is attached to the tip of the indicating piece 7, and the reference line 8 is positioned so as to be arranged at a position “0” of the scale 5 when the clamping unit 2 is closed. In addition, 9 is a spring member interposed between the handles 4b.

Next, a usage example of the product of the present invention according to this embodiment will be described.
First, the user pushes the grip portion 4 outward, opens the pair of sandwiching portions 2, and places the tubular human body part 1 such as the intestine between the pair of sandwiching portions 2. Next, the user closes the gripping part 4 in this state, uses the restoring force of the spring member 9 to sandwich the human body part 1 flatly with the clamping part 2, and uses the scale 5 attached to the clamping part 2. And read the tube diameter. Further, from the scale 5 of the protruding piece 6, the value indicated by the reference line 8 is read, and the thickness is calculated. Then, based on these readings, the most suitable suture device for stitching the human body part 1 is selected.

In the above place, in the above example, the scale 5 is provided on the protruding piece 6 together with the sandwiching portion 2 and the thickness of the human body part 1 such as the tube diameter is measured so that the thickness can be measured. Only one of them may be provided.
In the present invention, the type and structure of the forceps are not limited to the intestinal forceps as in the above example, but are arbitrary. That is, the present invention can be used for a surgical operation using an endoscope having a long shaft as shown in FIG. 2, for example, as shown in FIG. The forceps may be used.

  Further, as shown in FIGS. 5 and 6, the protruding piece 6 is passed through the other handle 4 b and is formed so that the value indicated by the inner edge or the outer edge of the handle 4 b can be read as the thickness. It's okay. 4b1 is a hole that is penetrated by the other handle 4b to allow the protruding piece 6 to pass through. In the case of the present invention, since the indication piece 7 can be omitted, the sliding contact operation between the protruding piece 6 and the indication piece 7 can be wiped out, and the holding portion 4 can be smoothly opened and closed accordingly. In this case, the scale 5 can be read as long as the protruding piece 6 is passed through the other handle 4b even if the grip portion 4 is opened wide. Therefore, according to this, there is an advantage that the measurement range becomes larger than the case of using the indication piece 7.

Further, as shown in FIGS. 9 and 10, the scale 5 may be formed of a numerical value 5a and a mark 5b that displays the length indicated by the numerical value 5a in cooperation with the numerical value 5a. In this embodiment, the numerical value 5a is “30” and “20”. And the mark 5b which displays the space | interval corresponding to 30 mm or 20 mm which is the length which this numerical value 5a shows is formed with a pair of division line 5b1 and the arrow line 5b2 currently displayed on the both sides of the numerical value 5a. Yes.
In the case of this embodiment, the approximate length of the flat human body part 1 can be quickly read based on the scale 5. Therefore, according to this, selection of a suture instrument can be speeded up and facilitated accordingly.

  Further, in the case of this embodiment, when a plurality of numerical values 5a are written together, as shown in FIG. 11, it is preferable to share one partition line 5b1 and display it with one line. Because, in this case, one edge 1a of the human body part 1 is aligned with the lane marking 5b1 on one side, and the tube diameter and the like can be read by appropriately referring to the interval display mark 5b indicated by each numerical value 5a. This is because the reading operation can be performed easily and quickly.
