JPH11137558A - Medical treatment tool for fixing dissected part - Google Patents

Abstract

PROBLEM TO BE SOLVED: To safely fix a dissected part under dissected condition and to perform a surgical operation rapidly, surely and with extremely high safety without requiring an assistant in a dissection operation wherein in the conventional operations, after a part to be dissected is dissected, the end parts are pressed by an assistant or by using a tool as a wt. to perform the action and therefore, the assistant is inevitably required and there exists even possibility of going backward to safety and speedup of the operation. SOLUTION: The medical treatment tool for fixing dissected part consists of two base lines 4 providing an approximately guitar-shaped crosssection with a top ball 2 and a bottom ball 3 being continued at a constricted part 1, two arc-like narrow lines 5 and several pieces of needles 6 and the two arc-like narrow lines 5 are turned upward in the neighborhood of facing both end parts of the two base lines 4 and the several pieces of needles 6 are fixed in each constricted part of the two base lines 4 so as to face them horizontally to the outside.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical instrument for fixing an incision.

[0002]

2. Description of the Related Art Conventionally, in incision surgery on a human body or an animal, an incision is opened outward, and an end of the incision is pressed by an assistant or pulled by using an appropriate tool such as tweezers or scissors. , Holding down and performing surgery.

[0003]

In the above-mentioned prior art, an assistant is always required even if an appropriate tool is applied, and the incision state of the incision is smooth, and
It is not always safe and secure, but rather prone to instability, impairs safety when performing surgical procedures,
There were inefficient problems. The present invention provides a medical instrument for fixing an incision, which aims to be able to perform a surgical operation safely and quickly at the same time while ensuring that the incision remains open on both sides without the need for an assistant. It was developed.

[0004]

In order to achieve the above object, the present invention comprises two base lines having a substantially gourd-shaped cross section having an upper ball and a lower ball continuous at a constricted portion, and two arc-shaped base lines. It consists of a thin wire and several needles, and the two arc-shaped thin wires are directed upward near both opposing ends of the two baselines, and several needles are placed horizontally outward on the two baselines. It is another object of the present invention to provide a medical instrument for fixing an incision, wherein the medical instrument is fixed to each of the constrictions.

According to the present invention, when the two base lines are compressed and set in the incision, the compressed base line is restored to its original form by the elastic reaction force of the two arc-shaped thin lines, The needle is inserted into the incision, and the ends of the incision are stably fixed over the respective arcuate thin lines. This means that the state in which both ends of the incision portion are widened can be secured with one touch.
The operation can be performed within the frame of two base lines and two arc-shaped thin lines. Further, when the surgical operation is completed, the two baselines can be picked up and compressed very easily by compressing them.

The cross-sectional shape of the base line is substantially a gourd-shaped curved outline, and the arc-shaped thin wire and the fixing portion of the needle are all hidden in the constricted portion. The contact is soft, and no damage is caused even when touched, and the safety is extremely high. Further, since the constricted portion has the function of a gutter or a groove, the blood flow is directional and hardly adheres. Furthermore, if stainless steel is used for all the materials, it is hard to rust and can withstand long-term use, and it is also possible to integrally mold with a mold using synthetic resin. The base line can be appropriately designed and changed to a straight line, an arc-shaped curve, or the like, and a suitable one is selected and applied depending on the form of the incision.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION A base line 4, an arc-shaped thin wire 5 and a needle 6 consisting of an upper ball 2 and a lower ball 3 which are continuous at a constricted portion 1 are each manufactured in advance in a predetermined shape and size using stainless steel. The constricted portions 1 of two identical and curved base lines 4 were drilled in advance. Then, the respective ends of the same two arc-shaped fine wires 5 are horizontally bent 90 degrees from the inside of the constricted portions 1 into the small holes 7 near the respective ends of the two parallel base lines 4. When it protrudes outside the base line 4, it is bent 90 degrees along the outside of the constricted portion 1, further bent 90 degrees and embedded in the small hole 7 toward the inside of the constricted portion 1 and fixed. Baseline 4
And two arc-shaped thin wires 5 were connected. Further, the needles 6 are inserted into the small holes 7 on the outside of the constricted portion 1 of the base line 4, and their ends are bent 90 degrees along the inside of the constricted portion 1, further bent 90 degrees inward, and inserted into the small holes 7. With
Further, it was bent inward by 90 degrees and fixed to the base line 4 along the outside of the constricted portion 1. The arc-shaped thin wire 5 and the needle 6 are securely fixed to the two base lines 4, and their fixed portions are accommodated in the constricted portion 1 and the small hole 7 and do not protrude. By appropriately changing the size, size, thickness, and the like of the two base lines 4 and the two arc-shaped thin lines 5, it is possible to cope with the application location.

[0008]

According to the present invention, the incision can be securely attached and detached with a single touch, so that no assistant is required when performing the incision operation, and the operation can be speeded up and safety and reliability can be maintained.
