場合よりも大なる引張り強度を示す。FIG. 3 is an enlarged view of a main part of an embodiment of an endoscope treatment instrument lifting device according to the present invention. In FIG. 3, reference numeral 21 denotes an operating wire made of stranded wires such as stainless steel, and a plastically deformable cylindrical socket 23 having an inner diameter slightly larger than the outer diameter of the operating wire 21 is attached to the tip surface of the operating wire. The outer periphery of the socket metal 23 is squeezed by swaging or drawing processing, plastically deformed, and fixed by pressure, thereby forming an engaging portion for the stepped portion of the stepped through hole 25 of the treatment platform 24. It is something to do. At this time, as shown in FIG. 3, if an uneven rough surface 22 is formed in advance by sandblasting or the like on the surface of the tip of the operating wire, the inner circumference of the socket 23 to be crimped and fixed will be similar to the operating wire 21. The socket holder 23 bites into the uneven rough surface portion 22 and is fixedly connected to the operation wire by mechanical unevenness retention, so it exhibits greater tensile strength than when simply crimped and fixed.

着させることができる。Further, when the uneven rough surface part 22 is formed on the surface of the tip end of the operating wire 21, and the socket metal 23 is further crimped with an adhesive 26, and the adhesive 26 is hardened and fixed,
In addition to the bonding effect caused by the biting of the socket piece 23 into the uneven rough surface portion 22 of the operating wire 21, the adhesive effect of the adhesive 26 interposed between the contact surfaces increased by the uneven contact between them is added, and the operating wire 2] and the socket are bonded together. The cap 23 can be fixed even more firmly.

．． At the tip of the 6 mm operating wire, an inner diameter of 0.65 mm,
A stainless steel socket with an outer diameter of 2.3mm and a length of 23mm is inserted into the socket, and the operating wire is formed by plastic deformation processing to reduce the outer diameter of the socket to 2.2 nm. The experimental data of the tensile strength of the connection part and the surface of the tip of the operating wire with the above structure are sand-blasted with Alundum No. 30 to form an uneven rough surface. With or without applying adhesive, insert the socket with the above configuration into the socket with the same outer diameter (
Table 1 shows experimental data on the tensile strength of the connecting portions of the operating wires formed by plastic deformation processing to reduce the thickness to 2.2 mm.

とができる。In addition, as for the adhesive, if the purpose is only to prevent the penetration of chemical liquids, etc., it is possible to apply ceneal adhesive, which does not have much adhesive strength, and the socket plate is made of stainless steel. However, any material that can be plastically deformed can be used, and plastics other than metal can also be used.

や腐食を防止することができる。As described above based on the embodiments, the present invention involves attaching a socket metal crimped and fixed to the outer periphery of the end of the operating wire by plastic deformation to the stepped part of the stepped through hole provided in the raising table.
The operation wire and the two lifters are connected to form the endoscope treatment instrument lifting device, so it is easy to use when fixed with silver soldering.
The fixed part between the operation wire and the socket piece does not deteriorate due to chemicals, etc., and the tensile strength can be increased and stabilized. Also, unlike silver soldering, heating or flux is not used. , it is possible to prevent a decrease in tensile strength and corrosion of the operating wire.

Not only can the tensile strength be further increased, but also effects such as being able to prevent the chemical solution from penetrating into the inside of the operating wire strand can be obtained.
