Four-connecting-rod movable rotating mechanism and hemostatic forceps with four-connecting-rod movable rotating mechanism

Abstract

The invention discloses a four-connecting-rod movable rotating mechanism and hemostatic forceps with the four-connecting-rod movable rotating mechanism. The four-connecting-rod movable rotating mechanism comprises a head, a connecting sheet, a supporting frame, a lining, a pull rod, a plastic-coated spring pipe and a rotating steel wire; the head is fixedly connected with the connecting sheet; thesupporting frame is riveted with the head part; the connecting sheet is riveted with the pull rod; the supporting frame is freely, movably and rotatably connected with the lining; the lining is welded with the plastic-coated spring tube; the pull rod is fixedly connected with the rotating steel wire; and the front section of the rotating steel wire is inserted into the plastic-coated spring tube.The haemostatic forceps further comprise a handle rotating mechanism; the handle rotating mechanism comprises an outer sheath tube interface, a fixed handle, a rotating handle core, a movable handle,a rotatable handle and a power supply clip; and the four-connecting-rod movable rotating mechanism is connected with the handle rotating mechanism through the plastic-coated spring tube and the rotating steel wire. The hemostatic forceps disclosed by the invention can fix the handle and can singly rotate the head, so that the risks of internal organ tissue damage, damage of combined endoscope, etc., caused by rotating the hemostatic forceps in an operation can be avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a high-frequency hemostatic device, in particular to a four-link movable rotating mechanism and a hemostatic forceps with a four-link movable rotating mechanism. Background technique [0002] In the medical procedures of the hospital, targeted treatment is usually performed on the target area in the patient's body, including high-frequency cutting and hemostasis. During the treatment process, hemostatic forceps are required, and it is required to be able to precisely locate and clamp the bleeding point to limit damage to surrounding healthy tissues. [0003] However, in practical applications, during the operation of clamping with hemostats, due to the mobility of tissues in the bleeding point area, such as the mobility of internal organ tissues in the respiratory system and digestive system, the traditional four-link structure The hemostat can either not be rotated, or th...

Problems solved by technology

[0003] However, in practical applications, during the operation of clamping with hemostats, due to the mobility of tissues in the bleeding point area, such as the mobility of internal organ tissues in the respiratory system and digestive system, the traditional four-link structure Hemostatic forceps, either cannot be rotated, or the handle can only be used to drive the entire hemostatic forceps including the spring tube and forceps head to rotate at the same time, while the entire hemostatic forceps rotates, there is a risk of damage to internal organs and tissues, and damage to the combined endoscope.

[0004] In view of the fact that the traditionally used four-link structure hemostat cannot fix the handle and only rotate the head, which will lead to risks during the operation.
